[0115] In some embodiments of the present disclosure, the L3 measurement delay reduction in the connected mode based on a frequency range 2-1 (FR2-1) synchronization signal block (SSB) includes:
[0116] (1) For UEs supporting multi-Rx (receive antenna) simultaneous reception, appropriate scenarios and conditions can be investigated, and if feasible, the FR2-1 L3 measurement delay can be reduced by an optimized method:
[0117] Rx beam sweeping factor;
[0118] (2) For UEs not in multi-Rx simultaneous reception mode, appropriate scenarios and conditions can be investigated, and if feasible, the FR2-1 L3 measurement delay can be reduced by an optimized method:
[0119] Carrier Specific Scaling Factor (CSSF) in the out-of-gap frequency extension in the Carrier Aggregation (CA) / Dual Connectivity (DC) scenario, where the reference assumption searcher number is 2.
[0120] In the Work Item Description (WID), the scenarios to be considered when reducing L3 measurement delay are not explicitly explained. The applicant believes that at least the intra- and inter- frequency measurement requirements defined in TS 38.133 [] 9.2 and 9.3 should be reconsidered. However, for UEs not in multi-Rx simultaneous reception mode, only out-of-gap measurements need to be enhanced. Table 1 is the measurement in TS 38.133 that can be optimized.
[0121] Table 1
[0122] In some embodiments, the intra- and inter- frequency measurement requirements can be determined by the following formulas: Tidentify_intra_without_index=(T PSS / SSS_sync_intra +TSSB_measurement_period_intra) (1) Tidentify_intra_with_index=(T PSS / SSS_sync_intra +TSSB_measurement_period_ intra +T SSB_time_index_intra ) (2)
[0123] Where Tidentify_intra_without_index is the total L3 measurement delay when the terminal does not need to report SSB based on Radio Resource Management (RRM) measurement results related to SSB index, in ms, T PSS / SSS_sync_intraTo detect the duration of the Primary Synchronization Signal (PSS) and / or the Secondary Synchronization Signal (SSS), TSSB_measurement_period_intra is the measurement duration for SSB measurement; Tidentify_intra_with_index is the total L3 measurement delay when the terminal needs to report SSB based on the RRM measurement result related to SSB index, T SSB_time_index_intra To obtain the duration of SSB index.
[0124] In some embodiments, for a UE supporting power class 6 configured with highSpeedMeasFlagFR2-r17, if the measurement timing configuration (SSB-based Measurement Timing Configuration, SMTC) <= 40 ms, T PSS / SSS_sync_intra may be given in Table 9.2.5.1-11, otherwise, T PSS / SSS_sync_intra may be given in Table 9.2.5.1-2.

[0130] It should be noted that the specific content of all the tables involved above can refer to the existing protocol V18.4.0, which will not be repeated here.
[0131] In some embodiments, in Rel15, as shown in the above formula, assuming that the UE performs in order, the total L3 measurement delay includes multiple individual parts such as PSS / SSS synchronization, SSB measurement, and possible SSB index detection. Considering that the UE processes the cell search and SSB measurement in sequence, the UE needs to wait for SSB after the cell search. In order to reduce the total L3 measurement delay, the measurement can be enhanced by using buffered received data. For example, FIG. 1B is a measurement schematic diagram according to an embodiment of the present disclosure. As shown in FIG. 1B, the UE can first buffer the SSB for PSS detection and / or SSS detection, and then the UE can use the buffered SSB for offline measurement after PSS detection and / or SSS detection, SSB index detection. If the Rx beam index of the UE is determined to be 1, then the SSB measurement can be based on the first SSB. Therefore, the offline measurement procedure for SSB measurement after PSS / SSS synchronization and SSB time index can be studied.
[0132] In some embodiments, for a New Radio (NR) system, in a radio resource control (RRC) connected state with carrier aggregation and multiple component carriers (CCs), because the SSB symbol to be measured can be the same symbol buffered when the UE performs cell search (PSS / SSS), the cell search and measurement for an intra-frequency cell can be performed in parallel and independently.
