Description

Configuration method, equipment and storage medium for side link configuration authorization

Technical field

The embodiments of the present application relate to communication technologies, and in particular, to a configuration method, device, and storage medium for sidelink configuration authorization.

Background technique

With the development of communication technology, the application of Vehicle-to-Everything (V2X) technology has become more and more widespread. V2X adopts a device-to-device (D2D) communication method, which is a communication method based on sidelink transmission technology (Sidelink, SL), so it has higher spectrum efficiency and lower transmission delay .

In the New Radio (NR) Internet of Vehicles, the following two resource allocation methods are supported. In one method, the terminal autonomously selects transmission resources in the resource pool for side-link transmission; in the other method, the network allocates side-link transmission resources to the terminal. Specifically, the network can use Dynamic Scheduling as The terminal allocates side link transmission resources; or the network may allocate side link configuration grant (CG) transmission resources for the terminal. For CG resource allocation methods, there are mainly two types: the first type of configuration authorization type-1CG and the second type of configuration authorization type-2CG.

For the manner in which the network allocates side link CG transmission resources to the terminal, the network includes at least the following parameters in the configuration signaling of the CG transmission resource for the terminal: time slot offset and period, and the terminal according to the time slot offset and period , To determine the time domain position of the CG transmission resource; where the time slot offset refers to the time slot of the first CG transmission resource relative to the system frame number (System Frame Number, SFN) cycle (or direct frame number (Direct Frame Number) , DFN) cycle) the number of time slots offset in the first time slot; cycle refers to the cycle of the side link configuration authorized transmission resource. In the above solution, the available CG transmission resources in different SFN cycles (or DFN cycles) correspond to different time domain positions. For example, in Figure 1, the resource pool contains 3033 time slots in one SFN cycle. If the time slot offset in the configuration parameters is 2 and the cycle is 4, then the available time slots of the CG transmission resource in the first SFN cycle They are

time slots

2, 6, 10,..., 3030, and the available time slots of CG transmission resources in the second SFN cycle are time slots 1, 5, 9,..., 3029, and so on. Therefore, if the configuration signaling is transmitted at least twice (including the first transmission and retransmission) when it crosses the SFN cycle boundary, the terminal does not know the slot offset parameter in the configuration signaling at this time is for the first SFN cycle. One time slot. Assuming that the network sends the configuration signaling in the first SFN cycle for the first time, but the terminal receives the retransmitted configuration signaling in the second SFN cycle, the terminal is not clear about the side link configuration authorization in the second SFN cycle The available time slots of the transmission resource are 1, 5, 9, ..., 3029, or 2, 6, 10, ..., 3030. Therefore, the available time slot of the configured authorized transmission resource determined by the terminal device may be inaccurate.

Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

The terms "first", "second", etc. in the description, claims, and the above-mentioned drawings of the embodiments of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific sequence or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein, for example. In addition, the terms "including" and "having" and any variations of them are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those clearly listed. Those steps or units may include other steps or units that are not clearly listed or are inherent to these processes, methods, products, or equipment.

At present, Vehicle-to-Everything (V2X) technology is more and more widely used. The device-to-device (D2D) communication method is adopted, which is a communication method based on sidelink transmission technology (Sidelink, SL), so it has higher spectrum efficiency and lower transmission delay.

In New Radio (NR) Internet of Vehicles (NR-V2X), the following two resource allocation methods are supported. In one method, the terminal autonomously selects transmission resources in the resource pool for side-link transmission; in the other method, the network allocates side-link transmission resources to the terminal. Specifically, the network can use Dynamic Scheduling as The terminal allocates side link transmission resources; or the network may allocate side link configuration grant (CG) transmission resources for the terminal. For CG resource allocation methods, there are mainly two types: the first type of configuration authorization type-1CG and the second type of configuration authorization type-2CG.

type-1CG: The network uses Radio Resource Control (RRC) signaling to configure side link transmission resources for the terminal. The RRC signaling configuration includes time domain resources, frequency domain resources, and demodulation reference signals (Demodulation Reference). Signal, DMRS), modulation and coding scheme (Modulation and coding scheme, MCS), including all transmission resources and transmission parameters. After receiving the high-level signaling, the terminal can immediately use the configured transmission parameters to perform sidelink transmission on the configured time-frequency resources.

