[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on October 31, 2023, with application number 202311441023.1 and application name “A Transmission Method and Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of wireless communication technology, and in particular to a transmission method and device. Background Art

[0004] With the continuous evolution of cellular communication technology, network transmission bandwidth continues to increase. The increase in peak-to-average power ratio (PAPR) has led to a gradual decrease in power amplifier (PA) efficiency, resulting in an increase in the transmit power consumption of network equipment. The rapid increase in transmission channels has also led to an increase in the system's static power consumption. To reduce system power consumption, network equipment can configure terminals to activate cell discontinuous reception (DRX), which prevents terminals from transmitting on certain channels during periods of cell DRX inactivity.

[0005] To meet service requirements, the NR protocol introduces a configured grant physical uplink shared channel (CG PUSCH) for augmented reality services (XR). This channel is used to transmit services with high priority and low latency requirements.

[0006] However, if the terminal activates cell DRX, how to send XR CG PUSCH during the inactive period of the cell DRX cycle is a problem that needs to be solved.

[0007] Summary of the Invention

[0008] The embodiments of the present application provide a transmission method and apparatus to solve the problem of how to send a first CG PUSCH during an inactive period of a transmission configuration period.

[0009] The communication system to which the embodiments of the present application are applicable includes a network device and a terminal device. The network device can activate a transmission configuration on the terminal device through a first indication information, such as a cell DRX transmission configuration; when the terminal device performs an XR service, it can determine whether to transmit the first CG PUSCH for carrying the XR service within the first time period (inactive time period) indicated by the transmission configuration, and can send uplink information to the network device to indicate the transmission status of the CG PUSCH resource.

[0010] The following describes the embodiments of the present application.

[0011] In a first aspect, a transmission method is provided, which can be applied to a terminal device. The method may include: the terminal device receiving first indication information, the first indication information being used to activate not transmitting a first uplink channel in a first cell in a first time period, the first uplink channel including a CG PUSCH; and the terminal device sending first uplink information on a first CG PUSCH resource of the first cell, the first CG PUSCH resource being within the first time period.

[0012] In one possible implementation, the first indication information is used to activate not transmitting the first uplink channel in the first cell in the first time period. The alternative description is that the first indication information is used to activate the discontinuous reception configuration of the first cell, and the discontinuous reception configuration of the first cell includes not transmitting the first uplink channel in the first cell in the first time period of the first cycle.

[0013] Optionally, the first uplink information indicates the transmission status of N CG PUSCH resources, the time domain positions of the N CG resources are after the time domain position of the first CG PUSCH resource, and N is a positive integer greater than 1.

[0014] Optionally, the method also includes: the terminal device sending the first CG PUSCH on the first CG PUSCH resource of the first cell.

[0015] The above implementation solves the problem of how to transmit the first CG PUSCH on the CG PUSCH resources in the first time period, and clarifies how to indicate the CG PUSCH resources in the inactive time period in the UTO-UCI. For XR services, since in the embodiment of the present application, XR CG PUSCH transmission can be performed on the XR CG PUSCH resources in the inactive time period of the cell DRX cycle, the high priority and low latency requirements of XR services can be met.

[0016] In one possible implementation, before sending the first uplink information on the first CG PUSCH resource of the first cell, the method further includes: sending second uplink information on the second CG PUSCH resource of the first cell, where the second uplink information indicates a transmission state of the first CG PUSCH resource, where the transmission state of the first CG PUSCH resource is transmission. In this manner, if the second uplink information indicates that the transmission state of the first CG PUSCH resource is transmission, the terminal may transmit information on the first CG PUSCH resource even if the first CG PUSCH resource is within the first time period.

[0017] In a possible implementation, the second uplink information may replace the indication information described as the transmission status of the CG PUSCH.

[0018] Furthermore, the second uplink information indicates the transmission status of the CG PUSCH resource. For the receiving end, the receiving end can know which CG PUSCH resources have CG PUSCH transmissions and which CG PUSCH resources do not have CG PUSCH transmissions. For CG PUSCH resources without CG PUSCH transmissions, the receiving end may not perform reception, thereby saving power consumption at the receiving end. For example, if the receiving end is a base station, this method is beneficial for energy saving of the base station.

[0019] In a possible implementation, the second uplink information is UTO-UCI, which indicates the transmission status of the first CG PUSCH resource.

[0020] In one possible implementation, the first CG PUSCH resource belongs to a first CG cycle, and the first CG cycle also includes a third CG PUSCH resource, and the third CG PUSCH resource is not in the first time period. This method can be alternatively described as follows: if, among the CG PUSCH resources in a CG cycle, some CG PUSCH resources are located in the first time period and the other part of the CG PUSCH resources are located outside the first time period, then the transmission status of the CG PUSCH in the first time period is that the corresponding data service (for example, XR service) can be transmitted.

[0021] In one possible implementation, the method further includes: determining that a fourth CG PUSCH resource does not transmit the first CG PUSCH; wherein the fourth CG PUSCH resource belongs to a second CG cycle, and all CG PUSCH resources in the second CG cycle are located in the first time period. This method can be alternatively described as follows: if all CG PUSCH resources in a CG cycle are located in the first time period, then the transmission status of the CG PUSCH in the first time period is not transmitting corresponding data services (e.g., XR services).

[0022] In one possible implementation, the method further includes: sending third uplink information on the fifth CG PUSCH resource of the first cell, the third uplink information indicating the transmission status of the fourth CG PUSCH resource, and the transmission status of the fourth CG PUSCH resource is non-transmission.

[0023] In one possible implementation, the first time period includes a fourth CG PUSCH resource, the fourth PUSCH resource belongs to a second CG cycle, and all CG PUSCH resources in the second CG cycle are located in the first time period. In this manner, if all CG PUSCH resources in a CG cycle are located in the first time period, no service information is transmitted on the CG PUSCH resources in the CG.

[0024] In a possible implementation, the method further includes: when determining the third uplink information, determining the fourth CG PUSCH resource in the second CG period as an invalid resource.

[0025] In one possible implementation, the third uplink information does not indicate the transmission status of CG PUSCH resources that are determined to be invalid resources. In this manner, the third uplink information indicates the transmission status of valid resources without indicating the transmission status of invalid resources, which can save resources used by the terminal to send the third uplink information.

