Description

Communication method and communication device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on February 6, 2024, with application number 202410171609.9 and application name “Communication Method and Communication Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of wireless communications, and more particularly, to a communication method and a communication device. Background Art

[0003] In carrier aggregation (CA) technology, the primary cell (PCell) is responsible for radio resource control (RRC) communication with user equipment (UE). The secondary cell (SCell) is added during RRC reconfiguration to provide additional radio resources. In the secondary cell configuration scenario, the user equipment needs to measure the synchronization signal (SS) and physical broadcast channel (PBCH) block, i.e., the SSB signal, sent on the candidate cell. Only when the signal quality of the cell meets certain conditions can the cell be configured as a secondary cell. Or in the secondary cell switching scenario, the user equipment needs to measure the SSB signal on the target cell. When the signal quality of the target cell is good, the user equipment switches to the new target cell. In addition, when the secondary cell is configured, the secondary cell is in a deactivated state by default. When there is a service transmission demand on the network side, the activation process of the secondary cell will be started. At this time, the user equipment will perform channel state information (CSI) based on the SSB signal on the activated secondary cell and report the measurement results to the network equipment to activate the secondary cell.

[0004] Currently, for scenarios that do not require secondary cell configuration, switching, or activation, network devices always broadcast and send SSB signals, resulting in high power consumption of the network devices. Summary of the Invention

[0005] The present application provides a communication method and apparatus that can reduce the power consumption of network equipment and improve system performance.

[0006] In the first aspect, an embodiment of the present application provides a communication method, which can be executed by a network device or by a component of the network device (such as a chip, a chip system, or a circuit). This application is not limited to this. For the sake of convenience of description, the following is an example of execution by a network device. The method includes: periodically sending a first synchronization signal and a physical broadcast channel block SSB signal; receiving first indication information from a terminal device, the first indication information indicating the periodic sending of a second SSB signal, the sending period of the second SSB signal being less than the sending period of the first SSB signal; and periodically sending the second SSB signal based on the first indication information.

[0007] Based on the above solution, the network device can send the first SSB signal when there is no data service, and send the second SSB signal when there is a data service demand. Since the transmission period of the second SSB signal is short and the transmission period of the first SSB signal is long, the network device can maintain low power consumption when there is no service transmission, thereby achieving the effect of saving power consumption and reducing resource waste. At the same time, by triggering the first indication information through the terminal device to switch from the first SSB signal to the second SSB signal, no network configuration is required, which can speed up the switching delay of the second SSB signal.

[0008] In combination with the first aspect, in certain implementations of the first aspect, the first indication information is a wake-up signal WUS, or the first indication information is a channel sounding reference signal SRS, or the first indication information is carried in an uplink physical channel.

[0009] In combination with the first aspect, in some implementations of the first aspect, the method further includes: sending configuration information of the second SSB signal to the terminal device.

[0010] In combination with the first aspect, in certain implementations of the first aspect, the sending of the configuration information of the second SSB signal to the terminal device includes: sending multiple first configuration information to the terminal device; and sending second indication information to the terminal device, wherein the second indication information indicates that one of the multiple first configuration information is the configuration information of the second SSB signal.

[0011] Based on the above scheme, the second indication information is used to indicate one of multiple first configuration information to the terminal device, so that the configuration information of the second SSB signal can be flexibly adjusted according to the service transmission situation, thereby improving the performance of the communication system.

[0012] In combination with the first aspect, in certain implementations of the first aspect, the second indication information is carried in a media access control element MAC CE or in downlink control information DCI.

[0013] In combination with the first aspect, in certain implementations of the first aspect, each first configuration information among the multiple first configuration information includes the sending period of the SSB signal and the identification information corresponding to each first configuration information, and the second indication information is the identification information corresponding to one of the multiple first configuration information.

[0014] In combination with the first aspect, in some implementations of the first aspect, each first configuration information further includes SSB-based measurement timing configuration SMTC information.

[0015] In combination with the first aspect, in some implementations of the first aspect, the multiple first configuration information are carried in multiple radio resource control RRC messages.

[0016] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: periodically sending a third SSB signal, the sending period of the third SSB signal being greater than the sending period of the second SSB signal.

[0017] Based on this solution, after the service transmission is completed, the second SSB signal with a shorter period can be switched to the third SSB signal with a longer transmission period, which can save resources of network equipment and reduce energy consumption.

