[0026] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0027] The network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. A person skilled in the art will appreciate that, with the evolution of the network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems.

[0028] Please refer to Figure 1, which shows a schematic diagram of a network architecture provided by an embodiment of the present application. The network architecture may include: a core network 11, an access network 12, and a terminal device 13.

[0029] The core network 11 includes several core network devices. The functions of the core network devices are mainly to provide user connections, user management, and service carrying, and to provide an interface to the external network as a bearer network. For example, the core network of a 5G (5th Generation) NR (New Radio) system may include devices such as an AMF (Access and Mobility Management Function) entity, a UPF (User Plane Function) entity, and an SMF (Session Management Function) entity.

[0030] The access network 12 includes several access network devices 14. The access network in the 5G NR system can be called NG-RAN (New Generation-Radio Access Network). The access network device 14 is a device deployed in the access network 12 to provide wireless communication functions for the terminal device 13. The access network device 14 may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different wireless access technologies, the names of devices with access network device functions may be different. For example, in the 5G NR system, they are called gNodeB or gNB. With the evolution of communication technology, the name of "access network device" may change. For the convenience of description, in the embodiments of the present application, the above-mentioned devices that provide wireless communication functions for the terminal device 13 are collectively referred to as access network devices.

[0031] The number of terminal devices 13 is usually multiple, and one or more terminal devices 13 can be distributed in the cell managed by each access network device 14. The terminal device 13 may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, as well as various forms of user equipment, mobile stations (MS), etc. For the convenience of description, the devices mentioned above are collectively referred to as terminal devices. The access network device 14 and the core network device communicate with each other through some air technology, such as the NG interface in the 5G NR system. The access network device 14 and the terminal device 13 communicate with each other through some air technology, such as the Uu interface. In the embodiments of the present application, the terminal device and UE (User Equipment) express the same meaning, and the two are often used interchangeably, but those skilled in the art can understand their meaning.

[0032] Terminal devices 13 and terminal devices 13 (for example, vehicle-mounted devices and other devices (such as other vehicle-mounted devices, mobile phones, RSU (Road Side Unit, road test unit), etc.)) can communicate with each other through a direct communication interface (such as a PC5 interface). Accordingly, the communication link established based on the direct communication interface can be called a direct link or SL. SL transmission is the direct communication and data transmission between terminal devices through a side link. Unlike traditional cellular systems where communication data is received or sent through access network equipment, SL transmission has the characteristics of short delay and low overhead, and is suitable for communication between two terminal devices that are geographically close (such as vehicle-mounted devices and other peripheral devices that are geographically close). It should be noted that in Figure 1, only vehicle-to-vehicle communication in the V2X (vehicle to everything) scenario is used as an example. SL technology can be applied to scenarios where direct communication is carried out between various terminal devices. In other words, the terminal device in this application refers to any device that communicates using SL technology.

[0033] The "5G NR system" in the embodiments of this application may also be referred to as a 5G system or an NR system, but those skilled in the art will understand its meaning. The technical solutions described in the embodiments of this application can be applied to the 5G NR system and can also be applied to subsequent evolution systems of the 5G NR system.

[0034] Before introducing the technical solutions of this application, we first introduce and explain some of the background technologies involved in this application. The following related technologies can be combined with the technical solutions of the embodiments of this application as optional solutions, and they all fall within the scope of protection of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0035] 1.SL transmission

[0036] Regarding SL transmission, 3GPP defines two transmission modes: Mode A and Mode B.

[0037] Mode A: The transmission resources of the terminal device are allocated by the access network device (such as a base station). The terminal device transmits communication data on the side link according to the transmission resources allocated by the access network device. The access network device can allocate transmission resources for a single transmission to the terminal device, or allocate transmission resources for a semi-static transmission to the terminal device.

[0038] Mode B: The terminal device selects a transmission resource from the resource pool to transmit communication data. Specifically, the terminal device can select a transmission resource from the resource pool by listening or by random selection.

[0039] The following mainly introduces the method of SL communication in the NR V2X system and the terminal device's autonomous resource selection (that is, the above-mentioned mode B).

[0040] 2.NR V2X physical layer structure

[0041] The physical layer structure of SL communication in the NR V2X system is shown in Figure 2. The first symbol in the time slot shown in Figure 2 is an AGC (Automatic Gain Control) symbol. When the SL UE receives, the received power can be adjusted in this symbol to a power suitable for demodulation. When the SL UE transmits, the content of the symbol following the AGC symbol is repeated on the AGC symbol. In Figure 2, the PSCCH (Physical Sidelink Control Channel) is used to carry the first sidelink control information, and the PSSCH (Physical Sidelink Shared Channel) is used to carry data and the second sidelink control information. The PSCCH and PSSCH are transmitted in the same time slot. The first sidelink control information and the second sidelink control information can be two sidelink control information with different functions. For example, the first sidelink control information is carried in the PSCCH and mainly contains fields related to resource sensing, which facilitates resource exclusion and resource selection after decoding by other terminal devices. In addition to data, the PSSCH also carries secondary sidelink control information, primarily including fields related to data demodulation, to facilitate demodulation of the data in the PSSCH by other terminal devices. Within a given time slot, symbols corresponding to the PSFCH may also exist. The PSFCH is used to transmit HARQ feedback information. Depending on the resource pool configuration, PSFCH symbols may appear once every 1, 2, or 4 time slots. When no PSFCH symbols exist in a time slot, for example, the GAP symbol between the PSSCH and PSFCH in Figure 2, the AGC used for PSFCH reception, and the PSFCH symbols are all used to carry the PSSCH. Typically, the last symbol in a time slot is the GP (Guard Period) symbol, or GAP. In other words, the symbol following the last PSSCH or PSFCH symbol is a GP symbol. SL UEs perform transceiver switching within GP symbols and do not transmit. When PSFCH resources exist in a time slot, GP symbols also exist between the PSSCH and PSFCH symbols. This is because the UE may transmit on PSSCH and receive on PSFCH, and GP symbols are also needed for transmission and reception conversion.

[0042] 3. Resource reservation in NR V2X

[0043] In the NR V2X system, in Mode B, the terminal device independently selects transmission resources to send data. Resource reservation is a prerequisite for resource selection.

[0044] Resource reservation refers to the terminal sending the first sidelink control information in the PSCCH to reserve resources for subsequent use. In the NR V2X system, resource reservation within a TB (Transport Block) is supported, as well as resource reservation between TBs.

[0045] As shown in Figure 3, the terminal device sends the first side control information, and uses the "Time resource assignment" and "Frequency resource assignment" fields to indicate the N time-frequency resources of the current TB (including the resources used for the current transmission). Wherein N≤Nmax, in NR V2X, Nmax is equal to 2 or 3. At the same time, the above-mentioned N indicated time-frequency resources should be distributed in W time slots. In NR V2X, W is equal to 32. For example, in TB1 shown in Figure 3, the terminal device sends the first side control information in the PSCCH while sending the initial transmission data in the PSSCH, and uses the above two fields to indicate the time-frequency resource positions of the initial transmission and retransmission 1 (that is, N=2 at this time), that is, the time-frequency resources for retransmission 1 are reserved. In addition, the initial transmission and retransmission 1 are distributed in 32 time slots in the time domain. Similarly, in TB1 shown in FIG3 , the terminal device uses the first sidelink control information sent in the PSCCH of retransmission 1 to indicate the time-frequency resource positions of retransmission 1 and retransmission 2, and retransmission 1 and retransmission 2 are distributed in 32 time slots in the time domain.

