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 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. 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.

[0199] 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.

[0200] In this embodiment, the communication method is applied to the first cell;

[0201] The communication method comprises the following steps:

[0202] Step S10: Send first measurement configuration information to the communication terminal equipment, and send first indication information to the second cell to be activated.

[0203] 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.

[0204] 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 cycles on the network side / base station side. Common time domain energy saving technologies include discontinuous transmission (DTX) / discontinuous reception (DRX); adjusting the general signal / channel cycle; adjusting the special signal / channel cycle of communication terminal equipment; designing on-demand SSB / SIB1; designing dynamic cell sleep / wake-up processes, etc.

[0205] Among them, the current standard supports SSB / SIB1-less operation in intra-band carrier aggregation (CA) scenarios, and the communication terminal equipment that needs to be served by the secondary cell (SCell) can be synchronized through the first cell. For non-carrier aggregation scenarios, the communication terminal equipment 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 sleep and on-demand triggering of SSB / SIB1 transmission of the serving cell.

[0206] 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.

[0207] 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.

[0208] Frequency domain technology (multi-carrier downlink energy-saving enhancement technology (SSB-less SCell)):

[0209] 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.

[0210] 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 Energy Saving SCell.

[0211] 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.

[0212] It should be noted that the second cell to be activated is a second cell that has been added for the communication terminal device, wherein the communication terminal device (User Equipment, UE) is a terminal device used or held by a user in a 5G network environment, such as a smartphone with 5G function, or other devices with the same or similar functions; the second cell can be a secondary cell (Secondary Cell, SCell, also known as a secondary service cell) in a 5G network environment, or a base station to which the secondary cell belongs. 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 device first, and after determining the second cell to be activated, the communication terminal device can measure the actual network environment to determine which second cells to activate and provide services for them, and in order to facilitate the measurement, the main cell can send first measurement configuration information to the general terminal device and send first indication information to each second cell to be activated.

[0213] In actual use, the first measurement configuration information is used to inform the communication terminal device of configuration information related to the second cell activation selection process. On this basis, the first measurement configuration information may include at least one of the following:

[0214] Identity information of the second cell to be activated;

[0215] On-demand synchronization signal block resource configuration of the second cell to be activated;

[0216] a monitoring time window of an on-demand synchronization signal block of a second cell to be activated;

[0217] The PCI of the on-demand synchronization signal block of the second cell to be activated.

[0218] The identity information of the second cell to be activated may be the serial number of the second cell to be activated, such as a physical cell ID (PCI) of the second cell.

[0219] The first indication information is used to instruct the second cell to be activated to send an on-demand synchronization signal block (on-demand SSB) to cooperate with the user communication equipment to perform communication measurement. On this basis, the first indication information may include at least one of the following:

[0220] Instructing the second cell to be activated to send indication information of an on-demand synchronization signal block on specified resources in a specified manner;

[0221] Instruct the second cell to be activated to send indication information of the on-demand synchronization signal block.

[0222] For example: the first cell may send first measurement configuration information to the communication terminal device, and at the same time, send first indication information to the second cell to be activated (the second cell that needs to be activated for the communication terminal device).

[0223] Among them, the first indication information is used to instruct the second cell that needs to be activated for the communication terminal equipment to send an on-demand SSB (on-demand synchronization signal block) in a specified manner on specified resources; or, to request the second cell to send an on-demand SSB; the first measurement configuration information content may include information such as: 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, PCI of the on-demand SSB of the second cell, and other information.

[0224] Step S20: receiving the first measurement report information sent by the communication terminal device, and selecting a target cell to be activated from the second cells to be activated according to the first measurement report information.

[0225] It should be noted that the target cell to be activated is a second cell selected from the second cells to be activated and needs to be activated by the communication terminal device. The first measurement report information may include a measurement result of the second cell to be activated.

[0226] In the specific implementation, if the second cell to be activated receives the first indication information sent by the first cell, it will send the synchronization signal block in a preset manner according to the instructions of the first indication information, or send the on-demand synchronization signal block in a specified manner on the specified resources according to the instructions of the first indication information.

