Optionally, the "protocol" may refer to a standard protocol in the field of communications, such as an LTE protocol, an NR protocol, and related protocols used in future communication systems, which is not specifically limited in this application.

[0064] In addition, the term "indication" can be a direct indication, an indirect indication, or an indication of an associated relationship. For example, A indicates B, which can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an associated relationship between A and B. The term "correspondence" can mean that there is a direct or indirect correspondence between the two, or it can mean that there is an associated relationship between the two, or it can mean a relationship between indication and being indicated, configuration and being configured, etc. In addition, the description "at the time of..." involved in the embodiments of the present application can be interpreted as "if" or "if" or "when..." or "in response to". Similarly, depending on the context, the phrase "if it is determined" or "if (the stated condition or event) is detected" can be interpreted as "when it is determined" or "in response to the determination" or "when (the stated condition or event) is detected" or "in response to detecting (the stated condition or event)". The term "predefined" or "predefined rules" can be implemented by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in a device (for example, including a terminal device and a network device), and this application does not limit its specific implementation method. For example, predefined can refer to what is defined in the protocol. It should also be understood that in the embodiment of the present application, the "protocol" may refer to a standard protocol in the field of communications, for example, it may include LTE protocol, NR protocol and related protocols used in future communication systems, and this application does not limit this. In addition, in the embodiment of the present application, the term "and / or" is merely a description of the association relationship of associated objects, indicating that three relationships may exist. Specifically, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the previous and subsequent associated objects are in an "or" relationship.

[0065] FIG1 is an example of a system framework provided by an embodiment of the present application.

[0066] As shown in Figure 1, a communication system 100 may include a terminal device 110 and a network device 120. The network device 120 may communicate with the terminal device 110 via an air interface. The terminal device 110 and the network device 120 support multi-service transmission.

[0067] It should be understood that the embodiments of the present application are only illustrative of the communication system 100, but the embodiments of the present application are not limited thereto. That is, the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Internet of Things (IoT) system, Narrow Band Internet of Things (NB-IoT) system, enhanced Machine-Type Communications (eMTC) system, 5G communication system (also known as New Radio (NR) communication system), or future communication systems.

[0068] In the communication system 100 shown in Figure 1, the network device 120 may be an access network device that communicates with the terminal device 110. The access network device may provide communication coverage for a specific geographical area and may communicate with the terminal device 110 (eg, UE) located within the coverage area.

[0069] The network device 120 may be an evolved Node B (eNB or eNodeB) in a Long Term Evolution (LTE) system, or a Next Generation Radio Access Network (NG RAN) device, or a base station (gNB) in an NR system, or a wireless controller in a Cloud Radio Access Network (CRAN), or the network device 120 may be a relay station, an access point, an in-vehicle device, a wearable device, a hub, a switch, a bridge, a router, or a network device in a future evolved Public Land Mobile Network (PLMN), etc.

[0070] The terminal device 110 may be any terminal device, including but not limited to a terminal device connected to the network device 120 or other terminal devices by wire or wireless connection.

[0071] For example, the terminal device 110 may refer to an access terminal, user equipment (UE), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user apparatus. An access terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, an IoT device, a satellite handheld terminal, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a 5G network, or a terminal device in a future evolution network, etc.

[0072] The terminal device 110 can be used for device-to-device (D2D) communication.

[0073] The wireless communication system 100 may also include a core network device 130 for communicating with the base station. The core network device 130 may be a 5G core network (5G Core, 5GC) device, such as an Access and Mobility Management Function (AMF), an Authentication Server Function (AUSF), a User Plane Function (UPF), or a Session Management Function (SMF). Optionally, the core network device 130 may also be an Evolved Packet Core (EPC) device of an LTE network, such as a Session Management Function + Core Packet Gateway (SMF+PGW-C) device. It should be understood that SMF+PGW-C can simultaneously implement the functions that can be implemented by SMF and PGW-C. During the network evolution process, the core network devices mentioned above may also be called other names, or new network entities may be formed by dividing the functions of the core network, which is not limited in the embodiments of the present application.

[0074] The functional units in the communication system 100 may also establish connections and implement communication via next generation (NG) network interfaces.

[0075] For example, the terminal device establishes an air interface connection with the access network device through the NR interface for transmitting user plane data and control plane signaling; the terminal device can establish a control plane signaling connection with the AMF through the NG interface 1 (referred to as N1); the access network device, such as the next generation wireless access base station (gNB), can establish a user plane data connection with the UPF through the NG interface 3 (referred to as N3); the access network device can establish a control plane signaling connection with the AMF through the NG interface 2 (referred to as N2); the UPF can establish a control plane signaling connection with the SMF through the NG interface 4 (referred to as N4); the UPF can exchange user plane data with the data network through the NG interface 6 (referred to as N6); the AMF can establish a control plane signaling connection with the SMF through the NG interface 11 (referred to as N11); the SMF can establish a control plane signaling connection with the PCF through the NG interface 7 (referred to as N7).

[0076] Figure 1 exemplifies a base station, a core network device, and two terminal devices. Optionally, the wireless communication system 100 may include multiple base station devices, and each base station may include a different number of terminal devices within its coverage area, though this is not a limitation in this application. It should be understood that in the embodiments of this application, any device with communication functionality in the network / system may be referred to as a communication device. Taking the communication system 100 shown in Figure 1 as an example, the communication device may include a network device 120 and a terminal device 110 with communication functionality. Network device 120 and terminal device 110 may be the devices described above and will not be described in detail here. The communication device may also include other devices in the communication system 100, such as a network controller, a mobility management entity, and other network entities, though this is not a limitation in this embodiment of this application. It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between associated objects, indicating that three possible relationships exist. For example, "A and / or B" may represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the associated objects are in an "or" relationship.

[0077] It is worth noting that the bit rate and power consumption of network equipment in the fifth-generation mobile communication technology (5-Generation, 5G) are high, and the power consumption of a single network device is typically four times that of 4G. In addition, with the complexity and diversity of services, network architectures are also developing in a variety of ways, such as integrated air-ground-space network architectures. Therefore, the energy consumption of network equipment in the future sixth-generation mobile communication technology (6-Generation, 6G) will become even greater. However, excessive network equipment energy consumption will bring huge network operation and maintenance costs to operators' network operations. Therefore, how to reduce the energy consumption of network equipment is a technical problem that urgently needs to be solved in this field.

[0078] In view of this, embodiments of the present application provide a network energy-saving method, a cell wake-up method, a terminal device, and a network device, which can reduce the energy consumption of the network device.

[0079] Figure 2 is a schematic flow chart of a network energy-saving method 210 provided in an embodiment of the present application. The network energy-saving method 210 can be interactively executed by a terminal device and a network device for providing a target cell. For example, the network energy-saving method 210 can be interactively executed by the terminal device shown in Figure 1 and the access network device shown in Figure 1. Of course, the network energy-saving method 210 can also be understood as a method interactively executed by a terminal device and the target cell, and this application is not limited to this.

[0080] As shown in FIG. 2 , the method 210 may include:

[0081] S211, the terminal device receives first indication information sent by the target cell, where the first indication information is used to indicate that the target cell will enter an energy-saving state.

[0082] In other words, the terminal device receives the first indication information sent by the target cell.

[0083] In other words, the terminal device receives the first indication information sent by the network device through the target cell.

[0084] Exemplarily, the network device for providing the target cell sends the first indication information to the terminal device at a first moment. Optionally, the first moment is the moment when the network device for providing the target cell determines that the target cell enters the energy-saving state, or the first moment is before the moment when the network device for providing the target cell determines that the target cell enters the energy-saving state, or the first moment is the moment when the target cell enters the energy-saving state, or the first moment is before the moment when the target cell enters the energy-saving state.

[0085] In the embodiments of the present application, an energy-saving state is introduced for the target cell, which can reduce the energy consumption of the network equipment used to provide the target cell. In addition, when the target cell determines to enter the energy-saving state, the terminal device receives the first indication information sent by the target cell indicating that the target cell will enter the energy-saving state. This can ensure that the terminal device is aware of the state of the target cell in a timely manner, thus avoiding the situation where communication failure occurs due to the terminal device being unaware that the target cell has entered the energy-saving state.

[0086] It is worth noting that the term "wake up" involved in this application can also be equivalently replaced by "activation", "enablement" or terms with similar meanings, the term "sleep" can also be equivalently replaced by "deactivation", "disenablement" or terms with similar meanings, the term "energy-saving state" can also be equivalently replaced by "normal state," "deactivation state," "disenablement state," "non-activated state," "non-enabled state" or terms with similar meanings, the state of the target cell after activation can also be called "non-energy-saving state," "activation state," "enablement state" or terms with similar meanings, and this application does not make specific restrictions on this.

[0087] In some embodiments, the energy-saving state refers to: prohibiting the target cell from performing uplink reception or prohibiting the target cell from receiving uplink reception except for a wake-up request for waking up the target cell, and prohibiting the target cell from performing downlink transmission.

[0088] In some embodiments, the energy-saving state refers to: prohibiting the target cell from performing uplink reception or prohibiting the target cell from receiving uplink reception except for a wake-up request for waking up the target cell, and prohibiting the target cell from sending downlink transmission except for a downlink discovery signal.

[0089] Exemplarily, the uplink reception may be reception of an uplink channel or an uplink signal. The uplink channel may include a physical random access channel (PRACH), a physical uplink control channel (PUCCH), a physical uplink shared channel (PUSCH), etc. The uplink reference signal may include an uplink demodulation reference signal (DMRS), a sounding reference signal (SRS), a phase tracking reference signal (PT-RS), etc. Among them, the uplink DMRS can be used for demodulation of the uplink channel, the SRS can be used for measurement of the uplink channel, synchronization or phase tracking on the uplink time and frequency, and the PT-RS can also be used for measurement of the uplink channel, synchronization or phase tracking on the uplink time and frequency.

[0090] Exemplarily, the downlink transmission may be the transmission of a downlink channel or a downlink signal. The downlink channel may include a physical downlink control channel (PDCCH), a physical downlink shared channel (PDSCH), a paging control channel (PCCH), a physical broadcast channel (PBCH), a paging channel (PCH), a primary common control physical channel (P-CCPCH), etc. The downlink reference signal may include: a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a synchronization signal and / or a physical broadcast channel block (SSB), a channel state information reference signal (CSI-RS) or a downlink demodulation reference signal (DMRS), etc., wherein the downlink DMRS can be used for demodulation of the downlink channel. Of course, from the perspective of transmission of system messages, the downlink transmission may also include transmission of system information (SI), master information block (MIB) and system information block (SIB).

