[0018] Traditional communication systems typically support a limited number of connections and are easy to implement. However, with the development of communication technology, mobile communication systems will not only support traditional communication but also, 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. The embodiments of this application can also be applied to these communication systems.

[0019] The communication system in this application embodiment can be applied to carrier aggregation (CA) scenarios, dual connectivity (DC) scenarios, and standalone (SA) network deployment scenarios.

[0020] The communication system in this application embodiment can be applied to unlicensed spectrum, wherein unlicensed spectrum can also be considered as shared spectrum; or, the communication system in this application embodiment can also be applied to licensed spectrum, wherein licensed spectrum can also be considered as non-shared spectrum.

[0021] The embodiments of this application can be applied to both non-terrestrial network (NTN) systems and terrestrial network (TN) systems. NTN systems generally provide communication services to terrestrial users via satellite communication. Currently, NTN systems include NR-NTN and IoT-NTN systems, and other NTN systems may be included in the future.

[0022] For example, Figure 1 This is a schematic diagram of the architecture of a communication system provided in an embodiment of this application. Figure 1 As shown, the communication system 100 may include a network device 110, which may be a device that communicates with a terminal device 120. The network device 110 may provide communication coverage for a specific geographical area and may communicate with terminal devices located within that coverage area.

[0023] Figure 1 An exemplary diagram shows a network device 110 and two terminal devices 120. In some embodiments of this application, the communication system 100 may include multiple network devices and each network device may include other numbers of terminal devices within its coverage area. This application does not limit the scope of the embodiments.

[0024] For example, Figure 2 This is a schematic diagram of the architecture of another communication system provided in an embodiment of this application. Please refer to... Figure 2 The communication system may include terminal device 201 and satellite 202, and wireless communication is possible between terminal device 201 and satellite 202. The network formed between terminal device 201 and satellite 202 may also be called an NTN. Figure 2In the architecture of the communication system shown, satellite 202 can function as a base station, and terminal device 201 and satellite 202 can communicate directly. In this system architecture, satellite 202 can be referred to as a network device.

Figure 3 The communication system includes terminal device 301, satellite 302, and base station 303. Terminal device 301 and satellite 302 can communicate wirelessly, and satellite 302 can communicate with base station 303. The network formed by terminal device 301, satellite 302, and base station 303 can also be called an NTN. Figure 3 In the architecture of the communication system shown, satellite 302 may not function as a base station, and communication between terminal device 301 and base station 303 requires relay through satellite 302. In this system architecture, base station 303 can be referred to as a network device. In some embodiments of this application, the communication system may include multiple base stations 303, each base station 303 can communicate with one or more satellites 302, and the coverage area of ​​each satellite 302 may include other numbers of terminal devices; however, this application does not limit this aspect.

[0026] In future communication systems such as B5G (Beyound 5G) or 6G, there may also be distributed multiple-input multiple-output (MIMO, also known as distributed antenna system) scenarios and / or massive multiple-input multiple-output (MIMO, also known as massive antenna matrix system) scenarios. In some cases, distributed MIMO and / or massive MIMO can also support cell-free or UE-centric network deployment scenarios. It should be understood that the above scenarios also apply to TN and / or NTN.

Optionally, the terminal device 10 may also be a cellular phone, cordless phone, SIP (Session Initiation Protocol) phone, WLL (Wireless Local Loop) station, PDA (Personal Digital Assistant), handheld device with wireless communication function, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, terminal device in 5GS (5th Generation System), or terminal device in the future evolved PLMN (Public Land Mobile Network), etc., and the embodiments of this application are not limited thereto. For ease of description, the devices mentioned above are collectively referred to as terminal devices. In the embodiments of this application, "terminal device" and "UE" are usually used interchangeably, but those skilled in the art will understand that they can express the same meaning.

[0028] The network devices mentioned in this application embodiment can be access network devices, 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 can include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different wireless access technologies, the names of devices with access network device functions may differ; for example, in a 5G NR system, they are called gNodeB or gNB. As communication technologies evolve, the name "access network device" may change. For ease of description, in this application embodiment, the aforementioned devices providing wireless communication functions for terminal devices are collectively referred to as access network devices. Optionally, a communication relationship can be established between the terminal device and the core network device through the access network device.

[0029] The "5G NR system" in this application embodiment can 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 this application embodiment can be applied to LTE systems, 5G NR systems, and subsequent evolution systems of 5G NR systems (such as B5G systems, 6G systems), and can also be applied to other communication systems such as NB-IoT (Narrow Band Internet of Things) systems. This application does not limit these applications.

[0030] In this embodiment, the network device can provide services to a cell. The terminal device communicates with the network device through the transmission resources (e.g., frequency domain resources, or spectrum resources) on the carrier used by the cell. The cell can be the cell corresponding to the network device (e.g., a base station). The cell can belong to a macro base station or to a base station corresponding to a small cell. The small cell can include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-speed data transmission services.

[0031] Before introducing the technical solution of this application, the relevant technologies involved in this application will be described first. The following relevant technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0032] 1. Network energy saving Network energy saving is crucial for environmental sustainability, reducing environmental impact (such as greenhouse gas emissions), and saving operating costs. As 5G becomes more widespread across industries and geographic regions, the need to support very high data transmission rates to handle more advanced services and applications (such as extended reality (XR)) necessitates denser network deployments, utilizing more antennas, greater bandwidth, and more frequency bands. Given the environmental impact of 5G, there is a need to develop controlled, new solutions to enhance network energy efficiency.

[0033] Energy consumption has become a critical component of operators' operational expenditure (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 energy consumption originates from the radio access network, more specifically from the active antenna unit (AAU), with data centers and fiber optic transmission accounting for a smaller share. The power consumption of a single radio access session can be divided into two parts: the dynamic part includes only the power consumption when data is being transmitted or received; the static part includes the power consumption necessary for the necessary operation of the radio access equipment at all times, including when no data is being transmitted or received.

[0034] 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 identify and study network energy-saving technologies in target deployment scenarios. The already defined power consumption models on the terminal device side can serve as a reference. This research should focus on how to achieve more efficient dynamic and / or semi-static operation, and consider one or more network energy-saving technologies applied to the time, frequency, spatial, and power domains, combined with potential terminal device feedback support, potential terminal device auxiliary information, and information exchange or coordination technologies between network interfaces, to achieve more granular adaptive data transmission and / or reception.

[0035] It is worth noting that this study not only assesses potential network energy-saving gains, but also needs to evaluate and balance the impact on network and user performance by observing KPIs such as spectral efficiency, capacity, user-perceived throughput (UPT), latency, UE power consumption, complexity, handover performance, call drop rate, initial access performance, and security-related KPIs of service level agreements (SLAs). This study should avoid having a significant impact on the aforementioned KPIs.

