Description

Method, device and system for transmitting scheduling request information

Technical Field

The present application relates to the field of communications, and in particular, to a method, an apparatus, and a system for transmitting a scheduling request.

Background

In a fifth generation (5 g) mobile communication system, a terminal device may send a Scheduling Request (SR) to a network device to request a Physical Uplink Shared Channel (PUSCH) resource.

Currently, a terminal device needs to bear an SR on a Physical Uplink Control Channel (PUCCH) resource for transmission, and the PUCCH resource for bearing the SR is a dedicated resource for the terminal device to transmit the SR, and usually, the dedicated resource cannot be occupied by other terminal devices or other information. However, in the unlicensed spectrum of the 5G system, since enough bandwidth needs to be occupied to meet the requirement of Occupying Channel Bandwidth (OCB), when transmitting uplink information, an interlace (interlace) structure needs to be adopted to occupy more Physical Resource Blocks (PRBs) in a frequency domain, and further, when transmitting SR information using SR dedicated resources, a plurality of PRBs need to be allocated despite of only 1 bit of information amount. Obviously, transmitting 1-bit information amount using multiple PRBs would cause a waste of resources.

Where in the description of the present application, "/" indicates a relationship where the objects associated before and after are an "or", unless otherwise stated, for example, a/B may indicate a or B; in the present application, "and/or" is only an association relationship describing an association object, and means that there may be three relationships, for example, a and/or B, and may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. Also, in the description of the present application, "a plurality" means two or more than two unless otherwise specified. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, at least one (one) of a, b, or c, may represent: a, b, c, a-b, a-c, b-c, or a-b-c, wherein a, b, c may be single or multiple. In addition, in order to facilitate clear description of technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish identical items or similar items with substantially identical functions and actions.

As shown in fig. 1, a communication system 10 is provided in an embodiment of the present application. The communication system 10 includes a network device 30, and a plurality of terminal devices 20 connected to the network device 30.

Accordingly, the terminal device 20 receives the identifier of the SR and the first information sent by the network device 30, and determines a target resource according to the first information, where the target resource is a resource capable of sending an SR transmission state corresponding to the identifier of the SR in the first resource, and the first resource is used for sending uplink control information and/or uplink data. The terminal device 20 sends the SR transmission status to the network device 30 on the target resource, and the network device 30 receives the SR transmission status sent by the terminal device 20 on the target resource. The specific implementation of the scheme will be described in detail in the following method embodiments, and will not be described herein again. Based on this scheme, since the terminal device 20 may determine, according to the first information sent by the network device 30, a target resource in the first resource for sending the uplink control information and/or the uplink data, and send an SR transmission state corresponding to the identifier of the SR on the target resource, resource waste may be reduced compared to a scheme in the prior art in which the terminal device 20 sends SR information on an SR-dedicated resource to the network device 30.

Or, taking the example that the network device 30 shown in fig. 1 interacts with any terminal device 20, in this embodiment, in a possible implementation manner, the network device 30 sends the identifier of the SR and the first information to the terminal device 20. Accordingly, the terminal device 20 receives the identifier of the SR and the first information sent by the network device 30, and determines a target resource according to the first information, where the target resource is a resource capable of sending the identifier of the SR in the first resource, and the first resource is used for sending uplink control information and/or uplink data. The terminal device 20 sends the identifier of the SR to the network device 30 on the target resource, and the network device 30 receives the identifier of the SR sent by the terminal device 20 on the target resource. The specific implementation of the scheme will be described in detail in the following method embodiments, and will not be described herein again. Based on this scheme, since the terminal device 20 may determine the target resource in the first resource for transmitting the uplink control information and/or the uplink data according to the first information transmitted by the network device 30, and transmit the identifier of the SR on the target resource, so that the network device may determine the SR requiring the resource according to the identifier of the SR, resource waste may be reduced compared to a scheme in the prior art in which the terminal device 20 transmits the SR information to the network device on the SR-dedicated resource to enable the network device to determine the SR requiring the resource according to the dedicated resource.

At present, in order to meet the requirement of the OCB, when SR information is transmitted using dedicated resources of the SR, a plurality of PRBs still need to be allocated, although the information amount is only 1 bit, and obviously, the use of a plurality of PRBs to transmit 1 bit of information amount causes waste of resources. Based on this, in the method, a terminal device receives an identifier of an SR and first information sent by a network device, and determines a target resource according to the first information, where the target resource is a resource capable of sending an SR transmission state corresponding to the identifier of the SR, and the first resource is used for sending uplink control information and/or uplink data. The terminal device sends the SR transmission state to the network device on the target resource, and then the network device receives the SR transmission state sent by the terminal device on the target resource. Based on the scheme, the terminal device may determine the target resource in the first resource for transmitting the uplink control information and/or the uplink data according to the first information transmitted by the network device, and transmit the SR transmission state corresponding to the identifier of the SR on the target resource, so that resource waste may be reduced compared to a scheme in the prior art in which the terminal device transmits the SR information to the network device on the SR-dedicated resource.

The following will describe, with reference to fig. 1 to fig. 3, a transmission method of SR information provided in the embodiment of the present application by taking an example of interaction between the network device 30 shown in fig. 1 and any terminal device 20.

It should be noted that, except for special descriptions, symbols in the following embodiments of the present application are all OFDM symbols, which are described herein in a unified manner, and the following embodiments are not described again.

In a possible implementation manner, as shown in fig. 4, a method for transmitting SR information provided in an embodiment of the present application includes the following steps:

s401, the network equipment sends the identifier of the SR and the first information to the terminal equipment. Correspondingly, the terminal device receives the identifier of the SR and the first information sent by the network device.

