[0089] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, rather than all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0090] The "and / or" in the present application is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article indicates that the associated objects before and after are in an "or" relationship.

[0091] "At least one" in the present application means one or more. "Multiple" means two or more.

[0092] "At least one (item) of the following" or its similar expressions in the present application refer to any combination of these items, including any combination of single item (s) or plural item (s). For example, at least one (item) of a, b, or c may represent: a, b, c, a and b, a and c, b and c, or a, b, and c, where each of a, b, and c itself may be an element or a set containing one or more elements.

[0093] In this application, the descriptions such as first and second are only used for indicating and distinguishing the described objects, without any order, nor do they represent any special limitation on the number of objects in the embodiments of this application, and they cannot constitute any limitation on the embodiments of this application. For example, the first SSB refers to the SSB sent on the first cell, and the second SSB refers to the SSB sent on the second cell. The use of the first SSB and the second SSB is only to distinguish different SSBs, rather than indicating differences in the priority or importance of these two SSBs, etc.

[0094] In this application, terms such as "exemplary", "in some embodiments", and "in other embodiments" are used to give examples, illustrations, or explanations. Any embodiment or design solution described as "exemplary" in this application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of the term "exemplary" is intended to present concepts in a specific manner.

[0095] For ease of understanding, the concepts involved in the embodiments of this application will be described first.

[0096] 1. Anchor cell

[0097] In a communication network, a cell that provides wide coverage is called an anchor cell, and can also be called an anchor carrier, a first type of carrier, a first type of cell, a primary carrier, or a primary cell (PCell).

[0098] 2. Non-anchor cell

[0099] In a communication network, a cell with a smaller coverage area that provides high-speed data transmission services and can be turned off or enter a sleep state according to the network load is called a non-anchor cell. When the cell is turned off or in a sleep state, it does not send system information. A non-anchor cell can also be called a non-anchor carrier, a second type of carrier, a second type of cell, a secondary carrier, or a secondary cell (SCell).

[0100] 3. Random access procedure

[0101] The terminal can achieve synchronization and obtain the master information block (MIB) by receiving the SSB. The terminal determines the reception resources and related configuration parameters of the system information block (SIB)1 through the MIB.

[0102] The random access procedure is as follows Figure 1 As shown, the terminal first completes downlink synchronization by reading the MIB and SIB1. By reading SIB1, the terminal determines the resources for sending a preamble to the network device to indicate its intention to access the network, and the terminal sends a random access preamble (i.e., Message 1) to the network device. If the network device correctly receives Message 1, it will send a random access response message (i.e., Message 2) scrambled with a random access radio network temporary identity (RA-RNTI) to the terminal. After sending Message 1, the terminal can use the RA-RNTI to monitor Message 2 from the network device to descramble the message.

[0103] Message 2 may include a timing advance (TA), a temporary cell radio network temporary identity (TC-RNTI), power adjustment, and an indication of the resources for the terminal to send Message 3. Then, the terminal sends its identity and a radio resource control (RRC) connection request (i.e., Message 3) to the network device through the uplink scheduling indication in Message 2. Finally, the network device can notify the terminal of the completion of the initial access procedure through Message 4, otherwise, the terminal can determine that the initial access procedure has failed.

[0104] Through the SIB1 message, the terminal can obtain the relevant configuration of the physical random access channel transmission occasion (RO), including the period size of RO, the number of ROs in the time domain within a physical random access channel (PRACH) period, the number of ROs multiplexed in the frequency domain, the number of SSBs associated with each RO, etc.

[0105] For the network device, the network device needs to continuously detect Message 1 sent by the terminal on the configured RO resources to ensure that it can receive Message 1 sent by the terminal in a timely manner.

[0106] 4. Network Device

[0107] A network device is a device with wireless transceiver functions. It includes, but is not limited to: an evolved Node B (eNB or eNodeB) in Long Term Evolution (LTE), a base station (gNodeB or gNB) or a Transmission and Receiving Point (TRP) in New Radio (NR), a base station in a subsequent evolved system, an access node in a Wireless Fidelity (WiFi) system, a wireless relay node, a wireless backhaul node, etc. The base station can be: a macro base station, a micro base station, a pico base station, a small station, a relay station, or a balloon station, etc. Multiple base stations can support the network of the same technology mentioned above, or can also support the networks of different technologies mentioned above. The base station can include one or more co-located or non-co-located TRPs.

