It should be noted that in the embodiments of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0070] For ease of understanding, some contents involved in the embodiments of the present application are described below:

[0071] 1. NR sidelink frequency range 2 (FR2)

[0072] In the Sidelink FR2 system, the user equipment (UE) can use the SL beam for SL transmission. The transmitting (TX) UE and the receiving (RX) UE can determine the TX beam and / or RX beam based on the beam training process before transmission, and the determined TX beam and / or RX beam are used for data transmission between UEs.

[0073] 2. NR sidelink spectrum

[0074] NR sidelink can transmit in the licensed band. If Uu (DL / UL) is transmitted in the frequency domain resources overlapping or adjacent to SL, SL transmission will interfere with Uu transmission.

[0075] 3. NR sidelink resource allocation or selection

[0076] There are two NR SL resource allocation methods, one is based on base station scheduling (mode 1), and the other is based on UE autonomous resource selection (mode 2). For the resource allocation method scheduled by the base station, the sidelink resources used by the UE for data transmission are determined by the base station and notified to the TX UE through downlink signaling; for the resource allocation method selected by the UE autonomously, the UE selects available transmission resources from the (pre) configured resource pool. Before selecting resources, the UE first performs channel monitoring, selects a resource set with less interference based on the channel monitoring (sensing) results, and then randomly selects resources for transmission from the resource set.

[0077] For mode 2, the specific working method is as follows:

[0078] 1) After the resource selection is triggered, the TX UE first determines the resource selection window. The lower boundary of the resource selection window is T1 time after the resource selection is triggered, and the upper boundary of the resource selection is T2 time after the trigger. T2 is the value selected by the UE implementation within the packet delay budget (PDB) of its TB transmission, and T2 is no earlier than T1.

[0079] 2) Before selecting resources, the UE needs to determine the candidate resource set (candidateresource set) for resource selection, and compare the reference signal received power (RSRP) measured on the resources in the resource selection window with the corresponding RSRP threshold (threshold). If the RSRP is higher than the RSRPthreshold, the resource is excluded and cannot be included in the candidate resource set. After resource exclusion, the remaining resources in the resource selection window constitute the candidate resource set. The proportion of resources in the candidate resource set to the resources in the resource selection window must be no less than x%. If it is less than x%, the RSRP threshold needs to be increased according to the step value (3dB), and then the resource exclusion operation is performed until no less than x% of resources can be selected.

[0080] 3) After the candidate resource set is determined, the UE randomly selects a transmission resource from the candidate resource set. In addition, the UE can reserve transmission resources for the next transmission during the current transmission.

[0081] The transmission method, apparatus, terminal and network side equipment provided in the embodiments of the present application are described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0082] See also Figure 2 , Figure 2is a flow chart of a transmission method provided in an embodiment of the present application, such as Figure 2 As shown, the transmission method includes the following steps:

[0083] Step 101, the terminal determines target information;

[0084] Step 102: The terminal performs secondary link SL transmission based on the target information;

[0085] The target information includes at least one of the following:

[0086] SL beams preferred by network-side devices;

[0087] SL beams that are not preferred by network-side devices;

[0088] The resources preferred by the network-side devices associated with the SL beam;

[0089] Resources not preferred by network-side devices associated with the SL beam.

[0090] In one implementation, the target information includes: an SL beam preferred by a network side device or an SL beam not preferred. The terminal determines the target information, including: the terminal receives first indication information sent by a network side device, the first indication information is used to indicate at least one of the following: an SL beam preferred by a network side device; an SL beam not preferred by a network side device.

[0091] Furthermore, the terminal determines a target SL beam based on a preferred SL beam or a non-preferred SL beam of a network-side device, and performs SL transmission based on the target SL beam.

[0092] In the related art, SL UE can transmit on the licensed band, which will interfere with the transmission of Uu (for example, UL transmission or DL ​​transmission). SL beam management mainly involves the negotiation behavior between TX UE and RX UE, and does not take into account the interference impact on the base station. This embodiment provides a SL beam control method, and the network side device (such as the base station) participates in SL beam management. When the SL UE transmits, it avoids using beam transmission that interferes with the network side device, which can be used to suppress the interference of SL transmission on the network side device.

