[0002] In the NR (New Radio) system, in order to achieve network energy saving, the network device can configure cell DTX (cell Discontinuous Transmission) and / or cell DRX (cell Discontinuous Reception) configuration for the terminal device. During the non-activation period of the cell DTX configured for the terminal device, the network device may not send a specific downlink channel or signal, and / or the terminal device may not receive a specific downlink channel or signal. During the non-activation period of the cell DRX configured for the terminal device, the terminal device may not send a specific uplink channel or signal, and / or the network device may not receive a specific uplink channel or signal.

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

[0042] The embodiments of the present application can be applied to both non-terrestrial networks (NTN) and terrestrial networks (TN). NTNs generally use satellite communications to provide communication services to terrestrial users. Currently, NTN systems include NR-NTN and IoT-NTN systems, and may include other NTN systems in the future.

[0043] For example, Figure 1 is a schematic diagram of the architecture of a communication system provided in an embodiment of the present application. As shown in Figure 1, communication system 100 may include network device 110, which may be a device that communicates with terminal device 120.

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

[0049] The network equipment mentioned in the embodiments of the present application may be an access network device, which may be located on the ground or on a satellite. An access network device is a device deployed in an access network to provide wireless communication functions for terminal devices. Access network devices may include various forms of macro base stations, micro base stations, relay stations, access points, and the like.

For the convenience of description, in the embodiments of the present application, the above-mentioned devices that provide wireless communication functions for terminal devices are collectively referred to as access network devices. Optionally, a communication relationship can be established between a terminal device and a core network device through the access network device.

[0050] The "5G NR system" in the embodiments of the present application may also be referred to as a 5G system or an NR system, but those skilled in the art will understand its meaning. The technical solutions described in the embodiments of the present application may be applicable to LTE systems, 5G NR systems, subsequent evolution systems of 5G NR systems (e.g., B5G systems, 6G systems), and other communication systems such as NB-IoT (Narrow Band Internet of Things) systems, and this application does not limit this.

[0051] In an embodiment of the present application, the network device can provide services for a cell, and the terminal device communicates with the network device through the transmission resources (for example, frequency domain resources, or spectrum resources) on the carrier used by the cell. The cell can be a cell corresponding to the network device (for example, a base station). The cell can belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0052] Before introducing the technical solutions of this application, we first introduce and explain the related technologies involved in this application. The following related technologies can be combined with the technical solutions of the embodiments of this application as optional solutions, and they all fall within the scope of protection of the embodiments of this application. The embodiments of this application include at least part of the following contents.

[0053] 1. Network energy saving

[0054] Network energy conservation is crucial for environmental sustainability, reducing environmental impact (e.g., greenhouse gas emissions), and saving operating costs. As 5G becomes increasingly widespread across various industries and geographic regions, it will need to support very high data rates to handle more advanced services and applications (such as XR). Network deployments will become denser, using more antennas, greater bandwidth, and more frequency bands. Given the environmental impact of 5G, new, controlled solutions are needed to enhance network energy conservation.

[0055] Energy consumption has become a key component of operators' operational expenditures (OPEX). According to a report by the GSMA (Global System for Mobile communications Association), energy costs for mobile networks account for approximately 23% of total OPEX. Most of this energy consumption comes from the radio access network, more specifically, the active antenna unit (AAU), with data centers and fiber optic transmission contributing to a smaller share. The power consumption of a single radio access can be divided into two parts: the dynamic part includes only the power consumption when data is being sent or received; the static part includes the power consumption required to maintain the necessary operations of the radio access equipment at all times, including when no data is being sent or received.

[0056] Therefore, based on the above objectives, it is necessary to research and develop network energy consumption models, KPIs (Key Performance Indicators), and evaluation methods for network devices to identify and study network energy-saving technologies for target deployment scenarios. The already defined power consumption models for terminal devices can serve as a reference. This research should focus on how to achieve more efficient dynamic and / or semi-static operations, and consider one or more network energy-saving technologies applied in the time, frequency, spatial, and power domains. This should be combined with potential terminal device feedback support, potential terminal device auxiliary information, and information exchange or coordination between network interfaces to achieve more fine-grained data transmission and / or reception adaptation.

[0057] It is worth noting that this study not only evaluates potential network energy savings but also assesses and balances the impact on network and user performance by observing key performance indicators (KPIs) such as spectral efficiency, capacity, user perceived throughput (UPT), latency, UE power consumption, complexity, handover performance, call drop rate, initial access performance, and SLA security-related KPIs. This study should avoid significantly impacting these KPIs.

