Description

Through link beam management method, device, equipment and readable storage medium

Technical Field

The embodiments of the present invention relate to, but are not limited to, the field of communications, and in particular, but not limited to, a method, an apparatus, a device, and a readable storage medium for direct link beam management.

Background

The vehicle networking refers to a large system network for wireless communication and information exchange between vehicles-X (X: vehicles, pedestrians, roadside equipment, the Internet and the like) according to an agreed communication protocol and a data interaction standard. The vehicle can obtain safe driving, high traffic efficiency and convenient or entertainment information through the Internet of vehicles communication. Classified from the objects of wireless communication, internet of vehicles communication includes three different types: vehicle-to-Vehicle communication (V2V for short), vehicle-to-Infrastructure/Vehicle-to-Network communication (V2I/V2N for short), and Vehicle-to-Pedestrian communication (V2P for short), collectively referred to as V2X communication.

In the study of LTE (Long Term Evolution) based V2X communication organized by 3GPP (3 rd Generation Partnership Project), a V2X communication method based on a direct link (also referred to as a sidelink link) between User equipments (users, abbreviated as UEs) is one of ways implemented by the V2X standard, that is, service data is not forwarded through a base station and a core network, as shown in fig. 1, UE1 directly transmits service data to UE2 through an air interface (an interface introduced in 3GPP Rel-12 for direct interaction between UE and UE, referred to as a PC5 interface), or UE3 directly transmits service data to UE1 through an air interface, and such a V2X communication mode may be abbreviated as PC5-based V2X communication or V2X sidelink communication.

With the technological progress and the development of automation industry, the V2X communication scenario is further extended and has higher performance requirements. The 3GPP has already established research on car networking communication based on fifth Generation mobile communication technology (5g, 5th Generation), including car networking communication based on a 5G air interface and car networking communication based on a 5G direct link (NR sidelink). The 5G direct link communication can support broadcast, multicast and unicast communication; when the 5G direct link communication adopts the unicast communication, if the unicast communication has a direct link beam failure (also referred to as a direct link beam failure) sidelink beam failure, the communication service may be interrupted. Therefore, when the through link beam fails in unicast communication, how to recover the through link beam to ensure service continuity is a technical problem that needs to be solved urgently at present.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.

The first embodiment is as follows:

in order to reduce the possibility of service interruption caused by occurrence of a sidelink beam failure in the unicast communication or other types of communication as much as possible, the method for managing a straight-through link beam provided in this embodiment may first acquire sidelink beam failure recovery configuration information (i.e., sidelink beam failure recovery configuration information), and may further perform beam failure recovery processing according to the acquired sidelink beam failure recovery configuration information, so that when a straight-through link beam failure occurs in the unicast communication or other types of communication, recovery of a straight-through link beam is performed as soon as possible to ensure service continuity.

Alternatively, in this embodiment, it may be set that only one UE performs direct link beam management (e.g., performs sidelink beam failure recovery) for the user equipments UEs at both sides of communication in direct link communication, or it may be set that either UE performs direct link beam management. For convenience of understanding, in this embodiment, a UE on a party initiating direct link beam management (e.g., sidelink beam failure recovery) may be referred to as a source UE, and a UE on a communication opposite end of the source UE is referred to as a target UE. For example, still illustrated in the application scenario shown in fig. 1. For two communication parties UE1 and UE2 of the direct link communication in fig. 1, when UE1 executes direct link beam management, UE1 is a source UE, and UE2 at the opposite end is a target UE; when UE2 performs direct link beam management, UE2 is the source UE, and UE1 at the opposite end is the target UE. Of course, in some examples, it is not excluded that UEs (e.g., UE1 and UE 2) of both communication parties perform direct link beam management simultaneously, where UE1 is a source UE, UE2 is a target UE, UE2 is also a source UE, and UE1 is also a target UE.

And it should be understood that the UE in this embodiment may be any user equipment capable of performing sidelink communication, including but not limited to a user terminal, various vehicle-mounted terminals on a vehicle, and other communication terminals outside the vehicle (including but not limited to a roadside, a parking spot, a gas station, a charging station, etc.) capable of communicating with the user terminal and/or the vehicle-mounted terminal.

For ease of understanding, the present embodiment is exemplified below with direct link beam management methods of a source UE side and a target UE side, respectively.

For the source UE side, the direct link beam management method thereof is shown in fig. 2, and may include but is not limited to:

s201: and acquiring the direct link beam failure recovery configuration information.

It should be understood that the acquisition of the through-link beam failure recovery configuration information in the present embodiment is not acquired in real time every time the through-link beam failure recovery is performed. In some examples, the through-link beam failure recovery configuration information may be obtained only once and saved after the obtaining for use in through-link beam failure recovery. In some examples, after the direct link beam failure recovery configuration information, when the direct link beam failure recovery configuration information is updated, the updated direct link beam failure recovery configuration information is obtained again for use in direct link beam failure recovery.

In this embodiment, the manner of obtaining the direct link beam failure recovery configuration information may be flexibly set, for example, in an example, the direct link beam failure recovery configuration information may be obtained through at least one of the following manners:

the method I comprises the following steps: acquiring straight-through link beam failure recovery configuration information from a base station;

in this embodiment, the direct link beam failure recovery configuration information may be obtained through Radio Resource Control (RRC) communication information, which includes but is not limited to, that is, the base station may send the direct link beam failure recovery configuration information to the UE through various RRC communication information.