[0227] When the communication terminal device receives the first measurement configuration information sent by the first cell, it will monitor the synchronization signal blocks sent by each second cell according to the monitoring configuration in the first measurement configuration information, and when the monitoring is completed, it will send the first measurement report information to the first cell. After that, the first cell will select at least one from the second cells to be activated as the target cell to be activated based on the first measurement report information.

[0228] For example: if the communication terminal device receives the first measurement configuration information sent by the first cell, it will detect the on-demand SSB sent by the second cell based on the first measurement configuration information, such as: monitoring the monitoring time window of the second cell to detect the on-demand SSB of the second cell of the corresponding identity;

[0229] During the monitoring process, if the detection of the (possibly multiple) monitoring time windows indicated by the on-demand SSB measurement configuration information is not completed, the monitoring may be continued:

[0230] At this time, if an on-demand SSB of a second cell is detected within the monitoring time window of the second cell, measurement can be performed using the detected on-demand SSB, and during this process, the measurement result Mn can be directly recorded;

[0231] or,

[0232] While recording the measurement result Mn, sending on-demand SSB first measurement report information to the first cell, the on-demand SSB first measurement report information may include, for example: the measurement result of the second cell;

[0233] Of course, the subsequent operations can also be performed only when certain conditions are met, such as Mn-Hys2>Thresh2, or Ms>Thresh2, then:

[0234] Only the measurement result Mn is recorded;

[0235] or, alternatively,

[0236] The measurement result Mn is recorded, and on-demand SSB first measurement report information is sent to the first cell. The on-demand SSB first measurement report information may include, for example, the measurement result of the second cell.

[0237] or, alternatively,

[0238] A second WUS is sent to the second cell, wherein the second WUS is used to inform / instruct the second cell to enter an activation state for the communication terminal equipment, or the second cell is activated by a designated communication terminal equipment, and / or to inform / instruct the second cell to turn on or switch to an on state, and / or to inform / instruct the second cell to send an on-demand SSB on designated resources.

[0239] Or, optionally, directly end the on-demand SSB monitoring measurement process;

[0240] Among them, Mn may be the measurement result of the second cell, or Mn may be the measurement result of the second cell without considering any bias; Hys2 is a hysteresis parameter, for example: this value may be configured by reportConfigNR; Thresh2 is a second threshold, for example: this value may be configured by reportConfigNR;

[0241] In actual use, if the first cell receives the first measurement report information sent by the communication terminal device, it can select some cells suitable for providing services to the communication terminal device from the second cell to be activated as the target cell to be activated based on the measurement result in the first measurement report information.

[0242] Step S30: Send first activation indication information to the communication terminal device, and send activation request information to the target cell to be activated.

[0243] It should be noted that after determining the target cell to be activated, it is necessary to ensure that the target cell to be activated is activated relative to the communication terminal device. At this time, first activation indication information can be sent to the communication terminal device, and activation request information can be sent to the target cell to be activated.

[0244] In actual use, the first activation indication information is used to inform the communication terminal device of the relevant information of the second cell that needs to be activated; the activation request information is used to inform the communication terminal device that the second cell is about to be activated by a certain communication terminal device, requesting it to perform corresponding actions (such as sending a synchronization signal block) to facilitate the communication terminal device to perform the activation process.

[0245] The first activation indication information may include at least one of the following:

[0246] Identity information of the second cell to be activated (i.e., the target cell to be activated);

[0247] On-demand synchronization signal block resource configuration of the second cell to be activated (i.e., the target cell to be activated);

[0248] The on-demand synchronization signal block monitoring time window of the second cell that needs to be activated (i.e. the target cell to be activated).

[0249] The activation request information may include at least one of the following:

[0250] The second cell needs to send indication information of an on-demand synchronization signal block on designated resources;

[0251] Indication information indicating that the second cell needs to be turned on or needs to be switched to an on state.