[0058] 2. System message transmission in NR system

[0059] In the NR system, the initial access process of the terminal device can be completed by detecting the synchronization signal block (SSB or SS / PBCH block) on the synchronization raster. During the initial access process, the terminal device attempts to search for the SSB through the predefined possible time and frequency positions of the SSB, and obtains time and frequency synchronization, radio frame timing, and cell ID (identifier) ​​through the detected SSB.

[0060] After detecting the SSB, the terminal device can determine the configuration of the Type0-PDCCH CSS (Type0-Physical Downlink Control Channel Common Search Space, Type0-Physical downlink control channel common search space) set through the MIB (Master Information Block) in the SSB. The terminal device can receive the scheduling of the SIB (System Information Block) 1 message by the network device by monitoring the Type0-PDCCH CSS set. Both the MIB message and the SIB1 message include the system configuration information of the serving cell. Furthermore, the terminal device can receive the scheduling of other system messages other than the SIB1 message by the network device by monitoring the Type0A-PDCCH CSS (Type0A-Physical Downlink Control Channel Common Search Space) set, receive the scheduling of paging messages by the network device by monitoring the Type2-PDCCH CSS (Type2-Physical Downlink Control Channel Common Search Space) set, and receive the Paging Early Indication (PEI) information of the paging message sent by the network device by monitoring the Type2A-PDCCH CSS (Type2A-Physical Downlink Control Channel Common Search Space) set.

[0061] The terminal device can also obtain the resource configuration of the PRACH (Physical Downlink Shared Channel) transmission opportunity (PRACH Occasion, RO) during the random access process based on the received cell system message SIB1. The terminal device can request the network device to send a system message based on the RO resources configured by the network device. The system message requested by the terminal device to send to the network device can be other system messages in addition to SIB1, such as SIB2, SIB3, SIB4, SIB5, SIB6, SIB7, SIB8, SIB9, SIB10, SIB11, SIB12, SIB13, SIB14, SIB15, SIB16, SIB17, SIB18, SIB19, SIB20, SIB21, etc.

[0062] 3. Cell DTX and / or cell DRX configuration in NR systems

[0063] In the NR system, in order to achieve network energy saving, the network device can configure cell DTX and / or cell DRX configuration for the terminal device. During the inactive period of cell DTX configured for the terminal device, the network device may not send specific downlink channels or signals, and / or the terminal device may not receive specific downlink channels or signals. During the inactive period of cell DRX configured for the terminal device, the terminal device may not send specific downlink channels or signals, and / or the network device may not receive specific uplink channels or signals. In this way, energy consumption of the network device can be saved.

[0064] Currently, network devices can configure cell DTX and cell DRX independently or simultaneously. Cell DTX and / or cell DRX configuration can be enabled via RRC (Radio Resource Control) signaling and activated or deactivated via DCI (Downlink Control Information) signaling. DCI signaling is carried in DCI format 2_9.

[0065] The effective time of DCI format 2_9 is determined as follows. When the configuration of cell DTX and / or cell DRX is activated or deactivated through DCI signaling, if the terminal device receives a DCI format 2_9 indicating a change in the activation or deactivation status of the cell DTX and / or cell DRX of the second cell on the time slot m on the downlink activation BWP (Bandwidth Part) of the first cell, then the terminal device activates or deactivates the cell DTX and / or cell DRX starting from the first time slot on the downlink activation BWP and / or uplink activation BWP of the second cell according to the indication information, wherein the first time slot is no earlier than the starting position of the time slot m+d on the downlink activation BWP of the first cell, and d is the number of time slots determined according to the subcarrier spacing of the downlink activation BWP of the first cell, and the values ​​are shown in Table 1 below.

