[0042] In order to better understand the method for determining the number of time slots disclosed in an embodiment of the present disclosure, the communication system to which the embodiment of the present disclosure is applicable is first described below.

[0043] Please refer to Figure 1, which is a schematic diagram of the architecture of a communication system provided by an embodiment of the present disclosure. The communication system may include, but is not limited to, a network device and two terminals, which are connected via a SL. The number and form of the devices shown in Figure 1 are for example only and do not constitute a limitation on the embodiments of the present disclosure. In actual applications, two or more network devices and two or more terminals may be included. The communication system shown in Figure 1 includes, for example, a network device 11 and two terminals 12 and 13, wherein terminal 12 and terminal 13 are connected via a SL.

[0044] In this disclosure, terminal 12 may be a transmitting terminal, and terminal 13 may be a peer terminal. Terminal 13 may be one or more, and this disclosure does not limit this. Alternatively, terminal 13 may be a transmitting terminal, and terminal 12 may be a peer terminal. Terminal 12 may be one or more, and this disclosure does not limit this.

[0045] It should be noted that the technical solutions of the embodiments of the present disclosure can be applied to various communication systems. For example, long term evolution (LTE) systems, fifth generation (5G) mobile communication systems, 5G new radio (NR) systems, or other future new mobile communication systems. It should also be noted that the sidelink in the embodiments of the present disclosure can also be referred to as a sidelink or a through link.

[0046] The network device 11 in the embodiment of the present disclosure is an entity on the network side for transmitting or receiving signals. For example, the network device 11 can be an evolved NodeB (eNB), a transmission reception point (TRP), a next generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. The embodiment of the present disclosure does not limit the specific technology and specific device form adopted by the network device. The network device provided in the embodiment of the present disclosure can be composed of a centralized unit (CU) and a distributed unit (DU), wherein the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the network device, such as the base station, and the functions of some protocol layers are placed in the CU for centralized control, and the functions of the remaining part or all of the protocol layers are distributed in the DU, and the DC is centrally controlled by the CU.

[0047] The terminal in the embodiments of the present disclosure is an entity on the user side for receiving or transmitting signals, such as a mobile phone. The terminal may also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal may be a car with communication functions, a smart car, a mobile phone, a wearable device, a tablet computer (Pad), a computer with wireless transceiver functions, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. The embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

[0048] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0049] In order to support direct communication between terminals, the SL communication mode is introduced. Optionally, the interface between the terminals can be PC5.

[0050] Optionally, based on the correspondence between the transmitting terminal and the receiving terminal, three transmission modes are supported on the SL: unicast, multicast, and broadcast. Exemplarily, the transmitting terminal sends SL control information (Sidelink Control Information, SCI) on the PSCCH channel and sends the second-stage SCI on the PSSCH channel, such as the resource location of the transmission data and the source and destination identifiers. Exemplarily, for HARQ feedback-enabled data packets, the receiving terminal performs hybrid automatic repeat request-acknowledgement (HARQ-ACK) feedback on the PSSCH on the PSFCH channel.

[0051] In some embodiments, pre-configuration may be understood as definition, pre-definition, storage, pre-storage, pre-negotiation, curing, or pre-burning, etc.

[0052] Optionally, uplink and downlink operations can be performed in unlicensed bands, where both downlink and uplink channel access rely on the LBT feature. The wireless device or base station first "senses" the communication channel to detect the absence of communication before any transmission. When the communication channel is an unlicensed wideband carrier (e.g., several hundred megahertz), the LBT process relies on detecting energy levels across multiple sub-bands of the communication channel. Optionally, LBT parameters (such as type / duration, clear channel assessment parameters, etc.) can be configured on the wireless device by the base station.

[0053] In some embodiments, terms such as "uplink", "uplink", "physical uplink", etc. can be used interchangeably, and terms such as "downlink", "downlink", "physical downlink", etc. can be used interchangeably.

[0054] Optionally, a wireless device or base station must first "sense" the communication channel and detect that there is no communication before any transmission. LBT types include type 1 and type 2. Type 1 is based on a contention window, where a random number determines the channel monitoring duration. Access to the channel is only considered when the random number equals 0 and the channel is idle. Type 2 monitors the channel for a fixed period of time, such as 25us or 16us. Channel access priority class (CAPC) is a parameter related to LBT. Different CAPC values ​​affect the priority of the channel during contention, with smaller CAPC values ​​indicating higher priority.

[0055] SL communication can use unlicensed spectrum, and terminals sending SL data on unlicensed spectrum also need to perform LBT. The continuous LBT failure mechanism also applies to SL communication in unlicensed spectrum. In some embodiments, the terms "side," "sidelink," "side communication," "sidelink communication," "direct connection," "direct link," "direct communication," and "direct link communication" are interchangeable.

[0056] Optionally, for resource selection for single transmission block (TB) transmission, the media access control (MAC) layer needs to provide a set of parameters to the physical layer PHY. This set of parameters may include the remaining packet delay budget (PDB) and other related parameters that the physical layer needs to use when making resource selection.

[0057] Optionally, SL communication supports multi-continuous time slot transmission (MCSt), which reduces the impact of LBT on communication quality by transmitting in multiple consecutive time slots. A terminal can transmit in multiple consecutive time slots after successfully performing LTB.

[0058] Optionally, the multi-continuous time slot transmission of a single TB may refer to that a TB is repeatedly sent multiple times in several consecutive time slots, and the multi-continuous time slot transmission of multiple TBs may refer to that the transmission resources of multiple TBs are continuous in time slots.

[0059] Optionally, for multiple TBs, the MAC layer can trigger independent resource selection separately and pass a set of parameters to each TB separately. This set of parameters may include a parameter "the number of time slots for multi-continuous time slot transmission" submitted by the MAC layer to the physical layer. The physical layer can provide a candidate resource set for each TB. The candidate resources are multi-continuous time slot resources. The physical layer passes the "multi-continuous time slot" resource set to the MAC layer. The MAC layer performs resource selection separately in the candidate resource set corresponding to each TB, and the selected resources are multi-continuous time slot resources.

[0060] Optionally, for multiple TBs, the MAC layer can trigger resource selection only once and pass a single set of parameters for the multiple TBs. This set of parameters may include a parameter, "Number of consecutive time slot transmissions," which the MAC layer passes to the physical layer. Using this set of parameters, the physical layer can provide a candidate resource set for the multiple TBs. This candidate resource set consists of multiple consecutive time slots. The MAC layer selects a multi-slot resource from the candidate resource set. This multi-slot resource can be used to transmit multiple TBs, thus ensuring time-domain continuity for the multiple TBs.

