[0021] The following clearly and completely describes the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without any creative effort are within the scope of protection of the present application.

[0022] The terms "first," "second," etc. in the specification and claims of this application are intended to distinguish between similar objects and are not intended to describe a particular order or sequence. It is to be understood that the data so used may be interchanged where appropriate, such that the embodiments of this application may be performed in an order other than that shown or described herein. Note that "and / or" in the specification and claims indicates at least one of the objects connected, and the character " / " generally indicates that the related objects are in an "or" relationship.

[0023] For ease of understanding, first, some contents related to the embodiments of the present application are described as follows.

[0024] In an embodiment of the present application, a Downlink Control Information (DCI) format number for scheduling the uplink may be x-0, for example including 0-0 and 1-0.

[0025] Alternatively, the DCI format number for scheduling the downlink may be 1 to X, the DCI format number for scheduling the uplink may be 0 to X, and the DCI format number for scheduling the SL may be 3 to X.

[0026] In the embodiment of the present application, a sidelink user equipment may be a transmitting user equipment or a receiving user equipment, i.e., the same user equipment may receive or transmit on different time or frequency domains, respectively. Since the transmission of a sidelink data packet may be on a sidelink between user equipments, a control node (e.g., a base station) may not directly know whether the transmission of the sidelink data packet is successful or not, and the user equipment needs to send sidelink HARQ-ACK information (e.g., sidelink ACK / NACK) to the control node, which can further determine whether the transmission on the sidelink is successful or not. In a scheduled resource allocation mode (commonly referred to as mode-1), the user equipment may report SL HARQ information to the control node by a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH).

[0027] The SL HARQ information report supports being reported in a codebook format, in which an uplink resource for a SL HARQ information report may be associated with one or more Physical Sidelink Feedback Channel (PSFCH) resources, and the priority of the PSFCH is associated with the priority of other corresponding SL transmissions (Physical Sidelink Control Channel (PSCCH) and / or Physical Sidelink Shared Channel (PSSCH)). However, for some special situations, the receiving device has not done HARQ feedback or the transmitting device has not detected the PSFCH, and there is still SL HARQ information.

[0028] The method of determining the HARQ-ACK codebook includes two methods: a semi-static method (e.g., type 1 codebook) and a dynamic method (e.g., type 2 codebook). When the semi-static method is adopted, the HARQ-ACK codebook is a semi-static codebook, and its size, i.e., the number of bits included, is fixed. On the other hand, when the dynamic method is adopted, the HARQ-ACK codebook is a dynamic codebook, and its size, i.e., the number of bits included, can be dynamically changed.

[0029] Optionally, the terms sidelink, sublink, side link, edge link, direct communication link, sidelink and SL in this application may be substituted for each other.

[0030] Optionally, in this application, a UL DCI may be a DCI for scheduling an uplink resource, a DCI for activating an uplink resource, or a DCI for deactivating an uplink resource. A DL DCI may be a DCI for scheduling a downlink resource, a DCI for activating a downlink resource, or a DCI for deactivating a downlink resource. A SL DCI may be a DCI for scheduling a SL resource, a DCI for activating a SL resource, or a DCI for deactivating a SL resource.

[0031] Alternatively, the SL DCI may be at least one of DCI format 3-0 and DCI format 3-1, or a DCI format scrambled by the SL-RNTI or SL-CS-RNTI.

[0032] Alternatively, the UL DCI may be at least one of DCI format 0-0, DCI format 0-1, DCI format 0-2, or another DCI format for UL scheduling.

[0033] Optionally, in this application, at least one of uplink control information (UCI) related to Uu transmission, such as HARQ information, channel state information (CSI), scheduling request (SR) information, etc., may be referred to as Uu feedback information or Uu report information.

[0034] Optionally, in this application, at least one of SL feedback or control information related to SL transmission, such as SL HARQ information, SL CSI, etc., may be referred to as SL feedback information or SL report information.

[0035] It should be noted that, although the present application may use UL DCI format 0-1 as an example for illustration, the UL DCI applied to the present application may be another UL DCI format, for example, UL DCI format 0-0 or UL DCI format 0-2.

[0036] The present application will be described in detail below with reference to examples and drawings.

[0037] First embodiment 1 is a flow chart of an information indication method according to an embodiment of the present application, which is used in a terminal. As shown in FIG. 1, the method includes the following steps:

[0038] Step 101: Obtain control signaling.

[0039] In this embodiment, the control signaling may be UL DCI or higher layer signaling. It should be noted that the UL DCI may be sent by a network device, for example, a base station, to the terminal. The UL DCI may be received by the terminal from the base station. The higher layer signaling may be obtained in any one of the following manners: configured by the base station, pre-configured, defined by a protocol, indicated by another terminal, etc. For example, the higher layer signaling may be obtained in a pre-configured manner.

[0040] Step 102: Determine relevant information of the SL feedback information according to the control signaling.

[0041] Optionally, the control signaling is used to indicate related information of SL feedback information. The control signaling may include at least one of a first parameter field and a Downlink Assignment Index (DAI) field. The first parameter field is used to indicate related information of SL feedback information. The DAI field is used to indicate related information of SL feedback information or related information of Uu feedback information.

[0042] For example, in some cases, the signaling overhead can be reduced by reusing the DAI field in the UL DCI to indicate the relevant information of the SL feedback information. For example, at some times (e.g., when the uplink resource scheduled by this UL DCI collides with the resource of the SL feedback information), the DAI field in the UL DCI indicates the relevant information of the SL feedback information. However, at other times (e.g., when the uplink resource scheduled by this UL DCI collides with the resource of the Uu feedback information), the DAI field in the UL DCI indicates the count information of the relevant information of the Uu feedback information. This collision may be understood as the time domain and / or frequency domain at least partially overlapping or located within the same time domain range and / or located within the same frequency domain range. For example, located in the same slot.

[0043] The first parameter field represents an SL parameter domain, and may be called a (Sidelink Assignment Index, SAI) field, etc. Also, for example, in some cases, a parameter domain for SL (e.g., a first parameter field) is introduced in UL DCI or higher layer signaling, and by indicating related information of the SL feedback information by this parameter domain, the communication partner can easily know related information of the SL feedback information and can agree on the understanding of the communication partner's SL feedback information (e.g., an SL codebook).

[0044] Also for example, in some cases, the DAI field and the first parameter field can be used in combination to indicate related information of the SL feedback information, such as using the DAI field to indicate permission of the SL feedback information and using the first parameter field to indicate count information of the SL DCI.

[0045] In one embodiment, the higher layer signaling may include at least one of Radio Link Control (RRC) signaling, System Information Block (SIB), Medium Access Control (MAC) layer signaling, Radio Link Control (RLC) layer signaling, Packet Data Convergence Protocol (PDCP) layer signaling, and Service Data Adaptation Protocol (SDAP) layer signaling.

[0046] In the information indication method of the embodiment of the present application, the terminal can obtain control signaling, the control signaling includes at least one of a first parameter field and a DAI field, and the control signaling is used to indicate relevant information of the SL feedback information, so that the relevant information of the SL feedback information can help the terminal and a network device, such as a base station, to have a consistent understanding of the SL feedback information (such as an SL codebook), thereby enhancing the reliability of the SL feedback information.

