Description

Method and communication apparatus for information transmission

[0001] The present application claims priority from the Chinese patent application No. 202411398404.0 filed on September 30, 2024, and entitled "Method and communication apparatus for information transmission", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication, and more particularly, to a method and communication apparatus for information transmission. BACKGROUND

[0003] A synchronization signal block (SSB) can also be referred to as a synchronization signal (SS) or a physical broadcast channel block (PBCH block). In the current communication network, a terminal mainly performs cell search based on searching for an SSB, and successful reception of the SSB by the terminal is a prerequisite for accessing the cell. Therefore, the terminal needs to correctly receive the SSB. For the SSB of a network energy saving (NES) cell, multiple transmission periods of the SSB can be configured for the NES cell, and the transmission periods of the SSB in the NES cell can be different in different time periods.

[0004] In the current communication system, a network device periodically transmits some common signals to facilitate the terminal to identify the network and thus access the network. The network device frequently and periodically transmits the common signals, which results in a large overhead of the network device. Based on this, the 3rd generation partnership project (3GPP) started to study network energy saving (NES) in Release 19, and proposed to introduce adaptive processing of the common signals for some cells to achieve energy saving. Taking the SSB as an example, a terminal can detect the SSB based on SSB-measurement timing configuration (SMTC). When the terminal detects the SSB of a neighboring cell, if the neighboring cell is a cell that supports adaptive processing of the common signals to achieve energy saving, the terminal may appear abnormal detection in the process of detecting the SSB of the neighboring cell using the configured SMTC, which cannot guarantee the accuracy of SSB detection and can cause the mobility handover performance of the terminal to decrease. SUMMARY

[0005] The application provides a method and a communication device for information transmission, which realize corresponding SMTC (SMTC-NES) configuration for NES cells, improve SSB detection accuracy of a terminal for NES cells, avoid SSB detection abnormalities, and improve mobility management performance.

[0006] In a first aspect, a method for information transmission is provided. An execution subject of the method can be a terminal. The terminal can be a terminal device, a component (chip, chip system, or processor) supporting the terminal device to implement the method, or a logic module or software capable of implementing all or part of the terminal device functions. The method comprises: receiving first configuration information, the first configuration information comprising: measurement configuration corresponding to M NES cells, M being an integer greater than or equal to 1; and detecting SSBs of N NES cells according to the first configuration information, N being less than or equal to M, and the M NES cells comprising the N NES cells.

[0007] In the method for information transmission provided in the first aspect, the terminal can receive measurement configuration corresponding to M NES cells sent by a network device, for example, SMTC corresponding to multiple NES cells, and then detect SSBs of one or more NES cells according to the first measurement configuration information. Since the first configuration information comprises SMTC corresponding to multiple NES cells, the corresponding SMTC is configured for the NES cells, the SSB detection accuracy of the terminal for the NES cells is improved, SSB detection abnormalities are avoided, and the mobility management performance is improved.

[0008] In a possible implementation manner, the multiple NES cells can comprise same-frequency cells and different-frequency cells.

[0009] In a possible implementation manner, the multiple NES cells can all be same-frequency cells or different-frequency cells.

[0010] In a possible implementation manner, the M NES cells can all be neighboring cells of a cell where the terminal device is located.

[0011] In a possible implementation manner of the first aspect, the method further comprises: receiving second configuration information, the second configuration information comprising: measurement configuration corresponding to at least one non-NES cell. In this implementation manner, the terminal can receive measurement configuration corresponding to at least one non-NES cell sent by the network device, for example, SMTC corresponding to multiple non-NES cells, and then detect SSBs of one or more non-NES cells according to the second measurement configuration information. The corresponding SMTC is configured for the non-NES cells, the SSB detection accuracy of the terminal for the non-NES cells is improved, SSB detection abnormalities are avoided, and the mobility management performance is improved.

[0012] In a possible implementation, the plurality of non-NES cells can include intra-frequency cells and inter-frequency cells.

[0013] In a possible implementation, the plurality of non-NES cells can all be intra-frequency cells or inter-frequency cells.

[0014] In a possible implementation, the at least one non-NES cell can all be a neighbor cell of a cell in which the terminal device is located.

[0015] In a possible implementation of the first aspect, the first configuration information includes: a first SMTC and identifiers of the M NES cells respectively corresponding to the first SMTC. In this implementation, the M NES cells all correspond to the first SMTC. When the terminal detects an SSB of any one of the M NES cells, the terminal can use the period indicated by the first SMTC to perform the detection. On the one hand, the first configuration information has a small overhead, and the communication resources used to transmit the first configuration information can be reduced. On the other hand, it can be ensured that the terminal can detect the SSB of any one of the M NES cells using the first SMTC, and the accuracy of the terminal detecting the SSB of the NES cell can be improved, and detection abnormalities can be avoided.

[0016] For example, the first configuration information can include: a first SMTC and a cell identifier list (PCl List), and the cell identifier list includes identifiers of a plurality of NES cells. The cells in the cell identifier list all correspond to the first SMTC.

[0017] In a possible implementation of the first aspect, the first SMTC indicates a first period, and the first period is a maximum value in maximum transmission periods of SSBs respectively corresponding to the M NES cells. Alternatively, the first SMTC indicates a first period, and the first period is a maximum value in periods respectively indicated by SMTCs of the M NES cells. In this implementation, it can be ensured that the terminal can detect the SSB of any one of the M NES cells using the first SMTC, and the accuracy of the terminal detecting the SSB of the NES cell can be improved, and detection abnormalities can be avoided.

[0018] In a possible implementation of the first aspect, the first configuration information includes: identifiers of M SMTCs and M NES cells respectively corresponding to the M SMTCs, one SMTC corresponding to one NES cell. In this implementation, one SMTC corresponds to one NES cell, and the SMTC and the NES cell are in a one-to-one relationship. Different NES cells correspond to different SMTCs, which can improve the flexibility of the configuration of the NES corresponding SMTC. The terminal can detect the SSB of the NES cell according to the SMTC corresponding to the NES cell to be measured. Since a certain SMTC matches one NES cell instead of all NES cells, the period indicated by the SMTC can be relatively small, which can improve the accuracy of the terminal detecting the SSB of the NES cell corresponding to the SMTC, speed up the mobility measurement of the terminal, and improve the mobility management performance.

[0019] In a possible implementation of the first aspect, the first configuration information includes: identifiers of S SMTCs and M NES cells respectively corresponding to the S SMTCs and the M NES cells, S being less than M, and one SMTC corresponding to one or more NES cells. In this implementation, multiple different SMTCs and identifiers of M NES cells are included, each SMTC corresponding to at least one identifier of an NES cell, and the number of NES cells corresponding to each SMTC can be the same or different. The flexibility of the configuration of the NES corresponding SMTC can be improved, and the terminal can detect the SSB of the NES cell according to the SMTC corresponding to the NES cell to be measured.

[0020] For example, the S SMTCs include a second SMTC, and the second SMTC indicates a second period, the second period being: a maximum value in periods indicated by SMTCs corresponding to at least one NES cell corresponding to the second SMTC, or a maximum value in maximum transmission periods of SSBs corresponding to at least one NES cell corresponding to the second SMTC. In this implementation, since a certain SMTC matches part of the NES cells instead of all NES cells, the maximum value in the maximum transmission periods of the SSBs corresponding to the NES cells, the period indicated by the SMTC can be relatively small, which can improve the accuracy of the terminal detecting the SSB of the NES cell corresponding to the SMTC to a certain extent, speed up the mobility measurement of the terminal, and improve the mobility management performance.

[0021] In a possible implementation of the first aspect, according to the first configuration information, the SSBs of the N NES cells are detected, including: determining SMTCs corresponding to the N NES cells respectively; determining measurement periods of the N NES cells respectively according to the SMTCs indicated by the N NES cells respectively; and detecting SSBs of the N NES cells respectively according to the measurement periods of the N NES cells respectively. In this implementation, the terminal can detect the SSBs of the NES cells according to the SMTCs corresponding to the NES cells to be measured. The flexibility and accuracy of the terminal in detecting the SSBs of the NES cells can be improved.

[0022] In a possible implementation of the first aspect, the first configuration information can be carried in a measurement object (MO).

[0023] For example, the first configuration information and the second configuration information can be carried in the same signaling, or the first configuration information and the second configuration information can be carried in different signaling respectively.

[0024] In the second aspect, a method for information transmission is provided. An execution subject of the method can be a network side device, which can be a first network device, a component (chip, chip system, or processor) supporting the first network device to implement the method, or a logic node, logic module, or software, etc. that can implement all or part of the functions of the first network device. The method includes: receiving first information, the first information being used to indicate transmission periods of SSBs of NES cells corresponding to at least one second network device and / or SMTC information of the NES cells; determining first configuration information according to the first information, the first configuration information including measurement configurations of M NES cells, where M is an integer greater than or equal to 1; and sending the first configuration information.

