Description

Energy-saving method and related device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on February 8, 2024, with application number 202410178309.3 and application name “Energy-saving methods and related devices”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of wireless communications, and in particular to an energy-saving method and related devices. Background Art

[0003] Network energy conservation is crucial for environmental sustainability, reducing environmental impacts (such as greenhouse gas emissions), and saving operating costs. With the proliferation of fifth-generation mobile communication technology (5G) across various industries and geographic regions, more advanced services and applications, often requiring very high data rates (such as extended reality (XR)), are leading to denser networks using more antennas, greater bandwidth, and more frequency bands. Therefore, the environmental impact of 5G needs to be managed, and novel solutions need to be developed to improve network energy conservation.

[0004] In related technologies, a base station instructs a terminal device through dedicated radio resource control (RRC) signaling that the system information block 1 (SIB1) of the secondary cell (SCell) includes synchronization signal block (SSB) information. The beam broadcast information of the secondary cell is broadcast periodically, where the SSB information includes the beam period and the beam time domain position (SSBinBurst). This process results in high wireless access energy consumption. Summary of the Invention

[0005] The present application provides an energy-saving method and related devices to reduce network energy consumption of wireless access.

[0006] On the first aspect, the present application provides an energy-saving method, which can be executed by a terminal device, or by a component configured in the terminal device (such as a chip, a chip system, etc.), or by a logic module or software that can realize all or part of the terminal device functions. The present application does not limit this.

[0007] Optionally, the method includes: obtaining first information, the first information being used to indicate a non-broadcasting state of the SCell in the SSB; and performing energy-saving processing of the SCell based on the first information.

[0008] Exemplarily, acquiring the first information may also be described as receiving the first information.

[0009] Exemplarily, the state of the SCell not broadcasting in SSB can also be described as the SCell being in the state of not broadcasting in SSB.

[0010] In the above technical solution, after the terminal device obtains the first information indicating that the SCell is not broadcasting in the SSB, it does not perform or stop any measurement and / or data transmission of the SCell, which saves the energy consumption of the terminal device and is conducive to reducing network energy consumption.

[0011] In combination with the first aspect, in some possible implementations of the first aspect, when the SCell is in a state where the SSB is not broadcast, the SCell does not send the SSB.

[0012] Exemplarily, the SCell not sending the SSB may also be described as the SCell stopping sending the SSB.

[0013] It is understandable that when the SCell does not send the SSB, the network device is in a dormant state, which can achieve system energy saving of the network device on the SCell.

[0014] In combination with the first aspect, in some possible implementations of the first aspect, the energy-saving processing of the SCell includes at least one of the following processing methods: if the SCell layer 3 radio resource management (RRM) measurement is configured, the SCell layer 3 RRM measurement is not performed or stopped; if the SCell beam failure detection is configured, the SCell beam failure detection (BFD) measurement is not performed or stopped; or, if the SCell channel state information reporting is configured, the SCell channel state information (CSI) detection and reporting is not performed or stopped.

[0015] Illustratively, layer 3 may also be described as L3, and may also be described as an RRC layer.

[0016] Optionally, SCell layer 3 RRM measurement, SCell BFD, and SCell CSI reporting are configured through an RRC reconfiguration message.

[0017] Exemplarily, the RRC reconfiguration message may also be described as RRC reconfiguration information.

[0018] For example, when the SCell is in the initial state where the SSB is not broadcast, if the SCell layer 3RRM measurement is configured, the SCell layer 3RRM measurement is not performed; if the SCell's BFD is configured, the SCell's BFD measurement is not performed; or if the SCell's CSI reporting is configured, the SCell's CSI detection and reporting are not performed.

[0019] For example, when the state of SCell not broadcasting in SSB is not the initial state, that is, when the state of SCell broadcasting in SSB is converted to the state of SCell not broadcasting in SSB, if SCell layer 3RRM measurement is configured, SCell layer 3RRM measurement is stopped or suspended; if BFD of SCell is configured, BFD measurement of SCell is stopped or suspended; or, if CSI reporting of SCell is configured, CSI detection and reporting of SCell is stopped or suspended.

[0020] In the above technical solution, when the SCellSSB is not broadcasting, the terminal device will not perform relevant measurements, saving the energy consumption of the terminal device. At the same time, the terminal device will not report unnecessary service cell measurement results.

[0021] In combination with the first aspect, in some possible implementations of the first aspect, the first information indicates that the SCell is deactivated and the SCell is not broadcast in the SSB.

[0022] Exemplarily, when the SCell is deactivated and the SCell is in a state where the SSB is not broadcast, the deactivation of the SCell and the state where the SCell is in a state where the SSB is not broadcast can be carried and indicated in the same signaling to save resources.

[0023] In combination with the first aspect, in some possible implementations of the first aspect, the method further includes: obtaining second information, where the second information is used to indicate the status of the SCell in the SSB broadcast.

[0024] In the above technical solution, after obtaining the second information indicating the status of the SCell in the SSB broadcast, the terminal device performs measurement and / or data transmission of the SCell to improve the user experience.

[0025] In combination with the first aspect, in some possible implementations of the first aspect, the SCell is in the SSB broadcast state, and the SCell sends the SSB.

[0026] In combination with the first aspect, in some possible implementations of the first aspect, the second information is used to indicate the state in which the SCell is deactivated and the SCell is broadcast in the SSB, or the second information indicates the state in which the SCell is activated and the SCell is broadcast in the SSB.

[0027] Exemplarily, when the SCell is deactivated and in the SSB broadcast state, the deactivation of the SCell and the SSB broadcast state of the SCell can be carried and indicated in the same signaling to save resources;

[0028] Or when the SCell is activated and in the SSB broadcast state, the SCell activation and the SCell SSB broadcast state can be indicated in the same signaling to save resources.

[0029] In combination with the first aspect, in some possible implementations of the first aspect, the first information is carried in at least one of the following signalings: RRC signaling, or media access control control element (MAC CE) signaling, or downlink control information (DCI) signaling.

[0030] In combination with the first aspect, in some possible implementations of the first aspect, the second information is carried in at least one of the following signaling: RRC signaling, or MAC CE signaling, or DCI signaling.

[0031] Exemplarily, the RRC signaling includes an RRC reconfiguration message, and the DCI signaling includes layer 1 signaling.

[0032] Illustratively, layer 1 may also be described as L1, or as a physical layer.

[0033] In combination with the first aspect, in some possible implementations of the first aspect, the first information and the second information are carried in the same signaling, and the signaling includes at least one of the following: RRC signaling, or MAC CE signaling, or DCI signaling.

[0034] In the above technical solution, when the first information and the second information are carried in the same signaling, resources can be saved.

[0035] In combination with the first aspect, in some possible implementations of the first aspect, if the first information is carried in RRC signaling, the first information is indicated when adding an SCell, or switching, or RRC connection recovery.

[0036] It can be understood that when the first information indicates adding an SCell, or switching, or restoring the RRC connection, the state of the SCell indicated by the first information when the SSB is not broadcast may be the initial state of the SCell.

[0037] Exemplarily, the switching may also be described as a network device switching, which is applicable to scenarios where the network device has dual connections or multiple connections.

[0038] In combination with the first aspect, in some possible implementations of the first aspect, the second information is also used to indicate SSB broadcast information, and the method also includes: searching for SSB based on the second information, and performing at least one of the following operations: layer 3 RRM measurement of SCell; BFD measurement of SCell; or CSI detection and reporting of SCell.

[0039] In the above technical solution, the terminal device can more quickly learn the SSB broadcast period and beam broadcast status according to the SSB broadcast information indicated by the second information, and quickly transmit data, thereby improving the performance of the terminal device.

[0041] In combination with the first aspect, in some possible implementations of the first aspect, the SSB broadcast information includes at least one of the following information: an SSB broadcast period, a time domain position of the SSB, an SSB broadcast period identifier, or an SSB broadcast information identifier.

[0043] In combination with the first aspect, in some possible implementations of the first aspect, the mapping relationship between the SSB broadcast cycle identifier and the SSB broadcast cycle is carried in the RRC reconfiguration message;

[0044] Alternatively, the mapping relationship between the SSB broadcast information identifier and the SSB broadcast period and the time domain position of the SSB is carried in the RRC reconfiguration message.

[0045] In combination with the first aspect, in some possible implementations of the first aspect, obtaining the second information includes: obtaining the second information in response to sending an uplink random access sequence, where the uplink random access sequence is used to request the second information.

[0046] Exemplarily, responding to sending an uplink random access sequence may also be described as responding to sending a scheduling request.

[0047] Optionally, the MAC CE signaling carrying the second information includes random access response signaling.

[0048] In the above technical solution, when SCellSSB is not broadcasting, the terminal device can actively send an uplink random access sequence to the network device according to its own business volume requirements to obtain the second information indicating the status of SCell in SSB broadcasting, so that the terminal device can quickly detect the SSB signal, thereby achieving energy saving and improving user experience.

[0049] In combination with the first aspect, in some possible implementations of the first aspect, the method also includes: obtaining third information, where the third information is used to configure random access channel (RACH) parameters on the SCell, where the RACH includes a mapping relationship between RACH resources and SSB broadcast periods.

[0050] Exemplarily, the third information is carried in an RRC reconfiguration message.

[0051] In the above technical solution, based on the mapping relationship between RACH resources and SSB broadcast period, the SSB broadcast period can be quickly determined to improve user experience.

[0052] On the second aspect, the present application provides an energy-saving method, which can be executed by a network device, or by a component configured in the network device (such as a chip, a chip system, etc.), or by a logic module or software that can realize all or part of the network device functions. The present application does not limit this.

[0053] Optionally, the method includes: sending first information, where the first information is used to indicate that the SCell is not broadcasting in the SSB.

[0054] In the above technical solution, when the SCell is in the SSB non-broadcasting state, the network device is in a dormant state, thereby achieving system energy saving of the network device on the SCell.

[0055] In combination with the second aspect, in some possible implementations of the second aspect, when the SCell is in a state where the SSB is not broadcast, the SCell does not send the SSB.

[0056] In combination with the second aspect, in some possible implementations of the second aspect, the first information is used to indicate a state in which the SCell is deactivated and the SCell is not broadcast in the SSB.

[0057] In combination with the second aspect, in some possible implementations of the second aspect, the method further includes: sending second information, where the second information is used to indicate the status of the SCell in the SSB broadcast.

[0107] The technical solution in this application will be described below with reference to the accompanying drawings.

[0108] The technical solutions provided in this application can be applied to various communication systems, such as long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, fifth generation (5G) mobile communication systems, or new radio access technology (NR). The 5G mobile communication system may include non-standalone (NSA) and / or standalone (SA) networking.

[0109] The technical solution provided in this application can also be applied to machine type communication (MTC), long term evolution-machine (LTE-M), device-to-device (D2D) network, machine-to-machine (M2M) network, Internet of Things (IoT) network or other networks. Among them, the IoT network can include, for example, the Internet of Vehicles. Among them, the communication mode in the Internet of Vehicles system is collectively referred to as vehicle to other devices (vehicle to X, V2X, X can represent anything) system, for example, the V2X can include: vehicle to vehicle (V2V) communication, vehicle to infrastructure (V2I) communication, vehicle to pedestrian (V2P) communication or vehicle to network (V2N) communication, etc.

[0110] The technical solution provided in this application can also be applied to future communication systems, such as the sixth generation (6G) mobile communication system, etc. This application does not limit this.

[0111] Energy consumption has become a significant component of operators' operating expenses (OPEX). According to a report by the Global System for Mobile Communications Association (GSMA), mobile network energy costs account for approximately 23% of operators' total costs. The majority of energy consumption comes from the radio access network, particularly the active antenna unit (AAU), with data centers and fiber optic transmission contributing smaller shares. Radio access power consumption can be divided into two components: dynamic and static. The dynamic component is consumed only when data transmission or reception is in progress, while the static component is consumed continuously to maintain the necessary operations of the radio access equipment, even when data transmission or reception is not in progress. To achieve energy conservation in base stations, current research focuses on technologies in the time, frequency, spatial, and power domains. For example, the main goal of time and frequency domain technologies is to reduce the dynamic power consumption by attempting to shut down multiple SCells on one or more carriers to achieve micro-sleep in the base station. Alternatively, static power consumption can be reduced by increasing the intervals between consecutive active transmission or reception times to achieve light or deep sleep in the base station. The space domain and power domain technologies mainly reduce the power consumption of the carrier frequency chain and power amplifier by trying to shut down more space antennas and / or reduce the transmission power or power spectrum density or improve the power amplifier efficiency.