The second method comprises the following steps: acquiring direct link beam failure recovery configuration information from User Equipment (UE) of a communication opposite end;

as can be seen from the above analysis, in this embodiment, the UE of the correspondent node is the target UE. In an example, the target UE may send the direct link beam failure recovery configuration information to the source UE actively or according to a request of the source UE. The interaction of the direct link beam failure recovery configuration information between the source UE and the target UE may be performed through, but not limited to, at least one of the following messages:

PC5 connection establishment message (or called PC5 connection request message), PC5 connection establishment response message, PC5 bearer configuration response message, PC5 reconfiguration message, and direct link beam failure recovery configuration message (i.e. sidelink beam failure recovery configuration message).

The third method comprises the following steps: acquiring straight-through link beam failure recovery configuration information from the pre-configuration information;

it should be understood that, in this mode, the pre-configuration information may be configured directly on the UE, or may be configured on other devices dedicated to configuring the direct link beam failure recovery configuration information for the UE.

S202: and according to the acquired straight-through link beam failure recovery configuration information, performing beam failure recovery processing.

In this embodiment, performing the beam failure recovery processing according to the acquired through link beam failure recovery configuration information includes:

and according to the through link beam failure recovery configuration information, when detecting that the through link beam failure recovery condition is triggered, executing a through link beam failure recovery process, wherein the process comprises the step of sending a beam failure recovery processing message to the opposite terminal UE for beam recovery processing.

In one example of this embodiment, the through link beam failure recovery configuration information may include, but is not limited to, at least one of:

whether to synchronize source UE indication information, supported direct link sidelink discovery mode indication information, a beam failure detection resource (i.e. beam failure detection resource), a beam failure detection timer (i.e. beam failure detection timer), a maximum beam failure instance number (i.e. maximum beam failure instance number), a candidate beam resource (i.e. candidate beam resource), a beam failure recovery timer (i.e. beam failure recovery timer), a beam failure recovery request retransmission timer (i.e. beam failure recovery request retransmission timer), a beam failure recovery request retransmission maximum number (i.e. beam failure recovery request retransmission maximum number), a beam failure recovery maximum number (i.e. beam failure recovery maximum number), and a beam quality threshold (i.e. beam quality threshold).

It should be understood that, in this embodiment, the through link beam failure recovery configuration information may specifically include which information of the above information is included, and how the included information is used in combination, and may be flexibly selected according to a specific application scenario.

In one example of this embodiment, the candidate beam resources may include, but are not limited to, at least one of:

beam index (i.e., beam index), direct link synchronization reference signal (i.e., sidelink synchronization reference signal), direct link discovery signal (i.e., sidelink discovery signal), direct link communication channel measurement signal, dedicated direct link beam measurement signal (i.e., signal dedicated to sidelink beam detection), direct link synchronization resource (i.e., sidelink synchronization resource), direct link communication resource (i.e., sidelink communication resource for use in sidelink communication), direct link discovery resource (i.e., sidelink discovery resource), beam failure recovery dedicated resource (i.e., beam failure recovery dedicated resource, which may be configured as a resource for specified use in this embodiment, including but not limited to beam resource), beam failure recovery contention resource pool (i.e., beam failure contention resource pool, which in this embodiment is configured as a resource in the beam failure contention resource pool, which may be shared by at least two UEs, including but not limited to beam resource.

For ease of understanding, the present embodiment is described below with an example of detecting whether a through link beam failure recovery condition is triggered.

In this embodiment, the failure of the through-link beam refers to the condition that the quality of the through-link beam has reached the condition that normal communication cannot be performed. The value setting of the threshold value for specifically judging whether the communication can be performed normally can be flexibly set based on factors such as specific communication reliability requirements, communication environments and the like.

In this embodiment, the triggering of the through link beam failure recovery condition may be triggered as soon as the currently used beam is detected to be failed, or may be triggered when the currently used beam is detected to be failed and the failure condition meets a preset failure condition. The specific predetermined failure condition should be understood to be flexibly configurable.

That is, in this embodiment, detecting whether the through link beam failure recovery condition is triggered may include: it is detected whether the currently used beam is failed.

In this embodiment, a method for detecting the beam quality is provided, and the quality detection result may be optionally used as a basis for determining beam failure (the determination of beam failure may also adopt other determination methods), as a basis for selecting a beam, or as a basis for determining whether a beam needs to be reconfigured, and the like, and may be flexibly selected according to specific requirements.

The beam quality measurement method provided by this embodiment includes, but is not limited to, at least one of the following methods:

the first method is as follows: the discovery signal is subject to quality measurements including, but not limited to:

receiving a direct link discovery announcement message sent by opposite terminal UE, measuring beam quality according to the received direct link discovery announcement message, and specifically measuring the quality of a beam receiving the direct link discovery announcement message;

sending a direct link discovery request message to opposite terminal UE, receiving a direct link discovery response message sent by the opposite terminal UE, and measuring the quality of a wave beam required to be measured according to the received direct link discovery response message;

the second method comprises the following steps: when the synchronization source UE is determined to be needed according to the indication information of whether the synchronization source UE exists, receiving a direct link synchronization reference signal sent by the opposite end UE to carry out beam quality measurement;

in this way, the UE at the opposite end may periodically send a direct link synchronization reference signal, and the UE at the home end may measure the quality of the beam currently required to be measured according to the direct link synchronization reference signal sent by the UE at the opposite end;

the third method comprises the following steps: receiving direct link communication channel data sent by opposite terminal UE to measure the beam quality;

in this way, the UE at the opposite end can send data of the direct link communication channel by using the beam failure measurement resource to measure the quality of the beam currently required to be measured;

the method is as follows: and receiving a special direct link beam measurement signal sent by the opposite terminal UE to carry out beam quality measurement.

In this way, the dedicated through link beam measurement signal is transmitted by using the beam failure measurement resource to measure the quality of the beam currently required to be measured.

