[0090] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0091] In this application, "and / or" is simply a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document indicates that the related objects are in an "or" relationship.

[0092] In this application, "at least one" means one or more, and "plurality" means two or more.

[0093] In this application, "at least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can mean: a, b, c, a and b, a and c, b and c, or a, b, and c, where each of a, b, and c can be an element itself or a set containing one or more elements.

[0094] The descriptions "first," "second," and so on, appearing in this application are for illustration and distinction purposes only. There is no order, nor does it represent a specific limit on the number of objects in the embodiments of this application, and it does not 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 between different SSBs, and does not indicate a difference in priority or importance between the two SSBs.

[0095] Throughout this application, the terms "exemplary," "in some embodiments," and "in other embodiments" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "exemplary" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of the word "exemplary" is intended to present concepts in a concrete manner.

[0096] To facilitate understanding, the concepts involved in the embodiments of the present application are first explained.

[0097] 1. Anchor cell

[0098] In a communication network, a cell that provides wide coverage is called an anchor cell, which may also be called an anchor carrier, a first-type carrier, a first-type cell, a primary carrier, or a primary cell (PCell).

[0099] 2. Non-anchor cell

[0100] In a communications network, a cell with limited coverage that provides high-speed data transmission services and can be shut down or put into a dormant state based on network load is called a non-anchor cell. When a cell is shut down or in a dormant state, it does not transmit system information. A non-anchor cell may also be referred to as a non-anchor carrier, a second-type carrier, a second-type cell, a secondary carrier, or a secondary cell (SCell).

[0101] 3. Random access process

[0102] The terminal can achieve synchronization and obtain the master system information block (MIB) by receiving the SSB, and the terminal determines the receiving resources and related configuration parameters of the system information block (SIB) 1 through the MIB.

[0103] The random access process is shown in Figure 1. The terminal first completes downlink synchronization by reading the MIB and SIB1. By reading SIB1, the terminal determines the resources used to send a preamble to the network device to indicate its intention to access the network. 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 RA-RNTI to monitor message 2 from the network device to descramble the message.

[0104] Message 2 may include a timing advance (TA), a temporary cell radio network temporary identity (TC-RNTI), power adjustment, and a resource indication for the terminal to send message 3. The terminal then sends its identity and a radio resource control (RRC) connection request (i.e., message 3) to the network device via the uplink scheduling indication in message 2. Finally, the network device may notify the terminal of the completion of the initial access process via message 4. Otherwise, the terminal may determine that the initial access process has failed.

[0105] Through the SIB1 message, the terminal can obtain the relevant configuration of the physical random access channel transmission occasion (RO), including the RO period size, 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.

[0106] For the network device, the network device needs to continuously detect the message 1 sent by the terminal on the configured RO resource to ensure that the message 1 sent by the terminal can be received in time.

[0107] 4. Network equipment

[0108] A network device is a device with wireless transceiver capabilities. It includes but is not limited to: evolutionary node B (eNB or eNodeB) in long term evolution (LTE), gNodeB or gNB or Transmission and Receiving Points (TRP) in new radio (NR), base stations in subsequent evolution systems, access nodes in wireless fidelity (WiFi) systems, wireless relay nodes, wireless backhaul nodes, etc. A 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. Multiple base stations can support networks of the same technology mentioned above, or they can support networks of different technologies mentioned above. A base station can include one or more co-located or non-co-located TRPs.

[0109] 5. Terminal

[0110] A terminal is a device with wireless transceiver capabilities. It can be deployed on land, indoors or outdoors, handheld, wearable, or in-vehicle; on water (such as ships); or in the air (such as on airplanes, balloons, and satellites). A terminal can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, virtual reality (VR) terminal equipment, augmented reality (AR) terminal, wireless terminal in industrial control, vehicle-mounted terminal, wireless terminal in self-driving, wireless terminal in remote medical care, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, wearable terminal, etc. The terminal involved in the embodiments of the present application may also be referred to as user equipment (UE), access terminal, vehicle-mounted terminal, industrial control terminal, UE unit, UE station, mobile station, mobile station, remote station, remote user equipment, mobile device, wireless communication device, UE agent or UE device, etc. The terminal may also be fixed or mobile.

