Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G, or a combination of 5G and 6G).

[0115] Fast beam scanning is a key technology in beam management, allowing base stations and terminals to quickly identify and adjust the optimal beam to ensure effective communication connectivity. This technology is particularly important in bands such as millimeter wave (mmWave) because these bands have narrower signal coverage and require more precise beam alignment.

[0116] In some embodiments, consensus is reached on radio resource management (RRM) in NR with the following objectives:

[0117] In the connected state, the L3 (layer 3) measurement delay based on FR2-1 SSB is reduced.

[0118] For terminals supporting simultaneous reception of multiple Rx beams on a single carrier, suitable scenarios and conditions are investigated. If feasible, FR2-1 L3 measurement delay can be reduced by optimizing factors such as the Rx beam scanning factor. For terminals not supporting simultaneous reception of multiple Rx beams, suitable scenarios and conditions are investigated. If feasible, FR2-1 L3 measurement delay can be reduced by optimizing the carrier-specific switching factor (CSSF) outside the measurement gap in the CA / DC scenario. In this case, it is assumed that the terminal has two search units (the number of searchers is 2).

[0119] In some embodiments, in the connected state, one method to reduce L3 measurement delay based on FR2-1 SSB is fast beam scanning. This method can reduce measurement delay caused by a large Rx beam scanning factor. For example, the terminal can measure multiple beams in the same SSB burst set, where different SSBs are mapped to different beams, i.e., the SSBs on each beam are different. Figure 1B is a schematic diagram of an SSB according to an embodiment of the present disclosure. As shown in Figure 1B, in an SSB measurement timing configuration (SMTC) window, eight SSBs with SSB indices from 0 to 7 are mapped to eight different beams. The terminal detects SSBs on multiple beams within a processing window 11. For example, if the terminal receives SSBs within a processing window of three beams, then the terminal can only receive the three SSBs with SSB indices of 0, 1, and 2.

[0120] In some embodiments, some SSBs in the same SSB burst set may be mapped to the same beam, meaning that different SSBs may be mapped to the same beam.

[0121] However, since the terminal processing window depends on the terminal implementation itself. For example, the terminal processing window often considers single-beam processing. Therefore, in terms of the terminal's processing capabilities (such as cache limitations, power consumption limitations, etc.), it is not feasible to perform fast secondary cell (SCell) activation through multi-beam scanning within a single SMTC window.

[0122] Therefore, for terminals that support simultaneous reception of multiple Rx signals, how to perform rapid beam scanning is a problem that needs to be solved.

[0123] In some embodiments, the terms "beam," "carrier," "SSB beam," etc., may be used interchangeably. In some embodiments, the terms "fast beam scanning," "fast beam switching," etc., may be used interchangeably.

[0124] In some embodiments, the terms “processing window,” “time window,” “window,” “time period,” “duration,” etc., may be used interchangeably.

[0132] In some embodiments, to handle multiple SSBs from different beams, the first buffer size may be larger than the buffer size used by the terminal considering only single-beam processing. In one embodiment, the buffer size used by the terminal considering only single-beam processing may be denoted as the second buffer size. In one embodiment, the second buffer size is the buffer size used by the terminal to perform processing based on multiple SSBs from a single beam. In one embodiment, the second buffer size is equal to the buffer size used by the terminal to process a single beam. In one embodiment, the second buffer size is equal to the buffer size used by the terminal during single-beam processing.

[0133] In some embodiments, the first buffer size is larger than the buffer size used by the terminal to perform measurements based on multiple SSBs from a single beam. In one embodiment, the first buffer size is larger than the buffer size used by the terminal to process a single beam.

[0143] In some embodiments, the first information indicates only a first capability of the terminal. In one embodiment, the terminal can indicate either a first capability or a third capability to the network device by whether or not it sends the first information. In one embodiment, the terminal supports processing multiple SSBs using a first buffer size; in this case, the terminal sends the first information to the network device to indicate the first capability.

[0144] In some embodiments, where the first information only indicates the terminal's first capability, the first information may include a first field and a second field, wherein the first field indicates the first capability and the second field indicates the first buffer size. In one embodiment, the value of the second field is a numerical value of the first buffer size, so that the terminal can report to the network device the first buffer size it can use to receive multiple SSBs from different beams, allowing the network device to configure multiple SSBs on different beams for the terminal based on the second field.