The dedicated direct link beam measurement signal in this embodiment may be selectively configured to be a signal dedicated to direct link beam measurement, and may also be multiplexed into a signal having other functions according to requirements.

In this embodiment, the beam quality threshold included in the through link beam failure recovery configuration information includes, but is not limited to, at least one of the following:

a direct link synchronous reference signal receiving power threshold; a direct link discovery signal (including but not limited to a direct link discovery advertisement message and/or a direct link discovery response message) receive power threshold; a direct link communication channel receive power threshold; a receive power threshold of the dedicated through link beam measurement signal; a direct link synchronous reference signal receiving signal strength indication threshold; a direct link discovery signal received signal strength indication threshold; a direct link communication channel received signal strength indication threshold; the received signal strength of the dedicated through-link beam measurement signal indicates a threshold.

Of course, it should be understood that the thresholds may be set as other parameter thresholds according to the practical application scenario, besides the received power threshold and the signal strength indication threshold. The threshold in this embodiment may be used as a basis for selecting a beam with good quality, or may be used as a basis for determining that the beam quality is poor, and the specific use and the specific assignment of the threshold may be determined according to a specific application scenario.

In an example of the present example, after detecting that a currently used beam is failed, the triggering may be performed when it is further determined that the failure condition satisfies a preset failure condition. For example, in one example, after detecting that the currently used beam fails, the method may further include:

when the currently used wave beam is detected to be invalid, starting timing through a wave beam invalid detection timer, and adding 1 to a wave beam invalid example counting value;

before the beam failure detection timer is overtime, if the beam failure is detected again, resetting the beam failure detection timer for re-timing, and adding 1 to the count value of the beam failure example; on the contrary, if the beam failure detection timer is overtime, the beam failure is not detected any more, and the counting value of the beam failure example is set to be 0;

in the above process, if the current beam failure instance count value is greater than or equal to the maximum number of beam failure instances, it is determined that the through link beam failure recovery condition is triggered.

By the example mode, the accuracy and the stability of beam failure detection can be improved; it should be understood that the preset failure condition in the present embodiment is not limited to the above example, and for example, n (n may be an integer value equal to or greater than 2) times of beam failures may be continuously detected within a preset time period.

In this embodiment, the manner of sending the beam failure recovery processing message to the peer UE for beam recovery processing may include, but is not limited to, at least one of the following manners:

the first method is as follows: selecting a beam resource (which may be referred to as a target candidate beam resource) from the candidate beam resources, and sending a beam failure recovery request message to the opposite-end UE through the selected beam resource, where the beam failure recovery request message includes identification information of the local-end UE, and here is identification information of the source UE;

when receiving a beam failure recovery response message sent by the peer UE through the beam resource (i.e., the target candidate beam resource), the beam failure recovery is successful, where the beam failure recovery response message includes identification information of the peer UE, and here is identification information of the target UE; in this mode, after determining that the beam failure recovery is successful, the source UE may switch to the beam resource to perform direct link communication with the UE of the opposite end;

it should be understood that the identification information of the UE in this embodiment may be UE identification information (destination layer 2 ID), or pair identification information negotiated by the UE, or other identification information that may be capable of identifying the UE.

The second method comprises the following steps: selecting a beam resource (i.e. the target candidate beam resource) from the candidate beam resources, and sending direct link Control Information (SCI) to the peer UE through the selected beam resource, where the sent direct link Control Information includes but is not limited to at least one of the following:

identification information of the local UE (here, identification information of the source UE), identification information of the peer UE (here, identification information of the target UE), beam failure recovery indication (this embodiment may also be referred to as BFR indication for short), new beam direction, and no data transmission indication information;

in this embodiment, optionally, after receiving the direct link control information on the target candidate beam resource, the UE at the opposite end (i.e., the target UE) may switch to the target candidate beam resource according to at least one of the information included in the direct link control information, and optionally, may also send feedback information used for representing the received SCI or information for confirming beam failure recovery to the source UE; optionally, the source UE may also switch to the target candidate beam resource after receiving feedback information or beam failure recovery confirmation information used to characterize that the UE of the opposite end receives the SCI.

In addition to the above-mentioned exemplary manner, in this embodiment, the beam failure recovery may be performed by using the direct link discovery resource through a direct link discovery signal, for example:

the third method comprises the following steps: when determining that a mode a direct link discovery (i.e., model a sidelink discovery) mode is supported according to the supported direct link discovery mode indication information, sending a direct link discovery advertisement message (i.e., sidelink discovery notification message) in each beam direction, where the direct link discovery advertisement message includes a beam failure recovery indication to be distinguished from other Model a sidelink discovery messages, and optionally may further include identification information of the source UE; the beam failure recovery indication in this embodiment may include, but is not limited to, at least one of a beam recovery flag (i.e., beam recovery flag), a beam switch flag (i.e., beam switch), and a beam update flag (i.e., beam update flag);

and then, receiving PC5 signaling (optionally, the PC5 signaling may include identification information of the target UE) including the new beam direction sent by the peer UE (i.e., the target UE), or receiving PC5 signaling sent by the peer UE in at least one new beam direction (at this time, the PC5 signaling may not include an indication of the new beam direction), where the beam failure recovery is successful.

In this approach, the source UE may switch to the new beam direction for direct link communication with the peer UE after determining that the beam failure recovery was successful.

In this embodiment, when the PC5 signaling including the new beam direction sent by the peer UE (i.e., the target UE) is not received within a certain period of time, the direct link discovery advertisement message may be selectively retransmitted in each beam direction, and the maximum retransmission number may be set.