[0047] Optionally, the related information of the SL feedback information may include at least one of the following:

[0048] SL feedback information permission (for example, whether or not the terminal is permitted to transmit SL feedback information on the PUSCH scheduled by the UL DCI).

[0049] Count information of SL DCI (which may be expressed as a Sidelink Assignment Index (SAI) for example). Here, the count information may include at least one of a counter Sidelink Assignment Index (cSAI) of the SL DCI and a total Sidelink Assignment Index (tSAI) of the SL DCI. The cSAI indicates the number of the SL DCI, and the tSAI indicates the total number of the SL DCI. In this way, the cSAI and the tSAI enable the terminal to easily determine whether the SL DCI has been lost, and further feed back desired SL feedback information to the base station.

[0050] Optionally, the related information of the above Uu feedback information is as follows: A) to B) It may include at least one.

[0051] a) Allow Uu feedback information

[0052] stomach) DL DCI count information (which may be expressed as, for example, a Downlink Assignment Index (DAI)) Here, the count information may include at least one of a DL DCI number downlink assignment index (cDAI) and a DL DCI total downlink assignment index (tDAI). The cDAI indicates the DL DCI number, and the tDAI indicates the total number of DL DCI.

[0053] In the embodiment of the present application, when the DAI field in the UL DCI is reused to indicate the relevant information of the SL feedback information, if the DAI field indicates the relevant information of the SL feedback information, the following a)~e) may include at least one of the following.

[0054] a) If the UL DCI includes a first DAI field (or includes a 1st DAI field, or is deemed to include a 1- or 2-bit DAI), the first DAI field (or includes a 1st DAI field, or is deemed to include a 1- or 2-bit DAI) indicates permission of SL feedback information.

[0055] For example, if this bit is 0, the SL feedback information can be transmitted on the PUSCH scheduled by this UL DCI. Or, if this bit is 1, the SL feedback information cannot be transmitted on the PUSCH scheduled by this UL DCI. On the other hand, if this bit is 1, the SL feedback information can be transmitted on the PUSCH scheduled by this UL DCI. Or, if this bit is 0, the SL feedback information cannot be transmitted on the PUSCH scheduled by this UL DCI.

[0056] Also, for example, if these 2 bits are 11 or the value corresponding to these 2 bits is 4, the SL feedback information can be transmitted on the PUSCH scheduled by this UL DCI, or cannot be transmitted on the other hand. Or, if these 2 bits are 11 or the value corresponding to these 2 bits is 4, the SL feedback information cannot be transmitted on the PUSCH scheduled by this UL DCI, or can be transmitted on the other hand.

[0057] b) If the UL DCI includes a first DAI field (or includes a 1st DAI field or is deemed to include a 1-bit DAI), the first DAI field (or includes a 1st DAI field or is deemed to include a 1-bit DAI) indicates the count information SAI of the SL DCI.

[0058] For example, this count information SAI may specifically be the cSAI or tSAI of the SL DCI.

[0059] c) If the UL DCI includes a first DAI field (or includes a 1st DAI field, or is deemed to include a 2-bit DAI), the first DAI field (or includes a 1st DAI field, or is deemed to include a 2-bit DAI) indicates the count information SAI of the SL DCI.

[0060] For example, this count information SAI may specifically be the cSAI or tSAI of the SL DCI.

[0061] Optionally, in some cases, the UL DCI includes only the 1st DAI field (or includes a 2-bit DAI, or includes a 2-bit SAI), such as when the uplink resource scheduled by this UL DCI conflicts with the resource of the SL feedback information, or when the UL DCI and / or higher layer configuration indicates that the DAI field in the UL DCI indicates related information of the SL feedback information.

[0062] d) When the UL DCI includes a first DAI field and a second DAI field (or is said to include a 4-bit DAI), the first DAI field (or the first 2-bit DAI) indicates a cSAI and the second DAI field (or the last 2-bit DAI) indicates a tSAI, or the first DAI field (or the first 2-bit DAI) indicates a tSAI and the second DAI field (or the last 2-bit DAI) indicates a cSAI.

[0063] e) If the UL DCI includes a first DAI field and a second DAI field (or is referred to as including a 4-bit DAI), the first DAI field (or the first 2-bit DAI) indicates a cSAI or a tSAI and the second DAI field is ignored, or the second DAI field (or the last 2-bit DAI) indicates a preset value, or the second DAI field (or the last 2-bit DAI) indicates a cSAI or a tSAI and the first DAI field is ignored, or the first DAI field (or the first 2-bit DAI) indicates a preset value. Optionally, the preset value may be any one of a value of all 1's, a value of all 0's, an invalid value, a redundant value, etc. For example, 2 bits are '11', or a value corresponding to 2 bits is 4.

[0064] Optionally, determining related information of the SL feedback information based on the DAI field in the UL DCI includes: determining permission for SL feedback information based on a first DAI field in the UL DCI; determining counting information of a SL DCI based on a first DAI field in the UL DCI; determining a cSAI and a tSAI based on a first DAI field and a second DAI field in an UL DCI (e.g., the first DAI field indicates a cSAI and the second DAI field indicates a tSAI, or the first DAI field indicates a tSAI and the second DAI field indicates a cSAI); determining a cSAI or tSAI based on a first DAI field or a second DAI field in a UL DCI (e.g., the first DAI field indicates a cSAI or tSAI, and the second DAI field is ignored, or the second DAI field indicates a pre-configured value, or the second DAI field indicates a cSAI or tSAI, and the first DAI field is ignored, or the first DAI field indicates a pre-configured value, and the pre-configured value is one of a value that is all 1's, a value that is all 0's, an invalid value, or a redundant value).

[0065] Alternatively, when a first parameter field (e.g., an SAI field) in the UL DCI indicates related information of the SL feedback information, when this first parameter field indicates related information of the SL feedback information, it may include at least one of the following:

[0066] 1) The UL DCI carries a 1-bit or 2-bit SL feedback information grant (which may be called SAI).

[0067] For example, if this 1 bit is 0, the SL feedback information can be transmitted on the PUSCH scheduled by this UL DCI. Or, if this 1 bit is 1, the SL feedback information cannot be transmitted on the PUSCH scheduled by this UL DCI. Or, if this 1 bit is 1, the SL feedback information can be transmitted on the PUSCH scheduled by this UL DCI. Or, if this 1 bit is 0, the SL feedback information cannot be transmitted on the PUSCH scheduled by this UL DCI.

[0068] Also, for example, if these 2 bits are 11 or the value corresponding to these 2 bits is 4, the SL feedback information can be transmitted on the PUSCH scheduled by this UL DCI, but cannot be transmitted conversely. Or, if these 2 bits are 11 or the value corresponding to these 2 bits is 4, the SL feedback information cannot be transmitted on the PUSCH scheduled by this UL DCI, or can be transmitted conversely.

[0069] 2) The UL DCI carries a 1-bit SAI to indicate permission for SL feedback information.

[0070] For example, if this bit SAI is 0, the SL feedback information can be transmitted on the PUSCH scheduled by this UL DCI; or if this bit SAI is 1, the SL feedback information cannot be transmitted on the PUSCH scheduled by this UL DCI; or if this bit SAI is 1, the SL feedback information can be transmitted on the PUSCH scheduled by this UL DCI; or if this bit SAI is 0, the SL feedback information cannot be transmitted on the PUSCH scheduled by this UL DCI.

