Description

Technical Field

[0001] This application relates to the field of communications, and more specifically, to a communication method and apparatus. Background Technology

[0002] During communication between terminal devices and network devices, there is not always a need for information exchange between them. If the terminal device continuously monitors the physical downlink control channel (PDCCH), it will generate a large amount of energy consumption.

[0003] Some related solutions propose the discontinuous reception (DRX) mechanism. In the DRX mechanism, network devices can semi-statically configure periodic active and dormant periods for terminal devices, so that the terminal devices only monitor the PDCCH to achieve data transmission during the active period, and do not monitor the PDCCH during the dormant period, thereby reducing the power consumption of the terminal devices.

[0004] However, in actual business operations, the timing of data transmission often changes dynamically, which may cause a mismatch between the timing of data transmission and the activation period of the semi-static configuration of network devices. To match these dynamically changing actual business needs, network devices will assign a longer activation period to terminal devices through semi-static configuration. However, this results in higher power consumption for the terminal devices. Summary of the Invention

[0005] This application provides a communication method and apparatus that helps reduce the energy consumption of terminal devices.

[0006] Firstly, a communication method is provided. The subject executing the method provided in the first aspect can be a first terminal.

[0007] For example, the method includes: receiving a first signaling signal to instruct a first terminal to wait for a first time period of monitoring and control channel; wherein the first signaling signal is a combination of one or more of the following: a first wake-up signal, a system information block, a media access control unit, or first downlink control information.

[0008] Based on the above scheme, the first signaling indicating the first time period can be any one or a combination of the following: a first wake-up signal, a system information block, a media access control unit, or first downlink control information. The processing latency of these information or signals is lower than that of semi-static radio resource control (RRC) signaling, enabling dynamic indication of the first time period. This reduces the power consumption of the first terminal while improving configuration flexibility. For example, in situations where data transmission becomes more centralized, due to the lower processing complexity and latency of the aforementioned first signaling, network devices can promptly instruct the first terminal to use a shorter first time period that matches actual service requirements, thereby further reducing the power consumption of the first terminal while meeting actual service needs.

[0009] In some implementations, the first signaling further includes: indication information for a first timer; wherein the method further includes: starting the first timer if a first condition is met within the first time period.

[0010] Optionally, the first timer is used to determine the end position of the first time period as the end position of the first timer. For example, determining the end position of the first time period as the end position of the first timer may include: adjusting, updating, or extending the end position of the first time period to the end position of the first timer.

[0011] Optionally, the method further includes: waiting to monitor the control channel before the first timer expires.

[0012] Based on the above scheme, the first timer can be used to extend the first time period. This mechanism can adjust the time period for the terminal to monitor and control the channel, thereby helping to meet the needs of actual services. As an example, the first time period can also be implemented using one or more timers.

[0013] In some implementations, the first condition includes at least one of the following: the first terminal detects the control channel during the first time period; or, the first terminal fails to decode the received data packets during the first time period.

[0014] It is understandable that the first terminal detecting a control channel often indicates that there is data to be transmitted in actual service. Therefore, when the first terminal detects a control channel, triggering a first timer to extend the time period allows it to receive or send data during the extended period, thus matching the needs of the actual service. Furthermore, if the first terminal fails to decode a received data packet, triggering a first timer to extend the time period allows it to re-receive the undecoded data packet during the extended period, thus facilitating successful decoding and meeting the needs of the actual service.

[0015] In some implementations, before receiving the first signaling, the method further includes: receiving indication information of a second time period during which the first terminal waits to monitor the control channel; wherein the first signaling is used to update the second time period to the first time period.

[0016] Based on the above scheme, the first signaling can dynamically adjust the second time period configured for network devices, adjusting the second time period to the first time period, thereby helping to flexibly match the needs of actual services.

[0017] In some implementations, the first signaling is the first downlink control information received before the first time period; wherein, before receiving the first downlink control information, the method further includes: receiving a second wake-up signal, the second wake-up signal being used to indicate whether the first terminal monitors the first downlink control information associated with the second wake-up signal.

[0018] In some implementations, the first signaling is the first downlink control information received within the first time period. Before the first time period, the method further includes: receiving a second wake-up signal, which is used to indicate whether the first terminal monitors the first downlink control information associated with the second wake-up signal and to indicate the start position of the first time period; wherein the first downlink control information is used to indicate the end position of the first time period.

[0019] In the above scheme, the first terminal can quickly enter the wake-up state via the second wake-up signal and monitor the control channel without indicating the time to end the wake-up state (i.e., the end position of the first time period). Then, the first terminal can receive the first downlink control information while in the wake-up state (i.e., within the first time period) and determine the time to end the wake-up state based on this information. Therefore, the above scheme can flexibly control the duration of the first terminal's wake-up state while ensuring timely wake-up. This helps to flexibly match the needs of actual services.

[0020] In some implementations, the second wake-up signal is also used to instruct the first terminal to monitor second downlink control information for scheduling data transmission on the control channel during the first time period.

[0021] In some implementations, before receiving the first signaling, the method further includes: receiving first configuration information, the first configuration information being used to configure at least one third time period, the at least one third time period corresponding one-to-one with at least one identifier, the at least one third time period including the first time period; wherein, the first signaling includes a first identifier, the first identifier being the identifier among the at least one identifier corresponding to the first time period.

[0022] Based on the above scheme, the network device can reduce the overhead of the first signaling by indicating the first time period used by the first terminal.

[0023] In some implementations, before receiving the first signaling, the method further includes: receiving second configuration information, which is used to configure the first time period and the third time period, and to configure the first terminal to use the third time period to monitor the control channel; wherein the first signaling includes second indication information, which is used to indicate that the time period for the first terminal to wait for monitoring the control channel is switched from the third time period to the first time period.

[0024] Based on the above scheme, network devices can instruct the first terminal to switch the monitoring and control channel time period through the second indication information, thereby supporting flexible changes to the first terminal's monitoring and control channel time period according to service requirements and improving energy efficiency. In some examples, the second indication information can be implemented with 1 bit, resulting in less signaling overhead.

[0025] In some implementations, the first signaling further includes: first indication information, wherein the first indication information is used to indicate: the frequency domain resources of the first terminal that can be used to receive data, and / or the frequency domain resources of the first terminal that can be used to transmit data.

[0026] Based on the above scheme, the network device can activate frequency domain resources and schedule data transmission by issuing the first signaling, which can save signaling overhead and help the first terminal transmit data more quickly.

[0027] In some implementations, the first time period is an active period in a discontinuous reception cycle; or, the first time period belongs to a first set, which includes multiple time periods available for the first terminal to wait for the monitoring and control channel, the multiple time periods being non-interval distributed in the time domain, or the multiple time periods being non-periodic distributed in the time domain, or two of the multiple time periods having different lengths.

[0028] As an example, a non-spaced distribution can be understood as a "continuous distribution".

[0029] In some implementations, the first signaling includes at least one of the following: indication information of the location of the first time period in the time domain; indication information of frequency domain resources used by the first terminal during the first time period; indication information of spatial domain parameters used by the first terminal during the first time period; or, indication information of power domain parameters used by the first terminal during the first time period.

[0030] In some examples, the aforementioned frequency domain resources may be multiple carriers used by the first terminal during the first time period. The indication information of the aforementioned frequency domain resources may indicate or activate the aforementioned multiple carriers.

[0031] In some implementations, the first signaling further includes: indication information of a first offset, wherein the first offset is the offset in the time domain between the time domain resource of the first signaling and the start position of the first time period.

[0032] Based on the above scheme, the starting position of the first time period can be dynamically changed according to the position of the first signaling by using the first offset, thereby flexibly matching the needs of actual services. For example, in the case of actual service jitter, the above scheme can reserve time for the first terminal to process the first signaling.

[0033] In some implementations, the first signaling further includes: indication information for a second offset, wherein the second offset is the offset in the time domain between the end position of the first time period and the time domain resources of the second signaling, the time domain resources of the second signaling are located after the time domain resources of the first signaling, and the second signaling is used to indicate a fourth time period of waiting for the monitoring and control channel.

[0034] Based on the above scheme, by configuring a second offset, the network device can dynamically change the sending and monitoring positions of the second signaling according to the end position of the first time period, thereby flexibly matching the needs of actual services. For example, if the first time period ends early or late, due to the constraint of the second offset, the network device's operation of sending the second signaling will be advanced or delayed accordingly, and the first terminal's operation of monitoring the second signaling will also be advanced or delayed accordingly, thus ensuring that the length of the first terminal's sleep time is at least the second offset, avoiding the loss of emergency services caused by the adjustment of the first time period.

[0035] Secondly, a communication method is provided. The method provided in the second aspect can be implemented by a network-side device.

[0036] For example, the method includes: sending a first signaling message to instruct a first terminal to wait for a first time period of monitoring and control channel; wherein the first signaling message is a combination of one or more of the following: a first wake-up signal, a system information block, a media access control unit, or first downlink control information.

[0037] In some implementations, the first signaling also includes: indication information for a first timer, which is started if a first condition is met within the first time period.

[0038] Optionally, the first timer is used to determine the end position of the first time period as the end position of the first timer.

[0039] In some implementations, before sending the first signaling, the method further includes: sending indication information of a second time period during which the first terminal waits to detect the control channel; wherein the first signaling is used to update the second time period to the first time period.

[0040] In some implementations, the first signaling is the first downlink control information sent before the first time period; wherein, before sending the first downlink control information, the method further includes: sending a second wake-up signal, the second wake-up signal being used to indicate whether the first terminal monitors the first downlink control information associated with the second wake-up signal.

[0041] In some implementations, the first signaling is the first downlink control information sent within the first time period. Before the first time period, the method further includes: sending a second wake-up signal, which is used to indicate whether the first terminal monitors the first downlink control information associated with the second wake-up signal and to indicate the start position of the first time period; wherein the first downlink control information is used to indicate the end position of the first time period.

[0042] In some implementations, before sending the first signaling, the method further includes: sending first configuration information, the first configuration information being used to configure at least one third time period, the at least one third time period corresponding one-to-one with at least one identifier, the at least one third time period including the first time period; wherein, the first signaling includes a first identifier, the first identifier being the identifier among the at least one identifier corresponding to the first time period.

[0043] In some implementations, before sending the first signaling, the method further includes: sending second configuration information, which is used to configure the first time period and the third time period, and to configure the first terminal to use the third time period to detect the control channel; wherein the first signaling includes second indication information, which is used to indicate that the time period for the first terminal to wait to monitor the control channel is switched from the third time period to the first time period.

[0044] Other possible implementations and beneficial effects of the second aspect mentioned above can be found in the first aspect mentioned above, and will not be repeated here.

[0045] Thirdly, a communication method is provided. The method provided in the third aspect can be executed by a first terminal within a first cell.

[0046] For example, the method includes: receiving a first signaling signal for indicating a first time period, the first time period being a time period during which all terminals in the first cell wait to receive information on a control channel or a semi-persistent scheduling opportunity, and / or, the first time period being a time period during which all terminals in the first cell wait to send a scheduling request or information on a configuration grant channel; wherein the first signaling signal is a combination of one or more of the following: a first wake-up signal, or downlink control information.

[0047] Based on the above scheme, the first time period applies to terminal devices at the cell level. All terminals within the first cell (including the first terminal) can obtain the first time period through the first signaling, enabling them to perform operations such as waiting to receive and / or waiting to send within the first time period. These operations are not performed outside the first time period, thereby reducing the energy consumption of terminals and network devices within the first cell. Furthermore, the processing latency of the first signaling indicating the first time period is lower than that of RRC signaling. Compared to the current configuration of cell DRX / DTX via RRC, the first signaling can dynamically indicate the first time period, further reducing the energy consumption of terminals and network devices within the first cell while meeting actual service requirements. For example, in cases where data transmission becomes more concentrated, due to the lower processing complexity and latency of the first signaling, network devices can promptly instruct all terminals within the first cell to use a shorter first time period that matches actual service requirements, thereby further reducing the energy consumption of terminals and network devices within the first cell while meeting actual service requirements.

[0048] In some implementations, the first time period is the active period in a cell-level discontinuous transmission / discontinuous reception cycle; or, the first time period belongs to a first set, which includes time periods of the first cell that can be used to wait for information on the control channel or semi-persistent scheduling opportunity, and / or time periods that can be used to wait for information on the scheduling request or configuration grant channel. The multiple time periods in the first set are distributed non-interval in the time domain, or the multiple time periods in the first set are distributed aperiodically in the time domain, or two time periods in the multiple time periods of the first set have different lengths.

[0049] As an example, a non-spaced distribution can be understood as a continuous distribution.

[0050] Based on the above solution, the first time period can be adapted to the activation period of Cell DTX / DRX. Alternatively, the first time period can consist of multiple time periods that are continuously distributed, non-periodic, or irregular, thereby flexibly matching the needs of actual business operations.

[0051] In some implementations, the first signaling includes at least one of the following: indication information of the location of the first time period in the time domain; indication information of frequency domain resources used by the first terminal during the first time period; indication information of spatial domain parameters used by the first terminal during the first time period; or, indication information of power domain parameters used by the first terminal during the first time period.

[0052] Based on the above scheme, the first signaling can carry the above parameters, which can not only dynamically indicate the time period during which all terminals in the first cell wait to receive information on the control channel or the semi-persistent scheduling opportunity, and / or, the first time period is the time period during which all terminals in the first cell wait to send scheduling requests or configuration authorization channel information; but also indicate the frequency domain resources, spatial domain parameters or power parameters used in the above time period, so as to achieve flexible and unified indication.

[0053] In some implementations, the first signaling further includes: indication information of a first offset, wherein the first offset is the offset in the time domain between the time domain resource of the first signaling and the start position of the first time period.

[0054] The beneficial effects of the above implementation method can be found in the beneficial effects of the corresponding implementation method in the first aspect, and will not be repeated here.

[0055] In some implementations, the first signaling further includes: indication information for a second offset, wherein the second offset is the offset in the time domain between the end position of the first time period and the time domain resources of the second signaling, the time domain resources of the second signaling are located after the time domain resources of the first signaling, and the second signaling is used to indicate a fourth time period of waiting for the monitoring and control channel.

[0056] The beneficial effects of the above implementation method can be found in the beneficial effects of the corresponding implementation method in the first aspect, and will not be repeated here.

[0057] Fourthly, a communication method is provided. The method provided in the fourth aspect can be implemented by a network-side device.

[0058] For example, the method includes: sending a first signaling message to indicate a first time period, which is the time period during which all terminals in a first cell wait to receive information on a control channel or a semi-persistent scheduling opportunity, and / or, the first time period is the time period during which all terminals in a first cell wait to send information on a scheduling request or a configuration grant channel; wherein the first signaling message is a combination of one or more of the following: a first wake-up signal, or downlink control information.

For example, at least one of a, b, and c can mean: a, or, b, or, c, or, a and b, or, a and c, or, b and c, or, a, b, and c. Here, a, b, and c can each be single or multiple.

[0107] II. In this application, the terms "first," "second," and various numerical designations (e.g., #1, #2, etc.) indicate distinctions made for ease of description and are not intended to limit the scope of the embodiments of this application. For example, they may distinguish different messages, rather than describing a specific order or sequence. It should be understood that such descriptions can be interchanged where appropriate to describe solutions other than those in the embodiments of this application.

[0108] Third, in this application, descriptions such as "when," "under the circumstances," and "if" all refer to the device making corresponding processing under certain objective circumstances, and are not time-limited, nor do they require the device to make a judgment action when implementing it, nor do they imply any other limitations.

[0109] IV. In this application, "instruction" or "for instruction" can include both direct (or explicit) and indirect (or implicit) instruction. When describing instruction information as indicating A, it can include whether the instruction information directly or indirectly indicates A, but does not necessarily mean that the instruction information carries A. For example, in the case of indirect (or implicit) instruction, the receiving end of the instruction information can obtain A based on the parameters indicated by the instruction information, combined with other rules or parameters, or through deduction.

[0110] V. The indication methods involved in the embodiments of this application should be understood to cover various methods that enable the party to be indicated to obtain the information to be indicated. The information to be indicated can be sent as a whole or divided into multiple sub-information and sent separately.

For example, transmission can be uplink transmission, such as a terminal device sending a signal to a network device; transmission can also be downlink transmission, such as a network device sending a signal to a terminal device; transmission can also be sidelink transmission, such as a terminal device sending a signal to another terminal device. For example, "transmission" can be air interface level transmission, or it can be signal transmission from a chip input (I) / output (O) port, rather than air interface level transmission.

[0113] 8. In this application, terms such as “message”, “information”, “signal” or “information element (IE)” can be used interchangeably. There are no restrictions on the name of the message or information, as long as it can achieve the corresponding function.

"Receiving information from XX (device), or receiving information from XX (device)" can be understood as the source of the information being that device. This can include receiving information directly or indirectly from that device. Information may undergo necessary processing between the source and destination, such as format changes, but the destination can understand the valid information from the source. Similar expressions in this application can be understood in a similar way, and will not be repeated here. Furthermore, "sending" can also be understood as the "output" of the chip interface, and "receiving" can also be understood as the "input" of the chip interface. In other words, "sending" or "receiving" can occur between devices, for example, between network devices and terminal devices via an air interface.