[0046] At the same time, when the terminal device sends the first sidelink control information, it uses the "Resource reservation period" field to reserve resources between TBs. For example, in Figure 3, when the terminal device sends the first sidelink control information for the initial transmission of TB1, it uses the "Time resource assignment" and "Frequency resource assignment" fields to indicate the time-frequency resource locations for the initial transmission and retransmission 1 of TB1, which are recorded as {(t1, f1), (t2, f2)}. Among them, t1 and t2 represent the time domain locations of the resources for the initial transmission and retransmission 1 of TB1, and f1 and f2 represent the corresponding frequency domain locations. If the value of the "Resource reservation period" field in the first sidelink control information is 100 milliseconds, then the SCI (Sidelink Control Information) also indicates the time-frequency resources {(t1+100, f1), (t2+100, f2)}, and these two resources are used for the transmission of the initial transmission and retransmission 1 of TB2. Similarly, the first side control information sent in TB1 retransmission 1 also reserves the time-frequency resources for TB2 retransmission 1 and retransmission 2 using the "Resource reservation period" field. In NR V2X, the possible values ​​of the "Resource reservation period" field are 0, 1-99, 100, 200, 300, 400, 500, 600, 700, 800, 900, and 1000 milliseconds, which is more flexible than LTE (Long Term Evaluation) V2X. However, in each resource pool, only e of the values ​​are configured, and the terminal device determines the possible values ​​to be used based on the resource pool used. The e values ​​in the resource pool configuration are recorded as the resource reservation period set M. For example, e is less than or equal to 16.

[0047] In addition, through network configuration or pre-configuration, the above-mentioned reservation between TBs can be activated or deactivated in units of resource pools. When activating the reservation between TBs, the first side control information includes the "Resource reservation period" field. When deactivating the reservation between TBs, the first side control information does not include the "Resource reservation period" field. When activating the reservation between TBs, generally, before triggering resource reselection, the value of the "Resource reservation period" field used by the terminal device, that is, the resource reservation period, will not change. Each time the terminal device sends the first side control information, it uses the "Resource reservation period" field therein to reserve resources for the next period for the transmission of another TB, thereby achieving periodic semi-continuous transmission.

[0048] When a terminal device operates in the aforementioned mode B, it can obtain the first sidelink control information sent by other terminal devices by monitoring the PSCCH sent by other terminal devices, thereby learning the resources reserved by other terminal devices. When selecting resources, the terminal device will exclude the resources reserved by other terminal devices to avoid resource collision.

[0049] 4. Resource Selection Method for NR V2X Interception

[0050] In the NR V2X system, in the above-mentioned mode B, the terminal device needs to select resources on its own.

[0051] As shown in Figure 4, the terminal device triggers resource selection or reselection in time slot n or time slot n is the time slot where the higher layer triggers the physical layer to report the candidate resource set. The resource selection window 10 starts from n+T1 and ends at n+T2. 0<=T1<=T proc,1 , when the subcarrier spacing is 15, 30, 60, 120kHz, T proc,1 The time slots are 3, 5, 9, and 17. 2min <=T2<=remaining delay budget of the service, T 2min The value set is {1,5,10,20}*2 μ time slots, where μ = 0, 1, 2, 3 corresponds to the case where the subcarrier spacing is 15, 30, 60, 120 kHz. The terminal device determines T from the value set according to the priority of its own data to be sent. 2min For example, when the subcarrier spacing is 15kHz, the terminal device determines T from the set {1, 5, 10, 20} according to the priority of its own data to be sent. 2min When T 2minIf T2 is greater than or equal to the service's remaining delay budget, then T2 equals the service's remaining delay budget. The remaining delay budget is the difference between the time at which the data's delay requirement corresponds and the current time. For example, if a data packet arrives at time slot n and the delay requirement is 50 milliseconds, and a time slot is 1 millisecond, then if the current time is time slot n, the remaining delay budget is 50 milliseconds. If the current time is time slot n+20, the remaining delay budget is 30 milliseconds.

[0052] Terminal equipment is in n-T0 to nT proc,0 Perform resource monitoring (excluding nT proc,0 ), T0 is 100 or 1100 milliseconds. When the subcarrier spacing is 15, 30, 60, or 120 kHz, T proc,0 The time slots are 1, 1, 2, and 4. Optionally, the terminal device performs resource listening in the time slots of the resource pool used by it within the resource listening window. Optionally, the terminal device listens to the first sideline control information sent by other terminal devices in each time slot (except its own sending time slot). When the time slot n triggers resource selection or reselection, the terminal device uses n-T0 to nT proc,0 The result of resource listening.

[0053] Step 1: The terminal device takes all available resources in the resource pool used by the terminal device within the resource selection window 10 as resource set A. Any resource in set A is denoted as R(x,y), where x and y indicate the frequency domain position and time domain position of the resource respectively. The initial number of resources in set A is denoted as M. total The terminal device excludes resources from resource set A based on the un-listened time slots within the resource listening window 20 (Step 1-1) and / or the resource listening results within the resource listening window 20 (Step 1-2). The terminal device determines whether resource R(x,y) or a series of periodic resources corresponding to resource R(x,y) overlaps with the time slot determined based on the un-listened time slots in Step 1-1 or the resource determined based on the detected first sidelink control information in Step 1-2. If so, resource R(x,y) is excluded from resource set A.

[0054] Step 1-1: If the terminal device is in time slot t within the resource listening window 20 m Send data, no listening, the terminal device will be based on the time slot t m For each allowed resource reservation period in the resource pool used by the terminal device, the corresponding Q time slots are determined with the resource reservation period as the interval. If the Q time slots overlap with the resource R(x,y) or a series of periodic resources corresponding to the resource R(x,y), the resource R(x,y) is excluded from the resource set A. (Represents rounding up). Tscal is equal to the value of T2 converted to milliseconds. Prx is one of the resource reservation periods allowed by the resource pool used by the terminal device. Optionally, a series of periodic resources corresponding to the resource R(x,y) is R(x,y+j*Ptxlg), j=0,1,2,…,Cresel-1. Cresel is related to the random count value generated by the terminal device, and Ptxlg is the number after Ptx is converted into logical time slots. Ptx is the resource reservation period of the terminal device. For example, in sub-figure (a) of Figure 4, Cresel is 3, indicating 3 periodic resources corresponding to the resource R(x,y) (including R(x,y)).

[0055] For example, in sub-graph (a) of Figure 4, the terminal device is in time slot t m Without listening, resources are excluded according to each resource reservation period in the resource reservation period set M in the resource pool configuration. For a resource reservation period 1, assuming that the Q value is calculated to be 2, the corresponding Q time slots are the time slots from time slot t in sub-graph (a) of Figure 4. m The next two time slots marked with horizontal lines are mapped with the resource reservation period 1 as the interval. For a resource reservation period 2, assuming that the Q value is calculated as Q=1, the corresponding Q time slots are the time slots from time slot t in Figure 4 (a). m The next time slot marked with dotted shadows and with resource reservation period 2 as the interval is mapped.

[0056] The terminal device will determine whether the Q time slots corresponding to each reservation period overlap with the resource R(x,y) or a series of periodic resources corresponding to the resource R(x,y). If so, the resource R(x,y) will be excluded from the resource set A.

[0057] Optionally, when the resource pool used by the terminal device deactivates the reservation between TBs, the terminal device may not execute the above Step 1-1.