[0070] The embodiments of the present application can be applied to various communication systems, such as: global system for mobile communications (GSM) system, code division multiple access (CDMA) system, wideband code division multiple access (WCDMA) system, general packet radio service (GPRS), long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD), universal mobile telecommunication system (UMTS), world-wide interoperability for microwave access (WIMAX) communication system, fifth generation (5G) system or new radio (NR), or applied to future communication systems or other similar communication systems.

[0071] Figure 1 is a schematic diagram of the architecture of a communication system 1000 used in an embodiment of the present application. As shown in Figure 1 , the communication system includes a radio access network 100 and a core network 200. Optionally, the communication system 1000 may also include the Internet 300. The radio access network 100 may include at least one radio access network device (such as 110a and 110b in Figure 1 ) and at least one terminal (such as 120a-120j in Figure 1 ). The terminal is wirelessly connected to the radio access network device, and the radio access network device is wirelessly or wiredly connected to the core network. The core network device and the radio access network device may be independent, distinct physical devices, or the core network device's functions and the radio access network device's logical functions may be integrated into the same physical device, or a single physical device may integrate some of the core network device's functions and some of the radio access network device's functions. Terminals and radio access network devices may be interconnected via wired or wireless connections. Figure 1 is merely a schematic diagram. The communication system may also include other network devices, such as wireless relay devices and wireless backhaul devices, which are not shown in Figure 1 .

[0072] A radio access network device can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a fifth-generation (5G) mobile communication system, a next-generation base station in a sixth-generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a Wi-Fi system. It can also be a module or unit that performs some of the functions of a base station, such as a centralized unit (CU) or a distributed unit (DU). The CU performs the functions of the base station's radio resource control protocol and packet data convergence protocol (PDCP), as well as the service data adaptation protocol (SDAP). The DU performs the functions of the base station's radio link control layer and medium access control (MAC) layer, as well as some or all of the physical layer. For detailed descriptions of each of these protocol layers, please refer to the relevant technical specifications of the Third Generation Partnership Project (3GPP). The wireless access network device can be a macro base station (such as 110a in Figure 1), a micro base station or an indoor station (such as 110b in Figure 1), a relay node, a donor node, etc. The embodiments of this application do not limit the specific technology and device form used by the wireless access network device. For ease of description, the following description uses a network device as an example of a wireless access network device.

[0073] A terminal may also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. The terminal can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, smart city, etc. The terminal can be a mobile phone, tablet computer, computer with wireless transceiver function, wearable device, vehicle, drone, helicopter, airplane, ship, robot, robotic arm, smart home device, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal.

[0074] Network devices and terminals can be fixed or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; on water; and on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of network devices and terminals.

[0075] The roles of network devices and terminals can be relative. For example, the helicopter or drone 120i in Figure 1 can be configured as a mobile network device. With respect to the terminal 120j accessing the wireless access network 100 via 120i, drone 120i is a network device. However, with respect to network device 110a, 120i is a terminal, meaning that communication between 110a and 120i occurs via a wireless air interface protocol. Of course, communication between 110a and 120i can also occur via an interface protocol between network devices. In this case, 120i is also a network device relative to 110a. Therefore, both network devices and terminals can be collectively referred to as communication devices. 110a and 110b in Figure 1 can be referred to as communication devices with network device functionality, while 120a-120j in Figure 1 can be referred to as communication devices with terminal functionality.

[0076] Communication between network devices and terminals, between network devices, and between terminals can be carried out through authorized spectrum, unauthorized spectrum, or both; communication can be carried out through spectrum below 6 gigahertz (GHz), spectrum above 6 GHz, or spectrum below 6 GHz and spectrum above 6 GHz. The embodiments of the present application do not limit the spectrum resources used for wireless communication.

[0077] In the embodiments of the present application, the functions of the network device may also be performed by a module (such as a chip) in the network device, or by a control subsystem that includes the network device functions. The control subsystem that includes the network device functions here may be a control center in the above-mentioned application scenarios such as smart grid, industrial control, smart transportation, and smart city. The functions of the terminal may also be performed by a module (such as a chip or modem) in the terminal, or by a device that includes the terminal functions.

[0078] In order to make the purpose, technical solutions and advantages of this application more clear, the application will be further described in detail below with reference to the accompanying drawings. The specific operation methods in the method embodiments can also be applied to the device embodiments or system embodiments.

[0079] Below, some terms used in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0080] (1) Cell DRX

[0081] To achieve energy conservation, one possible inactive time approach is to configure a cycle of active time and inactive time for a cell of a terminal to achieve energy conservation. During the inactive time within the cycle, the terminal does not transmit certain signals, while during the active time within the cycle, the terminal can transmit the aforementioned signals / channels.

[0082] Cell DRX is an energy-saving technology for terminals in the RRC_CONNECTED state. Cell DRX can be configured at the cell level. Network equipment can send multiple cell DRX configurations to terminals via RRC signaling and enable (or activate) one of the multiple cell DRX configurations in a cell via downlink control information (DCI) or a MAC control element (CE).

[0083] It should be noted that, in the embodiment of the present application, cell DRX is an abbreviation of the above energy-saving technology, for example, the above energy-saving technology can also be called energy-saving mode 1, energy-saving configuration 1, etc. The present application does not limit the name of the energy-saving technology.

[0084] The cell DRX configuration may include one or more of the following information: cycle length, on-time, off-time, on-duration, or off-duration. The on-time refers to the start time of the active time period within the cell DRX cycle, the off-time refers to the start time of the inactive time period within the cell DRX cycle, the on-duration refers to the duration of the active time period, and the off-duration refers to the duration of the inactive time period.

[0085] For example, Figure 2 illustrates the active time and inactive time within a cell DRX cycle. By not sending or receiving these signals / channels during the inactive time, the terminal can save power consumption. As shown in Figure 2, a cell DRX cycle includes active time (also called an active period) and inactive time (also called an inactive period) in chronological order. In this embodiment of the present application, the inactive time within the cell DRX cycle is referred to as the first period, and the active time within the cell DRX cycle is referred to as the second period.

[0086] The channel / signal transmitted during the active time in the cell DRX cycle may be an uplink channel or an uplink signal.

[0087] Exemplarily, the uplink channel may include at least one of the following channels: a configured grant PUSCH (CG PUSCH; PUSCH is the English abbreviation of physical uplink shared channel); a hybrid automatic repeat request feedback (HARQ-ACK) of a semi-persistent scheduled physical downlink shared channel (SPS PDSCH); a scheduling request (SR); a physical random access channel (PRACH); a random access message A; a random access message 3; periodic channel state information (P-CSI); semi-persistent CSI (SP-SCI); and an uplink scheduling request with low media access control (MAC) layer priority logical channel association / low physical layer priority.