[0112] In related technologies, high network energy consumption is mainly reflected in the continuous broadcasting of public control signals / channels, such as continuous transmission of SSB. Based on the above problem, the embodiment of the present application proposes an energy-saving method, the main inventive ideas of which are as follows:

[0113] For SCell on-demand SSB broadcast, the network device indicates to the terminal device that the SCell is not broadcasting SSB. The network device does not broadcast SSB on the SCell and enters the energy-saving state, thereby achieving system energy saving of the network device on the SCell. At the same time, the terminal device does not perform service cell measurement, saving energy consumption of the terminal device and helping to reduce network energy consumption.

[0114] In order to better understand the embodiments of the present application, the following first briefly explains the terms involved in the embodiments of the present application.

[0115] 1. Carrier aggregation (CA): This allows a terminal device to use multiple cells (carriers) for uplink and downlink communications simultaneously, thereby supporting high-speed data transmission. Among the multiple cells, one cell is the primary cell (PCell), and the other cells are SCells.

[0116] SCell reconfiguration, addition, and deletion can be performed by RRC. During handover within a new radio (NR) system and during connection recovery from RRC_INACTIVE, network devices can also add, delete, retain, or reconfigure SCells for use with the target PCell. When adding a new SCell, dedicated RRC signaling is used to transmit all system information required by the SCell. This means that when in connected mode, the terminal device does not need to obtain broadcast system information directly from the SCell.

[0117] A newly added SCell is inactive by default. The next generation nodeB (gNodeB) determines when an inactive SCell transitions to active mode. For example, when a terminal device has a high volume of traffic waiting to be transmitted, the gNodeB activates the SCell. Another example is when the gNodeB sets a deactivation timer for each SCell. When each SCell is activated, the deactivation timer starts. If the SCell detects no control or service data within the timer's duration, it automatically deactivates the SCell. Another example is when the gNodeB can configure a newly added SCell to be active.

[0118] 2. Connected state measurement: In a mobile communication system, the network device will issue a measurement configuration. The terminal device will perform measurements based on the measurement configuration and determine whether a measurement report needs to be triggered. If so, the measurement report will be reported to the network device. The network device will perform mobility decisions or carrier management based on the measurement report reported by the terminal device.

[0119] Specifically, the measurement configuration includes the following related parameters:

[0120] 1) Measurement object (measObject): The measurement object is the object on which the terminal device performs measurement, mainly including SSB frequency, SSB subcarrier spacing, measurement timing configuration (SMTC), whitelist cells and blacklist cells;

[0121] 2) Report Configuration (reportConfig): Mainly includes measurement events, measurement report trigger-related configurations, etc. NR measurement reports are based on the results of SSB measurements. Each reporting configuration has a separate identifier (reportConfigId), which is divided into event-triggered reporting and periodic triggering reporting according to type. For example, in the configuration measurement event A3, the service quality of the neighboring cell is higher than the serving cell by an offset value (Neighbour becomes offset better than PCell), and related offset values, etc.

[0122] 3) Measurement Identifier (ID): This corresponds to a measurement object and a report configuration, combining the measurement object and the report configuration to generate a measurement task. The terminal device measures the measurement object associated with the measurement ID according to the report configuration requirements. When the terminal device sends a measurement report to the base station, the terminal device indicates the measurement ID, and the base station can then find the corresponding measurement object and report configuration based on the measurement ID. Typically, the base station configures the A6 measurement event to measure the SCell. After configuring the SCell, the terminal device measures the signal quality of the cell on the same frequency as the SCell. If a cell with better signal quality than the current SCell appears, the terminal device replaces the current SCell with the cell with better signal quality, first deleting the original SCell and then configuring the same-frequency cell with better signal quality as the new SCell. The base station can also configure the A2 measurement event to measure the SCell, and the terminal device will periodically measure the signal quality of the SCell. If the signal quality falls below a specific threshold, the SCell is deleted.

[0123] 3. Beam failure detection: For beam failure detection, the gNB configures a beam failure detection reference signal (SSB or channel-state information reference signal (CSI-RS)) to the terminal device. When the number of beam failure instances indicated by the physical layer reaches a configured threshold before the configured timer expires, the terminal device declares beam failure. After detecting beam failure on an SCell, the UE triggers beam failure recovery by initiating the transmission of a beam failure recovery (BFR) MAC CE for that SCell. It selects an appropriate beam for that SCell (if available) and indicates the beam and beam failure related information in the BFR MAC CE.

[0124] The network device can configure the following parameters to the terminal device through the RRC reconfiguration message for the SCell beam failure detection and recovery process: beamFailureInstanceMaxCount (per serving cell) for beam failure detection and beamFailureDetectionTimer (per serving cell) for beam failure detection. Specifically: beamFailureDetectionTimer: timer for beam failure detection. "Qout, link recovery (LR) reporting period for beam failure detection" number of reference signals. beamFailureInstanceMaxCount: This field determines how many beam failure events the UE triggers beam failure recovery. Exemplarily, the value n1 corresponds to 1 beam failure instance, the value n2 corresponds to 2 beam failure instances, and so on.

[0125] The energy-saving method provided by this application will be described in detail below with reference to the accompanying drawings.

[0126] For ease of understanding, the following points are first explained:

[0127] First, in this application, indications include explicit indications (also called direct indications) and implicit indications (also called indirect indications). Specifically, explicit indication information A refers to including information A; implicit indication information A refers to indicating information A through the correspondence between information A and information B and directly indicating information B. The correspondence between information A and information B can be predefined, pre-stored, pre-burned, or pre-configured; or, it can also refer to indicating information A through information B and preset rules.

[0128] Second, in this application, "at least one" means one or more, and "more" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship, but it does not exclude the situation where it indicates that the previous and next associated objects are in an "and" relationship. The specific meaning can be understood in conjunction with the context. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b, or c can mean: a, b, c; a and b; a and c; b and c; or a and b and c. Where a, b, c can be single or multiple.

[0129] Third, in this application, prefixes such as "first" and "second" are used solely to distinguish between different items belonging to the same category and do not constrain the order, size, or quantity of the items. For example, "first information" and "second information" are simply different pieces of information; there is no temporal, size, or priority relationship between them.

[0130] Fourth, the "sending" and "receiving" in this application indicate the direction of signal transmission. For example, "sending information to the terminal" can be understood as the destination end of the information is the terminal, which can include direct sending through the air interface, and also include indirect sending through the air interface by other units or modules. "Receiving information from a network device" can be understood as the source end of the information is the network device, which can include direct receiving from the network device through the air interface, and also include indirect receiving from the network device through the air interface from other units or modules. "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.

[0131] In other words, sending and receiving can be performed between devices, for example, between a terminal and a network device; or it can be performed within a device, for example, sending or receiving between components, modules, chips, software modules or hardware modules within the device through a bus, wiring or interface.

[0132] Fifth, in the embodiments of the present application, "when", "if" and "if" all mean that the device will perform corresponding processing under certain objective circumstances, which does not limit the time, nor does it require that the device must perform a judgment action when it is implemented, nor does it mean that there are other limitations.

[0133] Sixth, in this application, words such as "example," "exemplarily," "for example," or "such as" are used to indicate examples, illustrations, or explanations. Any embodiment or design described in this application as "example," "exemplarily," "for example," or "such as" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "example," "exemplarily," "for example," or "such as" is intended to present the relevant concepts in a concrete manner.

[0134] The communication system provided in the embodiments of the present application will be described in detail below.

[0135] FIG1 is a schematic diagram of the architecture of a communication system applicable to the energy-saving method provided in this application.

As shown in FIG1 , the communication system 10 includes a terminal device 101 and a network device 102, and the terminal device 101 and the network device 102 are in wireless communication.

[0142] The technical solutions shown in this application are described in detail below through specific embodiments. It should be noted that the following embodiments can exist independently or in combination with each other. For the same or similar content, such as the explanation of terms or nouns, and the explanation of steps, etc., different embodiments can refer to each other and will not be repeated.

[0143] FIG2 is a schematic flow chart of an energy-saving method provided in an embodiment of the present application. As shown in FIG2 , the energy-saving method provided in an embodiment of the present application includes the following steps:

[0144] S201, the network device sends the first information, and accordingly, the terminal device obtains the first information, where the first information is used to indicate the state of the SCell not broadcasting in the SSB.

[0145] It is understandable that before sending the first information, the network device needs to determine the first information first.

[0146] Optionally, the network device determines the first information when detecting that energy saving is required.

[0147] Specifically, when the network device detects that the load is small or the number of connected terminal devices is small, it determines the first information, that is, the network device decides to turn off the SSB of any SCell, so that the SSB of the SCell enters a non-broadcast state.

[0148] Exemplarily, sending the first information may also be described as indicating the first information or transmitting the first information; obtaining the first information may also be described as receiving the first information.

[0149] Specifically, it can be described as the terminal device obtaining the first information sent by the network device, or the terminal device receiving the first information sent by the network device, or the terminal device obtaining the first information indicated by the network device, or the terminal device receiving the first information indicated by the network device, or the terminal device obtaining the first information transmitted by the network device, or the terminal device receiving the first information transmitted by the network device.

[0150] Exemplarily, the state of the SCell not broadcasting in SSB can also be described as the SCell being in the state of not broadcasting in SSB.

[0151] Optionally, when the SCell is in a state where the SSB is not broadcast, the SCell does not send the SSB.

[0152] Exemplarily, the SCell not sending the SSB may also be described as the SCell stopping sending the SSB.

[0153] For example, the state in which SSB is not broadcast may be represented as SSB-less or non-SSB.

[0154] Exemplarily, the state in which the SCell is not broadcasting in SSB can be expressed as SCell is in SSB-less state or SCell is in non-SSB state.

[0155] Exemplarily, the SCell not sending SSB can also be described as the SCell not sending SSB in the initial state.

[0156] Exemplarily, the state in which SSB is not broadcast may be that the SCell is deactivated and the SSB is not broadcast on the SCell.

[0157] Exemplarily, the state in which SSB is not broadcast may also be that the SCell is activated and the SSB is not broadcast on the SCell.

[0158] Optionally, the first information is used to indicate that the SCell is deactivated and is not broadcast in the SSB.

[0159] Optionally, the first information is also used to indicate a state in which the SCell is activated and the SCell is not broadcast in the SSB.

[0160] Optionally, the first information is carried in at least one of RRC signaling, MAC CE signaling, or DCI signaling.

[0161] It can be understood that the first information can be carried in any one of the above signalings, or can be carried in at least two signalings at the same time.

[0162] Exemplarily, when the SCell is deactivated and the SCell is in a state where the SSB is not broadcast, the deactivation of the SCell and the state where the SCell is in a state where the SSB is not broadcast can be carried in the same signaling to save resources; or they can be indicated in different signalings.

[0163] Exemplarily, when the SCell is activated and the SCell is in a state where the SSB is not broadcast, the activation of the SCell and the state where the SCell is in a state where the SSB is not broadcast can be carried and indicated in the same signaling to save resources; or they can be indicated in different signalings.

[0164] It is understandable that the information indicating the activation or deactivation of the SCell and the information indicating the state of the SSB broadcast or the state of the SSB non-broadcast can be carried in the same signaling or in different signaling. In the embodiments of the present application, all examples are explained by carrying the information indicating the activation or deactivation of the SCell and the information indicating the state of the SSB broadcast or the state of the SSB non-broadcast in the same signaling.

[0165] It should be noted that the energy-saving method provided in the embodiment of the present application does not limit the activation state and deactivation state of the SCell. It is only necessary to set the SSB state of the SCell according to the needs.

[0166] Exemplarily, the state of the SCell in which the SSB is not broadcast may be the initial state of the SCell, or may be obtained by updating the state of the SCell SSB, that is, updating the state of the SCell SSB broadcast to the state of the SCell SSB non-broadcast.

[0167] The state of the SCell SSB broadcast may be a state in which the SCell is activated and the SSB is broadcast, or a state in which the SCell is deactivated and the SSB is broadcast.

[0168] Optionally, if the first information is carried in RRC signaling and the first information is sent when a new SCell is added, the network device is switched, and the RRC connection is restored, the state of the SCell indicated by the first information when the SSB is not broadcast can be the initial state of the SCell SSB, and correspondingly, the SCell can be in a deactivated state.

[0169] S202: The terminal device performs energy-saving processing of the SCell according to the first information.

[0170] Specifically, after receiving the first information sent by the network device to indicate that the SCell is not broadcasting in the SSB, the terminal device will not perform or stop or suspend measurement of the serving cell, i.e., the SCell, or will not perform or stop or suspend reporting of measurement results of the serving cell, i.e., the SCell.