[0061] However, the detailed method of how the terminal determines the number of time slots for multi-consecutive time slot transmission has not yet been clarified.

[0062] The following is a detailed description of a method and device for determining the number of time slots provided by the present disclosure with reference to the accompanying drawings.

[0063] In some embodiments, the method disclosed herein can be applied to unlicensed sidelink (SL-U) scenarios, and can also be applied to scenarios in other areas such as licensed spectrum where the problem of "how to determine the number of time slots for multiple consecutive time slot transmissions" is addressed.

[0064] Please refer to Figure 2, which is a flow chart of a method for determining the number of time slots provided by an embodiment of the present disclosure, and the method is executed by a terminal. As shown in Figure 2, the method may include but is not limited to the following steps:

[0065] Step 201: Determine the number of time slots for multiple consecutive time slot transmissions according to the logical channel parameters respectively associated with at least one TB.

[0066] In some embodiments, since the terminal has not yet performed the logical channel prioritization (LCP) process when the MAC layer submits the parameter "number of time slots for multi-continuous time slot transmission" to the physical layer, that is, packet assembly has not yet been performed, at least one TB can be determined by the terminal based on one or more of the cache status of the logical channel (LCH) to which data is to be sent, the logical channel priority, the size of the cached data, the remaining PDB, etc.

[0067] In some embodiments, the TB may be a sidelink media access control protocol data unit (SL MAC PDU), and the name of the TB is not limited.

[0068] In some embodiments, the logical channel parameters may include one or more of the following: CAPC; logical channel priority; PDB; remaining PDB.

[0069] In some embodiments, independent resource selection may be triggered for each TB, and the terminal may determine the number of time slots for the multi-continuous time slot transmission corresponding to each TB based on the logical channel parameters associated with each TB in at least one TB. The number of time slots for the multi-continuous time slot transmission corresponding to each TB may be the same or different.

[0070] In some embodiments, resource selection can be triggered once for at least one TB, and the terminal can determine the number of time slots for multi-continuous time slot transmission corresponding to at least one TB based on the logical channel parameters associated with at least one TB, that is, the number of time slots for the same multi-continuous time slot transmission corresponding to at least one TB.

[0071] Optionally, at least one TB can be determined based on one or more of the cache status of the LCH to which data is to be sent, the logical channel priority, the size of the cached data, and the remaining PDBs, and the number of time slots for multi-continuous time slot transmission can be determined based on the logical channel parameters of the LCH to which data is to be sent.

[0072] In some embodiments, the number of time slots for a multi-continuous time slot transmission determined based on the logical channel parameters of the LCH to which data is to be transmitted may be the number of time slots to which at least one TB corresponds for the multi-continuous time slot transmission. Exemplarily, the number of time slots to which at least one TB corresponds for the multi-continuous time slot transmission may be understood as at least one TB corresponding to the same number of time slots. The MAC layer submits the parameter to the physical layer, the physical layer provides a candidate resource set for the at least one TB, and the MAC layer selects a multi-slot resource from the candidate resource set, and the multi-slot resource is used to transmit the at least one TB.

[0073] In some embodiments, the number of time slots for the multi-continuous time slot transmission determined based on the logical channel parameters of the LCH to which data is to be transmitted may be the number of time slots for each TB corresponding to the multi-continuous time slot transmission, and the number of time slots for the multi-continuous time slot transmission corresponding to different TBs may be the same. Exemplarily, for each TB, the MAC layer submits a parameter for the number of time slots for the multi-continuous time slot transmission corresponding to the TB to the physical layer. The physical layer provides a candidate resource set for each TB, and the MAC layer selects a multi-slot resource from the candidate resource set corresponding to each TB.

[0074] As an example, the number of time slots for the multi-continuous time slot transmission may be determined according to any one of the minimum value, maximum value, median value, or average value of the CAPC of the LCH to be transmitted.

[0075] As another example, the number of time slots for multi-continuous time slot transmission may be determined according to any one of the minimum value, maximum value, median value, or average value of the logical channel priority of the LCH to which data is to be transmitted.

[0076] As another example, the number of time slots for the multi-continuous time slot transmission may be determined according to any one of the minimum value, maximum value, median value, or average value of the PDB of the LCH to transmit data.

[0077] As another example, the number of time slots for the multi-continuous time slot transmission may be determined according to any one of the minimum value, maximum value, median value, or average value of the remaining PDBs of the LCHs to transmit data.

[0078] In this embodiment or example, the optional modes or optional examples may be arbitrarily combined unless there is any contradiction.

[0079] In an embodiment of the present disclosure, the terminal can determine the number of time slots for multi-continuous time slot transmission based on the logical channel parameters associated with at least one TB, thereby improving the accuracy of the number of time slots for multi-continuous time slot transmission and providing a basis for the selection of multi-continuous time slot transmission resources.

[0080] Please refer to Figure 3, which is a flow chart of another method for determining the number of time slots provided by an embodiment of the present disclosure, which is executed by a terminal. As shown in Figure 3, the method may include but is not limited to the following steps:

[0081] Step 301 : Determine the number of time slots for multiple consecutive time slot transmissions corresponding to each TB according to the CAPC associated with each TB in at least one TB.

[0082] The explanation of at least one TB in this embodiment can be found in the above embodiment, so it will not be repeated here.

[0083] Optionally, since the terminal has not yet executed the LCP process when the MAC layer submits the parameter "number of time slots for multi-continuous time slot transmission" to the physical layer, that is, packet assembly has not yet been performed, at least one TB can be determined by the terminal based on one or more of the cache status of the LCH to be sent, the logical channel priority, the size of the cached data, the remaining PDB, etc.

[0084] In some embodiments, independent resource selection may be triggered for at least one TB, and the terminal may determine the number of time slots for the multi-continuous time slot transmission corresponding to each TB based on the CAPC associated with each TB in the at least one TB. The number of time slots for the multi-continuous time slot transmission corresponding to each TB may be the same or different.

[0085] For example, the terminal may determine the CAPC associated with each TB and, based on a preset correspondence between the CAPC and the number of time slots, determine the number of time slots for continuous transmission of multiple consecutive time slots corresponding to each TB. For example, the higher the CAPC associated with the TB, the greater the number of time slots for continuous transmission of multiple consecutive time slots corresponding to the TB. There may be other preset correspondences between the CAPC and the number of time slots, which are not specifically limited in this disclosure.