[0018] In combination with the first aspect, in some implementations of the first aspect, the method further includes: a sending period of the first SSB signal is one of 320ms, 480ms and 640ms.

[0019] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: a sending period of the second SSB signal is 5ms.

The method includes: periodically sending a first synchronization signal and a physical broadcast channel block SSB signal; sending a first indication information to a terminal device, the first indication information instructing the terminal device to periodically receive a second SSB signal, and the sending period of the second SSB signal is less than the sending period of the first SSB signal; and sending the second SSB signal based on the first indication information period.

[0021] Based on the above solution, the network device can send the first SSB signal when there is no data service, and send the second SSB signal when there is a data service demand. Since the transmission period of the second SSB signal is short and the transmission period of the first SSB signal is long, the network device can maintain low power consumption when there is no service transmission, thereby achieving the effect of saving power consumption and reducing resource waste. At the same time, the network device sends the first indication information to enable the terminal device to receive the second SSB signal, thereby ensuring that the terminal device receives the second SSB signal.

[0098] It is understandable that FIG1 is only a schematic diagram, and the wireless communication system may also include other devices, such as core network devices, wireless relay devices and / or wireless backhaul devices, which are not shown in FIG1 .

[0099] In this application, a base station sends downlink signals or downlink information to a terminal, and the downlink information is carried on a downlink channel; the terminal sends uplink signals or uplink information to the base station, and the uplink information is carried on an uplink channel. In order to communicate with the base station, the terminal needs to establish a wireless connection with the cell controlled by the base station. The cell with which the terminal has established a wireless connection is called the serving cell of the terminal. When the terminal communicates with the serving cell, it will also be subject to interference from signals in neighboring cells.

[0100] In this document, the physical uplink control channel (PUCCH) and the physical uplink shared channel (PUSCH) are merely examples of uplink control channels and uplink data channels, respectively. In different systems and scenarios, data channels and control channels may have different names, and the embodiments of the present application do not limit this.

[0101] In order to facilitate a better understanding of the technical solution of this application, some related technologies involved in the technical solution of this application are introduced.

[0102] 1. Cell: It is a set of resources managed by the base station, including frequency domain resources and spatial domain resources. The frequency domain resources of a cell include uplink frequency domain resources and / or downlink frequency domain resources; the spatial domain resources of a cell can be the spatial domain resources corresponding to a beam or a group of beams, and can also be understood as a cell corresponding to a specific physical coverage area. In an embodiment of the present application, different cells can be managed by different base stations. For example, cell #1 and cell #2 can be managed by different base stations. In this case, it can be said that cell #1 and cell #2 do not share the same site. Cell #1 and cell #2 can also be managed by the same base station and have the same baseband processing unit and / or radio frequency processing unit. This application does not limit this.

[0103] It should be noted that there is a one-to-one correspondence between cells and carriers, and the terms "cell" and "carrier" can be used interchangeably. In other words, the frequency band of a cell can be understood as the frequency band of the cell's corresponding carrier, and can also be referred to as the cell's operating frequency band or the cell's frequency band.

[0104] 2. Carrier aggregation (CA): This is the process of aggregating two or more component carriers (CCs) to support a larger transmission bandwidth. The CA technology in NR is used to increase the transmission bandwidth for a single user. Specifically, carrier aggregation technology can achieve multi-frequency resource integration. For example, CA technology can aggregate spectrum resources in the same or different frequency bands and provide them to terminals, thereby improving the utilization of the entire network resources and improving the user experience.

[0105] For ease of understanding, a brief introduction to CA technology is provided with reference to Figure 2. Figure 2 shows that the component carriers corresponding to cell #1, cell #2, and cell #3 are aggregated to provide service to the terminal. Cell #1 is the PCell, and cells #2 and #3 are SCells. The PCell is the cell where the terminal establishes an initial connection or reestablishes an RRC connection. The PCell is responsible for RRC communication with the terminal. The component carrier corresponding to the PCell is called the primary component carrier (PCC) (as shown in Figure 2). The downlink carrier of the PCell is called the DL PCC, and the uplink carrier of the PCell is called the UL PCC. SCells are added during RRC reconfiguration to provide additional radio resources. There is no RRC communication between the SCell and the UE. The component carriers corresponding to the SCell are called secondary component carriers (SCCs) (as shown in Figure 2, SCC#1 and SCC#2). The downlink carrier of the SCell is called the DL SCC, and the uplink carrier of the SCell is called the UL SCC.