[0145] In some embodiments, the network device can determine the length of the terminal's processing window based on the first buffer size sent by the terminal, and then configure multiple SSBs on different beams in the processing window.

[0146] In some embodiments, step S2101 can be omitted. In this case, the terminal's first and third capabilities can be pre-configured or default-configured. In this situation, the network device and the terminal must reach a consensus on the terminal's capabilities.

[0152] In some embodiments, when the first information indicates a first capability, the network device can determine the length of the processing window of the terminal within an SMTC window based on the first buffer size, and determine the measurement configuration for the terminal.

[0154] In some embodiments, the second information is used to indicate the measurement configuration of the terminal. In some embodiments, the measurement configuration of the terminal may include at least one of the following: SSB-based measurement configuration, SSB burst set configuration, and multiple SSBs on different beams.

[0165] In some embodiments, the terms "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0166] In some embodiments, the terms "uplink", "uplink", and "physical uplink" can be used interchangeably, as can the terms "downlink", "downlink", and "physical downlink", as well as the terms "sidelink", "sidelink", "sidelink communication", "sidelink communication", "direct connection", "direct link", "direct communication", and "direct link communication".

[0167] In step S2103, the network device transmits SSB on different beams.

[0168] In some embodiments, the network device transmits multiple SSBs on different beams, with one SSB mapped to each beam. In one embodiment, SSBs on different beams belong to the same SSB burst set.

[0169] In some embodiments, the terminal can simultaneously receive SSBs on different beams. In one embodiment, "the terminal simultaneously receives SSBs on different beams" can be understood as the terminal receiving SSBs on different beams within one STMC window.

[0170] In some embodiments, the terminal uses multiple Rx panels to simultaneously receive SSBs on different beams.

[0171] In step S2104, within a processing window, the terminal performs measurements based on the SSBs on different beams.

[0172] In some embodiments, the terminal processes multiple received SSBs within a processing window to perform measurements based on these SSBs.

[0173] In some embodiments, a terminal with the capability to perform fast beam switching using a first buffer size performs measurements using multiple Rx panels.

[0174] In some embodiments, after receiving SSBs on all beams, the terminal can perform measurements based on these SSBs. In one embodiment, within a processing window, the terminal performs L3 measurements based on multiple SSBs from different beams.

[0175] In some embodiments, the terminal processes SSBs on different beams using a first buffer size within a processing window. In one embodiment, the terminal receives SSBs on all beams within a processing window. In another embodiment, the terminal processes SSBs on all beams using a first buffer size within a processing window.

[0176] In some embodiments, the cache size used by the terminal is positively correlated with the size of the terminal's processing window. The larger the first cache size used by the terminal, the larger the corresponding length of the terminal's processing window. In one embodiment, the length of the processing window corresponding to the first cache size may be less than or equal to the length of an SMTC window.

[0177] In one example, Figure 3A is another schematic diagram of SSB transmission according to an embodiment of the present disclosure. As shown in Figure 3A, in one SMTC window, eight SSBs with SSB indices from 0 to 7 are mapped to eight different beams. The terminal processes the SSBs on all beams within a processing window 31, that is, the terminal processes the eight SSBs with SSB indices from 0 to 7 within one processing window.

[0178] In some embodiments, the actual measurement duration performed by the terminal is less than the product of the number of SSBs in an SSB burst set and a first duration, where the first duration is the measurement duration for a single beam. In other words, the actual measurement duration performed by the terminal is less than the measurement duration for multiple SSBs considering only single-beam processing. Thus, by reducing the measurement duration, measurement latency is reduced, thereby improving measurement efficiency. In one embodiment, the terminal can complete measurements based on SSBs on different beams within a second duration. The second duration is less than the product of the number of SSBs and the first duration. In one example, the number of SSBs on different beams can be M, and the first duration is denoted as T_. SMTC The second duration T < M × T_ SMTC .