[0093] In one embodiment, the target information includes: resources preferred or not preferred by a network side device associated with the SL beam. The terminal determines the target information, including: the terminal receives fifth indication information sent by the network side device, and the fifth indication information is used to indicate at least one of the following: resources preferred by the network side device associated with the SL beam; resources not preferred by the network side device associated with the SL beam. The resources preferred by the network side device may include frequency domain resources or time domain resources; the resources not preferred by the network side device may include frequency domain resources or time domain resources.

[0094] Furthermore, the terminal determines the SL transmission resources based on the resources preferred or not preferred by the network side device associated with the SL beam, and performs SL transmission based on the SL beam on the SL transmission resources.

[0095] It should be noted that the network side device (such as a base station) indicates the associated preferred resource (preferred resource) or non-preferred resource (non-preferred resource) for one or some SL beams (beam) of the terminal. When the terminal uses the SL beam, SL is sent on the preferred resource; or SL is sent on the preferred resource with high priority; or SL is not sent on the non-preferred resource; or SL is sent on the non-preferred resource with low priority.

[0096] It should be noted that the network-side device can indicate suitable or unsuitable transmission resources for SL transmission of different SL beams according to the scheduling or interference conditions on different resources. For example, if a certain SL beam has a large interference to the base station reception, the base station allows the UE to transmit using the SL beam in the time domain resources that are not transmitted.

[0097] In addition, the terminal can determine the SL transmission parameters based on the preferred SL beam or the non-preferred SL beam, for example, the UE adopts power control or adopts a more stringent power control parameter (i.e., the first power control parameter) when using the non-preferred SL beam, or the UE does not adopt power control or adopts a more relaxed power control parameter (i.e., the second power control parameter) when using the preferred SL beam, or the UE adopts a third power control parameter when using other SL beams.

[0098] In an embodiment of the present application, the terminal determines target information; the terminal performs sub-link SL transmission based on the target information; wherein the target information includes at least one of the following: SL beam preferred by the network side device; SL beam not preferred by the network side device; resource preferred by the network side device associated with the SL beam; resource not preferred by the network side device associated with the SL beam. In this way, the terminal can select a beam for SL transmission based on the SL beam preferred by the network side device or the SL beam not preferred, or the terminal can select a resource for SL transmission based on the resource preferred by the network side device or the resource not preferred by the network side device associated with the SL beam. In this way, the terminal can select a beam or resource that is beneficial to the UL transmission or DL ​​transmission of the terminal with reference to the preference of the network side device, thereby improving the communication effect of the terminal.

[0099] Optionally, the target information includes: at least one SL beam, the at least one SL beam including an SL beam preferred by the network side device or an SL beam not preferred;

[0100] The terminal performs SL transmission based on the target information, including:

[0101] The terminal determines a target SL beam based on the at least one SL beam, and performs SL transmission based on the target SL beam.

[0102] In one embodiment, when the at least one SL beam includes an SL beam preferred by a network side device, the terminal may select a target SL beam from the preferred SL beams. For example, the terminal may randomly select a target SL beam from the preferred SL beams, or the terminal may select a target SL beam from the preferred SL beams according to a preset beam selection rule, which is not limited in this embodiment; or, when the terminal selects a target SL beam, the preferred SL beam is selected with higher priority than other SL beams.

[0103] In one embodiment, when the at least one SL beam includes an SL beam that is not preferred by the network side device, the terminal may select a target SL beam based on the non-preferred SL beam. For example, the terminal may exclude the non-preferred SL beam when selecting the target SL beam; or, when selecting the target SL beam, the terminal may select the non-preferred SL beam with a lower priority than other SL beams.

[0104] In this embodiment, the terminal determines the target SL beam based on the at least one SL beam, and performs SL transmission based on the target SL beam, so that the terminal can refer to the network side device's preference for SL beams to select a SL beam that is beneficial to the terminal's UL transmission or DL ​​transmission, thereby supporting the terminal's SL transmission to avoid using beam transmission that interferes with the network side device, and can reduce the interference of the terminal's SL transmission on the network side device.

[0105] Optionally, the terminal determines the target information, including:

[0106] The terminal receives first indication information sent by a network side device, where the first indication information is used to indicate the at least one SL beam.

