[0115] Fast beam scanning is one of the key technologies of beam management, which allows base stations and terminals to quickly identify and adjust the best beam to ensure effective communication connections. This technology is particularly important in, for example, millimeter wave (mmWave) frequency bands, because these frequency bands have narrow signal coverage and higher requirements for beam alignment.

[0116] In some embodiments, the objectives of reaching agreement on radio resource management (RRM) in NR are as follows:

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

[0118] Among them, for terminals that support multiple Rx simultaneous reception on a single carrier, study suitable scenarios and conditions. If feasible, the FR2-1 L3 measurement delay can be reduced by optimizing the Rx beam scanning factor. For terminals that do not support multiple Rx simultaneous reception mode, study suitable scenarios and conditions. If feasible, the carrier specific switching factor (CSSF) outside the measurement gap in the CA / DC scenario can be optimized to reduce the FR2-1 L3 measurement delay. At this time, it is assumed that the terminal has two search units (number of searchers is 2).

[0119] In some embodiments, in the connected state, one of the methods that can be used to reduce the L3 measurement delay based on FR2-1 SSB is fast beam scanning. This method can reduce the measurement delay caused by the larger 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, that is, the SSBs on each beam are different. Figure 1B FIG. 1 is a schematic diagram of SSB according to an embodiment of the present disclosure. Figure 1B As shown, in an SSB measurement timing configuration (SMTC) window, 8 SSBs with SSB indices 0 to 7 are respectively mapped to 8 different beams. The terminal detects SSBs on multiple beams within a processing window 11. For example, the terminal receives SSBs within a processing window of 3 beams. At this time, the terminal can only receive 3 SSBs with SSB indices 0, 1, and 2.

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

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

[0122] Therefore, for a terminal that supports simultaneous multi-Rx reception, how to quickly scan the beam is a problem that needs to be solved.

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

[0124] In some embodiments, the terms "processing window", "time window", "window", "period", "duration", etc. can be used interchangeably.

In one embodiment, the buffer size used by the terminal considering only single beam processing may be recorded 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 in 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 only indicates the first capability of the terminal. In one embodiment, the terminal can indicate the first capability or the third capability to the network device by whether to send the first information. In one embodiment, the terminal supports processing multiple SSBs using the first cache size, so the terminal sends the first information to the network device to indicate the first capability to the network device. In one embodiment, the terminal does not support the use of the first cache size, so step S2101 is omitted, and the terminal does not send the first information to the network device to indicate the third capability to the network device.

[0144] In some embodiments, when the first information only indicates the first capability of the terminal, the first information may include a first field and a second field, wherein the first field is used to indicate the first capability and the second field is used to indicate the first cache size.

[0146] In some embodiments, step S2101 may be omitted, in which case the first capability and the third capability of the terminal may be pre-configured or configured by default.

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

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

[0169] In some embodiments, the terminal may simultaneously receive SSBs on different beams. In one embodiment, "the terminal simultaneously receives SSBs on different beams" may 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 SSB on different beams.

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

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

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

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

[0175] In some embodiments, the terminal uses the first buffer size to process SSBs on different beams within one processing window. In one embodiment, the terminal receives SSBs on all beams within one processing window. In one embodiment, the terminal uses the first buffer size to process SSBs on all beams within one processing window.

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

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

[0178] In some embodiments, the actual duration of the measurement performed by the terminal is less than the product of the number of SSBs in an SSB burst set and the first duration, where the first duration is the measurement duration of a single beam. In other words, the actual duration of the measurement performed by the terminal is less than the measurement duration of multiple SSBs when only single beam processing is considered. In this way, by reducing the measurement duration, the measurement delay is reduced, thereby improving the measurement efficiency. In one embodiment, the terminal can complete the measurement based on SSBs on different beams within the 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 recorded 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 FR2-1 power level 3, 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, M pss / sss_sync_w / o_gaps ≤40 (if fast beam scanning is activated). In one example, for UE supporting power class 2, M pss / sss_sync_w / o_gaps ≤24 (if fast beam scanning is activated). In one example, for UE supporting power class 3, M pss / sss_sync_w / o_gaps ≤24 (if fast beam scanning is activated). In one example, the above M can be M meas_period_w / o_gapsIn one example, for a UE supporting 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 class 3, M meas_period_w / o_gaps ≤24 (if fast beam scanning is activated).

[0180] In some embodiments, during the above fast beam scanning process, the terminal needs additional processing delay (such as T_ ssbburst ). In one example, T_ ssbburst Include at least the duration of SSB bursts needed.

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

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

[0183] At this point, the fast beam scanning of the terminal supporting multiple Rx simultaneous reception is completed.

[0184] The communication method involved in the embodiment of the present disclosure may include at least one of steps S2101 to S2104.

In one embodiment, when the first information includes the first field, and the first field indicates the second capability, the first information may also include a third field. In one embodiment, the third field can be used to indicate a third cache size. In one embodiment, the value of the third field is the numerical value of the third cache size, so that the terminal can report to the network device the third cache size that can be used to receive multiple SSBs from different beams, so that the network device can determine the number of processing windows in an SMTC window according to the third cache size, and then the network device can configure multiple SSBs on different beams in each processing window for the terminal. In one embodiment, the third field can also be used to indicate the number of processing windows supported by the terminal in an SMTC window, so that the network device can configure multiple SSBs on different beams in each processing window for the terminal.

[0207] In some embodiments, the first information only indicates the second capability of the terminal. In one embodiment, the terminal may indicate the second capability or the fourth capability to the network device by whether to send the first information. In one embodiment, the terminal supports processing one or more SSBs from different beams using the third cache size in sequence, so the terminal sends the first information to the network device to indicate the second capability to the network device. In one embodiment, the terminal does not support processing one or more SSBs from different beams using the third cache size in sequence, so step S2201 is omitted, and the terminal does not send the first information to the network device to indicate the fourth capability to the network device.

[0208] In some embodiments, when the first information only indicates the second capability of the terminal, the first information may include a first field and a third field, wherein the first field is used to indicate the second capability, and the third field is used to indicate the third cache size. In one embodiment, the value of the third field is the value of the third cache size, so that the terminal can report to the network device the third cache size that can be used to receive multiple SSBs from different beams, so that the network device can determine the number of processing windows in an SMTC window according to the third cache size, and then the network device can configure multiple on different beams in each processing window for the terminal.

[0209] In some embodiments, step S2201 may be omitted, in which case the second capability and the fourth capability of the terminal may be pre-configured or configured by default. In this case, the network device and the terminal must reach a consistent understanding of the capabilities of the terminal.

[0210] In some embodiments, the terms "multiple SSBs from different beams", "SSBs on different beams", "SSBs sent on different beams", "multiple SSBs sent on different beams", etc. may be used interchangeably.

[0211] In some embodiments, terms such as "send", "transmit", "report", "send", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably.

[0212] In some embodiments, "obtain", "obtain", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be interchangeable, and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from high levels, obtaining by self-processing, autonomous implementation, etc.

[0213] In step S2202, the network device sends second information.

[0214] In some embodiments, when the first information indicates the second capability, the network device may send the second information to the terminal.

[0215] In some embodiments, when the first information indicates the first capability, the network device can determine the length of the processing window of the terminal in an SMTC window according to the first cache size, and determine the measurement configuration to 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 a measurement configuration of the terminal. In some embodiments, the measurement configuration of the terminal may include at least one of the following: a measurement configuration based on SSB, a configuration of an SSB burst set, and a configuration of multiple SSBs on different beams.

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

[0219] In one example, the configuration of the SSB burst set may include at least one of the following: a period of the SSB burst set, a 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 SSBs on different beams, the time domain position of SSBs on different beams, the frequency domain position of 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, when the first information indicates the 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, when step S2201 is omitted, the network device determines that the terminal's capability for fast beam scanning is the second capability or the fourth capability based on predefined information, default configuration information, etc. If the terminal's capability for fast beam scanning is the second capability, the network device sends the second information. If the terminal's capability for fast beam scanning is the fourth capability, the network device sends the third information.

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

[0226] In some embodiments, the second information and the third information may be carried in one or more downlink signalings. In one example, the downlink signaling 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 sends SSB on different beams.

[0229] In some embodiments, the network device sends multiple SSBs on different beams, and one SSB is mapped on each beam. In one embodiment, the 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 in multiple directions in one SSB burst set within one STMC window.

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

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

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

[0234] In some embodiments, a terminal with fast beam switching capability using pipelined windows performs measurements using multiple Rx panels.

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

[0236] In some embodiments, the terminal processes SSBs on different beams in a pipeline manner within multiple processing windows, and the number of SSBs processed in each processing window may be one or more. In one embodiment, the terminal processes one or more SSBs on different beams using a third buffer size within each processing window until all SSBs in an SSB burst set are processed. In one embodiment, the terminal processes SSBs on different beams in multiple processing windows in a pipeline manner in sequence. In one embodiment, the terminal processes SSBs on different beams using a third buffer size within multiple processing windows in a pipeline manner. In one embodiment, for multiple processing windows, the terminal processes one or more SSBs from different beams using a third buffer size within each processing window in sequence.

[0237] In one example, Figure 3B is another schematic diagram of SSB transmission according to an embodiment of the present disclosure, such as Figure 3B As shown, in one SMTC window, 8 SSBs with SSB indexes from 0 to 7 are respectively mapped to 8 different beams. The terminal processes SSBs on 3 beams (such as SSB indexes from 0 to 2) in a first processing window 32a, and then the terminal processes SSBs on 3 beams (such as SSB indexes from 3 to 5) in a second processing window 32b, and then the terminal processes SSBs on 2 beams (such as SSB indexes from 6 to 7) in a third processing window 32c.

[0238] In some embodiments, the actual duration of the measurement performed by the terminal is less than the product of the number of SSBs in an SSB burst set and the first duration, where the first duration is the measurement duration of a single beam. In other words, the actual duration of the measurement performed by the terminal is less than the measurement duration of multiple SSBs when only single beam processing is considered. In this way, by reducing the measurement duration, the measurement delay is reduced, thereby improving the measurement efficiency. In one embodiment, the terminal can complete the measurement based on SSBs on different beams within the 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 recorded 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 FR2-1 power level 3, 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, M pss / sss_sync_w / o_gaps ≤40 (if fast beam scanning is activated). In one example, for UE supporting power class 2, M pss / sss_sync_w / o_gaps ≤24 (if fast beam scanning is activated). In one example, for UE supporting power class 3, M pss / sss_sync_w / o_gaps ≤24 (if fast beam scanning is activated). In one example, the above M can be M meas_period_w / o_gaps In one example, for a UE supporting 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 class 3, M meas_period_w / o_gaps ≤24 (if fast beam scanning is activated).

[0240] In some embodiments, during the above fast beam scanning process, the terminal needs additional processing delay (such as T_ ssbburst ). In one example, T_ ssbburst Include at least the duration of SSB bursts needed.

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

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

[0243] At this point, the fast beam scanning of the terminal supporting multiple Rx simultaneous reception is completed.

[0244] The communication method involved in the embodiment of the present disclosure may include at least one of steps S2201 to S2204.