[0106] Figure 3 is a schematic diagram of the configuration process of a secondary cell. Specifically, when the network device configures and adds a secondary cell, it will manually configure to establish a CA frequency set and the frequencies it contains. The cells corresponding to these frequencies are candidate secondary cells. After the terminal device establishes an RRC connection with the main cell, the main cell will combine the capabilities of the candidate secondary cells and the terminal device to determine the secondary cell that the terminal device needs to add, and send the relevant information of these secondary cells to the terminal device through the RRC reconfiguration message. The terminal device will add the secondary cell based on the relevant information of the secondary cell, as shown in Figure 3. When the terminal device is added, there are two ways to configure the secondary cell: blind configuration and measurement-based configuration. When blind configuration is used, the terminal device directly configures the secondary cell according to the secondary cell related information sent by the network device; when measurement-based configuration is used, the signal quality of the cell also needs to be considered. Only when the signal quality of the cell meets certain conditions can the cell be configured as a secondary cell.

[0107] NR defines two states for the secondary cell in R15, namely the activation state and the deactivation state. When the secondary cell is in the activation state and the cell is configured with a physical downlink control channel (PDCCH), the terminal device needs to monitor the PDCCH of the cell and transmit signals based on the network configuration and uplink and downlink scheduling information. When the secondary cell is in the deactivated state, the UE does not need to perform any uplink and downlink signal monitoring and transmission in the secondary cell. The activation state and deactivation state of the secondary cell can be switched through the medium access control control element (MAC CE) signaling, as shown in Figure 4.

[0108] Before introducing the solution of this application, the following points are explained.

[0109] (1) In this application, “indication” may include direct indication, indirect indication, explicit indication, and implicit indication. When describing that a certain indication information is used to indicate A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.

[0110] In this application, the information indicated by the indication information is referred to as the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, wherein there is an association between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can also be achieved with the help of the arrangement order of each information agreed in advance (for example, stipulated by the protocol), thereby reducing the indication overhead to a certain extent. In addition, the information to be indicated can be sent together as a whole, or it can be divided into multiple sub-information and sent separately, and the sending period and / or sending time of these sub-information can be the same or different.

[0111] (2) In this application, "sending" and "receiving" indicate the direction of signal transmission. For example, "sending information to XX" can be understood as the destination of the information being XX, which can include direct sending through the air interface, and also include indirect sending through the air interface by other units or modules. "Receiving information from YY" can be understood as the source of the information being YY, which can include direct receiving from YY through the air interface, and also include indirect receiving from YY through the air interface from other units or modules. "Sending" can also be understood as the "output" of the chip interface, and "receiving" can also be understood as the "input" of the chip interface. In other words, sending and receiving can be carried out between devices, for example, between a network device and a terminal device, or can be carried out within a device, for example, sending or receiving between components, modules, chips, software modules or hardware modules within the device through a bus, a line or an interface.

[0112] (3) In the various embodiments of this application, unless otherwise specified or there is a logical conflict, the terms and / or descriptions between different embodiments are consistent and can be referenced by each other. The technical features in different embodiments can be combined to form new embodiments based on their inherent logical relationships.

[0113] (4) In this application, the terms "first" and "second" are used for convenience of description only and are not intended to limit the scope of the embodiments of this application. They are not used to describe the order or precedence of features. It should be understood that the terms described in this manner may be interchangeable, where appropriate, to describe solutions other than the embodiments of this application.

[0114] The method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings. The embodiment provided by the present application can be applied to the communication system shown in FIG1 above without limitation.

[0115] In the following embodiments, terminal devices and network devices are used as examples for illustrative description, wherein the terminal device can be replaced by a component of the terminal device (such as a chip or circuit), and the network device can be replaced by a component of the network device (such as a chip or circuit).

[0116] Figure 5 is a schematic diagram of a first communication method 500 provided in an embodiment of the present application. Figure 5 shows a schematic flow of information interaction between a network device and a terminal device. The method 500 shown in Figure 5 may include the following steps.

[0117] S501, the network device periodically sends a first SSB signal.

[0118] S502, the terminal device sends a first indication message to the network device, where the first indication message indicates a periodic sending of a second SSB signal, where the sending period of the second SSB signal is less than the sending period of the first SSB signal.