For example, signaling configuration includes configuration using signaling sent by network devices, which can be radio resource control (RRC) messages, downlink control information (DCI) messages, or system information blocks (SIBs). Another example is signaling configuration between network devices. These network devices can include access network devices, core network devices, or management plane devices, etc. Optionally, signaling configuration can also be configured to terminal devices or network devices by pre-configured signaling, or configured to terminal devices or network devices through pre-configuration. Here, pre-configuration means defining or configuring the values ​​of corresponding parameters in advance using a protocol, and storing them in the terminal device or network device during communication.

[0121] Figure 1 This is a schematic diagram of a communication system 100. (For example...) Figure 1 As shown, the communication system 100 includes a wireless access network 110 and a core network 120. Optionally, the communication system 100 may also include an Internet 130. The wireless access network 110 may include at least one access network device (such as...). Figure 1111a and 111b in the above), may also include at least one terminal device (such as Figure 1 (112a-112j in the original text). The terminal device connects to the access network device wirelessly. The access network device connects to the core network 120 wirelessly or via a wired connection. The core network 120 may include one or more core network devices. The core network device and the access network device may be independent physical devices, or the functions of the core network device and the logical functions of the access network device may be integrated on the same physical device, or a single physical device may integrate some of the functions of the core network device and some of the functions of the access network device. Terminal devices and access network devices can be interconnected via wired or wireless means. Terminal devices can communicate wirelessly with each other, with each other, and with each other via air interface resources. For example, air interface resources may include at least one of time-domain resources, frequency-domain resources, code resources, and spatial resources. Figure 1 This is a schematic diagram. The communication system 100 may also include other access network equipment, such as wireless repeater equipment and wireless backhaul equipment. Figure 1 It is not shown in the middle.

[0122] Access network equipment can be any device with wireless transceiver capabilities. For example, access network equipment can be a base station used to connect terminal devices to a radio access network (RAN). Access network equipment is sometimes also referred to as an access network element, access network node, RAN node, or RAN. It is understood that the name of a device with access network equipment functionality may differ in systems employing different wireless access technologies. Exemplarily, access network equipment includes, but is not limited to, various forms of macro base stations (such as…). Figure 1 111a), super base station, micro base station or indoor station (such as Figure 1Access network equipment includes 111b), pico base stations, small stations, satellite stations, balloon stations, drone stations, relay stations, and access points. Access network equipment can include evolved node Bs (eNBs or eNodeBs) in LTE, access points (APs), wireless relay nodes, wireless backhaul nodes, transmission points (TRPs or TPs), or transmission reception points (TRPs) in Wi-Fi systems. It can also include next-generation NodeBs (gNBs) or transmission points (TRPs or TPs) in 5G systems, one or a group of antenna panels (including multiple antenna panels) of base stations in 5G systems, and network nodes constituting gNBs or transmission points, such as baseband units (BBUs) or distributed units (DUs). Furthermore, it can include access network equipment, servers, or vehicle-mounted equipment in networks evolving after 5G. Access network equipment can also be modules or units that perform some of the functions of a base station. For example, it can be a central unit (CU) or a DU.

[0123] In this embodiment, the apparatus for implementing the functions of the access network device can be the access network device itself, or it can be an apparatus capable of supporting the access network device in implementing the functions, such as a chip system, which can be installed in the access network device. The chip system can be composed of chips, or it can include chips and other discrete components.

[0124] In another possible scenario, multiple access network devices collaborate to assist the terminal in achieving wireless access, with each device performing a specific function. For example, the access network devices could be a CU, DU, CU (control plane, CP), CU (user plane, UP), or a radio unit (RU). The CU and DU can be separate entities or included in the same network element, such as a BBU. The RU can be included in radio equipment or radio units, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0125] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an open radio access network (O-RAN) system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules. The embodiments of this application do not limit the specific technology or specific device form used in the access network equipment.

[0126] Terminal equipment can be a device that provides voice and / or data connectivity to users. Terminal equipment can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; it can also be deployed on water (such as ships); and it can be deployed in the air (such as airplanes, balloons, and satellites). Terminal equipment can also be referred to as user equipment (UE), access terminal, terminal, subscriber unit, user station, mobile station, mobile station (MS), mobile terminal (MT), remote station, remote terminal, mobile device, user terminal, wireless network equipment, user agent, or user device. In this application embodiment, terminal devices include, but are not limited to: cellular phones, mobile phones, wireless data cards, wireless modems, tablets, laptop computers, notebook computers, handheld computers, mobile internet devices (MIDs), computers with wireless transceiver capabilities, cordless phones, session initiation protocol (SIP) phones, smartphones, wireless local loop (WLL) stations, personal digital assistants (PDAs), handsets with wireless communication capabilities, computing devices or other devices connected to wireless modems, in-vehicle devices (e.g., cars, bicycles, electric vehicles, airplanes, ships, trains, high-speed trains, etc.), wearable devices (e.g., smartwatches, smart bracelets, pedometers, smart glasses, etc.), satellite terminals, terminal devices in the Internet of Things or the Internet of Vehicles, as well as any form of terminal in future communication networks, relay user equipment, or terminals in future evolved public land mobile networks (PLMNs), etc.Terminal devices can also be virtual reality (VR) devices, augmented reality (AR) devices, smart point-of-sale (POS) machines, customer-premises equipment (CPE), light UE, reduced capability UE (REDCAP UE), machine-type communication (MTC) terminals, terminal devices in industrial control, terminal devices in self-driving, terminal devices in telemedicine, terminal devices in smart grids, wireless terminals in transportation safety, terminal devices in smart cities, terminal devices in smart homes, tactile terminal devices, smart home devices (e.g., refrigerators, televisions, air conditioners, electricity meters, etc.), smart robots, robotic arms, workshop equipment, wireless terminals in self-driving, or flying devices (e.g., smart robots, hot air balloons, drones, airplanes), etc. The terminal device can also be a vehicle device, such as a complete vehicle device, an in-vehicle module, an in-vehicle chip, an on-board unit (OBU), or a telematics box (T-BOX). The terminal device can also be other devices with terminal functions; for example, it can be a device that functions as a terminal in device-to-device (D2D) communication. This application does not limit the scope of the embodiments in this regard.

[0127] In this application embodiment, the device for implementing the functions of the terminal device can be the terminal device itself, or it can be any device capable of supporting the terminal device in implementing the functions, such as a chip or chip system. This device can be installed in the terminal device. The chip system can consist of chips or include chips and other discrete components. In the technical solution of this application embodiment, the device for implementing the functions of the terminal device is referred to as the terminal device, which can also be called a terminal. The following description may use a UE (User Equipment) as an example to illustrate the technical solution provided in this application embodiment.

[0128] The roles of access network devices and terminals can be relative, for example, Figure 1The helicopter or drone 112i in the diagram can be configured as a mobile access network device. For terminals 112j that access the wireless access network 110 via 112i, terminal 112i is an access network device; however, for access network device 111a, 112i is a terminal, meaning that 111a and 112i communicate via a wireless air interface protocol. Alternatively, 111a and 112i can also communicate via an interface protocol between access network devices; in this case, 112i is also an access network device relative to 111a. Therefore, both the base station and the terminal can be collectively referred to as communication devices. Figure 1 111a and 111b in the text can be referred to as communication devices with access network equipment functions. Figure 1 The 112a-112j in the text can be referred to as communication devices with terminal functions.

[0129] Furthermore, this application can be applied to standalone (SA) scenarios, dual connectivity (DC) scenarios, or other scenarios.

[0130] Access network devices and terminal devices can communicate via wireless links. The transmission link from the access network device to the terminal device can be called a downlink (DL) or downlink channel, used for transmitting downlink signals. The transmission link from the terminal device to the access network device can be called an uplink (UL) or uplink channel, used for transmitting uplink signals. The transmission link from one terminal device to another can be called a sidelink (SL) or sidelink channel, used for transmitting sidelink signals.

[0131] Figure 2 This is a schematic block diagram of a communication device 200 provided in an embodiment of this application. For example, the communication device 200 can be a terminal device or a network device.

[0132] For example, the communication device 200 may include a first module 210 and a second module 220.

[0133] As an example, the first module 210 can be used for data transmission with other communication devices. For instance, the first module 210 can be used to send and receive signaling or data, or to measure signals.

[0134] The first module 210 can also be called the main radio (MR) module, main receiver, main communication module, main circuit, high power circuit, or high power module, etc.

[0135] As examples, the second module 220 can be used to maintain connections with other communication devices, monitor information, transmit small packets, and turn the first module 210 on or off. For example, turning on the first module 210 can also be understood as waking up the first module 210, and turning off the first module 210 can also be understood as putting the first module 210 into hibernation.

[0136] As other examples, the second module 220 can also be used to receive or transmit low-power signals. The operating power consumption of the second module 220 can be lower than that of the first module 210. For example, from a functional perspective, the low-power signal may include a low-power wake-up signal (LP-WUS).

[0137] As an example, low-power signals may include at least one of the following: linear frequency modulated chirp signals, on-off keying (OOK) signals (such as OOK-1, OOK-2, OOK-3, OOK-4, etc.), low-power sequence signals (such as gold sequence signals, M sequence signals, ZC sequence signals, chirp sequence signals, Walsh sequence signals, Golay sequence signals, Kasami sequence signals, low-density sequence signals, discrete Fourier transform (DFT) / fast Fourier transform (FFT) sequence signals, quadrature amplitude modulation (QAM) signals, symbol-based sequence signals, etc.), amplitude shift keying (ASK) signals, frequency shift keying (FSK) signals, or orthogonal frequency division multiplexing (OFDM). Low-power signals may also include signals obtained by optimizing the specific signals mentioned above, and this application does not limit this.

[0138] Furthermore, the low-power signal can be a digital signal or an analog signal; this application does not limit this. The second module 220 can also be referred to as a power-on circuit, wake-up circuit, low-power circuit, wake-up receiver (WUR), communication auxiliary module, auxiliary circuit, low-power wake-up receiver (LP-WUR), or low-power radio (LP-R) module, etc. The aforementioned LP-R module can also be simply referred to as the LR module.

[0139] In some examples, if the communication device 200 (e.g., a terminal device or a network device) does not transmit low-power signals, the communication device 200 may also exclude the second module 220.

[0140] To facilitate understanding of the embodiments of this application, the following is a brief, exemplary description of the concepts that may be involved in the embodiments.

[0141] 1. Time unit:

[0142] Unless otherwise specified, the time unit (or time domain unit) in this application may include any of the following:

[0143] • Absolute units of time, such as milliseconds (ms), microseconds (us), or seconds (s).

[0144] • Symbol.

[0145] • Mini slot.

[0146] • Slot.

[0147] · Subframe.

[0148] • Frame.

[0149] Other time units.

[0150] As some examples of other time units, the time unit can also be "N". For example, "N" can be related to the subcarrier spacing.

[0151] As an example, the subcarrier spacing is 15*2 μ kilohertz (kHz), N can be 14*2 μ There are several symbols. μ can be a natural number. For example, μ = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, ... "*" can represent multiplication. For example, the subcarrier spacing is 15 * 2. 0 kHz, N can be 14 symbols; subcarrier spacing is 15*2 1 kHz, N can be 28 symbols; subcarrier spacing is 15*2 2 kHz, N can be 56 symbols. And so on.

[0152] For example, the time unit "N" described above can be applied to future communication systems. For instance, "N" could be the time unit for configuring network devices in a future communication system.

[0153] Unless otherwise specified, the "starting position in the time domain" and "ending position in the time domain" in this application can be understood as the first time unit occupied in the time domain and the last time unit occupied in the time domain, respectively. For example, the starting position of the first time period in the time domain can be understood as the first symbol or time slot occupied by the first time period in the time domain.

[0154] Furthermore, unless otherwise specified, the time domain length in this application can be the length of absolute time, or it can consist of one or more time units.

[0155] 2. DRX Mechanism:

[0156] As described in the background section, in actual communication services, terminal devices do not constantly interact with network devices to exchange effective information. To save energy (e.g., battery power) for terminal devices, some related solutions have proposed the DRX mechanism. Under the DRX mechanism, when a network device has service data to send to a terminal device, the terminal device can monitor the PDCCH; otherwise, the terminal device does not monitor the PDCCH, thereby saving energy consumption and extending the standby time of the terminal device.

[0157] As an example, network devices can configure DRX cycles for end devices. A DRX cycle can include an active period and a sleep period. End devices can monitor the PDCCH during the active period of the DRX cycle, but not during the sleep period.

[0158] The activation period in the aforementioned DRX cycle can also be called the DRX activation period, DRX wake-up period, or other names. For ease of understanding, it will be described below using the name DRX activation period.

[0159] The dormancy period in the aforementioned DRX cycle can also be called the inactive period, DRX inactive period, DRX dormancy period, or other names. For ease of understanding, it will be described below as the DRX dormancy period.

[0160] For example, the DRX of a terminal device may include a connected DRX (C-DRX) and an idle DRX (i-DRX).

[0161] As an example, the configuration parameters for a terminal device's DRX may include at least one of the following parameters:

[0162] 1) Period, for example, the configuration parameters of DRX can include two periods, such as long period and short period;

[0163] 2) The length of the activation period, also known as the "activation period" length or other names;

[0164] 3) Parameters in other DRX configurations (DRX-Config, DRX-ConfigExt-v1700, DRX-ConfigExt2-v1800).

[0165] Among them, DRX-Config, DRX-ConfigExt-v1700, or DRX-ConfigExt2-v1800 can be used to configure DRX-related parameters. As examples, DRX-Config, DRX-ConfigExt-v1700, or DRX-ConfigExt2-v1800 may include at least one of the following parameters: drx-HARQ-RTT-TimerDL, drx-HARQ-RTT-TimerUL, drx-Inactivity Timer, drx-LongCycleStartOffset, drx-NonIntegerLongCycleStartOffset, drx-NonIntegerShortCycle, drx-onDuration Timer, drx-Retransmission TimerDL, drx-Retransmission TimerUL, drx-ShortCycle Timer, drx-ShortCycle, drx-SlotOffset, drx-TimeReferenceSFN, shortDRX, etc. Descriptions of these parameters can be found in the corresponding sections of 3GPP standard protocol 38.331, and will not be detailed here.

[0166] To facilitate understanding, the following will be combined with Figure 3 An example of a DRX cycle is provided. Figure 3 As shown in (a), each DRX cycle includes a DRX activation period and a DRX sleep period. During the DRX activation period, the terminal device can monitor and receive the PDCCH, in other words, the terminal device can enter a wake-up state; during the inactive period, the terminal device can enter a sleep state, that is, it does not monitor or receive the PDCCH, thereby reducing power consumption.

[0167] In some possible implementations, the terminal device can start an onduration timer at the beginning of the DRX cycle, and the length of this timer can be... Figure 3(a) shows the length of the DRX activation period. This allows the terminal device to monitor and receive the PDCCH before the timer expires. After the timer expires, the terminal device can enter a sleep state, i.e., it does not monitor or receive the PDCCH, thus reducing power consumption. Before the activation period timer expires, other timers may be triggered, which can extend the DRX activation period, ultimately resulting in... Figure 3 (a) shows the length of the DRX activation period.

[0168] 3. Cell DTX and DRX:

[0169] Under the DTX and DRX mechanisms of a cell, network devices may not transmit and / or receive certain channels or signals during certain time periods within a cycle. The cell's DTX and DRX related parameters can be activated / deactivated by RRC signaling or DCI. The cell's DTX and DRX mechanisms can be configured and activated separately. When configuring the cell's DTX and DRX mechanisms, the activation time and cycle parameters of the DTX and DRX mechanisms can be shared.

[0170] For example, the configuration parameters of a cell's DTX and DRX may include at least one of the following parameters:

[0171] 1) cellDTXDRX-onDurationTimer, this parameter is used to configure the on duration period;

[0172] 2) cellDTXDRX-CycleStartOffset, this parameter is used to configure the cycle and starting offset, where the starting offset can be a subframe-level offset;

[0173] 3) cellDTXDRX-SlotOffse, this parameter is used to configure the slot offset;

[0174] 4) cellDTXDRXConfigType: This parameter describes the configuration type. The configuration type can be cell DTX, cell DRX, or cell DTX and cell DRX.

[0175] 5) cellDTXDRX-activationStatus, this parameter is used to configure the initial activation status.

[0176] These parameters can be found in the relevant section of 3GPP standard protocol 38.331, and will not be detailed here.

[0177] 4. WUS:

[0178] In some examples, the terminal device can monitor the WUS (Warranty Notice) to determine whether to monitor the PDCCH during the DRX activation period of the DRX cycle. For example, the WUS can be used to instruct the terminal device to monitor the PDCCH during the DRX activation period corresponding to the WUS. If the terminal device detects or receives the WUS at the WUS monitoring time, it can monitor the PDCCH during the DRX activation period corresponding to the WUS. If the terminal device does not detect or receive the WUS at the WUS monitoring time, it will not monitor the PDCCH during the DRX activation period corresponding to the WUS monitoring time.

