Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a communication method, device, equipment and storage medium. Background Art

[0002] Network Energy Saving (NES) is playing a positive role in improving environmental sustainability, reducing negative environmental impacts and reducing operating costs. Network energy saving helps reduce the energy consumption burden of communication operators and user equipment (UE), and can effectively reduce pollution events that have a harmful impact on the environment, such as greenhouse gas emissions. At present, due to the widespread use of 5G networks in various industries and regions, users' demand for high data rate (such as XR) services and applications is increasing, and business services and applications have significantly increased their requirements for transmission rate, reliability and security. To meet these needs, communication operators have introduced more antennas, larger bandwidths and more frequency bands, resulting in a denser 5G network structure. Therefore, while improving the performance of 5G networks, operators also need to propose new solutions to improve network energy efficiency and reduce the negative impact of 5G networks on the environment.

[0003] For intra-band carrier aggregation (intra-band CA) scenarios, as long as the UE supports this function, it can synchronize time and frequency with the SCell through the PCell without the need for the SSB broadcast by the SCell. However, in inter-band CA scenarios, due to the large TA error between the primary and secondary cells, it will be more difficult to use the PCell notification method to assist the UE and SCell in synchronization, so the application of the SSB-less SCell solution also faces greater challenges. In order to maintain a balance between the UE's service quality and the base station's energy-saving gain, a state switching solution needs to be designed so that the SCell can dynamically adjust the SSB transmission period.

[0004] The on-demandSSB solution is a solution that can effectively reduce the SCell activation time (to ensure UE service quality) and ensure base station energy saving gain (to ensure switching accuracy). In the 5G scenario where the on-demandSSB solution is applied, the SCell in a fully dormant state does not need to send SSB or sends SSB at a lower frequency. It only sends on-demandSSB when needed. The UE can perform time-frequency synchronization and delay adjustment with the SCell through on-demandSSB.

[0005] Since the SCell sends on-demand SSB only when there is a demand (the demand may be indicated by the PCell or UE), if the on-demand SSB is sent a fixed number of times, the UE may miss the on-demand SSB and lose the synchronization opportunity, which will increase the SCell activation time of the UE or even lose the activation opportunity.

[0006] The above contents are only used to assist in understanding the technical solution of the present invention and do not constitute an admission that the above contents are prior art. Summary of the invention

[0221] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0222] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0223] The execution subject of this embodiment may be a first cell with data processing, network communication and program running functions, such as SCell (Secondary Cell, SCell), or a cell corresponding to the first cell, or a communication base station to which the first cell belongs, or a communication device capable of implementing the above functions. The following takes the first cell as an example to illustrate this embodiment and the following embodiments.

[0224] Network Energy Saving (NES) is playing a positive role in improving environmental sustainability, reducing negative environmental impacts and lowering operating costs. Network Energy Saving helps to reduce the energy consumption burden of communication operators and user equipment (UE), and can effectively reduce pollution events that have a harmful impact on the environment, such as greenhouse gas emissions. Currently, due to the widespread use of 5G networks in various industries and regions, users' demand for high data rate (such as XR) services and applications is increasing, and business services and applications have significantly increased their requirements for transmission rate, reliability and security. To meet these needs, communication operators have introduced more antennas, larger bandwidths and more frequency bands, resulting in a denser 5G network structure.

[0225] Therefore, while improving the performance of 5G networks, operators also need to propose new solutions to improve network energy efficiency and reduce the negative impact of 5G networks on the environment. At present, the energy cost of mobile networks accounts for about 23% of the total cost of operators, most of which comes from the AAU part of the radio access network. In order to further reduce energy costs, it is necessary for operators to further study and develop network energy consumption models for base stations, and use feedback from terminals, auxiliary information, and information exchange on network interfaces to achieve more efficient dynamic and semi-static operations, as well as more fine-grained transmission and reception adaptation. At the same time, the potential benefits of network energy consumption and the impact on network performance should also be evaluated in real time to ensure that in most cases, key performance indicators such as spectrum efficiency, capacity, user experience, latency, and device power consumption will not be seriously affected.

[0226] Due to the technology, the on-demand SSB solution is a solution that can effectively reduce the activation time of the first cell (to ensure the service quality of the communication equipment) and ensure the energy saving gain of the base station (to ensure the accuracy of switching). In the 5G scenario where the on-demand SSB solution is applied, the first cell in a completely dormant state does not need to send synchronization signal blocks or sends synchronization signal blocks at a lower frequency. It only sends on-demand synchronization signal blocks when there is a need. The communication equipment can perform time-frequency synchronization and delay adjustment with the first cell through the on-demand synchronization signal blocks. The first cell sends on-demand synchronization signal blocks only when there is a need (the need may be indicated by the second cell or the communication equipment). If the on-demand synchronization signal blocks are sent a fixed number of times, the communication equipment may miss the on-demand synchronization signal blocks and lose the synchronization opportunity, which will increase the activation time of the first cell of the communication equipment or even lose the activation opportunity.

[0227] The present application provides a solution, receiving activation request information, the activation request information is sent by a second cell, the second cell is a network device; sending one or more synchronization signal blocks. It is realized that the network device controls the sending of synchronization signal blocks through the activation request information, and sends, for example, on-demand synchronization signal blocks, to ensure that the network device sends on-demand synchronization signal blocks only when there is a demand (the demand may be indicated by the second cell or the communication device), so as to save energy consumption while ensuring the signal synchronization function.

[0228] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a first cell or its corresponding base station, etc. The following takes the first cell or its corresponding base station as an example to illustrate this embodiment and the following embodiments.

[0229] Based on this, the present application embodiment provides a communication method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the communication method of the present application.

[0230] In this embodiment, the communication method includes the following steps:

[0231] Step S101: receiving activation request information, where the activation request information is sent by a second cell, where the second cell is a network device.

[0232] It should be noted that the first cell may be an SCell (Secondary Cell), or a cell corresponding to the first cell, or a communication base station to which the first cell belongs. The above-mentioned first cell may be in a dormant state when idle, and when it is necessary to provide corresponding services for a communication device (such as a terminal device), it is turned on or enters an on state or sends a synchronization signal block to provide communication services for the communication device.

[0233] It should be noted that the second cell is a network device, for example, the second cell may be a PCell (Primary Cell) or a base station corresponding to the second cell, and the activation request information is sent by the second cell, for example, the second cell sends the activation request information to the first cell.

[0234] It is clear that receiving the activation request information indicates that it believes that there may be a communication device that needs to provide services, that is, to switch the state such as the on state or semi-dormant state, or control the device to perform a certain function such as sending a synchronization signal block at a certain frequency; and / or switch to the on state according to the activation request information; send a synchronization signal block (SSB) at the basic frequency. The basic frequency refers to the frequency used by the device by default, which is generally configured according to the actual business situation.

[0235] In addition, when receiving the activation request information, it is also possible to switch to a semi-dormant state; send a synchronization signal block according to the frequency in the semi-dormant state. In the semi-dormant state, the first cell may reduce the transmission rate, reduce resource allocation, or limit specific types of services, wherein the frequency in the semi-dormant state is lower than the transmission frequency in the normal on state, for example, lower than the above-mentioned basic frequency.

[0236] Step S102: Send one or more synchronization signal blocks.

[0237] It should be understood that the synchronization signal block can be an SSB (Synchronous Signal Block). The on-demand synchronization signal block solution is a solution that can effectively reduce the activation time of the first cell (to ensure the service quality of the communication equipment). The communication equipment can be a user equipment (UE) and ensure the energy saving gain of the base station (to ensure the accuracy of switching). In the 5G scenario where the on-demand synchronization signal block solution is applied, the first cell in a completely dormant state does not need to send a synchronization signal block or sends a synchronization signal block at a lower frequency. It only sends an on-demand synchronization signal block when there is a need. The communication equipment (user terminal) can perform time-frequency synchronization and delay adjustment with the first cell through the on-demand synchronization signal block. At present, Rel-18 has not yet applied the on-demand synchronization signal block solution to the carrier aggregation scenario.

