[0040] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0041] The network architecture and business scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.
[0042] Please refer to Figure 1, which shows a schematic diagram of a network architecture provided in one embodiment of this application. The network architecture may include: a core network 11, an access network 12, and terminal devices 13.
[0043] Core network 11 includes several core network devices. The main functions of these core network devices are to provide user connectivity, manage users, and carry out service delivery, acting as the interface to external networks. For example, the core network of a 5G (5th Generation) NR (New Radio) system may include devices such as AMF (Access and Mobility Management Function), UPF (User Plane Function), and SMF (Session Management Function).
[0044] Access network 12 includes several access network devices 14. In a 5G NR system, the access network can be referred to as NG-RAN (New Generation-Radio Access Network). Access network device 14 is a device deployed in access network 12 to provide wireless communication functionality to terminal device 13. Access network device 14 can include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different wireless access technologies, the names of devices with access network device functionality may differ; for example, in a 5G NR system, they are called gNodeB or gNB. As communication technologies evolve, the name "access network device" may change. For ease of description, in this embodiment, the aforementioned devices providing wireless communication functionality to terminal device 13 are collectively referred to as access network devices.
[0045] The number of terminal devices 13 is typically multiple, with one or more terminal devices 13 distributed within the cell managed by each access network device 14. Terminal devices 13 may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE), mobile stations (MS), etc. For ease of description, the devices mentioned above are collectively referred to as terminal devices. Access network device 14 communicates with core network devices via some over-the-air technology, such as the NG interface in a 5G NR system. Access network device 14 and terminal devices 13 communicate with each other via some over-the-air technology, such as the Uu interface. In the embodiments of this application, "terminal device" can also be referred to as UE; both have the same meaning.
[0046] Terminal devices 13 (e.g., vehicle-mounted devices and other devices such as other vehicle-mounted devices, mobile phones, RSUs (Road Side Units)) can communicate with each other through a direct communication interface (such as a PC5 interface). Correspondingly, the communication link established based on this direct communication interface can be called a direct link or SL. SL transmission refers to direct data transmission between terminal devices via 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 latency and low overhead, making it suitable for communication between two geographically close terminal devices (such as vehicle-mounted devices and other geographically close peripheral devices). It should be noted that Figure 1 only uses vehicle-to-vehicle communication in a V2X (vehicle to everything) scenario as an example; SL technology can be applied to various scenarios where terminal devices communicate directly. In other words, the terminal device in this application refers to any device that uses SL technology for communication.
[0047] The "5G NR system" in this application embodiment can 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 this application embodiment can be applied to 5G NR systems, as well as subsequent evolution systems of 5G NR systems.
[0048] Before introducing the technical solution of this application, some related technical knowledge involved in this application will be introduced and explained. The following related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.
[0049] 1.SL transmission
[0050] Regarding SL transmission, 3GPP defines two transmission modes: Mode A and Mode B.
[0051] 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 single transmission or semi-static transmission to the terminal device.
[0052] Mode B: The terminal device selects transmission resources from the resource pool to transmit communication data. Specifically, the terminal device can select transmission resources from the resource pool by listening or by randomly selecting resources.
[0053] The following section mainly introduces the method of terminal devices autonomously selecting resources in SL communication in the NR V2X system (i.e., mode B mentioned above).
[0054] 2. NR V2X Physical Layer Structure
[0055] 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 the AGC (Automatic Gain Control) symbol. When the SL UE receives data, it can adjust the received power in this symbol to a power suitable for demodulation. When the SL UE transmits data, it repeats the content of the next symbol after 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 third sidelink control information. The PSCCH and PSSCH are transmitted in the same time slot. The aforementioned first and third 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 resource sniffing related fields, facilitating resource exclusion and selection by other terminal devices after decoding. In addition to data, the PSSCH also carries third-sidelink control information, which mainly includes fields related to data demodulation, facilitating demodulation of data in the PSSCH by other terminal devices. Within a given time slot, there may also be a symbol corresponding to the PSFCH (Physical Sidelink Feedback Channel), used to transmit HARQ feedback information. Depending on the resource pool configuration, the symbol corresponding to the PSFCH can appear once every 1, 2, or 4 time slots. When a time slot lacks a symbol corresponding to the PSFCH, for example, the GAP symbol between the PSSCH and PSFCH in Figure 2, the AGC used to receive the PSFCH, and the PSFCH symbol are all used to carry the PSSCH. Typically, the last symbol in a time slot is the GP (Guard Period) symbol, i.e., the GAP. In other words, the symbol following the last symbol carrying the PSSCH or PSFCH is the GP symbol. The SL UE performs transmit / receive switching within the GP symbol but does not transmit data. When PSFCH resources exist in a time slot, GP symbols also exist between the symbols of PSSCH and PSFCH. This is because the UE may transmit on PSSCH and receive on PSFCH, requiring GP symbols for transmit / receive conversion.
[0056] 3. Resource reservation in NR V2X
[0057] In NR V2X systems, under Mode B, the terminal device independently selects transmission resources to send data. Resource reservation is a prerequisite for resource selection.
[0058] Resource reservation refers to the process by which a terminal device reserves resources for future use by sending the first sideline control information in the PSCCH. In NR V2X systems, resource reservation within a TB (Transport Block) and resource reservation between TBs are both supported.
[0059] As shown in Figure 3, the terminal device sends the first sideline control information, using the "Time resource assignment" and "Frequency resource assignment" fields to indicate the N time-frequency resources (including those used for the current transmission) of the current TB. N ≤ Nmax, and in NR V2X, Nmax equals 2 or 3. Simultaneously, the N indicated time-frequency resources should be distributed across W time slots. In NR V2X, W equals 32. For example, in TB1 shown in Figure 3, the terminal device sends the first sideline control information in the PSCCH while simultaneously sending the initial transmission data in the PSSCH, using the above two fields to indicate the time-frequency resource locations for the initial transmission and retransmission 1 (i.e., N = 2 at this time), thus reserving time-frequency resources for retransmission 1. Furthermore, the initial transmission and retransmission 1 are distributed across 32 time slots in the time domain. Similarly, in TB1 shown in Figure 3, the terminal device uses the first sideline control information sent in the PSCCH of retransmission 1 to indicate the time and frequency resource locations of retransmission 1 and retransmission 2. Retransmission 1 and retransmission 2 are distributed in 32 time slots in the time domain.
[0060] Simultaneously, 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 and frequency resource positions of the initial transmission and retransmission 1 of TB1, denoted as {(t1,f1),(t2,f2)}. Here, t1 and t2 represent the time domain positions of the resources for the initial transmission and retransmission 1 of TB1, and f1 and f2 represent the corresponding frequency domain positions. If the value of the "Resource reservation period" field in the first sidelink control information is 100 milliseconds, then the SCI (Sidelink Control Information) simultaneously indicates the time and frequency resources {(t1+100,f1),(t2+100,f2)}, which are used for the transmission of the initial transmission and retransmission 1 of TB2. Similarly, the first sideline control information sent in TB1 retransmission 1 also reserves time and frequency resources for TB2 retransmission 1 and retransmission 2 using the "Resource reservation period" field. In NR V2X, the possible values for 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 compared to LTE (Long Term Evaluation) V2X. However, only e values are configured in each resource pool, and the terminal device determines the possible values to use based on the resource pool it uses. Let the e values in the resource pool configuration be the resource reservation period set M, where, for example, e is less than or equal to 16.
[0061] Furthermore, through network configuration or pre-configuration, the aforementioned inter-TB reservations can be activated or deactivated on a resource pool basis. When activating inter-TB reservations, the first sideline control information includes a "Resource reservation period" field. When deactivating inter-TB reservations, the first sideline control information does not include the "Resource reservation period" field. When activating inter-TB reservations, generally, before triggering resource reselection, the value of the "Resource reservation period" field used by the terminal device, i.e., the resource reservation period, remains unchanged. Each time the terminal device sends a first sideline control message, it uses the "Resource reservation period" field to reserve resources for the next period for the transmission of another TB, thereby achieving periodic semi-persistent transmission.
[0062] When the terminal device operates in Mode B, it can listen to the PSCCH sent by other terminal devices to obtain the first sideline control information sent by those devices, thereby determining the resources reserved by them. When selecting resources, the terminal device will exclude resources reserved by other terminal devices to avoid resource collisions.
[0063] 4. Resource selection method for NR V2X eavesdropping
[0064] In the NR V2X system, under Mode B mentioned above, the terminal device needs to select resources itself.
[0065] 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 in which the higher layer triggers the physical layer to report the candidate resource set. 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, 120 kHz, T proc,1 There are 3, 5, 9, and 17 time slots. T 2min <= T2 <= the remaining latency budget of the service, T 2min The set of values is {1, 5, 10, 20} * 2 μ There are several time slots, where μ = 0, 1, 2, 3 corresponds to subcarrier spacings of 15, 30, 60, and 120 kHz. The terminal device determines T from this set of values based on the priority of its data to be transmitted. 2min For example, when the subcarrier spacing is 15kHz, the terminal device determines T from the set {1,5,10,20} based on the priority of its own data to be transmitted. 2min When T 2minWhen T2 is greater than or equal to the remaining latency budget of the service, then T2 equals the remaining latency budget of the service. The remaining latency budget is the difference between the required latency of the data at the corresponding time and the current time. For example, if a data packet arrives in time slot n with a latency requirement of 50 milliseconds, assuming a time slot is 1 millisecond, if the current time is time slot n, then the remaining latency budget is 50 milliseconds; if the current time is time slot n+20, then the remaining latency budget is 30 milliseconds.
