[0033] The technical solution provided by the embodiments of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0034] like Figure 2 FIG. 2 is a flow chart of a communication method 200 provided by an exemplary embodiment of the present application. The method 200 may be, but is not limited to, executed by a terminal, and may be specifically executed by hardware or software installed in the terminal. In this embodiment, the method 200 may at least include the following steps.

[0035] S210: The terminal determines a second number of target transmissions from the first set according to the first number.

[0036] The first set includes at least one first transmission.

[0037] Optionally, the first transmission may be a first transmission scheduled by the terminal, a first transmission expected by the terminal, or a first transmission scheduled by the terminal. That is, the first set may include one or more first transmissions scheduled, expected, or scheduled by the terminal.

[0038] Optionally, the first transmission may be but is not limited to a physical sidelink shared channel (Physical SideLink Shared Channel, PSSCH), a physical sidelink control channel (Physical SideLink Control Channel, PSCCH), a PSFCH, a SL-positioning reference signal (Positioning Reference Signal, PRS), a SL-synchronization signal block (Synchronization Signal and PBCH block, SSB), a SL-channel state information reference signal (Channel State Information Reference Signal, CSI-RS), a SL-phase tracking reference signal (Phase-tracking reference signal, PTRS, etc.).

[0039] The structure of the first transmission may include two types, such as one in which the first transmission occupies a third interlace and K3 (such as 1, 2, 5) first PRBs, and the other in which the first transmission occupies a first interlace. The first interlace is used to carry the first information, and the third interlace is not used to carry the first information, but can be used as a placeholder for the first transmission, to occupy a channel, or to meet the occupied channel bandwidth (OCB) requirement, etc. The first PRB is used to carry the first information.

[0040] Optionally, the first information may include but is not limited to hybrid automatic repeat request acknowledgement (HARQ-ACK) information, conflict information, data information, control information, etc.

[0041] Based on this, in some embodiments, for a transmission structure that occupies two PRBs, the terminal uses a first number related to the transmission restriction of the terminal to determine a second number of target transmissions from a first set, which can not only meet the transmission restriction or capability of the terminal, but also improve transmission reliability and improve the priority processing flow of SL transmissions such as PSFCH.

[0042] For example, in some embodiments, the first number may include but is not limited to at least one of the following 11)-17).

[0043] 11) A maximum number of first PRBs supported or capable of being transmitted by the terminal, where the first PRBs are used to carry first information.

[0044] 12) a maximum number of second PRBs supported or capable of being transmitted by the terminal, the second PRBs including the first PRBs and the third PRBs, the third PRBs not being used to carry the first information. It is understood that the third PRBs may be used as a placeholder for the first transmission, for occupying a channel, or for satisfying an occupied channel bandwidth (OCB) requirement, etc.

[0045] 13) a maximum number of first interlaces supported or capable of being transmitted by the terminal, where the first interlace is used to carry first information, such as HARQ-ACK information, collision information, data information, control information, etc.

[0046] 14) A maximum number of second interlaces supported or capable of being transmitted by the terminal, where the second interlaces include the first interlace and a third interlace.

[0047] 15) The maximum number of third interlaces supported or capable of being transmitted by the terminal.

[0048] 16) The maximum number of resource block sets (RB sets) supported or capable of being transmitted by the terminal.

[0049] 17) a first transmission resource or a maximum number of first transmissions supported or capable of being transmitted by the terminal, wherein the first transmission resource includes at least one of a PRB, an interlace, and an RB set occupied by the first transmission.

[0050] Optionally, the PRB occupied by the first transmission may include the first PRB but not the third PRB; similarly, the interlace occupied by the first transmission may include the first interlace but not the third interlace.

[0051] It can be understood that, through the first number provided in the above 11)-17), the terminal can meet the terminal transmission restriction when performing the target transmission determined according to the first number, thereby improving the transmission reliability.

[0052] It is worth noting that the first quantity described in the above 11)-17) can be configured by protocol agreement, high-level instructions, terminal autonomous reporting, etc.

[0053] Based on this, in some embodiments, the first quantity can be configured or reported based on a predetermined resource granularity, and the predetermined resource granularity may include but is not limited to one or more of bandwidth, bandwidth combination, frequency range (FR), terminal, feature set, carrier, bandwidth part (Bandwidth Part, BWP), resource pool, channel, sub-channel, and RB set.

[0054] When the predetermined resource granularity is bandwidth, it can be understood that the first quantity is configured or reported for one bandwidth, each bandwidth, multiple bandwidths, or some bandwidths.

[0055] When the predetermined resource granularity is a bandwidth combination, it can be understood that the first quantity is configured or reported for one bandwidth combination, each bandwidth combination, multiple bandwidth combinations, or some bandwidth combinations.

[0056] When the predetermined resource granularity is a frequency domain range, it can be understood that the first quantity is configured or reported for one frequency domain range, each frequency domain range, multiple frequency domain ranges, or some frequency domain ranges. Optionally, the frequency domain range can be FR1, FR2-1, FR2-2, etc.