[0088] (2)XR CG PUSCH

[0089] Uplink data transmission supports configured grant (CG) scheduling. The core of CG scheduling is that the network device configures semi-static uplink transmission resources (CG resources) for the terminal. When the semi-static uplink transmission resources are configured and activated, the terminal does not need to send a request when transmitting uplink data. Instead, it can transmit uplink information according to the uplink transmission resources corresponding to the semi-static CG resource configuration.

[0090] For XR (Extended Reality) services (a high-priority, low-latency requirement service), an XR CG configuration is introduced in the existing NR protocol, and XR services can be transmitted through XR CG PUSCH. Specifically, XR CG PUSCH refers to a CG PUSCH resource configured with the high-level parameter nrofSlots_InCGperiod, or a CG PUSCH resource associated with the high-level parameter nrofSlots_InCGperiod. In other words, the high-level parameter nrofSlots_InCGperiod is configured (or included or exists) on the configuredGrantConfig field corresponding to the CG PUSCH resource, that is, the CG PUSCH resource configured with this high-level parameter is the XR CG PUSCH resource. The XR CG PUSCH resources in one or more time slots can form a CG period, and the above-mentioned high-level parameter nrofSlots_InCGperiod configures the number of consecutive time slots corresponding to a CG period.

[0091] It is understandable that CG PUSCH resources have multiple interchangeable names, such as CG PUSCH transmission opportunity or CG PUSCH transmission resource.

[0092] (3) Unused transmission occasion-uplink control information (UTO-UCI)

[0093] For XR CG PUSCH, the NR protocol also introduces uplink information such as UTO-UCI. Specifically, the terminal can transmit CG PUSCH on a CG PUSCH resource while also sending a UTO-UCI. The UTO-UCI is used to indicate the transmission status of multiple CG PUSCH resources after the CG PUSCH resource. Among them, the transmission status of a CG PUSCH resource can be "transmission" or "non-transmission", where "transmission" means that the terminal device can use the CG PUSCH resource to transmit XR CG PUSCH, and "non-transmission" means that the CG PUSCH resource does not transmit XR CG PUSCH. Accordingly, if the network device determines that the transmission status of the CG PUSCH resource is "transmission" based on the UTO-UCI sent by the terminal, the XR CG PUSCH can be received on the resource. If the network device determines that the transmission status of the CG PUSCH resource is "non-transmission" based on the UTO-UCI sent by the terminal, the XR CG PUSCH will not be received on the resource.

[0094] Specifically, the UTO-UCI may consist of multiple bits, each bit corresponding to a CG PUSCH resource, and is used to indicate the transmission status of the corresponding CG PUSCH resource. If the bit value is set to 0, it indicates that the terminal may send an XR CG PUSCH on the corresponding CG PUSCH resource. If the bit value is set to 1, it indicates that the terminal does not transmit an XR CG PUSCH on the corresponding CG PUSCH resource. Figure 3 illustrates an example of a UTO-UCI. As shown in Figure 3, the length of the UTO-UCI is configured to be 4. The UTO-UCI is reported in the CG PUSCH resource indicated by the black arrow in the figure. The value of the UTO-UCI is "0100", which is used to indicate that in the four CG PUSCH resources following the CG PUSCH resource (i.e., the CG PUSCH resource containing the UTO-UCI), the terminal may use the first, third, and fourth CG PUSCH resources to transmit the XR CG PUSCH, and not use the second CG PUSCH resource to transmit the XR CG PUSCH. It can be understood that the terminal will transmit XR CG PUSCH on the 1st, 3rd and 4th resources, and will also report a 4-bit UTO-UCI in these CG PUSCH resources respectively. Each UTO-UCI indicates the transmission status of the next 4 CG PUSCH resources at their respective time domain positions.

[0095] It is worth mentioning that the UTO-UCI only indicates the transmission status of valid CG PUSCH resources. That is, when determining the indication content of the UTO-UCI, CG PUSCH resources that are considered invalid resources need to be excluded. In the current protocol, in unpaired spectrum scenarios, CG PUSCH resources that do not meet the frame structure configuration (for example, the CG PUSCH resources are within the downlink transmission time slot) are considered invalid CG PUSCH resources.

[0096] Currently, the protocol has not yet defined how the terminal sends XR CG PUSCH during the inactive period of the cell DRX cycle. In other words, the behavior of the terminal in this scenario is ambiguous.

[0097] To address the above-mentioned issues, embodiments of the present application provide a transmission method and apparatus. To further clarify the objectives, technical solutions, and advantages of this application, the present application will be further described below in conjunction with the accompanying drawings. The specific operating methods described in the method embodiments can also be applied to the apparatus embodiments or system embodiments.

[0098] Based on the network system architecture shown in FIG1 and the related technical descriptions above, FIG4 exemplarily illustrates a flow chart of a transmission method provided by an embodiment of the present application. The solution in FIG4 is described using the interaction between a network device and a terminal device as an example. The relevant descriptions of the network device and the terminal device are referred to above and are not repeated here.

[0099] 4 is a flow chart of a transmission method provided in an embodiment of the present application. The flow may include the following steps:

[0100] Step 401: The network device sends first indication information to the terminal device, and correspondingly, the terminal device receives the first indication information.

[0101] The first indication information is used to activate not transmitting the first uplink channel in the first cell during the first time period, or the first indication information indicates that the terminal device does not transmit the first uplink channel in the first cell during the first time period, and the first uplink channel includes the first CG PUSCH. It can be understood that the first indication information is used to activate a transmission configuration, and the transmission configuration is specifically not transmitting the first uplink channel in the first cell during the first time period, and the first uplink channel includes the first CG PUSCH. In a possible implementation, the network device can configure one or more transmission configurations through configuration signaling, such as RRC signaling, and subsequently activate one of the transmission configurations through the above-mentioned first indication information. The activation of a transmission configuration can also be understood as enabling the transmission configuration, or making the transmission configuration effective.

[0102] In one possible implementation, the first indication information is used to activate the cell DRX configuration. For relevant descriptions of the cell DRX configuration, please refer to the previous text and will not be repeated here. In the embodiment of the present application, the inactive time within the cell DRX cycle is referred to as the first time period, and the active time period is referred to as the second time period.