[0066] Terminal devices from n-T0 to nT proc,0 Conduct resource snooping (excluding nT) proc,0 The value of T0 is 100 or 1100 milliseconds. When the subcarrier spacing is 15, 30, 60, or 120 kHz, T... proc,0 There are 1, 1, 2, and 4 time slots. Optionally, the terminal device listens for resources within the time slots belonging to its resource pool within the resource listening window. Optionally, the terminal device listens for the first sideline control information sent by other terminal devices in each time slot (except for its own transmission time slot). When resource selection or reselection is triggered in time slot n, the terminal device uses n-T0 to nT. proc,0 Results of resource eavesdropping.
[0067] Step 1: The terminal device uses all available resources belonging to its resource pool within 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 and time domain positions of the resource, respectively. Let M be the initial number of resources in set A. total The terminal device excludes resources from resource set A based on the unlistened time slots within resource listening window 20 (Step 1-1) and / or the resource listening results within 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 slots determined in Step 1-1 based on the unlistened time slots or the resources determined in Step 1-2 based on the first side-line control information detected. If they overlap, resource R(x,y) is excluded from resource set A.
[0068] Step 1-1: If the terminal device is in time slot t within the resource listening window of 20 m If data is sent without listening, the terminal device will respond according to time slot t. m For each allowed resource reservation period in the resource pool used by the terminal device, Q time slots are determined with that resource reservation period as the interval. If these Q time slots overlap with resource R(x,y) or a series of periodic resources corresponding to resource R(x,y), then resource R(x,y) is excluded from resource set A. The above Q = 1 or (Represents rounding up). Tscal equals 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 resource R(x,y) is R(x,y+j*Ptxlg), j=0,1,2,…,Cresel-1. Where Cresel is related to the random count value generated by the terminal device, and Ptxlg is the number of logical time slots after Ptx is converted. Ptx is the resource reservation period of the terminal device. For example, in sub-figure (a) of Figure 4, Cresel is 3, which represents 3 periodic resources (including R(x,y)) corresponding to resource R(x,y).
[0069] For example, in subgraph (a) of Figure 4, the terminal device in time slot t m Without listening in, resources are excluded sequentially according to each resource reservation period set M in the resource pool configuration. For a certain resource reservation period 1, assuming the Q value is calculated to be 2, the corresponding Q time slots are shown in sub-figure (a) of Figure 4 from time slot t. m The mapping is based on the next two time slots marked with horizontal shading, with a resource reservation period of 1 as the interval. For a certain resource reservation period of 2, assuming the Q value is calculated as Q = 1, the corresponding Q time slots are shown in subgraph (a) of Figure 4, starting from time slot t. m The time slot mapped to the next dotted shaded marker at intervals of 2 resource reservation periods.
[0070] The terminal device will determine whether the Q time slots corresponding to each reserved period overlap with resource R(x,y) or a series of periodic resources corresponding to resource R(x,y). If they overlap, resource R(x,y) will be excluded from resource set A.
[0071] Optionally, when the resource pool used by the terminal device deactivates the reservation between TBs, the terminal device may not perform Step 1-1 above.
[0072] Optionally, after Step 1-1 is executed, if the remaining resources in resource set A are less than M... total If *X is selected, the resource set A will be initialized with all available resources belonging to the resource pool used by the terminal device within the resource selection window 10, and then Step 1-2 will be executed.
[0073] Step 1-2: If the terminal device is in time slot t of resource listening window 20 mThe internal detector listens to the first sidelink control information transmitted in the PSCCH and measures 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 transmitted in the same time slot as the PSCCH).
[0074] If the measured SL-RSRP is greater than the SL-RSRP threshold, and the first sideline control information received by the terminal device contains the "Resource reservation period" field, then the terminal device will determine the time slot t. m The terminal device determines Q time slots based on the resource reservation period carried in the first sideline control information it detects, using this resource reservation period as the interval. The terminal device assumes that it also received the same first sideline control information in these Q time slots. The terminal device will then determine the time slot t... m The received first-side control information and the Q assumed received first-side control information are checked for overlap between the resources indicated in the "Time resource assignment" and "Frequency resource assignment" fields and resource R(x,y) or a series of periodic resources corresponding to resource R(x,y). If they overlap, the corresponding resource R(x,y) is excluded from set A. The above Q=1 or (Represents rounding up). Tscal equals the value of T2 converted to milliseconds. Prx is the resource reservation period carried in the first side-line control information detected. Optionally, a series of periodic resources corresponding to resource R(x,y) is R(x,y+j*Ptxlg), j=0,1,2,…,Cresel-1. Where Cresel is related to the random count value generated by the terminal device, and Ptxlg is the number of logical time slots after Ptx is converted. Ptx is the resource reservation period of the terminal device. For example, in sub-figure (b) of Figure 4, Cresel is 3, which means 3 periodic resources (including R(x,y)) corresponding to resource R(x,y).
[0075] For example, in subgraph (b) of Figure 4, 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 sideline control information in the PSCCH is detected on resource E(v,m). The resource reservation period in this first sideline control information is Prx. Assuming the Q value is calculated to be 1, the terminal device will assume that in time slot t m+Prxlg The terminal device also received the same first-side control information. The terminal device will determine the time slot t.m The first sideline control information received and the assumption in time slot t m+Prxlg The "Time resource assignment" and "Frequency resource assignment" fields of the received first sideline control information indicate whether resources 1, 2, 3, 4, 5, and 6 overlap with resource R(x,y) or a series of periodic resources corresponding to resource R(x,y). If they overlap and satisfy the RSRP condition, resource R(x,y) is excluded from resource set A.
[0076] If the SL-RSRP measured by the terminal device is greater than the SL-RSRP threshold, and the first sideline control information received by the terminal device does not contain the "Resource reservation period" field, then the terminal device only determines the time slot t. m The "Time resource assignment" and "Frequency resource assignment" fields of the received first sideline control information indicate whether the resource overlaps with resource R(x,y) or a series of resources corresponding to resource R(x,y). If they overlap, resource R(x,y) is excluded from resource set A.
[0077] For example, in subgraph (b) of Figure 4, 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 sideline control information in the PSCCH is detected on 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 sideline control information overlap with resource R(x,y) or a series of periodic resources corresponding to resource R(x,y). If they overlap and the RSRP condition is met, resource R(x,y) is excluded from resource set A.
[0078] If, after the above resource exclusions, the remaining resources in resource set A are less than M... total If *X, the SL-RSRP threshold is raised by 3dB, and Step 1 is executed again. The physical layer reports the resource set A, after excluding resources, as a candidate resource set to the higher layer.
[0079] Step 2: The higher-level management randomly selects resources from the reported candidate resource set to send data. That is, the terminal device randomly selects resources from the candidate resource set to send data.
[0080] It is important to note that:
[0081] (1) The RSRP threshold mentioned above is determined by the priority P1 carried in the PSCCH detected by the terminal device and the priority P2 of the data to be sent by the terminal device. (2) Whether the terminal device compares the measured PSCCH-RSRP or the PSSCH-RSRP scheduled by the PSCCH 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 configuration or pre-configured.
[0082] (3) X as described above, where X may take the values {20%, 35%, 50%}. The configuration of the resource pool used by the terminal device includes the correspondence between priorities and the above possible values. The terminal device determines the value of X based on the priority of the data to be sent and this correspondence. The resource pool configuration can be configured by the network or pre-configured.
[0083] The above description describes one type of SL communication in NR-V2X, where the terminal device autonomously selects transmission resources through resource listening and transmits data on the side link. This SL communication method can also be applied to various SL communication applications, such as direct communication between handheld terminals and direct communication between pedestrians and vehicles.
[0084] 5. LTX V2X Physical Layer Structure
[0085] The physical layer structure of SL communication in an LTE V2X system is shown in Figure 5. The PSCCH is used to carry second-sideline control information, and the PSSCH is used to carry data. Both the PSCCH and PSSCH are transmitted in the same subframe. The first symbol in the subframe is the AGC symbol. When the SL UE is receiving data, it can adjust the receiving circuitry in this symbol to suit its parameters. When the SL UE is transmitting data, it repeats the content of the symbol following the AGC symbol.
[0086] In LTE V2X, the PSCCH and PSSCH can be continuous or discontinuous in the frequency domain.
[0087] The aforementioned second-side control information is carried in the PSCCH, mainly containing resource listening-related fields, which facilitates resource exclusion and selection by other terminal devices after decoding.
[0088] Furthermore, the resource reservation and snooping-based resource selection methods in the LTE V2X system are similar to those in the NR V2X system, and will not be elaborated upon further here. Only a brief introduction is provided: In the LTE V2X system, the first to third information fields in the second-side row control information indicate retransmission resources within the same data unit (TB). Optionally, the fourth information field in the second-side row control information also indicates transmission resources for another TB. Specifically, the first information field refers to the frequency resource location of the initial transmission and retransmission in the second-side row control information; the second information field refers to the time gap between initial transmission and retransmission in the second-side row control information; the third information field refers to the retransmission index in the second-side row control information; and the fourth information field refers to the resource reservation in the second-side row control information.
