Description

Technical Field

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

[0281] The embodiment of the present invention provides a communication method, referring to Figure 2 , Figure 2 The figure is a flow chart of a first embodiment of a communication method of the present invention.

[0282] In this embodiment, the communication method is applied to the first cell;

[0283] The communication method comprises the following steps:

[0284] Step S10: receiving an activation measurement report sent by a communication terminal device.

[0285] It should be noted that the execution subject of this embodiment may be a communication device (or other device that can achieve the same or similar functions) operating as a first cell in a network environment, and the first cell may be a primary cell (Primary Cell, PCell, also referred to as a primary service cell) in a 5G communication network environment, or a base station to which the primary cell belongs. In this embodiment and the following embodiments, the communication method of this embodiment is described by taking the first cell as an example.

[0286] In practical applications, time domain technology (UE wake up signal (WUS) for gNB / on-demand SSB / SIB1): Time domain energy saving technology can improve system energy efficiency by adjusting the duration of general events or periodic event periods on the network side / network (or base station) side. Common time domain energy saving technologies include discontinuous transmission (DTX) / discontinuous reception (DRX); adjusting the general signal / channel period; adjusting the UE special signal / channel period; designing on-demand SSB / SIB1; designing dynamic cell sleep / wake-up processes, etc.

[0287] Among them, the current standard supports SSB / SIB1-less operation in intra-band carrier aggregation (CA) scenarios, and communication terminal devices that need to be served by secondary cells can be synchronized through the primary cell. For non-carrier aggregation scenarios, communication terminal devices can also obtain system information (SI) from other associated cells (such as co-located cells) and synchronize with them. In addition, on-demand SSB / SIB1 can also achieve network energy saving gains by allowing longer cell dormancy and on-demand triggering of SSB / SIB1 transmission in the serving cell.

[0288] Power domain technology (Adaptation of transmission power of signals and channels / Over the air digital pre-distortion): Power domain energy-saving technology can improve system energy efficiency by adjusting signal / channel transmission power, digital pre-distortion and other methods.

[0289] Among them, adjusting the signal / channel transmission power aims to complete the adaptation of the transmission power of the downlink signal and channel by enhancing the relevant configuration of the communication terminal equipment or enhancing the feedback of the communication terminal equipment, so as to achieve network energy saving gains; the air digital pre-distortion aims to assist the gNB in ​​reducing the distortion introduced by the PA by processing the training signal through the communication terminal equipment and reporting the information required for the gNB digital pre-distortion.

[0290] Frequency domain technology (multi-carrier downlink energy-saving enhancement technology (SSB-less SCell)):

[0291] In the existing 5G network, downlink transmission energy consumption is the main aspect of network energy consumption. At present, the bandwidth of the downlink BWP is semi-statically configured, and the BWP framework allows communication terminal equipment to configure the default BWP and switch to the default BWP based on a timer. In addition, through BWP configuration and scheduling on the gNB, it is possible to reduce frequency resources within the BWP. When there is no downlink control information or data to be transmitted, the network side also shuts down some components (such as cells, frequency bands, etc.) to reduce energy consumption, and designs dynamic switching operations to maintain a balance between network energy saving and system performance. In addition, when there is no downlink control information or data transmission requirement, the transmission period of synchronization signals (such as SSB, etc.) can also be increased to reduce the energy consumption overhead caused by broadcast synchronization signals.

[0292] In the carrier aggregation scenario, since the primary cell and the secondary cell will periodically perform time synchronization (TA), the second cell can be prevented from sending SSB. When the communication terminal device needs to perform time and frequency synchronization with the second cell, it can directly obtain the synchronization information of the second cell through the first cell. This SSB-without SCell technology can effectively reduce the transmission energy consumption caused by the periodic broadcast of SSB in the second cell. The second cell that supports network energy-saving technologies such as SSB-without SCell can be called the energy-saving second cell (Energy Saving SCell).

[0293] In summary, since frequency domain energy-saving technology has high energy efficiency gain, little impact on the performance of communication terminal equipment and less changes to the network architecture, representative technologies such as SSB-less SCell are receiving more and more attention. Applying this group of technologies to 5G devices will effectively improve the system energy efficiency in existing carrier aggregation scenarios.

[0294] It should be noted that the communication terminal equipment (User Equipment, UE) is a terminal equipment used or held by users in a 5G network environment, such as a smartphone with 5G functions, or other devices with the same or similar functions. When applying the above-mentioned combined technology to improve the system energy efficiency in the network carrier aggregation scenario, at least one second cell will be added to the communication terminal equipment first. After adding the second cell, the communication terminal equipment can measure the actual network environment, and construct an activation measurement report based on the measurement results, and send the constructed measurement activation report to the first cell, so that the first cell can determine which second cells to activate. Among them, the second cell can be a secondary cell (Secondary Cell, SCell, also known as a secondary service cell) in a 5G network environment.

[0295] In actual use, the activation measurement report may include at least one of the following:

[0296] Identity information of the second cell that is successfully measured;

[0297] a measurement result of the second cell that is successfully measured;

[0298] Identity information of the second cell where the measurement fails.

[0299] It should be noted that the identity information of the second cell may be information that can be used to characterize the identity, such as the sequence number, number, unique identifier, etc. of the second cell. The measurement result may include information such as the synchronization signal block transmission frequency of the second cell, the number of synchronization signal blocks detected, and the detection duration.

[0300] Step S20: Determine the second cell to be activated according to the activation measurement report.

[0301] It should be noted that the second cell to be activated may be a second cell that requires the communication terminal device to be activated. If the state of the second cell to be activated relative to the communication terminal device becomes an activated state, it can provide corresponding services for the communication terminal device.

[0302] In actual use, after receiving the activation measurement report, the first cell can select a part of the second cell added for the communication terminal device as the second cell to be activated according to the activation measurement report. For example, a part of the second cell added for the communication terminal device with a stronger signal, a higher synchronization frequency and / or a lower load is selected as the second cell to be activated.

