However, with the development of communication technology, mobile communication systems will not only support traditional communications, but will also support, for example, device-to-device (D2D) communication, machine-to-machine (M2M) communication, machine-type communication (MTC), vehicle-to-vehicle (V2V) communication, or vehicle-to-everything (V2X) communication, etc. The embodiments of the present application can also be applied to these communication systems.

[0045] The embodiments of the present application can be applied to both non-terrestrial networks (NTN) and terrestrial networks (TN). NTNs generally use satellite communications to provide communication services to terrestrial users. Currently, NTN systems include NR-NTN and IoT-NTN systems, and may include other NTN systems in the future.

The network formed between the terminal device 301, the satellite 302, and the base station 303 can also be referred to as an NTN. In the architecture of the communication system shown in FIG3 , the satellite 302 may not have the function of a base station, and the communication between the terminal device 301 and the base station 303 needs to be transferred through the satellite 302. In this system architecture, the base station 303 can be referred to as a network device. In some embodiments of the present application, the communication system may include multiple base stations 303, each base station 303 can communicate with one or more satellites 302, and each satellite 302 can include other numbers of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

For convenience of description, the above-mentioned devices are collectively referred to as terminal devices. In the embodiments of the present application, "terminal device" and "UE" are often used interchangeably, but those skilled in the art will understand that the two can express the same meaning.

[0052] The network equipment mentioned in the embodiments of the present application may be an access network device, which may be located on the ground or on a satellite. An access network device is a device deployed in an access network to provide wireless communication functions for terminal devices. Access network devices may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems using different wireless access technologies, the names of devices with access network device functions may be different. For example, in a 5G NR system, they are called gNodeB or gNB. With the evolution of communication technology, the name "access network device" may change. For the convenience of description, in the embodiments of the present application, the above-mentioned devices that provide wireless communication functions for terminal devices are collectively referred to as access network devices. Optionally, a communication relationship can be established between a terminal device and a core network device through the access network device.

[0053] The "5G NR system" in the embodiments of the present application may also be referred to as a 5G system or an NR system, but those skilled in the art will understand its meaning. The technical solutions described in the embodiments of the present application may be applicable to LTE systems, 5G NR systems, subsequent evolution systems of 5G NR systems (e.g., B5G systems, 6G systems), and other communication systems such as NB-IoT (Narrow Band Internet of Things) systems, and this application does not limit this.

The cell can be a cell corresponding to the network device (for example, a base station). The cell can belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0055] Before introducing the technical solutions of this application, we first introduce and explain the related technologies involved in this application. The following related technologies can be combined with the technical solutions of the embodiments of this application as optional solutions, and they all fall within the scope of protection of the embodiments of this application. The embodiments of this application include at least part of the following contents.

[0056] 1. Network energy saving

[0057] Network energy conservation is crucial for environmental sustainability, reducing environmental impact (e.g., greenhouse gas emissions), and saving operating costs. As 5G becomes increasingly widespread across various industries and geographic regions, it will need to support very high data rates to handle more advanced services and applications (such as XR). Network deployments will become denser, using more antennas, greater bandwidth, and more frequency bands. Given the environmental impact of 5G, new, controlled solutions are needed to enhance network energy conservation.

[0058] Energy consumption has become a key component of operators' operational expenditures (OPEX). According to a report by the GSMA (Global System for Mobile communications Association), energy costs for mobile networks account for approximately 23% of total OPEX. Most of this energy consumption comes from the radio access network, more specifically, the active antenna unit (AAU), with data centers and fiber optic transmission contributing to a smaller share. The power consumption of a single radio access can be divided into two parts: the dynamic part includes only the power consumption when data is being sent or received; the static part includes the power consumption required to maintain the necessary operations of the radio access equipment at all times, including when no data is being sent or received.

[0059] Therefore, based on the above objectives, it is necessary to research and develop network energy consumption models, KPIs (Key Performance Indicators), and evaluation methods on the network device side to determine and study network energy-saving technologies in the target deployment scenario. Among them, the power consumption model on the terminal device side that has been defined can be used as a reference. This research should focus on how to achieve more efficient dynamic operation and / or semi-static operation, and consider one or more network energy-saving technologies applied to the time domain, frequency domain, spatial domain, and power domain, combined with potential terminal device feedback support, potential terminal device auxiliary information, and information exchange or coordination between network interfaces to achieve more fine-grained data transmission and / or reception adaptation.

[0060] It is worth noting that this study not only evaluates potential network energy savings but also assesses and balances the impact on network and user performance by observing key performance indicators (KPIs) such as spectrum efficiency, capacity, user perceived throughput (UPT), latency, UE power consumption, complexity, handover performance, call drop rate, initial access performance, and SLA security-related KPIs. This study should avoid significantly impacting these KPIs.

[0061] 2. Cell DTX and / or cell DRX configuration in NR systems

[0062] In the NR system, in order to achieve network energy saving, the network device can configure cell DTX and / or cell DRX configuration for the terminal device. During the inactive period of cell DTX configured for the terminal device, the network device may not send specific downlink channels or signals, and / or the terminal device may not receive specific downlink channels or signals. During the inactive period of cell DRX configured for the terminal device, the terminal device may not send specific downlink channels or signals, and / or the network device may not receive specific uplink channels or signals. In this way, energy consumption of the network device can be saved.

[0063] Currently, network equipment can configure cell DTX and cell DRX independently or simultaneously. The configuration of cell DTX and / or cell DRX can be enabled through RRC (Radio Resource Control) signaling, and can also be activated or deactivated through DCI (Downlink Control Information) signaling.

[0064] When the configuration of cell DTX and / or cell DRX is activated or deactivated through DCI signaling, if the terminal device receives DCI format 2_9 indicating a change in the activation or deactivation status of the cell DTX and / or cell DRX of the second cell on the time slot m on the downlink activation BWP (Bandwidth Part) of the first cell, then the terminal device activates or deactivates the cell DTX and / or cell DRX starting from the first time slot on the downlink activation BWP and / or uplink activation BWP of the second cell according to the indication information, wherein the first time slot is no earlier than the starting position of the time slot m+d on the downlink activation BWP of the first cell, and d is the number of time slots determined according to the subcarrier spacing of the downlink activation BWP of the first cell, and the values ​​are shown in Table 1 below.

[0065] Table 1: Values ​​of d

[0066] As an example, the second cell of the terminal device is configured with cell DRX and is in an unactivated state. When the terminal device receives a first DCI corresponding to DCI format 2_9 on time slot m1 on the downlink activation BWP of the first cell, and the first DCI indicates that the cell DRX of the second cell is activated, the terminal device activates the cell DRX starting from the first time slot on the uplink activation BWP of the second cell according to the indication information, wherein the first time slot is no earlier than the starting position of time slot m1+d on the downlink activation BWP of the first cell; when the terminal device receives a second DCI corresponding to DCI format 2_9 on time slot m2 on the downlink activation BWP of the first cell, and the second DCI indicates that the cell DRX of the second cell is deactivated, the terminal device deactivates the cell DRX starting from the second time slot on the uplink activation BWP of the second cell according to the indication information, wherein the second time slot is no earlier than the starting position of time slot m2+d on the downlink activation BWP of the first cell. Figure 4 shows a schematic diagram of the above-mentioned activation or deactivation of the cell DRX of the second cell through DCI signaling. In Figure 4 , it is assumed that the SCS (Subcarrier Spacing) of the downlink activated BWP of the first cell is 30 kHz, that is, the value of d is 6; and the SCS of the uplink activated BWP of the second cell is 15 kHz. It should be noted that the first cell and the second cell can be the same cell or different cells.

[0067] Please refer to Figure 5, which shows a flowchart of a wireless communication method provided by an embodiment of the present application. The method can be executed by a terminal device. The method may include the following steps:

[0068] In step 510, the first uplink transmission of the terminal device occupies the first time domain resource, and the second time domain resource is the overlapping part of the first time domain resource and the time domain resource of the non-activation period of the cell DRX. The first time domain resource includes the first target time domain resource and / or the second target time domain resource. The terminal device sends the first uplink transmission on the first target time domain resource, and / or does not send the first uplink transmission on the second target time domain resource.

[0069] In some embodiments, the first uplink transmission includes a preconfigured uplink channel or signal. In some embodiments, the preconfigured uplink channel or signal includes one or more of the following: CG-PUSCH (Configured Grant Physical Uplink Shared Channel), RRC-configured SRS (Sounding Reference Signal), MAC CE (Media Access Control Control Element)-activated SRS, SR (Scheduling Request), PUCCH (Physical Uplink Control Channel) without HARQ-ACK (Hybrid Automatic Repeat request-Acknowledgement) information, and PUSCH (Physical Uplink Shared Channel) carrying SP-CSI (Semi-Persistent Channel State Information).