[0086] Optionally, the first TB in at least one TB only includes a sidelink media access control element (SL MAC CE), and the highest priority CAPC is determined to be the CAPC associated with the first TB, where the value of the highest priority CAPC is the lowest. The first TB may be any TB in at least one TB. Exemplarily, the TB may be an SL MAC PDU. If the SL MAC PDU only includes an SL MAC CE, the CAPC of the SL MAC PDU is the highest priority (i.e., the CAPC has the lowest value), and the terminal may determine the number of time slots for multi-continuous time slot transmission of the SL MAC PDU based on the highest priority of the CAPC.

[0087] Optionally, the first TB in at least one TB includes a sidelink control channel service data unit (SCCH SDU), and the highest priority CAPC is determined to be the CAPC associated with the first TB, where the value of the highest priority CAPC is the lowest. The first TB may be any TB in at least one TB. Exemplarily, the TB may be a SL MAC PDU. If the SL MAC PDU includes an SCCH SDU, the CAPC of the SL MAC PDU is the highest priority (i.e., the CAPC value is the lowest). The terminal may determine the number of time slots for the multi-continuous time slot transmission corresponding to the SL MAC PDU based on the highest priority of the CAPC.

[0088] Optionally, a first TB in the at least one TB includes an SL MAC SDU, and any one of a minimum value, a maximum value, a median value, or an average value of a CAPC associated with a logical channel LCH multiplexed to the first TB is determined as the CAPC associated with the first TB. The first TB may be any TB in the at least one TB.

[0089] Exemplarily, the TB may be a SL MAC PDU. If the SL MAC PDU includes a SL MAC SDU, the terminal may determine the number of time slots for the multi-continuous time slot transmission corresponding to the SL MAC PDU based on any one of the maximum value, minimum value, median value, and average value of the CAPC associated with the LCH multiplexed into the SL MAC PDU. Exemplarily, the LCH multiplexed into the SL MAC PDU may refer to the LCH on which data is multiplexed into the SL MAC PDU. For example, if data on three LCHs is multiplexed into a certain SL MAC PDU, then the number of time slots for the multi-continuous time slot transmission corresponding to the SL MAC PDU may be determined based on the maximum value of the CAPC associated with these three LCHs.

[0090] In the embodiment of the present disclosure, when at least one TB triggers independent resource selection, the terminal can determine the number of time slots for multi-continuous time slot transmission corresponding to each TB based on the CAPC associated with each TB, thereby realizing multi-continuous time slot transmission of a single TB.

[0091] Please refer to Figure 4, which is a flow chart of another method for determining the number of time slots provided by an embodiment of the present disclosure, which is executed by a terminal. As shown in Figure 4, the method may include but is not limited to the following steps:

[0092] Step 401 : Determine the number of time slots for multiple consecutive time slot transmissions corresponding to each TB according to the logical channel priority associated with each TB in at least one TB.

[0093] The explanation of at least one TB in this embodiment can be found in the above embodiment, so it will not be repeated here.

[0094] Optionally, since the terminal has not yet executed the LCP process when the MAC layer submits the parameter "number of time slots for multi-continuous time slot transmission" to the physical layer, that is, packet assembly has not yet been performed, at least one TB can be determined by the terminal based on one or more of the cache status of the LCH to be sent, the logical channel priority, the size of the cached data, the remaining PDB, etc.

[0095] In some embodiments, independent resource selection can be triggered for each TB separately, and the terminal can determine the number of time slots for the multi-continuous time slot transmission corresponding to each TB based on the logical channel priority associated with each TB. Exemplarily, the terminal can determine the logical channel priority associated with each TB, and determine the number of time slots for the multi-continuous time slot continuous transmission corresponding to each TB based on the preset correspondence between the logical channel priority and the number of time slots. For example, the higher the logical channel priority associated with the TB, the greater the number of time slots for the multi-continuous time slot continuous transmission corresponding to the TB. There may be other preset correspondences between logical channel priorities and the number of time slots, and this disclosure does not specifically limit this.

[0096] Optionally, the terminal can determine the logical channel priority associated with each TB based on any one of the minimum value, maximum value, median value or average value of the logical channel priority of the SL LCH and / or SL MAC CE contained in each TB, and determine the number of time slots for multi-continuous time slot transmission corresponding to each TB based on the logical channel priority associated with each TB.

[0097] For example, the minimum value of the logical channel priorities of the SL LCH and / or SL MAC CE contained in each TB, that is, the highest logical channel priority, can be determined as the logical channel priority associated with each TB. In other words, the number of time slots for the multi-continuous time slot transmission corresponding to each TB can be determined based on the highest logical channel priority among the logical channel priorities of the SL LCH and / or SL MAC CE contained in each TB.

[0098] In an embodiment of the present disclosure, for the case where at least one TB triggers independent resource selection respectively, the terminal can determine the number of time slots for multi-continuous time slot transmission corresponding to each TB based on the logical channel priority associated with each TB, thereby realizing multi-continuous time slot transmission of a single TB.

[0099] Please refer to Figure 5, which is a flowchart of another method for determining the number of time slots provided by an embodiment of the present disclosure, and the method is executed by a terminal. As shown in Figure 5, the method may include but is not limited to the following steps:

[0100] Step 501 : Determine the number of time slots for multi-continuous time slot transmission corresponding to each TB according to the PDB associated with each TB in at least one TB.

[0101] The explanation of at least one TB in this embodiment can be found in the above embodiment, so it will not be repeated here.

[0102] Optionally, since the terminal has not yet executed the LCP process when the MAC layer submits the parameter "number of time slots for multi-continuous time slot transmission" to the physical layer, that is, packet assembly has not yet been performed, at least one TB can be determined by the terminal based on one or more of the cache status of the LCH to be sent, the logical channel priority, the size of the cached data, the remaining PDB, etc.

[0103] In some embodiments, independent resource selection can be triggered for at least one TB, and the terminal can determine the number of time slots for the multi-continuous time slot transmission corresponding to each TB based on the PDB associated with each TB in the at least one TB. For example, the terminal can determine the PDB associated with each TB and, based on a preset correspondence between the PDB and the number of time slots, determine the number of time slots for the multi-continuous time slot transmission corresponding to each TB. For example, the larger the PDB associated with the TB, the greater the number of time slots for the multi-continuous time slot transmission corresponding to the TB. Other preset correspondences between PDBs and the number of time slots are possible, and this disclosure does not specifically limit this.