[0091] Exemplarily, when the target cell is in the energy-saving state, it may receive a wake-up request for waking up the target cell, which is sent by other cells or a coverage cell of the target cell.

[0092] Exemplarily, the target cell is prohibited from receiving signals and information from other cells in the energy-saving state.

[0093] Exemplarily, the target cell is prohibited from sending signals and information to other cells in the energy-saving state.

[0094] Exemplarily, the downlink discovery signal is used by the terminal device to discover the target cell.

[0095] It is worth noting that the embodiment of the present application does not limit the specific type of the downlink discovery signal. For example, the downlink discovery signal can be SSB, CSI-RS or other downlink signals. For example, the downlink reference signal can also be a reference signal specifically used to discover the target cell.

[0096] It should be understood that the embodiments of the present application may include physical channels or reference signals with the same name but different functions as those mentioned above, or may include physical channels or reference signals with different names but the same functions as those mentioned above, and the present application does not limit this. In addition, it should be understood that the terms "downlink" and "uplink" involved in the present application are used to indicate the transmission direction of signals or data, where "downlink" is used to indicate that the transmission direction of signals or data is the direction from the site to the user equipment of the cell, and "uplink" is used to indicate that the transmission direction of signals or data is the direction from the user equipment of the cell to the site.

[0097] In some embodiments, the terminal device is in a connected state; the method 210 may further include:

[0098] The terminal device switches the serving cell of the terminal device from the target cell to a neighboring cell of the target cell.

[0099] Exemplarily, after receiving the first indication information, the terminal device switches the serving cell of the terminal device from the target cell to a neighboring cell of the target cell. In other words, the first indication information can be used to trigger the terminal device to switch the serving cell of the terminal device.

[0100] In some embodiments, the terminal device is in an inactive state or an idle state; the method 210 may further include:

[0101] The terminal device performs a cell reselection operation.

[0102] Exemplarily, after the terminal device receives the first indication information, the terminal device performs a cell reselection operation. In other words, after the terminal device receives the first indication information, the terminal device performs a cell reselection operation to reselect the terminal device's resident cell. In other words, the first indication information can be used to trigger the terminal device to perform a cell reselection operation, or the first indication information can be used to trigger the terminal device to switch the terminal device's resident cell.

[0103] It is worth noting that the Radio Resource Control (RRC) state of the terminal device may include: RRC deactivation (RRC_INACTIVE) state, RRC idle (RRC_IDLE) state and RRC connection (RRC_CONNECTED) state.

[0104] Among them, for the RRC_CONNECTED state, there is an RRC connection between the network device and the terminal device, and there is a UE AS context between the network device and the terminal device, that is, the network device knows the location of the terminal device at a specific cell level, the mobility of the terminal device is controlled by the network device, and unicast data can be transmitted between the network device and the terminal device. For the RRC_IDLE state, there is no UE access stratum (AS) context on the network device side, nor is there an RRC connection. The mobility of the terminal device is implemented based on cell selection and reselection. The paging of the terminal device is initiated by the core network (CN), and its paging area is configured by the CN. For the RRC_INACTIVE state, there is a connection between CN and NR, the UE AS context exists on a certain base station, the mobility of the terminal device is implemented based on cell selection and reselection, the paging of the terminal device is triggered by the radio access network (RAN), and its paging area is managed by the RAN. The network device knows that the location of the terminal device is based on the paging area level of the RAN.

[0105] In addition, the terminal device can switch or transition between various RRC states. For example, a UE in the RRC_CONNECTED state can enter the RRC_IDLE state by releasing the RRC connection; a UE in the RRC_IDLE state can enter the RRC_CONNECTED state by establishing an RRC connection; a UE in the RRC_CONNECTED state can enter the RRC_INACTIVE state by suspending (Release with Suspend) the RRC connection; a UE in the RRC_INACTIVE state can enter the RRC_CONNECTED state by resuming (Resume) the RRC connection, and of course, it can also enter the RRC_IDLE state by releasing the RRC connection.

[0106] In conjunction with the present application, the inactive state may include: RRC deactivated (RRC_INACTIVE) state and RRC idle (RRC_IDLE) state. The activated state may include: RRC connected (RRC_CONNECTED) state; in other words, the terminal device being in the inactive state means: the RRC state of the terminal device is in the RRC deactivated (RRC_INACTIVE) state or the RRC idle (RRC_IDLE) state; the terminal device being in the idle state means: the RRC state of the terminal device is in the RRC idle (RRC_IDLE) state.

[0107] In some embodiments, the first indication information is carried in a paging message, or the indication information is carried in a system message after the change, or the first indication information indicates through a specific downlink signal that the target cell will enter the energy-saving state.

[0108] In other words, the terminal device can indicate that the target cell will enter the energy-saving state through the first indication information carried in the paging message, thereby triggering the terminal device to perform switching of the service cell or switching of the resident cell; or, the terminal device can indicate that the target cell will enter the energy-saving state through the first indication information carried in the changed system message, thereby triggering the terminal device to perform switching of the service cell or switching of the resident cell; or, the terminal device can indicate that the target cell will enter the energy-saving state through a specific downlink signal, thereby triggering the terminal device to perform switching of the service cell or switching of the resident cell.

[0109] Exemplarily, the paging message may be a message sent by a paging device.

[0110] The paging device may be a network device or a core network device for providing the target cell. For example, if the terminal device is in a connected state or a deactivated state, the paging device may be a network device for providing the target cell; if the terminal device is in an idle state, the paging device may be a core network device. The paging device may also be referred to as a paging system. The paging message sent by the network device for providing the target cell may be downlink control information (DCI). The paging message sent by the core network device may be referred to as a CN paging message.

[0111] Exemplarily, the system message may be referred to as a broadcast message or system information (SI).

For example, the dedicated system message may be a dedicated SIB.

[0114] Exemplarily, if the first indication information is carried in the changed system message, the first indication information may be carried in an existing system message; that is, the changed system message includes the existing system message, and some fields in the existing system message carry the first indication information. For example, the existing system message may be an existing SIB.

[0115] Exemplarily, the specific downlink signal may include a channel scrambled by a specific Radio Network Temporary Identifier (RNTI).

[0116] Exemplarily, the specific downlink signal may be a specific downlink reference signal. The downlink reference signal includes, but is not limited to, a synchronization signal and / or a physical broadcast channel block (Synchronization Signal / PBCH Block, SSB), a channel state information reference signal (CSI-RS), or a downlink demodulation reference signal (DMRS). The downlink DMRS may be used for demodulation of a downlink channel.

[0117] In some embodiments, when the indication information is carried in a post-change system message, the method 210 may further include:

[0118] The terminal device receives the second indication information sent by the target cell, where the second indication information is used to instruct the terminal device to receive the changed system message.

[0119] In other words, the terminal device receives the second indication information sent by the target cell.

[0120] In other words, the terminal device receives the second indication information sent by the network device through the target cell.

[0121] Exemplarily, after the terminal device receives the second indication information, the second indication information is used to indicate that the system message sent by the target cell has changed; the second indication information can also be used to trigger the terminal device to receive the changed system message, and then, after the terminal device receives the changed system message, it can obtain the first indication information carried in the changed system message.

[0122] Exemplarily, the second indication information may be carried in a paging message, and the paging message may be a message sent by a paging device.

[0123] In other words, the paging device first sends the second indication information to the terminal device through a paging message, and then the network device used to provide the target cell can send the first indication information to the terminal device through the changed system message. The paging device can be a network device or a core network device used to provide the target cell. For example, if the terminal device is in a connected state or a deactivated state, the paging device can be a network device used to provide the target cell, and if the terminal device is in an idle state, the paging device can be a core network device. The paging device can also be called a paging system. The paging message sent by the network device used to provide the target cell can be downlink control information (DCI).

[0127] The time information is used to indicate the time when the target cell enters the energy-saving state.

[0128] Exemplarily, the information for indicating the frequency at which the terminal device preferentially resides may be: information for indicating the frequency point at which the terminal device preferentially resides, or information for indicating the frequency band at which the terminal device preferentially resides, or information for indicating the frequency layer at which the terminal device preferentially resides.

[0129] Exemplarily, the duration information may be the number of time units, and the time unit may be: a frame, a subframe, a time slot or a symbol.

[0130] Exemplarily, the duration information may be an absolute duration, for example, the duration information may also be a duration in seconds (s) or a duration in milliseconds (ms).

[0131] Exemplarily, when the first indication information includes the information for indicating the frequency on which the terminal device preferentially resides, when the terminal device performs cell reselection, the terminal device preferentially resides on the indicated frequency.

[0132] Exemplarily, if the first indication information includes the duration information, the target cell enters the energy-saving state after the terminal device receives the first indication information for a period of time indicated by the duration information; if the first indication information includes the moment information, the target cell enters the energy-saving state at the moment indicated by the moment information.

[0133] In some embodiments, the time information is used to indicate the target time unit, and the time when the target cell enters the energy-saving state is the start time or the end time of the target time unit.

[0134] In other words, the time information may be used to indicate that the time when the target cell enters the energy-saving state is the start time or the end time of the target time unit.

[0135] Exemplarily, when the target time unit is a system frame, the time information may be a system frame number (SFN), to indicate that the moment when the target cell enters the energy-saving state is the starting position or the ending position of the system frame identified by the SFN indicated by the time information.

[0136] Exemplarily, when the target time unit is a subframe, the moment information may be an index of the subframe, to indicate that the moment when the target cell enters the energy-saving state is the starting position or the ending position of the subframe identified by the index indicated by the moment information.

[0137] In some embodiments, the coverage type cell where the target cell is located is the service cell of the terminal device, or the target cell is a capacity type cell under the service cell of the terminal device.

[0138] For example, in network deployment, to meet user mobility and throughput requirements, coverage cells and capacity cells can be deployed jointly. Coverage cells are used to meet coverage requirements, while capacity cells are used in areas with a large number of users, such as urban areas, to share traffic and improve network capacity. Capacity cells are the target cells involved in the embodiments of this application, that is, capacity cells can be in an energy-saving state.

[0139] It is worth noting that the target cell involved in this application can spontaneously enter the energy-saving state. For example, when the business volume of the target cell is less than a preset threshold or there is no business volume, it can autonomously enter the energy-saving state, or it can enter the energy-saving state by negotiating with the neighboring cells of the target cell. This application does not make specific restrictions on this.