[0058] Optionally, after executing Step 1-1, if the remaining resources in resource set A are less than M total *X, then the resource set A is initialized to all available resources in the resource selection window 10 belonging to the resource pool used by the terminal device and then Step 1-2 is executed.

[0059] Step 1-2: If the terminal device is in the time slot t of the resource listening window 20 mThe first sidelink control information transmitted in the PSCCH is detected, and the SL-RSRP (Sidelink Reference Signal Received Power) of the PSCCH or the SL-RSRP of the PSSCH scheduled by the PSCCH (i.e., the SL-RSRP of the PSSCH sent in the same time slot as the PSCCH) is measured.

[0060] If the measured SL-RSRP is greater than the SL-RSRP threshold, and the first sidelink control information received by the terminal device contains the "Resource reservation period" field, the terminal device will m The terminal device determines the corresponding Q time slots based on the resource reservation period carried in the first sideline control information it has intercepted. The terminal device assumes that it has also received the same first sideline control information in the Q time slots. The terminal device will determine the time slot t m Whether the resources indicated by the "Time resource assignment" and "Frequency resource assignment" fields of the received first sideline control information and the Q assumed received first sideline control information overlap with the resource R(x,y) or a series of periodic resources corresponding to the resource R(x,y). If they overlap, the corresponding resource R(x,y) is excluded from the set A. (Represents rounding up). Tscal is equal to the value of T2 converted to milliseconds. Prx is the resource reservation period carried in the first side control information detected. Optionally, a series of periodic resources corresponding to the resource R(x,y) is R(x,y+j*Ptxlg), j=0,1,2,…,Cresel-1. Cresel is related to the random count value generated by the terminal device, and Ptxlg is the number after Ptx is converted into logical time slots. Ptx is the resource reservation period of the terminal device. For example, in sub-figure (b) of Figure 4, Cresel is 3, which indicates 3 periodic resources corresponding to the resource R(x,y) (including R(x,y)).

[0061] For example, in sub-figure (b) of FIG4, when the first sideline control information received by the terminal device contains the "Resource reservation period" field, if the terminal device is in time slot t m The first side control information in the PSCCH is detected on the resource E(v,m). The resource reservation period in the first side control information is Prx. Assuming that the Q value is calculated to be 1, the terminal device will assume that in time slot t m+Prxlg The terminal device will determine whether the first side control information of the same content is received in time slot tm The first sideline control information received and the assumption that the m+Prxlg Whether the resources 1, 2, 3, 4, 5, 6 indicated by the "Time resource assignment" and "Frequency resource assignment" fields of the received first side control information overlap with the resource R(x, y) or a series of periodic resources corresponding to the resource R(x, y); if they overlap and the RSRP condition is met, the resource R(x, y) is excluded from the resource set A.

[0062] If the SL-RSRP measured by the terminal device is greater than the SL-RSRP threshold, and the first sidelink control information received by the terminal device does not contain the "Resource reservation period" field, the terminal device only determines the time slot t m Whether the resources indicated by the "Time resource assignment" and "Frequency resource assignment" fields of the received first side control information overlap with the resource R(x,y) or a series of resources corresponding to the resource R(x,y); if so, exclude the resource R(x,y) from the resource set A.

[0063] For example, in sub-figure (b) of FIG4, when the first sideline control information received by the terminal device does not contain the "Resource reservation period" field, if the terminal device is in time slot t m If the first sidelink control information in the PSCCH is detected on the resource E(v,m), the terminal device determines whether the resources 1, 2, and 3 indicated by the "Time resource assignment" and "Frequency resource assignment" fields in the first sidelink control information overlap with the resource R(x,y) or a series of periodic resources corresponding to the resource R(x,y). If they overlap and the RSRP condition is met, the resource R(x,y) is excluded from the resource set A.

[0064] If the remaining resources in resource set A are less than M after the above resources are excluded total *X, the SL-RSRP threshold is raised by 3dB, and Step 1 is repeated. The physical layer reports the excluded resource set A as a candidate resource set to the upper layer.

[0065] Step 2: The upper layer randomly selects a resource from the reported candidate resource set to send data. That is, the terminal device randomly selects a resource from the candidate resource set to send data.

[0066] It should be noted that:

[0067] (1) The RSRP thresholds are determined by the priority level P1 carried in the PSCCH detected by the terminal device and the priority level P2 of the data to be transmitted by the terminal device. The configuration of the resource pool used by the terminal device includes a SL-RSRP threshold table that contains the SL-RSRP thresholds corresponding to all priority combinations. The resource pool configuration can be network-configured or pre-configured.

[0068] For example, as shown in Table 1, assuming that the priority levels of P1 and P2 are both 0-7, the SL-RSRP thresholds corresponding to different priority combinations are expressed as γ ij Indicates that, where γ ij Here, i is the value of the priority level P1, and j is the value of the priority level P2.

[0069] Table 1: SL-RSRP threshold table

[0070] When a terminal device monitors a PSCCH sent by another terminal device, it obtains the priority P1 and the priority P2 of the data to be sent carried in the first sidelink control information transmitted in the PSCCH, and determines the SL-RSRP threshold by looking up Table 1.

[0071] (2) Whether the terminal device uses the measured PSCCH-RSRP or the PSSCH-RSRP scheduled by the PSCCH to compare with the SL-RSRP threshold depends on the resource pool configuration of the resource pool used by the terminal device. The resource pool configuration can be network-configured or pre-configured.

[0072] (3) The possible values ​​of X and X are {20%, 35%, 50%}. The configuration of the resource pool used by the terminal device includes a correspondence between priorities and the possible values. The terminal device determines the value of X based on the priority of the data to be sent and the correspondence. The resource pool configuration can be configured by the network or pre-configured.

[0073] (4) Convert the resource reservation period into a logical time slot:

[0074] As mentioned above, the terminal device sends a first side control information to indicate the time-frequency resources and reserves the resources to be used next. When listening, the terminal device that performs resource selection will decode the first side control information sent by other terminal devices, learn the resources reserved by other terminal devices, and exclude the corresponding resources during resource selection, thereby avoiding resource collisions. When performing resource exclusion, the terminal device that performs resource selection will convert the physical time (for example, 100 milliseconds) indicated by the "resource reservation period" field in the decoded first side control information into the corresponding number of logical time slots, and then use the number of logical time slots to exclude resources:

[0075] In the above formula, Prsvp is the resource reservation period, such as the resource reservation period indicated by the "resource reservation period" in the first sidelink control information intercepted by the terminal device, the resource reservation period allowed in the resource pool, or the resource reservation period of the terminal device. P'rsvp is the calculated number of corresponding logical time slots. T'max is the number of time slots in the resource pool or the transmitting resource pool belonging to the terminal device within one SFN (System Frame Number) period or 10240 milliseconds.

[0076] The above description describes a single-side link (SL) communication method within NR-V2X. This involves a terminal device autonomously selecting transmission resources through resource sensing and independently transmitting data on the sidelink. This SL communication method can also be applied to various SL communications, such as direct communication between handheld devices and between pedestrians and vehicles.

[0077] 5. Multi-beam system

[0078] NR / 5G system design goals include wide-bandwidth communications in high-frequency bands (e.g., bands above 6 GHz). As the operating frequency increases, path loss increases during transmission, impacting the coverage capabilities of high-frequency systems. To effectively ensure high-band NR system coverage, an effective technical solution is to use massive antenna arrays (Massive MIMO) to form shaped beams with greater gain, overcome propagation loss, and ensure system coverage.