[0066] Table 1: Values ​​of d

[0067] As an example, the second cell of the terminal device is configured with cell DRX and is in an unactivated state. When the terminal device receives a first DCI corresponding to DCI format 2_9 on time slot m1 on the downlink activation BWP of the first cell, and the first DCI indicates that the cell DRX of the second cell is activated, the terminal device activates the cell DRX starting from the first time slot on the uplink activation BWP of the second cell according to the indication information, wherein the first time slot is no earlier than the starting position of time slot m1+d on the downlink activation BWP of the first cell; when the terminal device receives a second DCI corresponding to DCI format 2_9 on time slot m2 on the downlink activation BWP of the first cell, and the second DCI indicates that the cell DRX of the second cell is deactivated, the terminal device deactivates the cell DRX starting from the second time slot on the uplink activation BWP of the second cell according to the indication information, wherein the second time slot is no earlier than the starting position of time slot m2+d on the downlink activation BWP of the first cell. Figure 4 shows a schematic diagram of the above-mentioned activation or deactivation of the cell DRX of the second cell through DCI signaling. In Figure 4 , it is assumed that the SCS (Subcarrier Spacing) of the downlink activated BWP of the first cell is 30 kHz, that is, the value of d is 6; and the SCS of the uplink activated BWP of the second cell is 15 kHz. It should be noted that the first cell and the second cell can be the same cell or different cells.

[0068] 4. Paging mechanism in NR system

[0069] NR system paging has three main application scenarios, corresponding to three types of paging messages: core network-initiated paging, gNB-initiated paging, and gNB-initiated system update notifications. gNB-initiated system update notifications are called short messages in the RRC protocol. The PDCCH of these three paging messages is scrambled with the common Paging-Radio Network Temporary Identifier (P-RNTI) configured in the cell. A comparison of these three paging messages is shown in Table 2.

[0070] Table 2

[0071] On the primary cell, the terminal device monitors the Type2-PDCCH CSS set configured in the paging search space (Paging Search Space) according to the CRC (Cyclic Redundancy Check) using the DCI format 1_0 scrambled by P-RNTI to receive the scheduling of the paging message by the network device. Among them, the short message is the RRC information contained in the above-mentioned CRC using the DCI format 1_0 scrambled by P-RNTI. Specifically, the CRC using the DCI format 1_0 scrambled by P-RNTI includes two information fields related to short messages, one is the short message indicator field, and the other is the short message field. The short message indication field includes 2 bits for indicating the information shown in Table 3; the short message field includes 8 bits for indicating the information shown in Table 4. Among them, the short message field is reserved when only the scheduling information of the paging message appears in the DCI, and when the TRS (Tracking Reference Signal) is configured, the TRS availability indication.

[0072] Table 3

[0073] Table 4

[0074] The basic principles of the paging message transmission mechanism are the same for core network-initiated and gNB-initiated paging. From the network's perspective, paging messages are sent at every paging opportunity (PO) within the system message update cycle. From the terminal device's perspective, the UE only monitors one PO during each DRX cycle. Each UE calculates the paging frame (PF) and paging opportunity PO based on its own UE ID (UE Identifier) ​​and DRX cycle. This means that each PO is associated with a specific UE and is not shared by all UEs. Since UEs only need to monitor their own PO, this PO-based grouping mechanism can reduce false alarm rates for paging calls between different POs.

[0075] A PO is a group of PDCCH monitoring opportunities (PDCCH Monitoring Occasions), consisting of multiple time units (such as subframes, time slots, or symbols), which can be used to transmit paging DCI. A PF is a radio frame that can include one or more POs or the starting position of a PO.

[0076] 5. Enhanced paging mechanism in NR system

[0077] The power consumption of terminal devices in the RRC_IDLE and RRC_INACTIVE states mainly comes from periodic discontinuous paging reception. To reduce power consumption during paging reception, an energy-saving signal for paging reception, called Paging Early Indication (PEI), is introduced. It is used to indicate whether the terminal device needs to receive paging on the PO before the PO arrives.

[0078] PEI further introduces the concept of subgrouping within a PO based on the existing PO-based grouping. When only UEs in some subgroups are paged, UEs in other subgroups do not need to wake up to receive paging, so as to achieve the purpose of terminal power saving. The division of subgroups supports UE ID-based grouping and network-allocated grouping. UE ID-based grouping is similar to the way PO is calculated based on UE ID. For example, the system message broadcasts the maximum number of groups in each PO. By performing related operations such as modulo operation of UE ID on this maximum number of groups, the group information to which the UE belongs on this PO can be obtained. In the network-allocated grouping scheme, the terminal device obtains grouping information directly from the network.