[0070] In some embodiments, the first uplink transmission includes one or more preconfigured uplink channels or signals.

[0071] In some embodiments, when the first uplink transmission includes multiple preconfigured uplink channels or signals, the multiple preconfigured uplink channels or signals are repeatedly transmitted, or the multiple preconfigured uplink channels or signals are not repeatedly transmitted.

[0072] For example, when the preconfigured uplink channel or signal includes CG-PUSCH, the first uplink transmission includes one CG-PUSCH; or, the first uplink transmission includes multiple CG-PUSCHs carrying the same TB (Transport Block); or, the first uplink transmission includes multiple CG-PUSCHs carrying different TBs.

[0073] For example, when the preconfigured uplink channel or signal includes an SRS, the first uplink transmission includes one or more SRSs.

[0074] For example, when the preconfigured uplink channel or signal includes a PUCCH, the first uplink transmission includes one PUCCH; or, the first uplink transmission includes a plurality of repeatedly transmitted PUCCHs.

[0075] In some embodiments, the first uplink transmission includes a dynamically scheduled uplink channel or signal. In some embodiments, the dynamically scheduled uplink channel or signal includes one or more of the following: a DCI-scheduled PUSCH, a DCI-triggered SRS, or a PUCCH carrying HARQ-ACK information.

[0076] In some embodiments, when the first uplink transmission includes multiple dynamically scheduled uplink channels or signals, the multiple dynamically scheduled uplink channels or signals are repeatedly transmitted, or the multiple dynamically scheduled uplink channels or signals are not repeatedly transmitted.

[0077] In some embodiments, the activation period and inactivation period of the cell DRX are arranged at intervals. During the inactivation period of the cell DRX configured for the terminal device, the terminal device may not transmit a specific uplink channel or signal, and / or the network device may not receive a specific uplink channel or signal.

[0078] Normally, during the inactive period of the cell DRX, the terminal device does not send the pre-configured uplink channel or signal, and the network device does not receive the pre-configured uplink channel or signal. Since the dynamically scheduled uplink channel or signal is dynamically determined by the network device based on the service transmission demand, if the network device does not expect the terminal device to transmit during the inactive period of the cell DRX, scheduling may not be performed. Therefore, if the network device dynamically schedules the terminal device to send the uplink channel or signal during the inactive period of the cell DRX, the terminal device needs to send the dynamically scheduled uplink channel or signal, and accordingly, the network device can receive the dynamically scheduled uplink channel or signal. In addition, during the inactive period of the cell DRX, if the terminal device needs to provide HARQ-ACK information feedback for the received downlink channel or signal, the terminal device needs to send the HARQ-ACK information.

[0079] In an embodiment of the present application, the first uplink transmission of the terminal device occupies the first time domain resource, and the second time domain resource in the first time domain resource is the portion where the first time domain resource overlaps with the time domain resource of the non-activation period of the cell DRX. When the size of the second time domain resource is not 0 (that is, when the second time domain resource exists), it indicates that the time domain resource occupied by the first uplink transmission of the terminal device overlaps partially or completely with the time domain resource of the non-activation period of the cell DRX. When the size of the second time domain resource is 0 (that is, when the second time domain resource does not exist), it indicates that the first time domain resource occupied by the first uplink transmission of the terminal device does not belong to the non-activation period of the cell DRX.

[0080] The positional relationship between the first time domain resource and the second time domain resource includes one of the following situations.

[0081] Case 1: The starting position of the first time domain resource is within the activation period of the cell DRX, and the ending position of the first time domain resource is the same as the ending position of the second time domain resource.

[0082] Case 2: The starting position of the first time domain resource is within the activation period of the cell DRX, and the ending position of the first time domain resource is within the activation period of the cell DRX.

[0083] Case 3: the starting position of the first time domain resource is the same as the starting position of the second time domain resource, and the ending position of the first time domain resource is the same as the ending position of the second time domain resource.

[0084] Case 4: The starting position of the first time domain resource is the same as the starting position of the second time domain resource, and the ending position of the first time domain resource is within the activation period of the cell DRX.

[0085] As shown in FIG6 , it shows a schematic diagram of the positional relationship between the first time domain resource and the second time domain resource.

[0086] For case 1, the starting position of the first time domain resource is t1, the ending position of the first time domain resource is t4, the starting position of the second time domain resource is t2, and the ending position of the second time domain resource is t4. It can be seen that the starting position of the first time domain resource is within the activation period of the cell DRX, and the ending position of the first time domain resource is the same as the ending position of the second time domain resource.

[0087] For case 2, the starting position of the first time domain resource is t1, the ending position of the first time domain resource is t8, the starting position of the second time domain resource is t2, and the ending position of the second time domain resource is t7. It can be seen that the starting position of the first time domain resource is within the activation period of the cell DRX, and the ending position of the first time domain resource is within another activation period of the cell DRX.

[0088] For case 3, the starting position of the first time domain resource is t3, the ending position of the first time domain resource is t5, the starting position of the second time domain resource is t3, and the ending position of the second time domain resource is t5. It can be seen that the starting position of the first time domain resource is the same as the starting position of the second time domain resource, and the ending position of the first time domain resource is the same as the ending position of the second time domain resource.

[0089] For case 4, the starting position of the first time domain resource is t6, the ending position of the first time domain resource is t9, the starting position of the second time domain resource is t6, and the ending position of the second time domain resource is t7. It can be seen that the starting position of the first time domain resource is the same as the starting position of the second time domain resource, and the ending position of the first time domain resource is within the activation period of the cell DRX.

[0090] The following describes the behavior of the terminal device for two cases: a first uplink transmission includes a preconfigured uplink channel or signal; and a first uplink transmission includes a dynamically scheduled uplink channel or signal.

[0091] (1) The first uplink transmission includes a preconfigured uplink channel or signal.

[0092] When the first uplink transmission includes a preconfigured uplink channel or signal, the terminal device does not send the first uplink transmission on the second target time domain resource, including: the terminal device does not send the first uplink transmission on the second time domain resource, wherein the second target time domain resource includes the second time domain resource. That is, regardless of which of the above situations 1 to 4 the positional relationship between the first time domain resource and the second time domain resource is, when the first uplink transmission includes a preconfigured uplink channel or signal, the terminal device does not send the first uplink transmission on the second time domain resource.

[0093] In some embodiments, a terminal device does not send a first uplink transmission on a first time domain resource, wherein the second target time domain resource includes the first time domain resource. In this case, the terminal device does not send a first uplink transmission on the second time domain resource, including: the terminal device does not send a first uplink transmission on the first time domain resource. In other words, as long as some resources in the first time domain resource fall within an inactive period of cell DRX, the terminal device does not send a first uplink transmission on the first time domain resource.

[0094] In some embodiments, the terminal device sends a first uplink transmission on a time domain resource other than the second time domain resource in the first time domain resources, wherein the first target time domain resource includes the time domain resource other than the second time domain resource in the first time domain resources. In other words, the terminal device does not send the first uplink transmission on a time domain resource in the first time domain resources that is within an inactive period of cell DRX, and sends the first uplink transmission on a time domain resource in the first time domain resources that is not within an inactive period of cell DRX.

[0095] In some embodiments, the terminal device sends a first uplink transmission on a time domain resource located before the second time domain resource in the first time domain resource, and does not send the first uplink transmission on a time domain resource located after the second time domain resource in the first time domain resource, wherein the first target time domain resource includes the time domain resource located before the second time domain resource in the first time domain resource, and the second target time domain resource includes the time domain resource located after the second time domain resource in the first time domain resource. For example, in case 1, the terminal device sends a first uplink transmission on a time domain resource within the activation period of the cell DRX (i.e., the time domain resource from t1 to t2) in the first time domain resource. In case 2, the terminal device sends a first uplink transmission on a time domain resource within the activation period of the previous cell DRX (i.e., the time domain resource from t1 to t2) in the first time domain resource, and does not send the first uplink transmission on a time domain resource within the activation period of the next cell DRX (i.e., the time domain resource from t7 to t8) in the first time domain resource. In case 4, the terminal device does not send the first uplink transmission on the time domain resources in the first time domain resources that are within the activation period of the cell DRX (i.e., the time domain resources from t7 to t9). That is, if the time domain resources in the first time domain resources that are not within the inactive period of the cell DRX are located at the beginning of the first time domain resources, the terminal device sends the first uplink transmission; if the time domain resources in the first time domain resources that are not within the inactive period of the cell DRX are located at the end of the first time domain resources, the terminal device does not send the first uplink transmission.