[0179] As an example, the DRX activation period corresponding to WUS can be understood as either the first DRX activation period after the WUS, or the next DRX activation period after the WUS. Similarly, the DRX activation period corresponding to the monitoring timing of WUS can be understood as either the first DRX activation period after the monitoring timing of the WUS, or the next DRX activation period after the monitoring timing of the WUS.

[0180] WUS is used to indicate whether PDCCH is monitored during the DRX activation period. It can also be replaced by: WUS indicating or used to indicate whether the DRX activation period is started, wherein the terminal device can monitor PDCCH during the activation period.

[0181] Under the DRX mechanism, WUS is used to indicate whether PDCCH is monitored during the DRX activation period. It can also be replaced by WUS indicating whether to start the drx-onDuration Timer in the next DRX cycle. The terminal device can monitor PDCCH during the drx-onDuration Timer operation.

[0182] In the idle or inactive state, WUS is used to indicate whether PDCCH is monitored during the DRX active period. It can also be replaced by: WUS is used to indicate whether paging signals are monitored during the DRX active period, or WUS is used to indicate whether the paging occasion is monitored.

[0183] As an example, WUS in this application can also be replaced with LP-WUS, which will not be elaborated further.

[0184] In some examples, WUS in this application can be understood as one or more WUS included in a WUS occasion; or as one or more WUS transmitted or received on a WUS occasion. A WUS occasion may include monitoring occasions for one or more WUS. A terminal device can monitor WUS on a WUS monitoring occasion, or, as understood, receive WUS.

[0185] For example, a WUS can correspond to a time-domain parameter (such as the first time period ID, the third time period ID, the timer ID, K1 ID, or K2 ID, etc.). Another example is that a WUS can correspond to a frequency-domain parameter (such as indicating a carrier, a uni-carrier, a frequency band, etc.). Yet another example is that a WUS can correspond to a spatial-domain parameter (such as indicating a beam, a TRP, etc.). And yet another example is that a WUS can correspond to a power-domain parameter. After waking up the terminal device using a WUS, the terminal device can use the corresponding time-domain, frequency-domain, spatial, or power-domain parameters to monitor the PDCCH during the DRX activation period.

[0186] For the specific meanings of some of the terms mentioned above, please refer to the descriptions in information (1) to information (4) below.

[0187] In some examples, WUS timing can be UE-related. For instance, when the WUS is UE-level, the WUS timing includes one or more WUSs, with different WUSs corresponding to different UEs; that is, different WUSs are used to instruct different UEs to monitor the PDCCH. As another example, when the WUS is UE-group-level, the WUS timing includes one or more WUSs, with different WUSs corresponding to different UE groups; that is, different WUSs are used to instruct all UEs within different UE groups to monitor the PDCCH. Yet another example is when the WUS is cell-level, the WUS timing includes one or more WUSs, with different WUSs corresponding to different cells; that is, different WUSs are used to instruct all UEs within different cells to monitor the PDCCH. In these examples, the time-frequency resources of the different WUSs included in the WUS timing can be different.

[0188] In other examples, the WUS in this application may include multiple bits or fields. These multiple bits or fields may correspond to different time-domain parameters, frequency-domain parameters, spatial-domain parameters, power parameters, UEs, UE groups, or cells. A UE, a UE within a UE group, or a UE within a cell may use the frequency-domain parameters, spatial-domain parameters, or power parameters to monitor the PDCCH within the time period indicated by the time-domain parameters.

[0189] In some examples, network devices can send WUS to terminal devices with low latency through the physical layer as needed for business operations, thereby flexibly instructing terminal devices whether to monitor PDCCH.

[0190] In some possible implementations, the network device can configure the WUS monitoring timing for the terminal device. The WUS monitoring timing can be the monitoring timing when a specific UE receives a specific WUS within the WUS timing. For example, the network device can configure the WUS monitoring timing before the DRX activation period of each DRX cycle. The terminal device monitors the WUS before each DRX cycle. Only if the terminal device receives the WUS will it monitor the PDCCH during the DRX activation period of the corresponding DRX cycle; otherwise, if the terminal device does not monitor or receive the WUS, it indicates that the network device does not activate the terminal device to monitor the PDCCH during the DRX activation period of the current DRX cycle, and the terminal device can continue to maintain a sleep state, thereby further reducing power consumption.

[0191] by Figure 3 Taking the case shown in (b) as an example, Figure 3 (b) shows three DRX cycles, each of which can be configured with WUS monitoring timing (in...) Figure 3 (Used as small squares). Assume that before the first DRX cycle, the terminal device did not detect or receive WUS (in...). Figure 3 If hollow squares are used to represent this, the terminal device will remain in sleep mode during the first DRX cycle; assuming the terminal device receives WUS (in the second DRX cycle) before the second DRX cycle... Figure 3 (Using shaded squares to represent this), the terminal device monitors the PDCCH during the DRX activation period in the second DRX cycle (in...). Figure 3 (Using vertical shading to indicate); Assuming that the terminal device did not detect or receive WUS before the third DRX cycle (in Figure 3 If hollow squares are used to represent the terminal device, the terminal device will remain in sleep mode during the third DRX cycle.

[0192] Understandable Figure 3 This is a specific example provided for the purpose of understanding and is not intended to limit the scope of this application.

[0193] As mentioned earlier, the relevant solutions configure periodic activation and sleep periods for terminal devices via RRC signaling. Essentially, these solutions involve network devices semi-statically configuring terminal devices to periodically monitor the PDCCH. However, in actual service scenarios, the timing of data transmission may dynamically change, causing a mismatch between the data transmission timing and the activation period configured by the network device via RRC signaling. To match these dynamically changing service requirements, network devices may semi-statically configure longer activation periods for terminal devices. However, this results in higher power consumption for the terminal devices.

[0194] In view of this, this application proposes a communication method. In this communication method, the network device can carry dynamic parameters in signaling with a processing latency lower than that of RRC signaling (denoted as, first signaling). Exemplarily, the dynamic parameters can be used to modify the PDCCH monitoring time period configured in the RRC signaling, or to directly instruct the terminal device on the PDCCH monitoring time period. Therefore, this method can dynamically instruct the terminal device on the time period to wait for PDCCH monitoring, thereby helping to meet the needs of actual services and reducing the power consumption of the terminal device.

[0195] To facilitate understanding, the following will be combined with Figure 4 The communication method proposed in this application is described.

[0196] Figure 4 This is a schematic flowchart of a communication method 400 provided in an embodiment of this application. Optional operations in method 400 are shown with dashed lines. Some nodes involved in method 400 are described below.

[0197] First terminal. Unless otherwise specified, the first terminal in this application may be the terminal device itself, a component within the terminal device (e.g., a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the terminal device. For ease of description, the first terminal will be referred to as UE#1 below.

[0198] In some examples, the cell where UE#1 is located can be referred to as the first cell. The first cell may include one or more terminals. For ease of description, the terminals in the first cell will be referred to as UEs below.

[0199] Network-side equipment. Unless otherwise specified, the network-side equipment in this application can be the network device itself (e.g., access network equipment, core network equipment, or management plane equipment), a component within the network device (e.g., a processor, chip, or chip system), or a logical module or software capable of implementing all or part of the functions of the network device. For ease of understanding and description, the term "network-side equipment" will be used hereinafter to refer to it as "network device".

[0200] The following is combined with Figure 4 This section introduces the various operations of method 400.

[0201] S420, UE#1 receives the first signaling from the network device. As an example, the first signaling can be used to indicate a first time period. Correspondingly, the network device sends the first signaling to UE#1.

[0202] Based on the different meanings of the first time period, the examples are divided into two categories, namely UE-level examples and cell-level examples.

[0203] UE-level example:

[0204] In the UE-level example of method 400, the first time period can be the time period during which UE#1 monitors the control channel, or the time period during which UE#1 waits to receive the control channel after being woken up. The first time period can be a single time period, or multiple time periods distributed at intervals and / or continuously.

[0205] In some examples, the first signaling can be UE-level. For instance, a network device can send the first signaling only to UE#1, without sending it to other UEs. This example can also be understood as the first signaling being UE-specific.

[0206] In other examples, the first signaling can be at the UE group level. For example, the network device can send the first signaling to one or more UEs in a UE group, including (UE#1).

[0207] In some other examples, the first signaling can be at the cell level. For example, the network device can send the first signaling to all UEs (including UE#1) in one or more cells.

[0208] In a UE-level example, the first signaling can be a combination of one or more of the following: a first WUS, SIB, media access control (MAC) control element (CE), or a first DCI.

[0209] For example, the first signaling can be one or a combination of one or more of the following: first WUS, SIB, MAC CE, or first DCI.

[0210] When the first signaling is a multi-message message, it can include multiple parts of information, each carried in a different message. For example, the first signaling can be a combination of a first WUS and a first DCI. The first signaling can include two parts of information, one part carried in the first WUS and the other part carried in the first DCI.

[0211] The first signaling can be at the UE level, UE group level, or cell level. The following description uses the first signaling being the first WUS as an example.

[0212] In some examples, the first WUS can be UE-level. For instance, a network device can send the first WUS only to UE#1, without sending it to other UEs. This example can also be understood as the first WUS being UE-specific.

[0213] In other examples, the first WUS can be at the UE group level. For example, the network device can send the first WUS from one or more UEs in a UE group, including (UE#1).

[0214] In some other examples, the first WUS can be cell-level. For example, the network device can send the first WUS to all UEs (including UE#1) in one or more cells.

[0215] Examples of SIB, MAC CE, or the first DCI are as explained above and will not be repeated here.

[0216] As an example, the control channel in method 400 can be the PDCCH in a 5G communication system, or it can be the control channel in a future communication system after 5G. In a future communication system after 5G, the control channel monitored by UE#1 may still be called PDCCH, or it may have other names; this application does not limit this.

[0217] For ease of understanding, the following description will use the PDCCH control channel as an example.

[0218] As an example, UE#1 waiting to monitor PDCCH can be understood as UE#1 monitoring PDCCH, or UE#1 being able to monitor PDCCH, or UE#1 waiting to receive PDCCH after waking up, or UE#1 being able to receive PDCCH.

[0219] In idle or inactive state, UE#1 waits to monitor the PDCCH, which can be understood as UE#1 waiting to monitor the paging signal, or UE#1 monitoring the paging occasion. For example, UE#1 may wait to monitor the PDCCH of the paging signal, or UE#1 may monitor the PDCCH of the paging signal at the paging occasion.

[0220] In some possible implementations, after S420, method 400 also includes: S430.

[0221] S430, UE#1 waits to monitor PDCCH during the first time period.

[0222] As an example, S430 may include: UE#1 may, within a first time period, blindly detect DCI on PDCCH based on the control resource set and search space configured by the network device.

[0223] For example, the blind-detected DCI mentioned above may include a first DCI and / or a second DCI. For example, the first WUS may indicate some parameters of a first time period, and the first DCI may be used to indicate other parameters of the first time period. As an example, the second DCI may be used for new UL, DL, or SL transmissions for MAC entities. The function of the second DCI mentioned above can also be understood as part or all of the functions of the PDCCH monitored by UE#1.

[0224] It is understood that S430 only indicates that UE#1 can perform the operation of monitoring PDCCH within the first time period. This application does not limit whether UE#1 successfully monitors DCI on PDCCH. UE#1 does not monitor PDCCH outside the first time period (e.g., before or after the first time period).

[0225] Based on the above scheme, UE#1 can obtain the first time period through the first signaling, thereby enabling it to monitor the PDCCH within the first time period and not monitor the PDCCH outside the first time period, thus reducing the power consumption of UE#1. Furthermore, the first signaling indicating the first time period can be any one of the first WUS, SIB, MAC CE, or first DCI, or a combination of multiple of these. It is understood that the processing latency of the first WUS, SIB, MAC CE, and first DCI is lower than that of the RRC signaling. Therefore, through the first signaling, dynamic indication of the first time period can be achieved, which helps to further reduce the power consumption of UE#1 while meeting actual service requirements. For example, when data transmission becomes more centralized, due to the lower processing complexity and latency of the aforementioned first signaling, network devices can promptly instruct UE#1 to use a shorter first time period that matches actual service requirements, thereby further reducing the power consumption of UE#1 while meeting actual service requirements.

[0226] Community-level example:

[0227] In the cell-level example of method 400, the first time period may be the time period during which all UEs (including UE#1) in the first cell wait to receive information on the control channel or semi-persistent scheduling (SPS) timing; and / or, the first time period may be the time period during which all UEs (including UE#1) in the first cell wait to send information on the scheduling request (SR) or configured grant (CG) channel.

[0228] In a cell-level example, the first signaling can be cell-level. The network device can send the first signaling to all UEs within the first cell. It is understood that UE#1 can be one or more UEs within the first cell.

[0229] The first time period can be a single time period, or multiple time periods with an intermittent distribution and / or a continuous distribution.

[0230] In this application, some terms in the UE-level examples may have the same names as some terms in the cell-level examples. Unless otherwise specified, the terms in the UE-level examples are explained in detail in the UE-level examples, and the terms in the cell-level examples are explained in detail in the cell-level examples. For example, the meaning of the first time period in the UE-level examples is explained in detail in the UE-level examples; the meaning of the first time period in the cell-level examples is explained in detail in the cell-level examples. Where there are special instructions, the terms in the UE-level examples or the cell-level examples shall be understood in accordance with those special instructions.

[0231] In a cell-level example, the first signaling can be a combination of one or more of the following: a first WUS or a first DCI. For example, the first signaling can be the first WUS, or the first signaling can be the DCI. Another example is that the first signaling can be a combination of the first WUS and the first DCI. In the above examples, the first signaling can include two parts of information, one part of which is carried in the first WUS and the other part of which is carried in the first DCI.

[0232] In the cell-level example, the first WUS can be a cell-level WUS; the aforementioned first DCI can be a cell-level first DCI.

[0233] For a description of the control channel, please refer to the relevant description in the UE-level example. For ease of understanding, the following description uses the PDCCH as the control channel in the cell-level example.

[0234] As an example, the statement that all UEs in the first cell are waiting to receive the PDCCH can be understood as: all UEs in the first cell are monitoring the PDCCH; or, all UEs in the first cell are able to monitor the PDCCH; or, all UEs in the first cell are waiting to monitor the PDCCH; or, all UEs in the first cell are able to receive the PDCCH.

[0235] In some possible implementations, after S420, method 400 further includes: all UEs in the first cell waiting to receive PDCCH during a first time period.

[0236] It is understandable that all UEs in the first cell can perform the operation of waiting to receive PDCCH during the first time period. This application does not limit whether the above UEs have successfully detected DCI on PDCCH.

[0237] Taking UE#1 in the first cell as an example, UE#1 can execute the aforementioned S430. For details, please refer to the relevant description of S430, which will not be repeated here. Examples of other UEs in the first cell can be found in the example of UE#1, which will not be repeated here.

[0238] In some examples, the fact that all UEs in the first cell wait to receive SPS timing information during the first time period can be understood as: all UEs in the first cell wait to receive SPS PDSCH during the first time period; or, all UEs in the first cell wait to receive SPS timing during the first time period. In other words, the information during the SPS timing can be understood as the SPS PDSCH; and the aforementioned SPS timing can be understood as the timing used to receive the SPS PDSCH.

[0239] As an example, the fact that all UEs in the first cell are waiting to receive information on the SPS timing can be understood as meaning that all UEs in the first cell are able to receive information on the SPS timing.

[0240] It is understood that all UEs in the first cell can perform the operation of waiting to receive information on the SPS timing during the first time period. This application does not limit whether the above-mentioned UEs successfully receive information on the SPS timing.

[0241] In some examples, all UEs in the first cell wait to send SR during the first time period, which can be understood as: all UEs in the first cell are able to send SR.

[0242] It is understandable that all UEs in the first cell can perform the operation of waiting to send SR during the first time period. This application does not limit whether the above UEs successfully send SR.

[0243] In some examples, all UEs in the first cell wait to transmit information on the CG channel during the first time period. This can be understood as: all UEs in the first cell wait to transmit the CG channel during the first time period; or, all UEs in the first cell wait to transmit the CG channel during the first time period. As an example, the CG channel can be CG PUSCH.

[0244] As an example, the fact that all UEs in the first cell are waiting to send information on the CG channel can be understood as meaning that all UEs in the first cell are able to send information on the CG channel.

[0245] It is understood that all UEs in the first cell can perform the operation of waiting to send information on the CG channel during the first time period. This application does not limit whether the above UEs successfully send information on the CG channel.

[0246] For example, the first time period may be the time period during which all UEs (including UE#1) in the first cell wait to receive information on the PDCCH or SPS timing, and / or the first time period may be the time period during which all UEs (including UE#1) in the first cell wait to send information on the SR or CG channel. It can be understood that the first time period may be the time period during which all UEs in the first cell wait to receive information on the PDCCH or SPS timing, and / or the time period during which they send SR or CG.

[0247] In some possible implementations, all UEs in the first cell outside the first time period (e.g., before or after the first time period) may not wait to receive PDCCH, receive SPS timing information, send SR, or send CG channel information.