type-2CG: adopts a two-step resource configuration method, that is, the RRC Downlink Control Information (DCI) method; first, the RRC signaling configuration includes the period of time-frequency resources, redundancy version, and the number of retransmissions , Hybrid Automatic Repeat reQuest (Hybrid Automatic Repeat reQuest, HARQ) transmission resources and transmission parameters including the number of processes, and then DCI activates type-2CG transmission, and configures time domain resources, frequency domain resources, MCS, etc. at the same time Include other transmission resources and transmission parameters. When the terminal receives RRC signaling, it cannot immediately use the resources and parameters configured by the higher-layer signaling for side-link transmission, but must wait for the corresponding DCI to be activated and configure other resources and transmission parameters before it can proceed. Link transmission.

Among them, the side link CG transmission resources allocated to the terminal by the network side are allocated from the resource pool, and the resource pool is a collection of resources that can be used for side transmission. In one embodiment, the network side can configure the terminal through configuration information Resource pool.

The following takes the SFN cycle as an example for description. One SFN cycle includes 10240 subframes, corresponding to

subframes

0, 1, 2,..., 10239; the synchronization subframes, downlink subframes, and special subframes are removed, and the remaining subframes are renumbered for

N _S-SSB represents the number of synchronization subframes, and N _dssf represents the number of downlink subframes and special subframes. If r satisfies the following conditions, the subframe l _r (0≤r<(10240-N _S-SSB -N _dssf )) belongs to the reserved subframe:

Among them, m=0,...,N _reserved -1, N _reserved =(10240-N _S-SSB -N _dssf )mod L _bitmap . L _bitmap represents the length of the bitmap used to indicate the time domain resources of the resource pool.

The terminal determines the resource pool as follows:

The total number of subframes included in one SFN cycle is 10240. The synchronization subframes, downlink subframes, special subframes and reserved subframes are removed, and the remaining subframes are renumbered as

The number of remaining subframes can be divisible _{by L bitmap, bitmap}

Repeated periodically in the remaining subframes, a bit of 1 indicates that the subframe corresponding to the bit in the remaining subframe belongs to the resource pool, otherwise it does not belong to the resource pool.

That is, the subframes belonging to the resource pool are

Among them, b _k' = 1, k'= k mod L _bitmap .

For a subcarrier interval of 15kHz, the number of subframes and time slots in one SFN cycle is the same. Therefore, the following embodiments take time slots as an example for description. In the following embodiments of this application, the subcarrier spacing is 15kHz. As an example, the situation is similar for other sub-carrier spacing.

In an embodiment, there are N _{RPs in an SFN cycle, and slot} time slots belong to the resource pool. The number of time slots in the resource pool can be determined by at least one of the following parameters: the total time included in an SFN cycle The number of slots, the number of time slots used for synchronization signals in an SFN cycle, the number of reserved time slots, the number of time slots that cannot be used for side-line transmission, the length of the bitmap, and the bitmap is taken The number of bits whose value is a specific value. Among them, the time slots that cannot be used for sideline transmission are, for example, downlink subframes or special subframes in the TDD system, or all downlink time slots configured by the network in the NR system.

For example, N _{RP, slot} is calculated by the following formula:

N _{RP, slot} = (N _slot -N _S-SSB -N _reserved )/L _bitmap ×N _bit-one

Among them: N _slot represents the total number of all time slots included in an SFN cycle, for example, N _slot = 10240 × 2 ^μ , μ = 0, 1, 2, 3, 4, and the corresponding subcarrier intervals are 15, 30, 60, 120 and 240kHz, N _S-SSB represents the number of time slots included in one SFN cycle for side-line synchronization signal block (S-SSB) transmission; N _reserved represents the number of time slots included in one SFN cycle The number of time slots is reserved. L _bitmap represents the length of the bitmap used to indicate the time domain resources of the resource pool; N _bit-one represents the number of bits in the bitmap with a value of 1 (a value of 1 indicates that the bit corresponds to The time slot belongs to the resource pool, and a value of 0 means that the time slot corresponding to the bit does not belong to the resource pool), or in other embodiments, it can also be the number of bits whose value is a preset value. This is not limited.