[0303] Step S30: Send first indication information to the second cell to be activated, and send activation indication information to the communication terminal device.

[0304] It should be noted that after determining the second cell to be activated, first indication information can be sent to the second cell to be activated to adjust its operation status. At the same time, activation indication information can be sent to the communication terminal device to instruct the communication terminal device to activate the second cell to be activated.

[0305] Among them, the first indication information is used to instruct the second cell to send a synchronization signal block in a specified manner (such as a specified frequency, period, etc.) on a specified resource (such as a specific time-frequency domain resource), or to request the second cell to send an on-demand synchronization signal block to ensure that the second cell to be activated will send a synchronization signal block in a preset configuration or a configuration specified in the first indication information, and cooperate with the relevant verification, measurement or synchronization of the communication terminal equipment.

[0306] The activation indication information is used to instruct the communication terminal device to configure the designated second cell to an activated state, and the activation indication information may include at least one of the following:

[0307] Identity information of the second community;

[0308] On-demand synchronization signal block resource configuration for the second cell;

[0309] The on-demand synchronization signal block monitoring time window of the second cell.

[0310] In actual use, the activation indication information can be transmitted through the existing carrier, for example: using the existing MAC CE or RRC signaling bearer in the current protocol. Of course, you can also choose not to reuse it, but transmit it through a new carrier, for example: through a new MAC CE or a new RRC signaling bearer.

[0311] To facilitate understanding, an example is given below:

[0312] If the first cell receives on-demand SSB (synchronization signal block, also known as on-demand synchronization signal block) measurement report information (i.e., activation measurement report) sent by the communication terminal equipment, it will select the second cell (possibly multiple cells) that need to be activated by the communication terminal equipment, that is, determine the second cell to be activated, and then send the first indication information to the second cell to be activated, and send the activation indication information to the communication terminal equipment.

[0313] The first indication information is used to indicate that the second cell that needs to be activated by the communication terminal device sends an on-demand SSB in a specified manner on specified resources; or, to request the second cell to send an on-demand SSB; the activation indication information may include, for example: the identity information of the second cell that needs to be activated, the on-demand SSB resource configuration of the second cell that needs to be activated, and (optionally) the on-demand SSB monitoring time window of the second cell that needs to be activated. The activation indication information can be carried by the SCell Activation / Deactivation MAC CE, or by the existing RRC signaling (such as SCellState), or by a newly added MAC CE, or by a newly added RRC signaling.

[0314] The method for selecting the second cell that needs to be activated by the communication terminal device can be based on the location information of the communication terminal device, the reference signal measurement result, the first cell reception information content, or the network side (the network side can be the communication base station side) indication information, etc.

[0315] In a specific implementation, the second cell to be activated may have been dormant or in a dormant state. In order to ensure that the second cell to be activated can normally send a synchronization signal block, step S30 in this embodiment may include:

[0316] Send wake-up indication information and first indication information to the second cell to be activated, and send activation indication information to the communication terminal device.

[0317] It should be noted that the wake-up indication information is used to instruct the second cell to turn on, or enter an on state.

[0318] It can be understood that the wake-up indication information and the first indication information are sent to the second cell to be activated. If the second cell to be activated is dormant or in a dormant state, it will first be turned on or enter the turned-on state according to the wake-up indication information, and then, according to the instructions of the first indication information, a synchronization signal block will be sent with a preset configuration or a configuration specified in the first indication information.

[0319] In a specific implementation, in order to ensure that the communication terminal device can perform measurements reasonably, before step S10 in this embodiment, the following may also be included:

[0320] Sending activation process configuration information to the communication terminal device;

[0321] Receiving activation requirement information sent by the communication terminal device and / or activation indication information sent by the communication base station;

[0322] Send activation measurement configuration information to the communication terminal device, and send second indication information to the second cell.

[0323] It should be noted that the activation process configuration information is used to inform the communication terminal device of configuration information related to the second cell activation process, and the activation process configuration information may include at least one of the following:

[0324] resource configuration information of the second cell;

[0325] Measurement related configuration of the second cell;

[0326] location information of the second cell or a base station to which the second cell belongs;

[0327] Area information of the service area or signal coverage area of ​​the second cell.

[0328] For example, the first cell may initialize the second cell activation process configuration, send activation process configuration information through RRC signaling, system information, MACCE, DCI and other communication methods, and inform the communication terminal device of at least one of the following configuration information related to the second cell activation process:

[0329] Configuration 1: on-demand SSB resource configuration of the second cell, including on-demand SSB time-frequency resource information, wherein the time domain resource information includes at least one of the following on-demand SSB time domain configurations:

[0330] The number of on-demand SSBs in an SSB burst;

[0331] The on-demand SSB time domain interval in an SSB burst, such as the OFDM symbol interval;

[0332] The number of SSB bursts including on-demand SSB;

[0333] The time domain interval of SSB bursts including on-demand SSB, such as OFDM symbol interval;

[0334] The monitoring time window of on-demand SSB includes the monitoring start time and monitoring duration.

[0335] Configuration 2: measurement-related configuration of the second cell, including but not limited to reference signal configuration, measurement threshold, cell offset parameter, and hysteresis parameter;

[0336] Configuration 3: location information of the second cell or the base station to which the second cell belongs;

[0337] Configuration 4: Service / coverage area information of the second cell.

[0338] It should be noted that after receiving the activation process configuration information, the communication terminal device can monitor according to the relevant configuration in the activation process configuration information, and after determining the relevant conditions for adding the cell, send the activation requirement information to the first cell.

[0339] The activation requirement information is used for at least one of the following:

[0340] Inform the first cell communication terminal device of the uplink service demand;

[0341] Notifying the communication link status information between the first cell and the communication terminal device;

[0342] Requesting the first cell to configure an activatable cell for the communication terminal device;

[0343] Requesting activation of a designated second cell;

[0344] The request is to configure the designated second cell to an activated state.