Optionally, the identifier of the SR is used to uniquely indicate the SR, and the identifier of the SR may be a Scheduling Request ID (Scheduling Request ID) or an SR resource identifier (SR resource ID).

S402, the terminal equipment determines the target resource according to the first information.

The target resource is a resource capable of sending an SR transmission state corresponding to the SR identifier in the first resource, and the first resource is used for sending uplink control information and/or uplink data.

The identifier of the SR is the identifier of the SR sent by the network device and received by the terminal device in step S401.

Optionally, in this embodiment of the present application, the content included in the first information is different, and the method for the terminal device to determine the target resource according to the first information is also different, including the following three cases:

in case one, the first information includes information of the target resource corresponding to the identity of the SR. Correspondingly, the terminal equipment determines the target resource according to the information of the target resource.

The first resource has different uses, and the target resource information is different, and correspondingly, the target resource determined by the terminal device according to the target resource information is different, including the following three scenarios:

(1) the first resource is used for sending uplink control information, the uplink control information is CSI, and the information of the target resource is an identifier related to the CSI.

The identifier related to the CSI may be a CSI reporting configuration identifier or a CSI reporting resource identifier.

Optionally, the first resource for sending CSI may be a CSI report resource, and the CSI report resource may be a PUCCH resource for transmitting periodic CSI or semi-static CSI; or may be a PUSCH resource for transmitting semi-static CSI.

Optionally, the identifier of the SR and the identifier related to the CSI may be in a one-to-one correspondence, that is, the SR transmission state corresponding to the identifier of the SR may only be sent on the CSI report resource corresponding to one CSI report configuration identifier.

For example, taking the identifier of the SR as an SR identifier 1 and the information of the target resource as a CSI report configuration identifier 1 as an example, the terminal device may determine, according to the correspondence between the SR identifier 1 and the CSI report configuration identifier 1, a transmission opportunity of an SR transmission state corresponding to the SR identifier 1, as shown in fig. 5a, a CSI report 1 corresponding to the CSI report configuration identifier 1 is transmitted in a time unit n +1 and a time unit n +4, and a CSI report 2 corresponding to the CSI report configuration identifier 2 is transmitted in a time unit n +3 and a time unit n + 6. Then, the terminal device may determine, according to the corresponding relationship between the SR identifier 1 and the CSI report configuration identifier 1, that the transmission opportunity of the SR transmission state corresponding to the SR identifier 1 is the transmission time unit of the CSI report 1 corresponding to the CSI report configuration identifier 1, that is, the time unit n +1 and the time unit n +4. And the terminal device determines a target resource according to the sending opportunity of the SR transmission state corresponding to the SR identifier 1, where the target resource may be one or more of a resource of the CSI report 1 corresponding to the time unit n +1 and a resource of the CSI report 1 corresponding to the time unit n +4.

The target resource is a CSI report resource corresponding to one time unit or CSI report resources corresponding to multiple time units, which may be determined according to actual conditions, including channel states, whether the terminal device needs to send data currently, and implementation of the terminal device. For example, the terminal device determines that a channel is idle at time t1, if at this time, the terminal device has data to be sent in one or more logical channels corresponding to the SR identifier 1 and needs to request resources from the network device, the terminal device may send the CSI report 1 and the SR transmission state corresponding to the SR identifier 1 on the resource of the CSI report 1 corresponding to the time unit n +1, and if before the time unit n +4, the terminal device receives the resource scheduled for the terminal device by the network device, the terminal device does not continue to send the SR transmission state corresponding to the SR identifier 1, and in this scenario, the target resource is the resource of the CSI report 1 corresponding to the time unit n + 1; or, if before time unit n +4, the terminal device does not receive the resource scheduled by the network device for the terminal device, and time unit n +4 is not within the transmission prohibition time corresponding to SR identifier 1, the terminal device may determine whether the channel is idle at the start time of time unit n +4, and if the channel is determined to be idle, the terminal device continues to send the SR transmission state corresponding to SR identifier 1 on the resource of CSI report 1 corresponding to time unit n +4, and in this scenario, the target resource is the resource of CSI report 1 corresponding to time unit n +1 and the resource of CSI report 1 corresponding to time unit n +4. It can be understood that, in practical applications, the terminal device may also determine, according to other situations, whether the target resource is a CSI report resource corresponding to one time unit or a CSI report resource corresponding to multiple time units, which is not specifically limited in this embodiment of the present application.

Optionally, the method for determining that the channel is idle by the terminal device may be Listen Before Talk (LBT), or may also be Clear Channel Assessment (CCA), or may also be channel monitoring (sending), which is not specifically limited in this embodiment of the present application.

Or, optionally, the corresponding relationship between the identifier of the SR and the identifier related to the CSI may also be one-to-many, that is, the SR transmission state corresponding to the identifier of the SR may be sent on the CSI report resources corresponding to the multiple CSI report configuration identifiers.

