The technical solution of the present application is further described in detail below in conjunction with the accompanying drawings. FIG1 is a schematic diagram of a communication system 100 applicable to an embodiment of the present application. As shown in FIG1 , a terminal device 130 can access a wireless network to obtain services of an external network (such as the Internet) through the wireless network, or communicate with other devices through the wireless network, such as communicating with other terminal devices. The wireless network includes a radio access network (RAN) device 110 and / or a core network (CN) device 120, wherein the RAN device 110 is used to access the terminal device 130 to the wireless network, and the CN device 120 is used to manage the terminal device and provide a gateway for communicating with the external network. It should be understood that the number of each device in the communication system 100 shown in Figure 1 is for illustration only, and the embodiments of the present application are not limited to this. In actual applications, the communication system 100 may also include more terminal devices 130, more RAN devices 110, and may also include other devices. It should also be understood that when the terminal device 130 communicates with other terminal devices (such as the terminal device 130'), the technical solutions in the embodiments of the present application are also applicable. FIG2 is a schematic diagram of a network architecture 200 applicable to an embodiment of the present application. As shown in FIG2 , the network architecture 200 includes CN equipment, RAN equipment, and terminal equipment. Among them, the RAN equipment includes a baseband device and a radio frequency device, wherein the baseband device can be implemented by one node or by multiple nodes, and the radio frequency device can be implemented independently from the baseband device, or can be integrated in the baseband device, or some functions can be integrated independently and some functions can be integrated in the baseband device. For example, in an LTE communication system, a RAN device (eNB) includes a baseband device and a radio frequency device, wherein the radio frequency device can be arranged remotely relative to the baseband device, for example, a remote radio unit (RRU) is a remote radio unit arranged relative to a BBU. The communication between RAN equipment and terminal equipment follows a certain protocol layer structure. For example, the control plane protocol layer structure may include the functions of protocol layers such as the radio resource control (RRC) layer, the packet data convergence protocol (PDCP) layer, the radio link control (RLC) layer, the media access control (MAC) layer and the physical layer (PHY); the user plane protocol layer structure may include the functions of protocol layers such as the PDCP layer, the RLC layer, the MAC layer and the physical layer; in a possible implementation, a service data adaptation protocol (SDAP) layer may also be included above the PDCP layer. The RAN device can implement the functions of the protocol layers such as RRC, PDCP, RLC and MAC by one node, or can implement the functions of these protocol layers by multiple nodes. For example, in an evolutionary structure, the RAN device may include a CU and a DU, and multiple DUs may be centrally controlled by one CU. As shown in FIG2 , the CU and the DU may be divided according to the protocol layers of the wireless network, for example, the functions of the PDCP layer and above protocol layers are set in the CU, and the functions of the protocol layers below the PDCP, such as the RLC layer and the MAC layer, are set in the DU. This division of the protocol layer is only an example. It can also be divided in other protocol layers, such as dividing in the RLC layer, setting the functions of the RLC layer and the protocol layers above in the CU, and the functions of the protocol layers below the RLC layer in the DU; or dividing in a certain protocol layer, for example, setting some functions of the RLC layer and the functions of the protocol layers above the RLC layer in the CU, and setting the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer in the DU. In addition, it can also be divided in other ways, such as dividing by latency, setting the functions whose processing time needs to meet the latency requirements in the DU, and the functions that do not need to meet the latency requirements in the CU. In addition, the radio frequency device can be independently integrated and not placed in the DU, or it can be integrated in the DU, or partly remotely located and partly integrated in the DU, without any limitation here. FIG3 is a schematic diagram of a network architecture 300 applicable to an embodiment of the present application. Compared with the network architecture shown in FIG2 , FIG3 may also separate the control plane (CP) and the user plane (UP) of the CU and implement them in different entities, namely, a control plane CU entity (i.e., a CU-CP entity) and a user plane CU entity (i.e., a CU-UP entity). In the above network architecture, the signaling generated by the CU can be sent to the terminal device through the DU, or the signaling generated by the terminal device can be sent to the CU through the DU. The DU can directly encapsulate the signaling through the protocol layer and transparently transmit it to the terminal device or CU without parsing it. In the following embodiments, if the transmission of such signaling between the DU and the terminal device is involved, at this time, the sending or receiving of the signaling by the DU includes this scenario. For example, the signaling of the RRC or PDCP layer will eventually be processed as the signaling of the PHY layer and sent to the terminal device, or it will be converted from the received signaling of the PHY layer. Under this architecture, the signaling of the RRC or PDCP layer can also be considered to be sent by the DU, or sent by the DU and the RF loader. The network architecture shown in FIG. 1 , FIG. 2 or FIG. 3 above may be applicable to various radio access technologies (RAT) The communication system may be, for example, an LTE communication system, or a 5G (or new radio (NR)) communication system, or a transition system between an LTE communication system and a 5G communication system, and the transition system may also be called a 4.5G communication system, and of course, it may also be a future communication system. The network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. It is known to those skilled in the art that with the evolution of the communication network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems. For example, the present application may be applicable to vehicle to everything (V2X) scenarios. It should be understood that the network architecture shown in Figures 1 to 3 above is only an example of the present application and does not have any limiting effect on the embodiments of the present application. In particular, the embodiments of the present application can also be applied to other network architectures, for example, without distinguishing between base stations and core networks, that is, base stations and core networks can belong to the same network device, and the communication between the network device and the terminal device; or, the communication between terminal devices, etc. To facilitate understanding, the following terms related to the embodiments of the present application are first introduced. 