[0140] The above text, in combination with Figure 2, describes in detail the network energy-saving method provided in an embodiment of the present application from the perspective of the interaction between the terminal device and the target cell. The following text, in combination with Figure 3, describes the network energy-saving method provided in an embodiment of the present application from the perspective of the interaction between the network device used to provide the target cell and the network device used to provide the service cell of the terminal device.

[0141] Figure 3 is a schematic flow chart of the network energy-saving method 220 provided in an embodiment of the present application. The network energy-saving method 220 can be interactively executed by a network device for providing a service cell for a terminal device and a network device for providing a target cell. For example, the network device for providing the target cell and / or the network device for providing the service cell of the terminal device can be the access network device shown in Figure 1. Of course, the network energy-saving method 210 can also be understood as a method interactively executed by the service cell and the target cell, and this application does not limit this. In addition, it is worth noting that in an embodiment of the present application, the network device for providing the target cell and the network device for providing the service cell can be the same access network device or different access network devices, and this application does not specifically limit this.

[0142] As shown in FIG3 , the network energy saving method 220 may include:

[0143] S221, the target cell sends the configuration information of the target cell to the serving cell of the terminal device. In other words, the network device for providing the target cell sends the configuration information of the target cell to the network device for providing the serving cell.

[0144] Exemplarily, the target cell is a cell that can be in an energy-saving state.

[0145] It is worth noting that the term "wake up" involved in this application can also be equivalently replaced by "activation", "enablement" or terms with similar meanings, the term "sleep" can also be equivalently replaced by "deactivation", "disenablement" or terms with similar meanings, the term "energy-saving state" can also be equivalently replaced by "normal state," "deactivation state," "disenablement state," "non-activated state," "non-enabled state" or terms with similar meanings, the state of the target cell after activation can also be called "non-energy-saving state," "activation state," "enablement state" or terms with similar meanings, and this application does not make specific restrictions on this.

[0146] In some embodiments, the configuration information of the target cell includes at least one of the following:

[0147] Information used to indicate the frequency of the target cell;

[0148] Information used to indicate slices supported by the target cell;

[0149] System information of the target cell;

[0150] Information configured for a wake-up request for waking up the target cell;

[0151] a timing offset between the serving cell and the target cell;

[0152] Information used to identify whether the cell is close to the target cell.

[0153] In this embodiment, for the target cell that can be in an energy-saving state, by sending the configuration information of the target cell to the serving cell, it can not only ensure that the serving cell knows the status of the target cell in a timely manner, but also avoid the situation where communication failure occurs when the service cell does not know the actual status of the target cell and uses the target cell to share the traffic of the serving cell, thereby improving the communication performance.

[0154] In addition, after obtaining the configuration information of the target cell, the serving cell may also forward the configuration information of the target cell to the terminal device under the serving cell, so that the terminal device triggers the wake-up process of the target cell based on the configuration information of the target cell. For example, the terminal device may determine whether to trigger the wake-up process of the target cell based on the configuration information of the target cell, or the terminal device may determine whether to trigger the terminal device to send a wake-up request for waking up the target cell to the target cell or the serving cell based on the configuration information of the target cell.

[0155] Exemplarily, the information used to indicate the frequency of the target cell may be information specifically used to indicate the frequency, such as a new air interface frequency bandwidth indication (FreqBandIndicatorNR), or it may be information used to configure time-frequency resources, such as absolute frequency point A (absoluteFrequencyPointA), carrier offset (offsetToCarrier), subcarrier spacing (subcarrierSpacing), and location and bandwidth broadcast (locationAndBandwidthBroadcast).

[0156] Exemplarily, the system message of the target cell may be referred to as a broadcast message of the target cell or system information (SI) of the target cell.

[0157] Exemplarily, the system information of the target cell includes but is not limited to: a system information block (SIB), a master information block (MIB), or remaining system information (RMSI).

[0158] Exemplarily, the information configured for the wake-up request for waking up the target cell includes information used to generate the wake-up request and / or information used to configure time-frequency resources for the wake-up request, and the information used to generate the wake-up request includes at least one of the following: an identifier of the ZC sequence used by the wake-up request, an identifier of the preamble code used by the wake-up request, an identifier of the root sequence used to generate the ZC sequence or for generating the preamble code, and the time-frequency resources for the wake-up request are random access resources or time-frequency domain resources configured separately for the wake-up request.

[0159] In other words, after the terminal device obtains the information used to generate the wake-up request and the information used to configure the time-frequency resources for the wake-up request, it can generate the wake-up request based on the information used to generate the wake-up request, and send the wake-up request to the target cell or the serving cell based on the information used to configure the time-frequency resources for the wake-up request.

[0160] Exemplarily, the timing offset may be the number of time units, and the time unit may be: a frame, a subframe, a time slot or a symbol.

[0161] Exemplarily, the timing deviation may be an absolute duration, for example, the duration information may also be a duration in seconds (s) or a duration in milliseconds (ms).

[0162] Exemplarily, the information used to identify whether the target cell is close includes at least one of the following: an identifier of the beam of the serving cell, an identifier of the SSB of the serving cell, a threshold value corresponding to the identifier of the beam of the serving cell, and a threshold value corresponding to the identifier of the SSB of the serving cell.

[0163] In other words, after the terminal device obtains the information used to identify whether it is close to the target cell, it can determine whether it is close to the target cell based on the information used to identify whether it is close to the target cell, and when it is determined that it is close to the target cell, it can trigger the wake-up process of the target cell. For example, when the terminal device determines that it is close to the target cell, it sends a wake-up request to the target cell or the serving cell to wake up the target cell.

[0164] It should be understood that in the embodiments of the present application, the term "beam" can also be equivalently replaced by a spatial domain filter or can correspond to a spatial domain filter. For example, a transmit beam can be called a spatial domain transmission filter or can correspond to a spatial domain transmit filter, and a receive beam can be called a spatial domain receive filter or can correspond to a spatial domain receive filter. Of course, it can also be equivalently replaced with terms with similar meanings, and this application does not specifically limit this.

[0165] In some embodiments, the energy-saving state refers to: prohibiting the target cell from performing uplink reception or prohibiting the target cell from receiving uplink reception except the wake-up request, and prohibiting the target cell from performing downlink transmission.

[0166] In some embodiments, the energy-saving state refers to: prohibiting the target cell from performing uplink reception or prohibiting the target cell from receiving uplink reception except the wake-up request, and prohibiting the target cell from sending downlink transmission except a downlink discovery signal.

Of course, from the perspective of transmission of system messages, the downlink transmission may also include transmission of system information (SI), master information block (MIB) and system information block (SIB).

[0169] Exemplarily, when the target cell is in the energy-saving state, it may receive a wake-up request for waking up the target cell, which is sent by other cells or a coverage cell of the target cell.

[0170] Exemplarily, the target cell is prohibited from receiving signals and information from other cells in the energy-saving state.

[0171] Exemplarily, the target cell is prohibited from sending signals and information to other cells in the energy-saving state.

[0172] Exemplarily, the downlink discovery signal is used by the terminal device to discover the target cell.

[0173] It is worth noting that the embodiment of the present application does not limit the specific type of the downlink discovery signal. For example, the downlink discovery signal can be SSB, CSI-RS or other downlink signals. For example, the downlink reference signal can also be a reference signal specifically used to discover the target cell.

[0174] It should be understood that the embodiments of the present application may include physical channels or reference signals with the same name but different functions as those mentioned above, or may include physical channels or reference signals with different names but the same functions as those mentioned above, and the present application does not limit this. In addition, it should be understood that the terms "downlink" and "uplink" involved in the present application are used to indicate the transmission direction of signals or data, where "downlink" is used to indicate that the transmission direction of signals or data is the direction from the site to the user equipment of the cell, and "uplink" is used to indicate that the transmission direction of signals or data is the direction from the user equipment of the cell to the site.

[0175] In some embodiments, the coverage type cell where the target cell is located is the service cell of the terminal device, or the target cell is a capacity type cell under the service cell of the terminal device.

[0176] For example, in network deployment, to meet user mobility and throughput requirements, coverage cells and capacity cells can be deployed jointly. Coverage cells are used to meet coverage requirements, while capacity cells are used in areas with a large number of users, such as urban areas, to share traffic and improve network capacity. Capacity cells are the target cells involved in the embodiments of this application, that is, capacity cells can be in an energy-saving state.

[0177] The above describes in detail the network energy saving method provided by the embodiment of the present application from the perspective of target cell sleep in combination with Figures 2 and 3. The following will describe the cell wake-up method provided by the embodiment of the present application from the perspective of waking up the target cell in combination with Figures 4 to 6.

[0178] FIG4 is a schematic flow chart of a cell wake-up method 310 provided in an embodiment of the present application. The cell wake-up method 310 can be interactively executed by a terminal device and a network device for providing a target cell (or a network device for providing a serving cell for the terminal device). For example, the cell wake-up method 310 can be interactively executed by the terminal device shown in FIG1 and the access network device shown in FIG1. ​​Of course, the cell wake-up method 310 can also be understood as a method interactively executed by a terminal device and the target cell (or the serving cell), and this application does not limit this.

[0179] As shown in FIG3 , the cell wake-up method 310 may include:

[0180] S311 : Send a wake-up request, where the wake-up request is used to request to wake up a target cell in an energy-saving state.

[0181] In an embodiment of the present application, the target cell is awakened by sending a wake-up request by the terminal device. This can reduce the energy consumption of the network equipment used to provide the target cell, and wake up the target cell in real time by triggering the terminal device, thereby improving the flexibility of the target cell.

[0182] It is worth noting that the term "wake up" involved in this application can also be equivalently replaced by "activation", "enablement" or terms with similar meanings, the term "sleep" can also be equivalently replaced by "deactivation", "disenablement" or terms with similar meanings, the term "energy-saving state" can also be equivalently replaced by "normal state," "deactivation state," "disenablement state," "non-activated state," "non-enabled state" or terms with similar meanings, the state of the target cell after activation can also be called "non-energy-saving state," "activation state," "enablement state" or terms with similar meanings, and this application does not make specific restrictions on this.

[0183] In some embodiments, the energy-saving state refers to: prohibiting the target cell from performing uplink reception or prohibiting the target cell from receiving uplink reception except for a wake-up request for waking up the target cell, and prohibiting the target cell from performing downlink transmission.

[0184] In some embodiments, the energy-saving state refers to: prohibiting the target cell from performing uplink reception or prohibiting the target cell from receiving uplink reception except for a wake-up request for waking up the target cell, and prohibiting the target cell from sending downlink transmission except for a downlink discovery signal.