[0057] When the predetermined resource granularity is a terminal, it can be understood that the first quantity is configured or reported for one terminal or each terminal or multiple terminals or some terminals.

[0058] When the predetermined resource granularity is a feature set, it can be understood as configuring or reporting the first quantity for one feature set or each feature set or multiple feature sets or certain feature sets. Among them, the feature set can be understood as the structure of the first transmission. Taking the PFSCH as an example, the structure of the PFSCH can include two types, one is that each PFSCH transmission occupies a third interlace and K3 (such as 1, 2, or 5) first PRBs, and the other is that each PFSCH occupies a first interlace.

[0059] When the predetermined resource granularity is a carrier, it can be understood that the first quantity is configured or reported for one carrier or each carrier or multiple carriers or some carriers.

[0060] When the predetermined resource granularity is a bandwidth part, it can be understood that the first quantity is configured or reported for one bandwidth part or each bandwidth part or multiple bandwidth parts or some bandwidth parts.

[0061] When the predetermined resource granularity is a resource pool, it can be understood that the first quantity is configured or reported for one resource pool or each resource pool or multiple resource pools or some resource pools.

[0062] When the predetermined resource granularity is a channel, it can be understood that the first quantity is configured or reported for one channel or each channel or multiple channels or some channels.

[0063] When the predetermined resource granularity is a subchannel, it can be understood that the first quantity is configured or reported for one subchannel or each subchannel or multiple subchannels or some subchannels.

[0064] When the predetermined resource granularity is RB set, it can be understood that the first quantity is configured or reported for one RB set or each RB set or multiple RB sets or some RB sets.

[0065] S220: Perform SL transmission based on the second number of target transmissions.

[0066] Wherein, when the terminal performs SL transmission of the second number of target transmissions, it may also, but is not limited to, perform operations such as power control on the second number of target transmissions to ensure the reliability of the target transmissions.

[0067] In this embodiment, the second number of target transmissions is determined by the first number related to the transmission restriction, thereby enabling the target transmission determined by the terminal to be related to the transmission restriction, thereby ensuring that the number of SL transmissions such as PSFCH does not exceed the UE capability, and improving the priority processing flow of SL transmissions such as PSFCH.

[0068] like Figure 3 FIG. 3 is a flow chart of a communication method 300 provided by an exemplary embodiment of the present application. The method 300 may be, but is not limited to, executed by a terminal, and may be specifically executed by hardware or software installed in the terminal. In this embodiment, the method 300 may at least include the following steps.

[0069] S310: The terminal determines a second number of target transmissions from the first set according to the first number.

[0070] S320: Perform SL transmission based on the second number of target transmissions.

[0071] The first set includes at least one first transmission, and the first number is related to the transmission restriction of the terminal.

[0072] It can be understood that the relevant features of S310-S320 can refer to the description in the aforementioned method embodiment 200. Of course, in addition to referring to the description in the aforementioned method embodiment 200, in some implementations, when the terminal determines the second number of target transmissions from the first set according to the first number, the terminal can determine the second number of target transmissions from the first set according to the priority or priority value of the first transmission in the first set and the first number. For example, the second number of target transmissions can be determined from the first set according to the first number and the ascending or descending order of the priority of the first transmission in the first set, etc., which is not limited here.

[0073] Based on this, in order to further improve communication reliability, this embodiment also limits or stipulates the number of target transmissions (ie, the second number) and the like.

[0074] For example, the second number may include but is not limited to at least one of the following 21)-23).

[0075] 21) The second number is N / K3, where N is the first number, and K3 is the number of first PRBs occupied by the first transmission, such as 1, 2, or 5.

[0076] 22) The second quantity is the first quantity.

[0077] 23) The second number is the difference between the first number and the predetermined value. The predetermined value can be obtained according to at least one of the type and structure of the target transmission, the number of third PRB groups occupied by the target transmission, the number of third interlaces occupied by the target transmission, and the number of RB sets occupied by the target transmission. For example, the predetermined value may be 0 or non-existent, or, when each RB set has a third interlace, the predetermined value is the number of RB sets.

[0078] For another example, the second number of target transmissions may, but is not limited to, satisfy at least one of the following 31)-36).

[0079] 31) The first PRBs occupied by the second number of target transmissions are located on the first number of first interlaces, wherein the first number of first interlaces are determined based on the first set.

[0080] 32) The number of second PRBs occupied by the second number of the target transmissions does not exceed the first number;

[0081] 33) The first PRBs occupied by the second number of the target transmissions are on a third number of second interlaces, and the third number is determined based on at least one of the first number, the number of third interlaces occupied by the first transmission, and the number of RB sets occupied by the first transmission, wherein the third number of second interlaces is determined based on the first set.

[0082] 34) The number of first PRBs occupied by the first interlace where the second number of the target transmissions are located is not greater than the first number.

[0083] 35) The number of third interlaces occupied by the second number of target transmissions is not greater than the first number.

[0084] 36) The number of RB sets in which the second number of target transmissions are located is not greater than the first number.

[0085] In this case, in some implementations, the terminal may perform the step of determining the second number of target transmissions from the first set according to the first number when determining that the first condition is satisfied. The first condition includes at least one of the following 41)-50).