[0103] In an embodiment of the present application, after receiving the first indication information, the terminal device may activate the cell DRX configuration according to the first indication information. The cell DRX configuration activated by the first indication information specifically includes: not transmitting a first uplink channel in the first cell during a first time period, the first uplink channel including a first CG PUSCH. Because the first uplink channel includes the first CG PUSCH, the transmission of the first CG PUSCH may be affected by the cell DRX configuration.

[0104] The first CG PUSCH includes an XR CG PUSCH. The description of the XR CG PUSCH can refer to the above description of the XR CG PUSCH and will not be repeated here. In an embodiment of the present application, the first CG PUSCH can be carried by one or more CG PUSCH resources, or the first CG PUSCH can be transmitted by one or more CG PUSCH resources. In an embodiment of the present application, the CG PUSCH resources may include first CG PUSCH resources, second CG PUSCH resources, third CG PUSCH resources, and so on.

[0105] It can be understood that since the transmission configuration activated by the terminal device is not to transmit the first uplink channel in the first cell in the first time period, the first uplink channel includes the first CG PUSCH, and therefore the one or more CG PUSCH resources used to carry (or transmit) the first CG PUSCH are resources of the first cell. To simplify the expression, some of the following descriptions omits the limitation that resources such as the first CG PUSCH resources and the second PUSCH resources are resources of the first cell.

[0106] Optionally, the first uplink channel may include one or more other uplink channels in addition to the first CG PUSCH. For specific examples, please refer to the above and will not be repeated here. The terminal device does not transmit the other one or more uplink channels in the first time period to reduce power consumption.

[0107] Step 402: The terminal device activates the above transmission configuration according to the first indication information.

[0108] Step 403: The terminal device sends first uplink information on a first CG PUSCH resource of the first cell, where the first CG PUSCH resource is within the first time period.

[0109] Optionally, the first uplink information indicates the transmission status of N CG PUSCH resources, the time domain positions of the N CG PUSCH resources are after the time domain position of the first CG PUSCH resource, and N is an integer greater than 1.

[0110] It can be understood that the N CG PUSCH resources are the N CG PUSCH resources following the first CG PUSCH resource in the time domain. Taking N=4 as an example, an example of the first CG PUSCH resource and the four CG PUSCH resources following it can be shown in FIG3 .

[0111] In one possible implementation, the terminal device may also send the first CG PUSCH on the first CG PUSCH resource. That is, the terminal device may transmit the first CG PUSCH on the CG PUSCH resource during the inactive period of the cell DRX cycle and indicate the transmission status of the next N CG PUSCH resources on the CG PUSCH resource.

[0112] In one possible implementation, the first uplink information is UTO-UCI. The UTO-UCI may include N bits (N is a positive integer greater than 1) to indicate the transmission status of the N CG PUSCH resources following the first CG PUSCH resource. Optionally, the transmission status of the N CG PUSCH resources may all be "transmission", or all be "non-transmission", or the transmission status of some CG PUSCH resources may be "transmission" and the transmission status of other CG PUSCH resources may be "non-transmission". For details, please refer to the following.

[0113] Optionally, in the UTO-UCI, the bit corresponding to a CG PUSCH resource may be set to a first value to indicate that the transmission status of the corresponding CG PUSCH resource is "transmission", or the bit corresponding to a CG PUSCH resource may be set to a second value to indicate that the transmission status of the corresponding CG PUSCH resource is "non-transmission". Optionally, the first value may be "0" and the second value may be "1".

[0114] It can be understood that the first uplink information can also be other data structures or data forms, as long as it can indicate the transmission status of the N CG PUSCH resources following the first CG PUSCH resource. This embodiment of the present application does not limit this.

[0115] In an embodiment of the present application, the terminal device can transmit the first CG PUSCH on the CG PUSCH resources in the second time period. Accordingly, when reporting the UTO-UCI, the terminal sets the transmission status of the CG PUSCH resources in the second time period to "transmission".

[0116] The above-mentioned embodiments of the present application solve the problem of how to transmit the first CG PUSCH on the CG PUSCH resources within the first time period, and clarify how to indicate the CG PUSCH resources in the inactive time period in the UTO-UCI. For XR services, since in the embodiments of the present application, XR CG PUSCH transmission can be performed on the XR CG PUSCH resources within the inactive time period of the cell DRX cycle, the high priority and low latency requirements of the XR services can be met. Furthermore, the embodiments of the present application can determine the number of resources for transmitting XR CG PUSCH in the inactive time period of the cell DRX cycle based on the data volume of the XR service, thereby improving the flexibility of the system, and can also take into account the power consumption overhead while ensuring the high priority and low latency requirements of the XR service.

[0117] In one possible implementation, before the terminal device sends the first uplink information on the first CG PUSCH resource, the further step includes: the terminal device sends the second uplink information on the second CG PUSCH resource of the first cell, wherein the second uplink information indicates the transmission status of the first CG PUSCH resource, and the transmission status of the first CG PUSCH resource is transmission. That is, the transmission status of the first CG PUSCH resource is indicated by the second uplink information sent on the second CG PUSCH resource before the first CG PUSCH resource, and the transmission status of the first CG PUSCH resource indicated by the second uplink information is "transmission". In this way, the terminal device can transmit the CG PUSCH and the first uplink information on the first CG PUSCH resource.

[0118] It can be understood that the time domain position of the second CG PUSCH resource is before the time domain position of the first CG PUSCH resource, the second CG PUSCH resource may be adjacent to the first CG PUSCG resource, and the second CG PUSCH resource may also be separated from the first CG PUSCG resource by one or more CG PUSCH resources. The number of spaced CG PUSCH resources is related to the value of N, or the number of bits of UTO-UCI.

[0119] It can be understood that the second CG PUSCH resource may be located in the first time period or in the second time period.