[0133] In some embodiments, the embodiments of the present disclosure can be applied in NR and 6G.
[0134] FIG. 2A is an interaction diagram illustrating a communication method according to an embodiment of the present disclosure. The method can be performed by the communication system described above. As shown in FIG. 2A, the method can include the following steps.
[0135] In step S2101, the network device sends second information to the terminal.
[0136] In some embodiments, the second information can be used to indicate whether the terminal reports SSB based on RRM measurement results related to SSB index.
[0137] In some embodiments, the second information can be used to indicate that the terminal reports SSB based on RRM measurement results related to SSB index.
[0138] In some embodiments, the second information can be used to indicate that the terminal does not report SSB based on RRM measurement results related to SSB index.
[0139] In some embodiments, "the terminal reports SSB based on RRM measurement results related to SSB index" can be understood as that the terminal needs to perform SSB measurement after detecting SSB index.
[0140] In some embodiments, "the terminal does not report SSB based on RRM measurement results related to SSB index" can be understood as that the terminal does not need to perform SSB measurement after detecting SSB index, i.e., the terminal can perform SSB measurement before detecting SSB index, or can perform SSB measurement at the same time as detecting SSB index, which is not limited in the embodiments of the present disclosure.
[0141] In some embodiments, the name of the second information is not limited, for example, it can be "reporting indication information", "reporting SSB indication information", "SSB reporting type indication information", etc.
[0142] In step S2102, the terminal performs SSB measurement in the case of performing cell search.
[0143] In some embodiments, the cell search can include at least one of the following: PSS detection, SSS detection, SSB index detection.
[0144] In some embodiments, the terminal can first perform PSS detection and / or SSS detection, and then perform SSB index detection.
[0145] In some embodiments, the cell search needs to receive N receive beams, and the SSB measurement needs M beams, N > M, and N and M are positive integers.
[0146] In some embodiments, "the cell search needs to receive N receive beams" can be understood as that the terminal is in a multi-receive antenna mode.
[0147] In some embodiments, if the terminal determines that there is no indication to report SSB based on RRM measurement results related to SSB index, the terminal can not need to wait for the detection result of SSB index when performing SSB measurement.
[0148] In some embodiments, the terminal can perform SSB measurement in the PSS detection and / or SSS detection process.
[0149] In some embodiments, the terminal can use the same received data offline when performing SSB measurement as when performing cell search.
[0150] In some embodiments, "performing SSB measurement in the PSS detection and / or SSS detection process" can be understood as starting SSB measurement at the same time as starting PSS detection and / or SSS detection, or can be understood as performing SSB measurement after a period of time after starting PSS detection and / or SSS detection, and the embodiments of the present disclosure do not limit this.
[0151] In some embodiments, the terminal can perform SSB measurement according to first information, which can include measurement reference signal information cached by the terminal before the first time when performing cell search.
[0152] In some embodiments, the "first time" can be the current time, or a historical time from the current time, for example, the first time can be the time of the last cell search, and the embodiments of the present disclosure do not limit this.
[0153] In some embodiments, the first information can include measurement reference signal information cached by the terminal in the last cell search.
[0154] In some embodiments, "the last cell search" can be understood as the last cell search before the current time, for example, the last cell search can be the cell search performed by the last SSB, and as shown in FIG. 1B, the reference signal information used by the second SSB measurement can be the measurement reference signal information cached when performing cell search by the first SSB.
[0155] In some embodiments, when performing cell search, the terminal can cache the measurement reference signal information of the current cell search for use in the next SSB measurement.
[0156] In some embodiments, the measurement reference signal information can be the SSB symbol to be measured.
[0157] For example, the SSB symbol to be measured when the terminal performs SSB measurement can be the symbol cached by the terminal when performing cell search by the last SSB.