[0107] In one implementation, a network side device (such as a base station) indicates to a terminal, through a first indication message, an SL beam that is not preferred by the network side device or an SL beam that is preferred by the network side device. When the terminal performs SL transmission, the SL beam preferred by the network side device is used for SL transmission, or the SL beam preferred by the network side device is used for SL transmission with high priority; or, the SL beam not preferred by the network side device is used for SL transmission with low priority, or the SL beam not preferred by the network side device is not used for SL transmission.

[0108] In this implementation, the terminal receives first indication information sent by the network side device, and the first indication information is used to indicate the at least one SL beam, so that the network side device determines the SL beam preferred or not preferred by the network side device, and indicates the SL beam preferred or not preferred by the network side device to the terminal.

[0109] Optionally, the at least one SL beam is associated with at least one of the following:

[0110] A first receiving beam of the network side device;

[0111] Target resources;

[0112] Uplink UL beam;

[0113] Downlink DL beam.

[0114] Among them, the UL beam may include the UL transmission beam of the terminal or the UL reception beam of the network side device; the DL beam may include the DL reception beam of the terminal or the DL transmission beam of the network side device.

[0115] Among them, the network side device (such as a base station) can notify the terminal of the SL beam that the network side device does not prefer or the SL beam that the network side device prefers in the form of a UL beam or a DL beam. The UL beam or the DL beam is associated with the SL beam that the network side device does not prefer or the SL beam that the network side device prefers, for example:

[0116] The UL beam or the DL beam uses the same spatial domain filter as the first SL beam, and the first SL beam is an SL beam that is not preferred by the network side device or an SL beam that is preferred by the network side device; or

[0117] The UL beam or the DL beam covers the first SL beam, or the first SL beam covers the UL beam or the DL beam; or

[0118] The UL beam or DL ​​beam has the same beam direction, or beam width, or beam coverage, or simulated beam phase offset as the first SL beam; and so on.

[0119] Optionally, the first indication information includes at least one of the following:

[0120] Indication information of the first receiving beam of the network side device;

[0121] Indication information of the UL beam, where the UL beam is associated with a first receiving beam of the network side device;

[0122] Indication information of the DL beam, where the DL beam is associated with a first receiving beam of the network side device;

[0123] The target resource is indicated.

[0124] The SL beam not preferred by the network side device or the SL beam preferred by the network side device is associated with the first receiving beam of the network side device. The first receiving beam can be identified by the UL beam; or, if the DL beam and the UL beam are associated, the first receiving beam can be identified by the DL beam; or, the first receiving beam can be identified by an independent identifier.

[0125] In one implementation, the network side device may activate or deactivate an SL beam that is not preferred by the network side device or an SL beam that is preferred by the network side device and is associated with a first receiving beam through dedicated signaling to make it effective.

[0126] In one implementation, the network side device may implicitly activate the SL beam not preferred by the network side device or the SL beam preferred by the network side device associated with the first receiving beam through UL scheduling information or DL ​​scheduling information. The beam information in the UL scheduling information or DL ​​scheduling information implicitly reflects the first receiving beam corresponding to the effective SL beam not preferred by the network side device or the SL beam preferred by the network side device.

[0127] In one embodiment, the indication signaling of the SL beam not preferred by the network side device or the SL beam preferred by the network side device carries a first receiving beam identifier so as to distinguish that different first receiving beams correspond to different SL beams not preferred by the network side device or the SL beams preferred by the network side device.

[0128] It should be noted that, in the absence of an associated first receiving beam, the SL beam that the network-side device does not prefer or the SL beam that the network-side device prefers is effective for all receiving beams of the network-side device.

[0129] Optionally, the target resource includes at least one of the following:

[0130] Time domain resources; frequency domain resources.

[0131] In one implementation, the SL beam that the network side device does not prefer or the SL beam that the network side device prefers is associated with time domain resources, for example, a slot list, a symbol list, and the like.

[0132] Among them, the SL beam not preferred by the network side device or the SL beam preferred by the network side device is effective only in the associated time domain resources. For example, the network side device plans to schedule the uplink transmission corresponding to Rx beam #1 in certain time slots, and the SL beam not preferred by the network side device or the SL beam preferred by the network side device associated with Rx beam #1 is effective in the corresponding slot.