[0071] 3) The UL DCI carries a 2-bit SAI, which is the number cSAI or the total number tSAI of SL DCIs. Specifically, for example, the number of the last SL DCI up to the current time or the immediately preceding time, or specifically, for example, the total number of SL DCIs up to the current time or the immediately preceding time.

[0072] 4) UL DCI carries a 2-bit cSAI and a 2-bit tSAI, which are the SL DCI number and the total number of SL DCIs, respectively, e.g., the number of the last SL DCI up to the current time or the immediately preceding time, or the total number of SL DCIs up to the current time or the immediately preceding time.

[0073] In one embodiment, the conventional DAI field in the UL DCI can be used to indicate the SAI, and in the case of a semi-static codebook, the DAI field can be used to indicate a 1-bit SAI, but in the case of a dynamic codebook, the DAI field can be used to indicate a 2-bit SAI.

[0074] In another embodiment, the conventional DAI field in the UL DCI can be used to indicate the SAI, and in the case of a semi-static codebook, the first DAI field may include a 1 or 2 bit SAI, and in the case of a dynamic codebook, the first DAI field may include a 2 bit SAI, and in the case of a dynamic codebook and two sub-codebooks, the second DAI field does not indicate the SAI.

[0075] In another embodiment, the UL DCI includes a DAI field and an SAI field, and the SAI field includes 1 bit if the semi-static codebook is used and at least one of the following conditions is met: SL CG type1 is configured, SL CG type2 is configured, SL CG type2 is activated, and monitoring SL DCI is configured. Preferably, the SAI field includes 1 bit if the semi-static codebook is used and at least one of the following conditions is met: SL CG (type1 and / or type2) is configured, and / or monitoring SL DCI is configured. However, the SAI field includes 2 bits if the dynamic codebook is used and at least one of the following conditions is met: SL CG type1 is configured, SL CG type2 is configured, SL CG type2 is activated, and monitoring SL DCI is configured. Preferably, when it is a dynamic codebook and SL CG (type 1 and / or type 2) is configured and / or monitoring SL DCI is configured, the SAI field includes 2 bits.

[0076] In another embodiment, the DAI is employed in some cases to indicate the SAI, and in other cases the UL DCI includes a dedicated SAI field. For example, in the case of a semi-static codebook, a first 1-bit DAI field can be used to indicate the SAI, and in the case of a dynamic codebook, the DCI further includes a 2-bit SAI in addition to the DAI.

[0077] It should be noted that, optionally, the SL feedback information can be transmitted on this PUSCH for the case where the SL feedback information satisfies the following first situation: Further optionally, the SL feedback information can be transmitted on this PUSCH even if the permission or SAI field of the SL feedback information indicates a value (e.g., 0, e.g., 11 or value 4) corresponding to not being able to be transmitted on the PUSCH scheduled by this UL DCI in the above interpretation.

[0078] Alternatively, the SL feedback information cannot be transmitted on this PUSCH when the SL feedback information satisfies the following first situation: Further alternatively, the SL feedback information can be transmitted on the PUSCH even if the grant or SAI field of the SL feedback information indicates a value (e.g., 1, 2, or 3) corresponding to being able to be transmitted on the PUSCH scheduled by this UL DCI in the above interpretation.

[0079] Here, the first case may include at least one of the following:

[0080] a) There is only a NACK in the SL feedback information.

[0081] For example, the SL feedback information has N1 bits and is an N1 bit NACK.

[0082] b) The SL feedback information is a NACK, and the NACK corresponds to the unicast or groupcast feedback mechanism option 2.

[0083] c) The SL feedback information is a NACK, and the NACK corresponds to the groupcast feedback mechanism option 1.

[0084] d) In the SL feedback information there is only an ACK.

[0085] e) The SL feedback information is SL HARQ information corresponding to the PSSCH and / or PSCCH that is abandoned or canceled by the user. For example, a user has multiple transmissions at the same time, and the user compares the SL HARQ information corresponding to the PSSCH and / or PSCCH that is abandoned or canceled by priority.

[0086] f) The SL feedback information is SL HARQ information corresponding to the PSFCH that is abandoned or canceled by the user. For example, a user has multiple transmissions at the same time, and the user compares the SL HARQ information corresponding to the PSFCH that is abandoned or canceled according to priority.

[0087] g) The SL feedback information is that the SL HARQ information corresponding to the SL CG is not actually used.

[0088] For example, none of the resources in one period of one SL CG is actually used for transmission, and the corresponding SL feedback information is an ACK.

[0089] h) The SL feedback information is SL HARQ information corresponding to a first transmission, where the first transmission may include at least one of a blind transmission, a blind retransmission, a transmission after turning off HARQ feedback, a broadcast transmission, a transmission that does not support HARQ feedback, a transmission in a resource pool where no PSFCH is configured, and the like.

[0090] i) The SL feedback information is SL HARQ information corresponding to a second transmission, where the second transmission may include a transmission via at least one of a groupcast feedback mechanism option 1, a groupcast feedback mechanism option 2, a unicast, etc., and the SL HARQ information is SL HARQ information corresponding to a case where at least one PSFCH has not been detected among the PSFCHs corresponding to this transmission.

[0091] j) The SL feedback information is SL HARQ information corresponding to the maximum number of transmissions or the maximum number of retransmissions.

[0092] Optionally, the maximum number of transmissions or maximum number of retransmissions that is satisfied is dynamic scheduling, for example the maximum number of transmissions or maximum number of retransmissions associated with the DCI.

[0093] II. Optionally, the maximum number of transmissions or maximum number of retransmissions to be met is a semi-static schedule, for example the maximum number of transmissions or maximum number of retransmissions associated with the SL CG.

[0094] III. Satisfying the maximum number of transmissions or the maximum number of retransmissions Nmax mentioned above includes two cases.

[0095] (1) A certain TB was actually transmitted Nmax times.

[0096] (2) Although the Nmax-th candidate resource is used to transmit this TB, the actual number of transmissions may be less than Nmax, i.e., the previous Nmax-1 candidate resources may only be partially used to transmit this TB.

[0097] For example, Nmax=2, there are three resources in one CG, and the user starts transmitting from the third resource, and Nmax is reached at this time even though only one transmission has been made.

[0098] k) The SL feedback information is or at least includes SL CSI (eg, includes SL CSI and SL HARQ information).

[0099] Abandon / cancel / do not transmit IUu feedback information and / or transmit SL feedback information and Uu report information.

[0100] The priority of the II or SL feedback information and the Uu report information are compared to determine which one to transmit.

[0101] The groupcast feedback mechanism option 1 (NACK-only feedback) is to feed back a NACK if data is received but cannot be decoded, and not to feed back in other cases. In such a case, if the receiver does not receive a NACK, it is considered that all receivers have successfully received and decoded the data. However, one of the drawbacks of this mechanism is that the sender may confuse the two cases of successful data reception and unsuccessful SCI reception, i.e., the receiver does not successfully receive the SCI and data, but the sender believes that the receiver has successfully received it. This method is applied to connectionless groupcast scenarios.

[0102] The above groupcast feedback mechanism option 2 (ACK / NACK feedback) feeds back a NACK if data is received but cannot be decoded, or an SCI is received but no data is received, and feeds back an ACK if data is received and correctly decoded.

[0103] In an embodiment of the present application, the above control signaling does not further include type indication information, and the type indication information is used to indicate whether the control signaling indicates related information of SL feedback information or related information of Uu feedback information.