[0119] It should be noted that the present application does not limit the first indication information, which may be a signal, and the signal may be a signal carried in a physical uplink channel, such as an uplink wake-up signal (WUS); or a signal not carried in a physical uplink channel, such as a sounding reference signal (SRS); in addition, the first indication information may also be information carried on an uplink physical channel, such as an indication field of uplink control information (UCI) carried on a PUCCH or PUSCH. In this case, the UCI sent by the terminal device to the network device includes an indication field carrying the first indication information, and the number of bits contained in the indication field may be one or more bits. For example, if the number of bits occupied by the indication field is 2, 00 indicates that the indication field does not carry the first indication information, or the first indication information does not instruct the network device to send a second SSB signal, and 11 indicates that the first indication information carried by the indication field instructs the network device to send a second SSB signal.

[0120] It should be noted that the present application solution does not limit the transmission period of the first SSB signal and the transmission period of the second SSB signal, as long as the transmission period of the first SSB signal is greater than the transmission period of the second SSB signal. Optionally, the range of the transmission period of the first SSB signal is [80ms, 640ms]. At this time, the transmission period of the first SSB signal can be 80ms, 160ms, 320ms, 480ms or 640ms, etc. Optionally, the range of the transmission period of the second SSB signal is less than 20ms, for example, it can be 5ms, 10ms, etc. Optionally, the range of the transmission period of the second SSB signal is less than 5ms, for example, it can be 3ms, etc.

[0121] S503, the network device sends a second SSB signal based on the first indication information period.

[0122] It should be noted that the network device only sends one SSB signal within a time period. In other words, if the network device sends a first SSB signal in a first time period, when the network device receives the first indication information, it will learn based on the first indication information that it needs to change the SSB signal it sends from the first SSB signal to a second SSB signal. At this time, the network device will stop periodically sending the first SSB signal and send the second SSB signal in the subsequent second time period.

[0123] S504, the terminal device receives a second SSB signal based on the first indication information period.

[0124] Specifically, after the terminal device sends the first indication information to the network device, the terminal device starts to receive the second SSB signal.

[0125] It will be appreciated that in this solution, the first and second SSB signals have different transmission periods. For example, if the transmission period of the first SSB signal is the first period, the transmission period of the second SSB signal is the second period, and the second period is shorter than the first period. The first SSB signal may be transmitted when the terminal device has no SSB signal measurement requirements, for example, when the network device and the terminal device are not transmitting data services or when the terminal device's secondary cell is deactivated. In such scenarios, the network device transmitting the first SSB signal with a longer period can enable the network device to maintain low power consumption, thereby saving energy. When the terminal device needs to measure using the SSB signal, i.e., when the terminal device has an SSB signal measurement requirement, for example, when the network device and the terminal device have data transmission requirements and a deactivated secondary cell needs to be activated; or when the terminal device needs to remeasure the secondary cell due to factors such as movement, rotation, or environmental changes, the network device transmitting the second SSB signal with a shorter period can reduce the SSB signal measurement latency, thereby achieving rapid activation and access to the secondary cell, thereby improving system performance.

[0126] In addition, in this solution, the terminal device sends a first indication message to instruct the network device to switch the period of the sent SSB signal, so that the terminal device can flexibly instruct the network device according to the uplink service requirements or the terminal device's own environment, thereby improving the system reliability and the efficiency of SSB signal period switching.

[0127] Figure 6 is a schematic diagram of a second communication method 600 provided in an embodiment of the present application. Figure 6 illustrates a schematic flow of information exchange between a network device and a terminal device. Compared to method 500, method 600 shown in Figure 6 further includes other interaction processes between the terminal device and the network device after receiving the second SSB signal. Specifically, the method shown in Figure 6 includes the following steps.

[0128] S601, the network device periodically sends a first SSB signal.

[0129] S602, the terminal device sends a first indication message to the network device, where the first indication message indicates the periodic sending of a second SSB signal, and the sending period of the second SSB signal is less than the sending period of the first SSB signal.

[0130] S603, the network device sends a second SSB signal based on the first indication information period.

[0131] S604, the terminal device receives a second SSB signal based on the first indication information period.

[0132] Specifically, the relevant descriptions in S601-S604 can refer to the descriptions in S501-S504 in the method 500 shown in Figure 5, and will not be repeated here.

[0133] S605, the terminal device obtains configuration information of the second SSB signal.