1. Extended reality (XR) XR can refer to various environments that combine reality and virtuality, as well as human-machine interactions, generated by computing technologies and wearable devices. It mainly includes virtual reality (VR), augmented reality (AR), and mixed reality (MR) and other virtual-reality interaction technologies. In order to enhance the experience of human interaction with the virtual world, XR services have strict requirements on bandwidth and latency. For example, XR can include cloud gaming. For example, during downlink transmission, the server's encoder generates data content at a fixed frequency (e.g., 60 Hz or 120 Hz, etc.) and transmits it to the XR terminal via the core network and RAN. For example, during uplink transmission, the XR terminal can collect images through the built-in camera and continuously upload images of the current scene to the server at a specific frequency (e.g., 60 Hz or 120 Hz, etc.). For example, XR services usually generate data periodically at a certain frame rate. For example, the business model for downlink XR services is roughly: AR / VR and cloud gaming. Among them, the AR / VR frame rate can be 60fps, that is, 60 frames of video images are generated per second, and one video frame appears approximately every 16.66ms. The AR / VR frame rate can also be 120fps, that is, 120 frames of video images are generated per second, and one video frame appears approximately every 8.33ms. The cloud gaming frame rate can be 60fps or 120fps, that is, 60 frames of video images are generated per second or 120 frames of video images per second. For example, the latency requirement of XR services may be 10ms, 30ms, etc. Optionally, in an actual transmission system, data jitter may occur due to data encoding delay, network transmission delay, etc. For example, jitter may be considered to obey a truncated Gaussian distribution, with the truncation range being approximately [-4, 4] ms. For example, the jitter may include uplink jitter and / or downlink jitter. For example, for XR video services, images can be encoded in a group of pictures (GOP) encoding mode and / or a slice encoding mode during encoding. For example, for the slice encoding mode, a video frame may include an I slice and one or more P slices. For example, for the GOP encoding mode, a GOP may include an I frame, or a GOP includes an I frame and one or more P frames. Optionally, the GOP may also include B frames. Exemplarily, an I frame is an intra-coded frame (also referred to as an intra-coded frame, a key frame, an important frame, etc.), and an I frame is a reference frame for a P frame and / or a B frame, and has the characteristics of independent encoding and decoding. Exemplarily, a P frame is a forward prediction frame (also referred to as a forward prediction coded frame, a forward reference frame, a dependent frame, a non-key frame, etc.). When decoding a P frame, it is necessary to refer to the most recent I frame or P frame in front, and a P frame can be a reference frame for a subsequent P frame and / or B frame. Exemplarily, a B frame is a bi-directional interpolated prediction frame, which may also be called a dependent frame, a non-key frame, etc. When decoding a B frame, it is necessary to refer to the most recent I frame or P frame in the front, as well as the most recent P frame in the back. Exemplarily, an I frame is a complete picture, and a P frame records the changes relative to the I frame. Without an I frame, the P frame cannot be decoded, so the transmission priority of the I frame must be higher than that of the P frame. If an I frame fails to be transmitted during the transmission process (for example, it has not been successfully transmitted even if its delay requirement is met), even if the subsequent video frame that depends on the I frame (for example, a P frame) is transmitted successfully, correct decoding cannot be achieved on the receiving side. Fig. 4 is a schematic diagram of the structure of a GOP 400 provided in an embodiment of the present application. As shown in Fig. 4, a GOP sequence (eg, GOP#1 or GOP#2) includes an I frame and multiple P frames. Exemplarily, a data burst may also be referred to as a data burst, which is a group of protocol data units (PDUs) generated and sent by an application in a short period of time (e.g., A set of data multiple PDUs generated and sent by the application in a short period of time). For example, a PDU Set may include one or more PDUs carrying the payload of one unit of information generated at the application level (eg, a frame or video slice for XRM Services, as used in TR 26.926).

[0027] )). For example, a PDU set includes a frame or a slice. For example, a PDU set includes a frame or a slice. For example, in some implementations, the application layer needs all PDUs in a PDU Set to use the corresponding unit of information. In other implementations, the application layer can still recover parts all or of the information unit, when some PDUs are missing. Optionally, a data burst includes at least one PDU set. For example, data burst 1 may be associated with one or more data bursts, which need to depend on data burst 1. If data burst 1 is discarded, the one or more data bursts may not be decoded. For example, PDU set 1 may be associated with one or more PDU sets, which need to depend on PDU set 1. If PDU set 1 is discarded, the one or more PDU sets may not be decoded. For example, the XR service may be a periodic arrival service. For example, the XR service may be a periodic arrival service with jitter. For example, the XR service requires low latency and low power consumption. For example, the period of the XR service is a non-integer. Among them, the period of the XR service is calculated based on the frame generation rate X (unit: fps). The period of the XR service is the inverse of the frame generation rate X. Typical values ​​of the frame generation rate X are 30fps, 60fps, 90fps, and 120fps. So the periods of the XR services are: 30fps: (1 / 30fps)s=(1 / 30fps)×1000ms=1000 / 30ms=100 / 3ms≈33.3333ms 60fps: (1 / 60fps)s=(1 / 60fps)×1000ms=1000 / 60ms=50 / 3ms≈16.6667ms 90fps: (1 / 90fps)s=(1 / 90fps)×1000ms=1000 / 90ms=100 / 9ms≈11.1111ms 120fps: (1 / 120fps)s=(1 / 120fps)×1000ms=1000 / 120ms=25 / 3ms≈8.3333ms Optionally, the XR service has a very short latency requirement, for example, the uplink (UL) is 30 ms. For example, all data of a data burst may not be delivered from the APP side of the terminal device to the access stratum (AS) of the terminal device at the same time. It may take a certain amount of time, for example, 3ms or 5ms, to deliver all data from the APP side of the terminal device to the AS layer of the terminal device. This can be called the delay spread of the data burst. Optionally, for XR services, the data volumes of different data bursts may be different. For example, the data volume of an I frame may be greater than the data volume of a P frame. 