[0345] When the activation requirement information is sent, the carriers that can be used can be at least one of: a wake-up signal WUS, a scheduling request SR, a buffer status report BSR, a hybrid automatic repeat request-acknowledgement message HARQ-ACK, uplink control information UCI, and a PRACH preamble code.

[0346] In actual use, whether the communication terminal device sends the activation demand information can be judged by whether there is an uplink service demand. For example, if the communication terminal device has an uplink service demand (such as the current service cell of the communication terminal device cannot meet the current uplink service demand of the communication terminal device), a WUS can be sent to the first cell. The WUS can be a second cell activation request information. The second cell activation request information is used to inform the first cell of the uplink service demand, and / or request the first cell to configure an activatable second cell for the communication terminal device, and / or request to activate a designated second cell, and / or request to configure the designated second cell to an activated state (to handle the uplink service demand);

[0347] or,

[0348] Sending an SR to the first cell, where the SR is used to inform the first cell of the uplink service demand, and the second cell activation request information is used to inform the first cell of the uplink service demand, and / or requesting the first cell to configure an activatable second cell for the communication terminal device, and / or requesting activation of a designated second cell, and / or requesting that the designated second cell be configured as an activated state (to process the uplink service demand);

[0349] or,

[0350] Sending a BSR to the first cell, where the BSR is used to inform the first cell of the uplink service demand, and the second cell activation request information is used to inform the first cell of the uplink service demand, and / or requesting the first cell to configure an activatable second cell for the communication terminal device, and / or requesting activation of a designated second cell, and / or requesting that the designated second cell be configured as an activated state (to process the uplink service demand);

[0351] or,

[0352] Sending a HARQ-ACK to the first cell, where the HARQ-ACK is used to inform the first cell of the uplink service demand, and / or requesting the first cell to configure an activatable second cell for the communication terminal device, and / or requesting activation of a designated second cell, and / or requesting that the designated second cell be configured as an activated state (to process the uplink service demand);

[0353] or,

[0354] Sending a UCI to the first cell, where the UCI is used to inform the first cell of the uplink service demand, and / or requesting the first cell to configure an activatable second cell for the UE, and / or requesting activation of a designated second cell, and / or requesting that the designated second cell be configured as an activated state (to process the uplink service demand);

[0355] or,

[0356] Send a PRACH preamble to the first cell, where the PRACH preamble is used to inform the first cell of the uplink service demand, and / or request the first cell to configure an activatable second cell for the UE, and / or request to activate a designated second cell, and / or request to configure the designated second cell to an activated state (to handle the uplink service demand).

[0357] In actual use, whether the UE sends the activation requirement information can also be determined by whether there is a second cell or PSCell that can provide services for it.

[0358] For example: If the communication link quality between the UE and the first cell is poor; and / or, Ms + Hys1 < Thresh1, or, Ms < Thresh1, then at this time, the following can be done:

[0359] Send a WUS to the first cell. The WUS can be the second cell second activation request information, which is used to inform the first cell of the communication link status information between the first cell and the UE, and / or, request the first cell to configure an activatable second cell for the communication terminal device, and / or, request to activate a specified second cell, and / or, request to configure the specified second cell as an active state;

[0360] Or,

[0361] Send an SR to the first cell. The SR is used to inform the first cell of the communication link status information between the first cell and the communication terminal device, and / or, request the first cell to configure an activatable second cell for the communication terminal device, and / or, request to activate a specified second cell, and / or, request to configure the specified second cell as an active state;

[0362] Or,

[0363] Send a BSR to the first cell. The BSR is used to inform the first cell of the communication link status information between the first cell and the communication terminal device, and / or, request the first cell to configure an activatable second cell for the communication terminal device, and / or, request to activate a specified second cell, and / or, request to configure the specified second cell as an active state;

[0364] Or,

[0365] Send a HARQ-ACK to the first cell. The HARQ-ACK is used to inform the first cell of the communication link status information between the first cell and the communication terminal device, and / or, request the first cell to configure an activatable second cell for the communication terminal device, and / or, request to activate a specified second cell, and / or, request to configure the specified second cell as an active state;

[0366] Or,

[0367] Send a UCI to the first cell. The UCI is used to inform the first cell of the communication link status information between the first cell and the communication terminal device, and / or, request the first cell to configure an activatable second cell for the communication terminal device, and / or, request to activate a specified second cell, and / or, request to configure the specified second cell as an active state;

[0368] Or,

[0369] A PRACH preamble is sent to the first cell, where the PRACH preamble is used to inform the communication link status information between the first cell and the communication terminal device, and / or to request the first cell to configure an activatable second cell for the communication terminal device, and / or to request to activate a designated second cell, and / or to request to configure the designated second cell to an activated state.

[0370] Among them, Ms is the measurement result of the first cell (such as RSRP, RSRQ, SINR, RSCP, EcN0 of the reference signal). Optionally, Ms can also be the measurement result of the first cell without considering any bias; Hys1 is the hysteresis parameter, and its value can be configured by reportConfigNR; Thresh1 is the first threshold, and its value can be configured by reportConfigNR.

[0371] In actual use, the network (or communication base station) can also perform corresponding control. At this time, the activation indication information can be sent by the network (or communication base station). The activation indication information sent by the network (or communication base station) is used to indicate the downlink service requirements of the communication terminal device, and / or to indicate the first cell to configure the second cell for the communication terminal device.

[0372] In actual application, based on the above description, after receiving various types of activation requirement information or addition indication information, the first cell may send activation measurement configuration information to the communication terminal device and send second indication information to the second cell.

[0373] The activation measurement configuration information is used to inform the communication terminal device of the configuration information required to be used when measuring each second cell, and the activation measurement configuration information may include at least one of the following:

[0374] Identity information of the second community;

[0375] On-demand synchronization signal block resource configuration for the second cell;

[0376] A monitoring time window of an on-demand synchronization signal block of the second cell;

[0377] The PCI of the on-demand synchronization signal block of the second cell.