[0104] Optionally, the terminal can determine any one of the minimum value, maximum value, intermediate value or average value of the PDB of the SL LCH and / or SL MAC CE contained in each TB as the PDB associated with each TB, and determine the number of time slots for the multi-continuous time slot transmission corresponding to each TB based on the PDB associated with each TB.

[0105] For example, the minimum value among the PDBs of the SL LCH and / or SL MAC CE contained in each TB, that is, the minimum PDB, can be determined as the PDB associated with each TB. In other words, the number of time slots for the multi-continuous time slot transmission corresponding to each TB can be determined based on the minimum PDB among the PDBs of the SL LCH and / or the PDBs of the SL MAC CE contained in each TB.

[0106] In an embodiment of the present disclosure, for the case where at least one TB triggers independent resource selection respectively, the terminal can determine the number of time slots for multi-continuous time slot transmission corresponding to each TB based on the PDB associated with each TB, thereby realizing multi-continuous time slot transmission of a single TB.

[0107] Please refer to Figure 6, which is a flow chart of another method for determining the number of time slots provided by an embodiment of the present disclosure, which is executed by a terminal. As shown in Figure 6, the method may include but is not limited to the following steps:

[0108] Step 601 : Determine the number of time slots for multiple consecutive time slot transmissions corresponding to each TB according to the remaining PDBs associated with each TB in at least one TB.

[0109] The explanation of at least one TB in this embodiment can be found in the above embodiment, so it will not be repeated here.

[0110] Optionally, since the terminal has not yet executed the LCP process when the MAC layer submits the parameter "number of time slots for multi-continuous time slot transmission" to the physical layer, that is, packet assembly has not yet been performed, at least one TB can be determined by the terminal based on one or more of the cache status of the LCH to be sent, the logical channel priority, the size of the cached data, the remaining PDB, etc.

[0111] In some embodiments, independent resource selection can be triggered for at least one TB, and the terminal can determine the number of time slots for multi-continuous time slot transmission corresponding to each TB based on the remaining PDB associated with each TB in the at least one TB. Exemplarily, the terminal can determine the remaining PDB associated with each TB, and determine the number of time slots for multi-continuous time slot continuous transmission corresponding to each TB based on a preset correspondence between the remaining PDB and the number of time slots. For example, the larger the remaining PDB associated with the TB, the greater the number of time slots for multi-continuous time slot continuous transmission corresponding to the TB. There may be other preset correspondences between the remaining PDB and the number of time slots, and this disclosure does not specifically limit this.

[0112] Optionally, the terminal can determine the remaining PDB associated with each TB based on any one of the minimum value, maximum value, median value or average value of the remaining PDB of the SL LCH and / or SL MAC CE contained in each TB, and determine the number of time slots for multi-continuous time slot transmission corresponding to each TB based on the remaining PDB associated with each TB.

[0113] For example, the minimum value among the remaining PDBs of the SL LCH and / or SL MAC CE contained in each TB, that is, the minimum remaining PDB, can be determined as the remaining PDB associated with each TB. In other words, the number of time slots for the multi-continuous time slot transmission corresponding to each TB can be determined based on the minimum remaining PDB among the remaining PDBs of the SL LCH and / or SL MAC CE contained in each TB.

[0114] In an embodiment of the present disclosure, for the case where at least one TB triggers independent resource selection respectively, the terminal can determine the number of time slots for multi-continuous time slot transmission corresponding to each TB based on the remaining PDBs associated with each TB, thereby realizing multi-continuous time slot transmission of a single TB.

[0115] Please refer to Figure 7, which is a flowchart of another method for determining the number of time slots provided by an embodiment of the present disclosure, and the method is executed by a terminal. As shown in Figure 7, the method may include but is not limited to the following steps:

[0116] Step 701: Determine a target CAPC based on the CAPCs associated with at least one TB.

[0117] The explanation of at least one TB in this embodiment can be found in the above embodiment, so it will not be repeated here.

[0118] Optionally, since the terminal has not yet executed the LCP process when the MAC layer submits the parameter "number of time slots for multi-continuous time slot transmission" to the physical layer, that is, packet assembly has not yet been performed, at least one TB can be determined by the terminal based on one or more of the cache status of the LCH to be sent, the logical channel priority, the size of the cached data, the remaining PDB, etc.

[0119] In some embodiments, resource selection may be triggered once for at least one TB, and the terminal may determine a target CAPC according to CAPCs respectively associated with the at least one TB.

[0120] Optionally, the terminal may determine the target CAPC based on any one of the minimum value, maximum value, median value, or average value of the CAPCs associated with at least one TB. For example, the minimum value of the CAPCs associated with at least one TB, that is, the highest-priority CAPC among the CAPCs associated with at least one TB, may be determined as the target CAPC.

[0121] Optionally, the terminal may determine a CAPC associated with any TB in the at least one TB as the target CAPC.

[0122] Optionally, the method for determining the CAPC associated with each TB can refer to the above embodiment, so it is not repeated here.

[0123] Step 702: Determine the number of time slots for multiple consecutive time slot transmissions corresponding to at least one TB according to the target CAPC.

[0124] In some embodiments, the terminal may determine the number of time slots for multiple consecutive time slot transmissions corresponding to at least one TB according to the target CAPC.

[0125] In some embodiments, resource selection can be triggered for at least one TB. The terminal can determine a target CAPC based on the CAPC associated with each TB in the at least one TB, and further determine the number of time slots for the multi-continuous time slot transmission corresponding to the at least one TB based on the target CAPC. Exemplarily, the terminal can determine the target CAPC and, based on a preset correspondence between the CAPC and the number of time slots, determine the number of time slots for the multi-continuous time slot transmission corresponding to the at least one TB. For example, a larger CAPC corresponds to a greater number of time slots for the multi-continuous time slot transmission. There may be other preset correspondences between the CAPC and the number of time slots, and this disclosure does not specifically limit this.

[0126] In some embodiments, the number of time slots for multi-continuous time slot transmission corresponding to at least one TB can be understood as at least one TB corresponding to the same number of time slots. The MAC layer submits the parameter to the physical layer, and the physical layer provides a candidate resource set for at least one TB. The MAC layer selects multi-slot resources from the candidate resource set, and the multi-slot resources are used to send at least one TB.