[0179] In some embodiments, when fast beam scanning is activated, the value of M is less than or equal to 40. In one example, when the terminal supports power level 1 or 5 on FR2-1, M ≤ 40. In some embodiments, when fast beam scanning is activated, the value of M is less than or equal to 24. In one example, when the terminal supports power level 2, M ≤ 24. In one example, when the terminal supports power level 3 on FR2-1, M ≤ 24. In one example, the above M can be M pss / sss_sync_w / o_gap In one example, for a UE supporting FR2-1 power level 1 or 5, Mpss / sss_sync_w / o_gaps ≤ 40 (if fast beam scanning is activated). In one example, for a UE supporting power level 2, Mpss / sss_sync_w / o_gaps ≤ 24 (if fast beam scanning is activated). In one example, for a UE supporting power level 3, Mpss / sss_sync_w / o_gaps ≤ 24 (if fast beam scanning is activated). In one example, M can be M... meas_period_w / o_gapsIn one example, for a UE that supports FR2-1 power level 1 or 5, M meas_period_w / o_gaps ≤40 (if fast beam scanning is activated). In one example, for a UE supporting FR2-1 power level 3, M meas_period_w / o_gaps ≤24 (if Fast Beam Scan is activated).

[0180] In some embodiments, during the aforementioned fast beam scanning process, the terminal requires additional processing latency (such as T_). ssbburst In one example, T_ ssbburst This includes at least the duration of the SSB bursts needed.

[0181] In some embodiments, SSB measurements within an SMTC have an extended processing delay (e.g., requiring at least approximately the duration of the SSB burst).

[0182] In some embodiments, after completing the measurement, the terminal can send the measurement results to the network device so that the network device can perform SCell activation.

[0183] This completes the fast beam scanning for terminals that support simultaneous reception of multiple Rx signals.

[0215] In some embodiments, when the first information indicates a first capability, the network device can determine the length of the processing window of the terminal within an SMTC window based on the first buffer size, and determine the measurement configuration for the terminal. Based on this, the network device can send second information to the terminal to indicate the measurement configuration.

[0216] In some embodiments, the terminal receives second information.

[0217] In some embodiments, the second information is used to indicate the measurement configuration of the terminal. In some embodiments, the measurement configuration of the terminal may include at least one of the following: SSB-based measurement configuration, SSB burst set configuration, and multiple SSBs on different beams.

[0218] In one example, an SSB-based measurement configuration may include parameters such as measurement period and measurement interval.

[0219] In one example, the configuration of the SSB burst set may include at least one of the following: the period of the SSB burst set, the maximum number of SSBs in the SSB burst set, etc.

[0220] In one example, the configuration of multiple SSBs on different beams may include at least one of the following: the number of SSBs on different beams, the period of the SSBs on different beams, the time-domain position of the SSBs on different beams, the frequency-domain position of the SSBs on different beams, etc.

[0221] In some embodiments, the name of the second information is not specifically limited. For example, it can be configuration information, SSB configuration information, SSB burst configuration information, multi-SSB configuration information, multi-beam SSB configuration information, measurement configuration information, etc.

[0222] In some embodiments, where the first information indicates a third capability, the network device may send third information to the terminal to indicate the configuration of multiple SSBs based on single-beam processing.

[0223] In some embodiments, the name of the third information is not specifically limited. For example, it can be configuration information, SSB configuration information, single-beam SSB configuration information, etc.

[0224] In some embodiments, if step S2201 is omitted, the network device determines whether the terminal's ability to perform fast beam scanning is a second capability or a fourth capability based on predefined information, default configuration information, etc. If the terminal's ability to perform fast beam scanning is a second capability, the network device sends second information. If the terminal's ability to perform fast beam scanning is a fourth capability, the network device sends third information.

[0225] In some embodiments, step S2202 is omitted when the network device sends third information.

[0226] In some embodiments, the second and third information may be carried in one or more downlink signaling messages. In one example, the downlink signaling message may include at least one of the following: RRC signaling, MAC CE, DCI, PDCCH signaling, PDSCH signaling, etc.

[0227] In some embodiments, the names of the first information, second information, third information, etc., are not limited to the names described in the embodiments.

[0228] In step S2203, the network device transmits SSB on different beams.

[0229] In some embodiments, the network device transmits multiple SSBs on different beams, with one SSB mapped to each beam. In one embodiment, SSBs on different beams belong to the same SSB burst set.

[0230] In some embodiments, the terminal can simultaneously receive SSBs on different beams. In one embodiment, "simultaneous reception" means that the terminal can receive beams from multiple directions within a single SSB burst set within a STMC window.

[0231] In some embodiments, the terminal uses multiple Rx panels to simultaneously receive SSBs on different beams.