[0158] In some embodiments, the terminal performing SSB measurement according to the buffered measurement reference signal information can be understood as that the terminal performs SSB measurement offline.
[0159] In some embodiments, the cell search and the SSB measurement are performed in parallel and independently.
[0160] In some embodiments, the terminal can perform SSB measurement when the cell search is performed and the cell and the beam index are identified.
[0161] In some embodiments, the cell or the beam index identified by the terminal can be identified in the last cell search.
[0162] In some embodiments, “identifying the cell and the beam index” can be understood as that the terminal has completed a cell search, and can also be understood as that the measurement reference signal information has been buffered.
[0163] In step S2103, the terminal determines the maximum allowed delay of SSB measurement according to the first time length and the second time length, when the second information does not indicate that the SSB is reported based on the RRM measurement result related to the SSB index.
[0164] In some embodiments, after the terminal receives the second information sent by the network device, the terminal can determine whether to report the SSB based on the RRM measurement result related to the SSB index according to the second information.
[0165] In some embodiments, if the second information does not indicate that the terminal reports the SSB based on the RRM measurement result related to the SSB index, the terminal determines that the SSB does not need to be reported based on the RRM measurement result related to the SSB index.
[0166] In some embodiments, “the second information does not indicate that the terminal reports the SSB based on the RRM measurement result related to the SSB index” can be understood as that reportQuantityRsIndexes or maxNrofRSIndexesToReport is not configured.
[0167] In some embodiments, the first time length can be a measurement period of SSB measurement.
[0168] In some embodiments, the second time length can be a time length for PSS / SSS detection.
[0169] In some embodiments, the terminal starts PSS / SSS detection and SSB measurement simultaneously, if the duration of PSS / SSS detection is less than the measurement period of SSB measurement, i.e., PSS / SSS detection is completed before SSB measurement, the maximum allowed delay of SSB measurement can be the measurement period of SSB measurement; if the duration of PSS / SSS detection is greater than the measurement period of SSB measurement, i.e., SSB measurement is completed before PSS / SSS detection, the maximum allowed delay of SSB measurement can be the duration of PSS / SSS detection.
[0170] In some embodiments, the maximum of the first duration and the second duration can be taken as the maximum allowed delay of SSB measurement.
[0171] For example, the maximum allowed delay of SSB measurement can be calculated by the following formula: Tidentify_intra_without_index=max(T PSS / SSS_sync_intra ,TSSB_measurement_period_intra) (3)
[0172] Wherein, Tidentify_intra_without_index is the maximum allowed delay of SSB measurement, TSSB_measurement_period_intra is the first duration, T PSS / SSS_sync_intra is the second duration.
[0173] In some embodiments, if the terminal does not indicate to report SSB based on RRM measurement results related to SSB index, the terminal can identify a new detectable intra-frequency cell within Tidentify_intra_without_index, or the terminal is indicated that the neighbor cell is synchronized with the serving cell (deriveSSB-IndexFromCell is enabled).
[0174] In some embodiments, for FR1 TDD (Time Division Duplexing) and FR2 with SCS less than or equal to 480 kHz, deriveSSB-IndexFromCell is always enabled.
[0175] With the above method, the terminal can perform SSB measurement in the cell search process, so that when the terminal does not indicate to report SSB based on RRM measurement results related to SSB index, the maximum allowed delay of SSB measurement is the maximum of the duration of detecting PSS and / or detecting SSS and the measurement period of SSB measurement, thereby reducing the maximum allowed delay of SSB measurement.
[0176] The method related to the embodiments of the present disclosure can include at least one of the steps S2101-S2103. For example, the step S2101 can be implemented as an independent embodiment, the step S2102 can be implemented as an independent embodiment, the step S2103 can be implemented as an independent embodiment, and the steps S2102 and S2103 can be implemented as an independent embodiment.