[0134] In some embodiments, the configuration information of the second SSB signal acquired by the terminal device is the configuration information of the second SSB signal preset in the terminal device and the network device. Wherein, "preset" may include pre-definition, for example, protocol definition. Wherein, "pre-definition" may be implemented by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in the network device and the terminal device, and this application does not limit its specific implementation method. At this time, the configuration information of the second SSB signal may include the transmission period of the second SSB signal and SSB-based measurement timing configuration (SMTC) information. Wherein, the SMTC information may include an SMTC period and an SMTC duration, the SMTC period being the measurement period of the second SSB signal, and the SMTC duration being the measurement duration of the second SSB signal. It should be noted that in order to ensure accurate and complete measurement of the second SSB signal, the SMTC period is at least equal to the transmission period of the second SSB signal, that is, the SMTC period may be the same as the transmission period of the second SSB signal, or may be greater than the transmission period of the second SSB signal.

[0135] It is understandable that the transmission period and SMTC information of the second SSB signal in the preset second SSB signal obtained by the terminal device are generally fixed values, that is, the configuration information of the second SSB signal is rarely changed after being configured in the terminal device once. For example, during factory configuration, the second SSB signal is configured by setting the default configuration information. Therefore, when the configuration information of the second SSB signal obtained by the terminal device comes from the preset information, the terminal device does not need to interact with other devices or decode the information, etc., and the accuracy of the configuration information of the second SSB signal can be guaranteed, thereby improving the stability of the system.

[0136] In other embodiments, the second SSB signal obtained by the terminal device is sent by the network device to the terminal device. In one achievable manner, the network device sends the configuration information of the second SSB signal to the terminal device. For example, the network device carries the configuration information of the second SSB signal through RRC reconfiguration signaling and sends it to the terminal device, so that after the terminal device receives the RRC reconfiguration signaling, it obtains the configuration information of the second SSB signal from the RRC reconfiguration signaling and measures the second SSB signal. In another achievable manner, as shown in Figure 7, the network device provides the terminal device with the configuration information of the second SSB signal by indicating one of the multiple first configuration information sent. Specifically, Figure 7 includes the following steps.

[0137] S701: A network device sends a plurality of first configuration information to a terminal device.

[0138] It should be noted that multiple first configuration information can be carried in the same message, or multiple first configuration information can be carried in multiple messages respectively, which is not limited in this application. Optionally, the multiple first configuration information is carried in RRC reconfiguration signaling and sent to the terminal device; or, the multiple first configuration information is carried in other configuration messages, which is not limited in this application.

[0139] Specifically, each first configuration information may include the transmission period of the second SSB signal, SMTC information, and identification information corresponding to each first configuration information. The transmission period of the second SSB signal and the SMTC information included in each first configuration information are not exactly the same, that is, when the transmission period of the second SSB signal included in each first configuration information is the same, the SMTC information included in each first configuration information is different; or, when the transmission period of the second SSB signal included in each first configuration information is different, the SMTC information included in each first configuration information may be the same or different. In other words, at least one of the transmission period and SMTC information of the second SSB signal contained in any two first configuration information is different. The SMTC information can refer to the above description and will not be repeated here. The identification information corresponding to the first configuration information may be the index, number, etc. corresponding to the first configuration information. Exemplarily, when a network device sends four first configuration information to a terminal device, namely, first configuration information #1, first configuration information #2, first configuration information #3, and first configuration information #4, first configuration information #1 includes the transmission period #1 of the second SSB signal, SMTC information #1, and identification information 1 of the first configuration information #1; first configuration information #2 includes the transmission period #2 of the second SSB signal, SMTC information #2, and identification information 2 of the first configuration information #2; first configuration information #3 includes the transmission period #3 of the second SSB signal, SMTC information #3, and identification information 3 of the first configuration information #3; and first configuration information #4 includes the transmission period #4 of the second SSB signal, SMTC information #4, and identification information 4 of the first configuration information #4. When transmission periods #1 to #4 are the same, SMTC information #1 to #4 are different; and when any two of transmission periods #1 to #4 are different, SMTC information #1 to #4 may be completely identical, completely different, or partially identical.

[0140] S702, the network device sends second indication information to the terminal device, where the second indication information indicates that one of the multiple first configuration information is configuration information of the second SSB signal.