[0127] As an example, the terminal may determine the number of time slots for multi-continuous time slot transmission corresponding to at least one TB based on the minimum value of the CAPC associated with at least one TB. For example, if there are three TBs transmitted via multi-slot resources, the CAPC values ​​of the three TBs are TB1=1, TB2=3, and TB3=2, respectively, and the minimum value of the CAPCs of the three TBs is 1, the terminal may determine the number of time slots for multi-continuous time slot transmission corresponding to the three TBs based on the minimum CAPC value of 1.

[0128] As another example, the terminal may determine the number of time slots for multi-continuous time slot transmission corresponding to at least one TB based on the maximum value of the CAPC associated with at least one TB. For example, if a total of three TBs are transmitted using multi-slot resources, the CAPC values ​​of the three TBs are TB1=1, TB2=3, and TB3=2, respectively, and the maximum value of the CAPCs among the three TBs is 3, the terminal may determine the number of time slots for multi-continuous time slot transmission corresponding to the three TBs based on the maximum value of the CAPC, 3.

[0129] As another example, the terminal may determine the number of time slots for multi-continuous time slot transmission corresponding to at least one TB based on the median value of the CAPC associated with at least one TB. For example, if a total of three TBs are transmitted using multi-slot resources, the CAPC values ​​of the three TBs are TB1=1, TB2=3, and TB3=2, respectively, and the median value of the CAPC of the three TBs is 2, the terminal may determine the number of time slots for multi-continuous time slot transmission corresponding to the three TBs based on the median value of the CAPC, 2.

[0130] The method for determining the number of time slots involved in the embodiments of the present disclosure may include at least one of steps 701 and 702. For example, step 701 may be implemented as an independent embodiment, step 702 may be implemented as an independent embodiment, and step 701 + step 702 may be implemented as independent embodiments, but the present invention is not limited thereto.

[0131] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, and the optional methods or optional examples can be arbitrarily combined.

[0132] In an embodiment of the present disclosure, for the case where at least one TB triggers a resource selection, the terminal can determine the target CAPC based on the CAPC associated with the at least one TB, and determine the number of time slots for the multi-continuous time slot transmission corresponding to the at least one TB based on the target CAPC, thereby realizing multi-continuous time slot transmission of multiple TBs.

[0133] Please refer to Figure 8, which is a flowchart of another method for determining the number of time slots provided by an embodiment of the present disclosure, which is executed by a terminal. As shown in Figure 8, the method may include but is not limited to the following steps:

[0134] Step 801: Determine a target logical channel priority according to the logical channel priority associated with at least one TB.

[0135] The explanation of at least one TB in this embodiment can be found in the above embodiment, so it will not be repeated here.

[0136] Optionally, since the terminal has not yet executed the LCP process when the MAC layer submits the parameter "number of time slots for multi-continuous time slot transmission" to the physical layer, that is, packet assembly has not yet been performed, at least one TB can be determined by the terminal based on one or more of the cache status of the LCH to be sent, the logical channel priority, the size of the cached data, the remaining PDB, etc.

[0137] In some embodiments, resource selection may be triggered once for at least one TB, and the terminal may determine the target logical channel priority according to the logical channel priorities respectively associated with the at least one TB.

[0138] Optionally, the terminal may determine any one of the minimum value, maximum value, intermediate value, or average value of the logical channel priorities respectively associated with at least one TB as the target logical channel priority. For example, the minimum value of the logical channel priorities respectively associated with at least one TB, that is, the highest logical channel priority among the logical channel priorities respectively associated with at least one TB, may be determined as the target logical channel priority.

[0139] Optionally, the terminal may determine the logical channel priority associated with any TB in at least one TB as the target logical channel priority.

[0140] Optionally, the method for determining the priority of the logical channel associated with each TB can be referred to in the above embodiment, so it will not be repeated here.

[0141] Step 802: Determine the number of time slots for multiple consecutive time slot transmissions corresponding to at least one TB according to the target logical channel priority.

[0142] In some embodiments, the terminal may determine the number of time slots for multiple consecutive time slot transmissions corresponding to at least one TB based on the target logical channel priority.

[0143] In some embodiments, resource selection can be triggered once for at least one TB, and the terminal can determine the target logical channel priority based on the logical channel priority associated with each TB in the at least one TB, and further determine the number of time slots for the multi-continuous time slot transmission corresponding to the at least one TB based on the target logical channel priority. Exemplarily, the terminal can determine the target logical channel priority and determine the number of time slots for the multi-continuous time slot continuous transmission corresponding to the at least one TB based on the correspondence between the preset logical channel priority and the number of time slots, such as the higher the logical channel priority, the greater the number of time slots for the multi-continuous time slot continuous transmission corresponding to the at least one TB. There may be other preset correspondences between logical channel priorities and the number of time slots, and the present disclosure does not make specific limitations on this.

[0144] In some embodiments, the number of time slots for multi-continuous time slot transmission corresponding to at least one TB can be understood as at least one TB corresponding to the same number of time slots. The MAC layer submits the parameter to the physical layer, and the physical layer provides a candidate resource set for at least one TB. The MAC layer selects multi-slot resources from the candidate resource set, and the multi-slot resources are used to send at least one TB.

[0145] The method for determining the number of time slots involved in the embodiment of the present disclosure may include at least one of steps 801 and 802. For example, step 801 may be implemented as an independent embodiment, step 802 may be implemented as an independent embodiment, and step 801 + step 802 may be implemented as independent embodiments, but the present invention is not limited thereto.

[0146] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, and the optional methods or optional examples can be arbitrarily combined.

[0147] In an embodiment of the present disclosure, for the case where at least one TB triggers a resource selection, the terminal can determine the target logical channel priority based on the logical channel priority associated with at least one TB, and determine the number of time slots for the multi-continuous time slot transmission corresponding to at least one TB based on the target logical channel priority, thereby realizing multi-continuous time slot transmission of multiple TBs.

[0148] Please refer to Figure 9, which is a flowchart of another method for determining the number of time slots provided by an embodiment of the present disclosure, and the method is executed by a terminal. As shown in Figure 9, the method may include but is not limited to the following steps:

[0149] Step 901: Determine a target PDB based on PDBs associated with at least one TB.

[0150] The explanation of at least one TB in this embodiment can be found in the above embodiment, so it will not be repeated here.

