As long as the same technical effect is achieved, the base station is not limited to specific technical terms. 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.

[0050] To facilitate understanding, the application scenarios of the embodiments of the present application, as well as the related technologies and concepts involved, are first introduced.

[0051] 1. Application scenarios

[0052] The technical solution provided in the embodiment of the present application can be applied to sidelink transmission, sidelink positioning and other scenarios. Figure 2 As shown, terminal 1 can perform side link transmission with terminal 2, terminal 3, and terminal 4 through a side link, such as sending / receiving / measuring a side link channel or signal. At the same time, terminal 1 can communicate with the network side device through an uplink (Uplink) and a downlink (Downlink).

[0053] As described above, the LTE system supports sidelink transmission, that is, data is transmitted directly between terminals at the physical layer without going through network-side devices. The LTE system sidelink is based on broadcast communication. Although it can be used to support basic safety communications in the Internet of Vehicles, it is not suitable for other more advanced V2X services. The 5G new air interface system supports more advanced sidelink transmission designs, such as unicast, multicast or groupcast, so as to support a more comprehensive range of service types.

[0054] II. Allocation / selection of new air interface sidelink resources

[0055] There are two new air interface side link resource allocation modes, one is a resource allocation mode based on base station scheduling, namely mode 1, and the other is a resource allocation mode based on terminal autonomous selection, namely mode 2.

[0056] For mode 1, the sidelink resources used by the terminal for data transmission are determined by the base station, and the base station notifies the sending terminal (TX UE) through downlink signaling; for mode 2, the terminal selects available transmission resources from the (pre-)configured resource pool. Before selecting resources, the terminal first performs channel sensing, selects a resource set with less interference based on the channel sensing results, and then randomly selects resources for transmission from the selected resource set.

[0057] For mode 2, the specific working method is as follows:

[0058] 1) After the resource selection is triggered, the sending terminal 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 window is T2 time after the resource selection is triggered. T2 is the value selected by the terminal implementation within the packet delay budget (PDB) transmitted in its transport block (TB), and T2 is no earlier than T1;

[0059] 2) Before selecting resources, the terminal needs to determine the candidate resource set (candidate resourceset) 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 of a resource is higher than the RSRP threshold, the resource will be excluded and cannot be included in the candidate resource set. The remaining resources in the resource selection window after the resource exclusion process constitute the candidate resource set. The ratio of resources in the candidate resource set to 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, such as 3dB, and then the above-mentioned resource exclusion process operation is performed until no less than x% of resources can be selected;

[0060] 3) After the candidate resource set is determined, the terminal randomly selects a transmission resource from the candidate resource set.

[0061] In addition, the terminal may reserve transmission resources for subsequent transmissions during this transmission.

[0062] 3. About Beam

[0063] Due to the scarcity of low-frequency resources, 5G new air interface uses high-frequency bands such as millimeter waves. Since the propagation loss of high-frequency bands is greater than that of low-frequency bands, its coverage distance is worse than that of LTE. One solution is that 5G new air interface uses multi-antenna beamforming (Beam Forming) to achieve signal enhancement and thus enhance coverage. Beamforming technology is a signal processing technology that uses a sensor array to send and receive signals in a direction. Beamforming technology adjusts the parameters of the basic unit of the phase array so that signals at certain angles obtain constructive interference, while signals at other angles obtain destructive interference, so that the antenna beam points to a specific direction. The establishment of the downlink beam is generally determined by the synchronization signal block (Synchronization Signal Block, SSB) and the channel state information reference signal (Channel State Information-Reference Signal, CSI-RS).

[0064] Take SSB as an example: Since the beam is narrow, the same SSB is sent to different directions in the form of beams in the new air interface according to the time division duplexing (TDD) method, so that terminals in all directions can receive the SSB. Figure 3As shown, within the range of 5ms, the base station sends multiple SSBs corresponding to different SSB indexes (Index), covering different directions respectively. UE1 and UE2 receive multiple SSBs with different signal strengths and select the strongest one as their own SSB beam.

[0065] IV. About Transmission Configuration Indication (TCI)

[0066] At the Uu port, TCI can be indicated by downlink control information (DCI), and TCI will be associated with a reference signal. The physical downlink shared channel (PDSCH) / physical uplink shared channel (PUSCH) scheduled by DCI and the reference signal corresponding to TCI are quasi-colocation (QCL). In other words, the beam of the reference signal is the same as the beam of the PDSCH, so through TCI, the terminal can know which beam to use to receive data. The TCI used to control the beam of PDSCH is called the downlink TCI (DL TCI), and the TCI used to control the beam of PUSCH is called the uplink TCI (UL TCI), and PUSCH / PDSCH is also allowed to share the same set of TCI, which can be simply called TCI.

[0067] The base station can enable the terminal to switch to different beams by modifying TCI, but this process may involve DCI decoding and beam switching. Therefore, the switching beam will not take effect immediately after sending / receiving TCI. Instead, it requires a certain processing time, and the terminal cannot send / receive during the processing time.