The method four comprises the following steps: when determining that a mode B direct link discovery (i.e., model B sidelink discovery) mode is supported according to the supported direct link discovery mode indication information, sending a direct link discovery request message in at least one beam direction, where the direct link discovery request message includes a beam failure recovery indication to be distinguished from other Model B sidelink discovery messages, and optionally may also include an identifier of the source UE; the beam failure recovery indication in this embodiment may include, but is not limited to, at least one of a beam recovery flag (i.e., beam recovery flag), a beam switch flag (i.e., beam switch), and a beam update flag (i.e., beam update flag);

and receiving a direct link discovery response message (which optionally may include identification information of the target UE) sent by the peer UE in one beam direction, wherein the beam failure recovery is successful.

In this manner, after determining that the beam failure recovery is successful, the source UE may switch to direct link communication with the peer UE in the beam direction.

In this embodiment, when the direct link discovery response message sent by the peer UE (i.e., the target UE) is not received within a certain time period, the direct link discovery request message may also be selectively retransmitted in each beam direction, and the maximum retransmission number may be set.

Optionally, for the first and second manners, the manner of selecting the beam resource from the candidate beam resources may include, but is not limited to:

the first method is as follows: selecting a beam resource with a beam quality higher than the beam quality threshold from candidate beam resources, for example, selecting a beam resource with a beam quality higher than the beam quality threshold (the specific setting of the threshold can be flexibly set according to an application scenario) from the beam failure recovery dedicated resource and/or the beam failure recovery contention resource pool;

the second method comprises the following steps: selecting a beam resource with the highest beam quality from the candidate beam resources is based on, for example, selecting a beam resource with the highest beam quality from a beam failure recovery dedicated resource and/or a beam failure recovery contention resource pool.

Optionally, when the beam failure recovery processing is executed in the first manner, the following three triggering manners of beam resource reselection may also be included, but are not limited to:

the first method is as follows: after sending a beam failure recovery request message to the opposite terminal UE through the selected beam resource, starting timing through a beam failure recovery request retransmission timer;

when the beam failure recovery request retransmission timer is overtime, if the beam failure recovery response message sent by the opposite-end UE is not received, retransmitting the beam failure recovery request message to the opposite-end UE through the selected beam resource, re-timing through the beam failure recovery request retransmission timer, and recording the retransmission times;

when the retransmission times are larger than the maximum retransmission times of the beam failure recovery request, reselecting a beam resource to send a beam failure recovery request message to opposite-end UE (namely the opposite-end UE);

the second method comprises the following steps: after sending a beam failure recovery request message to the opposite terminal UE through the selected beam resource, starting timing through a beam failure recovery timer;

and when the beam failure recovery timer is overtime, if the beam failure recovery response message sent by the opposite-end UE is not received, reselecting the beam resource to send the beam failure recovery request message to the opposite-end UE.

The third method comprises the following steps: after sending a beam failure recovery request message to the opposite terminal UE through the selected beam resource, starting timing through a beam failure recovery request retransmission timer and a beam failure recovery timer, optionally, the timing value of the beam failure recovery timer is greater than the timing value of the beam failure recovery request retransmission timer;

when the beam failure recovery request retransmission timer is overtime, if a beam failure recovery response message sent by the opposite-end UE is not received, retransmitting the beam failure recovery request message to the opposite-end UE through the selected beam resource, re-timing through the beam failure recovery request retransmission timer, and recording the retransmission times;

and when the retransmission times are more than the maximum retransmission times of the beam failure recovery request and/or the beam failure recovery timer is overtime and does not receive the beam failure recovery response message sent by the opposite terminal UE, reselecting the beam resource to send the beam failure recovery request message to the opposite terminal UE.

In an example of this embodiment, when the beam failure recovery fails, the direct link communication connection may also be selectively disconnected or released, for example, specific control manners include, but are not limited to, the following two manners:

the first method is as follows: when the times of reselecting the beam resource reach the maximum times of beam failure recovery or no beam resource meeting the conditions (for example, but not limited to the completion of the selection of the beam resource or the quality of the remaining beam resource does not meet the requirements) is selected, disconnecting or releasing the through link communication connection with the opposite-end UE;

the second method comprises the following steps: when the number of times of reselecting the beam resource reaches the maximum number of times of beam failure recovery or no beam resource meeting the condition is currently selected, and no data is received from the opposite-end UE within a current preset time period (the current preset time period may be counting from the time when the beam failure is detected for the first time, or counting is determined to be started when the number of times of reselecting the beam resource reaches the maximum number of times of beam failure recovery or no beam resource meeting the condition is currently selected, etc.), the direct link communication connection with the opposite-end UE is disconnected or released.

In an example of this embodiment, when performing the beam failure recovery processing in the fourth manner, at least one beam direction may be directly selected from the candidate beam resources to perform the sending of the direct link discovery request message and the receiving of the direct link discovery response message, and this processing manner has the advantages that discovery periods may not be equal, the efficiency of beam failure recovery may be further improved, and the continuity of the service may be further improved; for example, in an example, when the beam failure recovery processing is performed in the fourth manner, the transmitting the through link discovery request message in at least one beam direction includes:

selecting at least one beam direction from the beam failure recovery dedicated resource and/or the beam failure recovery contention resource pool according to the beam index;

and transmitting the through link discovery request message in the selected at least one wave speed direction.

For the target UE side, the direct link beam management method thereof is shown in fig. 3, and may include but is not limited to:

s301: and receiving a beam failure recovery processing message sent by the opposite-end UE (namely the source UE).

The method for the source UE to transmit the beam failure recovery processing message includes, but is not limited to, the four methods described above.

S302: and performing beam failure recovery processing according to the received beam failure recovery processing message.