[0378] The second indication information is used to instruct the second cell to send a synchronization signal block in a specified manner on specified resources, or to request the second cell to send an on-demand synchronization signal block to ensure that the communication terminal equipment can correctly measure each second cell.

[0379] For example: if the first cell receives the second cell activation indication information sent by the network side (or the communication base station), if the first cell receives the WUS sent by the communication terminal device, and the WUS is the first activation request information of the second cell, if the first cell receives the WUS sent by the communication terminal device, and the WUS is the second activation request information of the second cell, if the first cell receives the SR sent by the communication terminal device, if the first cell receives the BSR sent by the communication terminal device, if the first cell receives the HARQ-ACK sent by the communication terminal device, if the first cell receives the UCI sent by the communication terminal device, or if the first cell receives the PRACH preamble sent by the communication terminal device, then the first cell may send the on-demand SSB measurement configuration information to the communication terminal device, and send the on-demand SSB second indication information to the second cell;

[0380] The second cell activation indication information sent by the network side is used to indicate the downlink service demand of the communication terminal device, and / or to instruct the first cell to configure an activatable second cell for the communication terminal device (to process the downlink service demand);

[0384] The UCI is used to inform the first cell of the uplink service demand, and / or to inform the communication link status information between the first cell and the communication terminal device, and / or to request the first cell to configure an activatable second cell for the communication terminal device, and / or to request the communication terminal device to activate a designated second cell, and / or to request the communication terminal device to configure the designated second cell to an activated state;

[0385] The PRACH preamble is used to inform the first cell of the uplink service demand, and / or to inform the communication link status information between the first cell and the communication terminal device, and / or to request the first cell to configure an activatable second cell for the communication terminal device, and / or to request the communication terminal device to activate a designated second cell, and / or to request the communication terminal device to configure the designated second cell to an activated state.

[0387] Afterwards, if the second cell receives the on-demand SSB second indication information sent by the first cell, it will send the on-demand SSB according to the on-demand SSB second indication information;

[0388] If the communication terminal device receives the on-demand SSB measurement configuration information sent by the first cell, it will detect the on-demand SSB based on the on-demand SSB measurement configuration information sent by the first cell:

[0389] If all measurement events indicated by the on-demand SSB measurement configuration information are not completed, if an on-demand SSB is detected, measurement is performed through the on-demand SSB based on the on-demand SSB measurement configuration information sent by the first cell, and then the optional processes may include:

[0390] 1. Record the measurement result Mn;

[0391] 2. Record the measurement result Mn, and at the same time, send on-demand SSB measurement report information to the first cell, where the on-demand SSB measurement report information may include, for example: a measurement result of the on-demand SSB corresponding to the second cell;

[0392] 3. Make a judgment, such as: if Mn-Hys2>Thresh2, or if Mn>Thresh2, the measurement result Mn can be recorded. Optionally, an on-demand SSB first measurement report information can also be sent to the first cell. The on-demand SSB measurement report information can include, for example: the measurement result of the on-demand SSB corresponding to the second cell.

Optionally, Mn may also be the measurement result of the second cell to which the on-demand SSB belongs without considering any bias; Hys2 is a hysteresis parameter, and the value of which can be configured by reportConfigNR; Thresh2 is a second threshold, and the value of which can be configured by reportConfigNR;

[0394] If all measurement events indicated by the on-demand SSB measurement configuration information are completed, on-demand SSB measurement report information (i.e., activation measurement report) can be sent to the first cell, and the on-demand SSB measurement report information may include, for example: identity information of the second cell corresponding to the on-demand SSB that is successfully detected / measured, and / or, measurement results of the second cell corresponding to the on-demand SSB that is successfully detected / measured, and / or, identity information of the second cell corresponding to the on-demand SSB that is unsuccessful in detection / measurement.

[0395] This embodiment receives an activation measurement report sent by a communication terminal device; determines the second cell to be activated according to the activation measurement report, and the second cell to be activated is the second cell that needs to be activated by the communication terminal device; sends first indication information to the second cell to be activated, and sends activation indication information to the communication terminal device. Due to the improvement of the cell addition and cell activation processes during the communication process, it is ensured that the power domain and time domain technologies can be used to improve the existing network communication process, so that it can further save energy and improve system energy efficiency, thereby reducing the negative impact of 5G networks on the environment.

[0399] It should be noted that the adding process configuration information is used to inform the communication terminal device of configuration information related to the second cell adding process, and the adding process configuration information includes at least one of the following:

[0403] Resource configuration of synchronization signal blocks of dormant neighboring cells of the first cell;

[0404] Resource configuration of the synchronization signal block of the non-dormant neighboring cell of the first cell.

[0405] For example, the first cell may initialize the configuration of the second cell adding process, such as sending the adding process configuration information through control information carriers such as RRC signaling, system information, MAC CE, DCI, etc., to inform the communication terminal device of at least one of the following configuration information related to the second cell adding process:

[0406] Configuration 1: measurement-related configuration of the first cell, including but not limited to reference signal configuration, measurement threshold, cell offset parameter, and hysteresis parameter;

[0407] Configuration 2: measurement-related configurations of (possibly multiple) dormant neighboring cells of the first cell, including but not limited to reference signal configuration, measurement threshold, cell offset parameter, and hysteresis parameter;

[0408] Configuration 3: measurement-related configurations of (possibly multiple) non-dormant (or enabled) neighboring cells of the first cell, including but not limited to reference signal configuration, measurement threshold, cell bias parameter, and hysteresis parameter;

[0409] Configuration 4: on-demand SSB resource configuration of (possibly multiple) dormant neighboring cells of the first cell, including on-demand SSB time-frequency resource information, wherein the time domain resource information includes at least one of the following on-demand SSB time domain configurations:

[0410] The number of on-demand SSBs in an SSB burst;

[0411] The on-demand SSB time domain interval in an SSB burst, such as the OFDM symbol interval;

[0412] The number of SSB bursts including on-demand SSB;

[0413] The time domain interval of SSB bursts including on-demand SSB, such as OFDM symbol interval;

[0414] The monitoring time window of on-demand SSB includes the monitoring start time and monitoring duration;

[0415] Configuration 5: on-demand SSB resource configuration of (possibly multiple) non-dormant neighboring cells of the first cell, including on-demand SSB time-frequency resource information, wherein the time domain resource information includes at least one of the following on-demand SSB time domain configurations:

[0417] The on-demand SSB time domain interval in an SSB burst, such as the OFDM symbol interval;

[0418] The number of SSB bursts including on-demand SSB;

[0419] The time domain interval of SSB bursts including on-demand SSB, such as OFDM symbol interval;

[0420] The monitoring time window of on-demand SSB includes the monitoring start time and monitoring duration.

[0421] Of course, one or more of the above configurations can also be configured in the communication terminal device in a pre-configured manner.

[0422] Step S02: receiving the adding requirement information sent by the communication terminal device and / or the adding indication information sent by the communication base station.

[0423] It should be noted that after receiving the adding process configuration information, the communication terminal device can monitor according to the configuration in the adding process configuration information, and send adding requirement information to the first cell when it is necessary to add the second cell.

[0424] The added requirement information is used for at least one of the following:

[0425] Inform the first cell communication terminal device of the uplink service demand;

[0426] Notifying the communication link status information between the first cell and the communication terminal device;

[0427] Requesting the first cell to configure an addable cell for the communication terminal device;

[0428] Request to add a new secondary cell.

[0429] The added demand information is sent through at least one of the carriers such as a wake-up signal WUS, a scheduling request SR, a buffer status report BSR, a hybrid automatic repeat request-acknowledgement message HARQ-ACK, uplink control information UCI, and a PRACH preamble code.

[0430] In actual use, whether the communication terminal device sends the addition demand information can be judged by whether there is an uplink service demand. For example, if there is an uplink service demand (such as the current service cell of the communication terminal device cannot meet the uplink service demand of the communication terminal device), then:

[0431] Sending a WUS to the first cell, where the WUS may be first adding request information of the second cell, where the first adding request information of the second cell is used to inform the first cell of the uplink service demand, and / or request the first cell to configure an addable second cell for the communication terminal device, and / or request to add a new second cell (to handle the uplink service demand);

[0432] or,

[0433] Sending an SR to the first cell, where the SR is used to inform the first cell of the uplink service demand, and / or requesting the first cell to configure an addable second cell for the communication terminal device, and / or requesting to add a new second cell (to handle the uplink service demand);

[0434] or,

[0435] Sending a BSR to the first cell, where the BSR is used to inform the first cell of the uplink service demand, and / or requesting the first cell to configure an addable second cell for the communication terminal device, and / or requesting to add a new second cell (to handle the uplink service demand);

[0436] or,

[0437] Sending a HARQ-ACK to the first cell, where the HARQ-ACK is used to inform the first cell of the uplink service demand, and / or requesting the first cell to configure an addable second cell for the communication terminal device, and / or requesting to add a new second cell (to handle the uplink service demand);

[0438] or,

[0439] Send UCI to the first cell, where the UCI is used to inform the first cell of the uplink service requirement, and / or, request the first cell to configure an additional second cell for the communication terminal device, and / or, request to add a new second cell (to handle the uplink service requirement);

[0440] Or,

[0441] Send a PRACH preamble to the first cell, where the PRACH preamble is used to inform the first cell of the uplink service requirement, and / or, request the first cell to configure an additional second cell for the communication terminal device, and / or, request to add a new second cell (to handle the uplink service requirement).

[0442] In actual use, whether the communication terminal device sends an addition requirement message can also be determined by whether there is a second cell or PSCell that can provide services for it. For example: If the communication link quality between the communication terminal device and the first cell is poor; and / or, Ms + Hys1 < Thresh1, or, Ms < Thresh1, then at this time, it is possible to:

[0443] Send WUS to the first cell, where the WUS can be a second cell second addition request message, and the second cell second addition request message is used to inform the first cell of the communication link status information between the first cell and the communication terminal device, and / or, request the first cell to configure an additional SCell for the communication terminal device, and / or, request to add a new SCell;

[0444] Or,

[0445] Send SR to the first cell, where the SR is used to inform the first cell of the communication link status information between the first cell and the communication terminal device, and / or, request the first cell to configure an additional SCell for the communication terminal device, and / or, request to add a new SCell;

[0446] Or,

[0447] Send BSR to the first cell, where the BSR is used to inform the first cell of the communication link status information between the first cell and the communication terminal device, and / or, request the first cell to configure an additional SCell for the communication terminal device, and / or, request to add a new SCell;

[0448] Or,

[0449] Send HARQ-ACK to the first cell, where the HARQ-ACK is used to inform the first cell of the communication link status information between the first cell and the communication terminal device, and / or, request the first cell to configure an additional SCell for the communication terminal device, and / or, request to add a new SCell;

[0450] or,

[0451] Sending UCI to the first cell, where the UCI is used to inform the communication link state information between the first cell and the communication terminal device, and / or requesting the first cell to configure an addable SCell for the communication terminal device, and / or requesting to add a new SCell;

[0452] or,

[0453] A PRACH preamble is sent to the first cell, where the PRACH preamble is used to inform the communication link status information between the first cell and the communication terminal device, and / or to request the first cell to configure an addable SCell for the communication terminal device, and / or to request to add a new SCell.

[0454] In actual use, the communication base station can also perform corresponding control. At this time, the adding indication information can be sent by the communication base station. The adding indication information sent by the communication base station is used to indicate the downlink service requirements of the communication terminal device, and / or indicate the first cell configuration to add the second cell.

[0455] Step S03: Sending added measurement configuration information to the communication terminal device.

[0456] Step S04: Send third indication information to the second cell to be added.

[0457] It should be noted that the second cell to be added may be a second cell that can be configured for the communication terminal device.

[0458] In actual application, after receiving various types of adding requirement information or adding indication information, the first cell may send activation measurement configuration information to the communication terminal device and send second indication information to the second cell.