[0079] Millimeter-wave antenna arrays, due to their shorter wavelengths, smaller antenna array spacing, and smaller apertures, allow more physical antenna arrays to be integrated into a two-dimensional antenna array of limited size. At the same time, due to the limited size of millimeter-wave antenna arrays, digital beamforming cannot be used due to factors such as hardware complexity, cost, and power consumption. Instead, analog beamforming is typically used, which enhances network coverage while reducing device implementation complexity.

[0080] In typical existing 2G / 3G / 4G systems, a cell (sector) uses a wide beam to cover the entire cell. Therefore, at every moment, UEs within the cell's coverage area have the opportunity to obtain transmission resources allocated by the system.

[0081] The NR / 5G Multi-beam system uses different beams to cover the entire cell. That is, each beam covers a smaller area, and the effect of multiple beams covering the entire cell is achieved through time sweeping.

[0082] Figure 5 shows schematic diagrams of systems without and with beamforming. The left sub-figure (a) shows the traditional LTE and NR systems without beamforming, and the right sub-figure (b) shows the NR system with beamforming.

[0083] In the left sub-figure (a), the LTE / NR network side uses a wide beam to cover the entire cell, and terminal devices 1-5 can receive network signals at any time.

[0084] In contrast, in the right sub-figure (b), the network side uses narrower beams (such as beams 1-4 in the figure), and uses different beams at different times to cover different areas in the cell. For example, at time 1, the NR network side uses beam 1 to cover the area where terminal device 1 is located; at time 2, the NR network side uses beam 2 to cover the area where terminal device 2 is located; at time 3, the NR network side uses beam 3 to cover the area where terminal devices 3 and 4 are located; and at time 4, the NR network side uses beam 4 to cover the area where terminal device 5 is located.

[0085] In the right sub-figure (b), because the network uses narrower beams, the transmission energy can be more concentrated, thus covering a longer distance. At the same time, because the beams are narrow, each beam can only cover a part of the cell, so analog beamforming is "trading time for space."

[0086] Analog beamforming can be used not only in network equipment but also in terminal devices. Furthermore, analog beamforming can be used not only for signal transmission (called transmit beamforming) but also for signal reception (called receive beamforming).

[0087] Currently, issues related to SL systems operating at high frequencies are being discussed. When SL systems operate at high frequencies, beamforming is inevitably introduced, such as using a transmit beam for transmission or a receive beam for reception.

[0088] In the resource selection mechanism of the SL system provided by related technologies, terminal devices exclude resources within the listening window based on the listening results within the window. With the introduction of beamforming, terminal devices perform omnidirectional reception in some time slots within the listening window, while using beamforming for directional reception in other time slots. When using beamforming for reception, terminal devices can only detect sidelink control information in a specific direction, resulting in incomplete detection results. Therefore, how to process sidelink control information detected using beamforming to exclude resources requires further research.

[0089] In this application, the term "beam" is also referred to as a "spatial domain transmission filter," and the two have the same meaning. Accordingly, a "receive beam" is also referred to as a "spatial domain receive filter," a "receiver spatial domain filter," a "spatial domain transmission filter for reception," or other names, and a "transmit beam" is also referred to as a "spatial domain transmit filter," a "transmitter spatial domain filter," a "spatial domain transmission filter for transmission," or other names, and this application does not limit these terms.

[0090] In addition, in this application, a "time unit" can be a time slot, a subframe, or other time units, and this application does not limit this. For the "time unit" mentioned elsewhere in this article, please refer to this explanation and will not be repeated.

[0091] In addition, in this application, "signal quality" can be RSRP, or other parameters used to characterize signal quality, such as RSRQ (Reference Signal Receiving Quality), SINR (Signal to Interference plus Noise Ratio), RSSI (Received Signal Strength Indicator), etc., and this application does not limit this. For example, "signal quality" is RSRP, and "signal quality threshold" is "RSRP threshold". For the "signal quality" mentioned elsewhere in this article, please refer to this explanation and will not be repeated.

[0092] The technical solution of this application will be introduced and explained through several embodiments below.

[0093] Please refer to Figure 6, which shows a flow chart of a resource exclusion method provided by an embodiment of the present application. The method can be applied to the network architecture shown in Figure 1, for example, the method can be executed by a terminal device. The method may include at least one of the following steps 610 to 620:

[0094] Step 610: Receive sideline control information within a first time unit.

[0095] In some embodiments, the terminal device receives the sideline control information in a first manner within a first time unit.

[0096] In some embodiments, the first mode is a mode of receiving using a spatial transmission filter. The terminal device receives the sideline control information using the spatial transmission filter within the first time unit. In other words, the terminal device receives the sideline control information using a beamform within the first time unit.

[0097] Step 620: exclude resources according to the side control information.

[0098] The terminal device excludes resources based on the received side control information.

[0099] In some embodiments, the terminal device performs resource exclusion based on sidelink control information received in a first manner within a first time unit.

[0100] In some embodiments, the terminal device performs resource exclusion based on sidelink control information received using a spatial transmission filter within a first time unit.

[0101] In some embodiments, the terminal device determines a resource selection window and a resource listening window. Exemplarily, the resource selection window is n+T1 to n+T2, where T1 and T2 refer to the above description. Exemplarily, the resource listening window is n-T0 to nT proc,0 (excluding nT proc,0 ), T0 and T proc,0 Refer to the above description. Wherein, n is the time unit for triggering resource selection, or triggering resource reselection, or triggering the physical layer to report the candidate resource set by the higher layer. The terminal device initializes the candidate resource set, and the candidate resource set includes the candidate resources within the resource selection window. Denote any candidate resource as R(x,y), where x is used to indicate the frequency domain position of the candidate resource, such as the frequency domain starting subchannel, and y is used to indicate the time domain position of the candidate resource, such as the time unit where the candidate resource is located. Denote the number of candidate resources in the initialized candidate resource set as M total The terminal device uses a spatial transmission filter for reception within a first time unit and excludes resources from the candidate resource set based on the sidelink control information received within the first time unit. The first time unit is within the resource listening window. The sidelink control information is the first sidelink control information introduced above, i.e., the sidelink control information carried by the PSCCH.

[0102] Several embodiments of resource exclusion based on side control information provided by this application will be introduced below.

[0103] In some embodiments, the terminal device determines a target signal quality threshold based on a first spatial reception filter, where the first spatial reception filter is a spatial transmission filter corresponding to the side control information; and performs resource exclusion based on the target signal quality threshold and the signal quality corresponding to the received side control information.

[0104] In some embodiments, the first spatial domain reception filter is a spatial domain transmission filter for receiving sideline control information, or in other words, the first spatial domain reception filter is a spatial domain transmission filter used for reception within the first time unit.

[0105] In some embodiments, the terminal device determines the target signal quality threshold in the signal quality threshold table corresponding to the first spatial domain reception filter based on the priority indicated by the side control information and the priority of the terminal device data transmission. Optionally, one spatial domain reception filter corresponds to one signal quality threshold table; or, multiple spatial domain reception filters correspond to one signal quality threshold table. The signal quality threshold table includes signal quality thresholds corresponding to all priority combinations. The priority combination refers to the combination of the priority indicated by the side control information and the priority of the terminal device data transmission. Taking RSRP as an example, the signal quality may optionally correspond to one RSRP threshold table. Optionally, multiple spatial domain reception filters may correspond to one RSRP threshold table. Exemplarily, all spatial domain reception filters of the terminal device correspond to the same RSRP threshold table. The RSRP threshold table includes RSRP thresholds corresponding to all priority combinations, and the details may refer to the above description.