[0133] In addition, the indication signaling (ie, the first indication information) of the SL beam that the network side device does not prefer or the SL beam that the network side device prefers may carry time domain resource indication information, such as a time domain resource identifier.

[0134] In one implementation, the SL beam that the network-side device does not prefer or the SL beam that the network-side device prefers is associated with frequency domain resources.

[0135] Among them, the SL beam that the network side device does not prefer or the SL beam that the network side device prefers is effective only for the associated SL frequency domain resources or DL ​​frequency domain resources or UL frequency domain resources, or is effective only for the associated SL frequency domain resources and DL / UL frequency domain resource combination. For different DL / UL frequency bands, the tolerance of the network side device to interference varies, so that for certain DL / UL frequency bands, the SL beam that the network side device does not prefer or the SL beam that the network side device prefers can be designed.

[0136] The SL frequency domain resources may include at least one of the following: SL carrier; SL bandwidth part (Bandwidth Part, BWP); SL ​​pool (pool); SL ​​physical resource block (Physical Resource Block, PRB); SL ​​resource block (Resource block, RB) set (set); SL ​​sub-channel (sub-channel), etc. The DL frequency domain resources may include at least one of the following: DL carrier; DL BWP; DL RB set, etc. The UL frequency domain resources may include at least one of the following: UL carrier; UL BWP; UL RB set, etc.

[0137] In addition, the indication signaling (i.e., the first indication information) of the SL beam that the network side device does not prefer or the SL beam that the network side device prefers can carry frequency domain resource indication information, such as DL / UL carrier identifier; SL carrier identifier; frequency domain resources overlapping between SL and DL / UL; and so on.

[0138] Optionally, the SL beam group associated with the first receiving beam of the network side device includes the at least one SL beam, the SL beam group associated with the first receiving beam of the network side device is an SL beam group in at least one SL beam group, and each of the SL beam groups is associated with one or more receiving beams of the network side device.

[0139] Among them, the network side device (such as a base station) can indicate multiple sets of SL beams that the network side device does not prefer or the SL beams that the network side device prefers, each set of indication information is associated with a receiving beam of a network side device, and each set of indication information can indicate an SL beam group. When the network side device adopts the corresponding receiving beam for reception, the SL beam that the network side device does not prefer or the SL beam that the network side device prefers associated with the receiving beam takes effect.

[0140] Optionally, the at least one SL beam group includes a first beam group or a second beam group, and the SL frequency domain resources associated with the first beam group and the DL frequency domain resources are overlapping frequency domain resources, or the SL frequency domain resources associated with the first beam group and the UL frequency domain resources are overlapping frequency domain resources;

[0141] The SL frequency domain resources and DL frequency domain resources associated with the second beam group are non-overlapping frequency domain resources, or the SL frequency domain resources and UL frequency domain resources associated with the first beam group are non-overlapping frequency domain resources.

[0142] Among them, the SL beam that the network side device does not prefer or the SL beam that the network side device prefers can be associated with the frequency domain resources where SL and DL / UL overlap, or associated with the frequency domain resources where SL and DL / UL do not overlap. The SL beam that the network side device does not prefer or the SL beam that the network side device prefers is only effective on the associated resources. The network side device has different tolerance for interference depending on whether the SL and DL / UL frequency domain resources overlap, so the SL beam that the network side device does not prefer or the SL beam that the network side device prefers can be designed depending on whether the SL and DL / UL frequency domain resources overlap.

[0143] The SL frequency domain resources may include at least one of the following: SL carrier; SL BWP; SL pool; SLPRB; SL RB set; SL sub-channel, etc. The DL frequency domain resources may include at least one of the following: DL carrier; DL BWP; DL RB set, etc. The UL frequency domain resources may include at least one of the following: UL carrier; ULBWP; UL RB set, etc.

[0144] Optionally, the at least one SL beam is associated with a target resource, and the method further includes:

[0145] The terminal selects SL transmission resources based on the target resources.