[0086] Condition 1: The number of first PRBs occupied by the first transmission in the first set is greater than the first number.

[0087] In addition, Condition 1 may be applicable to but is not limited to situations where the first number includes the maximum number of first PRBs supported or capable of being transmitted by the terminal, and each transmission occupies 1 third interlace and K3 first PRBs.

[0088] Based on this, in one implementation, when the condition 1 is met, the terminal can determine a second number of target transmissions from the first set according to the first number, and the second number is N / K3.

[0089] Condition 2: The number of interlaces where the first PRBs occupied by the first transmission in the first set are located is greater than the first number.

[0090] Among them, condition 2 may be applicable to but not limited to the situation where the first number includes the maximum number of first interlaces supported or capable of being transmitted by the terminal, and each transmission occupies 1 third interlace and K3 first PRBs.

[0091] Based on this, in one implementation, when the condition 2 is met, the terminal may determine a second number of target transmissions from the first set according to the first number, and the first PRBs occupied by the second number of target transmissions are located on the first number of first interlaces. The first number of first interlaces is determined based on the first set, such as determining the first number of first interlaces from the interlaces occupied by the target transmissions of the first set.

[0092] Condition 3: The number of second PRBs occupied by the first transmission in the first set is greater than the first number.

[0093] In addition, Condition 3 may be applicable to but is not limited to situations where the first number includes the maximum number of second PRBs supported or capable of being transmitted by the terminal, and each transmission occupies 1 third interlace and K3 first PRBs or each transmission occupies 1 first interlace, etc.

[0094] Based on this, in one implementation, when the condition 3 is met, the terminal can determine a second number of target transmissions from the first set based on the first number, and the second number can be the maximum number of first transmissions in the first set and the number of second PRBs occupied by the second number of target transmissions does not exceed the first number.

[0095] In another implementation method, if the terminal determines that condition 3 is met and the second condition is met, it may also discard or preferentially discard the third PRB occupied by the target transmission or the PRB occupied by the third interlace that meets the second condition, thereby ensuring that the PRB occupied by the target transmission matches the terminal capability.

[0096] The second condition may include but is not limited to at least one of the following a)-c).

[0097] a) The third PRB and the first PRB occupied by the first transmission in the first set are within the same bandwidth, such as the same 1 MHz bandwidth.

[0098] b) The PRB occupied by the third interlace and the first PRB occupied by the first transmission in the first set are within the same bandwidth, such as the same 1 MHz bandwidth.

[0099] c) The bandwidth between the lowest PRB and the highest PRB occupied by the first transmission in the first set meets predetermined requirements, such as the bandwidth between the lowest PRB and the highest PRB occupied by the first transmission in the first set exceeds 16 MHz, meets the OCB requirements or exceeds 80% of the channel bandwidth.

[0100] The lowest PRB may be the first PRB or the third PRB, and similarly, the highest PRB may be the first PRB or the third PRB.

[0101] Condition 4: The number of interlaces where the second PRBs occupied by the first transmission in the first set are located is greater than the first number.

[0102] Among them, condition 4 may be applicable to but not limited to the situation where the first number includes the maximum number of second interlaces supported or capable of being transmitted by the terminal, and each transmission occupies 1 third interlace and K3 first PRBs.

[0103] Based on this, in one implementation, when condition 4 is met, the terminal may determine a second number of target transmissions from the first set according to the first number, and the first PRBs occupied by the second number of target transmissions are on a third number of second interlaces. The third number of second interlaces is determined based on the first set.

[0104] Optionally, the third number may be determined according to at least one of the first number, the number of second interlaces occupied by the first transmission, and the number of RB sets occupied by the first transmission. For example, in the case where the third interlace is discarded, the third number is the second number. For another example, in the case where the third interlace is not discarded, the third number is the difference between the second number and the number of third interlaces occupied by the first transmission. For another example, if the interlaces are numbered on one carrier, the third number may be determined according to the number of RB sets occupied by the first transmission.

[0105] It can be understood that the terminal may also discard the third interlace when the second condition is met, thereby ensuring that the PRBs occupied by the target transmission match the terminal capability. The description of the second condition may refer to the description in the aforementioned condition 3, which will not be repeated here.

[0106] Condition 5: The number of first transmissions or first transmission resources in the first set is greater than the first number.

[0107] It is understandable that one or more third PRBs or third interlaces are not counted as one or more first transmission resources. For example, the terminal is scheduled to transmit two PSFCHs, and the two target transmissions occupy a total of 1 third interlace and 2*K3 PRBs, then the number of first transmission resources occupied by the two PSFCHs is 2.

[0108] In addition, Condition 5 may be applicable to but is not limited to the situation where the first number includes the first transmission resources or the maximum number of first transmissions supported or capable of being transmitted by the terminal, and each transmission occupies 1 third interlace and K3 first PRBs, or the situation where each first transmission occupies 1 first interlace, etc.

[0109] Condition 6: The number of first transmission resources or first transmissions in the first set plus a predetermined value is greater than the first number.