[0248] Based on the above scheme, all UEs (including UE#1) in the first cell can obtain the first time period through the first signaling, thereby enabling them to perform operations such as waiting to receive and / or waiting to transmit within the first time period, while not performing these operations outside the first time period. This reduces the energy consumption of UEs and network equipment in the first cell. Furthermore, the first signaling indicating the first time period can be any one of the first WUS or DCI, or a combination of the first WUS and DCI. It is understood that the processing latency of the first WUS and the first DCI is lower than that of the RRC signaling. Therefore, through the first signaling, dynamic indication of the first time period can be achieved, which helps to further reduce the energy consumption of UEs and network equipment in the first cell while meeting actual service requirements. For example, when data transmission becomes more concentrated, due to the lower processing complexity and latency of the aforementioned first signaling, network equipment can promptly instruct all UEs in the first cell to use a shorter first time period that matches actual service requirements, thereby further reducing the energy consumption of terminals and network equipment in the first cell while meeting actual service requirements.

[0249] The following section introduces some solutions that can be applied to both UE-level and cell-level examples.

[0250] In some possible implementations, prior to S420, method 400 further includes: the network device generating a first signaling. The first signaling can be used to indicate a first time period. This application does not limit the name of the first time period; for example, the first time period can be called a first data burst time period, a first monitoring time period, a first activation period, a first DRX activation period, a first wake-up time period, a first data burst, or other names.

[0251] In some examples, the timing (or time-frequency resource) of the first WUS monitoring in UE-level and cell-level examples can be configured by the network (NW) side.

[0252] As an example, NW-side configuration can be understood as: the network device is configured through at least one of RRC signaling, SIB, group-common DCI, or UE-specific DCI.

[0253] For example, the network device can send any one of the following signaling to UE#1: RRC signaling, SIB, group-common DCI, or UE-specific DCI. This signaling can be used to configure the monitoring timing of the first WUS.

[0254] For example, a network device can send a combination of multiple signaling messages to UE#1, including RRC signaling, SIB, group common DCI, or UE-specific DCI. Each signaling message in this combination can carry parameters for the monitoring timing of the first WUS, thereby configuring the monitoring timing of the first WUS. As a specific example, the SIB, group common DCI, or UE-specific DCI can carry some parameters for the monitoring timing of the first WUS, and the RRC signaling can carry another part of the parameters for the monitoring timing of the first WUS.

[0255] Optionally, the first signaling includes at least one of the following:

[0256] Information (1): Indication information of the location of the first time period in the time domain.

[0257] Information (2): Indication information of the frequency domain resources used by UE#1 during the first time period.

[0258] Information (3): Indication information of the spatial parameters used by UE#1 during the first time period.

[0259] Information (4): Indication information of the power domain parameters used by UE#1 during the first time period.

[0260] The numbering of information (1) to information (4) above is for ease of understanding and description only and is not intended to limit this application. An example of information (1) is given below.

[0261] For example, information (1) can be used to indicate the location of the first time period in the time domain.

[0262] In some examples, information (1) may carry at least one of the following: start position information, time domain length information, and end position information for the first time period. As an example, the start position information may be information indicating the start position; the time domain length information may be information indicating the time domain length; and the end position information may be information indicating the end position.

[0263] For example, information (1) may include the time domain length information and the start position information of the first time period. As another example, information (1) may include the time domain length information and the end position information of the first time period. Yet another example, information (1) may include the start position information and the end position information of the first time period.

[0264] In other examples, information (1) may include indication information for one or more timers, thereby indicating the position of the first time period in the time domain. That is, information (1) may indicate one or more timers. The aforementioned one or more timers may be equivalent to the first time period. In other words, the aforementioned first time period may be implemented by one or more timers.

[0265] For ease of description, the time period from timer start to timeout can be referred to as the timer's duration. As an example, the timer's indication information may include the timer's start position information and / or the timer's duration information. The aforementioned duration information can be understood as information indicating the duration.

[0266] In the example where information (1) indicates a timer, UE#1 may start the timer and perform the corresponding operation of UE#1 in the first time period described above before the timer terminates, i.e., as described in the UE-level example, UE#1 waits to monitor PDCCH in the first time period; or, as described in the cell-level example, UE#1 waits to receive information on the PDCCH or SPS timing, and / or, UE#1 waits to send information on the SR or CG channel.

[0267] The time-domain unit that starts the timer corresponds to the beginning position of the first time period in the time domain, and the time-domain unit that times out corresponds to the end position of the first time period in the time domain. In other words, the duration of the timer can be the aforementioned first time period.

[0268] In the example where information (1) indicates multiple timers, UE#1 can start multiple timers sequentially, or in other words, multiple timers can be triggered sequentially. The time domain unit started by the first timer among the multiple timers corresponds to the start position of the first time period in the time domain, and the time domain unit of the timeout of the last timer corresponds to the end position of the first time period in the time domain. In other words, the duration of the multiple timers can be the aforementioned first time period.

[0269] As an example, in any time domain unit between the timer that starts first and the time domain unit between the timer that expires last, at least one timer is running. Thus, the aforementioned first time period can be a single time period. As another example, in at least one time domain unit between the timer that starts first and the time domain unit between the timer that expires last, no timer is running. Thus, the aforementioned first time period can be multiple time periods distributed at intervals.

[0270] In the example where information (1) indicates multiple timers, information (1) may also include information indicating the dynamic relationship between the multiple timers.

[0271] For example, the dynamic relationship information of multiple timers can indicate that if certain conditions are met during the duration of timer #1 (or the first time period), timer #2 can be started. Timer #2 can be used to extend or terminate timer #1 (or the first time period) early.

[0272] In other examples, information (1) in the first signaling may indicate some parameters of the position of the first time period in the time domain. Before S420, i.e., before the network device sends the first signaling to UE#1, the network device may send RRC signaling to UE#1. This RRC signaling may include another part of the parameters of the position of the first time period in the time domain. For example, the RRC signaling may indicate the start position of the first time period, and information (1) may indicate the time domain length of the first time period.

[0273] For ease of understanding, the following example uses the first signaling as the first WUS, combined with... Figure 5 (a) in the first signaling section introduces some examples of information (1).

[0274] Figure 5 This is a schematic diagram of the first time period provided in the embodiments of this application. See also... Figure 5In example (a), the first signaling can be a first WUS. This first WUS can indicate any one of the first time periods #1 to #3. For example, the first WUS can carry information (1), which #1 can indicate the position of the first time period #1, or the first time period #2, or the first time period #3 in the time domain. Thus, the first WUS can carry information (1), thereby enabling flexible indication of the first time period. Therefore, information (1) can be understood as a time-domain dynamic parameter, or a time-domain parameter. Furthermore, the aforementioned first WUS can also be called a high-capacity WUS or other names.

[0275] Based on the above scheme, by carrying indication information indicating the location of the first time period in the time domain through the first signaling, the location of the first time period in the time domain can be flexibly indicated. For ease of understanding, two examples of information (1) are introduced below, denoted as Information (1) Example 1 and Information (1) Example 2, respectively.

[0276] Information (1) Example 1:

[0277] In some examples, the starting position information of the first time period, or information (1), or the first signaling may include: indication information of the first offset.

[0278] For example, the first offset may be the offset in the time domain between the time domain resource of the first signaling and the start position of the first time period.

[0279] As an example, the time-domain resource of the first signaling mentioned above can be the time-domain resource for UE#1 to receive the first signaling, or the time-domain resource for the network device to send the first signaling. In the above information (1) example 1, the first signaling can be a single signaling, for example, in the UE-level example, the first signaling can be one of the first WUS, SIB, MAC CE, or first DCI. As another example, in the cell-level example, the first signaling can be the first WUS or the first DCI.

[0280] Unless otherwise specified, the time-domain location of the time-domain resource of the first signaling in this application can be simply referred to as the time-domain location of the first signaling. Accordingly, the term "location" in the above description can be replaced with "starting location," "ending location," or "location where the first signaling is located."

[0281] To facilitate understanding, the following example uses the first signaling as the first WUS to introduce some examples of the first offset.

[0282] Example 1 of the first offset: The first offset can be the offset between the ending position of the first WUS in the time domain and the starting position of the first time period. For example, the ending position of the first WUS in the time domain can be the last symbol of the first WUS in the time domain.

[0283] For ease of description and reading, the number of time-domain units between the termination position of the first signaling in the time domain and the start position of the first time period will be denoted as K1. For example, the first offset can be K1, indicating that the start position of the first time period is the first time-domain unit after K1 time-domain units of the time-domain resource of the first signaling. Alternatively, the first offset can be K1+1, indicating that the start position of the first time period is the (K1+1)th time-domain unit thereafter.

[0284] In some examples, the first signaling can be the first WUS. For example, see [link to example]. Figure 5 In (b), it is assumed that the first WUS indicates the first time period #3 by carrying indication information of the first offset. As a specific example, the indication information of the first offset can indicate K1, that is, indicate that the time domain termination position of the first WUS and the first time period #3 can be separated by K1 time domain units.

[0285] Example 2 of the first offset: The first offset can be the offset between the starting position of the first WUS in the time domain and the starting position of the first time period. For example, the starting position of the first WUS in the time domain can be the first symbol of the time domain resource of the first WUS in the time domain.

[0286] Example 3 of the first offset: The first offset can be the offset between the time domain cell where the first WUS is located in the time domain and the starting position of the first time period. For example, the first WUS may occupy only one symbol in the time domain, and this symbol can be the time domain cell where the first WUS is located in the time domain. As another example, the first offset can be the time slot offset between the time slot where the first WUS is located in the time domain and the first time slot occupied by the first time period in the time domain. In the above examples, information (1) may also include the starting position of the first symbol of the first time period in the above "first time slot occupied by the first time period in the time domain".

[0287] Optionally, information (1), or the first signaling, may further include: time-domain length information of the first time period. For example, information (1) or the first signaling may include: indication information of the first offset mentioned above, and time-domain length information of the first time period.

[0288] Optionally, information (1), or the first signaling, may further include: end position information of the first time period. For example, information (1) or the first signaling may include: indication information of the first offset mentioned above, and end position information of the first time period.

[0289] Optionally, information (1), or the first signaling, further includes indication information for one or more timers. As an example, the indication information for a timer may include the duration information of the timer. Examples of indication information for one timer and examples of indication information for multiple timers are described below.

[0290] In one example of timer indication information, the timer indication information may include duration information. The start position of the timer can be determined by the aforementioned first offset indication information, similar to the example of determining the start position of the first time period, and will not be repeated here.

[0291] In the example of indication information for multiple timers, the starting position of the timer that starts first among the multiple timers can be determined by the indication information of the aforementioned first offset.

[0292] In some examples, the first signaling can be the first WUS. For example, see [link to example]. Figure 5 In (b), it is assumed that the first WUS indicates the first time period #3, and the time domain termination position of the first WUS and the timer start position can be spaced K1 time domain units apart.

[0293] As an example, the above K1 (or, instead, the first offset) may be related to the capabilities of the user (e.g., UE#1) and / or to jitter parameters.

[0294] For example, the capabilities of the aforementioned user can be related to the time it takes for the user to process signals (e.g., WUS). Taking UE#1 as an example, the longer UE#1 takes to process WUS, the larger K1 can be, thus reserving more time for UE#1 to process WUS; the shorter the time UE#1 takes to process WUS, the smaller K1 can be, thus enabling UE#1 to execute the corresponding operation in the first time period in a timely manner, ensuring timely data transmission, that is, reducing data transmission latency.

[0295] In some examples, a user (e.g., UE#1) can report its capabilities to the network device. The network device can configure K1 based on the user's capabilities, or in other words, determine and issue a first offset based on the user's capabilities. Users with different capabilities may receive different indications for the first offset. For example, the stronger the user's capabilities (e.g., shorter WUS processing time; shorter wake-up time for PDCCH monitoring), the smaller the K1 indicated by the first offset received by that user. Conversely, the weaker the user's capabilities (e.g., longer WUS processing time; longer wake-up time for PDCCH monitoring), the larger the K1 indicated by the first offset received by that user.

[0296] For example, the jitter parameter described above can describe the short-term, non-cumulative change in the effective instantaneous position of a signal relative to its ideal time position. Based on the jitter parameter, it can be determined whether data arrives at the receiving end (e.g., UE#1 or network device) on time. The network device can determine K1 (or, alternatively, a first offset) based on the jitter parameter. For example, if the network device determines that the service delay is severe based on the jitter parameter, it can determine a larger K1.

[0297] In the UE-level example, the relationship between user capability and K1 can also be understood as the time when WUS and the first PDCCH that the user (e.g., UE#1) can monitor can be related to the user's capability.

[0298] Based on the above scheme, the starting position of the first time period can be dynamically changed with the position of the first signaling by using the first offset, thereby flexibly matching the needs of actual business.

[0299] Information (1) Example 2:

[0300] In some possible implementations, prior to S420, the method 400 also includes S410.

[0301] S410, the network device sends the indication information of the second time period to UE#1; correspondingly, UE#1 receives the indication information of the second time period from the network device.

[0302] In the UE-level example, the second time period can be the time period during which UE#1 waits to monitor the PDCCH.

[0303] In a cell-level example, the second time period can be the time period during which all UEs (including UE#1) in the first cell wait to receive information on the PDCCH or SPS timing; and / or, the second time period can be the time period during which all UEs (including UE#1) in the first cell wait to send information on the SR or CG channel.

[0304] For example, the indication information for the second time period can be carried in RRC signaling, WUS, SIB, MAC CE, or DCI. This application does not limit the specific signaling carried by the indication information for the second time period. It is understood that this second time period is the time period configured by the network device for UE#1 before the first signaling.

[0305] In Message (1) Example 2, Message (1), or the first signaling, can be used to update the second time period to the first time period. For ease of description, several examples are introduced below, taking the first signaling to update the second time period to the first time period as an example, and are referred to as Second Time Period Update Examples 1 to 6 respectively.

[0306] Example 1 of the second time period update:

[0307] As an example, the first signaling can instruct the second time period to end early. It can be understood that the early end of the second time period is equivalent to the first signaling updating the second time period to a shorter first time period. This first time period can be understood as the time period obtained by the early end of the second time period.

[0308] For example, if the length of the second time period is 8 symbols, and the first signaling indicates that the end position of the second time period is advanced to the 6th symbol out of the aforementioned 8 symbols, this is equivalent to the first signaling updating the second time period with a length of 8 symbols to the first time period with a length of 6 symbols.

[0309] As an example, the first signaling could indicate the end position of the first time period (i.e., the updated time period) in the time domain. For instance, the first signaling could indicate the index of the last symbol of the first time period. As another example, the first signaling could indicate the offset between the end position of the first time period in the time domain and the end position of the second time period.

[0310] Example 2 of the second time period update:

[0311] As an example, the first signaling can instruct the second time period to end later. It can be understood that delaying the end of the second time period is equivalent to the first signaling updating the second time period to a longer first time period. This first time period can be understood as the time period resulting from the delayed end of the second time period.

[0312] For example, if the length of the second time period is 8 symbols, and the first signaling indicates that the end position of the second time period is postponed to the second symbol after the above 8 symbols, it can be equivalent to the first signaling updating the second time period with a length of 8 symbols to a first time period with a length of 10 symbols.

[0313] As an example, the first signaling could indicate the end position of the first time period (i.e., the updated time period) in the time domain. For instance, the first signaling could indicate the index of the last symbol of the first time period. As another example, the first signaling could indicate the offset between the end position of the first time period in the time domain and the end position of the second time period.

[0314] Example 3 of the second time period update:

[0315] As an example, the first signaling can instruct the second time period to start with a delay. It can be understood that a delayed start to the second time period is equivalent to the first signaling updating the second time period to a shorter first time period. This first time period can be understood as the time period resulting from the delayed start of the second time period.

[0316] For example, if the length of the second time period is 8 symbols, and the first signaling indicates that the start position of the second time period is delayed to the second symbol of the aforementioned 8 symbols, this is equivalent to the first signaling updating the second time period with a length of 8 symbols to the first time period with a length of 7 symbols.

[0317] As an example, the first signaling could indicate the starting position of the first time period (i.e., the updated time period) in the time domain. For instance, the first signaling could indicate the index of the first symbol of the first time period. As another example, the first signaling could indicate the offset between the starting position of the first time period and the starting position of the second time period in the time domain.

[0318] Example 4 of the second time period update:

[0319] As an example, the first signaling can instruct the second time period to start earlier. It can be understood that the earlier start of the second time period is equivalent to the first signaling updating the second time period to a longer first time period. This first time period can be understood as the time period obtained by starting the second time period earlier.

[0320] For example, if the length of the second time period is 8 symbols, and the first signaling indicates that the start position of the second time period is advanced to the second symbol before the aforementioned 8 symbols, this is equivalent to the first signaling updating the second time period with a length of 8 symbols to the first time period with a length of 10 symbols.