[0151] Optionally, since the terminal has not yet executed the LCP process when the MAC layer submits the parameter "number of time slots for multi-continuous time slot transmission" to the physical layer, that is, packet assembly has not yet been performed, at least one TB can be determined by the terminal based on one or more of the cache status of the LCH to be sent, the logical channel priority, the size of the cached data, the remaining PDB, etc.

[0152] In some embodiments, resource selection may be triggered once for at least one TB, and the terminal may determine a target PDB based on PDBs associated with the at least one TB.

[0153] Optionally, the terminal may determine any one of the minimum value, maximum value, median value, or average value of the PDBs associated with at least one TB as the target PDB. For example, the minimum value of the PDBs associated with at least one TB, that is, the smallest PDB among the PDBs associated with at least one TB, may be determined as the target PDB.

[0154] Optionally, the terminal may determine a PDB associated with any TB in the at least one TB as the target PDB.

[0155] Optionally, the method for determining the PDB associated with each TB can be found in the above embodiment, so it is not repeated here.

[0156] Step 902: Determine the number of time slots for multiple consecutive time slot transmissions corresponding to at least one TB according to the target PDB.

[0157] In some embodiments, the terminal may determine the number of time slots for multiple consecutive time slot transmissions corresponding to at least one TB based on the target PDB.

[0158] In some embodiments, resource selection can be triggered once for at least one TB, and the terminal can determine the target PDB based on the PDB associated with each TB in the at least one TB, and further determine the number of time slots for the multi-continuous time slot transmission corresponding to the at least one TB based on the target PDB. Exemplarily, the terminal can determine the target PDB and determine the number of time slots for the multi-continuous time slot continuous transmission corresponding to the at least one TB based on the correspondence between the preset PDB and the number of time slots, such as the larger the PDB, the greater the number of time slots for the multi-continuous time slot continuous transmission corresponding to the at least one TB. There may be other preset correspondences between PDBs and the number of time slots, and the present disclosure does not specifically limit this.

[0159] In some embodiments, the number of time slots for multi-continuous time slot transmission corresponding to at least one TB can be understood as at least one TB corresponding to the same number of time slots. The MAC layer submits the parameter to the physical layer, and the physical layer provides a candidate resource set for at least one TB. The MAC layer selects multi-slot resources from the candidate resource set, and the multi-slot resources are used to send at least one TB.

[0160] The method for determining the number of time slots involved in the embodiments of the present disclosure may include at least one of steps 901 and 902. For example, step 901 may be implemented as an independent embodiment, step 902 may be implemented as an independent embodiment, and step 901 + step 902 may be implemented as independent embodiments, but the present invention is not limited thereto.

[0161] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, and the optional methods or optional examples can be arbitrarily combined.

[0162] In an embodiment of the present disclosure, for the case where at least one TB triggers a resource selection, the terminal can determine the target PDB based on the PDBs associated with the at least one TB, and determine the number of time slots for the multi-continuous time slot transmission corresponding to the at least one TB based on the target PDB, thereby realizing multi-continuous time slot transmission of multiple TBs.

[0163] Please refer to Figure 10, which is a flowchart of another method for determining the number of time slots provided by an embodiment of the present disclosure, and the method is executed by a terminal. As shown in Figure 10, the method may include but is not limited to the following steps:

[0164] Step 1001: Determine a target remaining PDB according to remaining PDBs respectively associated with at least one TB.

[0165] The explanation of at least one TB in this embodiment can be found in the above embodiment, so it will not be repeated here.

[0166] Optionally, since the terminal has not yet executed the LCP process when the MAC layer submits the parameter "number of time slots for multi-continuous time slot transmission" to the physical layer, that is, packet assembly has not yet been performed, at least one TB can be determined by the terminal based on one or more of the cache status of the LCH to be sent, the logical channel priority, the size of the cached data, the remaining PDB, etc.

[0167] In some embodiments, resource selection may be triggered once for at least one TB, and the terminal may determine a target remaining PDB based on the remaining PDBs respectively associated with the at least one TB.

[0168] Optionally, the terminal may determine any one of the minimum value, maximum value, median value, or average value of the remaining PDBs associated with at least one TB as the target remaining PDB. For example, the minimum value of the remaining PDBs associated with at least one TB, that is, the smallest remaining PDB among the remaining PDBs associated with at least one TB, may be determined as the target remaining PDB.

[0169] Optionally, the terminal may determine a remaining PDB associated with any TB in the at least one TB as the target remaining PDB.

[0170] Optionally, the method for determining the remaining PDBs associated with each TB can be found in the above embodiment, so it is not described again here.

[0171] Step 1002: Determine the number of time slots for multiple consecutive time slot transmissions corresponding to at least one TB according to the target remaining PDB.

[0172] In some embodiments, the terminal may determine the number of time slots for multiple consecutive time slot transmissions corresponding to at least one TB based on the target remaining PDB.

[0173] In some embodiments, a resource selection may be triggered for at least one TB, and the terminal may determine a target remaining PDB based on the remaining PDB associated with each TB in the at least one TB, and further determine the number of time slots for multi-continuous time slot transmission corresponding to the at least one TB based on the target remaining PDB. Exemplarily, the terminal may determine the target remaining PDB, and determine the number of time slots for multi-continuous time slot continuous transmission corresponding to the at least one TB based on a preset correspondence between the remaining PDB and the number of time slots, such as the larger the remaining PDB, the greater the number of time slots for multi-continuous time slot continuous transmission corresponding to the at least one TB. There may be other preset correspondences between the remaining PDB and the number of time slots, and the present disclosure does not specifically limit this.

[0174] In some embodiments, the number of time slots for multi-continuous time slot transmission corresponding to at least one TB can be understood as at least one TB corresponding to the same number of time slots. The MAC layer submits the parameter to the physical layer, and the physical layer provides a candidate resource set for at least one TB. The MAC layer selects multi-slot resources from the candidate resource set, and the multi-slot resources are used to send at least one TB.

[0175] The method for determining the number of time slots involved in the embodiments of the present disclosure may include at least one of steps 1001 and 1002. For example, step 1001 may be implemented as an independent embodiment, step 1002 may be implemented as an independent embodiment, and step 1001 + step 1002 may be implemented as independent embodiments, but the present invention is not limited thereto.

[0176] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, and the optional methods or optional examples can be arbitrarily combined.