[0146] In this implementation, the terminal performs SL transmission resource selection based on the target resources, thereby supporting the terminal to give high priority to the target resources associated with the preferred SL beam when selecting SL transmission resources; or to give low priority to the target resources associated with the non-preferred SL beam, so that the terminal can refer to the preference of the network side device to select the resources associated with the SL beam that are beneficial to the UL transmission or DL ​​transmission of the terminal, thereby improving the communication effect of the terminal.

[0147] Optionally, the terminal performs SL transmission resource selection based on the target resource, including:

[0148] The terminal selects a SL transmission resource based on the priority of the target resource;

[0149] Wherein, in the case where the at least one SL beam includes the preferred SL beam, the priority of the first transmission resource is higher than the transmission resources other than the first transmission resource in the SL transmission resources, and the first transmission resource is the transmission resource in the target resource associated with the preferred SL beam; or

[0150] In the case that the at least one SL beam includes the non-preferred SL beam, the priority of the second transmission resource is lower than the transmission resources other than the second transmission resource in the SL transmission resources, and the second transmission resource is the transmission resource in the target resource associated with the non-preferred SL beam.

[0151] It should be noted that there is a correlation between the SL beam not preferred by the network side device or the SL beam preferred by the network side device and the time domain and / or frequency domain resources, and the terminal can select SL transmission resources based on the correlation. For example, when the terminal selects SL transmission resources, it selects the time domain and / or frequency domain resources corresponding to the SL beam preferred by the network side device with high priority; or selects the time domain and / or frequency domain resources corresponding to the SL beam preferred by the network side device. For example, when the terminal selects SL resources, it selects the time domain and / or frequency domain resources corresponding to the SL beam not preferred by the network side device with low priority; or excludes the time domain and / or frequency domain resources corresponding to the SL beam not preferred by the network side device.

[0152] Optionally, the terminal performs SL transmission resource selection based on the target resource, including:

[0153] The terminal determines a resource selection window, and determines a candidate resource set based on the resource selection window;

[0154] The terminal performs SL transmission resource selection based on the candidate resource set;

[0155] The resources in the resource selection window are determined based on the target resource, or the candidate resource set is determined based on the target resource.

[0156] In this embodiment, the resources within the resource selection window are determined based on the target resources, so that when determining the resources within the resource selection window, the target resources associated with the preferred SL beam can be given high priority, or the target resources associated with the non-preferred SL beam can be given low priority; or, the alternative resource set is determined based on the target resources, so that when determining the alternative resource set, the target resources associated with the preferred SL beam can be given high priority, or the target resources associated with the non-preferred SL beam can be given low priority.

[0157] Optionally, in a case where the at least one SL beam includes the preferred SL beam:

[0158] The resources in the resource selection window are resources in the first transmission resource; or,

[0159] The resources within the resource selection window include all first transmission resources; or,

[0160] The candidate resource set includes at least part of the first transmission resources; or,

[0161] The resources in the candidate resource set are resources in the first transmission resource; or,

[0162] In the process of determining the candidate resource set, the energy measurement value corresponding to the first transmission resource in the resource selection window is increased by a first preset value; or,

[0163] In the process of determining the candidate resource set, the energy threshold corresponding to the first transmission resource in the resource selection window is reduced by a second preset value; or

[0164] In the process of selecting the SL transmission resource, the selection priority of the first transmission resource in the candidate resource set is higher than the transmission resources other than the first transmission resource; or

[0165] In the process of selecting the SL bearer or the SL resource pool, the SL bearer or the SL resource pool on the first transmission resource has a higher selection priority than the SL bearer or the SL resource pool on the transmission resource other than the first transmission resource;

[0166] Among them, the first transmission resource is a transmission resource in the target resource associated with the preferred SL beam.

[0167] Among them, the energy measurement value may include: RSRP; Received Signal Strength Indication (RSSI); Reference Signal Received Quality (RSRQ); Signal to Interference Ratio (SIR); Signal-to-noise and interference ratio (SINR), etc. The first preset value can be set in advance, and the present embodiment does not limit the specific value of the first preset value. The energy threshold may include: RSRP threshold; RSSI threshold; RSRQ threshold; SIR threshold; SINR threshold, etc. The energy threshold may be a threshold of the energy measurement value. The second preset value can be set in advance, and the present embodiment does not limit the specific value of the second preset value.