[0321] As an example, the first signaling could indicate the starting position of a first time period (i.e., the updated time period) in the time domain. For instance, the first signaling could indicate the index of the first symbol of the first time period. As another example, the first signaling could indicate the offset between the starting position of the first time period in the time domain and the starting position of the second time period. As yet another example, the first signaling could indicate the offset between the starting position of the first time period in the time domain and the position of the first signaling in the time domain (i.e., the first offset).

[0322] Example 5 of the second time period update:

[0323] As an example, the first signaling can instruct the skipping of one or more sub-time periods within the second time period. It can be understood that skipping one or more sub-time periods within the second time period is equivalent to the first signaling updating the second time period to the first time period. The first time period can be understood as a set of multiple intermittently distributed sub-time periods after skipping one or more sub-time periods of the second time period.

[0324] The second time period can include multiple sub-time periods. Skipping one sub-time period of the second time period can be understood as UE#1 not performing the corresponding operation in the UE-level example or the corresponding operation in the cell-level example during that sub-time period, thereby helping to reduce the energy consumption of UE#1.

[0325] As a specific example, the second time period can include 7 sub-time periods, and some of the 7 sub-time periods can be skipped.

[0326] For example, a sub-time period can be one or more symbols, one or more time slots, one or more subframes, one or more frames, one or more milliseconds, one or more seconds, or one or more other time units.

[0327] Taking a sub-time period as an example, we will introduce one possible implementation of the first signaling.

[0328] In some examples, the first signaling may include a bitmap. Assuming the second time period consists of 7 time slots, this bitmap may include 7 bits. These 7 bits can correspond one-to-one with the 7 time slots. For example, a bit value of "0" can indicate skipping the time slot corresponding to that bit, and a bit value of "1" can indicate not skipping the time slot corresponding to that bit.

[0329] As an example, the bitmap above, "1110001", can represent skipping the 4th to 6th time slots in the second time period. As another example, the bitmap above, "1100100", can represent skipping the 3rd, 4th, 6th, and 7th time slots in the second time period.

[0330] The relationship between the values ​​of the bits mentioned above and whether to skip is illustrative. For example, a bit value of "1" can also indicate skipping, and a bit value of "0" can also indicate not skipping.

[0331] In other examples, the first signaling may include indication information for one or more sub-time periods. As an example, the aforementioned one or more sub-time periods may be one or more sub-time periods that have been skipped in the second time period, or one or more sub-time periods in the first time period (or, in other words, one or more sub-time periods remaining in the second time period).

[0332] For example, the indication information for a sub-time period may include the starting position information of the sub-time period in the time domain, as well as the length information of the sub-time period.

[0333] For example, the indication information for multiple sub-time periods can each include the start position information of each sub-time period in the time domain, and the length information of each sub-time period. As another example, the indication information for the first sub-time period in the time domain can include its start position information and its length information. The indication information for a sub-time period that is not the first in the time domain can include the interval information between it and the previous sub-time period. The indication information for the last sub-time period in the time domain can include the interval information between it and the previous sub-time period, and its length information.

[0334] The following is an example of information (2).

[0335] For example, information (2) can be used to indicate the frequency domain resources used by UE#1 during the first time period. For instance, in a UE-level example, information (2) can be used to indicate the frequency domain resources used by UE#1 while waiting to monitor the PDCCH during the first time period. As another example, in a cell-level example, information (2) can be used to indicate the frequency domain resources used by all UEs in the first cell while waiting to receive information on the PDCCH or SPS timing during the first time period, and / or the frequency domain resources used by all UEs in the first cell while waiting to transmit information on the SR or CG channel during the first time period.

[0336] As an example, a frequency domain resource can be any of the following: carrier, carrier group, band, band group, cell, bandwidth part (BWP), BWP group, uni-carrier (or single-carrier), or uni-carrier group. For example, multiple carriers can come from the same cell (or the same uni-carrier). As another example, multiple carriers can come from multiple cells (or multiple uni-carriers), which is not limited in this application. Several examples of information (2) are described below, referred to as examples 1 to 3 of information (2).

[0337] Information (2) Example 1:

[0338] As an example, information (2) may indicate the number of one or more frequency domain resources corresponding to the first time period. In this way, UE#1 may use one or more frequency domain resources corresponding to the number during the first time period to perform the corresponding operation in the UE-level example or the corresponding operation in the cell-level example.

[0339] Information (2) Example 2:

[0340] As an example, information (2) can activate and / or deactivate one or more frequency domain resources. UE#1 can use the activated frequency domain resources to perform the corresponding operation in the UE-level example or the corresponding operation in the cell-level example. UE#1 does not use the deactivated frequency domain resources to perform the corresponding operation in the UE-level example or the corresponding operation in the cell-level example. Information (2) can perform one of the activation and deactivation operations, or it can perform both activation and deactivation simultaneously. For example, information (2) can activate frequency domain resources #1 to #3 while deactivating frequency domain resources #4 to #6. The activated or deactivated frequency domain resources can be predefined, pre-configured, configured by the network device before S420, or otherwise acquired by UE#1.

[0341] Further, optionally, information (2) is also used to indicate the addition of one or more frequency domain resources. For example, information (2) can instruct UE#1 to add frequency domain resources #4 to #6 while activating frequency domain resources #1 to #3. In this way, UE#1 can use frequency domain resources #1 to #6.

[0342] Further, optionally, information (2) may also be used to instruct the reduction of one or more frequency domain resources. For example, information (2) may instruct UE#1 to reduce frequency domain resources #4 to #6 while deactivating frequency domain resources #1 to #3. The frequency domain resources that are "deactivated" may be activated later and thus reused by UE#1. The frequency domain resources that are "reduced" cannot be activated.

[0343] As a concrete example, the information (2) used to activate and / or deactivate one or more frequency domain resources can be implemented using a bitmap. For example, before S420, the network device can configure frequency domain resources #1 to #6 for UE#1, and the information (2) can be 6 bits, corresponding one-to-one with frequency domain resources #1 to #6. Exemplarily, a bit value of "0" can indicate deactivation of the frequency domain resource corresponding to that bit, and a bit value of "1" can indicate activation of the frequency domain resource corresponding to that bit. Alternatively, a bit value of "1" indicates deactivation, and a bit value of "0" indicates activation.

[0344] In some related schemes, WUS can activate the UE to monitor the PDCCH on one carrier within a certain time period. The network device then instructs the activation of other carriers via RRC signaling or MAC CE, so that the UE can monitor the PDCCH on other carriers within the aforementioned time period. The above-mentioned related schemes require two steps to activate multiple carriers, resulting in a large delay. However, based on the information (2) example 1 and information (2) example 2 provided in the embodiments of this application, multiple carriers can be instructed or activated at once through information (2) in the first signaling, and the delay of monitoring the PDCCH on multiple carriers is small; it can also reduce the power consumption of UE#1 receiving signals.

[0345] Information (2) Example 3:

[0346] As an example, information (2) can switch one frequency domain resource to another. UE#1 can use the switched frequency domain resource to perform the corresponding operation in the UE-level example, or perform the corresponding operation in the cell-level example. UE#1 does not use the original frequency domain resource to perform the corresponding operation in the UE-level example, or perform the corresponding operation in the cell-level example.

[0347] For example, information (2) can switch frequency domain resource #1 to frequency domain resource #2, and UE #1 can use frequency domain resource #2 to perform the corresponding operation in the UE-level example or the corresponding operation in the cell-level example within the first time period.

[0348] The frequency domain resources before and after the handover can be predefined, preconfigured, configured by the network device before S420, or obtained by UE#1 through other means.

[0349] As a concrete example, the information (2) used for handover can be implemented using 1 bit. For example, a value of "0" for this bit can indicate that the frequency domain resource currently used by UE#1 by default should be switched to another frequency domain resource; a value of "1" for this bit can indicate that UE#1 should still use the currently used frequency domain resource by default. In short, a value of "0" for this bit can indicate "handover", and a value of "1" for this bit can indicate "no handover". Alternatively, a value of "1" for this bit can indicate "handover", and a value of "0" for this bit can indicate "no handover".

[0350] For example, in information (2) Example 3, the two frequency domain resources involved in the handover can be two BWP groups. The baseband parameters and / or radio frequency parameters of the different BWP groups can be different.

[0351] In other examples, the network device can configure frequency domain resources for M1 PDCCHs. Information (2) can indicate M2 frequency domain resources out of the M1 frequency domain resources. M2 is a positive integer less than or equal to M1. In this way, UE#1 can narrow down the range of time-frequency resources for blind detection DCI based on the time-frequency resources of the PDCCHs indicated by information (2), thereby reducing blind detection overhead, reducing blind detection complexity, and reducing UE#1's power consumption.

[0352] As an example, since information (2) is carried in dynamic first signaling, information (2) can be understood as a frequency domain dynamic parameter, or frequency domain parameter.

[0353] The following is an example of information (3).

[0354] For example, information (3) can be used to indicate the spatial parameters used by UE#1 during the first time period. For instance, in a UE-level example, information (3) can be used to indicate the spatial parameters used by UE#1 while waiting to monitor the PDCCH during the first time period. As another example, in a cell-level example, information (3) can be used to indicate the spatial parameters used by all UEs in the first cell while waiting to receive information on the PDCCH or SPS timing during the first time period, and / or the spatial parameters used by all UEs in the first cell while waiting to transmit information on the SR or CG channel during the first time period.

[0355] As an example, a spatial parameter can indicate any of the following: transmit (Tx) antenna, receive (Rx) antenna, Tx radio frequency, Rx radio frequency, Tx channel, Rx channel, transmit beam, receive beam, transmission reception point (TRP), or TRP group.

[0356] As an example, information (3) may indicate the number of one or more sets of spatial parameters. A set of spatial parameters may include one or more spatial parameters. For example, a set of spatial parameters may indicate the transmitting antenna and the receiving antenna. The values ​​of the specific spatial parameters in different sets of spatial parameters may be different. Other information regarding the numbering is similar to that in information (2) example 1, and will not be repeated here.

[0357] As an example, information (3) can activate, deactivate, add or remove one or more sets of spatial parameters, which is similar to information (2) example 2, and will not be repeated here.

[0358] As an example, information (3) can switch one set of spatial parameters to another set of spatial parameters, which is similar to information (2) Example 3, and will not be repeated here.

[0359] For example, since the information (3) is carried in the dynamic first signaling, the information (3) can be understood as a kind of spatial dynamic parameter, or spatial parameter.

[0360] The following is an example of information (4).

[0361] For example, information (4) can be used to indicate the power domain parameters used by UE#1 during the first time period. For instance, in a UE-level example, information (4) can be used to indicate the power domain parameters used by UE#1 while waiting to monitor the PDCCH during the first time period. As another example, in a cell-level example, information (4) can be used to indicate the power domain parameters used by all UEs in the first cell while waiting to receive information on the PDCCH or SPS timing during the first time period, and / or the power domain parameters used by all UEs in the first cell while waiting to transmit information on the SR or CG channel during the first time period.

[0362] As an example, a power domain parameter may include either transmit power or receive power.

[0363] As an example, information (4) may indicate the number of one or more sets of power domain parameters. A set of power domain parameters may include one or more power domain parameters. For example, a set of power domain parameters may include transmit power and receive power. The values ​​of the specific power domain parameters in different sets of power domain parameters may be different. Other information regarding the numbering is similar to that in information (2) example 1, and will not be repeated here.

[0364] As an example, information (4) can activate, deactivate, add or remove one or more sets of power domain parameters, which is similar to information (2) in Example 2, and will not be repeated here.

[0365] As an example, information (4) can switch one set of power domain parameters to another set of power domain parameters, which is similar to information (2) Example 3, and will not be repeated here.

[0366] For example, since the information (4) is carried in the dynamic first signaling, the information (4) can be understood as a power domain dynamic parameter, or a power domain parameter.

[0367] In some examples, the first signaling and RRC signaling can jointly indicate the parameters corresponding to the first time period. For example, the RRC signaling can indicate the location of WUS in the time domain and the location of the first time period in the time domain, i.e., information (1). The first signaling can be an SIB, which can indicate the frequency domain resources corresponding to the first time period, i.e., information (2). In this way, UE#1 can obtain the location of WUS and the first time period in the time domain based on the RRC signaling, and determine the frequency domain resources used by UE#1 in the first time period based on the first signaling (e.g., SIB). When UE#1 detects WUS, UE#1 can use the above-mentioned frequency domain resources to perform the corresponding operations in the UE-level example and the corresponding operations in the cell-level example in the first time period.

[0368] Optionally, the WUS configured in the above RRC signaling is the first WUS in this application. That is, in the above example, the first signaling can be a combination of the first WUS and SIB. As an example, the first WUS can carry information (3) and information (4), so that UE#1 can use the spatial domain parameters indicated by information (3) and the power domain parameters indicated by information (4) to perform the corresponding operation in the UE-level example and the corresponding operation in the cell-level example within the first time period.

[0369] Based on the above scheme, the first signaling can carry the aforementioned parameters, dynamically indicating not only the time-domain parameters of the first time period, but also the frequency-domain, spatial-domain, or power-domain parameters corresponding to the first time period, achieving flexible and unified indication. For example, the first signaling can be a combination of multiple signaling signals. Alternatively, the first signaling can be one of the first WUS, SIB, MAC CE, or first DCI signaling. This first signaling can uniformly indicate time-domain parameters, frequency-domain resources, spatial-domain parameters, or power parameters, etc. Compared to the scheme of using multiple signaling signals to indicate the above content separately, this scheme can reduce the power consumption of UE#1 receiving signals.

[0370] The above examples illustrate the information (1) to (4) that the first signaling may carry. The following section introduces other functional examples of the first signaling.

[0371] In some examples, the first signaling also includes indication information for the second offset.

[0372] As an example, the second offset could be the time-domain offset between the end position of the first time period and the time-domain resource of the second signaling.

[0373] For example, the second signaling can be used to indicate a fourth time period. This fourth time period can be located after the first time period. Similar to the behavior of UE#1 during the first time period, UE#1 can perform the corresponding operation of the UE-level example or the corresponding operation of the cell-level example during the fourth time period, which will not be elaborated further.

[0374] The second signaling may differ from the first signaling. For example, the time domain resources of the second signaling may be located after the time domain resources of the first signaling. That is, UE#1 may receive the second signaling after receiving the first signaling; the network device may send the second signaling after sending the first signaling.

[0375] For example, the time-domain resources of the aforementioned second signaling can be the time-domain resources for UE#1 to receive the second signaling, or the time-domain resources for the network device to send the second signaling. In the above example, the second signaling can be a single signaling signal; for example, in the UE-level example, the second signaling can be one of WUS, SIB, MAC CE, or DCI. As another example, in the cell-level example, the second signaling can be WUS or DCI.

[0376] Unless otherwise specified, the time-domain location of the second signaling resource in this application can be simply referred to as the time-domain location of the second signaling. Accordingly, the term "location" in the above description can be replaced with "starting location".

[0377] For ease of description and reading, the number of time-domain units between the end position of the first time period and the start position of the second signaling in the time domain is denoted as K2. Taking the calculation of the second offset starting from the end position of the first time period as an example, two specific examples of the second offset are introduced below.

[0378] For example, the second offset can be K2, representing the first time-domain unit after K2 time-domain units following the end position of the first time period. Alternatively, the second offset can be K2+1, representing the (K2+1)th time-domain unit after the first time period.

[0379] In some examples, the first signaling can be the first WUS, and the second signaling can be another WUS (denoted as WUS#1). For example, see Figure 5 In (b), it is assumed that the first WUS indicates the start position of WUS#1 in the time domain by carrying indication information of the second offset. As a specific example, the indication information of the second offset can indicate K2, that is, indicate that there can be an interval of K2 time domain units between the end position of the first time period #3 and the start position of WUS#1 in the time domain.

[0380] In some examples, the second signaling and the first signaling can be two adjacent signals in a periodically distributed set of signals. In other words, the second signaling can be the next signaling after the first signaling. As a specific example, both the second and first signaling can be WUS. For example, see [link to relevant documentation]. Figure 5 In (b), the first signaling can be the first WUS, and the second signaling can be WUS#1. Among them, WUS#1 can be the next WUS after the first WUS.

[0381] For example, UE#1 receiving the second signaling on the time domain resources of the second signaling can be understood as UE#1 monitoring the second signaling on the time domain resources of the second signaling. Thus, the time domain resources of the second signaling can also be referred to as the monitoring location of the second signaling.

[0382] Based on the above scheme, the monitoring position of the second signaling can be dynamically changed with the end position of the first time period by using the second offset, thereby flexibly matching the needs of actual business.

[0383] In other examples, the second offset can be the time-domain offset between the start position of the first time period and the time-domain resource of the second signaling. Specific examples are explained above and will not be repeated here.

[0384] The example of the second offset was given above. Below are some examples of how the various parameters are indicated.

[0385] In some examples, any of the aforementioned information (1) to information (4), or the indication information of the second offset, may carry specific parameters. For example, information (1) may carry K1 and the length information of the first time period.

[0386] In other examples, any of the aforementioned information (1) to information (4), or the indication information of the second offset, can carry an identifier (ID) corresponding to the specific parameter, thereby saving the transmission overhead of the first signaling. The following uses the example of the first signaling being the first WUS to introduce two examples, denoted as ID Example 1 and ID Example 2, respectively.