[0089] 6. HARQ Feedback and PSFCH Resources
[0090] HARQ retransmission: For transmissions sent by the sender, the receiver can send either an ACK or NACK response to the sender, depending on whether the reception was successful. ACK indicates successful reception, and NACK indicates reception failure. The receiver sends HARQ feedback to the sender via PSFCH.
[0091] PSFCH resources are configured for each resource pool. In NR-V2X, there are three configurations for PSFCH resources: N=1, N=2, and N=4. As shown in Figure 6, N=1 means that PSFCH resources are configured for every time slot in the resource pool; N=2 means that PSFCH resources are configured for every two time slots in the resource pool; and N=4 means that PSFCH resources are configured for every four time slots in the resource pool. More specifically, within a time slot, the PSFCH resource is configured in the second-to-last symbol among the symbols available for SL transmission within that time slot (note that in the frequency domain example in the figure, PSFCH resources are configured for the entire frequency domain; optionally, only a portion of the PRBs (Physical Resource Blocks) can be configured as available PSFCH resources). When UE1 sends data to UE2 in time slot t, the HARQ feedback from UE2 to UE1 for this data transmission occurs in time slot t+a. Where 'a' is greater than or equal to 'k', and time slot 't+a' contains PSFCH resources, k in NR-V2X takes 2 or 3 time slots. For example, in Figure 6, assuming N=4 and k=2, if UE1 sends data to UE2 in time slot 1, then 't+a' is time slot 4, and UE2 performs HARQ feedback to UE1 in time slot 4. If UE1 sends data to UE2 in time slot 3, then 't+a' is time slot 8, and UE2 performs HARQ feedback to UE1 in time slot 8. Therefore, the time domain location of the PSFCH resource used for feedback is determined based on the time domain location of the corresponding PSSCH for the transmitted data. Similarly, the frequency domain location of the PSFCH resource is also determined based on the frequency domain resource location of the PSSCH. For example, there is a correspondence between the sub-channel corresponding to the PSSCH and the PRB corresponding to the PSFCH, and the receiver can determine the PRB corresponding to the PSFCH based on the sub-channel corresponding to the PSSCH. It should be noted that, according to the above design, if resource collisions occur between the PSSCHs of two transmitters (i.e., both transmitters use the same time slot and the same sub-channel for transmission), resource collisions between the two PSFCHs will inevitably occur. To solve this problem, the receiver will perform a modulo operation on the PRB corresponding to the PSFCH or on the code domain resources of the PRB corresponding to the PSFCH, based on the source ID of the transmitter, so that the PSSCHs of different transmitters are ultimately mapped to different frequency domain resources or code domain resources used for PSFCH transmission.
[0092] 7. Dynamic spectrum sharing
[0093] Both LTE SL and NR SL introduce the concept of resource pools, meaning that SL transmissions occur within the SL's resource pool. One purpose of introducing resource pools is to avoid resource conflicts between uplink and sidelink transmissions. Specifically, when scheduling uplink transmissions for a UE, the base station will not schedule uplink transmissions within the configured SL resource pool. This semi-static configuration of resource pools isolates the time-frequency resource ranges of uplink and sidelink transmissions.
[0094] The related discussions have already supported scenarios where LTE SL UEs and NR SL UEs dynamically share resource pools. As shown in Figure 7, the NR SL UE is a dual-mode terminal, including an LTE SL module and an NR SL module. The LTE SL module can collect LTE SL SCIs sent by other LTE SL UEs and pass the listening results to the NR SL module inside the UE. The NR SL module performs resource exclusion based on the LTE SL SCIs detected by the LTE SL module, and selects the transmission resources of the NR SL from the resource set after resource exclusion, thereby avoiding resource conflicts between the NR SL UE and the LTE SL UE.
[0095] As described above, currently only semi-static spectrum sharing between UL and SL is supported through resource pool configuration. This application considers supporting dynamic spectrum sharing between UL and SL in future networks. Furthermore, in future networks, SL can refer to deployed LTE SL or deployed NR SL. Since the coexistence of LTE SL and NR SL within the same resource pool is already supported, SL can also refer to simultaneously deployed LTE SL and NR SL. Therefore, this application also discusses dynamic spectrum sharing between UL and LTE SL and / or NR SL in future networks.
[0096] Please refer to Figure 8, which shows a flowchart of an information reporting method provided in one embodiment of this application. This method can be applied to the network architecture shown in Figure 1. The method may include the following step 810.
[0097] Step 810: The first terminal device sends first information to the network device. The first information is used to report the first transmission resource and / or the second transmission resource. The first transmission resource is the transmission resource determined according to the first sideline control information, and the second transmission resource is the transmission resource determined according to the second sideline control information. The first sideline control information and the second sideline control information are sideline control information in two different communication systems.
[0098] Accordingly, the network device receives the first information sent by the first terminal device.
[0099] In some embodiments, the first terminal device can be any terminal device.
[0100] In some embodiments, the first sidelink control information is sidelink control information in a first communication system. In some embodiments, the first sidelink control information is sidelink control information in a first communication system received by a first terminal device. In some embodiments, the first communication system is an NR or 5G system.
[0101] In some embodiments, the second sideline control information is sideline control information in a second communication system. In some embodiments, the second sideline control information is sideline control information in a second communication system received by the first terminal device. In some embodiments, the second communication system is an LTE system, a 4G system, or an E-UTRA (Evolved Universal Terrestrial Radio Access) system.
[0102] In some embodiments, the first lateral control information is lateral control information in a first communication system, and the second lateral control information is lateral control information in a second communication system, wherein the first communication system and the second communication system are two different communication systems.
[0103] For example, the first communication system is an NR system or a 5G system, and the second communication system is an LTE system, a 4G system, or an E-UTRA system. The first sideline control information is sideline control information in the NR system or the 5G system, and the second sideline control information is sideline control information in the LTE system, the 4G system, or the E-UTRA system. For example, the first sideline control information is SCI format 1-A, and the second sideline control information is SCI format 1.

[0105] In some embodiments, as described above, the first sideline control information is carried in the PSCCH and mainly includes fields related to resource snooping, facilitating resource exclusion and selection by other terminal devices after decoding. The first sideline control information may include "Time resource assignment" and "Frequency resource assignment" fields, and optionally, it may also include a "Resource reservation period" field.
[0106] In some embodiments, the transmission resources indicated by the first sideline control information include the transmission resources indicated by the "Time resource assignment" and "Frequency resource assignment" fields in the first sideline control information.
[0107] In some embodiments, the periodic resources corresponding to the transmission resources indicated by the first sideline control information include the transmission resources indicated by the "Time resource assignment" and "Frequency resource assignment" fields in the first sideline control information, as well as the periodic resources corresponding to the aforementioned transmission resources indicated by the "Resource reservation period" field.
[0108] In some embodiments, the PSFCH resource corresponding to the transmission resource indicated by the first sideline control information refers to the resource used for transmitting sideline feedback information.
[0109] In some embodiments, the first terminal device obtains remaining resources after resource exclusion. The first transmission resources include the remaining resources. In some embodiments, resource exclusion includes resource exclusion based on first sideline control information. Optionally, it also includes resource exclusion based on second sideline control information, that is, resource exclusion includes resource exclusion based on both first and second sideline control information. The process of resource exclusion can be found in the above description and will not be repeated here.
[0110] In some embodiments, after the first terminal device performs resource exclusion, it obtains remaining resources and determines the transmission resources of the first terminal device from the remaining resources. The first transmission resources include the transmission resources of the first terminal device determined after resource exclusion. Similarly, the resource exclusion here includes resource exclusion based on first sideline control information. Optionally, it also includes resource exclusion based on second sideline control information.
[0111] In some embodiments, the second transmission resource includes at least one of the following: transmission resources indicated by the second sideline control information, periodic resources corresponding to the transmission resources indicated by the second sideline control information, remaining resources after resource exclusion, and transmission resources of the first terminal device determined after resource exclusion; wherein, resource exclusion includes resource exclusion based on the second sideline control information.
[0112] In some embodiments, as described above, the second sideline control information is carried in the PSCCH and mainly includes resource snooping related fields, facilitating resource exclusion and selection by other terminal devices after decoding. The second sideline control information may include the first to third information fields described above, and optionally also include a fourth information field. For a description of each of the above information fields, please refer to the above text.
[0113] In some embodiments, the transmission resources indicated by the second sideline control information include the transmission resources indicated by the first to third information fields in the second sideline control information.
[0114] In some embodiments, the periodic resources corresponding to the transmission resources indicated by the second sideline control information include the transmission resources indicated by the first to third information fields in the second sideline control information, and the periodic resources corresponding to the aforementioned transmission resources indicated by the fourth information field.