[0238] It is understandable that the on-demand synchronization signal block solution has not yet been applied to the carrier aggregation scenario, and the implementation details of the solution in the carrier aggregation scenario need further study. Since the first cell sends the on-demand synchronization signal block only when there is a demand (the demand may be indicated by the second cell or the communication device), if the on-demand synchronization signal block is sent a fixed number of times, the communication device may miss the on-demand synchronization signal block and lose the synchronization opportunity, which will increase the activation time of the first cell of the communication device or even lose the activation opportunity.

[0239] Therefore, this embodiment sends one or more synchronization signal blocks to complete synchronization. Further, one or more synchronization signal blocks are sent based on the activation request information. The transmission control of the synchronization signal block is effectively completed according to the information of the second cell, ensuring that the communication device will not miss the on-demand synchronization signal block and lose the synchronization opportunity, and also avoiding the energy waste of frequently sending the on-demand synchronization signal block.

[0240] In some embodiments, the synchronization signal block is an on-demand synchronization signal block, that is, a synchronization signal block sent by the first cell periodically or aperiodically and can be used to perform a specific function. An on-demand synchronization signal block is a synchronization signal block sent according to demand, that is, a synchronization signal block sent according to activation request information periodically or aperiodically and can be used to perform a specific function, for example: the demand is determined according to the demand corresponding to the activation request information or the configuration or setting information of the device itself, and a synchronization signal block for performing a specific function such as signal synchronization or measurement is sent according to the demand.

[0241] Specifically, in order to further explain the broadcast on-demand synchronization signal block in this embodiment, this embodiment proposes the following implementation method for explanation. After the communication device detects the on-demand synchronization signal block, the communication device further completes the identification of the cell ID and accurate time synchronization according to the on-demand synchronization signal block. In addition, after the communication device detects the on-demand synchronization signal block, the communication device performs a measurement function according to the on-demand synchronization signal block. For example, the communication device can perform L1 / L3 measurement by specifying the on-demand synchronization signal block of the second cell based on the configuration information.

[0242] An on-demand synchronization signal block retransmission mechanism / process is designed through an energy-saving solution, so that the communication device can send an on-demand synchronization signal block retransmission request to the second cell when the count times out or after the count times out, thereby improving the overall success rate of synchronization / measurement operations between the communication device and the first cell.

[0243] In this embodiment, the activation request information may include at least one of the following: indication information that the first cell needs to switch to a first target state; indication information that the first cell needs to switch the synchronization signal block sending frequency to the first target sending frequency; indication information that the first cell needs to send a synchronization signal block on designated resources; indication information that the first cell needs to send a synchronization signal block.

[0244] Among them, in the indication information that the first cell needs to switch to the first target state, the first target state refers to the on state, or the semi-dormant state, wherein the on state, or the semi-dormant state is the state in which the second cell indicates that the first cell needs to switch, wherein the state of the first cell includes the on state, the semi-dormant state and the dormant state, wherein the on state is the on state of the first cell, indicating that the first cell is sending synchronization signal blocks at the basic frequency; when the first cell is in the semi-dormant state, it limits data transmission and power consumption, and sends synchronization signal blocks at a sending frequency lower than the basic frequency; when the first cell is in the dormant state, it temporarily stops sending synchronization signal blocks and minimizes power consumption.

[0245] In addition, the first cell needs to switch the synchronization signal block transmission frequency to the indication information of the first target transmission frequency, where the synchronization signal block transmission frequency is the frequency of the synchronization signal block at a fixed period, and the first target transmission frequency is a fixed synchronization signal block transmission frequency set by the network. For example: in the on state, the first cell can send an on-demand synchronization signal block every 10ms.

[0246] Furthermore, the first cell needs to send indication information of the synchronization signal block on designated resources, where the designated resources refer to specific resource blocks allocated to the synchronization signal blocks in the frequency and time domains, and these resource blocks are usually planned during network design to ensure that the synchronization signal blocks can be reliably broadcast and received.

[0247] And, the indication information that the first cell needs to send the synchronization signal block, that is, the first cell decides the sending scheme of the synchronization signal block by itself, for example: the first cell decides the time-frequency position, sending period or number of sending times of the on-demand synchronization signal block by itself.

[0248] In some embodiments, switching to the first target state is performed based on the activation request information, and / or the synchronization signal block sending frequency is switched to the first target sending frequency.

[0249] Based on the activation request information, when the activation request message is "indication information that the first cell needs to switch to the first target state", the on state is the on state of the first cell, indicating that the first cell is sending synchronization signal blocks at the basic frequency; when the first cell is in a semi-dormant state, it limits data transmission and power consumption, and sends synchronization signal blocks at a transmission frequency lower than the basic frequency; when the first cell is in a dormant state, it temporarily stops sending synchronization signal blocks and minimizes power consumption, and switches the first cell to the first target state according to the type of the first target state.

[0250] Based on the activation request information, when the activation request message is "indication information that the first cell needs to switch the synchronization signal block transmission frequency to the first target transmission frequency", the synchronization signal block transmission frequency is the transmission frequency size when the first cell sends the synchronization signal block at a fixed period, and the first target transmission frequency is a fixed broadcast frequency configured by the network. For example: in the on state, the first cell can send an on-demand synchronization signal block every 10ms, and control the first cell to switch the synchronization signal block transmission frequency to the first target transmission frequency.

[0251] The first target state is an on state or a semi-dormant state; the first target transmission frequency is a third transmission frequency or a second transmission frequency. The third transmission frequency is greater than the second transmission frequency. The second transmission frequency may be a transmission frequency in a semi-dormant state, and the third transmission frequency is a higher transmission frequency. The third transmission frequency may also be a basic frequency or a corresponding transmission frequency in a normal on state.

[0252] In some embodiments, after receiving the activation request information, synchronization signal retransmission request information is received, and the synchronization signal retransmission request information is sent by the second cell; and a synchronization signal block is sent based on the synchronization signal retransmission request information.

[0253] It should be noted that if the first cell receives the on-demand synchronization signal block retransmission request information sent by the second cell, the first cell will send one or more on-demand synchronization signal blocks according to the retransmission request information configuration. The on-demand synchronization signal block retransmission request is a mechanism, for example: when the terminal device does not detect the synchronization signal block on the specified resource, or detects the synchronization signal block but fails to decode, it can request the base station (gNB, gNodeB) such as the base station corresponding to the second cell or the second cell to retransmit the synchronization signal block, and the second cell then sends the synchronization signal retransmission request information to the first cell.

[0254] The synchronization signal retransmission request information may include at least one of the following: indication information that the first cell needs to send a synchronization signal block on designated resources; indication information that the first cell needs to send a synchronization signal block.

[0255] First, the first cell needs to send indication information of the synchronization signal block on designated resources, where the designated resources refer to specific resource blocks allocated to the synchronization signal blocks in the frequency and time domains. These resource blocks are usually planned during network design to ensure that the synchronization signal blocks can be reliably broadcast and received.

[0256] Second, the first cell needs to send indication information of a synchronization signal block, wherein the need to send the synchronization signal block can be obtained from the synchronization signal retransmission request information, so as to send a specific synchronization signal block as required by the synchronization signal retransmission request information.