[0068] 5. About Hidden Node and Exposed Node

[0069] like Figure 4 As shown, there is an obstruction between the two transmitting terminals, and the two transmitting terminals cannot monitor the reservation signaling sent by the other party on the FR2 frequency band, resulting in a hidden node problem, thereby interfering with the reception of the receiving terminal.

[0070] like Figure 5 As shown, two transmitting terminals use directional beams for side link transmission. Since the transmitting beams of the transmitting terminals point in different directions, they cannot monitor each other's reserved signaling, resulting in a hidden node problem, thereby interfering with the reception of the receiving terminal.

[0071] like Figure 6 As shown in the figure, UE1 wants to transmit data to UE2, but UE1 detects the resource reservation information between UE3 and UE4 and thinks that it will interfere with UE2's reception, so it excludes the reserved resources of UE3 and UE4. However, because there is a directional beam between UE3 and UE4, the transmission of UE3 and UE4 will not affect UE2's reception. In this case, the excluded resources should not be excluded.

[0072] 6. About terminal capabilities

[0073] In the relevant 3GPP meeting, it was mentioned that priority is given to the terminal not being able to use multiple beams to send or receive at the same time. It is believed that the terminal can only use one beam to perform detection or transmission at the same time, and cannot use multiple beams to perform detection or transmission at the same time.

[0074] The application scenarios, related technologies and concepts of the embodiments of the present application are introduced above. The sidelink resource selection method provided by the embodiments of the present application is described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0075] See also Figure 7 As shown, it is an implementation flow chart of a side link resource selection method provided in an embodiment of the present application, and the method includes the following steps:

[0076] S710: The terminal determines a target object according to the first measurement result or the second measurement result, where the target object includes a transmission resource or a transmission beam or coordination information;

[0077] The first measurement result includes at least one of the following:

[0078] Channel state information results;

[0079] Affirm the results;

[0080] Transmission success result;

[0081] The second measurement result includes at least one of the following:

[0082] Negative confirmation results;

[0083] Transmission failure results;

[0084] Send results non-continuously.

[0085] By applying the method provided in the embodiment of the present application, the terminal determines the target object according to the first measurement result or the second measurement result, where the target object includes transmission resources or transmission beams or collaboration information. It clarifies how the terminal determines the beams or resources under the side link FR2, and accurately determines the target object, which helps to improve the side link transmission efficiency and side link transmission reliability.

[0086] In the embodiment of the present application, the terminal may be Figure 1 The terminal 11 shown, or Figure 2 The terminal 1 or terminal 2 or terminal 3 or terminal 4 shown, the terminal detects or receives based on the beam, and can obtain a first measurement result or a second measurement result. The first measurement result is such as a channel state information (CSI) result, a positive confirmation (ACK) result, a transmission success result, and the second measurement result is such as a negative confirmation (NACK) result, a transmission failure result, a discontinuous transmission (DTX) result, etc. It should be noted that the terminal detects or receives based on the beam, which is actually based on a reference signal or resource configured with TCI. In other words, it can be understood as sending, detecting, or receiving based on a certain TCI configuration. The resources associated with the beam can also be considered as resources associated with a reference signal / TCI / QCL type / terminal identifier.

[0087] The positive confirmation result may include the number of positive confirmations or the positive confirmation ratio, and the positive confirmation refers to the successful reception information of the hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ)-acknowledgement (Acknowledgement, ACK) information fed back by the receiving end, including the case where there is no feedback under the NACK only mechanism;

[0088] Or, the negative confirmation result includes the number of negative confirmations or the negative confirmation ratio, where the negative confirmation refers to negative information of hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ)-acknowledgement (Acknowledgement, ACK) information fed back by the receiving end, including the situation where no feedback from the receiving end is received;

[0089] Or, the transmission success result includes the number of successful transmissions or the ratio of successful transmissions, and the successful transmission means that the receiving end successfully receives a physical sidelink control channel (Physical Sidelink Control Channel, PSCCH) or a physical sidelink shared channel (Physical Sidelink Share Channel, PSSCH);

[0090] or, the transmission failure result includes the number of transmission failures or the transmission failure ratio;

[0091] Or, the discontinuous transmission result includes the number of discontinuous transmissions or the discontinuous transmission ratio. For example, discontinuous transmission means that the receiving end does not receive the PSCCH or PSSCH, but the transmitting end actually sends it.

[0092] It can be understood that the higher the value corresponding to the first measurement result, or the lower the value corresponding to the second measurement result, the better the beam quality, and the better the beam quality, the more successful transmission times. Conversely, the lower the value corresponding to the first measurement result, or the higher the value corresponding to the second measurement result, the worse the beam quality, and the worse the beam quality, the more failed transmission times.

[0093] In some embodiments, the terminal determines the target object based on the first measurement result or the second measurement result. The terminal determines the target object based on one or more first measurement results, or the terminal determines the target object based on one or more second measurement results, or the terminal determines the target object based on one or more first measurement results and one or more second measurement results. The terminal can determine the target object based on the first measurement result or the second measurement result. The target object includes transmission resources or transmission beams or collaborative information. The transmission resources may include transmission resources or reception resources, the transmission beam may include transmission beams or reception beams, and the collaborative information may include recommended resources (preferred resources) or recommended beams or non-preferred resources (non-preferred resources) or non-recommended beams.