[0108] 5. Terminal

[0109] A terminal is a device with wireless transceiver functions. The terminal can be deployed on land, including indoor or outdoor, handheld, wearable or vehicle-mounted; it can also be deployed on the water surface (such as a ship, etc.); it can also be deployed in the air (such as an airplane, a balloon, a satellite, etc.). The terminal can be a mobile phone, a tablet (pad), a computer with wireless transceiver functions, a virtual reality (VR) terminal device, an augmented reality (AR) terminal, a wireless terminal in industrial control, a vehicle-mounted terminal, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, a wearable terminal, etc. The terminal involved in the embodiments of the present application can also be referred to as a user equipment (UE), an access terminal, a vehicle-mounted terminal, an industrial control terminal, a UE unit, a UE station, a mobile station, a mobile unit, a remote station, a remote user equipment, a mobile device, a wireless communication device, a UE agent, or a UE device, etc. The terminal can also be fixed or mobile.

[0110] For ease of understanding, the following is combined with Figure 2 , to illustrate the application scenarios applicable to the embodiments of the present application.

[0111] Figure 2A schematic diagram of an application scenario provided by an embodiment of this application. Please refer to Figure 2 , including network device 201, network device 202, network device 203, network device 204, and terminal 205.

[0112] The area covered by network device 201 is the anchor cell. The areas covered by network devices 202, 203, and 204 are non-anchor cells. Network devices 202, 203, and 204 are located within the coverage area of network device 201 and are controlled by network device 201, and can be turned on or off as needed. Terminal 205 can establish a connection relationship with any one of network devices 201, 202, 203, and 204. Network devices 202, 203, and 204 can provide high-speed data transmission services for terminal 205 within their respective coverage areas.

[0113] Network device 201 needs to carry the master information block (MIB) and system information block (SIB) 1 to support cell search and system information transmission. If network devices 202, 203, or 204 are only used for data load balancing, they do not need to carry MIB and SIB1; if they need to support paging, random access, and radio resource management (RRM) measurements, etc., they still need to carry MIB and SIB to support the terminal for time-frequency synchronization and RRM measurement.

[0114] Figure 2 It is only a schematic diagram of an application scenario and does not constitute a limitation on the application scenario of the technical solution provided by this application.

[0115] In view of the technical problems proposed in the background art, an embodiment of this application provides a communication method. The network device corresponding to the first cell can configure the configuration parameters of the uplink indication signal for the terminal, so that the terminal can send the uplink indication signal to the network device corresponding to the second cell based on the configuration parameters, to trigger the network device corresponding to the second cell to send the first system information on the second cell. The network device corresponding to the second cell can send the first system information as needed, reducing the static power consumption of the network device corresponding to the second cell.

[0153] (13) Time domain start position of the uplink indication signal, number of time units occupied by the uplink indication signal and period of the uplink indication signal.

[0154] It should be noted that the above time domain parameters are only examples, and the present application does not limit the time domain parameters.

[0155] The time domain offset is a positive value.

[0156] In a possible implementation, each configuration parameter may further include the sequence or format of the uplink indication signal. For example, the format may be a preamble range.

[0157] In a possible implementation, if the first cell is different from the second cell, the configuration information may further include the identifier of the second cell, and each identifier of the second cell corresponds to a configuration parameter of the uplink indication signal.

[0158] The indication information may be used to indicate whether the network device corresponding to the second cell sends the first system information on the second cell.

[0159] If the second cell is different from the first cell, the first information may include one or more indication messages, and one indication message is used to indicate whether to send the first system information on one second cell.

[0160] In a possible implementation, if the first cell is different from the second cell, each indication message may further include an identifier of the second cell.

[0161] S302. The network device corresponding to the first cell sends the first information to the terminal on the first cell.

[0162] Correspondingly, the terminal receives the first information sent by the network device corresponding to the first cell on the first cell.

[0163] If the first information includes configuration information and indication messages, the network device corresponding to the first cell may send the configuration information and the indication messages to the terminal on the first cell simultaneously, or may send the configuration information and the indication messages to the terminal on the first cell separately.

[0164] S303. The terminal communicates with the network device corresponding to the second cell based on the first information.