[0111] For ease of understanding, the application scenarios applicable to the embodiments of the present application are described below in conjunction with Figure 2.

[0112] FIG2 is a schematic diagram of an application scenario provided by an embodiment of the present application. Referring to FIG2 , the application scenario includes network device 201 , network device 202 , network device 203 , network device 204 and terminal 205 .

[0113] The area covered by network device 201 is an 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 to be turned on or off as needed. Terminal 205 can establish a connection with any of network devices 201, 202, 203, and 204. Network devices 202, 203, and 204 can provide high-speed data transmission services to terminal 205 within their respective coverage areas.

[0114] 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 device 202, network device 203, or network device 204 is used only for data load balancing, it does not need to carry MIB and SIB1. However, if it needs to support paging, random access, and radio resource management (RRM) measurements, it still needs to carry MIB and SIB to support terminal time-frequency synchronization and RRM measurements.

[0115] FIG2 is merely a schematic diagram of an application scenario and does not constitute a limitation on the application scenario of the technical solution provided in this application.

[0116] In view of the technical problems raised in the background technology, an embodiment of the present application provides a communication method in which a network device corresponding to a first cell can configure configuration parameters of an uplink indication signal for a terminal, allowing the terminal to send an uplink indication signal to a network device corresponding to a second cell based on the configuration parameters, thereby triggering the network device corresponding to the second cell to send first system information on the second cell.

[0158] In a possible implementation, if the first cell and the second cell are different, the configuration information may further include an identifier of the second cell, and each identifier of the second cell corresponds to a configuration parameter of an uplink indication signal.

[0159] The indication information may be used to instruct the network device corresponding to the second cell whether to send the first system information on the second cell.

[0160] If the second cell and the first cell are different cells, the first information may include one or more indication information, where one indication information is used to indicate whether to send the first system information on a second cell.

[0161] In a possible implementation, if the first cell and the second cell are different, each indication information may further include an identifier of the second cell.

[0162] S302. The network device corresponding to the first cell sends first information to the terminal in the first cell.

[0163] Correspondingly, the terminal receives, in the first cell, the first information sent by the network device corresponding to the first cell.

[0164] If the first information includes configuration information and indication information, the network device corresponding to the first cell may send the configuration information and indication information to the terminal simultaneously on the first cell, or may send the configuration information and indication information to the terminal separately on the first cell.

[0165] S303. The terminal communicates with the network device corresponding to the second cell based on the first information.

[0166] If the first information includes configuration information, the terminal may send an uplink indication signal to a network device corresponding to the second cell on the second cell based on the configuration information.

[0167] 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, the terminal determines an access cell among the multiple second cells after receiving the configuration information. 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 meets the cell reselection criteria. 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.

[0168] If the first information includes indication information, and the indication information indicates that the network device corresponding to the second cell sends the first system information on the second cell, the terminal can receive the first system information sent by the network device corresponding to the second cell on the second cell based on the indication information.

[0169] In this case, if the second cell is different from the first cell, and the first information includes multiple indication information, and the multiple indication information indicates to send the first system information, the terminal can receive the first system information on multiple second cells.

[0170] 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 send the first system information on the second cell, the terminal can send an uplink indication signal to the network device corresponding to the second cell on the second cell based on the configuration information.

[0171] 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, if multiple indication information indicates not to send the first system information, the terminal determines an access cell among the multiple second cells after receiving the first information. 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 meets the cell reselection criteria. 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.

[0172] In the embodiment shown in Figure 3, the network device corresponding to the first cell determines first information, which includes configuration information and / or indication information. The configuration information includes configuration parameters for an uplink indication signal. The uplink indication signal is used to trigger the network device corresponding to the second cell to send first system information on the second cell. The indication information is used to indicate whether to send the first system information on the second cell. The first cell sends the first information to the terminal, 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 can send the first system information on demand, reducing the static energy consumption of the network device corresponding to the second cell.

[0173] Based on the embodiment shown in FIG3 , the communication method of the present application is described below in different scenarios.

[0174] FIG4 is a flow chart of another communication method provided by an embodiment of the present application. As shown in FIG4 , taking the first cell and the second cell as the same cell as an example, for ease of description, the first cell and the second cell are referred to as target cells, and the network device corresponding to the first cell and the network device corresponding to the second cell are referred to as network devices. The method includes:

[0175] S401: A network device determines first information, where the first information includes configuration information and / or instruction information.

[0176] It should be noted that the execution process of S401 can refer to the execution process of S301 and will not be repeated here. The only thing that needs to be noted is that the first SSB and the second SSB are the same SSB, and the first SSB and the second SSB are referred to as SSB below.

[0177] S402. The network device sends an SSB to the terminal in the target cell, where the SSB includes first information.

[0178] Correspondingly, the terminal receives the SSB sent by the network device in the target cell.

[0179] In a possible implementation, the first information is carried in the MIB of the SSB.

[0180] In a possible implementation, the indication information is carried in the SSB subcarrier offset field of the MIB.

[0181] In a possible implementation, the indication information is carried in a bit of information in the MIB, that is, a bit may be set in the MIB to indicate whether the network device sends the first system information on the target cell.

[0182] In one 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.

[0183] 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 the bit indicates that the network device does not send SIB1 on the target cell, the MIB includes configuration information; if the 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 receiving parameters of SIB1 through the MIB.

[0184] For another example, the value of the SSB subcarrier offset field in the SSB's MIB indicates whether the network device sends SIB1 on the target cell; when the SSB subcarrier offset field in the SSB's MIB 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 SSB subcarrier offset field in the SSB's MIB 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.

[0185] In one possible implementation, if the indication information instructs the network device not to send the first system information on the target cell, the remaining minimum system information (RMSI)-physical downlink control channel (PDCCH) configuration (config) field in the MIB is used to configure the configuration information; if the indication information instructs the network device to send 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.

[0186] 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 the 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 the bit indicates that the network device sends SIB1 on the target cell, the MIB does not include the configuration information. At this time, the RMSI-PDCCH configuration field can be used to configure the RMSI-PDCCH monitoring parameters.

[0187] For another example, the value of the SSB subcarrier offset field in the SSB's MIB indicates whether the network device sends SIB1 on the target cell; when the SSB subcarrier offset field in the SSB's MIB 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 RMSI-PDCCH configuration field in the MIB can be used to configure the configuration information; when the SSB subcarrier offset field in the SSB's MIB 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 the configuration information. At this time, the RMSI-PDCCH configuration field can be used to configure the RMSI-PDCCH monitoring parameters.

[0188] S403: The terminal communicates with the network device based on the first information.

[0189] It should be noted that the execution process of S403 can refer to the execution process of S303 and will not be repeated here. The following describes in detail how to send the uplink indication signal to the network device based on the configuration parameters of the uplink indication signal.

[0190] The time domain position of the uplink indication signal can be determined based on the time domain parameters of the uplink indication signal, 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.

[0191] The following describes how to determine the frequency domain position of the uplink indication signal based on different frequency domain parameters of the uplink indication signal.

[0192] (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 target cell by detecting the SSB sent by the network device on the target cell, and determine the frequency domain starting position of the SSB of the target cell as the frequency domain starting position of the uplink indication signal. The frequency domain position of the uplink indication signal can be determined according to the frequency domain starting position and the frequency domain bandwidth of the uplink indication signal.

[0193] For example, the frequency domain position of the uplink indication signal may be as shown in FIG5A .

[0194] In this way, if the frequency domain parameters of the uplink indication signal also include 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 subcarrier spacing, the subcarrier spacing of the SSB of the target cell can be used as the subcarrier spacing of the uplink indication signal.

[0195] (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 target cell by detecting the SSB sent by the network device on the target cell, and the frequency domain starting position of the uplink indication signal can be determined according to the frequency domain starting position and frequency domain offset of the SSB of the target cell, and the frequency domain position of the uplink indication signal can be determined according to the frequency domain starting position and frequency domain bandwidth of the uplink indication signal.

[0196] For example, the frequency domain position of the uplink indication signal may be as shown in FIG. 5B or FIG. 5C .

[0197] In this way, if the frequency domain parameters of the uplink indication signal also include 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 subcarrier spacing, the subcarrier spacing of the SSB of the target cell can be used as the subcarrier spacing of the uplink indication signal.

[0198] (3) If the frequency domain parameters of the uplink indication signal include the frequency domain starting position of the uplink indication signal and the frequency domain bandwidth of the uplink indication signal, the terminal may determine the frequency domain position of the uplink indication signal according to the frequency domain starting position and the frequency domain bandwidth of the uplink indication signal.

[0199] In this way, if the frequency domain parameters of the uplink indication signal also include 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 subcarrier spacing, the subcarrier spacing of the SSB of the target cell can be used as the subcarrier spacing of the uplink indication signal.

[0200] It should be noted that the above frequency domain parameters of the uplink indication signal are only examples. If there are other frequency domain parameters of the uplink indication signal that are not illustrated, the frequency domain position of the uplink indication signal can be determined by referring to the method in the above example.

[0201] The following describes how to determine the frequency domain position of the uplink indication signal based on different time domain parameters of the uplink indication signal.

[0202] (1) If the time domain parameters of the uplink indication signal include time domain starting position indication information of the uplink indication signal, period indication information of the uplink indication signal, and time domain offset, the terminal may determine a reference SSB among multiple SSBs based on the time domain starting position indication information of the uplink indication signal, and then determine the time domain starting position of the uplink indication signal based on the time domain end position and time domain offset of the reference SSB, and then determine the period of the uplink indication signal based on 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 based on the time domain starting 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.

[0203] For example, the position of the uplink indication signal in the time domain may be as shown in FIG6A . In FIG6A , the first detected SSB is used as the reference SSB, and 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.

[0204] In this manner, if the time domain parameters of the uplink indication signal also 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 in the above manner; if the granularity of the time domain offset is a time slot, the time domain starting position indication information of the uplink indication signal can also indicate the starting symbol of the uplink indication signal. For example, if the time domain starting position of the uplink indication signal is determined to be in the first time slot based on the time domain end position and the time domain offset of the reference SSB, the starting symbol of the uplink indication signal can be determined in the first time slot based on the time domain starting position indication information of the uplink indication signal; if the time domain starting position indication information of the uplink indication signal does not indicate the starting symbol of the uplink indication signal, the starting symbol of the uplink indication signal can be determined based on the starting symbol predefined by the protocol, for example, the first symbol of the first time slot can be determined as the starting symbol of the uplink indication signal; if the time domain parameters of the uplink indication signal do not include 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, and the time domain position of the uplink indication signal can be determined in the above manner.

[0205] (2) If the time domain parameters of the uplink indication signal include the time domain offset of the uplink indication signal, the terminal may determine the time domain starting position of the uplink indication signal based on the time domain ending position and the time domain offset of the SSB of the target cell, 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 based on the time domain starting 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.

[0206] For example, the position of the uplink indication signal in the time domain may be as shown in FIG6B .

[0207] In this manner, if the time domain parameters of the uplink indication signal also 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 in the above manner; if the time domain parameters of the uplink indication signal also include 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 time slot, the time domain starting position indication information of the uplink indication signal can also indicate the starting symbol of the uplink indication signal, for example, if the time domain starting position of the uplink indication signal is determined to be in the first time slot based on the time domain end position and the time domain offset of the reference SSB, the starting symbol of the uplink indication signal can be determined in the first time slot based on the time domain starting position indication information of the uplink indication signal; if the time domain starting position indication information of the uplink indication signal does not indicate the starting symbol of the uplink indication signal, the starting symbol of the uplink indication signal can be determined based on the starting symbol predefined by the protocol, for example, the first symbol of the first time slot can be determined as the starting symbol of the uplink indication signal.

[0208] (3) If the time domain parameters of the uplink indication signal include the number of time units occupied by the uplink indication signal, the terminal may determine the first time unit after the time domain end position of the SSB of the target cell as the time domain start position of the uplink indication signal, and then use the period of the SSB of the target 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.

[0209] For example, the position of the uplink indication signal in the time domain may be as shown in FIG6C .

[0210] In this manner, if the time domain parameters of the uplink indication signal also include the period of the uplink indication signal, the indicated period of the uplink indication signal may be used to determine the time domain position of the uplink indication signal in the manner described above.

[0211] (4) If the time domain parameters of the uplink indication signal include the time domain starting 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 may determine the time domain position of the uplink indication signal based on the time domain starting 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.

[0212] It should be noted that the above time domain parameters of the uplink indication signal are only examples. If there are other cases of the time domain parameters of the uplink indication signal that are not illustrated, the time domain position of the uplink indication signal can be determined by referring to the method in the above example.

[0213] In the embodiment shown in Figure 4, the network device indicates the first information to the terminal in the target cell, and the terminal communicates with the network device in the target cell based on the first information. The network device can send the first system information on demand, reducing the static energy consumption of the network device.

[0214] FIG7 is a flow chart of another communication method provided by an embodiment of the present application. As shown in FIG7 , taking the first cell as an anchor cell and the second cell as a non-anchor cell as an example, the method includes:

[0215] S701. A network device corresponding to an anchor cell determines first information, where the first information includes configuration information and / or indication information.

[0216] It should be noted that the execution process of S701 can refer to the execution process of S301 and will not be repeated 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.

[0217] 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.

[0218] The indication information may 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 indicates that the non-anchor cell is already sending the first system information.

[0219] S703: The terminal communicates with a network device corresponding to the non-anchor cell based on the first information.

[0220] It should be noted that the execution process of S703 can refer to the execution process of S303 and will not be repeated here. The following describes in detail how to send an uplink indication signal to a corresponding network device on a non-anchor cell based on the configuration parameters of the uplink indication signal of the non-anchor cell.

[0221] The time domain position of the uplink indication signal can be determined based on the time domain parameters of the uplink indication signal, 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.

[0222] For the frequency domain parameters of the uplink indication signal of any non-anchor cell, the following describes how to determine the frequency domain position of the uplink indication signal based on different frequency domain parameters of the uplink indication signal.

[0223] (1) If the frequency domain parameters of the uplink indication signal include the frequency domain bandwidth of the uplink indication signal, the terminal may 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 SSB of the non-anchor cell as the frequency domain starting position of the uplink indication signal, and determine the frequency domain position of the uplink indication signal according to the frequency domain starting position and the frequency domain bandwidth of the uplink indication signal.

[0224] In this way, if the frequency domain parameters of the uplink indication signal also include 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 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.

[0225] (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 may 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 based on 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 based on the frequency domain starting position and frequency domain bandwidth of the uplink indication signal.

[0226] In this way, if the frequency domain parameters of the uplink indication signal also include 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 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.

[0227] (3) If the frequency domain parameters of the uplink indication signal include the frequency domain starting position of the uplink indication signal and the frequency domain bandwidth of the uplink indication signal, the terminal may determine the frequency domain position of the uplink indication signal according to the frequency domain starting position and the frequency domain bandwidth of the uplink indication signal.

[0228] In this way, if the frequency domain parameters of the uplink indication signal also include 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 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.

[0229] It should be noted that the above frequency domain parameters of the uplink indication signal are only examples. If there are other frequency domain parameters of the uplink indication signal that are not illustrated, the frequency domain position of the uplink indication signal can be determined by referring to the method in the above example.

[0230] With respect to the time domain parameters of the uplink indication signal of any non-anchor cell, the following describes how to determine the time domain position of the uplink indication signal based on different time domain parameters of the uplink indication signal.

[0231] (1) If the time domain parameters of the uplink indication signal include time domain starting position indication information of the uplink indication signal, period indication information of the uplink indication signal, and time domain offset, the terminal may determine a reference SSB from multiple SSBs of the non-anchor cell based on the time domain starting position indication information of the uplink indication signal, and then determine the time domain starting position of the uplink indication signal based on the time domain end position and the time domain offset of the reference SSB, and then determine the period of the uplink indication signal based on the period of the SSB of the non-anchor cell and the period indication information of the uplink indication signal, and finally determine the time domain position of the uplink indication signal based on the time domain starting 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.

[0232] In this manner, if the time domain parameters of the uplink indication signal also 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 in the above manner; if the granularity of the time domain offset is a time slot, the time domain starting position indication information of the uplink indication signal can also indicate the starting symbol of the uplink indication signal. For example, if the time domain starting position of the uplink indication signal is determined to be in the first time slot based on the time domain end position and the time domain offset of the reference SSB, the starting symbol of the uplink indication signal can be determined in the first time slot based on the time domain starting position indication information of the uplink indication signal; if the time domain starting position indication information of the uplink indication signal does not indicate the starting symbol of the uplink indication signal, the starting symbol of the uplink indication signal can be determined based on the starting symbol predefined by the protocol, for example, the first symbol of the first time slot can be determined as the starting symbol of the uplink indication signal; if the time domain parameters of the uplink indication signal do not include 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, and the time domain position of the uplink indication signal can be determined in the above manner.

[0233] (2) If the time domain parameters of the uplink indication signal include the time domain offset of the uplink indication signal, the terminal may determine the time domain starting position of the uplink indication signal based on the time domain ending position and offset of the SSB of the non-anchor cell, 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 based on the time domain starting 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.

[0234] In this manner, if the time domain parameters of the uplink indication signal also 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 in the above manner; if the time domain parameters of the uplink indication signal also include 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 time slot, the time domain starting position indication information of the uplink indication signal can also indicate the starting symbol of the uplink indication signal, for example, if the time domain starting position of the uplink indication signal is determined to be in the first time slot based on the time domain end position and the time domain offset of the reference SSB, the starting symbol of the uplink indication signal can be determined in the first time slot based on the time domain starting position indication information of the uplink indication signal; if the time domain starting position indication information of the uplink indication signal does not indicate the starting symbol of the uplink indication signal, the starting symbol of the uplink indication signal can be determined based on the starting symbol predefined by the protocol, for example, the first symbol of the first time slot can be determined as the starting symbol of the uplink indication signal.

[0235] (3) If the time domain parameters of the uplink indication signal include the number of time units occupied by the uplink indication signal, the terminal may determine the first time unit after the time domain end position of the SSB of the non-anchor cell as the time domain start position of the uplink indication signal, 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 based on 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.

[0236] In this manner, if the time domain parameters of the uplink indication signal also include the period of the uplink indication signal, the indicated period of the uplink indication signal may be used to determine the time domain position of the uplink indication signal in the manner described above.

[0237] (4) If the time domain parameters of the uplink indication signal include the time domain starting 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 may determine the time domain position of the uplink indication signal based on the time domain starting 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.

[0238] It should be noted that the above time domain parameters of the uplink indication signal are only examples. If there are other cases of the time domain parameters of the uplink indication signal that are not illustrated, the time domain position of the uplink indication signal can be determined by referring to the method in the above example.

[0239] In the embodiment shown in Figure 7, 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 can send the first system information on demand, reducing the static energy consumption of the network device corresponding to the non-anchor cell.

[0241] A receiving module 11 is configured to receive first information on a first cell, the first information including configuration information and / or indication information, the configuration information including configuration parameters of an uplink indication signal, the uplink indication signal being used to trigger a network device to send first system information on a second cell; the indication information being used to instruct the network device whether to send the first system information on the second cell;

[0242] The communication module 12 is configured to communicate with the network device based on the first information.

[0243] In a possible implementation manner, the first cell and the second cell are the same cell, and the receiving module 11 is specifically configured to:

[0245] In a possible implementation, the first information is carried in a master system information block MIB in the first SSB.