[0110] The predetermined value may be obtained according to at least one of the type and structure of the target transmission, the number of third PRB groups occupied by the target transmission, the number of third interlaces occupied by the target transmission, and the number of RB sets occupied by the target transmission. For example, the predetermined value may be 0 or not exist, or, when each RB set has a third interlace, the predetermined value is the number of RB sets.

[0111] It is understandable that one or more third PRBs or third interlaces are not counted as one or more first transmission resources. For example, the terminal is scheduled to transmit two PSFCHs, and the two target transmissions occupy a total of 1 third interlace and 2*K3 PRBs, then the number of first transmission resources occupied by the two PSFCHs is 3.

[0112] In addition, Condition 6 may be applicable to but is not limited to the situation where the first number includes the first transmission resources supported or capable of being transmitted by the terminal or the maximum number of first transmissions, and each transmission occupies 1 third interlace and K3 first PRBs, or the situation where each first transmission occupies 1 first interlace, etc.

[0113] Based on this, in one implementation, when the condition 6 is met, the terminal may determine a second number of target transmissions from the first set according to the first number, and the second number is the first number or the difference between the first number and a predetermined value, and the first PRBs occupied by the second number of target transmissions are on a third number of second interlaces. The third number of second interlaces is determined based on the first set.

[0114] Condition 7: The number of PRBs occupied by the second interlace where the first transmission in the first set is located is greater than the first number.

[0115] Among them, condition 7 may be applicable to but not limited to the situation where the first number includes the maximum number of first PRBs supported or capable of being transmitted by the terminal, or the maximum number of second PRBs supported or capable of being transmitted by the terminal, and each first transmission occupies 1 first interlace, etc.

[0116] Based on this, in one implementation, when condition 7 is met, the terminal can determine a second number of target transmissions from the first set based on the first number, and the number of first PRBs occupied by the first interlace where the second number of target transmissions are located is not greater than the first number.

[0117] Condition 8: The number of second interlaces where the first transmission in the first set is located is greater than the first number.

[0118] Among them, condition 8 may be applicable to but not limited to the situation where the first number includes the maximum number of first interlaces supported or capable of being transmitted by the terminal, or the first number includes the maximum number of second interlaces supported or capable of being transmitted by the terminal, and each first transmission occupies 1 first interlace, etc.

[0119] Condition 9: The number of third interlaces occupied by the first transmissions in the first set is greater than the first number.

[0120] For example, when condition 9 is met, the terminal may determine a second number of target transmissions from the first set according to the first number, and the number of third interlaces occupied by the second number of target transmissions is not greater than the first number.

[0121] If the interlaces are numbered on one carrier, then the number of the second interlaces where the first transmission is located needs to take into account the number of RB sets occupied by the first transmission.

[0122] Condition 10: the number of RB sets occupied by the first transmission in the first set is greater than the first number.

[0123] Among them, condition 10 may be applicable to but not limited to the situation where the first number includes the maximum number of RB sets supported or capable of being transmitted by the terminal, and each transmission occupies 1 third interlace and K3 first PRBs, or each first transmission occupies 1 first interlace, etc.

[0124] Based on this, in one implementation, when condition 10 is met, the terminal may determine a second number of target transmissions from the first set according to the first number, and the number of RB sets where the second number of target transmissions are located is not greater than the first number.

[0125] In this embodiment, on the basis of determining the second number of target transmissions from the first set according to the first number, further restrictions or specifications are imposed on the number of target transmissions, the conditions satisfied by the second number of target transmissions, etc., which can further improve the priority processing flow of related transmissions, ensure that the target transmissions meet the terminal transmission restrictions or capabilities, and effectively improve the reliability of communication transmissions.

[0126] like Figure 4 FIG. 4 is a flow chart of a communication method 400 provided by an exemplary embodiment of the present application. The method 400 may be, but is not limited to, executed by a terminal, and may be specifically executed by hardware or software installed in the terminal. In this embodiment, the method 400 may at least include the following steps.

[0127] S410: The terminal determines a fourth number of second transmissions from the second set.

[0128] The terminal has the capability of sending or receiving on a non-continuous RB set, or the terminal does not have the capability of sending or receiving on a non-continuous RB set, which is not limited in this embodiment.

[0129] The second set includes at least one third transmission, and the at least one third transmission is located on multiple RBsets, such as multiple continuous RB sets or non-continuous RB sets. In this regard, when determining the second transmission, the terminal may consider whether the terminal has the ability to send or receive on a continuous RB set. If the terminal has the ability to send or receive on a non-continuous RB set, then the terminal may determine the second transmission from a continuous or non-continuous RB set. Otherwise, the terminal determines the second transmission from a continuous RB set. This can further improve the priority processing process of related transmissions, so that the terminal's capabilities match the determined second transmission, thereby improving communication reliability.

[0130] Optionally, the third transmission may be SL transmission, uplink (UP Link, UL) transmission, downlink (Down Link, UL) transmission, etc.

[0131] It is also worth noting that the "transmission" mentioned in the context of this application includes sending or receiving, such as SL transmission includes SL receiving or SL sending, etc.