[0096] In some embodiments, the terminal device does not send the first uplink transmission on the time domain resource located before the second time domain resource in the first time domain resource, and sends the first uplink transmission on the time domain resource located after the second time domain resource in the first time domain resource, wherein the first target time domain resource includes the time domain resource located after the second time domain resource in the first time domain resource, and the second target time domain resource includes the time domain resource located before the second time domain resource in the first time domain resource. For example, in case 1, the terminal device does not send the first uplink transmission on the time domain resource in the first time domain resource that belongs to the activation period of the cell DRX (i.e., the time domain resource from t1 to t2). In case 2, the terminal device does not send the first uplink transmission on the time domain resource in the first time domain resource that belongs to the activation period of the previous cell DRX (i.e., the time domain resource from t1 to t2), and sends the first uplink transmission on the time domain resource in the first time domain resource that belongs to the activation period of the next cell DRX (i.e., the time domain resource from t7 to t8). In case 4, the terminal device sends the first uplink transmission on a time domain resource in the first time domain resource that is within the activation period of the cell DRX (i.e., the time domain resource from t7 to t9). That is, if the time domain resource in the first time domain resource that is not within the inactive period of the cell DRX is located at the beginning of the first time domain resource, the terminal device does not send the first uplink transmission; if the time domain resource in the first time domain resource that is not within the inactive period of the cell DRX is located at the end of the first time domain resource, the terminal device sends the first uplink transmission.

[0097] In some embodiments, when the first uplink transmission includes a preconfigured uplink channel or signal, the terminal device sends the first uplink transmission on the first target time domain resource, including: in the absence of the second time domain resource, the terminal device sends the first uplink transmission on the first time domain resource, wherein the first target time domain resource includes the first time domain resource. In other words, as long as the first time domain resource does not belong to the inactive period of cell DRX, the terminal device must send the first uplink transmission on the first time domain resource.

[0098] In some embodiments, the time domain resources that do not belong to the non-activation period of cell DRX include at least one of the following situations: time domain resources that belong to the activation period of cell DRX, and time domain resources when there is no cell DRX (for example, time domain resources after the cell DRX is deactivated).

[0099] In some embodiments, the terminal device does not send the first uplink transmission, including at least one of the following situations: the terminal device cancels sending the first uplink transmission, and the terminal device does not prepare the first uplink transmission.

[0100] (2) The first uplink transmission includes a dynamically scheduled uplink channel or signal.

[0101] When the first uplink transmission includes a dynamically scheduled uplink channel or signal, the terminal device sends the first uplink transmission on the first target time domain resource, including: the terminal device sends the first uplink transmission on the first time domain resource; wherein the first target time domain resource includes the first time domain resource. That is, regardless of which of the above situations 1 to 4 the positional relationship between the first time domain resource and the second time domain resource is, when the first uplink transmission includes a dynamically scheduled uplink channel or signal, the terminal device sends the first uplink transmission.

[0102] It should be understood that in the relevant technology, if the PUCCH carrying HARQ-ACK information and the pre-configured uplink channel or signal to be transmitted by the terminal device (such as CG-PUSCH or PUSCH carrying SP-CSI) collide in the time domain, then the terminal device can multiplex the HARQ-ACK information on the CG-PUSCH or the PUSCH carrying SP-CSI for transmission, that is, the terminal device only transmits the PUSCH, wherein the PUSCH carries the HARQ-ACK information. Since the terminal device needs to send the PUCCH carrying the HARQ-ACK information during the inactive period of the cell DRX but does not expect the terminal device to send the pre-configured uplink channel or signal (such as CG-PUSCH or PUSCH carrying SP-CSI), when the PUCCH carrying the HARQ-ACK information and the CG-PUSCH to be transmitted by the terminal device or the PUSCH carrying SP-CSI collide on the time domain resources within the inactive period of the cell DRX, the behavior of the terminal device needs to be specified.

[0103] For the situation where the first uplink transmission includes a pre-configured PUSCH (such as CG-PUSCH or PUSCH carrying SP-CSI) and a PUCCH carrying HARQ-ACK information that overlap in the time domain, the terminal device sends the first uplink transmission on the first target time domain resource, including one of the following situations a to h.

[0104] Case a: The terminal device transmits PUCCH carrying HARQ-ACK information.

[0105] Case b: The terminal device transmits a pre-configured PUSCH, which carries HARQ-ACK information.

[0106] Case c: When it is determined according to the first configuration information that the HARQ-ACK information and the pre-configured PUSCH are not multiplexed, the terminal device transmits the PUCCH carrying the HARQ-ACK information.

[0107] Case d: When the HARQ-ACK information and the pre-configured PUSCH are multiplexed according to the first configuration information, the terminal device transmits the pre-configured PUSCH, which carries the HARQ-ACK information.

[0108] Case e: When the inactive period of the cell DRX is determined by the DCI format, or when the DCI format is used to activate or deactivate the cell DRX according to the second configuration information, the terminal device transmits a PUCCH carrying HARQ-ACK information.

[0109] Case f: When the inactive period of the cell DRX is determined by the DCI format, or when the DCI format is used to activate or deactivate the cell DRX according to the second configuration information, the terminal device transmits a pre-configured PUSCH carrying HARQ-ACK information.

[0110] Case g: When the inactive period of the cell DRX is determined by RRC signaling, or when it is determined based on the third configuration information that the cell DRX is configured using RRC signaling, the terminal device transmits a PUCCH carrying HARQ-ACK information.

[0111] Case h: When the inactive period of the cell DRX is determined by RRC signaling, or when it is determined based on the third configuration information that the cell DRX is configured using RRC signaling, the terminal device transmits a pre-configured PUSCH, which carries HARQ-ACK information.

[0112] In some embodiments, the pre-configured PUSCH includes a CG-PUSCH or a PUSCH carrying SP-CSI.

[0113] In some embodiments, the terminal device transmits a PUCCH carrying HARQ-ACK information, including: if the pre-configured PUSCH and the PUCCH carrying HARQ-ACK information overlap on a third time domain resource, when the third time domain resource and the second time domain resource partially overlap or completely overlap, the terminal device transmits the PUCCH carrying HARQ-ACK information on the third time domain resource. Alternatively, if the pre-configured PUSCH and the PUCCH carrying HARQ-ACK information overlap on a third time domain resource, when the third time domain resource and the second time domain resource do not overlap at all, the terminal device transmits the PUCCH carrying HARQ-ACK information on the third time domain resource. Wherein, the first target time domain resource includes the third time domain resource.

[0114] In some embodiments, when the first uplink transmission includes a pre-configured PUSCH and a PUCCH carrying HARQ-ACK information, the terminal device transmits the PUCCH carrying the HARQ-ACK information and does not transmit the pre-configured PUSCH.

[0115] In some embodiments, when the first uplink transmission includes a pre-configured PUSCH and a PUCCH carrying HARQ-ACK information, if the pre-configured PUSCH and the PUCCH carrying HARQ-ACK information overlap on a third time domain resource, when the third time domain resource and the second time domain resource partially overlap or completely overlap, the terminal device transmits the PUCCH carrying HARQ-ACK information on the third time domain resource, and / or the terminal device does not transmit the pre-configured PUSCH. The fact that the terminal device does not transmit the pre-configured PUSCH may mean that the terminal device does not transmit the pre-configured PUSCH on the third time domain resource, or does not transmit the pre-configured PUSCH on the second time domain resource, or does not transmit the pre-configured PUSCH on the first time domain resource.

[0116] In some embodiments, when the first uplink transmission includes a pre-configured PUSCH and a PUCCH carrying HARQ-ACK information, if the pre-configured PUSCH and the PUCCH carrying HARQ-ACK information overlap on a third time domain resource, when the third time domain resource and the second time domain resource do not overlap at all, the terminal device transmits the PUCCH carrying HARQ-ACK information on the third time domain resource, and / or the terminal device does not transmit the pre-configured PUSCH. That is, in this case, as long as the PUCCH carrying HARQ-ACK information and the pre-configured PUSCH overlap in the time domain, the terminal device does not transmit the pre-configured PUSCH. Among them, the terminal device does not transmit the pre-configured PUSCH, which may be that the terminal device does not transmit the pre-configured PUSCH on the third time domain resource, or does not transmit the pre-configured PUSCH on the second time domain resource, or does not transmit the pre-configured PUSCH on the first time domain resource.

[0117] In some embodiments, when the first uplink transmission includes a pre-configured PUSCH and a PUCCH carrying HARQ-ACK information, if the pre-configured PUSCH and the PUCCH carrying HARQ-ACK information overlap on a third time domain resource, when the third time domain resource and the second time domain resource do not overlap at all, the terminal device transmits the pre-configured PUSCH carrying HARQ-ACK information on the third time domain resource, and / or the terminal device does not transmit the pre-configured PUSCH on the second time domain resource. That is, in this case, if the pre-configured PUSCH and the PUCCH carrying HARQ-ACK information do not overlap on the time domain resources of the inactive period of the cell DRX, the terminal device still multiplexes the HARQ-ACK information onto the pre-configured PUSCH for transmission.