For ease of understanding, the present embodiment will be described below by way of example of processing procedures corresponding to the above four modes.

The first method is as follows: receiving a beam failure recovery request message sent by a peer UE (i.e., the source UE) through a beam resource selected from the candidate beam resources (i.e., a target candidate beam resource), wherein the beam failure recovery request message includes identification information of the peer UE (i.e., identification information of the source UE);

sending a beam failure recovery response message on the beam resource (i.e. the target candidate beam resource), and switching to the beam resource to perform direct link communication with the opposite UE, where the beam failure recovery response message includes identification information of the local UE (i.e. identification information of the target UE);

the second method comprises the following steps: receiving through-link control information sent by the opposite-end UE through the beam resource selected from the candidate beam resources (i.e. the target candidate beam resource), wherein the through-link control information comprises at least one of the following: identification information of the local terminal UE (namely identification information of the target UE), identification information of the opposite terminal UE (namely identification information of the source UE), beam failure recovery indication, new beam direction and no data transmission indication information;

and switching to the new beam direction to carry out direct link communication with the opposite terminal UE.

The third method comprises the following steps: receiving a direct link discovery announcement message sent by a peer UE (i.e., the source UE) in each beam direction, where the direct link discovery announcement message includes a beam failure recovery indication, and the beam failure recovery indication in this embodiment may include but is not limited to at least one of a beam recovery identifier (i.e., a beam recovery identifier), a beam switch identifier (i.e., a beam switch), and a beam update identifier (i.e., a beam update identifier);

and sending PC5 signaling including the new beam direction to the peer UE in at least one beam direction, or sending PC5 signaling to the peer UE in at least one new beam direction (at this time, the PC5 signaling may optionally not include indication information of the new beam direction), and switching to the new beam direction to perform direct link communication with the peer UE.

The method is as follows: receiving a direct link discovery request message sent by a peer UE (namely, the source UE) in at least one beam direction (the beam direction may include a beam direction directly selected from the candidate beam resources), wherein the direct link discovery request message includes a beam failure recovery indication;

and in the beam direction of the received direct link discovery request message, selecting one beam direction to send a direct link discovery response message to the opposite terminal UE, and switching to the selected beam direction to carry out direct link communication with the opposite terminal UE.

Optionally, in this embodiment, before receiving the beam failure recovery processing message sent by the peer UE, the direct link beam failure recovery configuration information may also be sent to the peer UE.

Therefore, the through link beam failure recovery method provided by the embodiment can flexibly, quickly and reliably realize the recovery of beam failure when the beam fails, and ensures the continuity of service.

The second embodiment:

the through link beam management method provided in this embodiment may optionally perform the through link beam failure recovery method in the first embodiment, and may further perform beam reconfiguration processing when detecting a beam reconfiguration condition trigger.

Fig. 4 shows a schematic flow diagram of a process of performing beam reconfiguration at a source UE side initiating beam reconfiguration, and the process includes:

s401: and sending a reconfiguration message to the opposite UE in the current used beam direction (namely the source beam direction), wherein the reconfiguration message comprises the selected new beam direction and the identification information of the local UE (namely the source UE).

S402: when receiving a reconfiguration response message sent by the opposite-end UE in the current used beam direction or the new beam direction, switching to the new beam direction to carry out direct link communication with the opposite-end UE, wherein the reconfiguration response message comprises identification information of the opposite-end UE (namely target UE) and/or beam reconfiguration confirmation information.

In one example of this embodiment, the beam reconfiguration condition includes, but is not limited to, at least one of:

the first condition is as follows: the quality of the currently used beam is lower than a preset first beam quality threshold; at this time, the currently used beam may be able to basically maintain normal communication, but the communication effect is not optimal or does not meet the preset normal requirement;

and a second condition: there is currently a beam with a quality above the second beam quality threshold and the quality of this beam is higher than the currently used beam;

the second beam quality threshold is higher than the first beam quality threshold, and the setting of the specific threshold value can be flexibly set according to factors such as specific communication requirements and communication environments.

Of course, it should be understood that other reconfiguration conditions, such as other beams currently existing with a higher quality than the beam currently used, etc., may be flexibly set in addition to the conditions of the above example.

In an example of the present embodiment, the new beam direction selected in S401 may be, but is not limited to, the beam direction with the highest current beam quality, or one of the beam directions in the beam with the beam quality higher than the second beam quality threshold.

As shown in fig. 5, a schematic flow chart of a process of performing beam reconfiguration on a target UE side of an opposite end of a source UE initiating beam reconfiguration includes:

s501: receiving a reconfiguration message sent by a peer UE (i.e. a source UE) in a currently used beam direction, wherein the reconfiguration message comprises the selected new beam direction and identification information of the peer UE (i.e. the source UE).

S502: and sending a reconfiguration response message in the currently used beam direction or the new beam direction, and switching to the new beam direction to carry out direct link communication with the opposite-end UE (source UE), wherein the reconfiguration response message comprises identification information of the local-end UE (namely the target UE) and/or beam reconfiguration confirmation information.

Therefore, the through link beam management method provided by the embodiment can timely and reasonably reconfigure the beam when the beam is required to be reconfigured, thereby further ensuring the service quality and improving the system performance on the basis of ensuring the service continuity.

Example three:

for convenience of understanding, in the following description, the selection of the beam direction, the reconfiguration and the recovery of the beam failure during the Sidelink unicast communication are taken as examples in the present embodiment.