[0132] Of course, the third transmission may be a third transmission scheduled by the terminal, a third transmission expected by the terminal, or a third transmission scheduled by the terminal, that is, the first set may include one or more third transmissions scheduled, expected, or scheduled by the terminal.

[0133] like Figure 5a FIG. 5 is a flow chart of a communication method 500 provided by an exemplary embodiment of the present application. The method 500 may be, but is not limited to, executed by a terminal, and may be specifically executed by hardware or software installed in the terminal. In this embodiment, the method 500 may at least include the following steps.

[0134] S510: The terminal determines a fourth number of second transmissions from the second set.

[0135] The second set includes at least one third transmission, and the at least one third transmission is located on multiple RB sets.

[0136] It can be understood that the relevant features of S510 can refer to the relevant description in the aforementioned method embodiment 400. Of course, in this embodiment, in addition to referring to the relevant description in the aforementioned method embodiment 400, please refer to Figure 5a In some embodiments, the process of the terminal determining a fourth number of second transmissions from the second set may include S511, the content of which is as follows.

[0137] S511: The terminal determines a fourth number of second transmissions from the second set according to the second information.

[0138] The second information includes at least one of the following 401)-414).

[0139] 401) The priority of the third transmission.

[0140] For example, in the case where the terminal has the capability of receiving or sending non-contiguous RB sets, the terminal may determine the fourth number of second transmissions from the second set according to the ascending or descending order of the priority of the third transmissions.

[0141] For another example, when the terminal does not have the capability to receive or send non-continuous RB sets, the terminal may determine the fourth number of second transmissions from one or continuous RB sets, wherein the one or continuous RB sets include the third transmission with the highest priority in the second set.

[0142] Optionally, when determining the fourth number of second transmissions from one or consecutive RB sets, the terminal may determine the fourth second transmission according to the number of third transmissions included in the one or consecutive RB sets.

[0143] Alternatively, the terminal determines the fourth number of second transmissions within the one or continuous RB sets according to an ascending order or a descending order of priorities.

[0144] Alternatively, the terminal determines M1 third transmissions according to the ascending or descending order of priority, until the third transmission with the highest priority and the M1 third transmissions meet the transmission capacity or / limit of the terminal, and determines the third transmission with the highest priority and the M1 third transmissions as the fourth second transmission. The M1 third transmissions are located on one or continuous RB sets selected above, or the RB set where the M1 third transmissions are located and the one or continuous RB sets selected above can continue to constitute a continuous RB set.

[0145] Alternatively, the terminal determines M2 third transmissions from the second set according to the ascending or descending order of the priority of the third transmissions, and then determines a fourth number of second transmissions in one or continuous RB sets from the M2 third transmissions.

[0146] 402) The number of the third transmission.

[0147] For example, when the terminal does not have the capability to receive or transmit non-continuous RB sets, the terminal determines the fourth number of second transmissions from one or continuous RB sets, wherein the number of third transmissions in the one or continuous RB sets satisfies at least one of the following a)-b).

[0148] a) The number of the third transmissions in the one or consecutive RB sets is the largest number in the RBsets occupied by the second set. For example, the RB sets occupied by the second set are RB set 1, RB set 2, and RB set 3, respectively, and the number of third transmissions on RBset 2 is the largest, then the terminal can determine the fourth number of second transmissions from RB set 2.

[0149] b) The number of third transmissions with a specific priority in the one or continuous RB sets is the largest among the RB sets occupied by the second set.

[0150] For example, the RB sets occupied by the second set are RB set 1, RB set 2, and RB set 3, and the number of third transmissions with specific priorities on RB set 2 is the largest. Then, the terminal may determine the fourth number of second transmissions from RB set 2.

[0151] The specific priority may be the highest priority among the third transmissions included in the first set, or may be the priority indicated by the network side or agreed upon by the protocol, etc.

[0152] Optionally, when the specific priority is the highest priority, if there are two or more consecutive RBsets in which the number of third transmissions with the specific priority is the same, then the fourth number of second transmissions can be determined based on one or more consecutive RB sets with the largest number of third transmissions with the second highest priority, that is, it is determined that the fourth number of second transmissions includes one or more consecutive RB sets that include the largest number of third transmissions with the highest priority and the largest number of third transmissions with the second highest priority, and so on, and the fourth number of second transmissions is determined according to the descending order of priority and the largest number of third transmissions with the corresponding priority.

[0153] For another example, the terminal selects one or continuous RB set including the largest number of third transmissions with the highest priority, and the terminal determines the fourth number of second transmissions in the one or continuous RB set according to ascending or descending order of priority.

[0154] For another example, the terminal selects the third transmission with the largest number and the highest priority on one or continuous RB set. Further, the terminal determines M1 third transmissions according to the ascending / descending order of priority until the third transmission with the largest number and the M1 third transmissions meet the UE capability / limitation, and the third transmission with the highest priority and the M1 third transmissions are the fourth number of second transmissions determined. Optionally, the M1 third transmissions are the third transmissions with the largest number in the corresponding priority.