[0177] In an embodiment of the present disclosure, for the case where at least one TB triggers a resource selection, the terminal can determine the target remaining PDB based on the remaining PDBs associated with the at least one TB, and determine the number of time slots for the multi-continuous time slot transmission corresponding to the at least one TB based on the target remaining PDB, thereby realizing multi-continuous time slot transmission of multiple TBs.

[0178] In some embodiments, the method for determining the number of time slots disclosed herein may further include: determining that a buffer size of data currently to be sent exceeds a preset threshold, and enabling transmission of multiple consecutive time slots.

[0179] Optionally, the preset threshold can be obtained through network configuration or pre-configuration. Exemplarily, for a terminal in a connected state, the network device can configure the preset threshold through dedicated signaling; for a terminal in an idle state (IDLE) or an inactive state (INACTIVE), the network device can configure the preset threshold through a system information block (SIB); for a terminal in an out-of-range (OOC) state, the network device can configure the preset threshold through pre-configuration. Exemplarily, the preset threshold can be determined by the terminal implementation.

[0180] Optionally, if the current buffer size of data to be sent exceeds a preset threshold, after the terminal enables multi-consecutive time slot transmission, the terminal may adopt any of the above-mentioned methods to determine the number of time slots for multi-consecutive time slot transmission.

[0181] In some embodiments, the method for determining the number of time slots disclosed herein may further include: measuring a channel busy ratio (CBR) of at least one resource pool to obtain a CBR measurement result corresponding to each resource pool in the at least one resource pool; and enabling multi-continuous time slot transmission for the first resource pool when the CBR measurement result corresponding to a first resource pool in the at least one resource pool satisfies a first threshold condition. Exemplarily, the first resource pool may refer to any resource pool in the at least one resource pool.

[0182] Enabling multiple consecutive time slot transmission for the first resource pool can be understood as adopting multiple consecutive time slot transmission when using resources on the first resource pool to send TB.

[0183] Optionally, the first threshold condition may be greater than a first preset threshold, or may be less than or equal to the first preset threshold, which is not limited in the present disclosure.

[0184] Optionally, the first preset threshold value can be obtained through network configuration or pre-configuration. Exemplarily, for a terminal in a connected state, the network device can configure the first preset threshold value through dedicated signaling; for a terminal in an idle state (IDLE) or an inactive state (INACTIVE), the network device can configure the first preset threshold value through a SIB; for a terminal in an OOC state, the network device configures the first preset threshold value through pre-configuration. Exemplarily, the first preset threshold value can be determined by the terminal implementation.

[0185] Optionally, if the CBR measurement result corresponding to the first resource pool meets the first threshold condition, after the terminal enables multi-continuous time slot transmission for the first resource pool, the terminal can use any of the above methods to determine the number of time slots for multi-continuous time slot transmission.

[0186] In some embodiments, the method for determining the number of time slots disclosed herein may further include: measuring a received signal strength indicator (RSSI) of at least one resource pool to obtain an RSSI measurement result corresponding to each resource pool in the at least one resource pool; and enabling multi-continuous time slot transmission for the second resource pool when the RSSI measurement result corresponding to a second resource pool in the at least one resource pool meets a second threshold condition. Exemplarily, the second resource pool may refer to any resource pool in the at least one resource pool.

[0187] Enabling multiple consecutive time slot transmission for the second resource pool can be understood as adopting multiple consecutive time slot transmission when using resources on the second resource pool to send TB.

[0188] Optionally, the second threshold condition may be greater than a second preset threshold, or may be less than or equal to the second preset threshold, which is not limited in the present disclosure.

[0189] Optionally, the second preset threshold value can be obtained through network configuration or pre-configuration. Exemplarily, for a terminal in a connected state, the network device can configure the second preset threshold value through dedicated signaling; for a terminal in an idle state (IDLE) or an inactive state (INACTIVE), the network device can configure the second preset threshold value through a SIB; for a terminal in an OOC state, the network device configures the second preset threshold value through pre-configuration. Exemplarily, the second preset threshold value can be determined by the terminal implementation.

[0190] Optionally, if the RSSI measurement result corresponding to the second resource pool meets the second threshold condition, after the terminal enables multi-continuous time slot transmission for the second resource pool, the terminal can use any of the above methods to determine the number of time slots for multi-continuous time slot transmission.

[0191] In some embodiments, the above-mentioned terminal may be a first terminal, and the method for determining the number of time slots disclosed herein may further include: obtaining multi-slot resources based on the number of time slots transmitted in multiple consecutive time slots; and sending one or more TBs to the second terminal through the multi-slot resources.

[0192] Optionally, the first terminal may determine a candidate resource set based on the number of time slots transmitted in multiple consecutive time slots, perform resource selection on the candidate resource set to obtain multi-slot resources, and send the one or more TBs to the second terminal via the multi-slot resources.

[0193] Exemplarily, if independent resource selection is triggered for at least one TB, resource selection is performed on the candidate resource set corresponding to each TB, and multi-slot resources corresponding to each TB can be obtained.

[0194] Exemplarily, if resource selection is triggered once for at least one TB, resource selection is performed on a candidate resource set corresponding to the at least one TB, and multi-slot resources corresponding to the at least one TB can be obtained.

[0195] In the present disclosure, the above embodiments or optional methods or optional examples may be arbitrarily combined unless there is any contradiction.

[0196] To facilitate understanding of the method for determining the number of time slots disclosed herein, the following embodiments are used for illustration:

[0197] Optional embodiment: The terminal determines the number of time slots for multi-continuous time slot transmission according to the minimum value of the CAPC associated with one or more TBs.

[0198] Optionally, the terminal determines the CAPC of one or more TBs according to the following criteria: A TB transport block can also be referred to as a MAC PDU. The one or more TBs are one or more TBs transmitted via the multi-slot resource.

[0199] Exemplarily, if the SL MAC PDU only includes the SL MAC CE, the CAPC of the SL MAC PDU has the highest priority (the lowest CAPC value).

[0200] Exemplarily, if the SL MAC PDU contains a SCCH SDU, the CAPC of the SL MAC PDU has the highest priority (lowest CAPC value).

[0201] Exemplarily, if the SL MAC PDU contains a SL MAC SDU, the CAPC of the SL MAC PDU is the lowest priority CAPC associated with the logical channel multiplexed to this TB (CAPC is configured per logical channel) regardless of whether the SL MAC PDU contains a SL MAC CE.