[0185] Exemplarily, the uplink reception may be reception of an uplink channel or an uplink signal. The uplink channel may include a physical random access channel (PRACH), a physical uplink control channel (PUCCH), a physical uplink shared channel (PUSCH), etc. The uplink reference signal may include an uplink demodulation reference signal (DMRS), a sounding reference signal (SRS), a phase tracking reference signal (PT-RS), etc. Among them, the uplink DMRS can be used for demodulation of the uplink channel, the SRS can be used for measurement of the uplink channel, synchronization or phase tracking on the uplink time and frequency, and the PT-RS can also be used for measurement of the uplink channel, synchronization or phase tracking on the uplink time and frequency.

[0186] Exemplarily, the downlink transmission may be the transmission of a downlink channel or a downlink signal. The downlink channel may include a physical downlink control channel (PDCCH), a physical downlink shared channel (PDSCH), a paging control channel (PCCH), a physical broadcast channel (PBCH), a paging channel (PCH), a primary common control physical channel (P-CCPCH), etc. The downlink reference signal may include: a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a synchronization signal and / or a physical broadcast channel block (SSB), a channel state information reference signal (CSI-RS) or a downlink demodulation reference signal (DMRS), etc., wherein the downlink DMRS can be used for demodulation of the downlink channel. Of course, from the perspective of transmission of system messages, the downlink transmission may also include transmission of system information (SI), master information block (MIB) and system information block (SIB).

[0187] Exemplarily, when the target cell is in the energy-saving state, it may receive a wake-up request for waking up the target cell, which is sent by other cells or a coverage cell of the target cell.

[0188] Exemplarily, the target cell is prohibited from receiving signals and information from other cells in the energy-saving state.

[0189] Exemplarily, the target cell is prohibited from sending signals and information to other cells in the energy-saving state.

[0190] Exemplarily, the downlink discovery signal is used by the terminal device to discover the target cell.

[0191] It is worth noting that the embodiment of the present application does not limit the specific type of the downlink discovery signal. For example, the downlink discovery signal can be SSB, CSI-RS or other downlink signals. For example, the downlink reference signal can also be a reference signal specifically used to discover the target cell.

[0192] It should be understood that the embodiments of the present application may include physical channels or reference signals with the same name but different functions as those mentioned above, or may include physical channels or reference signals with different names but the same functions as those mentioned above, and the present application does not limit this. In addition, it should be understood that the terms "downlink" and "uplink" involved in the present application are used to indicate the transmission direction of signals or data, where "downlink" is used to indicate that the transmission direction of signals or data is the direction from the site to the user equipment of the cell, and "uplink" is used to indicate that the transmission direction of signals or data is the direction from the user equipment of the cell to the site.

[0193] In some embodiments, the S311 may include:

[0194] The terminal device sends the wake-up request to the target cell.

[0195] In other words, the terminal device sends the wake-up request to the network device used to provide the target cell.

[0196] In other words, the terminal device sends the wake-up request to the network device through the target cell.

[0197] For example, as shown in FIG5 , the method 310 may further include:

[0198] S312: The network device for providing the target cell wakes up the target cell based on the wake-up request.

[0199] Exemplarily, the network device for providing the target cell may directly wake up the target cell after receiving the wake-up request.

[0200] In some embodiments, the method 310 may further include:

[0201] Determine whether to wake up the target cell.

[0202] Exemplarily, the network device for providing the target cell determines whether to wake up the target cell after receiving the wake-up request, and wakes up the target cell when it is determined to wake up the target cell.

[0203] In some embodiments, the network device for providing the target cell may determine whether to wake up the target cell based on at least one of the following:

[0204] The deployment location of the target cell, the time when the wake-up request is received, and the time period in which the wake-up request is received.

[0205] It is worth noting that in mobile communication networks, the distribution of traffic varies over time. For example, traffic may be less frequent at night and more frequent during the day, with even less traffic occurring around midnight. Furthermore, traffic distribution is also related to geographic location. For example, during the day, locations with many office buildings tend to have a high volume of users, but at night, there are almost no users. Urban or residential areas, on the other hand, experience low traffic during the daytime working hours, but may experience higher traffic at night. In view of this, in embodiments of the present application, whether to hibernate or awaken the target cell can be determined based on traffic volume. Furthermore, since the target cell is in an energy-saving state and does not know whether the current traffic volume is high or low, factors such as the target cell's deployment location, the time of receipt of the wake-up request, and the time period in which the wake-up request is received can reflect the serving cell's traffic volume. Therefore, by considering factors such as the target cell's deployment location, the time of receipt of the wake-up request, and the time period in which the wake-up request is received to determine whether to awaken the target cell, the target cell's network deployment can dynamically adjust its state based on changes in traffic volume, for example, dynamically awakening or dormant the target cell or determining whether to awaken the target cell, thereby achieving network energy conservation.

[0206] In some embodiments, the wake-up request wakes up the target cell via a ZC sequence or a preamble request.

[0207] Exemplarily, the ZC sequence used in the wake-up request may be any ZC sequence that can be used by the target cell.

[0208] Exemplarily, the ZC sequence used by the wake-up request may be a ZC sequence reserved for the wake-up request among ZC sequences available to the target cell, wherein the ZC sequence reserved for the wake-up request may be one or more ZC sequences.

[0209] Exemplarily, the preamble code used by the wake-up request may be any preamble code that can be used by the target cell.

[0210] Exemplarily, the preamble used by the wake-up request may be a preamble reserved for the wake-up request among preambles available for the target cell, wherein the preamble reserved for the wake-up request may be one or more preambles.

[0211] Exemplarily, the terminal device sends a ZC sequence or a preamble to the target cell, where the ZC sequence or the preamble is used to request waking up the target cell. In other words, the ZC sequence or the preamble is used to trigger a network device providing the target cell to wake up the target cell.

[0212] In some embodiments, the ZC sequence used in the wake-up request is different from the ZC sequence used in the target cell, or the root sequence used to generate the ZC sequence used in the wake-up request is different from the root sequence used in the neighboring cell of the target cell.

[0213] In this embodiment, by distinguishing the ZC sequence used by the wake-up request from the ZC sequence used by the target cell, or by distinguishing the root sequence of the ZC sequence used by the wake-up request from the root sequence of the ZC sequence used by the target cell, it is possible to ensure that the cell using the ZC sequence used by the wake-up request or the root sequence of the ZC sequence used by the wake-up request (i.e., the target cell) knows that the wake-up request is a request sent by the terminal device to itself, so that the terminal device's sending of the wake-up request and the target cell's reception of the wake-up request are consistent, thereby improving the wake-up success rate.

[0214] In some embodiments, the method 310 may further include:

[0215] The network device used to provide the target cell sends notification information to a neighboring cell of the target cell, where the notification information is used to indicate that the target cell has been awakened.

[0216] In this embodiment, the network device used to provide the target cell can ensure that the neighboring cells of the target cell can know the status of the target cell in a timely manner by sending the notification information to the neighboring cells of the target cell, and then use the target cell to share the business volume of the serving cell when communication failure occurs, thereby improving communication performance.

[0217] In some embodiments, the method 310 may further include:

[0218] The network device used to provide the target cell sends a downlink discovery signal.

[0219] Exemplarily, after the target cell enters the energy-saving state, it sends a downlink discovery signal to the terminal device. For example, after the target cell enters the energy-saving state, it periodically sends a downlink discovery signal. Accordingly, when the terminal device is within the coverage area of ​​the target cell, it can discover the target cell through the downlink discovery signal.

[0220] Exemplarily, if the energy-saving state indicates that the target cell is prohibited from sending downlink transmissions other than downlink discovery signals, the target cell sends the downlink reference signal to the terminal device.

[0221] In some embodiments, the terminal device is in a connected state, and S310 may include:

[0222] Send a wake-up request to the serving cell of the terminal device.

[0223] In other words, the terminal device sends the wake-up request to the network device used to provide the serving cell.

[0224] In other words, the terminal device sends the wake-up request to the network device through the serving cell.

[0225] For example, as shown in FIG3 , the method 310 may further include:

[0226] S313: The network device for providing the serving cell forwards the wake-up request to the network device for providing the target cell.

[0227] In other words, after receiving the wake-up request sent by the terminal device, the network device used to provide the service cell forwards the wake-up request to the network device used to provide the target cell.

[0228] Exemplarily, after receiving the wake-up request, the network device for providing the serving cell may directly forward the wake-up request to the network device for providing the target cell, so that the network device for providing the target cell wakes up the target cell.

[0229] In some embodiments, the method 310 may further include:

[0230] The network device for providing the serving cell determines whether to forward the wake-up request to the network device for providing the target cell.

[0231] Exemplarily, after receiving the wake-up request, the network device for providing the service cell determines whether to forward the wake-up request to the network device for providing the target cell, and forwards the wake-up request to the network device for providing the target cell when determining to forward the wake-up request.

[0232] In some embodiments, the network device for providing the serving cell determines whether to forward the wake-up request to the target cell based on at least one of the following:

[0233] The traffic volume of the serving cell, the deployment location of the serving cell, the deployment location of the target cell, the time when the wake-up request is received, and the time period in which the wake-up request is received.

[0234] It is worth noting that in mobile communication networks, the distribution of services varies with time of day. For example, there may be less service at night and more service during the day, with even less service around midnight. Furthermore, the distribution of services is also related to geographic location. For example, during the day, locations with many office buildings tend to have a large number of users, but at night, there are almost no users. Urban or residential areas, on the other hand, have very little service during the daytime working hours, but may have more service at night. In view of this, in an embodiment of the present application, the network device used to provide the serving cell can determine whether to hibernate or wake up the target cell based on the amount of service traffic. Factors such as the target cell's deployment location, the time of receipt of the wake-up request, and the time period in which the wake-up request is received can reflect the serving cell's service traffic. Therefore, by considering factors such as the target cell's deployment location, the time of receipt of the wake-up request, and the time period in which the wake-up request is received to determine whether to forward the wake-up request to the target cell, the target cell's network deployment can dynamically adjust its state based on changes in service traffic, such as dynamically waking or hibernating the target cell or determining whether to wake it up, thereby achieving network energy conservation.

[0235] Of course, since the serving cell can obtain the service volume of the serving cell, in other alternative embodiments, the serving cell can also determine whether to forward the wake-up request to the target cell based on the service volume of the serving cell, and this application does not make specific limitations on this.

[0236] In some embodiments, the wake-up request carries identification information of the target cell.

[0237] Exemplarily, the identification information is used to enable the network device providing the serving cell to determine or identify the network device providing the target cell.