[0165] If the first information includes configuration information, the terminal may send an uplink indication signal to the network device corresponding to the second cell on the second cell based on the configuration information.

[0166] In this case, if the second cell is different from the first cell, and the configuration information includes configuration parameters of uplink indication signals of multiple second cells, after receiving the configuration information, the terminal determines an access cell among the multiple second cells. The access cell may be a cell in the multiple second cells whose reference signal quality is greater than or equal to a preset threshold or satisfies the cell reselection criterion. Then, the terminal sends an uplink indication signal on the access cell based on the configuration parameters of the uplink indication signal of the access cell.

[0167] If the first information includes indication messages, and the indication messages indicate that the network device corresponding to the second cell sends the first system information on the second cell, the terminal may receive the first system information sent by the network device corresponding to the second cell on the second cell based on the indication messages.

[0168] In this case, if the second cell is different from the first cell, and the first information includes multiple indication messages, and the multiple indication messages indicate to send the first system information, the terminal may receive the first system information on the multiple second cells.

[0169] If the first information includes configuration information and indication information, and the indication information indicates that the network device corresponding to the second cell does not transmit the first system information on the second cell, the terminal may send an uplink indication signal to the network device corresponding to the second cell on the second cell based on the configuration information.

[0170] In this case, if the second cell is different from the first cell, and the first information includes configuration parameters and indication information of uplink indication signals of multiple second cells, and if the multiple indication information indicates not to transmit the first system information, after receiving the first information, the terminal determines an access cell among the multiple second cells. The access cell may be a cell among the multiple second cells whose reference signal quality is greater than or equal to a preset threshold or satisfies the cell reselection criterion. The terminal then sends an uplink indication signal on the access cell based on the configuration parameters of the uplink indication signal of the access cell.

[0171] In Figure 3 In the embodiment shown, the network device corresponding to the first cell determines the first information. The first information includes configuration information and / or indication information. The configuration information includes configuration parameters of the uplink indication signal, and the uplink indication signal is used to trigger the network device corresponding to the second cell to transmit the first system information on the second cell; the indication information is used to indicate whether to transmit the first system information on the second cell; the first information is sent to the terminal on the first cell, and the terminal communicates with the network device corresponding to the second cell based on the first information. The network device corresponding to the second cell may send the first system information as needed, reducing the static power consumption of the network device corresponding to the second cell.

[0172] In Figure 3 Based on the embodiment shown, the communication method of the present application is described in different scenarios below.

[0173] Figure 4 It is a schematic flowchart of another communication method provided by an embodiment of the present application. As Figure 4 shown, taking the first cell and the second cell as the same cell as an example, for convenience of description, the first cell and the second cell are hereinafter referred to as the target cell, and the network device corresponding to the first cell and the network device corresponding to the second cell are hereinafter simply referred to as the network device. The method includes:

[0174] S401. The network device determines the first information, where the first information includes configuration information and / or indication information.

[0175] It should be noted that the execution process of S401 may refer to the execution process of S301, which will not be elaborated here. The only thing to note is that the first SSB and the second SSB are the same SSB, and the first SSB and the second SSB are hereinafter simply referred to as the SSB.

[0176] S402. The network device sends an SSB to the terminal on the target cell, and the SSB includes first information.

[0177] Correspondingly, the terminal receives the SSB sent by the network device on the target cell.

[0178] In a possible implementation, the first information is carried in the MIB of the SSB.

[0179] In a possible implementation, the indication information is carried in the SSB subcarrier offset field of the MIB.

[0180] In a possible implementation, the indication information is carried in one bit of the MIB. That is, a bit can be set in the MIB to indicate whether the network device sends the first system information on the target cell.

[0181] In a possible implementation, if the indication information indicates that the network device does not send the first system information on the target cell, the MIB includes configuration information; if the indication information indicates that the network device sends the first system information on the target cell, the MIB does not include configuration information.

[0182] For example, a bit is set in the MIB of the SSB to indicate whether the network device sends SIB1 on the target cell. If this bit indicates that the network device does not send SIB1 on the target cell, the MIB includes configuration information; if this bit indicates that the network device sends SIB1 on the target cell, the MIB does not include configuration information. At this time, the terminal can determine the relevant reception parameters of SIB1 through the MIB.

