Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a communication method, apparatus, communication equipment, computer-readable storage medium, and computer program product. Background Art

[0002] In the existing 5G (5th Generation Mobile Communication Technology), downlink transmission energy consumption is the main aspect of network energy consumption. When there is no downlink control information or data transmission demand, the transmission period of the synchronization signal can also be increased to reduce the energy consumption overhead caused by broadcasting the synchronization signal. In the carrier aggregation scenario, time synchronization is required between the primary cell and the secondary cell on a regular basis. Specifically, in order to save energy, the secondary cell may not send SSB (Synchronization Signal / PBCH Block). When the terminal device needs to perform time and frequency synchronization with the secondary cell, it can directly obtain the synchronization information of the secondary cell through the primary cell. This multi-carrier downlink energy-saving enhancement technology can effectively reduce the transmission energy consumption caused by the periodic broadcast of SSB in the secondary cell.

[0003] However, the current multi-carrier downlink energy-saving enhancement technology (SSB-less SCell) technology cannot be applied to all carrier aggregation scenarios. For intra-band carrier aggregation (intra-band CA) scenarios, 3GPP Rel-15 (3GPP's first 5G communication standard version) supports the technology of SCell (Secondary Cell) not sending SSB (SSB-without SCell). As long as the UE (User Equipment) supports this function, it can perform time and frequency synchronization with the SCell through the PCell (Primary Cell). However, in the inter-band carrier aggregation (inter-band CA) scenario, since the TA (Time Alignment) error between the primary and secondary cells may be large (especially in non-cooperative communication scenarios), the above method will face greater difficulties, so the application of SSB-less SCell technology in these scenarios also faces greater challenges. Although 3GPP Rel-18 (3GPP's first 5G-A communication standard version) supports the use of SSB-less SCell technology in some inter-band CA scenarios, it is currently limited to FR1 (a 5G frequency band) and collaborative communication scenarios. There are no applicable technical specifications for other carrier aggregation scenarios. In addition, the SCell broadcast SSB signal period setting in the current carrier aggregation scenario is relatively fixed, and the existing network energy-saving solutions do not support flexible broadcast signal period design, which is not conducive to network energy saving. Specifically, the SSB-less SCell solution used in the carrier aggregation scenario usually sets the SSB signal period to a relatively fixed mode, and does not consider flexible adjustment of the SSB signal period during the solution process (such as increasing or decreasing the period based on actual load conditions), which may result in the base station being unable to obtain higher network energy-saving gains. Summary of the invention

[0004] The main purpose of the present application is to provide a communication method, apparatus, communication equipment, computer-readable storage medium and computer program product, aiming to solve the technical problem that the flexibility of the synchronization signal sending period of the secondary cell in the current carrier aggregation scenario is poor, resulting in poor network energy saving gain effect of the base station.

It can be understood that in the technical solution of the present application, the first communication device can be a main cell, the second communication device can be a secondary cell, and the third communication device can be a terminal device. In this way, the first communication device (i.e., the main cell) sends the terminal device request quantity information or the first synchronization signal sending period of the second communication device (i.e., the secondary cell) to the secondary cell, so that the secondary cell can adaptively update the setting of its own synchronization signal sending period, so as to adapt to various inter-band carrier aggregation scenarios and have a wide range of adaptability. It can also enable the secondary cell to send synchronization signals with different periods under different third communication device (terminal device) loads. For example, when the terminal device requests a large amount of information, the terminal device load is high, and the synchronization signal is sent with a relatively small period; when the terminal device requests a small amount of information, the terminal device load is low, and the synchronization signal is sent with a relatively large period, thereby achieving energy saving and improving the flexibility of the system, which can meet user needs in different scenarios and avoid unnecessary energy consumption.

[0144] In order to improve the network energy-saving gain of the base station and overcome the technical defects of the traditional solution, the embodiment of the present application provides a communication method, which is applied to a first communication device. For the convenience of description, the relevant steps of the method will be numbered with S as the beginning. Figure 1 , a communication method applied to a first communication device includes:

[0145] Step S10, receiving first information sent by a third communication device, where the first information is used to determine a second communication device;

[0146] The first communication device, the second communication device and / or the third communication device are all devices with communication functions, and their forms or functions may be different. They can communicate with each other by sending information.

[0147] In a feasible embodiment, the first communication device includes a base station corresponding to a primary cell (i.e., PCell), the second communication device includes a base station corresponding to a secondary cell (i.e., SCell), and the third communication device includes a terminal device (i.e., UE). Among them, the terminal device is an entity on the user side for receiving signals, or sending signals, or receiving signals and sending signals. The terminal device is used to provide one or more of voice services and data connectivity services to users. The terminal device may be a device that includes wireless transceiver functions and can cooperate with network equipment to provide communication services to users. Specifically, the terminal device may refer to user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, terminal, wireless communication equipment, user agent, user device or road side unit (RSU). The terminal device may also be a drone, an Internet of Things (IoT) device, a station (ST) in a WLAN, a cellular phone, a smart phone, a cordless phone, a wireless data card, a tablet computer, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA) device, a laptop computer, a machine type communication (MTC) terminal, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device (also referred to as a wearable smart device), a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a smart city, etc. The terminal device may be a wireless terminal in a smart city, a wireless terminal in a smart home, etc. The terminal device may also be a device to device (D2D) device, such as an electric meter, a water meter, etc.The terminal device may also be a terminal in a 5G system or a terminal in a next-generation communication system, which is not limited in the embodiments of the present application.

[0148] The first communication device may be a base station corresponding to a primary cell, and the primary cell is communicatively connected to at least one second communication device (which may be a base station corresponding to a secondary cell) and / or at least one third communication device (which may be a terminal device).

[0149] In addition, the first communication device and the second communication device may also refer to other network devices corresponding to the primary cell and the secondary cell and having data processing, network communication, and program running functions.

[0150] The third communication device can send relevant information about the second communication device to determine the number of third communication devices loaded by the second communication device. In addition, the first communication device can determine the second communication device corresponding to the third communication device based on the first information sent by the third communication device.

[0151] In a feasible embodiment, the first information may include a measurement result report sent by the third communication device, and / or the first information may include service requirement information sent by the third communication device.

[0152] It should be noted that the communication method of the embodiment of the present application can be applied in the scenario of the 5G communication system, such as Figure 2 As shown, in this scenario, there is a PCell that supports inter-band carrier aggregation function and belongs to a gNB (base station) in the system. An SCell (i.e., the second communication device, secondary cell) of the PCell may save energy through technologies including but not limited to SSB-less, DRX (Discontinuous Reception) / DTX (Discontinuous Transmission). The working frequency band of this SCell is different from that of the PCell, and may belong to the gNB to which the PCell belongs. In this case, the PCell and the SCell can communicate through including but not limited to the gNB internal interface; the SCell may also belong to another gNB (base station) in the system. In this case, the PCell and the SCell can communicate through including but not limited to the Xn interface (interface between base stations). The PCell broadcasts system information within the coverage area, and multiple UEs in the scenario demodulate the system information and establish an RRC (Radio Resource Control Connection) connection with the PCell through the initial access process.

[0153] It should be noted that the technical solution provided in the embodiment of the present application is applicable to a variety of system architectures. The business scenarios described in the embodiment of the present application are intended to more clearly illustrate the technical solution of the embodiment of the present application, and do not constitute a limitation on the technical solution provided in the embodiment of the present application. It is known to those skilled in the art that with the evolution of network architecture and the emergence of new business scenarios, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

[0154] In a 5G communication system, each cell may be a primary cell or a secondary cell, and can realize both the functions of a primary cell and a secondary cell. The execution subject of the embodiment of the present application may be a primary cell or a base station to which the primary cell belongs (when the primary cell and the secondary cell belong to different base stations).

[0155] In a feasible embodiment, before receiving the first information sent by the third communication device, the method further includes: sending synchronization signal configuration information of the second communication device to the third communication device.

[0156] Before step S10, the secondary cell SCell first sends the SSB configuration information (i.e., synchronization signal configuration information, including the current SSB transmission period) of the secondary cell to the base station to which the primary cell PCell belongs through its base station, and then sends the SSB configuration information to the UE device (i.e., the third communication device, the terminal device), which can be in the form of RRC signaling. The information sent by the PCell to the UE device may include one or more of the following information: measurement configuration information of each SCell, SSB configuration of each SCell, including SSB time-frequency resource information, different transmission periods that can be selected when each SCell sends SSB, and the number of SSB selectable periods can be configured by the network, measurement configuration information of the PCell, and indication information indicating that the UE measures the PCell and / or each SCell.

[0157] After receiving the synchronization signal configuration information sent by the PCell, the UE device measures each SCell and PCell based on the configuration information and obtains a corresponding measurement result report. The measurement result report includes measurement parameters used to represent the UE's reference signal for each SCell and PCell (such as the received power reception quality of the reference signal, signal-to-noise ratio, signal strength or energy-to-noise density ratio, etc.). The UE will also send the obtained measurement result report and / or its own service demand information to the main cell. The service demand information represents the UE's business requirements for the SCell and PCell, so as to select a SCell that meets the requirements to provide it with communication services.

[0158] Step S20, sending the third communication device request quantity information and / or the first synchronization signal sending period information corresponding to the second communication device to the second communication device;

[0159] The first communication device transmits the third communication device request quantity information and / or the first synchronization signal sending period corresponding to the second communication device, so that the second communication device can set and update its own synchronization signal sending period.

[0160] The request quantity information or synchronization signal sending period information may be the request quantity information or the synchronization signal sending period itself, or may be other forms of expression corresponding to the request quantity information or the synchronization signal sending period.

[0161] In a feasible embodiment, the first synchronization signal sending period is obtained according to the request quantity information of the third communication device.