As shown in Figure 1, one SFN cycle includes 10240 time slots, the period of the synchronization signal is 160ms, and two synchronization time slots are included in one synchronization cycle. Therefore, there are 128 synchronization time slots in one SFN cycle. The length of the bitmap indicating the time domain resources of the resource pool is 10 bits, so 2 reserved time slots are required, and the number of remaining time slots is (10240-128-2=10110), which can be divisible by the length of the bitmap 10 , Renumber the remaining time slots as 0, 1, 2,..., 10109, the first 3 bits of the bitmap are 1, and the remaining 7 bits are 0, that is, in the remaining time slots, the first 3 of every 10 time slots One time slot belongs to the resource pool, and the remaining time slots do not belong to the resource pool. Since the bitmap needs to be repeated 1011 times in the remaining time slots to indicate whether all time slots belong to the resource pool, and each bitmap cycle includes 3 time slots, there are 3033 time slots in one SFN cycle. Belongs to the resource pool.

For the type-1CG resource allocation method, the network includes at least the following parameters in the CG transmission resource configuration signaling for the terminal: slot offset and period. According to the slot offset and period, determine the time of the CG transmission resource. Domain location; the time slot offset refers to the time slot of the first CG transmission resource relative to the system frame number (SFN) cycle (or the direct frame number (DFN) cycle). The number of time slots offset by a time slot; period refers to the period of the side link configuration authorized transmission resource. In the above solution, the available CG transmission resources in different SFN cycles correspond to different time domain positions. For example, in Figure 1, the resource pool contains 3033 time slots in one SFN cycle. If the time slot offset in the configuration parameters is 2 and the cycle is 4, then the available time slots of the CG transmission resource in the first SFN cycle They are

time slots

The technical solution of the present application will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

Fig. 2 is a schematic diagram of a communication system applied in an embodiment of this application. As shown in FIG. 2, the communication system includes at least a network device 11 and a terminal device 12. It can be understood that, in an actual communication system, there may be one or more network devices 11 and terminal devices 12. In FIG. 1, one network device is used as an example, and two terminal devices 12 are used as an example.

In FIG. 2, the network device 11 may be an access network device, for example, it may be an access device in an LTE network and its evolved network, such as an evolved base station (Evolutional Node B, eNB or eNodeB for short), or may also include 5G The next generation node B (gNB) in the NR system, or a relay station, or a base station in a new network system in the future, and so on.

The terminal device 12 may also be referred to as a mobile terminal, user equipment (User Equipment, UE for short), access terminal, user unit, user station, mobile station, mobile station, user terminal, terminal, wireless communication equipment, user agent or User device. Specifically, it can be smart phones, cellular phones, cordless phones, personal digital assistant (PDA) devices, handheld devices with wireless communication functions, or other processing devices connected to wireless modems, in-vehicle devices, wearable devices, etc. . In the embodiment of the present application, the terminal device has an interface for communicating with the network device.

The inventive concept of the method of the embodiment of the present application is as follows: the parameters of the configured authorized transmission resources determined by the network device can ensure that the available CG transmission resources in different SFN periods (or DFN periods) have the same time domain position, for example, in FIG. 3, The available time slots of CG transmission resources in SFN cycle 1 are

time slots

2, 5, 8, ..., 3032, and the available time slots of CG transmission resources in SFN cycle 2 are

time slots

2, 5, 8, ..., 3032, the available time slots in the following SFN cycle are also

time slots

2, 5, 8, ..., 3032.

Fig. 4 is an interaction flowchart of an embodiment of the configuration method provided by this application. As shown in Fig. 4, the specific implementation steps of this embodiment include:

Step 101: The network device sends a parameter for determining authorized CG transmission resources for the side link configuration, and the CG transmission resources have the same time domain position in different frame periods.

In an embodiment, the frame period is a system frame number SFN period or a direct frame number DFN period. In the following embodiment, the frame period is an SFN period as an example for description.