[0168] In one implementation, for the SL beam preferred by the network side device, the UE (ie, the terminal) has the following options for SL transmission resource selection:

[0169] Option 1: The TX UE determines that the resource selection window is only within the time domain resources associated with the SL beam preferred by the network side device, or the resource selection window determined by the TX UE includes the time domain resources associated with the SL beam preferred by the network side device.

[0170] Option 2: When the TX UE determines the set of candidate resources, it ensures that at least the candidate resources exist within the time domain resources associated with the SL beam preferred by the network-side device.

[0171] Option 3: When the TX UE determines the candidate resource set, it excludes resources other than the time domain resources / frequency domain resources / time-frequency resources associated with the SL beam preferred by the network-side device.

[0172] Option 4: When the TX UE determines the alternative resource set, the energy measurement value associated with the resources in the time domain resources / frequency domain resources / time-frequency resources associated with the SL beam preferred by the network side device is increased by M energy units.

[0173] Option 5: When the TX UE determines the alternative resource set, the energy threshold associated with the resources in the time domain resources / frequency domain resources / time-frequency resources associated with the SL beam preferred by the network side device is reduced by N energy units. The energy unit can be watts or dB, etc. N is a preset value. The energy threshold can include at least one of the following: RSRP threshold; RSSI threshold; RSRQ threshold; SIR threshold; SINR threshold.

[0174] Option 6: When the medium access control (MAC) layer of the TX UE selects transmission resources from a set of candidate resources, it gives priority to candidate resources located in the time domain resources / frequency domain resources / time-frequency resources associated with the SL beam preferred by the network-side device.

[0175] Option 7: When the MAC layer of the TX UE selects an SL carrier / SL resource pool, it gives priority to selecting an SL carrier or SL resource pool located on the frequency domain resources associated with the SL beam preferred by the network-side device.

[0176] It should be noted that the above-mentioned rules of Option 1 to Option 7 are effective when the UE adopts the SL beam preferred by the network-side device for SL transmission.

[0177] Optionally, in a case where the at least one SL beam includes the unpreferred SL beam:

[0178] The candidate resource set does not include the second transmission resource; or,

[0179] In the process of determining the candidate resource set, the energy measurement value corresponding to the second transmission resource in the resource selection window is reduced by a third preset value; or,

[0180] In the process of determining the candidate resource set, the energy threshold corresponding to the second transmission resource in the resource selection window is increased by a fourth preset value; or

[0181] In the process of selecting the SL transmission resource, the selection priority of the second transmission resource in the candidate resource set is lower than that of transmission resources other than the second transmission resource; or

[0182] In the process of selecting the SL bearer or the SL resource pool, the selection priority of the SL bearer or the SL resource pool on the second transmission resource is lower than the SL bearer or the SL resource pool on the transmission resource other than the second transmission resource;

[0183] The second transmission resource is a transmission resource in the target resource that is associated with the non-preferred SL beam.

[0184] Among them, the energy measurement value may include: RSRP; RSSI; RSRQ; SIR; SINR, etc. The third preset value may be pre-set, and the present embodiment does not limit the specific value of the third preset value. The energy threshold may include: RSRP threshold; RSSI threshold; RSRQ threshold; SIR threshold; SINR threshold, etc. The energy threshold may be a threshold of the energy measurement value. The fourth preset value may be pre-set, and the present embodiment does not limit the specific value of the fourth preset value.

[0185] For SL beams that are not preferred by the network side device, the UE (i.e., terminal) has the following options for SL transmission resource selection:

[0186] Option 1: When the TX UE determines the candidate resource set, it excludes the resources in the time domain resources / frequency domain resources / time-frequency resources associated with the SL beam that is not preferred by the network-side device.

[0187] Option 2: When the TX UE determines the alternative resource set, the energy measurement value associated with the resources in the time domain resources / frequency domain resources / time-frequency resources associated with the SL beam not preferred by the network side device is reduced by M energy units. The energy unit can be watts or dB, etc. M is a preset value. The energy measurement value can include at least one of the following: RSRP; RSSI; RSRQ; SIR; SINR.