[0183] For another example, the value of the SSB subcarrier offset field in the MIB of the SSB is used to indicate whether the network device sends SIB1 on the target cell; when the value of the SSB subcarrier offset field in the MIB of the SSB takes a special value (for example, FR1 takes 1111), it indicates that the network device does not send SIB1 on the target cell, and the MIB includes configuration information; when the value of the SSB subcarrier offset field in the MIB of the SSB takes a normal value (for example, FR1 takes 11111), it indicates that the network device sends SIB1 on the target cell, and the MIB does not include configuration information.

[0184] In a possible implementation, if the indication information indicates that the network device does not send the first system information on the target cell, the remaining minimum system information (RMSI)-physical downlink control channel (PDCCH) configuration field in the MIB is used to configure the configuration information; if the indication information indicates that the network device sends the first system information on the target cell, the RMSI-PDCCH configuration field in the MIB is used to configure the RMSI-PDCCH monitoring parameters.

[0185] For example, a bit in the MIB of the SSB is set to indicate whether the network device sends SIB1 on the target cell. If this bit indicates that the network device does not send SIB1 on the target cell, the RMSI-PDCCH configuration field in the MIB can be used to configure the configuration information; if this bit indicates that the network device sends SIB1 on the target cell, the configuration information is not included in the MIB. At this time, the RMSI-PDCCH configuration field can be used to configure the RMSI-PDCCH monitoring parameters.

[0186] For another example, the value of the SSB subcarrier offset field in the MIB of the SSB is used to indicate whether the network device sends SIB1 on the target cell; when the value of the SSB subcarrier offset field in the MIB of the SSB takes a special value (for example, 1111 for FR1), it indicates that the network device does not send SIB1 on the target cell, and the RMSI-PDCCH configuration field in the MIB can be used to configure the configuration information; when the value of the SSB subcarrier offset field in the MIB of the SSB takes a normal value (for example, 11111 for FR1), it indicates that the network device sends SIB1 on the target cell, and the configuration information is not included in the MIB. At this time, the RMSI-PDCCH configuration field can be used to configure the RMSI-PDCCH monitoring parameters.

[0187] S403. The terminal communicates with the network device based on the first information.

[0188] It should be noted that the execution process of S403 can refer to the execution process of S303, which will not be elaborated here. The following details how to send the uplink indication signal to the network device based on the configuration parameters of the uplink indication signal.

[0189] The time domain position of the uplink indication signal can be determined based on the time domain parameters of the uplink indication signal, and the frequency domain position of the uplink indication signal can be determined based on the frequency domain position of the uplink indication signal. The uplink indication signal can be sent at the determined time-frequency position, and the format or sequence of the uplink indication signal can be the format or sequence indicated in the configuration parameters.

[0190] The following separately describes how to determine the frequency-domain position of the uplink indication signal based on the frequency-domain parameters of different uplink indication signals.

[0191] (1) If the frequency-domain parameters of the uplink indication signal include the frequency-domain bandwidth of the uplink indication signal, the terminal can determine the frequency-domain starting position of the SSB in the target cell by detecting the SSB sent by the network device on the target cell, determine the frequency-domain starting position of the SSB in the target cell as the frequency-domain starting position of the uplink indication signal, and determine the frequency-domain position of the uplink indication signal based on the frequency-domain starting position and frequency-domain bandwidth of the uplink indication signal.

[0192] For example, the frequency-domain position of the uplink indication signal can be as Figure 5A shown.

[0193] In this method, if the frequency-domain parameters of the uplink indication signal further include the subcarrier spacing, the indicated subcarrier spacing can be used as the subcarrier spacing of the uplink indication signal; if the frequency-domain parameters of the uplink indication signal do not include the subcarrier spacing, the subcarrier spacing of the SSB in the target cell can be used as the subcarrier spacing of the uplink indication signal.

[0194] (2) If the frequency-domain parameters of the uplink indication signal include the frequency-domain bandwidth and frequency-domain offset of the uplink indication signal, the terminal can determine the frequency-domain starting position of the SSB in the target cell by detecting the SSB sent by the network device on the target cell, determine the frequency-domain starting position of the uplink indication signal based on the frequency-domain starting position and frequency-domain offset of the SSB in the target cell, and determine the frequency-domain position of the uplink indication signal based on the frequency-domain starting position and frequency-domain bandwidth of the uplink indication signal.