[0106] In some embodiments, for any candidate resource in the candidate resource set, if the signal quality corresponding to the sidelink control information is greater than a target signal quality threshold, and the resource determined based on the sidelink control information overlaps with the resource corresponding to the candidate resource, the terminal device excludes the candidate resource from the candidate resource set. In some embodiments, the signal quality corresponding to the sidelink control information refers to the signal quality of the PSCCH carrying the sidelink control information, or the signal quality of the PSSCH scheduled by the PSCCH.

[0107] Exemplarily, the terminal device receives sidelink control information using a first spatial domain reception filter within a first time unit, measures the RSRP of the PSCCH carrying the sidelink control information or the RSRP of the PSSCH scheduled by the PSCCH, determines a corresponding RSRP threshold table based on the first spatial domain reception filter, and determines the RSRP threshold in the RSRP threshold table corresponding to the above-mentioned first spatial domain reception filter based on the priority indicated by the sidelink control information and the priority of the terminal device data transmission. If the RSRP obtained by the measurement is greater than the determined RSRP threshold, and the resources determined by the terminal device based on the sidelink control information overlap with the resources corresponding to R(x,y), R(x,y) is excluded from the candidate resource set, where x is used to indicate the frequency domain position of the candidate resource and y is used to indicate the time domain position of the candidate resource.

[0108] In some embodiments, the resources determined based on the sidelink control information include resources indicated by the sidelink control information. Exemplarily, they are resources indicated by the sidelink control information for the same TB transmission. Exemplarily, they are resources indicated by the "Time resource assignment" and "Frequency resource assignment" fields in the sidelink control information.

[0109] In some embodiments, the terminal device determines the corresponding Q time units based on the time unit in which the side control information is received and the resource reservation period indicated by the side control information. The terminal device assumes that the side control information with the same content will be received within the Q time units, where Q is a positive integer. Specifically, taking the time unit in which the side control information is received as the starting point, a first interval is determined based on the resource reservation period indicated by the side control information, and the corresponding Q time units are determined by calculating from the starting point using the first interval. The resources determined based on the side control information include: the resources indicated by the side control information received by the terminal device and the resources indicated by the side control information assumed to be received. Exemplarily, the resources determined based on the side control information include: the resources indicated by each of the received side control information and the side control information assumed to be received for the same TB transmission. Exemplarily, the resources determined based on the side control information include: the resources indicated by the "Time resource assignment" and "Frequency resource assignment" fields of each of the received side control information and the side control information assumed to be received.

[0110] In some embodiments, the resource corresponding to the candidate resource includes the candidate resource. For example, if the candidate resource is R(x, y), the resource corresponding to the candidate resource is R(x, y).

[0111] In some embodiments, the resources corresponding to the candidate resource include: the candidate resource and J-1 resources that have the same frequency domain position as the candidate resource and are separated by a second interval in the time domain. J is determined based on a random count value generated by the terminal device, the second interval is determined based on the resource reservation period of the terminal device, and J is a positive integer. For example, if the candidate resource is R(x,y), the resources corresponding to the candidate resource include: R(x,y) and J-1 resources that have the same frequency domain position as R(x,y) and are separated by a second interval in the time domain.

[0112] For example, as shown in FIG7 , the terminal device determines the resource selection window 10 from n+T1 to n+T2 and the resource selection window 11 from n-T0 to nT1. proc,0 The resource listening window is 20, n is the time slot when the higher layer triggers the physical layer to report the candidate resource set. The terminal device initializes the candidate resource set, which includes the candidate resources within the resource selection window 10. Any candidate resource is denoted as R(x,y). Assume that the terminal device uses receiving beams 1 to 4 for reception. The receiving beams 1 to 4 correspond to RSRP threshold tables 1 to 4 respectively. In time slot t m On resource 1, the terminal device uses receiving beam 2 to detect the sidelink control information, and the terminal device determines the RSRP threshold in RSRP threshold table 2 corresponding to receiving beam 2 according to the priority indicated by the sidelink control information and the priority of the terminal device data transmission. If the RSRP of the PSCCH carrying the sidelink control information or the PSSCH scheduled by the PSCCH (that is, the PSCCH on resource 1 or the PSSCH scheduled by the PSCCH) is greater than the determined RSRP threshold, and the resources determined according to the sidelink control information overlap with the resources corresponding to R(x,y), then R(x,y) is excluded from the candidate resource set.

[0113] Optionally, the resources corresponding to R(x, y) are the three resources including R(x, y) in FIG7 , and the interval between them is determined according to the resource reservation period of the terminal device.

[0114] Optionally, the resource determined according to the sideline control information is time slot t m Resources 1, 2 and 3 indicated by the sidelink control information received on resource 1.

[0115] Optionally, the terminal device utilizes the time slot t m The resource reservation period Prx indicated by the side control information received on resource 1 determines Prxlg, that is, the resource reservation period Prx is converted into the number of logical time slots, for example, according to the number of time slots in the resource pool. The terminal device receives the time slot t of the side control information. m As the starting point, with Prxlg as the interval, determine the corresponding Q time slots. Assuming Q is equal to 1, the time slot t where resource 4 is located is determined. m+PrxlgThe terminal is assumed to be at t m+Prxlg The same side control information will be received on the same side control information, and the resources determined according to the side control information include time slot t m The resources 1-3 and time slot t indicated by the side control information received m+Prxlg It is assumed above that resources 4-6 indicated by the received sidelink control information (t1, t2, t3, t4, ...) represent a set of time slots belonging to the resource pool.

[0116] In the above embodiment, the spatial transmission filter is associated with the signal quality threshold. The terminal device determines the signal quality threshold for resource exclusion using the received sideline control information based on the spatial transmission filter used to receive the sideline control information, thereby realizing the combination of the spatial transmission filter used to receive the sideline control information and the resource selection mechanism.

[0117] In some embodiments, when the first spatial domain reception filter and the first spatial domain transmission filter meet the first condition, the terminal device uses the received side control information to exclude resources; or, when the first spatial domain reception filter and the first spatial domain transmission filter do not meet the first condition, the terminal device does not use the received side control information to exclude resources; wherein the first spatial domain reception filter is the spatial domain transmission filter corresponding to the side control information.

[0118] In some embodiments, the first spatial domain reception filter is a spatial domain transmission filter for receiving sideline control information, or in other words, the first spatial domain reception filter is a spatial domain transmission filter used for reception within the first time unit.

[0119] In some embodiments, the first condition includes: the first spatial domain receive filter covers the first spatial domain transmit filter. That is, when the first spatial domain receive filter covers the first spatial domain transmit filter, the terminal device uses the received side control information to exclude resources; or, when the first spatial domain receive filter does not cover the first spatial domain transmit filter, the terminal device does not use the received side control information to exclude resources. Optionally, the first spatial domain receive filter covers the first spatial domain transmit filter, which may also mean that the beamwidth corresponding to the first spatial domain receive filter is greater than or equal to the beamwidth corresponding to the first spatial domain transmit filter.