[0115] In some embodiments, the first terminal device obtains remaining resources after resource exclusion. The second transmission resources include these remaining resources. In some embodiments, resource exclusion includes resource exclusion based on second sideline control information. Optionally, it also includes resource exclusion based on first sideline control information; that is, resource exclusion includes resource exclusion based on both second sideline control information and first sideline control information. The process of resource exclusion can be found in the above description and will not be repeated here.
[0116] In some embodiments, after the first terminal device performs resource exclusion, it obtains remaining resources and determines the transmission resources of the first terminal device from the remaining resources. The second transmission resources include the transmission resources of the first terminal device determined after resource exclusion. Similarly, resource exclusion here includes resource exclusion based on second sideline control information. Optionally, it also includes resource exclusion based on first sideline control information.
[0117] In some embodiments, the first transmission resource and / or the second transmission resource are reported when a first condition is met. That is, when the first condition is met, the first terminal device sends first information to the network device to report the first transmission resource and / or the second transmission resource to the network device through the first information.
[0118] In some embodiments, the first condition includes at least one of the following: a periodic condition, receiving a trigger command from a network device, or the CBR (Channel Busy Ratio) measured by the first terminal device being greater than or equal to a CBR threshold.
[0119] The periodic condition refers to the first terminal device's ability to periodically report the first transmission resource and / or the second transmission resource. Alternatively, the first terminal device may also report the first transmission resource and / or the second transmission resource to the network device upon receiving a trigger command from the network device. Or, the first terminal device may measure the CBR (Cost-Based Breakdown) and report the first transmission resource and / or the second transmission resource to the network device if the CBR is greater than or equal to the CBR threshold. The CBR threshold may be configured by the network device, pre-configured, predefined by a standard, or depend on the implementation of the first terminal device.
[0120] In some embodiments, as shown in FIG8, step 810 is followed by step 820.
[0121] Step 820: The network device determines the third transmission resource used for uplink transmission based on the first information.
[0122] The network device determines a third transmission resource based on the first transmission resource and / or the second transmission resource reported by the first terminal device. This third transmission resource may be the transmission resource used for uplink transmission by the first terminal device, or it may be the transmission resource used for uplink transmission by another terminal device other than the first terminal device.
[0123] In some embodiments, the third transmission resource is the transmission resource used by the first terminal device for uplink transmission. In this case, as shown in FIG9, the above step 820 is followed by the following step 830.
[0124] Step 830: The network device sends second information to the first terminal device, the second information being used to indicate the third transmission resource.
[0125] Accordingly, the first terminal device receives the second information sent by the network device.
[0126] When the third transmission resource is the transmission resource used by the first terminal device for uplink transmission, the network device can send second information to the first terminal device to indicate the third transmission resource to the first terminal device so that the first terminal device can use the third transmission resource for uplink transmission.
[0127] In some embodiments, the second information includes indication information of the time-domain and / or frequency-domain location of the third transmission resource.
[0128] In some embodiments, as shown in FIG9, step 830 is followed by step 840.
[0129] Step 840: The first terminal device uses the third transmission resource to perform uplink transmission.
[0130] Accordingly, the network device receives the uplink transmission from the first terminal device on the third transmission resource.
[0131] In some embodiments, the third transmission resource is the transmission resource used for uplink transmission by the second terminal device, which is a different terminal device from the first terminal device. In this case, the network device can send second information to the second terminal device, which indicates the third transmission resource. After receiving the second information sent by the network device, the second terminal device can use the third transmission resource for uplink transmission.
[0132] The third transmission resource will now be explained.
[0133] In some embodiments, the third transmission resource does not overlap with the first transmission resource or does not overlap in the time domain. For example, when the first information is used to report the first transmission resource, the network device determines the third transmission resource based on the first transmission resource, wherein the third transmission resource does not overlap with the first transmission resource or does not overlap in the time domain. For example, the network device preferentially schedules resources that do not overlap with the first transmission resource or do not overlap in the time domain as the third transmission resource. For example, "no overlap" means that there is no overlap in both the time and frequency domains.
[0134] In some embodiments, when the first information is used to report the first transmission resource, if the first transmission resource includes at least one of the following: the transmission resource indicated by the first sideline control information, the periodic resource corresponding to the transmission resource indicated by the first sideline control information, the PSFCH resource corresponding to the transmission resource indicated by the first sideline control information, and the transmission resource of the first terminal device determined after resource exclusion (wherein, resource exclusion includes resource exclusion based on the first sideline control information), the third transmission resource does not overlap with the first transmission resource or does not overlap in the time domain.
[0135] In some embodiments, the third transmission resource is a resource included in the first transmission resource. From the perspective of the network device, the third transmission resource is determined from the resources included in the first transmission resource. For example, when the first information is used to report the first transmission resource, the network device preferentially determines or schedules the third transmission resource from the resources included in the first transmission resource.
[0136] In some embodiments, when the first information is used to report the first transmission resource, if the first transmission resource is the remaining resource after resource exclusion (wherein, resource exclusion includes resource exclusion based on the first sideline control information), the third transmission resource is determined from the resources contained in the first transmission resource.
[0137] In some embodiments, the third transmission resource does not overlap with the second transmission resource or does not overlap in the temporal domain. For example, when the first information is used to report the second transmission resource, the network device determines the third transmission resource based on the second transmission resource, wherein the third transmission resource does not overlap with the second transmission resource or does not overlap in the temporal domain. For example, the network device preferentially schedules the resource that does not overlap with the second transmission resource or does not overlap in the temporal domain as the third transmission resource.
[0138] In some embodiments, when the first information is used to report the second transmission resource, if the second transmission resource includes at least one of the following: the transmission resource indicated by the second sideline control information, the periodic resource corresponding to the transmission resource indicated by the second sideline control information, and the transmission resource of the first terminal device determined after resource exclusion (wherein, resource exclusion includes resource exclusion based on the second sideline control information), the third transmission resource does not overlap with the second transmission resource or does not overlap in the time domain.
[0139] In some embodiments, the third transmission resource is a resource included in the second transmission resource. From the perspective of the network device, the third transmission resource is determined from the resources included in the second transmission resource. For example, when the first information is used to report the second transmission resource, the network device preferentially determines or schedules the third transmission resource from the resources included in the second transmission resource.
[0140] In some embodiments, when the first information is used to report the second transmission resource, if the second transmission resource is the remaining resource after resource exclusion (wherein, resource exclusion includes resource exclusion according to the second sideline control information), the third transmission resource is determined from the resources contained in the second transmission resource.
[0141] In some embodiments, the third transmission resource does not overlap with the first transmission resource or does not overlap in the time domain, and the third transmission resource does not overlap with the second transmission resource or does not overlap in the time domain. For example, when the first information is used to report the first and second transmission resources, the network device determines the third transmission resource based on the first and second transmission resources, wherein the third transmission resource does not overlap with the first transmission resource or does not overlap in the time domain, and also does not overlap with the second transmission resource or does not overlap in the time domain. For example, the third transmission resource does not overlap with the first transmission resource or does not overlap in the time domain, and also does not overlap in the time domain with the second transmission resource. For example, the network device preferentially schedules the resource that does not overlap with the first transmission resource or does not overlap in the time domain, and also does not overlap with the second transmission resource or does not overlap in the time domain, as the third transmission resource.
[0142] In some embodiments, when the first information is used to report the first transmission resource and the second transmission resource, if the first transmission resource includes at least one of the following: the transmission resource indicated by the first sideline control information, the periodic resource corresponding to the transmission resource indicated by the first sideline control information, the PSFCH resource corresponding to the transmission resource indicated by the first sideline control information, and the transmission resource of the first terminal device determined after resource exclusion (wherein, resource exclusion includes resource exclusion based on the first sideline control information), and the second transmission resource includes at least one of the following: the transmission resource indicated by the second sideline control information, the periodic resource corresponding to the transmission resource indicated by the second sideline control information, and the transmission resource of the first terminal device determined after resource exclusion (wherein, resource exclusion includes resource exclusion based on the second sideline control information), and the third transmission resource does not overlap with the first transmission resource or does not overlap in the time domain, and the third transmission resource does not overlap with the second transmission resource or does not overlap in the time domain.
[0143] In some embodiments, the third transmission resource is a resource shared by both the first and second transmission resources. From the perspective of the network device, the third transmission resource is determined from the resources shared by the first and second transmission resources. For example, when the first information is used to report the first and second transmission resources, the network device preferentially determines or schedules the third transmission resource from the resources shared by the first and second transmission resources.
[0144] In some embodiments, when the first information is used to report the first transmission resource and the second transmission resource, if the first transmission resource is the remaining resource after resource exclusion (wherein, resource exclusion includes resource exclusion based on the first sideline control information) and the second transmission resource is the remaining resource after resource exclusion (wherein, resource exclusion includes resource exclusion based on the second sideline control information), the third transmission resource is determined from the resources jointly included by the first transmission resource and the second transmission resource.
[0145] In some embodiments, the temporal starting position of the third transmission resource coincides with the position of the AGC symbol.
[0146] The technical solution provided in this application embodiment reports the transmission resources determined by the side-link control information to the network device through the terminal device, so that the network device can make decisions accordingly, such as scheduling the transmission resources used for uplink transmission, thereby avoiding resource conflicts and increasing spectrum utilization in scenarios that support dynamic spectrum sharing between UL and SL.