[0036] 2. Cell DTX and / or Cell DRX Configuration in the NR System In NR systems, to achieve network energy savings, network devices can configure cell DTX and / or cell DRX for terminal devices. During the inactive period of the configured cell DTX on the terminal device, the network device may not transmit specific downlink channels or signals, and / or, the terminal device may not receive specific downlink channels or signals. During the inactive period of the configured cell DRX on the terminal device, the terminal device may not transmit specific downlink channels or signals, and / or, the network device may not receive specific uplink channels or signals. This method achieves energy savings for network devices.

[0037] Currently, network devices can be configured with cell DTX and cell DRX independently, or simultaneously. Cell DTX and / or cell DRX configurations can be activated via RRC (Radio Resource Control) signaling, or activated / deactivated via DCI (Downlink Control Information) signaling.

[0038] When the configuration of cell DTX and / or cell DRX is activated or deactivated via DCI signaling, if the terminal device receives a DCI format 2_9 indicating a change in the activation or deactivation status of cell DTX and / or cell DRX of the second cell on time slot m of the downlink active BWP (Bandwidth Part) of the first cell, then the terminal device activates or deactivates cell DTX and / or cell DRX on the downlink active BWP and / or uplink active BWP of the second cell starting from the first time slot according to the indication information (i.e., the DCI format 2_9). The first time slot is not earlier than the starting position of time slot m+d on the downlink active BWP of the first cell, where d is the number of time slots determined according to the subcarrier spacing of the downlink active BWP of the first cell, and the values ​​are shown in Table 1 below.

[0039]

[0040] As an example, the second cell of the terminal device is configured with cell DRX and the cell DRX is inactive. When the terminal device receives a first DCI of format 2_9 in 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 on the uplink activation BWP of the second cell starting from the first time slot according to the indication information (i.e., the first DCI), wherein the first time slot is not 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 of format 2_9 in 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 on the uplink activation BWP of the second cell starting from the second time slot according to the indication information (i.e., the second DCI), wherein the second time slot is not earlier than the starting position of time slot m2+d on the downlink activation BWP of the first cell. Figure 4 A schematic diagram illustrating the activation or deactivation of the second cell's DRX via DCI signaling is provided. Figure 4In this example, we assume that the SCS (Subcarrier Spacing) of the downlink active BWP in the first cell is 30 kHz, i.e., d is 6; and the SCS of the uplink active BWP in the second cell is 15 kHz. It should be noted that the first and second cells can be the same cell or different cells.

[0041] Please refer to Figure 5 This document illustrates a flowchart of a wireless communication method provided in an embodiment of this application. The method can be executed by a terminal device. The method may include the following steps: Step 510: The first uplink transmission of the terminal device occupies the first time domain resource. The second time domain resource is the part of the first time domain resource that overlaps with the time domain resource of the cell DRX inactive period. 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.

[0042] In some embodiments, the first uplink transmission includes a pre-configured uplink channel or signal. In some embodiments, the pre-configured uplink channel or signal includes one or more of the following: CG-PUSCH (Configured Grant Physical Uplink Shared Channel), SRS (Sounding Reference Signal) configured by RRC, SRS activated by MAC CE (Media Access Control Control Element), 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).

[0043] In some embodiments, the first uplink transmission includes one or more pre-configured uplink channels or signals.

[0044] In some embodiments, when the first uplink transmission includes a plurality of pre-configured uplink channels or signals, the plurality of pre-configured uplink channels or signals are transmitted repeatedly, or the plurality of pre-configured uplink channels or signals are not transmitted repeatedly.

[0045] For example, when the pre-configured uplink channel or signal includes a 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.

[0046] For example, when the pre-configured uplink channel or signal includes SRS, the first uplink transmission includes one or more SRS.

[0047] For example, when the pre-configured uplink channel or signal includes a PUCCH, the first uplink transmission includes one PUCCH; or, the first uplink transmission includes multiple PUCCHs that are transmitted repeatedly.

[0048] In some embodiments, the first uplink transmission includes dynamically scheduled uplink channels or signals. In some embodiments, the dynamically scheduled uplink channels or signals include one or more of the following: a DCI-scheduled PUSCH, a DCI-triggered SRS, and a PUCCH carrying HARQ-ACK information.

[0049] In some embodiments, when the first uplink transmission includes a plurality of dynamically scheduled uplink channels or signals, the plurality of dynamically scheduled uplink channels or signals are transmitted repeatedly, or the plurality of dynamically scheduled uplink channels or signals are not transmitted repeatedly.

[0050] In some embodiments, the active and inactive periods of a cell DRX are arranged alternately. During the inactive 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.

[0051] Normally, during the inactive period of a cell's DRX (Digital Route Registry), terminal devices do not transmit pre-configured uplink channels or signals, and network devices do not receive pre-configured uplink channels or signals. Since dynamically scheduled uplink channels or signals are dynamically determined by the network device based on service transmission requirements, if the network device does not expect the terminal device to transmit during the inactive period of the cell's DRX, it can skip scheduling. Therefore, if the network device dynamically schedules the terminal device to transmit uplink channels or signals during the inactive period of the cell's DRX, the terminal device needs to transmit the dynamically scheduled uplink channels or signals, and correspondingly, the network device can receive the dynamically scheduled uplink channels or signals. Additionally, during the inactive period of the cell's DRX, if the terminal device needs to provide HARQ-ACK information feedback for the received downlink channels or signals, the terminal device needs to transmit this HARQ-ACK information.

[0052] In this embodiment, the first uplink transmission of the terminal device occupies a first time-domain resource, and the second time-domain resource in the first time-domain resource is the portion of the first time-domain resource that overlaps with the time-domain resource of the inactive 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 with part or all of the time-domain resource of the inactive 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 inactive period of the cell DRX.

[0053] The positional relationship between the first time-domain resource and the second time-domain resource includes one of the following cases.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] like Figure 6 As shown, it illustrates the positional relationship between the first time-domain resource and the second time-domain resource.

[0059] For scenario 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's DRX, and the ending position of the first time-domain resource is the same as the ending position of the second time-domain resource.

[0060] For scenario 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's DRX, and the ending position of the first time domain resource is within another activation period of the cell's DRX.

[0061] 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.

[0062] For scenario 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's DRX.

[0063] The behavior of the terminal device will be explained below 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.

[0064] (1) The first uplink transmission includes a pre-configured uplink channel or signal.

[0065] When the first uplink transmission includes a pre-configured uplink channel or signal, the terminal device does not transmit the first uplink transmission on the second target time domain resource. This includes: the terminal device does not transmit 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 the positional relationship between the first and second time domain resources (as described in cases 1 to 4 above), when the first uplink transmission includes a pre-configured uplink channel or signal, the terminal device does not transmit the first uplink transmission on the second time domain resource.

[0066] In some embodiments, the terminal device does not transmit the first uplink transmission on the first time domain resource, wherein the second target time domain resource includes the first time domain resource. In this case, the terminal device not transmitting the first uplink transmission on the second time domain resource includes: the terminal device not transmitting the first uplink transmission on the first time domain resource. That is, as long as a portion of the resources in the first time domain resource belongs to the inactive period of the cell's DRX, the terminal device does not transmit the first uplink transmission on the first time domain resource.