[0118] In some embodiments, the terminal device transmits a preconfigured PUSCH, which carries HARQ-ACK information, including: if the preconfigured PUSCH and the PUCCH carrying the HARQ-ACK information overlap on a third time domain resource, when the third time domain resource and the second time domain resource partially overlap or completely overlap, the terminal device transmits the preconfigured PUSCH carrying the HARQ-ACK information on the third time domain resource. Alternatively, if the preconfigured PUSCH and the PUCCH carrying the HARQ-ACK information overlap on a third time domain resource, when the third time domain resource and the second time domain resource do not overlap at all, the terminal device transmits the preconfigured PUSCH carrying the HARQ-ACK information on the third time domain resource. Wherein, the first target time domain resource includes the third time domain resource.

[0119] In some embodiments, when the first uplink transmission includes a pre-configured PUSCH and a PUCCH carrying HARQ-ACK information, the terminal device transmits the pre-configured PUSCH, which carries the HARQ-ACK information.

[0120] In some embodiments, when the first uplink transmission includes a pre-configured PUSCH and a PUCCH carrying HARQ-ACK information, if the pre-configured PUSCH and the PUCCH carrying HARQ-ACK information overlap on a third time domain resource, when the third time domain resource and the second time domain resource partially overlap or fully overlap, the terminal device transmits the pre-configured PUSCH carrying HARQ-ACK information on the third time domain resource, and / or the terminal device does not transmit the pre-configured PUSCH on time domain resources in the second time domain resource other than the third time domain resource.

[0121] In some embodiments, when the first uplink transmission includes a preconfigured PUSCH and a PUCCH carrying HARQ-ACK information, if the preconfigured PUSCH and the PUCCH carrying HARQ-ACK information overlap on a third time domain resource, when the third time domain resource and the second time domain resource do not overlap at all, the terminal device transmits the preconfigured PUSCH carrying HARQ-ACK information on the third time domain resource, and / or the terminal device does not transmit the preconfigured PUSCH on the second time domain resource.

[0122] In some embodiments, when the first uplink transmission includes a pre-configured PUSCH and a PUCCH carrying HARQ-ACK information, the behavior of the terminal device is determined according to the first configuration information. In some embodiments, the first configuration information is used to configure whether the HARQ-ACK information and the pre-configured PUSCH are multiplexed during the non-activation period of the cell DRX. In some embodiments, when it is determined according to the first configuration information that the HARQ-ACK information and the pre-configured PUSCH are not multiplexed, the terminal device transmits the PUCCH carrying the HARQ-ACK information and does not transmit the pre-configured PUSCH. In some embodiments, when it is determined according to the first configuration information that the HARQ-ACK information and the pre-configured PUSCH are multiplexed, the terminal device transmits the pre-configured PUSCH, which carries the HARQ-ACK information.

[0123] In some embodiments, when the first uplink transmission includes a pre-configured PUSCH and a PUCCH carrying HARQ-ACK information (when the PUCCH carrying HARQ-ACK information and the pre-configured PUSCH to be transmitted by the terminal device collide on time domain resources within the non-activation period of the cell DRX), if the non-activation period of the cell DRX is determined by RRC signaling (or the cell DRX is configured using RRC signaling according to the third configuration information), the terminal device transmits the PUCCH carrying the HARQ-ACK information and does not transmit the pre-configured PUSCH; and / or, if the non-activation period of the cell DRX is determined by the first DCI format (or the cell DRX is activated or deactivated using the DCI format according to the second configuration information), the terminal device transmits the pre-configured PUSCH, which carries the HARQ-ACK information.

[0124] In some embodiments, the first DCI format is DCI format 2_9.

[0125] That is to say, when the inactive period of cell DRX is determined by RRC signaling, if the PUCCH carrying HARQ-ACK information and the pre-configured PUSCH to be transmitted by the terminal device collide on time domain resources within the inactive period of cell DRX, the terminal device transmits the PUCCH carrying HARQ-ACK information and does not transmit the pre-configured PUSCH. When the inactive period of cell DRX is determined by DCI signaling, if the PUCCH carrying HARQ-ACK information and the pre-configured PUSCH to be transmitted by the terminal device collide on time domain resources within the inactive period of cell DRX, the terminal device transmits the pre-configured PUSCH carrying HARQ-ACK information. This is mainly because the terminal device has a certain bit error rate when monitoring the DCI format, that is, the terminal device may not receive the DCI format for activating or deactivating the cell DRX, and may therefore have a misunderstanding of the cell's inactive period. In order to avoid the impact on the transmission of HARQ-ACK information and pre-configured PUSCH due to a misunderstanding of the cell's inactive period, the behavior of the terminal device can be specified, for example, always transmitting the pre-configured PUSCH carrying HARQ-ACK information or always transmitting the PUCCH carrying HARQ-ACK information.

[0126] Through the above method, when the non-activation period of cell DRX is determined by DCI signaling, when the PUCCH carrying HARQ-ACK information and the pre-configured PUSCH to be transmitted by the terminal device collide on the time domain resources within the non-activation period of cell DRX, it is stipulated that the HARQ-ACK information is always multiplexed to the pre-configured PUSCH for transmission or the PUCCH carrying HARQ-ACK information is always transmitted, which can avoid inconsistent understanding of the uplink channel or signal to be transmitted by the network device and the terminal device.

[0127] In some embodiments, when the first uplink transmission includes a pre-configured PUSCH and a PUCCH carrying HARQ-ACK information (when the PUCCH carrying HARQ-ACK information and the pre-configured PUSCH to be transmitted by the terminal device collide on time domain resources within the inactive period of the cell DRX), if the inactive period of the cell DRX is determined by RRC signaling (or the cell DRX is configured using RRC signaling according to the third configuration information), the terminal device transmits the pre-configured PUSCH, which carries the HARQ-ACK information; and / or, if the inactive period of the cell DRX is determined by the first DCI format (or the cell DRX is activated or deactivated using the DCI format according to the second configuration information), the terminal device transmits the PUCCH carrying the HARQ-ACK information, and does not transmit the pre-configured PUSCH.

[0128] In some embodiments, when the terminal device is configured with DCI format to activate or deactivate cell DRX, if the first uplink transmission includes a pre-configured PUSCH and a PUCCH carrying HARQ-ACK information, the terminal device transmits the PUCCH carrying the HARQ-ACK information and does not transmit the pre-configured PUSCH.

[0129] In some embodiments, if the terminal device is configured with a DCI format to activate or deactivate cell DRX, when the pre-configured PUSCH and the PUCCH carrying HARQ-ACK information overlap in the time domain, the terminal device always does not consider the multiplexing of the pre-configured PUSCH and the PUCCH carrying HARQ-ACK information, that is, the terminal device always transmits the PUCCH carrying HARQ-ACK information. For example, if the terminal device is configured with a DCI format to activate or deactivate cell DRX, when the CG-PUSCH or the PUSCH carrying SP-CSI and the PUCCH carrying HARQ-ACK information overlap on time domain resources within the inactive period of cell DRX, the terminal device transmits the PUCCH carrying HARQ-ACK information; when the CG-PUSCH or the PUSCH carrying SP-CSI and the PUCCH carrying HARQ-ACK information overlap on time domain resources within the active period of cell DRX, the terminal device still transmits the PUCCH carrying HARQ-ACK information.

[0130] In some embodiments, if the cell DRX is configured by RRC signaling, when the pre-configured PUSCH and the PUCCH carrying HARQ-ACK information overlap in the time domain within the inactive period of the cell DRX, the terminal device does not consider the multiplexing of the pre-configured PUSCH and the PUCCH carrying the HARQ-ACK information, that is, the terminal device transmits the PUCCH carrying the HARQ-ACK information during the inactive period of the cell DRX. For example, if the cell DRX is configured by RRC signaling, when the CG-PUSCH or the PUSCH carrying SP-CSI and the PUCCH carrying HARQ-ACK information overlap in the time domain resources within the inactive period of the cell DRX, the terminal device transmits the PUCCH carrying the HARQ-ACK information; or when the CG-PUSCH or the PUSCH carrying SP-CSI and the PUCCH carrying the HARQ-ACK information overlap in the time domain resources within the active period of the cell DRX, the terminal device transmits the PUSCH carrying the HARQ-ACK information.

[0131] It should be understood that a certain amount of processing time is required for the terminal device to prepare to send the first uplink transmission or cancel the sending of the first uplink transmission. After the terminal device has begun to prepare to send the first uplink transmission, if it receives a signaling instructing to cancel the first uplink transmission, the terminal device cannot cancel the first uplink transmission. Alternatively, if the terminal device receives a signaling instructing to send the first uplink transmission, but the time from the moment the signaling is received to the time the first uplink transmission is sent is less than the processing time, the terminal device will also be unable to send the first uplink transmission because it will not have enough time to prepare.