2. NR protocol architecture The NR protocol architecture involved in the embodiment of the present application can be divided into a user plane protocol stack and a control plane protocol stack. The above two protocol stacks will be described in detail below in conjunction with Figure 5. Figure 5 is a schematic diagram of a protocol stack 500 provided in an embodiment of the present application. (a) in Figure 5 shows a user plane protocol stack, and (b) in Figure 5 shows a control plane protocol stack. User plane protocol stack: a protocol cluster used for user data transmission. As shown in FIG5(a), the user plane protocol stack may include five layers: PHY layer, MAC layer, RLC layer, PDCP layer and SDAP layer. Control plane protocol stack architecture: that is, the protocol cluster used for the control signaling transmission of the system. As shown in (b) of Figure 5, the control plane protocol stack may include non-access-stratum (NAS), RRC, PDCP, RLC, MAC, and PHY layers. For example, the PHY layer may be responsible for processing one or more of encoding and decoding, modulation and demodulation, multi-antenna mapping, and other physical layer functions. For example, the MAC layer may be responsible for one or more of hybrid automatic repeat request (HARQ), uplink scheduling, downlink scheduling, etc. For example, the RLC layer may be responsible for one or more of segmentation, reassembly, and retransmission processing. For example, the PDCP layer may be responsible for one or more of header compression / decompression, security (encryption function, integrity protection function), retransmission, and in-order delivery. For example, the RRC layer may be responsible for one or more of broadcasting, paging, RRC connection management, radio bearer control, mobility management, terminal device measurement reporting and control. For example, the NAS layer may be responsible for one or more of identity authentication, mobility management, security control, etc. For example, the terminal device may communicate with the access and mobility management function (AMF) network element on the core network side through the NAS layer. For the user plane protocol stack, the NR protocol stack has an additional SDAP layer compared to the LTE protocol stack. For the control plane protocol stack, the NR protocol stack is similar to the LTE protocol stack. Optionally, in the embodiment of the present application, each layer in the protocol stack may also be replaced by an entity. For example, the PDCP layer may be replaced by a PDCP entity, and the SDAP layer may be replaced by an SDAP entity. A unified description is made here, and no further description is given later. 3. Introduction to time units in NR In a communication system, time domain resources include: radio frames (also called system frames, or frames for short), subframes, time slots, and symbols (for example, orthogonal frequency division multiplexing (OFDM) symbols). Among them, the duration of a frame is 10ms, and each frame can have a system frame number (SFN) (also referred to as a frame index). Exemplarily, the range of SFN is 0 to 1023, so the frame period is 1024×10ms=10240ms. In the 5G NR system, a group of frames with SFN of 0 to 1023 is called a superframe (e.g., hyper system frame, or, hyper frame), that is, a superframe is equal to 1024 frames, which is equal to 10240ms. For example, each superframe can have a hyper frame number (H-SFN). In addition, a frame contains 10 subframes, and the duration of each subframe is 1ms. A subframe can contain one or more time slots. It should be noted that when the sub-carrier space (SCS) is different, the number of time slots contained in each frame is different, the number of time slots contained in each subframe is different, and the duration of each time slot is also different. The details are shown in Table 1. in, is the number of symbols contained in a time slot, is the number of time slots contained in a frame, is the number of time slots contained in a subframe, Δf = 2 μ ·15 represents the subcarrier spacing, in kHz. Optionally, μ represents an index corresponding to the subcarrier spacing, which is used to indicate a subcarrier spacing. Table 1 4. Configured grant (CG) For example, uplink resources may include dynamic grant (DG) and CG. For example, DG is a resource that a network device dynamically schedules to a terminal device through downlink control information (DCI). In the uplink, a network device can dynamically allocate resources to a terminal device on a physical downlink control channel (PDCCH) (e.g., through a cell-radio network temporary identifier (C-RNTI) or a configured scheduling-radio network temporary identity (CS-RNTI)). For example, when its downlink reception is enabled (e.g., when discontinuous reception (DRX) is configured, this behavior is controlled by DRX), the terminal device monitors PDCCH to find possible uplink resources for uplink transmission. For example, a CG is a resource that a network device configures for a terminal device. For example, a CG may include a type 1 CG and a type 2 CG. For example, for type 1CG, the network device can directly provide the configured uplink authorization (for example, which can be a periodic resource) to the terminal device through RRC signaling. For example, for type 1CG, the network device can indicate any one or more of the following CG-related items to the terminal device through RRC signaling: time reference frame (timeReferenceSFN), time domain offset (timeDomainOffset), periodicity (periodicity), time domain resource allocation (timeDomainAllocation). For example, timeDomainAllocation can indicate the starting symbol S and length L, and PUSCH mapping type. For example, S is the starting symbol, and L is the number of symbols occupied by an uplink resource. For example, for type 2CG, the network device can configure the CG period for the terminal device through RRC signaling, and then activate the configured uplink authorization through the CS-RNTI encrypted PDCCH. For example, the network device may indicate the periodicity of the CG to the terminal device via RRC signaling. For example, the network device activates the type 2 CG through DCI, and the terminal device can determine the SFN start time 、slot start time and symbolstart time , as well as S and L. For example, SFN start time 、slot start time and symbol start time They are respectively the SFN, slot and symbol of the first transmission opportunity of the physical uplink shared channel (PUSCH) where the configured uplink grant is initialized or reinitialized (or, the starting SFN, the starting slot and the starting symbol). Optionally, CG resources are periodic and suitable for periodic services, so that the network device does not need to schedule uplink resources for the terminal device through DCI every time. Figure 6 is a schematic diagram of the CG provided in an embodiment of the present application. For example, a CG may be as shown in Figure 6 (a), and a CG cycle includes a CG opportunity. For example, a square is a CG opportunity. For example, a CG may be as shown in Figure 6 (b), and a CG cycle includes multiple CG opportunities. 5. CG occasion For example, the CG opportunity may be a resource unit. For example, a resource unit may include resources represented in the time domain and the frequency domain. For example, the CG opportunity may be a PUSCH resource. For example, the CG opportunity may be a configured uplink grant. For example, a CG opportunity may be a PUSCH resource. For example, a CG opportunity may be a configured uplink grant. For example, the CG opportunity may be used for the terminal device to send uplink information. For example, the uplink information may include uplink data and / or uplink signaling. For example, the uplink signaling may include at least one of the following: signaling of the physical layer, control information of the medium access control (MAC) layer (e.g., MAC CE), control information of the RLC layer (e.g., control PDU), control information of the PDCP layer (e.g., control PDU), control information of the SDAP layer (e.g., control PDU), signaling of the RRC layer, and signaling of the NAS layer. 