Example one: SIDELink unicast communication beam direction selection

For V2X sidelink unicast communication, resource configuration between unicast communication UEs may be configured based on beam directions of related beams, and sidelink unicast communication may be considered in the beam direction with better measured beam quality. When the UE performs unicast communication in a direction of selecting one beam, because the UE is always in a relatively moving state, and after a period of time, the beam may have poor quality, it is necessary to perform beam failure recovery to select a new beam, and switch to the new beam to continue to perform sidelink unicast communication, thereby ensuring the continuity of the service.

Before V2X SideLink unicast communication, the UE may perform SideLink Discovery and SideLink communication connection establishment (which may also be referred to as PC5 connection establishment) on an initiative SL BWP (initiative SideLink Band Width Part, generally configured by a base station or preset configuration), determine a SideLink unicast communication beam direction in the SideLink Discovery or SideLink communication connection establishment process, and negotiate the SL BWP used for SideLink unicast communication between the UE pair in the SideLink communication connection establishment process. The Sidelink discovery includes, but is not limited to, model A and Model B discovery modes.

In the Model a sidelink discovery mode, after UE1 in fig. 1 is assumed to acquire sidelink discovery resources on an initial SL BWP, send sidelink discovery notification (i.e., direct link discovery announcement) messages in various directions through a beam scanning beam surfing mode; after monitoring the sidelink discovery notification message of the UE1, the UE2 in fig. 1 acquires the sidelink communication resource on the initial SL BWP, and then selects one or more good-quality beam directions to send the PC5 connection establishment request message in the beam directions of the sidelink discovery notification received from the UE 1. The UE1 selects the beam direction with the best beam quality or selects one beam direction from a plurality of beam qualities in the beam directions of the PC5 connection establishment request messages of the UE2, and sends a PC5 connection establishment response message, wherein the beam direction is used as the sidelink unicast communication beam direction between the UE1 and the UE 2. This process, as shown in fig. 6, includes:

s601: UE1 obtains sidelink discovery resources;

s602: UE1 sends sidelink discovery notification message to UE 2;

s603: UE2 acquires sidelink communication resources;

s604: UE2 selects one or more beam directions with good beam quality to send a PC5 connection establishment request message to UE 1;

s605: the UE1 selects the beam direction with the best beam quality or selects one beam direction from a plurality of beam qualities in the beam directions for monitoring the PC5 connection establishment request message of the UE2, and sends a PC5 connection establishment response message.

In the Model B sidelink discovery mode, after UE1 in fig. 1 acquires sidelink discovery resources on an initial SL BWP, it sends a sidelink discovery request (i.e., direct link discovery request) message in each direction or in one or more selected beam directions through a beam surfing mode. The UE2 selects the beam direction with the best beam quality or selects one beam direction from a plurality of beam directions with better beam quality from the beam directions for monitoring the sidelink discovery request message of the UE1, and sends the sidelink discovery response message, wherein the beam direction is used as the sidelink unicast communication beam direction between the UEs. And the UE1 receives the sidelink discovery response message of the UE2, after acquiring the sidelink communication resource, the UE1 and the UE2 carry out the PC5 connection establishment process in the selected beam direction, and then carry out sidelink unicast communication. This process, as shown in fig. 7, includes:

s701: UE1 and UE2 obtain sidelink discovery resources;

s702: UE1 sends a sidelink discovery solicitation message to UE 2;

s703: the UE2 selects the beam direction with the best beam quality or selects one beam direction from a plurality of beam directions with better beam quality from the beam directions monitoring the sidelink discovery request message of the UE1, and sends a sidelink discovery response message;

s704: UE1 and UR2 acquire communication resources;

s705: and the UE1 and the UE2 carry out PC5 connection establishment in the selected beam direction.

Example two: beam beam reconfiguration

In this example, the measurement of the direct link beam, sidelink beam, may also include, but is not limited to, at least one of: a sidelink synchronization reference signal, a sidelink discovery signal, a sidelink communication channel quality measurement signal, a newly defined signal special for sidelink beam measurement; the corresponding beam threshold values may include, but are not limited to: the receiving power threshold of the sidelink synchronization reference signal, the receiving power threshold of the sidelink discovery signal, the receiving power threshold of the sidelink communication channel quality measurement signal, and the newly defined signal receiving power threshold special for the sidelink beam measurement.

And (3) performing beam direction reconfiguration on Sidelink unicast communication:

when the UE detects that the quality of the beam (namely the beam currently used) of the current sidelink unicast communication is reduced and is lower than a configured/preconfigured beam quality threshold 1 (namely a first beam quality threshold), and or detects that the quality of other beams is better and is higher than a configured/preconfigured beam quality threshold 2 (namely a second beam quality threshold), the UE selects the beam with the best beam quality or selects one beam from the beams higher than the beam quality threshold 2 as a new beam direction of the sidelink unicast communication. The UE sends a reconfiguration message (including but not limited to a sidelink reconfiguration message and a beam reconfiguration message) to the opposite UE in the original beam direction, wherein the reconfiguration message comprises a new beam direction indication and a source UE identity. After receiving the new beam direction indication, the peer UE sends a reconfiguration response message (including, but not limited to, sidelink reconfiguration response/completion message and beam reconfiguration response/completion message) in the original beam direction or in the new beam direction, where the reconfiguration response message includes a target UE identity and/or beam reconfiguration confirmation information. After receiving the response confirmation information of the opposite-end UE, the UE switches/updates to the new beam to perform sidelink unicast communication, thereby realizing the reconfiguration of the wave beam, further ensuring the service quality on the basis of ensuring the service continuity and improving the system performance.