[0132] In some embodiments of the present application, whether the terminal device sends the first uplink transmission needs to be judged based on the overlap between the first time domain resources occupied by the first uplink transmission and the time domain resources of the inactive period of the cell DRX. When the inactive period of the cell DRX is determined by the first DCI format, in addition to considering the impact of the inactive period of the cell DRX, the impact of the processing time of the terminal device to cancel the first uplink transmission and / or the processing time to prepare for the first uplink transmission must also be considered. In other words, the aforementioned behavior of the terminal device to send or not send the first uplink transmission also needs to be affected by the first condition and / or the second condition.

[0133] In some embodiments, the terminal device sends a first uplink transmission on a first target time domain resource, including: when a first condition is met, the terminal device sends the first uplink transmission on the first target time domain resource; and / or, when the first condition is not met, the terminal device does not send the first uplink transmission on the first target time domain resource.

[0134] In some embodiments, some time domain resources in the first target time domain resources do not belong to the cell DRX inactive period.

[0135] In some embodiments, all time domain resources in the first target time domain resources do not belong to the cell DRX inactive period.

[0136] In some embodiments, the first condition includes a condition related to a first processing time length. As an example, the first processing time length refers to a processing time length for the terminal device to prepare for the first uplink transmission.

[0137] In some embodiments, the terminal device sends a first uplink transmission on a first target time domain resource, including: the terminal device sends at least a portion of the first uplink transmission on the first target time domain resource.

[0138] In some embodiments, when the inactive period of cell DRX is determined by a first DCI format, if a first condition is met, the terminal device sends a first uplink transmission on a first target time domain resource; and / or, if the first condition is not met, the terminal device does not send a first uplink transmission on the first target time domain resource, wherein the first target time domain resource does not belong to the inactive period of cell DRX.

[0139] In some embodiments, the first target time domain resource includes the time domain resource determined to be used to send the first uplink transmission in the aforementioned embodiment.

[0140] In some embodiments, the first target time domain resource includes at least one of the following situations:

[0141] First time domain resources;

[0142] time domain resources in the first time domain resources except the second time domain resources;

[0143] A time domain resource located before the second time domain resource in the first time domain resource;

[0144] A time domain resource in the first time domain resource that is located after the second time domain resource.

[0145] For example, the first target time domain resource includes the first time domain resource, and the terminal device sends the first uplink transmission on the first time domain resource, including: when the first condition is met, the terminal device sends the first uplink transmission on the first time domain resource; and / or, when the first condition is not met, the terminal device does not send the first uplink transmission on the first time domain resource.

[0146] For another example, the first target time domain resources include the time domain resources in the first time domain resources except the second time domain resources, and the terminal device sends the first uplink transmission on the time domain resources in the first time domain resources except the second time domain resources, including: when the first condition is met, the terminal device sends the first uplink transmission on the time domain resources in the first time domain resources except the second time domain resources; and / or, when the first condition is not met, the terminal device does not send the first uplink transmission on the time domain resources in the first time domain resources except the second time domain resources.

[0147] For another example, the first target time domain resource includes a time domain resource in the first time domain resource that is located before the second time domain resource, and the terminal device sends a first uplink transmission on a time domain resource in the first time domain resource that is located before the second time domain resource, including: when the first condition is met, the terminal device sends the first uplink transmission on the time domain resource in the first time domain resource that is located before the second time domain resource; and / or, when the first condition is not met, the terminal device does not send the first uplink transmission on the time domain resource in the first time domain resource that is located before the second time domain resource.

[0148] For another example, the first target time domain resource includes a time domain resource in the first time domain resource that is located behind the second time domain resource, and the terminal device sends a first uplink transmission on a time domain resource in the first time domain resource that is located behind the second time domain resource, including: when the first condition is met, the terminal device sends the first uplink transmission on the time domain resource in the first time domain resource that is located behind the second time domain resource; and / or, when the first condition is not met, the terminal device does not send the first uplink transmission on the time domain resource in the first time domain resource that is located behind the second time domain resource.

[0149] In some embodiments, the first processing time length condition refers to a condition related to the first processing time length. Meeting the first condition includes meeting the first processing time length condition, and / or, not meeting the first condition includes not meeting the first processing time length condition. When the first condition is met, the terminal device sends the first uplink transmission on the first target time domain resource; and / or, when the first condition is not met, the terminal device does not send the first uplink transmission on the first target time domain resource, which can be replaced by: when the first processing time length condition is met, the terminal device sends the first uplink transmission on the first target time domain resource; and / or, when the first processing time length condition is not met, the terminal device does not send the first uplink transmission on the first target time domain resource.

[0150] In some embodiments, the first condition (or the first processing time length condition) includes: the interval length between the first time domain position and the starting position of the first target time domain resource is greater than or equal to the first processing time length. In this case, satisfying the first processing time length condition includes: the interval length between the first time domain position and the starting position of the first target time domain resource is greater than or equal to the first processing time length; and / or not satisfying the first processing time length condition includes: the interval length between the first time domain position and the starting position of the first target time domain resource is less than the first processing time length.

[0151] In some embodiments, the first condition (or the first processing time length condition) includes: the interval length between the first time domain position and the starting position of the first time domain resource is greater than or equal to the first processing time length. In this case, satisfying the first processing time length condition includes: the interval length between the first time domain position and the starting position of the first time domain resource is greater than or equal to the first processing time length; and / or not satisfying the first processing time length condition includes: the interval length between the first time domain position and the starting position of the first time domain resource is less than the first processing time length.

[0152] In some embodiments, the first time domain position includes one of the following situations:

[0153] The terminal device receives the last symbol received by the PDCCH (Physical Downlink Control Channel) carrying the first DCI format;

[0154] The end position of the time slot in which the last symbol received by the terminal device from the PDCCH carrying the first DCI format is located;

[0155] The terminal device is configured to receive the last symbol received by the PDCCH for transmitting the first DCI format; that is, the terminal device detects the last symbol of the CORESET (Control Resource Set) of the first DCI format;

[0156] The terminal device is configured to receive an end position of a time slot in which the last symbol received by the PDCCH for transmitting the first DCI format is located;

[0157] Determine the effective time of activating the cell DRX according to the first DCI format; for example, the starting time of the time slot m1+6 of the downlink activation BWP of the first cell in FIG4 ; or the starting time of the first time slot of the uplink activation BWP of the second cell in FIG4 ;

[0158] Determine the effective time of deactivating the cell DRX according to the first DCI format; for example, the start time of the time slot m2+6 of the downlink activation BWP of the first cell in FIG4 ; or the start time of the second time slot of the uplink activation BWP of the second cell in FIG4 ;

[0159] The effective time of the first DCI format; for example, the starting position of the time slot m+d on the downlink activation BWP of the first cell determined according to Table 1; or the starting position of the first time slot;

[0160] The first DCI format is used to indicate activation or deactivation of cell DRX, and / or the first DCI format is used to indicate that the cell enters a network energy-saving mode, for example, to indicate that the cell is shut down.

[0161] The following example is taken as an example that all the time domain resources in the first time domain resource do not belong to the non-activation period of the cell DRX. As shown in Figure 7, the first time domain resource is the time domain resource occupied by the uplink channel or signal pre-configured by the terminal device, which originally belongs to the non-activation period of the cell DRX, but the terminal device determines that the first time domain resource does not belong to the non-activation period of the cell DRX based on the received first DCI format for indicating the deactivation of the cell DRX. Therefore, the terminal device should send the first uplink transmission on the first time domain resource. In this case, the terminal device needs to determine whether to send the first uplink transmission based on whether the first processing time length condition is met between the first time domain position and the starting position of the first time domain resource. Specifically, when the first time domain position is within the first processing time length associated with the first time domain resource, the terminal device does not send the first uplink transmission; otherwise, the terminal device sends the first uplink transmission.

[0162] In some embodiments, the terminal device does not send the first uplink transmission on the second target time domain resource, including: when the second condition is met, the terminal device does not send the first uplink transmission on the second target time domain resource; and / or, when the second condition is not met, the terminal device sends the first uplink transmission on the second target time domain resource.

[0163] In some embodiments, some of the time domain resources in the second target time domain resources belong to a non-activation period of cell DRX.

[0164] In some embodiments, all time domain resources in the second target time domain resources belong to a non-activation period of cell DRX.

[0165] In some embodiments, the second condition includes a condition related to a second processing time length. As an example, the second processing time length refers to a processing time length for the terminal device to cancel the first uplink transmission.