[0459] The added measurement configuration information is used to inform the communication terminal device of the configuration information required to be used when measuring each second cell during the process of adding the second cell. The added measurement configuration information may include at least one of the following:

[0460] Identity information of the second cell to be added;

[0461] On-demand synchronization signal block resource configuration of the second cell to be added;

[0462] A monitoring time window of an on-demand synchronization signal block of a second cell to be added;

[0463] The PCI of the on-demand synchronization signal block of the second cell to be added.

[0464] The third indication information is used to instruct the second cell to be added to send a synchronization signal block in a specified manner on specified resources; or, to request the second cell to be added to send an on-demand synchronization signal block.

[0465] For example: if the first cell receives a WUS sent by a communication terminal device, and the WUS is the first addition request information of the second cell, if the first cell receives a WUS sent by a communication terminal device, and the WUS is the second addition request information of the second cell, if the first cell receives an SR sent by the communication terminal device, if the first cell receives a BSR sent by the communication terminal device, if the first cell receives an UCI sent by the communication terminal device, if the first cell receives a PRACH preamble sent by the communication terminal device, if the first cell receives second cell addition indication information sent by the communication base station, then on-demand SSB measurement configuration information (i.e., adding measurement configuration information) can be sent to the communication terminal device, and on-demand SSB third indication information can be sent to the neighboring cell (second cell) of the first cell. If necessary, the first cell can also choose to send a second cell addition request information to the communication base station, and the second cell addition request information can be used to request the addition of a new second cell.

[0466] Among them, in the above content, the SR is used to inform the first cell of the uplink service demand, and / or, to inform the communication link status information between the first cell and the communication terminal device, and / or, to request the first cell to configure an addable second cell for the communication terminal device, and / or, to request to add a new second cell;

[0467] The BSR is used to inform the first cell of the uplink service demand, and / or to inform the communication link status information between the first cell and the communication terminal device, and / or to request the first cell to configure an addable second cell for the communication terminal device, and / or to request to add a new second cell;

[0468] The UCI is used to inform the first cell of the uplink service demand, and / or to inform the communication link status information between the first cell and the communication terminal device, and / or to request the first cell to configure an addable second cell for the communication terminal device, and / or to request to add a new second cell;

[0469] The PRACH preamble is used to inform the first cell of the uplink service demand, and / or to inform the communication link status information between the first cell and the communication terminal device, and / or to request the first cell to configure an addable second cell for the communication terminal device, and / or to request to add a new second cell;

[0470] The on-demand SSB measurement configuration information may include: (possible) identity information of the second cell, on-demand SSB resource configuration of the second cell, monitoring time window of the on-demand SSB of the second cell, and PCI of the on-demand SSB of the second cell; the on-demand SSB third indication information may be used to instruct the neighboring cell to send an on-demand SSB in a specified manner on specified resources; or, to request the neighboring cell to send an on-demand SSB.

[0471] Afterwards, if the communication base station receives the second cell adding request information sent by the first cell, or if the communication terminal device has a downlink service demand and the current serving cell cannot meet its demand, the communication base station can:

[0472] Sending first adding indication information of a second cell to the first cell, where the first adding indication information of the second cell may include, for example: a list of cells that the first cell can add to the communication terminal device, and / or on-demand SSB configuration information of the cells in the cell list, and / or measurement configuration information of the cells in the cell list;

[0473] or,

[0474] Sending on-demand SSB second indication information to a neighboring cell of the first cell, where the on-demand SSB second indication information may be used to instruct the neighboring cell to send an on-demand SSB in a specified manner on specified resources; or, to request the neighboring cell to send an on-demand SSB;

[0475] or,

[0476] Sending on-demand SSB second indication information to a cell (a neighboring cell other than the first cell) (which may provide services for the communication terminal device), wherein the on-demand SSB second indication information may be used to instruct the neighboring cell to send an on-demand SSB in a specified manner on specified resources; or, to request the neighboring cell to send an on-demand SSB.

[0477] Afterwards, if the communication terminal device receives the add measurement configuration information sent by the first cell, the on-demand SSB can be detected based on the add measurement configuration information:

[0478] If all measurement events indicated by the added measurement configuration information are not completed, if an on-demand SSB is detected at this time, measurement can be performed through the on-demand SSB based on the added measurement configuration information sent by the first cell, and then the optional processes may include:

[0479] 1. Record the measurement result Mn;

[0480] 2. Record the measurement result Mn, and at the same time, send on-demand SSB measurement report information to the first cell, where the on-demand SSB measurement report information may include, for example: the measurement result of the cell corresponding to the on-demand SSB;

[0481] 3. Make a judgment, such as: if Mn-Hys2>Thresh2, or, Mn>Thresh2, then the measurement result Mn can be recorded. Optionally, on-demand SSB measurement report information can also be sent to the first cell. The on-demand SSB measurement report information can include, for example: the measurement result of the cell corresponding to the on-demand SSB.

[0482] If all measurement events indicated by the added measurement configuration information are completed, on-demand SSB measurement report information (i.e., adding a measurement report) can be sent to the first cell, and the on-demand SSB measurement report information may include, for example: identity information of the on-demand SSB corresponding cell that is successfully detected / measured, and / or, measurement results of the on-demand SSB corresponding cell that is successfully detected / measured, and / or, identity information of the on-demand SSB corresponding cell that fails to detect / measure.

[0483] In a specific implementation, in order to reasonably add the second cell, after step S04 in this embodiment, the following may also be included:

[0484] Receiving an add measurement report sent by the communication terminal device;

[0485] Determining that a second cell needs to be added according to the adding measurement report;

[0486] Sending adding notification information to the second cell to be added;

[0487] Sending first cell adding indication information to the communication terminal device.

[0488] It should be noted that the added measurement report may be report information constructed according to the measurement result after the communication terminal device performs measurement according to the added measurement configuration information, and the added measurement report includes at least one of the following:

[0489] Identity information of the second cell to be added that is successfully measured;

[0490] The measurement result of the second cell to be added that is successfully measured;

[0491] Identity information of the second cell to be added where the measurement fails.