[0120] For example, taking N=4 as an example, as shown in FIG5a , when the second CG PUSCH resource (represented as CG PUSCH resource 0 in the figure) is located in the second time period, the first CG PUSCH resource may be any one of CG PUSCH resources 1, 2, 3, and 4 in FIG5a . As shown in FIG5b , taking the UTO-UCI sent by CG PUSCH resource 0 as "0011" as an example, it indicates that the transmission status corresponding to CG PUSCH resource 1 and CG PUSCH resource 2 is set to "0", indicating that the first CG PUSCH can be transmitted, and the transmission status of CG PUSCH resource 3 and CG PUSCH resource 4 is set to "1", indicating that the first CG PUSCH is not transmitted. When the terminal device transmits the first CG PUSCH on CG PUSCH resource 1, it can report UTO-UCI at the same time. For example, the UTO-UCI reported on CG PUSCH resource 1 is "0110", where the last bit indicates the transmission status of CG PUSCH resource 5. Since CG PUSCH resource 5 is located in the active time period of the cell DRX cycle, its transmission status is set to "0", indicating that the first CG PUSCH can be transmitted; when the terminal device transmits the first CG PUSCH on CG PUSCH resource 2, it can report UTO-UCI at the same time. For example, the UTO-UCI reported on CG PUSCH resource 2 is "1100", where the last two bits indicate the transmission status of CG PUSCH resources 5 and 6. Since CG PUSCH resources 5 and 6 are located in the active time period of the cell DRX cycle, their transmission status is set to "0", indicating that CG PUSCH can be transmitted.

[0121] It can be understood that the embodiment of the present application is described by setting the transmission status to "0" to indicate that the first CG PUSCH can be transmitted. Of course, the transmission status can also be set to "1" to indicate that the first CG PUSCH can be transmitted; or multiple bits can be used to indicate the transmission status of a first CG PUSCH resource. Accordingly, there are more possible values ​​for the transmission status; or a joint coding method can be used to indicate, that is, various combinations of different transmission states of N CG PUSCH resources are encoded separately, and the terminal device can report a code to indicate a combination of the transmission states of N CG PUSCH resources. This application does not impose any restrictions on this.

[0122] For another example, still taking N=4 as an example, as shown in FIG6a , when the second CG PUSCH resource (represented as CG PUSCH resource 0 in the figure) is located in the first time period, the second CG PUSCH resource may be any one of CG PUSCH resources 1, 2, and 3 in FIG6a . As shown in FIG6b , taking the UTO-UCI sent by CG PUSCH resource 0 as "0110" as an example, it indicates that the transmission status of CG PUSCH resource 1 is set to "0", indicating that the first CG PUSCH can be transmitted, and the transmission status of CG PUSCH resources 2 and 3 is set to "1", indicating that the first CG PUSCH is not transmitted. Since CG PUSCH resource 4 is located in the active time period of the cell DRX cycle, its transmission status is set to "0", indicating that the CG PUSCH can be transmitted. When the terminal device transmits the first CG PUSCH on CG PUSCH resource 1, it can report UTO-UCI at the same time. For example, the UTO-UCI reported on CG PUSCH resource 1 is "1100", where the last two bits indicate the transmission status of CG PUSCH resources 4 and 5. Since CG PUSCH resources 4 and 5 are located in the active time period of the cell DRX cycle, their transmission status is set to "0", indicating that the first CG PUSCH can be transmitted.

[0123] Although Figures 5b and 6b illustrate examples of CG PUSCH transmissions using multiple CG PUSCH resources within a first time period, it is understood that it is also possible that only one CG PUSCH resource is used for the first CG PUSCH transmission within the first time period. The number of CG PUSCH resources used for CG PUSCH transmission within the first time period is related to the data volume of the XR service. The data volume of the XR service may be large and require the use of multiple CG PUSCH resources for transmission. For example, in Figure 5b , the terminal device determines that the XR service cannot be fully transmitted using CG PUSCH resource 0 within the active time period of the cell DRX cycle and requires two more CG PUSCH resources for transmission. Therefore, the terminal device sets the transmission status corresponding to CG PUSCH resources 1 and 2 within the subsequent inactive time period of the cell DRX cycle to "transmit" and uses CG PUSCH resources 1 and 2 to transmit the first CG PUSCH. Of course, if the data volume of the XR service is large and cannot be fully transmitted using CG PUSCH resources 1 and 2, all CG PUSCH resources within the active time period of the cell DRX cycle may be used for the first CG PUSCH transmission.

[0124] One exception is that if the terminal device determines that the XR service can transmit the data of the XR service using the CG PUSCH resource 0 in the active time period of the cell DRX cycle, the transmission status corresponding to the next multiple CG PUSCH resources (such as CG PUSCH resources 1, 2, 3, and 4) in the inactive time period of the cell DRX cycle can be set to "not transmitted", and the terminal device does not use CG PUSCH resources 1, 2, 3, and 4 to transmit the first CG PUSCH.

[0125] In one possible implementation, the first CG PUSCH resource belongs to a first CG cycle, and the first CG cycle also includes a third CG PUSCH resource, and the third CG PUSCH resource is not in the first time period. That is, the first CG cycle includes multiple CG PUSCH resources, some of which are located in the inactive time period of the cell DRX cycle (for example, including the above-mentioned first CG PUSCH resource), and the other part of the resources are located in the active time period of the cell DRX cycle (for example, including the above-mentioned third CG PUSCH resource). In this case, the CG PUSCH resources in the first CG cycle that are located in the inactive time period of the cell DRX cycle can be used for transmission of the first CG PUSCH.

[0126] Optionally, all CG PUSCH resources in the first time period within the first CG cycle are used for CG PUSCH transmission, and the transmission status corresponding to these resources is set to "transmission".

[0127] For example, Figure 7 shows the transmission status of CG PUSCH resources within the first CG cycle, taking the example of four CG PUSCH resources in the first CG cycle. As shown in the figure, there are four CG PUSCH resources in the first CG cycle, namely CG PUSCH resources 0, 1, 2, and 3. CG PUSCH resources 0 and 1 are in the active time period of the cell DRX cycle, and CG PUSCH resource 0 and / or CG PUSCH resource 1 are equivalent to the third CG PUSCH resource described above. CG PUSCH resources 2 and 3 are in the inactive time period of the cell DRX cycle, and CG PUSCH resource 2 and / or CG PUSCH resource 3 are equivalent to the first CG PUSCH resource described above. In this case, although CG PUSCH resources 2 and 3 in the first CG cycle are in the inactive time period of the cell DRX cycle, they are also used for first CG PUSCH transmission. When determining the UTO-UCI, the terminal sets the transmission status of CG PUSCH resources 2 and 3 to "transmission." Since CG PUSCH resources 0 and 1 are within the active time period of the cell DRX cycle, the terminal device can use CG PUSCH resources 0 and 1 for the first CG PUSCH transmission. When determining the UTO-UCI, the terminal device sets the transmission state of CG PUSCH resources 0 and 1 to "transmit". For example, as shown in Figure 7, the terminal device sends UTO-UCI on CG PUSCH resources 0, 1, 2, and 3 (as shown in the small boxes within each CG PUSCH resource in the figure).