[0147] When the terminal device reports the first transmission resource determined by the first sideline control information in the NR or 5G system to the network device, it can avoid resource conflicts and increase spectrum utilization in scenarios that support dynamic spectrum sharing between UL and NR SL.
[0148] When the terminal device reports the second transmission resource determined by the second sideline control information in the LTE or 4G system to the network device, it realizes the avoidance of resource conflicts and the increase of spectrum utilization in the scenario that supports dynamic spectrum sharing between UL and LTE SL.
[0149] When the terminal device reports the first transmission resource determined by the first sideline control information in the NR or 5G system to the network device, and the second transmission resource determined by the second sideline control information in the LTE or 4G system, resource conflicts are avoided and spectrum utilization is increased in scenarios that support dynamic spectrum sharing between UL and NR SL and LTE SL.
[0150] The technical solution of this application will be described and illustrated below through several embodiments.
[0151] Scenario 1: In the scenario where UL and NR SL dynamically share spectrum, the first terminal device reports the first transmission resource.
[0152] As shown in Figure 10, from the perspective of the inside of the first terminal device, the first terminal device includes a first side-link communication module and an uplink / downlink communication module. Exemplarily, the first side-link communication module is an NR SL module, and the uplink / downlink communication module is a Uu module. Exemplarily, the Uu module is a 6G Uu module.
[0153] In some embodiments, the NR SL module listens for first sidelink control information, determines a first transmission resource based on the first sidelink control information, and passes the first transmission resource to the Uu module. The Uu module then reports the first transmission resource to the network device. Optionally, the Uu module of the first terminal device determines the time-frequency location of the third transmission resource according to the instructions of the network device and performs uplink transmission on the third transmission resource. Optionally, the network device may also schedule the third transmission resource for uplink transmission for other terminal devices (e.g., a second terminal device) based on the first transmission resource reported by the first terminal device.
[0154] In some embodiments, the NR SL module of the first terminal device determines the first transmission resource in time slot n1. For example, time slot n1 is determined based on the time when the network device triggers the first terminal device to report the first transmission resource. For instance, if the time when the Uu module receives the trigger signaling from the network device is n, then n1 = n + a, where a includes at least: the time when the Uu module processes the trigger signaling, the time when it sends the trigger signaling to the NR SL module, and the time when the NR SL module receives the trigger signaling. For example, time slot n1 is determined based on the period of the first terminal device reporting the first transmission resource. When the Uu module determines that time slot n is an integer multiple of the period, it sends trigger information to the NR SL module, then n1 = n + a, where a includes at least the time when the Uu module sends the trigger signaling to the NR SL module and the time when the NR SL module receives the trigger signaling.
[0155] The NR SL module determines a first transmission resource based on first sideline control information detected within a resource listening window. For example, the resource listening window is [n1-T]. 10 ,n1-T proc,0 ), for example, T 10 For 100 or 1100 milliseconds, T proc,0 Refer to the above description. For example, T 10 The period for the first terminal device to report the first transmission resource.
[0156] In some embodiments, the first transmission resource includes transmission resources indicated by the detected first sideline control information. For example, resources indicated by the time resource assignment and frequency resource assignment fields. As shown in FIG11, if the NR SL module detects the first sideline control information on resource x, then the first transmission resource includes transmission resources x, y, and z indicated by the first sideline control information. Alternatively, as shown in FIG11, if the NR SL module detects the first sideline control information on resource x, then the first transmission resource includes reserved transmission resources y and z indicated by the first sideline control information.
[0157] In some embodiments, the first transmission resource includes periodic resources corresponding to the transmission resources indicated by the detected first sideline control information. The periodic resources are determined according to the resource reservation period indicated by the first sideline control information, and the periodic resources include the transmission resources indicated by the first sideline control information. For example, in FIG11, if the NR SL module detects the first sideline control information on resource x, then the first transmission resource includes transmission resources x, y, and z indicated by the first sideline control information, and resources j, k, and i with the same frequency domain position as x, y, and z, and whose time domain interval is determined according to the resource reservation period indicated by the first sideline control information, assuming the number of periods is 1. Exemplarily, the number of periods is configured or pre-configured by the network device, predefined by the standard, or depends on the implementation of the first terminal device.
[0158] In some embodiments, the first transmission resource includes the PSFCH resource corresponding to the transmission resource indicated by the detected first sideline control information. For example, in Figure 11, if the NR SL module detects the first sideline control information on resource x, then the first transmission resource includes the PSFCH resources corresponding to transmission resources x, y, and z indicated by the first sideline control information. There is a correspondence between the PSSCH resource and the PSFCH resource. The specific time-frequency resource correspondence can be found in the above description.
[0159] In some embodiments, the first transmission resource includes remaining resources after resource exclusion, which includes resource exclusion based on transmission resources indicated by the detected first sideline control information. For example, the NR SL module determines [n1+T 11 ,n1+T 12 The resource selection window, T 11 and T 12 See T1 and T2 in the NR SL resource selection mechanism above. The NR SL module performs the following steps:
[0160] (1) Initialize all available resources in the resource selection window into a resource set A. Let any resource in resource set A be R(x,y), where x and y represent the frequency domain position and time domain position of the resource, respectively. Let M be the initial number of resources in resource set A. total .
[0161] (2) Eliminate resources based on unlistened time slots.
[0162] (3) Eliminate resources based on the first side control information detected.
[0163] (4) If the number of remaining resources in resource set A is less than X*M total If so, raise the RSRP threshold by 3dB and repeat step (1). X is configured or pre-configured by the network.
[0164] For details of the above steps, please refer to the above description. The first transmission resource includes the remaining resources in resource set A. As shown in Figure 11, assuming that the remaining resources after resource exclusion include resources h and u, then the first transmission resource includes resources h and u.
[0165] In some embodiments, the first transmission resource includes the transmission resources of the first terminal device determined after resource exclusion, which includes resource exclusion based on the transmission resources indicated by the detected first sideline control information. For example, it could be the transmission resources of the determined NR SL module. As shown in Figure 11, assuming the remaining resources in resource set A after resource exclusion include resources h and u, the NR SL module randomly selects a transmission resource from resource set A, selecting resource u. Therefore, the first transmission resource includes resource u. Furthermore, the NR SL module may further determine periodic transmission resources based on its own resource reservation period and the transmission resources determined in resource set A. As shown in Figure 11, assuming the NR SL module determines resource u, the first transmission resource includes resource u and resource v, which has the same frequency domain position as resource u and a time domain interval determined according to the resource reservation period of the NR SL module. Here, it is assumed that the number of periods is 1.
[0166] In some embodiments, the NR SL module sends the measured CBR simultaneously with the first transmission resource sent to the Uu module. For example, CBR is the proportion of sub-channels with an SL RSSI higher than a configured threshold within the measurement window [n1-c, n1-1] out of the total number of sub-channels in the resource pool, where c equals 100 or 100×2. μ Each time slot has a value μ related to the subcarrier spacing. Subcarrier spacings of 15kHz, 30kHz, 60kHz, and 120kHz correspond to μ values of 0, 1, 2, and 3, respectively. If the Uu module determines that the CBR is greater than or equal to a first threshold, it reports the first transmission resource to the network. Otherwise, it does not report the first transmission resource. The first threshold can be configured by the network device, pre-configured, predefined by the standard, or depend on the implementation of the first terminal device.
[0167] In some embodiments, after receiving the first transmission resource reported by the Uu module, the network device schedules the third transmission resource for the first terminal device or the second terminal device.
[0168] Optionally, if the first transmission resource is the transmission resource indicated by the first side-link control information, the network device prioritizes scheduling resources that do not overlap with the first transmission resource or do not overlap in the time domain as the third transmission resource. For example, in Figure 11, if the Uu module reports resources y and z indicated by the first side-link control information, the network device schedules resource h, which does not overlap with resources y and z, as the third transmission resource, or schedules resource f, which does not overlap with resources y and z in the time domain, as the third transmission resource.
[0169] Optionally, if the first transmission resource is a periodic resource corresponding to the transmission resource indicated by the first side-link control information, the network device prioritizes scheduling resources that do not overlap with the first transmission resource or do not overlap in the time domain as the third transmission resource. For example, in Figure 11, the Uu module reports periodic resources corresponding to the resources indicated by the first side-link control information, namely x, y, and z, and j, k, and i. Then, the network device schedules resource h, which does not overlap with the reported resources, as the third transmission resource, or schedules resource f, which does not overlap in the time domain with the reported resources, as the third transmission resource.
[0170] Optionally, if the first transmission resource is the PSFCH resource corresponding to the transmission resource indicated by the first side-link control information, the network device prioritizes scheduling resources that do not overlap with the first transmission resource or do not overlap in the time domain as the third transmission resource. For example, in Figure 11, if the Uu module reports the PSFCH resource corresponding to the resource indicated by the first side-link control information, i.e., the PSFCH resources corresponding to x, y, and z, then the network device schedules resource p, which does not overlap with the reported resource, as the third transmission resource, or schedules resource g, which does not overlap in the time domain with the reported resource, as the third transmission resource.