[0492] The second cell to be added is the second cell to be added and configured to the second cell list by the communication terminal device. The adding notification information is used to notify the communication terminal device to add the second cell to be added to the second cell list. The first cell adding indication information is used to instruct the communication terminal device to add the second cell to be added to the second cell list.

[0493] For example: if the first cell receives an add measurement report sent by a communication terminal device, it will select the second cell that needs to be added by the communication terminal device (i.e., the second cell needs to be added) based on the measurement report information, and then send an add notification information to the second cell to be added; and send the second cell first cell add indication information to the communication terminal device.

[0494] Afterwards, if the communication terminal device receives the first cell adding indication information sent by the first cell, it will add the specified second cell to be added to the second cell list based on the first cell adding indication information, and then set the second cell added to the list to a deactivated state, or deactivate the added second cell;

[0495] Optionally, if the first cell adding indication information includes activation indication information, such as through the SCellstate indication in SCellToAddModList, the second cell may be activated / deactivated based on the activation indication information in the first cell adding indication information;

[0496] Similarly, if the first cell adding indication information does not include activation indication information, the second cell added to the list may be set to a deactivated state.

[0497] It should be noted that, after activation, the first cell may also control to deactivate part of the second cells. In this case, after step S30 in this embodiment, the following may also be included:

[0498] Determining a second cell to be deactivated;

[0499] Sending deactivation notification information to the second cell to be deactivated;

[0500] Send cell deactivation indication information to the communication terminal equipment.

[0501] It should be noted that the second cell to be deactivated is a second cell that has been set to an activated state by the communication terminal. The deactivation notification information is used to inform the communication terminal device that the second cell to be deactivated is about to be or has been deactivated, or is about to be or has been configured to be deactivated by the communication terminal; the deactivation indication information is used to instruct the communication terminal device to deactivate the second cell to be deactivated, or to configure the second cell to be deactivated to be in a deactivated state.

[0502] In actual use, if the communication terminal device receives the cell deactivation indication information, it will deactivate one or more second cells in the second cell list based on the cell deactivation indication information, or configure them to a deactivated state.

[0503] In a specific implementation, the second cell to be deactivated may be determined according to an indication from the network (or base station) side. In this case, the step of determining the second cell to be deactivated in this embodiment may include:

[0504] Receiving network (or base station) side cell deactivation information sent by the network (or base station);

[0505] A second cell to be deactivated is determined according to the cell deactivation information.

[0506] It should be noted that the cell deactivation information on the network (or base station) side is used to instruct the first cell to order the communication terminal device to deactivate the designated second cell, or to instruct the first cell to order the communication terminal device to configure the designated second cell to a deactivated state.

[0507] For example: if the first cell receives the second cell deactivation information sent by the network (or base station) side (i.e., the cell deactivation information on the network (or base station) side), it can determine the second cell that needs to be deactivated (i.e., the second cell to be deactivated) based on the second cell deactivation information. After that, the first cell can send deactivation notification information to the second cell that needs to be deactivated; and send second cell deactivation indication information to the communication terminal device.

[0508] In a specific implementation, the second cell to be deactivated may also be determined according to the load or demand quantity of the second cell. In this case, the step of determining the second cell to be deactivated in this embodiment may include:

[0509] counting the number of service demands of the communication terminal and / or the workload of the second cell;

[0510] The second cell to be deactivated is determined according to the number of service demands of the communication terminal and / or the workload of the second cell.

[0511] For example: if a second cell is configured to be activated by a communication terminal device, or the second cell is activated by the communication terminal device, but the second cell has no service demand from the communication terminal device within a period of time tn (tn>0) and / or the second cell has a low workload (such as a load ratio lower than a preset threshold), then the second cell can be used as a second cell to be deactivated.

[0512] In a specific implementation, the second cell to be deactivated may also be determined according to the demand or operation status of the second cell. In this case, the step of determining the second cell to be deactivated in this embodiment may include:

[0513] Counting the energy saving demand of the second cell, and / or the synchronization signal block sending frequency of the second cell, and / or the operation status of the second cell;

[0514] The second cell to be deactivated is determined based on the energy saving requirement of the second cell, and / or the synchronization signal block sending frequency of the second cell, and / or the operating status of the second cell.

[0515] For example: If a second cell is configured to be activated by a communication terminal device, or the second cell is activated by the communication terminal device, but it is detected that the second cell has energy saving requirements, and / or the synchronization signal block sending frequency is low (such as lower than a preset frequency threshold), and / or the second cell is dormant or in a dormant state, then the second cell can be used as a second cell to be deactivated.

[0516] Of course, when the first cell detects that the communication terminal device has specific requirements (such as emergency services), it can also use some of the second cells in the second cell list corresponding to the communication terminal device as second cells to be deactivated.

[0517] In a specific implementation, the second cell to be deactivated may also be determined by the communication terminal device. In this case, the step of determining the second cell to be deactivated in this embodiment may include:

[0518] Receiving cell deactivation request information sent by a communication terminal device;

[0519] A second cell to be deactivated is determined according to the cell deactivation request information.

[0520] It should be noted that the cell deactivation request information is used to request deactivation of a specified second cell, or to request to configure a specified second cell to a deactivated state. The communication terminal device can send the cell deactivation request information when there is a specific need to request to deactivate a second cell.

[0521] For example, if a second cell is configured as an activated state by a communication terminal device, or the second cell is activated by the communication terminal device, at this time, if the communication terminal device suddenly has an urgent service demand, or the synchronization signal block transmission frequency of the second cell is low and does not meet the current service demand of the communication terminal device, then at this time, the communication terminal device can send a cell deactivation request message to the first cell, requesting that the specific second cell be set as the second cell to be deactivated, thereby deactivating the second cell;

[0522] Alternatively, if the communication terminal device detects that the communication link status with the second cell is poor, or the synchronization signal block sending frequency of the second cell is low and does not meet the current service needs of the communication terminal device, then the communication terminal device can send a cell deactivation request message to the first cell, requesting that the specific second cell be set as the second cell to be deactivated, thereby deactivating the second cell.

[0523] It should be noted that, after activation, the first cell may also control the release of part of the second cell. In this case, after step S30 in this embodiment, the following may also be included:

[0524] Determine a second cell to be released;

[0525] Sending release notification information to the second cell to be released;

[0526] Send second cell release indication information to the communication terminal device.

[0527] It should be noted that the second cell to be released is a second cell that has been added and configured by the communication terminal. The release notification information is used to notify the communication terminal device that the second cell to be released is about to be released or has been released, or is about to be released or has been configured as a released state by the communication terminal device; the release indication information is used to instruct the communication terminal device to release the second cell to be released, or to configure the second cell to be released as a released state.

[0528] In actual use, if the communication terminal device receives the second cell release indication information, it will release one or more second cells in the second cell list based on the second cell release indication information, or configure them to a released state.

[0529] In a specific implementation, the second cell to be released may be determined according to an indication from the network (or base station) side. In this case, the step of determining the second cell to be released in this embodiment may include:

[0530] Receiving network (or base station) side second cell release information sent by the network (or base station) side;

[0531] The second cell to be released is determined according to the second cell release information.

[0532] It should be noted that the second cell release information on the network (or base station) side is used to instruct the first cell to order the communication terminal device to release the designated second cell, or to instruct the first cell to order the communication terminal device to configure the designated second cell to a released state.

[0533] For example: if the first cell receives the second cell release information sent by the network (or base station) side (i.e., the second cell release information on the network (or base station) side), it can determine the second cell that needs to be released (i.e., the second cell to be released) based on the second cell release information on the network (or base station) side. After that, the first cell can send release notification information to the second cell that needs to be released, and send second cell release indication information to the communication terminal device.

[0534] In a specific implementation, the second cell to be released may also be determined according to the load or demand quantity of the second cell. In this case, the step of determining the second cell to be released in this embodiment may include:

[0535] counting the number of service demands of the communication terminal and / or the workload of the second cell;

[0536] The second cell to be released is determined according to the number of service demands of the communication terminal and / or the workload of the second cell.

[0537] For example: if a second cell is configured as a deactivated state by a communication terminal device, or the second cell is deactivated by the communication terminal device, but the second cell has no service demand from the communication terminal device within a period of time tr (tr>0) and / or the second cell has a low workload (such as a load ratio lower than a preset threshold), then the second cell can be used as a second cell to be released.

[0538] In a specific implementation, the second cell to be released may also be determined according to the demand, transmission frequency or operation status of the second cell. In this case, the step of determining the second cell to be released in this embodiment may include:

[0539] Counting the energy saving demand of the second cell, and / or the synchronization signal block sending frequency of the second cell, and / or the operation status of the second cell;

[0540] The second cell to be released is determined based on the energy saving requirement of the second cell, and / or the synchronization signal block sending frequency of the second cell, and / or the operating status of the second cell.

[0541] For example: if a second cell is configured to be in a deactivated state by a communication terminal device, or the second cell is deactivated by the communication terminal device, if the SSB transmission frequency of the second cell is low, and / or if the second cell is dormant or in a dormant state, and / or if the second cell has energy saving requirements, the second cell can be used as a second cell to be released.

[0542] In a specific implementation, the second cell to be released may also be determined by the communication terminal device. In this case, the step of determining the second cell to be released in this embodiment may include:

[0543] Receiving second cell release request information sent by a communication terminal device;

[0544] The second cell to be released is determined according to the second cell release request information.

[0545] It should be noted that the second cell release request information is used to request the release of a specified second cell, or to request the specified second cell to be configured as a released state. The communication terminal device can send the second cell release request information when there is a specific need to request the release of a second cell.

[0546] For example: if a second cell in the second cell list of the communication terminal device is configured as a deactivated state, or the second cell is deactivated, if it is detected that the communication link state between the communication terminal device and the second cell is poor, and / or the transmission frequency of the synchronization signal block of the second cell is low, then a second cell release request message can be sent to the first cell to request the release of the second cell through the second cell release request message.

[0547] This embodiment also makes corresponding improvements to the corresponding process of adding a cell, ensuring that various energy-saving technologies can be applied when adding a cell, thereby further improving the energy efficiency of the system.

[0548] The embodiment of the present invention also provides a communication method, referring to Figure 4 , Figure 4 FIG. 4 is a flow chart of a third embodiment of a communication method according to the present invention.

[0549] In this embodiment, the communication method is applied to the second cell;

[0550] The communication method comprises the following steps:

[0551] Step S100: Receive first indication information sent by a first cell.

[0552] It should be noted that the first indication information is used to instruct the second cell to send a synchronization signal block in a specified manner (such as a specified frequency, period, etc.) on specified resources (such as specific time-frequency domain resources), or to request the second cell to send an on-demand synchronization signal block to ensure that the second cell to be activated will send a synchronization signal block in a preset configuration or a configuration specified in the first indication information, and cooperate with the relevant verification, measurement or synchronization of the communication terminal equipment.

[0553] Step S200: Send a synchronization signal block according to the first indication information.

[0554] It can be understood that if the first indication information sent by the first cell is received, it means that relevant verification, measurement or synchronization is required at this time. At this time, the synchronization signal block can be sent according to the preset frequency according to the first indication information, or the synchronization signal block can be sent according to the configuration information in the first indication information.

[0555] In a specific implementation, the second cell may be dormant or in a dormant state. In this case, the first cell may synchronously send the wake-up indication information and the first indication information. At this time, step S100 in this embodiment may include:

[0556] Receiving first indication information and wake-up indication information sent by the first cell;

[0557] The step S200 may include:

[0558] A synchronization signal block is sent according to the first indication information, and the operation of the second cell is controlled according to the wake-up indication information.

[0559] It should be noted that the wake-up indication information is used to indicate that the second cell is turned on, or enters an on state.