[0120] In some embodiments, the first condition includes: there is a correspondence between the first spatial domain receiving filter and the first spatial domain transmitting filter. That is, when there is a correspondence between the first spatial domain receiving filter and the first spatial domain transmitting filter, the terminal device uses the received side control information to exclude resources; or, when there is no correspondence between the first spatial domain receiving filter and the first spatial domain transmitting filter, the terminal device does not use the received side control information to exclude resources. Exemplarily, there is a correspondence between the spatial domain transmitting filter (or transmitting beam) of the terminal device and the spatial domain receiving filter (or receiving beam). The correspondence can be one-to-one, or many-to-one, or one-to-many, or many-to-many, and this application does not limit this. The terminal device can determine the corresponding spatial domain receiving filter through the spatial domain transmitting filter, or determine the corresponding spatial domain transmitting filter through the spatial domain receiving filter.

[0121] In some embodiments, the first spatial domain transmit filter is a spatial domain transmit filter determined by the terminal device for data transmission.

[0122] In some embodiments, the first spatial transmission filter is a candidate resource set for resource exclusion or a spatial transmission filter corresponding to a candidate resource. A corresponding relationship exists between the candidate resource set or candidate resource and the spatial transmission filter. The corresponding spatial transmission filter can be determined based on the candidate resource set or candidate resource, or the corresponding candidate resource set or candidate resource can be determined based on the spatial transmission filter.

[0123] In some embodiments, side control information is not used for resource exclusion, including: not excluding resources from the candidate resource set; or, not excluding resources from the candidate resource set corresponding to the first spatial domain transmit filter; or, not excluding resources from the candidate resources corresponding to the first spatial domain transmit filter.

[0124] In some embodiments, a terminal device receives sidelink control information using a first spatial domain reception filter within a first time unit. If the first spatial domain reception filter can cover the first spatial domain transmission filter determined by the terminal device for data transmission, or can cover the first spatial domain transmission filter corresponding to the candidate resource set or the first spatial domain transmission filter corresponding to the candidate resource R(x,y), the signal quality of the PSCCH carrying the sidelink control information or the signal quality of the PSSCH scheduled by the PSCCH is measured. If the measured signal quality is greater than a signal quality threshold, and the resource determined by the terminal device based on the sidelink control information overlaps with the resource corresponding to R(x,y), R(x,y) is excluded from the candidate resource set. The above-mentioned signal quality threshold is determined based on the priority indicated by the sidelink control information and the priority of the terminal device's data transmission.

[0125] The resources determined according to the side control information and the resources corresponding to R(x, y) are consistent with those in the above embodiment and will not be described in detail here.

[0126] In some embodiments, the terminal device receives side control information using a first spatial domain reception filter within a first time unit. If the first spatial domain reception filter does not cover the first spatial domain transmission filter determined by the terminal device for data transmission, the terminal device does not exclude resources from the candidate resource set.

[0127] In some embodiments, the terminal device receives side control information using the first spatial domain reception filter within the first time unit. If the first spatial domain reception filter does not cover the first spatial domain transmission filter corresponding to the candidate resource set, the terminal device does not exclude resources for the candidate resource set. However, if there are other candidate resource sets and the first spatial domain reception filter can cover the spatial domain transmission filters corresponding to other candidate resource sets, the other candidate resource sets can be excluded.

[0128] In some embodiments, the terminal device receives side control information using a first spatial domain receiving filter within a first time unit. If the first spatial domain receiving filter does not cover the first spatial domain transmitting filter corresponding to the candidate resource R(x,y), the terminal device does not exclude resources for the R(x,y). However, if it can cover the spatial domain transmitting filters corresponding to other R(x,y), the terminal device can exclude resources for other R(x,y).

[0129] For example, as shown in FIG7 , the terminal device determines the resource selection window 10 from n+T1 to n+T2 and the resource selection window 11 from n-T0 to nT1. proc,0 The resource listening window is 20, n is the time slot when the high layer triggers the physical layer to report the candidate resource set, the terminal device initializes the candidate resource set, and the candidate resource set includes the candidate resources in the resource selection window 10. Any candidate resource is denoted as R(x,y).

[0130] Optionally, the terminal device determines a transmission beam for data transmission. Optionally, the terminal device determines a corresponding transmission beam based on a set of candidate resources. Optionally, the terminal device determines a transmission beam corresponding to a candidate resource R(x,y). In time slot t mOn resource 1, the terminal device uses a receiving beam to detect the side control information. If the receiving beam covers the transmitting beam determined above, the terminal device measures the RSRP of the PSCCH carrying the side control information or the PSSCH scheduled by the PSCCH (i.e., the PSCCH on resource 1 or the PSSCH scheduled by the PSCCH). If the measured RSRP is greater than the RSRP threshold, and the resources determined according to the side control information overlap with the resources corresponding to R(x,y), R(x,y) is excluded from the candidate resource set. The above RSRP threshold is determined according to the priority indicated by the side control information and the priority of the terminal device data transmission. Among them, the resources determined according to the side control information and the resources corresponding to R(x,y) can be found in the above introduction and will not be repeated here.

[0131] Optionally, the terminal device determines a transmit beam for data transmission, and in time slot t m On resource 1, the terminal device uses a receive beam to detect side control information. If the receive beam does not cover the determined transmit beam, the terminal device does not exclude resources based on the detected side control information. For example, resource exclusion is not performed on the candidate resource set based on the detected side control information.

[0132] Optionally, the terminal device determines its corresponding transmit beam according to the candidate resource set, and in time slot t m On resource 1 of the received signal, the terminal device uses the receiving beam to detect the side control information. If the receiving beam does not cover the above-determined transmitting beam, the terminal device does not exclude resources based on the detected side control information. For example, the candidate resource set is not excluded based on the detected side control information. For example, the candidate resource set is not excluded based on the detected side control information, but if there are other candidate resource sets and in time slot t m If the receiving beam used in can cover the transmitting beams corresponding to other candidate resource sets, the other candidate resource sets can be excluded.

[0133] Optionally, the terminal device determines the transmit beam corresponding to the candidate resource R(x,y) and sends the signal to the user at time slot t m On resource 1, the terminal device uses a receive beam to detect side control information. If the receive beam does not cover the determined transmit beam, the terminal device does not exclude resources based on the detected side control information. For example, resource exclusion for R(x,y) in the candidate resource set is not performed based on the detected side control information. However, if the receive beam covers the transmit beam corresponding to other candidate resources, resource exclusion for other candidate resources may be performed.

[0134] In the above embodiment, the terminal device determines whether to use the received side control information for resource exclusion based on the coverage or correspondence between the spatial transmission filter used for receiving the side control information and the spatial transmission filter used for sending. In the case of coverage or correspondence, the side control information received by using the above spatial transmission filter is used for resource exclusion. In the case of no coverage or no correspondence, the side control information received by using the above spatial transmission filter may not be used for resource exclusion, thereby fully considering the reference value of the side control information received by using the spatial transmission filter to the resource exclusion process and improving the accuracy of resource exclusion.

[0135] In some embodiments, when the first spatial domain reception filter and the first spatial domain transmission filter meet the first condition, resources are excluded based on the first signal quality threshold and the received side control information; or, when the first spatial domain reception filter and the first spatial domain transmission filter do not meet the first condition, resources are excluded based on the second signal quality threshold and the received side control information; wherein the first spatial domain reception filter is the spatial domain transmission filter corresponding to the side control information.

[0136] For the introduction and description of the first condition and the first spatial domain transmit filter, please refer to the above and will not be repeated here.