[0128] In one possible implementation, the terminal device may also determine that the fourth CG PUSCH resource does not transmit the first CG PUSCH, wherein the fourth CG PUSCH resource belongs to the second CG period, and all CG PUSCH resources in the second CG period are located in the first time period. That is, the terminal device may determine that the CG PUSCH resources in the second CG period located in the first time period do not transmit the first CG PUSCH. Furthermore, the terminal device may also send third uplink information on the fifth CG PUSCH resource of the first cell, and the third uplink information indicates the transmission status of the fourth CG PUSCH resource, and the transmission status of the fourth CG PUSCH resource is not transmitted. That is, all CG PUSCH resources in the second CG period are located in the first time period, and the transmission status of one of the CG PUSCH resources is indicated in the third uplink information sent on the fifth CG PUSCH resource, and the transmission status of the CG PUSCH resource is set to "not transmitted".

[0129] Optionally, when determining the transmission state of CG PUSCH resources, or when determining the UTO-UCI, the terminal device sets the transmission state of any CG PUSCH resources within the second CG period to "not transmitted". In other words, the transmission state of all CG PUSCH resources within the second CG period is set to "not transmitted", and the first CG PUSCH is not transmitted on any CG PUSCH resources within the second CG period.

[0130] For example, Figure 8 uses the example of a first CG cycle and a second CG cycle each including four CG PUSCH resources. All CG PUSCH resources in the second CG cycle are located within the inactive time period of the cell DRX cycle. Therefore, the transmission status of all CG PUSCH resources in the second CG cycle is set to "non-transmission." Some CG PUSCH resources in the first CG cycle are located within the active time period of the cell DRX cycle, while others are located within the active time period of the cell DRX cycle. Therefore, all CG PUSCH resources in the first CG cycle located within the inactive time period of the cell DRX cycle are used to transmit the first CG PUSCH. In Figure 8, taking the example of using 8 bits of UTO-UCI to indicate the transmission status of 8 CG PUSCH resources, the UTO-UCI sent on the first CG PUSCH resource in the active time period of the cell DRX cycle is "00111111", where the 5th to 8th bits correspond to the 4 CG PUSCH resources in the second CG cycle, and their corresponding transmission status is set to "1", indicating that the first CG PUSCH is not transmitted. The 3rd and 4th bits correspond to the last two CG PUSCH resources in the first CG cycle. Since the first CG PUSCH can be transmitted using the third CG PUSCH resource in the first CG cycle, the transmission status corresponding to the third CG PUSCH resource in the first CG cycle can be set to "1"; the UTO-UCI sent on the second CG PUSCH resource in the active time period of the cell DRX cycle is "01111111", where the 3rd to 6th bits correspond to the 4 CG PUSCH resources in the second CG cycle, and their corresponding transmission status is set to "1", indicating that the first CG PUSCH is not transmitted.

[0131] In one possible implementation, the first time period includes all CG PUSCH resources in the second CG period, and the terminal device can determine that all CG PUSCH resources in the second CG period do not transmit the first CG PUSCH, or that all CG PUSCH resources in the second CG period are invalid resources, and the terminal device will not indicate the transmission status of all CG PUSCH resources in the second CG period in the first uplink information. That is to say, if all CG PUSCH resources in the second CG period are located in the first time period, the terminal will not transmit the first CG PUSCH on these resources, nor will it report the transmission status of these resources. For the network device, since the CG PUSCH resources are semi-statically configured on the network side, the network device can determine that the transmission status of all CG PUSCH resources in the second CG period is not included based on the first uplink information reported by the terminal device, and therefore it can be confirmed that these resources are determined by the terminal device as invalid resources, and therefore the network device will not receive the first CG PUSCH on these resources.

[0132] Exemplarily, FIG9 takes the example that the first CG cycle and the second CG cycle each include four CG PUSCH resources. All CG PUSCH resources in the second CG cycle are located in the inactive time period of the cell DRX cycle. Therefore, the terminal device does not transmit the first CG PUSCH in the CG PUSCH resources in the second CG cycle. Some CG PUSCH resources in the first CG cycle are in the active time period of the cell DRX cycle, and another part of the CG PUSCH resources are in the active time period of the cell DRX cycle. Therefore, all CG PUSCH resources in the first CG cycle that are located in the inactive time period of the cell DRX cycle are used to transmit the first CG PUSCH. In Figure 9, taking the example of using 4 bits of UTO-UCI to indicate the transmission status of 4 CG PUSCH resources, the UTO-UCI sent on the first CG PUSCH resource in the active time period of the cell DRX cycle is "0001", where the 2nd to 4th bits correspond to the last 3 CG PUSCH resources in the first CG period, and their corresponding transmission status is set to "0", indicating that the first CG PUSCH is transmitted, and the next 1 bit corresponds to the first of the last 2 CG PUSCH resources in the inactive time period, and its corresponding transmission status is set to "1", indicating that the first CG PUSCH is not transmitted; the UTO-UCI sent on the second CG PUSCH resource in the active time period of the cell DRX cycle is "0011", where the 1st to 2nd bits correspond to the last 2 CG PUSCH resources in the first CG period, and their corresponding transmission status is set to "0", indicating that the first CG PUSCH is transmitted, and the next 2 bits correspond to the last 2 CG PUSCH resources in the inactive time period, and their corresponding transmission status is set to "1", indicating that the first CG PUSCH is not transmitted.

[0133] In one possible implementation, the terminal device may determine the transmission state of the CG PUSCH resource based on the first parameter, such as determining the transmission state of the CG PUSCH resource within the first time period according to the first parameter. Exemplarily, the first parameter is used to indicate how the terminal device sets the transmission state of the CG PUSCH resource, such as how to set the transmission state of the CG PUSCH resource within the first time period, or the first parameter is used to indicate how the terminal device sets the transmission state of the CG PUSCH resource in the CG period according to whether the CG period overlaps with the first time period (including complete overlap or partial overlap); or the first parameter may also indicate under what circumstances the terminal device determines that the CG PUSCH resource is an invalid resource.