[0238] In some embodiments, the identification information includes at least one of the following: a physical cell identifier (PCI) of the target cell, a frequency of the target cell, and a cell identifier of the target cell.

[0239] Exemplarily, the identification information includes the PCI of the target cell and the frequency of the target cell.

[0240] Exemplarily, the identification information includes a cell identification of the target cell.

[0241] Exemplarily, the cell identifier of the target cell is used to uniquely identify the target cell.

[0242] Exemplarily, the PCI of the target cell is used to distinguish or identify the wireless signal of the target cell. For example, the PCI used by other cells within the coverage of the target cell is different from the PCI used by the target cell.

[0243] In some embodiments, the method 310 may further include:

[0244] The network device used to provide the serving cell receives notification information sent by the target cell, where the notification information is used to indicate that the target cell has been awakened.

[0245] In this embodiment, the network device used to provide the service cell can ensure that the service cell can know the status of the target cell in a timely manner by receiving the notification information sent by the target cell, and then use the target cell to share the business volume of the service cell when communication failure occurs, thereby improving communication performance.

[0246] In some embodiments, the S310 may include:

[0247] When the terminal device approaches the target cell and the terminal device desires to wake up the target cell, the wake-up request is sent.

[0248] Exemplarily, the terminal device being close to the target cell means that the terminal device is located within the coverage of the target cell.

[0249] Exemplarily, the terminal device being close to the target cell means that the terminal device is close to the coverage of the target cell, for example, the terminal device is close to the edge of the coverage of the target cell.

[0250] Exemplarily, the terminal device expecting to wake up the target cell means that after the target cell wakes up, the terminal device expects to use the target cell to transmit and / or receive data.

[0251] In some embodiments, the method 310 may further include:

[0252] When the beam quality of the service cell of the terminal device is greater than or equal to a first threshold value, and / or when the signal quality of the synchronization signal and / or physical broadcast channel block (Synchronization Signal / PBCH Block, SSB) of the service cell is greater than or equal to a second threshold value, it is determined that the terminal device is close to the target cell.

[0253] Exemplarily, the target cell is a cell in the direction of the beam used by the serving cell.

[0254] Exemplarily, the target cell is a cell in the direction of the SSB used by the serving cell.

[0255] Exemplarily, the first threshold value may be configured by the serving cell, may be determined by the terminal device, may be predefined, or may even be determined by negotiation between the serving cell and the terminal device. Similarly, the second threshold value may be configured by the serving cell, may be determined by the terminal device, may be predefined, or may even be determined by negotiation between the serving cell and the terminal device.

[0256] Exemplarily, the beam quality includes but is not limited to: Reference Signal Receiving Power (RSRP) or Reference Signal Receiving Quality (RSRQ).

[0257] Exemplarily, the signal quality of the SSB of the serving cell includes but is not limited to: RSRP or RSRQ.

[0258] In this embodiment, if the beam quality of the service cell of the terminal device is greater than or equal to the first threshold value, it means that the terminal device is in the beam direction of the service cell. If the signal quality of the SSB of the service cell is greater than or equal to the second threshold value, it means that the terminal device is in the direction of the SSB used by the service cell. At this time, it is directly determined that the terminal device is close to the target cell, which can not only realize the judgment of whether the terminal device is close to the target cell, but also reduce its complexity, thereby improving the performance of the terminal device.

[0259] Of course, in other alternative embodiments, when the beam quality of the service cell of the terminal device is within the beam quality range, and / or when the signal quality of the SSB of the service cell is within the signal quality range, it can also be determined that the terminal device is close to the target cell, and even the terminal device can use other methods to determine whether the terminal device is close to the target cell. This application does not make specific limitations on this.

[0260] For example, the terminal device may determine whether it is close to the target cell based on the distance of the terminal device relative to the network device used to provide the target cell. In one implementation, if the distance of the terminal device relative to the network device used to provide the target cell is less than a preset threshold, it is determined that the terminal device is close to the target cell; otherwise, it is determined that the terminal device is not close to the target cell; in another implementation, if the distance of the terminal device relative to the network device used to provide the target cell is within a preset range, it is determined that the terminal device is close to the target cell; otherwise, it is determined that the terminal device is not close to the target cell. Optionally, the preset threshold or the preset range may be determined based on the radius of the coverage range of the target cell. Optionally, the distance of the terminal device relative to the network device used to provide the target cell may be determined based on the position of the network device used to provide the target cell relative to the network device used to provide the target cell, and the position of the terminal device relative to the network device used to provide the serving cell.

[0261] For another example, in the direction of the beam used when the serving cell sends information to the target cell, the terminal device may determine whether it is close to the target cell based on the distance of the terminal device relative to the network device used to provide the serving cell. In one implementation, if the distance of the terminal device relative to the network device used to provide the serving cell is greater than a preset threshold, it is determined that the terminal device is close to the target cell; otherwise, it is determined that the terminal device is not close to the target cell; in another implementation, if the distance of the terminal device relative to the network device used to provide the serving cell is within a preset range, it is determined that the terminal device is close to the target cell; otherwise, it is determined that the terminal device is not close to the target cell. Optionally, the preset threshold or the preset range can be determined based on the coverage of the serving cell, the coverage of the target cell, and the position of the serving cell relative to the target cell.

[0262] In some embodiments, the method 310 may further include:

[0263] When the frequency priority of the target cell is greater than the frequency priority of the serving cell of the terminal device, and / or when the slice supported by the target cell is the slice expected by the terminal device, it is determined that the terminal device expects to wake up the target cell.

[0264] Exemplarily, when the priority of the frequency point (frequency band or frequency layer) of the target cell is greater than the priority of the frequency point (frequency band or frequency layer) of the serving cell, it is determined that the terminal device expects to wake up the target cell. In other words, if the terminal device expects to transmit and / or receive data on the frequency point (frequency band or frequency layer) of the target cell, it is determined that the terminal device expects to wake up the target cell.

[0265] Exemplarily, if the terminal device expects to transmit and / or receive data on a slice supported by the target cell, it is determined that the terminal device expects to wake up the target cell. In other words, when the priority of the slice supported by the target cell is greater than the priority of the slice supported by the serving cell, it is determined that the terminal device expects to wake up the target cell.

[0266] In some embodiments, the S310 may include:

[0267] The terminal device receives a downlink discovery signal sent by the target cell;

[0268] When the terminal device approaches the target cell, the quality of the downlink discovery signal meets the wake-up requirement, and the target cell and the terminal device expect to wake up the target cell, the wake-up request is sent.

[0269] Exemplarily, the quality of the downlink discovery signal meeting the wake-up requirement means that the quality of the downlink discovery reference signal meets the quality requirement of the terminal device performing data transmission and / or data reception by utilizing the target cell.

[0270] In some embodiments, the method 310 may further include:

[0271] When the quality of the downlink discovery signal is greater than or equal to a third threshold value, the terminal device determines that the quality of the downlink discovery signal meets the wake-up requirement.

[0272] Exemplarily, the third threshold value may be configured by the serving cell, may be determined by the terminal device, may be predefined, or may even be determined through negotiation between the serving cell and the terminal device.

[0273] Exemplarily, the third threshold value may be a threshold value involved in cell selection or cell reselection.

[0274] Exemplarily, the quality of the downlink discovery signal includes but is not limited to: RSRP or RSRQ.

[0275] Of course, in other alternative embodiments, the quality of the downlink reference signal meeting the wake-up requirement may also mean that the quality of the downlink reference signal is within a certain quality range, which is not specifically limited in this application.

[0276] It is worth noting that if the terminal device sends the wake-up request when the terminal device is close to the target cell and the terminal device expects to wake up the target cell, the energy-saving state involved in this application may refer to prohibiting the target cell from performing downlink transmission, or may refer to prohibiting the target cell from sending downlink transmission other than the downlink discovery signal; if the terminal device sends the wake-up request when the terminal device is close to the target cell, the quality of the downlink discovery signal meets the wake-up requirements, and the target cell and the terminal device expect to wake up the target cell, the energy-saving state involved in this application refers to prohibiting the target cell from sending downlink transmission other than the downlink discovery signal.

[0277] In some embodiments, the method 310 may further include:

[0278] After sending the wake-up request, the terminal device performs a cell selection operation and / or a cell reselection operation at an interval of a first time length.

[0279] Exemplarily, the first duration may include the transmission duration of the wake-up request and / or the wake-up duration when the network device used to provide the target cell wakes up the target cell. Optionally, when the terminal device sends the wake-up request to the target cell through the serving cell, the transmission duration includes the duration occupied by the wake-up request when being transmitted between the terminal device and the serving cell and the duration occupied by the wake-up request when being transmitted between the serving cell and the target cell. The transmission duration may even include the forwarding duration when the serving cell forwards the wake-up request.

[0280] In some embodiments, after sending the wake-up request, the terminal device starts a timer with the first duration; if the timer times out, a cell selection operation and / or a cell reselection operation is performed.

[0281] Exemplarily, the terminal device starts a timer with the first duration at the end moment of sending the wake-up request; if the timer times out, a cell selection operation and / or a cell reselection operation is performed. Of course, in other alternative embodiments, the terminal device may also start a timer with the first duration at the start moment of sending the wake-up request; if the timer times out, a cell selection operation and / or a cell reselection operation is performed. At this time, in addition to including the transmission duration of the wake-up request and / or the wake-up duration when the network device used to provide the target cell wakes up the target cell, the first duration may also include the duration taken by the terminal device to send the wake-up request.

[0282] In some embodiments, the first duration is determined by the terminal device, or the first duration is a duration configured by the network device, or the first duration is a predefined duration, or the first duration depends on the implementation of the terminal device.

[0283] Exemplarily, the first duration may be configured by sending a timer parameter to the terminal device.

[0284] Exemplarily, the first duration is the duration configured by the network device, which may be the duration configured by the serving cell, or the duration configured by the target cell and forwarded by the serving cell to the terminal device.

[0285] In some embodiments, after sending the wake-up request, the terminal device receives the synchronization signal and system message sent by the target cell at an interval of a first time length; and performs a cell selection operation and / or a cell reselection operation based on the synchronization signal and the system message.

[0286] Exemplarily, the synchronization signal includes but is not limited to: a primary synchronization signal (PSS) and a secondary synchronization signal (SSS).

[0287] Exemplarily, the system message includes but is not limited to: System Information (SI), Master Information Block (MIB), System Information Block (SIB), and Remaining System Information (RMSI).