[0137] In some embodiments, the first signal quality threshold and the second signal quality threshold are determined from two different signal quality threshold tables. Exemplarily, the first signal quality threshold is determined from a first signal quality threshold table, and the second signal quality threshold is determined from a second signal quality threshold table, and the first signal quality threshold table and the second signal quality threshold table are different.

[0138] Exemplarily, the terminal device receives side control information using a first spatial domain reception filter within a first time unit. If the first spatial domain reception filter can cover the first spatial domain transmission filter determined by the terminal device for data transmission, or can cover the first spatial domain transmission filter corresponding to the candidate resource set, or can cover the first spatial domain transmission filter corresponding to the candidate resource R(x,y), then the terminal device determines a first signal quality threshold in the first signal quality threshold table based on the priority indicated by the side control information and the priority of the terminal device's data transmission. The terminal device measures the signal quality of the PSCCH carrying the side control information or the signal quality of the PSSCH scheduled by the PSCCH. If the measured signal quality is greater than the first signal quality threshold, and the resource determined by the terminal device based on the side control information overlaps with the resource corresponding to R(x,y), then R(x,y) is excluded from the candidate resource set.

[0139] Exemplarily, the terminal device receives side control information using a first spatial domain reception filter within a first time unit. If the first spatial domain reception filter does not cover the first spatial domain transmission filter determined by the terminal device for data transmission, or does not cover the first spatial domain transmission filter corresponding to the candidate resource set, or does not cover the first spatial domain transmission filter corresponding to the candidate resource R(x,y), the terminal device determines a second signal quality threshold in a second signal quality threshold table based on the priority indicated by the side control information and the priority of the terminal device's data transmission. The terminal device measures the signal quality of the PSCCH carrying the side control information or the signal quality of the PSSCH scheduled by the PSCCH. If the measured signal quality is greater than the second signal quality threshold, and the resource determined by the terminal device based on the side control information overlaps with the resource corresponding to R(x,y), R(x,y) is excluded from the candidate resource set.

[0140] The resources determined according to the side control information and the resources corresponding to R(x, y) are consistent with those in the above embodiment and will not be described in detail here.

[0141] Exemplarily, the first signal quality threshold table is configured by the network, or pre-configured, or depends on the implementation of the terminal device, or is a preset value specified by the standard.

[0142] Exemplarily, the second signal quality threshold table is configured by the network, or pre-configured, or depends on the implementation of the terminal device, or is a preset value specified by the standard.

[0143] Exemplarily, the first signal quality threshold table is calculated based on the second signal quality threshold table. Exemplarily, the first signal quality threshold table is obtained by subtracting a first value from each signal quality threshold in the second signal quality threshold table. The first value is configured by the network, or preconfigured, or depends on terminal device implementation, or is a preset value specified in a standard. The second signal quality threshold table is configured by the network, or preconfigured, or depends on terminal device implementation, or is a preset value specified in a standard.

[0144] Exemplarily, the second signal quality threshold table is calculated based on the first signal quality threshold table. Exemplarily, the second signal quality threshold table is obtained by adding a second value to each signal quality threshold in the first signal quality threshold table. The second value is configured by the network, or pre-configured, or depends on terminal device implementation, or is a preset value specified in a standard. The first signal quality threshold table is configured by the network, or pre-configured, or depends on terminal device implementation, or is a preset value specified in a standard.

[0145] Exemplarily, the first signal quality threshold table and the second signal quality threshold table are calculated based on the third signal quality threshold table. Exemplarily, the first signal quality threshold table is obtained by subtracting a third value from each signal quality threshold in the third signal quality threshold table, and the second signal quality threshold table is obtained by adding a fourth value to each signal quality threshold in the third signal quality threshold table. The third value and / or the fourth value are configured by the network, or pre-configured, or depend on the implementation of the terminal device, or are preset values ​​specified by the standard. The third signal quality threshold table is configured by the network, or pre-configured, or depends on the implementation of the terminal device, or are preset values ​​specified by the standard.

[0146] For example, as shown in FIG7 , the terminal device determines the resource selection window 10 from n+T1 to n+T2 and the resource selection window 11 from n-T0 to nT1. proc,0 The resource listening window is 20, n is the time slot when the high layer triggers the physical layer to report the candidate resource set, the terminal device initializes the candidate resource set, and the candidate resource set includes the candidate resources in the resource selection window 10. Any candidate resource is denoted as R(x,y).

[0147] Optionally, the terminal device determines a transmission beam for data transmission. Optionally, the terminal device determines a corresponding transmission beam based on a set of candidate resources. Optionally, the terminal device determines a transmission beam corresponding to a candidate resource R(x,y). In time slot t m On resource 1, the terminal device uses a receive beam to detect sidelink control information. If the receive beam covers the transmit beam determined above, the terminal device determines a first RSRP threshold in the first RSRP threshold table based on the priority indicated by the sidelink control information and the priority of the terminal device's data transmission. The terminal device measures the RSRP of the PSCCH carrying the sidelink control information or the PSSCH scheduled by the PSCCH (i.e., the PSCCH on resource 1 or the PSSCH scheduled by the PSCCH). If the measured RSRP is greater than the first RSRP threshold and the resource determined based on the sidelink control information overlaps with the resource corresponding to R(x,y), R(x,y) is excluded from the candidate resource set.

[0148] Optionally, the terminal device determines a transmission beam for data transmission. Optionally, the terminal device determines a corresponding transmission beam based on a set of candidate resources. Optionally, the terminal device determines a transmission beam corresponding to a candidate resource R(x,y). In time slot t mOn resource 1, the terminal device uses a receive beam to detect the sidelink control information. If the receive beam does not cover the transmit beam determined above, the terminal device determines a second RSRP threshold in the second RSRP threshold table based on the priority indicated by the sidelink control information and the priority of the terminal device's data transmission. The terminal device measures the RSRP of the PSCCH carrying the sidelink control information or the PSSCH scheduled by the PSCCH (i.e., the PSCCH on resource 1 or the PSSCH scheduled by the PSCCH). If the measured RSRP is greater than the second RSRP threshold and the resource determined based on the sidelink control information overlaps with the resource corresponding to R(x,y), R(x,y) is excluded from the candidate resource set.

[0149] In the above embodiment, the terminal device determines the signal quality threshold used for resource exclusion based on the coverage or correspondence between the spatial transmission filter used for receiving the side control information and the spatial transmission filter used for sending; for example, in the case of coverage or correspondence, the above signal quality threshold can be lower, so that candidate resources are easier to be excluded; in the case of no coverage or no correspondence, the above signal quality threshold can be higher, so that candidate resources are less likely to be excluded, thereby fully considering the reference value of the side control information received using the spatial transmission filter for the resource exclusion process, and improving the accuracy of resource exclusion.

[0150] In some embodiments, when the first spatial domain reception filter and the first spatial domain transmission filter meet the first condition, resources are excluded based on the first priority and the received side control information; or, when the first spatial domain reception filter and the first spatial domain transmission filter do not meet the first condition, resources are excluded based on the second priority and the received side control information; wherein the first spatial domain reception filter is the spatial domain transmission filter corresponding to the above-mentioned side control information.

[0151] For the introduction and description of the first condition and the first spatial domain transmit filter, please refer to the above and will not be repeated here.

[0152] In some embodiments, resource exclusion is performed based on the first priority and the side control information, including: determining a third signal quality threshold in a signal quality threshold table based on the first priority and the priority of terminal device data transmission, and excluding resources based on the third signal quality threshold and the signal quality corresponding to the side control information.