[0079] On the primary cell, the terminal device monitors the Type2A-PDCCH CSS set configured in the PEI search space (Pei-Search Space) according to the DCI format 2_7 scrambled with PEI-RNTI according to the CRC to receive the PEI message sent by the network device. The paging indication field in DCI format 2_7 includes NPO*NSG bits, where NPO is the number of POs configured by the high-level parameter po-NumPerPEI, and NSG is the number of subgroups included in a PO configured by the high-level parameter subgroupsNumPerPO. Each bit is used to indicate a terminal subgroup in a PO. The maximum number of subgroups included in a PO is 8.

[0080] The PEI indicates whether terminal devices in the RRC_IDLE and RRC_INACTIVE states need to monitor paging. When a terminal group or terminal subgroup requires monitoring paging, the PEI instructs the terminal device to monitor the PO. If no PEI associated with the PO is detected, the terminal does not need to monitor the PO. Network devices can provide PEI configuration information through system messages.

[0081] The UE monitors only one PEI-O in each DRX cycle. A PEI Occasion (PEI-O) is a collection of multiple PDCCH monitoring opportunities. A PEI monitoring opportunity is a set of PDCCH monitoring opportunities (PDCCH Monitoring Occasions) consisting of multiple time units (e.g., subframes, time slots, or symbols) that can be used to transmit a PEI. In multi-beam operation, the UE assumes that the same PEI is repeated in all transmitted beams. Therefore, the selection of the beam to receive the PEI is up to the UE implementation.

[0082] Please refer to Figure 5, which shows a flow chart of a wireless communication method provided by an embodiment of the present application. The execution subject of each step of the method is a terminal device. The method may include at least one step of steps 510-520.

[0083] Step 510: The terminal device determines the cell DTX configuration and / or cell DRX configuration on the first cell.

[0084] In some embodiments, the terminal device determines the cell DTX configuration and / or cell DRX configuration on the first cell based on the system message.

[0085] In some embodiments, the network device corresponding to the first cell sends first configuration information, and the terminal device receives the first configuration information, where the first configuration information is used to configure the cell DTX configuration and / or cell DRX configuration on the first cell.

[0086] It is understandable that a terminal device in an RRC idle state or an inactive state also needs to monitor or receive a downlink common channel or signal on the first cell, and therefore also needs to obtain the first configuration information for configuring the cell DTX. In order for a terminal device in an idle state or an inactive state to receive the first configuration information, the first configuration information needs to be carried in a system message.

[0087] In step 520, the terminal device determines whether the resources in the inactive period of the cell DTX can be used to transmit downlink common channels or signals, and / or determines whether the uplink common resources in the inactive period of the cell DRX can be used to transmit uplink channels or signals based on the first indication information.

[0088] In some embodiments, the first indication information is used to indicate activation or deactivation of cell DTX and / or cell DRX, wherein the first indication information includes a first bit and / or a second bit.

[0089] In some embodiments, after activating the cell DTX of the first cell, during the inactive period of the cell DTX, the network device does not send a specific downlink channel or signal, and / or the terminal device does not receive a specific downlink channel or signal.

[0090] Please refer to Figure 6, which shows a schematic diagram of system message transmission when cell DTX is activated, according to one embodiment of the present application. In this embodiment, the downlink BWP of the first cell includes resources for periodic transmission of system messages. When cell DTX is configured or activated for the first cell, the resources used for system message transmission are valid during the cell DTX activation period and invalid during the cell DTX inactivation period.

[0091] In some embodiments, after deactivating the cell DTX of the first cell, during the inactive period of the cell DTX, the network device may transmit a specific downlink channel or signal, and / or the terminal device may receive a specific downlink channel or signal.

[0092] In some embodiments, after activating the cell DRX of the first cell, during the inactive period of the cell DRX, the terminal device does not send a specific uplink channel or signal, and / or the network device does not receive a specific uplink channel or signal.

[0093] In some embodiments, after deactivating the cell DRX of the first cell, during the inactive period of the cell DRX, the terminal device may send a specific uplink channel or signal, and / or the network device may receive a specific uplink channel or signal.

[0094] In some embodiments, the first indication information includes a first bit and a second bit. When cell DTX is configured, the first bit is used to indicate activation or deactivation of cell DTX. When cell DRX is configured, the second bit is used to indicate activation or deactivation of cell DRX.

[0095] The above method realizes separate control of activation of cell DTX and cell DRX by setting the first bit and the second bit.