[0162] Further, step S10 is supplemented. In a feasible embodiment, before sending the third communication device request quantity information and / or the first synchronization signal sending period information corresponding to the second communication device to the second communication device, the method includes:

[0163] Step S11, obtaining information on the number of second communication devices corresponding to the third communication device and / or the number of third communication devices requested by the second communication device.

[0164] In the embodiment of the present application, the second communication device information corresponding to the third communication device may be obtained, or the third communication device request quantity information corresponding to the second communication device may be obtained, or both may be obtained, which is not limited here.

[0165] It can be understood that the PCell can determine the optimal SCell for each UE as the target SCell of the UE based on the measurement result report and / or UE service demand information sent by the UE, and then count how many UEs have determined each SCell with which it has established communication as the corresponding target SCell, thereby obtaining the UE request quantity information corresponding to each SCell (i.e., the third communication device request quantity information), and the UE request quantity information indicates the UE quantity information that the SCell needs to serve when serving as a secondary cell.

[0166] In a feasible embodiment, the third communication device requests quantity information and / or the first synchronization signal sending cycle information for the second communication device to determine the second synchronization signal sending cycle information, and / or the third communication device requests quantity information and / or the first synchronization signal sending cycle information for the second communication device to set the current synchronization signal sending cycle as the second synchronization signal sending cycle.

[0167] Specifically, the PCell can send the UE request quantity information corresponding to each secondary cell SCell to the corresponding SCell, so that each SCell can adaptively adjust the synchronization signal sending period (SSB sending period) according to the UE request quantity information that it has accumulated and determined. It should be noted that each SCell has established a connection with one or more PCells. For the SCell, it is necessary not only to calculate the number of UE requests from one main cell, but also to combine the number of UE requests from other main cells to calculate the corresponding total number of UE requests. On the other hand, in addition to being a secondary cell, the SCell can also be used as a main cell or a service cell in a non-CA scenario to provide services to UEs. Therefore, when calculating the number of UE requests, it is also necessary to combine the information on the number of UEs served when acting as a PCell and a service cell.

[0168] In addition, in addition to sending the UE request quantity information of the SCell to the SCell, the PCell can also convert the UE request quantity into the corresponding first synchronization signal sending period through the PCell, and initially complete the process of determining the SSB sending period for the SCell based on the UE request quantity information, and then send the first SSB sending period to the SCell.

[0169] That is, the UE request quantity information or the first SSB sending period sent by the PCell is used by the SCell to determine the final second synchronization signal sending period (ie, the second SSB sending period) in combination with the first SSB sending period from other PCells.

[0170] Whether the SCell determines the second SSB transmission period by calculating the total number of UE requests, or the PCell determines the first SSB transmission period based on the obtained UE request number information corresponding to the SCell, it can be done according to the rule that the number of UE requests is inversely proportional to the cycle length. This is because the more UE requests, the higher the SCell load, and the more frequent SSB transmission is required, so a shorter SSB transmission period is required; and when the number of UE requests is less, the SCell load is lower, and the demand for SSB transmission is not high, so the SSB transmission period can be appropriately increased, thereby reducing energy consumption and improving the network energy saving gain effect of the base station.

[0171] It should be noted that when the base stations to which the PCell and SCell belong are different, the aforementioned execution entities "PCell" and "SCell" can be replaced by "the base station to which the PCell belongs" and "the base station to which the SCell belongs" respectively.

[0172] In a feasible embodiment, after step S20, the method may further include:

[0173] Step S30, receiving synchronization signal configuration information sent by the second communication device,

[0174] And / or, step S40, sending synchronization signal configuration information to at least one third communication device.

[0175] The second communication device sets the current synchronization signal sending period as the second synchronization signal sending period. In order to achieve synchronization of the synchronization signal sending period, the second communication device then adds the current synchronization signal sending period to the synchronization signal configuration information to achieve signal synchronization.

[0176] In addition, the first communication device may also send the received synchronization signal configuration information to the third communication device to achieve information synchronization at the third communication device, which may serve as a data basis for the third communication device to select the corresponding second communication device.

[0177] In a feasible embodiment, the step of sending the third communication device request quantity information of the second communication device or the first synchronization signal sending period information corresponding to the third communication device request quantity information to the second communication device, step S20 may include:

[0178] Step S21, if the number of requests from the third communication device is less than a preset request number threshold, sending the information of the number of requests from the third communication device to the second communication device; and / or,

[0179] Step S22: If the number of requests from the third communication device is greater than or equal to a preset request number threshold, the first synchronization signal sending period information is sent to the second communication device.

[0180] An embodiment of the present application provides a method for a main cell PCell to determine whether to send UE request quantity information or a first SSB sending period according to the UE request quantity information of a secondary cell, which can be specifically determined based on a preset request quantity threshold.

[0181] Exemplarily, when the PCell determines that the number of UE requests of the SCell is less than the preset request number threshold, it means that the number of UE requests is small, and the information overhead sent by the PCell to the SCell is small, and the UE request number information can be directly sent to the SCell. When the number of UE requests of the SCell is greater than or equal to the preset request number threshold, it means that the number of UE requests is large, and the information overhead sent is large. Since the number of bits of the SSB transmission period is less than the number of bits required to send the UE request number, in order to save information overhead and reduce the bit error rate, the UE request number is converted into the corresponding first SSB transmission period before being sent to the SCell.

[0182] In a feasible embodiment, before the step of sending the first synchronization signal sending period information to the second communication device, the method may further include:

[0183] The first synchronization signal sending period of the second communication device is obtained according to the relationship between the third communication device request quantity information and at least one threshold.

[0184] The relationship between the third communication device request quantity information and at least one threshold value includes a size relationship.

[0185] Further, when determining the relationship between the number of requests from the third communication device and the threshold, the corresponding threshold may be determined according to the current synchronization signal sending cycle, that is, different thresholds may be determined according to different synchronization signal sending cycles.

[0186] Among them, the current synchronization signal sending period of the second communication device is one of a plurality of preset periods, different preset periods correspond to different quantity thresholds, and the relationship between the communication device request quantity information and the quantity threshold can be a size relationship. For example, when the third communication device requests quantity information greater than the quantity threshold, it corresponds to a first synchronization signal sending period; when the third communication device requests quantity information less than the quantity threshold, it corresponds to another synchronization signal sending period.

[0187] If the PCell needs to send the first SSB transmission period corresponding to its UE request quantity information to the SCell, it is necessary to first convert it into the corresponding period duration according to the UE request quantity information. Specifically, one or more pre-set quantity thresholds can be used to determine the quantity information value range of the UE request quantity information according to the relationship between the third device request quantity information and the digital threshold, thereby determining the corresponding first SSB transmission period.

[0188] In this case, the SCell can send SSB based on one of a plurality of optional SSB sending periods. The aforementioned quantity thresholds constitute a value range of multiple UE request quantity information. The larger the corresponding value range, the shorter the corresponding SSB period. Thus, the first SSB sending period corresponding to the SCell is obtained, thereby realizing adaptive and flexible adjustment of the SSB sending period.

[0189] It should be noted that sending the first SSB sending period by PCell to SCell not only includes directly sending the SSB sending period, but may also include implicit indication methods, such as predefining several SCell operating states corresponding to different SSB sending periods and indicating the SCell operating states, or associating the SSB sending period adjustment with other SCell configuration processes by default.

[0190] In a feasible embodiment, the step of obtaining the second communication device corresponding to the third communication device may include:

[0191] Determine the second communication device corresponding to the third communication device according to the measurement result report and / or the service requirement information of the third communication device.

[0192] Optionally, the matching degree between each second communication device and the third communication device may be evaluated according to the measurement result report and / or the service requirement information of the third communication device, and then the second communication device with the highest matching degree may be selected as the second communication device corresponding to the third communication device.

[0193] The measurement result report includes at least the received power, received quality and / or signal-to-noise ratio corresponding to the secondary cell reference signal and the primary cell reference signal, respectively. The embodiment of the present application provides a method for selecting the corresponding target Scell ​​by the PCell according to the measurement result report sent by the UE device. Specifically, the measurement result report includes the parameters such as the received power, received quality and / or signal-to-noise ratio of the PCell and SCell measured by the UE device, which can be used to select the SCell with the best parameters. In the process of evaluating the SCell, the weight of each parameter can be set according to actual needs, and there is no restriction here.

[0194] The service requirement information of the UE device reflects the requirements of the UE device for the PCell and SCell. Based on this information, the PCell can select the SCell that best meets the requirements of the UE device, that is, the SCell with the highest matching degree, from among the SCells.

[0195] For example, in the process of applying the communication method of the embodiment of the present application, a feasible communication process and / or data processing process between devices is as follows: Figure 3As shown, the specific steps may include: Step 1, SCell sends SSB configuration information to PCell; Step 2, PCell sends SSB configuration (such as SSB sending period configuration) and measurement configuration of each SCell to UE; Step 3, UE measures SCell and / or PCell based on the configuration information; Step 4, UE sends measurement result report and / or UE service demand information to PCell; Step 5, PCell determines the target SCell based on the measurement result and / or UE service demand information, and counts the "UE request number" corresponding to each target SCell; Step 6, PCell sends the "UE request number" to SCell; Step 7, SCell determines the updated SSB sending period (i.e., the second SSB sending period) based on the "UE request number" of all associated PCells, the number of user requests served by the service cell as a non-SCell, etc.; Step 8, SCell informs PCell of the SSB sending period; Step 9, PCell informs UE of the SSB sending period.