[0153] In some embodiments, resource exclusion is performed based on the second priority and the side control information, including: determining a fourth signal quality threshold in a signal quality threshold table based on the second priority and the priority of terminal device data transmission, and excluding resources based on the fourth signal quality threshold and the signal quality corresponding to the side control information.

[0154] Exemplarily, the terminal device receives the side control information using the first spatial domain reception filter within the first time unit. If the first spatial domain reception filter can cover the first spatial domain transmission filter determined by the terminal device for data transmission, or can cover the first spatial domain transmission filter corresponding to the candidate resource set, or can cover the first spatial domain transmission filter corresponding to the candidate resource R(x,y), then the terminal device determines the signal quality threshold in the signal quality threshold table according to the first priority and the priority of the terminal device data transmission. The terminal device measures the signal quality of the PSCCH carrying the side control information or the signal quality of the PSSCH scheduled by the PSCCH. If the measured signal quality is greater than the above-determined signal quality threshold, and the resource determined by the terminal device according to the side control information overlaps with the resource corresponding to R(x,y), then R(x,y) is excluded from the candidate resource set.

[0155] Exemplarily, the terminal device receives the side control information using the first spatial domain reception filter within the first time unit. If the first spatial domain reception filter does not cover the first spatial domain transmission filter determined by the terminal device for data transmission, or does not cover the first spatial domain transmission filter corresponding to the candidate resource set, or does not cover the first spatial domain transmission filter corresponding to the candidate resource R(x,y), the terminal device determines the signal quality threshold in the signal quality threshold table according to the second priority and the priority of the terminal device data transmission. The terminal device measures the signal quality of the PSCCH carrying the side control information or the signal quality of the PSSCH scheduled by the PSCCH. If the measured signal quality is greater than the above-determined signal quality threshold, and the resource determined by the terminal device according to the side control information overlaps with the resource corresponding to R(x,y), R(x,y) is excluded from the candidate resource set.

[0156] The resources determined according to the side control information and the resources corresponding to R(x, y) are consistent with those in the above embodiment and will not be described in detail here.

[0157] In some embodiments, the first priority and / or the second priority is determined according to the priority indicated by the sideline control information.

[0158] Exemplarily, the priority value of the first priority is recorded as the first priority value, and the priority value of the priority indicated by the side control information is recorded as the third priority value, and the first priority value is the third priority value minus the fifth value. If the result of subtracting the fifth value from the third priority value is less than the minimum value of the priority value, then the first priority value is the minimum value of the priority value, that is, the highest priority. Among them, the fifth value is configured by the network, or pre-configured, or depends on the implementation of the terminal device, or is a preset value specified by the standard. Exemplarily, the first priority is the priority indicated by the side control information, that is, the first priority value is equal to the third priority value.

[0159] Exemplarily, the priority value of the second priority is recorded as the second priority value, and the priority value of the priority indicated by the side control information is recorded as the third priority value. The second priority value is the third priority value plus the sixth value. If the result of adding the third priority value and the sixth value is greater than the maximum priority value, then the second priority value is the maximum priority value, that is, the lowest priority. The sixth value is configured by the network, or pre-configured, or depends on the implementation of the terminal device, or is a preset value specified by the standard. Exemplarily, the second priority is the priority indicated by the side control information, that is, the second priority value is equal to the third priority value.

[0160] Exemplarily, the first priority value is the minimum value of the priority values, that is, the first priority is the highest priority.

[0161] Exemplarily, the first priority value is less than or equal to a priority value threshold, i.e., the first priority is higher than or equal to a priority threshold. The above-mentioned priority value threshold and / or priority threshold are configured by the network, or pre-configured, or depend on the implementation of the terminal device, or are preset values ​​specified by the standard.

[0162] In the above examples, it is only taken that the smaller the priority value, the higher the priority. In some other examples, the larger the priority value, the higher the priority, which is not limited in this application.

[0163] For example, as shown in FIG7 , the terminal device determines the resource selection window 10 from n+T1 to n+T2 and the resource selection window 11 from n-T0 to nT1. proc,0 The resource listening window is 20, n is the time slot when the high layer triggers the physical layer to report the candidate resource set, the terminal device initializes the candidate resource set, and the candidate resource set includes the candidate resources in the resource selection window 10. Any candidate resource is denoted as R(x,y).

[0164] Optionally, the terminal device determines a transmission beam for data transmission. Optionally, the terminal device determines a corresponding transmission beam based on a set of candidate resources. Optionally, the terminal device determines a transmission beam corresponding to a candidate resource R(x,y). In time slot t mOn resource 1, the terminal device uses a receiving beam to detect the side control information. If the receiving beam covers the above-determined transmitting beam, the terminal device subtracts the fifth value from the priority value indicated by the side control information to obtain the priority value of the first priority. If the priority value of the priority indicated by the side control information subtracted from the fifth value is less than the minimum value of the priority value, the priority value of the first priority is the minimum value of the above priority values, that is, the first priority is the highest priority. The terminal device determines the RSRP threshold in the RSRP threshold table according to the first priority and the priority of the terminal device data transmission. The terminal device measures the RSRP of the PSCCH carrying the side control information or the PSSCH scheduled by the PSCCH (that is, the PSCCH on resource 1 or the PSSCH scheduled by the PSCCH). If the measured RSRP is greater than the RSRP threshold, and the resource determined according to the side control information overlaps with the resource corresponding to R(x,y), R(x,y) is excluded from the candidate resource set.

[0165] Optionally, the terminal device determines a transmission beam for data transmission. Optionally, the terminal device determines a corresponding transmission beam based on a set of candidate resources. Optionally, the terminal device determines a transmission beam corresponding to a candidate resource R(x,y). In time slot t m On resource 1, the terminal device uses a receiving beam to detect the side control information. If the receiving beam does not cover the transmitting beam determined above, the terminal device adds the sixth value to the priority value of the priority indicated by the side control information to obtain the priority value of the second priority. If the priority value of the priority indicated by the side control information plus the sixth value is greater than the maximum priority value, the priority value of the second priority is the maximum value of the above priority values, that is, the second priority is the lowest priority. The terminal device determines the RSRP threshold in the RSRP threshold table according to the second priority and the priority of the terminal device data transmission. The terminal device measures the RSRP of the PSCCH carrying the side control information or the PSSCH scheduled by the PSCCH (that is, the PSCCH on resource 1 or the PSSCH scheduled by the PSCCH). If the measured RSRP is greater than the RSRP threshold, and the resource determined according to the side control information overlaps with the resource corresponding to R(x,y), R(x,y) is excluded from the candidate resource set.

[0166] In the above embodiment, the terminal device determines the priority used for resource exclusion based on the coverage or correspondence between the spatial transmission filter used for receiving the side control information and the spatial transmission filter used for sending; for example, in the case of coverage or correspondence, the above priority can be higher; in the case of no coverage or no correspondence, the above priority can be lower, thereby fully considering the reference value of the side control information received using the spatial transmission filter for the resource exclusion process, and improving the accuracy of resource exclusion.

[0167] To sum up, the technical solution provided by the embodiment of the present application combines the spatial transmission filter used to receive side control information with the resource selection mechanism, and excludes resources based on the side control information received using the spatial transmission filter, thereby providing a side transmission resource exclusion and selection mechanism suitable for high-frequency communications, which helps to avoid resource conflicts between terminal devices operating at high frequencies and improve communication reliability.