[0188] Option 3: When the TX UE determines the alternative resource set, the energy threshold associated with the resources in the time domain resources / frequency domain resources / time-frequency resources associated with the SL beam not preferred by the network-side device is increased by N energy units. The energy unit can be watts or dB, etc. N is a preset value. The energy threshold can include at least one of the following: RSRP threshold; RSSI threshold; RSRQ threshold; SIR threshold; SINR threshold.

[0189] Option 4: When the MAC layer of the TX UE selects transmission resources from the candidate resource set, it gives low priority to or excludes the candidate resources in the time domain resources / frequency domain resources / time-frequency resources associated with the SL beam that is not preferred by the network-side device.

[0190] Option 5: When the MAC layer of the TX UE selects an SL carrier or an SL resource pool, it gives low priority to or excludes the SL carrier or the SL resource pool on the frequency domain resources associated with the SL beam that the network-side device does not prefer.

[0191] It should be noted that the above-mentioned rules of Option 1 to Option 5 are effective when the UE uses an SL beam that is not preferred by the network-side device for SL transmission.

[0192] Optionally, the at least one SL beam is determined based on a signal measurement result, and the signal measurement result is a measurement result obtained by measuring a measurement signal.

[0283] It should be noted that this embodiment is Figure 2 The implementation of the corresponding network side device in the embodiment shown in the figure can be found in the specific implementation of Figure 2 To avoid repeated description of the embodiment shown, the present embodiment will not be described in detail.

[0284] The transmission method provided by the embodiment of the present application is described below through several specific embodiments:

[0285] In the following embodiments, a base station is used as an example for description.

[0286] Embodiment 1:

[0287] like Figure 4As shown, the base station indicates "non-preferred SL beam(s)" or "preferred SL beam(s)" to the UE. When the UE performs SL transmission, it (preferentially) uses "preferred SL beam(s)", or uses "non-preferred SL beam(s)" with low priority or does not use it.

[0288] In one implementation manner, the “non-preferred SL beam(s)” or the “preferred SL beam(s)” is associated with an Rx beam of the base station.

[0289] Optionally, the base station may indicate multiple sets of "non-preferred SL beam(s)" or "preferred SL beam(s)", and each set of indication information is associated with an Rx beam of the base station. When the base station uses the corresponding Rx beam for reception, the "non-preferred SL beam(s)" or "preferred SL beam(s)" associated with the Rx beam takes effect.

[0290] Optionally, the Rx beam may be identified by a UL beam; or, if a DL beam and a UL beam are associated, the Rx beam may be identified by a DL beam; or, the Rx beam may be identified by an independent identifier.

[0291] Optionally, the base station may activate or deactivate a "non-preferred SL beam(s)" or "preferred SL beam(s)" associated with a certain Rx beam through dedicated signaling to make it effective.

[0292] Optionally, the base station may implicitly activate a "non-preferred SL beam(s)" or "preferred SL beam(s)" associated with a certain Rx beam through UL scheduling information or DL ​​scheduling information. The beam information in the UL scheduling information or DL ​​scheduling information implicitly reflects the Rx beam corresponding to the effective "non-preferred SL beam(s)" or "preferred SL beam(s)".

[0293] Optionally, the indication signaling of "non-preferred SL beam(s)" or "preferred SL beam(s)" carries an Rx beam identifier to distinguish different Rx beams corresponding to different "non-preferred SL beam(s)" or "preferred SL beam(s)".

[0294] Optionally, in the case of no associated Rx beam, the "non-preferred SL beam(s)" or "preferred SL beam(s)" is effective for all Rx beams of the base station.

[0295] Optionally, the “non-preferred SL beam(s)” or “preferred SL beam(s)” is associated with time domain resources, for example, a slot list, a symbol list, or the like.

[0296] Optionally, the "non-preferred SL beam(s)" or "preferred SL beam(s)" is effective only in the associated time domain resources. For example, the base station plans to schedule the uplink transmission corresponding to Rx beam#1 in certain slots, and the "non-preferred SL beam(s)" or "preferred SL beam(s)" associated with Rxbeam#1 is effective in the corresponding slot.