[0094] In some embodiments of the present application, the terminal determines the target object according to the first measurement result or the second measurement result, which may include the following steps:

[0095] Step 1: The terminal determines a reference signal received power threshold or an increase value of the reference signal received power threshold corresponding to the candidate resource according to the first measurement result or the second measurement result;

[0096] Step 2: The terminal determines a candidate resource set of the sidelink based on the reference signal received power threshold or the raised value of the reference signal received power threshold;

[0097] Step 3: The terminal determines the target object based on the candidate resource set.

[0098] For the convenience of description, the above three steps are combined for explanation.

[0099] In an embodiment of the present application, different first measurement results or second measurement results may correspond to different reference signal received power thresholds (RSRP thresholds), or different first measurement results or second measurement results may correspond to different reference signal received power threshold boost values ​​(RSRP threshold boost up value). The terminal may determine the reference signal received power threshold or the boost value of the reference signal received power threshold corresponding to the candidate resource based on the first measurement result or the second measurement result. The candidate resource here may be a candidate resource associated with a beam, or a candidate resource associated with a reference signal (Channel State Information-Reference Signal (CSI-RS) / Demodulation Reference Signal (DMRS) / S-SSB), TCI, QCL type or terminal identifier, and the reference signal, TCI, QCL type or terminal identifier is associated with a first measurement result or a second measurement result. For example, if the terminal measures a first measurement result or a second measurement result based on a reference signal configured with a TCI, the terminal determines the reference signal received power threshold or the boost value of the reference signal received power threshold corresponding to the candidate resource associated with the reference signal configured with the TCI based on the measurement result. Alternatively, the terminal measures a first measurement result or a second measurement result based on a beam direction, and then determines a reference signal received power threshold or an increase value of the reference signal received power threshold corresponding to a candidate resource associated with the beam direction according to the measurement result.

[0100] The terminal can determine the candidate resource set of the sidelink based on the reference signal received power threshold. For example, if the reference signal received power corresponding to the candidate resource is greater than or equal to the corresponding reference signal received power threshold, the candidate resource may not be included in the candidate resource set, or the candidate resource may be excluded from the candidate resource set. If the reference signal received power of the candidate resource is less than the corresponding reference signal received power threshold, the candidate resource may be added to the candidate resource set, or the candidate resource may not be excluded from the candidate resource set. It can be understood that the reference signal received power threshold generally refers to the initial reference signal received power threshold used by the terminal in the resource exclusion process.

[0101] Alternatively, the terminal may determine the candidate resource set of the sidelink based on the raised value of the reference signal received power threshold. For example, when the number or proportion of candidate resources in the candidate resource set does not meet the requirements, the terminal needs to raise the reference signal received power threshold so that the number or proportion of candidate resources in the candidate resource set meets the requirements. The terminal determines the raised value of the reference signal received power threshold based on the first measurement result or the second measurement result, and raises the current reference signal received power threshold corresponding to the candidate resource based on the raised value, thereby obtaining a new reference signal received power threshold. At this time, if the reference signal received power corresponding to the candidate resource is greater than or equal to the corresponding new reference signal received power threshold, the candidate resource may not be included in the candidate resource set, or the candidate resource may be excluded from the candidate resource set. If the reference signal received power of the candidate resource is less than the corresponding new reference signal received power threshold, the candidate resource may be added to the candidate resource set, or the candidate resource may not be excluded from the candidate resource set.

[0102] After the terminal determines the candidate resource set, it can determine the target object based on the candidate resource set. The candidate resource set is determined based on the reference signal received power threshold or the raised value of the reference signal received power threshold, which is related to the beam quality and helps to more accurately determine the target object.

[0103] Optionally, when the first measurement result is greater than or equal to the first threshold, or the second measurement result is less than or equal to the second threshold, the terminal can determine the value after the initial threshold of the reference signal received power is increased by the first value or the positive infinity value as the reference signal received power threshold corresponding to the candidate resource.

[0104] The initial threshold of the reference signal receiving power may be predefined by the protocol, or preconfigured by the network side device, or configured by the network side device, or determined by the terminal, or a threshold configured when working in the FR1 frequency band, or a threshold configured when the beam quality is not considered.

[0105] The first threshold or the second threshold may be predefined by the protocol, or preconfigured by the network side device, or configured by the network side device, or determined by the terminal. The first value may be predefined by the protocol, or preconfigured by the network side device, or configured by the network side device, or determined by the terminal.

[0106] Optionally, there are multiple first thresholds or second thresholds, and the first value is respectively different, different first thresholds or second thresholds correspond to different first values, the larger the first threshold is, the larger the corresponding first value is, or the smaller the second threshold is, the larger the corresponding first value is. For example, the first threshold A corresponds to the first value A, the first threshold B corresponds to the first value B, the first threshold A is greater than the first threshold B, and the first value A is greater than the first value B. If the first measurement result is greater than or equal to the first threshold B and less than the first threshold A, the initial threshold of the reference signal received power can be increased by the first value B as the reference signal received power threshold corresponding to the candidate resource, and if the first measurement result is greater than or equal to the first threshold A, the initial threshold of the reference signal received power can be increased by the first value A as the reference signal received power threshold corresponding to the candidate resource.