[0067] In some embodiments, the terminal device transmits a 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 time domain resources other than the second time domain resources in the first time domain resources. That is, the terminal device does not transmit the first uplink transmission on time domain resources in the first time domain resources that belong to the inactive period of the cell DRX, and transmits the first uplink transmission on time domain resources in the first time domain resources that do not belong to the inactive period of the cell DRX.

[0068] In some embodiments, the terminal device transmits a first uplink transmission on time domain resources that precede the second time domain resource in the first time domain resource, and does not transmit a first uplink transmission on time domain resources that follow the second time domain resource in the first time domain resource. The first target time domain resource includes time domain resources that precede the second time domain resource in the first time domain resource, and the second target time domain resource includes time domain resources that follow the second time domain resource in the first time domain resource. For example, in case 1, the terminal device transmits a first uplink transmission on time domain resources within the activation period of the cell DRX in the first time domain resource (i.e., time domain resources from t1 to t2). In case 2, the terminal device transmits a first uplink transmission on time domain resources within the activation period of the preceding cell DRX in the first time domain resource (i.e., time domain resources from t1 to t2), and does not transmit a first uplink transmission on time domain resources within the activation period of the following cell DRX in the first time domain resource (i.e., time domain resources from t7 to t8). In scenario 4, the terminal device does not send the first uplink transmission on the time domain resources within the active period of the cell DRX (i.e., time domain resources from t7 to t9) in the first time domain resources. That is, if the time domain resources 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 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.

[0069] In some embodiments, the terminal device does not transmit the first uplink transmission on time domain resources that are located before the second time domain resources in the first time domain resources, but transmits the first uplink transmission on time domain resources that are located after the second time domain resources in the first time domain resources. The first target time domain resources include time domain resources located after the second time domain resources in the first time domain resources, and the second target time domain resources include time domain resources located before the second time domain resources in the first time domain resources. For example, in case 1, the terminal device does not transmit the first uplink transmission on time domain resources within the activation period of the cell DRX in the first time domain resources (i.e., time domain resources from t1 to t2). In case 2, the terminal device does not transmit the first uplink transmission on time domain resources within the activation period of the preceding cell DRX in the first time domain resources (i.e., time domain resources from t1 to t2), but transmits the first uplink transmission on time domain resources within the activation period of the following cell DRX in the first time domain resources (i.e., time domain resources from t7 to t8). In scenario 4, the terminal device transmits the first uplink transmission on the time domain resources within the active period of the cell DRX (i.e., time domain resources from t7 to t9) in the first time domain resources. That is, if the time domain resources within the inactive period of the cell DRX are located at the beginning of the first time domain resources, the terminal device does not transmit the first uplink transmission; if the time domain resources within the inactive period of the cell DRX are located at the end of the first time domain resources, the terminal device transmits the first uplink transmission.

[0070] In some embodiments, when the first uplink transmission includes a pre-configured uplink channel or signal, the terminal device transmits the first uplink transmission on the first target time domain resource, including: in the absence of a second time domain resource, the terminal device transmits 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, as long as the first time domain resource does not belong to the inactive period of the cell DRX, the terminal device must transmit the first uplink transmission on the first time domain resource.

[0071] In some embodiments, time-domain resources that do not belong to the inactive period of cell DRX include at least one of the following: time-domain resources that belong to the active period of cell DRX, and time-domain resources when there is no cell DRX (e.g., time-domain resources after cell DRX is deactivated).

[0072] In some embodiments, the terminal device does not send the first uplink transmission, including at least one of the following: the terminal device cancels sending the first uplink transmission, or the terminal device is not prepared to send the first uplink transmission.

[0073] (2) The first uplink transmission includes dynamically scheduled uplink channels or signals.

[0074] When the first uplink transmission includes a dynamically scheduled uplink channel or signal, the terminal device transmits the first uplink transmission on the first target time domain resource, including: the terminal device transmitting 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 the positional relationship between the first time domain resource and the second time domain resource in any of the above situations 1 to 4, the terminal device transmits the first uplink transmission when the first uplink transmission includes a dynamically scheduled uplink channel or signal.

[0075] It should be understood that in related technologies, if a PUCCH carrying HARQ-ACK information collides with a pre-configured uplink channel or signal (e.g., CG-PUSCH or PUSCH carrying SP-CSI) to be transmitted by the terminal device in the time domain, the terminal device can multiplex the HARQ-ACK information onto the CG-PUSCH or the PUSCH carrying SP-CSI for transmission. That is, the terminal device only transmits the PUSCH, which carries the HARQ-ACK information. Since the terminal device needs to send a PUCCH carrying HARQ-ACK information during the inactive period of the cell DRX but is not expected to send a pre-configured uplink channel or signal (e.g., CG-PUSCH or PUSCH carrying SP-CSI), the behavior of the terminal device needs to be defined when the PUCCH carrying HARQ-ACK information collides with the CG-PUSCH or the PUSCH carrying SP-CSI to be transmitted by the terminal device in the time domain during the inactive period of the cell DRX.

[0076] In the case where the first uplink transmission includes a pre-configured PUSCH (e.g., CG-PUSCH or PUSCH carrying SP-CSI) and a PUCCH carrying HARQ-ACK information that overlap in the time domain, the terminal device transmits the first uplink transmission on the first target time domain resource, including one of the following cases a to h.

[0077] Case a: The terminal device transmits a PUCCH carrying HARQ-ACK information.

[0078] Case b: The terminal device transmits a pre-configured PUSCH, which carries HARQ-ACK information.

[0079] Case c: When it is determined from the first configuration information that HARQ-ACK information and pre-configured PUSCH are not reused, the terminal device transmits PUCCH carrying HARQ-ACK information.

[0080] Case d: When HARQ-ACK information and pre-configured PUSCH are multiplexed based on the first configuration information, the terminal device transmits the pre-configured PUSCH, which carries HARQ-ACK information.

[0081] Case e: When the inactive period of cell DRX is determined by DCI format, or when the activation or deactivation of cell DRX is determined by using DCI format according to the second configuration information, the terminal device transmits PUCCH carrying HARQ-ACK information.

[0082] Case f: When the inactive period of cell DRX is determined by DCI format, or when the activation or deactivation of cell DRX is determined by DCI format according to the second configuration information, the terminal device transmits a pre-configured PUSCH, which carries HARQ-ACK information.

[0083] Case g: When the inactive period of cell DRX is determined by RRC signaling, or when it is determined by third configuration information to use RRC signaling to configure cell DRX, the terminal device transmits PUCCH carrying HARQ-ACK information.