[0155] The M1 third transmissions are located on the one or continuous RB sets selected above, or the RB sets where the M1 third transmissions are located and the one or continuous RB sets selected above can continue to constitute a continuous RB set.

[0156] c) The number of third transmissions satisfying UE capability / limitation in the one or continuous RB sets is the largest in the RB sets occupied by the second set.

[0157] For example, the RB sets occupied by the second set are RB set 1, RB set 2, and RB set 3, and the number of third transmissions that meet UE capabilities on RBset 2 is the largest, then the terminal can determine the fourth number of second transmissions from RB set 2.

[0158] The terminal capability may include the number of target transmissions that the terminal can transmit or the maximum transmission power allowed by the terminal.

[0159] 403) Listen Before Talk (LBT) results.

[0160] For example, the terminal may select the fourth number of second transmissions from the third transmissions on one RB set or consecutive RB sets in which LBT is successful.

[0161] 404) A channel busy rate of the RB set where the third transmission is located.

[0162] For example, the terminal may select the fourth quantity of second transmissions from the third transmission on an RB set whose channel busy rate is the lowest or below a certain threshold; or, the terminal may select the fourth quantity of second transmissions from the third transmission on continuous RB sets, wherein the continuous RB sets include at least one RB set whose channel busy rate is the lowest or below a certain threshold.

[0163] 405) A continuous LBT failure (Consistent-LBT-Failure, C-LBT-F) result of the RB set where the third transmission is located.

[0164] For example, the terminal may select the fourth quantity second transmission from the third transmission on one or consecutive RB sets, wherein C-LBT-F does not occur on the one or consecutive RB sets, or the C-LBT-F timer is minimum or the C-LBT-F timer is less than a certain threshold, or C-LBT-F does not occur on the target RB set, or the C-LBT-F timer is minimum or the C-LBT-F timer is less than a certain threshold.

[0165] 406) The fourth number of second transmissions includes at least one third transmission on a first RB set, and the first RB set is an RB set or continuous RB sets occupied by the third transmission in the second set.

[0166] 407) the number of RB sets where the third transmission is located;

[0167] For example, the terminal may select the fourth number of second transmissions from the third transmissions in the continuous RB set containing the largest number of RB sets.

[0168] 408) An identifier (ID) of the RB set where the third transmission is located.

[0169] For example, the terminal may select the fourth number of second transmissions from an RB set with the largest or smallest ID; or, the terminal may select the fourth number of second transmissions from continuous RB sets including an RB set with the largest or smallest ID.

[0170] 409) The frequency domain position of the third transmission.

[0171] For example, the terminal may select the fourth number of second transmissions from an RB set with the highest or lowest frequency domain position; or, the terminal may select the fourth number of second transmissions from continuous RB sets including an RB set with the highest or lowest frequency domain position.

[0172] 410) Whether the RB set occupied by the third transmission includes a second RB set, where the second RB set is an RB set where the third transmission corresponding to at least one COT initiating UE is located.

[0173] For example, the terminal selects the fourth number of second transmissions from the continuous RB sets including the second RB set. Of course, if there are multiple continuous RB sets including the second RB set, then the terminal can further select the fourth number of second transmissions based on the priority and quantity of the third transmissions on the continuous RB sets.

[0174] 411) Whether the third transmission is located in the channel occupancy time (COT) or the remaining COT occupied RB set.

[0175] For example, the terminal may select the fourth number of second transmissions from third transmissions within the RB set occupied by the COT or the remaining COT.

[0176] 412) Whether the RB set occupied by the third transmission adopts a specified LBT type or a shared channel mode for channel access.

[0177] Among them, the specified LBT type can be Type 2, Type 2a, Type 2b, Type 2c, etc.

[0178] For example, the terminal may select a fourth number of second transmissions from the third transmissions in the RB set that uses a specified LBT type or a shared channel manner for channel access.

[0179] 413) Whether the third transmission includes third information, the third information is used to convert the non-continuous RB set into a continuous RB set. The third information can be a third interlace, a dummy PSFCH, etc., which is not limited here.

[0180] For example, the terminal sends the third information on non-continuous RB sets, so that the RB sets occupied by the fourth number of second transmissions are continuous.

[0181] 414) A specific RB set configured by a higher layer or the network.

[0182] For example, the terminal may select the fourth number of second transmissions from a specific RB set or continuous RB sets including the specific RB set.

[0183] Based on this, in one implementation, after the terminal determines the fourth number of second transmissions from the second set, assuming that the second transmissions are all target transmissions, and there is a time domain overlap between the fourth number of target transmissions and the fifth number of target receptions, the terminal may perform at least one of operations 1 to 4 to resolve the transmission conflict problem caused by the time domain overlap. It is worth noting that the target reception mentioned in the context of this application may include but is not limited to SL reception or UL reception.

[0184] Operation 1: If the highest priority of the fourth number of target transmissions is higher than the highest priority of the fifth number of target receptions, determine that the target transmission is the fourth number of target transmissions.

[0185] Operation 2: If the highest priority of the fourth number of target transmissions is lower than the highest priority of the fifth number of target receptions, determine the target transmission as the fifth number of target receptions.