[0171] Optionally, if the first transmission resource is a remaining resource after resource exclusion, the resource exclusion includes resource exclusion according to the resource indicated by the first side-line control information, and the network device prioritizes scheduling the third transmission resource from the resources included in the first transmission resource reported by the first terminal device. For example, as shown in Figure 11, assuming that the Uu module reports resources h and u included in the resource set A after resource exclusion, the network device prioritizes scheduling h or u as the third transmission resource. Alternatively, it may schedule a portion of the PRB and / or a portion of the OFDM (Orthogonal Frequency Division Multiplexing) symbols in the resources included in resources h and u as the third transmission resource.
[0172] Optionally, if the first transmission resource is the transmission resource of the first terminal device determined after resource exclusion, the resource exclusion includes resource exclusion according to the resource indicated by the first side-channel control information, and the network device prioritizes scheduling resources that do not overlap with the first transmission resource or do not overlap in the time domain as the third transmission resource. For example, when the third transmission resource is scheduled to the first terminal device, the third transmission resource does not overlap in the time domain with the first transmission resource. For example, when the third transmission resource is scheduled to the second terminal device, the third transmission resource does not overlap with the first transmission resource or does not overlap in the time domain. For example, in Figure 11, the Uu module reports transmission resources u and v determined after resource exclusion by the NR SL module. If the third transmission resource is scheduled to the first terminal device, the network device schedules resource f, which does not overlap in the time domain with resources u and v. If the third transmission resource is scheduled to the second terminal device, the network device schedules resource e, which does not overlap in the time domain with resources u and v, or schedules resource f, which does not overlap in the time domain with resources u and v.
[0173] In some embodiments, when a network device schedules a third transmission resource, the starting position of the third transmission resource in the time domain should be consistent with the position of the AGC symbol. For example, in Figure 11, assuming the first symbol of the time slot is the AGC symbol, the scheduled third transmission resource is either h or g, and its starting position is the AGC symbol within the time slot. As another example in Figure 11, when the scheduled third transmission resource is p, the starting symbol of p should be the AGC symbol before the PSFCH resource. Referring to Figure 2, the starting position of the scheduled third transmission resource in the time domain should be located at the first symbol or the 12th symbol in Figure 2.
[0174] Scenario 2: In the scenario where UL and LTE SL dynamically share spectrum, the first terminal device reports the second transmission resource.
[0175] As shown in Figure 12, from the perspective of the first terminal device's internal structure, the first terminal device includes a second side-link communication module and an uplink / downlink communication module. Exemplarily, the second side-link communication module is an LTE SL module, and the uplink / downlink communication module is a Uu module. Exemplarily, the Uu module is a 6G Uu module.
[0176] In some embodiments, the LTE SL module listens for second sidelink control information, determines a second transmission resource based on the second sidelink control information, and passes the second transmission resource to the Uu module. The Uu module then reports the second transmission resource to the network device. Optionally, the Uu module of the first terminal device determines the time-frequency position of the third transmission resource according to the instructions of the network device and performs uplink transmission on the third transmission resource. Optionally, the network device may also schedule the third transmission resource for uplink transmission for other terminal devices (e.g., the second terminal device) based on the second transmission resource reported by the first terminal device.
[0177] In some embodiments, the LTE SL module of the first terminal device determines the second transmission resource in subframe n2. For example, subframe n2 is determined based on the time when the network device triggers the first terminal device to report the second transmission resource. For instance, if the time when the Uu module receives the trigger signaling from the network device is n, then n2 = n + b, where b includes at least: the time when the Uu module processes the trigger signaling, the time when it sends the trigger signaling to the LTE SL module, and the time when the LTE SL module receives the trigger signaling. For example, subframe n2 is determined based on the period of the second transmission resource reported by the first terminal device. When the Uu module determines that time slot n is an integer multiple of the period, it sends trigger information to the LTE SL module, then n2 = n + b, where b includes at least the time when the Uu module sends the trigger signaling to the LTE SL module and the time when the LTE SL module receives the trigger signaling. Optionally, when the subcarrier spacing of the LTE SL module and the Uu module is different, the above-mentioned b also includes the time offset from the time slot to the subframe transition.
[0178] The LTE SL module determines the second transmission resource based on the second sideline control information detected within the resource listening window. For example, the resource listening window is [n2-T]. 20 ,n2), for example, T 20 It is 1000 milliseconds. For example, T... 20 The period for the first terminal device to report the second transmission resource.
[0179] In some embodiments, the second transmission resource includes the transmission resource indicated by the detected second sideline control information. For example, it may be the resource indicated by the first to third information fields. As shown in FIG13, if the LTE SL module detects the second sideline control information on resource x, then the second transmission resource includes transmission resources x and z indicated by the second sideline control information. Alternatively, as shown in FIG13, if the LTE SL module detects the second sideline control information on resource x, then the second transmission resource includes the reserved transmission resource z indicated by the second sideline control information.
[0180] In some embodiments, the second transmission resource includes periodic resources corresponding to the transmission resources indicated by the detected second sideline control information. The periodic resources are determined according to the resource reservation period indicated by the second sideline control information, and the periodic resources include the resources indicated by the second sideline control information. For example, in FIG13, if the LTE SL module detects the second sideline control information on resource x, then the second transmission resource includes transmission resources x and z indicated by the second sideline control information, and resources j and i with the same frequency domain position as x and z, and whose time domain interval is determined according to the resource reservation period indicated by the second sideline control information, assuming the number of periods is 1. Exemplarily, the number of periods is configured or pre-configured by the network device, predefined by the standard, or depends on the implementation of the first terminal device.
[0181] In some embodiments, the second transmission resource includes remaining resources after resource exclusion, which includes resource exclusion based on transmission resources indicated by the detected second sideline control information. For example, the LTE SL module determines [n2+T 21 ,n2+T 22 The resource selection window, T 21 and T 22 See T1 and T2 in the LTE SL resource selection mechanism, T 21 and T 22 The unit is a subframe. Where T1 ≤ 4, if the higher layer is configured with T... 2min Then T 2min ≤T2≤100, otherwise 20≤T2≤100. The above T 2min T2 is related to the priority of the data to be transmitted by the UE. Simultaneously, T2 must also meet the latency requirements of the service. For example, when PDB is less than 100 milliseconds, T2 must be less than or equal to PDB. Under the above conditions, the values of T1 and T2 depend on the UE implementation. The LTE SL module performs the following steps:
[0182] (1) Initialize all available resources in the resource selection window into a resource set A. Let any resource in resource set A be R(x,y), where x and y represent the frequency domain position and time domain position of the resource, respectively. Let M be the initial number of resources in resource set A. total .
[0183] (2) Eliminate resources based on unlistened subframes.
[0184] (3) Eliminate resources based on the detected second-side control information.
[0185] (4) If the number of remaining resources in resource set A is less than X*Mtotal, then raise the RSRP threshold by 3dB and repeat step (1). X is configured by the network, pre-configured, or predefined by the standard. For example, X is 0.2.
[0186] (5) For any remaining resource R(x,y) in resource set A, calculate the RSSI measurement value or average RSSI measurement value corresponding to resource R(x,y), and select the resource with the lowest RSSI or average RSSI in resource set A, M. total *0.2 resources are added to resource set B.
[0187] The second transmission resource includes the remaining resources in resource set A or B. As shown in Figure 13, assuming that resource set A includes resources h, u, and f after resource exclusion, then the second transmission resource includes resources h, u, and f. Alternatively, assuming that resource set B includes resources u and f after resource exclusion, then the second transmission resource includes resources u and f.
[0188] In some embodiments, the second transmission resource includes the transmission resources of the first terminal device determined after resource exclusion, which includes resource exclusion based on transmission resources indicated by the detected second side-link control information. For example, it could be the transmission resources of the determined LTE SL module. As shown in Figure 13, assuming the remaining resources in resource set B after resource exclusion include resources u and f, the LTE SL module randomly selects transmission resources from resource set B. If resource u is selected, then the second transmission resource includes resource u. Furthermore, the LTE SL module may further determine periodic transmission resources based on its own resource reservation period and the transmission resources determined in resource set B. As shown in Figure 13, assuming the LTE SL module determines resource u, then the second transmission resource includes resource u and resource v, which has the same frequency domain position as resource u and a time domain interval determined according to the resource reservation period of the LTE SL module. Here, it is assumed that the number of periods is 1.
[0189] In some embodiments, the LTE SL module sends the measured CBR simultaneously with the second transmission resource to the Uu module. For example, CBR is the proportion of sub-channels with an SL RSSI higher than a configured threshold within a measurement window [n²-d, n²-1], relative to the total number of sub-channels in the resource pool, where d equals 100 subframes. If the Uu module determines that the CBR is greater than or equal to the second threshold, it reports the second transmission resource to the network device. Otherwise, it does not report the second transmission resource. The second threshold can be configured by the network device, pre-configured, predefined by the standard, or depend on the implementation of the first terminal device.
[0190] In some embodiments, after receiving the second transmission resource reported by the Uu module, the network device schedules the third transmission resource for the first terminal device or the second terminal device.