[0288] Exemplarily, after sending the wake-up request, the terminal device starts a timer with the first duration; if the timer times out, it receives the synchronization signal and system message sent by the target cell; and based on the synchronization signal and the system message, it performs a cell selection operation and / or a cell reselection operation.

[0289] Of course, in other alternative embodiments, if there is a paging message of the terminal device, the terminal device may further send the paging message to the terminal device after sending the wake-up request. For example, after sending the wake-up request, the paging message, the synchronization signal and the system message sent by the target cell are received simultaneously at intervals of a first duration. In addition, after sending the wake-up request, the terminal device may also directly start receiving synchronization signals and system messages, and start a timer with the first duration after sending the wake-up request. In this case, if the timer times out, a cell selection operation and / or a cell reselection operation is performed. In other words, a timer with the first duration may be used only to trigger a cell selection operation and / or a cell reselection operation, or may be used to trigger a cell selection operation and / or a cell reselection operation on the basis of being used to trigger the terminal device to receive synchronization signals and system messages.

[0290] In some embodiments, the method 310 may further include:

[0291] The terminal device receives the configuration information of the target cell sent by the serving cell of the terminal device, where the configuration information of the target cell includes at least one of the following:

[0292] Information used to indicate the frequency of the target cell;

[0293] Information used to indicate slices supported by the target cell;

[0294] System information of the target cell;

[0295] Configuration information of the wake-up request;

[0296] a timing offset between the serving cell and the target cell;

[0297] Configuration information used to identify whether the cell is close to the target cell.

[0298] Exemplarily, the configuration information of the target cell is configuration information sent by the target cell to the serving cell when the target cell enters an energy-saving state.

[0299] In this embodiment, for a target cell that can be in an energy-saving state, sending the configuration information of the target cell through the serving cell is beneficial for the terminal device to determine whether to trigger the wake-up process of the target cell, or is beneficial for the terminal device to determine whether to trigger the terminal device to send a wake-up request to the target cell or the serving cell for waking up the target cell. For example, the information indicating the frequency of the target cell and the information indicating the slices supported by the target cell in the configuration information of the target cell can be used by the terminal device to determine whether it is desired to activate the target cell; the configuration information for identifying whether it is close to the target cell in the configuration information of the target cell can be used by the terminal device to determine whether the terminal device is close to the target cell; the configuration information of the wake-up request in the configuration information of the target cell can be used by the terminal device to send the wake-up request.

[0300] Exemplarily, the information used to indicate the frequency of the target cell may be information specifically used to indicate the frequency, such as a new air interface frequency bandwidth indication (FreqBandIndicatorNR), or it may be information used to configure time-frequency resources, such as absolute frequency point A (absoluteFrequencyPointA), carrier offset (offsetToCarrier), subcarrier spacing (subcarrierSpacing), and location and bandwidth broadcast (locationAndBandwidthBroadcast).

[0301] Exemplarily, the system message of the target cell may be referred to as a broadcast message of the target cell or system information (SI) of the target cell.

[0302] Exemplarily, the system information of the target cell includes but is not limited to: a system information block (SIB), a master information block (MIB), or remaining system information (RMSI).

[0303] Exemplarily, the configuration information of the wake-up request includes information for generating the wake-up request and / or information for configuring time-frequency resources for the wake-up request, and the information for generating the wake-up request includes at least one of the following: an identifier of the ZC sequence used by the wake-up request, an identifier of the preamble code used by the wake-up request, an identifier of the root sequence used to generate the ZC sequence or for generating the preamble code, and the time-frequency resources for the wake-up request are random access resources or time-frequency domain resources configured separately for the wake-up request.

[0304] In other words, after the terminal device obtains the information used to generate the wake-up request and the information used to configure the time-frequency resources for the wake-up request, it can generate the wake-up request based on the information used to generate the wake-up request, and send the wake-up request to the target cell or the serving cell based on the information used to configure the time-frequency resources for the wake-up request.

[0305] Exemplarily, the timing offset may be the number of time units, and the time unit may be: a frame, a subframe, a time slot or a symbol.

[0306] Exemplarily, the timing deviation may be an absolute duration, for example, the duration information may also be a duration in seconds (s) or a duration in milliseconds (ms).

[0307] Exemplarily, the information used to identify whether the target cell is close includes at least one of the following: an identifier of the beam of the serving cell, an identifier of the SSB of the serving cell, a threshold value corresponding to the identifier of the beam of the serving cell, and a threshold value corresponding to the identifier of the SSB of the serving cell.

[0308] In other words, after the terminal device obtains the information used to identify whether it is close to the target cell, it can determine whether it is close to the target cell based on the information used to identify whether it is close to the target cell, and when it is determined that it is close to the target cell, it can trigger the wake-up process of the target cell. For example, when the terminal device determines that it is close to the target cell, it sends a wake-up request to the target cell or the serving cell to wake up the target cell.

[0309] Exemplarily, the threshold value corresponding to the identifier of the beam of the serving cell may be the first threshold value mentioned above.

[0310] Exemplarily, the threshold value corresponding to the identifier of the SSB of the serving cell may be the second threshold value mentioned above.

[0311] Of course, in other alternative embodiments, the configuration information of the target cell may also include information for determining whether the quality of the downlink discovery signal meets the wake-up requirements. For example, the information for determining whether the quality of the downlink discovery signal meets the wake-up requirements may be the third threshold value mentioned above.

[0312] In some embodiments, the coverage type cell where the target cell is located is the service cell of the terminal device, or the target cell is a capacity type cell under the service cell of the terminal device.

[0313] For example, in network deployment, to meet user mobility and throughput requirements, coverage cells and capacity cells can be deployed jointly. Coverage cells are used to meet coverage requirements, while capacity cells are used in areas with a large number of users, such as urban areas, to share traffic and improve network capacity. Capacity cells are the target cells involved in the embodiments of this application, that is, capacity cells can be in an energy-saving state.

[0314] The cell wake-up method is exemplarily described below in conjunction with the specific embodiments provided in this application.

[0315] Example 1:

[0316] In this embodiment, when the target cell is in an energy-saving state, the target cell is prohibited from performing uplink reception or is prohibited from receiving uplink reception other than a wake-up request for waking up the target cell, and is prohibited from performing downlink transmission. In this case, the terminal device wakes up the target cell by sending a wake-up request to the target cell.

[0317] FIG7 is a schematic flowchart of a method 320 for waking up a target cell by sending a wake-up request to the target cell in the absence of a downlink discovery signal, provided in an embodiment of the present application.

[0318] As shown in FIG7 , assuming that the dormant cells that intersect with the coverage of the serving cell of the terminal device include dormant cell 1 and dormant cell 2, the method for waking up dormant cell 2 is described below by taking dormant cell 2 as the target cell. The method 320 may include:

[0319] S321, the serving cell of the terminal device sends the configuration information of the target cell to the terminal device.

[0320] Exemplarily, the configuration information of the target cell includes at least one of the following:

[0321] Information used to indicate the frequency of the target cell;

[0322] Information used to indicate slices supported by the target cell;

[0323] System information of the target cell;

[0324] Configuration information of the wake-up request;

[0325] a timing offset between the serving cell and the target cell;

[0326] Configuration information used to identify whether the cell is close to the target cell.

[0327] It should be understood that the description of each information in the configuration information of the target cell can be found in the relevant description above, and to avoid repetition, it will not be repeated here.

[0328] S322, the terminal device sends a wake-up request to the target cell, where the wake-up request is used to request to wake up the target cell.

[0329] Exemplarily, the wake-up request wakes up the target cell via a ZC sequence or a preamble code request.

[0330] Exemplarily, a ZC sequence used in the wake-up request is different from a ZC sequence used in the target cell, or a root sequence used to generate the ZC sequence used in the wake-up request is different from a root sequence used in a neighboring cell of the target cell.

[0331] Exemplarily, when the terminal device is close to the target cell and the terminal device expects to wake up the target cell, the terminal device sends the wake-up request to the target cell. Optionally, when the beam quality of the serving cell of the terminal device is greater than or equal to a first threshold value, and / or when the signal quality of the synchronization signal and / or physical broadcast channel block (Synchronization Signal / PBCH Block, SSB) of the serving cell is greater than or equal to a second threshold value, the terminal device determines that the terminal device is close to the target cell. When the frequency priority of the target cell is greater than the frequency priority of the serving cell of the terminal device, and / or when the slice supported by the target cell is the slice expected by the terminal device, the terminal device determines that the terminal device expects to wake up the target cell.

[0332] Exemplarily, the configuration information of the wake-up request in the configuration information of the target cell includes information for generating the wake-up request and / or information for configuring time-frequency resources for the wake-up request, and the information for generating the wake-up request includes at least one of the following: an identifier of the ZC sequence used by the wake-up request, an identifier of the preamble code used by the wake-up request, an identifier of the root sequence used to generate the ZC sequence or for generating the preamble code, and the time-frequency resources for the wake-up request are random access resources or time-frequency domain resources configured separately for the wake-up request.

[0333] Exemplarily, the configuration information of the target cell used to identify whether the cell is close to the target cell may include: the first threshold value and the second threshold value.

[0334] S323, the target cell wakes up the target cell after receiving the wake-up request from the terminal device, that is, the target cell returns to a normal cell state or a non-energy-saving state.

[0335] Exemplarily, the target cell may directly wake up the target cell after receiving the wake-up request.

[0336] Exemplarily, after receiving the wake-up request, the target cell determines whether to wake up the target cell, and wakes up the target cell when it is determined to wake up the target cell.

[0337] Exemplarily, the target cell may determine whether to wake up the target cell based on at least one of the following:

[0338] The deployment location of the target cell, the time when the wake-up request is received, and the time period in which the wake-up request is received.

[0339] It is worth noting that in mobile communication networks, the distribution of traffic varies over time. For example, traffic may be less frequent at night and more frequent during the day, with even less traffic occurring around midnight. Furthermore, traffic distribution is also related to geographic location. For example, during the day, locations with many office buildings tend to have a high volume of users, but at night, there are almost no users. Urban or residential areas, on the other hand, experience low traffic during the daytime working hours, but may experience higher traffic at night. In view of this, in embodiments of the present application, whether to hibernate or awaken the target cell can be determined based on traffic volume. Furthermore, since the target cell is in an energy-saving state and does not know whether the current traffic volume is high or low, factors such as the target cell's deployment location, the time of receipt of the wake-up request, and the time period in which the wake-up request is received can reflect the serving cell's traffic volume. Therefore, by considering factors such as the target cell's deployment location, the time of receipt of the wake-up request, and the time period in which the wake-up request is received to determine whether to awaken the target cell, the target cell's network deployment can dynamically adjust its state based on changes in traffic volume, for example, dynamically awakening or dormant the target cell or determining whether to awaken the target cell, thereby achieving network energy conservation.