[0387] ID Example 1:

[0388] The first WUS can indicate an ID, which can correspond to K1 and the length of the first time period.

[0389] As an example, Table 1 shows a possible correspondence between ID, K1 and the length of the first time period.

[0390] Table 1

[0391] ID K1 Length of the first time period 00 - - 01 2 1 10 4 4 11 5 8

[0392] Referring to Table 1, the ID can be a binary number. For example, the ID "00" corresponds to K1 and the length of the first time period being empty (represented as "-" in Table 1). Thus, after receiving the first signaling, if the ID in that first signaling is "00", UE#1 can either maintain or enter a sleep state. That is, UE#1 may not perform the corresponding operation in the UE-level example or the corresponding operation in the cell-level example.

[0393] As an example, the unit of K1 in Table 1 can be a symbol or other time unit. The unit of length of the first time interval can be milliseconds, time slots, or other time units.

[0394] For example, K1 corresponding to ID "01" consists of 2 symbols, and the length of the first time period is 1 millisecond.

[0395] The columns and rows in Table 1 can be added, deleted, or modified, and the cells can also be added, deleted, or modified. The IDs in Table 1 can also correspond to other parameters, which is not limited in this application.

[0396] As an example, Table 2 shows another possible correspondence between ID, K1 and the length of the first time period.

[0397] Table 1

[0398] ID K1 Length of the first time period 00 2 1 01 4 4 10 5 8 11 8 10

[0399] Referring to Table 2, the ID can be a binary number. As an example, the unit of K1 in Table 2 can be a symbol or other time unit. The length of the first time segment can be in milliseconds, time slots, or other time units.

[0400] For example, K1 corresponding to ID "00" consists of 2 symbols, and the length of the first time period is 1 millisecond.

[0401] The columns and rows in Table 2 can be added, deleted, or modified, and the cells can also be added, deleted, or modified. The IDs in Table 2 can also correspond to other parameters, which is not limited in this application.

[0402] ID Example 2:

[0403] The first WUS can indicate two IDs, corresponding to K1 and the length of the first time period, respectively.

[0404] As an example, Table 3 shows one possible correspondence between ID and K1.

[0405] Table 3

[0406] ID K1 00 2 01 4 10 5 11 8

[0407] As an example, Table 4 shows a possible correspondence between IDs and the length of the first time period.

[0408] Table 4

[0409] ID Length of the first time period 00 1 01 4 10 8 11 10

[0410] Referring to Tables 3 and 4, the ID can be a binary number. As an example, the unit of K1 in Table 3 can be a symbol or other time unit. The unit of the length of the first time period in Table 4 can be milliseconds, time slots, or other time units.

[0411] For example, the first signaling can carry two IDs: the first ID is "00", indicating that K1 has 2 symbols, and the second ID is "01", indicating that the length of the first time period is 4 milliseconds.

[0412] The columns and rows in Table 3 or Table 4 can be added, deleted, or modified, and the individual cells can also be added, deleted, or modified. The IDs in Table 3 and Table 4 can also correspond to other parameters, which is not limited in this application.

[0413] Furthermore, in this application, ID, index, or number can be interchanged.

[0414] In some examples, the "length of the first time period" in ID Example 1 and ID Example 2 can be implemented using a timer. For example, timers with different durations or trigger conditions can correspond to different IDs.

[0415] The following section provides a further example of the first WUS.

[0416] In some examples, the first WUS can be a high-capacity WUS. For example, the first WUS can carry specific parameters of any of the aforementioned information (1) to information (4), or the indication information of the second offset. As another example, the number of bits in the first WUS is greater than or equal to (or, alternatively, greater than) 8 or 16.

[0417] In other examples, the first WUS may be an LP-WUS. For example, the first WUS may carry the ID corresponding to the specific parameter of any of the aforementioned information (1) to information (4), or the indication information of the second offset. As another example, the number of bits in the first WUS is less than or equal to (or, alternatively, less than) 8 or 16.

[0418] The following section introduces some solutions applicable to UE-level examples.

[0419] In some examples, UE#1 can adjust the first time period via a first timer after receiving the first signaling. In other examples, the first time period can be configured by the network device via RRC signaling, and UE#1 can adjust the first time period via a first timer.

[0420] In some possible implementations, method 500 further includes: if a first condition is met within a first time period, UE#1 starts the first timer. UE#1 may perform the corresponding operation in the UE-level example before the first timer expires, i.e., wait to monitor the PDCCH.

[0421] Optionally, the first timer is used to determine (or adjust to, or extend to) the end position of the first time period as the end position of the first timer. In some possible implementations, method 500 further includes: UE#1 determining (or adjusting to, or extending to) the end position of the first time period based on the first timer. For example, see Figure 5 In (c), UE#1 can monitor PDCCH during the duration of the first timer, which is equivalent to extending the first time period.

[0422] As an example, the first timer can be understood as the last timer triggered (or started) by UE#1 within the first time period. Before the first timer is triggered, there may be at least one timer triggered, or there may be no other timers triggered; this application does not limit this.

[0423] In some examples, the first signaling may also include indication information for a first timer. In other words, the first timer may be indicated by the first signaling.

[0424] Based on the above scheme, UE#1 can trigger the first timer under certain conditions. UE#1 can wait to monitor the PDCCH before the first timer expires. Therefore, the first timer can be used to extend the first time period. This mechanism allows UE#1 to adjust the PDCCH monitoring period itself, thereby helping to meet the needs of actual services. As an example, the first time period can also be implemented through one or more timers.

[0425] In other examples, UE#1 may receive a WUS (denoted as WUS#2) within a first time period. This WUS#2 includes indication information for a first timer; in other words, WUS#2 can be used to indicate the first timer. For example, WUS#2 may indicate the start position and duration of the first timer in the time domain. Another example is that WUS#2 may indicate the offset between the first timer and the time domain resources of WUS#2, as well as the duration of the second timer. Yet another example is that WUS#2 may indicate the duration of the first timer, where the start position of the first timer in the time domain defaults to the position of the time domain resources of WUS#2 in the time domain. As an example, the start position of the first timer in the time domain may default to the first time domain unit after the end position of the time domain resources of WUS#2 in the time domain.

[0426] The aforementioned WUS#2 can be the first WUS. As an example, the network device configures a first time period via RRC signaling. UE#1 can receive the first signaling, which is the first WUS, and this first WUS can be WUS#2 in the example above. This WUS#2 can include indication information for the first timer, thereby enabling dynamic indication of the first timer.

[0427] The aforementioned WUS#2 can also be another WUS besides the first WUS. As an example, the network device dynamically indicates a first time period through the first WUS. UE#1 can receive another WUS, namely WUS#2, during the first time period. This WUS#2 can include indication information of the first timer, thereby realizing dynamic indication of the first timer.

[0428] For example, the first condition (i.e., the condition that triggers the first timer) may include at least one of the following:

[0429] (i) UE#1 detected PDCCH during the first time period;

[0430] (ii) Y ms after the first time period is reached;

[0431] (iii) UE#1 failed to decode the received data packet during the first time period.

[0432] The numbers (i) to (iii) are for ease of description and understanding only and are not intended to limit this application. An example of condition (i) is given below.

[0433] As an example, UE#1 can start the first timer if condition (i) is met. In some examples, condition (i) may include: UE#1 detects the PDCCH within the last X ms of the first time period, where X can be greater than 0. For example, if UE#1 detects the PDCCH, it can initiate downlink or uplink initial scheduling. Thus, condition (i) can also be understood as UE#1 initiating downlink or uplink initial scheduling within the last X ms of the first time period. That is, the starting position of the first timer can be related to the initiation of initial scheduling.

[0434] For example, see Figure 5 In step (d), UE#1 initiates downlink or uplink initial scheduling within the last X ms of the first time period, which can start the first timer, thereby extending the first time period. The above example prevents UE#1 from entering a sleep state after initiating initial scheduling, thus ensuring data transmission for UE#1.

[0435] For example, the first time period described above can be implemented using one or more timers. For instance, the first time period can be implemented using a drx-duration (onDuration) timer or other timers. The first timer triggered by condition (i) can also be called an inactive timer or other names, which are not limited in this application.

[0436] In some examples, X ms can be configured by the first signaling (e.g., the first WUS), RRC signaling, or other signaling. In other examples, X ms can be predefined or preconfigured.

[0437] The following is an example of condition (ii).

[0438] As an example, if condition (ii) is met, UE#1 can start the first timer. That is, UE#1 can start the first timer after Y ms following the first time period. Here, Y can be greater than 0.

[0439] For example, see Figure 5 In (e), UE#1 starts the first timer after Y ms after the first time period, thereby extending the time period for UE#1 to monitor PDCCH, thus ensuring the data transmission of UE#1.

[0440] For example, the first time period mentioned above can be implemented by one or more timers.

[0441] In some examples, Y ms can be configured by first signaling (e.g., first WUS), RRC signaling, or other signaling. For example, the indication information of Y ms can be the first WUS sent before the first time period, the first WUS sent within the first time period, or another WUS sent within the first time period besides the first WUS. In other examples, Y ms can be predefined or preconfigured. Y can be the same as or different from X mentioned above.

[0442] Optionally, the duration of the first timer is shorter than the length of the first time period indicated by the first signaling (or RRC signaling). This allows for a shorter duration of the first timer, which is beneficial for UE#1 energy saving.

[0443] The following is an example of condition (iii).

[0444] As an example, if condition (iii) is met, UE#1 can start the first timer. That is, if UE#1 fails to decode the received data packet within the first time period, UE#1 can start the first timer.

[0445] For example, the aforementioned data packet could be a data packet from a hybrid automatic repeat request (HARQ) process. That is, if a data packet from a HARQ process is not successfully decoded within the first time period, UE#1 can start the first timer.

[0446] For example, the aforementioned first time period can be implemented using one or more timers. For instance, the first time period can be implemented using a drx-HARQ-round-trip time (RTT) timer. The first timer triggered by condition (iii) can also be called a drx-retransmission timer. As an example, if the drx-HARQ-RTT-Timer times out (i.e., the end of the first time period) and the data packet received by the HARQ process corresponding to the drx-HARQ-RTT-Timer is not successfully decoded, UE#1 can start a drx-RetransmissionTimer (i.e., the first timer) for the HARQ process. The aforementioned drx-RetransmissionTimer can represent the maximum time UE#1 waits for retransmission. Before the drx-RetransmissionTimer times out, UE#1 can monitor the PDCCH used for HARQ retransmission.

[0447] The following are some examples of first signaling indicating frequency domain resources.

[0448] In some examples, the first signaling also includes: first indication information. As an example, this first indication information indicates: frequency domain resources available for receiving data for UE#1, and / or frequency domain resources available for transmitting data for UE#1. For ease of description, these are collectively referred to below as frequency domain resources available for receiving / transmitting data for UE#1. Here, "receiving / transmitting" can be understood as receiving and / or transmitting.

[0449] For example, frequency domain resources that can be used to receive / transmit data can be understood as resources that may or may not be used to receive / transmit data. As an example, frequency domain resources that can be used to receive / transmit data may include frequency domain resources actually used for receiving / transmitting data.

[0450] For example, the aforementioned frequency domain resources may include carriers, or BWPs, etc. The aforementioned frequency domain resources may also be replaced with "bandwidth".

[0451] In some related schemes, the network device needs to first use a DCI to activate the dormant BWP / carrier, and then use a second DCI to schedule data transmission on the activated BWP / carrier. Specifically, the second DCI can be sent on the activated BWP / carrier to instruct the UE to transmit data.

[0452] In the above-mentioned scheme proposed in this application, the first indication information in the first signaling can indicate the frequency domain resources that can be used to receive / send data. Therefore, the network device can activate the frequency domain resources by issuing the first signaling and perform data transmission on the activated frequency domain resources, thereby realizing activation and data transmission more quickly, which helps UE#1 to quickly transmit data.

[0453] As an example, the first signaling carrying the first indication information can be either the first WUS or the first DCI. The first signaling carrying the first indication information can be sent on the dormant BWP of UE#1.

[0454] The following are some other examples of first signaling being the first DCI.

[0455] For example, the first DCI can be a DCI carried on the PDCCH, a DCI carried in the PDSCH (or a DCI that is carried along with the PDSCH), or a DCI carried in other channels or messages. As an example, the first DCI can be a first-level DCI or a second-level DCI. The first-level DCI can indicate the time-frequency position of the second-level DCI, and the second-level DCI can indicate the scheduling information of the PDSCH.

[0456] In some possible implementations, method 400 also includes S415 before S420.

[0457] S415, UE#1 receives a second WUS from the network device. Correspondingly, the network device sends a second WUS to UE#1.

[0458] As an example, the second WUS can be used to indicate whether the UE#1 monitors the first DCI associated with the second WUS. In other words, the second WUS can indicate whether the time period for which the UE#1 monitors the PDCCH is dynamic or static.

[0459] Specifically, if the time period for which the second WUS instructs UE#1 to monitor the PDCCH is dynamic, then UE#1 can monitor the first DCI associated with the second WUS, thereby obtaining the dynamic parameters of the first time period from the first DCI, and then monitoring the PDCCH within the first time period. If the time period for which the second WUS instructs UE#1 to monitor the PDCCH is static, then UE#1 may not monitor the first DCI associated with the second WUS, and UE#1 can monitor the PDCCH within the time period configured on the NW side (e.g., the aforementioned second time period).

[0460] As an example, there is an association between the second WUS and the first DCI. This association can be configured on the NW side, predefined, pre-configured, or configured in other ways. For example, the network device can instruct UE#1 on the time-frequency resources of the first DCI associated with the second WUS via RRC signaling.

[0461] As an example, the second WUS can be an LP-WUS or another type of WUS.

[0462] As an example, the second WUS may include 1 bit. A value of "1" indicates that UE#1 monitors the first DCI associated with the second WUS; a value of "0" indicates that UE#1 does not monitor the first DCI associated with the second WUS. Alternatively, a value of "0" indicates that UE#1 monitors the first DCI associated with the second WUS; a value of "1" indicates that UE#1 does not monitor the first DCI associated with the second WUS.

[0463] The second WUS can also include more than two bits, using additional bits to indicate whether UE#1 is monitoring the first DCI associated with the second WUS. Examples will not be repeated here.

[0464] In some examples, the second WUS can also instruct UE#1 whether to monitor the PDCCH in the first time period. For example, the second WUS can instruct UE#1 whether to monitor the first DCI and the PDCCH in the first time period.

[0465] In some examples, the second WUS can instruct UE#1 to monitor the first DCI associated with the second WUS; that is, the time period for instructing UE#1 to monitor the PDCCH can be dynamic. The first DCI can be located before or within the first time period, as described below as Example 1 and Example 2 of the first DCI.

[0466] First DCI Example 1:

[0467] In the first DCI example 1, the first signaling is the first DCI received before the first time period. For ease of understanding, the following will be combined with... Figure 6 (a) introduces the first DCI example 1.

[0468] Figure 6 These are schematic diagrams illustrating two examples of the first DCI provided in the embodiments of this application. See also Figure 6 In (a), the time domain resources of the first DCI can be located before the first time period, that is, UE#1 can receive the first DCI before the first time period.

[0469] As an example, the first DCI may carry at least one of information (1) to information (4) or the indication information of the second offset, as detailed in the previous description, and will not be repeated here.

[0470] Based on the above scheme, the second WUS can instruct UE#1 whether to monitor the first DCI. If the second WUS instructs UE#1 not to monitor the first DCI, UE#1 can save the overhead of monitoring the first DCI, and the network device does not need to send the first DCI, thereby reducing the energy consumption of UE#1 and the network device. If the second WUS instructs UE#1 to monitor the first DCI, UE#1 receives the first DCI and monitors the PDCCH within the first time period indicated by the first DCI, thus effectively transmitting data. The first DCI is located before the first time period, allowing the first DCI to flexibly determine its position in the time domain, which helps to flexibly match actual service requirements.

[0471] As an example, the time-domain interval between the second WUS and the first DCI can be related to the user's capabilities. Exemplarily, the time-domain interval between the second WUS and the first DCI can be represented by a third offset. This third offset can be the time offset between the end position (or start position) of the second WUS and the start position of the first DCI.

[0472] For example, the capabilities of the aforementioned users can be related to the time it takes for the user to process signals (e.g., WUS). Taking UE#1 as an example, the longer UE#1 takes to process WUS, the larger the third offset can be, thus reserving more time for UE#1 to process the second WUS; the shorter the time UE#1 takes to process WUS, the smaller the third offset can be, thus enabling UE#1 to enter the wake-up state as quickly as possible (i.e., the interval between the first time period and the second WUS should be as small as possible), ensuring timely data transmission, that is, reducing data transmission latency.

[0473] In some examples, a user (e.g., UE#1) can report its capabilities to the network device. The network device can configure a third offset based on the user's capabilities, or in other words, determine and issue indication information for the third offset based on the user's capabilities. Users with different capabilities may receive different indication information for the third offset. For example, the stronger a user's capability (or the shorter the WUS processing time), the smaller the third offset indication information received by that user can indicate. Conversely, the weaker a user's capability (or the longer the WUS processing time), the larger the third offset indication information received by that user can indicate.