[0196] For example, in the process of applying the communication method of the embodiment of the present application, another feasible communication process and / or data processing process between the devices is as follows: Figure 4 As shown, the specific steps include: Step 1, SCell sends SSB configuration information to PCell; Step 2, PCell sends SSB configuration (such as SSB sending period configuration) and measurement configuration of each SCell to UE; Step 3, UE measures SCell and / or PCell based on the configuration information; Step 4, UE sends measurement result report and / or UE service demand information to PCell; Step 5, PCell determines the target SCell based on the measurement result and / or UE service demand information, counts the "UE request number" corresponding to each target SCell, and determines the "target SSB sending period" (i.e., the first SSB sending period) of the target SCell; Step 6, PCell sends the "target SSB sending period" to the target SCell; Step 7, SCell determines the updated SSB sending period (i.e., the second SSB sending period) based on the "target SSB sending period" of all associated SCells, the number of user requests served by the service cell as a non-SCell, etc.; Step 8, SCell informs PCell of the SSB sending period; Step 9, PCell informs UE of the SSB sending period.

[0197] The embodiment of the present application is equivalent to providing a SSB transmission period setting strategy based on user request quantity information. This strategy allows the SCell to transmit SSB with a larger period when the user request quantity information is small, and to transmit SSB with a smaller period when the user request quantity information is large, so as to achieve the purpose of saving resources while ensuring the quality of service as much as possible. Moreover, in this strategy, the SSB transmission period quantity information of the SCell can be determined by the network configuration, so that the network can meet the needs of different scenarios in a more flexible way.

[0198] The present application also provides a communication method applied to a second communication device, wherein the second communication device is in communication connection with at least one first communication device and / or at least one third communication device. For the sake of convenience, the description of the steps of the method will use numbers starting with C. The communication method includes:

[0199] Step C10, receiving the third communication device request quantity information sent by the first communication device;

[0200] Or, step C20, receiving first synchronization signal sending period information corresponding to the third communication device request quantity information sent by the first communication device;

[0201] In a feasible embodiment, the first communication device includes a base station corresponding to a primary cell (ie, PCell), the second communication device includes a base station corresponding to a secondary cell (ie, SCell), and the third communication device includes a terminal device (ie, UE).

[0202] The embodiment of the present application provides a communication method with a secondary cell SCell as the execution subject, which corresponds to the aforementioned communication method with a primary cell PCell as the execution subject. Specifically, the secondary cell SCell first sends the SSB configuration information of the secondary cell (i.e., synchronization signal configuration information, including the current SSB transmission period) to the base station to which the primary cell PCell belongs through its base station, and then sends the SSB configuration information to the UE device, which can be sent in the form of RRC signaling. The information sent by the PCell to the UE device may include one or more of the following information: measurement configuration information of each SCell, SSB configuration information of each SCell, including SSB time-frequency resource information, different transmission periods that can be selected when each SCell sends SSB, and the number of selectable periods of the SSB can be configured by the network, and also includes measurement configuration information of the PCell, indication information indicating the UE to measure the PCell and / or each SCell, etc.

[0203] After receiving the synchronization signal configuration information sent by the PCell, the UE measures each SCell and PCell based on the configuration information and obtains a corresponding measurement result report. The measurement result report includes measurement parameters used to represent the UE's reference signal for each SCell and PCell (for example, the received power, received quality, signal-to-noise ratio, signal strength or energy-to-noise density ratio of the reference signal, etc.). The UE will also send the obtained measurement result report and / or its own service demand information to the main cell. The service demand information represents the UE's demand for the corresponding SCell and PCell, so as to select a SCell that meets the requirements to provide it with communication services.

[0204] Specifically, after receiving the measurement result report and / or UE service requirement information sent by the UE device, the PCell will select the corresponding SCell for the UE device, and then count the UE request quantity information corresponding to each SCell and send it to the SCell, or the PCell will first determine the first synchronization signal sending period (first SSB sending period) corresponding to each SCell based on the UE request quantity information of each SCell and send it to the SCell.

[0205] In a feasible embodiment, after receiving the third communication device request quantity information sent by the first communication device and / or receiving the first synchronization signal sending period sent by the first communication device, the method further includes:

[0206] Step C30, determining a second synchronization signal sending period,

[0207] And / or, step C40, setting the synchronization signal sending period to a second synchronization signal sending period.

[0208] In an embodiment of the present application, after the SCell receives the UE request quantity information or the first SSB sending period sent by the PCell, it can adaptively adjust the current SSB sending period according to the UE request quantity information or the first SSB sending period sent by the PCell and set it to the second synchronization signal sending period (second SSB sending period).

[0209] Specifically, SCell can adaptively adjust the synchronization signal sending period (SSB sending period) according to its own accumulated UE request quantity information. It should be noted that SCell has established connections with one or more PCells respectively. For SCell, it is necessary not only to calculate the UE request quantity information from one main cell, but also to combine the UE request quantity information from other main cells to calculate the corresponding total UE request quantity information. On the other hand, in addition to being a secondary cell, SCell can also be used as a main cell or a service cell in a non-CA scenario to provide services to UEs. Therefore, when calculating the UE request quantity information, it is also necessary to combine the UE quantity information served when it is a PCell and a service cell.

[0210] On the other hand, the PCell can also be used to first convert the UE request quantity into the corresponding first synchronization signal sending period, and preliminarily complete the process of determining the SSB sending period based on the UE request quantity for the SCell, and then send the first SSB sending period to the SCell. The SCell can determine the final second synchronization signal sending period (i.e., the second SSB sending period) in combination with the first SSB sending period from other PCells.

[0211] Whether the SCell determines the second SSB transmission period by calculating the total number of UE requests, or the PCell determines the first SSB transmission period based on the number of UE requests corresponding to the SCell, it can be done according to the rule that the number of UE requests is inversely proportional to the cycle length. This is because the more UE requests, the higher the SCell load, and the more frequent SSB transmission is required, so a shorter SSB transmission period is required; and when the number of UE requests is less, the SCell load is lower, and the need for SSB transmission is not so high, so the SSB transmission period can be appropriately increased, thereby reducing energy consumption and improving the network energy saving gain effect of the base station.

[0212] Further, in a feasible embodiment, after the step of setting the current synchronization signal sending period as the second synchronization signal sending period, the method further includes:

[0213] Step C50: Send the set second synchronization signal sending period information to the first communication device and / or the third communication device.

[0214] In addition to sending the set second SSB transmission period to the PCell and UE devices, without the need to reset or refuse to reset the SSB transmission period, the current SSB transmission period can also be sent to the PCell and UE devices to synchronize the SSB period.

[0215] Further, step C30 is supplemented with an explanation. In a feasible embodiment, the step of determining the second synchronization signal sending period includes:

[0216] Step C31, obtaining the total number of requests from the third communication device;

[0217] Among them, the total number information requested by the third communication device is one of the core parameters for determining the second synchronization signal sending period.

[0218] Optionally, step C31 may include: obtaining total number information of requests from third communication devices according to the number information of requests from third communication devices and / or the number information of third communication devices respectively corresponding to the second communication device when implementing the primary cell function and the serving cell function;

[0219] Furthermore, step C31 may also include:

[0220] Step C311, counting the sum of the third communication device request quantity information corresponding to the second communication devices sent by each first communication device to obtain the first device quantity information;

[0221] And / or, step C312, counting the quantity information of the third communication devices corresponding to the second communication device when the second communication device implements the primary cell function, to obtain the second device quantity information;

[0222] And / or, step C313, counting the number information of third communication devices corresponding to the second communication device when implementing the serving cell function, to obtain the number information of third devices;

[0223] Step C314, obtaining the total number of third communication device requests corresponding to the second communication device according to at least one of the first device number information, the second device number information, and the third device number information.

[0224] In the process of calculating the total number of UE device requests served by the SCell, it is necessary to count the number of UE devices from three aspects. First, when the cell of the SCell is used as an SCell in the CA scenario, the sum of the number of UE requests counted by all associated PCells is obtained to obtain the first device quantity information, and the data comes from the PCells associated therewith; second, when the cell of the SCell is used as a PCell in the CA scenario, the sum of the number of UE requests counted is obtained to obtain the second device quantity information, and the data can be obtained by itself; third, in the non-CA scenario, when the Scell ​​is used as a serving cell, the UE request number information is counted, and the data is obtained from itself.

[0225] Finally, the sum of the UE request quantity information corresponding to the three situations is calculated to obtain the total number of UE request devices to be served by the SCell, which is used to characterize the load condition of the SCell.

[0226] To supplement step C30, step C32 obtains a second synchronization signal sending period according to a (size) relationship between the total number of third communication device request information and at least one threshold value.

[0227] Furthermore, different current synchronization signal periods may correspond to different thresholds. The current synchronization signal sending period of the second communication device is one of a plurality of preset periods, and different preset periods correspond to different quantity thresholds.

[0228] An embodiment of the present application provides a process for determining the second SSB sending period by comparing the total number of UE requests determined based on the number of UE requests sent by each PCell associated with it and the number of UE requests of itself when it is a non-SCell with a quantity threshold.

[0229] It should be noted that when the current synchronization signal transmission period is in different value conditions, the quantity threshold used for comparison is different. For example, for SCell, there are a variety of optional SSB transmission periods. When in different SSB transmission periods, different settings of rising or falling need to be updated, so different quantity thresholds can be set respectively, so that the SSB transmission period of SCell can be adaptively and flexibly set according to the current period situation. In addition, the larger the total number of UE requests, the shorter the corresponding second SSB transmission period.

[0230] Further, step C32 is supplemented with an explanation that obtaining the second synchronization signal sending period according to the relationship between the total number of requests from the third communication device and at least one threshold value includes:

[0231] Step C321: if the synchronization signal sending period of the second communication device is the first preset period, and,

[0232] If the total number of requests from the third communication device is less than or equal to the first threshold and greater than or equal to the second threshold, the second synchronization signal sending period is the second preset period; and / or,

[0233] If the total number of requests from the third communication device is less than or equal to the second threshold, the second synchronization signal sending period is the third preset period;

[0234] The second communication device may include at least three different preset periods, and the second communication device includes at least a first preset period. Various preset periods are optional periods configured on the communication device and can be adaptively set according to actual conditions.

[0235] When the SCell has three optional SSB transmission periods, three different SSB transmission periods may be included, namely, a first preset period T1, a second preset period T2, and a third preset period T3, and T1, T2, and T3 increase sequentially.