[0171] Exemplarily, after the terminal device receives the first information sent by the network device to indicate that the SCell is not broadcasting in the SSB, the terminal device will not perform, stop or suspend measurement of the serving cell measurement object (ServingCellMO), or report the measurement results.

[0172] Optionally, the energy-saving processing method of SCell may include one or more of the following: if SCell layer 3RRM measurement is configured, SCell layer 3RRM measurement or measurement result reporting is not performed or stopped; if SCell's BFD is configured, SCell's BFD measurement is not performed or stopped; or if SCell's CSI reporting is configured, SCell's CSI detection and reporting is not performed or stopped.

[0173] Exemplarily, CSI reporting includes periodic reporting, semi-persistent reporting, or aperiodic reporting.

[0174] Illustratively, layer 3 may also be described as L3, and may also be described as an RRC layer.

[0175] Optionally, the energy-saving processing method of SCell can also be one or more of the following: if SCell layer 3RRM measurement is configured, SCell layer 3RRM measurement or measurement result reporting is suspended; if SCell BFD is configured, SCell BFD measurement is suspended; or if SCell CSI reporting is configured, SCell CSI detection and reporting are suspended.

[0176] It should be noted that if the state of the SCell not broadcasting in the SSB indicated by the first information is the initial state of the SCell SSB, it means that the terminal device has not yet performed the configured service cell measurement, and the terminal device does not perform the corresponding measurement of the configured service cell after obtaining the first information sent by the network device; if the state of the SCell not broadcasting in the SSB indicated by the first information is not the initial state of the SCell SSB, it means that the terminal device is performing the configured service cell measurement, and the terminal device stops or suspends the corresponding measurement of the configured service cell after obtaining the first information sent by the network device.

[0177] Specifically, stop means not saving the current measurement data or measurement results, and subsequently restarting the measurement of the serving cell according to the obtained indication information; pause means retaining the current measurement data or measurement results, and subsequently continuing the measurement of the serving cell according to the obtained indication information.

[0178] In an embodiment of the present application, after the terminal device obtains the first information sent by the network device to indicate that the SCell is not broadcasting in the SSB, the terminal device does not perform or stop any measurement and / or data transmission of the SCell, which saves energy consumption of the terminal device and is beneficial to reducing network energy consumption. At the same time, when the SCell is not broadcasting in the SSB, the network device is in a sleep state, thereby realizing system energy saving of the network device on the SCell.

[0179] The following describes in detail the implementation of the energy saving method in which the first information is carried in the RRC signaling with reference to FIG3 .

[0180] FIG3 is a schematic flow chart of an energy-saving method provided by another embodiment of the present application. As shown in FIG3 , the energy-saving method includes the following steps:

[0181] S301, the network device sends the first information, and accordingly, the terminal device obtains the first information, which is used to indicate the state of the SCell not broadcasting in the SSB.

[0182] Exemplarily, sending the first information may also be described as indicating the first information or transmitting the first information, and obtaining the first information may also be described as receiving the first information.

[0183] Exemplarily, the network device may send the first information via the SCell, or may send the first information via the PCell or other SCells. In the embodiment of the present application, there is no limitation on the number of SCells, and the specific number of SCells is determined according to actual needs.

[0184] Exemplarily, the network device sends the first information after stopping the SSB broadcast on the SCell; or stops the SSB broadcast on the SCell after sending the first information.

[0185] It should be noted that the energy-saving method provided in the embodiment of the present application does not limit the order in which the network device stops the SSB broadcast on the SCell and sends the first information.

[0186] Optionally, the state of the SCell not broadcasting in SSB may also be described as the SCell being in the state of not broadcasting in SSB.

[0187] Optionally, when the SCell is in a state where the SSB is not broadcast, the SCell does not send the SSB, or it can also be described as the SCell stops sending the SSB.

[0188] Exemplarily, the state of the SCell when the SSB is not broadcasting may be that the SCell is deactivated and the SSB is not broadcasting.

[0189] Exemplarily, the state of SCell in which SSB is not broadcast may also be that SCell is activated and SSB is not broadcast.

[0190] Optionally, the first information is used to indicate that the SCell is deactivated and is not broadcast in the SSB.

[0191] Optionally, the first information is also used to indicate a state in which the SCell is activated and the SCell is not broadcast in the SSB.

[0192] Optionally, the first information is carried in RRC signaling.

[0193] Optionally, the RRC signaling includes an RRC reconfiguration message.

[0194] Exemplarily, the RRC reconfiguration message may also be described as RRC reconfiguration information.

[0195] Specifically, the network device indicates to the terminal device in the RRC reconfiguration message that the SCell is not broadcast in the SSB.

[0196] Optionally, the SSB non-broadcast state may be an initial state, or may be updated from the SSB broadcast state to the SSB non-broadcast state.

[0197] Exemplarily, the SCell not sending SSB can also be described as the SCell not sending SSB in the initial state.

[0198] In one possible implementation, the first information indicated by the network device when adding an SCell, or switching, or restoring the RRC connection, the corresponding SSB non-broadcast state can be an initial state, wherein the switching can be the switching of the terminal device.

[0199] In another possible implementation, the network device may update the SSB state through an RRC reconfiguration message, that is, by indicating the first information to the terminal device, the SSB of the SCell is updated from the SSB broadcast state to the SSB non-broadcast state.

[0200] Exemplarily, the indication of the SCell SSB state in the RRC reconfiguration message may include at least one of the following implementations:

[0201] Method 1:

[0202] SCellConfig::= SEQUENCE{

[0203] SCellIndex SCellIndex,

[0204] SCellNoSSBstate ENUMERATED{true}optional}

[0205] Among them, SEQUENCE{…} means that all the parameters enumerated later can be included, and ENUMERATED{…} means taking one of the parameters enumerated later.

[0206] Specifically, when the parameter in SEQUENCE{…} includes SCellNoSSBstate and the parameter in ENUMERATED{…} is true, it indicates that the indication of the SCell SSB state in the RRC reconfiguration message is a state in which the SCell is not broadcast in the SSB.

[0207] Method 2:

[0208] Among them, SEQUENCE{…} means that all the parameters enumerated later can be included, and ENUMERATED{…} means taking one of the parameters enumerated later.

[0209] Specifically, when the parameters in SEQUENCE{…} include SCellSSBstate and the parameter in ENUMERATED{…} is broadcast, it indicates that the indication of the SCell SSB state in the RRC reconfiguration message is the state of SCell broadcast in SSB; when the parameter in ENUMERATED{…} is not broadcast, it indicates that the indication of the SCell SSB state in the RRC reconfiguration message is the state of SCell not broadcast in SSB.

[0210] Method 3:

[0211] SCellConfig::= SEQUENCE{

[0212] SCellIndex SCellIndex,

[0213] SCellwithSSBstate ENUMERATED{true}optional}

[0214] Among them, SEQUENCE{…} means that all the parameters enumerated later can be included, and ENUMERATED{…} means taking one of the parameters enumerated later.

[0215] Specifically, when the parameter in SEQUENCE{…} includes SCellwithSSBstate and the parameter in ENUMERATED{…} is true, it indicates that the indication of the SCell SSB state in the RRC reconfiguration message is the state of the SCell broadcast in SSB.

[0216] It can be understood that the above implementation methods are only some examples, and the energy-saving method provided in the embodiments of the present application does not limit the implementation method of indicating the SCell in the SSB non-broadcast state through RRC signaling.

[0217] It is understandable that the above RRC signaling can also indicate the status of SCell in SSB broadcast.

[0218] Optionally, the first information and the second information can be carried in the same RRC signaling to indicate the state of the SCell not broadcasting in the SSB and / or the state of the SCell broadcasting in the SSB.

[0219] S302: If SCell layer 3 RRM measurement is configured, SCell layer 3 RRM measurement or measurement result reporting is not performed or stopped; if SCell BFD is configured, SCell BFD measurement is not performed or stopped; or, if SCell CSI reporting is configured, SCell CSI detection and reporting is not performed or stopped.

[0220] Exemplarily, CSI reporting includes periodic reporting, semi-persistent reporting, or aperiodic reporting.

[0221] It is understandable that when the network device indicates to the terminal device that the SCell is not broadcasting in the SSB, the terminal device will not perform measurements on the serving cell, i.e., the SCell, or will not execute, stop, or suspend reporting of measurement results on the serving cell, i.e., the SCell.

[0222] Exemplarily, after the terminal device receives the first information sent by the network device to indicate that the SCell is not broadcasting in the SSB, the terminal device will not perform, stop or suspend measurement of the serving cell measurement object (ServingCellMO), or report the measurement results.

[0223] Specifically, the measurement of the serving cell may be determined according to measurement parameters pre-configured for the serving cell.

[0224] For example, when the RRC signaling indicates that the SCell is in the initial state when the SSB is not broadcast, if the SCell layer 3RRM measurement is configured, the SCell layer 3RRM measurement or measurement result reporting is not performed; if the BFD of the SCell is configured, the BFD measurement of the SCell is not performed; or if the CSI reporting of the SCell is configured, the CSI detection and reporting of the SCell are not performed.

[0225] For example, when the RRC signaling indicates that the SCell is updated from the SSB broadcast state to the SSB non-broadcast state, if the SCell layer 3 RRM measurement is configured, the SCell layer 3 RRM measurement or measurement result reporting is stopped or suspended; if the BFD of the SCell is configured, the BFD measurement of the SCell is stopped or suspended; or if the CSI reporting of the SCell is configured, the CSI detection and reporting of the SCell is stopped or suspended.

[0226] Specifically, the meanings of stop and pause are similar to those described above and will not be repeated here.

[0227] S303, the terminal device sends an RRC reconfiguration completion message, and accordingly, the network device receives the RRC reconfiguration completion message.

[0228] Specifically, the terminal device sending the RRC reconfiguration completion message may be that the terminal device sends the RRC reconfiguration completion message to the network device after completing corresponding operations according to the RRC reconfiguration message.

[0229] Exemplarily, the RRC reconfiguration complete message may be expressed as RRCReconfigurationcomplete.

[0230] In an embodiment of the present application, the network device sends first information to the terminal device through RRC signaling to indicate the state of the SCell not broadcasting in the SSB. After the terminal device obtains the first information, when the layer 3 RRM measurement or beam detection measurement or L1 measurement of the SCell is configured, the terminal device will not perform relevant measurements of the service cell when the SCell is not broadcasting in the SSB. At the same time, the terminal device will not report unnecessary service cell measurement results, which saves energy consumption of the terminal device and is conducive to reducing network energy consumption.

[0231] The following describes in detail the implementation of the energy saving method in which the first information is carried in MAC CE signaling or DCI signaling in conjunction with FIG. 4 .

[0232] FIG4 is a schematic flow chart of an energy-saving method provided in another embodiment of the present application. As shown in FIG4 , the energy-saving method includes the following steps:

[0233] S401: The network device decides that the SCell stops SSB broadcasting or decides that the SCell is in a non-SSB broadcasting state.

[0234] It is understandable that after the network device turns on the SCell SSB and serves the terminal device for a period of time, it will stop SSB broadcasting or not send SSB, thus entering an energy-saving state.

[0235] Exemplarily, the network device enabling SCell SSB includes activating SCell and SSB broadcasting, and deactivating SCell and SSB broadcasting.

[0236] S402, the network device sends the first information, and accordingly, the terminal device obtains the first information, where the first information is used to indicate the state of the SCell not broadcasting in the SSB.

[0237] Exemplarily, sending the first information may also be described as indicating the first information or transmitting the first information, and obtaining the first information may also be described as receiving the first information.

[0238] Exemplarily, the network device sends the first information through the SCell, and may also send the first information through the PCell or other SCells.

[0239] Exemplarily, the network device sends the first information after stopping the SSB broadcast on the SCell; or stops the SSB broadcast on the SCell after sending the first information.

[0240] It should be noted that the energy-saving method provided in the embodiment of the present application does not limit the order in which the network device stops the SSB broadcast on the SCell and sends the first information.

[0241] Optionally, the state of the SCell not broadcasting in SSB may also be described as the SCell being in the state of not broadcasting in SSB.

[0242] Optionally, when the SCell is in a state where the SSB is not broadcast, the SCell does not send the SSB.

[0243] Exemplarily, the state of the SCell when the SSB is not broadcasting may be that the SCell is deactivated and the SSB is not broadcasting.

[0244] Exemplarily, the state of SCell in which SSB is not broadcast may also be that SCell is activated and SSB is not broadcast.

[0245] Optionally, the first information is used to indicate that the SCell is deactivated and is not broadcast in the SSB.