[0195] For example, the frequency-domain position of the uplink indication signal can be as Figure 5B or Figure 5C shown.

[0196] In this method, if the frequency-domain parameters of the uplink indication signal further include the subcarrier spacing, the indicated subcarrier spacing can be used as the subcarrier spacing of the uplink indication signal; if the frequency-domain parameters of the uplink indication signal do not include the subcarrier spacing, the subcarrier spacing of the SSB in the target cell can be used as the subcarrier spacing of the uplink indication signal.

[0197] (3) If the frequency-domain parameters of the uplink indication signal include the frequency-domain starting position and frequency-domain bandwidth of the uplink indication signal, the terminal can determine the frequency-domain position of the uplink indication signal based on the frequency-domain starting position and frequency-domain bandwidth of the uplink indication signal.

[0198] In this method, if the frequency-domain parameter of the uplink indication signal further includes the subcarrier spacing, the indicated subcarrier spacing can be used as the subcarrier spacing of the uplink indication signal; if the frequency-domain parameter of the uplink indication signal does not include the subcarrier spacing, the subcarrier spacing of the SSB of the target cell can be used as the subcarrier spacing of the uplink indication signal.

[0199] It should be noted that the above frequency-domain parameters of the uplink indication signal are only examples. If there are other unexemplified cases for the frequency-domain parameters of the uplink indication signal, the frequency-domain position of the uplink indication signal can be determined with reference to the method in the above examples.

[0200] The following separately describes how to determine the frequency-domain position of the uplink indication signal based on different time-domain parameters of the uplink indication signal.

[0201] (1) If the time-domain parameter of the uplink indication signal includes the time-domain start position indication information of the uplink indication signal, the period indication information of the uplink indication signal, and the time-domain offset, the terminal can determine a reference SSB among multiple SSBs according to the time-domain start position indication information of the uplink indication signal, then determine the time-domain start position of the uplink indication signal according to the time-domain end position of the reference SSB and the time-domain offset, then determine the period of the uplink indication signal according to the period of the SSB of the target cell and the period indication information of the uplink indication signal, and finally determine the time-domain position of the uplink indication signal according to the time-domain start position of the uplink indication signal, the period of the uplink indication signal, and the number of time units occupied by the uplink indication signal predefined by the protocol.

[0202] For example, the position of the uplink indication signal in the time domain can be as Figure 6A shown. In Figure 6A , taking the first detected SSB as the reference SSB, the period indication information of the uplink indication signal indicates that the period of the uplink indication signal is twice the period of the SSB.

[0203] In this method, if the time-domain parameters of the uplink indication signal further include the number of time units occupied by the uplink indication signal, the number of time units occupied by the indicated uplink indication signal can be used to determine the time-domain position of the uplink indication signal in the above manner; if the granularity of the time-domain offset is a time slot, the time-domain start position indication information of the uplink indication signal can further indicate the start symbol of the uplink indication signal. For example, if it is determined that the time-domain start position of the uplink indication signal is in the first time slot according to the time-domain end position of the reference SSB and the time-domain offset, the start symbol of the uplink indication signal can be determined in the first time slot according to the time-domain start position indication information of the uplink indication signal; if the time-domain start position indication information of the uplink indication signal does not indicate the start symbol of the uplink indication signal, the start symbol of the uplink indication signal can be determined according to the start symbol predefined by the protocol. For example, the first symbol of the first time slot can be determined as the start symbol of the uplink indication signal; if the time-domain parameters of the uplink indication signal do not include the period indication information of the uplink indication signal, the period of the SSB of the target cell can be used as the period of the uplink indication signal to determine the time-domain position of the uplink indication signal in the above manner.

[0204] (2) If the time-domain parameters of the uplink indication signal include the time-domain offset of the uplink indication signal, the terminal can determine the time-domain start position of the uplink indication signal according to the time-domain end position of the SSB of the target cell and the time-domain offset, use the period of the SSB of the target cell as the period of the uplink indication signal, and then determine the time-domain position of the uplink indication signal according to the time-domain start position of the uplink indication signal, the period of the uplink indication signal, and the number of time units occupied by the uplink indication signal predefined by the protocol.

[0205] For example, the position of the uplink indication signal in the time domain can be as Figure 6B shown.