[0236] Specifically, if the total number of UE requests is less than the first threshold and greater than or equal to the second threshold, the second SSB sending period of the SCell is determined as the second preset period T2; if the total number of UE requests is less than the second threshold, the second SSB sending period of the SCell is determined as the third preset period T3, where the first threshold and the second threshold are quantity thresholds.

[0237] like Figure 5 As shown, if the current SSB sending period of the SCell is the first preset period T1, that is, the shortest period, the second SSB sending period can be determined according to the first threshold ThreshUE1_d and the second threshold ThreshUE2_d.

[0238] Supplementary explanation is given to step C32. In step C322, if the synchronization signal sending period of the second communication device is the second preset period, and,

[0239] If the total number of requests from the third communication device is greater than or equal to the third threshold, the second synchronization signal sending period is the first preset period; and / or,

[0240] If the total number of requests from the third communication device is less than or equal to the second threshold, the second synchronization signal sending period is a third preset period, wherein the third threshold is greater than the second threshold;

[0241] The second communication device further includes a second preset period, and the second preset period is greater than the first preset period.

[0242] like Figure 5 As shown, if the current SSB sending period of the SCell is T1, that is, the length is in the middle period, the second SSB sending period can be determined according to the third threshold ThreshUE1_u and the second threshold ThreshUE2_d, where the third threshold is the quantity threshold.

[0243] Specifically, if the total number of UE requests is greater than the first threshold, the second SSB sending period of the SCell is determined to be T1; if the total number of UE requests is less than the second threshold, the second SSB sending period of the SCell is determined to be T3.

[0244] Supplementary explanation is given to step C32. In step C323, if the synchronization signal sending period of the second communication device is the third preset period, and,

[0245] If the total number of requests from the third communication device is greater than or equal to the third threshold, the second synchronization signal sending period is the first preset period; and / or,

[0246] If the total number of requests from the third communication device is greater than or equal to the fourth threshold and less than or equal to the third threshold, the second synchronization signal sending period is the second preset period.

[0247] The second communication device further includes a third preset period, and the third preset period is greater than the second preset period.

[0248] like Figure 5 As shown, if the current SSB sending period of the SCell is T3, that is, the longest period, the second SSB sending period can be determined according to the third threshold ThreshUE1_u and the fourth threshold ThreshUE2_u, and the fourth threshold is the quantity threshold.

[0249] Specifically, if the total number of information requested by the UE is greater than or equal to the third threshold, the second SSB sending period is determined to be T1; if the total number of information requested by the UE is greater than or equal to the fourth threshold and less than the third threshold, the second SSB sending period is determined to be T2.

[0250] Exemplarily, the magnitude relationship of each quantity threshold may be ThreshUE1_u>ThreshUE1_d>ThreshUE2_u>ThreshUE2_d. Figure 5 The left downward arrow in the figure indicates that the sending cycle increases, and the right upward arrow indicates that the sending cycle decreases.

[0251] The SCell communication method provided in the embodiment of the present application is applied to the number of UE requests, so that the SCell can more flexibly and efficiently adjust the SSB transmission period while meeting user needs. By comprehensively considering the number of UE requirements for all PCell connections associated with the cell as an SCell and the number of UE requirements when it is a service cell other than the SCell, the demand for all UEs in the same SCell can be more effectively evaluated, so that the operating status of the SCell can be determined more reasonably, so that the frequency of the SCell sending SSB matches the UE demand in real time, thereby effectively saving energy consumption in the network communication process.

[0252] In another feasible embodiment, obtaining the second synchronization signal sending period according to the relationship between the total number of requests of the third communication device and at least one threshold value may also include:

[0253] If the total number of requests from the third communication device is greater than or equal to the fifth threshold, the second synchronization signal sending period is the first preset period; and / or,

[0254] If the total number of requests from the third communication device is greater than or equal to the sixth threshold and less than or equal to the fifth threshold, the second synchronization signal sending period is the second preset period; and / or,

[0255] If the total number of requests from the third communication device is less than or equal to the sixth threshold, the second synchronization signal sending period is the third preset period.

[0256] Compared with the method for determining the second synchronization signal transmission period in the previous embodiment, the present embodiment does not consider the "ping-pong effect", that is, does not consider the current synchronization signal transmission period, and directly determines the value of the second synchronization signal transmission period according to a fixed threshold. Its advantage is that the method for determining the period is simpler and the amount of calculation is less. The fifth threshold and the sixth threshold are both quantity thresholds.

[0257] In another feasible embodiment, the step of determining the second synchronization signal sending period may include:

[0258] Supplementary explanation is given to step C30. In step C33, if the received first synchronization signal transmission period information includes a first preset period, the second synchronization signal transmission period is set to the first preset period, wherein the first preset period is less than the first preset period threshold;

[0259] Among them, the first preset cycle threshold is a preset threshold for screening the first preset cycle, and the first preset cycle can be understood as one or more of the shortest optional preset cycles in the second communication device, indicating the most frequent cycle transmission requirements, and the first preset cycle is less than the first preset cycle threshold. When the first preset cycle is less than the first preset cycle threshold, the second communication device is required to send a cycle synchronization signal at the highest cycle synchronization signal transmission frequency, so the second synchronization signal transmission period is directly set to the first preset period to meet the communication requirements.

[0260] An embodiment of the present application also provides a method in which, when a PCell sends a first SSB sending period to a SCell, the SCell determines a second SSB sending period that needs to be set based on the first SSB sending period.

[0261] First, if the first SSB sending period received by the SCell from each PCell includes the first preset period T1 (the shortest period), it means that the SCell's UE request quantity information about the PCell has reached the highest requirement. At this time, there is no need to consider the values ​​of other first SSB sending periods. The second SSB sending period is directly determined as the first preset period T1 to meet high load requirements and improve service quality.

[0262] And / or, step C34, if the received first synchronization signal sending period information does not include the first preset period, then,

[0263] Obtaining the total number of requests of the third communication devices according to the number information of the third communication devices and / or the sum of the number of requests of the third communication devices respectively corresponding to the second communication device when implementing the primary cell function and the serving cell function;

[0264] A second synchronization signal sending period is obtained according to a relationship between the total number information of the third communication device requests and at least one threshold.

[0265] If the first SSB transmission period received by the SCell from each PCell does not include the first preset period, the conversion between the period and the requested quantity is performed according to the specific value of the first SSB transmission period sent by each PCell, and the SCell determines the second SSB transmission period according to the number of devices requested by the UE. It should be noted that this situation includes the situation where the first SSB transmission period from each PCell includes the second preset period and the third preset period, only includes the second preset period and / or only includes the third preset period.

[0266] In the process of converting the first SSB transmission period into the number of UE requests, it is necessary to combine the various quantity thresholds used in the process of determining the first SSB transmission period. Moreover, the shorter the first SSB transmission period, the greater the number of UE device requests obtained by conversion. In addition, the process of PCell determining the first SSB transmission period according to the number of UE requests of each SCell can refer to the process of the aforementioned steps S311 to S313, and multiple quantity thresholds need to be applied.

[0267] Optionally, the total number of third communication device requests may be obtained by counting the number of third communication devices corresponding to the second communication device when the second communication device implements the primary cell function and the serving cell function, respectively, and summing the number of third communication devices obtained by the conversion;

[0268] The second synchronization signal sending period is determined based on comparing the total number of requests from the third communication devices with at least one threshold.

[0269] In addition to counting the sum of the UE request quantity information sent by each PCell associated with the SCell, it is also necessary to count the UE request quantity information obtained when the cell is used as a PCell in a CA scenario, and / or the user request quantity information obtained when the cell is used as a service cell in a non-CA scenario, and then obtain the total UE request quantity information corresponding to the SCell.

[0270] Similarly, after obtaining the total number of UE requests, the second SSB sending period corresponding to the total number of UE requests is determined as the final SSB sending period to be set in the same manner as steps C321 to C323 in the aforementioned embodiment, which will not be repeated here.

[0271] Exemplarily, step C34 is supplemented with an explanation that before the step of obtaining the total number of third communication device request information according to the number information of the third communication devices and / or the number information of the third communication devices respectively corresponding to the second communication device when implementing the primary cell function and implementing the serving cell function, the step may also include:

[0272] Step C341, when the first synchronization signal transmission period transmitted by the first communication device is the third preset period, the third communication device requests that the quantity information be a quantity information less than the second threshold value; and / or,

[0273] Step C342, when the first synchronization signal sending period sent by the first communication device is the second preset period, the third communication device requests quantity information to be a quantity information greater than the second threshold, wherein the second preset period is greater than the first preset period, and the third preset period is greater than the second preset period.

[0274] Exemplarily, when the first synchronization signal sending period sent by the first communication device is a third preset period, the third communication device request quantity information is determined to be quantity information less than a second threshold;

[0275] When the first SSB sending period sent by PCell is the third preset period T3 (ie, the longest period), it is converted into a UE request quantity that is less than the second threshold ThreshUE2_d.

[0276] For example, the UE request quantity information obtained by conversion may be (ThreshUE2_d-1) / 2, or may be any integer value between 0 and ThreshUE2_d.

[0277] When the first synchronization signal sending period sent by the first communication device is the second preset period, the third communication device request quantity information is determined to be quantity information greater than the second threshold.

[0278] When the first SSB sending period sent by PCell is the second preset period T2, it is converted into UE request quantity information greater than the second threshold ThreshUE2_d.

[0279] For example, the UE request quantity information obtained by conversion may be ThreshUE2_d+1.

