Description

Information processing method, communication device and storage medium related to neighboring cell measurement Technical Field

[0001] The present disclosure relates to the field of communication technologies, and in particular to an information processing method related to neighboring cell measurement, a communication device, a communication system, and a storage medium. Background Art

[0002] Mobility management helps achieve load balancing, improve user experience, and enhance overall system performance. For user equipment (UE) in the Radio Resource Control (RRC)_CONNECTED state, mobility management is implemented through cell handover. A UE is also known as a terminal. Whether a terminal performs a handover is controlled by the base station, but this decision depends on the terminal's measurement of neighboring cells. The terminal measures the reference signal quality of neighboring cells and reports this to the base station. Therefore, the accuracy of these measurements affects the base station's decision on whether to perform a cell handover.

Among them, the SSS in the SSB can be used as one of the reference signals for cell reselection of the connected terminal. The terminal's measurement of the neighboring cell may include: Synchronization signal reference signal receiving power (SS-RSRP), Synchronization signal reference signal receiving quality (SS-RSRQ), and Synchronization signal Signal to Interference plus Noise Ratio (SS-SINR). The base station can configure one or more measurements for the terminal, and the base station then determines whether to perform cell switching based on the measurement results of the terminal. SS-RSRP is defined as the linear power average of the SSS received RE power, reflecting the path loss of the current channel. SS-RSRQ is the ratio of the SS-RSRP and the received signal strength indicator (RSSI) of the NR system carrier. SS-RSRQ reflects and indicates the signal-to-noise ratio and interference level of the current channel quality. It can eliminate absolute measurement errors to a certain extent, achieving better accuracy than SS-RSRP measurement. SS-SINR is the ratio of the reference signal power to the interference noise power within the UE measurement bandwidth, which can reflect the current channel link quality.

[0108] A sub-band full duplex (SBD) technology has been proposed for time division duplex (TDD) systems. As shown in Figure 1B, the carrier corresponding to the TDD time unit is divided into uplink and downlink sub-bands. In Figure 1B, the uplink sub-band is represented by U, and the downlink sub-band is represented by D.

[0109] As shown in FIG. 1C , cross link interference (CLI) may include CLI between base stations and CLI of UE components.

[0110] With the introduction of SBFD technology, the carrier used for the downlink symbols of the neighboring cell may overlap with the uplink subband of the SBFD time unit of the current serving cell in the frequency domain. In this way, the U subband of the SBFD time unit of the serving cell will interfere with the downlink transmission of the SSB of the neighboring cell. In addition, the uplink transmission of the UE of the serving cell on the U subband of the SBFD time unit will affect other UEs' downlink measurement of the neighboring cell and interfere with it. Therefore, as shown in Figure 1D, the uplink transmission of UE1 on the U subband of the SBFD time unit will generate CLI for UE2's downlink measurement of the SSB of the neighboring cell. Similarly, when the serving cell does not contain an SBFD time unit and the neighboring cell contains an SBFD time unit, or when both the serving cell and the neighboring cell include SBFD time units, there will be similar CLI.

[0111] In view of this, as shown in FIG2A , an embodiment of the present disclosure provides a method for processing information related to neighbor cell measurement, which can be performed by the communication system shown in FIG1A . The method may include:

[0145] In some embodiments, the first configuration is at least used for the terminal to measure neighboring cells and / or report subband measurement results of neighboring cells according to the UL subband of the SBFD time unit at the frequency position of the SBFD time unit.

[0146] In some embodiments, if the serving cell is configured with an SBFD time unit and the neighboring cell is not configured with an SBFD time unit, measurements are performed on different subbands of the neighboring cell and / or measurement results are reported based on the subbands corresponding to the SBFD time unit of the serving cell.

[0147] In some embodiments, if the neighboring cell is configured with an SBFD time unit, regardless of whether the serving cell is configured with an SBFD time unit, different subbands of the neighboring cell may be measured and / or measurement results reported according to the subband corresponding to the SBFD time unit of the neighboring cell.

The system information block may include a master information block (MIB) and / or other system information blocks (SIBs).

[0156] In other embodiments, the network device may send an RRC message and a MAC layer control element (CE) containing configuration information.

[0157] S2102: The terminal performs measurement of neighboring cells.

[0158] In some embodiments, the terminal's measurement of the neighboring cell is related to whether at least one of the serving cell and the neighboring cell is configured with an SBFD time unit.