[0246] Optionally, the first information is also used to indicate a state in which the SCell is activated and the SCell is not broadcast in the SSB.

[0247] Optionally, the first information is carried in MAC CE signaling or DCI signaling.

[0248] Optionally, the DCI signaling includes layer 1 signaling.

[0249] Illustratively, layer 1 may also be described as L1, or as a physical layer.

[0250] The following first describes in detail the case where the first information is carried in the MAC CE signaling with reference to FIG. 5 to FIG. 9 .

[0251] Optionally, in the MAC CE signaling, the MAC subheader includes a logical channel ID, which is used to indicate that the MAC control command is an SCell SSB stop command.

[0252] It can be understood that the SCell SSB stop command means that the SCell SSB is not broadcast.

[0253] For example, the SCell SSB not being broadcast can also be described as the SCell not sending SSB.

[0254] Specifically, the specific expression manner of the MAC CE signaling may include one or more.

[0255] First, one or more ways of expressing that MAC CE signaling indicates only a single serving cell are described:

[0256] Method 1:

[0257] Figure 5 is a schematic diagram of a MAC CE signaling provided in an embodiment of the present application. As shown in Figure 5, the MAC CE signaling includes a redundant bit R and a serving cell identification field.

[0258] Exemplarily, the value of the redundancy bit R may be 0.

[0259] Exemplarily, the serving cell identification field may be expressed as Serving Cell ID or SCellIndex.

[0260] Specifically, the serving cell identifier field is used to indicate the identifier or index of the serving cell indicated by the MAC CE signaling.

[0261] Exemplarily, the serving cell identification field may be 5 bits long.

[0262] It is understandable that the network device sends the first information indicating the non-broadcast state of the SCell in the SSB to the terminal device through MAC CE signaling, so that the terminal device performs energy-saving processing on the serving cell according to the identifier or index of the serving cell indicated by the MAC CE signaling. Specifically, the energy-saving processing method is similar to the above and will not be repeated here.

[0263] It should be noted that the energy-saving method provided in the embodiment of the present application does not limit the length of the serving cell identification field in the MAC CE signaling, and the specific length can be determined according to actual needs.

[0264] Method 2:

[0265] Figure 6 is a schematic diagram of another MAC CE signaling provided in an embodiment of the present application. As shown in Figure 6, the MAC CE signaling includes a redundancy bit R, a serving cell identification field, and an SSB status indication field.

[0266] Exemplarily, the value of the redundancy bit R may be 0.

[0267] Exemplarily, the serving cell identification field may be expressed as Serving Cell ID or SCellIndex.

[0268] Exemplarily, the SSB status indication field includes an SSB non-broadcast status indication field and / or an SSB broadcast status indication field.

[0269] Exemplarily, the SSB status indication field can be expressed as SSBstate indicator, the SSB non-broadcast status indication field can be expressed as SSB-less indicator, and the SSB broadcast status indication field can be expressed as SSBindicator.

[0270] Specifically, the serving cell identifier field is used to indicate the identifier or index of the serving cell indicated by the MAC CE signaling.

[0271] Exemplarily, the serving cell identification field may be 5 bits long.

[0272] Optionally, the SSB status indication field in the MAC CE signaling shown in Figure 6 is used to indicate whether the SCell is in a deactivated state and SSB is not broadcast, or a deactivated state and SSB is broadcast, or a activated state and SSB is not broadcast, or a activated state and SSB is broadcast.

[0273] It should be noted that the SSB status indication field in the MAC CE signaling uses a single bit to indicate whether the SCell is in the SSB non-broadcast state or the SSB broadcast state.

[0274] Specifically, when the bit value corresponding to the SSB status indication field is 1, it indicates that the SCell broadcasts SSB; when the bit value corresponding to the cell SSB status indication field is 0, it indicates that the SCell does not broadcast SSB.

[0275] Correspondingly, when the bit value corresponding to the SSB status indication field is 0, it indicates that the SCell broadcasts SSB; when the bit value corresponding to the cell SSB status indication field is 1, it indicates that the SCell does not broadcast SSB.

[0276] Optionally, the state of SCell in which SSB is not broadcast can be deactivating SCell and not broadcasting SSB, or activating SCell and not broadcasting SSB; the state of SCell in which SSB is broadcasting can be deactivating SCell and broadcasting SSB, or activating SCell and broadcasting SSB.

[0277] Specifically, when the bit corresponding to the SSB status indication field is 0, it indicates that the SCell is in a deactivated and SSB broadcasting state or an activated and SSB broadcasting state, that is, the SCell is deactivated or activated, and in this state, the network device continues to broadcast SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit corresponding to the SSB status indication field is 1, it indicates that the SCell is in a deactivated and SSB not broadcasting state or an activated and SSB not broadcasting state, that is, the SCell is deactivated or activated, and in this state, the network device stops broadcasting SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement.

[0291] Correspondingly, when the bit value corresponding to the SSB status indication field is 01, it indicates that the SCell is in a deactivated and SSB broadcast state, that is, the SCell is deactivated, and in this state, the network device continues to broadcast SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit value corresponding to the SSB non-broadcast status indication field is 10, it indicates that the SCell is in a deactivated and SSB non-broadcast state, that is, the SCell is deactivated, and in this state, the network device stops broadcasting SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement; when the bit value corresponding to the SSB status indication field is 11, it indicates that the SCell is in an activated and SSB broadcast state, that is, the SCell is activated, and in this state, the network device continues to broadcast SSB on the SCell, and the terminal device performs service cell measurement; when the bit value corresponding to the SSB status indication field is 00, it indicates that the SCell is in an activated and SSB non-broadcast state, that is, the SCell is activated, and in this state, the network device does not broadcast SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement.

[0292] Correspondingly, when the bit corresponding to the SSB status indication field is 10, it indicates that the SCell is in a deactivated and SSB broadcast state, that is, the SCell is deactivated, and in this state, the network device continues to broadcast SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit corresponding to the SSB status indication field is 11, it indicates that the SCell is deactivated and SSB is not broadcast, that is, the SCell is deactivated, and in this state, the network device stops broadcasting SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement; when the bit corresponding to the SSB status indication field is 00, it indicates that the SCell is activated and SSB is broadcast, that is, the SCell is activated, and in this state, the network device continues to broadcast SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit corresponding to the SSB status indication field is 01, it indicates that the SCell is activated and SSB is not broadcast, that is, the SCell is activated, and in this state, the network device does not broadcast SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement.

[0293] Accordingly, when the bit corresponding to the SSB status indication field is 11, it indicates that the SCell is in a deactivated and SSB broadcast state, that is, the SCell is deactivated, and in this state, the network device continues to broadcast SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit corresponding to the SSB status indication field is 00, it indicates that the SCell is deactivated and SSB is not broadcast, that is, the SCell is deactivated, and in this state, the network device stops broadcasting SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement; when the bit corresponding to the SSB status indication field is 01, it indicates that the SCell is activated and SSB broadcast, that is, the SCell is activated, and in this state, the network device continues to broadcast SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit corresponding to the SSB status indication field is 10, it indicates that the SCell is activated and SSB is not broadcast, that is, the SCell is activated, and in this state, the network device does not broadcast SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement.

[0294] Exemplarily, continuing to broadcast SSB on the SCell can also be described as continuing to send SSB on the SCell, and correspondingly, stopping broadcasting SSB on the SCell can also be described as stopping sending SSB on the SCell.

[0295] The following describes one or more ways of expressing MAC CE signaling to indicate multiple serving cells at the same time:

[0296] Method 1:

[0297] Figure 8 is a schematic diagram of another MAC CE signaling provided in an embodiment of the present application. As shown in Figure 8, the MAC CE signaling includes a redundant bit R and a Ci field.

[0298] Exemplarily, the value of the redundancy bit R may be 0.

[0299] Optionally, the Ci field is used to indicate the state of the SSB of the SCell with the SCell index SCellIndex being i.

[0300] It should be noted that the SSB status indication field in the MAC CE signaling uses a single bit to indicate the status of the SSB of the SCell with the SCell index SCellIndex being i.

[0301] Specifically, when Ci is set to 1, it means that the SCell with SCellIndex i is deactivated and SSB is broadcast, or it means that the SCell with SCellIndex i is activated and SSB is broadcast; when Ci is set to 0, it means that the SCell with SCellIndex i is deactivated and SSB is not broadcast, or it means that the SCell with SCellIndex i is activated and SSB is not broadcast.

[0310] Exemplarily, the SSB status indication field of multiple service cells can be expressed as SSBstate indicator, the SSB non-broadcast status indication field can be expressed as SSB-less indicator, and the SSB broadcast status indication field can be expressed as SSB indicator.

[0311] Optionally, the SSB status indication field of multiple serving cells is used to indicate the status of the SSB of the SCell with the SCell index SCellIndex being i.

[0312] It should be noted that the SSB status indication field of multiple SCells in the MAC CE signaling uses two bits to indicate the status of the SSB of the SCell with the SCell index SCellIndex being i.

[0314] Correspondingly, when the bit value corresponding to the SSB status indication field is 01, it indicates that the SCell with SCellIndex i is in a deactivated and SSB broadcasting state, that is, the SCell is deactivated, and in this state, the network device continues to broadcast SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit value corresponding to the SSB status indication field is 10, it indicates that the SCell with SCellIndex i is in a deactivated and SSB not broadcasting state, that is, the SCell is deactivated, and in this state, the network device stops broadcasting SSB on the SCell, and accordingly, the terminal device does not perform service service cell measurement; when the bit value corresponding to the SSB status indication field is 11, it indicates that the SCell with SCellIndex i is in the activated and SSB broadcasting state, that is, the SCell is activated, and in this state, the network device continues to broadcast SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit value corresponding to the SSB status indication field is 00, it indicates that the SCell with SCellIndex i is in the activated and non-SSB broadcasting state, that is, the SCell is activated, and in this state, the network device stops broadcasting SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement.

[0315] Correspondingly, when the bit value corresponding to the SSB status indication field is 10, it indicates that the SCell with SCellIndex i is in a deactivated and SSB broadcast state, that is, the SCell is deactivated, and in this state, the network device continues to broadcast SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit value corresponding to the SSB status indication field is 11, it indicates that the SCell with SCellIndex i is in a deactivated and SSB non-broadcast state, that is, the SCell is deactivated, and in this state, the network device stops broadcasting SSB on the SCell, and accordingly, the terminal device performs service cell measurement. service cell measurement; when the bit value corresponding to the SSB status indication field is 00, it indicates that the SCell with SCellIndex i is in the activated and SSB broadcasting state, that is, the SCell is activated, and in this state, the network device continues to broadcast SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit value corresponding to the SSB status indication field is 01, it indicates that the SCell with SCellIndex i is in the activated and non-SSB broadcasting state, that is, the SCell is activated, and in this state, the network device stops broadcasting SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement.

[0316] Correspondingly, when the bit corresponding to the SSB status indication field is 11, it indicates that the SCell with SCellIndex i is in a deactivated and SSB broadcast state, that is, the SCell is deactivated, and in this state, the network device continues to broadcast SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit corresponding to the SSB status indication field is 00, it indicates that the SCell with SCellIndex i is in a deactivated and SSB non-broadcast state, that is, the SCell is deactivated, and in this state, the network device stops broadcasting SSB on the SCell, and accordingly, the terminal device performs service cell measurement.

[0317] It is understandable that the above MAC CE signaling can also indicate the status of SCell in SSB broadcast.

[0318] Optionally, the first information and the second information can be carried in the same MAC CE signaling to indicate the state of the SCell not broadcasting in the SSB and / or the state of the SCell broadcasting in the SSB.

[0319] It should be noted that the above-mentioned representation method of MAC CE signaling is only a partial example. The energy-saving method provided in the embodiment of the present application does not limit the representation method of MAC CE signaling. For example, it can also be represented by more than two bits, as long as it can indicate that the following SCell is in a deactivated and SSB non-broadcast state, or a deactivated and SSB broadcast state, or an activated and SSB broadcast state, or an activated and SSB non-broadcast state.

[0320] The following describes in detail the case where the first message is carried in the DCI signaling.

[0321] Optionally, the network device sends DCI signaling to the terminal device, where the DCI signaling is used to indicate the status of the Scell ​​in the SSB.

[0322] Exemplarily, the DCI signaling may be expressed as L1 group DCI.

[0323] Optionally, the DCI signaling may be used to indicate a single serving cell, or may be used to indicate multiple serving cells simultaneously.

[0324] Specifically, the specific expression of the DCI signaling may include one or more of the following:

[0325] Method 1: DCI signaling is used to indicate multiple serving cells at the same time.