[0107] Optionally, the first value is a value in a first value set, and the first value set may be predefined by a protocol, or preconfigured by a network side device, or configured by a network side device, or determined by a terminal. The first value may be selected from the first value set according to the first measurement result or the second measurement result.

[0108] When the first measurement result is greater than or equal to the first threshold, or the second measurement result is less than or equal to the second threshold, the terminal determines the value after the initial threshold of the reference signal received power is increased by the first value or the positive infinite value as the reference signal received power threshold corresponding to the candidate resource, so that the better the beam quality, the larger the reference signal received power threshold. Because the higher the value corresponding to the first measurement result, or the lower the value corresponding to the second measurement result, the stronger the anti-interference ability, the greater the possibility of successful transmission. If the reference signal received power threshold corresponding to the candidate resource is larger, it is less likely to be excluded when the resource is excluded, and it is easier to select these resources for transmission. If different candidate resources are associated with different transmission beams, it is easier to select a transmission beam with good beam quality.

[0109] Optionally, when the first measurement result is less than or equal to the third threshold, or the second measurement result is greater than or equal to the fourth threshold, the terminal can determine the value after the initial reference signal reception power threshold is reduced by the second value or the initial reference signal reception power threshold as the reference signal reception power threshold corresponding to the candidate resource.

[0110] The third threshold or the fourth threshold may be predefined by the protocol, or preconfigured by the network side device, or configured by the network side device, or determined by the terminal. The second value may be predefined by the protocol, or preconfigured by the network side device, or configured by the network side device, or determined by the terminal.

[0111] Optionally, there are multiple third thresholds or fourth thresholds, and the second value, respectively, and different third thresholds or fourth thresholds correspond to different second values. The smaller the third threshold, the larger the corresponding second value, or the larger the fourth threshold, the larger the corresponding second value. For example, the third threshold A corresponds to the second value A, the third threshold B corresponds to the second value B, the third threshold A is less than the third threshold B, and the second value A is greater than the second value B. If the first measurement result is less than or equal to the third threshold B and greater than the third threshold A, the initial threshold of the reference signal received power can be reduced by the second value B as the reference signal received power threshold corresponding to the candidate resource. If the first measurement result is less than or equal to the third threshold A, the initial threshold of the reference signal received power can be reduced by the second value A as the reference signal received power threshold corresponding to the candidate resource.

[0112] Optionally, the second value is a value in a second value set, and the second value set may be predefined by a protocol, or preconfigured by a network side device, or configured by a network side device, or determined by a terminal. The second value may be selected from the second value set according to the first measurement result or the second measurement result.

[0113] When the first measurement result is less than or equal to the third threshold, or the second measurement result is greater than or equal to the fourth threshold, the terminal determines the reference signal received power threshold corresponding to the candidate resource as the reference signal received power threshold corresponding to the candidate resource, so that the lower the value corresponding to the first measurement result, or the higher the value corresponding to the second measurement result, the smaller the reference signal received power threshold. Because the lower the value corresponding to the first measurement result, or the higher the value corresponding to the second measurement result, the weaker the anti-interference ability, the smaller the possibility of successful transmission. If the reference signal received power threshold corresponding to the candidate resource is smaller, it is easier to be excluded when the resource is excluded, and it is more difficult to select these resources for transmission. If different candidate resources are associated with different transmission beams, it is easier to select a transmission beam with good beam quality.

[0114] Optionally, the terminal may determine, according to the first measurement result or the second measurement result, a reference signal received power threshold corresponding to the candidate resource when the first measurement result or the second measurement result satisfies the first condition;

[0115] The first condition may include at least one of the following:

[0116] greater than or equal to a fifth threshold;

[0117] is less than or equal to a sixth threshold;

[0118] The number or proportion of the first measurement results greater than or equal to the seventh threshold is greater than or equal to an eighth threshold;

[0119] The number or proportion of the second measurement results that are less than or equal to the ninth threshold is greater than or equal to the tenth threshold.

[0120] That is, when the first measurement result or the second measurement result satisfies the above-mentioned first condition, the reference signal received power threshold corresponding to the candidate resource is determined according to the first measurement result or the second measurement result. For example, a resource exclusion scheme based on the first measurement result or the second measurement result corresponding to different reference signal received power thresholds is applied, or a resource exclusion scheme based on the reference signal received power threshold is applied, or a scheme in which different first thresholds or second thresholds correspond to different reference signal received power thresholds is applied. It can be understood that if the value corresponding to the first measurement result is too low or the value corresponding to the second measurement result is too high, the corresponding reference signal received power threshold is too low and has no use value. Conversely, if the value corresponding to the first measurement result is too high or the value corresponding to the second measurement result is too low, the corresponding reference signal received power threshold is too high and has no use value. The first measurement result or the second measurement result can be the measurement results of all different beams or reference signals or resources, or the best measurement result among them, or the worst measurement result among them.