[0340] S324, the target cell sends a synchronization signal and system message, etc. to the terminal device.

[0341] Exemplarily, the synchronization signal includes but is not limited to: a primary synchronization signal (PSS) and a secondary synchronization signal (SSS).

[0342] Exemplarily, the system message includes but is not limited to: System Information (SI), Master Information Block (MIB), System Information Block (SIB), and Remaining System Information (RMSI).

[0343] Exemplarily, after sending the wake-up request, the terminal device starts a timer with the first duration; if the timer times out, it receives the synchronization signal and system message sent by the target cell; and based on the synchronization signal and the system message, it performs a cell selection operation and / or a cell reselection operation.

[0344] Of course, in other alternative embodiments, if there is a paging message of the terminal device, the terminal device may further send the paging message to the terminal device after sending the wake-up request. For example, after sending the wake-up request, the paging message, the synchronization signal and the system message sent by the target cell are received simultaneously at intervals of a first duration. In addition, after sending the wake-up request, the terminal device may also directly start receiving synchronization signals and system messages, and start a timer with the first duration after sending the wake-up request. In this case, if the timer times out, a cell selection operation and / or a cell reselection operation is performed. In other words, a timer with the first duration may be used only to trigger a cell selection operation and / or a cell reselection operation, or may be used to trigger a cell selection operation and / or a cell reselection operation on the basis of being used to trigger the terminal device to receive synchronization signals and system messages.

[0345] S325: The target cell sends notification information to the serving cell indicating that the target cell has been awakened.

[0346] In this embodiment, the target cell is awakened by sending a wake-up request by the terminal device to the target cell. This can reduce the energy consumption of the target cell and wake up the target cell in real time by triggering the terminal device, thereby improving the flexibility of the target cell. In addition, after the target cell is awakened, the target cell sends the notification information to the serving cell, ensuring that the serving cell can promptly know the status of the target cell. In addition, the target cell can be used to share the traffic of the serving cell in the event of a communication failure, thereby improving communication performance.

[0347] Example 2:

[0348] In this embodiment, when the target cell is in an energy-saving state, the target cell is prohibited from performing uplink reception or is prohibited from receiving uplink reception other than a wake-up request for waking up the target cell, and the target cell is prohibited from performing downlink transmission. In this case, if the RRC connection state of the terminal device is in an activated state, the terminal device can wake up the target cell by sending a wake-up request to the target cell through the serving cell of the terminal device.

[0349] FIG8 is a schematic flowchart of a method 330 for waking up a target cell by sending a wake-up request to a serving cell in the absence of a downlink discovery signal, provided in an embodiment of the present application.

[0350] As shown in FIG8 , assuming that the dormant cells that intersect with the coverage of the serving cell of the terminal device include dormant cell 1 and dormant cell 2, the method for waking up dormant cell 2 is described below by taking dormant cell 2 as the target cell. The method 330 may include:

[0351] S331, the serving cell of the terminal device sends the configuration information of the target cell to the terminal device.

[0352] Exemplarily, the configuration information of the target cell includes at least one of the following:

[0353] Information used to indicate the frequency of the target cell;

[0354] Information used to indicate slices supported by the target cell;

[0355] System information of the target cell;

[0356] Configuration information of the wake-up request;

[0357] a timing offset between the serving cell and the target cell;

[0358] Configuration information used to identify whether the cell is close to the target cell.

[0359] It should be understood that the description of each information in the configuration information of the target cell can be found in the relevant description above, and to avoid repetition, it will not be repeated here.

[0360] S332, the terminal device sends a wake-up request carrying the identification information of the target cell to the serving cell.

[0361] Exemplarily, the identification information includes the PCI of the target cell and the frequency of the target cell.

[0362] Exemplarily, the identification information includes a cell identification of the target cell.

[0363] Exemplarily, when the terminal device is close to the target cell and the terminal device expects to wake up the target cell, the terminal device sends the wake-up request to the target cell. Optionally, when the beam quality of the serving cell of the terminal device is greater than or equal to a first threshold value, and / or when the signal quality of the synchronization signal and / or physical broadcast channel block (Synchronization Signal / PBCH Block, SSB) of the serving cell is greater than or equal to a second threshold value, the terminal device determines that the terminal device is close to the target cell. When the frequency priority of the target cell is greater than the frequency priority of the serving cell of the terminal device, and / or when the slice supported by the target cell is the slice expected by the terminal device, the terminal device determines that the terminal device expects to wake up the target cell.

[0364] Exemplarily, the configuration information of the wake-up request in the configuration information of the target cell includes information for configuring time-frequency resources for the wake-up request, and the time-frequency resources for the wake-up request are random access resources or time-frequency domain resources configured separately for the wake-up request.

[0365] Exemplarily, the configuration information of the target cell used to identify whether the cell is close to the target cell may include: the first threshold value and the second threshold value.

[0366] S333: After receiving the wake-up request from the terminal device, the serving cell forwards the wake-up request to the target cell.

[0367] Exemplarily, after receiving the wake-up request, the serving cell may directly forward the wake-up request to the target cell.

[0368] Exemplarily, after receiving the wake-up request, the serving cell determines whether to forward the wake-up request to the target cell, and forwards the wake-up request to the target cell when determining to forward the wake-up request.

[0369] Exemplarily, the serving cell may determine whether to forward the wake-up request to the target cell based on at least one of the following:

[0370] The traffic volume of the serving cell, the deployment location of the serving cell, the deployment location of the target cell, the time when the wake-up request is received, and the time period in which the wake-up request is received.

[0371] It is worth noting that in a mobile communication network, the distribution of services varies with time. For example, there will be less service at night and more service during the day, especially at midnight. At the same time, the distribution of services is also related to the geographical area. For example, during the day, there will be a large number of users in geographical locations with many office buildings, but there will be almost no users at night. In urban or residential areas, there will be very little service during the daytime working hours, but there may be more service at night. In view of this, in an embodiment of the present application, the serving cell can determine whether to sleep or wake up the target cell based on the amount of service volume. Since the deployment location of the target cell, the time when the wake-up request is received, the time period in which the wake-up request is received, and other factors can reflect the service volume of the serving cell, therefore, by considering the deployment location of the target cell, the time when the wake-up request is received, the time period in which the wake-up request is received, and other factors to determine whether to forward the wake-up request to the target cell, the network deployment of the target cell can dynamically adjust its status according to changes in service volume, such as dynamically waking up or sleeping the target cell or determining whether to wake up the target cell, thereby achieving the purpose of network energy saving.

[0372] S334: After receiving the wake-up request forwarded by the serving cell, the target cell wakes up the target cell, that is, the target cell returns to a normal cell state or a non-energy-saving state.

[0373] Exemplarily, the target cell may directly wake up the target cell after receiving the wake-up request.

[0374] S335a: The target cell sends notification information to the serving cell indicating that the target cell has been awakened.

[0375] S335b, the target cell sends a synchronization signal and system message, etc. to the terminal device.

[0376] Exemplarily, the synchronization signal includes but is not limited to: a primary synchronization signal (PSS) and a secondary synchronization signal (SSS).

[0377] Exemplarily, the system message includes but is not limited to: System Information (SI), Master Information Block (MIB), System Information Block (SIB), and Remaining System Information (RMSI).

[0378] Exemplarily, after sending the wake-up request, the terminal device starts a timer with the first duration; if the timer times out, it receives the synchronization signal and system message sent by the target cell; and based on the synchronization signal and the system message, it performs a cell selection operation and / or a cell reselection operation.

[0379] Of course, in other alternative embodiments, if there is a paging message of the terminal device, the terminal device may further send the paging message to the terminal device after sending the wake-up request. For example, after sending the wake-up request, the paging message, the synchronization signal and the system message sent by the target cell are received simultaneously at intervals of a first duration. In addition, after sending the wake-up request, the terminal device may also directly start receiving synchronization signals and system messages, and start a timer with the first duration after sending the wake-up request. In this case, if the timer times out, a cell selection operation and / or a cell reselection operation is performed. In other words, a timer with the first duration may be used only to trigger a cell selection operation and / or a cell reselection operation, or may be used to trigger a cell selection operation and / or a cell reselection operation on the basis of being used to trigger the terminal device to receive synchronization signals and system messages.

[0380] In this embodiment, the target cell is awakened by sending a wake-up request by the terminal device to the serving cell. This can reduce the energy consumption of the target cell and, by triggering the terminal device, wake up the target cell in real time, thereby improving the flexibility of the target cell. In addition, after the target cell is awakened, the target cell sends the notification information to the serving cell, ensuring that the serving cell can promptly know the status of the target cell. This can then improve communication performance by using the target cell to share the traffic of the serving cell in the event of a communication failure.

[0381] Example 3:

[0382] In this embodiment, when the target cell is in an energy-saving state, the target cell is prohibited from performing uplink reception or is prohibited from receiving uplink reception other than a wake-up request for waking up the target cell, and is prohibited from sending downlink transmission other than a downlink discovery signal. In this case, the terminal device discovers the target cell through a downlink (DL) discovery signal and wakes up the target cell by sending a wake-up request to the target cell.

[0383] FIG9 is a schematic flowchart of a method 340 for waking up a target cell by sending a wake-up request to the target cell in the presence of a downlink discovery signal, provided in an embodiment of the present application.

[0384] As shown in FIG9 , assuming that the dormant cells that overlap with the coverage of the serving cell of the terminal device include dormant cell 1 and dormant cell 2, the method for waking up dormant cell 2 is described below by taking dormant cell 2 as the target cell. The method 340 may include:

[0385] S340: The target cell sends a downlink discovery signal.

[0386] Exemplarily, the downlink discovery signal may be SSB, CSI-RS or other downlink signals.

[0387] Exemplarily, the downlink reference signal may also be a reference signal specifically used to discover the target cell.

[0388] S341, the serving cell of the terminal device sends the configuration information of the target cell to the terminal device.

[0389] Exemplarily, the configuration information of the target cell includes at least one of the following:

[0390] Information used to indicate the frequency of the target cell;

[0391] Information used to indicate slices supported by the target cell;

[0392] System information of the target cell;

[0393] Configuration information of the wake-up request;

[0394] a timing offset between the serving cell and the target cell;

[0395] Configuration information used to identify whether the cell is close to the target cell.

[0396] It should be understood that the description of each information in the configuration information of the target cell can be found in the relevant description above, and to avoid repetition, it will not be repeated here.

[0397] S342, the terminal device sends a wake-up request to the target cell, where the wake-up request is used to request to wake up the target cell.

[0398] Exemplarily, the wake-up request wakes up the target cell via a ZC sequence or a preamble code request.

[0399] Exemplarily, a ZC sequence used in the wake-up request is different from a ZC sequence used in the target cell, or a root sequence used to generate the ZC sequence used in the wake-up request is different from a root sequence used in a neighboring cell of the target cell.

[0400] Exemplarily, when the terminal device is close to the target cell, the quality of the downlink discovery signal meets the wake-up requirement, and the target cell and the terminal device expect to wake up the target cell, the wake-up request is sent. Optionally, when the beam quality of the serving cell of the terminal device is greater than or equal to a first threshold value, and / or when the signal quality of the synchronization signal and / or physical broadcast channel block (Synchronization Signal / PBCH Block, SSB) of the serving cell is greater than or equal to a second threshold value, the terminal device determines that the terminal device is close to the target cell. When the frequency priority of the target cell is greater than the frequency priority of the serving cell of the terminal device, and / or when the slice supported by the target cell is the slice expected by the terminal device, the terminal device determines that the terminal device expects to wake up the target cell. Optionally, when the quality of the downlink discovery signal is greater than or equal to a third threshold value, the terminal device determines that the quality of the downlink discovery signal meets the wake-up requirement.

[0401] Exemplarily, the configuration information of the wake-up request in the configuration information of the target cell includes information for generating the wake-up request and / or information for configuring time-frequency resources for the wake-up request, and the information for generating the wake-up request includes at least one of the following: an identifier of the ZC sequence used by the wake-up request, an identifier of the preamble code used by the wake-up request, an identifier of the root sequence used to generate the ZC sequence or for generating the preamble code, and the time-frequency resources for the wake-up request are random access resources or time-frequency domain resources configured separately for the wake-up request.

[0402] Exemplarily, the configuration information of the target cell used to identify whether the cell is close to the target cell may include: the first threshold value, the second threshold value, and the third threshold value.

[0403] S343: After receiving the wake-up request from the terminal device, the target cell wakes up the target cell, that is, the target cell returns to a normal cell state or a non-energy-saving state.

[0404] Exemplarily, the target cell may directly wake up the target cell after receiving the wake-up request.

[0405] Exemplarily, after receiving the wake-up request, the target cell determines whether to wake up the target cell, and wakes up the target cell when it is determined to wake up the target cell.

[0406] Exemplarily, the target cell may determine whether to wake up the target cell based on at least one of the following:

[0407] The deployment location of the target cell, the time when the wake-up request is received, and the time period in which the wake-up request is received.

[0408] It's worth noting that in mobile communication networks, traffic distribution varies over time. For example, traffic may be less frequent at night and more frequent during the day, with even less traffic occurring around midnight. Furthermore, traffic distribution is also related to geographic location. For example, during the day, locations with many office buildings tend to have a high volume of users, but at night, there are almost no users. Urban or residential areas, on the other hand, experience low traffic during the daytime working hours, but may experience higher traffic at night. In light of this, in embodiments of the present application, whether to hibernate or awaken the target cell can be determined based on traffic volume. Furthermore, since the target cell is in an energy-saving state and does not know whether traffic is currently high or low, factors such as the target cell's deployment location, the time of receipt of the wake-up request, and the time period in which the wake-up request is received can reflect the serving cell's traffic volume. Therefore, by considering factors such as the target cell's deployment location, the time of receipt of the wake-up request, and the time period in which the wake-up request is received to determine whether to awaken the target cell, the network deployment of the target cell can dynamically adjust its state based on changes in traffic volume, for example, dynamically awakening or dormant the target cell or determining whether to awaken the target cell, thereby achieving network energy conservation.

[0409] S344, the target cell sends a synchronization signal and system message, etc. to the terminal device.

[0410] Exemplarily, the synchronization signal includes but is not limited to: a primary synchronization signal (PSS) and a secondary synchronization signal (SSS).

[0411] Exemplarily, the system message includes but is not limited to: System Information (SI), Master Information Block (MIB), System Information Block (SIB), and Remaining System Information (RMSI).

[0412] Exemplarily, after sending the wake-up request, the terminal device starts a timer with the first duration; if the timer times out, it receives the synchronization signal and system message sent by the target cell; and based on the synchronization signal and the system message, it performs a cell selection operation and / or a cell reselection operation.

[0413] Of course, in other alternative embodiments, if there is a paging message of the terminal device, the terminal device may further send the paging message to the terminal device after sending the wake-up request. For example, after sending the wake-up request, the paging message, the synchronization signal and the system message sent by the target cell are received simultaneously at intervals of a first duration. In addition, after sending the wake-up request, the terminal device may also directly start receiving synchronization signals and system messages, and start a timer with the first duration after sending the wake-up request. In this case, if the timer times out, a cell selection operation and / or a cell reselection operation is performed. In other words, a timer with the first duration may be used only to trigger a cell selection operation and / or a cell reselection operation, or may be used to trigger a cell selection operation and / or a cell reselection operation on the basis of being used to trigger the terminal device to receive synchronization signals and system messages.

[0414] S345: The target cell sends notification information to the serving cell indicating that the target cell has been awakened.

[0415] In this embodiment, the target cell is awakened by sending a wake-up request by the terminal device to the target cell. This can reduce the energy consumption of the target cell and wake up the target cell in real time by triggering the terminal device, thereby improving the flexibility of the target cell. In addition, after the target cell is awakened, the target cell sends the notification information to the serving cell, ensuring that the serving cell can promptly know the status of the target cell. In addition, the target cell can be used to share the traffic of the serving cell in the event of a communication failure, thereby improving communication performance.

[0416] Example 4:

[0417] In this embodiment, when the target cell is in an energy-saving state, the target cell is prohibited from performing uplink reception or is prohibited from receiving uplink reception other than a wake-up request for waking up the target cell, and is prohibited from sending downlink transmissions other than a downlink discovery signal. In this case, the terminal device wakes up the target cell by sending a wake-up request to the target cell through the serving cell of the terminal device.

[0419] As shown in FIG10 , it is assumed that the dormant cells that intersect with the coverage of the serving cell of the terminal device include dormant cell 1 and dormant cell 2. The following describes a method for waking up dormant cell 2 by taking dormant cell 2 as the target cell. The method 350 may include:

[0420] S350: The target cell sends a downlink discovery signal.

[0421] Exemplarily, the downlink discovery signal may be SSB, CSI-RS or other downlink signals.

[0422] Exemplarily, the downlink reference signal may also be a reference signal specifically used to discover the target cell.

[0429] a timing offset between the serving cell and the target cell;

[0430] Configuration information used to identify whether the cell is close to the target cell.

[0431] It should be understood that the description of each information in the configuration information of the target cell can be found in the relevant description above, and to avoid repetition, it will not be repeated here.

[0432] S352, the terminal device sends a wake-up request carrying the identification information of the target cell to the serving cell.

[0433] Exemplarily, the identification information includes the PCI of the target cell and the frequency of the target cell.

[0434] Exemplarily, the identification information includes a cell identification of the target cell.

[0435] Exemplarily, when the terminal device is close to the target cell, the quality of the downlink discovery signal meets the wake-up requirement, and the target cell and the terminal device expect to wake up the target cell, the wake-up request is sent. Optionally, when the beam quality of the serving cell of the terminal device is greater than or equal to a first threshold value, and / or when the signal quality of the synchronization signal and / or physical broadcast channel block (Synchronization Signal / PBCH Block, SSB) of the serving cell is greater than or equal to a second threshold value, the terminal device determines that the terminal device is close to the target cell. When the frequency priority of the target cell is greater than the frequency priority of the serving cell of the terminal device, and / or when the slice supported by the target cell is the slice expected by the terminal device, the terminal device determines that the terminal device expects to wake up the target cell. Optionally, when the quality of the downlink discovery signal is greater than or equal to a third threshold value, the terminal device determines that the quality of the downlink discovery signal meets the wake-up requirement.

[0436] Exemplarily, the configuration information of the wake-up request in the configuration information of the target cell includes information for configuring time-frequency resources for the wake-up request, and the time-frequency resources for the wake-up request are random access resources or time-frequency domain resources configured separately for the wake-up request.

[0437] Exemplarily, the configuration information of the target cell used to identify whether the cell is close to the target cell may include: the first threshold value, the second threshold value, and the third threshold value.

[0438] S353: After receiving the wake-up request from the terminal device, the serving cell forwards the wake-up request to the target cell.

[0439] Exemplarily, after receiving the wake-up request, the serving cell may directly forward the wake-up request to the target cell.

[0440] Exemplarily, after receiving the wake-up request, the serving cell determines whether to forward the wake-up request to the target cell, and forwards the wake-up request to the target cell when determining to forward the wake-up request.

[0441] Exemplarily, the serving cell may determine whether to forward the wake-up request to the target cell based on at least one of the following:

[0442] The traffic volume of the serving cell, the deployment location of the serving cell, the deployment location of the target cell, the time when the wake-up request is received, and the time period in which the wake-up request is received.

[0443] It is worth noting that in a mobile communication network, the distribution of services varies with time. For example, there will be less service at night and more service during the day, especially at midnight. At the same time, the distribution of services is also related to the geographical area. For example, during the day, there will be a large number of users in geographical locations with many office buildings, but there will be almost no users at night. In urban or residential areas, there will be very little service during the daytime working hours, but there may be more service at night.

[0444] S354: After receiving the wake-up request forwarded by the serving cell, the target cell wakes up the target cell, that is, the target cell returns to a normal cell state or a non-energy-saving state.

[0445] Exemplarily, the target cell may directly wake up the target cell after receiving the wake-up request.

[0446] S355a: The target cell sends notification information to the serving cell indicating that the target cell has been awakened.

[0447] S335b, the target cell sends a synchronization signal and system message, etc. to the terminal device.

[0448] Exemplarily, the synchronization signal includes but is not limited to: a primary synchronization signal (PSS) and a secondary synchronization signal (SSS).

[0449] Exemplarily, the system message includes but is not limited to: System Information (SI), Master Information Block (MIB), System Information Block (SIB), and Remaining System Information (RMSI).

[0474] FIG12 is a schematic block diagram of a terminal device 420 according to an embodiment of the present application.

[0475] As shown in FIG12 , the terminal device 420 may include:

[0476] The sending unit 421 is configured to send a wake-up request, where the wake-up request is used to request to wake up a target cell in an energy-saving state.