[0474] As an example, the time-domain interval between the first DCI and the first time period can be related to the user's capabilities. For instance, the time-domain interval between the first DCI and the first time period can be represented by the first offset mentioned earlier. See the preceding text for details, which will not be repeated here. The difference from the previous example is that the previous example used the first signaling being the first WUS, while this example uses the first signaling being the first DCI.

[0475] First DCI Example 2:

[0476] In the first DCI example 2, the first signaling is the first DCI received within that first time period. For ease of understanding, the following will be combined with... Figure 6 (a) introduces the first DCI example 2.

[0477] See Figure 6 In (b), the time domain resources of the first DCI can be located within the first time period, that is, UE#1 can receive the first DCI within the first time period.

[0478] In some examples, the second WUS can also indicate the start position of the first time period. For example, the second WUS can indicate the absolute start position of the first time period in the time domain (e.g., the index of the first symbol of the first time period). As another example, the second WUS can indicate information about a fourth offset. This fourth offset can be the offset in the time domain between the time domain resource of the second WUS and the start position of the first time period. The specific description and information (1) are similar to the description of the first offset in Example 1, except that the first signaling mentioned above can be replaced by the second WUS here. For example, see Examples 1 to 3 for the first offset, which will not be repeated here.

[0479] In other examples, the starting position of the first time period may be configured by the network device through other signaling (e.g., RRC signaling), determined by predefined rules, determined by pre-configured rules, or determined by other means.

[0480] In some examples, the first DCI can indicate the end position of the first time period. For example, the first DCI can indicate the absolute end position of the first time period in the time domain (e.g., the index of the last symbol of the first time period). Another example is that the first DCI can indicate the offset of the end position of the first time period relative to the first DCI. Yet another example is that the first DCI can indicate the length of the first time period, thereby indirectly indicating the end position of the first time period.

[0481] In some examples, the first DCI may also carry at least one of information (2) to information (4) or the indication information of the second offset, as detailed in the previous descriptions, which will not be repeated here.

[0482] Based on the above scheme, the second WUS can instruct UE#1 whether to monitor the first DCI. Thus, if the second WUS instructs UE#1 not to monitor the first DCI, UE#1 can save the overhead of monitoring the first DCI, and the network device does not need to issue the first DCI, thereby reducing the energy consumption of UE#1 and the network device. If the second WUS instructs UE#1 to monitor the first DCI, UE#1 receives the first DCI and monitors the PDCCH within the first time period indicated by the first DCI, thereby effectively transmitting data. In the above scheme, UE#1 can quickly enter the wake-up state through the second WUS and monitor the PDCCH without indicating the time to end the wake-up state (i.e., the end position of the first time period). Then, UE#1 can receive the first DCI in the wake-up state (i.e., within the first time period) and determine the time to end the wake-up state through the first DCI. Therefore, the above scheme can flexibly control the duration of UE#1's wake-up state while ensuring timely wake-up of UE#1. This helps to flexibly match the needs of actual services. In some other examples of the first DCI example 2, the second WUS can indicate a second time period. For example, the second WUS can include the indication information of the second time period mentioned above. The first DCI can carry information (1) to update the second time period to the first time period. For details, please refer to the relevant description of information (1) in Example 2 above, which will not be repeated here.

[0483] In some other examples of the first DCI example 2, the second WUS may carry information (1); the first DCI may carry at least one of the following: information (2) to (4), or indication information of the second offset. As an example, UE#1 may receive the first DCI by monitoring the PDCCH on the frequency domain resources of the second WUS. In other words, the frequency domain resources of the second WUS and the frequency domain resources of the first DCI may be the same.

[0484] In some examples of the first DCI example 1 and the first DCI example 2, the second WUS can also indicate the time-frequency resources of the PDCCH. For example, the second WUS can include the ID of the time-frequency resource configuration of the PDCCH, which helps to reduce the power consumption of the UE in blind detection of the PDCCH and reduce the UE's energy consumption.

[0485] As an example, the PDCCH indicated by the second WUS may or may not carry the aforementioned first DCI, and this application does not impose any limitation on it. In other words, this application does not impose any limitation on the PDCCH indicated by the second WUS.

[0486] Based on the above scheme, UE#1 can narrow the range of time and frequency resources of blind detection DCI based on the time and frequency resources of PDCCH indicated by the second WUS, thereby reducing blind detection overhead, reducing blind detection complexity, and reducing the power consumption of UE#1.

[0487] In some examples of the first DCI example 1 and the first DCI example 2, the second WUS is also used to instruct the UE#1 to monitor the second DCI for scheduling data transmission on the PDCCH during the first time period.

[0488] In other words, the network device can instruct UE#1 via the second WUS to detect two DCIs within the first time period.

[0489] In this application, the first DCI can also be replaced by the first PDCCH, and the second DCI can also be replaced by the second PDCCH.

[0490] The following is an example of the periodic distribution of the PDCCH monitoring time period of UE#1.

[0491] In some examples, the first time period can be one of multiple periodicly distributed time periods available for PDCCH monitoring. For example, "a time period available for PDCCH monitoring" can be understood as a time period capable of being used for PDCCH monitoring; however, this application does not limit whether this time period is ultimately used for PDCCH monitoring. That is, a time period available for PDCCH monitoring is not necessarily ultimately used for PDCCH monitoring.

[0492] The time-frequency resources for the first signaling can be either before or within a periodically distributed time period available for PDCCH monitoring. Two examples are given below, denoted as Periodic Example 1 and Periodic Example 2, respectively.

[0493] Example of a cycle:

[0494] In cycle example 1, the first signaling can be used to indicate the first time period within the current cycle. For ease of understanding, the following example demonstrates... Figure 7 Example 1 of the cycle is described in (a).

[0495] Figure 7 This is a schematic diagram illustrating the time period for monitoring the PDCCH as provided in the embodiments of this application, using the first signaling indication method. See also... Figure 7 In (a), the monitoring timing of WUS (e.g., conventional LP-WUS, the second WUS in this application, or the first WUS in this application) and the "time period available for PDCCH monitoring" can be periodically distributed. One WUS monitoring timing can correspond to one time period available for PDCCH monitoring. One WUS monitoring timing and the first time period available for PDCCH monitoring after that WUS can belong to one cycle; for ease of understanding, this cycle is referred to below as the dynamic indication cycle.

[0496] Network devices can send the first signaling message within a certain dynamic indication period, which can be called the current period of the first signaling message.

[0497] In cycle example 1, the first signaling can be used to indicate the first time period within the current cycle. That is, the first signaling in a certain dynamic indication cycle can indicate the first time period in that dynamic indication cycle used for monitoring PDCCH.

[0498] Example of a cycle 2:

[0499] In cycle example 2, the first signaling can be used to indicate the first time period within the cycle following the current cycle. The meaning of the current cycle is explained in cycle example 2 above and will not be repeated here. For ease of understanding, the following example uses the first signaling indicating the first time period within the cycle following the current cycle as an example, combined with... Figure 7 Example 2 of the cycle is introduced in (b) of the text.

[0500] See Figure 7 In (b), the monitoring timing of WUS (e.g., conventional LP-WUS, the second WUS in this application, or the first WUS in this application) and the "time period available for PDCCH monitoring" can be periodically distributed. Specifically, one WUS monitoring timing can correspond to one time period available for PDCCH monitoring. Furthermore, one WUS monitoring timing and the first time period available for PDCCH monitoring after that WUS can belong to a dynamic indication cycle.

[0501] The following is combined with Figure 7 This section introduces some examples of periodic example 1 and periodic example 2.

[0502] In some examples, the first signaling can be the first WUS, in which case the first WUS can be located at Figure 7 The WUS monitoring timing shown in the current cycle is indicated by the first WUS dynamic indication of the first time period.

[0503] In other examples, the first signaling can be a combination of a first WUS and a second signaling. As an example, the second signaling can be one of the following, or any combination thereof: a first DCI, MAC CE, or SIB. In this case, the first WUS can be located at... Figure 7 The WUS monitoring timing shown in the current cycle indicates that the second signaling can be located in... Figure 7 The time-domain resources of the second signaling shown, or other locations.

[0504] In some further examples, the first signaling can be a combination of the second WUS and the second signaling. As an example, the second signaling can be a first DCI, or a combination of multiple signaling protocols including the first DCI. For instance, the second signaling may also include at least one of the following: MAC CE, or SIB. In this case, the first WUS can be located at... Figure 7 The WUS monitoring timing shown in the current cycle indicates that the second signaling can be located in... Figure 7 The time-domain resources of the second signaling shown, or other locations.

[0505] In some further examples, the first signaling can be one or a combination of the following: first DCI, MAC CE, or SIB. As an example, MAC CE can be carried in PDSCH or other channels. In this case, the WUS in the current cycle can be a traditional LP-WUS. The first signaling can be located in... Figure 7 The time-domain resources of the second signaling shown, or other locations.

[0506] The following are some examples where the first signaling is SIB.

[0507] In some examples, the first signaling is an SIB, which can be used to indicate a first time period. For example, the SIB can carry at least one of the following: information (1) to information (4), or indication information of a second offset. For ease of description, the above information can be collectively referred to as the dynamic parameters for monitoring the PDCCH.

[0508] Optionally, the SIB is also used to configure the time-frequency resources of the WUS (e.g., LP-WUS) and / or the period of the WUS.

[0509] Based on the above scheme, the SIB can carry dynamic parameters of the monitored PDCCH. This scheme facilitates disconnected UEs in quickly obtaining the dynamic parameters of the monitored PDCCH in both connected and / or disconnected states. This is because, without this scheme, disconnected UEs would need to first establish an access connection and then obtain the dynamic parameters of the monitored PDCCH through other signaling. Therefore, this scheme allows disconnected UEs to obtain the dynamic parameters of the monitored PDCCH more quickly, thereby enabling faster data transmission and reducing the energy consumption of signaling interactions.

[0510] In other examples, the first signaling may be a combination of one or more of the following: first WUS, MAC CE, or first DCI. Optionally, the network device may also send an SIB to UE#1, which may indicate (e.g., LP-WUS) the time-frequency resources and / or the period of WUS. In other words, the SIB in the above optional schemes may not be part of the first signaling.

[0511] The following are some examples of NW side configurations for monitoring multiple time periods of PDCCH, referred to as Configuration Example 1 to Configuration Example 7.

[0512] Configuration Example 1:

[0513] In some possible implementations, method 400 also includes S405a prior to S420.

[0514] S405a, UE#1 receives first configuration information from the network device. As an example, this first configuration information is used to configure at least one third time period. Correspondingly, the network device sends the first configuration information to UE#1.

[0515] As an example, each of the above-mentioned at least one third time period corresponds one-to-one with at least one identifier. For example, third time period #1 corresponds to identifier #1, third time period #2 corresponds to identifier #2, and so on. A third time period can be one or more time periods, similar to the description of the first time period above, and will not be repeated here.

[0516] In some examples, the correspondence between the aforementioned at least one third time period and at least one identifier may be explicitly or implicitly indicated by the first configuration information.

[0517] The aforementioned at least one third time period may include the first time period. The identifier corresponding to the first time period may be denoted as the first identifier, which may belong to the identifiers corresponding to the aforementioned at least one third time period.

[0518] In some examples of Process Example 1, the first signaling may include a first identifier, thereby indicating a first time period. For example, UE#1 may determine the first time period corresponding to the first identifier based on the first identifier and a pre-stored correspondence between the aforementioned at least one third time period and at least one identifier.

[0519] In some examples, S405a can be executed multiple times according to business needs. For instance, the network device can configure a third time period #1 and a third time period #2 using the first configuration information. The network device can then configure a third time period #3 using the first configuration information again. The third time period #3 can be understood as a newly added third time period. The term "newly added" can also be replaced with "activated".

[0520] In some examples, the first identifier can be a single identifier. The network device can configure multiple third time periods through first configuration information and indicate an identifier (i.e., the first identifier) ​​via first signaling, which corresponds to the first time period among the multiple third time periods.

[0521] In other examples, the first identifier can be multiple identifiers. The network device can configure multiple third time periods through first configuration information and indicate multiple identifiers through first signaling. These multiple identifiers correspond one-to-one with multiple time periods (collectively referred to as first time periods) within the multiple third time periods. That is, the first time period can be multiple time periods; for ease of description, these multiple time periods are denoted as time period #1 to time period #P, where P can be an integer greater than 1. There is a one-to-one correspondence between time period #1 to time period #P and identifiers #1 to #P.

[0522] As an example, time periods #1 to #P (or identifiers #1 to #P) can satisfy at least one of the following: time-division multiplexing, space-division multiplexing, or frequency-division multiplexing. Time-division multiplexing can be understood as at least two time periods from #1 to #P having different positions in the time domain. Space-division multiplexing can be understood as at least two time periods from #1 to #P having different spatial parameters. Frequency-division multiplexing can be understood as at least two time periods from #1 to #P having different frequency resources.

[0523] The spatial parameters corresponding to the time period can be understood as the spatial parameters used by UE#1 to monitor the PDCCH during that time period, such as the beam. The frequency domain resources corresponding to the time period can be understood as the frequency domain resources used by UE#1 to monitor the PDCCH during that time period.

[0524] For example, within time period #1 to time period #P, the frequency domain resources corresponding to different time periods may be different. These frequency domain resources may include carriers, frequency bands, etc. Alternatively, within identifiers #1 to #P, the frequency domain resources corresponding to different identifiers may be different.

[0525] For example, the first signaling may include P fields, each corresponding one-to-one with a time period #1 to #P, or in other words, each corresponding one-to-one with an identifier #1 to #P. As an example, each of the P fields may include 1 bit. A value of 1 indicates that the corresponding identifier (or time period) is activated; a value of 0 indicates that the corresponding identifier (or time period) is deactivated. These P fields can be understood as a bitmap. When the number of identifiers (or time periods) is large (e.g., greater than two), the bitmap's indication overhead is smaller compared to activating and deactivating these identifiers (or time periods) using codewords.

[0526] For example, the first signaling may include one or more codewords. A codeword can indicate an activation or deactivation flag. For instance, with a 2-bit codeword, "00" can represent activation or deactivation flag #1 (or time period #1), "01" can represent activation or deactivation flag #2 (or time period #2), "10" can represent activation or deactivation flag #3 (or time period #3), and "11" can represent activation or deactivation flag #4 (or time period #4). When the number of flags (or time periods) is small (e.g., 1 or 2), the overhead of codeword indication is smaller compared to activating and deactivating the above flags (or time periods) via a bitmap.

[0527] In some examples, each of the at least one third time period can be periodic. For example, each of the at least one third time period can represent multiple time periods with a periodic distribution. Thus, the first time period can also be multiple time periods with a periodic distribution; in other words, the time period corresponding to the first identifier can be multiple time periods with a periodic distribution.

[0528] As an example, the first configuration information can be used to configure a periodically distributed third time period. The first signaling can instruct the activation or deactivation of the third time period corresponding to that first signaling. For example, the third time period corresponding to the first signaling can be the first of at least one third time period following the first signaling. That is, the third time period corresponding to the first signaling can be located after the first signaling. Another example is that the third time period corresponding to the first signaling can be the third time period in which the first signaling is located. That is, the first signaling can be located within the third time period. As a specific example, the first signaling can be located within the first Q time-domain units of the third time period, where Q can be a positive integer. For example, the first signaling can be located in the first symbol or the first Q symbols of the third time period.

[0529] The time period during which the first signaling is activated can be recorded as the first time period.

[0530] For example, the first signaling may include 1 bit. For instance, a value of 1 for this bit indicates a third time period after activating the first signaling; a value of 0 for this bit indicates a third time period after deactivating the first signaling. Alternatively, a value of 0 for this bit indicates a third time period after activating the first signaling; a value of 1 for this bit indicates a third time period after deactivating the first signaling.

[0531] For example, a value of 1 for this bit indicates that the third time period following the first signaling is switched from active to inactive (or from inactive to active); a value of 0 for this bit indicates no switching. Alternatively, a value of 0 for this bit indicates that the third time period following the first signaling is switched from active to inactive (or from inactive to active); a value of 1 for this bit indicates no switching.

[0532] To facilitate understanding, the following will be combined with Figure 8 This section introduces some examples of how the first signaling activates the first time period.

[0533] Figure 8 This is a schematic diagram illustrating the activation of a first time period by first signaling according to an embodiment of this application. See also... Figure 8 In (a), the first signaling and the third time period can be periodically distributed in a one-to-one correspondence. The first signaling can activate the third time period following the first signaling, or deactivate the third time period following the first signaling.

[0534] See Figure 8 In (b) of the above, the third time period can be periodically distributed, and the first signaling and the third time period do not have to correspond one-to-one, or in other words, they can be decoupled. The first signaling can activate the third time period following the first signaling, or deactivate the third time period following the first signaling.

[0535] As a specific example, the third time segment can be fixed in the second half of each system frame, or in the second half of the latter system frame out of every two system frames.