[0121] Considering that if there are fewer first measurement results, even if the corresponding values ​​are higher, it cannot indicate that the actual quality is good, or if there are fewer second measurement results, even if the corresponding values ​​are lower, it cannot indicate that the actual quality is good, so when the number or proportion of better first measurement results is larger, or the number or proportion of worse second measurement results is larger, it is considered to determine the reference signal received power threshold corresponding to the candidate resource according to the first measurement result or the second measurement result. Optionally, it can be determined whether the first measurement result is better or whether the second measurement result is worse by comparison with a specific threshold.

[0122] The ratio of the first measurement results greater than or equal to the seventh threshold may be the ratio of the first measurement results greater than or equal to the seventh threshold to the total number of first measurement results of the corresponding beam direction / associated with the same reference signal / associated with the same TCI configuration / associated with the same terminal identifier, or the ratio of the first measurement results greater than or equal to the seventh threshold to the total number of all first measurement results.

[0123] The proportion of the second measurement results less than or equal to the ninth threshold may be the ratio of the second measurement results less than or equal to the ninth threshold to the total number of second measurement results of the corresponding beam direction / associated with the same reference signal / associated with the same TCI configuration / associated with the same terminal identifier, or the ratio of the second measurement results less than or equal to the ninth threshold to the total number of all second measurement results.

[0124] The fifth threshold, the sixth threshold, the seventh threshold, the eighth threshold, the ninth threshold, or the tenth threshold may be predefined by the protocol, or preconfigured by the network side device, or configured by the network side device, or determined by the terminal.

[0125] When the first measurement result or the second measurement result satisfies the first condition, the terminal determines the reference signal receiving power threshold corresponding to the candidate resource based on the first measurement result or the second measurement result, so that the reference signal receiving power threshold can correspond to the beam quality, which helps to improve the effectiveness of subsequent candidate resource determination.

[0126] Optionally, the terminal may select a reference signal received power threshold corresponding to the associated candidate resource in the threshold set according to the range to which the first measurement result or the second measurement result belongs. Multiple reference signal received power thresholds may be configured in the threshold set, and different first measurement results or second measurement results may correspond to different reference signal received power thresholds.

[0127] In some embodiments of the present application, the method may further include the following steps:

[0128] When the number or proportion of candidate resources included in the candidate resource set is less than or equal to the eleventh threshold, the terminal triggers an increase operation of the reference signal received power threshold corresponding to the candidate resources.

[0129] In an embodiment of the present application, when the reference signal receiving power threshold needs to be raised because the number of candidate resources in the candidate resource set does not meet the requirements during the resource exclusion process, the corresponding raising operation can be triggered, and the higher the value corresponding to the first measurement result, or the lower the value corresponding to the second measurement result, the higher the corresponding reference signal receiving power threshold raising value. If there are enough candidate resources when resources are excluded, the influencing factors of beam quality can be ignored, that is, the influence of beam quality will only be considered when there are fewer candidate resources, so as to maximize the transmission reliability. It can be understood that when the raising value of the reference signal receiving power threshold is higher, the reference signal receiving power threshold is also higher, and the candidate resources associated with it are less likely to be excluded, and they will be more likely to be selected as transmission resources. At this time, since the possibility of good beam quality is higher, the transmission is more likely to succeed.

[0130] The eleventh threshold may be predefined by the protocol, or preconfigured by the network side device, or configured by the network side device, or determined by the terminal.

[0131] Optionally, the raised value of the reference signal received power threshold is a value in a raised value set. The raised value set may be predefined by a protocol, or preconfigured by a network side device, or configured by a network side device, or determined by a terminal.

[0132] Optionally, when the number of candidate resources included in the candidate resource set is less than or equal to the eleventh threshold, after triggering the raising operation of the reference signal receiving power threshold corresponding to the candidate resources, if the value corresponding to the first measurement result is low, such as less than or equal to a certain threshold, or the value corresponding to the second measurement result is high, such as greater than or equal to a certain threshold, the reference signal receiving power threshold corresponding to the corresponding beam will not be raised.

[0133] In some embodiments of the present application, the method may further include the following steps:

[0134] When the first measurement result is less than or equal to the twelfth threshold, or the second measurement result is greater than or equal to the thirteenth threshold, the terminal excludes the corresponding candidate resource from the candidate resource set.

[0135] If the first measurement result is less than or equal to the twelfth threshold, or the second measurement result is greater than or equal to the thirteenth threshold, it can be considered that the beam quality is poor, and the corresponding candidate resources can be excluded in the resource selection process to ensure transmission reliability.

[0136] The terminal excludes the corresponding candidate resources in the resource selection process under one of the following circumstances:

[0137] step1 or before step1 or after step1, step1 corresponds to the step of determining the resource selection window and candidate resources;

[0138] Step 4 or before step 4 or after step 4, step 4 corresponds to the step of initializing the candidate resource set;

[0139] step5 or before step5 or after step5, step5 corresponds to a step of excluding possible candidate resources determined based on non-detection time slots;

[0140] Step 6 or before or after step 6, step 6 corresponds to a step of detecting and excluding reserved resources of other terminals based on sidelink control information (SCI);

[0141] Step7 or before step7 or after step7, step7 corresponds to the step of reporting the candidate resource set.