[0232] In step S2204, within multiple processing windows, the terminal performs measurements in a pipeline manner based on the SSB on different beams.

[0233] In some embodiments, the terminal processes multiple received SSBs in a pipeline manner within multiple processing windows to achieve measurements based on these SSBs.

[0234] In some embodiments, a terminal with the capability for rapid beam switching using a pipelined window performs measurements using multiple Rx panels.

[0235] In one embodiment, after receiving multiple SSBs from different beams, the terminal can perform measurements on these SSBs in multiple batches using the same buffer size. In another embodiment, the terminal performs L3 measurements based on multiple SSBs from different beams within multiple processing windows.

[0236] In some embodiments, the terminal processes SSBs on different beams in a pipelined manner within multiple processing windows, and the number of SSBs processed in each processing window can be one or more. In one embodiment, the terminal uses a third buffer size to process one or more SSBs on different beams within each processing window until all SSBs in an SSB burst set have been processed. In one embodiment, the terminal processes SSBs on different beams sequentially in a pipelined manner within multiple processing windows. In one embodiment, the terminal uses a third buffer size in a pipelined manner within multiple processing windows. In one embodiment, for multiple processing windows, the terminal sequentially uses a third buffer size to process one or more SSBs from different beams within each processing window.

[0237] In one example, Figure 3B is another schematic diagram of SSB transmission according to an embodiment of the present disclosure. As shown in Figure 3B, in an SMTC window, eight SSBs with SSB indices from 0 to 7 are mapped to eight different beams. The terminal processes SSBs on three beams (e.g., SSB indices from 0 to 2) in a first processing window 32a, then processes SSBs on three beams (e.g., SSB indices from 3 to 5) in a second processing window 32b, and then processes SSBs on two beams (e.g., SSB indices from 6 to 7) in a third processing window 32c.

[0238] In some embodiments, the actual measurement duration performed by the terminal is less than the product of the number of SSBs in an SSB burst set and a first duration, where the first duration is the measurement duration for a single beam. In other words, the actual measurement duration performed by the terminal is less than the measurement duration for multiple SSBs considering only single-beam processing. Thus, by reducing the measurement duration, measurement latency is reduced, thereby improving measurement efficiency. In one embodiment, the terminal can complete measurements based on SSBs on different beams within a second duration. The second duration is less than the product of the number of SSBs and the first duration. In one example, the number of SSBs on different beams can be M, and the first duration is denoted as T_. SMTC The second duration T < M × T_ SMTC .

[0239] In some embodiments, when fast beam scanning is activated, the value of M is less than or equal to 40. In one example, when the terminal supports power level 1 or 5 on FR2-1, M ≤ 40. In some embodiments, when fast beam scanning is activated, the value of M is less than or equal to 24. In one example, when the terminal supports power level 2, M ≤ 24. In one example, when the terminal supports power level 3 on FR2-1, M ≤ 24. In one example, the above M can be M pss / sss_sync_w / o_gap In one example, for a UE supporting FR2-1 power level 1 or 5, Mpss / sss_sync_w / o_gaps ≤ 40 (if fast beam scanning is activated). In one example, for a UE supporting power level 2, Mpss / sss_sync_w / o_gaps ≤ 24 (if fast beam scanning is activated). In one example, for a UE supporting power level 3, Mpss / sss_sync_w / o_gaps ≤ 24 (if fast beam scanning is activated). In one example, M can be M... meas_period_w / o_gaps In one example, for a UE that supports FR2-1 power level 1 or 5, Mmeas_period_w / o_gaps ≤40 (if fast beam scanning is activated). In one example, for a UE supporting FR2-1 power level 3, M meas_period_w / o_gaps ≤24 (if Fast Beam Scan is activated).

[0240] In some embodiments, during the aforementioned fast beam scanning process, the terminal requires additional processing latency (such as T_). ssbburst In one example, T_ ssbburst This includes at least the duration of the SSB bursts needed.

[0241] In some embodiments, SSB measurements within an SMTC have an extended processing delay (e.g., requiring at least approximately the duration of an SSB burst).

[0242] In some embodiments, after completing the measurement, the terminal can send the measurement results to the network device so that the network device can perform SCell activation.

[0243] This completes the fast beam scanning for terminals that support simultaneous reception of multiple Rx signals.