[0252] For example: after determining the target cell to be activated, the first cell may send first activation indication information to the communication terminal device, and at the same time, send activation request information to the target cell to be activated (the second cell that needs to be activated for the communication terminal device), and the first activation indication information may include information such as: identity information of the second cell to be activated, on-demand SSB resource configuration of the second cell to be activated, and on-demand SSB monitoring time window of the second cell to be activated; the activation request information may include information such as: indication information that the second cell needs to send on-demand SSB on designated resources, and information that the second cell needs to be turned on or needs to be switched to an on state;

[0253] If the target cell to be activated receives the activation request information sent by the first cell, and if the target cell to be activated is already turned on or in an turned-on state, the on-demand SSB can be sent according to the activation request information configuration;

[0254] If the target cell to be activated is dormant or in a dormant state, it can be turned on or switched to an on state, and then the synchronization signal block is sent according to the basic frequency, or the synchronization signal block is sent according to the configuration in the activation request information;

[0255] If the communication terminal device receives the first activation indication information sent by the first cell, it may monitor the on-demand SSB sent by the second cell based on the first activation indication information sent by the first cell, for example: monitoring the monitoring time window of the second cell to detect the on-demand SSB of the second cell;

[0256] If an on-demand SSB of the second cell is detected within the monitoring time window, synchronization may be performed via the on-demand SSB;

[0257] In a specific implementation, the first cell may also be configured by sending information initialization. In this case, before step S10 in this embodiment, the following may also be included:

[0258] Sending first activation selection process configuration information to the communication terminal device, and / or sending second activation selection process configuration information to the second cell.

[0259] It should be noted that the first activation selection process configuration information is used to inform the communication terminal device of the configuration information related to the second cell activation selection process; the second activation selection process configuration information is used to inform the second cell of the configuration information related to the second cell activation selection process.

[0260] In actual use, the first activation selection process configuration information includes at least one of the following:

[0261] resource configuration of a synchronization signal block of the second cell;

[0262] Measurement related configuration of the second cell;

[0263] Wake-up signal configuration of the second cell;

[0264] location information of the second cell or a base station to which the second cell belongs;

[0265] Area information of the service area or signal coverage area of ​​the second cell.

[0266] The second activation selection process configuration information includes at least one of the following:

[0267] resource configuration of an on-demand synchronization signal block of the second cell;

[0268] Service / coverage area information of the second cell.

[0269] For example, the first cell may initialize the second cell activation selection process configuration by sending the first activation selection process configuration information, for example, by informing the communication terminal device of at least one of the following five types of configuration information related to the second cell activation selection process through RRC signaling, system information, MAC CE, and DCI:

[0270] 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:

[0271] The number of on-demand SSBs in an SSB burst;

[0272] The on-demand SSB time domain interval in an SSB burst, such as the OFDM symbol interval;

[0273] The number of SSB bursts including on-demand SSB;

[0274] The time domain interval of SSB bursts including on-demand SSB, such as OFDM symbol interval;

[0275] The monitoring time window of on-demand SSB includes the monitoring start time and monitoring duration.

[0276] Configuration 2: measurement-related configuration of the second cell, including at least reference signal configuration, measurement threshold, cell offset parameter, and hysteresis parameter;

[0277] Configuration 3: The second WUS configuration of the second cell, including second WUS signal construction / selection information and second WUS time-frequency resource information; wherein the second WUS signal construction / selection information includes at least one of the following: selecting PRACH as the indication information of the second WUS, such as selecting PRACH preamble as the wake-up information carrier; signal construction information of the second WUS.

[0278] Among them, the second WUS time-frequency resource information may include at least one of the number of times the second WUS is sent, the sending time interval of the second WUS, the sending time period of the second WUS, the frequency domain resources of the second WUS, the beam combination of the second WUS, etc.

[0279] Configuration 4: location information of the second cell or the base station to which the second cell belongs;

[0280] Configuration 5: Service / coverage area information of the second cell.