[0141] Specifically, the second indication information is identification information corresponding to the first configuration information. Optionally, the second indication information is carried in a MAC CE or in downlink control information (DCI), etc. It can be understood that when the second indication information is carried in a MAC CE or in a DCI, the MAC CE or DCI sent by the network device to the terminal device includes an indication field of the second indication information, and the number of bits contained in the indication field may be one or more bits, and the value corresponding to the one or more bits is the identifier of the first configuration information.

[0142] S703, the terminal device determines the configuration information of the second SSB signal from multiple first configuration information according to the second indication information.

[0143] Specifically, when the terminal device receives the second indication information, it determines the identifier corresponding to the first configuration information through the value of the second indication information, thereby determining that the first configuration information corresponding to the identifier is the configuration information of the second SSB signal among multiple first configuration information.

[0144] It can be understood that when the configuration information of the second SSB signal is provided to the network device, the sending period of the second SSB signal can be flexibly designed. For example, the network device determines the sending period of the second SSB signal based on the current congestion of the downlink transmission resources, thereby improving the flexibility of the configuration of the second SSB signal and enabling the system to adapt to different scenarios.

[0145] S606, the terminal device measures the second SSB signal according to the configuration information of the second SSB signal and generates a first measurement result.

[0146] Specifically, after the terminal device obtains the configuration information of the second SSB signal, it uses the configuration information of the second SSB signal to measure the second SSB signal and generate a first measurement result. The first measurement result may be a layer 3 (L3) or layer 1 (L1) measurement result, or may be reference signal receiving power (RSRP) information, which is not limited in this application. The measurement process of L3 / L1 may refer to the description in the relevant protocol and will not be repeated here. Exemplarily, when the second SSB signal is used for secondary cell configuration, the network device may select a configured secondary cell for the terminal device based on the first measurement result. When the second SSB signal is used to activate the secondary cell, the first measurement result may be the RSRP information of the secondary cell generated during the activation of the secondary cell.

[0147] S607: The terminal device sends the first measurement result to the network device.

[0148] Specifically, after the terminal device obtains the first measurement result of the second SSB signal, the first measurement result is reported to the network device. Optionally, the first measurement result sent by the terminal device to the network device can be reported to the network device periodically or aperiodically, which is not limited in this application.

[0149] In some scenarios, if the terminal device measures the first SSB signal within the transmission time period of the first SSB signal, the method may further include the following steps.

[0150] S608, the terminal device obtains configuration information of the first SSB signal.

[0151] In some embodiments, the configuration information of the first SSB signal obtained by the terminal device comes from the configuration information preset in the terminal device and the network device. For example, through protocol definition, etc., this application is not limited. In other embodiments, the first SSB signal obtained by the terminal device is sent by the network device to the terminal device, for example, it is sent to the terminal device through RRC reconfiguration signaling. Among them, the configuration information of the first SSB signal includes the transmission period of the first SSB signal and the SMTC information corresponding to the first SSB signal. Among them, the SMTC information can refer to the description above and will not be repeated here. It can be understood that the SMTC period in the SMTC information corresponding to the first SSB signal is greater than or equal to the transmission period of the first SSB signal.

[0152] It should be noted that when the terminal device also measures the first SSB signal, since the terminal device obtains the SMTC information corresponding to the first SSB signal, when the terminal device obtains the configuration information of the second SSB signal in S605, the SMTC information corresponding to the second SSB signal can continue to use the SMTC information corresponding to the first SSB signal. In other words, the configuration information of the second SSB signal obtained by the terminal device may not include SMTC information, thereby reducing the delay for the terminal device to obtain the configuration information of the second SSB signal and saving resources for carrying the configuration information of the second SSB signal.

[0153] S609, the terminal device measures the first SSB signal according to the configuration information of the first SSB signal and generates a second measurement result.

[0154] S610: The terminal device sends a second measurement result to the network device.

[0155] Specifically, S609 and S610 may refer to the above-mentioned S606 and S607 respectively, and will not be repeated here.

[0156] In some scenarios, if the second SSB signal is used for secondary cell configuration, the network device can select a secondary cell to be configured for the terminal device based on the first measurement result. Specifically, please refer to the relevant description in Figure 3, which will not be repeated here. After the terminal device completes adding and configuring the secondary cell, the secondary cell defaults to a deactivated state. If the network device activates at least one configured secondary cell, method 600 may also include the following multiple steps.

[0157] S611, the network device sends third indication information to the terminal device, where the third indication information indicates activation of the secondary cell.