For example, in an SFN cycle, the time domain resources of CG transmission resources are time slots C1, C2, C3, and so on, where C1 is the time domain position of the first CG transmission resource in a resource pool in the SFN cycle , C2, C3, ... and other subsequent resources are determined according to the time domain resources of C1 and the period of the side link CG transmission resources. In different SFN cycles, the CG transmission resources are the transmission resources corresponding to the time slots C1, C2, C3, ... in the SFN cycle, that is, the time domain position of the CG transmission resource (the relative position of the real-time domain) in the different SFN cycle Are the same.

In order to satisfy that CG transmission resources have the same time domain position in different frame periods, in one embodiment, the parameter configured by the network device needs to meet the following preset condition: the time slot belonging to the first resource pool in one frame period The total number can be evenly divided by the period of the CG transmission resource.

The first resource pool is a collection of resources available for sideline transmission, and the CG transmission resource is a transmission resource belonging to the first resource pool.

In an embodiment, the preset condition may be embodied by the following formula (or other variations of the formula):

mod(N _{RP, slot} ,P) = 0

Among them: N _{RP, slot} represents the total number of time slots belonging to the first resource pool in a frame period, and mod() represents the remainder operation.

In an embodiment, the network side can configure a first resource pool for the terminal device through the configuration information, the transmission resources in the first resource pool can be used for the terminal device for side transmission, and the network side allocates the terminal device from the first resource pool Side link CG transmission resources.

Wherein, the N _{RP, slot} parameter can be determined according to at least one of the following parameters, at least one parameter includes: the total number of original time slots in the frame period, the total number of original time slots is 10240×2 ^μ , where the parameter μ is based on The sub-carrier interval is determined, μ = 0, 1, 2, 3, 4, corresponding to the sub-carrier interval being 15, 30, 60, 120 and 240kHz respectively; the number of time slots used to transmit synchronization signal blocks in the frame period; the frame period The number of reserved timeslots within; the number of timeslots that cannot be used for side-line transmission; the number of bits whose values are preset in the bitmap and the length of the bitmap. Wherein, the number of bits whose value is a preset value in the bitmap is, for example, the number of bits whose bit is 1 in the bitmap.

P represents the period of CG transmission resources, in units of time slots.

In an embodiment, the parameter for determining the CG transmission resource further includes: a slot offset N _offset , wherein, for any of the frame periods, the slot offset is used to determine the frame The time domain position of the _{first CG transmission resource belonging to the first resource pool in the period, N offset} represents the time of the first CG transmission resource relative to the first time slot belonging to the first resource pool in the frame period The slot offset is used to determine the slot position of the first CG transmission resource in each frame period.

In an embodiment, _{the value range of the slot offset N offset} is [0, P-1]. The slot offset can be expressed by the number of slots.

In an embodiment, as shown in FIG. 3, if the parameter N _offset of the CG transmission resource configured by the network is 2, it means that the time slot of the first CG transmission resource is relative to the first one in the first resource pool in the frame period. The offset of the time slot is 2 time slots, that is, the time slot of the first CG transmission resource is the second time slot belonging to the first resource pool in the frame period (the time slot number starts from 0), and the time slot of the CG transmission resource Period P=3.

According to the above parameter configuration, in one SFN cycle, the side link CG transmission resources correspond to the

time slots

2, 5, 8, 11,..., 3032 in the first resource pool respectively; further, since the above presets are satisfied Conditions, therefore, in different SFN cycles, the time domain position of the side link CG transmission resources is the same.

In the foregoing embodiment, the parameters used to determine the CG transmission resources (such as the period of the CG transmission resources) and the parameters of the resource pool time domain resources (such as the total number of time slots belonging to the first resource pool in the frame period) need to satisfy The specific relationship of CG transmission resources in different frame periods makes the time domain resources of the CG transmission resources the same.

Step 102: The terminal device determines the CG transmission resource according to the parameter.

The terminal device receives the above-mentioned parameter used to determine the CG transmission resource sent by the network device, determines the available CG transmission resource according to the parameter, and uses the CG transmission resource to transmit data.

In the method of this embodiment, the network device sends a parameter for determining authorized CG transmission resources for the side link configuration, and the CG transmission resource determined by the terminal device according to the parameter has the same time domain position in different frame periods, so the terminal device No matter in which frame period the parameter sent by the network device is received, the time domain position of the CG transmission resource can be accurately determined.