6. Calculation formula of CG occasion For example, for type 1CG, the Nth CG opportunity is located at (or occurs at) symbol (or, SFN, slot, symbol) calculated according to the following formula: [(SFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot) +(slot number in the frame×numberOfSymbolsPerSlot)+symbol number in the slot]= (timeReferenceSFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot +timeDomainOffset×numberOfSymbolsPerSlot+S+N×periodicity) modulo(1024×numberOfSlotsPerFrame×numberOfSymbolsPerSlot) For example, N≥0. For example, numberOfSlotsPerFrame indicates the number of time slots contained in a frame. For example, numberOfSymbolsPerSlot indicates the number of symbols contained in a time slot. For example, slot number in the frame indicates an index of a time slot, or an index of a time slot in a frame (or a frame corresponding to a SFN). For example, in an embodiment of the present application, the index may include / be replaced by: number, or, number. For example, symbol number in the slot represents the index of a symbol or the index of a symbol in a time slot (or, the time slot corresponding to slot number in the frame). For example, timeReferenceSFN indicates a SFN used to determine the offset of a resource in the time domain. For example, timeReferenceSFN may be 0 or 512. For example, timeDomainOffset indicates the offset of the resource in the time domain relative to SFN=timeReferenceSFN. For example, the unit of timeDomainOffset is slot. For example, S represents the index of the starting symbol. For example, periodicity represents the period of CG. For example, the unit of periodicity is symbol. For example, for type 2CG, the Nth CG opportunity is located at (or occurs at) symbol (or, SFN, slot, symbol) calculated according to the following formula: [(SFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot) +(slot number in the frame×numberOfSymbolsPerSlot)+symbol number in the slot]= [(SFN start time ×numberOfSlotsPerFrame×numberOfSymbolsPerSlot +slot start time ×numberOfSymbolsPerSlot+symbol start time )+N×periodicity] modulo(1024×numberOfSlotsPerFrame×numberOfSymbolsPerSlot) For example, SFN start time Indicates the starting SFN, or the first PUSCH for which the configured uplink grant is initialized or reinitialized The SFN of the transmission opportunity (or, the starting SFN). For example, slot start time Indicates the starting slot, or the slot and symbol (or the starting slot) of the first transmission opportunity of the PUSCH where the configured uplink grant is initialized or reinitialized. For example, symbol start time Indicates the starting symbol, or the symbol of the first transmission opportunity (or the starting symbol) of the PUSCH for which the configured uplink grant is initialized or reinitialized. It should be noted that the above formula calculation can be performed by the network device, or by the terminal device, or by both the network device and the terminal device. Exemplarily, the location of CGoccasion can be calculated by the MAC entity of the network device, or by the MAC entity of the terminal device. It should be understood that the embodiments of the present application are not limited to this. 6. Calculation of the hybrid automatic repeat request process ID (HARQ process ID) at the CG timing For DG, the network device indicates the HARQ process ID corresponding to the DG resource to the terminal device in the DCI that schedules the DG resource. For CG, the terminal device can calculate the HARQ process ID corresponding to the CG opportunity using the following formula. For example, for an uplink grant that is neither configured with harq-procID-offset2 nor with cg-retransmission timer, the HARQ process ID associated with the first symbol of an uplink (UL) transmission (or, a CG opportunity) can be obtained by the following formula: HARQ process ID=[floor(CURRENT_symbol / periodicity)]modulo nrofHARQ-Processes For example, for an uplink grant configured with harq-procID-offset2, the HARQ process ID associated with the first symbol of the UL transmission (or, a CG opportunity) can be obtained by the following formula: HARQ process ID=[floor(CURRENT_symbol / periodicity)]modulo nrofHARQ-Processes+hard-procID-offset2 For example, CURRENT_symbol can be obtained by the following formula: CURRENT_symbol=(SFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot+slot number in the frame×numberOfSymbolsPerSlot+symbol number in the slot) Optionally, in the case of a bundle, CURRENT_symbol refers to the symbol index of the first transmission opportunity (or, the first CG opportunity) of a repetition bundle. For example, nrofHARQ-Processes: the number of HARQ process IDs corresponding to a CG (or a set of CGs, or a CG configuration, or a set of CG configurations). For example, harq-procID-offset2: offset of HARQ process ID. For example, harq-procID-offset2 can be used to distinguish HARQ process IDs of different CGs. For example, the effect of rounding (floor) is that the distance / interval between the CG opportunity and SFN=0, slot=0, symbol=0 may not be an integer multiple of the CG period. In order to eliminate the influence, rounding can be adopted. For example, for a CG (or a set of CGs), once its related configuration is determined, the HARQ process ID of its CG timing is also determined. Exemplarily, for one CG (or, a set of CGs), the calculation results of the HARQ process ID are shown in Table 2. Table 2 Exemplarily, a CG can be as shown in Figure 7, where a CG period includes a CG opportunity, where the SCS is 15kHz, the periodicity is 14symbol, the nrofHARQ-Processes is 16, and the period from symbol 4 of subframe 1 to symbol 3 of subframe 2 is a CG period. For example, a CG may also be as shown in FIG8 , where a CG cycle includes multiple CG opportunities, wherein the SCS is 15 kHz, The periodicity is 28symbol, the nrofHARQ-Processes is 16, and the period from symbol 4 of subframe 1 to symbol 3 of subframe 3 is a CG period. Optionally, as shown in Figure 8, multiple CG opportunities (or all CG opportunities) in a CG cycle can correspond to the same HARQ process ID, that is, multiple CG opportunities (or all CG opportunities) in a CG cycle can be used to transmit the same MAC layer protocol data unit (MAC Protocol Data Unit, MAC PDU). 7. Configured grant timer (CGT) For example, the value of CGT is configured for each CG. For example, the value of CGT is configured according to an integer multiple of the CG period, and the minimum value of CGT is 1 times the CG period. For example, the operation of CGT is maintained for each HARQ process. For example, during the operation of the CGT corresponding to a HARQ process, new transmission / transmission cannot be performed on the CG resources (or CG timing) associated with the HARQ process. For example, during the operation of the CGT corresponding to a HARQ process, the CG resources associated with the HARQ process will not be delivered to the HARQ entity. For example, the purpose of CGT is to prevent the subsequent CG from flushing out the data on the previous DG / CG, so that the data on the previous DG / CG can be retransmitted. For example, for UL, the number of HARQ processes supported by the terminal device is: 16, or, 32. For example, for nrofHARQ-Processes HARQ processes corresponding to a CG, if the CGT of a HARQ process is running, new transmission / transmission cannot be performed on the CG resources corresponding to the HARQ process. For example, for each HARQ process in nrofHARQ-Processes HARQ processes corresponding to a CG, the conditions for starting or restarting the CGT corresponding to a HARQ process may include any one or more of the following: (1) receiving the DCI scrambled by the C-RNTI corresponding to the HARQ process, and the DCI is used to schedule uplink resources / grants; (2) receiving a DCI scrambled by the CS-RNTI corresponding to the HARQ process, and the DCI is used to schedule uplink resources / grants, and the value of the new data indicator (NDI) contained in the DCI is 1; (3) For the resources corresponding to the HARQ process (eg, CG resources or DG resources), the MAC PDU to be transmitted has been obtained. For example, "the DCI is used to schedule uplink resources / authorization, and the value of NDI contained in the DCI is 1" may include / be replaced