[0326] It can be understood that multiple serving cells can be described as multiple serving SCells.

[0327] Optionally, the DCI signaling indicates a cell SSB status indication corresponding to each SCell.

[0328] Optionally, in the DCI signaling, the cell SSB status indication may be indicated by a single bit, a double bit, or more than two bits.

[0329] Exemplarily, the cell SSB state indication field may be expressed as Cell SSB state Indication.

[0330] Specifically, when the cell SSB status indication is a single-bit indication, the specific expression of its DCI signaling can be as follows:

[0331] For example, when the bit value corresponding to the cell SSB status indication field is 1, it indicates that the SCell broadcasts SSB; when the bit value corresponding to the cell SSB status indication field is 0, it indicates that the SCell does not broadcast SSB.

[0332] Correspondingly, when the bit value corresponding to the cell SSB status indication field is 0, it indicates that the SCell broadcasts SSB; when the bit value corresponding to the cell SSB status indication field is 0, it indicates that the SCell does not broadcast SSB.

[0333] Optionally, the SCell broadcasting SSB may be SCell activation and SSB broadcasting, or SCell deactivation and SSB broadcasting; the SCell not broadcasting SSB may be SCell deactivation and SSB not broadcasting, or SCell activation and SSB not broadcasting.

[0334] Specifically, when the bit value corresponding to the cell SSB status indication field is 1, it indicates that the SCell is activated and the SSB is broadcast, or the SCell is deactivated and the SSB is broadcast. In this state, the network device continues to broadcast the SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit value corresponding to the cell SSB status indication field is 0, it indicates that the SCell is activated and the SSB is not broadcast, or the SCell is deactivated and the SSB is not broadcast. In this state, the network device stops broadcasting the SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement.

[0335] Accordingly, when the bit value corresponding to the cell SSB status indication field is 0, it indicates that the SCell is activated and the SSB is broadcast, or the SCell is deactivated and the SSB is broadcast. In this state, the network device continues to broadcast the SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit value corresponding to the cell SSB status indication field is 1, it indicates that the SCell is activated and the SSB is not broadcast, or the SCell is deactivated and the SSB is not broadcast. In this state, the network device stops broadcasting the SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement.

[0336] Specifically, when the cell SSB status indication is a two-bit indication, the specific expression of its DCI signaling can be as follows:

[0337] When the bit value corresponding to the cell SSB status indication field is 00, it indicates that the SCell is in a deactivated and SSB broadcast state, that is, the SCell is deactivated, and in this state, the network device continues to broadcast SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit value corresponding to the cell SSB status indication field is 01, it indicates that the SCell is in a deactivated and SSB non-broadcast state, that is, the SCell is deactivated, and in this state, the network device stops broadcasting SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement; when the bit value corresponding to the cell SSB status indication field is 10, it indicates that the SCell is in an activated and SSB broadcast state, that is, the SCell is activated, and in this state, the network device continues to broadcast SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit value corresponding to the cell SSB status indication field is 11, it indicates that the SCell is in an activated and SSB non-broadcast state, that is, the SCell is activated, and in this state, the network device does not broadcast SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement.

[0338] Correspondingly, when the bit value corresponding to the cell SSB status indication field is 01, it indicates that the SCell is in a deactivated and SSB broadcast state, that is, the SCell is deactivated, and in this state, the network device continues to broadcast SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit value corresponding to the cell SSB non-broadcast state indication field is 10, it indicates that the SCell is in a deactivated and SSB non-broadcast state, that is, the SCell is deactivated, and in this state, the network device stops broadcasting SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement; when the bit value corresponding to the cell SSB status indication field is 11, it indicates that the SCell is activated and SSB broadcast state, that is, the SCell is activated, and in this state, the network device continues to broadcast SSB on the SCell, and the terminal device performs service cell measurement; when the bit value corresponding to the cell SSB status indication field is 00, it indicates that the SCell is activated and SSB non-broadcast state, that is, the SCell is activated, and in this state, the network device does not broadcast SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement.

[0339] Accordingly, when the bit value corresponding to the cell SSB status indication field is 10, it indicates that the SCell is in a deactivated and SSB broadcast state, that is, the SCell is deactivated, and in this state, the network device continues to broadcast SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit value corresponding to the cell SSB status indication field is 11, it indicates that the SCell is deactivated and SSB is not broadcast, that is, the SCell is deactivated, and in this state, the network device stops broadcasting SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement; when the bit value corresponding to the cell SSB status indication field is 00, it indicates that the SCell is activated and SSB is broadcast, that is, the SCell is activated, and in this state, the network device continues to broadcast SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit value corresponding to the cell SSB status indication field is 01, it indicates that the SCell is activated and SSB is not broadcast, that is, the SCell is activated, and in this state, the network device does not broadcast SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement.

[0340] Accordingly, when the bit value corresponding to the cell SSB status indication field is 11, it indicates that the SCell is in a deactivated and SSB broadcast state, that is, the SCell is deactivated, and in this state, the network device continues to broadcast SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit value corresponding to the cell SSB status indication field is 00, it indicates that the SCell is deactivated and SSB is not broadcast, that is, the SCell is deactivated, and in this state, the network device stops broadcasting SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement; when the bit value corresponding to the cell SSB status indication field is 01, it indicates that the SCell is activated and SSB is broadcast, that is, the SCell is activated, and in this state, the network device continues to broadcast SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit value corresponding to the cell SSB status indication field is 10, it indicates that the SCell is activated and SSB is not broadcast, that is, the SCell is activated, and in this state, the network device does not broadcast SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement.

[0341] Optionally, the DCI signaling is monitored by the terminal device when the network device configures parameters such as the cell SSBState-RNTI, DCI size, and SCell DCI position indication to the terminal device.

[0342] Optionally, parameters such as cell SSBState-radio network temporary identifier (RNTI), DCI size, and SCell position indication in DCI are carried in the RRC reconfiguration message.

[0343] Optionally, the search space of the DCI signaling may also be configured with parameters such as period, offset, and aggregation level, and the parameters such as period, offset, and aggregation level are carried in an RRC reconfiguration message.

[0344] Specifically, SSBState-RNTI: indicates the RNTI value for scrambling the cyclic redundancy check (CRC) of the DCI format, and is used to monitor DCI signaling to determine whether the SCell broadcasts SSB based on the monitored DCI signaling.

[0345] DCI size: indicates the size of the DCI format.

[0346] SCell position indication in DCI: indicates the bit position corresponding to the SCell in the DCI format information block.

[0347] Figure 10 is a schematic diagram of a DCI signaling format provided by an embodiment of the present application. As shown in Figure 10, the DCI signaling format includes the position of the SCell in the DCI, the DCI size, and the cell.

[0348] Specifically, the cells shown in FIG10 are cell 1 (Cell#1), cell 2 (Cell#2), and cell 3 (Cell#3), and each SCell occupies 1 bit.

[0349] Illustratively, a cell may also be described as an SCell or a serving cell.

[0350] Specifically, the dotted arrows 11, 12 and 13 shown in FIG10 are respectively used to represent the corresponding bit positions of cell 1, cell 2 and cell 3 in the DCI format information block.

[0351] For example, the dotted arrow 11 indicates that starting from bit 0, counting 1 bit is the location of cell 1, the dotted arrow 12 indicates that starting from bit 1, counting 1 bit is the location of cell 2, and the dotted arrow 13 indicates that starting from bit 2, counting 1 bit is the location of cell 3.

[0352] Specifically, the solid double arrow 14 shown in FIG10 is used to represent the size of the DCI format.

[0353] It should be noted that the energy-saving method provided in the embodiments of the present application does not limit the number of SCells in the DCI signaling format and the number of bits occupied by each SCell. FIG10 is merely an example. For example, the number of bits occupied by each SCell may be 3 bits, 5 bits, etc. Specifically, the number of SCells and the number of bits occupied by each SCell can be determined based on actual needs.

[0354] For example, in the DCI signaling format of this method, if each SCell occupies 2 bits, then the location of the corresponding cell can be obtained by counting 2 bits starting from the bit indicated by the dotted arrow (such as the dotted arrow shown in Figure 10). Specifically, taking the dotted arrow 11 shown in Figure 10 as an example, indicating that it starts from bit 0, then counting 2 bits will indicate the location of cell 1. If the dotted arrow 12 shown in Figure 10 indicates that it starts from bit 2, then counting 2 bits will indicate the location of cell 2, and so on.

[0355] Method 2: DCI signaling only indicates a single serving cell.

[0356] Optionally, the DCI signaling indicates an SCell index (SCellIndex) and a cell SSB status indication.

[0357] Exemplarily, the cell SSB state indication may be expressed as Cell SSB state Indication.

[0358] Specifically, when the bit value corresponding to the cell SSB status indication field is 1, it indicates that the SCell broadcasts SSB; when the bit value corresponding to the cell SSB status indication field is 0, it indicates that the SCell does not broadcast SSB.

[0359] Correspondingly, when the bit value corresponding to the cell SSB status indication field is 0, it indicates that the SCell broadcasts SSB; when the bit value corresponding to the cell SSB status indication field is 0, it indicates that the SCell does not broadcast SSB.

[0360] Exemplarily, the SCell broadcasting SSB can be the SCell activation and broadcasting SSB, or the SCell deactivation and broadcasting SSB; the SCell not broadcasting SSB can be the SCell deactivation and not broadcasting SSB, or the SCell activation and not broadcasting SSB.

[0361] It can be understood that the above DCI signaling can also indicate the status of SCell in SSB broadcast.

[0362] Optionally, the first information and the second information can be carried in the same DCI signaling to indicate the state of the SCell not broadcasting in the SSB and / or the state of the SCell broadcasting in the SSB.

[0363] It should be noted that the above-mentioned representation method of DCI signaling is only a partial example. The energy-saving method provided in the embodiment of the present application does not limit the representation method of DCI signaling, as long as it can indicate that the following SCell is in a deactivated and SSB non-broadcast state, or a deactivated and SSB broadcast state, or an activated and SSB broadcast state, or an activated and SSB non-broadcast state.

[0364] S403, if SCell layer 3 RRM measurement is configured, stop SCell layer 3 RRM measurement or measurement result reporting; if SCell BFD is configured, stop SCell BFD measurement; or if SCell CSI reporting is configured, stop SCell CSI detection and reporting.

[0365] Exemplarily, CSI reporting includes periodic reporting, semi-persistent reporting, or aperiodic reporting.

[0366] Optionally, if SCell layer 3 RRM measurement is configured, SCell layer 3 RRM measurement or measurement result reporting is suspended; if SCell BFD is configured, SCell BFD measurement is suspended; if SCell CSI reporting is configured, SCell CSI detection and reporting are suspended.

[0367] In some embodiments, reporting of measurement results of the serving cell (SCell) is stopped or suspended.

[0368] Specifically, the meanings of stop and pause are similar to those described above and will not be repeated here.

[0369] Optionally, if the terminal device has started one or more of the SCell deactivation timer (sCellDeactiveTimer), the partial broadband deactivation timer (bwp-InactiveTimer), the activated BWP, the configured downlink allocation and any configured uplink grant type 2, any physical uplink shared channel (PUSCH) resources of the semi-static CSI report, any configured uplink grant type 1, the hybrid automatic repeat request (HARQ) buffer, and the failure to trigger the consistency of the SCell (listen before talk, LBT), the energy saving processing also includes one or more of the following processing methods:

[0370] Stop the SCell deactivation timer associated with the SCell; stop the partial broadband deactivation timer associated with the SCell; deactivate any activated BWP associated with the SCell; clear any configured downlink allocation and any configured uplink grant type 2 associated with the SCell; clear any PUSCH resources for semi-static CSI reporting associated with the SCell; suspend any configured uplink grant type 1 associated with the SCell; clear all HARQ buffers associated with the SCell and cancel the triggering of consistent LBT failure for the SCell.

[0371] In an embodiment of the present application, through dynamic MAC CE signaling or dynamic indication of DCI signaling, the terminal device can quickly enter the SSB non-broadcast state and stop or suspend any measurement and data transmission of the SCell, saving energy consumption of the terminal device and helping to reduce network energy consumption. At the same time, in the SSB non-broadcast state, system energy saving of the network device on the SCell is achieved.

[0372] It can be understood that in actual needs, when the network device determines that the SCell needs to start SSB broadcasting based on the traffic volume on the terminal device side, it sends an indication message to the terminal device to instruct the terminal device SCell to start SSB broadcasting.