[0280] The communication method provided in the embodiment of the present application uses SCell to determine the SSB period based on the "target SSB transmission period" or "UE request number" sent by all PCells, the UE demand number collected when serving as a non-SCell service cell, and other information, so that SCell can more efficiently adjust the SSB transmission period. In the scheme where PCell sends UE request number information to SCell, since SCell directly determines the updated operating status based on the "UE request number", the operating status determination accuracy of SCell is relatively high. In the scheme where PCell sends the first SSB transmission period to SCell, the information overhead sent by PCell to SCell is relatively small. This is because the number of bits required to send the SSB transmission period is less than the number of bits required to directly send the UE request number.

[0281] In another feasible embodiment, step C32 is supplemented, the second communication device includes at least two different preset cycles, and the step of obtaining the second synchronization signal sending cycle according to the size relationship between the total number of information requested by the third communication device and at least one number threshold corresponding to the current synchronization sending cycle may include:

[0282] Step C324: if the synchronization signal sending period of the second communication device is the fourth preset period,

[0283] If the total number of requests from the third communication device is less than or equal to the seventh threshold, the second synchronization signal sending period is the fifth preset period; and / or,

[0284] Step C325: if the synchronization signal sending period of the second communication device is the fifth preset period,

[0285] If the total number of requests from the third communication device is greater than or equal to the eighth threshold, the second synchronization signal sending period is the fourth preset period;

[0286] The fifth preset period is greater than the fourth preset period.

[0287] Optionally, the above steps can be understood as: when the synchronization signal sending period of the second communication device is the fourth preset period, the total number of requests of the third communication device is compared with the seventh threshold; and / or, when the synchronization signal sending period of the second communication device is the fifth preset period, the total number of requests of the third communication device can be compared with the eighth threshold. Further, if the total number of requests of the third communication device is less than the seventh threshold, the second synchronization signal sending period is set to the fifth preset period; if the total number of requests of the third communication device is greater than or equal to the eighth threshold, the second synchronization signal sending period is set to the fourth preset period. Among them, the seventh threshold and the eighth threshold are both quantity thresholds.

[0288] Exemplarily, the seventh threshold value may be equal to the eighth threshold value, both being ThreshUE1_d. When the total number of UE requests is less than ThreshUE1_d, the second SSB transmission period should be the fifth preset period T5 (the longest period). Therefore, when the current SSB transmission period is T4, the second SSB transmission period is determined to be T5. If the current SSB transmission period is already T5, it remains unchanged. When the total number of UE requests is greater than or equal to ThreshUE1_d, the second SSB transmission period should be the first preset period T4 (the shortest period). Therefore, when the current SSB transmission period is T5, the second SSB transmission period is determined to be T4. If the current SSB transmission period is already T4, it remains unchanged.

[0289] The present application also provides a communication method applied to a second communication device, wherein the second communication device is in communication connection with at least one first communication device and / or at least one third communication device. For the sake of convenience, the description of the steps of the method will use numbers starting with D. The method includes:

[0290] Step D10, obtaining the requested quantity information of the third communication device;

[0291] The method for obtaining the request quantity information of the third communication device may be determined according to the received service demand information sent by the third communication device.

[0292] Step D20, determining the second synchronization signal sending period according to the request quantity information of the third communication device, and / or setting the current synchronization signal sending period as the second synchronization signal sending period.

[0293] Optionally, before step D10, the method may further include the step of sending current synchronization signal configuration information to the first communication device.

[0294] An embodiment of the present application provides a communication method focusing on the secondary cell SCell and the terminal device UE. Compared with the communication method mentioned in the aforementioned embodiment, the step of selecting the target SCell according to the UE's measurement results and / or the UE service demand information is completed by the UE itself, not the PCell. After the UE determines the target SCell, the UE service demand information is directly sent to the SCell, and then the SCell counts the UE request quantity information when the SCell function is implemented and / or the non-SCell function (including CA scenarios and non-CA scenarios), so as to determine the total number of UE requests, and determine and set the final second SSB sending period based on the total number of UE requests and the preset number threshold, and finally inform the PCell and UE of the latest SSB sending period.

[0295] Among them, the steps of determining the final second SSB sending cycle based on the total number of UE request information and the preset number threshold can refer to the aforementioned steps C321 to C323 and will not be repeated here.

[0296] Exemplarily, the communication process and / or processing process between the devices in the embodiment of the present application is as follows: Figure 6 The specific steps include: Step 1, SCell sends SSB configuration information to PCell; Step 2, PCell sends SSB configuration (such as SSB sending period configuration), measurement configuration, etc. of each SCell to UE; Step 3, UE measures SCell and / or PCell based on the configuration information to determine the target SCell; Step 4, UE service demand information is sent to the target SCell; Step 5, based on all "UE request quantities", the updated SSB sending period is determined; Step 6, PCell is informed of the SSB sending period; Step 7, UE is informed of the SSB sending period.

[0297] The present application also provides a method for setting a synchronization signal period applied to a third communication device, wherein the third communication device is in communication connection with at least one first communication device and / or at least one second communication device. For the sake of convenience, the description of the steps of the method will use numbers starting with E. Figure 7 , the communication method comprises:

[0298] Step E10, measuring at least one cell and obtaining a corresponding measurement result report;

[0299] Step E20: Send the measurement result report and / or service requirement information to the first communication device.

[0300] In a feasible embodiment, the first communication device includes a base station corresponding to a primary cell (ie, PCell), the second communication device includes a base station corresponding to a secondary cell (ie, SCell), and the third communication device includes a terminal device (ie, UE).

[0301] In a feasible embodiment, before measuring at least one cell and obtaining a corresponding measurement result report, the method may further include:

[0302] Receive synchronization signal configuration information sent by the first communication device.

[0303] In addition to receiving the SSB configuration signal sent by the PCell, the UE can also receive one or more of the following information notified by the PCell: measurement configuration information of each SCell, SSB configuration of each SCell, including SSB time-frequency resource information, different selectable sending periods when each SCell sends SSB, and the number of selectable SSB periods can be configured by the network, measurement configuration information of the PCell, and indication information instructing the UE to measure the PCell and / or each SCell.

[0304] Furthermore, an embodiment of the present application also provides a communication method applied to a terminal device. After receiving the synchronization signal configuration information sent by the PCell, the UE measures each SCell and PCell based on the configuration information to obtain a corresponding measurement result report. The measurement result report includes measurement parameters for indicating the reference signal of each SCell and PCell of the UE (for example, the received power, received quality, signal-to-noise ratio, signal strength or energy-to-noise density ratio of the reference signal, etc.). The UE will also send the obtained measurement result report and / or its own service demand information to the PCell. The service demand information indicates the UE's demand for the corresponding SCell and PCell, so as to select an SCell that meets the requirements to provide it with communication services.

[0305] After the UE sends the measurement result report and / or service requirement information to the PCell, the PCell can determine the optimal SCell for each UE as the target SCell of the UE based on the UE's measurement results and / or UE service requirement information, and then count how many UEs have determined each SCell with which it has established communication as the corresponding target SCell, thereby obtaining the UE request quantity information corresponding to each SCell. The UE request quantity information indicates the number of UEs that the SCell needs to serve when it acts as a secondary cell.

[0306] The UE request quantity information corresponding to each secondary cell SCell is sent to the corresponding SCell, so that each SCell can adaptively adjust the synchronization signal sending period (SSB sending period) according to its own accumulated UE request quantity information. It should be noted that each SCell has established a connection with one or more PCells. For the SCell, it is necessary not only to calculate the UE request quantity information from one main cell, but also to combine the UE request quantity information from other main cells to calculate the corresponding total UE request quantity information. On the other hand, in addition to being a secondary cell, the SCell can also be used as a main cell or a service cell in a non-CA scenario to provide services to the UE. Therefore, when calculating the UE request quantity information, it is also necessary to combine the UE quantity information served when it is a PCell and a service cell.

[0307] On the other hand, in addition to sending the UE request quantity information of the SCell to the SCell, the UE request quantity information can also be converted into the corresponding first synchronization signal sending period through the PCell, and the process of determining the SSB sending period according to the UE request quantity information is preliminarily completed for the SCell, and then the first SSB sending period is sent to the SCell for the SCell to combine the first SSB sending period from other PCells to determine the final second synchronization signal sending period (i.e., the second SSB sending period).

[0308] Further, step E10 is supplemented. In a feasible embodiment, the step of measuring at least one cell and obtaining a corresponding measurement result report may include:

[0309] Step E11, measuring a reference signal of the second communication device to obtain a measurement result of the second communication device;

[0310] Step E12: If the measurement result of the second communication device meets the first condition, the measurement result of the second communication device is included in the measurement result report.

[0311] Optionally, after determining whether the measurement result of the second communication device meets the first condition, if so, the measurement result of the second communication device is recorded in a measurement result report.

[0312] The UE can measure each SCell and PCell based on the synchronization signal configuration information to obtain a measurement result. Specifically, the UE can perform measurements based on a variety of test events, including but not limited to a first measurement event. The first measurement event may include the UE measuring a reference signal of the SCell.

[0313] Further, step E12 is supplemented. After the step of obtaining the measurement result of the second communication device, the method further includes:

[0314] Step E121: If the measurement result is greater than a preset ninth threshold or the sum of the measurement result and the first hysteresis parameter is greater than the ninth threshold, the measurement result of the second communication device meets the first condition.

[0315] Optionally, first determine whether the measurement result is greater than a preset ninth threshold (a custom threshold for the measurement result), or determine whether the sum of the measurement result and the first lag parameter is greater than the ninth threshold; if the measurement result is greater than the preset ninth threshold or the sum of the measurement result and the first lag parameter is greater than the ninth threshold, then determine that the measurement result of the second communication device meets the first condition.