[0104] For example, type indication information in higher layer signaling indicates that the relevant information of SL feedback information is indicated by the UL DCI, and type indication information in a further UL DCI indicates that the relevant information of SL feedback information is indicated by the DAI field in this UL DCI.

[0105] For example, when the type indication information in the UL DCI or higher layer signaling is 1 bit and the possible values ​​are 0 or 1, 0 may indicate that the DAI field in the UL DCI indicates related information of SL feedback information, and 1 may indicate that the DAI field in the UL DCI indicates related information of Uu feedback information (e.g., counting information), or 0 may indicate that the DAI field in the UL DCI indicates related information of Uu feedback information (e.g., counting information), and 1 may indicate that the DAI field in the UL DCI indicates related information of SL feedback information.

[0106] Also, for example, if the type indication information exists in the UL DCI or higher layer signaling, the DAI field in the UL DCI indicates relevant information of the SL feedback information, or if the type indication information does not exist in the UL DCI or higher layer signaling, the DAI field in the UL DCI indicates relevant information of the Uu feedback information (e.g., counting information). Or, if the type indication information does not exist in the UL DCI or higher layer signaling, the DAI field in the UL DCI indicates relevant information of the SL feedback information, or if the type indication information exists in the UL DCI or higher layer signaling, the DAI field in the UL DCI indicates relevant information of the Uu feedback information (e.g., counting information).

[0107] In the examples of the present application, (1) At least one SL semi-static scheduling configuration that does not require a grant is configured in the terminal, for example, at least one SL configured grant type 1 is configured; (2) At least one SL semi-static scheduling configuration that requires a grant is configured in the terminal, for example, at least one SL configured grant type 2 is configured; (3) the terminal has at least one SL semi-static scheduling configuration that requires a grant activated, for example, at least one SL configured grant type 2 activated; (4) The terminal needs to monitor or receive SL DCI (e.g., DCI format 3_0); and (5) When the type of the SL feedback information of the terminal is semi-static or type 1, for example, pdsch-HARQ-ACK-Codebook=semi-static, the above control signaling (e.g., a first parameter field and / or a DAI field) can indicate permission of count information SAI or SL feedback information of the SL DCI of a first pre-configured number of bits (e.g., 1 bit).

[0108] For example, the terminal is configured with SL CG (type 1 and / or type 2) and / or configured with monitoring SL DCI, and the type of SL feedback information is semi-static.

[0109] Selectively, (6) At least one SL semi-static scheduling configuration that does not require a grant is configured in the terminal, for example, at least one SL configured grant type 1 is configured; (7) The terminal is configured with at least one SL semi-static scheduling configuration that requires a grant, for example, at least one SL configured grant type 2; (8) The terminal has at least one SL semi-static scheduling configuration that requires a grant activated, for example, at least one SL configured grant type 2 activated; (9) The terminal needs to monitor or receive SL DCI (e.g., DCI format 3_0); and (10) When the type of the SL feedback information of the terminal is dynamic or type 2, for example, pdsch-HARQ-ACK-Codebook=dynamic, the above control signaling (e.g., the first parameter field and / or the DAI field) can indicate SL DCI count information SAI of a second pre-configured number of bits (e.g., 2 or 4 bits).

[0110] For example, the terminal is configured with SL CG (type 1 and / or type 2) and / or configured with monitoring SL DCI, and the type of SL feedback information is dynamic.

[0111] It should be noted that the above conditions (1) to (10) are conditions applied to the terminal itself, and if these conditions are not met, the above control signaling may carry related information of 0 bit SL feedback information.

[0112] Alternatively, if the UL DCI does not carry related information of the SL feedback information, the uplink resource scheduled by the UL DCI may be used for transmitting the SL feedback information when it collides with the resource of the SL feedback information, for example, the uplink resource is silently used for transmitting the SL feedback information. This collision may be interpreted as 1) the time domain and / or the frequency domain at least partially overlapping, or 2) being located within the same time domain range and / or being located within the same frequency domain range.

[0113] Optionally, in this embodiment, for the value of SAI in the related information of the SL feedback information, a) the SL DCI number, e.g., cSAI, indicated by the UL DCI is the number indicated by the immediately preceding SL DCI; b) the total number of SL DCIs, e.g., tSAI, indicated by the UL DCI is the total number indicated by the immediately preceding SL DCI; c) The SL DCI number, e.g., the cSAI, indicated by the UL DCI is a number indicated by the SL DCI; d) the total number of SL DCIs indicated by the UL DCI, for example, tSAI, is the total number indicated by the SL DCI.

[0114] Alternatively, in this embodiment, if the codebook type configured or preconfigured by the control node is a semi-static codebook or a type 1 codebook (e.g., pdsch-HARQ-ACK-Codebook=semi-static), the UL DCI may include a 1-bit SL feedback information permission and / or a 1-bit SAI.

[0115] After the terminal determines the SL feedback information based on the above method, the terminal can further selectively transmit the SL feedback information. The SL feedback information is transmitted to a control node, which may be a base station, an Integrated Access Backhaul (IAB) node, or other equipment on the SL, such as SL user equipment, a road site unit (RSU), etc.

[0116] 2 is a flow chart of an information indication method according to an embodiment of the present application, which is used in a network device. As shown in FIG. 2, the method includes the following steps:

[0117] Step 201: Send control signaling to a terminal.

[0118] In this embodiment, the control signaling is UL DCI or higher layer signaling. The control signaling includes at least one of a first parameter field and a DAI field, and the control signaling is used to indicate related information of SL feedback information. The first parameter field is used to indicate related information of SL feedback information, and the DAI field is used to indicate related information of SL feedback information or related information of Uu feedback information.

[0119] The information indication method in this embodiment can enhance the reliability of the SL feedback information by sending control signaling to the terminal to indicate related information of the SL feedback information, and by using this related information of the SL feedback information to help the terminal and a network device, e.g., a base station, to align their understanding of the SL feedback information (e.g., an SL codebook), thereby.

[0120] Optionally, the higher layer signaling may include at least one of RRC signaling, SIB, MAC layer signaling, RLC layer signaling, PDCP layer signaling, and SDAP layer signaling.

[0121] Optionally, the relevant information of the SL feedback information is SL feedback information permission, Count information of SL downlink control information SL DCI, the count information including at least one of a number sidelink allocation index cSAI of the SL DCI and a total number sidelink allocation index tSAI of the SL DCI.

[0122] Alternatively, if the DAI field indicates related information of the SL feedback information, If the UL DCI includes a first DAI field, the first DAI field indicates permission for SL feedback information; If the UL DCI includes a first DAI field, the first DAI field indicates count information of a SL DCI; When the UL DCI includes a first DAI field and a second DAI field, the first DAI field indicates a cSAI and the second DAI field indicates a tSAI, or the first DAI field indicates a tSAI and the second DAI field indicates a cSAI; When the UL DCI includes a first DAI field and a second DAI field, the first DAI field indicates a cSAI or a tSAI, and the second DAI field is ignored, or the second DAI field indicates a preset value, or the second DAI field indicates a cSAI or a tSAI, and the first DAI field is ignored, or the first DAI field indicates a preset value, and the preset value is one of a value that is all 1's, a value that is all 0's, an invalid value, and a redundant value.