[0159] In some embodiments, the neighboring cell measurement is performed based on whether the serving cell and / or neighboring cell of the terminal are configured with a sub-band full-duplex (SBFD) time unit.

[0160] In some embodiments, the serving cell and / or neighboring cell of the terminal are configured with SBFD time units, and the measurement of the neighboring cells is performed according to the first configuration.

[0161] In other embodiments, neither the serving cell nor the neighboring cell of the terminal is configured with an SBFD time unit, and the measurement of the neighboring cell is performed according to the second configuration.

[0162] If the terminal serving cell has multiple BWPs, when SBFD time units are configured on some BWPs and the terminal's currently activated BWP may not be configured with SBFD time units, it is possible not to perform neighboring cell measurements based on the first configuration, but to continue using the second configuration to perform neighboring cell measurements.

[0163] If the terminal serving cell has multiple BWPs, when SBFD time units are configured on some BWPs and the terminal's currently activated BWP is not configured with SBFD time units, the measurement of neighboring cells may not be performed based on the first configuration, but the second configuration may continue to be used to perform the measurement of neighboring cells.

[0164] In some embodiments, the serving cell and / or neighboring cell of the terminal is configured with an SBFD time unit and the SBFD time unit is configured on the activated bandwidth part BWP of the terminal, and the measurement of the neighboring cell is performed according to the first configuration.

[0165] In some embodiments, the serving cell and / or neighboring cell of the terminal is configured with an SBFD time unit and the SBFD time unit is not configured on the terminal activated BWP, and neighboring cell measurement is performed according to the second configuration.

[0166] In some embodiments, if the serving cell and / or neighboring cell of the terminal is configured with an SBFD time unit and the SBFD time unit is not within the time range for the terminal to measure the neighboring cell, the neighboring cell measurement is performed according to the second configuration.

[0167] In some other embodiments, the serving cell and / or neighboring cell of the terminal is configured with an SBFD time unit, and the SBFD time unit is configured within a time range for the terminal to measure neighboring cells, and neighboring cell measurement is performed according to the first configuration.

[0168] In some embodiments, the terminal serving cell and / or the neighboring cell are configured with an SBFD time unit, and a first received signal strength indication RSSI is obtained by measuring a first subband of the neighboring cell, and a second RSSI is obtained by measuring a second subband of the neighboring cell; the second subband is different from the first subband;

[0169] Determine a first RSRQ according to the first RSSI;

[0170] A second RSRQ is determined based on the second RSSI.

[0171] In some other embodiments, the terminal serving cell is configured with an SBFD time unit, measures a first SINR transmitted in a first sub-band of a neighboring cell and measures a second SINR in a second sub-band.

[0172] For example, if the serving cell is configured with an SBFD time unit and the neighboring cell is not, the carriers of the neighboring cells are all configured as downlink bandwidth. The terminal measures the neighboring cell in sub-bands based on the uplink and downlink sub-bands corresponding to the serving cell's SBFD time unit. For example, the frequency of the first sub-band is the same as the frequency of the uplink sub-band in the serving cell's SBFD time unit. The frequency of the second sub-band is the same as the frequency of the downlink sub-band in the serving cell's SBFD time unit.

[0173] For example, if the neighboring cell is configured with an SBFD time unit and the serving cell is not, that is, the serving cell's bandwidth is fully used for uplink or downlink, the terminal measures the neighboring cell in subbands based on the uplink and downlink subbands corresponding to the serving cell's SBFD time unit. For example, the first subband is the uplink subband of the neighboring cell's SBFD time unit. The second subband is the downlink subband of the neighboring cell's SBFD time unit.

[0174] Exemplarily, if a neighboring cell is configured with an SBFD time unit and the serving cell is also configured with an SBFD time unit, that is, the serving cell has an uplink subband and a downlink subband, the terminal measures the neighboring cell in subbands based on the uplink subband and downlink subband corresponding to the SBFD time unit of the serving cell. For example, the first subband includes: a subband in the uplink subband of the neighboring cell that overlaps with the downlink subband of the serving cell, and / or a subband in the downlink subband of the neighboring cell that overlaps with the uplink subband of the serving cell. The second subband includes: a subband in the uplink subband of the neighboring cell that does not overlap with the downlink subband of the serving cell, and / or a subband in the downlink subband of the neighboring cell that does not overlap with the uplink subband of the serving cell.