[0025] In the method for information transmission provided in the second aspect, the first network device can obtain the transmission periods of the SSBs of the NES cells corresponding to other network devices (at least one second network device) and / or the SMTC information of the cells, determine measurement configurations of multiple NES cells according to the transmission periods of the SSBs of the NES cells corresponding to the other network devices and / or the SMTC information, etc., the measurement configurations of the multiple NES cells including SMTCs of the multiple NES cells, different NES cells can correspond to the same or different SMTCs, and the measurement configurations of the multiple NES cells determined are sent to terminals in cells served by the first network device. The method can configure the SMTCs corresponding to the NES cells, improve the accuracy of the terminals in detecting the SSBs of the NES cells, avoid SSB detection abnormalities, and improve the performance of mobility management.

[0026] In a possible implementation of the second aspect, the first information includes: first indication information and SMTC of the first cell corresponding to the second network device, the first indication information being used to indicate that the first cell is an NES cell, and the SMTC of the first cell indicating a period that is: a maximum transmission period of an SSB corresponding to the first cell, or a current transmission period of the SSB corresponding to the first cell. In this implementation, on one hand, the first network device can be explicitly informed that the second NES cell is an NES cell, and the accuracy of the second network device in determining that the second NES cell is an NES cell is improved. On the other hand, if the period indicated by the SMTC of the second NES cell is the maximum transmission period of the SSB corresponding to the second NES cell, in this case, a terminal (for example, a terminal in another cell) can detect the SSB of the second NES cell according to the period indicated by the SMTC of the second NES cell, regardless of the actual transmission period used by the SSB in the second NES cell, and the accuracy of the terminal in detecting the SSB of the second NES cell is improved. If the period indicated by the SMTC of the second NES cell is the current transmission period of the SSB corresponding to the second NES cell (that is, the actual transmission period of the SSB in the second NES cell), in this case, if the actual transmission period used by the SSB in the second NES cell does not change or becomes smaller, the terminal in another cell can also detect the SSB of the second NES cell according to the period indicated by the SMTC of the second NES cell, and the accuracy of the terminal in detecting the SSB of the second NES cell is improved to a certain extent. Moreover, because the period indicated by the SMTC of the second NES cell is shorter, the mobility measurement of the terminal can be accelerated, and the mobility management performance is improved. The accuracy of the first network device in determining the first configuration information is improved.

[0027] In a possible implementation of the second aspect, the first information includes: SMTC of the first NES cell corresponding to the second network device, and the SMTC of the first cell indicating a period that is: a maximum transmission period of an SSB corresponding to the first NES cell. In this implementation, a terminal (for example, a terminal in another cell) can detect the SSB of the second NES cell according to the period indicated by the SMTC of the second NES cell, regardless of the actual transmission period used by the SSB in the second NES cell, and the accuracy of the terminal in detecting the SSB of the second NES cell is improved. The accuracy of the first network device in determining the first configuration information is improved.

[0028] In a possible implementation of the second aspect, the first information includes a plurality of different transmission periods corresponding to SSBs of the first NES cell corresponding to the second network device. In this implementation, the accuracy of the determination of the first configuration information for the SMTC of the first NES cell by the first network device can be improved.

[0029] In a possible implementation of the second aspect, the first information includes transmission periods and / or SMTC information of SSBs corresponding to the M NES cells, and the first configuration information is determined according to the first information as follows: a maximum value in maximum transmission periods of the SSBs corresponding to the M NES cells is determined as a first period indicated by a first SMTC indication in the first configuration information, or a maximum value in periods indicated by SMTC indications of the M NES cells is determined as the first period indicated by the first SMTC indication in the first configuration information; wherein the first configuration information includes the first SMTC and identifiers of the M NES cells, and the M NES cells all correspond to the first SMTC. In this implementation, on one hand, the overhead of the first configuration information is small, and the communication resources used for transmitting the first configuration information can be reduced. On the other hand, it can be ensured that the terminal can detect SSBs of any one of the M NES cells using the first SMTC, the accuracy of the detection of the SSBs of the NES cells by the terminal is improved, and detection anomalies can be avoided.

[0030] In a possible implementation of the second aspect, the first information includes transmission periods of SSBs corresponding to the M NES cells respectively and / or SMTC information, and the determining the first configuration information according to the first information includes: dividing the M NES cells into S groups, each group including an identification of at least one NES cell, and S being less than M; determining a maximum value in maximum transmission periods of SSBs corresponding to NES cells included in a first group of the S groups as a period indicated by SMTC corresponding to the first group in the first configuration information, or determining a maximum value in periods indicated by SMTC corresponding to NES cells included in the first group of the S groups as the period indicated by SMTC corresponding to the first group in the first configuration information, each group corresponding to one SMTC, and the first group being any one of the S groups; and the first configuration information includes S SMTCs and identifications of the M NES cells respectively, and one SMTC corresponding to one group of NES cells. In this implementation, since a certain SMTC matches part of NES cells instead of all NES cells, a maximum value in maximum transmission periods of SSBs corresponding to the NES cells, the period indicated by the SMTC can be relatively small, which can improve the accuracy of the terminal in detecting SSBs of NES cells corresponding to the SMTC, accelerate the mobility measurement of the terminal, and improve the mobility management performance.

[0031] In a possible implementation of the second aspect, the method further includes: sending second configuration information, and the second configuration information includes measurement configuration corresponding to at least one non-NES cell. In this implementation, the terminal can detect SSBs of non-NES cells according to SMTC corresponding to the non-NES cells as needed, which can improve the flexibility and accuracy of the terminal in detecting SSBs of non-NES cells.

[0032] For example, the first information is carried in SMTC signaling.

[0062] Firstly, NES cell involved in the present application is explained.

[0063] In current communication system, network device periodically sends some common signals, which facilitates terminal to identify network and thus access. Network device frequently and periodically sends common signals, which results in large overhead of network device. Based on this, 3GPP Release 19 starts to study NES, and considers to adaptively process common signals to realize energy saving. Taking SSB as an example, for SSB sending (also can be called transmitting), the following contents are proposed: supporting adaptive change of SSB transmission period, transmission time domain location (SSB pattern) and other parameters. In the present application, the cell supporting adaptive processing of common signals to realize energy saving is called NES cell. Still taking SSB as an example, for example, one NES cell can configure multiple SSB sending periods, and in different time periods, SSB sending period in NES cell can be different. For another example, one NES cell can support non-periodic SSB sending. For another example, one NES cell can support both non-periodic SSB sending and periodic SSB sending. For another example, one NES cell can support both non-periodic SSB sending and periodic SSB sending under multiple periods. For another example, one NES cell can support on demand SSB (od-SSB) sending or support SSB periodicity adaptation.

[0064] Corresponding to the NES cell is a non-NES cell, for example, the non-NES cell does not support adaptive processing of common signals. The non-NES cell can also be referred to as a legacy cell or a normal cell. For example, the SSB transmission period of the non-NES cell can remain unchanged for a long time. For example, the non-NES cell does not support aperiodic transmission of SSBs.

[0065] In some possible scenarios, the SSB is periodically transmitted and the period can be configured, but the terminal does not need to detect the SSB according to the SSB period. In order to avoid unnecessary measurement of the terminal and reduce the power consumption of the terminal, the protocol defines the SSB-based measurement timing configuration (SMTC). The network device can send the SMTC to the terminal, and the SMTC indicates the period and detection occasion of the terminal detecting or measuring the SSB. The terminal can detect the SSB according to the SMTC. For example, the SMTC can indicate a measurement window of the SSB, and the window indicated by the SMTC is referred to as an SMTC window. The terminal only needs to perform SSB measurement in the SMTC window, and does not need to perform SSB measurement outside the SMTC window.

[0066] For example, the configuration parameters of the SMTC window (the window indicated by the SMTC) can include SMTC timing and SMTC duration, wherein the SMTC timing includes period and offset information of the SMTC window. Alternatively, it can also be said that the configuration parameters of the SMTC window (the measurement time window configuration indicated by the SMTC) include the period of the SMTC window, the offset of the SMTC window, and the SMTC window duration. For example, the period of the SMTC window can be 5, 10, 20, 40, 80, or 160 ms, and the period of the SSB detected by the terminal is 5, 10, 20, 40, 80, or 160 ms. That is, the terminal can determine the period of detecting the SSB according to the period indicated in the SMTC.

[0067] It should be understood that, in order to improve the efficiency of the terminal detecting the SSB, the period of the SMTC window can be greater than or equal to the actual transmission period of the SSB. For example, the transmission period of the SSB includes 5, 10, 20, 40, 80, or 160 ms, if the actual transmission period of the SSB is 20 ms, the period of the SMTC window can be 20 ms or greater than 20 ms. If the actual transmission period of the SSB is 80 ms, the period of the SMTC window can be 80 ms or greater than 80 ms.

[0068] Optionally, in this application, the SMTC indicated period can also be referred to as: SMTC indicated time window period, SMTC window period, or SMTC indicated measurement time window period. If not specifically stated, the four have the same meaning and can be replaced by each other. In the following description, the expression "SMTC indicated period" will be taken as an example for description.