[0202] Exemplarily, the terminal determines the number of time slots for multi-continuous time slot transmission based on the minimum value of the CAPC associated with the one or more TBs. For example, if there are 3 TBs transmitted through multi-continuous time slot resources, and the CAPCs of the 3 TBs are TB1=1, TB2=3, and TB3=2, the terminal determines the number of time slots for multi-continuous time slot transmission based on CAPC priority 1.

[0203] In an optional embodiment, the terminal determines the number of time slots for multi-continuous time slot transmission according to the maximum value of the CAPC associated with one or more TBs.

[0204] Optionally, the terminal determines the number of time slots for multi-continuous time slot transmission based on the maximum value of the CAPC associated with the one or more TBs. For example, if there are 3 TBs transmitted through multi-continuous time slot resources, and the CAPCs of the 3 TBs are TB1=1, TB2=3, and TB3=2, the terminal determines the number of time slots for multi-continuous time slot transmission based on CAPC priority 3. Specifically, when submitting this parameter, the terminal has not yet performed the LCP process, that is, no packet has been assembled, so the one or more TBs are determined by the terminal based on the cache status of the LCH with data to be sent.

[0205] Optional embodiment: The terminal determines the number of time slots for multi-continuous time slot transmission according to the median value / average value of CAPC associated with one or more TBs.

[0206] Optionally, the terminal determines the number of time slots for multi-continuous time slot transmission based on the median value of the CAPC associated with the one or more TBs. For example, if there are 3 TBs transmitted through multi-continuous time slot resources, and the CAPCs of the 3 TBs are TB1=1, TB2=3, and TB3=2, the terminal determines the number of time slots for multi-continuous time slot transmission based on CAPC priority 2.

[0207] In an optional embodiment, the terminal randomly selects a CAPC associated with one or more TBs to determine the number of time slots for multi-continuous time slot transmission.

[0208] Optionally, the terminal implements a random selection of a CAPC associated with one or more TBs to determine the number of time slots for multi-continuous time slot transmission. For example, if there are three TBs transmitted using multi-continuous time slot resources, and the CAPCs of the three TBs are TB1=1, TB2=3, and TB3=2, the terminal may select CAPC priority 1, CAPC priority 2, or CAPC priority 3 according to the implementation to determine the number of time slots for multi-continuous time slot transmission.

[0209] Optional embodiment: The terminal determines the number of time slots for multiple consecutive time slot transmissions according to a CAPC associated with a TB.

[0210] For example, if the SL MAC PDU only contains SL MAC CE, the CAPC of the SL MAC PDU is the highest priority (the lowest CAPC value), the terminal determines the number of time slots for multiple consecutive time slot transmissions based on the highest priority CAPC.

[0211] For example, if the SL MAC PDU includes an SCCH SDU, the CAPC of the SL MAC PDU is the highest priority (the lowest CAPC value), the terminal determines the number of time slots for multiple consecutive time slot transmissions based on the highest priority CAPC.

[0212] Exemplarily, if the SL MAC PDU includes a SL MAC SDU, the terminal determines the number of time slots for multiple consecutive time slot transmissions based on the maximum value, minimum value, median value, or average value of the CAPC associated with the LCH multiplexed into the SL MAC PDU.

[0213] Specifically, when submitting this parameter, the terminal has not yet executed the LCP process, that is, has not yet assembled the packet, so the terminal can determine the TB through the cache status of the LCH with data to be sent.

[0214] Optional embodiment: The terminal determines the number of time slots for multiple consecutive time slot transmissions according to the priority associated with one or more TBs.

[0215] Specifically, the priority is the logical channel priority. Specifically, the priority associated with the one or more TBs may be the lowest logical channel priority, the highest logical channel priority, or the average logical channel priority, etc., in the SL LCH and / or SL MAC CE contained in the one or more TBs. Specifically, when submitting this parameter, the terminal has not yet performed the LCP process, that is, the packet has not yet been assembled. Therefore, the one or more TBs may be determined by the terminal through the cache status of the LCH with data to be sent. For example, it is determined by the logical channel priority of the LCH with data to be transmitted.

[0216] Optional embodiment: The terminal determines the number of time slots for multi-continuous time slot transmission according to the remaining PDB or PDB of one or more TBs.

[0217] Specifically, the (remaining) PDB associated with the one or more TBs may be the lowest (remaining) PDB / highest (remaining) PDB / average (remaining) PDB, etc., in the SL LCH and / or SL MAC CE contained in the one or more TBs. Specifically, when submitting this parameter, the terminal has not yet performed the LCP process, that is, no packet has been assembled. Therefore, the one or more TBs may be determined by the terminal based on the cache status of the LCH with data to be sent. For example, it may be determined based on the (remaining) PDB of one or more LCHs with data to be transmitted.

[0218] Optional embodiment: The terminal determines the number of time slots for multi-continuous time slot transmission according to the data buffer size or status (databuffersize) of the data.

[0219] Optionally, the terminal determines the number of time slots for multi-continuous time slot transmission based on the cache size of the data currently to be transmitted. Exemplarily, when the cached data exceeds a preset threshold, the terminal enables MCSt and determines the number of time slots for multi-continuous time slot transmission based on the size of the cached data. The preset threshold can be obtained through configuration or pre-configuration. Exemplarily, a terminal in a connected state can obtain a preset threshold configured by a network device through dedicated signaling. For a terminal in an IDLE state or an INACTIVE state, the network device configures the preset threshold through SIB. For a terminal in an OOC state, the network device configures the preset threshold through pre-configuration. Alternatively, the preset threshold is determined by the terminal implementation.

[0220] Optional embodiment: The terminal determines the number of time slots for multi-continuous time slot transmission based on the measured CBR or the measured RSSI.

[0221] Exemplarily, when the CBR measured by the resource pool exceeds or is less than a preset threshold, the terminal enables MCSt and determines the number of time slots for multiple consecutive time slot transmissions based on the CBR measured by the resource pool. Exemplarily, when the RSSI measured by the resource pool exceeds or is less than a preset threshold, the terminal enables MCSt and determines the number of time slots for multiple consecutive time slot transmissions based on the RSSI measured by the resource pool. The preset threshold can be obtained through configuration or pre-configuration. Exemplarily, a terminal in a connected state can obtain the preset threshold configured by the network device through dedicated signaling. For a terminal in an IDLE state or an INACTIVE state, the network device configures the preset threshold through SIB. For a terminal in an OOC state, the network device configures the preset threshold through pre-configuration. Alternatively, the preset threshold is determined by the terminal.