[0297] Optionally, the indication signaling of "non-preferred SL beam(s)" or "preferred SL beam(s)" carries the time domain resource indication information, such as a time domain resource identifier.

[0298] In one implementation manner, the “non-preferred SL beam(s)” or the “preferred SL beam(s)” is associated with frequency domain resources.

[0299] Optionally, the "non-preferred SL beam(s)" or "preferred SL beam(s)" is effective only for the associated SL frequency domain resources or DL ​​frequency domain resources or UL frequency domain resources, or is effective only for the associated SL frequency domain resources and DL / UL frequency domain resources. For different DL / UL frequency bands, the tolerance of the base station to interference varies, so "non-preferred SL beam(s)" or "preferred SL beam(s)" can be designed for certain DL / UL frequency bands.

[0300] The SL frequency domain resources may include at least one of the following: SL carrier; SL BWP; SL pool; SLPRB; SL RB set; SL sub-channel, etc. The DL frequency domain resources may include at least one of the following: DL carrier; DL BWP; DL RB set, etc. The UL frequency domain resources may include at least one of the following: UL carrier; ULBWP; UL RB set, etc.

[0301] Optionally, the "non-preferred SL beam(s)" or "preferred SL beam(s)" can be associated with frequency domain resources where SL and DL / UL overlap, or associated with frequency domain resources where SL and DL / UL do not overlap. The "non-preferred SL beam(s)" or "preferred SL beam(s)" is only effective on the associated resources. Depending on whether the SL and DL / UL frequency domain resources overlap, the base station has different tolerance for interference, so "non-preferred SL beam(s)" or "preferred SL beam(s)" can be designed based on whether the SL and DL / UL frequency domain resources overlap.

[0302] The SL frequency domain resources may include at least one of the following: SL carrier; SL BWP; SL pool; SL PRB; SL RB set; SL sub-channel, etc. The DL frequency domain resources may include at least one of the following: DL carrier; DLBWP; DL RB set, etc. The UL frequency domain resources may include at least one of the following: UL carrier; UL BWP; UL RBset, etc.

[0303] Optionally, the indication signaling of "non-preferred SL beam(s)" or "preferred SL beam(s)" carries frequency domain resource indication information, such as DL / UL carrier identifier; SL carrier identifier; frequency domain resources overlapping between SL and DL / UL, etc.

[0304] In one implementation, if the effective "non-preferred SL beam(s)" or "preferred SL beam(s)" is associated with time domain and / or frequency domain resources, the UE may select SL transmission resources according to the association.

[0305] Optionally, when the UE selects SL transmission resources, it gives priority to the time domain and / or frequency domain resources corresponding to the "preferred SL beam(s)"; or selects the time domain and / or frequency domain resources corresponding to the "preferred SL beam(s)".

[0306] For "preferred SL beam(s)", the UE has the following options for SL transmission resource selection:

[0307] Option 1: The TX UE determines that the resource selection window is only within the time domain resources associated with the "preferred SL beam(s)", or the resource selection window determined by the TX UE includes the time domain resources associated with the "preferred SL beam(s)".

[0308] Option 2: When the TX UE determines the candidate resource set, it ensures that at least there are candidate resources in the time domain resources associated with the "preferred SL beam(s)".

[0309] Option 3: When the TX UE determines the candidate resource set, it excludes resources other than the time domain resources / frequency domain resources / time-frequency resources associated with the "preferred SL beam(s)".

[0310] Option 4: When the TX UE determines the alternative resource set, the energy measurement value associated with the resources in the time domain resources / frequency domain resources / time-frequency resources associated with the "preferred SL beam(s)" is increased by M energy units, where the energy unit may be watts or dB, etc. M is a preset value, and the energy measurement value may include at least one of the following: RSRP; RSSI; RSRQ; SIR; SINR.

[0311] Option 5: When the TX UE determines the candidate resource set, the energy threshold associated with the resources in the time domain resources / frequency domain resources / time-frequency resources associated with the "preferred SL beam(s)" is reduced by N energy units, where the energy unit may be watts or dB, etc. N is a preset value, and the energy threshold may include at least one of the following: RSRP threshold; RSSI threshold; RSRQ threshold; SIR threshold; SINR threshold.