[0166] In some embodiments, the terminal device does not send the first uplink transmission on the second target time domain resource, including: the terminal device does not send at least part of the first uplink transmission on the second target time domain resource.

[0167] In some embodiments, when the inactive period of cell DRX is determined by a first DCI format, if the second condition is met, the terminal device does not send the first uplink transmission on the second target time domain resource; and / or, if the second condition is not met, the terminal device sends the first uplink transmission on the second target time domain resource in the first time domain resource, wherein at least part of the time domain resources in the second target time domain resource belong to the inactive period of cell DRX.

[0168] In some embodiments, the second target time domain resource includes the time domain resource determined not to send the first uplink transmission in the aforementioned embodiment.

[0169] In some embodiments, the second target time domain resource includes at least one of the following situations:

[0170] Second time domain resources;

[0171] First time domain resources;

[0172] A time domain resource located before the second time domain resource in the first time domain resource;

[0173] A time domain resource in the first time domain resource that is located after the second time domain resource.

[0174] For example, the second target time domain resource includes the second time domain resource, and the terminal device does not send the first uplink transmission on the second time domain resource, including: when the second condition is met, the terminal device does not send the first uplink transmission on the second time domain resource; and / or, when the second condition is not met, the terminal device sends the first uplink transmission on the second time domain resource.

[0175] For another example, the second target time domain resource includes the first time domain resource, and the terminal device does not send the first uplink transmission on the first time domain resource, including: when the second condition is met, the terminal device does not send the first uplink transmission on the first time domain resource; and / or, when the second condition is not met, the terminal device sends the first uplink transmission on the first time domain resource.

[0176] For another example, the second target time domain resource includes a time domain resource in the first time domain resource that is located before the second time domain resource, and the terminal device does not send the first uplink transmission on the time domain resource in the first time domain resource that is located before the second time domain resource, including: when the second condition is met, the terminal device does not send the first uplink transmission on the time domain resource in the first time domain resource that is located before the second time domain resource; and / or, when the second condition is not met, the terminal device sends the first uplink transmission on the time domain resource in the first time domain resource that is located before the second time domain resource.

[0177] For another example, the second target time domain resource includes a time domain resource in the first time domain resource that is located behind the second time domain resource, and the terminal device does not send the first uplink transmission on the time domain resource in the first time domain resource that is located behind the second time domain resource, including: when the second condition is met, the terminal device does not send the first uplink transmission on the time domain resource in the first time domain resource that is located behind the second time domain resource; and / or, when the second condition is not met, the terminal device sends the first uplink transmission on the time domain resource in the first time domain resource that is located behind the second time domain resource.

[0178] In some embodiments, the second processing time length condition refers to a condition related to the second processing time length. Meeting the second condition includes meeting the second processing time length condition, and / or, not meeting the second condition includes not meeting the second processing time length condition. When the second condition is met, the terminal device does not send the first uplink transmission on the second target time domain resource; and / or, when the second condition is not met, the terminal device sends the first uplink transmission on the second target time domain resource, which can be replaced by: when the second processing time length condition is met, the terminal device does not send the first uplink transmission on the second target time domain resource; and / or, when the second processing time length condition is not met, the terminal device sends the first uplink transmission on the second target time domain resource.

[0179] In some embodiments, the second condition (or second processing time length condition) includes: the interval length between the second time domain position and the starting position of the second target time domain resource is greater than or equal to the second processing time length. In this case, satisfying the second processing time length condition includes: the interval length between the second time domain position and the starting position of the second target time domain resource is greater than or equal to the second processing time length; and / or not satisfying the second processing time length condition includes: the interval length between the second time domain position and the starting position of the second target time domain resource is less than the second processing time length.

[0180] In some embodiments, the second condition (or second processing time length condition) includes: the interval between the second time domain position and the starting position of the first time domain resource is greater than or equal to the second processing time length. In this case, satisfying the second processing time length condition includes: the interval between the second time domain position and the starting position of the first time domain resource is greater than or equal to the second processing time length; and / or not satisfying the second processing time length condition includes: the interval between the second time domain position and the starting position of the first time domain resource is less than the second processing time length.

[0181] In some embodiments, the second time domain position includes one of the following situations:

[0182] The terminal device receives the last symbol of the PDCCH carrying the first DCI format;

[0183] The end position of the time slot in which the last symbol received by the terminal device in the PDCCH carrying the first DCI format is located;

[0184] The terminal device is configured to receive the last symbol received by the PDCCH for transmitting the first DCI format; that is, the terminal device detects the last symbol of the CORESET of the first DCI format;

[0185] The terminal device is configured to receive an end position of a time slot in which the last symbol received by the PDCCH for transmitting the first DCI format is located;

[0186] Determine the effective time of activating the cell DRX according to the first DCI format; for example, the starting time of the time slot m1+6 of the downlink activation BWP of the first cell in FIG4 ; or the starting time of the first time slot of the uplink activation BWP of the second cell in FIG4 ;

[0187] Determine the effective time of deactivating the cell DRX according to the first DCI format; for example, the start time of the time slot m2+6 of the downlink activation BWP of the first cell in FIG4 ; or the start time of the second time slot of the uplink activation BWP of the second cell in FIG4 ;

[0188] The effective time of the first DCI format; for example, the starting position of the time slot m+d on the downlink activation BWP of the first cell determined according to Table 1; or the starting position of the first time slot;

[0189] The first DCI format is used to indicate activation or deactivation of cell DRX, and / or the first DCI format is used to indicate that the cell enters a network energy-saving mode, for example, to indicate that the cell is shut down.

[0190] In some embodiments, the second processing time length and the first processing time length may be the same processing time length or different processing time lengths, which is not limited in this application.

[0191] The following example is taken as an example that all the time domain resources in the first time domain resource belong to the non-activated period of the cell DRX. As shown in Figure 8, the first time domain resource is the time domain resource occupied by the uplink channel or signal pre-configured by the terminal device, which originally does not belong to the non-activated period of the cell DRX. However, the terminal device determines that the first time domain resource belongs to the non-activated period of the cell DRX based on the received first DCI format for indicating the activation of the cell DRX. Therefore, the terminal device should not send the first uplink transmission on the first time domain resource. In this case, the terminal device needs to determine whether to send the first uplink transmission based on whether the second processing time length condition is met between the second time domain position and the starting position of the first time domain resource. Specifically, when the second time domain position is within the second processing time length associated with the first time domain resource, the terminal device sends the first uplink transmission; otherwise, the terminal device does not send the first uplink transmission.

[0192] Another example is given below. The first time domain resource is time slot m, which is a resource that the terminal device is configured to use to transmit pre-configured PUSCH or PUCCH. Taking CG-PUSCH as an example, as shown in Figure 9, time slot m does not originally belong to the non-activated period of cell DRX. When the terminal device receives DCI format 2_9 for indicating the activation of cell DRX, and determines based on the DCI format 2_9 that time slot m belongs to the non-activated period of cell DRX, in principle, the terminal device cannot use time slot m to transmit CG-PUSCH. In this case, the terminal device needs to determine whether time slot m can be used to send CG-PUSCH based on whether the second processing time length (for example, Tpro,2 length) is met between the time domain position of the received DCI format 2_9 and the starting position of time slot m. When the time interval between the end position of the received DCI format 2_9 and the start position of time slot m is greater than or equal to the length Tpro,2, the terminal device does not send CG-PUSCH in time slot m; alternatively, if the terminal device has already started preparing to send CG-PUSCH in time slot m, when the time interval between the end position of the received DCI format 2_9 and the start position of time slot m is less than the length Tpro,2, the terminal device may send CG-PUSCH in time slot m. In some embodiments, the length Tpro,2 is determined based on the time interval required for the terminal device to switch BWP.

[0193] Another example is given below. The first time domain resource is time slot m, m+1, m+2, m+3, which is the resource that the terminal device is configured to use for repeated transmission of pre-configured PUSCH or PUCCH. In this example, it is assumed that if part or all of the resources in the first time domain resource overlap with the time domain resources of the non-activation period of the cell DRX, the terminal device should not transmit the pre-configured PUSCH or PUCCH through the first time domain resource. Taking CG-PUSCH as an example, as shown in Figure 10, the first time domain resource does not originally belong to the non-activation period of the cell DRX. When the terminal device receives the DCI format 2_9 for indicating the activation of the cell DRX, it can be determined based on the DCI format 2_9 that part of the resources in the first time domain resource belongs to the non-activation period of the cell DRX. That is, in principle, the terminal device should not transmit CG-PUSCH through the first time domain resource. In this case, the terminal device needs to determine whether the first time domain resource can be used to send CG-PUSCH based on whether the second processing time length (for example, Tpro,2 length) is met between the time domain position of the received DCI format 2_9 and the position of the first time domain resource. In case 1, the time interval between the end position of the received DCI format 2_9 and the start position of the first time domain resource is greater than or equal to the length of Tpro,2. In this case, the terminal device does not send CG-PUSCH on the first time domain resource. In case 2, the time interval between the end position of the received DCI format 2_9 and the start position of the first time domain resource is less than the length of Tpro,2. In this case, in an optional implementation, the terminal device may send CG-PUSCH on the first time domain resource, as shown in case 2-1 in Figure 10; in another optional implementation, the terminal device may send CG-PUSCH on a time slot that does not meet the length of Tpro,2 in the first time domain resource (i.e., slot m), and not send CG-PUSCH on a time slot that meets the length of Tpro,2 in the first time domain resource (i.e., slot m+1, m+2, m+3), as shown in case 2-2 in Figure 10.