Example three: sidelink beam failure recovery configuration

In order to recover as soon as possible after failure occurs in the currently used beam, and avoid affecting the continuity of sidelink unicast communication service, the UE may negotiate about the sidelink beam failure recovery related configuration information, which includes at least one of the following: whether to synchronize source UE indication information, supported direct link sidelink discovery mode indication information, a beam failure detection resource (i.e. beam failure detection resource), a beam failure detection timer (i.e. beam failure detection timer), a maximum beam failure instance number (i.e. maximum beam failure instance number), a candidate beam resource (i.e. candidate beam resource), a beam failure recovery timer (i.e. beam failure recovery timer), a beam failure recovery request retransmission timer (i.e. beam failure recovery request retransmission timer), a beam failure recovery request retransmission maximum number (i.e. beam failure recovery request retransmission maximum number), a beam failure recovery maximum number (i.e. beam failure recovery maximum number), and a beam quality threshold (i.e. beam quality threshold); wherein, the candidate beam resource may include but is not limited to at least one of the following:

the beam index (i.e., beam index), the direct link synchronization reference signal (i.e., sidelink synchronization reference signal), the direct link discovery signal (i.e., sidelink discovery signal), the direct link communication channel measurement signal, the dedicated direct link beam measurement signal (i.e., signal dedicated to sidelink beam detection), the direct link synchronization resource (i.e., sidelink synchronization resource), the direct link communication resource (i.e., sidelink communication resource for sidelink communication usage), the direct link discovery resource (i.e., sidelink discovery resource), the beam failure recovery dedicated resource (i.e., beam failure recovery dedicated resource), and the beam failure recovery contention resource pool (i.e., beam failure recovery contention resource pool).

If the synchronization source UE is determined according to the indication information of the synchronization source UE, the UE can periodically send a sidelink synchronization reference signal, and the opposite end UE can directly measure the quality of the signal detection beam; if not, the beam quality can be detected by other methods.

When the UE acquires the Sidelink beam failure recovery configuration information from the peer UE, the information may be sent by, but not limited to, one of the following manners: PC5 connection establishment (request) message, PC5 connection establishment response message, PC5 bearer configuration response message, PC5 reconfiguration message, sidelink beam failure recovery configuration message, other PC5 signaling message.

Optionally, after receiving the sildelink beam failure recovery configuration information from the peer UE, the UE may also send a corresponding response or acknowledgement message to the peer UE. For example, an interactive process of the Sidelink beam failure recovery configuration information is shown in fig. 8, and includes:

s801: UE2 sends a Sidelink beam failure recovery configuration to UE 1;

s802: UE1 sends a Sidelink beam failure recovery config ack to UE 2.

Example four: sidelink beam failure recovery trigger

When a physical layer of a UE (here, a source UE) detects a sidelink beam failure (a specific detection method of a beam failure may be the beam quality detection method described above, or may also be other methods, such as a packet loss rate, etc.), indicating a SL beam failure event to the MAC, starting or restarting a beam failure detection timer for timing, and adding 1 to the number of SL beam failure event counted by the MAC; when the beam failure detection timer is overtime, the number of SL beam failure instances counted by the MAC is set to be 0; and when the number of times of the SL bean failure instance indication reaches the maximum number of times of the bean failure instance configured in the sidelink bean failure recovery configuration information, triggering a sidelink bean failure recovery process.

Example five: execution of Sidelink beam failure recovery

The first method is as follows:

the method for sending the SL beam failure recovery request message to the opposite-end UE (namely the target UE) by the UE through selecting the beam resource from the candidate beam resources comprises the following steps: UE identification information (destination layer 2 ID), or pair of negotiated pair of UE identification information, or other identification information that can be used for the peer to identify the UE. And if the opposite-end UE receives the request message, replying a response message by using the corresponding beam resource. When the UE receives the SL beam failure recovery response/ack message of the peer UE, which includes the peer UE identification information (destination layer 2 ID), or the pair negotiated pair identification information of the UE, or other identification information that can be used by the UE to identify the peer UE, the SL beam failure recovery is successful. This procedure aims to let the UE pair know the new beam direction. The schematic flow diagram of the SL beam failure recovery is shown in fig. 9:

s901: the UE1 and the UE2 carry out direct link unicast communication;

s902: UE1 detects a Sildelink beam failure recovery trigger;

s903: the UE1 sends a SL beam failure recovery request message to the UE2 by adopting the mode;

s904: UE4 sends SL beam failure recovery response/ack message to UE2 by adopting the mode;

s905: UE1 and UE2 switch to the new beam direction for communication.

Optionally, in the first mode, the selection of beam from the candidate beam resource includes, but is not limited to, the following two modes: 1) Selecting a beam with candidate beam quality higher than a configured threshold value (namely a preset optimal quality threshold value) according to a beam quality threshold configured in the Sidelink beam failure recovery configuration information, wherein if a plurality of candidate beams meet the condition, the UE can realize selection of one candidate beam; 2) And if the corresponding beam quality threshold is not configured in the Sidelink beam failure recovery configuration information, selecting the beam with the highest beam quality.

Optionally, in the first mode, if the UE does not receive the response message of the peer UE within a certain time (beam failure recovery request retransmission timer) after sending the SL beam failure recovery request message, retransmitting the BFR request, and if the maximum retransmission number (beam failure recovery request retransmission maximum number) is reached, the BFR fails; the UE then performs beam reselection to try the BFR again.

Optionally, in the first manner, if the UE does not receive the response message of the peer UE within a certain time (the beam failure recovery timer) after sending the SL beam failure recovery request message, the beam failure recovery fails this time; when the beam failure recovery fails, the UE selects other candidate beams meeting the conditions to try again to perform the beam failure recovery.

Optionally, in the first manner, if the number of times of reselecting the beam reaches the maximum number of times of beam failure recovery, or no beam resource satisfying the condition is selectable, it may be determined that the beam failure recovery fails (optionally, when the number of times of reselecting the beam is increased and the UE does not receive data sent by the UE at the opposite end within a period of time), the PC5 connection between the UEs may be disconnected or released;

the second method comprises the following steps:

a sidelink beam Failure Recovery was performed by SCI. The UE selects a beam resource among the candidate beam resources to send SCI, which may include but is not limited to at least one of the following: UE identity, BFR indication, new beam direction, no indication of corresponding data transmission. After receiving the SCI, the peer UE (i.e., the target UE) performs sidelink communication with the UE in the new beam direction.

In this approach, if the UE ID is layer 2 UE ID 24bit, including the source target UE ID 48bit, exceeds the original SCI size, so in some instances it may be considered to negotiate a small size ID that the UE pair can recognize (and not conflict with other UE/UE pairs) at PC5 connection setup or beam Failure Recovery configuration, or to extend the SCI.

In this embodiment, when the UE triggers the sidelink beam Failure Recovery process, it may also trigger sidelink Recovery message sending, and perform sidelink beam Failure Recovery through sidelink Recovery, for example, see the following third and fourth modes.

The third method comprises the following steps:

for the Model a simple discovery manner, the source UE sends a sidelink discovery and notification message using a beam turning manner, in order to distinguish other discovery messages sent for the beam failure recovery, the discovery message may include a beam recovery/switch/update identifier, and if the peer UE (i.e. the target UE, receives a discovery message on an omnidirectional or some signal-good beam) receives a discovery message sent by the UE, the peer UE informs a new beam direction through PC5 signaling, such as beam/recovery signaling, in one or more beam directions with better beam quality. After receiving the PC5beam switch/recovery signaling, the source UE selects a beam direction reply response message, and then the beam failure recovery is successful. And the two UEs use the new beam direction to carry out sidelink unicast communication.

The method is as follows:

for the Model B simple discovery mode, the source UE selects to send a discovery solicitation message in one or more beam directions, and may include a beam discovery/switch/update flag in the discovery message and wait for a discovery response message in order to distinguish other discovery messages that are not sent for beam failure recovery. The peer UE (i.e. the target) selects the beam direction with the best beam quality or selects one beam direction from a plurality of beam directions with better beam quality from the beam directions for monitoring the sidelink discovery request message of the UE, and sends the sidelink discovery response message. If the source UE receives the discovery response message of the peer UE in one of the beam directions, the beam failure recovery succeeds, the source UE performs sidelink communication for switching to the beam direction, and the peer UE also performs sidelink communication for switching to the beam direction.

Optionally, in this embodiment, the source UE and the target UE may send Model B discovery/response messages using candidate beam resources configured in the sidelink beam failure recovery, so that it is not necessary to wait for a discovery cycle, if a response is received, the beam failure recovery succeeds, and the UE communication pair may be switched to a new beam direction for sidelink communication, which may improve the efficiency of beam failure recovery.

Example four:

the present embodiment further provides an authorization verification control scheme for a UE, as shown in fig. 10, which includes:

s1001: and the base station acquires the UE authorization information.

In one example, the UE authorization information includes at least one of: direct link discovery authorization, direct link communication authorization, LTE direct link communication authorization, NR direct link unicast authorization, NR direct link broadcast/multicast authorization, the type of service supported by authorization, the role of service supported by authorization, the level of service automation supported by authorization.

In one example, the base station may perform authorization verification processing based on a resource request sent by the UE, and in this case, as shown in fig. 11, the method includes:

s1101: the base station obtains the UE authorization information, for example, the UE authorization information is obtained from an AMF (Access and Mobility management Function).

S1102: and the base station stores the acquired UE authorization information.

S1103: the base station receives a resource request sent by the UE.

S1104: and the base station performs authorization verification on the UE according to the stored UE authorization information.

In one example, the base station obtaining the UE authorization information may include, but is not limited to:

the base station obtains the UE authorization information from an AMF (Access and Mobility management Function) through the NG interface, for example, through but not limited to at least one of the following messages: a PDU (Protocol Data Unit, PDU) session resource establishment/modification request message, an initial context establishment request, a UE context modification request, a handover request;

the base station acquires UE authorization information from the adjacent base station through an Xn interface.

For example, in one example, after receiving a resource request sent by a UE, a base station may process the resource request according to authorization information in a UE context of the UE.

Optionally, the resource request sent by the UE includes a direct link communication resource request or a direct link discovery resource request; the base station processes the direct link communication/discovery resource request according to the authorization information in the UE context of the UE, and the processing comprises the following steps: and determining whether the UE can carry out direct link communication/discovery according to the authorization information, if so, configuring corresponding type resources for the UE.

Optionally, the resource request includes at least one of service role information and service automation level; the base station determines whether the UE supports the requested service according to the authorization information in the UE context of the UE, including but not limited to determining whether the UE is authorized to serve as its requested service role.

For example: for NR based V2X sidelink communication, if the base station has a relatively powerful function, for example, the gNB may schedule or configure LTE sidelink resources, when the UE requests a resource, the base station may verify, according to authorization information obtained in the context of the UE, whether the UE can perform LTE based V2X sidelink communication and/or NR based V2X sidelink communication, and then configure a corresponding type of resource for the UE; further, the UE may indicate which type (LTE V2X sidelink communication resources or NR V2X sidelink communication resources) of resources is requested when requesting resources.

For another example, UE capabilities and QoS required by different V2X service types are different (thereby affecting resource occupation, reservation, and scheduling policies), and when a UE needs to perform a certain V2X service, the base station verifies whether the UE authorizes to support the certain V2X service (e.g., a platform, an automatic driving, a remote driving, or a certain specific V2X service) according to the obtained authorization information in the context of the UE.