[0084] Case h: When the inactive period of cell DRX is determined by RRC signaling, or when it is determined by third configuration information to use RRC signaling to configure cell DRX, the terminal device transmits a pre-configured PUSCH, which carries HARQ-ACK information.

[0085] In some embodiments, the pre-configured PUSCH includes a CG-PUSCH or a PUSCH carrying an SP-CSI.

[0086] In some embodiments, the terminal device transmits a PUCCH carrying HARQ-ACK information, including: if a pre-configured PUSCH and a PUCCH carrying HARQ-ACK information overlap on a third time-domain resource, and when the third time-domain resource partially or completely overlaps with the second time-domain resource, the terminal device transmits the PUCCH carrying HARQ-ACK information on the third time-domain resource. Alternatively, if a pre-configured PUSCH and a PUCCH carrying HARQ-ACK information overlap on a third time-domain resource, and 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. The first target time-domain resource includes the third time-domain resource.

[0087] 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 HARQ-ACK information but does not transmit the pre-configured PUSCH.

[0088] 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, and if the third time-domain resource partially or completely overlaps with the second time-domain resource, 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 terminal device not transmitting the pre-configured PUSCH can 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.

[0089] 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, and if 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. The terminal device not transmitting the pre-configured PUSCH can mean that the terminal device does not transmit the pre-configured PUSCH on the third time-domain resource, or on the second time-domain resource, or on the first time-domain resource.

[0090] 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, and if 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 cell DRX's inactive period, then the terminal device still multiplexes the HARQ-ACK information onto the pre-configured PUSCH for transmission.

[0091] In some embodiments, the terminal device transmits a pre-configured PUSCH carrying HARQ-ACK information, including: if the pre-configured PUSCH and the PUSCH carrying HARQ-ACK information overlap on a third time-domain resource, and when the third time-domain resource partially or completely overlaps with the second time-domain resource, the terminal device transmits the pre-configured PUSCH carrying HARQ-ACK information on the third time-domain resource. Alternatively, if the pre-configured PUSCH and the PUSCH carrying HARQ-ACK information overlap on a third time-domain resource, and 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. The first target time-domain resource includes the third time-domain resource.

[0092] 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 HARQ-ACK information.

[0093] 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, and if the third time domain resource partially or completely overlaps with the second time domain resource, 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 other than the third time domain resource in the second time domain resource.

[0094] 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, and if 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.

[0095] 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 based on first configuration information. In some embodiments, the first configuration information is used to configure whether HARQ-ACK information and the pre-configured PUSCH are reused during the inactive period of the cell DRX. In some embodiments, when it is determined according to the first configuration information that HARQ-ACK information and the pre-configured PUSCH are not reused, the terminal device transmits the PUCCH carrying 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 HARQ-ACK information and the pre-configured PUSCH are reused, the terminal device transmits the pre-configured PUSCH, which carries HARQ-ACK information.

[0096] 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 during 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 PUCCH carrying HARQ-ACK information and does not transmit the pre-configured PUSCH; 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 pre-configured PUSCH, which carries HARQ-ACK information.

[0097] In some embodiments, the first DCI format is DCI format 2_9.

[0098] In other words, when the inactive period of a cell's DRX is determined via RRC signaling, if a PUCCH carrying HARQ-ACK information and a pre-configured PUSCH to be transmitted by the terminal device collide on time-domain resources within the inactive period of the cell's DRX, the terminal device will transmit the PUCCH carrying HARQ-ACK information and will not transmit the pre-configured PUSCH. When the inactive period of a cell's DRX is determined via DCI signaling, if a PUCCH carrying HARQ-ACK information and a pre-configured PUSCH to be transmitted by the terminal device collide on time-domain resources within the inactive period of the cell's DRX, the terminal device will transmit the pre-configured PUSCH carrying HARQ-ACK information. This is mainly because the terminal device has a certain bit error rate when listening to the DCI format. That is, there may be situations where the terminal device does not receive the DCI format of the activated or deactivated cell DRX. Therefore, it may misunderstand the cell's inactive period. In order to avoid the transmission of HARQ-ACK information and pre-configured PUSCH due to the misunderstanding of the cell's inactive period, the behavior of the terminal device can be specified, such as always transmitting the pre-configured PUSCH carrying HARQ-ACK information or always transmitting the PUCCH carrying HARQ-ACK information.

[0099] By using the above method, when the inactive period of the 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 equipment collide on the time domain resources during the inactive period of the cell DRX, it is stipulated that the HARQ-ACK information should always be multiplexed onto the pre-configured PUSCH for transmission or the PUCCH carrying HARQ-ACK information should always be transmitted. This can avoid inconsistencies in the understanding of the uplink channel or signal to be transmitted between the network equipment and the terminal equipment.

[0100] 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 during 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 carrying 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 HARQ-ACK information and does not transmit the pre-configured PUSCH.

[0101] In some embodiments, when the terminal device is configured to activate or deactivate a cell DRX in DCI format, if the first uplink transmission includes a pre-configured PUSCH and a PUCCH carrying HARQ-ACK information, the terminal device transmits the PUCCH carrying HARQ-ACK information and does not transmit the pre-configured PUSCH.

[0102] In some embodiments, if the terminal device is configured to activate or deactivate a cell DRX in DCI format, when the pre-configured PUSCH and the PUCCH carrying HARQ-ACK information overlap in the time domain, the terminal device always disregards 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 to activate or deactivate a cell DRX in DCI format, when the CG-PUSCH or the PUSCH carrying SP-CSI and the PUCCH carrying HARQ-ACK information overlap in the time domain resources during the inactive period of the 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 in the time domain resources during the active period of the cell DRX, the terminal device still transmits the PUCCH carrying HARQ-ACK information.

[0103] In some embodiments, if the cell DRX is configured using RRC signaling, when a pre-configured PUSCH and a PUCCH carrying HARQ-ACK information overlap in the time domain during the inactive period of the cell DRX, the terminal device does not consider the multiplexing of the pre-configured PUSCH and the PUCCH carrying HARQ-ACK information; that is, the terminal device transmits the PUCCH carrying HARQ-ACK information during the inactive period of the cell DRX. For example, if the cell DRX is configured using RRC signaling, when a CG-PUSCH or a PUSCH carrying SP-CSI and a PUCCH carrying HARQ-ACK information overlap in the time domain resources during the inactive period of the cell DRX, the terminal device transmits the PUCCH carrying HARQ-ACK information; or when a CG-PUSCH or a PUSCH carrying SP-CSI and a PUCCH carrying HARQ-ACK information overlap in the time domain resources during the active period of the cell DRX, the terminal device transmits the PUSCH carrying HARQ-ACK information.

[0104] It should be understood that a certain processing time is required for the terminal device to prepare to send or cancel the first uplink transmission. If the terminal device receives a signaling instruction to cancel the first uplink transmission after it has already begun preparing to send it, the terminal device will not be able to cancel the first uplink transmission. Alternatively, if the terminal device receives a signaling instruction to send the first uplink transmission, but the time between receiving the signaling instruction and the time of sending the first uplink transmission is less than the processing time, the terminal device will also be unable to send the first uplink transmission because it does not have enough time to prepare.