[0175] In some embodiments, the terminal's measurement of neighboring cells may include at least one of the following:

[0176] Measuring the reference signal sent by the network equipment of the neighboring cell in the downlink subband;

[0177] Measure the uplink signal sent by the terminal of the neighboring cell in the uplink subband.

[0178] As shown in Figure 2C, the terminal's serving cell's BWP includes UL and DL subbands. In Figure 2C, the UL subband is represented by U, and the DL subband is represented by D. If the SSB of a neighboring cell, or the SSS of an SSB, falls within the frequency range of the serving cell's UL subband, CLI will result. In this case, the terminal can distinguish between RSSIs for the U subband and other subbands. In this case, the neighboring cell measurement unit corresponding to the serving cell's UL subband will include CLI.

[0179] S2103: The terminal sends the measurement result of the neighboring cell to the network device.

[0180] In some embodiments, the reporting of the measurement result of the neighboring cell by the terminal is related to whether the serving cell is configured with the SBFD time unit.

[0181] In some embodiments, the terminal sends the measurement results of the neighboring cells according to whether the serving cell of the terminal is configured with an SBFD time unit.

[0182] In some embodiments, the serving cell of the terminal is configured with an SBFD time unit, and the terminal reports the measurement result according to the first configuration.

[0183] In some embodiments, at least one of the serving cell and the neighboring cell of the terminal is configured with an SBFD time unit and is located on an activated BWP of the terminal, and the terminal reports the measurement result according to the first configuration.

[0185] In some embodiments, at least one of the serving cell and the neighboring cell of the terminal is configured with an SBFD time unit and is within a time range for the terminal to measure the neighboring cell, and the terminal reports the measurement result according to the first configuration.

[0186] In some embodiments, at least one of the serving cell and the neighboring cell of the terminal is configured with an SBFD time unit and is not within a time range for the terminal to measure the neighboring cell, and the terminal reports the measurement result according to the second configuration.

[0187] In some embodiments, neither the serving cell nor the neighboring cell is configured with an SBFD time unit, and the terminal reports the measurement result according to the second configuration.

[0188] In some embodiments, when periodically reporting the measurement results, the terminal sends the first RSRQ and the second RSRQ to the network device.

[0189] In some embodiments, the periods for periodically reporting measurement results of different sub-bands may be the same or different.

[0190] Exemplarily, if the periods of measurement results of different subbands are the same, when periodically reporting the measurement results, the terminal sends the first RSRQ and the second RSRQ to the network device.

[0191] For another example, if the periods of measurement results for different subbands are different, when periodically reporting the measurement results, the terminal sends a first RSRQ to the network device at the reporting time of the first period, and sends a second RSRQ to the network device at the reporting time of the second period. The first period is the period for periodic reporting of the first RSRQ. The second period is the period for periodic reporting of the second RSRQ.

[0192] In some embodiments, when periodically reporting the measurement result, the terminal sends the first SINR and the second SINR to the network device.

[0193] Exemplarily, if the periods of measurement results of different subbands are the same, when periodically reporting the measurement results, the terminal sends the first SINR and the second SINR to the network device.

[0194] As another example, if the periods of different subband measurement results are different, when periodically reporting the measurement results, the terminal sends the first SINR to the network device at the reporting time of the third period, and sends the second SINR to the network device at the reporting time of the fourth period. The third period is the period for periodic reporting of the first SINR. The fourth period is the period for periodic reporting of the second SINR.

[0195] In some embodiments, when reporting a measurement result triggered by an event due to the first RSRQ and / or the second RSRQ, the terminal sends the first RSRQ and / or the second RSRQ that caused the event to be triggered to the network device.

[0196] In some embodiments, when reporting a measurement result triggered by an event due to at least one of the first RSRQ and the second RSRQ, the terminal sends the first RSRQ and the second RSRQ to the network device.

[0197] In some embodiments, the thresholds for triggering an event by the first RSRQ and / or the second RSRQ may be the same or different.

[0198] In some embodiments, the threshold at which the first RSRQ causes an event to be triggered may be lower than the threshold at which the second RSRQ causes an event to be triggered.

[0199] In some embodiments, when reporting a measurement result in which an event is triggered by the first SINR and / or the second SINR, the terminal sends the first SINR and / or the second SINR that caused the event to be triggered to the network device.

[0200] In some embodiments, when reporting a measurement result triggered by an event caused by at least one of the first SINR and the second SINR, the terminal sends the first SINR and the second SINR to the network device.

[0201] In some embodiments, the thresholds for triggering an event by the first SINR and / or the second SINR may be the same or different.

[0202] In some embodiments, the threshold at which the first SINR triggers an event may be lower than the threshold at which the second SINR triggers an event.

[0203] It is worth noting that: in some embodiments, regardless of whether the serving cell is configured with an SBFD time unit, the network device may configure the terminal to perform RSRP and / or SINR measurement of neighboring cell carriers and / or report the measurement results.

[0204] When the above measurement results are used for cell switching, the network device can control the cell switching of the terminal according to the more accurate measurement results, and enable the terminal to switch to a more appropriate neighboring cell.

In this case, the network device cannot receive the measurement results and does not need to control the terminal's cell handover based on the measurement results.

[0366] As shown in FIG4B , an embodiment of the present disclosure provides a method for processing information related to neighbor cell measurement, where the method is performed by a network device and includes:

[0367] S4201: Send configuration information.

[0368] In some embodiments, the network device sends configuration information to the terminal.

[0369] In some embodiments, the network device sends the first configuration and / or the second configuration to the terminal.

[0372] It is worth noting that: the optional implementation of S4201 can refer to the corresponding embodiment S2201 in Figure 2B.

[0373] S4202: Receive measurement results of neighboring cells.

[0374] In some embodiments, the network device receives the measurement result of the neighboring cell sent by the terminal.

[0375] In some embodiments, the measurement result of the neighboring cell sent by the terminal is received according to the measurement result sent by the network device to the terminal.

[0379] In some embodiments, when the serving cell and / or the neighboring cell are configured with SBFD time units, the cell switching of the terminal is controlled according to the subband measurement result of the terminal.

[0380] In some embodiments, when neither the serving cell nor the neighboring cell is configured with an SBFD time unit, the cell of the terminal is switched according to the carrier measurement result of the terminal.

[0381] In some embodiments, when the serving cell and / or the neighboring cell are configured with an SBFD time unit and the SBFD time unit is located on a terminal activated BWP, the cell switching of the terminal is controlled according to the subband measurement result of the terminal.

[0382] In some embodiments, when the serving cell and / or the neighboring cell are configured with an SBFD time unit and the SBFD time unit is within a time range during which the terminal measures the neighboring cell, the cell switching of the terminal is controlled according to the subband measurement result of the terminal.

[0383] In some embodiments, cell switching of the terminal is controlled according to the first RSRQ and / or the first SINR in the subband measurement result.

[0384] In some embodiments, cell switching of the terminal is controlled according to the first RSRQ and / or the first SINR in the subband measurement result.

[0385] In some embodiments, cell switching of the terminal is controlled based on the carrier measurement result.

[0386] The specific cell switching of the terminal controlled by the network device may include but is not limited to at least one of the following:

[0387] Determining the need for cell handover of the terminal based on the measurement result;

[0388] When cell handover is required, a target cell is selected for the terminal based on the measurement results. For example, the target cell is selected based on the subband measurement results and / or carrier measurement results.

[0389] A cell handover command is sent to the cell, where the cell handover command includes a cell identifier or cell index of a target cell that the terminal determines to access. In some embodiments, the cell handover command may also include RRC reconfiguration information for the terminal to hand over to the target cell.

[0390] It is worth noting that steps S4202 and S4203 are optional. For example, if a terminal performs cell measurement according to configuration information and reports neighboring cell measurement results based on an event trigger, the terminal will not send neighboring cell measurement results unless the event is triggered. In this case, the network device cannot receive the measurement results and does not need to control the terminal's cell handover based on the measurement results.

[0391] To address the inaccurate neighbor cell measurement and reporting issues caused by CLI, improvements need to be made to the relevant technical measurement and reporting mechanisms. The relevant measurements are based on the entire measurement bandwidth, and the base station cannot know whether the measurement results are affected by CLI.

[0392] Related technology reporting types include periodic reporting and event-triggered reporting. The terminal needs to consider the impact of CLI when measuring and reporting, allowing the base station to better determine whether the terminal should perform a cell handover. Therefore, for these two types of reporting, a subband-based measurement and reporting mechanism can be added. The terminal measures the RSRP of the SSS, but the RSSI measurement is based on the subband. This allows the terminal to obtain the RSSI of frequency bands not affected by CLI and the RSSI of frequency bands affected by CLI, and further obtain separate SS-RSRQ values. The base station can determine whether the measurement results are affected by CLI by comparison, thereby better determining whether the terminal can switch to the target cell.