[0142] In some embodiments of the present application, the terminal determines the target object according to the first measurement result or the second measurement result, which may include the following steps:

[0143] The terminal determines a selection weight corresponding to the beam or the candidate resource or the candidate resource subset according to the first measurement result or the second measurement result, and determines a target object based on the selection weight.

[0144] In an embodiment of the present application, different first measurement results or second measurement results may correspond to different selection weights. The terminal may determine the selection weight corresponding to the beam or candidate resource or subset of candidate resources based on the first measurement result or the second measurement result, and may determine the target object based on the selection weight. That is, when the terminal selects a transmission resource or a transmission beam or collaborative information, it may select with different selection weights according to the first measurement result or the second measurement result, so that the candidate resource with a better corresponding first measurement result or a worse second measurement result is more likely to be selected as a transmission resource or a recommended resource, and the corresponding beam is more likely to be selected as a transmission beam or a recommended beam. The candidate resource with a worse corresponding first measurement result or a better second measurement result is more likely to be selected as a non-recommended resource, and the corresponding beam is selected as a non-recommended beam.

[0145] Optionally, the selection weight corresponding to the beam or candidate resource or candidate resource subset is reported by the physical layer of the terminal to the media access control (MAC) layer. That is, when the physical layer reports to the MAC layer, it determines the selection weight corresponding to the beam or candidate resource or candidate resource subset according to the first measurement result or the second measurement result, and the MAC layer selects the beam or resource according to different selection weights.

[0146] Optionally, the selection weight corresponding to the beam or candidate resource or candidate resource subset is determined by the MAC layer of the terminal according to the first measurement result or the second measurement result reported by the physical layer. That is, the physical layer reports the first measurement result or the second measurement result to the MAC layer, and the MAC layer determines the selection weight corresponding to the beam or candidate resource or candidate resource subset according to the first measurement result or the second measurement result, thereby selecting the beam or resource.

[0147] Optionally, the correspondence between candidate resources and selection weights, or the correspondence between candidate resource subsets and selection weights, or the correspondence between beams and selection weights is predefined by the protocol, or preconfigured by the network side device, or configured by the network side device, or determined by the terminal.

[0148] In some embodiments of the present application, the candidate resources do not include resources within the transmission window corresponding to the first beam;

[0149] The first beam satisfies at least one of the following conditions:

[0150] The first beam has no corresponding first measurement result or second measurement result;

[0151] The first measurement result corresponding to the first beam is less than or equal to a fourteenth threshold;

[0152] The second measurement result corresponding to the first beam is greater than or equal to the fifteenth threshold;

[0153] The number or ratio of the first measurement results or the second measurement results corresponding to the first beam is less than or equal to the sixteenth threshold.

[0154] In the embodiment of the present application, when the terminal initializes the candidate resource set, the resource selection window may include transmission windows corresponding to different beams. The first beam may be any one of the beams.

[0155] If the first beam does not have a corresponding first measurement result or a second measurement result, or the number or proportion of the first measurement result or the second measurement result corresponding to the first beam is small, it is considered that it is impossible to confirm whether the resources in the sending window corresponding to the first beam are reliable; if the first measurement result corresponding to the first beam is less than or equal to the fourteenth threshold, or the corresponding second measurement result is greater than or equal to the fifteenth threshold, it is considered that the quality of the resources in the sending window corresponding to the first beam is poor. Therefore, in the above case, the resources in the sending window corresponding to the first beam are not initialized as resources in the candidate resource set, or the resources in the sending window corresponding to the first beam are excluded from the candidate resource set. That is, when the first beam meets at least one of the above conditions, the candidate resources do not include the resources in the sending window corresponding to the first beam. This helps to improve the reliability of the candidate resources in the candidate resource set.

[0156] The fourteenth threshold, the fifteenth threshold, or the sixteenth threshold may be predefined by the protocol, or preconfigured by the network side device, or configured by the network side device, or determined by the terminal.

[0157] In some embodiments of the present application, the terminal determines the target object according to the first measurement result or the second measurement result, which may include the following steps:

[0158] The terminal determines the target object based on the first measurement result or the second measurement result and the first rule;

[0169] That is, the transmission resource or the recommended resource or the non-recommended resource may be preferentially selected from the candidate resources corresponding to the beam having the first measurement result or the second measurement result; or, the transmission resource or the recommended resource or the non-recommended resource may not be selected from the candidate resources corresponding to the beam having the first measurement result or the second measurement result; or, the transmission beam or the recommended beam or the non-recommended beam may be preferentially selected from the beam having the first measurement result or the second measurement result; or, the transmission beam or the recommended beam or the non-recommended beam may not be selected from the beam having the first measurement result or the second measurement result;

[0170] 6) preferentially selecting a transmission resource or a transmission beam or a recommended resource or a recommended beam or a non-recommended resource or a non-recommended beam based on a beam or a corresponding candidate resource without the first measurement result or the second measurement result;

[0171] That is, transmission resources or recommended resources or non-recommended resources may be preferentially selected from candidate resources corresponding to beams without the first measurement result or the second measurement result; or, transmission resources or recommended resources or non-recommended resources may not be selected from candidate resources corresponding to beams without the first measurement result or the second measurement result; or, transmission beams or recommended beams or non-recommended beams may be preferentially selected from beams without the first measurement result or the second measurement result; or, transmission beams or recommended beams or non-recommended beams may not be selected from beams without the first measurement result or the second measurement result;

[0173] 8) When there are candidate resources corresponding to the omnidirectional beam, the candidate resources corresponding to the omnidirectional beam are added to the candidate resources corresponding to any beam, and transmission resources or recommended resources or non-recommended resources are selected.