[0191] Optionally, if the second transmission resource is the transmission resource indicated by the second side-link control information, the network device prioritizes scheduling resources that do not overlap with the second transmission resource or do not overlap in the time domain as the third transmission resource. For example, in Figure 13, if the Uu module reports resource z indicated by the second side-link control information, the network device schedules resource h, which does not overlap with resource z, as the third transmission resource, or schedules resource f, which does not overlap with z in the time domain, as the third transmission resource.
[0192] Optionally, if the second transmission resource is a periodic resource corresponding to the transmission resource indicated by the second side-link control information, the network device prioritizes scheduling resources that do not overlap with the second transmission resource or do not overlap in the time domain as the third transmission resource. For example, in Figure 13, if the Uu module reports periodic resources corresponding to the resources indicated by the second side-link control information, namely x and z, and j and i, then the network device schedules resource h, which does not overlap with the reported resources, as the third transmission resource, or schedules resource f, which does not overlap with the reported resources in the time domain, as the third transmission resource.
[0193] Optionally, if the second transmission resource is a remaining resource after resource exclusion, the resource exclusion includes resource exclusion according to the resource indicated by the second side-channel control information. The network device prioritizes scheduling the third transmission resource from the resources included in the second transmission resource reported by the first terminal device. For example, in Figure 13, assuming the Uu module reports resources h, u, and f included in resource set A after resource exclusion, the network device prioritizes scheduling h, u, or f as the third transmission resource. Alternatively, it may schedule a portion of the PRB and / or OFDM symbols included in resources h, u, and f as the third transmission resource. As another example in Figure 13, assuming the Uu module reports resources u and f included in resource set B after resource exclusion, the network device prioritizes scheduling u or f as the third transmission resource. Alternatively, it may schedule a portion of the PRB and / or OFDM symbols included in resources u and f as the third transmission resource.
[0194] Optionally, if the second transmission resource is the transmission resource of the first terminal device determined after resource exclusion, the resource exclusion includes resource exclusion according to the resource indicated by the second side-channel control information, such as the transmission resource of the determined LTE SL module. The network device prioritizes scheduling a third transmission resource that does not overlap with the second transmission resource or does not overlap in the time domain. For example, when the third transmission resource is scheduled to the first terminal device, the third transmission resource does not overlap in the time domain with the second transmission resource. For example, when the third transmission resource is scheduled to the second terminal device, the third transmission resource does not overlap with the second transmission resource or does not overlap in the time domain. For example, in Figure 13, the Uu module reports transmission resources u and v determined after LTE SL module resource exclusion. If the third transmission resource is scheduled to the first terminal device, the network device schedules resource f that does not overlap in the time domain with resources u and v. If the third transmission resource is scheduled to the second terminal device, the network device schedules resource e that does not overlap with resources u and v, or schedules resource f that does not overlap in the time domain with resources u and v.
[0195] In some embodiments, when a network device schedules a third transmission resource, the starting position of the third transmission resource in the time domain should be consistent with the position of the AGC symbol. For example, in Figure 13, assuming the first symbol of the time slot is the AGC symbol, if the scheduled third transmission resource is h or e, its starting position is the AGC symbol within the time slot, i.e., the first symbol. Referring to Figure 5, the starting position of the third transmission resource scheduled by the network should be located at the first symbol in Figure 5.
[0196] Scenario 3: In the scenario where UL dynamically shares spectrum with NR SL and LTE SL, the first terminal device reports the first transmission resource and / or the second transmission resource.
[0197] As shown in Figure 14, from the perspective of the internal structure of the first terminal device, the first terminal device includes a first side-link communication module, a second side-link communication module, and an uplink / downlink communication module. Exemplarily, the first side-link communication module is an NR SL module, the second side-link communication module is an LTE SL module, and the uplink / downlink communication module is a Uu module. Exemplarily, the Uu module is a 6G Uu module.
[0198] In some embodiments, the NR SL module listens for first sidelink control information, determines a first transmission resource based on the first sidelink control information, and passes the first transmission resource to the Uu module. The LTE SL module listens for second sidelink control information, determines a second transmission resource based on the second sidelink control information, and passes the second transmission resource to the Uu module. The Uu module reports the first transmission resource and / or the second transmission resource to the network device. Optionally, the Uu module of the first terminal device determines the time-frequency position of a third transmission resource according to the instructions of the network device and performs uplink transmission on the third transmission resource. Optionally, the network device may also schedule the third transmission resource for uplink transmission for other terminal devices (e.g., the second terminal device) based on the first transmission resource and / or the second transmission resource reported by the first terminal device.
[0199] In some embodiments, the NR SL module of the first terminal device determines the first transmission resource in time slot n1, and the LTE SL module determines the second transmission resource in subframe n2. n1 and n2 can be determined based on the time when the network device triggers the first terminal device to report transmission resources or based on the reporting period, as described in cases 1 and 2 above, respectively. Similarly, the determination of the first and second transmission resources can also refer to cases 1 and 2 above, respectively.
[0200] In some embodiments, when the NR SL module sends the first transmission resource to the Uu module, it also transmits the CBR_NR measured by the NR SL module to the Uu module. When the LTE SL module sends the second transmission resource to the Uu module, it also transmits the CBR_LTE measured by the LTE SL module to the Uu module. Optionally, if CBR_NR is greater than or equal to a first threshold, the first transmission resource is reported; otherwise, the first transmission resource is not reported. Optionally, if CBR_LTE is greater than or equal to a second threshold, the second transmission resource is reported; otherwise, the second transmission resource is not reported. Optionally, if the average, maximum, minimum, or any one of CBR_NR and CBR_LTE is greater than or equal to a third threshold, the first and second transmission resources are reported; otherwise, no transmission resources are reported. The first, second, or third threshold is configured or pre-configured by the network device, predefined by the standard, or implemented by the first terminal device.
[0201] If the Uu module reports the first transmission resource, the network device should refer to Case 1 for how to schedule the third transmission resource.
[0202] If the Uu module reports the second transmission resource, the network device should refer to case 2 for how to schedule the third transmission resource.
[0203] If the Uu module reports the first and second transmission resources, the network device should refer to the following explanation on how to schedule the third transmission resource.
[0204] In some embodiments, the first transmission resource includes at least one of the following: a transmission resource indicated by the detected first sideline control information, a periodic resource corresponding to the transmission resource indicated by the detected first sideline control information, and a PSFCH resource corresponding to the transmission resource indicated by the detected first sideline control information. The second transmission resource includes at least one of the following: a transmission resource indicated by the detected second sideline control information, and a periodic resource corresponding to the transmission resource indicated by the detected second sideline control information. Therefore, the third transmission resource scheduled by the network device should not overlap with the first transmission resource or the second transmission resource, or have temporal overlap. That is, the third transmission resource scheduled by the network device does not overlap with any resources included in the first and second transmission resources, or have temporal overlap.
[0205] In some embodiments, the first transmission resource includes remaining resources after resource exclusion, which includes resource exclusion based on transmission resources indicated by the detected first sideline control information. The second transmission resource includes remaining resources after resource exclusion, which includes resource exclusion based on transmission resources indicated by the detected second sideline control information. The network should then schedule the third transmission resource from the resources jointly comprised of the first and second transmission resources.
[0206] In some embodiments, the first transmission resource includes the transmission resources of the first terminal device determined after resource exclusion, which includes resource exclusion based on transmission resources indicated by the detected first sidelink control information. For example, the transmission resources of the determined NR SL module. The second transmission resource includes the transmission resources of the first terminal device determined after resource exclusion, which includes resource exclusion based on transmission resources indicated by the detected second sidelink control information. For example, the transmission resources of the determined LTE SL module. If the network device schedules a third transmission resource to the first terminal device, the third transmission resource scheduled by the network device should not overlap in the time domain with the first transmission resource and the second transmission resource. That is, the third transmission resource scheduled by the network device should not overlap in the time domain with any resources included in the first and second transmission resources. If the network device schedules a third transmission resource to the second terminal device, the third transmission resource scheduled by the network device should not overlap with the first transmission resource and the second transmission resource, or should overlap in the time domain. That is, the third transmission resource scheduled by the network device should not overlap with any resources included in the first and second transmission resources, or should overlap in the time domain.
[0207] In some embodiments, when a network device schedules a third transmission resource, the time-domain start position of the third transmission resource should be consistent with the position of the AGC symbol. When NR SL and LTE SL are deployed simultaneously, the position of the AGC symbol refers to the position of the AGC symbol of LTE SL. Referring to Figure 5, the time-domain start position of the third transmission resource scheduled by the network device should be located at the first symbol in Figure 5. Since the subcarrier spacing of NR SL and LTE SL may be different, i.e., one LTE subframe may correspond to multiple NR slots, and NR SL slots may also contain the AGC symbol of PSFCH, if the start position of the third transmission resource is consistent with the AGC symbol of NR SL, it will cause uplink transmission to start from the middle of the LTE subframe, resulting in fluctuations in the received power of the LTE SL receiver.
[0208] Scenario 4: The NR SL module performs resource exclusion based on the resource sensing results provided by the LTE SL module.
[0209] In some embodiments, the first terminal device reports a first transmission resource, which includes remaining resources after resource exclusion. The resource exclusion includes resource exclusion based on first sideline control information. In addition, the resource exclusion may also include resource exclusion based on second sideline control information.