[0316] Specifically, if Ms+Hys1>Thresh1_meas, or Ms>Thresh1_meas, it is determined that the first condition is met, and the measurement related information is recorded in the test report. Among them, Ms is the measurement result of SCell (such as RSRP (Reference Signal Receiving Power) of the reference signal, indicating the average value of the signal power received on all resource elements carrying the reference signal in a symbol), RSRQ (Reference Signal Receiving Quality, indicating LTE reference signal reception quality), RSSI (Received Signal Strength Indicator, indicating received signal strength indication), SINR (Signal to Interference plus Noise Ratio, signal to interference plus noise ratio), RSCPEcN0 (Received Signal Code Power, indicating the received power on a codeword, EcNo indicates the ratio of energy on the pilot channel to total interference), Hys1 is the first hysteresis parameter, and Thresh_meas1 is the first threshold of the measurement result (i.e., the ninth threshold).

[0317] Further, to supplement step E10, the step of measuring at least one cell and obtaining a corresponding measurement result report may include:

[0318] Step E13, measuring a reference signal of the first communication device to obtain a measurement result of the first communication device;

[0319] Step E14: If the measurement result of the first communication device meets the second condition, the measurement result of the first communication device is included in the measurement result report.

[0320] Optionally, after determining whether the measurement result of the first communication device meets the second condition, if so, the measurement result of the first communication device is recorded in a measurement result report.

[0321] To supplement step E14, after the step of obtaining the measurement result of the first communication device, the method may include:

[0322] Step E141: If the measurement result is greater than a preset tenth threshold or the sum of the measurement result and the second hysteresis parameter is greater than the tenth threshold, the measurement result of the first communication device satisfies the second condition.

[0323] Optionally, first determine whether the measurement result is greater than a preset tenth threshold (a custom threshold regarding the measurement result); or, determine whether the sum of the measurement result and the second lag parameter is greater than the tenth threshold; if the measurement result is greater than the preset tenth threshold or the sum of the measurement result and the second lag parameter is greater than the tenth threshold, then determine that the measurement result of the first communication device meets the second condition.

[0324] Specifically, the measurement process of the UE may further include a second measurement event: that is, the UE measures a PCell reference signal, such as a CSI-RS (Channel State Information Reference Signal, a reference signal for downlink channel state information measurement), a DMRS (Demodulation Reference Signal, a demodulation reference signal), etc.:

[0325] If Mp+Hys2>Thresh2_meas or Mp>Thresh2_meas, it is determined that the second condition is met, and the measurement related information is recorded in the test report. Wherein Mp is the measurement result of PCell (such as RSRP, RSRQ, RSSI, SINR, RSCP or EcN0 of the reference signal), Hys2 is the second hysteresis parameter, and Thresh2_meas is the second threshold of the measurement result, that is, the tenth threshold.

[0326] It should be noted that the measurement events are not limited to the above-mentioned ones, and only two examples are given here as examples.

[0327] In addition, after obtaining the test report corresponding to the first measurement event and / or the second measurement event, it is possible to further determine whether the measurement result meets the sending condition of the measurement report, and the sending condition may be to meet at least one of the first condition and the second condition.

[0328] The measurement report and / or service requirement information sent by the UE to the PCell includes at least one of the following information: the measurement result of the first measurement event, such as RSRP, RSRQ, SINR, RSSI of the SCell reference signal; the measurement result of the second measurement event, such as RSRP, RSRQ, SINR, RSSI of the PCell reference signal; UE's own service requirement information, such as QoS (Quality of Service) requirements of the service requirements.

[0329] The present application also provides a synchronization signal period setting method applied to a third communication device, wherein the third communication device is in communication connection with at least one first communication device and / or at least one second communication device. For the sake of convenience, the description of the steps of the method will use numbers starting with F. The method includes:

[0330] Step F10, obtaining a corresponding second communication device according to the measurement result report and / or the service requirement information;

[0331] Step F20: Send service demand information to the second communication device.

[0332] The embodiment of the present application also provides a communication method mainly based on the communication and computing processing between the SCell and the UE. Different from the aforementioned embodiment, after obtaining the measurement result report, the UE selects the optimal SCell based on its own computing resources, and directly sends the corresponding service demand information to the selected SCell, so that the SCell can determine the corresponding UE request quantity information when it implements the SCell function, so as to further determine the corresponding second SSB sending period according to the UE request quantity information under the SCell function and the UE request quantity information under the non-SCell function (including CA scenarios and non-CA scenarios), and complete the update of the current SSB sending period.

[0333] The present application also provides a communication method based on an activation instruction, which is applied to a first communication device, wherein the first communication device is in communication connection with at least one second communication device and at least one third communication device. For the sake of convenience, the description of the steps of the method will use numbers starting with G. Figure 8 , the communication method comprises:

[0334] Step G10, sending a cycle setting instruction and / or an activation instruction to the fourth communication device;

[0335] The fourth communication device refers to a communication device that needs to be activated, that is, a candidate second communication device, and activating the fourth communication device refers to allowing the fourth communication device to provide communication services for the third communication device.

[0336] Step G20, receiving acceptance information sent by the fourth communication device, and / or synchronization signal sending period information sent by the fourth communication device, and / or rejection information sent by the fourth communication device.

[0337] In a feasible embodiment, the first communication device includes a base station corresponding to a primary cell (i.e., PCell), the second communication device includes a base station corresponding to an unactivated secondary cell (i.e., SCell) corresponding to the third communication device, the third communication device includes a terminal device (i.e., UE), and the fourth communication device includes a candidate activated secondary cell.

[0338] The embodiment of the present application provides a method for updating the SSB transmission period of the SCell based on the period setting instruction or the activation instruction. Before step G10, the SCell sends its own SSB configuration information to the PCell, and the PCell obtains the cache status information of the UE, the wireless connection instruction and / or the user load of the SCell, and then further selects an unactivated optimal SCell from the associated SCells as a candidate SCell (i.e., the fourth communication device). The optimal SCell refers to the SCell that can provide the highest quality communication service to the UE device among the SCells associated with the UE device. When evaluating the service quality provided by each SCell to the UE, the parameters such as the cache status information of the UE, the wireless connection quality and / or the user load of each SCell can be used, and weighted calculation and evaluation are performed according to the actual situation.

[0339] After the PCell determines the candidate SCell corresponding to the UE, it sends a period setting instruction and / or an activation instruction to the candidate SCell, where the period setting instruction is used to instruct the candidate SCell to update the current SSB sending period to a specified value, and the activation instruction is used to instruct the candidate SCell to be activated as the SCell corresponding to the UE, provide services for the UE, and set the UE to an activated state, so that it will no longer be selected as a candidate SCell for other UEs.

[0340] Before step G10, the method further includes:

[0341] A fourth communication device is obtained from the at least one second communication device.

[0342] It should be noted that when determining the fourth communication device, the cache status information of the third communication device, the wireless connection quality and / or the user load of each second communication device or other information that can characterize the status of the third communication device can be used as a basis to determine a relatively better candidate second communication device.

[0343] Specifically, the step of obtaining the fourth communication device from at least one second communication device may include:

[0344] A fourth communication device is obtained from at least one second communication device according to the buffer status information of the third communication device, the measurement result, and at least one item of the user load information of the at least one second communication device.

[0345] Further, the measurement result may include: a measurement result obtained by the third communication device measuring the second communication device.

[0346] Furthermore, the measurement result may also include: at least one of RSRP, RSRQ, RSSI and SINR.

[0347] In a feasible embodiment, after receiving the acceptance information sent by the fourth communication device, the method further includes:

[0348] Step G30: Send activation information corresponding to the fourth communication device to the third communication device.

[0349] If the acceptance information sent by the fourth communication device is received, it means that the fourth communication device has determined that it can be activated and supports the activation operation. Therefore, in this case, the first communication can send the activation information corresponding to the fourth communication device to the third communication device to synchronize the activation status of the corresponding fourth communication device on the third communication device side.

[0350] Specifically, after the SCell receives the cycle setting instruction and / or activation instruction, it can first determine whether to receive the instruction based on the current SSB transmission cycle and load information. For example, if the current SSB transmission cycle is inconsistent with the cycle indicated in the cycle setting instruction, the current SSB transmission cycle can be updated to be consistent with the cycle indicated in the cycle setting instruction (such as T1), and an acceptance message is sent to the PCell; or, if the cycle indicated by the cycle setting instruction is T1, but the SCell determines that it does not support updating the current SSB transmission cycle to T1 based on its own load information, it determines that the cycle setting instruction is not accepted, and sends a rejection message to the PCell; or, although the SCell has updated the current SSB transmission cycle, the updated SSB transmission cycle is not T1, and a rejection message is also sent to the PCell.

[0351] That is, when the PCell receives an acceptance message sent by the candidate SCell, the candidate SCell is activated and determined as the SCell corresponding to the UE, and communication services are provided to the UE through the SCell.

[0352] In a feasible embodiment, after receiving the rejection information sent by the fourth communication device, the method includes:

[0353] Step G40, obtaining a fifth communication device from at least one second communication device;

[0354] And / or, step G50, sending a cycle setting instruction and / or an activation instruction to the fifth communication device;

[0355] And / or, step G60, receiving acceptance information sent by the fifth communication device, and / or, synchronization signal sending cycle information sent by the fifth communication device, and / or, rejection information sent by the fifth communication device.

[0356] It can be understood that when the PCell receives the rejection information sent by the candidate SCell, it needs to find another fifth communication device, and send a period setting instruction and / or an activation instruction to it according to the same processing method as the previous fifth communication device, and receive the acceptance information, synchronization signal sending period, or rejection information sent by the fifth communication device.

[0357] That is, after the candidate SCell refuses to be activated, the next candidate SCell is searched from other inactivated SCells except the SCell, and the process returns to step G10, and so on.

[0358] Further, in a feasible embodiment, the step of sending a cycle setting instruction and / or an activation instruction to the candidate second communication device includes:

[0359] To supplement step G10, in step G11, if the current synchronization signal sending period of the fourth communication device meets the third condition, a period setting instruction and / or an activation instruction is sent to the fourth communication device.