[0177] In some embodiments, the steps S2101-S2103 are optional steps. For example, the step S2101 is optional, and one or more of the steps can be omitted or replaced in different embodiments.
[0178] In some embodiments, other optional implementations described before or after the description of FIG. 2A can be referred to.
[0179] FIG. 2B is an interaction diagram of a communication method according to an embodiment of the present disclosure. The method can be performed by the communication system described above. As shown in FIG. 2B, the method can include:
[0180] In step S2201, the network device sends second information to the terminal.
[0181] Optional implementations of the step S2201 can be referred to optional implementations of the step S2101 of FIG. 2A and other associated parts in the embodiments related to FIG. 2A, which will not be described herein.
[0182] In step S2202, the terminal performs SSB measurement in the case of performing cell search.
[0183] Optional implementations of the step S2202 can be referred to optional implementations of the step S2102 of FIG. 2A and other associated parts in the embodiments related to FIG. 2A, which will not be described herein.
[0184] In step S2203, the terminal determines the maximum allowed delay of SSB measurement according to the first time length, the second time length and the third time length according to the second information indicating the reporting of SSB based on the RRM measurement result related to the SSB index.
[0185] In some embodiments, after the terminal receives the second information sent by the network device, the terminal can determine whether the terminal is instructed to report SSB based on the RRM measurement result related to the SSB index according to the second information.
[0186] In some embodiments, if the second information instructs the terminal to report SSB based on the RRM measurement result related to the SSB index, the terminal determines that it is necessary to report SSB based on the RRM measurement result related to the SSB index.
[0187] In some embodiments, the first time length is a measurement period of SSB measurement, the second time length is a time length of detecting PSS and / or detecting SSS, and the third time length is a time length of detecting SSB index.
[0188] In some embodiments, the terminal can start SSB measurement at the same time when starting detecting PSS and / or detecting SSS. If the time length of detecting PSS and / or detecting SSS and detecting SSB index is less than the measurement period of SSB measurement, i.e., the detecting of PSS and / or detecting of SSS and detecting of SSB index are all completed before the SSB measurement is completed, the maximum allowed delay of SSB measurement can be the measurement period of SSB measurement. If the time length of detecting PSS and / or detecting SSS and detecting SSB index is greater than the measurement period of SSB measurement, i.e., the detecting of PSS and / or detecting of SSS is not completed after the SSB measurement is completed, or the detecting of SSB index is not completed after the SSB measurement is completed, the maximum allowed delay of SSB measurement can be the sum of the time length of detecting PSS and / or detecting SSS and the time length of detecting SSB index.
[0189] In some embodiments, the maximum of the fourth time length and the first time length can be taken as the maximum allowed delay of SSB measurement, wherein the fourth time length is the sum of the second time length and the third time length.
[0190] For example, the maximum allowed delay of SSB measurement can be calculated by the following formula: Tidentify_intra_with_index=max(T PSS / SSS_sync_intra +T SSB_time_index_intra ,TSSB_measurement_period_intra) (4)
[0191] wherein T SAB_time_index_intra is the third time length.
[0192] In some embodiments, if the terminal needs to report SSB based on RRM measurement result related to SSB index, the terminal can identify a new detectable SSB block of the detected same-frequency cell within Tidentify_intra_with_index.
[0193] By using the above method, the terminal can perform SSB measurement in the cell search process. Thus, when the terminal needs to report SSB based on RRM measurement result related to SSB index, the maximum allowed delay of SSB measurement is the maximum of the time length of PSS / SSS detection and SSB index detection and the measurement period of SSB measurement, thereby reducing the maximum allowed delay of SSB measurement.
[0194] The method related to the embodiments of the present disclosure can include at least one of the steps S2201-S2203. For example, the step S2201 can be implemented as an independent embodiment, the step S2202 can be implemented as an independent embodiment, the step S2203 can be implemented as an independent embodiment, and the steps S2202+S2203 can be implemented as an independent embodiment.