[0105] In some embodiments of this application, whether the terminal device sends a first uplink transmission needs to be determined based on the overlap between the first time-domain resources occupied by the first uplink transmission and the time-domain resources of the cell DRX inactive period. When the cell DRX inactive period is determined by the first DCI format, in addition to considering the impact of the cell DRX inactive period, the processing time for canceling the first uplink transmission and / or the processing time for preparing the first uplink transmission by the terminal device also need to be considered. That is to say, the aforementioned behavior of the terminal device in sending or not sending the first uplink transmission is also subject to the influence of the first condition and / or the second condition.

[0106] In some embodiments, the terminal device transmits a first uplink transmission on a first target time domain resource, including: if a first condition is met, the terminal device transmits a first uplink transmission on the first target time domain resource; and / or, if the first condition is not met, the terminal device does not transmit a first uplink transmission on the first target time domain resource.

[0107] In some embodiments, a portion of the time-domain resources in the first target time-domain resources do not belong to the inactive period of the cell DRX.

[0108] In some embodiments, all time-domain resources in the first target time-domain resources do not belong to the inactive period of the cell DRX.

[0109] In some embodiments, the first condition includes conditions related to a first processing time length. For example, the first processing time length refers to the processing time length during which the terminal device prepares for a first uplink transmission.

[0110] In some embodiments, the terminal device transmits a first uplink transmission on a first target time domain resource, including: the terminal device transmits at least a portion of the transmission in the first uplink transmission on the first target time domain resource.

[0111] In some embodiments, when the inactive period of a 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 a cell DRX.

[0112] In some embodiments, the first target time-domain resource includes the time-domain resource determined in the foregoing embodiments to be used for the first uplink transmission.

[0113] In some embodiments, the first target time-domain resource includes at least one of the following: First-time domain resources; Time-domain resources other than the second time-domain resources in the first time-domain resources; The time domain resource that precedes the second time domain resource in the first time domain resource; The time domain resource located after the second time domain resource in the first time domain resource.

[0114] For example, the first target time domain resource includes a first time domain resource, and the terminal device sends a first uplink transmission on the first time domain resource, including: when a first condition is met, the terminal device sends a first uplink transmission on the first time domain resource; and / or, when the first condition is not met, the terminal device does not send a first uplink transmission on the first time domain resource.

[0115] For example, the first target time domain resource includes time domain resources other than the second time domain resource in the first time domain resource. The terminal device sends a first uplink transmission on the time domain resources other than the second time domain resource in the first time domain resource, including: when a first condition is met, the terminal device sends a first uplink transmission on the time domain resources other than the second time domain resource in the first time domain resource; and / or, when the first condition is not met, the terminal device does not send a first uplink transmission on the time domain resources other than the second time domain resource in the first time domain resource.

[0116] For example, the first target time domain resource includes time domain resources located before the second time domain resource in the first time domain resource. The terminal device sends a first uplink transmission on the time domain resources located before the second time domain resource in the first time domain resource, including: when a first condition is met, the terminal device sends a first uplink transmission on the time domain resources located before the second time domain resource in the first time domain resource; and / or, when the first condition is not met, the terminal device does not send a first uplink transmission on the time domain resources located before the second time domain resource in the first time domain resource.

[0117] For example, the first target time domain resource includes time domain resources located after the second time domain resource in the first time domain resource. The terminal device sends a first uplink transmission on the time domain resources located after the second time domain resource in the first time domain resource, including: when a first condition is met, the terminal device sends a first uplink transmission on the time domain resources located after the second time domain resource in the first time domain resource; and / or, when the first condition is not met, the terminal device does not send a first uplink transmission on the time domain resources located after the second time domain resource in the first time domain resource.

[0118] In some embodiments, the first processing time length condition refers to a condition related to a 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 transmits a first uplink transmission on the first target time domain resource; and / or, when the first condition is not met, the terminal device does not transmit the first uplink transmission on the first target time domain resource. This can be replaced by: when the first processing time length condition is met, the terminal device transmits a 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 transmit the first uplink transmission on the first target time domain resource.

[0119] In some embodiments, the first condition (or the first processing time length condition) includes: the interval between the first time domain location 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 between the first time domain location 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 between the first time domain location and the starting position of the first target time domain resource is less than the first processing time length.

[0120] In some embodiments, the first condition (or the first processing time length condition) includes: the interval between the first time-domain location 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 between the first time-domain location 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 between the first time-domain location and the starting position of the first time-domain resource is less than the first processing time length.

[0121] In some embodiments, the first time-domain location includes one of the following: The terminal device receives the last symbol of the PDCCH (Physical Downlink Control Channel) carrying the first DCI format; The terminal device receives the end position of the time slot containing the last symbol of the PDCCH receiving the first DCI format; The terminal device is configured to receive the last symbol of the PDCCH received for transmitting a first DCI format; that is, the terminal device detects the last symbol of the CORESET (Control Resource Set) of the first DCI format. The terminal device is configured to receive the end position of the time slot containing the last symbol of the PDCCH received in the first DCI format; The effective time of the activated cell DRX is determined according to the first DCI format; for example... Figure 4 The start time of slot m1+6 for downlink activation BWP in the first cell; or Figure 4 The start time of the first time slot of the uplink activated BWP in the second cell; The effective time of deactivation cell DRX is determined based on the first DCI format; for example... Figure 4 The start time of slot m2+6 for downlink activation BWP in the first cell; or Figure 4 The start time of the second time slot of the uplink activation BWP in the second cell; The effective time of the first DCI format; for example, the starting position of slot m+d on the downlink active BWP of the first cell as determined according to Table 1; or the starting position of the first slot; The first DCI format is used to indicate whether to activate or deactivate the cell DRX, and / or the first DCI format is used to indicate whether the cell enters a network power-saving mode, for example, to indicate that the cell is turned off.

[0122] The following example illustrates this point, using the case where all time-domain resources in the first time-domain resource do not belong to the inactive period of the cell's DRX. For example... Figure 7As shown, the first time-domain resource is the time-domain resource pre-configured by the terminal device for uplink channels or signals. Originally, it belongs to the inactive period of the cell's DRX. However, based on the received first DCI format used to indicate deactivation of the cell's DRX, the terminal device determines that the first time-domain resource does not belong to the inactive period of the cell's 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 time interval between the first time-domain position and the start position of the first time-domain resource meets the first processing time length condition. Specifically, if 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.

[0123] In some embodiments, the terminal device does not send the first uplink transmission on the second target time domain resource, including: if a 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.

[0124] In some embodiments, a portion of the time-domain resources in the second target time-domain resources belong to the inactive period of the cell DRX.

[0125] In some embodiments, all time-domain resources in the second target time-domain resources belong to the inactive period of the cell DRX.

[0126] In some embodiments, the second condition includes a condition related to a second processing time length. For example, the second processing time length refers to the processing time length during which the terminal device cancels the first uplink transmission.

[0127] In some embodiments, the terminal device not transmitting the first uplink transmission on the second target time domain resource includes: the terminal device not transmitting at least a portion of the transmission in the first uplink transmission on the second target time domain resource.

[0128] In some embodiments, when the inactive period of cell DRX is determined by a first DCI format, if a second condition is met, the terminal device does not send a first uplink transmission on the second target time domain resource; and / or, if the second condition is not met, the terminal device sends a first uplink transmission on the second target time domain resource in the first time domain resource, wherein at least a portion of the time domain resources in the second target time domain resource belong to the inactive period of cell DRX.

[0129] In some embodiments, the second target time-domain resource includes the time-domain resource determined in the foregoing embodiments not to send the first uplink transmission.

[0130] In some embodiments, the second target time-domain resource includes at least one of the following: Second time-domain resources; First-time domain resources; The time domain resource that precedes the second time domain resource in the first time domain resource; The time domain resource located after the second time domain resource in the first time domain resource.

[0131] For example, the second target time domain resource includes a second time domain resource, and the terminal device does not send the first uplink transmission on the second time domain resource, including: when a 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.

[0132] For example, the second target time domain resource includes the first time domain resource. 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.

[0133] For example, the second target time domain resource includes the time domain resource in the first time domain resource that is located before the second time domain resource. 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 a 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.

[0134] For example, the second target time domain resource includes the time domain resource located after the second time domain resource in the first time domain resource. The terminal device does not send the first uplink transmission on the time domain resource located after the second time domain resource in the first time domain resource, including: when a second condition is met, the terminal device does not send the first uplink transmission on the time domain resource located after the second time domain resource in the first 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 located after the second time domain resource in the first time domain resource.

[0135] 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. This 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.

[0136] In some embodiments, the second condition (or second processing time length condition) includes: the interval between the second time-domain location and the start 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 between the second time-domain location and the start 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 between the second time-domain location and the start position of the second target time-domain resource is less than the second processing time length.

[0137] In some embodiments, the second condition (or second processing time length condition) includes: the interval between the second time-domain location 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 location 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 location and the starting position of the first time-domain resource is less than the second processing time length.

[0138] In some embodiments, the second time-domain location includes one of the following: The terminal device receives the last symbol of the PDCCH receiving the first DCI format; The terminal device receives the end position of the time slot containing the last symbol of the PDCCH receiving the first DCI format; The terminal device is configured to receive the last symbol of the PDCCH received for transmitting a first DCI format; that is, the terminal device detects the last symbol of the CORESET of the first DCI format. The terminal device is configured to receive the end position of the time slot containing the last symbol of the PDCCH received in the first DCI format; The effective time of the activated cell DRX is determined according to the first DCI format; for example... Figure 4 The start time of slot m1+6 for downlink activation BWP in the first cell; or Figure 4 The start time of the first time slot of the uplink activated BWP in the second cell; The effective time of deactivation cell DRX is determined based on the first DCI format; for example... Figure 4 The start time of slot m2+6 for downlink activation BWP in the first cell; or Figure 4 The start time of the second time slot of the uplink activation BWP in the second cell; The effective time of the first DCI format; for example, the starting position of slot m+d on the downlink active BWP of the first cell as determined according to Table 1; or the starting position of the first slot; The first DCI format is used to indicate whether to activate or deactivate the cell DRX, and / or the first DCI format is used to indicate whether the cell enters a network power-saving mode, for example, to indicate that the cell is turned off.

[0139] In some embodiments, the second processing time length and the first processing time length may be the same or different, and this application does not limit this.

[0140] The following example illustrates this point, using the case where all time-domain resources in the first time-domain resource belong to the inactive period of the cell's DRX. Figure 8 As shown, the first time-domain resource is the time-domain resource pre-configured by the terminal device for uplink channels or signals. It originally does not belong to the inactive period of the cell's DRX, but the terminal device determines that the first time-domain resource belongs to the inactive period of the cell's DRX based on the received first DCI format used to indicate the activation of the cell's 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 time interval between the second time-domain position and the start position of the first time-domain resource meets the second processing time length condition. Specifically, if the second time-domain position is within the second processing time length associated with the first time-domain resource, then the terminal device sends the first uplink transmission; otherwise, the terminal device does not send the first uplink transmission.

[0141] Another example is given below. The first time-domain resource is time slot m, which is the resource that the terminal device is configured to use for transmitting pre-configured PUSCH or PUCCH. Taking CG-PUSCH as an example, such as... Figure 9As shown, time slot m does not originally belong to the inactive period of the cell DRX. When the terminal device receives DCI format 2_9 indicating the activation of the cell DRX, and determines based on DCI format 2_9 that time slot m belongs to the inactive period of the 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 it can use time slot m to send CG-PUSCH based on whether the time interval between the received time domain position of DCI format 2_9 and the start position of time slot m meets the second processing time length (e.g., Tpro,2 length). When the time interval between the received end position of DCI format 2_9 and the start position of time slot m is greater than or equal to the Tpro,2 length, the terminal device does not send CG-PUSCH on time slot m; or, if the terminal device has already started preparing to send CG-PUSCH on time slot m, when the time interval between the received end position of DCI format 2_9 and the start position of time slot m is less than the Tpro,2 length, the terminal device can send CG-PUSCH on time slot m. In some embodiments, the length of Tpro,2 is determined based on the time interval required for the terminal device to switch BWP.

[0142] Here is another example. The first time-domain resource is time slots m, m+1, m+2, m+3, which are resources configured by the terminal device for repeatedly transmitting pre-configured PUSCH or PUCCH. In this example, it is assumed that if some or all of the resources in the first time-domain resource overlap with the time-domain resources of the cell DRX's inactive period, the terminal device should not transmit the pre-configured PUSCH or PUCCH through the first time-domain resource. Taking CG-PUSCH as an example, such as... Figure 10 As shown, the first time-domain resource originally does not belong to the inactive period of the cell DRX. When the terminal device receives DCI format 2_9 indicating the activation of the cell DRX, it can determine based on this DCI format 2_9 that some resources in the first time-domain resource belong to the inactive 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 it can use the first time-domain resource to send CG-PUSCH based on whether the time interval between the received time-domain position of DCI format 2_9 and the position of the first time-domain resource meets the second processing time length (e.g., Tpro,2 length). In case 1, the time interval between the received end position of DCI format 2_9 and the start position of the first time-domain resource is greater than or equal to the Tpro,2 length. 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 received end position of DCI format 2_9 and the start position of the first time-domain resource is less than the Tpro,2 length. In this case, in an optional implementation, the terminal device can send CG-PUSCH on the first time-domain resource, such as... Figure 10 As shown in case 2-1; in another optional implementation, the terminal device can send CG-PUSCH on time slots (i.e., time slot m) in the first time domain resources that do not satisfy the Tpro,2 length, and not send CG-PUSCH on time slots (i.e., time slots m+1, m+2, m+3) in the first time domain resources, as shown in case 2-1. Figure 10 The situation is shown in 2-2.

[0143] The technical solution provided in this application provides a solution for handling uplink transmission when the uplink transmission time domain resources occupied by the terminal device partially or completely overlap with the time domain resources occupied by the inactive period of the cell DRX after the terminal device is configured with cell DRX. The terminal device can send the uplink transmission on some time domain resources and / or not send the uplink transmission on some time domain resources, ensuring that the network device and the terminal device have a consistent understanding of the uplink channel or signal to be transmitted, and improving the reliability of uplink transmission.

[0144] In addition, in a network energy-saving system, when a terminal device is configured with cell DRX, if the time domain resources occupied by the uplink transmission of the terminal device (pre-configured uplink transmission and / or dynamically scheduled uplink transmission) partially or completely overlap with the time domain resources occupied by the inactive period of cell DRX, according to the method in this application, the terminal device can send the uplink transmission or cancel the uplink transmission if the processing time conditions are met, thereby avoiding additional terminal device costs.

[0145] Please refer to Figure 11 This illustrates a flowchart of a wireless communication method provided in another embodiment of this application. The method can be performed by a network device. The method may include the following steps: Step 1110: The first uplink transmission of the terminal device occupies the first time domain resource. The second time domain resource is the part of the first time domain resource that overlaps with the time domain resource of the inactive 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.

[0146] In some embodiments, the first uplink transmission includes a pre-configured uplink channel or signal. For an explanation of the pre-configured uplink channel or signal, please refer to the embodiments described above; further details will not be repeated here.

[0147] In some embodiments, the first uplink transmission includes a dynamically scheduled uplink channel or signal. For an explanation of the dynamically scheduled uplink channel or signal, please refer to the embodiments described above; further details will not be repeated here.

[0148] The behavior of the network device will be described below for two scenarios: 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.

[0149] (1) The first uplink transmission includes a pre-configured uplink channel or signal.

[0150] When the first uplink transmission includes a pre-configured uplink channel or signal, the network device does not receive the first uplink transmission on the second target time domain resource. This includes: 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 the positional relationship between the first and second time domain resources (as described in cases 1 to 4 above), when the first uplink transmission includes a pre-configured uplink channel or signal, the network device does not receive the first uplink transmission on the second time domain resource.

[0151] In some embodiments, the network device does not receive the first uplink transmission on the first time domain resource, wherein the second target time domain resource includes the first time domain resource. In this case, the network device not receiving the first uplink transmission on the second time domain resource includes: the network device not receiving the first uplink transmission on the first time domain resource. That is, as long as a portion of the resources in the first time domain resource belongs to the inactive period of the cell's DRX, the network device does not receive the first uplink transmission on the first time domain resource.

[0152] In some embodiments, the network device receives a 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 time domain resources other than the second time domain resources in the first time domain resources. That is, the network device does not receive the first uplink transmission on time domain resources in the first time domain resources that belong to the inactive period of the cell DRX, and receives the first uplink transmission on time domain resources in the first time domain resources that do not belong to the inactive period of the cell DRX.

[0153] In some embodiments, the network device receives a first uplink transmission on time domain resources that precede the second time domain resource in the first time domain resource, and does not receive the first uplink transmission on time domain resources that follow the second time domain resource in the first time domain resource. The first target time domain resource includes time domain resources that precede the second time domain resource in the first time domain resource, and the second target time domain resource includes time domain resources that follow the second time domain resource in the first time domain resource. For example, in case 1, the network device receives the first uplink transmission on time domain resources within the active period of the cell DRX in the first time domain resource (i.e., time domain resources from t1 to t2). In case 2, the network device receives the first uplink transmission on time domain resources within the active period of the preceding cell DRX in the first time domain resource (i.e., time domain resources from t1 to t2), and does not receive the first uplink transmission on time domain resources within the active period of the following cell DRX in the first time domain resource (i.e., time domain resources from t7 to t8). In scenario 4, the network device does not receive the first uplink transmission on the time-domain resources within the active period of the cell DRX (i.e., time-domain resources from t7 to t9). In other words, if the time-domain resources within the inactive period of the cell DRX are located at the beginning of the first time-domain resource, the network device receives the first uplink transmission; if the time-domain resources within the inactive period of the cell DRX are located at the end of the first time-domain resource, the network device does not receive the first uplink transmission.

[0154] In some embodiments, the network device does not receive the first uplink transmission on time domain resources that precede the second time domain resource in the first time domain resource, and receives the first uplink transmission on time domain resources that follow the second time domain resource in the first time domain resource. The first target time domain resource includes time domain resources that follow the second time domain resource in the first time domain resource, and the second target time domain resource includes time domain resources that precede the second time domain resource in the first time domain resource. For example, in case 1, the network device does not receive the first uplink transmission on time domain resources within the activation period of the cell DRX in the first time domain resource (i.e., time domain resources from t1 to t2). In case 2, the network device does not receive the first uplink transmission on time domain resources within the activation period of the preceding cell DRX in the first time domain resource (i.e., time domain resources from t1 to t2), and receives the first uplink transmission on time domain resources within the activation period of the following cell DRX in the first time domain resource (i.e., time domain resources from t7 to t8). In scenario 4, the network device receives the first uplink transmission on the time-domain resources within the active period of the cell DRX (i.e., time-domain resources from t7 to t9). That is, if the time-domain resources within the inactive period of the cell DRX are located at the beginning of the first time-domain resources, the network device does not receive the first uplink transmission; if the time-domain resources within the inactive period of the cell DRX are located at the end of the first time-domain resources, the network device receives the first uplink transmission.

[0155] In some embodiments, when the first uplink transmission includes a pre-configured uplink channel or signal, the network device receives the first uplink transmission on a first target time domain resource, including: in the absence of a second time domain resource, 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. That is, as long as the first time domain resource does not belong to the inactive period of the cell's DRX, the network device must receive the first uplink transmission on the first time domain resource.

[0156] In some embodiments, the terminal device does not send the first uplink transmission, including at least one of the following: the terminal device cancels sending the first uplink transmission, or the terminal device is not prepared to send the first uplink transmission.

[0157] (2) The first uplink transmission includes dynamically scheduled uplink channels or signals.

[0158] 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 receiving 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 the positional relationship between the first time domain resource and the second time domain resource in any of the above situations 1 to 4, the network device receives the first uplink transmission when the first uplink transmission includes a dynamically scheduled uplink channel or signal.

[0159] In the case where the first uplink transmission includes a pre-configured 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: Receive PUCCH carrying HARQ-ACK information; Receive a pre-configured PUSCH, which carries HARQ-ACK information.