For example, taking the identifier of the SR as the SR identifier 1, and the information of the target resource as the CSI report configuration identifier 1 and the CSI report configuration identifier 3 as examples, the terminal device may determine the sending opportunity of the SR transmission state corresponding to the SR identifier 1 according to the corresponding relationship between the SR identifier 1 and the CSI report configuration identifier 1 and the corresponding relationship between the SR identifier 1 and the CSI report configuration identifier 3. As shown in fig. 5b, the CSI report 1 corresponding to the CSI report configuration identifier 1 is sent in time unit n +1 and time unit n +4, the CSI report 2 corresponding to the CSI report configuration identifier 2 is sent in time unit n +3 and time unit n +6, and the CSI report 3 corresponding to the CSI report configuration identifier 3 is sent in time unit n +2 and time unit n +5. The terminal device may determine, according to the corresponding relationship between the SR identifier 1 and the CSI report configuration identifier 1, and between the SR identifier 1 and the CSI report configuration identifier 3, that the transmission opportunity of the SR transmission state corresponding to the SR identifier 1 is a transmission time unit of the CSI report 1 corresponding to the CSI report configuration identifier 1 and a transmission time unit of the CSI report 3 corresponding to the CSI report configuration identifier 3, that is, a time unit n +1, a time unit n +4, a time unit n +2, and a time unit n +5. And the terminal device determines a target resource according to the sending opportunity of the SR transmission state corresponding to the SR identifier 1, where the target resource may be one or more of a resource of the CSI report 1 corresponding to the time unit n +1, a resource of the CSI report 1 corresponding to the time unit n +4, a resource of the CSI report 3 corresponding to the time unit n +2, and a resource of the CSI report 3 corresponding to the time unit n +5, where the target resource is a CSI report resource corresponding to one time unit or a CSI report resource corresponding to multiple time units, and the target resource may be determined according to actual conditions, including channel states, whether the terminal device needs to send data currently, and implementation of the terminal device, and the related description may refer to a description that the identifier of the SR and the identifier related to the CSI correspond to each other, and is not repeated herein.

It should be noted that the network device may also configure different identifiers of the SRs to correspond to the same identifier related to the CSI. For example, the network device may configure the CSI report configuration identifier 1 to correspond to the SR identifier 1 and the SR identifier 2, and the terminal device may determine, according to the correspondence, the SR transmission state corresponding to the SR identifier 1 and the transmission opportunity of the SR transmission state corresponding to the SR identifier 2. For example, as shown in fig. 5c, CSI report 1 corresponding to CSI report configuration identifier 1 is sent in time unit n +1 and time unit n +4, at this time, the terminal device may determine, according to the correspondence, that the sending opportunities of the SR transmission state corresponding to SR identifier 1 and the SR transmission state corresponding to SR identifier 2 are both the time unit sending CSI report 1 corresponding to CSI report configuration identifier 1, that is, time unit n +1 and time unit n +4. And the terminal equipment determines the resource for sending the SR transmission state corresponding to the SR identifier 1 and the resource for sending the SR transmission state corresponding to the SR identifier 2 according to the sending opportunity of the SR transmission state.

Optionally, in scenario (1) of the first case, the network device may carry the identifier of the SR and the identifier related to the CSI, which corresponds to the identifier of the SR, in the same high-level configuration information. For example, taking the identifier of the SR as the SR identifier and the identifier related to the CSI as the CSI report configuration identifier as an example, the network device may carry the SR identifier and the CSI report configuration identifier corresponding to the SR identifier in configuration information of the SR, and at this time, the configuration information of the SR may have a structure that:

SR identification (Scheduling Request ID);

an SR prohibit counter (SR prohibit timer);

SR transmission maximum number (SR trans Max);

CSI report configuration identification (CSI report configuration id).

When receiving the configuration information of the SR with the above structure, the terminal device may determine the CSI report configuration identifier corresponding to the identifier of the SR, and further may determine the target resource of the SR transmission state corresponding to the identifier of the SR.

Or, optionally, the network device may carry the identifier of the SR and the identifier related to the CSI corresponding to the identifier of the SR in different high-level configuration information, for example, taking the identifier of the SR as the SR identifier and the identifier related to the CSI as the CSI report configuration identifier, the network device may carry the SR identifier in the configuration information of the SR, and carry the corresponding relationship between the SR identifier and the CSI report configuration identifier in other high-level configuration information except the relevant configuration information of the SR and the relevant configuration information of the CSI.

(2) The first resource is used for sending uplink control information, the uplink control information is hybrid automatic repeat request (HARQ) information, and the information of the target resource is an HARQ process identifier.

Optionally, the corresponding relationship between the SR identifier and the HARQ process identifier may be in a one-to-one correspondence, that is, the SR transmission state corresponding to the SR identifier can only be sent on the resource corresponding to one HARQ process identifier.

For example, taking the SR identifier as SR identifier 1 and the information of the target resource as HARQ process identifier 1, the terminal device may determine the transmission opportunity of the SR transmission state corresponding to SR identifier 1 according to the corresponding relationship between SR identifier 1 and HARQ process identifier 1. Exemplarily, as shown in fig. 6a, the feedback of HARQ process 1 corresponding to HARQ process identity 1 is located at time unit n +4. The terminal device may determine that the transmission opportunity of the SR transmission state corresponding to the SR identifier 1 is located in time unit n +4 according to the corresponding relationship between the SR identifier 1 and the HARQ process identifier 1. And the terminal device determines a target resource according to the sending opportunity of the SR transmission state corresponding to the SR identifier 1, where the target resource may be a resource of the feedback HARQ process 1 corresponding to the time unit n +4.

Or, optionally, the corresponding relationship between the identifier of the SR and the identifier of the HARQ process may also be one-to-many, that is, the SR transmission state corresponding to the identifier of the SR may be sent on resources corresponding to multiple identifiers of the HARQ process.