[0158] Specifically, the third indication information includes identification information of the secondary cell to be activated, for example, the ID of the secondary cell or the index of the secondary cell. In addition, the present application does not limit the message carrying the third indication information. Optionally, the third indication information is carried in MAC CE signaling. Exemplarily, when the third indication information is carried in MAC CE signaling, the MAC CE signaling includes an indication field carrying the third indication information, and the indication field is one or more bits, and the one or more bit values ​​are the identification information of the secondary cell.

[0159] S612: The terminal device activates the secondary cell based on the third indication information and generates a third measurement result.

[0160] Specifically, after the terminal device receives the third indication information, the terminal device performs time and frequency synchronization with the network device, and at the same time measures the channel state information reference signal (CSI-RS) of each secondary cell to obtain the channel state information (CSI) of each secondary cell, that is, the third measurement result, so that the network device can refer to the third measurement result for corresponding data scheduling. Generally speaking, CSI mainly includes three items: channel quality indicator (CQI) information, rank indicator (RI) information and precoding indicator (PMI) information, which are not limited in this application.

[0161] S613: The terminal device reports the third measurement result to the network device.

[0162] Specifically, after the terminal device activates the secondary cell, the terminal device reports the CSI of the secondary cell to the network device, and accordingly, the network device receives the CSI.

[0163] It is understood that when the network device receives a valid CSI measurement report reported by the terminal device, it indicates that the secondary cell has completed the activation process. After the secondary cell activation is complete, the network device and the terminal device can transmit data on the secondary cell. At this point, the secondary cell is in an activated state. For an activated cell, the network device can stop sending the second SSB signal on the secondary cell and resume sending a third SSB signal with a third period in a third time period. The period of the third SSB signal can be a relatively regular period, and the transmission period of the third SSB signal is greater than the transmission period of the second SSB signal. For example, the period of the third SSB signal is 20ms. Thereafter, the terminal device can periodically detect the third SSB signal. In one achievable embodiment, the network device can immediately stop sending the second SSB signal after receiving the third measurement result and start periodically sending the third SSB signal. In another achievable embodiment, the network device can continue to send the second SSB signal for a period of time and send the third SSB signal after sending the fourth indication information to the terminal device. The following describes the steps that may be included in method 600 based on the above different implementations.

[0164] When the third measurement result triggers the network device to periodically send a third SSB signal, method 600 includes S614 and S615.

[0165] S614, the network device sends a third SSB signal based on the third measurement result period, and the sending period of the third SSB signal is greater than the sending period of the second SSB signal.

[0166] Specifically, after the terminal device reports the third measurement result to the network device, the network device stops sending the second SSB signal according to the third measurement result, and starts to periodically send the third SSB signal.

[0167] S615, the terminal device periodically receives the third SSB signal.

[0168] Specifically, after the terminal device reports the third measurement result to the network device, the terminal device periodically receives the third SSB signal on the secondary cell.

[0169] When the fourth indication information triggers the network device to periodically send the third SSB signal, method 600 includes S616 to S618.

[0170] S616, the network device sends fourth indication information to the terminal device, and the fourth indication information instructs the network device to send a third SSB signal, and the sending period of the third SSB signal is greater than the sending period of the second SSB signal.

[0171] Specifically, after the network device receives the third measurement result, the network device can continue to send the second SSB signal for a period of time. When the data transmission between the network device and the terminal device is less, the network device sends a fourth indication information to the terminal device, instructing the network device to send the third SSB signal.

[0172] Optionally, the fourth indication information is carried in MAC CE or DCI.

[0173] S617, the network device periodically sends a third SSB signal.

[0174] It is understandable that the network device may send the third SSB signal after sending the fourth indication information; or, the network device may send the third SSB signal first and then send the fourth indication information to the terminal device; or, the network device may send the fourth indication information to the terminal device simultaneously with sending the third SSB signal. This application does not limit the order of S616 and S617.

[0175] S618, the terminal device receives a third SSB signal based on the fourth indication information period.

[0176] Specifically, after the terminal device receives the fourth indication information from the network device, the terminal device periodically receives the third SSB signal on the secondary cell.

[0177] Figure 8 is a schematic diagram of a third communication method 800 provided in an embodiment of the present application. Figure 8 shows a schematic flow of information interaction between a network device and a terminal device. It should be noted that in the method 500 shown in Figure 5, triggering the network device to switch the periodically transmitted first SSB signal to the periodically transmitted second SSB signal is triggered by the first indication information sent by the terminal device. For example, it may be that the terminal device has a higher uplink data transmission requirement, or the terminal device sends it to the network device according to the requirements of secondary cell activation, switching, etc. Compared with method 500, in the method 800 shown in Figure 8, triggering the network device to switch the first SSB signal to the second SSB signal is implemented by the network device. For example, when the network device determines that the secondary cell of the terminal device needs to be activated according to the uplink and downlink service requirements, the method 800 shown in Figure 8 may be executed. The method 800 shown in Figure 8 may include the following multiple steps.

[0178] S801, the network device periodically sends a first SSB signal.

[0179] S802, the network device sends fifth indication information to the terminal device, and the fifth indication information instructs the terminal device to periodically receive a second SSB signal, and the sending period of the second SSB signal is smaller than the sending period of the first SSB signal.

[0180] Optionally, the fifth indication information includes identification information of the secondary cell. For example, when the fifth indication information occupies multiple bits, the values ​​of the multiple bits are identification information of the secondary cell. At this time, the terminal device can determine which secondary cell needs to be activated based on the value of the bit, and receive the second SSB signal on the corresponding secondary cell. Optionally, or, the network device uses a bitmap to indicate the correspondence between the identification of the secondary cell and whether it is activated, so that the terminal device can know on which secondary cells the network device has sent the second SSB signal according to the bitmap. When the correspondence between the identification of the secondary cell and whether it is activated is determined according to the bitmap, the multiple bits in the fifth indication information received by the terminal device correspond to the identification information of the secondary cell from low to high in sequence from low to high, so that the terminal device can determine which secondary cells are activated according to the bitmap after receiving the bitmap. Exemplarily, when the network device configures 5 secondary cells for the terminal device, the fifth indication information corresponds to 5 bits, and the 5-bit fifth indication information corresponds to secondary cell #5, secondary cell #4, secondary cell #3, secondary cell #2 and secondary cell #1 from the highest bit to the lowest bit. When the fifth indication information is 11001, the fifth indication information indicates that secondary cell #5, secondary cell #4 and secondary cell #1 are cells that need to be activated, that is, the terminal device receives the second SSB signal on secondary cell #5, secondary cell #4 and secondary cell #1 respectively. It can be understood that the above-mentioned fifth indication information is explained by taking the bit position 1 to represent the activated cell as an example, and the bit position can also be 0 to indicate that the second SSB signal is received on the secondary cell corresponding to the bit position, and this application does not limit it.

[0181] It should be noted that the present application does not limit the fifth indication information. For example, the fifth indication information may be indication information carried in MAC CE signaling.

[0182] In addition, the range of the sending period of the first SSB signal and the sending period of the second SSB signal can refer to the description of Figure 5 above, and will not be repeated here.

[0183] S803, the network device periodically sends a second SSB signal.

[0184] It should be noted that, in this solution, the order of S802 and S803 is not limited in this application. The network device may first send the second SSB signal and then send the fifth indication information, or the network device may send the fifth indication information at the same time as sending the second SSB signal, or it may first send the fifth indication information and then send the second SSB signal.

[0185] S804, the terminal device receives a second SSB signal based on the fifth indication information period.

[0186] Specifically, after receiving the fifth indication information, the terminal device receives the second SSB signal according to the fifth indication information period.

[0187] It is understandable that the first SSB signal can be sent when the network device has no SSB signal measurement requirement, for example, the network device and the terminal device have no data service transmission, the secondary cell of the terminal device is in a deactivated state, and other scenarios. At this time, the network device sends a first SSB signal with a longer period, which can enable the network device to maintain low power consumption and achieve the purpose of saving energy. When the network device needs to use the SSB signal for measurement, that is, the network device has an SSB signal measurement requirement, for example, the network device and the terminal device have a data transmission requirement and need to activate the deactivated secondary cell, the network device sends a second SSB signal with a shorter period, which can reduce the measurement delay of the SSB signal, thereby achieving the purpose of quickly activating the secondary cell and improving system performance.

[0188] In addition, in this solution, the network device sends the fifth indication information to instruct the terminal device to receive the second SSB signal, so that the network device can flexibly instruct the terminal device according to business needs, thereby improving the reliability of the system and the efficiency of SSB signal cycle switching.