[0360] Before sending a cycle setting instruction to the fourth communication device, it is necessary to determine whether the current synchronization signal sending cycle meets the preset third condition. If so, a cycle setting instruction and / or an activation instruction can be sent. If not, it means that the fourth communication device's own cycle meets the requirements of providing communication services to the third communication device, and there is no need to send a cycle setting instruction and / or an activation instruction.

[0361] In a feasible embodiment, the third condition at least includes: the synchronization signal sending period of the fourth communication device is greater than or equal to a first preset period threshold, and the first preset period threshold is a pre-set period threshold used to determine whether to send a period setting instruction and / or an activation instruction to the fourth communication device. If the synchronization signal sending period is less than the first preset period threshold, it means that there is no need to further shorten the synchronization signal sending period of the fourth communication device.

[0362] In an embodiment of the present application, the PCell may send one of a period setting instruction or an activation instruction to the candidate SCell, or may send both a period setting instruction and an activation instruction to the candidate SCell at the same time.

[0363] Specifically, in order to ensure that the activated SCell provides better communication services for the UE, when the current synchronization signal transmission period is greater than or equal to the first preset period threshold (for example, greater than T1), when activating the candidate SCell, it is necessary to instruct the SCell to update the current SSB transmission period to T1 (i.e., a period less than the preset period threshold), and T1 can also be the shortest period of the optional transmission period of the SCell. If the current SSB transmission period of the candidate SCell is T1, there is no need to send a period setting instruction, and only an activation instruction can be sent.

[0364] It should also be noted that the activation instruction may also include a field or identifier for instructing the candidate SCell to update the SSB transmission period to the indicated SSB transmission period.

[0365] In another feasible embodiment, after the step of sending a cycle setting instruction and / or an activation instruction to the candidate second communication device, the communication method may further include:

[0366] When the current synchronization signal transmission period received from the fourth communication device does not meet the first condition, the fourth communication device is not activated, and the first condition is a condition that needs to be met to activate the fourth communication device;

[0367] When the current synchronization signal sending period received from the fourth communication device meets the first condition, the fourth communication device is activated as the secondary cell corresponding to the terminal device (ie, UE), and the first condition is a condition that needs to be met to activate the fourth communication device.

[0368] In a feasible embodiment, the first condition may include: being less than or equal to a second preset period threshold, and the second preset period threshold is adaptively set according to actual conditions to determine whether the second communication device meets the activation condition.

[0369] It can be understood that after the candidate SCell determines to accept or reject the period setting instruction or activation sent by the PCell, in addition to returning the acceptance or rejection information to the PCell, the current SSB transmission period can also be fed back to the PCell.

[0370] The first preset period is the shortest period corresponding to the candidate SCell. When the current SSB sending period received by the PCell from the candidate SCell is greater than the first preset period T1, it can be determined that the candidate SCell has rejected the instruction to update the current SSB sending period to T1 or activate. At this time, the next candidate SCell can be selected from the unactivated SCell.

[0371] When the current SSB period received by the PCell from the candidate SCell is equal to the first preset period, it can be determined that the candidate SCell has updated the current SSB sending period to T1 and received the activation instruction. At this time, the candidate SCell can be activated to associate the SCell with the UE and provide communication services to the UE through the SCell.

[0372] In addition, in addition to sending the current SSB cycle to the PCell, the SCell can also send the current operating status to the PCell and the UE to complete information synchronization.

[0373] In another feasible embodiment, after the step of not activating the fourth communication device, the method further includes:

[0374] Step G40, obtaining a fifth communication device from at least one second communication device;

[0375] And / or, step G50, sending a cycle setting instruction and / or an activation instruction to the fifth communication device;

[0376] And / or, step G60, receiving acceptance information sent by the fifth communication device, and / or, synchronization signal sending cycle information sent by the fifth communication device, and / or, rejection information sent by the fifth communication device.

[0377] It can be understood that after the PCell determines not to activate the fourth communication device, it needs to find another fifth communication device as a candidate SCell, and send period setting instructions and / or activation instructions to it according to the same processing method as the previous fifth communication device, and receive the acceptance information, synchronization signal sending period, or rejection information sent by the fifth communication device.

[0378] It should be noted that the processing steps here are consistent with the aforementioned processing steps after receiving the rejection message sent by the fourth communication device, and will not be repeated here.

[0379] For example, refer to Fig. 9, a step of implementing data transmission and processing for each device corresponding to the communication method based on an activation instruction may include: Step 1, SCell sends SSB configuration information to PCell; Step 2, PCell selects "candidate activated SCell"; Step 3, PCell sends an activation indication to the candidate activated SCell, or instructs its SSB transmission period to be updated to T1; Step 4, if SCell receives an update indication that the SSB transmission period should be T1, or receives an activation indication, and the current SSB transmission period is not T1, the SSB transmission period can be set to T1; Step 5, SCell sends an SSB transmission period, or a "receive / reject" message to PCell; Step, if the SSB transmission period of the "candidate activated SCell" is greater than a threshold (i.e., greater than a first preset period), or receives a "reject" message, the PCell will not activate the SCell; Step 7, PCell informs the UE of the SSB transmission period.

[0380] The present application also provides a communication method applied to a second communication device, wherein the second communication device is connected to at least one first communication device and / or at least one third communication device for communication. For the sake of convenience, the description of the steps of the method will use numbers starting with I. Fig.10 , the communication method comprises:

[0381] Step I10, receiving a cycle setting instruction and / or an activation instruction sent by the first communication device;

[0382] Step I20, sending second information to the first communication device, the second information including at least one of acceptance information, synchronization signal sending cycle information, and rejection information.

[0383] In a feasible embodiment, the first communication device includes a base station corresponding to a primary cell (ie, PCell), the second communication device includes a base station corresponding to a secondary cell (ie, SCell), and the third communication device includes a terminal device (ie, UE).

[0384] Among them, after receiving the cycle setting instruction and / or activation instruction sent by the first communication device, the second communication device can choose to receive or reject according to its own actual situation, and can also choose to send the current synchronization signal sending cycle after acceptance or rejection to the first communication device to synchronize the synchronization signal sending cycle.

[0385] Further, the step of sending the second information to the first communication device may include:

[0386] Step I30: if the cycle setting instruction and / or activation instruction is accepted, sending acceptance information and / or synchronization signal sending cycle information to the first communication device;

[0387] Step I40: If the cycle setting instruction and / or activation instruction is not accepted, a rejection message and / or synchronization signal sending cycle information is sent to the first communication device.

[0388] It should be noted that when the SSB transmission period of the SCell is updated based on an activation instruction or a period setting instruction, the SCell first needs to send its own SSB configuration information to the PCell so that it can select the best candidate PCell corresponding to a UE from multiple associated SCells.

[0389] Specifically, the PCell obtains the cache status information, wireless connection instructions and / or user load of the SCell of the UE, and then further selects an inactivated optimal SCell from the associated SCells as a candidate SCell. The optimal SCell refers to the SCell that can provide the highest quality communication service to the UE device among the SCells associated with the UE device. When evaluating the service quality provided by each SCell to the UE, the parameters such as the cache status information of the UE, the wireless connection quality and / or the user load of each SCell can be used, and weighted calculation and evaluation can be performed according to the actual situation.

[0390] After the PCell determines the candidate SCell corresponding to the UE, it sends a period setting instruction and / or an activation instruction to the candidate SCell, where the period setting instruction is used to instruct the candidate SCell to update the current SSB sending period to a specified value, and the activation instruction is used to instruct the candidate SCell to be activated as the SCell corresponding to the UE, provide services for the UE, and set the UE to an activated state, so that it will no longer be selected as a candidate SCell for other UEs.

[0391] Further, in a feasible embodiment, if a cycle setting instruction and / or an activation instruction is accepted, the method further includes:

[0392] To supplement step I20, in step I21, the second communication device is activated as the second communication device corresponding to the third communication device, and / or sets the synchronization signal sending period according to the period setting instruction.

[0393] Specifically, after the SCell receives the cycle setting instruction and / or activation instruction, it can first determine whether to receive the instruction based on the current SSB transmission cycle and load information. For example, if the current SSB transmission cycle is inconsistent with the cycle indicated in the cycle setting instruction, the current SSB transmission cycle can be updated to be consistent with the cycle indicated in the cycle setting instruction (such as T1), and an acceptance message is sent to the PCell; or, if the cycle indicated by the cycle setting instruction is T1, but the SCell determines that it does not support updating the current SSB transmission cycle to T1 based on its own load information, it determines that the cycle setting instruction is not accepted, and sends a rejection message to the PCell; or, although the SCell has updated the current SSB transmission cycle, the updated SSB transmission cycle is not T1, and a rejection message is also sent to the PCell.

[0394] When the PCell receives a reception message sent by a candidate SCell, the candidate SCell is activated and determined as the SCell corresponding to the UE, and communication services are provided to the UE through the SCell. When the PCell receives a rejection message sent by a candidate SCell, the next candidate SCell is searched from other SCells except the SCell, and the process returns to step G10, and so on.

[0395] Further, step I10 is supplemented. In a feasible embodiment, after the step of receiving the cycle setting instruction and / or activation instruction sent by the first communication device, the method further includes:

[0396] Step I12: if the second communication device cannot set the current synchronization signal transmission period to a period that satisfies the first condition, sending rejection information and / or synchronization signal transmission period information to the first communication device;

[0397] Step I13: if the second communication device is able to set the current synchronization signal transmission period to a period that satisfies the first condition, then sending acceptance information and / or synchronization signal transmission period information to the first communication device;

[0398] In a feasible embodiment, before step I12, the following may be further included: step I11, if the current synchronization signal transmission cycle does not meet the first condition, the first condition is a condition that needs to be met to activate the second communication device. If step I11 is met, step I12 is then executed.