[0281] When necessary, the first cell may also send second activation selection process configuration information to initialize the second cell activation selection process configuration through the configuration information, including configuring at least one of the following information related to the second cell activation selection process for the second cell:

[0282] on-demand SSB resource configuration of the second cell, including on-demand SSB time and frequency resource information;

[0283] Service / coverage area information of the second cell.

[0284] It should be noted that after activation, the first cell may also monitor the status of each second cell and perform corresponding control to control the deactivation of some second cells, for example:

[0285] If it is detected that a second cell is in an activated state for a communication terminal device, or the second cell is activated by the communication terminal device, but there is no service demand of the communication terminal device within a period of time tn (tn>0), the first cell may send deactivation notification information to the second cell, and at the same time, may also send second cell deactivation indication information to the communication terminal device; wherein the deactivation notification information is used to inform the second cell that the communication terminal device enters a deactivated state; or the second cell is deactivated by the communication terminal device; the second cell deactivation indication information is used to instruct the communication terminal device to deactivate the second cell;

[0286] Or if the SSB transmission frequency of the second cell is low, but the communication terminal device has an urgent task or a service with high service demand, deactivation notification information may be sent to the second cell, and at the same time, second cell deactivation indication information may be sent to the communication terminal device;

[0287] Alternatively, if the second cell has energy saving requirements, at this time, if the workload of the second cell is low, or there are (possibly multiple) second cells that can provide services for the communication terminal device, deactivation notification information may also be sent to the second cell, and at the same time, second cell deactivation indication information may also be sent to the communication terminal device;

[0288] Furthermore, if it is detected that the link state between the second cell and the communication terminal device is poor and the workload of the second cell is low, deactivation notification information may be sent to the second cell, and at the same time, second cell deactivation indication information may be sent to the communication terminal device;

[0289] If the communication terminal device receives the second cell deactivation indication information sent by the first cell, it will deactivate the designated second cell based on the second cell deactivation indication information;

[0290] If the second cell receives the deactivation notification information, further analysis can be performed:

[0291] If it is determined that the number of communication terminal devices that need to be served by the second cell is less than n off1 (n off1 >0), it can be determined that there are almost no communication terminal devices that need it to continue to provide services and / or sleep or enter a dormant state;

[0292] If it is determined that the number of communication terminal devices provided by the second cell is greater than n off1 , and is less than n off2 (0 <n off1 <n off2 )(Note: the second cell may serve as the second cell of multiple first cells s at the same time), however, if the second cell does not receive a keep-alive information indication from (possibly multiple) first cells within a period of time tn (tn>0), it can be determined that almost no communication terminal equipment needs it to continue to provide services, and / or sleep or enter a dormant state;

[0293] If the second cell receives a keep-activated information indication from (possibly multiple) first cells within a period of time tn (tn>0), it is determined that there are still communication terminal devices that need to continue to provide services, and / or remain turned on or remain in an on state;

[0294] If the second cell does not receive any indication of keep-activated information from (possibly multiple) first cells within a period of time tkn (tkn>tn), it is determined that there are almost no communication terminal devices that need it to continue to provide services and / or sleep or enter a sleep state.

[0295] It should be noted that after activation, the status of each second cell can also be monitored and corresponding control can be performed to control the deletion of some second cells, for example:

[0296] If a second cell is in an activated state for a communication terminal device, or the second cell is activated by the communication terminal device:

[0297] If the SSB transmission frequency of the second cell is reduced, deletion notification information may be sent to the second cell, and at the same time, second cell deletion indication information may be sent to the communication terminal device;

[0298] Among them, the second cell deletion indication information is used to instruct the communication terminal device to release the second cell, or to instruct the communication terminal device to remove the second cell from the second cell list; the deletion notification information is used to inform the communication terminal device that the second cell is released, or to inform the communication terminal device that the second cell is removed from the second cell list.

[0299] Afterwards, if the communication terminal device detects that the SSB transmission frequency of a certain activated second cell is reduced, it may send a second cell deletion request message to the first cell, and at the same time, may send a deletion notification message to the second cell;

[0300] Among them, the second cell deletion indication information is used to request the communication terminal device to release the second cell, or to request the communication terminal device to remove the second cell from the second cell list; the deletion notification information is used to inform the communication terminal device that the second cell is released, or to inform the communication terminal device that the second cell is removed from the second cell list.

[0301] It should be noted that after activation, the communication terminal device may also perform data synchronization (such as when the communication terminal device determines that it may lose synchronization with the second cell, or determines that it loses synchronization with the second cell, it sends synchronization request information to the network, and the synchronization request information is used to request the network to send an on-demand SSB), or measure the second cell. For example, if the first cell receives the synchronization request information sent by the communication terminal device, it may send on-demand SSB synchronization indication information to the communication terminal device, and at the same time, it may also send on-demand SSB third indication information to the second cell;

[0302] Among them, the synchronization indication information may include, for example: indication information that the communication terminal equipment needs to be synchronized through on-demand SSB, and / or, the on-demand SSB resource configuration of the second cell, and / or, the monitoring time window of the on-demand SSB of the second cell; the third indication information is used to instruct the second cell to send an on-demand SSB on designated resources, or to instruct the second cell to send an on-demand SSB.

[0303] If the first cell detects that the communication terminal device needs to perform measurement on the second cell (such as RRM measurement), on-demand SSB third measurement configuration information may be sent to the communication terminal device, and on-demand SSB fourth indication information may also be sent to the second cell;

[0304] Among them, the on-demand SSB third measurement configuration information may include information such as: on-demand SSB resource configuration of the second cell, monitoring time window of the on-demand SSB of the second cell, etc.; the fourth indication information is used to indicate that the second cell needs to send an on-demand SSB on designated resources, or to indicate that the second cell sends an on-demand SSB.

[0305] This embodiment sends first measurement configuration information to the communication terminal device, and sends first indication information to the second cell to be activated; receives first measurement report information sent by the communication terminal device, and selects a target cell to be activated from the second cell to be activated according to the first measurement report information; sends first activation indication information to the communication terminal device, and sends activation request information to the target cell to be activated. Due to the improvement of various communication processes, it is ensured that the existing network communication process can be improved by using power domain and time domain technology, so that it can further save energy and improve system energy efficiency, thereby reducing the negative impact of 5G networks on the environment.

[0306] refer to Figure 3 , Figure 3 FIG. 4 is a flow chart of a second embodiment of a communication method according to the present invention.

[0307] Based on the first embodiment, the communication method of this embodiment further includes, before step S10:

[0308] Step S01: receiving cell adding indication information sent by the network, and sending second measurement configuration information to the communication terminal device.

[0309] Step S02: Receive second measurement report information sent by the communication terminal device, and determine the cell to be added according to the second measurement report information.

[0310] It should be noted that, before selecting to activate the second cell for the communication terminal device, a suitable second cell may be added as the second cell to be activated for the communication terminal device.

[0311] In actual use, the initiation of cell addition can be indicated by the network (also known as the communication base station). On this basis, if the first cell receives the cell addition indication information sent by the communication base station, it will try to start adding the corresponding second cell for the communication terminal device as the second cell to be activated. At this time, in order to ensure reasonable addition, the communication terminal device needs to perform corresponding measurements. Therefore, the second measurement configuration information can be sent to the communication terminal device.

[0312] The cell adding indication information includes at least one of the following:

[0313] Indicative information of downlink service requirements of communication terminal equipment;

[0314] Add indication information of a new second cell for the communication terminal device.

[0315] The second measurement configuration information may include at least one of the following:

[0316] The measurement-related configuration of the first cell includes at least a reference signal configuration, a measurement threshold, a cell offset parameter, and a hysteresis parameter;

[0317] The measurement-related configuration of the non-dormant neighboring cell of the first cell includes at least a reference signal configuration, a measurement threshold, a cell offset parameter, and a hysteresis parameter;

[0318] The measurement-related configuration of the dormant neighboring cell of the first cell includes at least a reference signal configuration, a measurement threshold, a cell offset parameter, and a hysteresis parameter;

[0319] location information of the first cell or a base station to which the first cell belongs;

[0320] The location information of the neighboring cell of the first cell or the base station to which the neighboring cell of the first cell belongs.

[0321] Thereafter, if the communication terminal device receives the second measurement configuration information sent by the first cell, it can perform measurements based on the configuration in the second measurement configuration information, and then send the second measurement report information to the first cell. At this time, the first cell will select the second cell that needs to be added for the communication terminal device according to the measurement report information, that is, the cell to be added. Thereafter, the cell to be added is added to the communication terminal device (such as adding it to a list, etc.), and the added cell to be added can be used as the second cell to be activated.

[0322] In actual use, the second measurement report information may include at least one of the following:

[0323] A reference signal strength of the first cell;

[0324] Distance information between the communication terminal device and the first cell reference position;

[0325] A reference signal strength of a non-dormant neighboring cell of the first cell;

[0326] Distance information between the communication terminal device and a reference position of a non-dormant neighboring cell of the first cell;

[0327] Distance information between the communication terminal device and the reference position of the dormant neighboring cell of the first cell.

[0328] In a specific implementation, the addition of a cell may also be initiated by a communication terminal device. In this case, before step S10 in this embodiment, the following may also be included:

[0329] receiving a cell adding request message sent by a communication terminal device, and sending second measurement configuration information to the communication terminal device;

[0330] Receive second measurement report information sent by the communication terminal device, and determine the cell to be added according to the second measurement report information.

[0331] It should be noted that in some cases (such as when there are specific uplink service requirements or the measurement results meet specific conditions), the communication terminal device can send a cell addition request message to the communication terminal device. At this time, if the first cell receives the cell addition indication message sent by the network, it will try to start adding the corresponding second cell for the communication terminal device as the second cell to be activated. At this time, in order to ensure reasonable addition, the communication terminal device needs to perform corresponding measurements. Therefore, the second measurement configuration information can be sent to the communication terminal device.

[0332] Thereafter, if the communication terminal device receives the second measurement configuration information sent by the first cell, it can perform measurements based on the configuration in the second measurement configuration information, and then send the second measurement report information to the first cell. At this time, the first cell will select the second cell that needs to be added for the communication terminal device according to the measurement report information, that is, the cell to be added. Thereafter, the cell to be added is added to the communication terminal device (such as added to the second cell list, etc.), and the second cell can be used as the second cell to be activated.

[0333] In actual use, the cell adding request information sent by the communication terminal device satisfies at least one of the following:

[0334] The cell adding request includes a first adding request, where the first adding request is used to inform the first cell of an uplink service demand of a communication terminal device, and / or to request the second cell to add a new second cell for the communication terminal device;

[0335] The cell adding request includes a second adding request, where the second adding request is used to inform the communication link status information between the first cell and the communication terminal device, and / or to request the second cell to add a new second cell for the communication terminal device;

[0336] The cell adding request includes a terminal buffer status report, and the terminal buffer status report is used to inform the first cell of the uplink service demand of the communication terminal equipment, and / or request the second cell to add a new second cell for the communication terminal equipment.

[0337] In order to ensure that the communication terminal device can reasonably perform measurement, so as to ensure that the sending of the cell adding request information can be reasonably triggered, before the receiving of the cell adding request information sent by the communication terminal device in this embodiment, the following may also be included:

[0338] Send the cell addition selection process configuration information to the communication terminal device.

[0339] It should be noted that the cell addition selection process configuration information is used to inform the communication terminal device of the relevant configuration information of the second cell addition process. The cell addition selection process configuration information may include at least one of the following:

[0340] Measurement-related configuration of the first cell;

[0341] Measurement-related configuration of the dormant neighbor cells of the first cell;

[0342] Measurement-related configuration of the non-dormant neighbor cells of the first cell;

[0343] Relevant configuration of the wake-up signal of the first cell;

[0344] Location information of the first cell or the base station to which the first cell belongs;

[0345] Regional information of the service area or signal coverage area of the first cell.

[0346] For the sake of easy understanding, an example is given below, but the present solution is not limited thereto. For example:

[0347] When triggered, if the communication terminal device has an uplink service requirement (such as the current serving cell of the communication terminal device cannot meet the uplink service requirement of the communication terminal device), the first WUS may be sent to the first cell. The first WUS may be the first addition request information of the second cell, and the first addition request information of the second cell is used to inform the first cell of the uplink service requirement, and / or request the first cell to add a new second cell for the communication terminal device (to process the uplink service requirement);

[0348] Or, send a BSR to the first cell. The BSR is used to inform the first cell of the uplink service requirement, and / or request the first cell to add a new second cell for the communication terminal device (to process the uplink service requirement);

[0349] Or if the communication terminal device detects that Ms + Hys1 < Thresh1, or Ms < Thresh1, the first WUS may be sent to the first cell. The first WUS may be the second addition request information of the second cell, and the second addition request information of the second cell is used to inform the first cell of the communication link status information between the communication terminal device and the first cell, and / or request the first cell to add a new second cell for the communication terminal device; or, send a BSR to the first cell. The BSR is used to inform the first cell of the communication link status information, and / or request the first cell to add a new second cell for the communication terminal device (to process the uplink service requirement);

[0350] Among them, Ms can be the measurement result of the first cell (such as RSRP, RSRQ, SINR, RSCP, EcN0 of the reference signal), or it can be the measurement result of the first cell without considering any bias; Hys1 can be 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.

[0351] Subsequently, the first cell may receive the second cell adding indication information from the network side, the first WUS sent by the communication terminal device, or the BSR sent by the communication terminal device:

[0352] If second cell adding indication information from the network side is received, the second cell adding indication information is used to indicate a downlink service demand of the communication terminal device, and / or to instruct the first cell to add a new second cell for the communication terminal device (to process the downlink service demand);

[0353] If a first WUS sent by a communication terminal device is received, the first WUS may be first adding request information of a second cell, and 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 add a new second cell for the communication terminal device (to process the uplink service demand);

[0354] If a first WUS sent by a communication terminal device is received, the first WUS may be second adding request information of a second cell, and the second adding request information of the second cell is used to inform the communication link status information between the first cell and the communication terminal device, and / or request the first cell to add a new second cell for the communication terminal device;

[0355] If a BSR sent by a communication terminal device is received, 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 add a new second cell for the communication terminal device.

[0356] At this time, if the first cell believes that it is necessary to specify the second cell to be added based on the measurement result of the communication terminal device, and / or directly send the second measurement configuration information to the communication terminal device;

[0357] The second measurement configuration information may include at least one of the following configurations:

[0358] 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;

[0359] Configuration 2: measurement-related configurations of (possibly multiple) non-dormant neighboring cells of the first cell, including but not limited to reference signal configuration, measurement threshold, cell bias parameter, and hysteresis parameter;

[0360] Configuration 3: 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;

[0369] 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.

[0370] In this embodiment, the communication method is applied to the second cell;

[0371] The communication method comprises the following steps:

[0372] Step S100: receiving first indication information sent by a first cell, and determining information sending configuration according to the first indication information.

[0373] Step S200: Send a synchronization signal block according to the information sending configuration.

[0374] It should be noted that the execution subject of this embodiment may be a communication device operating as a second cell, and the second cell may be a secondary cell in a 5G network environment, or a base station to which the secondary cell belongs. To facilitate measurement, the primary cell may send first measurement configuration information to the general terminal device, and send first indication information to each second cell to be activated.

[0375] The first indication information is used to instruct the second cell that needs to be activated for the communication terminal equipment to send an on-demand SSB (on-demand synchronization signal block) in a specified manner on specified resources; or, to request the second cell to send an on-demand SSB; the first measurement configuration information content may include information such as: 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, PCI of the on-demand SSB of the second cell, and other information.

[0376] Therefore, after receiving the first indication information, the second cell can parse the first indication information, determine the information sending configuration according to the content contained in the first indication information, and then send the synchronization signal block according to the information sending configuration to ensure that the communication terminal equipment can perform measurements.

[0377] Afterwards, the second cell may still sleep or enter a dormant state. After the second cell is subsequently activated, the communication terminal device may also send a wake-up signal to the second cell. At this time, the second cell may send a synchronization signal block according to the wake-up signal. At the same time, the control itself may be turned on, or switched to an on state. At this time, after step S200 described in this embodiment, the following may also be included:

[0378] Receiving a wake-up signal sent by a communication terminal device;

[0379] Send a synchronization signal block according to the wake-up signal, and / or turn on or switch to an on state.

[0380] In actual application, in order to ensure that the first cell can know the operating status of the second cell, while sending the synchronization signal block according to the wake-up signal, the activation notification information can also be sent to the first cell. At the same time, since the second cell may have been dormant, in order to ensure that the synchronization signal block can be sent normally, when the wake-up signal is received, the second cell can be woken up first, and then the synchronization signal block can be sent according to the wake-up signal.

[0381] The activation notification information is used to notify the first cell that the second cell is turned on or has been turned on; and the action of waking up the second cell may include at least one of the following:

[0382] Controlling the second cell to be turned on;

[0383] Adjusting the operating state of the second cell to an on state;

[0384] Control the second cell to send a synchronization signal block at a basic frequency.

[0385] In a specific implementation, the second cell may be configured to be activated relative to a certain communication terminal device. At this time, the second cell receives the activation request information sent by the first cell. At this time, the second cell may send a synchronization signal block based on the activation request information. At this time, after step S200 described in this embodiment, the following may also be included:

[0386] Receiving activation request information sent by the first cell;

[0387] Send a synchronization signal block according to the activation request information.

[0388] It should be noted that the activation request information is used to indicate that the second cell is about to be activated by a communication terminal device, instructing it to perform corresponding operations, which may include at least one of the following:

[0389] The second cell needs to send indication information of an on-demand synchronization signal block on designated resources;

[0390] Indication information indicating that the second cell needs to be turned on or needs to be switched to an on state.

[0391] Similarly, in actual use, when the second cell receives the activation indication information, it may have been dormant or has entered a dormant state. At this time, in order to ensure the normal sending of the synchronization signal block, the second cell can be awakened first, and then the synchronization signal block can be sent according to the activation request information.

[0392] When waking up the second cell, the executed action may include at least one of the following:

[0393] Controlling the second cell to be turned on;

[0394] Adjusting the operating state of the second cell to an on state;

[0395] Control the second cell to send a synchronization signal block at a basic frequency.

[0396] In a specific implementation, the second cell may try to sleep or enter a sleep state during operation, and the first cell may control part of the second cells to maintain an activated state according to actual monitoring results. At this time, the first cell sends a keep-activated indication message to the second cell. At this time, after step S200 in this embodiment, the following may also be included:

[0397] Receive the keep activation indication information sent by the first cell, and keep the second cell activated.

[0398] It should be noted that the keep activation indication information is used to indicate that the second cell remains activated or maintains an activated state. When the second cell receives the keep activation indication information sent by the first cell, it will keep the second cell (for the communication terminal device) activated or running in an activated state.

[0399] In actual use, the first cell may also send the second activation selection process configuration information to initialize the second cell activation selection process configuration through the configuration information. At this time, before or after each step described in this embodiment, the following may also be included:

[0400] Receive second activation selection process configuration information sent by the first cell.

[0401] It should be noted that, after receiving the second activation selection process configuration information sent by the first cell, the second cell can extract the corresponding configuration therefrom for caching or storage.

[0402] The second activation selection process configuration information may include at least one of the following:

[0403] resource configuration of an on-demand synchronization signal block of the second cell;

[0404] Service / coverage area information of the second cell.

[0405] It should be noted that there is communication interaction between the second cell and the first cell. In the above-mentioned embodiment describing the communication method for the first cell, the steps performed by the second cell have been described accordingly. Its specific implementation can refer to the description of any of the above-mentioned embodiments, and will not be repeated here.