[0257] Furthermore, around the synchronization signal retransmission function, the time elapsed after sending the synchronization signal block is recorded to determine the first monitoring time; the first monitoring time is compared with the time threshold of the network configuration to obtain a first comparison result; based on the first comparison result, it is switched to the third target state, and / or the synchronization signal block sending frequency is switched to the third target sending frequency.

[0258] Among them, the first monitoring time is the time that elapses after the synchronization signal block is sent. Different functions can be performed according to the monitoring time, such as switching the first cell state or switching the synchronization signal block sending frequency to improve transmission efficiency. For example: if the activation request information sent by the second cell is received, the first cell will set a timer to record the time that elapses after sending the on-demand synchronization signal block, that is, the first monitoring time. If the first monitoring time is reached, it will switch to the on state and / or send the synchronization signal block according to the basic frequency.

[0259] Specifically, the third target state is a semi-sleep state, or a full sleep state; or the third target sending frequency is the second sending frequency, or the first sending frequency.

[0260] Among them, the first monitoring time is the time elapsed after the first cell sends a synchronization signal block. Different functions can be performed according to the monitoring time, such as switching the first cell state to a semi-sleep state, or a fully sleep state, or switching the synchronization signal block sending frequency to a second sending frequency, or the first sending frequency, so as to reduce the energy consumption of the first cell. The first sending frequency can be a sending frequency lower than the sending frequency corresponding to the semi-sleep state.

[0261] In a specific implementation, the monitoring time can be used to perform: setting a timer to record the time after sending the on-demand synchronization signal block and then switching to the on state and sending the synchronization signal block according to the basic frequency; or, if a period of time t at1 (t at1 >0) within which the first cell receives an on indication message sent by the second cell, wherein the indication message may include, for example: the first cell needs to remain on; or the first cell needs to be switched to an on state: switch to an on state; send a synchronization signal block according to the basic frequency, or, if a period of time t at1 If no activation indication information sent by the second cell is received within 10 days, the system switches to a fully dormant state or a semi-dormant state.

[0262] In addition, assuming that the first cell state is switched to the semi-dormant state after the monitoring time, the monitoring can continue for a period of time t at2 If no wake-up indication information sent by the second cell is received within 10 days, the system can switch to the full sleep state.

[0263] In some embodiments, after receiving the activation request information, the first cell receives wake-up indication information, which is sent by the second cell; switches to the second target state based on the wake-up indication information, and / or switches the synchronization signal block sending frequency to the second target sending frequency; and / or maintains the second target state based on the wake-up indication information, and / or keeps the synchronization signal block sending frequency at the second target sending frequency.

[0264] It should be noted that the wake-up indication information may be indication information for controlling the first cell to switch to the second target state. Switching to the second target state based on the wake-up indication information means switching the first cell to the second target state, wherein the second target state is an on state, a semi-dormant state, or a fully dormant state. For the specific switching process, this embodiment proposes the following scheme for illustration, for example: if a period of time t at2 (t at2 >0) within which the wake-up indication information sent by the second cell is received (referring to the wake-up indication information after receiving the activation request information). at2 The indication information may be used, for example, to indicate that the first cell needs to be switched to a semi-dormant state; or the first cell needs to be switched to an on state. The first cell switches to an on state; or switches to a semi-dormant state; on the other hand, if a period of time t at2 If the semi-dormant indication information sent by the second cell is not received within 10 seconds, the first cell can switch to the fully dormant state.

[0265] Furthermore, the wake-up indication information may also be indication information that the first cell needs to maintain the second target state. Maintaining the second target state based on the wake-up indication information means maintaining the first cell in the second target state, where the second target state is an on state, a semi-dormant state, or a fully dormant state. For example: if a period of time (t at2 >0) within which the wake-up indication information sent by the second cell is received (referring to the wake-up indication information after receiving the activation request information). at2 Within a period of time), the indication information may be used, for example, to: the first cell needs to maintain a semi-dormant state; on the other hand, if a period of time t at2 If no wake-up indication information sent by the second cell is received within 10 days, the system can switch to the full sleep state.

[0266] It should be noted that the wake-up indication information may also be indication information that the first cell needs to switch the synchronization signal block transmission frequency to the second target transmission frequency, that is, the synchronization signal block transmission frequency is switched to the second target transmission frequency according to the wake-up indication information. The second target transmission frequency is the first transmission frequency, or the second transmission frequency, or the third transmission frequency. For example: if the wake-up indication information sent by the second cell is received within a period of time, the indication information can be used to switch to the second target transmission frequency to send the synchronization signal block.

[0267] Furthermore, the wake-up indication information may also be indication information that the first cell needs to keep the synchronization signal block transmission frequency at the second target transmission frequency, that is, the synchronization signal block transmission frequency is maintained at the second target transmission frequency according to the wake-up indication information. The second target transmission frequency is the first transmission frequency, or the second transmission frequency, or the third transmission frequency. For example: if the wake-up indication information sent by the second cell is received within a period of time, the indication information may be used to maintain the second target transmission frequency for sending the synchronization signal block.

[0268] In some embodiments, after completing the reception of the wake-up indication information, a synchronization signal first indication information is received; and a synchronization signal block is sent based on the synchronization signal first indication information.

[0269] First, the first indication information of the synchronization signal may be indication information that the first cell needs to send a synchronization signal block on designated resources. The previous embodiment describes how to complete the switching of the operating state or the transmission frequency of the synchronization signal block after receiving the wake-up indication information, or how to maintain the current operating state or the transmission frequency of the synchronization signal block. The first indication information of the synchronization signal here is used to re-determine the transmission information of the synchronization signal block on the basis of the previous embodiment, that is, after the second cell is already in the second target state or has used the second transmission frequency. The synchronization signal block may be an additional non-periodic on-demand synchronization signal block that only lasts a few times. The first indication information of the synchronization signal may indicate that the first cell needs to send the indication information of the synchronization signal block on designated resources, wherein the designated resources refer to specific resource blocks allocated to the synchronization signal block in the frequency and time domains. These resource blocks are usually planned during network design to ensure that the synchronization signal block can be reliably broadcast and received.

[0270] Secondly, the first indication information of the synchronization signal may be indication information that the first cell needs to send a synchronization signal block, wherein the need to send the synchronization signal block may be obtained from the first indication information of the synchronization signal, and the second cell may select a synchronization signal block sending method and resource based on its own synchronization signal block configuration, and send the synchronization signal block. The synchronization signal block may be an additional non-periodic on-demand synchronization signal block that only lasts a few times.

[0271] In some embodiments, after receiving the wake-up indication information, a monitoring result is obtained, and the monitoring result includes the number of communication devices; based on the monitoring result, the state is switched to the fourth target state, and / or the synchronization signal block sending frequency is switched to the fourth target sending frequency.

[0272] The communication device is a communication device that needs to be served by the first cell. The communication device may be a user device or other terminal device. This embodiment is described by taking the communication device as an example.

[0273] In addition, the fourth target state may be an on state, a semi-sleep state, or a full sleep state; the fourth target transmission frequency may be the third transmission frequency, the second transmission frequency, or the first transmission frequency.

[0274] Specifically, after receiving the wake-up indication information, a monitoring result is obtained, and the monitoring result includes the number n of communication devices. UE The specific state switching process and frequency switching process may be, for example: if the number of communication devices to be served by the first cell is n UE Less than or equal to n off1 (n off1 >0): It is considered that there are almost no communication devices that need it to continue to provide services; and / or it enters a completely dormant state; the first cell in the completely dormant state will not actively send any signal or channel, but may receive specific signals or channels.

[0275] Optionally, after obtaining the monitoring result, if the number of communication devices n that need to be served by the first cell UE Less than or equal to n off1 (n off1 >0), and if the first cell is within a period of time t n (t n >0) within which no wake-up indication information including a keep-on indication is received from (possibly multiple) second cells: it is considered that almost no communication devices need it to continue to provide services; and / or it enters a completely dormant state.

[0276] For another example: if the number of communication devices that need to be served by the first cell is n UE Greater than or equal to n off1 , and is less than n off2 (0<n off1 <n off2 ): It is considered that only a small number of communication devices need it to continue to provide services; and / or enter a semi-dormant state (in this state, the synchronization signal block transmission frequency is lower than the basic frequency, for example: 1 / k of the basic frequency off1 (k off1 >1) or lower than the fundamental frequency f off1 (0<f off1 ) The semi-dormant state is an optional state. The basic frequency is the frequency at which the first cell sends a synchronization signal block in the on state, for example, the first cell can send a synchronization signal block every 10 mms in the on state.

[0277] Optionally, after obtaining the monitoring result, if the number of communication devices n that need to be served by the first cell UE Greater than or equal to n off1 , and is less than n off2 (0<n off1 <noff2 ), and if the first cell is within a period of time t n The wake-up indication information including the semi-dormant information indication is received from (possibly multiple) second cells: it is considered that only a small number of communication devices need it to continue to provide services; and / or enter the semi-dormant state; reduce the transmission frequency of the synchronization signal block to 1 / k of the basic frequency off1 ; or reduce the frequency of sending synchronization signal blocks by f off1 .

[0278] For another example: If the first cell is within a period of time t kn (t kn >t n ) within 12 hours, the wake-up indication information including the keep-on information indication is not received from (possibly multiple) second cells: it is considered that there are almost no communication devices that need it to continue to provide services; and / or it enters a completely dormant state.

[0279] In some embodiments, before receiving the activation request information, the first cell can also be configured. The specific configuration content is set by the second cell. The configuration information is used to control the function of the first cell, for example: the synchronization signal block structure configuration of the first cell, the synchronization signal block sending frequency, the resource information sent by the synchronization signal block, etc.

[0280] Specifically, before receiving the activation request information, first activation configuration information sent by the second cell is received, where the first activation configuration information is used to send activation configuration information and wake-up configuration information to the first cell.

[0281] The first activation configuration information includes at least one of the following: 1. The synchronization signal block resource configuration of the first cell, including the time-frequency resource information of the synchronization signal block of the first cell; 2. The synchronization signal block construction configuration information of the first cell; 3. The state configuration of the first cell, including the synchronization signal block sending period when the first cell is in different states, and / or the synchronization signal block sending frequency; 4. The service and / or coverage area information of the first cell.

[0282] In a specific implementation, the configuration process of the configuration information may, for example: initialize the sleep / start process configuration of the first cell, such as: the on-demand synchronization signal block configuration of the first cell, including the on-demand synchronization signal block time and frequency resource information; the state configuration of the first cell, including the synchronization signal block sending period / frequency when the first cell is in different states; the location information of the first cell or the base station to which the first cell belongs; the service / coverage area information of the first cell.

[0283] The synchronization signal block construction configuration information of the first cell includes at least one of the following items: 1. The signal block includes the primary synchronization signal and the secondary synchronization signal or other signals with a synchronization function, and does not include a broadcast physical channel and a demodulation reference signal of a broadcast physical channel; 2. The signal block includes the primary synchronization signal and the secondary synchronization signal or other signals with a synchronization function, and includes a demodulation reference signal of a broadcast physical channel or other signals with a measurement function; 3. Or the signal block includes all components in a general synchronization signal block, namely, the primary synchronization signal, the secondary synchronization signal, the broadcast physical channel and the demodulation reference signal of the broadcast physical channel.

[0284] Further, by setting the construction configuration information of the synchronization signal block, the construction adjustment of the synchronization signal block can be achieved, for example: the construction configuration information of the on-demand synchronization signal block of the first cell may include, for example: the on-demand synchronization signal block includes the primary and secondary synchronization signals (PSS / SSS) or other signals with synchronization function, and does not include PBCH and its DMRS; or the on-demand synchronization signal block includes the primary and secondary synchronization signals (PSS / SSS) or other signals with synchronization function, and includes the demodulation reference signal (DMRS) of PBCH or other signals with measurement function; or the on-demand synchronization signal block includes all components in the general synchronization signal block, namely the primary and secondary synchronization signals (PSS / SSS), PBCH and its demodulation reference signal (DMRS). The state configuration of the first cell includes the synchronization signal block transmission period / frequency when the first cell is in different states; the service / coverage area information of the first cell.

[0285] In combination with the above embodiments, a complete first cell control process is proposed, referring to Figure 2 , Figure 2 In the example, the first cell is SCell, the second cell is PCell, and the communication device is UE. First, the first cell performs device configuration according to the configuration information related to the state switching generated by the second cell. In Step 1, the state switching condition is judged according to the configuration information to perform state switching. If an activation request message is received, it switches to the corresponding state according to the activation request message, and then completes the sending of one or more synchronization signal blocks according to the indication information in the activation request message. For example, in Step 6, if the second indication information of the on-demand synchronization signal block sent by the second cell is received, the first cell sends one or more on-demand synchronization signal blocks according to the indication information.

[0286] like Figure 4, assuming that in the measurement function such as Step 6, if the first cell receives the wake-up indication information, and the wake-up indication information includes the start indication information: switch to the start state and send the synchronization signal block according to the basic frequency. Or, if the wake-up indication information includes the semi-sleep indication information: switch to the semi-sleep state; and send the synchronization signal block according to the second sending frequency.

[0287] This embodiment receives activation request information, which is sent by the second cell, which is a network device; and sends one or more synchronization signal blocks. It is realized that the network device controls the sending of synchronization signal blocks through the activation request information, and sends, for example, on-demand synchronization signal blocks, to ensure that the network device sends on-demand synchronization signal blocks only when there is a demand (the demand may be indicated by the second cell or the communication device), so as to save energy consumption while ensuring the signal synchronization function.

[0288] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 3 The implementation subject of the steps of this embodiment is the second cell, and the communication method further includes:

[0289] Step S201: Send activation request information to the first cell.

[0290] It should be noted that the executor of this embodiment is the second cell, and the second cell may be a PCell (Primary Cell). PCell refers to a base station cell that establishes a connection and main communication between a user device (communication device) and a network. PCell is an important concept in mobile communication technologies (such as LTE and 5G NR); the second cell may also be a base station corresponding to the PCell.

[0291] When the network decides that an SCell (first cell) can be activated, the core network or the second cell (PCell) will send an activation request message to the auxiliary cell. After the SCell is prepared, the second cell network needs to notify the user equipment (communication equipment) to activate the corresponding first cell, for example: receiving the synchronization signal block corresponding to the first cell.

[0292] In some embodiments, the activation request information may include at least one of the following:

[0293] 1. Indication information that the first cell needs to switch to a first target state, where the first target state is an on state or a semi-dormant state, wherein the on state or the semi-dormant state is the state in which the second cell indicates that the first cell needs to be switched, wherein the state of the first cell includes an on state, a semi-dormant state and a dormant state, wherein when the first cell is in the on state, the first cell sends a synchronization signal block at a basic frequency; when the first cell is in the semi-dormant state, it limits data transmission and power consumption, and sends synchronization signal blocks at a transmission frequency lower than the basic frequency; when the first cell is in the dormant state, it temporarily stops sending synchronization signal blocks and minimizes power consumption.

[0294] 2. Indication information that the first cell needs to switch the synchronization signal block transmission frequency to the first target transmission frequency. The synchronization signal block transmission frequency is the transmission frequency size when the first cell periodically sends the synchronization signal block. The first target transmission frequency is a fixed broadcast frequency configured by the network. For example: in the on state, the first cell can send an on-demand synchronization signal block every 10ms.

[0295] 3. The first cell needs to send indication information of a synchronization signal block on designated resources, where designated resources refer to specific resource blocks allocated to the synchronization signal block in the frequency and time domains, which are usually planned during network design to ensure that the synchronization signal block can be reliably broadcast and received. The synchronization signal block may be an on-demand synchronization signal block.

[0296] 4. The indication information that the first cell needs to send the synchronization signal block, i.e., the first cell is informed of the need to send the synchronization signal block, and the first cell decides by itself how and on which resources to send the synchronization signal block.

[0297] Step S202: Send activation indication information to the communication device.

[0298] It should be noted that if Figure 2 , Figure 4 or Figure 5As shown in step 2, in order for the communication device to successfully correspond to the synchronization signal block sent by the first cell, after sending an activation request message to the first cell to activate / turn on / control the synchronization signal block, it is also necessary to send an activation indication message to the communication device to ensure that the communication device can interact with the synchronization signal block sent by the first cell. For example: if the first cell activation indication message of the network is received, wherein the activation indication message can be transmitted through the backhaul port, the content of the activation indication message may include, for example: instructing a designated first cell to provide services for the communication device. The second cell will send the first cell activation indication message to the communication device, wherein the indication message may include, for example: the first cell ID that can be activated and the on-demand synchronization signal block configuration of the first cell. An activation request message is sent to the first cell, wherein the content of the request message is as described above.

[0299] Optional, Figure 3 There may be no order requirement between the two operations in Step 2. The same applies to subsequent similar operations, that is, when the second cell needs to send instruction / request information to the communication device and the first cell, there may be no order requirement for the sending operation.

[0300] The activation indication information sent to the communication device may include at least one of the following:

[0301] 1. Identity information of the first cell that can be activated, for example: Physical Cell Identity (PCI): used to distinguish different cells, or Cell ID: a higher-level identifier used to uniquely identify a cell.

[0302] 2. The operating status of the first cell that can be activated, for example, whether the cell is in a completely dormant state.

[0303] 3. The synchronization signal block sending frequency of the first cell that can be activated, for example: the synchronization signal block sending interval, the synchronization signal block configuration index, etc.

[0304] 4. The synchronization signal block configuration of the first cell that can be activated, for example: the frequency and time resources of the synchronization signal block of the first cell that can be activated, and the communication device can receive the synchronization signal block based on the configuration.

[0305] 5. The synchronization signal block retransmission configuration of the first cell that can be activated, for example: the retransmission configuration determines the retransmission timeout threshold, that is, if the UE fails to successfully detect the synchronization signal block of the first cell within a specified time after receiving the activation indication information, retransmission is required. The retransmission method can be based on the rest of the retransmission configuration, including the uplink time and frequency resources required for retransmission.

[0306] In some embodiments, after sending activation indication information to the communication device, the second cell detects and receives synchronization signal retransmission report information sent by the communication device; sends synchronization signal retransmission request information to the first cell based on the synchronization signal retransmission report information; and sends synchronization signal retransmission indication information to the communication device based on the synchronization signal retransmission report information. The synchronization signal retransmission report information includes at least one of the following: identity information of the first cell corresponding to the synchronization signal block that needs to be retransmitted.

[0307] It should be noted that the current embodiment is used to illustrate that when a synchronization signal retransmission demand occurs, when the synchronization signal retransmission report information sent by the communication device is received, it indicates that the communication device has certain communication problems, such as: synchronization failure or timeout, etc. For example, the communication device may set a timeout timer, and when the synchronization signal block is not successfully received within the specified time, a retransmission request will be triggered. This ensures that even if the initial reception fails, the communication device still has a chance to retry to receive the synchronization signal block.

[0308] Furthermore, in a specific implementation, Figure 5 As shown in Step 5, when receiving the synchronization signal retransmission report information sent by the communication device, the second cell will send a synchronization signal retransmission request information to the first cell according to the synchronization signal retransmission report information, and send a synchronization signal retransmission indication information to the communication device based on the synchronization signal retransmission report information; for example: if the on-demand synchronization signal block retransmission request information sent by the communication device is received, the second cell will send an on-demand synchronization signal block retransmission request information to the first cell, wherein the request information is used to request the first cell to send an on-demand synchronization signal block on designated resources, or to request the first cell to send an on-demand synchronization signal block; the second cell will send an on-demand synchronization signal block retransmission indication information to the communication device, wherein the indication information may include, for example: the on-demand synchronization signal block configuration of the first cell, the identity information of the first cell.

[0309] Optionally, in some embodiments, after receiving the synchronization signal retransmission report information sent by the communication device, the second cell sets a retransmission timer to record the time elapsed after receiving the synchronization signal retransmission report information, and determines a second monitoring time; sends a synchronization signal retransmission request information to the first cell based on the second monitoring time; and sends a synchronization signal retransmission indication information to the communication device based on the second monitoring time.

[0310] The synchronization signal retransmission request information may include at least one of the following: indication information that the first cell needs to send a synchronization signal block on designated resources; indication information that the first cell needs to send a synchronization signal block.

[0311] It should be noted that the time after the retransmission timer is set to record the time after receiving the synchronization signal retransmission report information is the second monitoring time. The second monitoring time is determined to provide a differentiated function for the retransmission function according to the duration after receiving the request.

[0312] First, according to the second monitoring time, synchronization signal retransmission request information is sent to the first cell. Specifically, the second monitoring time is compared with the monitoring time threshold configured by the network to obtain a second comparison result; the number of retransmission requests received within the second monitoring time is compared with the number threshold configured by the network to obtain a third comparison result; based on the second comparison result and the third comparison result, synchronization signal retransmission request information is sent to the first cell. For example, if the time after receiving the retransmission request information is less than or equal to t req (t req >0): If k req (k req >0) request information: sending on-demand synchronization signal block retransmission request information to the first cell, wherein the request information is used to request the first cell to send on-demand synchronization signal blocks on designated resources, or, to request the first cell to send on-demand synchronization signal blocks; or, sending on-demand synchronization signal block retransmission request information to the first cell, wherein the request information is used to request the first cell to send on-demand synchronization signal blocks on designated resources, or, to request the first cell to send on-demand synchronization signal blocks; optionally, after sending the retransmission request information, the second cell may reset the retransmission timer.

[0313] Secondly, the synchronization signal retransmission indication information is sent to the communication device, specifically: the second monitoring time is compared with the monitoring time threshold configured by the network to obtain a second comparison result; the number of retransmission requests received within the second monitoring time is compared with the number threshold configured by the network to obtain a third comparison result; based on the second comparison result and the third comparison result, the synchronization signal retransmission indication information is sent to the communication device. For example: if the time after receiving the retransmission request information is less than or equal to t req (t req >0): If k req (k req >0) request information: send on-demand synchronization signal block retransmission indication information to the communication device, where the indication information may include, for example: on-demand synchronization signal block configuration of the first cell. Or, if the time after receiving the retransmission request information is greater than or equal to t req : Sending on-demand synchronization signal block retransmission indication information to the communication device, wherein the indication information may include, for example: the on-demand synchronization signal block configuration of the first cell; optionally, after sending the retransmission indication information, the second cell may reset the retransmission timer.

[0314] In some embodiments, the second cell receives wake-up request information sent by the communication device; and sends wake-up indication information to the first cell based on the wake-up request information.

[0315] The wake-up request information includes at least one of the following: identity information of the first cell that the communication device needs to wake up; measurement results of the synchronization signal block of the first cell that needs to be woken up by the communication device; and location information of the communication device. The wake-up indication information includes at least one of the following: indication information that the first cell needs to maintain the second target state; indication information that the first cell needs to switch to the second target state; indication information that the first cell needs to keep the synchronization signal block sending frequency at the second target sending frequency; indication information that the first cell needs to switch the synchronization signal block sending frequency to the second target sending frequency.

[0316] Among them, in the indication information that the first cell needs to switch to the second target state, the second target state is an on state, a semi-dormant state, or a fully dormant state.

[0317] It should be noted that the second cell receives the wake-up request information sent by the communication device; and the step of sending the wake-up indication information to the first cell based on the wake-up request information can be specifically as follows: Figure 4 In the process of Step 4 to Step 6, specifically, for example: Optionally, when the second cell receives the wake-up request information of the communication device, the comparison result of the second cell between the location information of the communication device and the coverage range of the first cell meets the range condition of the service provided by the first cell, such as: the distance between the communication device and the first cell or its base station is less than or equal to a certain distance threshold: if a period of time t after receiving the wake-up request information con (t con >0) received k atv (k atv >0) request information; optionally, and based on the measurement report information in the wake-up request information, selecting a suitable first cell: sending wake-up indication information to the first cell, the wake-up indication information including at least one of the following: indication information that the first cell needs to maintain the second target state; indication information that the first cell needs to switch to the second target state; indication information that the first cell needs to keep the synchronization signal block sending frequency at the second target sending frequency; indication information that the first cell needs to switch the synchronization signal block sending frequency to the second target sending frequency. For example: if within a period of time t con Within, the second cell receives a total of k hatv (0<k hatv <k atv ) request information, it can enable the first cell to switch to a semi-dormant state or maintain a semi-dormant state, and the wake-up request information may include semi-dormant indication information.

[0318] In some embodiments, the second cell receives synchronization request information after sending wake-up indication information to the first cell, and the synchronization request information may be sent by the network or the communication device; based on the synchronization request information, the first indication information of the synchronization signal is sent to the first cell; and based on the synchronization request information, the second indication information of the synchronization signal is sent to the communication device.

[0319] At this time, the first indication information of the synchronization signal includes at least one of the following:

[0320] 1. The first cell needs to send indication information of a synchronization signal block on designated resources. Designated resources refer to specific resource blocks allocated to synchronization signal blocks in the frequency and time domains. These resource blocks are usually planned during network design to ensure that the synchronization signal blocks can be reliably broadcast and received. The synchronization signal block can be an on-demand synchronization signal block.

[0321] 2. The first cell needs to send the indication information of the synchronization signal block, that is, the first cell is informed of the need to send the synchronization signal block, and the first cell decides by itself how and on which resources to send the synchronization signal block.

[0322] In addition, the second indication information of the synchronization signal includes at least one of the following: identity information of the first cell; and synchronization signal block configuration of the first cell. The identity information of the first cell is identification information of the first cell, which is used to determine the identity of the first cell, and the synchronization signal block configuration is signal block configuration information, which is used to help the communication device detect the synchronization signal block.

[0323] In some embodiments, the second cell receives measurement request information after sending wake-up indication information to the first cell, and the measurement request information may be sent by the network or the communication device; sends synchronization signal first indication information to the first cell based on the measurement request information; and sends synchronization signal second indication information to the communication device based on the measurement request information.

[0324] It should be noted that the measurement request information is the measurement requirement information of the communication device, and the contents of the first indication information of the synchronization signal and the second indication information of the synchronization signal are consistent with the first indication information and the second indication information of the synchronization signal in the above embodiment.

[0325] Specifically, the post-awakening interaction process of the first cell is as follows: Figure 2 As shown in Step 5, when the second cell knows that the communication device has a measurement requirement (such as RRM measurement) for the first cell: if the second cell determines that the first cell needs to send an on-demand synchronization signal block at this time: if the on-demand synchronization signal block of the first cell has a measurement function: then the first indication information of the on-demand synchronization signal block is sent to the communication device, and the second indication information of the on-demand synchronization signal block is sent to the first cell.

[0326] This embodiment describes the activation configuration process of the first cell. In some embodiments, before sending activation request information to the first cell, the second cell may send first activation configuration information to the first cell, and the first activation configuration information is used to send activation configuration information and wake-up configuration information to the first cell. The first activation configuration information is used to send activation configuration information and wake-up configuration information to the first cell.

[0327] Among them, the first activation configuration information includes at least one of the following: 1. The synchronization signal block resource configuration of the first cell, including the time-frequency resource information of the synchronization signal block of the first cell; 2. The synchronization signal block construction configuration information of the first cell; 3. The state configuration of the first cell, including the synchronization signal block sending period when the first cell is in different states, and / or the synchronization signal block sending frequency; 4. The service and / or coverage area information of the first cell.

[0328] In a specific implementation, the first activation configuration information may refer to Figure 2 , Figure 4 as well as Figure 5 As shown in Step 0-1 or Step 0-2, the first activation configuration information may be, for example: initializing the sleep / start process configuration of the first cell, such as: the on-demand synchronization signal block configuration of the first cell, including the on-demand synchronization signal block time and frequency resource information; the state configuration of the first cell, including the synchronization signal block sending period / frequency when the first cell is in different states; the location information of the first cell or the base station to which the first cell belongs; the service / coverage area information of the first cell.

[0329] In addition, the synchronization signal block construction configuration information of the first cell includes at least one of the following items: 1. The signal block includes the primary synchronization signal and the secondary synchronization signal or other signals with a synchronization function, and does not include a broadcast physical channel and a demodulation reference signal of a broadcast physical channel; 2. The signal block includes the primary synchronization signal and the secondary synchronization signal or other signals with a synchronization function, and includes a demodulation reference signal of a broadcast physical channel or other signals with a measurement function; 3. Or the signal block includes all components in a general synchronization signal block, namely, the primary synchronization signal, the secondary synchronization signal, the broadcast physical channel and the demodulation reference signal of the broadcast physical channel.

[0330] In the specific implementation, the synchronization signal block configuration information can refer to Figure 2 , Figure 4 as well as Figure 5As shown in Step 0-1 or Step 0-2 in, by setting the construction configuration information of the synchronization signal block, the construction adjustment of the synchronization signal block can be achieved, for example: the on-demand synchronization signal block construction configuration information of the first cell may include, for example: the on-demand synchronization signal block includes the primary and secondary synchronization signals (PSS / SSS) or other signals with synchronization function, and does not include PBCH and its DMRS; or the on-demand synchronization signal block includes the primary and secondary synchronization signals (PSS / SSS) or other signals with synchronization function, and includes the demodulation reference signal (DMRS) of PBCH or other signals with measurement function; or the on-demand synchronization signal block includes all components in the general synchronization signal block, namely the primary and secondary synchronization signals (PSS / SSS), PBCH and its demodulation reference signal (DMRS). The state configuration of the first cell includes the synchronization signal block transmission period / frequency when the first cell is in different states; the service / coverage area information of the first cell.

[0331] In some embodiments, before sending activation indication information to the communication device, the second cell sends second activation configuration information to the communication device, where the second activation configuration information is used to send activation configuration information and wake-up configuration information to the communication device.

[0332] The second activation configuration information includes at least one of the following: the synchronization signal block configuration of the first cell, including the time-frequency resource information of the synchronization signal block of the first cell; the state configuration of the first cell, including the synchronization signal block transmission period when the first cell is in different states, and / or the synchronization signal block transmission frequency; the location information of the first cell or the base station to which the first cell belongs; the synchronization signal block retransmission configuration information of the first cell; the service / coverage area information of the first cell. The time-frequency resources allow the communication device to accurately match the signal block sent by the corresponding first cell, and the communication device obtains the frequency or period to better detect the synchronization signal block of the first cell. The location information and service / coverage area information of the base station can assist the communication device in confirming whether the cell to be matched or matched is the cell that is most suitable for the communication device, and the retransmission configuration information is to better serve the subsequent retransmission service between the communication device and the first cell.

[0333] In combination with the above embodiments, a complete second cell control process is proposed, refer to Figure 2 , Figure 2In the example, the case where the first cell is SCell, the second cell is PCell, and the communication device is U is used for explanation. First, the first cell performs device configuration according to the configuration information related to the state switching generated by the second cell. In Step 1, the state switching condition is determined according to the configuration information, and the state switching is performed. If the activation request information is received, the corresponding state is switched according to the activation request information, and then the synchronization signal block is sent once or multiple times according to the indication information in the activation request information. In Step 2, after receiving the activation indication information of the first cell on the network side, the activation indication information and the activation request information are sent to the communication device and the first cell respectively, so that the first cell broadcasts the synchronization signal block, and the communication device synchronizes according to the synchronization signal block and the first cell activation indication information given by the second cell to complete the connection. In Step 5, if the communication device issues other requirements such as measurement, the second cell sends the first indication information and the second indication information to the communication device and the first cell end, so that the first cell end sends the corresponding synchronization signal block, and the communication device detects and realizes the target function according to the first indication information and the corresponding synchronization signal block. For example: Figure 5 In Step 5, if the first cell is in a semi-dormant state or an on state or the first cell is in a semi-dormant state, if a synchronization request message sent by a communication device is received, a first indication message of an on-demand synchronization signal block is sent to the communication device, wherein the first indication message may include, for example: indication message that the communication device needs to be synchronized through an on-demand synchronization signal block, and / or on-demand synchronization signal block configuration information of the first cell. A second indication message of an on-demand synchronization signal block is sent to the first cell, wherein the second indication message is used to instruct the first cell to send an on-demand synchronization signal block on a specified resource, or to instruct the first cell to send an on-demand synchronization signal block.

[0334] As in Step 6, if the first cell receives the second indication information of the on-demand synchronization signal block sent by the second cell, the first cell sends one or more on-demand synchronization signal blocks according to the indication information.

[0335] like Figure 4 , assuming that in the measurement function such as Step 6, if the first cell receives the on indication information: switch to the on state and send the synchronization signal block according to the basic frequency. Or, if the first cell receives the semi-sleep indication information: switch to the semi-sleep state; and send the synchronization signal block according to the frequency in the semi-sleep state.

[0336] Based on the first and second embodiments of the present application, in the third embodiment of the present application, the same or similar contents as those of the first and second embodiments can be referred to the above description, and will not be described in detail later. Figure 6 The steps of this embodiment are implemented by a communication device, and the communication method further includes:

[0337] Step S301: receiving activation indication information sent by the second cell.

[0338] It should be noted that the execution subject of this embodiment is a communication device, which may be a UE (User Equipment).

[0339] It is understandable that the activation instruction information may include at least one of the following:

[0340] 1. Identity information of the first cell that can be activated, for example: Physical Cell Identity (PCI): used to distinguish different cells, or Cell ID: a higher-level identifier used to uniquely identify a cell.

[0341] 2. The operating status of the first cell that can be activated, for example, whether the cell is in a completely dormant state.

[0342] 3. The synchronization signal block sending frequency of the first cell that can be activated, for example: the synchronization signal block sending interval, the synchronization signal block configuration index, etc.

[0343] 4. The synchronization signal block configuration of the first cell that can be activated, for example: the frequency and time resources of the synchronization signal block of the first cell that can be activated, and the communication device can receive the synchronization signal block based on the configuration.

[0344] 5. The synchronization signal block retransmission configuration of the first cell that can be activated, for example: the retransmission configuration determines the retransmission timeout threshold, that is, if the UE fails to successfully detect the synchronization signal block of the first cell within a specified time after receiving the activation indication information, retransmission is required. The retransmission method can be based on the rest of the retransmission configuration, including the uplink time and frequency resources required for retransmission.

[0345] Step S302: Setting the first cell to an activated state based on the activation indication information.

[0346] It should be noted that the first cell is set to an activated state based on the activation indication information, and the activated state is the state of a secondary cell that can provide data transmission services for the UE in a carrier aggregation scenario.

[0347] In some embodiments, after receiving the activation indication information sent by the second cell, the communication device detects the synchronization signal block sent by the first cell based on the activation indication information, and the synchronization signal block may be an on-demand synchronization signal block, that is, a synchronization signal block sent by the first cell that is non-periodic and can be used to perform a specific function. The synchronization signal block of a specific function is, for example, a synchronization or measurement function.

[0348] It should be noted that the synchronization signal block is the default synchronization signal block, and the on-demand synchronization signal block is the synchronization signal block sent from the first cell according to the corresponding needs of the communication device, which corresponds to the required function, such as measurement. The on-demand synchronization signal block, that is, the synchronization signal block sent by the first cell is non-periodic and can be used to perform specific functions. The synchronization signal block of specific functions, such as synchronization or measurement functions, etc. In some embodiments, assuming that the activation indication information is to realize the synchronization function, the time and frequency synchronization is performed with the first cell based on the synchronization signal block of the first cell. For example Figure 2 As shown, the activation request information in Step 2 makes the synchronization signal block sent in Step 3 the synchronization signal block, and in Step 5, if the communication device has a corresponding demand, the second indication information can be sent by the second cell to the first cell. At this time, the synchronization signal block sent by the first cell in Step 6 is the on-demand synchronization signal block.

[0349] In some embodiments, a retransmission process can be set, that is, a timer is set to record the time after receiving the activation indication information to obtain a third monitoring time; the synchronization signal block retransmission configuration information is extracted from the activation indication information; the third monitoring time and the retransmission configuration information are compared to obtain a fourth comparison result.

[0350] It should be noted that the third monitoring time is the time after recording the activation indication information, extracting the synchronization signal block retransmission configuration information from the activation indication information, and comparing the third monitoring time with the retransmission configuration information to determine whether the synchronization signal block is not detected within the configuration time, so that the retransmission process needs to be started. Figure 5 As shown, in Step 4, if the synchronization signal block is not received for a period of time, it means that the function cannot be further realized and it is necessary to further send the synchronization signal block retransmission request information. As shown in Step 5, the second cell sends information to both parties based on the synchronization signal block retransmission request information to facilitate the two ends to realize the function through the synchronization signal block.

[0351] Further, the specific retransmission decision process may be to compare the number of synchronization signal blocks of the first cell received within the third monitoring time with the retransmission configuration information to obtain a fifth comparison result; and send synchronization signal retransmission report information to the second cell based on the fourth comparison result and the fifth comparison result. The synchronization signal retransmission report information includes at least one of the following: identity information of the first cell corresponding to the synchronization signal block that needs to be retransmitted.

[0352] Further, the number of synchronization signal blocks of the first cell received within the third monitoring time is compared with the retransmission configuration information, and the comparison result is the fifth comparison result. Based on the fourth comparison result, that is, when the third monitoring time exceeds a certain threshold and the number of synchronization signal blocks received from the first cell is less than a certain threshold, it is determined that there is a retransmission demand, and synchronization signal retransmission report information is sent to the second cell. Among them, the first cell corresponding to the synchronization signal block that needs to be retransmitted is the first cell to connect to the retransmission service. The specific process is as follows: Figure 5 As shown, for example: Step 4, if the first cell activation indication information sent by the second cell is received, if the activation indication information includes the first cell state switching information: synchronize based on the synchronization signal block sent by the first cell; if the activation indication information includes the indication information of the on-demand synchronization signal block, wherein the indication information may include, for example: the indication information that the communication device needs to synchronize through the on-demand synchronization signal block and the on-demand synchronization signal block configuration information of the first cell: set a timer to record the time (third monitoring time) after receiving the activation indication information; detect the on-demand synchronization signal block sent by the first cell based on the indication information sent by the second cell; if a period of time t od (t od >0) The number of synchronization signal blocks successfully detected within the time threshold is greater than or equal to n od (n od >0) number threshold: it is considered that the on-demand synchronization signal block sent by the first cell has been received; and / or synchronization is performed through the on-demand synchronization signal block; measurement is performed through the on-demand synchronization signal block. For example: if a period of time t od The number of synchronization signal blocks successfully detected within is less than n od Second: consider that the on-demand synchronization signal block sent by the first cell is not received; send an on-demand synchronization signal block retransmission request message to the second cell and perform a retransmission operation.

[0353] Among them, if the activation indication information does not include indication information of the on-demand synchronization signal block: then the communication device is synchronized based on the synchronization signal block sent by the first cell.

[0354] In a specific implementation, assuming that the retransmission step is entered, the following can be done, for example Figure 5 As shown: in Step 7, if the on-demand synchronization signal block retransmission indication information sent by the second cell is received, the communication device will detect the on-demand synchronization signal block sent by the first cell based on the configuration information sent by the second cell; od (t od >0) the number of synchronization signal blocks detected is greater than or equal to n od (n od >0) times: it is considered that the on-demand synchronization signal block sent by the first cell has been received; and / or synchronization is performed through the on-demand synchronization signal block. Or, if for a period of time t odThe number of synchronization signal blocks detected within is less than n od (n od >0) times: it is considered that the on-demand synchronization signal block sent by the first cell is not received; and / or the on-demand synchronization signal block retransmission request continues to be sent to the second cell, and the subsequent process will start from step 5 of the retransmission process.

[0355] In some embodiments, after detecting the synchronization signal block sent by the first cell, the communication device compares the measurement result of the synchronization signal block with the activation indication information sent by the second cell to generate a sixth comparison result; compares the current location information of the communication device with the activation indication information sent by the second cell to generate a seventh comparison result; and sends a wake-up request message to the second cell based on the sixth comparison result and the seventh comparison result.

[0356] It should be noted that before comparing the measurement result of the synchronization signal block with the activation indication information sent by the second cell, the measurement result needs to be described. This embodiment proposes a device measurement process, such as Figure 4 The steps in Step 4, the measurement process is, for example: Step 4, if the first cell activation indication information sent by the second cell is received, after receiving the synchronization signal block for measurement, the communication device will perform measurement through the on-demand synchronization signal block: Ms, Ocs and other parameters can be obtained from the activation indication information sent by the second cell, and then the measurement result is combined with each parameter to complete the comparison to obtain the sixth comparison result, that is, if Mn+Ocn-Hys>Ms+Ocs+Off, where Mn is the measurement result of the first cell (such as RSRP, RSRQ, SINR, RSCP or EcN0 of the reference signal). Optionally, Mn can also be the measurement result of the first cell without considering any bias. Hys is a hysteresis parameter, for example: this value can be configured by reportConfigNR. Ms is the measurement result of the second cell. Optionally, Ms can also be the measurement result of the second cell without considering any bias. Ocn is a cell-specific bias parameter of the first cell, for example: this value can be configured by cellIndividualOffset in measObjectNR. Ocs is the cell-specific offset parameter of the second cell, for example: This value can be configured by reportConfigNR in measObjectNR. off is the offset parameter, for example: This value can be configured by reportConfigNR; or, if Mn–Hys>Ms+Ost, where Ost is the event offset parameter, for example: This value can be configured by reportConfigNR; or, if Mn–Hys>Ms; or, if Mn>Ms;

[0357] In addition, optionally, Thresh1 can be obtained from the activation indication information sent by the second cell, and then Thresh1 is compared with Mls to obtain the seventh comparison result. If Mls + Hys1 < Thresh1, where Mls is the distance between the communication device and the reference location. The reference location can be the location of the first cell or its affiliated base station. For example, this value can be configured by reportConfigNR. Optionally, Mls can also be the distance between the communication device and the reference location without considering any bias. Hys1 is a hysteresis parameter. For example, this value can be configured by reportConfigNR. Thresh1 is the first threshold. For example, this value can be configured by reportConfigNR; or, if Mls < Thresh1;

[0358] Furthermore, if Ms + Hys2 < Thresh2, where Ms is the measurement result of the second cell. Optionally, Mn can also be the measurement result of the first cell without considering any bias. Hys2 is a hysteresis parameter. For example, this value can be configured by reportConfigNR. Thresh2 is the second threshold. For example, this value can be configured by reportConfigNR;

[0359] Among them, if Ms < Thresh2: it is considered that the second cell needs to indicate the first cell to perform a state switch; and / or send a first cell wake-up request message to the second cell; and report its own location information to the second cell.

[0360] It can be understood that the wake-up request message includes at least one of the following: the identity information of the first cell to be woken up; the measurement result of the synchronization signal block of the first cell to be woken up by the communication device; the location information of the communication device.

[0361] Among them, the identity information of the first cell refers to the unique identifier or identity code of the first cell, which is used to identify and distinguish different communication devices. The identity information can be a number, a string, or other forms of identifiers. The measurement result of the synchronization signal block of the first cell by the communication device. The communication device may determine whether to wake up the first cell by measuring the parameters of the synchronization signal block of the first cell received (such as power, time delay, etc.). The location information of the communication device, that is, the measured location, is used to determine the distance and location relationship between the communication device and the first cell.

[0362] In some embodiments, before receiving the activation indication information sent by the second cell, the communication device receives the second activation configuration information sent by the second cell, and the second activation configuration information is used to send activation configuration information and wake-up configuration information to the communication device.

[0363] Among them, the second activation configuration information includes at least one of the following: the synchronization signal block configuration of the first cell, including the time-frequency resource information of the synchronization signal block of the first cell; the state configuration of the first cell, including the synchronization signal block transmission period when the first cell is in different states, and / or the synchronization signal block transmission frequency; the location information of the first cell or the base station to which the first cell belongs; the synchronization signal block retransmission configuration information of the first cell; the service / coverage area information of the first cell. The time-frequency resources allow the communication device to accurately match the signal block sent by the corresponding first cell, and the communication device obtains the frequency or period to better detect the synchronization signal block of the first cell. The location information and service / coverage area information of the base station can assist the communication device in confirming whether the cell to be matched or matched is the cell that is most suitable for the communication device, and the retransmission configuration information is to better serve the subsequent retransmission service between the communication device and the first cell.

[0364] In some embodiments, to achieve different functions, the communication device may send synchronization request information to the second cell after sending the wake-up request information to the second cell; or, after sending the wake-up request information to the second cell, send measurement request information to the second cell. For example: if the first indication information of the on-demand synchronization signal block sent by the second cell is received, the communication device detects the on-demand synchronization signal block sent by the first cell based on the indication information sent by the second cell; synchronizes through the on-demand synchronization signal block; or measures through the on-demand synchronization signal block.

[0365] In some embodiments, after sending synchronization request information to the second cell, or sending measurement request information to the second cell, the communication device also receives second indication information of a synchronization signal sent by the second cell; and detects the synchronization signal block sent by the first cell based on the second indication information of the synchronization signal.

[0366] The second indication information of the synchronization signal includes at least one of the following: identity information of the first cell; and synchronization signal block configuration of the first cell. The identity information of the first cell is identification information of the first cell, which is used to determine the identity of the first cell, and the synchronization signal block configuration is signal block configuration information, which is used to help the communication device detect the synchronization signal block.