[0206] In this manner, if the time-domain parameter of the uplink indication signal further includes the number of time units occupied by the uplink indication signal, the number of time units occupied by the indicated uplink indication signal can be used to determine the time-domain position of the uplink indication signal in the above manner; if the time-domain parameter of the uplink indication signal further includes the period of the uplink indication signal, the indicated period of the uplink indication signal can be used to determine the time-domain position of the uplink indication signal in the above manner; if the granularity of the time-domain offset is a time slot, the time-domain start position indication information of the uplink indication signal can further indicate the start symbol of the uplink indication signal. For example, if it is determined that the time-domain start position of the uplink indication signal is in the first time slot according to the time-domain end position of the reference SSB and the time-domain offset, the start symbol of the uplink indication signal can be determined in the first time slot according to the time-domain start position indication information of the uplink indication signal; if the time-domain start position indication information of the uplink indication signal does not indicate the start symbol of the uplink indication signal, the start symbol of the uplink indication signal can be determined according to the start symbol predefined by the protocol. For example, the first symbol of the first time slot can be determined as the start symbol of the uplink indication signal.

[0207] (3) If the time-domain parameter of the uplink indication signal includes the number of time units occupied by the uplink indication signal, the terminal can determine the time-domain start position of the uplink indication signal as the first time unit after the time-domain end position of the SSB of the target cell, and then use the period of the SSB of the target cell as the period of the uplink indication signal. The time-domain position of the uplink indication signal is determined according to the time-domain start position of the uplink indication signal, the period of the uplink indication signal, and the number of time units occupied by the uplink indication signal.

[0208] For example, the position of the uplink indication signal in the time domain can be as Figure 6C shown.

[0209] In this manner, if the time-domain parameter of the uplink indication signal further includes the period of the uplink indication signal, the indicated period of the uplink indication signal can be used to determine the time-domain position of the uplink indication signal in the above manner.

[0210] (4) If the time-domain parameters of the uplink indication signal include the time-domain start position of the uplink indication signal, the number of time units occupied by the uplink indication signal, and the period of the uplink indication signal, the terminal can determine the time-domain position of the uplink indication signal according to the time-domain start position of the uplink indication signal, the number of time units occupied by the uplink indication signal, and the period of the uplink indication signal.

[0211] It should be noted that the above time-domain parameters of the uplink indication signal are only examples. If there are other unexemplified cases for the time-domain parameters of the uplink indication signal, the time-domain position of the uplink indication signal can be determined by referring to the manner in the above examples.

[0212] In Figure 4In the illustrated embodiment, the network device indicates first information to the terminal on the target cell, and the terminal communicates with the network device on the target cell based on the first information. The network device can send the first system information as needed, reducing the static power consumption of the network device.

[0213] Figure 7 It is a schematic flowchart of another communication method provided by an embodiment of the present application. As Figure 7 shown, taking the first cell as the anchor cell and the second cell as the non-anchor cell as an example, the method includes:

[0214] S701. The network device corresponding to the anchor cell determines first information, where the first information includes configuration information and / or indication information.

[0215] It should be noted that the execution process of S701 can refer to the execution process of S301, which will not be elaborated here. The only thing to note is that the second SSB and the first SSB are different SSBs, the first SSB is the SSB of the anchor cell, and the second SSB is the SSB of the non-anchor cell.

[0216] S702. The network device corresponding to the anchor cell sends second system information to the terminal on the anchor cell, where the second system information includes the first information.

[0217] The indication information can be carried by the WUS configuration of the non-anchor cell. Specifically, the WUS configuration of the non-anchor cell includes an activation or deactivation instruction. If it is deactivated, it means that the non-anchor cell is already sending the first system information.

[0218] S703. The terminal communicates with the network device corresponding to the non-anchor cell based on the first information.

[0219] It should be noted that the execution process of S703 can refer to the execution process of S303, which will not be elaborated here. The following details how to send an uplink indication signal to the corresponding network device on a non-anchor cell based on the configuration parameters of the uplink indication signal of a certain non-anchor cell.

[0220] The time-domain position of the uplink indication signal can be determined based on the time-domain parameters of the uplink indication signal, and the frequency-domain position of the uplink indication signal can be determined based on the frequency-domain position of the uplink indication signal. The uplink indication signal can be sent at the determined time-frequency position, and the format or sequence of the uplink indication signal can be the format or sequence indicated in the configuration parameters.