[0069] It can be understood that the larger the SMTC indicated period, the greater the latency of the terminal detecting the SSB, which will cause the terminal's mobility switching performance to decline, for example, it will increase the terminal's switching time to the cell. The smaller the SMTC indicated period, the smaller the latency of the terminal detecting the SSB, which will speed up the terminal's mobility measurement and improve the mobility management performance.

[0070] In the process of detecting the SSB of different cells by the terminal, it can be divided into intra-frequency measurement and inter-frequency measurement. Among them, the intra-frequency measurement can be understood as: the terminal respectively detects the SSB of different cells on the same center frequency point, and the center frequency points (or also can be referred to as carrier frequency points) corresponding to these different cells are the same. The inter-frequency measurement can be understood as: the terminal respectively detects the SSB of different cells on different center frequency points, and the center frequency points corresponding to these different cells are not the same.

[0071] For intra-frequency measurement, the existing protocol supports 2 SMTC configurations (SMTC1 and SMTC2), where SMTC1 is applicable for SSB detection of all cells, and SMTC2 is applicable for SSB detection of part of cells or specific cells. Wherein, SMTC2 corresponds to a physical cell identifier list (PCI List) which indicates the cells to which SMTC2 is applicable. However, the protocol limits that the periodicity in SMTC2 can only be set to a value strictly shorter than the periodicity indicated by periodicityAndOffset in smtc1, and the offset of SMTC2 and SMTC1 is the same, and does not support separate configuration of offset, the main purpose of which is to accelerate the mobility measurement of the corresponding cell configured with SMTC2 to improve the performance of mobility management. Wherein, the offset of SMTC can be understood as the offset of SMTC window. For example, the offset of SMTC window can be the time of the offset (or lag) of SMTC window relative to a certain reference point. For example, the reference point can be a certain point of a radio frame. The offset of SMTC window can ensure that the terminal can start measuring SSB at the correct time. For example, the boundary of SMTC window can be aligned with the subframe boundary of the cell configured for measurement, and the offset of SMTC window can be the time of the offset of SMTC window relative to the subframe boundary.

[0072] However, in the current protocol, for SMTC1 and SMTC2, the protocol does not distinguish whether the cells corresponding to SMTC1 or SMTC2 are of which type, or in other words, the current protocol does not distinguish whether the cells corresponding to SMTC1 or SMTC2 are NES cells or non-NES cells. In other words, the cells corresponding to SMTC1 can include NES cells and non-NES cells, and the cells corresponding to SMTC2 can also include NES cells and non-NES cells. That is, the terminal uses the same SMTC when detecting SSB using SMTC (such as SMTC1 or SMTC2) for NES cells and non-NES cells.

[0073] For intra-NES cell measurement, for example, the terminal needs to detect the SSB of the first NES cell and the second NES cell at the same center frequency point, wherein the first NES cell is the serving cell currently serving the terminal, and the second NES cell can be a neighbor cell of the first NES cell. For the first NES cell, after the SSB transmission period of the first NES cell changes, the terminal can update the SMTC (for example, SMTC1 is updated to SMTC2, or SMTC2 is updated to SMTC1) accordingly to ensure accurate detection of the SSB. For example, the network device corresponding to the first NES cell can notify the terminal to update the SMTC used. However, after the SSB transmission period of the second NES cell changes, for example, as shown in FIG. 1, the SSB transmission period of the second NES cell changes from SSB period 1 to SSB period 2, and the value of SSB period 2 is greater than the value of SSB period 1, that is, the current SSB transmission period is SSB period 2. In this case, the terminal still uses the SMTC sent by the network device corresponding to the first NES cell to detect the SSB of the second NES cell. If SSB period 2 is greater than the period indicated by SMTC1, the terminal will have detection abnormality (also referred to as measurement abnormality) no matter whether SMTC1 or SMTC2 is used to detect the SSB of the second NES cell, that is, there is no SSB transmission at the corresponding detection position, and the SSB cannot be detected at the detection position. As shown in FIG. 1, the terminal uses SMTC1 to detect the SSB of the second NES cell.

[0074] For inter-NES cell measurement, the existing protocol only supports one SMTC configuration (SMTC1), for example, the terminal needs to detect the SSB of the first NES cell and the second cell at different center frequency points. The second cell can be an NES cell or a non-NES cell. The second cell is the serving cell currently serving the terminal, and the first NES cell can be a neighbor cell of the second cell. Since the network device corresponding to the second cell can only configure one SMTC (SMTC1) for the terminal, after the SSB period of the first NES cell changes, for example, as shown in FIG. 2, the SSB transmission period of the first NES cell changes from SSB period 1 to SSB period 2, and the value of SSB period 2 is greater than the value of SSB period 1, that is, the current SSB transmission period is SSB period 2. In this case, the terminal still uses the configured SMTC1 to measure the SSB of the first NES cell, and measurement abnormality can occur: that is, there is no SSB transmission at the corresponding detection position, and the SSB cannot be detected at the detection position.

[0075] In summary, for intra-frequency measurement, the SMTC1 or SMTC2 corresponding to the cell defined in the current protocol does not distinguish between NES cells and non-NES cells. In the case where the SMTC1 or SMTC2 corresponding cell includes NES cells, the SSB period of the NES cell cannot be applied to the scenario where the SSB period of the NES cell is increased, and the configuration parameters of SMTC2 are limited. For inter-frequency measurement, the existing mechanism cannot configure additional SMTC to ensure the measurement accuracy of the SSB of the NES cell. Both the intra-frequency measurement and the inter-frequency measurement of the NES cell will cause the terminal to detect abnormally when detecting the SSB, cannot guarantee the accuracy of the SSB detection of the NES cell, and will cause the mobility switching performance of the terminal to decline. If the period indicated in the SMTC1 is configured as the maximum transmission period of the SSB of all cells, since the SMTC1 is applied to the cells without distinguishing between NES cells and non-NES cells, the period indicated in the SMTC will be large, and the terminal will detect the SSB of all cells using the SMTC1. The larger the delay of the terminal in detecting the SSB, the more the mobility switching performance of the terminal will decline.

[0076] In view of this, the present application provides a method and a communication device for information transmission. The network devices can interact with each other the transmission period and / or SMTC and the like information of the SSB of the (corresponding) NES cell served by each network device. The network device can determine the measurement configuration corresponding to a plurality of NES cells according to the transmission period and / or SMTC and the like information of the SSB of the NES cell corresponding to other network devices, for example, including the SMTC corresponding to a plurality of NES cells. The plurality of NES cells can correspond to the same or different SMTC. The network device sends the determined measurement configuration corresponding to a plurality of NES cells to the terminal in the cell served by the network device. The terminal can detect the SSB of the cell to which the terminal belongs and the SSB of other NES cells according to the SMTC information. The corresponding SMTC for the NES cell is configured, the SSB detection accuracy of the terminal for the NES cell is improved, the SSB detection abnormality is avoided, and the mobility management performance is improved.

[0077] To facilitate understanding of the embodiments of the present application, first, a communication system suitable for the embodiments of the present application is briefly introduced.

[0078] For example, FIG. 3 is a schematic diagram of another example of a communication system 30 that can be used in embodiments of the present application. As shown in FIG. 3, the communication system 30 includes a radio access network (RAN) 300, a core network (CN) 330, and the Internet 340. The RAN 300 includes at least one RAN node (e.g., nodes 310a and 310b, collectively 310, in FIG. 3) and at least one terminal (e.g., 320a-320j, collectively 320, in FIG. 3). Other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in FIG. 3), can also be included in the RAN 300. For example, a “node” can also be referred to as a “network element,” e.g., nodes 310a and 310b can also be referred to as network elements 310a and 310b, and nodes 320a-320j can also be referred to as network elements 320a-320j.

[0079] The terminals 320 are connected to the RAN nodes 310 by wireless or wired means. Different terminals are connected to each other by wireless or wired means. The RAN nodes 310 are connected to the core network 330 by wireless or wired means. The core network devices in the core network 330 and the RAN nodes 310 in the RAN 300 can be different physical devices, or they can be integrated into the same physical device, or they can be a physical device that integrates some of the functions of the core network devices and some of the functions of the RAN nodes 310.

[0080] In the example shown in FIG. 3, the cells served by the RAN nodes 310 can be NES cells, e.g., the cells corresponding to nodes 310a and 310b can be NES cells, and nodes 310a and 310b can transmit SSBs using different periodicities in different time periods, respectively.

[0081] The RAN 300 can be a 3rd Generation Partnership Project (3GPP) -related cellular system, such as a Long Term Evolution (LTE) system, an LTE Frequency Division Duplex (FDD) system, an LTE Time Division Duplex (TDD), a 3G, a 5G mobile communication system (including a standalone and non-standalone mode), a New Radio (NR), a future communication network, a cloud radio access network (CRAN), or also an open radio access network (O-RAN or ORAN) system, or also a communication system that combines two or more of the above systems. The embodiments of the present application are not limited here.

[0082] The RAN node 310, which can also be referred to as an access network device, a radio access network device, a network device, a RAN entity, or an access node, etc., constitutes part of the communication system, and is configured to help terminals to implement wireless access. The plurality of RAN nodes 310 in the communication system 300 can be nodes of the same type or nodes of different types.

[0083] In some scenarios, the roles of the RAN node 310 and the terminal 320 are relative, for example, the network element 320i in FIG. 3 can be a helicopter or a drone, which can be configured as a mobile base station. For those terminals 320j that access the RAN 300 through the network element 320i, the network element 320i is a base station; but for the base station 310a, the network element 320i is a terminal. That is, the base station 310a and the terminal 320i communicate with each other through a wireless air interface protocol. Of course, the base station 310a and the network element 320i can also communicate with each other through an interface protocol between base stations and base stations. At this time, the network element 320i is also a base station relative to 310a. The RAN node 310 and the terminal 320 are sometimes referred to as communication apparatuses, for example, the network elements 310a and 310b in FIG. 3 can be understood as communication apparatuses with base station functions, and the network elements 320a-320j can be understood as communication apparatuses with terminal functions.

[0084] In one possible scenario, the RAN node can be a base station, an evolved Node B (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a next generation NodeB in a 3th generation (3G) mobile communication system, a base station in a future mobile communication system, etc. The RAN node can be a macro base station (e.g., 310a in FIG. 3), a micro base station or an indoor station (e.g., 310b in FIG. 3), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the RAN node can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, an access network device in a vehicle to everything (V2X) technology can be a road side unit (RSU). All or part of the functions of the RAN node in this application can also be implemented by software functions running on hardware, or by virtualized functions instantiated on a platform (e.g., a cloud platform). The RAN node in this application can also be a logical node, a logical module or software that can implement all or part of the functions of the RAN node.

[0085] In another possible scenario, a terminal is assisted by multiple RAN nodes to implement wireless access, and different RAN nodes respectively implement part of the functions of a base station. For example, the RAN node can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately arranged, or can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a radio frequency remote unit (RRU), an active antenna processing unit (AAU), or a remote radio head (RRH).

[0086] In different systems, the CU (or CU-CP and CU-UP), DU or RU can also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, the CU can also be referred to as O-CU (open CU), the DU can also be referred to as O-DU, the CU-CP can also be referred to as O-CU-CP, the CU-UP can also be referred to as O-CU-UP, and the RU can also be referred to as O-RU. For the convenience of description, the CU, CU-CP, CU-UP, DU and RU are taken as examples for description in this application. Any one of the CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0087] For example, in the example shown in FIG. 3, the terminal 320 can utilize the method provided in this application in the process of detecting SSBs (for example, SSBs transmitted by the nodes 310a and 310b respectively).

[0088] For example, the RAN node (or network device) and the terminal can be fixed in position or mobile. The RAN node and the terminal can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can be deployed on the water surface; can also be deployed on an airplane, a balloon and a man-made satellite. The embodiments of this application do not limit the application scenarios of the RAN node and the terminal.

[0089] In the embodiments of this application, the functions of the RAN node can also be performed by a module (such as a chip) in the RAN node or by a control subsystem containing RAN node functions. For example, the control subsystem containing RAN node functions can be a control center in application scenarios such as smart grid, industrial control, intelligent transportation and smart city. The functions of the terminal can also be performed by a module (such as a chip or a modem) in the terminal or by a device containing terminal functions.

[0090] In the embodiments of this application, as a possible implementation manner, the network device (or RAN) can include a CU, a DU and a RU, etc. As another possible implementation manner, the network device (or RAN) can be a CU, a DU or a RU, etc. The embodiments of this application do not limit here.

[0091] In the embodiments of the present application, the terminal can also be referred to as a terminal device, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc., or a device used to provide voice or data connectivity to a user, which can also be an Internet of Things device, or an entity on the user side used to receive or transmit signals, used to send uplink signals to a network device, or receive downlink signals from a network device, or send signals to another terminal device, or receive signals from another terminal device, or receive echo signals of signals sent by itself. For example, the terminal device includes handheld devices with wireless connection functions, vehicle-mounted devices, etc. The terminal can be widely applied to various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality (VR), augmented reality (AR), industrial control, self driving, remote medical, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc.

[0092] For example, the terminal device can be a mobile phone, a tablet computer, a notebook computer, a palm computer, a mobile internet device (MID), a wearable device (for example, a smart watch, a smart bracelet, a pedometer, smart glasses, etc.), a vehicle-mounted device (for example, a car, a bicycle, an electric vehicle, an airplane, a ship, a train, a high-speed rail, etc.), a satellite terminal, a VR device, an AR device, a smart point of sale (POS) machine, a customer-premises equipment (CPE), a light UE, a reduced capability UE (REDCAP UE), a wireless terminal in industrial control, a smart home device (for example, a refrigerator, a television, an air conditioner, an electricity meter, etc.), a smart robot, a mechanical arm, a workshop device, a wireless terminal in unmanned driving, a wireless terminal in remote medical treatment, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, or a wireless terminal in a smart home, a camera in smart transportation and a smart city, a flight device (for example, a smart robot, a hot air balloon, a drone, an airplane), and the like. The terminal device can also be a vehicle device, for example, a whole vehicle device, a vehicle-mounted module, a vehicle-mounted chip, an on board unit (OBU), or a telematics box (T-BOX), and the like. The terminal device can also be other devices with terminal functions, for example, the terminal device can also be a device with terminal functions in D2D communication, and the like. Embodiments of the present application do not limit the form of the terminal device.

[0093] It should be understood that in the embodiments of the present application, the "RAN node" can also be referred to as a network device, an access network device, or a wireless access network device, and the like. In the present application, the network device is used to represent the original access network device (such as a base station) unless otherwise specified.

[0094] It should be understood that the communication system shown in FIG. 3 is only exemplary and should not cause any limitation on the communication system applicable to the embodiments of the present application. For example, more or fewer network nodes, such as terminal devices, network devices (access network devices), and the like, can be included in the communication system shown in FIG. 3. The network devices or terminal devices included in FIG. 3 can be various forms of RAN nodes or terminal devices described above. The embodiments of the present application are not shown one by one in the figure.

[0095] The method for transmitting information provided by the present application is described below in conjunction with specific examples.

[0096] It should be understood that, in the present application, the network side device and the terminal are taken as examples as the execution subject of the execution method, and the method is described. As an example but not limitation, the terminal in the present application can be a terminal device, can be a component (chip, chip system, or processor) supporting the terminal device to implement the method, or can also be a logical module or software capable of implementing all or part of the terminal device functions. The network side device in the present application can also be a component (chip, chip system, or processor) supporting the network side device to implement the method, or can also be a logical module or software capable of implementing all or part of the network side device functions, such as CU, DU, or RU, etc. The present application embodiments are not limited here. In the following examples, the network side device is taken as an example of a network device.

[0097] The method for information transmission provided by the present application will be described below in combination with FIG. 4, which is a schematic flowchart of the method for information transmission according to an embodiment of the present application. The method 400 can be applied in the communication system or communication architecture shown in FIG. 3, and of course can also be applied in other communication scenarios or communication architectures where the above problems exist. The present application embodiments are not limited here.

[0098] As shown in FIG. 4, the method 400 shown in FIG. 4 can include S410 to S440. The various steps in the method 400 will be described in detail below in combination with FIG. 4.

[0099] S410, at least one second network device respectively sends first information to the first network device, the first information being used to indicate the transmission period of the SSB of the NES cell corresponding to each second network device and / or the SMTC information of the cell.

[0100] In the following examples, one second network device sending first information to the first network device will be taken as an example for description. It should be understood that the content of the first information sent by other second network devices to the first network device is similar to the content of the first information sent by the one second network device to the first network device. The specific description can be referred to the description of the first information below. For brevity, it will not be described here.

[0101] For example, the second network device can send first information to the first network device, the first information being used to indicate the transmission period of the SSB of the (served) second NES cell corresponding to the second network device and / or the SMTC information of the second NES cell.

[0102] Optionally, in the present application embodiment, the SMTC of the NES cell can also be expressed as “NES-SMTC” or “NES-SMTC”.

[0103] It can be understood that the transmission period of the SSB of the second NES cell can be multiple, and the second network device can transmit the SSB using one of the transmission periods of the SSB.

[0104] For example, the transmission period of the SSB in the second NES cell can include 5 ms, 10 ms, 20 ms, 40 ms, 80 ms, or 160 ms, and the like. The embodiments of the present application are not limited herein.

[0105] The SMTC information of the second NES cell can be understood as configuration information used by the terminal in the second NES cell to detect the SSB in the second NES cell. The SMTC information of the second NES cell can be configured by the second network device to the terminal in the second NES cell. For example, the SMTC information of the second NES cell (also referred to as the SMTC indication measurement time window configuration of the second NES cell) can include the SMTC indication period, the SMTC window offset, and the SMTC duration, and the like. The terminal in the second NES cell can determine the measurement period of the SSB according to the SMTC information of the second NES cell, and detect the SSB in the second NES cell according to the measurement period.

[0106] For example, the other second network devices can include a third network device and a fourth network device. The third network device can further transmit first information to the first network device, and the first information can be used to indicate the transmission period of the SSB of the third cell corresponding to the third network device and / or the SMTC information of the third cell, wherein the third cell can be an NES cell. The fourth network device can further transmit first information to the first network device, and the first information can be used to indicate the transmission period of the SSB of the fourth cell corresponding to the fourth network device and / or the SMTC information of the fourth cell, wherein the fourth cell can be an NES cell. That is, the first network device can receive the transmission period of the SSB of the NES cell corresponding to each second network device and / or the SMTC information of the NES cell transmitted by the multiple different network devices respectively.

[0107] In a possible implementation manner, the first network device can also transmit the transmission period of the SSB of the cell corresponding to the first network device and / or the SMTC information of the cell to the other network devices. For example, the first network device can transmit second information to the second network device, and the second information can be used to indicate the transmission period of the SSB of the first cell corresponding to the first network device and / or the SMTC information of the first cell.

[0108] In a possible implementation manner, the first cell can be an NES cell.

[0109] In a possible implementation, the second NES cell corresponding to the second network device and the first NES cell corresponding to the first network device can be adjacent cells.

[0110] In a possible implementation, the first NES cell and the second NES cell can be same-frequency cells.

[0111] In a possible implementation, the first NES cell and the second NES cell can be inter-frequency cells.

[0112] In a possible implementation, the first information can include first indication information and SMTC of the second NES cell, where the first indication information is used to indicate that the second NES cell is an NES cell, and the period indicated by the SMTC of the second NES cell is a maximum transmission period of an SSB corresponding to the second NES cell or a current transmission period of the SSB corresponding to the second NES cell.

[0113] Since the second cell served by the second network device is an NES cell (that is, the second NES cell), the transmission period of the SSB in the second NES cell can include multiple, and the first information includes first indication information used to indicate that the second NES cell is an NES cell, in this way, the first network device can be explicitly informed that the second NES cell is an NES cell, and the accuracy of the first network device determining that the second NES cell is an NES cell is improved.

[0114] If the period indicated by the SMTC of the second NES cell is the maximum transmission period of the SSB corresponding to the second NES cell. In this case, no matter what the actual transmission period of the SSB in the second NES cell is, the terminal (for example, a terminal in another cell) can detect the SSB of the second NES cell according to the period indicated by the SMTC of the second NES cell, and the accuracy of the terminal detecting the SSB of the second NES cell can be improved.

[0115] If the period indicated by the SMTC of the second NES cell is the current transmission period of the SSB corresponding to the second NES cell (that is, the actual transmission period of the SSB in the second NES cell), in this case, if the actual transmission period of the SSB in the second NES cell does not change or becomes smaller, the terminal in another cell can also detect the SSB of the second NES cell according to the period indicated by the SMTC of the second NES cell, and the accuracy of the terminal detecting the SSB of the second NES cell can be improved to a certain extent. Moreover, since the period indicated by the SMTC of the second NES cell is shorter, the mobility measurement of the terminal can be accelerated, and the mobility management performance is improved.

[0116] For example, the second network device can carry the first information described above through SMTC signaling. For example, the code implementation of the first information in the SMTC signaling can be as follows: "nes indication" can indicate that the second NES cell is an NES cell, and "SSB-MTC" can include the periodicity of the SMTC indication of the second NES cell.

[0117] It should be understood that in some possible implementations, the periodicity of the SMTC indication of the second NES cell can also be greater than the maximum transmission periodicity of the SSB corresponding to the second NES cell.

[0118] In a possible implementation, the first information can include the SMTC of the second NES cell, and the periodicity of the SMTC indication of the second NES cell is the maximum transmission periodicity of the SSB corresponding to the second NES cell (if the cell supports on-demand SSB or dynamic SSB periodicity adaptation, the periodicity in SSB-MTC is the largest periodicity to be used by the cell). Since the periodicity of the SMTC indication of the second NES cell is the maximum transmission periodicity of the SSB corresponding to the second NES cell. In this case, no matter what the actual transmission periodicity of the SSB in the second NES cell is, the terminal (for example, the terminal in other cells) can detect the SSB of the second NES cell according to the periodicity of the SMTC indication of the second NES cell, and the accuracy of the terminal detecting the SSB of the second NES cell can be improved.

[0119] For example, the second network device can carry the first information described above through SMTC signaling. For example, the code implementation of the first information in the SMTC signaling can be as follows: "nes indication" can indicate that the second NES cell is an NES cell, and "SSB-MTC" can include the periodicity of the SMTC indication of the second NES cell.

[0120] In a possible implementation, the first information can include a plurality of different transmission periods corresponding to the SSBs of the second NES cell. In this case, the actual transmission period used by the SSBs in the second NES cell is one of the plurality of different periods. Even if the actual transmission period used by the SSBs in the second NES cell changes, the switching is performed in the different transmission periods. For example, the first network device can configure the maximum transmission period of the SSBs corresponding to the second NES cell as the period indicated by the SMTC of the second NES cell. The terminals in the cells served by the first network device can all detect the SSBs of the second NES cell according to the period indicated by the SMTC of the second NES cell. The accuracy of the terminals detecting the SSBs of the second NES cell can be improved. The first network device determines the first configuration information by using the first information sent by each second network device, and the accuracy of the first configuration information can be improved, and the accuracy of the terminals (for example, the terminals in other cells) detecting the SSBs of the second NES cell can be improved.

[0121] For example, the first network device can carry the first information described above by using SMTC signaling. The code implementation of the SMTC signaling carrying the first information can be as follows: the "additionalperiodicity" can include a plurality of different transmission periods corresponding to the SSBs of the second NES cell.

[0125] S420, the first network device determines first configuration information according to the first information corresponding to each second network device, and the first configuration information includes: measurement configuration corresponding to M NES cells, and M is an integer greater than or equal to 1.

[0126] For example, the first network device can determine the first configuration information according to the first information respectively sent by the plurality of different network devices and the transmission period of the SSB in the first NES cell.

[0127] In a possible implementation, the first network device receives the first information respectively sent by the M second network devices, and each first information includes the transmission period of the SSB of the NES cell corresponding to the respective network device and / or SMTC information. The first network device can obtain the transmission period of the SSB corresponding to the M NES cells respectively. One network device (that is, one second network device) can correspond to one NES cell. The first network device can determine the measurement configuration corresponding to the M NES cells according to the above information.

[0128] In a possible implementation, the first network device receives the first information respectively sent by the A second network devices, and each first information includes the transmission period of the SSB of the NES cell corresponding to the respective network device and / or SMTC information. The first network device can obtain the transmission period of the SSB corresponding to the M NES cells respectively. One second network device can correspond to at least one NES cell. The value of A can be less than M. The first network device can determine the measurement configuration corresponding to the M NES cells according to the above information.

[0129] In a possible implementation, the measurement configuration corresponding to the M NES cells can include the SMTC corresponding to the plurality of NES cells.

[0130] In a possible implementation, the measurement configuration corresponding to the M NES cells can further include other measurement configurations, for example, include the SSB measurement (ssb-to Measure) configuration corresponding to the plurality of NES cells. The embodiments of the present application are not limited in this regard, as long as the measurement configuration corresponding to the M NES cells can be used for the terminal to detect the SSB.

[0131] For example, the SMTC can include the period indicated by the SMTC, the offset of the SMTC window, and the SMTC duration.

[0132] In a possible implementation, the plurality of NES cells can include the intra-frequency cells and the inter-frequency cells. That is, the plurality of NES cells can be composed of the intra-frequency cells and the inter-frequency cells.

[0133] In a possible implementation, the plurality of NES cells can all be intra-frequency cells or inter-frequency cells.

[0134] In a possible implementation, the M NES cells can all be the neighboring cells of the first NES cell.

[0135] For example, if the first network device respectively receives the first information from the second network device, the third network device and the fourth network device, the M NES cells in the first configuration information include: the second NES cell corresponding to the second network device, the third NES cell corresponding to the third network device, the fourth NES cell corresponding to the fourth network device, and the like.

[0136] Optionally, the M NES cells in the first configuration information can further include: the first NES cell corresponding to the first network device.

[0137] The process of determining the first configuration information by the first network device will be illustrated below.

[0138] In a possible implementation, if the first network device receives a maximum transmission period of SSBs corresponding to M NES cells respectively, each NES cell corresponds to one SSB, and there are M values (i.e., M maximum transmission periods of SSBs) in total. In this case, the first network device can determine the maximum value in the M values, which is assumed to be M L The first configuration information can include: one SMTC (also referred to as the first SMTC) and the identifiers of the M NES cells, the period indicated by the first SMTC is M L , and the M NES cells all correspond to the first SMTC. When detecting the SSB of any one of the M NES cells, the terminal can use the period M L indicated by the first SMTC to perform the detection.

[0139] That is, the first configuration information can include: the first SMTC and the identifiers of the M NES cells, the M NES cells all correspond to the first SMTC, and the period indicated by the first SMTC is the maximum value in the maximum transmission periods of SSBs corresponding to the plurality of NES cells (e.g., the M NES cells) respectively.

[0140] For example, the first configuration information can include: one SMTC (the first SMTC) and one cell identifier list (PCl List), the cell identifier list includes the identifiers of the plurality of NES cells, and the NES cells identified in the cell identifier list all correspond to the first SMTC.

[0141] In this way, on the one hand, the overhead of the first configuration information is small, and the communication resources used to transmit the first configuration information can be reduced. On the other hand, it can be ensured that the terminal can detect the SSB of any one of the cells in the cell identifier list using the SMTC, and the accuracy of detecting the SSB of the NES cell by the terminal can be improved, and detection abnormalities can be avoided.

[0142] It should be understood that in the embodiments of the present application, the first SMTC and the SMTC1 are different SMTCs, and the meanings represented are different. The first SMTC represents an SMTC corresponding to at least one NES cell. The cell corresponding to the SMTC1 does not distinguish between NES cells and non-NES cells.

[0143] In a possible implementation, if the first network device receives M SMTCs corresponding to M NES cells respectively, one SMTC corresponds to one cell, one SMTC indicates a period (i.e., a measurement time window period) corresponding to one NES cell, and there are M values in total (i.e., M periods indicated by M SMTCs, and there are M periods in total). In this case, the first network device can determine a maximum value in the M values, which is assumed to be M T Then, the first configuration information can include one SMTC (which can also be referred to as a first SMTC) and identifiers of the M NES cells. The first SMTC indicates a period M T , and the M NES cells all correspond to the first SMTC. When detecting an SSB of any one of the M NES cells, the terminal can use the period M T indicated by the first SMTC to perform detection.

[0144] That is, the first configuration information can include the first SMTC and identifiers of the M NES cells. The M NES cells all correspond to the first SMTC, and the period indicated by the first SMTC is a maximum value in periods indicated by SMTCs corresponding to the M NES cells respectively.

[0145] For example, the first configuration information can include one SMTC (a first SMTC) and a cell identifier list (PCl List). The cell identifier list includes identifiers of a plurality of NES cells. The NES cells identified in the cell identifier list all correspond to the first SMTC.

[0146] In this way, on the one hand, the first configuration information has a small overhead, and can reduce communication resources used to transmit the first configuration information. On the other hand, it can also ensure that the terminal can detect an SSB of any one of the cells in the cell identifier list using the SMTC, and can improve the accuracy of the terminal detecting the SSB of the NES cell, and avoid detection abnormalities.

[0147] In a possible implementation, if the second network device receives M current transmission periods of SSBs corresponding to M NES cells respectively, one NES cell corresponds to one current transmission period of an SSB, and there are M values in total (M current transmission periods of SSBs). In this case, the second network device can determine a maximum value in the M values, which is assumed to be M sThe first configuration information can include one SMTC (may also be referred to as a first SMTC) and the identification of the M NES cells, the period indicated by the first SMTC being the maximum of the current transmission periods of the SSBs of the M NES cells. s The M NES cells all correspond to the first SMTC. When detecting the SSB of any one of the M NES cells, the terminal can use the period indicated by the first SMTC to perform the detection.

[0148] That is, the first configuration information can include the first SMTC and the identification of the M NES cells, the M NES cells all corresponding to the first SMTC, and the period indicated by the first SMTC being the maximum of the current transmission periods of the SSBs of the M NES cells.

[0149] For example, the configuration information can include the first SMTC and a cell identification list (PCl List), the cell identification list including the identification of a plurality of NES cells, and the cells in the cell identification list all corresponding to the first SMTC.

[0150] In this way, on the one hand, the first configuration information has a small overhead, and the communication resources used to transmit the first configuration information can be reduced. On the other hand, if the transmission periods of the SSBs of the NES cells identified in the cell identification list are unchanged or reduced, the terminal can use the SMTC to detect the SSB of any one of the cells in the cell identification list, the accuracy of the terminal detecting the SSB of the NES cell is improved, and detection abnormalities are avoided.

[0151] In a possible implementation, if the first network device receives M maximum transmission periods of SSBs corresponding to M NES cells respectively, and each NES cell corresponds to one maximum transmission period of SSB, there are M values in total (i.e., M maximum transmission periods of SSB). In this case, the second network device can group the M values, for example, group multiple values that are the same or differ slightly. Suppose that there are S groups in total, that is, the M NES cells are divided into S groups, each group including one or more NES cells (i.e., including the identifier of one or more NES cells), or the identifiers of the M NES cells are divided into S cell identifier lists, each cell identifier list including the identifier of one or more NES cells. Each group (or each cell identifier list) corresponds to one SMTC, and there are S SMTCs in total. The period indicated by the SMTC corresponding to a certain group (a certain cell identifier list) can be: the maximum value in the maximum transmission periods of SSB corresponding to the NES cells included in the group; or the period indicated by the SMTC corresponding to a certain cell identifier list can be: the maximum value in the maximum transmission periods of SSB corresponding to the NES cells indicated by the cell identifier list, and the first configuration information can include: S SMTCs and S groups of NES cell identifiers (or S NES cell identifier lists), each group of NES cell identifiers (each cell identifier list) corresponding to one SMTC, and each group of NES cell identifiers (each cell identifier list) including at least one NES cell identifier.

[0152] For example, if the M NES cells are divided into four groups in total, each group of NES cell identifiers corresponds to one SMTC.

[0153] For example, the first group of NES cell identifiers includes the identifiers of NES cell 1, NES cell 3, and NES cell 4 respectively. NES cell 4 corresponds to the maximum maximum transmission period of SSB, and the SMTC (which can be referred to as the second SMTC) corresponding to the first group of NES cell identifiers indicates the period of the maximum transmission period of SSB corresponding to NES cell 4.

[0154] The second group of NES cell identifiers includes the identifiers of NES cell 2, NES cell 6, and NES cell 7 respectively, and NES cell 2 corresponds to the maximum maximum transmission period of SSB, and the SMTC corresponding to the second group of NES cell identifiers indicates the period of the maximum transmission period of SSB corresponding to NES cell 2.

[0155] The third group of NES cell identities includes: identities of NES cell 5, NES cell 9, and NES cell 12 respectively. Wherein, the maximum transmission period of the SSB corresponding to NES cell 12 is the largest, and thus the period indicated by the SMTC corresponding to the third group of NES cell identities can be the maximum transmission period of the SSB corresponding to NES cell 12.

[0156] The fourth group of NES cell identities includes: identities of NES cell 8, NES cell 10, and NES cell 11 respectively, wherein the maximum transmission period of the SSB corresponding to NES cell 10 is the largest, and thus the period indicated by the SMTC corresponding to the fourth group of NES cell identities can be the maximum transmission period of the SSB corresponding to NES cell 10.

[0157] When detecting the SSB of any one of the first group of NES cells, the terminal can use the period indicated by the SMTC corresponding to the first group of NES cell identities for detection. When detecting the SSB of any one of the second group of NES cells, the terminal can use the period indicated by the SMTC corresponding to the second group of NES cell identities for detection.

[0158] It should be understood that in the embodiments of the present application, the second SMTC and SMTC2 are different SMTCs, and represent different meanings. The second SMTC represents the SMTC corresponding to at least one NES cell. The cell corresponding to SMTC2 is not distinguished between NES cells and non-NES cells.

[0159] That is, the first configuration information includes: a plurality of different SMTCs and identities of M NES cells, each SMTC corresponding to the identity of at least one NES cell. The period indicated by each SMTC can be the maximum value in the maximum transmission periods of the SSBs corresponding to the at least one NES cell corresponding to the SMTC respectively. Or, the first configuration information includes: S SMTCs and S cell identity lists, each SMTC corresponding to a cell identity list, and each cell identity list including the identity of at least one NES cell. The period indicated by each SMTC can be the maximum value in the maximum transmission periods of the SSBs corresponding to the at least one NES cell indicated by the cell identity list corresponding to the SMTC respectively.

[0160] For example, in combination with the above example, the first configuration information can include: 4 SMTCs and 4 cell identity lists (or 4 groups of cell identities), each SMTC corresponding to a cell identity list (PCl List), and the period indicated by one SMTC can be the maximum value in the maximum transmission periods of the SSBs corresponding to the NES cells identified in the cell identity list corresponding to the SMTC respectively.

[0161] In a possible implementation, the number of SMTCs included in the first configuration information can be less than M, that is, S can be less than M, each SMTC corresponds to the identity of at least one NES cell, and the number of NES cells corresponding to each SMTC can be the same or different. That is, the first configuration information includes: S SMTCs and the identities of M NES cells corresponding to the SMTCs respectively, S is less than M, and one SMTC corresponds to one or more NES cells.

[0162] In this way, in the case where the first configuration information includes multiple different SMTCs and the identities of multiple NES cells, different NES cells can correspond to different SMTCs, which can improve the flexibility of the configuration of the NES corresponding to the SMTC, the terminal can detect the SSB of the NES cell according to the SMTC corresponding to the NES cell that needs to be measured, and since a certain SMTC matches part of the NES cells, instead of being the maximum value in the maximum transmission period of the SSB corresponding to all NES cells, the period indicated by the SMTC can be relatively small, which can improve the accuracy of the terminal detecting the SSB of the NES cell corresponding to the SMTC to a certain extent, can speed up the mobility measurement of the terminal, and improve the mobility management performance.

[0163] In a possible implementation, if the first network device receives M maximum transmission periods of SSBs corresponding to M NES cells respectively, each NES cell corresponds to one maximum transmission period of SSB, and there are M values (that is, M maximum transmission periods of SSB) in total. In this case, if the M values are all different or differ greatly, the first network device can take the maximum transmission period of the SSB corresponding to each NES cell as the period indicated by the SMTC corresponding to the NES cell, that is, one SMTC corresponds to one NES cell, the period indicated by the SMTC is the maximum transmission period of the SSB of the NES cell corresponding to the SMTC, and the number of SMTCs is the same as the number of NES cells. That is, the first configuration information includes: M SMTCs and the identities of M NES cells corresponding to the SMTCs respectively, one SMTC corresponds to one NES cell, and the SMTC and the NES cell are in a one-to-one relationship.

[0164] In other words, the number of SMTCs included in the first configuration information can be equal to M, that is, the number of S can be equal to M, and each SMTC corresponds to the identity of one NES cell. Each cell identity list includes the identity of one NES cell. That is, the first configuration information includes: M SMTCs and the identities of M NES cells corresponding to the SMTCs respectively, one SMTC corresponds to one NES cell.

[0165] In this way, one SMTC corresponds to one NES cell, different NES cells correspond to different SMTCs, which can improve the flexibility of the NES corresponding SMTC configuration, and the terminal can detect the SSB of the NES cell according to the NES cell corresponding SMTC to be measured, since a certain SMTC matches one NES cell, instead of matching all NESs, the period indicated by the SMTC can be relatively small, which can improve the accuracy of the terminal detecting the SSB of the NES cell corresponding to the SMTC, speed up the mobility measurement of the terminal, and improve the mobility management performance.

[0166] In a possible implementation, if the first network device receives a plurality of different transmission periods of the SSB corresponding to the NES cell respectively sent by the M network devices (M second network devices), that is, each second network device sends a plurality of different transmission periods of the SSB of its own cell to the first network device, the first information includes a plurality of different transmission periods corresponding to the SSB of each cell. In this case, the first network device can determine the maximum transmission period of the SSB corresponding to each cell received, and if the first network device determines a total of M maximum transmission periods of the SSB corresponding to the M NES cells respectively, each NES cell corresponds to one maximum transmission period of the SSB, and there are a total of M values (that is, M maximum transmission periods of the SSB). In this case, the first network device can also determine the first configuration information by using the N maximum transmission periods of the SSB by the above method, for example, the first configuration information includes a first SMTC and the identification of the M NES cells, the M NES cells all correspond to the first SMTC, and the period indicated by the first SMTC is the maximum value in the maximum transmission periods of the SSB corresponding to the plurality of NES cells (for example, M NES cells) respectively. Or, the first configuration information includes a plurality of different SMTCs and the identification of the M NES cells, each SMTC corresponds to the identification of at least one NES cell. The period indicated by each SMTC can be the maximum value in the maximum transmission periods of the SSB corresponding to at least one NES cell corresponding to the SMTC respectively. Or, the first configuration information includes M SMTCs and the identification of the M NES cells respectively, one SMTC corresponds to one NES cell, and the period indicated by one SMTC is the maximum transmission period of the SSB of the NES cell corresponding to the SMTC. For specific description, reference can be made to the above description, and details are not described herein for brevity.

[0167] In a possible implementation, if the first network device receives M SMTCs corresponding to M NES cells respectively, one SMTC corresponds to one cell, and one SMTC indicates a period (i.e., a measurement time window period) corresponding to one NES cell, there are M values (i.e., M periods indicated by the M SMTCs, and there are M periods in total). In this case, the second network device can group the M values, for example, group multiple values that are the same or differ slightly. Assume that there are S groups, that is, the M NES cells are divided into S groups, each group including one or more NES cells (i.e., each group including the identifier of one or more NES cells), or the identifiers of the M NES cells are divided into S cell identifier lists, each cell identifier list including the identifier of one or more NES cells. Each group (or each cell identifier list) corresponds to one SMTC, and there are S SMTCs in total. The period indicated by the SMTC corresponding to a certain group (a certain cell identifier list) can be: the maximum value in the periods indicated by the SMTCs corresponding to the NES cells included in the group; or the period indicated by the SMTC corresponding to a certain cell identifier list can be: the maximum value in the periods indicated by the SMTCs corresponding to the NES cells indicated by the cell identifier list.

[0168] The first configuration information can include: S SMTCs and S groups of NES cell identifiers (or S NES cell identifier lists), each group of NES cell identifiers (each cell identifier list) corresponding to one SMTC, and each group of NES cell identifiers (each cell identifier list) including at least one NES cell identifier. The period indicated by the SMTC corresponding to each group is: the maximum value in the periods indicated by the SMTCs corresponding to the NES cells indicated by each group of cell identifier lists.

[0169] That is, the first configuration information includes: multiple different SMTCs and the identifiers of the M NES cells, each SMTC corresponding to the identifier of at least one NES cell. The period indicated by each SMTC can be the maximum value in the periods indicated by the SMTCs corresponding to the at least one NES cell corresponding to the SMTC.

[0170] In a possible implementation, the number of SMTCs included in the first configuration information can be less than M, that is, the value of S can be less than M, and each SMTC corresponds to the identifier of at least one NES cell. The number of NES cells corresponding to each SMTC can be the same or different. That is, the first configuration information includes S SMTCs and the identifiers of the M NES cells respectively, the value of S is less than M, and one SMTC corresponds to one or more NES cells.

[0171] In this way, one SMTC corresponds to one NES cell, different NES cells correspond to different SMTCs, the flexibility of the SMTC configuration corresponding to the NES can be improved, the terminal can detect the SSB of the NES cell according to the SMTC corresponding to the NES cell to be measured, since one SMTC matches one NES cell instead of all NES cells, the period indicated by the SMTC can be relatively small, the accuracy of the terminal detecting the SSB of the NES cell corresponding to the SMTC is improved, the mobility measurement of the terminal is accelerated, and the mobility management performance is improved.

[0172] In a possible implementation, if the first network device receives M SMTCs corresponding to M NES cells respectively, one SMTC corresponds to one cell, one SMTC indicates a period (i.e., a measurement time window period) corresponding to one NES cell, and there are M values in total (i.e., M periods indicated by M SMTCs in total). In this case, the first network device can determine, as the period indicated by the SMTC corresponding to each NES cell, the period indicated by the SMTC corresponding to each NES cell in the first configuration information. That is, the first configuration information includes M SMTCs and identifiers of M NES cells corresponding to the M SMTCs respectively, one SMTC corresponds to one NES cell, and the SMTC and the NES cell are in a one-to-one relationship.

[0173] In this way, one SMTC corresponds to one NES cell, different NES cells correspond to different SMTCs, the flexibility of the SMTC configuration corresponding to the NES can be improved, the terminal can detect the SSB of the NES cell according to the SMTC corresponding to the NES cell to be measured, since one SMTC matches one NES cell instead of all NES cells, the period indicated by the SMTC can be relatively small, the accuracy of the terminal detecting the SSB of the NES cell corresponding to the SMTC is improved, the mobility measurement of the terminal is accelerated, and the mobility management performance is improved.

[0174] S430, the first network device sends the first configuration information to the first terminal.

[0175] The first terminal can be a terminal provided with communication services by the first network device, or in other words, the first terminal can be a terminal in the first cell.

[0176] For example, the first network device can send the first configuration information to the first terminal device through a measurement object (MO).

[0177] It should be understood that the first configuration information can include SMTC corresponding to at least one NES cell for intra-frequency measurement, or the first configuration information can include SMTC corresponding to at least one NES cell for inter-frequency measurement, or the first configuration information can include SMTC corresponding to at least one NES cell for intra-frequency measurement and inter-frequency measurement. That is, the first configuration information can be applicable to both intra-frequency measurement (intra-frequency cell) and / or inter-frequency measurement (inter-frequency cell). For example, for intra-frequency measurement (intra-frequency cell) and inter-frequency measurement (inter-frequency cell), the SMTC (SMTC_NES) corresponding to the newly added network energy saving can be configured separately.

[0178] In a possible implementation, the first configuration information includes one SMTC and identifiers of a plurality of NES cells, and the plurality of NES cells correspond to the SMTC. For example, the first configuration information can include a first SMTC and a cell identifier list (PCl List), and the cell identifier list includes identifiers of a plurality of NES cells, and the cells identified in the cell identifier list correspond to the first SMTC.

[0179] In this way, the first configuration information has a small overhead, and the communication resources used by the first configuration information can be reduced.

[0180] For example, the code implementation of the first configuration information carried in the MO can be as follows: the "SSB-MTC-NES" can include the first SMTC and the cell identifier list. In other words, the SMTC configuration message of the NES cell can be added in the "SSB-MTC" message.

[0181] In a possible implementation, the first configuration information includes M SMTCs and identifiers of M NES cells corresponding to the M SMTCs respectively, and one SMTC corresponds to one NES cell; or the first configuration information includes S SMTCs and identifiers of M NES cells corresponding to the S SMTCs respectively, and S is less than M, and one SMTC corresponds to one or more NES cells.

[0182] For example, the first configuration information includes a plurality of SMTCs and a plurality of cell identifier lists (PCl List), each SMTC corresponds to one cell identifier list (PCl List), and each cell identifier list includes identifiers of at least one NES cell. The number of SMTCs is the same as the number of cell identifier lists. The number of SMTCs (S) can be less than or equal to M.

[0183] For example, the code implementation of the first configuration information carried in the MO can be as follows, where the "SSB-MTC NES List" can include a list of cell identifiers corresponding to different SMTCs. "Num NES" indicates the number of SMTCs (i.e., NES SMTCs) supported by the configuration.

[0184] At S440, the first terminal detects the SSB of the NES cell according to the first configuration information.

[0185] For example, the first terminal can obtain, from the second network device, the identifiers of one or more (e.g., N) NES cells that need to be detected. Using the received first configuration information, the first terminal determines the SMTCs corresponding to the N NES cells according to the identifiers of the N NES cells. According to the periods indicated by the SMTCs corresponding to the N NES cells, the first terminal determines the measurement periods corresponding to the N NES cells, and detects the SSBs of the N NES cells according to the measurement periods corresponding to the N NES cells, respectively.

[0186] It should be understood that the M NES cells in the first configuration information include the N NES cells described above. In other words, the identifiers of the M NES cells in the first configuration information include the identifiers of the N NES cells described above.

[0187] For example, if the first configuration information includes a first SMTC and identifiers of M NES cells, where the M NES cells all correspond to the first SMTC, in this case, the N NES cells all correspond to the first SMTC, and the first terminal can determine the measurement period using the period indicated by the first SMTC, and detect the SSBs of the N NES cells using the measurement period, respectively. This can ensure that the first terminal can detect the SSBs of the N NES cells, improve the accuracy of the terminal in detecting the SSBs of the NES cells, and avoid detection abnormalities.

[0188] For another example, if the first configuration information includes S SMTCs and identifiers of M NES cells, where S is less than M, and one SMTC corresponds to one or more NES cells. In this case, for each NES cell in the N NES cells, the first terminal needs to determine the SMTC corresponding to the NES cell using the identifier of the NES cell. Different NES cells can correspond to the same SMTC. The first terminal determines the measurement period corresponding to the NES cell using the period indicated by the SMTC corresponding to the NES cell, and detects the SSB of the corresponding NES cell using the measurement period. This can ensure that the first terminal can detect the SSB of the NES cell, improve the accuracy of the terminal in detecting the SSB of the NES cell, and avoid detection abnormalities. Moreover, this can accelerate the mobility measurement of the terminal and improve the performance of mobility management.

[0189] For example, for intra-frequency measurement, for a NES cell list (PCIList) configured with SMTC_NES parameters, for a NES cell in the NES cell list (PCIList), the first terminal can determine the MTC_NES parameters used for calculating the measurement period using the SMTC_NES parameters corresponding to the NES cell (for example, including the period indicated by SMTC, etc.), calculate the measurement period using the determined SMTC_NES parameters, and then detect the SSB of the NES cell using the calculated measurement period.

[0190] For example, for inter-frequency measurement, for a NES cell list (PCIList) configured with SMTC_NES parameters, for a NES cell in the NES cell list (PCIList), the first terminal can determine the MTC_NES parameters used for calculating the measurement period using the SMTC_NES parameters corresponding to the NES cell (for example, including the period indicated by SMTC, etc.), calculate the measurement period using the determined SMTC_NES parameters, for example, including the calculation of the carrier-specific scaling factor (cssf), and then detect the SSB of the NES cell using the calculated measurement period.

[0191] For example, if the first configuration information includes: M SMTCs and the identifiers corresponding to M NES cells respectively, one SMTC corresponding to one NES cell. In this case, for each NES cell in the N NES cells, the first terminal needs to determine the SMTC corresponding to the NES cell using the identifier of the NES cell, different NES cells correspond to different SMTCs, the first terminal determines the measurement period corresponding to the NES cell using the period indicated by the SMTC corresponding to the NES cell, and detects the SSB of the corresponding NES cell using the measurement period. It can be ensured that the first terminal can detect the SSB of the NES cell, improve the accuracy of the terminal detecting the SSB of the NES cell, and avoid abnormal detection. And it can speed up the mobility measurement of the terminal and improve the mobility management performance.

[0192] For example, FIG. 5 shows a schematic diagram of the SSB side of the NES cell using the method provided in the present application and the prior art. The terminal in the second cell detects the SSB of the first NES cell. After the SSB period of the first NES cell changes, for example, as shown in FIG. 5, the transmission period of the SSB of the first NES cell changes from SSB period 1 to SSB period 2, and the value of SSB period 2 is greater than the value of SSB period 1. When SMTC1 configured by the prior art is detected, an abnormality check occurs. Using the method provided in the present application, the terminal can determine the SMTC corresponding to the first NES cell, and detect the SSB of the first NES cell using the SMTC corresponding to the first NES cell. In each detection position, the SSB can be detected, avoiding the abnormality of the SSB detection, and improving the accuracy of the terminal detecting the SSB of the NES cell.

[0193] In a possible implementation, the first network device can further send second configuration information to the first terminal, and the second configuration information includes: measurement configuration corresponding to the at least one non-NES cell.

[0194] For example, the measurement configuration corresponding to the at least one non-NES cell can include: one SMTC (for example, a third SMTC) and X non-NES cells corresponding to the respective identifiers, and the X non-NES cells correspond to the third SMTC. Wherein, the non-NES cell corresponds to SMTC1 in the existing protocol 38.133.

[0195] For another example, the measurement configuration corresponding to the at least one non-NES cell can include: X SMTCs and X non-NES cells corresponding to the respective identifiers, and one non-NES cell corresponds to one SMTC.

[0196] For another example, the measurement configuration corresponding to the at least one non-NES cell can include: Y SMTCs and X non-NES cells corresponding to the respective identifiers, and the value of Y is less than X, and one SMTC corresponds to one or more non-NES cells.

[0197] For example, the second configuration information corresponding to the code implementation can be as follows, wherein SMTC1 corresponds to the third SMTC described above.

[0198] For example, the measurement configuration corresponding to the at least one non-NES cell can include: X SMTCs and X non-NES cells corresponding to the respective identifiers, and one non-NES cell corresponds to one SMTC.

[0199] For another example, the measurement configuration corresponding to the at least one non-NES cell can include: Y SMTCs and X non-NES cells corresponding to the respective identifiers, and the value of Y is less than X, and one SMTC corresponds to one or more non-NES cells.

[0200] For example, the first terminal can acquire the identification corresponding to each non-NES cell to be detected from the second network device. Using the received second configuration information, the SMTC corresponding to each non-NES cell is determined according to the identification corresponding to each non-NES cell. According to the period indicated by the SMTC corresponding to each non-NES cell, the measurement period corresponding to each non-NES cell is determined, and the SSB of each non-NES cell is detected according to the measurement period corresponding to each non-NES cell.

[0201] In a possible implementation, the first configuration information and the second configuration information can be carried in the same signaling and sent to the first terminal. That is, the first configuration information and the second configuration information are carried in the same signaling (or message).

[0202] In a possible implementation, the first configuration information and the second configuration information can be carried in different signaling and sent to the first terminal. That is, the first configuration information and the second configuration information are carried in different signaling (or different messages).

[0203] The method for information transmission provided in the embodiments of the present application can be used for the first network device to acquire the transmission period of the SSB of the NES cell corresponding to each other network device and / or the SMTC information of the cell, and for the first network device to determine the measurement configuration corresponding to a plurality of NES cells according to the transmission period of the SSB of the NES cell corresponding to each other network device and / or the SMTC information. The measurement configuration corresponding to the plurality of NES cells includes the SMTC corresponding to the plurality of NES cells, different NES cells can correspond to the same or different SMTC, and the measurement configuration corresponding to the plurality of NES cells further includes the identification corresponding to each NES cell. The first network device sends the determined measurement configuration corresponding to the plurality of NES cells to the first terminal in the cell served by the first network device, and the first terminal can determine the SMTC corresponding to the NES cell to be detected according to the received information and the identification of the NES cell to be detected. The corresponding SMTC is configured for the NES cell, the accuracy of SSB detection of the NES cell by the terminal is improved, SSB detection abnormalities are avoided, and the mobility management performance is improved.