For example, taking the SR identifier as SR identifier 1 and the information of the target resource as HARQ process identifier 1 and HARQ process identifier 2, the terminal device may determine the transmission opportunity of the SR transmission state corresponding to SR identifier 1 according to the corresponding relationship between SR identifier 1 and HARQ process identifier 1 and the corresponding relationship between SR identifier 1 and HARQ process identifier 2. Illustratively, as shown in fig. 6b, the feedback of HARQ process 1 corresponding to HARQ process id 1 is located at time unit n +4, and the feedback of HARQ process 2 corresponding to HARQ process id 2 is located at time unit n +5. The transmission opportunity of the SR transmission state corresponding to the SR identification 1 determined by the terminal device is located in time unit n +4 and time unit n +5. And the terminal device determines a target resource according to a transmission opportunity of an SR transmission state corresponding to the SR identifier 1, where the target resource may be one or more of a resource of the feedback HARQ process 1 corresponding to the time unit n +4 and a resource of the feedback HARQ process 2 corresponding to the time unit n +5, where the target resource is a resource of the feedback HARQ process corresponding to one time unit or a resource of the feedback HARQ processes corresponding to multiple time units, and the target resource may be determined according to an actual situation, including a channel state, whether the terminal device needs to transmit data currently, and implementation of the terminal device, and related description may refer to a description in which one of the identifier of the SR and the identifier related to the CSI corresponds to one another, which is not described herein again.

It should be noted that, the network device may also configure different SR identifiers to correspond to the same HARQ process identifier. For example, the network device may configure HARQ process identifier 1 corresponding to SR identifier 1 and SR identifier 2, and the terminal device may determine, according to the correspondence, an SR transmission state corresponding to SR identifier 1 and a transmission opportunity of an SR transmission state corresponding to SR identifier 2. For example, as shown in fig. 6c, the feedback of the HARQ process 1 corresponding to the HARQ process identifier 1 is located in a time unit n +4, and at this time, the terminal device may determine, according to the corresponding relationship, that the transmission opportunities of the SR transmission state corresponding to the SR identifier 1 and the SR transmission state corresponding to the SR identifier 2 are both time units n +4. And the terminal equipment determines the resource for sending the SR transmission state corresponding to the SR identifier 1 and the resource for sending the SR transmission state corresponding to the SR identifier 2 according to the sending opportunity of the SR transmission state.

Optionally, in scenario (2) of the first case, the network device may carry the identifier of the SR and the HARQ process identifier corresponding to the identifier of the SR in the same high-level configuration information. For example, taking the identifier of the SR as the SR identifier as an example, the network device may carry the SR identifier and the HARQ process identifier corresponding to the SR identifier in the configuration information of the SR, and at this time, the structure of the configuration information of the SR may be:

SR identification (Scheduling Request ID);

an SR inhibit counter (SR inhibit timer);

SR transmission maximum number (SR trans Max);

HARQ process identification (HARQ process ID).

When receiving the configuration information of the SR with the above structure, the terminal device may determine the HARQ process identifier corresponding to the identifier of the SR, and further may determine the target resource of the SR transmission state corresponding to the identifier of the SR.

Or, optionally, the network device may carry the identifier of the SR and the HARQ process identifier corresponding to the identifier of the SR in different high-level configuration information, for example, taking the identifier of the SR as the SR identifier, the network device may carry the SR identifier in the configuration information of the SR, and carry the corresponding relationship between the SR identifier and the HARQ process identifier in other high-level configuration information except the relevant configuration information of the SR.

(3) The first resource is used for sending uplink data, and the information of the target resource is an uplink transmission configuration identifier.

Optionally, the first resource for sending the uplink data may be a semi-persistent uplink resource configured by the network device for the terminal device. The network device may configure the semi-persistent uplink resource for the terminal device through configuration information, where the configuration information may include an uplink transmission configuration identifier, an identifier of the uplink resource, a period, and the like.

Optionally, the corresponding relationship between the SR identifier and the uplink transmission configuration identifier may be a one-to-one correspondence, that is, the SR transmission state corresponding to the SR identifier can only be sent on the uplink resource corresponding to one uplink transmission configuration identifier. And the terminal device determines a target resource according to the sending opportunity of the SR transmission state corresponding to the SR identifier, where the target resource may be an uplink resource corresponding to one or more time units. For the related description, reference may be made to the description in the scenario (1) in the first case, where the correspondence between the identifier of the SR and the identifier related to the CSI is one to one, and details are not repeated here.

Or, optionally, the corresponding relationship between the SR identifier and the uplink transmission configuration identifier may be one-to-many, that is, the SR transmission state corresponding to the SR identifier may be sent on the uplink resource corresponding to multiple uplink transmission configuration identifiers. The terminal device may determine, according to the correspondence, a transmission opportunity of the SR transmission state corresponding to the identifier of the SR. And the terminal device determines a target resource according to the sending opportunity of the SR transmission state corresponding to the SR identifier, where the target resource may be an uplink resource corresponding to one or more time units. For the related description, reference may be made to the description in the scenario (1) of the first case, where the corresponding relationship between the identifier of the SR and the identifier related to the CSI is one-to-many, and details are not repeated here.

It should be noted that the network device may also configure different SR identities to correspond to the same uplink transmission configuration identity, and the related description may refer to the description in the scenario (1) of the foregoing case i, where different SR identities correspond to the same CSI-related identity, which is not described herein again.

In case two, the first information includes an offset value of the SR and a period of the SR. In the second case, the first resource is used for transmitting uplink control information, and the uplink control information is CSI.

Accordingly, in the second case, the terminal device determines the target resource according to the offset value of the SR and the period of the SR.

The offset value of the SR is used to configure a transmission opportunity of the transmission state of the SR, that is, on which slot within the period of the SR the transmission state of the SR is transmitted.

Alternatively, the offset value of the SR may be determined by the network device according to the following formula (1):

wherein n is _f For the system frame number including the CSI transmission slot,

the number of time slots included in the system frame for different subcarrier spacing,

the frame number determined for the network equipment according to the relevant configuration of the CSI is n _f The system frame is configured with the time slot number, SR for sending CSI _offset,CSI Is an offset value of SR, SR _PERIODICITY Is the period of the SR.

Illustratively, as shown in fig. 7, the period of the SR configured by the network device is 2 slots, the system frame number including the CSI transmission slot is 0, and the subcarrier spacing is 15kHz, then

At 10, the transmission period of the CSI determined by the network device according to the relevant configuration of the CSI is 4 slots, and the transmission opportunity of the CSI is the

slot number

1,5,9 in the system frame 0, that is, the

slot number

1,5,9

Has a value of 1,5,9. Determining

After taking the value, the network device will take

Substituting the value 1 into the above formula (1) to obtain SR _offset,CSI Is 1, will

Substituting the value of 5 into the above formula (1) to obtain SR _offset,CSI Is 1,3,5, will

Substituting the value 9 into the above formula (1) to obtain SR _offset,CSI If the value of (1) is 1,3,5,7,9, the network device can take 1 as the SR _offset,CSI And taking the final value of (3), and applying the SR _offset,CSI And the final value of (2) and the period of the SR are sent to the terminal equipment.

After receiving the offset value of the SR and the SR period, the terminal device may determine a transmission opportunity of an SR transmission state corresponding to the configured SR identifier according to the following formula (2):

is numbered as n _f Of the system frame, SR _offset,CSI Is an offset value of SR _PERIODICITY Is the period of the SR.

Illustratively, as shown in FIG. 7 above, the terminal device will SR _offset,CSI Substituting the value 1 into the formula (2) determines that the configured transmission opportunity of the SR transmission state corresponding to the SR identifier is located in the time slot numbered 1,3,5,7,9 in the system frame 0. In addition, the terminal equipment alsoThe CSI may be determined to be sent in the time slots with

numbers

1,5, and 9 according to the relevant configuration of the CSI, where the actual sending opportunity of the SR transmission state corresponding to the SR identifier finally determined by the terminal device is the time slot in which the sending opportunity of the configured SR transmission state overlaps or is the same as the sending opportunity of the CSI, that is, the actual sending opportunity of the SR transmission state corresponding to the SR identifier is the time slot with

numbers

1,5, and 9, the target resource is the CSI report resource corresponding to the time slot 1, the CSI report resource corresponding to the time slot 5, and one or more of the CSI report resources corresponding to the time slot 9, where the target resource is the CSI report resource corresponding to one time slot or the CSI report resources corresponding to multiple time slots may be determined according to actual conditions, including a channel state, whether the terminal device needs to send data at present, and the implementation of the terminal device, and the relevant description may refer to a description that the identifier of the SR and the identifier related to the CSI, which is not described herein again.

Optionally, in this case two, the network device may carry the first information in the relevant configuration information of the SR. For example, taking the identifier of the SR as the SR identifier as an example, the network device may carry the first information in the configuration information of the SR, and at this time, the data structure of the configuration information of the SR may be:

SR identification (Scheduling Request ID);

an SR prohibit counter (SR prohibit timer);

SR transmission maximum number (SR trans Max);

a shift value of the SR offset (SR offset-CSI);

period of SR (SR period).

And thirdly, the first information is used for indicating the SR transmission state corresponding to the identifier that the terminal equipment can send the SR on the first resource.

Optionally, the first information may be newly defined Radio Resource Control (RRC) signaling. Illustratively, the RRC signaling may be "simultaneous-SR-CSI" for indicating a transmission state in which the terminal device is capable of transmitting the SR on the CSI report resource; alternatively, the RRC signaling may be "singular-SR-HARQ" for indicating a transmission state in which the terminal device is capable of transmitting an SR on the HARQ resource.

Correspondingly, in the third case, the determining, by the terminal device, the target resource according to the first information includes: and the terminal equipment determines the first resource in the first resources after the channel is idle as the target resource. The first resource is a resource with the smallest initial time unit in the first resource after the channel is idle, and if the initial time units of the plurality of resources are the same and the smallest, the first resource is a resource with the smallest serving cell identifier in the plurality of resources.

For example, as shown in fig. 8, taking uplink control information as CSI and taking the first resource as a CSI report resource as an example, the first resource determined by the terminal device according to the CSI-related configuration includes a CSI report resource corresponding to CSI report 1, a CSI report resource corresponding to CSI report 2, a CSI report resource corresponding to CSI report 3, and a CSI report resource corresponding to CSI report 4, and start time units of the CSI report resources corresponding to CSI report 2 and CSI report 4 are the same. If the terminal device determines that the channel is idle at the time t1, the resource with the minimum initial time unit in the first resource after the channel is idle includes a CSI report resource corresponding to the CSI report 2 and a CSI report resource corresponding to the CSI report 4. The identifier of the serving cell where the CSI report resource corresponding to the CSI report 2 is located is the smallest, so that a first resource (i.e., a target resource) in the first resources after the channel is idle is the CSI report resource corresponding to the CSI report 2. It should be noted that, here, the method for determining the target resource by the terminal device under the third condition is described only by taking the uplink control information as CSI as an example, it can be understood that, when the uplink control information is HARQ information, the terminal device may also determine the target resource by using a similar method, and details are not repeated herein.

Optionally, when the uplink control information is HARQ information, the first information may also be included in Downlink Control Information (DCI), and dynamically indicate whether the terminal device can transmit the SR transmission state in the HARQ resource scheduled by the DCI. For example, 1 bit is used in the DCI to indicate whether the SR transmission state can be transmitted in the HARQ resource scheduled by the DCI, a bit of "1" indicates that the SR transmission state can be transmitted in the HARQ resource, and a bit of "0" indicates that the SR transmission state cannot be transmitted in the HARQ resource.

Correspondingly, after the terminal device receives the DCI carrying the first information, and the first information indicates that the terminal device can transmit the SR transmission state on the resource scheduled by the DCI, the HARQ resource scheduled by the DCI carrying the first information may be determined as the target resource of the transmission state corresponding to the identifier for sending the SR.

For example, as shown in fig. 9, taking an example that a Physical Downlink Shared Channel (PDSCH) of 4 time units needs to be fed back on the same HARQ resource, the network device may carry first information in DCI of the last time unit, for example, use 1 bit to indicate whether an SR transmission state can be transmitted on the HARQ resource; or, to prevent the DCI of the last time unit from being lost, the network device may carry the same first information in the DCIs of the 4 time units, for example, respectively use 1 bit with the same value to indicate whether the SR transmission state can be transmitted on the HARQ resource. If the first information indicates that the terminal device is capable of transmitting the SR transmission state on the HARQ resource, the terminal device may determine the HARQ resource corresponding to the time unit n +5 indicated by the DCI as a target resource for transmitting the SR transmission state corresponding to the identifier of the SR.

In the three cases described above, except for case three, the network device does not explicitly indicate the transmission status that the terminal device is capable of transmitting the SR on the first resource in the remaining two cases. Based on this, optionally, in case one and case two, the method for transmitting SR information provided in the embodiment of the present application further includes: and the network equipment sends the second information to the terminal equipment. Correspondingly, the terminal device receives second information sent by the network device, where the second information is used to indicate that the terminal device is capable of sending the SR transmission state on the first resource. After receiving the second information, if it is necessary to send the SR transmission state corresponding to the identifier of the SR sent by the network device received in step S401, the terminal device determines the target resource according to the methods in the first and second cases.

Optionally, the second information may be newly defined radio resource control RRC signaling. Illustratively, the RRC signaling may be "simultaneous-SR-CSI" for indicating a transmission state in which the terminal device is capable of transmitting the SR on the CSI report resource; alternatively, the RRC signaling may be "singular-SR-HARQ" for indicating a transmission state in which the terminal device is capable of transmitting an SR on the HARQ resource.

S403, the terminal device sends the SR transmission state corresponding to the SR identification to the network device on the target resource. Correspondingly, the network device receives the SR transmission state corresponding to the SR identifier sent by the terminal device on the target resource.

Optionally, the SR transmission state corresponding to the SR identifier includes a first state or a second state, where the first state may be a "positive (positive)" state indicating a requested resource state, and the second state may be a "Negative (Negative)" state indicating an unsolicited resource state. Accordingly, the representation form of the SR transmission state corresponding to the identifier of the SR in the target resource may exist as follows:

in a form one, a first state of the SR transmission state is represented by a first demodulation reference signal (DMRS) modulated by a first target modulation symbol, and a second state of the SR transmission state is represented by a second DMRS modulated by a second target modulation symbol. The first target modulation symbol is a symbol obtained by modulating the first state by adopting a preset modulation mode, and the second target modulation symbol is a symbol obtained by modulating the second state by adopting the preset modulation mode.

Optionally, the DMRS may be a second DMRS carried on a target resource, or may be a DMRS determined by a terminal device according to a preset rule, which is not specifically limited in this embodiment of the present application.

Alternatively, the first expression may be determined as follows:

the terminal equipment firstly modulates the SR transmission state corresponding to the SR identifier by adopting a preset modulation mode to obtain a target modulation symbol, wherein the preset modulation mode can be Binary Phase Shift Keying (BPSK) or Pi/2BPSK. For example, taking the terminal device using the BPSK modulation scheme and using 1 bit to represent the SR transmission state as an example, as shown in table 1 below, a value of the 1 bit is "1" to represent a first state, and the terminal device modulates the 1 bit by using the BPSK modulation scheme to obtain a first target modulation symbol "-1"; or, the value of the 1 bit is "0" to indicate the second state, and the terminal device modulates the 1 bit by using a BPSK modulation method to obtain a second target modulation symbol "1".

TABLE 1

After the target modulation symbol is determined, the terminal equipment uses the first target modulation symbol to modulate one DMRS loaded on the target resource to obtain a first DMRS, or uses the second target modulation symbol to modulate the DMRS to obtain a second DMRS. For example, taking the DMRS as the sequence a (n) as an example, the DMRS modulated by the target modulation symbol may be denoted as "a (n) · target modulation symbol", and then the first DMRS may be denoted as-a (n), and the second DMRS may be denoted as a (n).

And in the second form, a first state of the SR transmission state corresponding to the SR identifier is represented by a first sequence cyclic shift value of the DRMS, and a second state of the SR transmission state is represented by a second sequence cyclic shift value of the DMRS.

Exemplarily, taking the terminal device to use 1 bit to represent the SR transmission state as an example, as shown in table 2 below, the 1 bit value being "1" represents a first state, and the first state is represented by a first sequence cyclic shift value "6" of the DMRS; or, the 1-bit value of "0" indicates a second state, and the second state is indicated by a second sequence cyclic shift value "0" of the DMRS.

TABLE 2

And in the third form, the SR transmission state corresponding to the identification of the SR is directly represented by 1 bit.

Optionally, the 1-bit value being "1" indicates a first state, and the 1-bit value being "0" indicates a second state. In the third form, the terminal device may send the SR transmission state to the network device on the target resource by:

the terminal device first calculates the number of Resource Elements (REs) that the 1-bit information needs to occupy, then determines a symbol in the target resource, and determines a part of REs from the REs corresponding to the symbol, where the number of the part of REs is the same as the number of REs that the SR transmission state needs to occupy, and finally discards the uplink control information or uplink data mapped on the part of REs, maps the 1-bit information representing the SR transmission state onto the part of REs, and sends the mapped uplink control information or uplink data to the network device. The symbol determined by the terminal device in the target resource may be a first symbol before or after a symbol carrying DMRS, or may also be a first symbol before or after a symbol reserved for carrying HARQ information.

For example, taking that the target resource includes 7 symbols, each symbol corresponds to 12 REs, and 1-bit information indicating the SR transmission state corresponding to the identifier of the SR occupies 2 REs, as shown in fig. 10a, one symbol determined by the terminal device in the target resource is a first symbol (symbol numbered 2) after a first DMRS carried by the target resource, and a part of REs determined from the REs corresponding to the symbol may be REs numbered 0 and 1 in the REs corresponding to the symbol. At this time, the terminal device may discard the uplink control information or uplink data mapped on RE0 and RE1 corresponding to symbol 2, and map 1-bit information indicating the SR transmission state corresponding to the identifier of the SR onto RE0 and RE1 corresponding to symbol 2.

Or, for example, taking that the target resource includes 7 symbols, each symbol corresponds to 12 REs, and 1-bit information indicating the SR identifies the corresponding SR transmission state occupies 2 REs, as shown in fig. 10b, one symbol determined by the terminal device in the target resource is a first symbol (symbol numbered 3) after a symbol used for carrying HARQ information, and a part of REs determined from the REs corresponding to the symbol may be REs numbered 0 and 1 in the REs corresponding to the symbol. At this time, the terminal device may discard the uplink control information or uplink data mapped on the RE0 and RE1 corresponding to the symbol 3, and map 1-bit information indicating the SR transmission status corresponding to the identifier of the SR onto the RE0 and RE1 corresponding to the symbol 3.

Optionally, in addition to sending, by the terminal device, the SR transmission state corresponding to the SR identifier to the network, in the second and third cases in step S402, the terminal device may also send, to the network device, the SR identifier, so that the network device determines the SR identifier corresponding to the SR transmission state transmitted on the target resource, that is, the network device determines which SR needs to request the resource or does not request the resource. Of course, the terminal device may also notify the network device of the SR identifier corresponding to the SR transmission state transmitted on the target resource in other manners, which is not specifically limited in this embodiment of the present application.

Based on the SR information transmission method provided in this embodiment of the present application, because the terminal device may determine, according to the first information sent by the network device, the target resource in the first resource used for sending the uplink control information and/or the uplink data, and send the SR transmission state corresponding to the identifier of the SR on the target resource, compared with a scheme in the prior art in which the terminal device sends the SR information on the SR-dedicated resource to the network device, resource waste may be reduced.

It should be noted that the method provided by the foregoing embodiment may be applied to a case where the network device does not configure the SR-specific resource for the terminal device, so as to reduce resource waste; or, the method can also be applied to a case that the network device configures the SR-dedicated resource for the terminal device, so as to increase the sending opportunity of the SR and reduce the transmission delay.

Exemplarily, as shown in fig. 11, the terminal device determines, at time t1, an SR transmission state corresponding to an identifier of an SR that needs to be transmitted, and a transmission opportunity of the SR transmission state corresponding to the identifier of the SR, which is configured for the terminal device by the network device, is a time unit n +2 between time t2 and time t3, but a channel is occupied during a time period from time t2 to time t3, so that the terminal device cannot transmit the SR transmission state on a dedicated resource of the SR. The subsequent terminal device determines that the channel is idle at time t4, at this time, the terminal device may determine the target resource from the first resource by using the method in step S402 (taking the target resource as the first resource corresponding to the time unit n +6 in fig. 11 as an example), and send the SR transmission state corresponding to the SR identifier that is not sent in time on the target resource, without waiting for a sending opportunity of the next SR transmission state configured by the network device, so that the sending opportunity of the SR may be increased, and the transmission delay may be reduced.

The processor 301 in the network device 30 shown in fig. 2 may call the application code stored in the memory 302 to instruct the network device to perform the actions of the network device in the above steps S401 to S403, and the processor 201 in the terminal device 20 shown in fig. 2 may call the application code stored in the memory 202 to instruct the network device to perform the actions of the terminal device in the above steps S401 to S403, which is not limited in this embodiment.

In another possible implementation manner, as shown in fig. 12, another SR information transmission method provided in this embodiment of the present application is provided, where the SR information transmission method includes the following steps:

s1201, the network equipment sends the identifier of the SR and the first information to the terminal equipment. Correspondingly, the terminal device receives the identifier of the SR and the first information sent by the network device.

Optionally, the identifier of the SR is used to uniquely indicate the SR, and the identifier of the SR may be a SR identifier (scheduling request ID) or an SR resource identifier (SR resource ID).

And S1202, the terminal equipment determines the target resource according to the first information.

The target resource is a resource capable of supporting sending the identifier of the SR in the first resource, and the first resource is used for sending uplink control information and/or uplink data.

The identifier of the SR is the identifier of the SR sent by the network device and received by the terminal device in step S1201.

Optionally, the uplink control information may be HARQ information or may also be CSI, and the relevant description may refer to step S402 described above, which is not described herein again.

The identifier related to CSI may be a CSI reporting configuration identifier or a CSI reporting resource identifier.

Optionally, the identifier of the SR and the identifier related to the CSI may correspond to each other one to one, that is, the SR transmission state corresponding to the identifier of the SR may only be sent on the CSI report resource corresponding to one CSI report configuration identifier; or, the correspondence between the identifier of the SR and the identifier related to the CSI may also be one-to-many, that is, the SR transmission state corresponding to the identifier of the SR may be sent on the CSI report resources corresponding to the multiple CSI report configuration identifiers; alternatively, the network device may configure different identities of the SRs to correspond to the same identity related to the CSI. The related description may refer to scenario (1) in the first case of step S402, which is not described herein again.