by: the DCI is used to schedule the retransmission resources of the CG. For example, data to be transmitted has been obtained and may include / be replaced by: the transmission has been performed. For example, for each of the nrofHARQ-Processes processes corresponding to a CG, the condition for stopping the CGT corresponding to a HARQ process is as follows: receiving the CS-RNTI-encrypted DCI corresponding to the HARQ process, and the DCI is used to schedule uplink resources / authorization, and the value of the NDI contained in the DCI is 0. For example, "the DCI is used to schedule uplink resources / authorization, and the value of NDI contained in the DCI is 0" may include / be replaced by: the DCI is used to activate the CG. 8. R18 XR For example, CG resources can also be applied to XR services. However, since the amount of data in each data burst of XR services is uncertain, for XR services, the network device can configure a CG containing multiple CG opportunities in a CG cycle for the terminal device, and multiple CG opportunities in a CG cycle can correspond to different HARQ process IDs. For example, different CG opportunities in a CG cycle can be used to transmit different MAC PDUs. For example, for the CG related to the XR service, the network device can configure the number of time slots contained in a CG cycle for the terminal device. For example, it has been agreed that the maximum number of time slots is 16 or 32, depending on the capabilities of the terminal device, and the minimum number of time slots is 2. For example, for a CG, the number of time slots is 16, which means that a CG cycle contains 16 CG opportunities (or, configured CG opportunities), or, it means that a CG cycle contains at most 16 CG opportunities (or, valid CG opportunities). For example, a time slot contains 1 CG opportunity (or, configured CG opportunity), or, a time slot contains at most 1 CG opportunity (or, valid CG opportunity). For example, some time domain positions may be downlink time domain positions, and the CG opportunities (or, configured CG opportunities) in these time domain positions can be regarded as invalid. For example, the number of time slots may include / be replaced by: the number of consecutive time slots. For example, for the CG related to the XR service, the terminal device can calculate the HARQ process ID corresponding to the CG opportunity by the following formula. For example, for an uplink grant that is neither configured with harq-procID-offset2 nor with cg-retransmission timer, the HARQ process ID associated with the first symbol of an uplink (UL) transmission (or, a CG opportunity) can be obtained by the following formula: HARQ Process ID=[numberOfPUSCH-PerPeriod×floor(CURRENT_symbol / periodicity)+ ID_OFFSET]modulo nrofHARQ-Processes For example, for an uplink grant configured with harq-procID-offset2, the HARQ process ID associated with the first symbol of the UL transmission (or, a CG opportunity) can be obtained by the following formula: HARQ Process ID=[numberOfPUSCH-PerPeriod×floor(CURRENT_symbol / periodicity)+ ID_OFFSET]modulo nrofHARQ-Processes+harq-ProcID-Offset2 For example, for the first configured CG opportunity within a CG cycle, ID_OFFSET is equal to 0. For example, for the Kth valid CG opportunity after the first configured CG opportunity in the same / one CG cycle, ID_OOFFSET is equal to K. For example, K≥1. Optionally, the configuration of the CG may match the XR service, for example, one CG cycle may correspond to one data burst. Optionally, in order to match CG and XR services, there are two ways: Mode 1: CG supports non-integer periods. For example, the period of CG is equal to the period of XR service. For example, a set of CG is configured to match the XR service with a period of 50 / 3 milliseconds, where the period of the CG is 50 / 3 milliseconds. Method 2: Configure multiple (or multiple) CGs, and the period of each CG is an integer. For example, configure 3 CGs to match XR services with a period of 50 / 3 milliseconds, where the period of the 3 CGs is 50 milliseconds. For example, configure 9 CGs to match XR services with a period of 100 / 9 milliseconds, where the period of the 9 CGs is 100 milliseconds. For method 1 and / or method 2, there may be a problem that some CG opportunities (or CG opportunities within certain CG cycles) are unavailable (or all are unavailable). The details are as follows: For method 1, for a CG, the configured CG period is a non-integer, the actual CG timing / CG period is not periodic, or the intervals between the actual CG periods are not the same, or the intervals between the actual CG periods are not equal to the configured CG period. Exemplarily, Table 3 lists the intervals between the configured CG periods and the actual CG periods corresponding to different frame rates. If CGT is still configured using multiples of the CG period, some CG timings (or CG timings within certain CG periods) may be unavailable (or all unavailable). Table 3 For example, if the configured CG period is 50 / 3ms, the actual interval between CG periods is 17 / 17 / 16ms, CGT is 1 times the configured CG period = 50 / 3ms = 16.67ms, the number of slots is 4, and nrofHARQ-Processes is 4. For example, one CG period may cycle through a round of HARQ process IDs (including HARQ process 0, HARQ process 1, HARQ process 2, and HARQ process 3), as shown in FIG9 . Since the duration of CGT is 16.67ms, for the next CG period of a CG period of 16ms, the CG timing corresponding to HARQ process 0 will be unavailable due to the running of the CGT of the HARQ process 0, the CG timing corresponding to HARQ process 1 will be unavailable due to the running of the CGT of the HARQ process 1, and so on. Therefore, in this case, the CG timing in the next CG period of a CG period of 16ms will be unavailable due to the running of the CGT. For method 1, if CGT is still configured as an integer multiple of the CG cycle, it may cause all CG opportunities in certain CG cycles to be unavailable, thus making the CG unable to match the XR service. For method 2, for UL, if the terminal device supports 16 HARQ processes, at least 2 slots will be configured for each CG. If at least two HARQ processes are configured for each CG, 9 sets of CGs need to be configured for 100 / 9ms XR services. In the existing authorization scenario, the HARQ process IDs of different CGs are not shared, and 9×2=18 HARQ processes are required. It is not enough. If the number of HARQ processes supported by the terminal device is not considered to be increased, then different CGs need to share the HARQ process ID. In the case of different CGs sharing the HARQ process, if the CGT is still configured as a minimum of 1 times the CG period, some CG opportunities (or CG opportunities within certain CG periods) may be unavailable (or all unavailable). For example, if three sets of CGs are configured, for the three sets of CGs, the configured CG period is 50ms, for each CG, the number of slots is 4, and nrofHARQ-Processes is 4. For example, for a CG, a CG period may cycle a round of HARQ process ID. Among them, the first set of CGs and the third set of CGs share the HARQ process, as shown in Figure 10, if CGT is 1 times the configured CG period = 50ms, in the third set of CGs, the CG timing corresponding to HARQ process 0 will be unavailable due to the CGT of the HARQ process 0 (started by the HARQ process 0 of the first set of CGs) running, and the CG timing corresponding to HARQ process 1 will be unavailable due to the CGT of the HARQ process 1 (started by the HARQ process 1 of the first set of CGs) running, and so on. Therefore, in this case, some CG timings in the third set of CGs (or, CG timings in certain CG periods) are unavailable (or, all are