[0373] The following describes in detail, in conjunction with a specific embodiment, an implementation method of sending an indication message to a terminal device to instruct the terminal device to start SSB broadcasting when the network device determines that the SCell needs to start SSB broadcasting based on the traffic volume on the terminal device side.

[0374] FIG11 is a flow chart of an energy-saving method provided by another embodiment of the present application. As shown in FIG11 , the energy-saving method includes the following steps:

[0375] S110, the network device starts SSB broadcasting.

[0376] Exemplarily, the network device enabling SCell SSB includes activating SCell and SSB broadcasting, and deactivating SCell and SSB broadcasting.

[0377] S111, the network device sends the second information, and accordingly, the terminal device obtains the second information, which is used to indicate the status of the SCell in the SSB broadcast.

[0378] Exemplarily, sending the second information may also be described as indicating the second information or transmitting the second information, and obtaining the second information may also be described as receiving the second information.

[0379] Exemplarily, the network device sends the second information through the SCell, and may also send the second information through the PCell or other SCells.

[0380] Exemplarily, the network device sends the second information after resuming the SSB broadcast on the SCell; or after sending the second information, resumes the SSB broadcast on the SCell.

[0381] It should be noted that the energy-saving method provided in the embodiment of the present application does not limit the order in which the network device resumes the SSB broadcast on the SCell and sends the second information.

[0382] Optionally, the state of the SCell in SSB broadcasting may also be described as the state of the SCell being in SSB broadcasting.

[0383] Optionally, when the SCell is in the SSB broadcast state, the SCell sends the SSB.

[0384] Optionally, the state of the SCell in the SSB broadcast may also be described as an initial state where the SCell is in the SSB broadcast state.

[0385] Exemplarily, the state of the SCell in SSB broadcasting may be deactivating the SCell and performing SSB broadcasting, or activating the SCell and performing SSB broadcasting.

[0386] Optionally, the second information is used to indicate the state in which the SCell is deactivated and broadcast in SSB, or the second information is used to indicate the state in which the SCell is activated and broadcast in SSB.

[0387] Optionally, the second information is carried in at least one of the following signalings: RRC signaling, or MAC CE signaling, or DCI signaling.

[0388] It can be understood that the second information can be carried in any one of the above signalings, or can be carried in at least two signalings at the same time.

[0389] Optionally, the RRC signaling includes an RRC reconfiguration message, and the DCI signaling includes layer 1 signaling.

[0390] Exemplarily, the RRC reconfiguration message may also be described as RRC reconfiguration information.

[0391] It should be noted that the above-mentioned first information can also indicate the status of SCell in SSB broadcasting. Based on this scenario, in the energy-saving method provided in the embodiment of the present application, the first information and the second information can be carried in the same signaling to save resources. Exemplarily, the signaling can also be RRC signaling, or MAC CE signaling, or DCI signaling.

[0392] It is understandable that in the energy-saving method provided in the embodiment of the present application, the second information can be directly indicated or indirectly indicated through the first information. In the energy-saving method provided in the embodiment of the present application, there is no limitation on whether the indication information of the SCell's SSB broadcast state and the indication information of the SCell's SSB non-broadcast state are carried in the same signaling, and the specific determination is based on actual needs.

[0393] Optionally, when the second information is carried in MAC CE signaling or DCI signaling, the second information can also be used to indicate SSB broadcast information.

[0394] Optionally, the SSB broadcast information includes at least one of the following information: an SSB broadcast period, a time domain position of the SSB, an SSB broadcast period identifier, and an SSB broadcast information identifier.

[0395] Exemplarily, the time domain position of the SSB can also be described as the time domain position of the SSB transmitted in the half frame.

[0396] Optionally, the mapping relationship between the SSB broadcast period identifier and the SSB broadcast period is carried in the RRC reconfiguration message; or, the mapping relationship between the SSB broadcast information identifier and the SSB broadcast period and the time domain position of the SSB is carried in the RRC reconfiguration message.

[0397] It should be noted that, in the mapping relationship between the SSB broadcast information identifier and the SSB broadcast period and the time domain position of the SSB, the SSB broadcast information identifier and the SSB broadcast period can be regarded as a whole.

[0398] Optionally, when the second information is carried in MAC CE signaling or DCI signaling, the second information may be used to indicate a measurement period or measurement period index for the SCell. For example, the measurement period refers to sf160, sf256, sf320, sf512, sf640, sf1024, and sf1280. sf160 corresponds to 160 subframes, sf256 corresponds to 256 subframes, and so on. The measurement period index corresponds one-to-one to the measurement period. The measurement period or measurement period index is used only when the SCell is configured on the frequency indicated by the measurement target measObjectNR.

[0399] The following describes in detail the implementation manners of carrying the second information in MAC CE signaling and carrying the second information in DCI signaling.

[0400] First, the implementation method of carrying the second information in the MAC CE signaling is described in detail.

[0401] Optionally, in the MAC CE signaling, the MAC subheader includes a logical channel ID, which is used to indicate that the MAC control command is an SCell SSB broadcast command.

[0402] Specifically, the specific expression of the MAC CE signaling may include one or more. The following describes in detail one or more expression of the MAC CE signaling.

[0403] Method 1: Specifically, this method is similar to the expression method corresponding to Figure 5 above, and will not be repeated here.

[0404] Method 2:

[0405] Figure 12 is a schematic diagram of another MAC CE signaling provided in an embodiment of the present application. As shown in Figure 12, the MAC CE signaling includes a cycle index, a serving cell identification field, and a time domain position field of an SSB burst pulse.

[0406] Illustratively, the period index may be expressed as Periodicity Index, the serving cell identifier may be expressed as Serving Cell ID or SCellIndex, and the time domain position of the SSB burst pulse may be expressed as SSB-positionInBurst.

[0407] Optionally, the MAC CE signaling may further include an SCell index (SCellIndex) (the serving cell identifier in FIG12 is the SCellindex) and an SSB broadcast period (not shown in FIG12).

[0408] Specifically, the time domain position of the SSB burst is used to indicate the time domain position of the SSB transmitted in the half-frame. As shown in Figure 12, in the row of the time domain position of the SSB burst, the first bit from the leftmost corresponds to the synchronization signal (SS) or physical broadcast channel (PBCH) block index 0, the second bit corresponds to the SS / PBCH block index 1, and so on.

[0409] Among them, 0 in the bitmap indicates that the corresponding SS / PBCH block is not sent, and 1 indicates that the corresponding SS / PBCH block has been sent.

[0410] Correspondingly, 0 in the bitmap may indicate that the corresponding SS / PBCH block has been sent, and 1 may indicate that the corresponding SS / PBCH block has not been sent.

[0411] Exemplarily, the SS / PBCH block not being sent indicates that the SSB is not broadcast, or the SSB is not sent; the SS / PBCH block being sent indicates that the SSB is broadcast, or the SSB is sent.

[0412] Method 3:

[0413] Figure 13 is a schematic diagram of another MAC CE signaling provided by an embodiment of the present application. As shown in 13a of Figure 13, the MAC CE signaling includes a redundancy bit R, a serving cell identification field, and an SSB broadcast information index field.

[0414] Exemplarily, the value of the redundancy bit R may be 0.

[0415] Exemplarily, the serving cell identifier may be expressed as Serving Cell ID or SCellIndex, and the SSB broadcast information index may be expressed as SSB-BroadcastInfoIndex.

[0416] Specifically, in this mode, the network device indicates the SSB broadcast information list, or the mapping relationship between SSB broadcast information and SSB broadcast information ID, to the terminal device through an RRC reconfiguration message. In this way, the network device only indicates the corresponding SSB broadcast information index or SSB broadcast information ID in the Scell ​​activation MAC CE signaling.

[0417] Exemplarily, the format of the RRC reconfiguration message is as follows:

[0418] Among them, SSBbroadcastToAddModList means adding an SSB broadcast information list, SSBbroadcastconfig means SSB broadcast information configuration, SEQUENCE{…} means that all the parameters enumerated later can be included, and ENUMERATED{…} means taking one of the parameters enumerated later.

[0419] Specifically, the parameters in SEQUENCE{…} include the SSB broadcast index (SSBbroadcastIndex), the time domain position of the SSB burst pulse (SSB-positionInBurst), and the serving cell SSB period (ssb-PeriodicityServingCell).

[0420] Among them, the corresponding number of bits in the time domain position of the SSB burst pulse includes 4 bits, 8 bits and 64 bits, and one bit corresponds to whether a beam is broadcast; the service cell SSB period includes 5ms, 10ms, 20ms20, 40ms, 80ms, 160ms, spare2 and spare1.

[0421] Method 4:

[0422] Figure 13 is a schematic diagram of another MAC CE signaling provided by an embodiment of the present application. As shown in 13b of Figure 13, the MAC CE signaling includes a redundancy bit R, a serving cell identification field, and an SCell measurement period index.

[0423] Optionally, in this mode, MAC CE signaling may indicate a measurement period or measurement period index for the SCell. For example, measurement periods include sf160, sf256, sf320, sf512, sf640, sf1024, and sf1280. sf160 corresponds to 160 subframes, sf256 corresponds to 256 subframes, and so on.

[0424] The measurement period index corresponds to the measurement period one by one.

[0425] For example, an Index value of 0 corresponds to sf160, an Index value of 1 corresponds to sf256, and so on.

[0426] Specifically, the measurement period or measurement period index is used only when the SCell is configured on the frequency indicated by the measurement target measObjectNR.

[0427] Exemplarily, the network device may use the following format for the RRC reconfiguration message:

[0428] Among them, measCycleSCellToAddModList indicates adding an SCell measurement cycle modification list, measCycleSCellconfig indicates the SCell measurement cycle configuration, SEQUENCE{…} indicates that all the parameters enumerated later can be included, and ENUMERATED{…} indicates taking one of the parameters enumerated later.

[0429] Specifically, the parameters in SEQUENCE{…} include the SCell measurement cycle index (measCycleSCellIndex) and the SCell measurement cycle (measCycleSCell).

[0430] Illustratively, the measurement period may be sf160, sf256, sf320, sf512, sf640, sf1024, and sf1280.

[0431] Optionally, mode 4 may be carried in the same MAC CE signaling as mode 2 or mode 3.

[0432] Method 5: In this method, the MAC CE signaling indicates whether the SCell is in a deactivated state with SSB not broadcasting, a deactivated state with SSB broadcasting, a activated state with SSB broadcasting, or a activated state with SSB not broadcasting.

[0433] In this manner, the expression of MAC CE signaling is similar to that described in FIG7 above, and will not be repeated here.

[0434] The following describes in detail the implementation method of carrying the second information in DCI signaling.

[0435] Optionally, the network device sends DCI signaling to the terminal device, where the DCI signaling is used to indicate the status of the Scell ​​in SSB broadcasting.

[0436] Exemplarily, the DCI signaling may be expressed as L1 group DCI.

[0437] Optionally, DCI signaling can be used to indicate multiple serving cells simultaneously.

[0438] It can be understood that multiple serving cells can be described as multiple serving SCells.

[0439] Optionally, the DCI signaling indicates a cell SSB status indication corresponding to each SCell.

[0440] Optionally, in the DCI signaling, the cell SSB status indication may be indicated by a single bit, a double bit, or more than two bits.

[0441] Exemplarily, the cell SSB state indication may be expressed as Cell SSB state Indication.

[0442] Specifically, when the cell SSB status indication is a single-bit indication, the specific expression of its DCI signaling can be as follows:

[0443] When the bit value corresponding to the cell SSB status indication field is 1, it indicates that the SCell broadcasts SSB; when the bit value corresponding to the cell SSB status indication field is 0, it indicates that the SCell does not broadcast SSB.

[0444] Correspondingly, when the bit value corresponding to the cell SSB status indication field is 0, it indicates that the SCell broadcasts SSB; when the bit value corresponding to the cell SSB status indication field is 1, it indicates that the SCell does not broadcast SSB.

[0445] Exemplarily, the SCell broadcasting SSB can be the SCell activation and broadcasting SSB, or the SCell deactivation and broadcasting SSB; the SCell not broadcasting SSB can be the SCell deactivation and not broadcasting SSB, or the SCell activation and not broadcasting SSB.

[0446] Specifically, when the bit value corresponding to the cell SSB status indication field is 1, it indicates that the SCell is activated and the SSB is broadcast, or the SCell is deactivated and the SSB is broadcast. In this state, the network device continues to broadcast the SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit value corresponding to the cell SSB status indication field is 0, it indicates that the SCell is activated and the SSB is not broadcast, or the SCell is deactivated and the SSB is not broadcast. In this state, the network device stops broadcasting the SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement.

[0447] Accordingly, when the bit value corresponding to the cell SSB status indication field is 0, it indicates that the SCell is activated and the SSB is broadcast, or the SCell is deactivated and the SSB is broadcast. In this state, the network device continues to broadcast the SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit value corresponding to the cell SSB status indication field is 1, it indicates that the SCell is activated and the SSB is not broadcast, or the SCell is deactivated and the SSB is not broadcast. In this state, the network device stops broadcasting the SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement.

[0448] Specifically, when the cell SSB status indication is a two-bit indication, the specific expression of its DCI signaling can be as follows:

[0449] When the bit value corresponding to the cell SSB status indication field is 00, it indicates that the SCell is in a deactivated and SSB broadcast state, that is, the SCell is deactivated, and in this state, the network device continues to broadcast SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit value corresponding to the cell SSB status indication field is 01, it indicates that the SCell is in a deactivated and SSB non-broadcast state, that is, the SCell is deactivated, and in this state, the network device stops broadcasting SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement; when the bit value corresponding to the cell SSB status indication field is 10, it indicates that the SCell is in an activated and SSB broadcast state, that is, the SCell is activated, and in this state, the network device continues to broadcast SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit value corresponding to the cell SSB status indication field is 11, it indicates that the SCell is in an activated and SSB non-broadcast state, that is, the SCell is activated, and in this state, the network device does not broadcast SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement.

[0450] Correspondingly, when the bit value corresponding to the cell SSB status indication field is 01, it indicates that the SCell is in a deactivated and SSB broadcast state, that is, the SCell is deactivated, and in this state, the network device continues to broadcast SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit value corresponding to the cell SSB non-broadcast state indication field is 10, it indicates that the SCell is in a deactivated and SSB non-broadcast state, that is, the SCell is deactivated, and in this state, the network device stops broadcasting SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement; when the bit value corresponding to the cell SSB status indication field is 11, it indicates that the SCell is activated and SSB broadcast state, that is, the SCell is activated, and in this state, the network device continues to broadcast SSB on the SCell, and the terminal device performs service cell measurement; when the bit value corresponding to the cell SSB status indication field is 00, it indicates that the SCell is activated and SSB non-broadcast state, that is, the SCell is activated, and in this state, the network device does not broadcast SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement.

[0451] Accordingly, when the bit value corresponding to the cell SSB status indication field is 10, it indicates that the SCell is in a deactivated and SSB broadcast state, that is, the SCell is deactivated, and in this state, the network device continues to broadcast SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit value corresponding to the cell SSB status indication field is 11, it indicates that the SCell is deactivated and SSB is not broadcast, that is, the SCell is deactivated, and in this state, the network device stops broadcasting SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement; when the bit value corresponding to the cell SSB status indication field is 00, it indicates that the SCell is activated and SSB is broadcast, that is, the SCell is activated, and in this state, the network device continues to broadcast SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit value corresponding to the cell SSB status indication field is 01, it indicates that the SCell is activated and SSB is not broadcast, that is, the SCell is activated, and in this state, the network device does not broadcast SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement.

[0452] Accordingly, when the bit value corresponding to the cell SSB status indication field is 11, it indicates that the SCell is in a deactivated and SSB broadcast state, that is, the SCell is deactivated, and in this state, the network device continues to broadcast SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit value corresponding to the cell SSB status indication field is 00, it indicates that the SCell is deactivated and SSB is not broadcast, that is, the SCell is deactivated, and in this state, the network device stops broadcasting SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement; when the bit value corresponding to the cell SSB status indication field is 01, it indicates that the SCell is activated and SSB is broadcast, that is, the SCell is activated, and in this state, the network device continues to broadcast SSB on the SCell, and accordingly, the terminal device performs service cell measurement; when the bit value corresponding to the cell SSB status indication field is 10, it indicates that the SCell is activated and SSB is not broadcast, that is, the SCell is activated, and in this state, the network device does not broadcast SSB on the SCell, and accordingly, the terminal device does not perform service cell measurement.

[0453] Optionally, the DCI signaling is monitored by the terminal device when the network device configures parameters such as the cell SSBState-RNTI, DCI size, and SCell DCI position indication to the terminal device.

[0454] Optionally, parameters such as cell SSBState-radio network temporary identifier (RNTI), DCI size, and SCell position indication in DCI are carried in the RRC reconfiguration message.

[0455] Optionally, the search space of the DCI signaling may also be configured with parameters such as period, offset, and aggregation level, and the parameters such as period, offset, and aggregation level are carried in an RRC reconfiguration message.

[0456] Specifically, SSBState-RNTI: indicates the RNTI value for scrambling the cyclic redundancy check (CRC) of the DCI format, and is used to monitor DCI signaling to determine whether the SCell broadcasts SSB based on the monitored DCI signaling.

[0457] DCI size: indicates the size of the DCI format.

[0458] SCell position indication in DCI: indicates the bit position corresponding to the SCell in the DCI format information block.

[0459] The schematic diagram of the DCI signaling format is similar to the above-mentioned Figure 10 and will not be repeated here.

[0460] The following describes in detail the method of simultaneously indicating SSB broadcast information in the DCI signaling.

[0461] Optionally, in the DCI signaling, corresponding to each SCell, N bits of cell SSB broadcast information may be additionally indicated, the value of which corresponds to the SSB broadcast information index or SSB broadcast information ID.

[0462] For example, N can be any positive integer such as 1, 2, or 3.

[0463] For example, the bit number corresponding to each SCell is 3 bits (3 bits), that is, the value of N is 3.

[0464] Specifically, when the value of the N-bit cell SSB broadcast information corresponds to the SSB broadcast information Index, 000: corresponds to the SSB broadcast information with Index 0; 001: corresponds to the SSB broadcast information with Index 1; 010: corresponds to the SSB broadcast information with Index 2, and so on. Examples are not given one by one here.

[0465] When the value of the N-bit cell SSB broadcast information corresponds to the SSB broadcast information ID, 000: corresponds to the SSB broadcast information with ID 0; 001: corresponds to the SSB broadcast information with ID 1; 010: corresponds to the SSB broadcast information with ID 2, and so on. Examples are not given one by one here.

[0466] Specifically, in this mode, the network device indicates the SSB broadcast information list, or the mapping relationship between SSB broadcast information and SSB broadcast information ID, to the terminal device through an RRC reconfiguration message. In this way, the network device only indicates the corresponding SSB broadcast information index or SSB broadcast information ID in the Scell ​​activation MAC CE signaling.

[0467] Exemplarily, the format of the RRC reconfiguration message is as follows:

[0468] Among them, SSBbroadcastToAddModList means adding an SSB broadcast information list, SSBbroadcastconfig means SSB broadcast information configuration, SEQUENCE{…} means that all the parameters enumerated later can be included, and ENUMERATED{…} means taking one of the parameters enumerated later.

[0469] Specifically, the parameters in SEQUENCE{…} include the SSB broadcast index (SSBbroadcastIndex), the time domain position of the SSB burst pulse (SSB-positionInBurst), and the serving cell SSB period (ssb-PeriodicityServingCell).

[0470] Among them, the corresponding number of bits in the time domain position of the SSB burst pulse includes 4 bits, 8 bits and 64 bits, and one bit corresponds to whether a beam is broadcast; the service cell SSB period includes 5ms, 10ms, 20ms20, 40ms, 80ms, 160ms, spare2 and spare1.

[0471] Optionally, in this method, DCI signaling may indicate a measurement period or measurement period index for the SCell. For example, measurement periods include sf160, sf256, sf320, sf512, sf640, sf1024, and sf1280. sf160 corresponds to 160 subframes, sf256 corresponds to 256 subframes, and so on.

[0472] The measurement period index corresponds to the measurement period one by one.

[0473] For example, an Index value of 0 corresponds to sf160, an Index value of 1 corresponds to sf256, and so on.

[0474] Specifically, the measurement period or measurement period index is used only when the SCell is configured on the frequency indicated by the measurement target measObjectNR.

[0475] Figure 14 is a schematic diagram of another DCI signaling format provided by an embodiment of the present application. As shown in Figure 14, the DCI signaling format includes the position of the SCell in the DCI, the DCI size, and the cell identifier.

[0476] Specifically, the cell identifiers shown in Figure 14 are block 1 (Block#1), block 2 (Block#2), and block 3 (Block#3). Each block includes a cell with a bit of 1 bit and a cell with a bit of N bits. The cell with a bit of N bits is used to indicate N bits of cell SSB broadcast information. Its value corresponds to the SSB broadcast information index or SSB broadcast information ID. The correspondence between the SSB broadcast information index or SSB broadcast information ID and the bit value is as described above when N is 3 bits, and will not be repeated here.

[0477] Illustratively, a cell may also be described as an SCell or a serving cell.

[0478] Specifically, the dotted arrow 41 , the dotted arrow 42 and the dotted arrow 43 shown in FIG14 are respectively used to indicate the corresponding bit positions of block 1 , block area 2 and block 3 in the DCI format information block.

[0479] For example, the dotted arrow 41 indicates that starting from the 0th bit, the first bit is the location of the cell with the bit of 1 in block 1, the dotted arrow 42 indicates that starting from the 5th bit, the first bit is the location of the cell with the bit of 1 in block 2, and the dotted arrow 43 indicates that starting from the 9th bit, the first bit is the location of the cell with the bit of 1 in block 3.

[0480] Specifically, the solid double arrow 44 shown in FIG14 is used to represent the size of the DCI format.

[0481] Optionally, in this method, DCI signaling may indicate a measurement period or measurement period index for the SCell. For example, measurement periods include sf160, sf256, sf320, sf512, sf640, sf1024, and sf1280. sf160 corresponds to 160 subframes, sf256 corresponds to 256 subframes, and so on.

[0482] The measurement period index corresponds to the measurement period one by one.

[0483] For example, an Index value of 0 corresponds to sf160, an Index value of 1 corresponds to sf256, and so on.

[0484] Specifically, the measurement period or measurement period index is used only when the SCell is configured on the frequency indicated by the measurement target measObjectNR.

[0485] It should be noted that the energy-saving method provided in the embodiments of the present application does not limit the number of SCells in the DCI signaling format and the number of bits occupied by each SCell. FIG14 is merely an example. For example, the number of bits occupied by each SCell may be 3 bits, 5 bits, etc. Specifically, the number of SCells and the number of bits occupied by each SCell can be determined based on actual needs.

[0486] S112, searching for SSB according to the second information, and performing one or more of the following operations: layer 3 RRM measurement or measurement result reporting of the SCell; BFD measurement of the SCell; or CSI detection and reporting of the SCell.

[0487] Specifically, the terminal device searches for SSB according to the SSB broadcast information indicated in the second information, thereby performing downlink (DL) time and frequency synchronization and layer 1 / layer 3 measurement.

[0488] Specifically, one or more of performing layer 3 RRM measurement or measurement result reporting of the SCell, performing BFD measurement of the SCell, and performing CSI detection and reporting of the SCell.

[0489] Exemplarily, CSI reporting includes periodic reporting, semi-persistent reporting, or aperiodic reporting.

[0490] In some embodiments, measurement result reporting of a serving cell, SCell, is performed.

[0491] It should be noted that the specific operations performed are determined based on the actual configuration of the terminal device, and the energy-saving method provided in the embodiment of the present application does not limit this.

[0492] In the embodiments of the present application, the network device indicates the SSB broadcast status of the SCell to the terminal device, enabling the terminal device to quickly detect the SSB signal, initiate Layer 3 measurement, L1 measurement, or BFD measurement on the SCell, perform DL time-frequency synchronization, and perform Layer 1 / Layer 3 measurements, thereby improving the user experience. Furthermore, the terminal device can more quickly learn the SSB broadcast period and beam broadcast status, enabling faster data transmission and improving terminal device performance.

[0493] Optionally, the second information is also used to indicate a BWP identifier, further enabling the terminal device to switch to the indicated BWP identifier according to the second information.

[0494] It should be noted that both the first information and the second information can be used to indicate the state of deactivating the SCell and broadcasting the SCell in the SSB, or the state of activating the SCell and broadcasting the SCell in the SSB, or the state of deactivating the SCell and not broadcasting the SCell in the SSB, or the state of activating the SCell and not broadcasting the SCell in the SSB. In this scenario, the first information and the second information are optionally carried in the same signaling to save resources.

[0495] Exemplarily, the signaling includes at least one of the following: RRC signaling, or MAC CE signaling, or DCI signaling.

[0496] It should be noted that the energy-saving method provided in the embodiment of the present application is also applicable to the scenario where the terminal device sends uplink (UL) activation information (wakeup signal, WUS) to the SCell and / or PCell under the configuration of the network device.

[0497] The following first describes a specific application scenario in which a terminal device sends a UL WUS to an SCell and / or PCell under the configuration of a network device so that the network device instructs the terminal device to enter an SSB broadcast state.

[0498] Figure 15 is a schematic diagram of UL WUS activation SSB broadcasting according to an embodiment of the present application. As shown in Figure 15, the UL WUS activation SSB broadcasting scenario includes long-period SSB, short-period SSB, and a group of multiple consecutive SSBs.

[0499] Among them, the solid arrow 51 indicates that the network device sends an RRC reconfiguration message to the terminal device, and the RRC reconfiguration message includes UL WUS or RACH configuration; the solid arrow 52 indicates that the terminal device sends UL WUS to the network device; the solid arrow 53 indicates that the network device indicates SSB broadcast information to the terminal device.

[0500] Specifically, the network device sends a group of continuous SSBs with a long period on the SCell, and the terminal device sends a UL WUS to the SCell under the configuration of the network device. After receiving the UL WUS sent by the terminal device, the network device sends a group of continuous SSBs with a short period to the network device.

[0501] For example, a group of consecutive SSBs may be expressed as an SSB burst.

[0502] Figure 16 is another schematic diagram of UL WUS activation SSB broadcast provided by an embodiment of the present application. As shown in Figure 16, the scenario of UL WUS activation SSB broadcast includes short-period SSB and multiple groups of continuous SSB.

[0503] Among them, the solid arrow 61 indicates that the network device sends an RRC reconfiguration message to the terminal device, and the RRC reconfiguration message includes UL WUS or RACH configuration; the solid arrow 62 indicates that the terminal device sends UL WUS to the network device; the solid arrow 63 indicates that the network device indicates SSB broadcast information to the terminal device.

[0504] Specifically, the network device does not send a long-period continuous set of SSBs on the SCell. The terminal device sends a UL WUS to the SCell under the configuration of the network device. After receiving the UL WUS sent by the terminal device, the network device sends a periodic set of continuous SSBs to the network device.

[0505] In one case, the network device may start broadcasting SSB before the network device indicates the SSB broadcast information to the terminal device as indicated by the solid arrow 63 in Figure 16, and the terminal device may search or monitor SSB according to the SSB period and / or SSBinburst indicated in the RRC reconfiguration message in advance by the network device.

[0506] In another case, the network device may start broadcasting SSB after the network device indicates the SSB broadcast information to the terminal device as indicated by the solid arrow 63 in Figure 16, and the terminal device may search for SSB according to the period and / or SSBinburst in the SSB broadcast information indicated by the network device.

[0507] For example, a group of consecutive SSBs may be expressed as an SSB burst.

[0508] The following describes in detail an energy saving method applicable to a scenario where a terminal device sends uplink (UL) activation information (wakeup signal, WUS) to a network device in conjunction with specific embodiments.

[0509] FIG17 is a flow chart of an energy-saving method provided by another embodiment of the present application. As shown in FIG17 , the energy-saving method includes the following steps:

[0510] S170, the network device sends third information, and accordingly, the terminal device obtains the third information, where the third information is used to configure RACH parameters on the SCell.

[0511] Exemplarily, indicating the third information may also be described as sending the third information or transmitting the third information, and obtaining the third information may also be described as receiving the third information.

[0512] Optionally, the third information is carried in an RRC reconfiguration message.

[0513] Optionally, the RACH parameters include a mapping relationship between RACH resources and SSB broadcast periods.

[0514] Specifically, the network device configures the RACH parameter configuration on the SCell through the RRC reconfiguration message, which is used to request the SCell SSB broadcast.

[0515] For example, the mapping relationship between RACH resources and SSB broadcast periods may be shown in the following table: Table 1 is a mapping relationship between RACH resources and SSB broadcast periods provided in an embodiment of the present application.

[0516] Table 1

[0517] As shown in Table 1, when the RACH resource configuration value is 1, the corresponding SSB broadcast period is 5ms; when the RACH resource configuration value is 2, the corresponding SSB broadcast period is 10ms; when the RACH resource configuration value is 3, the corresponding SSB broadcast period is 20ms; when the RACH resource configuration value is 4, the corresponding SSB broadcast period is 40ms; when the RACH resource configuration value is 8, the corresponding SSB broadcast period is 80ms; when the RACH resource configuration value is 6, the corresponding SSB broadcast period is 160ms. For example, when the preamble sequence is 1, the corresponding SSB broadcast period is 5ms; when the preamble sequence is 2, the corresponding SSB broadcast period is 10ms, and so on.

[0518] Table 2 is another mapping relationship between RACH resources and SSB broadcast periods provided in an embodiment of the present application.

[0519] Table 2

[0520] As shown in Table 2, when the value of the RACH resource configuration is 1, the corresponding SSB broadcast period can be 5ms or 10ms; when the value of the RACH resource configuration is 2, the corresponding SSB broadcast period can be 20ms or 40ms; when the value of the RACH resource configuration is 3, the corresponding SSB broadcast period can be 80ms or 160ms.

[0521] In this mapping relationship, the network device can select one of the two periods of the SSB broadcast period and indicate it to the terminal device based on the mapping relationship between the RACH resource and the SSB broadcast period.

[0522] It should be noted that the mapping relationship between RACH resources and SSB broadcast periods shown in Tables 1 and 2 above is only a partial example, and the energy-saving method provided in the embodiment of the present application does not limit this mapping relationship.

[0523] S171, the terminal device sends an uplink random access sequence.

[0524] Optionally, the terminal device sending an uplink random access sequence can also be described as the terminal device sending a scheduling request.

[0525] Optionally, the uplink random access sequence is used to request the second information.

[0526] It is understandable that the terminal device can send an uplink random access sequence to the network device based on its own traffic demand or the traffic threshold configured by the network device, so that the network device instructs the SCell SSB broadcast. Exemplarily, the traffic threshold configured by the network device is configured by the network device through an RRC reconfiguration message.

[0527] Exemplarily, the SCell SSB broadcast may be SCell activation and SSB broadcast, or SCell deactivation and SSB broadcast.

[0528] S172, the network device sends the second information, and accordingly, the terminal device obtains the second information, which is used to indicate the status of the SCell in the SSB broadcast.

[0529] Exemplarily, sending the second information may also be described as indicating the second information or transmitting the second information, and obtaining the second information may also be described as receiving the second information.

[0530] Exemplarily, the network device sends the second information through the SCell, and may also send the second information through the PCell or other SCells.

[0531] Exemplarily, the network device sends the second information after resuming the SSB broadcast on the SCell; or after sending the second information, resumes the SSB broadcast on the SCell.

[0532] It should be noted that the energy-saving method provided in the embodiment of the present application does not limit the order in which the network device resumes the SSB broadcast on the SCell and sends the second information.

[0533] Optionally, the state of the SCell in SSB broadcasting may also be described as the state of the SCell being in SSB broadcasting.

[0534] Optionally, when the SCell is in the SSB broadcast state, the SCell sends the SSB.

[0535] Optionally, the state of the SCell in the SSB broadcast may also be described as an initial state where the SCell is in the SSB broadcast state.

[0536] Exemplarily, the state of the SCell in SSB broadcasting may be deactivating the SCell and performing SSB broadcasting, or activating the SCell and performing SSB broadcasting.

[0537] Optionally, the second information is used to indicate the state in which the SCell is deactivated and broadcast in SSB, or the second information is used to indicate the state in which the SCell is activated and broadcast in SSB.

[0538] Optionally, the second information is carried in at least one of the following signalings: RRC signaling, or MAC CE signaling, or DCI signaling.

[0539] It can be understood that the second information can be carried in any one of the above signalings, or can be carried in at least two signalings at the same time.

[0540] Optionally, the RRC signaling includes an RRC reconfiguration message, and the DCI signaling includes layer 1 signaling and / or layer 3 signaling.

[0541] Exemplarily, the RRC reconfiguration message may also be described as RRC reconfiguration information.

[0542] Optionally, when the second information is carried in MAC CE signaling or DCI signaling, the second information can also be used to indicate SSB broadcast information.

[0543] Optionally, the SSB broadcast information includes at least one of the following information: an SSB broadcast period, a time domain position of the SSB, an SSB broadcast period identifier, and an SSB broadcast information identifier.

[0544] Optionally, the mapping relationship between the SSB broadcast period identifier and the SSB broadcast period is carried in the RRC reconfiguration message; or, the mapping relationship between the SSB broadcast information identifier and the SSB broadcast period and the time domain position of the SSB is carried in the RRC reconfiguration message.

[0545] It should be noted that, in the mapping relationship between the SSB broadcast information identifier and the SSB broadcast period and the time domain position of the SSB, the SSB broadcast information identifier and the SSB broadcast period can be regarded as a whole.

[0546] Optionally, when the second information is carried in MAC CE signaling or DCI signaling, the second information can also be used to indicate the measurement period or measurement period index of the SCell. For example, the measurement period refers to sf160, sf256, sf320, sf512, sf640, sf1024, and sf1280. sf160 corresponds to 160 subframes, sf256 corresponds to 256 subframes, and so on.

[0547] The measurement period index corresponds to the measurement period one by one.

[0548] For example, an Index value of 0 corresponds to sf160, an Index value of 1 corresponds to sf256, and so on.

[0549] Specifically, the measurement period or measurement period index is used only when the SCell is configured on the frequency indicated by the measurement target measObjectNR.

[0550] Optionally, the MAC CE signaling used to carry the second information includes random access response (RAR) signaling.

[0551] The following describes in detail the implementation of random access response signaling.

[0552] Specifically, the MAC subheader includes a logical channel ID, which is used to indicate that the MAC control command is an enhanced random access response, which includes SSB broadcast information.

[0553] In a possible implementation, a periodicity index (PeriodicityIndex) MAC sub-protocol data unit (PDU) and an SSB-PositionInBurst (SSB-PositionInBurst) MAC sub-PDU are added to the original RAR signaling.

[0554] Figure 18 is a schematic diagram of another MAC CE signaling provided by an embodiment of the present application. As shown in Figure 18, the period index and the time domain position of the SSB burst pulse represented by the dotted box 80 are newly added MAC sub-PDUs in the original RAR signaling.

[0555] As shown in FIG18 , the backoff indicator (BI) field is used to identify the overload condition of the cell; the random access preamble identifier (PAPID) field is used to identify the transmitted random access preamble.

[0556] In another possible implementation, a SSB broadcast information index (SSB-BroadcastInfoIndex) MAC sub-PDU is added to the original MAC RAR command.

[0557] Figure 19 is a schematic diagram of another MAC CE signaling provided by an embodiment of the present application. As shown in Figure 19, the SSB broadcast information index represented by the dotted box 90 is a newly added MAC sub-PDU in the original RAR signaling.

[0558] As shown in FIG. 19 , the meanings of the BI field and the PAPID field identifiers are similar to those described above and are not repeated here.

[0559] Optionally, when the second information is carried in DCI signaling, its specific implementation is similar to the implementation when the first information is carried in DCI signaling in the above step S402, and is not repeated here.

[0560] S173 , searching for the SSB according to the second information, and performing one or more of the following operations: layer 3 RRM measurement or measurement result reporting of the SCell; BFD measurement of the SCell; or CSI detection and reporting of the SCell.

[0561] Specifically, the implementation method is similar to that in the above step S112 and will not be repeated here.

[0562] In an embodiment of the present application, in a scenario where a terminal device sends a UL WUS to a network device, the network device indicates SSB broadcast information through RAR and DCI signaling, so that the terminal device can quickly detect the SSB signal and achieve rapid SCell SSB activation, thereby achieving energy saving of the network device and improving the user experience.

Among them, the control plane (CP) interface may be Fs-C, such as F1-C, and the user plane (UP) interface may be Fs-U, such as F1-U. DU and RU can cooperate to jointly implement the functions of the physical (PHY) layer. A DU can be connected to one or more RUs. The functions of the DU and RU can be configured in various ways according to the design. For example, the DU is configured to implement baseband functions, and the RU is configured to implement mid-RF functions.

[0624] Specifically, baseband processing on the CU and DU can be divided according to the protocol layers of the wireless network. For example, the functions of the packet data convergence protocol (PDCP) layer and above are set in the CU, while the functions of the protocol layers below PDCP, such as the radio link control (RLC) layer and the MAC layer, are set in the DU. For another example, the CU implements the functions of the RRC layer and PDCP layer, while the DU implements the functions of the RLC layer, MAC layer, and PHY layer.