[0194] The technical solution provided in the embodiment of the present application provides a solution for how to handle the uplink transmission when the terminal device is configured with cell DRX and the time domain resources occupied by the uplink transmission of the terminal device partially or completely overlap with the time domain resources occupied by the inactive period of the cell DRX. The terminal device can send the uplink transmission on certain time domain resources and / or not send the uplink transmission on certain time domain resources, thereby ensuring that the network device and the terminal device have a consistent understanding of the uplink channel or signal to be transmitted, thereby improving the reliability of the uplink transmission.

[0195] In addition, in the network energy-saving system, when the terminal device is configured with cell DRX, if the time domain resources occupied by the terminal device's uplink transmission (pre-configured uplink transmission and / or dynamically scheduled uplink transmission) partially or completely overlap with the time domain resources occupied by the non-activation period of the cell DRX, according to the method in the present application, the terminal device can send the uplink transmission or cancel the sending of the uplink transmission if the processing time condition is met, thereby eliminating the need to increase additional terminal device costs.

[0196] Please refer to Figure 11, which shows a flow chart of a wireless communication method provided by another embodiment of the present application. The method can be performed by a network device. The method may include the following steps:

[0197] In step 1110, the first uplink transmission of the terminal device occupies the first time domain resource, and the second time domain resource is the overlapping part of the first time domain resource and the time domain resource of the non-activation period of the cell DRX configured by the network device. The first time domain resource includes the first target time domain resource and / or the second target time domain resource. The network device receives the first uplink transmission on the first target time domain resource, and / or does not receive the first uplink transmission on the second target time domain resource.

[0198] In some embodiments, the first uplink transmission includes a preconfigured uplink channel or signal. For explanations of the preconfigured uplink channel or signal, please refer to the above embodiments and will not be repeated here.

[0199] In some embodiments, the first uplink transmission includes a dynamically scheduled uplink channel or signal. For explanations of the dynamically scheduled uplink channel or signal, please refer to the above embodiments and will not be repeated here.

[0200] The following describes the behavior of the network device for two cases: the first uplink transmission includes a pre-configured uplink channel or signal; and the first uplink transmission includes a dynamically scheduled uplink channel or signal.

[0201] (1) The first uplink transmission includes a preconfigured uplink channel or signal.

[0202] When the first uplink transmission includes a preconfigured uplink channel or signal, the network device does not receive the first uplink transmission on the second target time domain resource, including: the network device does not receive the first uplink transmission on the second time domain resource, wherein the second target time domain resource includes the second time domain resource. In other words, regardless of which of the above situations 1 to 4 the positional relationship between the first time domain resource and the second time domain resource is, when the first uplink transmission includes the preconfigured uplink channel or signal, the network device does not receive the first uplink transmission on the second time domain resource.

[0203] In some embodiments, the network device does not receive the first uplink transmission on the first time domain resources, wherein the second target time domain resources include the first time domain resources. In this case, the network device does not receive the first uplink transmission on the second time domain resources, including: the network device does not receive the first uplink transmission on the first time domain resources. In other words, as long as some of the first time domain resources fall within a cell DRX inactive period, the network device does not receive the first uplink transmission on the first time domain resources.

[0204] In some embodiments, the network device receives the first uplink transmission on time domain resources other than the second time domain resources in the first time domain resources, wherein the first target time domain resources include the time domain resources other than the second time domain resources in the first time domain resources. In other words, the network device does not receive the first uplink transmission on time domain resources in the first time domain resources that are within an inactive period of cell DRX, and receives the first uplink transmission on time domain resources in the first time domain resources that are not within an inactive period of cell DRX.

[0205] In some embodiments, the network device receives the first uplink transmission on a time domain resource that is located before the second time domain resource in the first time domain resources, and does not receive the first uplink transmission on a time domain resource that is located after the second time domain resource in the first time domain resources, wherein the first target time domain resource includes the time domain resource that is located before the second time domain resource in the first time domain resources, and the second target time domain resource includes the time domain resource that is located after the second time domain resource in the first time domain resources. For example, in case 1, the network device receives the first uplink transmission on a time domain resource that is within the activation period of the cell DRX in the first time domain resources (i.e., the time domain resource from t1 to t2). In case 2, the network device receives the first uplink transmission on a time domain resource that is within the activation period of the previous cell DRX in the first time domain resources (i.e., the time domain resource from t1 to t2), and does not receive the first uplink transmission on a time domain resource that is within the activation period of the next cell DRX in the first time domain resources (i.e., the time domain resource from t7 to t8). In case 4, the network device does not receive the first uplink transmission on the time domain resources within the active period of the cell DRX in the first time domain resources (i.e., the time domain resources from time t7 to time t9). That is, if the time domain resources within the inactive period of the cell DRX in the first time domain resources are located at the beginning of the first time domain resources, the network device receives the first uplink transmission; if the time domain resources within the inactive period of the cell DRX in the first time domain resources are located at the end of the first time domain resources, the network device does not receive the first uplink transmission.

[0206] In some embodiments, the network device does not receive the first uplink transmission on a time domain resource in the first time domain resources that is located before the second time domain resource, and receives the first uplink transmission on a time domain resource in the first time domain resources that is located after the second time domain resource, wherein the first target time domain resource includes the time domain resource in the first time domain resources that is located after the second time domain resource, and the second target time domain resource includes the time domain resource in the first time domain resources that is located before the second time domain resource. For example, in case 1, the network device does not receive the first uplink transmission on a time domain resource in the first time domain resources that is within the activation period of the cell DRX (i.e., the time domain resource from t1 to t2). In case 2, the network device does not receive the first uplink transmission on a time domain resource in the first time domain resources that is within the activation period of the previous cell DRX (i.e., the time domain resource from t1 to t2), and receives the first uplink transmission on a time domain resource in the first time domain resources that is within the activation period of the next cell DRX (i.e., the time domain resource from t7 to t8). In scenario 4, the network device receives the first uplink transmission on a time domain resource within the active period of the cell DRX in the first time domain resources (i.e., the time domain resource from time t7 to time t9). That is, if the time domain resource within the inactive period of the cell DRX in the first time domain resources is located at the beginning of the first time domain resources, the network device does not receive the first uplink transmission; if the time domain resource within the inactive period of the cell DRX in the first time domain resources is located at the end of the first time domain resources, the network device receives the first uplink transmission.

[0207] In some embodiments, when the first uplink transmission includes a preconfigured uplink channel or signal, the network device receiving the first uplink transmission on a first target time domain resource includes: in the absence of a second time domain resource, the network device receiving the first uplink transmission on the first time domain resource, wherein the first target time domain resource includes the first time domain resource. In other words, the network device receives the first uplink transmission on the first time domain resource as long as the first time domain resource does not belong to a cell DRX inactive period.

[0208] In some embodiments, the terminal device does not send the first uplink transmission, including at least one of the following situations: the terminal device cancels sending the first uplink transmission, and the terminal device does not prepare the first uplink transmission.

[0209] (2) The first uplink transmission includes a dynamically scheduled uplink channel or signal.

[0210] When the first uplink transmission includes a dynamically scheduled uplink channel or signal, the network device receives the first uplink transmission on the first target time domain resource, including: the network device receives the first uplink transmission on the first time domain resource; wherein the first target time domain resource includes the first time domain resource. In other words, regardless of which of the above situations 1 to 4 the positional relationship between the first time domain resource and the second time domain resource is, when the first uplink transmission includes the dynamically scheduled uplink channel or signal, the network device receives the first uplink transmission.

[0211] For a case where the first uplink transmission includes a preconfigured uplink channel or signal (e.g., CG-PUSCH or PUSCH carrying SP-CSI) and a PUCCH carrying HARQ-ACK information that overlap in the time domain, the network device receives the first uplink transmission on the first target time domain resource, including one of the following cases:

[0212] Receive PUCCH carrying HARQ-ACK information;

[0213] A pre-configured PUSCH is received, where the pre-configured PUSCH carries HARQ-ACK information.