[0210] In some embodiments, the first terminal device reports a first transmission resource, which includes the transmission resources of the first terminal device determined based on the remaining resources after resource exclusion. The resource exclusion includes resource exclusion based on first sideline control information. In addition, the resource exclusion may also include resource exclusion based on second sideline control information.
[0211] For example, as shown in Figure 15, from the perspective of the first terminal device's internal structure, the first terminal device includes a first side-link communication module, a second side-link communication module, and an uplink / downlink communication module. Exemplarily, the first side-link communication module is an NR SL module, the second side-link communication module is an LTE SL module, and the uplink / downlink communication module is a Uu module. Exemplarily, the Uu module is a 6G Uu module.
[0212] In some embodiments, the LTE SL module listens for second sidelink control information and instructs the NR SL module on the resource listening results, such as the listened second sidelink control information. The NR SL module listens for first sidelink control information, determines a first transmission resource based on the first sidelink control information and the resource listening results (such as including the second sidelink control information), and passes the first transmission resource to the Uu module. The Uu module reports the first transmission resource to the network device. Optionally, the Uu module of the first terminal device determines the time-frequency position of the third transmission resource according to the instructions of the network device and performs uplink transmission on the third transmission resource. Optionally, the network device may also schedule the third transmission resource for uplink transmission for other terminal devices (such as the second terminal device) based on the first transmission resource reported by the first terminal device.
[0213] In some embodiments, the NR SL module of the first terminal device determines the first transmission resource in time slot n1. For example, time slot n1 is determined based on the time when the network device triggers the first terminal device to report the first transmission resource. For instance, if the time when the Uu module receives the trigger signaling from the network device is n, then n1 = n + a, where a includes at least the time the Uu module processes the trigger signaling, the time it sends the trigger signaling to the NR SL module, and the time the NR SL module receives the trigger signaling. For example, n1 is also determined based on the period of the first terminal device reporting the first transmission resource. When the Uu module determines that time slot n is an integer multiple of the period, it sends trigger information to the NR SL module, then n1 = n + a, where a includes at least the time the Uu module sends the trigger signaling to the NR SL module and the time the NR SL module receives the trigger signaling.
[0214] The NR SL module determines a first transmission resource based on first sideline control information detected within a resource listening window. For example, the resource listening window is [n1-T]. 10 ,n1-T proc,0 ), for example, T10 For 100 or 1100 milliseconds, T proc,0 Refer to the above description. For example, T 10 The period for the first terminal device to report the first transmission resource.
[0215] The LTE SL module will indicate the resource monitoring results detected within the resource monitoring window to the NR SL module. For example, the resource monitoring results may include detected second-sideline control information. Exemplarily, the resource monitoring window is [n2-T]. 20 ,n2). For example, T 20 It is 1000 milliseconds. For example, T... 20 equal to T 10 For example, n2 can be seen in case 2 above.
[0216] In some embodiments, when the first terminal device reports a first transmission resource, the first transmission resource includes remaining resources after resource exclusion. This resource exclusion includes resource exclusion based on first sideline control information. Furthermore, the resource exclusion may also include resource exclusion based on second sideline control information. For example, the NR SL module determines [n1+T 11 ,n1+T 12 The resource selection window, T 11 and T 12 See T1 and T2 in the NR SL resource selection mechanism above. The NR SL module performs the following steps:
[0217] (1) Initialize all available resources in the resource selection window into a resource set A. Let any resource in resource set A be R(x,y), where x and y represent the frequency domain position and time domain position of the resource, respectively. Let M be the initial number of resources in resource set A. total .
[0218] (2) Eliminate resources based on unlistened time slots.
[0219] (3) Eliminate resources based on unlistened subframes.
[0220] (4) Eliminate resources based on the first side control information detected.
[0221] (5) Eliminate resources based on the detected second side control information.
[0222] (6) If the remaining resources in resource set A are less than X*M total If so, raise the RSRP threshold by 3dB and repeat step (1). X is configured or pre-configured by the network.
[0223] The first transmission resource includes the remaining resources in resource set A. As shown in Figure 11, assuming that the remaining resources after resource exclusion include resources h and u, then the first transmission resource includes resources h and u.
[0224] In some embodiments, when a first terminal device reports a first transmission resource, the first transmission resource includes the transmission resources of the first terminal device determined based on the remaining resources after resource exclusion. This resource exclusion includes resource exclusion based on first sideline control information. Furthermore, the resource exclusion may also include resource exclusion based on second sideline control information. For example, it could be the transmission resources of a determined NR SL module. As shown in Figure 11, assuming the remaining resources in resource set A after resource exclusion include resources h and u, the NR SL module randomly selects a transmission resource from resource set A. If resource u is selected, then the first transmission resource includes resource u. In addition, the NR SL module may further determine periodic transmission resources based on its own resource reservation period and the transmission resources determined in resource set A. As shown in Figure 11, assuming the NR SL module determines resource u, then the first transmission resource includes resource u and resource v, which has the same frequency domain position as resource u and a time domain interval determined based on the resource reservation period of the NR SL module. Here, it is assumed that the number of periods is 1.
[0225] In some embodiments, the NR SL module sends the measured CBR simultaneously with the first transmission resource sent to the Uu module. For example, CBR is the proportion of sub-channels with an SL RSSI higher than a configured threshold within the measurement window [n1-c, n1-1] out of the total number of sub-channels in the resource pool, where c equals 100 or 100×2. μ Each time slot has a value μ related to the subcarrier spacing. Subcarrier spacings of 15kHz, 30kHz, 60kHz, and 120kHz correspond to μ values of 0, 1, 2, and 3, respectively. If the Uu module determines that the CBR is greater than or equal to the first threshold, it reports the first transmission resource to the network device. Otherwise, it does not report the first transmission resource.
[0226] In some embodiments, when the NR SL module sends the first transmission resource to the Uu module, it also transmits the CBR_NR measured by the NR SL module to the Uu module. The LTE SL module transmits the CBR_LTE measured by the LTE SL module to the Uu module. Optionally, if CBR_NR is greater than or equal to a first threshold, the first transmission resource is reported; otherwise, the first transmission resource is not reported. Optionally, if CBR_LTE is greater than or equal to a second threshold, the first transmission resource is reported; otherwise, the first transmission resource is not reported. Optionally, if the average, maximum, minimum, or any one of CBR_NR and CBR_LTE is greater than or equal to a third threshold, the first transmission resource is reported; otherwise, the first transmission resource is not reported. The first, second, or third threshold is configured or pre-configured by the network device, predefined by the standard, or implemented by the first terminal device.
[0227] In some embodiments, after receiving the first transmission resource reported by the Uu module, the network device schedules the third transmission resource for the first terminal device or the second terminal device.
[0228] Optionally, when the first terminal device reports a first transmission resource, which includes the remaining resources after resource exclusion, the resource exclusion includes resource exclusion based on first sideline control information. Furthermore, the resource exclusion may also include resource exclusion based on second sideline control information. The network device prioritizes scheduling the third transmission resource from the resources included in the first transmission resource reported by the first terminal device. For example, as shown in Figure 11, assuming the Uu module reports resources h and u included in the resource set A after resource exclusion, the network device prioritizes scheduling h or u as the third transmission resource, or schedules a portion of the PRB and / or a portion of the OFDM symbols included in resources h and u as the third transmission resource.
[0229] Optionally, when the first terminal device reports a first transmission resource, the first transmission resource includes the transmission resources of the first terminal device determined based on the remaining resources after resource exclusion. This resource exclusion includes resource exclusion based on first sideline control information. Furthermore, this resource exclusion may also include resource exclusion based on second sideline control information, such as the transmission resources of the determined NR SL module. The network device prioritizes scheduling a third transmission resource that does not overlap with the first transmission resource or does not overlap in the time domain. For example, when the third transmission resource is scheduled to the first terminal device, the third transmission resource does not overlap in the time domain with the first transmission resource. For example, when the third transmission resource is scheduled to the second terminal device, the third transmission resource does not overlap with the first transmission resource or does not overlap in the time domain. For example, in Figure 11, the Uu module reports transmission resources u and v determined after NR SL module resource exclusion. If the third transmission resource is scheduled to the first terminal device, the network device schedules resource f, which does not overlap in the time domain with resources u and v. If the third transmission resource is scheduled to the second terminal device, the network device schedules resource e, which does not overlap in the time domain with resources u and v, or schedules resource f, which does not overlap in the time domain with resources u and v.
[0230] In some embodiments, when a network device schedules a third transmission resource, the time-domain start position of the third transmission resource should be consistent with the position of the AGC symbol. When NR SL and LTE SL are deployed simultaneously, the position of the AGC symbol refers to the position of the AGC symbol of LTE SL. Referring to Figure 5, the time-domain start position of the third transmission resource scheduled by the network device should be located at the first symbol in Figure 5. Since the subcarrier spacing of NR SL and LTE SL may be different, i.e., one LTE subframe may correspond to multiple NR slots, and NR SL slots may also contain the AGC symbol of PSFCH, if the start position of the third transmission resource is consistent with the AGC symbol of NR SL, it will cause uplink transmission to start from the middle of the LTE subframe, resulting in fluctuations in the received power of the LTE SL receiver.