[0186] Operation 3: If the priority of at least one target transmission among the fourth number of target transmissions is higher than the first threshold, determine the target transmission to be the fourth number of target transmissions.

[0187] Operation 4: If the priority of at least one target reception among the fifth number of target receptions is higher than the second threshold, determine the target transmission as the fifth number of target receptions.

[0188] It can be understood that by executing any one of the aforementioned operations 1 to 4, the time domain conflict problem that may exist between target reception and target transmission can be effectively solved, thereby ensuring the communication quality.

[0189] In another implementation manner, after the terminal determines the fourth number of second transmissions from the second set, the terminal may further perform LBT and determine the target transmission according to the LBT result.

[0190] Optionally, the terminal may determine the target transmission method according to the LBT result, including at least one of the following methods 1 to 3.

[0191] Mode 1: When the LBT of all RB sets where the fourth number of second transmissions are located is successful, the fourth number of second transmissions are determined as the target transmissions.

[0192] Mode 2: When there is at least one LBT failure or success in the RB set where the second transmission is located, the target transmission is determined according to the first rule. The determining the target transmission according to the first rule includes at least one of the following 51)-55).

[0193] 51) Determine the target transmission from the second transmission on the RB set where LBT is successful according to the second information.

[0194] For example, in the case where the second information is the priority of the second transmission, the terminal may determine the target transmission from the second transmissions on the RB set where the LBT is successful in descending or ascending order of the priority of the second transmission.

[0195] For another example, when the second information includes the number of the second transmissions, the terminal determines the target transmission from a target RBset, and the target RB set is an RB set having the largest number of second transmissions among the RB sets in which the LBT is successful.

[0196] 52) When the second transmission in the LBT successful RB set overlaps with the fifth number of target receptions in the time domain, and the highest priority of the second transmission in the LBT successful RB set is higher than the highest priority among the fifth number of target receptions, the terminal determines the second transmission in the LBT successful RB set as the target transmission, or determines at least part of the second transmission from the LBT successful RB set as the target transmission based on the second information. The second information includes the priority of the second transmission, the number of the second transmission, etc.

[0197] 53) When the second transmission in the RB set where LBT succeeds has a time domain overlap with the fifth number of target receptions, and the highest priority of the second transmission in the RB set where LBT succeeds is lower than the highest priority of the fifth number of target receptions, the fifth number of target receptions is determined to be the target transmission.

[0198] 54) When the second transmission within the LBT successful RB set overlaps with the fifth number of target receptions in the time domain, and the priority of at least one of the first transmissions within the LBT successful RB set is higher than a first threshold, the second transmission within the LBT successful RB set is determined as the target transmission, or the target transmission is determined from the second transmissions within the LBT successful RB set according to the priority or quantity of the second transmissions.

[0199] 55) When the second transmission in the RB set where LBT is successful overlaps with the fifth number of target receptions in the time domain, and the priority of at least one of the fifth number of target receptions is higher than the second threshold, the fifth number of target receptions is determined to be the target transmission.

[0200] Mode 3: When LBT of all RB sets where the fourth number of second transmissions are located fails and there is a time domain overlap between the fourth number of second transmissions and the fifth number of target receptions, determine the fifth number of target receptions as the target transmissions.

[0201] In addition to the aforementioned terminal determining the target transmission after determining the fourth number of second transmissions from the second set to improve communication reliability, in one implementation, the terminal may also perform LBT before determining the fourth number of second transmissions, and then determine the fourth number of second transmissions from the second set based on the LBT results.

[0202] Optionally, in this embodiment, the manner in which the terminal determines a fourth number of second transmissions from the second set according to the LBT result may include but is not limited to at least one of the following manners 1 to 3.

[0203] Mode 1: when LBT of all RB sets in which the third transmission in the second set is located is successful, the fourth number of second transmissions is determined based on the third transmission in the RB set in which LBT is successful.

[0204] Mode 2: When there is at least one RB set in the second set where the LBT of the third transmission is located fails or succeeds, the terminal determines a fourth number of second transmissions from the second set according to a second rule.

[0205] The manner in which the terminal determines the fourth number of second transmissions from the second set according to the second rule may include at least one of the following:

[0206] 61) In a case where the highest priority among the third transmissions within the LBT successful RB set is higher than the highest priority among the fifth number of target receptions, the fourth number of second transmissions is determined based on the third transmission within the LBT successful RB set.

[0207] 62) In the case where the highest priority among the third transmissions within the LBT successful RB set is lower than the highest priority among the fifth number of target receptions, the step of determining the fourth number of second transmissions from the second set and determining the fifth number of target receptions as target transmissions are not performed.

[0208] 63) In a case where there is at least one third transmission whose priority is higher than a third threshold among the third transmissions in the RB set where LBT is successful, the fourth number of second transmissions is determined based on the third transmission in the RB set where LBT is successful.

[0209] 64) In the event that there is at least one reception whose priority among the fifth number of target receptions is higher than a fourth threshold, the step of determining the fourth number of second transmissions from the second set and determining the fifth number of target receptions as the target transmissions are not performed.