unavailable). For mode 2, if different CGs share the HARQ process, it may cause all CG opportunities in certain CG cycles to be unavailable, thus making it impossible for the CG to match the XR service. In view of this, the embodiments of the present application propose a communication method and a communication device, which are conducive to avoiding the problem of unavailable CG opportunities in certain CG cycles, and further conducive to improving the resource utilization of the system, improving the system capacity, and reducing data transmission delay, thereby improving the user experience. The communication method and communication device provided by the present application will be described in detail below in conjunction with the accompanying drawings. It should be understood that the technical solution of the present application can be applied to a wireless communication system, for example, the communication system 100 shown in FIG1. ​​Below, without loss of generality, the communication method provided by the embodiment of the present application is described in detail by taking the terminal device as the execution subject as an example. It should be understood that the terminal device in the embodiment of the present application can be replaced by other devices, and the network device can also be replaced by other devices, and the embodiment of the present application does not make specific limitations on this. FIG11 shows a schematic flow chart of a communication method 700 provided in an embodiment of the present application. The method 1100 includes: Optionally, S1110, the terminal device obtains configuration information of the first CG. For example, the terminal device obtains the configuration information of the first CG may include / be replaced by: the terminal device receives the configuration information of the first CG. For example, accordingly, the network device sends the configuration information of the first CG to the terminal device. For example, the configuration information of the first CG may include information of the period of the first CG. Optionally, the period of the first CG is a non-integer or fraction. Optionally, the period of the first CG is a rational number. For example, the period of the first CG is 50 / 3ms or 25 / 3ms or 100 / 3ms or 100 / 9ms. Optionally, the period of the first CG is an integer. For example, the period of the first CG is 50ms, 25ms, or 100ms. Optionally, the first CG is associated with the XR service. Optionally, the first CG is associated with the XR service and may include / be replaced by: the first CG / first CG timing satisfies the LCP mapping restriction of the XR-related LCH. Optionally, the configuration information of the first CG may include other information in addition to the period information of the first CG. Optionally, for different CG types, such as type1 CG and type2 CG, the configuration information of the first CG may be different or the same. For example, the configuration information of the first CG corresponding to different CG types can be referred to in the previous text. For the sake of simplicity, it will not be repeated here. In addition, the configuration information of the first CG may also be different from the previous text, and this application does not impose any restrictions on this. Optionally, S1120, the terminal device determines information of the first CG opportunity. Optionally, the terminal device determines information of the first CG opportunity based on configuration information of the first CG. Optionally, the information of the first CG opportunity includes information of the frame, time slot and symbol of the first CG opportunity. Optionally, S1130, the terminal device determines whether the first condition is met. S1140: If the first condition is met, the terminal device regards the first CGT as not running, or the terminal device stops the first CGT, or the terminal device regards the first CG opportunity as available for transmission. Optionally, the first CG opportunity is associated with the XR service. For example, the first CG opportunity is associated with the first HARQ process or the first HARQ process ID. For example, the first condition may include: the operation, startup or restart of the first CGT is due to the second CG opportunity. For example, the first CGT is associated with the first HARQ process or the first HARQ process ID. For example, the second CG opportunity is before the first CG opportunity. For example, the second CG opportunity is associated with the first HARQ process or the first HARQ process ID. Optionally, the second CG opportunity is associated with the XR service. For example, the operation, start or restart of the first CGT is caused by the second CG opportunity, and may include / replace any one or more of the following: the operation, start or restart of the first CGT is not caused by the DG and / or the DCI scheduling the DG, or, the previous resource associated with the first HARQ process is the second CG opportunity (or, CG resource), or, the previous resource associated with the first HARQ process is not a DG resource. For example, the second CG opportunity may include / be replaced by CG resources. Optionally, satisfying the first condition may include / be replaced by: satisfying the first condition for the first CG opportunity. Optionally, satisfying the first condition may include / be replaced by: satisfying the first condition and the second condition, or, for the first CG opportunity, satisfying the first condition and the second condition. For example, the second condition may include: for the first CG opportunity, the first CGT is running. For example, the second condition may include: the first CGT is running. Optionally, “for the first CG opportunity, the first CGT is running” may include / be replaced by: at the time domain position of the first CG opportunity, or at the first time before the time domain position of the first CG opportunity, the first CGT is running. For example, the time domain position of the first CG opportunity may include / be replaced by: the starting position of the first CG opportunity. For example, the interval between the first time and the time domain position of the first CG opportunity is the first duration. For example, the first duration may be configured by the network device to the terminal device, may be pre-configured by the protocol, may be determined by the terminal device itself, or may be determined by other means, and this application does not limit this. Optionally, the first CG opportunity and the second CG opportunity do not belong to the same CG cycle. Figure 12 shows a possible scenario, where the first CG opportunity is associated with HARQ process 0, and the second CG opportunity is also associated with HARQ process 0. The second CG opportunity and the first CG opportunity are in different CG cycles. For the first CG opportunity, the first CGT is running, and the operation of the first CGT is caused by the second CG opportunity. Then the terminal device can stop the first CGT to ensure that the first CG opportunity can be used to transmit data. Figure 13 shows another possible scenario, where the first CG opportunity is associated with HARQ process 0, and the second CG opportunity is also associated with HARQ process 0. The second CG opportunity and the first CG opportunity are in the same CG cycle. For the first CG opportunity, the first CGT is running, and the operation of the first CGT is caused by the second CG opportunity. Then the terminal device can stop the first CGT to ensure that the first CG opportunity can be used to transmit data. For example, in the scenario shown in Figure 13, the second CG opportunity and the first CG opportunity