[0123] Optionally, the control signaling may further include type indication information, where the type indication information is used to indicate the indication of related information of the SL feedback information by the control signaling, or the type indication information is used to indicate the indication of related information of the Uu feedback information by the control signaling.

[0124] Selectively, The terminal is configured with at least one SL semi-static scheduling configuration that does not require permission; and The terminal is configured with at least one SL semi-static scheduling configuration that requires authorization; and The terminal has at least one SL semi-static scheduling configuration activated that requires authorization; and The terminal needs to monitor or receive SL DCI; and If the type of the SL feedback information of the terminal satisfies at least one of the conditions of being semi-static, the control signaling (e.g., a first parameter field and / or a DAI field) indicates permission of SL feedback information or count information of a first preset number of bits of SL DCI.

[0125] Selectively, The terminal is configured with at least one SL semi-static scheduling configuration that does not require permission; and The terminal is configured with at least one SL semi-static scheduling configuration that requires authorization; and The terminal has at least one SL semi-static scheduling configuration activated that requires authorization; and The terminal needs to monitor or receive SL DCI; and If the type of the SL feedback information of the terminal satisfies at least one of the conditions of being dynamic, the control signaling (e.g., a first parameter field and / or a DAI field) indicates count information of a second preset number of bits of SL DCI.

[0126] The information indication method according to the embodiment of the present application is a network-side method corresponding to the embodiment of the method shown in Figure 1. Here, the specific interpretation of the content can be referred to the description of the above embodiment, and the same technical effect can be obtained, so no further description is given here.

[0127] Second embodiment At present, when implementing SL feedback, the time offset value of the time domain resource for determining the SL feedback information generally includes a dynamic time offset value and a semi-static time offset value. And these two kinds of time offset values ​​are generally respectively configured by different signaling, or pre-configured, or indicated, or defined by a protocol, etc. For one time domain resource of SL feedback information (such as PUCCH or PUSCH), the bit number and / or content of the SL feedback information are related to the time offset value related to this time domain resource. If the dynamic time offset value is different from the semi-static time offset value, the SL feedback information related only to the dynamic time offset value, the SL feedback information related only to the semi-static time offset value, and the SL feedback information related only to the dynamic time offset value and the semi-static time offset value may be different in terms of bit number and / or content, that is, the size of the bit number of the SL feedback information may change over time, thereby increasing the complexity of the blind detection of the base station, and the base station and the user cannot maintain a consistent understanding of the bit number of the SL feedback information, thereby causing a decrease in reliability. In order to solve the problem that the change in the size of the bit number of the SL feedback information may be inconsistent, the following method is proposed in this application.

[0128] 3 is a flow chart of an information determining method according to an embodiment of the present application, which is used in a terminal. As shown in FIG. 3, the method includes the following steps:

[0129] Step 301: Obtain a dynamic time offset value and a semi-static time offset value for determining a time domain resource where SL feedback information is located.

[0130] In this embodiment, time offset information for determining the time domain resource in which the SL feedback information is located, such as time offset K1 information, includes a dynamic time offset value (dynamic time offset K1) and / or a semi-static time offset value (semi-static time offset K1), and may be defined by a protocol / configured by a control node / pre-configured / instructed by another terminal.

[0131] For a dynamic time offset K1 and / or a semi-static time offset K1, For example, the dynamic time offset includes sl-FeedbackToUL-ACK-DG and / or sl-FeedbackToUL-ACK, where sl-FeedbackToUL-ACK-DG and / or sl-FeedbackToUL-ACK are parameter names for the time interval between the SL feedback (e.g., PSFCH) that is dynamically scheduled or activated by the SL and the resource for the SL feedback information (e.g., PUCCH or PUSCH).

[0132] II. For example, the semi-static time offset includes sl-ACKToUL-ACK and / or sl-FeedbackToUL-ACK-CG, where sl-ACKToUL-ACK and / or sl-FeedbackToUL-ACK-CG are parameter names for the time interval between the SL feedback (e.g., PSFCH) semi-statically scheduled by the SL and the resource of the SL feedback information (e.g., PUCCH or PUSCH).

[0133] A dynamic time offset means that after obtaining a dynamic time offset (which may be one or more time offsets defined by a protocol / configured by a control node / pre-configured / indicated by another terminal), a certain one or more of the dynamic time offsets may then be indicated by a first control signaling (e.g., SL DCI or SCI or MAC CE) (but this is not necessarily required).

[0134] For example, a possible time offset indicated by the SL DCI for scheduling SL resources configured by the base station is a dynamic time offset, such as sl-FeedbackToUL-ACK-DG.

[0135] Also, for example, the time offset indicated in a DCI for activating SL CG type 2 (sidelink configured grant type 2) is the time offset of the SL CG type 2 activated by this DCI, and for example, the DCI indicates that the base station configures a certain value or a certain value index of sl-FeedbackToUL-ACK-DG.

[0136] The semi-static time offset is a time offset corresponding to semi-static resource configuration. The so-called semi-static resource may be a SL CG (sidelink configured grant) configured by the base station, or it may be a semi-static resource on another SL, for example a semi-static resource that one or some SL UEs recommend or schedule or notify or indicate to one or some other SL UEs, or a semi-static SL resource, for example a pre-configured semi-static SL resource.

[0137] For example, the time offset in the SL CG configuration is sl-FeedbackToUL-ACK-CG.

[0138] Preferably, the sidelink configured grant type 1 (SL CG type 1) configuration includes a time offset of SL CG type 2, e.g. sl-FeedbackToUL-ACK-CG.

[0139] Optionally, a sidelink configured grant type 2 (SL CG type 2) configuration includes a time offset for SL CG type 2, e.g. sl-FeedbackToUL-ACK-CG.

[0140] In one embodiment, a control node can configure one or more CGs (configured grants), where each CG has its own time offset. For example, a control node can configure one or more CG type1s (CGs that do not require grants), where each CG type1 has its own time offset. For example, a control node can configure one or more CG type2s (CGs that require grants), where each DCI that activates a CG type2 has a time offset that includes at least one CG type2.

[0141] Step 302: determining one of: the semi-static time offset value includes the dynamic time offset value; or the dynamic time offset value includes the semi-static time offset value.

[0142] Whereas the semi-static time offset value includes the dynamic time offset value, the dynamic time offset value may be referred to as belonging to the semi-static time offset value, and the range of the dynamic time offset value may be understood to be within the range of the semi-static time offset value. For example, if three semi-static time offset values ​​are arranged, each of which is 1, 2, and 3, regardless of the number of dynamic time offset values, each of which should be a certain or some value in {1, 2, 3}. For example, there are four dynamic time offset values, each of which is 2, or there are two dynamic time offset values, each of which is 1, or there are three dynamic time offset values, each of which is 1, 2, and 3.

[0143] Whereas the dynamic time offset value includes a semi-static time offset value, the semi-static time offset value may be referred to as belonging to the dynamic time offset value, and the range of values ​​of the semi-static time offset value may be understood to be within the range of values ​​of the dynamic time offset value. For example, if three dynamic time offset values ​​are arranged, each of which is 1, 2, and 3, regardless of the number of semi-static time offset values, each of which should be a certain or some value in {1, 2, 3}. For example, there are four semi-static time offset values, each of which is 1, or there are two semi-static time offset values, each of which is 2, or there are three semi-static time offset values, each of which is 1, 2, and 3. Optionally, when the dynamic time offset includes multiple values, the semi-static time offset belongs to the dynamic time offset.