[0096] In some embodiments, the first indication information includes a first bit and a second bit. When only cell DTX is configured, the first bit is used to indicate activation or deactivation of cell DTX. When only cell DRX is configured, the first bit is used to indicate activation or deactivation of cell DRX. When both cell DTX and cell DRX are configured, the first bit is used to indicate activation or deactivation of cell DTX, and the second bit is used to indicate activation or deactivation of cell DRX.

[0097] In the above method, only when cell DTX and cell DRX are configured at the same time, the first bit and the second bit are used simultaneously, thereby achieving separate control over activation of cell DTX and cell DRX and reducing data redundancy.

[0098] In some embodiments, the first indication information includes a first bit. When only cell DTX is configured, the first bit is used to indicate activation or deactivation of cell DTX. When only cell DRX is configured, the first bit is used to indicate activation or deactivation of cell DRX. When both cell DTX and cell DRX are configured, the first bit is used to indicate activation or deactivation of both cell DTX and cell DRX.

[0099] In the above method, unified management of activation of cell DTX and cell DRX is achieved through the first bit, which reduces data redundancy and saves transmission resources.

[0100] In some embodiments, the first indication information is carried in a first PDCCH (Physical Downlink Control Channel) format, the first PDCCH format is scrambled by a first RNTI (Network Temporary Identifier), and the first RNTI is configured by the network device.

[0101] That is, the CRC of the first PDCCH format is scrambled using the first RNTI.

[0102] In some embodiments, the above-mentioned network device is a network device corresponding to the first cell.

[0103] In some embodiments, the above-mentioned network device is a cell other than the first cell, such as a network device corresponding to the second cell.

[0104] The first RNTI may be any type of RNTI configured by the network device. PDCCHs of different formats are scrambled by different types of RNTIs.

[0105] In some embodiments, the first PDCCH format is transmitted via a first common search space set, where the first common search space set is configured by the network device.

[0106] The first common search space set may be any CSS set configured on the network device.

[0107] In some embodiments, during an inactive period of cell DTX, the terminal device monitors the first PDCCH format through a first common search space set.

[0108] In some embodiments, the terminal device may obtain the first indication information by monitoring the first PDCCH format.

[0109] In some embodiments, during the inactive period of cell DTX, the terminal device does not monitor the first PDCCH format.

[0110] In some embodiments, the terminal device may obtain the first indication information by monitoring a PDCCH format other than the first PDCCH format.

[0111] Since the transmission of paging-related messages is not affected by the network energy-saving configuration (such as cell DTX configuration, etc.), the downlink channel or signal associated with the transmission of paging-related messages can be enhanced to enable the terminal device to know whether the network device uses the time domain resources within the non-activation period of the cell DTX to send downlink common channels or signals.

[0112] In some embodiments, the first indication information is carried in a second PDCCH format, the second PDCCH format is scrambled by a P-RNTI, and the P-RNTI is an RNTI used for scheduling paging messages.

[0113] That is, the CRC of the second PDCCH format is scrambled using the P-RNTI.

[0114] In some embodiments, the second PDCCH format is transmitted via a second common search space set. The second common search space set is a CSS of a PDCCH format that can be used to transmit a P-RNTI scrambling code. For example, the second common search space set can be a Type 2-PDCCH CSS configured by the network device.

[0115] In some embodiments, during an inactive period of cell DTX, the terminal device monitors the second PDCCH format through a second common search space set.

[0116] In some embodiments, the terminal device may obtain the first indication information by monitoring the second PDCCH format.

[0117] In some embodiments, the first indication information is an independent information field in the second PDCCH format.

[0118] In some embodiments, there are still reserved bits in the second PDCCH format (eg, P-RNTI scrambled DCI format 1_0), so an information field may be added to the second PDCCH format to serve as the above-mentioned independent information field.

[0119] In some embodiments, the first indication information multiplexes the information field in the second PDCCH format.

[0120] In some embodiments, the first indication information multiplexes the short message indication field or the short message field in the second PDCCH format.

[0121] In some embodiments, at least one bit in the first indication information is carried in a short message field in the second PDCCH format.

[0122] In some embodiments, when the short message indication field in the second PDCCH format indicates that a short message appears in the second PDCCH format, at least one bit in the first indication information carries the short message field in the second PDCCH format.

[0123] Exemplarily, when the short message indication field in the second PDCCH format indicates "10" or "11", the first indication information includes bit 5 and / or bit 6 in the short message field.

[0124] In some embodiments, the terminal device determines, based on configuration information of the network device, that at least one bit in the first indication information is carried in a short message field in the second PDCCH format.