[0210] Method 3: When the LBT of all RB sets where the third transmission in the second set is located fails, and there is a time domain overlap between the third transmission in the second set and the fifth number of target receptions, the step of determining the fourth number of second transmissions from the second set and determining the fifth number of target receptions as the target transmissions are not performed.

[0211] In this embodiment, by further improving the priority processing process of transmissions such as PSFCH in unlicensed frequency band sidelink transmissions (Sidelink Unlicensed, SLU), the terminal's clear transmission behavior is clarified, thereby ensuring the reliability of communication transmission.

[0212] The communication method provided in the embodiment of the present application can be executed by a communication device. In the embodiment of the present application, the communication device provided in the embodiment of the present application is described by taking the communication device executing the communication method as an example.

[0213] Based on the description in the foregoing method embodiment 300, the selection process of the second transmission is exemplarily described below by taking the third transmission being PSFCH as an example and the terminal not having the capability of non-continuous RB set transmission as an example.

[0214] Example 1

[0215] The terminal may first select the PSFCH according to a conventional or normal priority processing flow, and then select the target transmission from the selected continuous RB set.

[0216] For example, Figure 5b As shown, after the terminal performs the conventional or normal priority processing process, the PSFCH to be sent is located on RB set 0, RB set 2, and RB set 3. Since RB set 0, RB set 2, and RB set 3 are not continuous, the terminal can select the PSFCH on the most RB sets that can be continuously sent for transmission, that is, continuous RB set 2 and RB set 3.

[0217] Alternatively, the terminal may also select the RB set where the PSFCH with the highest priority is located, and if this RB set has a connected RB set, send them together; if not, send them separately. For example, if the PSFCH with the highest priority is located in RBset2, the PSFCHs on RB set2 and RB set3 are sent together. And if the PSFCH with the highest priority is located in RBset0, only the PSFCH on RB set0 is sent. At this time, if the PSFCH with the highest priority is located in different RB sets, then in this case, the RB set where the PSFCH with the largest number of priorities is located may be considered, and priority may also be given to whether it has a connected RB set or a RB set with the second highest priority (or a priority higher than a certain level, such as 2, 3, 4, 5, etc.) and the largest number, and so on.

[0218] Alternatively, the terminal may also select a contiguous RB set that can transmit the largest number of PSFCHs (with a priority higher than a certain level, such as 2, 3, 4, 5, etc.).

[0219] It should be noted that, as described above, after determining an RB set, when looking for its continuous RB sets to be transmitted, it may be possible to consider only the RB sets remaining after executing the priority processing process. For example, the continuous RB sets of RB set2 can only be RBset3, or it may be all RB sets with PSFCH to be transmitted. For example, the continuous RB sets of RB set2 are not only RBset3, but may also be RB set1.

[0220] Example 2

[0221] In the process of executing the priority processing procedure, the terminal considers the selection of PSFCH according to the following criteria. Figure 5bAs shown, assuming that the PSFCH to be sent is located on RB set0, RB set2, and RB set3, since RB set0, RB set2, and RB set3 are non-continuous, the terminal can select the PSFCH on the most RB sets that can be sent continuously, that is, RB set2 and RB set3.

[0222] Alternatively, the terminal selects the RB set where the PSFCH with the highest priority is located, and if this RB set has a connected RBset, it is sent together, if not, it is sent separately. For example, if the PSFCH with the highest priority is located in RB set2, the PSFCHs on RB set2 and RB set3 are sent together; and if the PSFCH with the highest priority is located in RB set0, only the PSFCH on RB set0 is sent. At this time, if the PSFCH with the highest priority is located in different RB sets, then in this case, it is possible to consider selecting the RB set where the PSFCH with the largest number of priorities is located, and it is also possible to give priority to whether there is a connected RBset and / or the RB set with the second highest priority (or a priority higher than a certain level, such as 2, 3, 4, 5, etc.) and the largest number.

[0223] Alternatively, the terminal may select a contiguous RB set that can transmit the most PSFCHs (with a priority higher than a certain level, such as 2, 3, 4, 5, etc.) as much as possible.

[0224] It should be noted that when multiple RB sets are selected for transmission according to certain criteria, the number of PSFCHs on these RB sets may exceed the maximum number specified by the UE capability. There are two possibilities at this time. One is to discard according to priority. If the RB sets are not connected at this time, further selection is made according to the relevant behavior in Example 1. The second possibility is that if a certain RB set is determined for transmission first, the transmission of all PSFCHs on this RB set (or with a priority higher than a certain level, such as 2, 3, 4, 5, etc.) is prioritized, and then the transmission of all PSFCHs on the connected RB sets (or with a priority higher than a certain level, such as 2, 3, 4, 5, etc.) is determined.

[0225] like Figure 6 As shown, it is a structural diagram of a communication device 600 provided in an embodiment of the present application, and the device 600 includes: a determination module 610, used to determine a second number of target transmissions from a first set according to a first number; a transmission module 620, used to perform SL transmission based on the second number of the target transmissions; wherein the first set includes at least one first transmission, and the first number is related to the transmission restriction of the terminal.