are in the same CG cycle, and the network device needs to schedule retransmission within the interval of the same HARQ process. For example, between the HARQ process 0 associated with the second CG opportunity and the HARQ process 0 associated with the first CG opportunity, the HARQ process 0 associated with the second CG opportunity is retransmitted. This method leaves a relatively short processing time for the network device. Optionally, the first CG opportunity and the second CG opportunity do not belong to the same CG. For example, the first CG opportunity and the second CG opportunity do not belong to the same CG, which can be understood as: multiple CGs are configured (for example, method 2), and the first CG opportunity and the second CG opportunity do not belong to the same CG; or, the first CG opportunity and the second CG opportunity are not associated with the same CG / CG configuration. For example, considering the first CG opportunity as available for transmission may include: delivering the first CG opportunity to the HARQ entity (or, the HARQ entity of the terminal device). For example, the terminal device considers the first CG opportunity as available for transmission, which may include: the terminal device (or, the MAC entity of the terminal device) submits the first CG opportunity to the HARQ entity (or, the HARQ entity of the terminal device). Optionally, the above method 1100 also includes: for the first CG opportunity, the first condition is not met, the terminal device does not regard the first CGT as not running, or the terminal device does not stop the first CGT, or the terminal device does not regard the first CG opportunity as available for transmission. For example, not considering the first CG opportunity as available for transmission may include: considering the first CG opportunity as unavailable for transmission, or not delivering the first CG opportunity to the HARQ entity (or, the HARQ entity of the terminal device). For example, the terminal device does not consider the first CG opportunity as available for transmission, which may include: the terminal device (or, the MAC entity of the terminal device) does not deliver the first CG opportunity to the HARQ entity (or, the HARQ entity of the terminal device). Optionally, not satisfying the first condition may include / be replaced by: not satisfying the first condition, and satisfying the second condition. Optionally, the above method 1100 also includes: for the first CG opportunity, the first condition is met, the network device regards the first CGT as not running, or the network device stops the first CGT, or the network device regards the first CG opportunity as available for transmission. For example, the network device considers the first CG opportunity available for transmission, which may include: the network device may receive data at the first CG opportunity. For example, receiving data may include / be replaced by: executing receiving, or, performing receiving. Optionally, the above method 1100 also includes: for the first CG opportunity, the first condition is not met, the network device does not regard the first CGT as not running, or the network device does not stop the first CGT, or the network device does not regard the first CG opportunity as available for transmission. For example, the network device does not consider the first CG opportunity as available for transmission, which may include: the network device does not receive data on the first CG opportunity. For example, if the first CGT is running, the first CG opportunity will be unavailable because the first CGT is still running. Therefore, in an embodiment of the present application, the terminal device regards the first CGT as not running, or stops the first CGT, or regards the first CG opportunity as available for transmission. This is conducive to avoiding the problem of unavailable CG opportunities in certain CG cycles, and is conducive to improving the resource utilization of the system, improving the system capacity, reducing data transmission delay, and improving user experience. In order to solve the problem of unavailability of some CG opportunities in method 1, the present application also provides a communication method, in which the duration of CGT is no longer equal to an integer multiple of the CG cycle, but is slightly smaller than an integer multiple of the CG cycle. This is helpful in avoiding the problem of unavailability of CG opportunities in certain CG cycles, and further helps to improve the resource utilization of the system, improve the system capacity, reduce data transmission delay, and improve user experience. FIG14 shows a schematic flow chart of another communication method 1400 provided in an embodiment of the present application. The method 1400 includes: S1410, the terminal device obtains the configuration information of the first CG. For example, the terminal device obtains the configuration information of the first CG may include / be replaced by: the terminal device receives the configuration information of the first CG. For example, accordingly, the network device sends the configuration information of the first CG to the terminal device. For example, the configuration information of the first CG may include information of the period of the first CG. Optionally, the period of the first CG is a non-integer or fraction. Optionally, the period of the first CG is a rational number. For example, the period of the first CG is 50 / 3ms or 25 / 3ms or 100 / 3ms or 100 / 9ms. Optionally, the first CG is associated with the XR service. Optionally, the first CG is associated with the XR service and may include / be replaced by: the first CG / first CG timing satisfies the LCP mapping restriction of the XR-related LCH. Optionally, the configuration information of the first CG may include other information in addition to the period information of the first CG. Optionally, for different CG types, such as type1 CG and type2 CG, the configuration information of the first CG may be different or the same. For example, the configuration information of the first CG corresponding to different CG types can be referred to in the previous text. For the sake of simplicity, it will not be repeated here. In addition, the configuration information of the first CG may also be different from the previous text, which is not limited by this application. S1420, the terminal device determines the duration of the CGT of the first CG based on the configuration information of the first CG, wherein the duration of the CGT of the first CG is less than (the period of the first CG × K). For example, the duration of the CGT of the first CG may include / be replaced by: the duration of the CGT associated with the first CG. For example, K is greater than zero. For example, K can be understood as the coefficient of CGT. Optionally, the duration of the CGT of the first CG is associated with the period of the first CG, K and a first rounding operation. For example, the first rounding operation may include any one of the following operations: rounding up, rounding down, and rounding off. Optionally, the duration of the CGT of the first CG is associated with the period, K and M of the first CG. Optionally, the duration of the CGT of the first CG satisfies any of the following: or or C=K×TM. For example, C is the duration of the CGT of the first CG. For example, Indicates floor operation. For example, T is the period of the first CG. For example, M is greater than zero. For example, K is the CGT information of the first CG. Optionally, the configuration information of the first CG also includes information of the CGT of the first CG. For example, the information of the CGT of the first CG includes / is: K. Optionally, the unit of K×T or T may be milliseconds, subframes, time slots or symbols. Optionally, the unit of M may be milliseconds, subframes, time slots or symbols, which is not limited in the embodiments of the present application. Optionally, the unit of K×T or T is the same as the unit of M. For example, if K×T or the unit of T is milliseconds, M may be 1 millisecond. For example, K may be configured by a network device to a terminal device, may be pre-configured by a protocol, may be determined by the terminal device itself, or may be determined by other means, and this application does not limit this. For example, M may be configured by a network device to a terminal device, may be pre-configured by a protocol, may be determined by the terminal device itself, or may be determined by other means, and this application does not limit this. Optionally, Optionally, in a possible implementation, when the unit of the period of the first CG is milliseconds or subframes, the duration of the CGT of the first CG satisfies any of the following: C = F{K×T}; or, C = K × F{T}; or, C=K×TM;. For example, F{} is the first rounding operation. For example, in this case, the unit of M is milliseconds or subframes. For example, in this case, M is greater than or equal to K×TF{K×T}, or, M is greater than or equal to K×TK×F{T}. Optionally, in a possible implementation, when the unit of the period of the first CG is milliseconds or subframes, the duration of the CGT of the first CG satisfies any of the following: C = F{K×T×X}, or C = K × F {T × X}, or C = K × T × XM. For example, X is the number of time slots included in one millisecond or one subframe. Optionally, "×X" may include / replaced by: / 10×numberOfSlotsPerFrame, or, ÷10×numberOfSlotsPerFrame. Optionally, "X" may include / be replaced by: numberOfSlotsPerFrame / 10, or, numberOfSlotsPerFrame÷10. Optionally, "÷X" may include / be replaced by: ×10 / numberOfSlotsPerFrame, or, ×10÷numberOfSlotsPerFrame. For example, numberOfSlotsPerFrame indicates the number of time slots contained in a frame. For example, in this case, the unit of M is time slot. For example, in this case, M is greater than or equal to K×T×XF{K×T×X}, or, M is greater than or equal to K×T×XK×F{T×X}. Optionally, in a possible implementation, when the unit of the period of the first CG is milliseconds or subframes, the duration of the CGT of the first CG satisfies any of the following: C = F{K×T×Y}, or C = K × F {T × Y}, or C = K × T × YM. For example, Y is the number of symbols contained in one millisecond or one subframe. Optionally, “×Y” may include / replaced by: / 10×numberOfSlotsPerFrame×numberOfSymbolsPerSlot, or, ÷10×numberOfSlotsPerFrame×numberOfSymbolsPerSlot. Optionally, "Y" may include / be replaced by: numberOfSlotsPerFrame×numberOfSymbolsPerSlot / 10, or, numberOfSlotsPerFrame×numberOfSymbolsPerSlot÷10. Optionally, “÷Y” may include / be replaced by: ×10 / numberOfSlotsPerFrame / numberOfSymbolsPerSlot, or, ×10÷numberOfSlotsPerFrame÷numberOfSymbolsPerSlot. For example, numberOfSlotsPerFrame indicates the number of time slots contained in a frame. For example, numberOfSymbolsPerSlot indicates the number of symbols contained in a time slot. For example, in this case, the units of M are symbols. For example, in this case, M is greater than or equal to K×T×YF{K×T×Y}, or, M is greater than or equal to K×T×YK×F{T ×Y}. Optionally, in another possible implementation, when the unit of the period of the first CG is a time slot, the duration of the CGT of the first CG satisfies any of the following: C = F{K×T÷X}; or, C = K × F {T ÷ X}; or, C = K × T ÷ XM; or, For example, in this case, the unit of M is milliseconds or subframes. For example, in this case, M is greater than or equal to K×T÷XF{K×T÷X}, or, M is greater than or equal to K×T÷XK×F{T÷X}. Optionally, in another possible implementation, when the unit of the period of the first CG is a time slot, the duration of the CGT of the first CG satisfies any of the following: C = F{K×T}, or C = K × F{T}, or C=K×TM. For example, in this case, the unit of M is time slot. For example, in this case, M is greater than or equal to K×TF{K×T}, or, M is greater than or equal to K×TK×F{T}. Optionally, in another possible implementation, when the unit of the period of the first CG is a time slot, the duration of the CGT of the first CG satisfies any of the following: C = F{K×T×Z}, or C = K × F {T × Z}, or C=K×T×ZM. For example, Z is the number of symbols contained in a time slot. Optionally, Z can be expressed as numberOfSymbolsPerSlot. For example, in this case, the units of M are symbols. For example, in this case, M is greater than or equal to K×T×ZF{K×T×Z}, or, M is greater than or equal to K×T×ZK×F{T×Z}. Optionally, in another possible implementation, when the unit of the period of the first CG is a symbol, the duration of the CGT of the first CG satisfies any of the following: C = F{K×T÷Y}; or, C = K × F {T ÷ Y}; or, C=K×T÷YM.

For example, in this case, the unit of M is time slot. For example, in this case, M is greater than or equal to K×T÷ZF{K×T÷Z}, or, M is greater than or equal to K×T÷ZK×F{T÷Z}. Optionally, in another possible implementation, when the unit of the period of the first CG is a symbol, the duration of the CGT of the first CG satisfies any of the following: C = F{K×T}, or C = K × F{T}, or C=K×TM. For example, in this case, the units of M are symbols. For example, in this case, M is greater than or equal to K×TF{K×T}, or, M is greater than or equal to K×TK×F{T}. In the embodiment of the present application, the duration of the CGT of the first CG is less than (the period of the first CG × K), which is conducive to avoiding the problem of unavailable CG opportunities in certain CG periods. This is conducive to improving the resource utilization of the system, improving the system capacity, reducing the data transmission delay, and facilitating user experience. In order to solve the problem of some CG opportunities being unavailable in mode 2, the present application also provides a communication method, where the duration of CGT is no longer equal to an integer multiple of the CG cycle, but is slightly less than (CG cycle × K ÷ N), which is helpful to avoid the problem of CG opportunities being unavailable in some CG cycles. This is beneficial to improving the resource utilization of the system, improving the system capacity, reducing data transmission delay, and facilitating user experience. FIG15 shows a schematic flow chart of another communication method 1500 provided in an embodiment of the present application. The method 1500 includes: S1510, the terminal device obtains the configuration information of the first CG. For example, the terminal device obtains the configuration information of the first CG may include / be replaced by: the terminal device receives the configuration information of the first CG.

For example, in the embodiment of the present application, the content related to the duration of the first timer can refer to the introduction of the duration of the CGT of the first CG in the embodiment described in Figure 14 or Figure 15. For example, the duration of the CGT of the first CG in the embodiment described in Figure 14 or Figure 15 is replaced with the duration of the first timer for understanding. Case 1: the period of the first CG is a non-integer, and the duration of the first timer is less than (the period of the first CG × K).

The communication method of the embodiment of the present application avoids the problem of unavailable CG opportunities in certain CG cycles by introducing a new timer, which is beneficial to improving the resource utilization of the system, improving the system capacity, reducing data transmission delay, and improving user experience.