(2) The uplink control information is HARQ information, and the information of the target resource is HARQ process identification.

Optionally, the corresponding relationship between the SR identifier and the HARQ process identifier may be one-to-one, that is, the SR transmission state corresponding to the SR identifier can only be sent on the resource corresponding to one HARQ process identifier; or, the corresponding relationship between the SR identifier and the HARQ process identifier may also be one-to-many, that is, the SR transmission state corresponding to the SR identifier may be sent on the resource corresponding to the plurality of HARQ process identifiers; or, the network device may also configure different SR identities to correspond to the same HARQ process identity. The related description may refer to scenario (2) in the first case of step S402, which is not described herein again.

Optionally, the corresponding relationship between the SR identifier and the uplink transmission configuration identifier may be one-to-one, that is, the SR transmission state corresponding to the SR identifier can only be sent on the uplink resource corresponding to one uplink transmission configuration identifier; or, the corresponding relationship between the SR identifier and the uplink transmission configuration identifier may be one-to-many, that is, the SR transmission state corresponding to the SR identifier may be sent on the uplink resources corresponding to the multiple uplink transmission configuration identifiers; or, the network device may also configure different SR identifiers to correspond to the same uplink transmission configuration identifier. The related description may refer to scenario (3) in the first case of step S402, which is not described herein again.

Correspondingly, in the second case, the terminal device determines the target resource according to the offset value of the SR and the period of the SR.

Wherein, the offset value of the SR is used to configure the transmission opportunity of the identifier of the SR, i.e. on which slot within the period of the SR the identifier of the SR is transmitted. For the related description, reference may be made to the second case in step S402, which is not described herein again.

And in case III, the first information is used for indicating that the terminal equipment can send the identifier of the SR on the first resource.

Optionally, the first information may be newly defined RRC signaling; alternatively, when the uplink control information is HARQ information, the first information may be included in DCI, and dynamically indicate whether the terminal device can transmit the SR flag in the HARQ resource scheduled by the DCI.

Correspondingly, in the third case, the determining, by the terminal device, the target resource according to the first information includes: the terminal device determines the first resource in the first resources after the channel is idle as the target resource, where the relevant description may refer to the third case in step S402, which is not described herein again.

In the three cases described above, except for case three, the network device does not explicitly indicate in the remaining two cases that the terminal device is capable of transmitting the identification of the SR on the first resource. Based on this, optionally, in case one and case two, the method for transmitting SR information provided in the embodiment of the present application further includes: and the network equipment sends the second information to the terminal equipment. Correspondingly, the terminal device receives second information sent by the network device, where the second information is used to indicate that the terminal device is capable of sending the identifier of the SR on the first resource. After receiving the second information, if the terminal device needs to send the identifier of the SR sent by the network device received in step S1201, the terminal device determines the target resource according to the methods in the first case and the second case.

S1203, the terminal device sends the SR identifier to the network device on the target resource. Correspondingly, the network device receives the identifier of the SR sent by the terminal device on the target resource.

In a possible implementation manner, as long as the terminal device sends the identifier of the SR to the network device on the target resource, it indicates that the SR transmission state corresponding to the identifier of the SR is "positive", that is, the resource state needs to be requested.

In another possible implementation manner, the terminal device sends, in addition to the SR identifier, an SR transmission state corresponding to the SR identifier to the network device on the target resource, so as to explicitly indicate the SR transmission state corresponding to the SR identifier.

Optionally, when the terminal device further sends, to the network device, an SR transmission state corresponding to the SR identifier, where the SR transmission state includes a first state or a second state, the first state may be a "positive (positive)" state indicating a resource requesting state, and the second state may be a "Negative (Negative)" state indicating an unsolicited resource state. Accordingly, the representation form of the SR transmission state corresponding to the identifier of the SR in the target resource may exist as follows:

in the first form, a first state of the SR transmission state is expressed by a first DMRS modulated by a first target modulation symbol, and a second state of the SR transmission state is expressed by a second DMRS modulated by a second target modulation symbol. The first target modulation symbol is a symbol obtained by modulating the first state by adopting a preset modulation mode, and the second target modulation symbol is a symbol obtained by modulating the second state by adopting the preset modulation mode. For the related description, reference may be made to step S403, which is not repeated herein.

In a second form, a first state of the SR transmission state is represented by a first sequence cyclic shift value of the DRMS, and a second state of the SR transmission state is represented by a second sequence cyclic shift value of the DMRS. For the related description, reference may be made to step S403, which is not described herein again.

Optionally, the 1-bit value being "1" indicates a first state, and the 1-bit value being "0" indicates a second state. In the third form, the method for the terminal device to send the SR transmission state to the network device on the target resource may refer to the SR transmission state transmission method in the third form of step S403, and details are not repeated here.

Based on the SR information transmission method provided in the embodiment of the present application, because the terminal device can determine the target resource in the first resource for transmitting the uplink control information and/or the uplink data according to the first information transmitted by the network device, and transmit the identifier of the SR on the target resource, the network device can determine the SR requiring the resource according to the identifier of the SR, and therefore, compared with a scheme in the prior art in which the terminal device transmits the SR information to the network device on the SR-specific resource, the network device determines the SR requiring the resource according to the specific resource, resource waste can be reduced.

It should be noted that the method provided by the foregoing embodiment may be applied to a case where the network device does not configure the SR-specific resource for the terminal device, so as to reduce resource waste; or, the method can also be applied to a case that the network device configures the SR dedicated resource for the terminal device, so as to increase the SR transmission opportunity and reduce the transmission delay.