[0144] For example, if sl-FeedbackToUL-ACK-DG contains multiple values, then sl-FeedbackToUL-ACK-CG belongs to sl-FeedbackToUL-ACK-DG. If sl-FeedbackToUL-ACK-DG={1, 2, 3} and there are two SL CG type1s, SL CG type1#1 and SL CG type1#2, respectively, then the semi-static sl-FeedbackToUL-ACK-CGs corresponding to these two SL CG type1s should be some values ​​in {1, 2, 3}.

[0145] For example, if sl-FeedbackToUL-ACK-DG contains one value, then sl-FeedbackToUL-ACK-CG is equal to sl-FeedbackToUL-ACK-DG. If sl-FeedbackToUL-ACK-DG={1} places two SL CG type1, which are SL CG type1#1 and SL CG type1#2 respectively, then the semi-static sl-FeedbackToUL-ACK-CG corresponding to these two SL CG type1 should be 1.

[0146] Alternatively, if only the preset condition 1 is met, the semi-static time offset belongs to the dynamic time offset; otherwise (for example, there is no dynamic scheduling, or the SL CG is not configured, or the SL CG type1 is not configured, or the type of the SL feedback information is the dynamic codebook or the type2 codebook), there is no need to make the semi-static time offset belong to the dynamic time offset, so the so-called preset condition 1 is: a) the terminal needs to monitor or receive SL DCI (e.g. DCI format 3_0); and b) the terminal has at least one SL semi-static scheduling configuration configured that does not require a grant (e.g., at least one SL configured grant type 1 configured); c) the terminal is configured with at least one SL semi-static scheduling configuration that requires a grant (e.g., at least one SL configured grant type 2 is configured); and d) the terminal has at least one SL semi-static scheduling configuration that requires a grant activated (e.g., at least one SL configured grant type 2 activated); and e) The type of the SL feedback information of the terminal is semi-static or type 1.

[0147] For example, an SL CG (type 1 and / or type 2) is configured in the terminal, and / or a monitoring SL DCI is configured, and the type of the SL feedback information is semi-static, and the semi-static time offset at this time belongs to the dynamic time offset.

[0148] For example, when SL CG type 1 is configured in a terminal, and SL CG type 2 is configured in the terminal, and / or the terminal needs to monitor or receive DCI format 3_0, the terminal is provided with a set of time offsets K_1, and the set of K_1 includes K_1 corresponding to a semi-static time offset and K_1 corresponding to a dynamic time offset, at this time, the semi-static time offset belongs to the dynamic time offset, or the value corresponding to the dynamic time offset should include a value corresponding to the semi-static time offset.

[0149] For example, when the type of SL feedback information is dynamic codebook or type2 codebook, the semi-static time offset does not need to meet the requirement of dynamic time offset, that is, the semi-static time offset and the dynamic time offset may be the same or different.

[0150] The information determination method in the embodiment of the present application makes it possible to reduce the complexity of blind detection of the base station and improve reliability by making the semi-static time offset value for determining the time domain resource in which the SL feedback information is located belong to the dynamic time offset value, thereby maintaining the magnitude of the SL feedback information (especially when the SL feedback information is semi-static) at a constant value or within a relatively stable range.

[0151] 4 is a flow chart of an information configuration method according to an embodiment of the present application, which is used in a network device. As shown in FIG. 4, the method includes the following steps:

[0152] Step 401: Transmit configuration information to a terminal.

[0153] Here, the configuration information indicates a dynamic time offset value and a semi-static time offset value for determining a time domain resource in which the SL feedback information is located, and the semi-static time offset value includes the dynamic time offset value, or the dynamic time offset value includes the semi-static time offset value. For an explanation of the dynamic time offset value and the semi-static time offset value, please refer to the description of the embodiment shown in Figure 3 above, and no further description will be given here.

[0154] The configuration information may include first configuration information and second configuration information, where the first configuration information is used to indicate a dynamic time offset value and the second configuration information is used to indicate a semi-static time offset value. Furthermore, the first configuration information and the second configuration information may or may not be transmitted simultaneously, for example, the first configuration information is transmitted before the second configuration information, or the second configuration information is transmitted before the first configuration information.

[0155] Selectively, a) the terminal needs to monitor or receive SL DCI (e.g. DCI format 3_0); and b) the terminal has at least one SL semi-static scheduling configuration configured that does not require a grant (e.g., at least one SL configured grant type 1 configured); c) the terminal is configured with at least one SL semi-static scheduling configuration that requires a grant (e.g., at least one SL configured grant type 2 is configured); and d) the terminal has at least one SL semi-static scheduling configuration that requires a grant activated (e.g., at least one SL configured grant type 2 activated); and e) If at least one of the preset conditions is satisfied, the type of the SL feedback information of the terminal is semi-static or type 1 (but, for example, if the type of the SL feedback information is dynamic codebook or type 2 codebook, the semi-static time offset does not need to meet the requirement belonging to the dynamic time offset), the dynamic time offset value includes the semi-static time offset value, or the semi-static time offset value includes the dynamic time offset value.

[0156] The information determination method according to the embodiment of the present application is a network-side method corresponding to the embodiment of the method shown in FIG. 3 above, where the specific interpretation of the content can be referred to the description of the above embodiment, and the same technical effects can be obtained, and no further description will be given here.

[0157] Third embodiment Currently, when a time domain location corresponding to a time offset value for determining a time domain resource where SL feedback information is located, i.e., a time domain location where a resource related to a resource transmitting SL feedback information is located, belongs to multiple resource pools, there is currently no corresponding method for specifying how to determine the number of bits and / or content of the corresponding SL feedback information at this time, thereby ensuring that the terminal and the network device understand the SL feedback information in a consistent manner. Based on this, the following method is proposed in this application.

[0158] 5 is a flow chart of an information determining method according to an embodiment of the present application, the method being used in a communication device, such as a terminal or a network device. As shown in FIG. 5, the method includes the following steps:

[0159] Step 501: If a time domain position where an associated resource corresponding to a first time offset value is located belongs to P resource pools, determine the number of bits of SL feedback information corresponding to the time domain position according to a weighted sum of the time domain periods of the first resource.

[0160] In this embodiment, the time domain period may be interpreted as a time domain density, and the time domain period is N slots, i.e., there is an associated resource for every N slots. The P is a positive integer greater than 1, and the first time offset value is a time offset value for determining a time domain resource where the SL feedback information is located. The associated resource is a resource related to a resource that transmits the SL feedback information. The first resource is a resource corresponding to a type of the associated resource in the P resource pools.

[0161] By determining the number of bits of SL feedback information in the above manner, when multiple resource pools exist, it is possible to help users and base stations to have a consistent understanding of the SL feedback information, and to enhance reliability by avoiding the leakage of some SL feedback information.

[0162] In this embodiment, for a certain terminal, time offset information for determining the time domain resource where the SL feedback information is located can be defined by a protocol, configured by a control node, configured in advance, or indicated by another terminal. Based on the time offset information, the relevant resource related to the SL feedback information (or the relevant resource related to the resource where the SL feedback information is located) can be determined.

[0163] Optionally, the associated resources include time domain and / or frequency domain resources.

[0164] Alternatively, the type of the associated resource may be a PSFCH, for example determining an associated PSFCH reception occasion.