[0134] Optionally, the first parameter may be configured by a higher layer of the terminal device, or determined by a higher layer of the terminal device, or configured by a network device. Correspondingly, in a possible implementation, the network device may send configuration information including the first parameter to the terminal device.

[0135] Based on the network system architecture shown in FIG1 and the related technical descriptions above, FIG10 exemplarily illustrates a flow chart of a transmission method provided by another embodiment of the present application. The solution in FIG10 is described using the interaction between a network device and a terminal device as an example. The relevant descriptions of the network device and the terminal device are referred to above and are not repeated here.

[0136] 10 is a flow chart of a transmission method provided in an embodiment of the present application. The flow may include the following steps:

[0137] Step 1001: The network device sends first indication information, and correspondingly, the terminal device receives the first indication information.

[0138] Step 1002: The terminal device activates the transmission configuration according to the first indication information, such as activating the cell DRX configuration.

[0139] For the specific implementation of steps 1001 and 1002, reference may be made to the relevant steps in FIG4 .

[0140] Step 1003: The terminal device sends first uplink information on the first CG PUSCH resource of the first cell. Correspondingly, the network device receives the first uplink information on the first CG PUSCH resource.

[0141] The first uplink information indicates the transmission status of the second CG PUSCH resource, the transmission status of the second CG PUSCH is "not transmitted", and the second CG PUSCH resource is within the first time period. In other words, the terminal device does not transmit the first CG PUSCH on the CG PUSCH resource within the inactive time period of the cell DRX cycle, and its corresponding transmission status is "not transmitted".

[0142] In one possible implementation, the first uplink information is UTO-UCI. The UTO-UCI may include N bits (N is a positive integer greater than 1) to indicate the transmission status of N CG PUSCH resources following the first CG PUSCH resource. If M CG PUSCH resources among the N CG PUSCH resources are in the first time period, the transmission status corresponding to the M CG PUSCH resources is set to "not transmitted", where M is a positive integer greater than or equal to 1.

[0143] It can be understood that the first uplink information can also be other data structures or data forms, as long as it can indicate the transmission status of the N CG PUSCH resources following the first CG PUSCH resource. This embodiment of the present application does not limit this.

[0144] The above embodiments of the present application solve the problem of how to transmit the first CG PUSCH on the CG PUSCH transmission resources within the first time period, clarify how to indicate the CG PUSCH resources in the inactive time period in the UTO-UCI, and solve the problem of terminal side behavior ambiguity.

[0145] In one possible implementation, the second CG PUSCH resources belong to the first CG cycle, and the first CG cycle also includes third CG PUSCH resources. The third CG PUSCH resources are not in the first time period, or in other words, the third CG PUSCH resources are in the second time period. Accordingly, the terminal device can determine that the second CG PUSCH resources and / or the third CG PUSCH resources are not used for the first CG PUSCH transmission. That is, if some resources in the first CG cycle are in the first time period and the other part of the resources are in the second time period, then all CG PUSCH resources in the first CG cycle in the second time period do not transmit the first CG PUSCH, or in other words, all CG PUSCH resources in the first CG cycle do not transmit the first CG PUSCH.

[0146] Optionally, in one implementation, when determining the first uplink information, the terminal device indicates in the first uplink information that the second CG PUSCH resources located in the first time period of the first CG cycle, and / or the third CG PUSCH resources located in the second time period do not transmit the first CG PUSCH, and the terminal device may set the transmission resources of the second CG PUSCH resources and / or the third CG PUSCH resources to "not transmitted" in the uplink information. In another implementation, when determining the first uplink information, the terminal device determines the second CG PUSCH resources located in the first time period of the first CG cycle, and / or the third CG PUSCH resources located in the second time period as invalid resources, and does not indicate the transmission status of the second CG PUSCH resources and / or the third CG PUSCH resources in the first uplink information.

[0147] It can be understood that the number of second CG PUSCH resources located in the first time period within the above-mentioned first CG cycle may be one or more, and the number of third CG PUSCH resources located in the second time period within the above-mentioned first CG cycle may also be one or more.

[0148] In one possible implementation, the first time period includes all CG PUSCH resources in the second CG period, and the terminal device can determine that all CG PUSCH resources in the second CG period do not transmit the first CG PUSCH, and the terminal device can set the transmission resources of all PUSCH resources in the second CG period to "not transmitted". In another possible implementation, when determining the first uplink information, the terminal device can determine all CG PUSCH resources in the second CG period as invalid resources, and the terminal device will not indicate the transmission status of all CG PUSCH resources in the second CG period in the first uplink information. That is to say, if all CG PUSCH resources in the second CG period are located in the first time period, the terminal will not transmit the first CG PUSCH on these resources, nor will it report the transmission status of these resources. For the network device, since the CG PUSCH resources are semi-statically configured on the network side, the network device can determine that the transmission status of all CG PUSCH resources in the second CG period is not included based on the first uplink information reported by the terminal device, so it can be confirmed that these resources are considered to be invalid resources by the terminal device, and therefore the network device will not receive the first CG PUSCH on these resources.

[0149] For example, Figure 11a illustrates the transmission status of CG PUSCH resources within each CG cycle, taking a CG cycle including four CG PUSCH resources as an example. In Figure 11a, the transmission status of CG PUSCH resources corresponding to solid-line boxes containing cross-lines is "non-transmission," while the transmission status of CG PUSCH resources corresponding to solid-line boxes without cross-lines is "transmission." When generating the UTO-UCI, the terminal device sets the value of the corresponding bit to "1." For example, in which the UTO-UCI uses eight bits to indicate the transmission status of eight CG PUSCH resources, the UTO-UCI transmitted on CG PUSCH resource R1 is "01111111," and the UTO-UCI transmitted on CG PUSCH resource R2 is "111111111."

[0150] As another example, Figure 11b still takes a CG period including four CG PUSCH resources as an example, and shows the CG PUSCH resources determined to be invalid by the terminal device. In Figure 11b, the transmission status of the CG PUSCH resources corresponding to the solid-line boxes containing cross marks is "not transmitted", the transmission status of the CG PUSCH resources corresponding to the solid-line boxes without cross marks is "transmitted", and the CG PUSCH resources corresponding to the dotted-line boxes are invalid resources determined by the terminal device. When generating the UTO-UCI, the terminal device determines that all CG PUSCH resources within the two CG periods shown in the figure are invalid resources. Taking the example of UTO-UCI using 4 bits to indicate the transmission status of 4 CG PUSCH resources, the UTO-UCI sent on CG PUSCH resource R1 is "0001", and these 4 bits indicate in sequence: the transmission status of CG PUSCH resource R1, and the transmission status of CG PUSCH resources R3, R4 and R5 in the second time period of the next cell DRX cycle; the UTO-UCI sent by the terminal device on CG PUSCH resource R2 is "0011", and these 4 bits indicate in sequence: the transmission status of CG PUSCH resources R3, R4, R5 and R6 in the second time period of the next cell DRX cycle.