[0393] In addition, for event-triggered reporting, the event triggering conditions may be affected by CLI. Considering that triggering conditions different from those of related technologies can be configured in cases where CLI may be affected, the base station should configure different thresholds for the terminal. Since measurement results may be lowered due to CLI influence, the threshold for neighboring cell measurements that may be affected by CLI should be set lower than that for neighboring cell measurements that are not affected by CLI. This ensures that measurement results affected by CLI can still trigger event-triggered reporting, allowing the base station to better determine whether the terminal can switch to the target cell.

[0394] In order to truly evaluate the quality of neighboring cells, the present disclosure considers two situations:

[0395] Case 1 is that the active BWP of the terminal includes both uplink subband and downlink subband.

[0396] Case 2 is that the active BWP of the terminal includes only uplink subbands or only downlink subbands.

[0397] In some embodiments, a further case of Case 2 is that the neighboring cell is configured with an SBFD time unit on the terminal activation BWP.

[0398] In view of this, the following two solutions are proposed based on periodic reporting and event-triggered reporting:

[0399] Solution 1: For situation 1, a sub-band SS-RSRQ measurement and reporting mechanism can be used.

[0400] Solution 2: For cases 1 and 2, for event-triggered reporting, different thresholds are set for neighboring cell measurements that may be affected by CLI and neighboring cell measurements that are not affected by CLI.

[0401] For solution 1, the terminal measures SS-RSRP and separately measures the RSSI of the part within the activated BWP and overlapping uplink subbands, as well as the RSSI of the remaining part, to obtain two SS-RSRQ values, which can represent the measurement results that may be affected by CLI and the measurement results that are not affected, respectively.

[0402] For periodic reporting, the terminal may report both values ​​to the base station each time it reports, and the base station determines the quality of the neighboring cell based on the two values.

[0403] For event-triggered reporting, the terminal may trigger reporting when any measurement result meets the event triggering condition, that is, the terminal may only report the measurement result that meets the triggering condition, or report both measurement results.

[0404] In this way, the terminal measures the SS-RSRQ values ​​of the two parts and reports them. The base station can determine whether the measurement results are affected by the CLI by comparison, thereby better deciding whether the terminal can switch to the target cell.

[0405] For solution 2, events related to cell handover in neighboring cell measurement include, but are not limited to, at least one of the following events:

[0406] Event A3: The measurement result of the neighboring cell is higher than the measurement result of the special cell (SpCell) by a threshold;

[0407] Event A4: The measurement result of the neighboring cell is higher than a threshold;

[0408] Event A5: The measurement result of the SpCell is lower than threshold 1 and the measurement result of the neighboring cell is higher than threshold 2. Threshold 1 and threshold 2 are predetermined or configurable values.

[0409] Event A6: The neighbor cell measurement result is higher than the secondary cell measurement result by a threshold. This event A6 is applicable to carrier aggregation and / or dual connectivity scenarios, in which the terminal's serving cells may include a primary cell and a secondary cell.

[0410] For the above events, the neighboring cell measurement that may be affected by CLI requires a lower threshold. This is because the measurement results may be lower due to the influence of CLI, and the report that could have been triggered may not be triggered due to this influence. Therefore, two thresholds can be set for the neighboring cell measurement results: one for the measurement not affected by CLI and the other for the measurement affected by CLI.

[0411] The solution provided by the embodiment of the present disclosure can enable event-triggered reporting to be triggered even if the measurement result is affected by the CLI, so that the base station can better decide whether the terminal can be handed over to the target cell.

[0412] The embodiments of the present disclosure design a neighboring cell measurement and reporting mechanism that takes into account the impact of CLI, enhances the periodic measurement and reporting mechanism and event-triggered measurement and reporting mechanism of related technologies, takes into account the applicability of the terminal's activation BWP size to different solutions, and uses a subband-based measurement and reporting mechanism to enable the base station to determine whether it is affected by CLI by comparing different measurement results. By configuring different thresholds for event-triggered reporting, results affected by CLI also have the opportunity to trigger reporting. Based on the embodiments of the present disclosure, the base station can better determine whether the terminal can switch to the target cell.