[0160] In some embodiments, when the first uplink transmission includes a pre-configured PUSCH and a PUCCH carrying HARQ-ACK information that are time-overlapping, the terminal device transmits the PUCCH carrying HARQ-ACK information; correspondingly, the network device receives the PUCCH carrying HARQ-ACK information.

[0161] In some embodiments, when the first uplink transmission includes a pre-configured PUSCH and a PUCCH carrying HARQ-ACK information that are time-overlapping, the terminal device transmits the pre-configured PUSCH carrying HARQ-ACK information; correspondingly, the network device receives the pre-configured PUSCH carrying HARQ-ACK information.

[0162] In some embodiments, when it is determined from the first configuration information that HARQ-ACK information and pre-configured PUSCH are not reused, a PUCCH carrying HARQ-ACK information is transmitted; accordingly, the network device receives the PUCCH carrying HARQ-ACK information.

[0163] In some embodiments, when HARQ-ACK information and pre-configured PUSCH are multiplexed according to the first configuration information, the pre-configured PUSCH is transmitted, which carries HARQ-ACK information; correspondingly, the network device receives the pre-configured PUSCH, which carries HARQ-ACK information.

[0164] In some embodiments, when the inactive period of a cell DRX is determined by the DCI format, or when the cell DRX is activated or deactivated using the DCI format is determined according to the second configuration information, a PUCCH carrying HARQ-ACK information is transmitted; accordingly, the network device receives the PUCCH carrying HARQ-ACK information.

[0165] In some embodiments, when the inactivity period of a cell DRX is determined by the DCI format, or when it is determined by the second configuration information to activate or deactivate the cell DRX using the DCI format, a pre-configured PUSCH is transmitted, which carries the HARQ-ACK information; correspondingly, the network device receives the pre-configured PUSCH, which carries the HARQ-ACK information.

[0166] In some embodiments, when the inactive period of cell DRX is determined by RRC signaling, or when it is determined by third configuration information to configure cell DRX using RRC signaling, a PUCCH carrying HARQ-ACK information is transmitted; accordingly, the network device receives the PUCCH carrying HARQ-ACK information.

[0167] In some embodiments, when the inactive period of cell DRX is determined by RRC signaling, or when it is determined by third configuration information to configure cell DRX using RRC signaling, a pre-configuration PUSCH is transmitted, which carries HARQ-ACK information; accordingly, the network device receives the pre-configuration PUSCH, which carries HARQ-ACK information.

[0168] In some embodiments, the network device receives a PUCCH carrying HARQ-ACK information, including: if a pre-configured PUSCH and a PUCCH carrying HARQ-ACK information overlap on a third time-domain resource, and if 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. Alternatively, if a pre-configured PUSCH and a PUCCH carrying HARQ-ACK information overlap on a third time-domain resource, and if 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. The first target time-domain resource includes the third time-domain resource.

[0169] 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 HARQ-ACK information but does not receive the pre-configured PUSCH.

[0170] 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, and if 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 pre-configured PUSCH. The network device not receiving the pre-configured PUSCH can mean that the network device does not receive the pre-configured PUSCH on the third time-domain resource, or on the second time-domain resource, or on the first time-domain resource.

[0171] 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, and if 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 not receiving the pre-configured PUSCH can be done by the network device not receiving the pre-configured PUSCH on the third time-domain resource, or not receiving the pre-configured PUSCH on the second time-domain resource, or not receiving the pre-configured PUSCH on the first time-domain resource.

[0172] 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, and if 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 cell DRX's inactive period, the terminal device still multiplexes the HARQ-ACK information onto the pre-configured PUSCH for transmission, and correspondingly, the network device receives the pre-configured PUSCH carrying HARQ-ACK information.

[0173] In some embodiments, the network device receives a pre-configured PUSCH carrying HARQ-ACK information, including: if the pre-configured PUSCH and the PUSCH carrying HARQ-ACK information overlap on a third time-domain resource, and if the third time-domain resource partially or completely overlaps with the second time-domain resource, the network device receives the pre-configured PUSCH carrying HARQ-ACK information on the third time-domain resource. Alternatively, if the pre-configured PUSCH and the PUSCH carrying HARQ-ACK information overlap on a third time-domain resource, and if 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. The first target time-domain resource includes the third time-domain resource.

[0174] 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 carrying HARQ-ACK information.

[0175] 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, and if the third time domain resource partially or completely overlaps with the second time domain resource, 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 time domain resources other than the third time domain resource in the second time domain resource.

[0176] 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, and if 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.

[0177] 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 based on first configuration information sent by the network device. In some embodiments, the first configuration information is used to configure whether HARQ-ACK information and the pre-configured PUSCH are multiplexed during the inactive period of the cell DRX. In some embodiments, when it is determined according to the first configuration information that HARQ-ACK information and the pre-configured PUSCH are not multiplexed, the terminal device transmits a PUCCH carrying HARQ-ACK information but does not transmit the pre-configured PUSCH; correspondingly, the network device receives the PUCCH carrying HARQ-ACK information but does not receive the pre-configured PUSCH. In some embodiments, when it is determined according to the first configuration information that HARQ-ACK information and the pre-configured PUSCH are multiplexed, the terminal device transmits a pre-configured PUSCH carrying HARQ-ACK information; correspondingly, the network device receives the pre-configured PUSCH carrying HARQ-ACK information.

[0178] 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 during 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 network device receives the PUCCH carrying HARQ-ACK information and does not receive the pre-configured PUSCH; 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 network device receives the pre-configured PUSCH carrying HARQ-ACK information.

[0179] In some embodiments, when the terminal device is configured to activate or deactivate a cell DRX in DCI format, if the first uplink transmission includes a pre-configured PUSCH and a PUCCH carrying HARQ-ACK information, the terminal device transmits the PUCCH carrying HARQ-ACK information but does not transmit the pre-configured PUSCH; correspondingly, the network device receives the PUCCH carrying HARQ-ACK information but does not receive the pre-configured PUSCH.

[0180] In some embodiments, if the network device configures the DCI format to activate or deactivate the cell DRX for the terminal device, when the pre-configured PUSCH and the PUCCH carrying HARQ-ACK information overlap in the time domain, the network device will never consider the multiplexing of the pre-configured PUSCH and the PUCCH carrying HARQ-ACK information, that is, the network device will always receive the PUCCH carrying HARQ-ACK information.

[0181] In some embodiments, if the cell DRX is configured by the network device via RRC signaling, when the pre-configured PUSCH and the PUCCH carrying HARQ-ACK information overlap in the time domain during the inactive period of the cell DRX, the network device does not consider the multiplexing of the pre-configured PUSCH and the PUCCH carrying HARQ-ACK information, that is, the network device receives the PUCCH carrying HARQ-ACK information during the inactive period of the cell DRX.

[0182] As explained in the above embodiments, the terminal device's decision to send or not send the first uplink transmission is also subject to the influence of the first condition and / or the second condition.