[0125] In some embodiments, the first bit is bit 5 in the short message field.

[0126] In some embodiments, when configuring cell DTX, bit 5 is used to indicate activation or deactivation of cell DTX.

[0127] In some embodiments, the second bit is bit 6 in the short message field.

[0128] In some embodiments, when configuring cell DRX, bit 6 is used to indicate activation or deactivation of cell DRX.

[0129] Exemplarily, when only cell DTX is configured, the first indication information includes bit 5 in the short message indication field, which is used to indicate the activation or deactivation of cell DTX; or, when only cell DRX is configured, the first indication information includes bit 5 in the short message indication field, which is used to indicate the activation or deactivation of cell DRX; or, when cell DTX and cell DRX are configured at the same time, the first indication information includes bit 5 and bit 6 in the short message indication field, which is used to indicate the activation or deactivation of cell DTX, and bit 6 is used to indicate the activation or deactivation of cell DRX.

[0130] Exemplarily, the first indication information includes bit 5 in the short message indication field. When only cell DTX is configured, bit 5 is used to indicate activation or deactivation of cell DTX; or, when only cell DRX is configured, bit 5 is used to indicate activation or deactivation of cell DRX; or, when cell DTX and cell DRX are configured at the same time, bit 5 is used to indicate activation or deactivation of cell DTX and cell DRX.

[0131] In addition, it should be noted that the above-mentioned first bit is bit 5 in the short message domain, and the second bit is bit 6 in the short message domain. This is only a possible implementation scheme of the present application. In some embodiments, the first bit can be bit 6 in the short message domain, and the second bit can be bit 5 in the short message domain, or the first bit and the second bit can also be other reserved bits in the short message domain, such as bit 7 and bit 8.

[0132] In some embodiments, the first indication information is carried in a third PDCCH format, the third PDCCH format is scrambled by PEI-RNTI (Paging Advance Indication-Radio Network Temporary Identity), and PEI-RNTI is an RNTI used for early indication of paging messages.

[0133] That is, the CRC of the third PDCCH format uses PEI-RNTI scrambling.

[0134] In some embodiments, the third PDCCH format is transmitted via a third common search space set. The third common search space set is a CSS of a PDCCH format that can be used to transmit a PEI-RNTI scrambling code. For example, the third common search space set can be a Type 2A-PDCCH CSS configured by the network device.

[0135] In some embodiments, during an inactive period of cell DTX, the terminal device monitors a third PDCCH format through a third common search space set.

[0136] In some embodiments, the terminal device may obtain the first indication information by monitoring the third PDCCH format.

[0137] In some embodiments, the position of the start bit in the first indication information in the third PDCCH format is configured by the network device.

[0138] In some embodiments, the first indication information is an independent information field in the third PDCCH format. That is, there are still reserved bits in the third PDCCH format (such as the DCI format of the PEI-RNTI scrambled code), so an information field can be added to the third PDCCH format to serve as the above-mentioned independent information field.

[0139] In some embodiments, the first indication information multiplexes an information field in a third PDCCH format. Exemplarily, the first indication information multiplexes a paging indication information field in the third PDCCH format. For example, when the paging indication information field in the third PDCCH format indicates that all preset values ​​are "1," it indicates that time domain resources within the DTX inactive period of the cell can be used to transmit downlink common channels or signals.

[0140] In some embodiments, if the first indication information indicates activation of the cell DTX, the terminal device determines that resources in the inactive period of the cell DTX cannot be used to transmit downlink common channels or signals.

[0141] In some embodiments, if the first indication information indicates deactivation of the cell DTX, the terminal device determines that resources within the non-activation period of the cell DTX can be used to transmit downlink common channels or signals.

[0142] In some embodiments, if the first indication information indicates activation of the cell DRX, the terminal device determines that the uplink common resources in the inactive period of the cell DRX cannot be used to transmit uplink channels or signals.

[0143] In some embodiments, if the first indication information indicates deactivation of the cell DRX, the terminal device determines that the uplink common resources within the inactive period of the cell DRX can be used to transmit uplink channels or signals.

[0144] In some embodiments, if the terminal device does not receive the first indication information, it determines that the resources within the non-activation period of the cell DTX cannot be used to transmit downlink common channels or signals, and / or determines that the uplink common resources within the non-activation period of the cell DRX cannot be used to transmit uplink channels or signals.

[0145] It is understandable that when the terminal device does not receive the first indication information, the terminal device's behavior needs to be regulated. In the above method, when the terminal device does not receive the first indication information, it can directly determine that the transmission resources in the inactive period are unavailable. This avoids unnecessary data processing by the terminal device.

[0146] In some embodiments, if the terminal device does not receive the first indication information, it determines that the resources within the non-activation period of the cell DTX can be used to transmit downlink common channels or signals, and / or determines that the uplink common resources within the non-activation period of the cell DRX can be used to transmit uplink channels or signals.

[0147] In the above method, when the terminal device does not receive the first indication information, it can directly determine that transmission resources are available during the inactive period. In other words, in the above method, the reception of the first indication information is a continuous process. Therefore, when the transmission of the first indication information is suspended, the terminal device can quickly determine that transmission resources are available, thereby improving the timeliness of the transmission of certain specific messages, such as updated system messages.

[0148] In some embodiments, if the terminal device does not receive the first indication information, the behavior of the terminal device is not changed. That is, if it is previously determined that the resources within the non-activation period of the cell DTX can be used to transmit downlink common channels or signals, and / or, it is determined that the uplink common resources within the non-activation period of the cell DRX can be used to transmit uplink channels or signals, then it is still determined that the resources within the non-activation period of the cell DTX can be used to transmit downlink common channels or signals, and / or, it is determined that the uplink common resources within the non-activation period of the cell DRX can be used to transmit uplink channels or signals. If it is previously determined that the resources within the non-activation period of the cell DTX cannot be used to transmit downlink common channels or signals, and / or, it is determined that the uplink common resources within the non-activation period of the cell DRX cannot be used to transmit uplink channels or signals, then it is still determined that the resources within the non-activation period of the cell DTX cannot be used to transmit downlink common channels or signals, and / or, it is determined that the uplink common resources within the non-activation period of the cell DRX cannot be used to transmit uplink channels or signals.

[0149] In the above method, when the terminal device does not receive the first indication information, the behavior of the terminal device remains unchanged for the transmission resources in the inactive period. In other words, if the terminal device does not receive the first indication information, no additional processing is required, and the implementation is simple.

[0150] In some embodiments, the first indication information is used to determine whether to trigger a system message update. In some embodiments, the first indication information is carried in a second PDCCH format, the second PDCCH format is scrambled by a P-RNTI, and the P-RNTI is an RNTI used to schedule paging messages. Alternatively, the first indication information is carried in a third PDCCH format, the third PDCCH format is scrambled by a PEI-RNTI, and the PEI-RNTI is an RNTI used to indicate a paging message in advance.

[0151] In some embodiments, when determining to trigger a system message update based on the first indication information, the terminal device determines that resources within the inactive period of the cell DTX can be used to transmit a downlink common channel or signal.

[0152] In some embodiments, when the short message indication field in the second PDCCH format indicates "10" or "11", it indicates a triggered system message update, and the terminal device determines that resources within the non-activation period of the cell DTX can be used to transmit downlink common channels or signals.

[0153] In some embodiments, when the short message indication field in the second PDCCH format indicates "10" or "11" and the short message field indicates "1" or "2" or "4", it indicates a triggered system message update, and the terminal device determines that the resources within the non-activation period of the cell DTX can be used to transmit downlink common channels or signals.

[0154] In some embodiments, when the short message field in the second PDCCH format indicates "1" or "2" or "4", it indicates a triggered system message update, and the terminal device determines that resources within the non-activation period of the cell DTX can be used to transmit downlink common channels or signals.

[0155] That is to say, in the scenario of system message changes, in order to enable the terminal device to obtain the updated system message as soon as possible, the network device is not affected by the configured cell DTX when transmitting the system message, that is, the network device can still transmit the system message on the time domain resources within the inactive period of the cell DTX.

[0156] For example, please refer to Figure 7. In the first cell, cell DTX is configured through a system message. During the activation period of cell DTX, the network device normally transmits the system message in the first cell. During the inactivation period of cell DTX, the network device does not transmit the system message in the first cell. When the network device needs to update the system message in the first cell, the network device indicates the system message change in the first cell to the terminal device through the PDCCH scrambled by the P-RNTI. After receiving the system message change message (i.e., the first indication information), the terminal device determines that the resources in the inactivation period of cell DTX can be used to transmit downlink common channels or signals. In other words, the terminal device can receive the system message in the first cell transmitted by the network device during the inactivation period of cell DTX.

[0157] It can be seen that the above method can enable terminal devices to quickly obtain updated system information even in a network energy-saving scenario, thereby improving network communication performance.

[0158] In some embodiments, when determining to trigger a system message update based on the first indication information, the terminal device determines that uplink common resources within the inactive period of the cell DRX can be used to transmit uplink channels or signals.

[0159] In some embodiments, the effective time of the first indication information is determined according to the time when the first indication information is received.

[0160] In some embodiments, the effective time of the first indication information is the first time unit after the first indication information is received and a delay time length has elapsed. The time unit may be a time slot, a subframe, or a symbol. The delay time length is predefined or configured by the network device. For example, the value of the delay time length is shown in Table 1, where the SCS in Table 1 is the SCS corresponding to the channel carrying the first indication information.

[0161] As an example, the method for determining the effective time of the first indication information is the same as the method for determining the effective time of the aforementioned DCI format 2_9, which will not be repeated here.

[0162] In some embodiments, the downlink common channel or signal includes one or more of the following: SSB, SIB1, a first system message, a second system message, a PDCCH scheduling SIB1, CSI-RS (Channel State Information-Reference Signal), TRS, PRS (Positioning Reference Signal); wherein, the first system message includes SIB6, SIB7 and SIB8, and the second system message includes other system messages except SIB6, SIB7 and SIB8.

[0163] In some embodiments, the uplink channel or signal includes one or more of the following: PRACH, MsgA (Message A).

[0164] In some embodiments, the downlink common channel or signal further includes one or more of the following: a paging message, a PDCCH for scheduling a paging message, and a PEI.

[0165] In some embodiments, the downlink common channel or signal does not include one or more of the following: paging messages, PDCCH for scheduling paging messages, and PEI. It is understandable that terminal devices in an idle state or an inactive state also need to monitor or receive paging-related messages (such as paging messages, and / or PDCCH for scheduling paging messages, and / or PEI information). For example, when a terminal device in an idle state or an inactive state is called, the network device needs to notify the terminal device through a paging-related message. Therefore, in order to avoid affecting the implementation of terminal devices in an idle state or an inactive state, in some cases, the downlink common channel or signal may not include paging-related messages, or in other words, the time domain resources within the inactive period of the cell DTX can be used to transmit paging-related messages, that is, paging-related messages are not affected by the cell DTX configuration.

[0166] In some embodiments, the first indication information is transmitted via resources in the first cell.

[0167] In some embodiments, the first indication information is transmitted via resources in a second cell, and the second cell is a different cell from the first cell.

[0168] The technical solution provided by the embodiments of the present application is that, after determining the cell DTX configuration and / or cell DRX configuration on the first cell, the terminal device determines, based on first indication information, whether resources within the inactive period of the cell DTX can be used to transmit downlink common channels or signals, and / or whether uplink common resources within the inactive period of the cell DRX can be used to transmit uplink channels or signals. This allows certain specific messages to be transmitted in a timely manner during the inactive period of the cell DTX and / or cell DRX. This improves network communication performance in network energy-saving scenarios.

[0169] Please refer to Figure 8, which shows a flowchart of a wireless communication method provided by another embodiment of the present application. The execution subject of each step of the method is a network device. The method may include at least one step of steps 810-820.

[0170] Step 810: The network device configures a cell DTX configuration and / or a cell DRX configuration on a first cell.

[0171] In some embodiments, the network device configures the cell DTX configuration and / or the cell DRX configuration on the first cell through a system message.

[0172] In step 820, the network device sends a first indication message, which is used by the terminal device to determine whether the resources within the non-activation period of the cell DTX can be used to transmit downlink common channels or signals, and / or to determine whether the uplink common resources within the non-activation period of the cell DRX can be used to transmit uplink channels or signals.

[0173] In some embodiments, the network device corresponding to the first cell sends first indication information, and the terminal device receives the first indication information.

[0185] In some embodiments, when the short message indication field in the second PDCCH format indicates that a short message appears in the second PDCCH format, at least one bit in the first indication information carries the short message field in the second PDCCH format.

[0186] In some embodiments, the terminal device may determine, based on configuration information of the network device, that at least one bit in the first indication information is carried in the short message field in the second PDCCH format. In some embodiments, the network device sends the configuration information, and the terminal device receives the configuration information.