[0165] Optionally, the P resource pools are further resource pools on the same or different SL BWPs.

[0166] Alternatively, the P resource pools are resource pools on a SL BWP to be further activated or a SL BWP to be configured or a resource pool on a SL BWP to be pre-configured.

[0167] Optionally, the P resource pools are further SL resource pools on the same carrier or different carriers.

[0168] For example, adding a time domain resource corresponding to the time offset to the reference point is the time domain resource for transmitting the SL feedback information, so by calculating backwards, it is obtained that the resource where the SL feedback information is located minus the time domain resource corresponding to the time offset is related to the SL feedback information.

[0169] Alternatively, if a time domain location (which may refer to a slot or a symbol) of a related resource corresponding to a time offset belongs to P resource pools, denoted as {pool_0, pool_1, pool_2, ..., pool_p, ..., pool_(P-1)}, then the time domain location corresponds to SL feedback information of Tbits, where: JPEG0007618860000001.jpg17165N p is the time domain period or time domain density of the resources corresponding to the relevant resource type in the resource pool pool_p, i.e., T is the weighted sum of the relevant resource periods or time domain densities in the P resource pools, and α p is the weight of the resource pool pool_p, and preferably, α p =1.

[0170] For example, if the type of the associated resource is PSFCH, T is the sum of the time domain periodicity or the time domain density of the PSFCH resources of each resource pool among the P resource pools.

[0171] Furthermore, the P resource pools may be resource pools of resources corresponding to the type including related resources. For example, when the type of related resources is PSFCH, the P resource pools include the slot where the PSFCH is located, and the resource pool itself is a resource pool including the PSFCH, but this slot may or may not include the PSFCH. Also, for example, when a certain related resource PSFCH is located in slot1, the P resource pools are resource pools including this slot1 and including the PSFCH, but some resource pools may have the PSFCH on slot1, and some may have the PSFCH in a slot other than slot1.

[0172] Furthermore, the P resource pools may be resource pools including resources corresponding to the type of related resource included and resources corresponding to the type of the related resource at the time domain position where the related resource is located. For example, when the type of the related resource is PSFCH, the P resource pools are resource pools including the slot where the PSFCH is located and including the PSFCH at this slot. For example, when a certain related resource PSFCH is located at slot1, the P resource pools are resource pools including this slot1 and including the PSFCH at slot1.

[0173] Alternatively, among the P resource pools, there are some resource pools that include a time domain location of the relevant resource but do not include a time domain resource corresponding to the type of the relevant resource (for example, if an associated resource PSFCH is located in slot1, P resource pools include this slot1, and some of the P resource pools have no PSFCH resource), or among the P resource pools, there are some resource pools that include a resource corresponding to the associated resource type but do not have such a resource on the time domain location of the associated resource (for example, if an associated resource PSFCH is located in slot1, P resource pools include this slot1, but some of the P resource pools have a resource PSFCH but no PSFCH resource on slot1), then when calculating T (i.e., the number of bits of the SL feedback information), N corresponding to this or these resource pools may be used. p teeth, 1) 0 and 2) A preset value (e.g., N corresponding to another resource pool that contains this type of time domain resource) p The maximum value max{N p}, or the minimum value min{N p}, or the average value).

[0174] The following describes the application in detail with reference to specific examples.

[0175] Example 1: In the UL DCI, a SL parameter domain is introduced to indicate the SAI.

[0176] Assume that the SAI is carried in the UL DCI.

[0177] The UL DCI includes the SAI. - SAI is 0 or 1 or contains 2 bits; Alternatively, if it is a semi-static codebook, the SAI comprises 1 bit; alternatively, if it is a dynamic codebook, the SAI comprises 2 bits.

[0178] As another example, the UL DCI includes the SAI, - SAI-0, 1 or 2 bits: Optionally, the codebook is semi-static and the user - SL CG type1 is installed, - SL CG type2 is installed, - A monitoring SL DCI is in place. SAI contains 1 bit.

[0179] Optionally, the codebook is dynamic and the user - SL CG type1 is installed, - SL CG type2 is installed, - A monitoring SL DCI is in place. SAI contains 2 bits.

[0180] Alternatively, if the above conditions are not met, the SAI may be 0 bit.

[0181] As another example, the UL DCI includes a DAI and an SAI, - First DAI field - if it is a semi-static codebook, it contains 1 bit, - If it is a dynamic codebook, it contains 2 bits.

[0182] - second DAI field - 0 or 2 bits, i.e. the second DAI field may be absent and contain 0 bits or the second DAI field contains 2 bits; - if it is a dynamic codebook and there are two sub-codebooks, it contains 2 bits; - Otherwise, it is 0 bit.

[0183] - SAI-0, 1 or 2 bits, i.e. the SAI field may be absent, contain 0 bits or contain 1 bit or 2 bits; Optionally, the codebook is semi-static and the user - SL CG type1 is installed, - SL CG type2 is installed, - A monitoring SL DCI, e.g. DCI format 3_0, is configured, SAI contains 1 bit.

[0184] Optionally, the codebook is dynamic and the user - SL CG type1 is installed, - SL CG type2 is installed, - A monitoring SL DCI, e.g. DCI format 3_0, is configured, SAI contains 2 bits.

[0185] Alternatively, if the above conditions are not met, the SAI is 0 bit.

[0186] The UL DCI in this embodiment may be DCI format 0-1.

[0187] Example 2: A conventional field in the UL DCI (eg, the DAI field) is used to indicate the SAI and reuse some fields.

[0188] Assume that the UL DCI can indicate the permission of SL feedback information by the first DAI field. The UL DCI is the first DAI field contains 1 or 2 bits, i.e. the first DAI field contains 1 bit or the first DAI field contains 2 bits; - In the case of a semi-static codebook, it includes 1 bit, optionally indicating whether the PUSCH can be used for SL feedback information transmission when the PUSCH overlaps with the PUCCH of SL feedback information, indicating whether the PUSCH can be used for PUCCH of Uu report information transmission when the PUSCH overlaps with the PUCCH of Uu report information, If it is a dynamic codebook, it contains 2 bits.

[0189] - the second DAI field - contains 0 or 2 bits, i.e. the second DAI field may be absent, contains 0 bits, or the second DAI field contains 2 bits; -If it is a dynamic codebook and there are two sub-codebooks, it contains 2 bits; - Otherwise, contains 0 bit.

[0190] Alternatively, the DCI may be SAI-0, 2 bits; If it is a dynamic codebook, it contains 2 bits and is optionally used to indicate the SAI; - Otherwise, contains 0 bit.

[0191] As another example, The SAI is indicated by the DAI field in the UL DCI. The UL DCI is - the first DAI field contains 1 or 2 bits, i.e. the first DAI field contains 1 bit or the first DAI field contains 2 bits; - In the case of a semi-static codebook, it includes 1 bit, optionally indicating whether the PUSCH can be used for SL report information transmission when the PUSCH overlaps with the PUCCH of SL report information, indicating whether the PUSCH can be used for Uu report information transmission when the PUSCH overlaps with the PUCCH of Uu report information, - if it is a dynamic codebook, it includes 2 bits, optionally indicating an SAI, e.g., a number or total number of SL DCIs, when the PUSCH overlaps with a PUCCH of SL report information, and indicating a DAI, e.g., a number or total number of DL DCIs, when the PUSCH overlaps with a PUCCH of Uu report information; - a first DAI field - containing 0 or 2 bits, i.e. the first DAI field may be absent, containing 0 bits, or the first DAI field contains 2 bits; - if it is a dynamic codebook and there are two sub-codebooks, it contains 2 bits, where optionally, if the PUSCH overlaps with the PUCCH of the SL report information, the user ignores this field, or this field is set as 00 or a redundant value; - Otherwise, contains 0 bit.