In an embodiment, the method further includes:

The network device sends first configuration information, where the first configuration information is used to determine at least one second resource pool, and the at least one second resource pool includes the first resource pool; the CG transmission resource is a transmission resource belonging to the first resource pool.

In an embodiment, the first configuration information may be radio resource control RRC signaling or a system information block (System Information Block, SIB).

Specifically, the first resource pool may be determined by the first configuration information sent by the network device, and the CG transmission resource is a transmission resource in the first resource pool.

The first configuration information may configure at least one second resource pool, the at least one second resource pool includes the first resource pool, and the first configuration information is, for example, used to indicate information about resources included in the second resource pool.

In an embodiment, step 101 can be implemented in the following manner:

The network device sends second configuration information, where the second configuration information includes the parameter used to determine the CG transmission resource.

In an embodiment, the second configuration information is radio resource control RRC signaling or downlink control information DCI signaling.

The first configuration information and the second configuration information may be the same configuration information or different configuration information, which is not limited in the embodiment of the present application.

In an embodiment, for type-1CG, the network device may send the above-mentioned parameters for determining the CG transmission resource through the second configuration information, for example, including the parameter of the CG transmission resource and the time slot offset.

For example, if the period of the CG transmission resource configured by the network is 3 time slots and the time slot offset is 2 time slots, then the time slots that can be used for sideline transmission in the first resource pool determined by the terminal device are { 2 , 5, 8, 11,..., 3032}.

In an embodiment, for type-2CG, the network device sends the cycle of CG transmission resources through RRC signaling (or other high-level signaling), and the network sends DCI to determine the first resource pool belonging to the first resource pool in the frame period. The time domain position of the CG transmission resource, for example, the time slot in which the DCI is received is the time domain position of the first CG transmission resource. For example, if the period of the CG transmission resource configured by the network is 3 time slots, and the time slot in which the DCI is received is time slot 7 in the current frame period, the terminal device determines the available resources belonging to the first resource pool in the current frame period. The time slots for side-line transmission are {7, 10, 13, 17, ..., 3031}, and the time slots that belong to the first resource pool in the subsequent frame periods and can be used for side-line transmission are {1, 4 , 7, 10, 13, 17, ..., 3031}.

In another embodiment, for type-2CG, the network device sends the cycle of CG transmission resources through RRC signaling (or other high-level signaling), and the network sends DCI to determine the first resource pool belonging to the first resource pool in the frame period. The time domain position of each CG transmission resource, such as the time slot offset indicated by DCI, is used to indicate the time slot of the first CG transmission resource belonging to the first resource pool in the frame period, relative to the time slot that received the DCI The number of time slots offset by the time slot. The terminal device determines the position of the first CG transmission resource time slot by receiving the time slot of the DCI and the time slot offset. For example, if the period of the CG transmission resource configured by the network is 3 time slots, the time slot that receives the DCI is time slot 7 in the current frame period, and the time slot offset is 2, then the terminal device determines the current frame period in the The first CG transmission resource is time slot 9. The frame period belongs to the first resource pool and the time slots available for side-line transmission are {9, 12, 15, 18,..., 3030}, for other subsequent frames The time slots that belong to the first resource pool in the cycle and can be used for side-line transmission are {0, 3, 6, 9, 12, 15, 18, ..., 3030}.

In an embodiment, for the case where the side-line transmission and the uplink transmission share a carrier, the side-line transmission can only use uplink time slots or uplink symbol resources. At this time, the total number of original time slots in the frame period, N _slot, represents a frame The number of uplink time slots available for sideline transmission in a cycle.

Further, it can include the following specific implementation methods:

In one case, when all the symbols in the uplink time slot are uplink symbols, it can be used for side-line transmission;

In another case, when part of the symbols in the uplink time slot are uplink symbols, it can also be used for side-line transmission. Further, the number of uplink symbols in an uplink time slot is greater than a preset value, and the preset value is, for example, a preset value configured by the network, such as 7, and only when the number of uplink symbols in an uplink time slot is greater than or equal to At 7 o'clock, the uplink time slot is a time slot that can be used for side-line transmission, otherwise it is an unusable time slot.

In other embodiments, the preset value may be predefined or determined in other ways, which is not limited in this application.