[0174] Among them, the seventeenth threshold or the eighteenth threshold or the nineteenth threshold or the twentieth threshold or the twenty-first threshold or the twenty-second threshold or the twenty-third threshold or the twenty-fourth threshold may be predefined by the protocol, or preconfigured by the network side device, or configured by the network side device, or determined by the terminal.

[0175] When the terminal selects a transmission resource or a transmission beam or a recommended resource or a recommended beam or a non-recommended resource or a non-recommended beam, the terminal makes a selection according to the first rule mentioned above, which helps to improve the side link transmission efficiency and side link transmission reliability.

[0176] In some embodiments of the present application, the first measurement result or the second measurement result may include a measurement result before the NA moment, or a measurement result after the NB moment;

[0177] Wherein, N is the resource selection triggering time n, or the first time n+T1 after the resource selection triggering time, or the time n+Y0 corresponding to the first candidate resource in the resource selection window after the resource selection triggering time, or the monitoring end time;

[0178] A includes at least the time for processing the measurement results;

[0179] B is an integer.

[0180] When the terminal triggers resource selection, the first measurement result or the second measurement result used includes the measurement result before the NA moment or the measurement result after the NB moment, and the used measurement results are limited, which helps to improve the validity of the used measurement results.

[0181] In some embodiments of the present application, the first measurement result or the second measurement result may satisfy a sixth condition, and the sixth condition may include at least one of the following:

[0182] The corresponding measurement window duration or number of samples or number of measurements is greater than or equal to the twenty-fifth threshold;

[0183] There is at least one corresponding detection opportunity;

[0184] Includes measurements from adjacent beams.

[0185] The beams corresponding to the resource selection window are [nT,n], or [nT,n+T1], or the first measurement result or the second measurement result after n-T0. When at least one of the sixth conditions mentioned above is met, the target object is determined according to the first measurement result or the second measurement result. When there is a beam without a corresponding first measurement result or second measurement result, the beam measurement of the relevant beam can be triggered after n. In addition, considering the timeliness, the results before nT or n-T0 are too early, and only the measurement results after that are considered. T and T0 are integers.

[0186] The twenty-fifth threshold may be predefined by the protocol, or preconfigured by the network side device, or configured by the network side device, or determined by the terminal.

[0187] In some embodiments of the present application, the method may further include the following steps:

[0188] When the second beam satisfies the seventh condition, the terminal performs the first behavior;

[0189] The seventh condition includes at least one of the following:

[0190] There is no corresponding first measurement result or second measurement result;

[0191] The measurement duration or the number of samples or the number of measurements is less than or equal to the twenty-sixth threshold;

[0192] The first behavior includes at least one of the following:

[0193] Randomly determine candidate resources;

[0194] Adjust the reference signal received power threshold corresponding to the second beam association time to be less than or equal to the twenty-seventh threshold;

[0195] Determine the time associated with the second beam as a non-detection time slot;

[0196] The candidate resource corresponding to the second beam is not used as a recommended resource;

[0197] The candidate resource initialization operation is not performed on the resources corresponding to the second beam.

[0198] In an embodiment of the present application, the second beam can be any beam of the terminal. When the second beam does not have a corresponding first measurement result or a second measurement result, or the measurement duration or the number of samples or the number of measurements is less than or equal to the twenty-sixth threshold, the terminal may not determine the candidate resources based on the first measurement result or the second measurement result, but may randomly determine the candidate resources, or adjust the corresponding reference signal receiving power threshold within the time associated with the second beam to be less than or equal to the twenty-seventh threshold, or determine the time associated with the second beam as non-detection time, such as non-monitored slots, and then exclude the associated candidate resources based on the method of excluding possible candidate resources at non-detection time during the resource selection process, or do not use the candidate resources corresponding to the second beam as recommended resources, or do not perform candidate resource initialization operations on the resources corresponding to the second beam.

[0199] The twenty-sixth threshold or the twenty-seventh threshold may be predefined by the protocol, or preconfigured by the network side device, or configured by the network side device, or determined by the terminal.

[0200] When the second beam satisfies the seventh condition, performing any of the above first actions helps to improve the side link transmission efficiency and side link transmission reliability.

[0201] When triggering resource selection, the terminal can trigger beam measurement of the corresponding beam.

[0202] In some embodiments of the present application, the method may further include the following steps:

[0203] The terminal determines whether to perform resource reselection or beam reselection according to the first measurement result or the second measurement result.

[0204] In an embodiment of the present application, when performing a re-evaluation or pre-emption check, the terminal may determine whether to perform resource reselection or beam reselection according to the first measurement result or the second measurement result. For example, when the first measurement result corresponding to the selected resource is less than or equal to the twenty-eighth threshold, or the corresponding second measurement result is greater than or equal to the twenty-ninth threshold, resource reselection or beam reselection is performed.