[0214] In some embodiments, when the first uplink transmission includes a preconfigured PUSCH and a PUCCH carrying HARQ-ACK information that overlap in the time domain, the terminal device transmits the PUCCH carrying the HARQ-ACK information; accordingly, the network device receives the PUCCH carrying the HARQ-ACK information.

[0215] In some embodiments, when the first uplink transmission includes a preconfigured PUSCH and a PUCCH carrying HARQ-ACK information that overlap in the time domain, the terminal device transmits the preconfigured PUSCH, which carries the HARQ-ACK information; accordingly, the network device receives the preconfigured PUSCH, which carries the HARQ-ACK information.

[0216] In some embodiments, when it is determined according to the first configuration information that HARQ-ACK information and pre-configured PUSCH are not multiplexed, the PUCCH carrying the HARQ-ACK information is transmitted; accordingly, the network device receives the PUCCH carrying the HARQ-ACK information.

[0217] In some embodiments, when HARQ-ACK information and pre-configured PUSCH multiplexing are determined based on the first configuration information, the pre-configured PUSCH is transmitted, and the pre-configured PUSCH carries HARQ-ACK information; accordingly, the network device receives the pre-configured PUSCH, and the pre-configured PUSCH carries HARQ-ACK information.

[0218] In some embodiments, when the inactive period of cell DRX is determined by the DCI format, or when the cell DRX is activated or deactivated using the DCI format according to the second configuration information, the PUCCH carrying HARQ-ACK information is transmitted; accordingly, the network device receives the PUCCH carrying the HARQ-ACK information.

[0219] In some embodiments, when the inactive period of cell DRX is determined by the DCI format, or when the cell DRX is activated or deactivated using the DCI format according to the second configuration information, a pre-configured PUSCH is transmitted, and the pre-configured PUSCH carries the HARQ-ACK information; accordingly, the network device receives the pre-configured PUSCH, and the pre-configured PUSCH carries the HARQ-ACK information.

[0220] In some embodiments, when the inactive period of cell DRX is determined by RRC signaling, or when cell DRX is configured using RRC signaling according to third configuration information, a PUCCH carrying HARQ-ACK information is transmitted; accordingly, the network device receives the PUCCH carrying HARQ-ACK information.

[0221] In some embodiments, when the inactive period of cell DRX is determined by RRC signaling, or when it is determined based on third configuration information that RRC signaling is used to configure cell DRX, a pre-configured PUSCH is transmitted, and the pre-configured PUSCH carries HARQ-ACK information; accordingly, the network device receives the pre-configured PUSCH, and the pre-configured PUSCH carries HARQ-ACK information.

[0222] In some embodiments, the network device receives a PUCCH carrying HARQ-ACK information, including: if the pre-configured PUSCH and the PUCCH carrying HARQ-ACK information overlap on a third time domain resource, when the third time domain resource and the second time domain resource partially overlap or completely overlap, the network device receives the PUCCH carrying HARQ-ACK information on the third time domain resource. Alternatively, if the pre-configured PUSCH and the PUCCH carrying HARQ-ACK information overlap on the third time domain resource, when the third time domain resource and the second time domain resource do not overlap at all, the network device receives the PUCCH carrying HARQ-ACK information on the third time domain resource. Wherein, the first target time domain resource includes the third time domain resource.

[0223] In some embodiments, when the first uplink transmission includes a pre-configured PUSCH and a PUCCH carrying HARQ-ACK information, the network device receives the PUCCH carrying the HARQ-ACK information and does not receive the pre-configured PUSCH.

[0224] In some embodiments, when the first uplink transmission includes a preconfigured PUSCH and a PUCCH carrying HARQ-ACK information, if the preconfigured PUSCH and the PUCCH carrying HARQ-ACK information overlap on a third time domain resource, when the third time domain resource partially or completely overlaps with the second time domain resource, the network device receives the PUCCH carrying HARQ-ACK information on the third time domain resource, and / or the network device does not receive the preconfigured PUSCH. The network device not receiving the preconfigured PUSCH may mean that the network device does not receive the preconfigured PUSCH on the third time domain resource, or does not receive the preconfigured PUSCH on the second time domain resource, or does not receive the preconfigured PUSCH on the first time domain resource.

[0225] In some embodiments, when the first uplink transmission includes a pre-configured PUSCH and a PUCCH carrying HARQ-ACK information, if the pre-configured PUSCH and the PUCCH carrying HARQ-ACK information overlap on a third time domain resource, when the third time domain resource and the second time domain resource do not overlap at all, the network device receives the PUCCH carrying HARQ-ACK information on the third time domain resource, and / or the network device does not receive the pre-configured PUSCH. That is, in this case, as long as the PUCCH carrying HARQ-ACK information and the pre-configured PUSCH overlap in the time domain, the network device does not receive the pre-configured PUSCH. The network device does not receive the pre-configured PUSCH, which may be that the network device does not receive the pre-configured PUSCH on the third time domain resource, or does not receive the pre-configured PUSCH on the second time domain resource, or does not receive the pre-configured PUSCH on the first time domain resource.

[0226] In some embodiments, when the first uplink transmission includes a pre-configured PUSCH and a PUCCH carrying HARQ-ACK information, if the pre-configured PUSCH and the PUCCH carrying HARQ-ACK information overlap on a third time domain resource, when the third time domain resource and the second time domain resource do not overlap at all, the network device receives the pre-configured PUSCH carrying HARQ-ACK information on the third time domain resource, and / or the network device does not receive the pre-configured PUSCH on the second time domain resource. That is, in this case, if the pre-configured PUSCH and the PUCCH carrying HARQ-ACK information do not overlap on the time domain resources of the inactive period of the cell DRX, the terminal device still multiplexes the HARQ-ACK information onto the pre-configured PUSCH for transmission, and accordingly, the network device receives the pre-configured PUSCH carrying HARQ-ACK information.

[0227] In some embodiments, a network device receives a preconfigured PUSCH that carries HARQ-ACK information, including: if the preconfigured PUSCH and the PUCCH carrying the HARQ-ACK information overlap on a third time domain resource, when the third time domain resource and the second time domain resource partially overlap or completely overlap, the network device receives the preconfigured PUSCH carrying the HARQ-ACK information on the third time domain resource. Alternatively, if the preconfigured PUSCH and the PUCCH carrying the HARQ-ACK information overlap on the third time domain resource, when the third time domain resource and the second time domain resource do not overlap at all, the network device receives the preconfigured PUSCH carrying the HARQ-ACK information on the third time domain resource. Wherein, the first target time domain resource includes the third time domain resource.

[0228] In some embodiments, when the first uplink transmission includes a pre-configured PUSCH and a PUCCH carrying HARQ-ACK information, the network device receives the pre-configured PUSCH, where the pre-configured PUSCH carries the HARQ-ACK information.

[0229] In some embodiments, when the first uplink transmission includes a preconfigured PUSCH and a PUCCH carrying HARQ-ACK information, if the preconfigured PUSCH and the PUCCH carrying HARQ-ACK information overlap on a third time domain resource, when the third time domain resource and the second time domain resource partially overlap or fully overlap, the network device receives the preconfigured PUSCH carrying HARQ-ACK information on the third time domain resource, and / or the network device does not receive the preconfigured PUSCH on time domain resources in the second time domain resource other than the third time domain resource.

[0230] In some embodiments, when the first uplink transmission includes a preconfigured PUSCH and a PUCCH carrying HARQ-ACK information, if the preconfigured PUSCH and the PUCCH carrying HARQ-ACK information overlap on a third time domain resource, when the third time domain resource and the second time domain resource do not overlap at all, the network device receives the preconfigured PUSCH carrying HARQ-ACK information on the third time domain resource, and / or the network device does not receive the preconfigured PUSCH on the second time domain resource.

[0231] In some embodiments, when the first uplink transmission includes a pre-configured PUSCH and a PUCCH carrying HARQ-ACK information, the behavior of the terminal device is determined according to the first configuration information sent by the network device. In some embodiments, the first configuration information is used to configure whether the HARQ-ACK information and the pre-configured PUSCH are multiplexed during the non-activation period of the cell DRX. In some embodiments, when it is determined according to the first configuration information that the HARQ-ACK information and the pre-configured PUSCH are not multiplexed, the terminal device transmits the PUCCH carrying the HARQ-ACK information and does not transmit the pre-configured PUSCH; accordingly, the network device receives the PUCCH carrying the HARQ-ACK information and does not receive the pre-configured PUSCH. In some embodiments, when it is determined according to the first configuration information that the HARQ-ACK information and the pre-configured PUSCH are multiplexed, the terminal device transmits the pre-configured PUSCH, which carries the HARQ-ACK information; accordingly, the network device receives the pre-configured PUSCH, which carries the HARQ-ACK information.