[0536] Based on the above scheme, the network device can pre-configure at least one third time period corresponding to at least one identifier for UE#1. In this way, the network device can subsequently indicate the first time period used by UE#1 through the identifier corresponding to the first time period, thereby reducing the overhead of the first signaling.

[0537] Configuration Example 2:

[0538] In some possible implementations, method 400 also includes S405b prior to S420.

[0539] In step S405b, UE#1 receives second configuration information from the network device. As an example, this first configuration information is used to configure a third time period and a first time period. Correspondingly, the network device sends the second configuration information to UE#1.

[0540] As an example, at least one parameter differs between the parameters of the third time period and the parameters of the first time period. For example, one or more parameters in the time domain, frequency domain, spatial domain, or power domain may differ. Specifically, the first time period may have a shorter period, and the third time period may have a longer period.

[0541] As an example, the first configuration information is also used to configure UE#1 to monitor the PDCCH using a third time period. As another example, UE#1 may be predefined, preconfigured, or otherwise configured by the network device to monitor the PDCCH using a third time period.

[0542] In some examples, the first signaling may include second indication information. For instance, the second indication information may be used to indicate that the time period during which the UE#1 waits to monitor the PDCCH is switched from the third time period to the first time period.

[0543] In other words, in configuration example 2, the network device can be configured with two time periods, and the first signaling can indicate a switch from one time period to another.

[0544] As a concrete example, the second indication information may include 1 bit. For instance, a value of "0" for this bit could instruct UE#1 to switch from the third time period to the first time period; a value of "1" could instruct UE#1 to continue using the third time period. In short, a value of "0" for this bit can indicate "switch," and a value of "1" can indicate "no switch." Alternatively, a value of "1" for this bit can indicate "switch," and a value of "0" can indicate "no switch."

[0545] Based on the above scheme, the network device can instruct UE#1 to switch the time period for monitoring the PDCCH through the second indication information, thereby flexibly changing the time period for UE#1 to monitor the PDCCH. In some examples, the second indication information can be implemented with 1 bit, thus reducing signaling overhead.

[0546] Configuration Example 3:

[0547] For example, the first signaling can activate or deactivate the entire time period used for monitoring the PDCCH within the first time window. The first time period can be located within the first time window. As an example, a time period located within the first time window can be understood as either completely falling within the first time window, or partially falling within it.

[0548] As an example, the entire time period used for monitoring PDCCH within the first time window can be configured by the network device through RRC signaling, indicated by WUS, DCI, SIB or MAC CE, or it can be predefined or preconfigured.

[0549] In some examples, the entire time period used for monitoring the PDCCH within the first time window can be periodic. In other examples, the entire time period used for monitoring the PDCCH within the first time window can be non-periodic.

[0550] For example, see Figure 8 In (c), the first signaling can activate the entire time period within the first time window used for monitoring the PDCCH. As an example, the length of the first time window can be 20ms or other values.

[0551] The meaning of the first time period in the UE-level example is explained below.

[0552] In some examples, this first time period is the active-time period in the DRX. For instance, a DRX cycle may include one or more active periods (or, DRX active periods). As an example, the DRX cycle, the length of the active period, and the length of the inactive period can be indicated or changed by the first signaling.

[0553] For example, the first time period can be replaced with DRX parameters. For instance, DRX parameters may include at least one of the following: period, length of the enabled time period, and parameters from other DRX configurations (DRX-Config, DRX-ConfigExt-v1700, DRX-ConfigExt2-v1800). As an example, DRX-Config, DRX-ConfigExt-v1700, or DRX-ConfigExt2-v1800 may include at least one of the following parameters: drx-HARQ-RTT-TimerDL, drx-HARQ-RTT-TimerUL, drx-NonIntegerLongCycleStartOffset, drx-NonIntegerShortCycle, drx-TimeReferenceSFN, shortDRX, drx-onDurationTimer, drx-InactivityTimer, drx-HARQ-RTT-TimerUL, drx-RetransmissionTimerDL, drx-RetransmissionTimerUL, drx-LongCycleStartOffset (long cycle start offset), drx-ShortCycle (short cycle), drx-ShortCycleTimer (short cycle timer), or drx-SlotOffset (slot offset), etc. These parameters can be found in the relevant section of 3GPP standard protocol 38.331, and will not be detailed here.

[0554] In other examples, this first time period belongs to a first set. This first set includes multiple time periods available for UE#1 to wait for PDCCH monitoring.

[0555] For example, these multiple time periods are distributed non-interval in the time domain. Another example is that these multiple time periods are distributed non-periodically in the time domain. Yet another example is that two of the multiple time periods have different lengths.

[0556] Based on the above scheme, the first time period can be adapted to the traditional activation period used for monitoring and control channels. Alternatively, the first time period can consist of multiple continuously distributed, non-periodic, or irregular time periods, thereby flexibly matching the needs of actual services and reducing energy consumption.

[0557] The following section introduces some solutions applicable to cell-level examples.

[0558] In some examples, this first time period is the active-time in cell-level discontinuous transmission (DTX) / DRX (cell DTX / DRX). The aforementioned DTX / DRX can be understood as "DTX and DRX".

[0559] As an example, UE#1 can be configured with periodic cell-level DTX / DRX patterns, which can indicate active and non-active periods. During the active period, UE#1 can wait to receive information on the PDCCH or SPS timing, and transmit information on the SR or CG. The non-active period can also be called a dormant period or other names, which are not limited in this application.

[0560] In other examples, the first time period can be the active period in the cell-level DTX or the active period in the cell-level DRX. UE#1 can wait to transmit information on the SR or CG channel during the active period in the cell-level DTX. UE#1 can wait to receive information on the PDCCH or SPS timing during the active period in the cell-level DRX.

[0561] As an example, if the cell-level DRX is configured and activated in the first cell, UE#1 may not send information on the CG channel (or CG resource) or send SR during the non-active period of the cell-level DRX.

[0562] In some other examples, the first time period belongs to a first set. This first set includes: time periods available for the first cell to wait for information on the PDCCH or SPS timing, and / or time periods available to wait for information on the SR or CG channel.

[0563] As an example, all UEs in the first cell can use the aforementioned "time period available for waiting to receive information on the PDCCH or SPS timing" to wait for information on the PDCCH or SPS timing. However, this application does not limit whether all UEs in the first cell actually use the aforementioned time period. For example, part of the "time period available for waiting to receive information on the PDCCH or SPS timing" may be deactivated by the first signaling. In this way, all UEs in the first cell can sleep during the aforementioned deactivated time period, that is, they will not receive information on the PDCCH or SPS timing during the deactivated time period.

[0564] As an example, all UEs in the first cell can use the aforementioned "time period available for waiting to transmit information on the SR or CG channel" to wait for the transmission of information on the SR or CG channel. However, this application does not limit whether all UEs in the first cell actually use the aforementioned time period. For example, part of the "time period available for waiting to transmit information on the SR or CG channel" may be deactivated by the first signaling. In this way, all UEs in the first cell can sleep during the aforementioned deactivated time period, that is, they will not transmit information on the SR or CG channel during the deactivated time period.

[0565] For example, multiple time periods in the first set are non-interval distributed in the time domain. Another example is that multiple time periods in the first set are non-periodic distributed in the time domain. Yet another example is that two time periods in the first set have different lengths.

[0566] Based on the above scheme, the first time period can be adapted to the traditional activation period used at the cell level. Alternatively, the first time period can consist of multiple time periods that are continuously distributed, non-periodic, or irregular, thereby flexibly matching the needs of actual business operations.

[0567] In some examples, all UEs in the first cell are allowed to transmit SR, buffer status report (BSR), delay status report (DSR), physical random access channel (PRACH), low-power signal (e.g., LP-WUS), or narrowband signal (e.g., the transmission bandwidth of which is less than 5MHz or 10MHz) during inactive time periods (e.g., one or more time periods outside the first time period).

[0568] In some examples, all UEs in the first cell are allowed to receive low-power signals (e.g., LP-WUS) or narrowband signals (e.g., signals with a receive bandwidth of less than 5MHz or 10MHz) during inactive periods.

[0569] The following, combined with Figures 9 to 12 This application provides a detailed description of the communication device provided in the embodiments. The descriptions of the device embodiments correspond to the descriptions of the method embodiments; therefore, for content not described in detail, please refer to the above method embodiments. For the sake of brevity, some content will not be repeated.

[0570] This application embodiment can divide the communication device into functional modules according to the above method example. For example, each function can be divided into its own functional modules, or two or more functions can be integrated into one processing module. The integrated modules can be implemented in hardware, software, or a combination of both. The module division in this application embodiment is illustrative and only represents one logical functional division; other division methods may be used in actual implementation. The following description uses the division of functional modules according to each function as an example.

[0571] Figure 9 This is an exemplary block diagram of the communication device 1000 provided in the embodiments of this application.

[0572] like Figure 9 As shown, for example, the communication device 1000 may include a chip system 1010, a memory 1020, a bus 1030, a power management module 1040, or a transceiver 1050, etc.

[0573] The chip system 1010 can be an integrated circuit chip with signal processing capabilities. In implementation, each step of the above method can be completed through integrated logic circuits in the hardware of the chip system 1010 or through software instructions.

[0574] As an example and not a limitation, the chip system 1010 may include circuitry or chips responsible for signal processing (such as a modem chip, also known as a baseband chip, or a system-on-chip (SoC) chip or system-in-package (SIP) chip containing a modem core).

[0575] Optionally, the chip system 1010 may also include a memory (such as a cache) for storing instructions and data. In some embodiments, the memory in the chip system 1010 is a cache memory. This memory can store instructions or data that the chip system 1010 has just used or that are used repeatedly. If the chip system 1010 needs to use the instruction or data again, it can directly retrieve it from the memory. This avoids repeated accesses, reduces the waiting time of the chip system 1010, and thus improves the efficiency of the system.

[0576] In some embodiments, the chip system 1010 may include one or more interfaces. Interfaces may include an inter-integrated circuit (I2C) interface, an inter-integrated circuit sound (I2S) interface, a pulse code modulation (PCM) interface, a universal asynchronous receiver / transmitter (UART) interface, a mobile industry processor interface (MIPI), a general-purpose input / output (GPIO) interface, a subscriber identity module (SIM) interface, and / or a universal serial bus (USB) interface, etc.

[0577] The memory 1020 may include random access memory (RAM) and read-only memory (ROM). The memory 1020 may store computer-readable, computer-executable code, including instructions that, when executed, cause the processor to perform the various functions described in this application.

[0578] Optionally, the code may include instructions for implementing various aspects of the embodiments of this application, such as instructions for receiving a first signaling. The code may be stored in a non-transitory computer-readable medium such as system memory or other types of memory. In some cases, the code may not be directly executable by the chip system 1010, but may enable a computer (e.g., at compile and execution time) to perform the functions described in this application. In some cases, memory 1020 may contain a basic I / O system that controls basic hardware or software operations, such as interaction with peripheral components or devices.

[0579] For example, the chip system 1010 executes various functional applications and data processing of the communication device 1000 by running instructions stored in the memory 1020. For instance, when the communication device 1000 transfers files with other devices (which may also be terminals or access network devices), the chip system 1010 of the communication device 1000 can call the computer-executable program code stored in the memory 1020 to implement the communication method provided in the embodiments of this application.

[0580] In addition, the memory 1020 can be integrated into the chip system 1010 or independent of the chip system 1010.

[0581] For example, bus 1030 may be USB for supporting communication between various parts of communication device 1000.

[0582] The power management module 1040 is used to receive charging input from the charger. Optionally, the power management module 1040 can also supply power to the communication device 1000 while charging it (e.g., the battery module of the communication device 1000). By way of example and not limitation, the power management module 1040 can also supply power to other devices besides the communication device 1000.

[0583] Transceiver 1050 can communicate bidirectionally via one or more antennas, a wired link, or a wireless link. For example, transceiver 1050 can represent a wireless transceiver and can communicate bidirectionally with another wireless transceiver. Transceiver 1050 may also include a modem for modulating packets and providing the modulated packets to the antenna for transmission, and for demodulating packets received from the antenna. Transceiver 1050 may include a receiver and a transmitter, the receiver performing the function of receiving information and the transmitter performing the function of transmitting information.

[0584] In some cases, a wireless device may include a single antenna. However, in other cases, a device may have more than one antenna, such as... Figure 9 Antennas 1 and 2 shown may be capable of simultaneously transmitting or receiving multiple wireless transmissions. Exemplarily, antennas 1 and 2 are used to transmit and receive electromagnetic wave signals. Each antenna in the communication device 1000 can be used to cover one or more communication frequency bands. Different antennas can also be multiplexed to improve antenna utilization. For example, antenna 1 can be multiplexed as a diversity antenna for a wireless local area network. In some other embodiments, the antennas can be used in conjunction with a tuning switch. The communication device 1000 can transfer files to other devices via wireless communication functions.

[0585] In one design, the communication device 1000 may correspond to the first terminal in the above method embodiment.

[0586] The device 1000 can implement the steps or processes corresponding to those executed by the first terminal in the above method embodiments. The transceiver 1050 can be used to execute operations related to the transmission and reception of the first terminal in the above method embodiments, such as executing step S520. The chip system 1010 can be used to execute processing-related operations of the first terminal in the above method embodiments, such as S540.

[0587] In another design, the communication device 1000 may correspond to the network-side device in the above method embodiment.

[0588] The device 1000 can implement the steps or processes executed on the network side corresponding to the method embodiments above. The transceiver 1050 can be used to perform network-side transmission and reception related operations in the method embodiments above, such as executing step S520 in the method embodiments above. The chip system 1010 can be used to perform network-side processing related operations in the method embodiments above.

[0589] In a design where the communication device 1000 corresponds to the first terminal, the communication device 1000 may include, for example: Figure 9 The short-range communication module 1064, sensor 1061, display 1062, or camera 1063 shown are examples of such modules.

[0590] The short-range communication module 1064 may include modules that support short-range communication, such as Wi-Fi and Bluetooth.

[0591] For example, sensor 1061 may include pressure sensor, gyroscope sensor, barometric pressure sensor, magnetic sensor, accelerometer, distance sensor, proximity sensor, fingerprint sensor, temperature sensor, touch sensor, ambient light sensor, bone conduction sensor, etc.

[0592] For example, the display 1062 is used to display images, videos, etc. The display includes a display panel. The display panel can be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a mini light-emitting diode (LED), a microLED, a microOLED, a quantum dot light-emitting diode (QLED), etc. For example, in this embodiment, the display can be used to display the interface required by the communication device 1000. For example, the communication device 1000 implements the display function through a graphics processing unit (GPU), a display, and an application processor. The GPU is a microprocessor for image processing, connected to the display and the application processor. The GPU is used to perform mathematical and geometric calculations and for graphics rendering. The chip system 1010 may include one or more GPUs that execute program instructions to generate or change display information.

[0593] For example, camera 1063 is used to acquire images, videos, etc.

[0594] Understandable Figure 9 The structure shown does not constitute a specific limitation on the communication device 1000. The specific structure of the terminal equipment and / or access network equipment can be referred to Figure 9 As shown. In some embodiments, the communication device 1000 may also include a... Figure 9 This could mean having more or fewer components, combining some components, separating some components, or having different component arrangements. Or, Figure 9 Some of the components shown can be implemented in hardware, software, or a combination of software and hardware. Terminal devices and / or access network devices can be implemented in… Figure 9 The components were added or removed based on the given structure.

[0595] Figure 10 This is a schematic block diagram of the communication device 2000 provided in the embodiments of this application.

[0596] like Figure 10As shown, the communication device 2000 may include a baseband unit 2010, which can communicate with external devices via a cellular radio frequency (RF) transceiver 2020 (e.g., if the communication device 2000 is a terminal device, the baseband unit 2010 can communicate with access network devices via the cellular RF transceiver 2020; or, if the communication device 2000 is an access network device, the baseband unit 2010 can communicate with terminal devices and / or core network devices via the cellular RF transceiver 2020).

[0597] By way of example, baseband unit 2010 may include computer-readable medium / memory. Baseband unit 2010 may be responsible for general processing, including the execution of software stored on computer-readable medium / memory. When executed by baseband unit 2010, the software causes baseband unit 2010 to perform the various functions described above. Computer-readable medium / memory may also be used to store data manipulated by baseband unit 2010 when executing the software.

[0598] Optionally, the baseband unit 2010 further includes a receiving unit 2011, a management unit 2012, and a transmitting unit 2013. When the communication device 2000 is applied to the first terminal, the management unit 2012 may include one or more of these components. Figure 10 The sub-units shown are as follows. For example, a PDCCH monitoring sub-unit, which can be used to perform the operation of monitoring the PDCCH in the above method embodiments. The units within the management unit 2011 can be stored in a computer-readable medium / memory and / or configured as hardware within the baseband unit 2010. The receiving unit 2011 and the transmitting unit 2013 can be referred to as transceiver units.

[0599] When the communication device 2000 is used to implement the functions of the first terminal in the above method embodiments, the receiving unit 2011 is used to execute the receiving step of the first terminal, the sending unit 2013 is used to execute the sending step of the first terminal, and the management unit 2012 is used to execute the processing step of the first terminal.