[0205] The terminal performs resource reselection or beam reselection, which helps to ensure the smooth transmission of the sidelink.

[0206] The technical solution provided in the embodiments of the present application has been described in detail above. For ease of understanding, it is further described below with specific examples.

[0207] Example 1: Joint beam measurement for resource selection

[0208] In FR2, the terminal's transmit beam is directional, and the beam quality of different beams may be different. Figure 8 In the example, beam 1 and beam 3 are beams that pass through a certain reflection path, while beam 2 is a direct beam. Assuming that the beam quality of beam 2 is the best without considering other obstructions, while the beam quality of beam 1 and beam 3 is poor, then without considering other interference, the reliability of data transmitted via beam 2 is the highest, while data transmitted via beam 1 or beam 3 may fail to demodulate. Furthermore, if there is other interference, data transmission on a beam with better beam quality will also increase the probability of successful reception, thereby improving transmission reliability. On the contrary, assuming that resources are associated with beams, if only the interference of other terminals is still considered to select resources with lower interference, a beam with poorer beam quality may be selected for transmission, which will result in lower transmission reliability and data demodulation failure. Therefore, in the FR2 scenario, it is necessary to consider combining the first measurement result or the second measurement result for resource selection, with the aim of trying to select beams with better quality or resources with better beam quality when the interference is roughly the same, or selecting resources with less interference when the beam quality is not much different.

[0209] For example, in the resource selection window, different beams correspond to different candidate resource subsets, such as Fig. 9 As shown, the candidate resource subsets corresponding to beam 1, beam 2, and beam 3 are Set 1, Set 2, and Set 3, respectively. Assume that the first measurement results of beam 1, beam 2, and beam 3 are result A, result B, and result C, respectively, where result A is lower than threshold 1, result B is higher than threshold 1, result C is lower than threshold 2, and threshold 1 is higher than threshold 2. At this time, there may be the following methods to realize beam selection in conjunction with the first measurement result, so as to select resources with less interference and better beam quality.

[0210] First, when initializing the candidate resource set, only the resources corresponding to the beams whose first measurement results are higher than threshold 1 are initialized into the candidate resource set, or after initializing the candidate resource set, the candidate resources corresponding to the beams whose first measurement results are lower than threshold 1 are excluded from the candidate resource set. In this case, the terminal can only select resources from Set 2. However, if the interference on beam 2 is high, the final transmission reliability may be low.

[0211] Second, when resources are excluded, different first measurement results correspond to different RSRP thresholds for candidate resources. For example, Set 2 corresponds to the highest RSRP threshold, which means that the transmission on beam 2 is more tolerant to interference. A higher RSRP threshold can increase the probability that the resource selected by the terminal is a candidate resource in the candidate resource subset Set 2.

[0212] Third, when the MAC layer selects resources from the candidate resource set reported by the physical layer, it no longer selects randomly, but selects according to certain selection weights, so that the probability of selecting candidate resources from different sets is different.

[0213] This solution is also applicable to the process in which the receiving end determines to indicate recommended resources or non-recommended resources to the sending end. Specifically, as the recipient of data, the receiving end can more accurately evaluate the interference that may be caused to data reception and measure the quality of the transmission beam than the sending end. Therefore, when the receiving end wants to indicate recommended resources or recommended beams or non-recommended resources or non-recommended beams to the sending end through collaborative information, the first measurement result or the second measurement result is combined to select resources or beams, so that beams or resources with higher transmission reliability can be selected.

[0214] Example 2: Determination of candidate resource subsets

[0215] There are two possible relationships between resources and beams. The first is that the selection of resources and beams is relatively independent, and the second is that each beam has a corresponding time window. Therefore, the resource selected also determines the corresponding transmission beam. In the FR2 scenario, if the relationship between resources and beams is the first one, the terminal can first determine the transmission resources and then the transmission beam. At this time, the resources in the resource selection window may be associated with any beam. If the relationship between resources and beams is the second one, it means that the candidate resources in the resource selection window have corresponding beams. At this time, if the resource selection window is still determined according to the existing rules, it may be composed of time windows corresponding to multiple beams in the end, that is, the candidate resource set can be divided into multiple candidate resource subsets. At this time, the terminal can perform resource selection operations based on the candidate resource set corresponding to the entire resource selection window, or it can perform resource selection operations based on the candidate resource subset.

[0216] When a candidate resource has an associated beam, the first measurement result or the second measurement result of the associated beam needs to be used to perform the resource selection process, which requires the first measurement result or the second measurement result of the corresponding beam in the detection window. Therefore, when the terminal determines the beam direction of the resource detection window, it needs to consider that the candidate resource in the resource selection window has a corresponding first measurement result or a second measurement result. For example, there are at least M time slots corresponding to the first measurement result or the second measurement result, or a first measurement result or a second measurement result of a detection opportunity.

[0217] The embodiment of the present application proposes a new resource selection mechanism in the FR2 scenario, which helps to improve the sidelink transmission efficiency and transmission reliability in FR2.

[0218] The sidelink resource selection method provided in the embodiment of the present application may be performed by a sidelink resource selection device.