[0192] The UL DCI in this example may be DCI format 0-1.

[0193] Example 3: A type 1 codebook (semi-static codebook) is determined based on the SAI in DCI.

[0194] When a user transmits SL feedback information on one PUSCH not scheduled by DCI (e.g., a PUSCH on a UL configured grant) or a PUSCH scheduled by DCI format 0_0, for example, when the user wants to multiplex and transmit SL HARQ-ACK information on this PUSCH, Alternatively, if the user has no SL feedback information corresponding to the SL DCI (e.g., has not received a SL DCI associated with a PSFCH) and no SL feedback information corresponding to the SL CG (e.g., has no SL feedback information corresponding to a PSFCH associated with a SL CG), the user does not multiplex the SL HARQ-ACK information on the PUSCH; or optionally, if no PSSCH is transmitted in the PSSCH occasion set corresponding to the resource of the SL feedback information (e.g., not scheduled by SL DCI or not transmitted on SL CG resources in the occasion set), the user does not multiplex SL HARQ-ACK information on the PUSCH; - Otherwise, optionally the user generates SL feedback information and optionally transmits this SL feedback information on the PUSCH.

[0195] For an SL DCI that is later than the above-mentioned UL DCI (DCI format 0_0 or a DCI format 0_1), for example, an SL DCI whose starting point is later than the UL DCI, the bit that corresponds to the SL feedback information is set as NACK. The user does not want to receive DCI for switching downlink BWP or uplink BWP in the first N2' symbols of the PUSCH, where N2' is a processing delay. For example, when SL feedback information is multiplexed on the PUSCH, the user does not want to receive DCI for switching downlink BWP or uplink BWP in the first N2' symbols of the PUSCH, where N2' is a processing delay. Optionally, N2' is related to at least one of the number of PSFCHs received by the user, the PSFCH capabilities received by the user, the number of bits included in the SL feedback information, the SL SCS (subcarrier spacing), and the PUSCH SCS.

[0196] When a user transmits SL feedback information on one PUSCH scheduled by DCI format 0_1 ​​and, for example, wants to multiplex and transmit SL HARQ-ACK information on this PUSCH, SAI V UL T-SAI If SAI=1, the user generates, multiplexes, and transmits SL feedback information. If SAI=0 in DCI format 0_1, the user cannot multiplex and transmit on PUSCH. Or, if the SL feedback information only includes feedback information corresponding to one SL DCI, and the value of the counter SAI field in the SL DCI is 1, or only includes feedback information corresponding to one SL CG, the SL feedback information can be multiplexed on PUSCH.

[0197] In the above example, as one implementation, SAI in DCI format 0_1 ​​is '0', otherwise, V UL T-SAI =1.

[0198] In the above example, one possible implementation is V UL T-SAI V SL C-SAI can be replaced by.

[0199] Example 4: A type 2 codebook (dynamic codebook) is determined based on the SAI in the DCI.

[0200] When a user transmits SL feedback information on one PUSCH not scheduled by DCI (e.g., a PUSCH on a UL configured grant) or a PUSCH scheduled by DCI format 0_0, for example, when the user wants to multiplex and transmit SL HARQ-ACK information on this PUSCH, Alternatively, if the user does not have SL feedback information corresponding to the SL DCI (e.g., does not receive a SL DCI associated with a PSFCH) and does not have SL feedback information corresponding to the SL CG (e.g., does not have SL feedback information corresponding to a PSFCH associated with a SL CG), the user does not multiplex the SL HARQ-ACK information on the PUSCH; Otherwise, optionally, SL HARQ-ACK information is multiplexed and transmitted on the PUSCH.

[0201] When a user transmits SL feedback information on one PUSCH scheduled by DCI format 0_1, for example, when the user wants to multiplex and transmit SL HARQ-ACK information on this PUSCH, the user generates SL feedback information, and in this generation process, - Optionally, SL DCI count information V temp V temp =V UL T-SAI where V UL T-SAI is a value corresponding to SAI in DCI format 0_1 ​​(the value corresponding to SAI can be determined based on Table 1 below) SAI value V of DCI format 0_1 UL T-SAI If =4 and the user has no SL feedback information corresponding to the SL DCI (e.g., has not received an SL DCI associated with the PSFCH) and has no SL feedback information corresponding to the SL CG (e.g., has no SL feedback information corresponding to the PSFCH associated with the SL CG), the user does not multiplex the SL HARQ-ACK information on the PUSCH.

[0203] Or, adopt the following table and V in the above example UL T-SAI , VSL C-SAI Replace with. JPEG0007618860000003.jpg47170

[0204] Example 5: Semi-static time offset K1 belongs to dynamic time offset K1.

[0205] In one embodiment, the user equipment is configured with at least one SL configured grant type 1, and 1. This user equipment has monitoring DCI format 3_0 configured, and 2. This user equipment has SL configured grant type 2 configured; and 3. At least one SL configured grant type 2 is activated for this user equipment. The semi-static time offset corresponding to the SL configured grant type 1 should belong to the dynamic time offset.

[0206] In another embodiment, the user equipment is configured with at least one SL configured grant type1, and the codebook type is type1 or semi-static (e.g. pdsch-HARQ-ACK-Codebook=semi-static), and 1. This user equipment has monitoring DCI format 3_0 configured, and 2. This user equipment has SL configured grant type 2 configured; and 3. At least one SL configured grant type 2 is activated for this user equipment. The semi-static time offset corresponding to the SL configured grant type1 should belong to the dynamic time offset.

[0207] Example 6: Determine the number of bits of the SL feedback information.

[0208] For example, the slot determined based on the time offset K1 belongs to P sidelink resource pools, and includes the PSFCH resource, and the PSFCH period periodPSFCHresource of the resource pool pool_p in these P resource pools is N (PSFCH_p) When noted as such, the number of SL feedback information corresponding to this slot is JPEG0007618860000004.jpg13150, and α p represents the weight.

[0209] Also, for example, the slot determined based on the time offset K1 belongs to P sidelink resource pools, and includes the PSFCH resource, and these P resource pools are noted as {pool_0, pool_1, pool_2,..., pool_p,..., pool_(P - 1)}, where the PSFCH period periodPSFCHresource of the resource pool pool_p is N (PSFCH_p) When noted as such, the corresponding SL feedback information can be determined in the following way.

[0210] Traverse the P resource pools {pool_0, pool_1, pool_2,..., pool_p,..., pool_(P - 1)}, for example, in descending order or ascending order or other order of numbers, for example Set p = 0 For each resource pool pool_p, when p < P, enter the while cycle n F is set to 0, representing the index of the SL slot within one PSFCH period in the resource pool_p nF <N PSFCH If so, enter the while cycle. JPEG0007618860000005.jpg19150 while cycle ends p=p+1. Ends the while cycle.

[0211] Here, M A One interpretation of is that j is the PSSCH transmission occasion associated with the resource in which the SL feedback information is located, and j is used to represent the number of bits in the SL feedback information.