[0151] In a possible implementation, the terminal device may determine the transmission state of the CG PUSCH resource based on a first parameter. For the relevant description of the first parameter, reference may be made to the aforementioned embodiment.

[0152] Based on the network system architecture shown in FIG1 and the related technical descriptions above, FIG12 exemplarily illustrates a flow chart of a transmission method provided by another embodiment of the present application. The solution in FIG12 is described using the interaction between a network device and a terminal device as an example. The relevant descriptions of the network device and the terminal device are referred to above and are not repeated here.

[0153] 12 is a flow chart of a transmission method provided in an embodiment of the present application. The flow may include the following steps:

[0154] Step 1201: The network device sends first indication information, and correspondingly, the terminal device receives the first indication information.

[0155] The first indication information is used to activate the non-transmission of the first uplink channel in the first cell during the first time period, and the first uplink channel does not include the first CG PUSCH. It can be understood that the first indication information is used to activate a transmission configuration, and the transmission configuration is specifically that the first uplink channel is not transmitted in the first cell during the first time period, and the first uplink channel does not include the first CG PUSCH. In a possible implementation, the network device can configure one or more transmission configurations through configuration signaling, such as RRC signaling, and subsequently activate a transmission configuration through the above-mentioned first indication information. The activation of a transmission configuration can also be understood as enabling the transmission configuration, or making the transmission configuration effective.

[0156] In one possible implementation, the first indication information is used to activate the cell DRX configuration. For relevant descriptions of the cell DRX configuration, please refer to the previous text and will not be repeated here. In the embodiment of the present application, the inactive time within the cell DRX cycle is referred to as the first time period, and the active time period is referred to as the second time period.

[0157] In an embodiment of the present application, after receiving the first indication information, the terminal device may activate the cell DRX configuration according to the first indication information. The cell DRX configuration activated by the first indication information specifically includes: not transmitting a first uplink channel in the first cell in a first time period, the first uplink channel not including a first CG PUSCH. Since the first uplink channel does not include the first CG PUSCH, CG PUSCH transmission is not affected by the cell DRX configuration.

[0158] The first CG PUSCH includes an XR CG PUSCH. For the description of the XR CG PUSCH, reference may be made to the above description of the XR CG PUSCH, which will not be repeated here.

[0159] Optionally, the first uplink channel includes a second CG PUSCH, and the second CG PUSCH includes one or more of the following: a CG PUSCH with low priority at the physical layer, a CG PUSCH associated with a logical channel (Logical Channel, LCH) with low priority at the MAC layer, and a CG PUSCH without configuring the high-level parameter nrofSlots_InCGperiod.

[0160] Optionally, the physical layer low-priority CG PUSCH includes a CG PUSCH whose phy-PriorityIndex field is configured as p0.

[0161] Optionally, the CG PUSCH associated with the logical channel (Logical Channel, LCH) of low priority at the MAC layer may include, for example, an SR associated with a logical channel having a MAC priority greater than or equal to X, or a CG PUSCH associated with a logical channel having a priority (priority) configuration less than and / or equal to X of the logical channel configuration (LogicalChannelConfig), where X is an integer less than or equal to 16. In other words, the CG PUSCH associated with the logical channel LCH of low priority at the MAC layer can be understood as a CG PUSCH greater than or equal to a preset threshold, where the preset threshold may be preconfigured or configured.

[0162] For example, the preset threshold is a threshold of a priority configuration value. For example, if the preset priority configuration value threshold is 6, then a CG PUSCH with a priority configuration value greater than or equal to 6 is a CG PUSCH associated with a low-priority logical channel LCH of the MAC layer.

[0163] Alternatively, multiple LCHs are configured to be associated with CG PUSCHs at the same time, among which some LCHs with higher priority configuration values ​​are associated with CG PUSCHs.

[0164] For example, the priority configuration value of LCH#A is 1, the priority configuration value of LCH#B is 5, and the priority configuration value of LCH#C is 10. In one possible implementation, the CG PUSCH associated with the low-priority logical channel LCH at the MAC layer is LCH#C. In another possible implementation, the CG PUSCHs associated with the low-priority logical channel LCH at the MAC layer are LCH#C and LCH#B.

[0165] Optionally, the CG PUSCH not configured by the higher-layer parameter nrofSlots_InCGperiod may also be understood as a CG PUSCH not associated with the higher-layer parameter nrofSlots_InCGperiod, or one or more CG PUSCHs other than XR CG PUSCHs in the CG PUSCH.

[0166] Step 1202: The terminal device activates the above transmission configuration according to the first indication information, such as activating the cell DRX configuration.

[0167] Step 1203: The terminal device sends first uplink information on the first CG PUSCH resource of the first cell. Correspondingly, the network device receives the first uplink information on the first CG PUSCH resource.

[0168] The first uplink information indicates a transmission status of a second CG PUSCH resource. The second CG PUSCH resource may be located in the first time period or the second time period, and the transmission status of the second CG PUSCH resource may be "transmitting" or "not transmitting." That is, the transmission of the CG PUSCH is not affected by the cell DRX configuration, or the transmission status of the CG PUSCH resource is not affected by the cell DRX configuration.

[0169] Optionally, when the terminal device has XR service data to transmit, since the XR CG PUSCH transmission is not affected by the cell DRX configuration, even if the terminal device activates the cell DRX configuration, the terminal device can transmit the XR CG PUSCH during the inactive time of the cell DRX cycle, thereby meeting the XR service's latency requirements.

[0170] In a possible implementation, the terminal device may determine the transmission state of the CG PUSCH resource based on a first parameter. For the relevant description of the first parameter, reference may be made to the aforementioned embodiment.

[0171] In the above embodiments of the present application, XR CG PUSCH transmission is not affected by the cell DRX configuration. The terminal can choose to send XR CG PUSCH during the inactive time of the cell DRX cycle, which solves the problem of how the terminal sends XR CG PUSCH during the inactive time of the Cell DRX.