[0399] Among them, the first condition may be less than or equal to the second preset cycle threshold value. When the synchronization signal transmission period sent by the fourth communication device is less than the second preset cycle threshold value, it indicates that the support sets the current synchronization signal transmission period to a relatively small period (specifically, less than the second preset cycle threshold value) to meet the communication needs of the terminal device. Whether the second communication device can set the current synchronization signal transmission period to a period that meets the first condition depends on its own load.

[0400] It can be understood that the embodiment of the present application also provides a method for the SCell to determine whether it should accept the cycle setting instruction or activation instruction sent by the PCell based on its own load, wherein the cycle setting instruction or activation instruction can be used to instruct the SCell to update the SSB sending period to the first preset period T1 (or the shortest period among the optional periods), and the SCell can determine whether to accept the instruction and update the current SSB sending period to T1 based on the actual load conditions.

[0401] The load situation may include information on the number of UEs associated with the SCell that need services provided by the SCell, including information on the number of UEs in CA scenarios and non-CA scenarios. If the number of UEs is too large and it is difficult to provide communication services for new UEs, updating the current SSB sending period to T1 is not supported, and the period setting instructions or activation instructions sent by the PCell cannot be accepted.

[0402] In the embodiment of the present application, the SCell determines whether to be activated and / or updates the current SSB sending cycle based on actual conditions, taking into account the load conditions of the SCell, avoiding overload conditions, and ensuring the normal operation and communication quality of the SCell.

[0403] The embodiment of the present application proposes an SCell energy saving strategy, which is related to the activation / deactivation process of the SCell. The PCell will select a "candidate activated SCell" and send a "target SSB transmission period" or an activation indication to it; the SCell will determine the updated SSB transmission period and return information to the PCell; if the updated SSB transmission period of the SCell is not T1, the PCell will not activate the SCell. In this way, it can be ensured that the SCell activated by the UE has a smaller SSB transmission period, thereby ensuring the service quality of the UE.

[0404] The present application also provides a communication method based on a deactivation instruction, which is applied to a first communication device, wherein the first communication device is in communication connection with at least one second communication device and / or at least one third communication device. For the sake of convenience, the description of the steps of the method will use numbers starting with J. The communication method includes:

[0405] Step J10: Send a deactivation instruction to the deactivated second communication device.

[0406] In a feasible embodiment, the first communication device includes a base station corresponding to a primary cell (i.e., PCell), the second communication device includes a base station corresponding to an unactivated secondary cell (i.e., SCell) corresponding to the third communication device, the third communication device includes a terminal device (i.e., UE), and the fourth communication device includes a candidate activated secondary cell.

[0407] In an embodiment of the present application, when the PCell implements the SSB sending period update for the SCell, it can determine the corresponding deactivated cell based on information such as the wireless connection quality between the SCell and the UE, inactivity information and / or UE service requirements.

[0408] It can be understood that a deactivated auxiliary cell refers to an SCell that needs to appropriately extend the SSB transmission period to save energy. The worse the wireless connection quality, the longer the inactive timing information, or the less the UE service demand, the more inclined to determine the SCell as a deactivated SCell. The specific process of determining the deactivated SCell through these three types of information can be set according to actual needs and is not limited here. For example, the three types of information of the SCell are scored separately, and when the score reaches a certain threshold, the SCell is determined as a deactivated SCell.

[0409] It should be noted that the deactivation instruction is used to instruct the deactivated SCell to extend the current SSB transmission period, and for the deactivated SCell, the current SSB transmission period can be extended according to the number of deactivation instructions received from each PCell within a preset time period. For example, the more deactivation instructions are received, the longer the SSB transmission period is, or when the number of deactivation instructions is within different thresholds, different SSB transmission periods are determined respectively.

[0410] In addition, in the case where the SSB transmission period of the SCell is updated or not updated, the SCell can send the current SSB transmission period to the PCell and inform the UE via the PCell to achieve information synchronization of the SSB transmission period.

[0411] Before step J10, the method may further include:

[0412] Obtaining a fourth communication device from at least one second communication device, the fourth communication device comprising a second communication device that is a candidate for deactivation;

[0413] Optionally, obtaining the fifth communication device from at least one activated second communication device comprises:

[0414] The fifth communication device is obtained from the at least one activated second communication device according to the wireless connection quality of the at least one second communication device, and / or the inactivity timing information, and / or the service demand of the third communication device.

[0415] Exemplarily, when a communication method based on a deactivation instruction is executed by each device, the communication process and / or processing process between the devices is as follows: Fig.11 As shown, the specific steps include: Step 1, SCell sends SSB configuration information to PCell; Step 2, PCell selects the SCell that should be deactivated; Step 3, PCell sends a deactivation indication to the SCell; Step 4, if the number or proportion of deactivation indications received by SCell within a certain time T is greater than a certain threshold, the SSB sending period can be extended; Step 5, SCell informs PCell of the SSB sending period; Step 6, PCell informs UE of the SSB sending period.

[0416] The present application also provides a communication method based on a deactivation instruction, which is applied to a second communication device, wherein the second communication device is connected to at least one first communication device and / or at least one third communication device for communication. For the sake of convenience, the description of the steps of the method will use numbers starting with L. Fig.12 , the communication method comprises:

[0417] Step L10, receiving a deactivation instruction sent by the first communication device;

[0418] Step L20, setting the current synchronization signal sending period according to the number of deactivation instructions received within a preset time period.

[0419] In a feasible embodiment, the first communication device includes a base station corresponding to a primary cell (i.e., PCell), the second communication device includes a base station corresponding to an unactivated secondary cell (i.e., SCell) corresponding to the third communication device, the third communication device includes a terminal device (i.e., UE), and the fourth communication device includes a candidate activated secondary cell.

[0420] It should be noted that before PCell selects SCell, SCell needs to send SSB configuration information to PCell first. When PCell selects the deactivated SCell, it can determine the corresponding deactivated cell based on information such as the wireless connection quality between SCell and UE, inactivity information and / or UE service requirements.

[0421] Among them, the deactivated auxiliary cell refers to the SCell that needs to appropriately extend the SSB transmission cycle to save energy. When the wireless connection instruction is poor, the longer the inactive timing information is, and the less the UE service demand is, the more inclined to determine the SCell as a deactivated SCell. The specific process of determining the deactivated SCell through these three types of information can be set according to actual needs and is not limited here. For example, the three types of information of the SCell are scored separately, and when the score reaches a certain threshold, the SCell is determined as a deactivated SCell.

[0422] It should be noted that the deactivation instruction is used to instruct the deactivated SCell to extend the current SSB transmission period, and for the deactivated SCell, the current SSB transmission period can be extended according to the number of deactivation instructions received from each PCell within a preset time period. For example, the more deactivation instructions are received, the longer the SSB transmission period, or when the number of deactivation instructions is within different thresholds, different SSB transmission periods are determined.

[0423] In another feasible embodiment, when the SCell receives a deactivation indication instruction from all PCells associated with it, and the number of UEs required by the SCell as a non-SCell service cell is lower than a threshold (including when there is no UE demand), the SSB sending frequency can be appropriately reduced, that is, the SSB sending period can be extended.

[0424] In addition, in the case where the SSB transmission period of the SCell is updated or not updated, the SCell can send the current SSB transmission period to the PCell and inform the UE via the PCell to achieve information synchronization of the SSB transmission period.

[0425] Further, in a feasible embodiment, the step of setting the current synchronization signal sending period according to the quantity information of the deactivation instructions received within the preset time period may include:

[0426] To supplement step L20, in step L21, if the number of deactivation instructions received within the preset time period meets the second condition, which is the condition that must be met to deactivate the second communication device, the current synchronization signal sending period is set to be greater than the current period, or the current synchronization signal sending period is increased.

[0427] In a feasible embodiment, the second condition includes: the number of deactivation instructions received within a preset time period is greater than a preset threshold or a preset ratio. For example, the preset ratio is the ratio of the number of deactivation instructions to the total number of user requests for the secondary cell when the serving cell function is realized.

[0428] Exemplarily, if the SCell has three selectable SSB sending cycles, within a period of time T, when the number of deactivation instruction information received by the SCell from each PCell is greater than or equal to Thresh_deactivation, where Thresh_deactivation is the deactivation instruction number threshold (i.e., the preset threshold), if the current SSB sending cycle is not T3 (i.e., the longest cycle), the current SSB sending cycle is updated to T3; if the current SSB sending cycle is T3, the current SSB sending cycle remains unchanged.

[0429] If the SCell has two selectable SSB sending cycles, within a period of time T, when the number of deactivation instructions received by the SCell from each PCell is greater than or equal to Thresh_deactivation, where Thresh_deactivation is the deactivation instruction number threshold (i.e., the preset threshold), if the current SSB sending cycle is not T2 (i.e., the longest cycle), the current SSB sending cycle is updated to T2; if the current SSB sending cycle is T2, the current SSB sending cycle remains unchanged.

[0430] In addition, the aforementioned deactivation instruction quantity threshold can be replaced by a preset ratio, where the preset ratio refers to the ratio of the deactivation instruction quantity information received by the SCell to the total number of all UEs served by the SCell as a serving cell. For example, when the preset ratio is 100%, it means that when the deactivation instruction is sent in all associated PCells, the step of updating the current SSB transmission period to the longest period among the optional periods is executed.

[0431] If the SSB transmission period of the SCell is changed, the updated SSB transmission period is sent to the following objects but not limited to: in the CA scenario, when the cell is used as the SCell, all associated PCells. Or, the current SSB transmission period is sent to the following objects but not limited to: in the CA scenario, when the cell is used as the SCell, all associated PCells.

[0432] In the technical solution of the embodiment of the present application, after the SCell is deactivated, it is allowed to determine whether to increase the SSB transmission period. When the load of the SCell is small, the SSB transmission period can be appropriately extended, thereby reducing the overhead of the broadcast signal and unnecessary energy consumption, achieving the purpose of energy saving and reducing operator costs.

[0433] The present application also provides a communication device applied to a first communication device, referring to Fig.13 , the communication device comprises:
