For example, the UE can act as a scheduling entity, which provides sidelink signals between UEs in vehicle-to-everything (V2X) or device to device (D2D). For example, a cellular phone and a car communicate with each other using a sidelink signal. Cellular phones and smart home devices communicate without relaying communication signals through a base station. The network device in the embodiment of the present application may be a device for communicating with a terminal device, and the network device may also be referred to as an access network device or a wireless access network device, such as a base station. The network device in the embodiment of the present application may refer to a wireless access network (RAN) node (or device) that connects a terminal device to a wireless network. A base station may broadly cover various names as follows, or be replaced with the following names, such as: NodeB, evolved NodeB (eNB), next generation NodeB (gNB), relay station, access point, transmission point (TRP), transmission point (TP), master eNB (MeNB), secondary eNB (SeNB), multi-standard radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, base band unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station may be a macro base station, a micro base station, a relay node, a donor node, or the like, or a combination thereof. The base station may also refer to a communication module, modem or chip used to be set in the aforementioned equipment or device. The base station may also be a mobile switching center and a device that performs the base station function in D2D, V2X, machine-to-machine (M2M) communication, a network side device in a 6G network, and a device that performs the base station function in a future communication system. The base station may support networks with the same or different access technologies. The embodiments of the present application do not limit the specific technology and specific device form adopted by the network equipment. Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move based on the location of the mobile base station. In other examples, a helicopter or drone can be configured to act as a device that communicates with another base station. In some deployments, the network device in the embodiments of the present application may refer to a CU or a DU, or the network device includes a CU and a DU. The gNB may also include an AAU. The network equipment and terminal equipment can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on the water surface; they can also be deployed on aircraft, balloons and satellites in the air. The embodiments of the present application do not limit the scenarios in which the network equipment and terminal equipment are located. It should be understood that all or part of the functions of the communication device in the present application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (eg, a cloud platform). At present, as people pursue higher speed, latency, high-speed mobility, energy efficiency, and the diversity and complexity of services in future life, the 3GPP international standard organization has begun to develop 5G. The main application scenarios of 5G are: enhanced mobile broadband (eMBB), ultra reliability and low latency communication (URLLC), and massive machine type communications (mMTC). eMBB still aims at users to obtain multimedia content, services and data, and its demand is growing rapidly. On the other hand, since eMBB may be deployed in different scenarios, such as indoors, in urban areas, and in rural areas, its capabilities and requirements vary greatly, so it cannot be generalized and must be analyzed in detail in combination with specific deployment scenarios. Typical applications of URLLC include: industrial automation, power automation, remote medical operations (surgery), traffic safety, etc. Typical features of mMTC include: high connection density, small data volume, latency-insensitive services, low cost and long service life of modules, etc. Radio resource control (RRC) state and mobility management NR can also be deployed independently. In order to reduce air interface signaling and quickly restore wireless connections and data services in the 5G network environment, a new RRC state is defined, namely RRC inactive state (RRC_INACTIVE). This state is different from RRC idle state (RRC_IDLE) and RRC active state (RRC_ACTIVE). The following introduces these three states respectively. The RRC connection state may refer to the state of the terminal device after completing the random access process and before performing RRC release. An RRC connection exists between the terminal device and a network device (e.g., an access network device). In the RRC connection state, the terminal device may perform data transmission with the network device, such as downlink data transmission and / or uplink data transmission. Alternatively, the terminal device may also perform transmission of terminal device-specific data channels and / or control channels with the network device to transmit specific information or unicast information of the terminal device. In the RRC connected state, the network device can determine the cell-level location information of the terminal device, that is, the network device can determine the cell to which the terminal device belongs. In the RRC connected state, after the terminal device moves, such as from one cell to another, the network device can control the terminal device to perform cell handover. It can be seen that the mobility management of the terminal device in the RRC connected state may include cell handover. In addition, the mobility management of the terminal device in the RRC connected state can be controlled by the network device, and accordingly, the terminal device can switch to the specified cell according to the instructions issued by the network device. The RRC idle state refers to the state of the terminal device when the terminal device resides in the cell but does not perform random access. The terminal device usually enters the RRC idle state after being powered on or after RRC is released. In the RRC idle state, there is no RRC connection between the terminal device and the network device (such as the resident network device), the network device does not store the context of the terminal device, and no connection is established between the network device and the core network for the terminal device. If the terminal device needs to enter the RRC connected state from the RRC idle state, it is necessary to initiate the RRC connection establishment process. In the RRC idle state, the core network (CN) can send a paging message to the terminal device, that is, the paging process can be triggered by the CN. Optionally, the paging area can also be configured by the CN. In some cases, for a terminal device in the RRC idle state, when the terminal device moves (for example, from one cell to another), the terminal device can initiate a cell reselection process. In other cases, for a terminal device in the RRC idle state, when the terminal device needs to access a cell, the terminal device can initiate a cell selection process. That is, the mobility management of the terminal device in the RRC idle state may include cell reselection and / or cell selection. The RRC inactive state is a state defined to reduce air interface signaling, quickly restore wireless connections, and quickly restore data services. The RRC inactive state is a state between the connected state and the idle state. The terminal device has previously entered the RRC connected state and then released the RRC connection with the network device, but the network device saves the context of the terminal device. In addition, the connection established between the network device and the core network for the terminal device has not been released, that is, the user plane bearer and control plane bearer between the RAN and the CN are still maintained, that is, there is a CN-NR connection. In the RRC inactive state, the RAN can send a paging message to the terminal device, that is, the paging process can be triggered by the RAN. The RAN-based paging area is managed by the RAN, and the network device can know the location of the terminal device based on the RAN paging area level. In some cases, for a terminal device in an RRC inactive state, when the terminal device moves (for example, from one cell to another), the terminal device may initiate a cell reselection process. In other cases, for a terminal device in an RRC inactive state, when the terminal device needs to access a cell, the terminal device may initiate a cell selection process. That is, the mobility management of the terminal device in an RRC inactive state may include cell reselection and / or cell selection. Network Energy Saving Energy consumption has become an important part of operators' operating costs. According to a report by the Global System for Mobile Communications Association (GSMA), the energy cost of mobile networks accounts for about 23% of operators' total costs. Most of the energy consumption comes from radio access networks, especially active antenna units (AAUs), while data centers and optical fiber transmission account for only a small share. The power consumption mainly includes two parts: dynamic part, such as the consumption during data transmission / reception, and static part, such as the consumption to maintain the necessary operation of the wireless access device (even if there is no continuous data transmission / reception at this time). Research on network energy saving should not only evaluate the potential network energy consumption benefits, but also evaluate and balance the impact on network and user performance. For example, this research should not have a particularly large impact on some key performance indicators (KPIs), such as: spectrum efficiency, capacity, user perceived throughput, latency, power consumption of terminal equipment, complexity, handover performance, call drop rate, initial access performance, etc. In the RAN2#119 meeting, the following possible research directions for network energy saving were proposed. Solutions (solution groups): 1. Adaptation of MIB / SSB / SIB; -partial / simplified SSB; 2. Increase of SSB / SIB periodicity; 3. On demand SSB / SIB1 (FFS if there are enhancements for other SIBs) -FFS for on-demand MIB; 4. Receiving SSB / SIB on one carrier / cell and performing access to another carrier / cell; 5. Fast PCell change or switching for network edge services (handover / fast PCell change for NES); -Conditional switching or new configuration (CHO or new configuration); - Group handover (group HO); 6. Resource adaptation (frequency and time domain); - including PRACH, SRS, PUSCH, PUCCH resources and periodicities; -Cell discontinuous transmission / discontinuous reception (cell DTX / DRX); - measurement; -reference signal type and configuration of reference signal pattern for connected mode; -Partial bandwidth adaptation (BWP adaptation); 7. Any Cell activation / re-activation or UE wake up request signal (connected / idle); 8. Paging enhancements (includes paging-less solutions); 9. Cell selection / reselection (ie. cell prioritization also including legacy UEs) Things to study: 1. Study group configuration and signalling for transitions for different solutions; - pre-configuration and L1 / L2 signaling to trigger change of configuration; 2. Identify / capture RAN2 impact to legacy for the different solutions; 3. Awareness of the NES states at the UE side for the different solutions; 4. Aim to minimize DL signalling for NES; 5. Consider UE complexity and energy consumption; 6. UE assistance information for the specific network energy technique, it's benefits and impact to UE / NW. In order to achieve network energy saving, an energy-saving cell, or a cell with an energy-saving working state, such as an SSB-less cell, is proposed. For example, the energy-saving cell can achieve energy saving by reducing the transmission of common signals, or can achieve energy saving through discontinuous transmission (DTX) and / or discontinuous reception (DRX). The following is a brief introduction to SSB-less cells. SSB-less cells An SSB-less cell may refer to a cell that does not send part or all of the SSB, or may refer to a cell that does not send part or all of other public signals. In the related art, the secondary cell scell may be a cell that does not send SSB, and this cell and the special cell sPcell (including the primary cell and the primary and secondary cell) or other scells are cells in the system. As an SSB-less scell, the UE synchronizes with it, and according to the prior art, it is synchronized through the sPcell or other scells. The related contents of the absolute frequency SSB mentioned in the related art are as follows. The SSB frequency applies to the current serving cell. Unless otherwise specified, SSB-related parameters (such as SSB index) provided by the serving cell refer to this SSB frequency. The CD-SSB of a PCell is always on the synchronization raster. If the frequency can also be identified by the GSCN value, the frequency is considered to be on the synchronization raster (see TS 38.101-1

[0015] ). If this field is not present, the SSB related parameters are not present, such as SSB-positionsinburst, SSB-periodicityservingcell, and subcarrierSpacing in the ServingCellConfigCommon IE. If this field is not present, the UE obtains the timing reference from the SpCell or applicable cell (as described in TS 38.213

[0013] section 4.1). This operation is only supported when the Cell from which the UE obtains the timing reference is in the same frequency band as the Cell from which the terminal device obtains the timing reference (SpCell or Cell, respectively). (Frequency of the SSB to be used for this serving cell.SSB related parameters (eg SSB index) are provided for a serving cell refer to this SSB frequency unless mentioned otherwise.The CD-SSB of the PCell is always on the sync raster.Frequencies are considered to be on the sync raster if they are also identifiable with a GSCN value(see TS 38.101-1

[0015] ).If the field is absent,the SSB related parameters should be absent,egssb-PositionsInBurst,ssb-periodicityServingCell and subcarrierSpacing in ServingCellConfigCommon IE.If the field is absent,the UE obtains timing reference from the SpCell or an SCell if applicable as described in TS 38.213

[0013] , clause 4.1.This is only supported in case the Cell for which the UE obtains the timing reference is in the same frequency band as the cell (ie the SpCell or the SCell, respectively) from which the UE obtains the timing reference.) For cells supporting reduced capability (RedCap), this field corresponds to the CD-SSB. In R18, the network energy saving project is considering extending the intra-band approach to the inter-band scenario, that is, the SSB-less scell is an inter-band cell with the Pcell or other scell. In R19, SSB-less cells can be used as Scells or as independent cells. However, how SSB-less cells work as independent cells has not yet been proposed. It can be seen that the above energy-saving cells can save energy consumption, but how to realize the work in the energy-saving cells is an urgent problem to be solved. In order to solve the above problems, an embodiment of the present application provides a method for wireless communication, which receives information (i.e., first information) associated with a first cell (such as an SSB-less cell) through a terminal device, and based on the information, helps the terminal device to operate in the cell. Figure 2 is a flow chart of a method for wireless communication provided in an embodiment of the present application. The method shown in Figure 2 can be applied to communication between a terminal device and a first cell. The first cell may be a cell that does not send part or all of the common signals, such as the SSB-less cell mentioned above. Among them, the common signal may include one or more of a synchronization signal block SSB, a master information block MIB, a system information block SIB, a paging message, and system information content. The common signal mentioned here may include all system information content, or may include part of the system information content, such as MIB, and / or, SIB1, and / or, at least one of SIB2 / 3 / 4 / 5; or, at least one IE in the MIB / SIB1 / SIB2 / 3 / 4 / 5 information. The first cell may be a cell that can be discovered independently or can work independently. For example, the first cell can be discovered independently, which means that the first cell can be discovered or monitored by sending a first signal. For another example, the first cell can independently implement the communication process with the terminal device without the help of other cells. Among them, the first signal can be a discovery signal, an SSB signal, a simplified SSB signal, a non-SSB signal, etc. The first cell may also be a cell that cannot be discovered independently or cannot work independently. A cell that cannot be discovered independently, for example, can be discovered with the help of other cells (hereinafter, other cells associated with the first cell are referred to as second cells), or be indicated with the help of other cells, or realize communication with the terminal device. As an example, the terminal device can obtain information such as the time-frequency resource location and random access configuration of the first cell through other cells, so as to reside / select / reselect to the first cell based on the acquired information, or realize communication with the first cell. For another example, the terminal device can learn about the existence of the first cell through other cells, so as to obtain information about the first cell through the request information of the terminal device in other cells or the first cell, and then reside / select / reselect to the first cell, or realize communication with the first cell. For another example, a cell that cannot be discovered independently can send information such as a first signal (such as a discovery signal, etc.) at the request of other cells, so that the terminal device can reside / select / reselect to the first cell based on the discovery signal, or realize communication with the first cell. Referring to Fig. 2, the method 200 may include step S201. The method will be described below from the perspective of the interaction between the terminal device, the first cell and the second cell. In step S201, the terminal device receives the first information. Alternatively, the first cell sends the first information to the terminal device, and / or the second cell sends the first information to the terminal device. The first information may be associated with the first cell. The first information may be used for one or more of the following: indicating the first cell and / or the second information; identifying the first cell; synchronizing with the first cell; and providing information of the first cell. In some embodiments, the first information may be used to identify the first cell. For example, the terminal device may discover the first cell, identify the first cell, or measure the first cell through the first information. As an example, the first information may be the first signal described above. In some embodiments, the first information may be used to indicate the second information, wherein the second information includes information associated with the first cell. For example, the first information may include the second information, or the first information may indicate the location of the second information. In some other embodiments, the first information does not include the second information, or the second information is acquired after the first information is acquired. As an example, the second information is acquired through the first cell, and may also be acquired through other cells. As an example, the second information may include one or more of the following: time-frequency resources of the first cell; preamble of the first cell; random access channel (RACH) configuration information of the first cell; physical random access channel (PRACH) configuration information of the first cell; time-frequency resources for sending the first request information; paging configuration or time-frequency resources of the first cell; part or all of the public information of the first cell; and configuration information of the first request information. Among them, the first request information is a request message for the first cell. The first request information can be used to request to send or obtain one or more public signals of the first cell, and can also be used to request to execute a change in the working mode or working state of the first cell. The first request information will be introduced in detail later, and for the sake of brevity, it will not be repeated here. Based on the second information, it helps the terminal device to perform random access in the first cell and obtain relevant information of the first cell. In some embodiments, the first information may be used to synchronize with the first cell. For example, the first information may be a synchronization signal SSB of the first cell, or a simplified SSB signal. For another example, the first information may include a timing advance of the first cell. In some embodiments, the first information may be used to identify the first cell, or to learn the existence of the first cell. For example, the first information may be a discovery signal of the first cell, a synchronization signal SSB, a TRS, or a simplified SSB signal. In some embodiments, the first information may be used to know from which cell the information of the first cell is obtained. For example, the first information carries the association relationship between the first cell and other cells, or the first information tells from which frequency point / cell the information of the first cell is obtained. In some embodiments, the first information may be used to provide information of the first cell. For example, the first information may be used to provide a time-frequency resource location associated with the first cell. As an example, the time-frequency resource location may include the time-frequency resource location of the second information, or a request message may be sent to the first cell, such as the time-frequency resource location of the first request information, or the RACH / PRACH resource of the first cell. The time-frequency resource location of the request message may be used to request relevant information of the first cell and / or request the first cell to perform certain actions. In some embodiments, the first information may be obtained from the first cell or from the second cell, wherein the second cell is a cell associated with the first cell. For example, the second cell may be a primary cell of the terminal device, an anchor cell, a cell providing information of the first cell, a cell controlling or indicating the first cell, a cell receiving a request of the terminal device for the first cell, or a cell communicating with the terminal device before the terminal device accesses the first cell. Based on the first information associated with the first cell, the terminal device can identify the first cell, obtain information about the first cell, synchronize with the first cell, access the first cell, etc., thereby facilitating communication between the terminal device and the first cell. In some embodiments, based on the above-mentioned first information, the terminal device may perform one or more of the following: obtain the time-frequency resource location of the second information; send the first request information; identify the first cell; perform measurement; perform cell selection or reselection; reside; synchronize downlink with the first cell; perform a random access channel RACH process in the first cell; receive a paging message (paging) in the first cell; access the first cell; determine whether to reside in the first cell; determine whether to perform cell selection; determine whether to perform cell reselection; determine whether to perform cell switching; determine whether to perform cell redirection; determine whether to select the first cell; determine whether to reselect to the first cell; determine whether to switch to the first cell; determine whether to redirect to the first cell; and determine whether to use the first cell as a secondary cell; wherein the first request information is associated with the first cell. As described above, if the first information includes the second information, the terminal device can obtain the second information based on the first information. If the first information does not include the second information, the terminal device can obtain the time-frequency resource position of the second information based on the first information, and then obtain the second information based on the time-frequency resource position of the second information. If the first information does not include the second information, the terminal device can obtain the second information according to the predefined time-frequency resource information after learning the first information, or send the above-mentioned first request message. In some embodiments, the terminal device may send a first request message. For example, the terminal device may send a first request message to a first cell. As in the case where the first cell mentioned above is a cell that cannot be discovered / worked independently, or, as in the case where the first cell mentioned above is a cell that can be discovered / worked independently, the terminal device may send a first request message to the first cell. As another example, the terminal device may send a first request message to a second cell. As in the case where the first cell mentioned above is a cell that cannot be discovered / worked independently, or, as in the case where the first cell mentioned above is a cell that can be discovered / worked independently, the terminal device may send a first request message to the second cell. The above-mentioned first request information is associated with the first cell, such as the first request information can be used to request information associated with the first cell. For example, the first request information can be used to request to send or obtain one or more common signals of the first cell, and can also be used to request the first cell to perform certain actions, such as the conversion of the working mode or working state. For example, the first request information can be used to request other cells to control the behavior of the first cell, or to forward the request message so that the requesting device (such as UE) obtains one or more common signals of the first cell. In some cases, the terminal device may send a first request message to the first cell to request information associated with the first cell, and / or request the first cell to perform certain actions, such as a conversion of a working mode or working state. In other cases, the terminal device may send a first request message to the second cell to request information associated with the first cell. For example, the terminal device may receive information associated with the first cell from the second cell. For another example, the terminal device may receive information associated with the first cell from the first cell, before which the second cell may send a third request message to the first cell, and the third request message is associated with the first request message. If the first request message sent by the terminal device to the second cell is used to request the first cell to perform certain actions, the second cell may send a third request message to the first cell to request the first cell to perform certain actions. As an example, the third request message may be the same as the content of the first request message, or may include a part of the content of the first request message. Optionally, the third request message is implemented through interaction between base stations or through interaction of a core network. Optionally, the interface involved in the interaction may be N2 or Xn, etc. In some embodiments, the first request information is used to request sending or obtaining one or more public signals of the first cell, which may include multiple situations. For example, the first request information may be used to request sending or obtaining a specific one or several public signals of the first cell, or to request sending or obtaining one or more public signals that are not sent, broadcast or provided by the first cell. For another example, the first request information may be used to request sending or obtaining part or all of the system information / system information content of the first cell, or to request sending or obtaining part or all of the system information / system information content that are not sent, broadcast or provided by the first cell.

In some embodiments, the terminal device may perform cell selection or reselection based on the first information and / or other information (such as the second information, the information requested by the first request information, all or part of the common signal of the first cell, or information of other cells). For example, if the measurement result of the first information and the indication of the other information meet certain conditions, the terminal device selects or reselects to the first cell. In some embodiments, the terminal device may reside based on the first information. For example, the current serving cell of the terminal device is the first cell, and when the measurement result of the first information is greater than or equal to the first threshold, the terminal device may reside in the first cell. For another example, the current serving cell of the terminal device is not the first cell, and when the measurement result of the first information is less than or equal to the seventh threshold, the terminal device resides in the current serving cell. In some embodiments, the terminal device can reside based on the first information and / or other information (such as the second information, the information requested by the first request information, all or part of the common signal of the first cell, or information of other cells).

For example, based on the difference between the timing advance of the second cell and the timing advance of the first cell contained or indicated in the first information and / or other information, the terminal device may perform synchronization with the first cell based on the timing advance of the second cell and the difference between the timing advance of the second cell and the timing advance of the first cell. In some embodiments, the terminal device may perform a random access channel RACH procedure in the first cell based on the first information.

In some embodiments, the terminal device may receive a paging message in the first cell based on the first information and / or other information (such as the second information, the information requested by the first request information, all or part of the common signal of the first cell, or information of other cells). That is, the first cell may send a paging message (such as the first information and / or other information may include a paging message), and the terminal device may receive a paging message in the first cell. The area receives the paging message. In some embodiments, the terminal device may access the first cell based on the first information. In some embodiments, the terminal device can access the first cell based on the first information and / or other information (such as the second information, information requested by the first request information, all or part of the public signal of the first cell, or information of other cells).

In some embodiments, the terminal device can determine whether to reside in the first cell based on the first information and / or other information (such as the second information, the information requested by the first request information, all or part of the common signal of the first cell, or information of other cells); determine whether to perform cell selection; determine whether to perform cell reselection; determine whether to perform cell switching; determine whether to perform cell redirection; determine whether to select the first cell; determine whether to reselect to the first cell; determine whether to switch to the first cell; determine whether to redirect to the first cell; and determine whether to use the first cell as a secondary cell. If the first cell is the current serving cell of the terminal device, it can be determined whether to stay in the first cell based on the first information. If the first cell is the current service cell of the terminal device, it can be determined whether to stay in the first cell based on the first information and / or other information (such as the second information, the information requested by the first request information, all or part of the public signal of the first cell, or information of other cells). If the terminal device is in an idle state, it can determine whether to select the first cell or whether to reselect the first cell based on the first information. If the terminal device is in an idle state, it can determine whether to select the first cell or whether to reselect the first cell based on the first information and / or other information (such as the second information, information requested by the first request information, all or part of the public signal of the first cell, or information of other cells). If the current serving cell of the terminal device is not the first cell and the terminal device is in a connected state, the terminal device can determine whether to switch to the first cell, whether to redirect the first cell, or whether to use the first cell as a secondary cell based on the first information. If the current serving cell of the terminal device is not the first cell and the terminal device is in a connected state, the terminal device can determine whether to switch to the first cell, whether to redirect the first cell, or whether to use the first cell as a secondary cell based on the first information and / or other information (such as the second information, information requested by the first request information, all or part of the common signal of the first cell, or information of other cells). In some embodiments, the terminal device can determine whether to reside, select, reselect, switch, redirect or access the first cell; whether to receive paging in the first cell; whether to perform a RACH process in the first cell; or determine which cell / frequency point to reside, select, reselect, switch, redirect, receive paging, perform a RACH process or access (the above multiple behaviors can be referred to as the first behavior) based on one or more of the following information: whether the first information is detected; whether the second information is obtained; whether the time-frequency resource location of the second information is obtained; whether the first request information can be sent; the measurement result of the first information; the measurement result of the second cell; the comparison result of the measurement result of the first information and the measurement result of the second cell; the data to be transmitted; the R criterion; the S criterion; whether the terminal device supports carrier aggregation and / or dual connectivity CA / DC; the slice information of the terminal device; and the support of the first cell and / or the second cell for network slicing. In some embodiments, the terminal device may measure or detect the first information. The terminal device may determine whether to perform the first action based on whether the first information is detected. In some embodiments, the terminal device may determine whether to perform the first behavior based on whether the second information is obtained. If the terminal device obtains the second information, the first behavior may be performed; if the terminal device does not obtain the second information, the first behavior is not performed. For example, if the second information is obtained, the terminal device may perform a random access process, or paging, or send a first request message in the first cell. In some embodiments, the terminal device may determine whether to perform the first behavior based on whether the first information and the second information are obtained. If the terminal device obtains the first information and the second information, the first behavior may be performed; if the terminal device does not obtain at least one of the first information and the second information, the first behavior is not performed. For example, if the second information is obtained, the terminal device may perform a random access process, or paging, or send a first request message in the first cell. In some embodiments, the terminal device may determine whether to perform the first behavior based on whether the time-frequency resource location of the second information is obtained. For example, if the second information is not obtained, or if the second information is not included in the first information, the terminal device may determine whether to perform the first behavior based on whether the time-frequency resource location of the second information is obtained. In some embodiments, the terminal device may determine whether to execute the first behavior based on whether there is a predefined time-frequency resource location of the second information. For example, if there is no predefined time-frequency resource location, the terminal device determines whether to execute the first behavior. In some embodiments, when acquiring the first information, the terminal device acquires the second information. The first information and the second information mentioned here are independent, that is, the first information does not indicate or include the second information. In some embodiments, the terminal device may determine whether to execute the first action based on whether the first request information can be sent. If the first request information can be sent, the terminal device may execute the first action; if the first request information cannot be sent, the terminal device may not execute the first action. In some cases, the terminal device may determine whether one or more of the following information can be used based on the request result of the first request information: whether to reside in the first cell; whether to select the first cell; whether to reselect the first cell; whether to perform the RACH process in the first cell; whether to receive paging in the first cell; whether to switch to the first cell; whether to establish a connection or work in the first cell; and whether to redirect to the first cell. In some embodiments, the terminal device may determine whether to reside in the first cell, reselect to the first cell, or select to the first cell after acquiring at least one item in the SSB / SIB of the first cell. For example, at least one item in the SSB / SIB of the first cell may be acquired from the first cell, that is, the first cell sends at least one item in the SSB / SIB. For example, if at least one item in the SSB / SIB of the first cell allows the UE to access, reside, select / reselect the first cell, then the UE may reside in the first cell, reselect to the first cell, or select to the first cell. For example, if at least one item in the SSB / SIB of the first cell does not allow the UE to access, reside, select / reselect the first cell, then the UE may not reside in the first cell, reselect to the first cell, or select to the first cell within a certain period of time. If the first cell does not send SSB / SIB / paging, at least one item of SSB / SIB / paging can be obtained from the first cell and / or from the second cell through the above-mentioned first request information or other messages. As an example, the terminal device can directly request the first cell to send at least one item of SSB / SIB / paging, or request the first cell to send at least one item of SSB / SIB / paging through the second cell, such as the second cell instructs the first cell to send at least one item of SSB / SIB / paging through interfaces such as Xn / N2. As another example, the terminal device can request the second cell to send at least one item of SSB / SIB / paging of the first cell. In some embodiments, the terminal device may determine whether to perform the first action based on the measurement result of the first information. For example, if the measurement result of the first information is greater than or equal to the first threshold, the terminal device resides, selects or reselects to the first cell. Optionally, further based on or performing a final check, or based on part or all of the common signals (such as the first cell and / or other cells), determine whether to access, select, reselect, or reside in the first cell. The measurement result of the first information may include one or more of reference signal received power (RSRP), reference signal received quality (RSRQ), and received signal strength indication (RSSI). When the measurement result of the first information is compared with the threshold, the comparison can be made directly based on the measurement result of the first information, or the measurement result of the first information can be corrected before the comparison. For example, if the first threshold uses a threshold for a normal SSB signal, and the measurement result of the first signal is a measurement result of a simplified SSB or a discovery signal, then the measurement result of the first signal is corrected. For another example, if the measurement result of the first information satisfies the S criterion or the cell selection criterion, the terminal device selects the first cell. Optionally, further based on or performing a final check, or based on part or all of the public signals (such as the first cell and / or other cells), it is determined whether to select the first cell. For example, if the measurement result of the first information satisfies one or more of the following, the terminal device reselects to the first cell: R criterion; S criterion; and cell reselection criterion. Optionally, further based on or performing a final check, or based on part or all of the public signals (such as the first cell and / or other cells), it is determined whether to reselect to the first cell. In some embodiments, the terminal device may determine whether to perform the first behavior based on the measurement result of the second cell. For example, the terminal device may determine whether to perform the first behavior based on the measurement result of the first information and the measurement result of the second cell. The measurement result of the second cell may include the measurement result of one or more signals of a discovery signal, an SSB signal, a tracking reference signal, a simplified SSB signal, or a non-SSB signal. As an example, if the measurement result of the first information is greater than or equal to the third threshold and the measurement result of the second cell is less than or equal to the fourth threshold, the terminal device can reside in, select or reselect the first cell. Optionally, further based on or performing a final check, or based on part or all of the public signals (such as the first cell and / or other cells), determine whether to access, select, reselect, or reside in the first cell. As another example, the terminal device may determine whether to perform the first behavior based on a comparison result of the measurement result of the first information with a measurement result of the second cell. If the comparison result of the measurement result of the first information with the measurement result of the second cell is greater than or equal to the second threshold, the terminal device may reside, select, or reselect to the first cell. Optionally, further based on or performing a final check, or based on some or all of the common signals (such as those of the first cell and / or other cells), determine whether to access, select, reselect, or reside in the first cell. If the measurement result of the first information and the measurement result of the second cell are measurement results of the same signal, such as both are normal SSB signals, then the above comparison result can be determined based on the measurement result of the first information and the measurement result of the second cell, that is, the measurement result of the first information can be directly compared with the measurement result of the second cell to obtain the comparison result. If the measurement result of the first information and the measurement result of the second cell are measurement results of different signals, such as the measurement result of the first information is the measurement result of a simplified SSB signal, and the measurement result of the second cell is the measurement result of a normal SSB signal, then the above comparison result can be determined based on the correction result associated with the measurement result of the first information and the measurement result of the second cell, that is, before obtaining the above comparison result, the measurement result needs to be corrected. For example, the correction result associated with the measurement result of the first information can be a result obtained by correcting or varying (such as making certain changes) the measurement result of the first information. In some embodiments, the terminal device may determine whether to perform the first action based on the data to be transmitted. For example, if there is data to be transmitted, the terminal device resides, selects, or reselects to the first cell. For another example, if the terminal device has data to be transmitted and the amount of data to be transmitted is greater than or equal to the fourth threshold, the terminal device resides, selects, or reselects to the first cell. It can be determined based on the data information to be transmitted of the logical channel, or the service request information. In some embodiments, the terminal device may determine whether to perform the first behavior based on the slice information of the terminal device and the support of the network slice by the first cell and / or the second cell. For example, if the slice supported by the first cell is the same as the slice required by the terminal device, or the slice supported by the first cell includes the slice required by the terminal device, the terminal device resides in, selects, or reselects to the first cell. For another example, if the slice supported by the first cell is different from the slice required by the terminal device, or the slice supported by the first cell does not include, does not match, or does not support the slice required by the terminal device, the terminal device does not select or reselect to the first cell, or the terminal device selects or reselects to other cells. In some embodiments, the terminal device may determine whether to perform the first behavior based on whether the terminal device supports carrier aggregation (CA) and / or dual-connectivity (DC). For example, if the terminal device supports CA / DC, when the terminal device accesses the first cell, the first cell is the secondary cell of the terminal device. In some embodiments, if the measurement result of the current serving cell of the terminal device is less than or equal to a third threshold, such as when the signal quality of the current serving cell is poor, the terminal device resides in, selects or reselects to the first cell. In some embodiments, the terminal device may send a measurement report to the current serving cell, where the measurement report is used to indicate the channel quality of the first cell. For example, if the measurement result of the first information is greater than or equal to the first threshold, the terminal device sends a measurement report to the current serving cell. If the second cell is the current service cell of the terminal device, the terminal device receives the first indication information sent by the second cell, wherein the first indication information can be determined based on the above-mentioned measurement report, and the first indication information can be used to instruct the terminal device to switch or redirect to the first cell, or the terminal device transmits simultaneously with the first cell and the second cell. For example, if the terminal device has CA / DC capability, the first indication information is used to indicate that the first cell is used as a secondary cell of the terminal device, and the terminal device transmits simultaneously with the first cell and the second cell. As an example, the second cell can activate the first cell as a secondary cell of the terminal device by sending a secondary cell activation indication, such as a secondary cell activation medium access control control element (MAC CE). Alternatively, the second cell or the current label of the terminal device can add the first cell as a secondary cell of the terminal device. For another example, if the terminal device does not have CA / DC capability, the first indication information is used to instruct the terminal device to switch or redirect to the first cell. In some embodiments, if the network edge node cell can be used as a potential candidate cell, the terminal device can send the first request signal to determine whether it can access the cell. Optionally, the first request signal can be an uplink wake-up signal (WUS). In some embodiments, when one or more of the following conditions are met, the terminal device performs a random access process with the first cell: the first cell is a resident cell; the first cell is a cell selected by a cell; the first cell is a cell reselected by a cell; the channel quality of the first cell is greater than or equal to a fifth threshold; the terminal device has data to be transmitted; the amount of data to be transmitted is greater than or equal to a sixth threshold; the slices supported by the first cell are the same as the slices required by the terminal device; and the slices supported by the first cell include the slices required by the terminal device. For example, if the terminal device is in an idle state or an inactive state, and the first cell is a cell selected, the first cell is a cell reselected, or the channel quality of the first cell is greater than or equal to the fifth threshold, the terminal device performs a random access process with the first cell. For another example, if the terminal device is in a connected state (the current serving cell is the second cell), and the terminal device has data to be transmitted or the amount of data to be transmitted is greater than or equal to the sixth threshold, the terminal device can perform a random access process with the first cell. As an example, the terminal device can access the first cell as a secondary cell. In some embodiments, the terminal device performs a random access procedure with the first cell based on the RACH configuration information of the first cell, or synchronizes with the first cell. For example, when one or more of the above conditions are met, the terminal device performs a random access procedure with the first cell, or synchronizes with the first cell. When the terminal device sends the first request information or accesses the first cell, the terminal device can receive a physical downlink control channel (PDCCH) in the first cell and / or perform transmission with the first cell. However, under normal circumstances, there may be a certain delay in the first cell receiving the first request information or access information sent by the terminal device, and there may also be a certain delay in the first cell responding to the first request information or access information sent by the terminal device. Therefore, after the terminal device sends the first request information or accesses the first cell for the first duration, the terminal device can receive the PDCCH in the first cell and / or perform transmission with the first cell. The setting of the first duration helps to avoid invalid reception of the terminal device, thereby helping to save energy consumption. In some embodiments, the terminal device may receive the PDCCH in the first cell, and / or perform transmissions with the first cell. However, in some cases, such as the time limit of data transmission, the length limit of data, the length limit of resources, and the time limit of sending the common signal of the first cell, the terminal device cannot always work in the first cell. Therefore, within the second time period, the terminal device can receive the PDCCH in the first cell and / or perform transmission with the first cell. After the second time period, the terminal device may fall back to the second cell, or transmit with the second cell. The value of the second duration can be determined based on one or more of the above situations. For example, when the transmission resources of the first cell obtained by the terminal device from the second cell have no available transmission resources, or after the transmission is completed, it can fall back to the second cell. In this case, the value of the second duration can be determined based on the length of the transmission resources, or can be determined based on the transmission duration required for the data to be transmitted. The starting position or starting point of the second duration can be set according to demand or pre-configured. For example, the starting position or starting point of the second duration can be the position where the first duration ends. For another example, the starting point of the second duration can be the moment when the terminal device sends the first request, accesses the first cell, or successfully performs random access with the first cell. In some embodiments, the terminal device may perform transmission with the first cell and / or the second cell using time division multiplexing (TDM), or the terminal device may perform transmission with the first cell and the second cell alternately. In other embodiments, after the second time period, the terminal device may perform transmissions with the first cell and / or the second cell using TDM; or after the second time period, the terminal device may perform transmissions with the first cell and the second cell alternately. In some embodiments, after the terminal device falls back to the second cell, the terminal device may perform one or more of the following through the second cell: updating the information of the first cell; updating the system information of the first cell; updating the TA information of the first cell; receiving paging in the second cell; determining that the paging message is not supported by the first cell; obtaining update information of the transmission resource configuration between the first cell; and performing transmission with the second cell. The first cell may or may not send a paging message. If the first cell sends a paging message, the terminal device may obtain the paging message from the first cell. In some embodiments, the location of the paging message may meet one or more of the following requirements: association with the location of the first information; association with the location of the second information; a periodic location; and a valid location interval. For example, the location of the paging message can be configured to have a fixed interval, or a fixed relationship with the first information or the second information. For another example, the location of the paging message may appear periodically. For another example, the location of the paging message has a valid location interval and an invalid location interval, such as an on / off pattern, that is, the paging message exists only in the valid location interval. As an example, the paging message within the valid location interval may satisfy the requirement of having a fixed interval or a fixed relationship with the first information or the second information, or may appear periodically. As another example, the paging message within the valid location interval may not meet the above requirements. In some embodiments, the terminal device may monitor all paging message locations, that is, the time when the terminal device monitors the paging message is irrelevant to the identification of the terminal device. If the first cell does not send a paging message, the terminal device may obtain a paging message from the second cell. For example, the terminal device may receive a paging message of the second cell from the second cell, or receive a paging message of the first cell from the second cell. It should be noted that if the first cell receives a request message or the first cell state changes, such as changing to a normal working state, the first cell uses a conventional paging configuration or monitoring mechanism, that is, the paging configuration is a periodic configuration, and the monitoring location of the paging message is related to the identification of the terminal device. In some cases, the terminal device cannot directly obtain the first information and needs to send indication information to obtain the first information. For example, before the terminal device receives the first information, the terminal device can send the second indication information, and the second indication information can be used to instruct the first cell or the second cell to send the first information. For another example, after receiving the second indication information, the second cell can also send the third indication information to the first cell, and the third indication information can be used to instruct the first cell to send the first information. The resources for transmitting the second indication information or the third indication information may be predefined resources or resources of the second cell. In order to detect or measure the first signal, the terminal device needs to obtain the configuration or time-frequency resource location of the first signal. Therefore, as an implementation method, before the terminal device receives the first information, the terminal device can receive the third information sent by the second cell, and the third information can be used to indicate the configuration and / or time-frequency resource location of the first information. In some embodiments, the first information may be used to indicate a cell associated with the first cell, a cell synchronized with the first cell, or an anchor cell of the first cell. It should be noted that the method provided in the embodiment of the present application can be applied to a terminal device that is in at least one of an idle state, an inactive state or a connected state. The above describes how to work in an energy-saving cell (ie, the first cell) that does not send part or all of the common signals. The following describes how to work in an energy-saving cell configured with a cell-level DTX / DRX mechanism. Fig. 3 is a flow chart of a wireless communication method provided by another embodiment of the present application. The method 300 shown in Fig. 3 may include step S310. The method will be introduced from the perspective of the interaction between the terminal device and the network device. In step S310, the terminal receives the fourth information and / or the fifth information sent by the network device. Alternatively, the network device sends the fourth information and / or the fifth information to the terminal device. The network device is a network device corresponding to the third cell. The fourth information may be used to indicate DTX / DRX configuration information of the third cell. The configuration information may be applied to at least one of the terminal devices in the idle state, the inactive state and the connected state. In some embodiments, the above configuration information can be notified to the terminal device or the third cell through normal RRC signaling or system information. In some embodiments, the fourth information, ie, the DTX / DRX configuration information of the third cell, may be indicated in a dedicated RRC message. Optionally, the dedicated RRC message may be a group message or a UE-specific RRC message. In some embodiments, the fourth information may be updated through a system information update process or indication information carried by dedicated downlink control information (DCI) signaling. For example, a specific radio network temporary identifier (radio network The indication information carried by the DCI of the temporary identifier, RNTI) is updated. In some embodiments, the fourth information may also be used to indicate activation / deactivation of the DTX / DRX configuration information. For example, if the fourth information includes the DTX / DRX configuration information of the third cell, the fourth information represents or indicates activation of the DTX / DRX configuration information; if the fourth information does not include the DTX / DRX configuration information of the third cell, the fourth information represents or indicates deactivation of the DTX / DRX configuration information. For another example, the fourth information may carry a first identifier, and the first identifier may be used to indicate activation / deactivation of the DTX / DRX configuration information of the third cell. For another example, the fourth information may be used to indicate immediate activation or deactivation of the DTX / DRX configuration information of the third cell. In some cases, the fourth information may also indicate that the fifth information does not exist; or the fourth information may indicate that the fifth information is not used; or the fourth information may be used to indicate that the fifth information does not exist or is not needed. That is, the fourth information may indicate that separate activation / deactivation information is not used to indicate activation / deactivation of the DTX / DRX configuration information of the third cell. In some embodiments, the DTX / DRX configuration configured by the fourth information needs to be used in the case of activation / deactivation indication. For example, the DTX / DRX configuration configured by the fourth information determines whether to activate or deactivate based on the fifth information. In other embodiments, independent activation information, such as the fifth information, may be used to indicate activation / deactivation of the DTX / DRX configuration information of the third cell. For example, the fifth information may be used to indicate activation / deactivation of one of multiple sets of configuration information, or may be used to indicate activation / deactivation of one set of configuration information. For example, the fifth information may be used to indicate activation / deactivation of the DTX / DRX configuration (without indicating which set, for example, there is only one set of DTX / DRX configuration). The DTX / DRX configuration information of the third cell may be one or more sets of configuration information. The third cell may activate or use only one set of configuration information, or may activate or use multiple sets of configuration information at the same time. For example, different configuration information is used simultaneously or superimposed. As another example, the same configuration information is activated or used for different terminal devices. As another example, different configuration information is activated or used for different terminal devices. Optionally (but not limited to), the same or different terminal devices mentioned here can be determined based on network indications, or may refer to the different or same types of terminal devices, quality of service requirements, and RRC states. The fourth information, namely the DTX / DRX configuration information of the third cell, may optionally be the DTX / DRX configuration information of certain UEs of the third cell, or the DTX / DRX configuration information of the base station of the third cell. If a terminal device receives multiple indication messages for activating / deactivating DTX / DRX configurations, the terminal device may determine the indication message to be used according to one or more of the following information: the sending or receiving time of the multiple indication messages; the priority of the activation / deactivation indication message of the DTX / DRX configuration information; the priority of the DTX / DRX configuration information; the type of the activation / deactivation indication message of the DTX / DRX configuration information; the usage duration of the DTX / DRX configuration information; and the usage duration of the DTX / DRX configuration information used by the terminal device before receiving the multiple indication messages. In some embodiments, the indication information of multiple activation / deactivation DTX / DRX configurations received by the terminal device is carried in one or more of the following signaling: common RRC, SIB, system information, dedicated RRC, UE-specific RRC, dedicated MAC CE, common DCI, UE-specific DCI. In some embodiments, the terminal device may activate or deactivate DTX / DRX configuration information according to the latest indication information. In some embodiments, the terminal device may determine the DTX / DRX to be used or activated according to the priority of activating or deactivating the DTX / DRX signaling, or the priority of the DTX / DRX configuration information. The priority mentioned here may be, for example, a default priority (such as dedicated signaling is higher than common signaling, or UE-specific signaling is higher than common signaling, or UE-specific signaling is higher than other dedicated signaling), or it may be indicated by the network or predefined. For example, among the activation / deactivation indication information of the DTX / DRX configuration information carried in the RRC signaling specific to the terminal device, the dedicated RRC signaling, the dedicated DCI signaling, and the dedicated MAC CE, the terminal device considers that the activation / deactivation indication information of the DTX / DRX configuration information carried in the specific RRC signaling has the highest priority. If the activation / deactivation indication information of the DTX / DRX configuration information is carried in the RRC signaling specific to the terminal device, the dedicated RRC signaling, the dedicated DCI signaling, and the dedicated MAC CE, then the terminal device can activate / deactivate the DTX / DRX configuration information according to the indication information carried in the specific RRC signaling. For another example, if both the system information (or common RRC) and the dedicated RRC carry the DTX / DRX configuration information of the third cell, the terminal device prioritizes or uses the DTX / DRX configuration of the third cell carried by the dedicated RRC. It should be noted that the default priority order given above is only given as an example, and the default priority order may also be the opposite order, which is not limited in this application. In some embodiments, the terminal device may determine the DTX / DRX configuration to be used or activated according to the type of activation or deactivation DTX / DRX signaling, or the type of DTX / DRX configuration. For example, the terminal device may determine the DTX / DRX configuration to be used or activated using the indication information carried in the dedicated signaling (such as a dedicated RRC, UE-specific RRC, a dedicated MAC CE, a common DCI, or a UE-specific DCI). For another example, the UE determines the DTX / DRX configuration to be used or activated according to the indication of the UE-specific signaling (such as a UE-specific RRC, or a dedicated MAC CE, or a UE-specific DCI). In some embodiments, the terminal device may determine which DTX / DRX to use or activate according to the network's instructions on which DTX / DRX to use, or which activation or deactivation signaling to use. In some embodiments, before receiving multiple indication messages, the terminal device uses or sends the third duration of the DTX / DRX configuration information. Afterwards, the DTX / DRX configuration information is activated / deactivated according to the latest indication information, or the indication information may be updated. The latest indication information mentioned here may be received within the third time period, or may be received after the third time period. If the terminal device receives multiple indication information for activating / deactivating the DTX / DRX configuration, the terminal device can execute each of the multiple indication information, activate / deactivate the configuration information corresponding to each indication information, or maintain the activation / deactivation status of the DTX / DRX configuration; the terminal device can execute the latest indication information among the multiple indication information, activate / deactivate the configuration information corresponding to the latest indication information, or maintain the activation / deactivation status of the DTX / DRX configuration; the terminal device only executes the indication information in the terminal device-specific signaling, activates / deactivates the corresponding configuration information in the specific signaling, or maintains the activation / deactivation status of the DTX / DRX configuration; the terminal device only executes the indication information in the dedicated signaling, activates / deactivates the corresponding configuration information in the specific signaling, or maintains the activation / deactivation status of the DTX / DRX configuration; or the terminal device only executes the indication information in the signaling with the highest priority, activates / deactivates the corresponding configuration information in the specific signaling, or maintains the activation / deactivation status of the DTX / DRX configuration. If the terminal device receives multiple indication information for activating / deactivating the DTX / DRX configuration, and different indication information activates or deactivates different DTX / DRX configuration information, the terminal device can execute each of the multiple indication information, activate / deactivate the configuration information corresponding to each indication information, or maintain the activation / deactivation status of the DTX / DRX configuration; the terminal device can execute the latest indication information among the multiple indication information, activate / deactivate the configuration information corresponding to the latest indication information, or maintain the activation / deactivation status of the DTX / DRX configuration; the terminal device only executes the indication information in the terminal device-specific signaling, activates / deactivates the corresponding configuration information in the specific signaling, or maintains the activation / deactivation status of the DTX / DRX configuration; the terminal device only executes the indication information in the dedicated signaling, activates / deactivates the corresponding configuration information in the specific signaling, or maintains the activation / deactivation status of the DTX / DRX configuration; or the terminal device only executes the indication information in the signaling with the highest priority, activates / deactivates the corresponding configuration information in the specific signaling, or maintains the activation / deactivation status of the DTX / DRX configuration. If the terminal device receives multiple indication information for activating / deactivating the DTX / DRX configuration, and different indication information activates or deactivates the same DTX / DRX configuration information, the terminal device can execute each of the multiple indication information, activate / deactivate the configuration information corresponding to each indication information, or maintain the activation / deactivation status of the DTX / DRX configuration; the terminal device can execute the latest indication information among the multiple indication information, activate / deactivate the configuration information corresponding to the latest indication information, or maintain the activation / deactivation status of the DTX / DRX configuration; the terminal device only executes the indication information in the terminal device-specific signaling, activates / deactivates the corresponding configuration information in the specific signaling, or maintains the activation / deactivation status of the DTX / DRX configuration; the terminal device only executes the indication information in the dedicated signaling, activates / deactivates the corresponding configuration information in the specific signaling, or maintains the activation / deactivation status of the DTX / DRX configuration; or the terminal device only executes the indication information in the signaling with the highest priority, activates / deactivates the corresponding configuration information in the specific signaling, or maintains the activation / deactivation status of the DTX / DRX configuration. In some embodiments, if the terminal device activates part of the configuration information or maintains the activation / deactivation status of part of the configuration information according to part of the indication information in the multiple indication information, the terminal device can deactivate the configuration information corresponding to the remaining part of the indication information in the multiple indication information. In some embodiments, the dedicated information (i.e., the fifth information) carrying the activation / deactivation indication information of the DTX / DRX configuration may indicate the activation / deactivation of a DTX / DRX configuration, or indicate the activation / deactivation of a group or a set of DTX / DRX configurations, or indicate the activation / deactivation of multiple DTX / DRX configurations. In some embodiments, the dedicated information (i.e., the fifth information) carrying the activation / deactivation indication information of the DTX / DRX configuration may indicate the activation and deactivation of one or more DTX / DRX configurations. For example, indicating the activation of at least one DTX / DRX configuration, and indicating the deactivation of at least one DTX / DRX configuration. In some embodiments, the dedicated information (i.e., the fifth information) carrying the activation / deactivation indication information of the DTX / DRX configuration may only indicate the activation or deactivation of one or more DTX / DRX configurations. For example, only indicating the activation of at least one DTX / DRX configuration, or only indicating the deactivation of at least one DTX / DRX configuration. If the third cell is in the DTX / DRX sleep time period, the terminal device may perform one or more of the following operations: not receiving or transmitting common signals of the third cell, such as one or more of paging / SSB / SIB / RACH; not receiving or transmitting system information or system information changes associated with the third cell; not sending RACH information of the third cell; delaying sending and / or receiving information of the third cell; sending second request information to the third cell; determining that the third cell is a prohibited access cell; and not performing a random access procedure for the third cell. Alternatively, the network device may perform one or more of the following operations: not sending or transmitting common signals of the third cell, such as one or more of paging / SSB / SIB / RACH; not sending or transmitting system information or system information changes associated with the third cell; not receiving or responding to RACH information of the third cell; delaying sending and / or receiving information of the third cell; determining the third cell as a prohibited access cell; and not performing a random access procedure for the third cell. If the third cell is determined to be a prohibited access cell, the time during which the third cell is prohibited may be a predefined, preconfigured or specific duration (for example, 300 seconds), or a sleep time period of the third cell. If the sleep time period of the third cell is multiple or periodic time periods, the time during which the third cell is prohibited may be one or more time periods in the multiple time periods. The common signal of the third cell may include one or more of a synchronization signal block SSB, a master information block MIB, a system information block SIB, a paging message and system information or the contents thereof. In some embodiments, the second request information can be used to request the network device to instruct the third cell to perform one or more of the following operations: leave the DTX / DRX sleep state; deactivate / deconfigure the DTX / DRX configuration information; replace the DTX / DRX configuration information, i.e., use another set of DTX / DRX configuration information; and switch to a non-energy-saving mode or state. In some embodiments, the fourth information / or the fifth information is carried by one or more of the following: dedicated radio resource control RRC signaling; dedicated downlink control information DCI signaling; dedicated media access control information MAC CE; terminal device-specific RRC signaling; system message; and broadcast message. It should be noted that the fourth information and / or the fifth information are carried in the same or different types of signaling, such as RRC and RRC, RRC and DCI, RRC and MAC CE. In some embodiments, the method shown in FIG. 3 may further include step S320. In step S320, the terminal device sends the sixth information to the network device. Alternatively, the network device receives the sixth information sent by the terminal device. The sixth information may be feedback information for activation / deactivation indication information of the DTX / DRX configuration information. For example, the sixth information may be information for activation or deactivation of the DTX / DRB configuration, and the UE performs feedback. For another example, the sixth information may be information for dedicated signaling, such as common signaling, for activation or deactivation of the DTX / DRX configuration, and the UE performs feedback. For another example, the sixth information may be a signaling indication for activation or deactivation of the DTX / DRX configuration, and the UE performs feedback. In some embodiments, the sixth information may be used to indicate one or more of the following information: whether activation / deactivation indication information is received; and the activation / deactivation status of one or more sets of DTX / DRX configuration information. In some embodiments, the feedback information has a fixed size or length. In some embodiments, the feedback information may be variable in size or length. In some embodiments, the feedback information is carried by dedicated information, such as MAC CE, RRC, UCI. In some embodiments, the sixth information may carry information corresponding to all DTX / DRX configuration information. For example, UCI is of fixed size, and / or MAC CE is of fixed size, and / or, it may carry information corresponding to all DTX / DRX configurations. As an example, information of all DTX / DRX configurations is indicated by a bitmap (such as 1 for activation, 0 for deactivation, or 1 for deactivation, 0 for activation; for example, 1 for reception, 0 for non-reception, or 1 for non-reception, 0 for reception; for example, 1 for change, 0 for unchanged, or 1 for unchanged, 0 for change). For another example, UCI is of variable size, and / or MAC CE is of variable size, and / or, it may carry information corresponding to the received DTX / DRX configuration. Optionally, the feedback information carries information of the received configuration information (such as at least one of an identifier, a status, and a reception status). Taking the case where the UE uses MAC CE feedback and the configuration signaling is PDCCH as an example, the feedback method of the sixth information is introduced. For example, the MAC CE is of a fixed size, and / or the MAC CE carries information corresponding to all DTX / DRX configurations. As an example, a bitmap is used to indicate whether the activation / deactivation information corresponding to all DTX / DRX configurations is received (e.g., 1 represents received, 0 represents not received, or 0 represents received, 1 represents not received). For example, the index of the DTX / DRX indicated by the received activation / deactivation information is indicated by feedback. For another example, the MAC CE is of a fixed size, and / or the MAC CE carries information corresponding to all DTX / DRX configurations. As an example, a bitmap is used to indicate whether the PDCCH corresponding to all DTX / DRX configurations is received (e.g., 1 represents received, 0 represents not received, or 0 represents received, 1 represents not received). For example, the DTX / DRX index of the received PDCCH is indicated by feedback. For another example, the MAC CE is of a fixed size, and / or the MAC CE carries information corresponding to all DTX / DRX configurations. As an example, a bitmap is used to indicate whether all DTX / DRX configurations are activated or deactivated (e.g., 1 represents activation, 0 represents deactivation, or 0 represents activation, 1 represents deactivation). For example, the index of the DTX / DRX involved is indicated by feedback. For another example, optionally, the MAC CE is of variable size and / or carries information corresponding to the DTX / DRX configuration corresponding to the received PDCCH. Optionally, the feedback information carries an index of the DTX / DRX configuration corresponding to the PDCCH. For another example, the MAC CE is of a variable size and / or carries information corresponding to the DTX / DRX configuration corresponding to the received PDCCH. As an example, the feedback information carries an index of the DTX / DRX configuration corresponding to the PDCCH. For another example, the MAC CE is of variable size, and / or carries information corresponding to the DTX / DRX configuration of the activation / deactivation state change. As an example, the feedback information carries the index of one or more DTX / DRX configurations, or carries a bitmap indicating the DTX / DRX information of the activation / deactivation state change (such as 1 represents activation or state change, 0 represents deactivation or state unchanged, or 0 represents activation or state change, 1 represents deactivation or state unchanged). For another example, the MAC CE is of variable size, and / or carries information corresponding to the DTX / DRX configuration indicated by the activation / deactivation indication signaling. As an example, the feedback information carries one or more indexes of DTX / DRX configurations, or carries a bitmap indicating the DTX / DRX information indicated by the activation / deactivation indication signaling (such as 1, representing activation or signaling received, or 0, representing deactivation or signaling not received). For another example, the UE uses MAC CE to feedback the activation or deactivation status of DTX / DRX. As an example, the feedback information carries Information on the DTX / DRX configuration corresponding to the PDCCH (such as identification and / or status and / or PDCCH reception status). In some embodiments, the MAC CE is of a fixed size, and / or carries information corresponding to all DTX / DRX configurations. For example, indicating the status and / or identification of all DTX / DRX configurations. As an example, a bitmap is used to indicate whether all DTX / DRX configurations are activated or deactivated (such as 1 for activation, 0 for deactivation, or 0 for activation and 1 for deactivation). For example, the index of the activated or deactivated DTX / DRX is indicated by feedback, and / or the activation / deactivation status. In some embodiments, the MAC CE is of variable size and / or carries information corresponding to the DTX / DRX configuration corresponding to the received signaling. Optionally, the feedback information carries an index of the DTX / DRX configuration corresponding to the signaling and / or an activation / deactivation status of the corresponding DTX / DRX. In some embodiments, the feedback information includes a UE identifier. In some embodiments, the terminal device may receive fourth information repeatedly sent by the network device, the fourth information is repeatedly sent a number of times N, where N is an integer greater than or equal to 1; and / or, the terminal device may receive fifth information repeatedly sent by the network device, the fifth information is repeatedly sent a number of times M, where M is an integer greater than or equal to 1. M and / or N may be preconfigured or indicated by scheduling. In some embodiments, during the activation, deactivation and feedback process of the above-mentioned DTX / DRX configuration information, the DTX / DRX configuration of the cell can be identified by an index, that is, the indication information or feedback information can carry the index of the DTX / DRX configuration of the cell. In some embodiments, for a terminal device that has not received a dedicated PDCCH, has not received activation / deactivation signaling, has not activated a specific DTX / DRX configuration, has not deactivated a specific DTX / DRX configuration, has not activated DTX / DRX, or has not deactivated DTX / DRX, the network device may send dedicated signaling to re-execute activation or deactivation. It should be noted that the DTX / DRX configuration mentioned in the embodiments of the present application can be configured at the cell granularity. It should be noted that the third cell mentioned in the embodiment of the present application may be the first cell, the second cell or other cells mentioned above. It should be noted that the DTX / DRX mentioned above refers to DTX and / or DRX. It should be noted that each of the above-mentioned multiple embodiments can work independently or in combination with other embodiments. It should be noted that the “ / ” mentioned in the embodiments of the present application means “and / or”. Based on whether the first cell can be discovered / operated independently, the working mode of the terminal device in the first cell may be different. If the terminal device is in a different RRC state, the working mode of the terminal device in the first cell may also be different. The following takes the first cell as an SSB-less cell as an example, and combines embodiments 1 to 3 to introduce the working mode of the terminal device in the first cell for the terminal device in different RRC states and different types of first cells. Embodiment 1 Embodiment 1 may be applied to a scenario where the first cell can be discovered / operated independently and the terminal device is in an idle state or an inactive state. As an implementation method, the SSB-less cell sends a first signal, where the first signal is used by a terminal device to discover or measure the SSB-less cell, and / or determine other information (such as second information). As an implementation method, the terminal device requests information or requests configuration or requests state transition or accesses the SSB-less cell in the SSB-less cell according to the second information; or, the terminal device requests SSB-less to send information or send configuration or state transition from the anchor cell, and further, the anchor cell notifies the SSB-less cell to send information or send configuration or state transition (optionally, the SSB-less cell executes sending information or sending configuration or state transition); or, the terminal device accesses / requests resources or configuration of the SSB-less cell from the anchor cell. As an implementation manner, the SSB-less cell may send or not send SIB information. If the SIB information is not sent, the SIB may be obtained from the cell through a first request message or other messages, or the SIB of the SSB-less cell may be obtained through other cells. As an implementation manner, the terminal device resides in the SSB-less cell, or, after acquiring at least one SSB / SIB of the SSB-less cell, the terminal device resides in the SSB-less cell or determines whether to reside in the SSB-less cell. As an implementation method, the terminal device requests the SSB-less cell to send at least one item of SSB / SIB / paging in the SSB-less cell, or the terminal device requests the SSB-less cell to send at least one item of SSB / SIB / paging in the anchor cell (further, optionally, through interfaces such as Xn / N2, the anchor cell instructs the SSB-less cell to send at least one item of SSB / SIB / paging). If the terminal device obtains the SSB and / or MIB and / or SIB of the SSB-less cell (such as SIB1, further including at least one of SIB2 / 3 / 4 / 5), it determines whether it can reside in the SSB-less cell or reselect to the SSB-less cell or select the SSB-less cell according to the SSB and / or MIB and / or SIB of the SSB-less cell (for example, whether the SSB-less cell is barred, etc., for example, whether the slices supported by the SSB-less cell match / contain / equal to the slices required by the terminal device). As an implementation method, the terminal device determines whether to perform RACH in the SSB-less cell, or performs RACH in the SSB-less cell. For example, when the SSB-less cell is a cell for resident / cell selection / cell reselection, and / or the channel quality of the SSB-less cell is greater than or equal to a threshold, or the terminal device has data to be transmitted (such as according to the data information to be transmitted of the logical channel, or there is a service request), or the amount of data to be transmitted by the terminal device is greater than or equal to a threshold, or the slice supported by the SSB-less cell matches the slice required by the terminal device (such as being the same or containing), the terminal device initiates RACH or access in the SSB-less cell. As an implementation manner, for cell selection, the terminal device determines whether to perform selection for an SSB-less cell based on the first signal, or determines whether to select an SSB-less cell. Optionally, the first signal is a discovery signal, or a simplified SSB, or other signals. Optionally, based on the measurement result of the first signal, such as RSPR / RSRQ / RSSI, determine whether to perform cell selection or select the cell corresponding to the first signal. Optionally, based on the measurement result of the first signal and based on the measurement results with other cells, (and / or, whether the terminal device has data to be transmitted (such as according to the data to be transmitted information of LCH, or, there is a service request) or whether the data to be transmitted is greater than or equal to the threshold, and / or, the cell supports slices (for example, whether the slices supported by other cells / SSB-less cells match / include / equal to the slices required by the terminal device), determine whether to perform cell selection or select the corresponding SSB-less cell (or other cells). Optionally, other cells are based on the first signal or SSB measurement, or the measurement results of other cells are based on the first signal or SSB. Optionally, the measurement result based on the first signal itself or a variant thereof (such as making certain changes or corrections) is compared with the measurement result based on SSB. Optionally, the measurement result based on the first measurement satisfies the S criterion or the cell selection criterion before access to the SSB-less cell can be obtained. Optionally, if the terminal device detects that the first signal and / or the channel quality of the first signal is greater than or equal to a threshold, the terminal device determines whether to perform cell selection or whether to select the corresponding SSB-less cell. Optionally, the terminal device sends a first request message based on the first signal, or the terminal device detects that the first signal and / or the channel quality of the first signal is greater than or equal to a threshold, requesting the SSB-less cell to be converted to a non-energy-saving / normal state, or requesting at least one of SSB / SIB / paging of the SSB-less cell. Furthermore, the terminal device requests whether to select the SSB-less cell. (For example, the above is performed based on the first signal and the S criterion is met). For example, if a network edge node cell can be potentially a candidate to camp, then the terminal device can send an uplink wake-up signal to determine whether it can access the cell (if NES-cell can be potentially a candidate to camp, then UE sends UL-WUS, to check if it can be camped on.). As an implementation method, for cell reselection, the terminal device can determine whether to perform reselection for an SSB-less cell based on the first signal, or determine whether to reselect to an SSB-less cell. Optionally, the first signal is a discovery signal, or a simplified SSB, or other signals. Optionally, based on the measurement result of the first signal, such as RSPR / RSRQ / RSSI, determine whether to perform cell reselection or reselect the cell corresponding to the first signal. Optionally, based on the measurement result of the first signal and based on the measurement results with other cells, (and / or, whether the terminal device has data to be transmitted (such as according to the data to be transmitted information of LCH, or, there is a service request) or whether the data to be transmitted is greater than or equal to the threshold, and / or, the cell supports slices (for example, whether the slices supported by other cells / SSB-less cells match / include / equal to the slices required by the terminal device), determine whether to perform cell reselection or reselect the corresponding SSB-less cell (or other cells). Optionally, other cells are based on the first signal or SSB measurement, or the measurement results of other cells are based on the first signal or SSB. Optionally, the measurement result based on the first signal itself or a variant thereof (such as making certain changes or corrections) is compared with the measurement result based on SSB. Optionally, the measurement result based on the first measurement satisfies the R criterion and / or the S criterion or the cell reselection criterion before access to the SSB-less cell is possible. Optionally, if the terminal device detects that the first signal and / or the channel quality of the first signal is greater than or equal to a threshold, the terminal device determines whether to perform cell reselection or whether to reselect the corresponding SSB-less cell. Optionally, the terminal device sends a first request message to request the SSB-less cell to be converted to a non-energy-saving / normal state, or to request at least one of SSB / SIB / paging of the SSB-less cell, based on the first signal, or when the terminal device detects that the first signal and / or the channel quality of the first signal is greater than or equal to a threshold. Furthermore, the terminal device requests whether to reselect the SSB-less cell. (For example, the above is performed based on the first signal when the R and / or S criteria are met). For example, if a network edge node cell can be potentially a candidate to camp, then the terminal device can send an uplink wake-up signal to determine whether it can access the cell (if NES-cell can be potentially a candidate to camp, then UE sends UL-WUS, to check if it can be camped on.). As an implementation method, the terminal device requests information or requests configuration or access to the SSB-less cell in the SSB-less cell, receives PDCCH in the SSB-less cell, and / or performs transmission with the SSB-less cell. Further, the terminal device receives PDCCH in the SSB-less cell and / or performs transmission with the SSB-less cell when requesting SSB-less to send information or send configuration or state transition, or after the terminal device requests SSB-less to send information or send configuration or state transition, or after the first duration of requesting SSB-less to send information or send configuration or state transition. Optionally, the terminal device receives PDCCH in the SSB-less cell within a second duration, and / or performs transmission with the SSB-less cell. Optionally, the second duration may start at the end of the first duration. Optionally, the starting point of the second duration is when the terminal device sends a request or accesses the SSB-less cell or successfully transmits RACH with the SSB-less cell. Optionally, after the second time period, the terminal device falls back to the anchor cell to obtain SSB-less cell information or transmits in the anchor cell. Alternatively, as an implementation method, when the terminal device obtains information or configuration from the SSB-less cell or learns the state transition of the SSB-less cell, it receives the PDCCH in the SSB-less cell and / or performs transmission with the SSB-less cell. In the case of requesting SSB-less to send information or send configuration or state transition, or after, or after the first duration of requesting SSB-less to send information or send configuration or state transition, the terminal device receives PDCCH in the SSB-less cell, and / or performs transmission with the SSB-less cell. Optionally, the terminal device receives PDCCH in the SSB-less cell within a second duration, and / or performs transmission with the SSB-less cell. Optionally, the second duration may start at the end of the first duration. Optionally, the starting point of the second duration is that the terminal device sends a request or accesses the SSB-less cell or succeeds in RACH with the SSB-less cell. Optionally, after the second duration, the terminal device falls back to the anchor cell to obtain SSB-less cell information or transmits in the anchor cell. Alternatively, as an implementation method, when the terminal device accesses or requests the resources / configuration of the SSB-less cell from the anchor cell, the terminal device obtains the transmission resources (such as UL / DL) of the SSB-less cell from the anchor cell and transmits from the SSB-less cell. Optionally, within the second time period, or before the transmission of the transmission resources of the SSB-less cell obtained from the anchor cell or the transmission is completed, the terminal device receives PDCCH in the SSB-less cell and / or performs transmission with the SSB-less cell. Optionally, the starting point of the second time period is when the terminal device sends a request or accesses the SSB-less cell or the RACH with the SSB-less cell is successful. Optionally, after the second time period, when the terminal device obtains the transmission resources of the SSB-less cell from the anchor cell and there is no available transmission resources or after the transmission resources are completed, it falls back to the anchor cell to obtain new transmission resources of the SSB-less cell or transmits in the anchor cell. As an implementation method, the SSB-less cell does not send paging information. Correspondingly, the terminal device obtains paging information on other cells such as anchor cells. Optionally, the anchor cell is indicated by the first signal or the second information. As an implementation method, the SSB-less cell uses a specific configuration or position to send paging information. Optionally, the paging position is a position of the first signal with a fixed interval, or the paging position and the position of the second information have a fixed interval. Optionally, the paging position appears periodically, or the paging position has an on / off pattern. Optionally, the terminal device monitors at all paging positions, that is, the time when the terminal device monitors the paging is independent of the terminal device identification. A possible implementation of the first embodiment is as follows. As an implementation method, the SSB-less cell does not send part or all of the common signals, such as SSB and / or SIB information. The SSB-less cell sends a first signal. The first signal is used for the UE to discover or measure the SSB-less cell, and / or determine other information (such as second information). Optionally, the SSB-less cell sends a first signal after receiving the indication information. The indication information is sent by the anchor cell to the SSB-less cell to request the first signal to be sent, or the indication information is request information for the UE to request the SSB-less cell to send the first signal (for example, the anchor cell notifies the UE, such as notifying the UE of the location information of the SSB-less cell through the SIB, and the UE requests the SSB-less cell to send the first signal and / or the second information and / or send the first request signal according to the location information; for another example, when the location or channel quality of the UE and the anchor cell does not meet certain conditions, the UE requests the anchor cell to request the SSB-less cell to send the first signal or perform a state transition). For example, the first signal is used by an idle / inactive UE to measure or discover the SSB-less cell. For example, the first signal is a DL signal sent at a specific time-frequency resource position, and / or the first signal is a specific DL signal. For example, the first signal may carry the second information or indicate the location of the second information. Optionally, it includes at least one of the following: The second information is used by the UE to determine the time-frequency resources / preamble / RACH configuration / PRACH configuration on the SSB-less cell, and / or to determine the time-frequency resources / configuration information for sending the UL first request information. Optionally, correspondingly, the UE may use the second information to perform RACH or send UL first request information. Optionally, the UL first request message may be a request for the SSB-less cell to send part or all of the common signals, such as sending SSB and / or SIB information. Optionally, the UL first request message is used to request the SSB-less cell to perform a mode or state transition, or to request the SSB-less cell to send at least one or at least one of SSB / SIB / paging, such as from energy-saving mode to non-energy-saving mode, from SSB-less to normal state, or from not sending part or all of the common signals to sending part or all of the common signals. Optionally, the SSB-less cell does not send paging information. Correspondingly, the UE obtains paging information on other cells such as an anchor cell. Optionally, the anchor cell is indicated by the first signal or the second information. Optionally, the SSB-less cell uses a specific configuration or location to send paging information. Optionally, the location or configuration of the paging is such that there is a fixed interval, or a fixed relationship, between the first signal or the second information. Optionally, the paging location appears periodically, or the paging location has an on / off pattern. Optionally, the UE monitors at all paging locations, that is, the time when the UE monitors the paging is independent of the UE ID. As an implementation method, the UE measures or detects the first signal. Optionally, it includes one of the following: the UE measures or detects the first signal at a specific time-frequency resource location. The UE obtains the configuration and / or time-frequency resource location of the first signal of the SSB-less cell through the neighboring cell of the SSB-less cell. For example, the UE obtains the configuration and / or time-frequency resource location of the first signal of the SSB-less cell through dedicated RRC messages of other cells, such as RRCrelease, or system information, such as existing SIB or new SIB. Optionally, the other cell is an anchor cell. Optionally, according to the first signal, or, when the UE measures or detects the first signal, or, when the first signal satisfies the first condition (e.g., the channel quality / RSRQ / RSRP of the first signal is greater than or equal to threshold 1, or, the channel quality / RSRQ / RSRP of the first signal is greater than or equal to threshold 2, and the channel quality / RSRQ / RSRP of the cell where the current UE resides is less than or equal to the threshold 3), or, when the measurement result of the first signal meets the cell reselection or cell selection conditions (for example, according to the R / S criterion, the conditions for reselecting to the SSB-less cell are met), the UE reselects to the SSB-less cell, or sets the frequency or cell priority of the SSB-less cel to a high priority. Optionally, according to the first signal, or, if the UE detects the first signal, or according to the first signal, or, the first signal channel quality satisfies the R / S criterion (or the cell selection and / or reselection criterion), the UE sends the first request message. Optionally, the UE determines whether to reside in the corresponding SSB-less cell, or whether to reselect or select the corresponding SSB-less cell based on at least one item of SSB / SIB / paging of the requested SSB-less cell. Optionally, based on the first signal, or when the UE measures or detects the first signal, or when the first signal satisfies the second condition (e.g., the channel quality / RSRQ / RSRP of the first signal is less than or equal to threshold 1, or the channel quality / RSRQ / RSRP of the first signal is less than or equal to threshold 2, and the channel quality / RSRQ / RSRP of other cells is greater than or equal to threshold 3), or the measurement result of the first signal does not meet the conditions for reselection or selection or continuing to reside in the SSB-less cell (e.g., according to the R / S criterion, the conditions for reselection to other cells are met, or the conditions for residing in the SSB-less cell are not met), the UE reselects to other cells. Optionally, the UE gives priority to the anchor cell. Optionally, when the UE measures or detects the first signal, or when the first signal satisfies the first condition (such as, the channel quality / RSRQ / RSRP of the first signal is greater than or equal to threshold 1, or, the channel quality / RSRQ / RSRP of the first signal is greater than or equal to threshold 2, and the channel quality / RSRQ / RSRP of the cell where the current UE resides is less than or equal to threshold 3), or, when the amount of data to be transmitted by the UE satisfies the second condition (such as greater than or equal to the first threshold), or according to the first signal, or, the measurement result of the first signal does not meet the conditions for reselection or selection or continue to reside in the SSB-less cell (for example, according to the R / S criterion, the conditions for reselection to other cells are met, or, the conditions for reselection to the SSB-less cell are not met), or, in the MO case, or, when paging or MT is received, the UE performs the first behavior. Optionally, the first behavior may include at least one of the following: obtaining time-frequency resources / configuration of the second information, executing RACH, determining whether to stay, executing cell selection or reselection, and sending one or more of UL first request information; the UE measures or detects the first signal; the UE measures or detects the first signal when the channel quality of the cell (such as other cells or anchor cells) in which the UE stays is less than or equal to the second threshold; the UE obtains the second information according to the first signal; or, obtains the time-frequency resources / configuration carrying the second information, and obtains the second information; the UE sends the first request information at a specific time-frequency resource position; if the UE does not obtain the second information, or does not obtain the time-frequency resources / configuration carrying the second information, the UE executes RACH or sends the first request information through the anchor cell; the UE sends the UL first request information through the SSB-less cell; the UE obtains the second information, or obtains the time-frequency resources / configuration carrying the second information, and the UE sends the UL first request information through the SSB-less cell; the UE obtains the time-frequency resources / configuration carrying the second information of the second information, and the second information is information for RACH / PRACH, then the UE executes RACH through the SSB-less cell. Otherwise, the UE performs RACH or sends the first request information through the anchor cell. As an implementation method, the network device may perform the second behavior, and / or the UE may perform the third behavior. The network device may be a base station of an SSB-less cell, and / or a gNB of an anchor cell.

Optionally, the second behavior includes at least one of the following: receiving RACH information (or, performing a RACH process. For example, if the Rach configuration of the SSB-less cell is sent through the anchor cell, or, is carried in the second information), receiving first request information, sending the RACH configuration of the SSB-less cell (if the Rach configuration of the SSB-less cell is not sent through the anchor cell, or, is not carried in the second information), sending at least one item of SSB / SIB / paging, performing a cell or network state transition, sending PDCCH / PDSCH in the SSB-less cell, receiving PUSCH in the SSB-less cell, and performing transmission with the UE. Optionally, the behavior is a behavior related to the base station or cell of the SSB-less cell.

Optionally, the second behavior includes paging. Optionally, the SSB-less cell does not send paging information. Correspondingly, the UE obtains paining information on other cells such as an anchor cell. For example, the anchor cell is indicated by the first signal or the second information. Optionally, the SSB-less cell sends paging information using a specific configuration or position. As an example, the position or configuration of the paging is such that there is a fixed interval, or a fixed relationship, between the first signal or the second information. As another example, the paining position appears periodically, or the paging position has an on / off pattern. Optionally, the UE listens at all paging positions, that is, the time when the UE listens to the paging is independent of the UE ID. Optionally, upon receiving a request message or in the case of SSB-less state transition, the existing paging configuration or monitoring mechanism is used in the SSB-less cell, that is, the paging configuration is periodic configuration, and the paging detection position of the UE is related to the UE ID. Optionally, if the SSB-less cell falls back to not sending all or part of the public information, the UE performs paging according to the SSB-less cell not sending paging information or the SSB-less cell sending paging information using a specific configuration or location. Optionally, if the SSB-less cell sends all or part of the public information, the UE performs paging according to the SSB-less cell not sending paging information or the SSB-less cell sending paging information using a specific configuration or location; or if the SSB-less cell falls back to not sending all or part of the public information, the UE performs paging according to the SSB-less cell not sending paging information or the SSB-less cell sending paging information using a specific configuration or location. Optionally, the third behavior includes at least one of the following: sending a first request message, executing RACH according to the RACH configuration of the SSB-less cell, requesting the SSB-less cell to send at least one of SSB / SIB / paging, requesting the SSB-less cell to perform a cell or network state transition, requesting the SSB-less cell to send a configuration or information, requesting or obtaining the configuration or transmission resources of the SSB-less cell (for example, through a dedicated RRC configuration, such as RRC reconfiguration / RRCrelease, or SIB information), determining whether to reside in the SSB-less cell, whether to perform cell selection / reselection, whether to select / reselect the SSB-less cell, requesting or obtaining SSB-less cell configuration or public through an anchor cell, accessing and requesting or obtaining the configuration or transmission resources of the SSB-less cell through an anchor cell, and performing transmission with the SSB-less cell. Optionally, the UE resides in the SSB-less cell, or the UE resides in the SSB-less cell after acquiring at least one SSB / SIB of the SSB-less cell. Optionally, the UE requests the SSB-less cell to send at least one item of SSB / SIB / paging in the SSB-less cell, or the UE requests the SSB-less cell to send at least one item of SSB / SIB / paging in the anchor cell (further, optionally, through interfaces such as Xn / N2, the anchor cell instructs the SSB-less cell to send at least one item of SSB / SIB / paging). If the UE obtains the SSB and / or MIB and / or SIB of the SSB-less cell (such as SIB1, further including at least one of SIB2 / 3 / 4 / 5), it determines, according to the SSB and / or MIB and / or SIB of the SSB-less cell, whether it can reside in the SSB-less cell or reselect to the SSB-less cell or select the SSB-less cell (for example, whether the SSB-less cell is barred, etc., for example, whether the slices supported by the SSB-less cell match / include / equal to the slices required by the UE). Optionally, the UE determines whether to perform RACH in the SSB-less cell, or performs RACH in the SSB-less cell. For example, when the SSB-less cell is a cell for resident / cell selection / cell reselection, and / or the channel quality of the SSB-less cell is greater than or equal to a threshold, or the UE has data to be transmitted (such as according to the information of data to be transmitted on the LCH, or there is a service request), or the amount of data to be transmitted by the UE is greater than or equal to a threshold, or the slice supported by the SSB-less cell matches the slice required by the UE (such as being the same or containing), the UE initiates RACH or access in the SSB-less cell. For example: the UE requests information or requests configuration or access to the SSB-less cell in the SSB-less cell, receives PDCCH in the SSB-less cell, and / or performs transmission with the SSB-less cell. Further, the UE receives PDCCH in the SSB-less cell and / or performs transmission with the SSB-less cell in the case of requesting SSB-less to send information or send configuration or state transition, or after, or after the first duration of requesting SSB-less to send information or send configuration or state transition. Optionally, the UE receives PDCCH in the SSB-less cell within a second duration, and / or performs transmission with the SSB-less cell. For example: When the UE obtains information from an SSB-less cell or obtains configuration or learns of a state transition of an SSB-less cell, the UE receives PDCCH in the SSB-less cell and / or performs transmission with the SSB-less cell. Furthermore, when the UE requests SSB-less to send information or send configuration or state transition, or after, or after the first duration of requesting SSB-less to send information or send configuration or state transition, the UE receives PDCCH in the SSB-less cell and / or performs transmission with the SSB-less cell. Optionally, the UE receives PDCCH in the SSB-less cell within a second duration and / or performs transmission with the SSB-less cell. For example: when the UE accesses or requests resources / configuration of an SSB-less cell from an anchor cell, the UE obtains transmission resources (such as UL / DL) of the SSB-less cell from the anchor cell and transmits from the SSB-less cell. Optionally, the UE receives PDCCH in the SSB-less cell within the second time period, or before the transmission of the transmission resources of the SSB-less cell obtained from the anchor cell or the transmission is completed, and / or performs transmission with the SSB-less cell. Optionally, when the UE has no available transmission resources when obtaining transmission resources of the SSB-less cell from the anchor cell or after the transmission resources are completed, the UE falls back to the anchor cell to obtain new transmission resources of the SSB-less cell or transmits in the anchor cell. For example, the first duration may be a first timer. For example, when the UE requests an SSB, the terminal device starts a first timer, and when the first timer expires, the UE starts transmitting with the SSB-less cell. As an implementation, the UE keeps working on the SSB-less cell without falling back to the anchor cell. For example, the second duration may be a second timer, or an available time period on the time pattern, or one or more periodic time periods. For example, for the second timer, the UE transmits with the SSB-less cell only during the running time of the second timer. If the second timer is not running, the UE may stop transmitting with the SSB-less cell or fall back to the anchor cell. The method provided in the embodiment of the present application enables a non-connected UE to communicate with an SSB-less cell without the SSB-less cell sending part or all of the common signals. Embodiment 2 Embodiment 2 can be applied to a scenario where the terminal device is in a connected state. In this case, the first cell can be independently discoverable / operable. A cell may also be a cell that cannot be discovered / worked independently. As an implementation manner, the UE is in a connected state. For example, the connected state UE currently resides in and is connected to other cells, such as anchor cells, other non-anchor / non-SSB-less cells. As an implementation manner, the UE measures or detects a signal of an SSB-less cell. As an implementation method, if the UE measures or detects the signal of the SSB-less cell, or the measurement or detection of the signal of the SSB-less cell meets certain conditions, or the measurement results of the UE and the anchor cell meet certain conditions, the UE reports the measurement results to the anchor cell, or the UE has data to be transmitted (such as according to the data to be transmitted information of the LCH, or there is a service request) or the data to be transmitted by the UE is greater than or equal to the threshold, or the slice supported by the SSB-less cell matches / includes / equals the slice required by the UE, or the UE receives an indication from the anchor cell or the currently connected cell, or the UE requests the anchor cell to send part or all of the public information (such as at least one of SSB, SIB, paining) and / or requests an SSB-less cell state transition. Alternatively, the UE uses the measurement report to indicate the channel quality of the SSB-less cell to the current cell (and, optionally, the current cell can indicate or trigger the SSB-less cell state transition, or instruct the SSB-less cell to send at least one of SSB / SIB / paing), or the UE sends a first request signal to the SSB-less cell (optionally, refer to Embodiment 1), or the UE performs RACH or performs UL synchronization in the SSB-less cell. Optionally, after the anchor cell or the current cell of the UE learns the report or indication of the UE, if the UE is a CA-capable UE, the anchor cell or the current cell of the UE may send a Scell ​​activation indication, such as a Scell ​​activation MAC CE, to activate the SSB-less cell as the Scell ​​of the UE. Alternatively, the anchor cell or the current tag of the UE may add the SSB-less cell as the Scell ​​of the UE. Optionally, if the UE is a non-CA-capable UE, the anchor cell or the UE's current cell may switch the UE to the SSB-less cell. As an implementation method, the SSB-less cell may or may not send SIB information. If the SIB information is not sent, the UE may obtain the SIB through the dedicated RRC of the SSb-less cell. Alternatively, the SIB may be obtained from the cell through a first request message or other messages, or the SIB of the SSB-less cell may be obtained through other cells. As an implementation method, the UE obtains the RACH configuration of the SSB-less cell from the anchor cell or the UE's current cell or the SSB-less cell, and performs UL synchronization with the SSB-less cell. Alternatively, the UE obtains the UL TA time difference between the SSB-less cell and the anchor cell from the anchor cell or the UE's current cell, and performs UL synchronization with the SSB-less cell according to the TA between the UE and the anchor cell or the UE's current cell and the time difference.

Further, optionally, if the UE switches or redirects to an SSB-less cell, the UE obtains system information from the SSB-less cell, and / or paging. Further, optionally, the UE switches to or rediects to the SSB-less cell, and the UE works in the SSB-less cell and the cell / anchor cell before the switching in a TDM manner, for example, periodically or TDM-acquires paging or updated system information from the cell / anchor cell before the switching. Further, optionally, after switching to the SSB-less cell, the UE obtains system information of the SSB-less cell through a dedicated RRC. Optionally, when the fourth condition is met, the connected UE transmits with the anchor cell / UE's current cell and the SSB-less cell simultaneously, that is, the SSB-less cell serves as a secondary cell.

Optionally, the UE obtains the SSB-less cell information indicated by the anchor cell, such as the RACH configuration information, or the measurement configuration information, through the SIB of the anchor cell (such as a dedicated SSB, or an existing SIB), or the RRC reconfiguration message. When the UE finds an SSB-less cell and the channel quality of the SSB-less cell is greater than or equal to threshold 1, the UE performs RACH from the SSB-less cell. Perform UL synchronization with the SSB-less cell. Then, receive PDCCH from the SSB-less cell and / or perform transmission.

Optionally, the UE obtains information about the SSB-less cell based on information carried by other cells, or the existence of the SSB-less cell, or information about the SSB-less cell (such as system information, such as RACH configuration). For example, the SIB of the anchor cell or a dedicated RRC message (such as RRC reconfiguration or RRC release) carries information about the SSB-less cell, such as system information, such as RACH configuration. Alternatively, the UE obtains a first signal sent by the SSB-less cell, where the first signal is used by the UE to discover or measure the SSB-less cell, and / or to determine other information (such as third information. Optionally, the third information is information of a cell associated with the SSB-less cell, or information of a cell synchronized with the SSB-less cell, or an anchor cell of the SSB-less cell. Optionally, the third information is used by the UE to access the network from a corresponding cell (such as a cell associated / synchronized with the SSB-less cell or an anchor cell, and / or to obtain information of the SSB-less cell, such as SIB / RACH). As an implementation method, the UE sends a first request message in the anchor cell to request the SSB-less cell to send part or all of the public information (such as SIB), or to perform a state transition, or to request at least one of SSB / SIB / paging of the SSB-less cell. Alternatively, the UE requests configuration information of the SSB-less cell, such as RACH configuration. As an implementation method, the SSB-less cell may or may not send all or part of the common signal. If the all or part of the common signal is not sent, the all or part of the common signal may be obtained from the cell through a first request message or other message, or the all or part of the common signal of the SSB-less cell may be obtained through other cells. Optionally, the all or part of the common signal may be the all or part of the common signal described in Example 1. Optionally, the SSB-less cell may send or not send MIB information. If the MIB information is not sent, the MIB may be obtained from the cell through a first request message or other messages, or the MIB of the SSB-less cell may be obtained through other cells. As an implementation manner, the SSB-less cell may send or not send SIB information. If the SIB information is not sent, the SIB may be obtained from the cell through a first request message or other messages, or the SIB of the SSB-less cell may be obtained through other cells. As an implementation method, the UE synchronizes with the SSB-less cell through the RACH configuration of the SSB-less cell. Alternatively, the UE accesses the network from the anchor cell (optionally, the RACH configuration of the anchor cell is used to synchronize with the anchor cell. Optionally, the RACH configuration may be a dedicated configuration for the anchor cell to learn that the UE needs to transmit with the SSB-less cell). As an implementation manner, an idle or inactive UE may access the network from an SSB-less cell. Optionally, the UE resides in the SSB-less cell, or, after acquiring at least one SSB / SIB of the SSB-less cell, the UE resides in the SSB-less cell or determines whether to reside in the SSB-less cell. Optionally, the UE requests the SSB-less cell to send at least one item of SSB / SIB / paging in the SSB-less cell, or the UE requests the SSB-less cell to send at least one item of SSB / SIB / paging in the anchor cell (further, optionally, through interfaces such as Xn / N2, the anchor cell instructs the SSB-less cell to send at least one item of SSB / SIB / paging). If the UE obtains the SSB and / or MIB and / or SIB of the SSB-less cell (such as SIB1, further including at least one of SIB2 / 3 / 4 / 5), it determines, according to the SSB and / or MIB and / or SIB of the SSB-less cell, whether it can reside in the SSB-less cell or reselect to the SSB-less cell or select the SSB-less cell (for example, whether the SSB-less cell is barred, etc., for example, whether the slices supported by the SSB-less cell match / include / equal to the slices required by the UE). Optionally, the UE determines whether to perform RACH in the SSB-less cell, or performs RACH in the SSB-less cell. For example, when the SSB-less cell is a cell for resident / cell selection / cell reselection, and / or the channel quality of the SSB-less cell is greater than or equal to a threshold, or the UE has data to be transmitted (such as according to the information of data to be transmitted on the LCH, or there is a service request), or the amount of data to be transmitted by the UE is greater than or equal to a threshold, or the slice supported by the SSB-less cell matches the slice required by the UE (such as being the same or containing), the UE initiates RACH or access in the SSB-less cell. Optionally, for cell selection, the UE determines whether to perform selection for an SSB-less cell based on the first signal, or determines whether to select an SSB-less cell. For example, the first signal is a discovery signal, or a simplified SSB, or other signals. For example, based on the measurement result of the first signal, such as RSPR / RSRQ / RSSI, etc., determine whether to perform cell selection or select the cell corresponding to the first signal. For example, based on the measurement result of the first signal and based on the measurement results of other cells, (and / or, whether the UE has data to be transmitted (such as according to the data to be transmitted information of the LCH, or, there is a service request) or whether the data to be transmitted is greater than or equal to the threshold, and / or, the cell supports slices (for example, whether the slices supported by other cells / SSB-less cells match / include / equal to the slices required by the UE), determine whether to perform cell selection or select the corresponding SSB-less cell (or other cells). Optionally, other cells are based on the first signal or SSB measurement, or the measurement results of other cells are based on the first signal or SSB. Optionally, based on the measurement result of the first signal itself or The variation thereof (such as making certain changes or corrections) is compared with the measurement result based on SSB. Optionally, the SSB-less cell can be accessed only if the measurement result based on the first measurement satisfies the S criterion or the cell selection criterion. For example, if the UE detects that the first signal and / or the channel quality of the first signal is greater than or equal to a threshold, the UE determines whether to perform cell selection or whether to select the corresponding SSB-less cell. For example, the UE sends a first request message based on the first signal, or the UE detects that the first signal and / or the channel quality of the first signal is greater than or equal to the threshold, requesting the SSB-less cell to be converted to a non-energy-saving / normal state, or requesting at least one of the SSB / SIB / paging of the SSB-less cell. Then, the UE requests whether to select the SSB-less cell. (For example, the above is performed based on the first signal when the S criterion is met). For example, if a network edge node cell can be potentially a candidate to camp, then the terminal device can send an uplink wake-up signal to determine whether it can access the cell (if NES-cell can be potentially a candidate to camp, then UE sends UL-WUS, to check if it can be camped on.). For example, for cell reselection, the UE determines whether to perform reselection for an SSB-less cell based on the first signal, or determines whether to reselect to an SSB-less cell. For example, the first signal is a discovery signal, or a simplified SSB, or other signals. For example, based on the measurement result of the first signal, such as RSPR / RSRQ / RSSI, determine whether to perform cell reselection or reselect the cell corresponding to the first signal. For example, based on the measurement result of the first signal and based on the measurement results of other cells, (and / or, whether the UE has data to be transmitted (such as according to the data to be transmitted information of the LCH, or, there is a service request) or whether the data to be transmitted is greater than or equal to the threshold, and / or, the cell supports slices (for example, whether the slices supported by other cells / SSB-less cells match / include / equal to the slices required by the UE), determine whether to perform cell reselection or reselect the corresponding SSB-less cell (or other cells). Optionally, other cells are based on the first signal or SSB measurement, or the measurement results of other cells are based on the first signal or SSB. Optionally, the measurement result based on the first signal itself or a variant thereof (such as making certain changes or corrections) is compared with the measurement result based on the SSB. Optionally, the measurement result based on the first measurement satisfies the R criterion and / or the S criterion or the cell reselection criterion before access to the SSB-less cell is possible. For example, if the UE detects that the first signal and / or the channel quality of the first signal is greater than or equal to a threshold, the UE determines whether to perform cell reselection or whether to reselect the corresponding SSB-less cell. For example, the UE sends a first request message based on the first signal, or the UE detects that the first signal and / or the channel quality of the first signal is greater than a threshold, requesting the SSB-less cell to be converted to a non-energy-saving / normal state, or requesting at least one of the SSB / SIB / paging of the SSB-less cell. Then, the UE requests whether to reselect the SSB-less cell. (For example, the above is performed based on the first signal when the R and / or S criteria are met). For example, if a NES-cell can be potentially a candidate to camp, then the UE sends UL-WUS to check if it can be camped on. As an implementation manner, the UE accesses the network from an anchor cell or other non-SSB-less cell. Further, optionally, when the sixth condition is met, the connected UE switches or redirects to the SSB-less cell, and / or transmits with the SSB-less cell. The sixth condition is at least one of the following: the connected UE does not have CA / DC capability. The channel quality between the connected UE and the anchor cell is less than a threshold, the channel quality between the UE and the SSB-less cell is greater than a threshold, the UE detects the SSB-less cell, or the UE has data to be transmitted (such as according to the data to be transmitted information of the LCH, or there is a service request), or the slice supported by the SSB-less cell matches the slice required by the UE (such as the same or included), the amount of data to be transmitted by the UE is greater than the threshold, the UE is within the coverage of the SSB-less cell, the anchor cell instructs the UE to switch or rediret to the SSB-less cell / transmit with the SSB-less cell, obtains the SSB-less cell RACH information, and detects the SSB-less cell. Further, for example, if the UE switches or redirects to an SSB-less cell, the UE obtains system information from the SSB-less cell and / or performs paging. Further, for example, when the UE switches to or rediects to an SSB-less cell, the UE works in the SSB-less cell and the cell / anchor cell before the switch in a TDM manner, for example, periodically or TDM-acquires paging or updated system information from the cell / anchor cell before the switch. Further, for example, after switching, the UE obtains the system information of the SSB-less cell through the dedicated RRC. Optionally, when the seventh condition is met, the connected UE transmits with the anchor cell and the SSB-less cell simultaneously, that is, the SSB-less cell serves as a secondary cell. The seventh condition is at least one of the following: the connected UE has CA / DC capability. The channel quality between the connected UE and the anchor cell is less than or equal to the threshold, the channel quality between the UE and the SSB-less cell is greater than the threshold, the UE detects the SSB-less cell, or the UE has data to be transmitted (such as according to the data to be transmitted information of the LCH, or there is a service request), or the slice supported by the SSB-less cell matches the slice required by the UE (such as being the same or containing), the amount of data to be transmitted by the UE is greater than the threshold, the UE is within the coverage of the SSB-less cell, the anchor cell instructs the UE to transmit with the SSB-less cell, and the anchor cell connects the SSB-less cell to the SSB-less cell. Add or activate the Scell ​​for the UE, obtain the SSB-less cell RACH information, and detect the SSB-less cell. Further, for example, the UE obtains system information (of the SSB-less cell) and / or paging from the anchor cell. Further, for example, the UE obtains the system information of the SSB-less cell through a dedicated RRC. Optionally, when the eighth condition is met, the connected UE receives system information update / paging (such as fixed time and / or fixed location) in the anchor cell and transmits (such as data transmission, feedback, etc.) with the SSB-less cell. The eighth condition is at least one of the following: the connected UE does not have CA / DC capability. The channel quality between the Connected UE and the anchor cell is less than or equal to the threshold, the channel quality between the UE and the SSB-less cell is greater than the threshold, the UE detects the SSB-less cell, the amount of data to be transmitted by the UE is greater than the threshold, or the UE has data to be transmitted (such as according to the information of the data to be transmitted on the LCH, or there is a service request), or the slice supported by the SSB-less cell matches the slice required by the UE (such as the same or included), the UE is within the coverage of the SSB-less cell, the SSB-less cell does not send some or all of the public information (such as paging, SSB, SIB), the SSB-less cell is in energy-saving mode, the anchor cell indicates transmission with the SSB-less cell, the SSB-less cell RACH information is obtained, and the SSB-less cell is detected. As an implementation method, the UE uses the RACH configuration of the SSB-less cell to synchronize with the SSB-less cell. Optionally, the UE receives the PDCCH in the SSB-less cell within a second time period, and / or performs transmission with the SSB-less cell. Optionally, the UE receives the PDCCH in the SSB-less cell and / or performs transmission with the SSB-less cell before the transmission of the transmission resources of the SSB-less cell obtained from the anchor cell or the transmission is completed. Optionally, the UE falls back to the anchor cell to obtain new transmission resources of the SSB-less cell or transmits in the anchor cell after the second time period, or when there are no available transmission resources after obtaining the transmission resources of the SSB-less cell from the anchor cell, or after the transmission resources are completed. As an implementation method, the SSB-less cell does not send paging information. Correspondingly, the UE obtains paging information on other cells such as an anchor cell. Optionally, the anchor cell is indicated by the first signal or the second information or the third information. As an implementation method, the SSB-less cell uses a specific configuration or location to send paging information. Optionally, the location or configuration of the paging is a fixed interval, or a fixed relationship between the first signal, the second information, or the third information resource. Optionally, the paging location appears periodically, or the paging location has an on / off pattern. Optionally, the UE monitors at all paging locations, that is, the time when the UE monitors the paging is independent of the UE ID. The embodiments of the present application solve the problem of how a UE communicates with an SSB-less cell when the SSB-less cell cannot work independently. The following describes methods for configuring, activating, deactivating, and feeding back cell-level DTX / DRX configuration information in conjunction with Embodiment 4. Embodiment 4 As an implementation manner, the network device may configure the cell DTX / DRX configuration. Optionally, the cell DTX / DRX configuration is applied to idle / inactive / connected UE. Optionally, the cell DTX / DRX configuration is notified to the cell or UE via common RRC or system information. Optionally, the cell DTX / DRX configuration is updated through a system information update (SI-update) process, or updated through indication information carried by a dedicated DCI (optionally, a DCI of a specific RNTI may be used). Optionally, for the non-active time period of cell DTX / DRX, at least one of paging / SSB / SIB / RACH may not be sent / transmitted. For example, the network does not send at least one of SSB / SIB / paging, and / or does not receive or respond to RACH. For example, the UE does not receive at least one of SSB / SIB / paging, and / or does not send or perform a RACH process. Optionally, for a cell with cell DTX / DRX, or for cell DTX / DRX non-active, the UE behavior may be at least one of the following: delaying TX / RX transmission and / or reception. Sending a first request signal considers the cell to be a barred cell. Optionally, the first request signal is used to trigger the network to leave cell DTX / DRX non-active, or to deactivate / deconfigure cell DTX / DRX, or to use another set of cell DTX / DRBs. Or the first request signal is used to convert to a non-energy-saving mode or state. For example, if the cell is considered to be a barred cell, the barred time may be 300s, or the barred time may be a predefined or configured or specific duration, or the barred time may be a time period of cell DTX / DRX non-active (if the time period is multiple or periodic, one or each is considered to be a barred time period). As an implementation manner, the network device may activate or deactivate the cell DTX / DRX configuration. Optionally, configuring cell DTX / DRX means activating cell DTX / DRX, and deconfiguring means deactivating cell DTX / DRX. Alternatively, cell DTX / DRX configuration is activated or deactivated by dedicated signaling. Optionally, the dedicated signaling may be DCI or MAC CE. Optionally, the dedicated signaling indicates whether cell DTX / DRX is activated / deactivated, and / or which set of cell DTX / DRX is activated / deactivated. Optionally, the dedicated signaling may be RRC, that is, configuring or activating the cell DTX / DRX configuration, or, while configuring, indicating in an RRC message whether the cell DTX / DRX is activated / deactivated, and / or which set of cell DTX / DRX is activated / deactivated. For example, the cell DTX / DRX configuration may be one or more sets. Optionally, the NW may instruct the UE to activate or deactivate one set of cell DTX / DRX configurations from the multiple sets. Alternatively, the network instructs the UE to activate or deactivate one set of configured cell DTX / DRX configurations. For example, when there are multiple sets of cell DTX / DRX configurations, the cell may activate or use only one set of cell DTX / DRX configurations, or the cell may simultaneously activate or use multiple sets of cell DTX / DRX (different cell DTX / DRX are used simultaneously / superimposedly). Alternatively, the cell may activate or use multiple sets of cell DTX / DRX configurations at the same time. The same cell DTX / DRX is activated or used for different UEs, or the same cell DTX / DRX is activated or used differently for different UEs (for example, for different UE types, for different UE QoS requirements, for idle / inactive or connected UEs). For example, the cell DTX / DRX configuration may be broadcast in system information. For example, the cell DTX / DRX configuration may be indicated in a dedicated RRC message. Optionally, the dedicated RRC message may be a group message or a UE-specific RRC message. For example, if both the system information (or common RRC) and the dedicated RRC receive the cell DTX / DRX configuration, the UE prioritizes or uses the cell DTX / DRX configuration carried by the dedicated RRC. For example, if both the system information (or common RRC) and the UE-specfic RRC receive the cell DTX / DRX configuration, the UE prioritizes or uses the cell DTX / DRX configuration carried by the UE-specfic RRC. For example, if there are multiple ways (such as one or more indication ways among common RRC, SIB, system information, dedicated RRC, UE-specific RRC, dedicated MAC CE, common DCI, and UE-specific DCI) to activate or deactivate cell DTX / DRX, the UE activates or deactivates cell DTX / DRX according to the latest indication information, or the UE activates or deactivates cell DTX / DRX according to the indication of the highest priority signaling (optionally, the priority may be a default (for example, dedicated is higher than common, or UE-specific is higher than common, or UE-specific is higher than other dedicated, or vice versa), or it may be indicated by the network, or it may be predefined), or the UE activates or deactivates cell DTX / DRX using the indication of dedicated signaling (such as dedicated RRC, UE-specific RRC, dedicated MAC CE, common DCI, or UE-specific DCI), or the UE activates or deactivates cell DTX / DRX according to the indication of UE-specific signaling (such as UE-specific RRC, or dedicated MAC CE, or UE-specific DCI). DTX / DRX, or, activate or deactivate cell DTX / DRX according to the latest indication information after the first duration used by the previous indication information (for example, the previous indication information indicates cell DTX / DRX activation, and the UE can only update the cell DTX / DRX activation / deactivation after the first duration used or sent by the indication information, or the UE can only activate / deactivate cell DTX / DRX according to the latest indication information, even if the latest indication information is received within or after the first duration). For example, in the case where there are multiple sets of cell DTX / DRX configurations, if different indication information activates or deactivates different cell DTX / DRX configurations, the UE follows each indication information, activates or deactivates the corresponding cell DTX / DRX configuration or maintains the cell DTX / DRX activation / deactivation state; or, the UE only follows the latest indication information, activates or deactivates the cell DTX / DRX configuration corresponding to the latest indication information or maintains the cell DTX / DRX activation / deactivation state (optionally, deactivates other cell DTX / DRX configurations); or, the UE only follows the UE-specific indication information, activates or deactivates the cell DTX / DRX configuration corresponding to the latest indication information or maintains the cell DTX / DRX activation / deactivation state (optionally, deactivates other cell DTX / DRX configurations); or, the UE only follows the dedicated indication information, activates or deactivates the cell DTX / DRX configuration corresponding to the latest indication information or maintains the cell DTX / DRX activation / deactivation state (optionally, deactivates other cell DTX / DRX configurations). or, the UE only follows the indication information with the highest priority, activates or deactivates the cell DTX / DRX configuration corresponding to the latest indication information or maintains the cell DTX / DRX activation / deactivation state (optionally, deactivates other cell DTX / DRX configurations). For example, in the case where there are multiple sets of cell DTX / DRX configurations, if different indication information activates or deactivates the same cell DTX / DRX configuration, the UE follows each indication information, activates or deactivates the corresponding cell DTX / DRX configuration or maintains the cell DTX / DRX activation / deactivation state; or, the UE only follows the latest indication information, activates or deactivates the cell DTX / DRX configuration corresponding to the latest indication information or maintains the cell DTX / DRX activation / deactivation state (optionally, deactivates other cell DTX / DRX configurations); or, the UE only follows the UE-specific indication information, activates or deactivates the cell DTX / DRX configuration corresponding to the latest indication information or maintains the cell DTX / DRX activation / deactivation state (optionally, deactivates other cell DTX / DRX configurations); or, the UE only follows the dedicated indication information, activates or deactivates the cell DTX / DRX configuration corresponding to the latest indication information or maintains the cell DTX / DRX activation / deactivation state (optionally, deactivates other cell DTX / DRX configurations); or, the UE only follows the indication information with the highest priority, activates or deactivates the cell DTX / DRX configuration corresponding to the latest indication information or maintains the cell DTX / DRX activation / deactivation state (optionally, deactivates other cell DTX / DRX configurations). For example, the dedicated signaling may be UE group common, cell common, or UE-specific. For example, the dedicated signaling may be sent repeatedly. For example, the dedicated signaling may be repetitioned N times. Optionally, the N times may be preconfigured or indicated by scheduling. For example, the dedicated signaling carries an identifier of the cell DTX / DRX, such as an index. For example, the dedicated information indicates activation / deactivation of a cell DTX / DRX, or indicates activation / deactivation of a group or a set of cell DTX / DRX, or indicates activation / deactivation of multiple cell DTX / DRX. For example, dedicated information indicates activation and deactivation of one or more cell DTX / DRX. For example, indicates activation of at least one cell DTX / DRX, and indicates deactivation of at least one cell DTX / DRX. For example, the dedicated information only indicates activation or deactivation of one or more cell DTX / DRX. For example, only indicates activation of at least one cell DTX / DRX, or only indicates deactivation of at least one cell DTX / DRX. As an implementation, for activation or deactivation of cell DTX / DRB, the UE performs feedback. The UE performs feedback for dedicated signaling of the active cell DTX / DRX configuration. Optionally, the UE performs feedback for signaling indication of activation or deactivation of the cell DTX / DRX configuration. Optionally, the dedicated signaling may be common signaling. Optionally, the UE uses MAC CE to feedback whether a signaling for activating or deactivating the cell DTX / DRX configuration is received. Optionally, the signaling is one or more of the above signalings. Optionally, the signaling may be PDCCH. Optionally, the MAC CE is of a fixed size, and / or the MAC CE carries information corresponding to all cell DTX / DRX configurations. For example, a bitmap is used to indicate whether the activation / deactivation information corresponding to all cell DTX / DRX configurations is received (for example, 1 represents received, and 0 represents not received). For example, the index of the cell DTX / DRX indicated by the received activation / deactivation information is indicated by feedback. For example, the MAC CE is of a fixed size, and / or the MAC CE carries information corresponding to all cell DTX / DRX configurations. For example, a bitmap is used to indicate whether the PDCCH corresponding to all cell DTX / DRX configurations is received (for example, 1 represents received, and 0 represents not received). For example, the index of the cell DTX / DRX of the received PDCCH is indicated by feedback. For example, the MAC CE is of a fixed size, and / or the MAC CE carries information corresponding to all cell DTX / DRX configurations. For example, a bitmap is used to indicate whether all cell DTX / DRX configurations are activated or deactivated (for example, 1 represents activation, and 0 represents deactivation). For example, an index of the cell DTX / DRX involved is indicated by feedback. For example, the MAC CE is of a variable size and / or carries information corresponding to the cell DTX / DRX configuration corresponding to the received PDCCH. Optionally, the feedback information carries an index of the cell DTX / DRX configuration corresponding to the PDCCH. For example, the MAC CE is of variable size, and / or carries information corresponding to the cell DTX / DRX configuration of the activation / deactivation state change. Optionally, the feedback information carries the index of one or more cell DTX / DRX configurations, or carries a bitmap indicating the cell DTX / DRX information of the activation / deactivation state change (such as 1, representing activation or state change, or 0, representing deactivation or no state change). For example, the MAC CE is of variable size, and / or carries information corresponding to the cell DTX / DRX configuration indicated by the activation / deactivation indication signaling. Optionally, the feedback information carries one or more indexes of cell DTX / DRX configurations, or carries a bitmap indicating the cell DTX / DRX information indicated by the activation / deactivation indication signaling (such as 1, representing activation or signaling received, or 0, representing deactivation or signaling not received). For example, the UE uses MAC CE to feed back the activation or deactivation status of the cell DTX / DRX. Optionally, the feedback information carries information of the cell DTX / DRX configuration corresponding to the PDCCH (such as an identifier and / or status and / or PDCCH reception status). For example, the MAC CE is of a fixed size, and / or carries information corresponding to all cell DTX / DRX configurations. For example, indicates the status and / or identifier of all cell DTX / DRX configurations. For example, indicates whether all cell DTX / DRX configurations are activated or deactivated (for example, 1 represents activation, and 0 represents deactivation) through a bitmap. For example, indicates the index of the activated or deactivated cell DTX / DRX through feedback, and / or the activation / deactivation status. For example, the MAC CE is of a fixed size, and / or carries information corresponding to a specific or a cell DTX / DRX configuration. For example, a bitmap is used to indicate whether a specific or a cell DTX / DRX configuration is activated or deactivated (for example, 1 represents activation, and 0 represents deactivation). For example, the index of the activated or deactivated cell DTX / DRX is indicated by feedback, and / or the activation / deactivation status. For example, the MAC CE is of variable size and / or carries information corresponding to the cell DTX / DRX configuration corresponding to the received PDCCH. Optionally, the feedback information carries an index of the cell DTX / DRX configuration corresponding to the PDCCH and / or an activation / deactivation state of the corresponding cell DTX / DRX. Optionally, the UE uses MAC CE to feedback the activation or deactivation status of the cell DTX / DRX. Optionally, the feedback information carries information of the cell DTX / DRX configuration indicated by the activation / deactivation signaling (such as an identifier and / or status and / or reception status of the activation / deactivation signaling). For example, the MAC CE is of a fixed size, and / or carries information corresponding to all cell DTX / DRX configurations.