[0221] For the frequency-domain parameters of the uplink indication signal of any non-anchor cell, the following separately describes how to determine the frequency-domain position of the uplink indication signal based on different frequency-domain parameters of the uplink indication signal.

[0222] (1) If the frequency-domain parameters of the uplink indication signal include the frequency-domain bandwidth of the uplink indication signal, the terminal can determine the frequency-domain starting position of the SSB of the non-anchor cell by detecting the SSB of the non-anchor cell, determine the frequency-domain starting position of the uplink indication signal as the frequency-domain starting position of the SSB of the non-anchor cell, and determine the frequency-domain position of the uplink indication signal according to the frequency-domain starting position and frequency-domain bandwidth of the uplink indication signal.

[0223] In this method, if the frequency-domain parameters of the uplink indication signal further include the subcarrier spacing, the indicated subcarrier spacing can be used as the subcarrier spacing of the uplink indication signal; if the frequency-domain parameters of the uplink indication signal do not include the subcarrier spacing, the subcarrier spacing of the SSB of the non-anchor cell can be used as the subcarrier spacing of the uplink indication signal.

[0224] (2) If the frequency-domain parameters of the uplink indication signal include the frequency-domain bandwidth and frequency-domain offset of the uplink indication signal, the terminal can determine the frequency-domain starting position of the SSB of the non-anchor cell by detecting the SSB of the non-anchor cell, determine the frequency-domain starting position of the uplink indication signal according to the frequency-domain starting position and frequency-domain offset of the SSB of the non-anchor cell, and determine the frequency-domain position of the uplink indication signal according to the frequency-domain starting position and frequency-domain bandwidth of the uplink indication signal.

[0225] In this method, if the frequency-domain parameters of the uplink indication signal further include the subcarrier spacing, the indicated subcarrier spacing can be used as the subcarrier spacing of the uplink indication signal; if the frequency-domain parameters of the uplink indication signal do not include the subcarrier spacing, the subcarrier spacing of the SSB of the non-anchor cell can be used as the subcarrier spacing of the uplink indication signal.

[0226] (3) If the frequency-domain parameters of the uplink indication signal include the frequency-domain starting position and frequency-domain bandwidth of the uplink indication signal, the terminal can determine the frequency-domain position of the uplink indication signal according to the frequency-domain starting position and frequency-domain bandwidth of the uplink indication signal.

[0227] In this method, if the frequency-domain parameters of the uplink indication signal further include the subcarrier spacing, the indicated subcarrier spacing can be used as the subcarrier spacing of the uplink indication signal; if the frequency-domain parameters of the uplink indication signal do not include the subcarrier spacing, the subcarrier spacing of the SSB of the non-anchor cell can be used as the subcarrier spacing of the uplink indication signal.

[0228] It should be noted that the above frequency-domain parameters of the uplink indication signal are only examples. If there are other unexemplified situations for the frequency-domain parameters of the uplink indication signal, the frequency-domain position of the uplink indication signal can be determined with reference to the methods in the above examples.

[0229] For the time-domain parameters of the uplink indication signal of any non-anchor cell, the following separately describes how to determine the time-domain position of the uplink indication signal based on the time-domain parameters of different uplink indication signals.

[0230] (1) If the time-domain parameters of the uplink indication signal include the time-domain start position indication information of the uplink indication signal, the period indication information of the uplink indication signal, and the time-domain offset, the terminal can determine a reference SSB among the multiple SSBs of the non-anchor cell according to the time-domain start position indication information of the uplink indication signal, and then determine the time-domain start position of the uplink indication signal according to the time-domain end position of the reference SSB and the time-domain offset. Then, according to the period of the SSB of the non-anchor cell and the period indication information of the uplink indication signal, the period of the uplink indication signal can be determined. Finally, according to the time-domain start position of the uplink indication signal, the period of the uplink indication signal, and the number of time units occupied by the uplink indication signal predefined by the protocol, the time-domain position of the uplink indication signal is determined.

[0231] In this method, if the time-domain parameters of the uplink indication signal further include the number of time units occupied by the uplink indication signal, the indicated number of time units occupied by the uplink indication signal can be used to determine the time-domain position of the uplink indication signal according to the above method; if the granularity of the time-domain offset is a time slot, the time-domain start position indication information of the uplink indication signal can further indicate the start symbol of the uplink indication signal. For example, if it is determined that the time-domain start position of the uplink indication signal is in the first time slot according to the time-domain end position of the reference SSB and the time-domain offset, the start symbol of the uplink indication signal can be determined in the first time slot according to the time-domain start position indication information of the uplink indication signal; if the time-domain start position indication information of the uplink indication signal does not indicate the start symbol of the uplink indication signal, the start symbol of the uplink indication signal can be determined according to the start symbol predefined by the protocol. For example, the first symbol of the first time slot can be determined as the start symbol of the uplink indication signal; if the time-domain parameters of the uplink indication signal do not include the period indication information of the uplink indication signal, the period of the SSB of the target cell can be used as the period of the uplink indication signal to determine the time-domain position of the uplink indication signal according to the above method.

[0232] (2) If the time-domain parameters of the uplink indication signal include the time-domain offset of the uplink indication signal, the terminal can determine the time-domain start position of the uplink indication signal according to the time-domain end position of the SSB of the non-anchor cell and the offset, use the period of the SSB of the non-anchor cell as the period of the uplink indication signal, and then determine the time-domain position of the uplink indication signal according to the time-domain start position of the uplink indication signal, the period of the uplink indication signal, and the number of time units occupied by the uplink indication signal predefined by the protocol.

[0233] In this method, if the time-domain parameter of the uplink indication signal further includes the number of time units occupied by the uplink indication signal, the number of time units occupied by the indicated uplink indication signal can be used to determine the time-domain position of the uplink indication signal in the above manner; if the time-domain parameter of the uplink indication signal further includes the period of the uplink indication signal, the indicated period of the uplink indication signal can be used to determine the time-domain position of the uplink indication signal in the above manner; if the granularity of the time-domain offset is a time slot, the time-domain start position indication information of the uplink indication signal can further indicate the start symbol of the uplink indication signal. For example, if it is determined that the time-domain start position of the uplink indication signal is in the first time slot according to the time-domain end position of the reference SSB and the time-domain offset, the start symbol of the uplink indication signal can be determined in the first time slot according to the time-domain start position indication information of the uplink indication signal; if the time-domain start position indication information of the uplink indication signal does not indicate the start symbol of the uplink indication signal, the start symbol of the uplink indication signal can be determined according to the start symbol predefined by the protocol. For example, the first symbol of the first time slot can be determined as the start symbol of the uplink indication signal.

[0234] (3) If the time-domain parameter of the uplink indication signal includes the number of time units occupied by the uplink indication signal, the terminal can determine the time-domain start position of the uplink indication signal as the first time unit after the time-domain end position of the SSB of the non-anchor cell, and then use the period of the SSB of the non-anchor cell as the period of the uplink indication signal, and determine the time-domain position of the uplink indication signal according to the time-domain start position of the uplink indication signal, the period of the uplink indication signal, and the number of time units occupied by the uplink indication signal.

[0235] In this method, if the time-domain parameter of the uplink indication signal further includes the period of the uplink indication signal, the indicated period of the uplink indication signal can be used to determine the time-domain position of the uplink indication signal in the above manner.

[0236] (4) If the time-domain parameters of the uplink indication signal include the time-domain start position of the uplink indication signal, the number of time units occupied by the uplink indication signal, and the period of the uplink indication signal, the terminal can determine the time-domain position of the uplink indication signal according to the time-domain start position of the uplink indication signal, the number of time units occupied by the uplink indication signal, and the period of the uplink indication signal.

[0237] It should be noted that the above time-domain parameters of the uplink indication signal are only examples. If there are other unexemplified cases of the time-domain parameters of the uplink indication signal, the time-domain position of the uplink indication signal can be determined by referring to the methods in the above examples.

[0238] In Figure 7In the illustrated embodiment, the network device corresponding to the anchor cell indicates the first information to the terminal, and the terminal communicates with the network device corresponding to the non-anchor cell based on the first information. The network device corresponding to the non-anchor cell may send the first system information as needed, reducing the static power consumption of the network device corresponding to the non-anchor cell.

[0239] Figure 8 FIG. is a schematic structural diagram of a communication device provided by an embodiment of the present application. As Figure 8 shown, the communication device 10 may include:
