In addition, a plurality of system combinations (e.g., LTE or a combination of LTE-a and 5G, etc.) may be applied.

For a better understanding of the disclosed embodiments, first, the following describes related scenarios by some exemplary embodiments:

In some embodiments, if the terminal is instructed to report SSB-based radio resource management (RRM, radio Resource Management) measurements with associated Synchronization Signal Block (SSB) index SIGNAL AND PBCH block, the terminal should be able to identify a new detectable inter-frequency SSB for an already detected cell within T _{identify_inter_with_index}.

T_{identify_inter_with_index}＝(T_{PSS/SSS_sync_inter}+T_{SSB_measurement_period_inter}+T_{SSB_time_index_inter})ms

Wherein the above formula indicates that the terminal needs to sequentially perform 3 steps to detect a new cell, for example, primary synchronization signal (PSS, primary Synchronization Signal) or secondary synchronization signal (SSS, secondary Synchronization Signal) detection, SSB index detection and SSB-based measurement, corresponding to times T _{PSS/SSS_sync_inter}、T_{SSB_measurement_period_inter} and T _{SSB_time_index_inter}, respectively.

In some embodiments, the terminal needs to scan the received signal using a different receive beam at each step of PSS/SSS detection, SSB index detection, and SSB-based measurement. Illustratively, the total delay to complete PSS/SSS detection, SSB index detection, and SSB-based measurements may be very large with a receive beam scan factor of 8.

In some embodiments, for Frequency range 2 (FR 2) L3 measurements of the new cell, the terminal needs to perform receive beam scanning for PSS/SSS detection, SSB index detection, and SSB-based measurements.

In some embodiments, please refer to table one, the requirements for PSS/SSS synchronization are defined as follows:

time period of PSS/SSS detection (frequency range FR 2)

In some embodiments, mpss/sss_sync_inter=64 samples for terminals supporting FR2-1 power class 1 or 5 for Mpss/sss_sync_inter. For terminals supporting FR2-1 power class 2, mpss/sss_sync_inter=40 samples. For terminals supporting FR2-1 power class 3, mpss/sss_sync_inter=40 samples. For terminals supporting FR2-1 power class 4, mpss/sss_sync_inter=40 samples.

In some embodiments, taking FR2-1 power class 1 or 5 as an example, the terminal will first perform automatic gain control (AGC, automatic Gain Control) and time tracking based on SSB (e.g., based on 3 samples). The terminal will then proceed to perform SSB-based PSS/SSS detection for 5 samples. For each sample in FR2, the terminal needs to perform 8 RX beam scans. Then for PSS/SSS synchronization, the total number of measurements in the related art is 8×8=64. However, since the terminal may obtain some a priori information of the receive beams (which may also be referred to as RX beams, which may be interchanged, not limited herein) based on AGC and timing tracking, the terminal does not need 8 receive beams for PSS/SSS detection. The total latency of Mpss/sss_sync_inter can be reduced.

Fig. 2a is an interactive schematic diagram illustrating a cell detection method according to an embodiment of the disclosure. As shown in fig. 2a, embodiments of the present disclosure relate to a cell detection method for a communication system 100, the method comprising:

In some embodiments, the first information is used to indicate: the terminal uses different receive beams for scanning capabilities of the received signals.

In some embodiments, the first information is used to indicate: the terminal uses different receive beams to scan the received signals at a scan rate.

Step S2102: the terminal determines the detection capabilities and/or detection behavior of the terminal.

In some embodiments, the detection capability is a capability of the terminal to perform a cell detection operation.

Illustratively, T _{identify_inter_with_index}＝(T_{PSS/SSS_sync_inter}+T_{SSB_measurement_period_inter}+T_{SSB_time_index_inter}) ms.

Where T _{PSS/SSS_sync_inter} corresponds to the time of synchronization of the synchronization signal, T _{SSB_measurement_period_inter} corresponds to the time of SSB index detection, and T _{SSB_time_index_inter} corresponds to the time of SSB-based measurement.

In some embodiments, a first time at which the terminal performs the cell detection operation is determined based on the first information.

In some embodiments, the synchronization signal synchronization comprises: a first operation and a second operation; the first operation comprises Automatic Gain Control (AGC) and/or time frequency tracking, and the second operation is synchronous signal detection; based on the first information, it is determined that the terminal performs a first sub-receive beam scan factor associated with the first operation.

In some embodiments, the synchronization signal synchronization comprises: a first operation and a second operation; the first operation comprises Automatic Gain Control (AGC) and/or time frequency tracking, and the second operation is synchronous signal detection; based on the first information, determining that the terminal performs a second sub-receive beam scanning factor associated with the second operation.

In some embodiments, the first sub-receive beam scan factor is different from the second sub-receive beam scan factor.

In some embodiments, the first sub-receive beam scan factor is greater than the second sub-receive beam scan factor.

Illustratively, for PSS/SSS synchronization, there are two sub-steps: AGC/timing tracking (corresponding to the first operation) and PSS/SSS detection (corresponding to the second operation). In a scheme different from the present disclosure, it is assumed that the same reception beam scanning factor (e.g., 8) is set for both steps. If the terminal supports new faster beam scanning capabilities, the receive beam scanning factors of the two sub-steps may be set to be different, i.e. the receive beam scanning factor for the second step (e.g. PSS/SSS detection) may be less than 8.

It should be noted that the reason for the above example is that after the reception beam scanning in the first step, the terminal determines which reception beam is most suitable for the new cell. Then for the next PSS/SSS detection, fewer receive beams may be applied since the terminal already has information of the receive beam based on the previous AGC and time frequency tracking. For example, the receive beam scan factor may be reduced to 5. Then the total SSB samples will be 3×8+5×5=49 samples. Note that here 5 is just one example of a receive beam scan factor. Then the total samples will be reduced from 64 samples to 49 samples. Assuming that the SSB-based measurement timing configuration (SMTC, an SSB-based measurement timing configuration) period is 160 ms, the reduced cell detection time is 15×160 ms=2400 ms.

In some embodiments, information of a reception beam of the terminal performing the second operation is determined based on information of a reception beam of the terminal performing the first operation.

In some embodiments, a second time at which the terminal performs the first operation and a third time at which the terminal performs the second operation are determined, respectively, based on the first information.

Illustratively, separate delays (i.e., a second time and a third time) are specified for AGC and PSS/SSS detection, respectively.

In some embodiments, a fourth time is determined based on the first information, the fourth time including a time at which the terminal performed the first operation and performed the second operation.

Illustratively, a total delay (i.e., a fourth time) is specified for AGC and PSS/SSS detection.

In some embodiments, the SSB-based measurement comprises: a third operation and a fourth operation; the third operation includes automatic gain control, AGC, and/or time frequency tracking, and the fourth operation is SSB-based measurement; based on the first information, determining that the terminal performs a third sub-receive beam scanning factor associated with the third operation.

In some embodiments, the SSB-based measurement comprises: a third operation and a fourth operation; the third operation includes automatic gain control, AGC, and/or time frequency tracking, and the fourth operation is SSB-based measurement; based on the first information, determining that the terminal performs a fourth sub-receive beam scan factor associated with the fourth operation.

In some embodiments, the third sub-receive beam scan factor is different from the fourth sub-receive beam scan factor.

In some embodiments, the third sub-receive beam scan factor is greater than the fourth sub-receive beam scan factor.

In some embodiments, information of the reception beam of the terminal performing the fourth operation is determined based on information of the reception beam of the terminal performing the third operation.

In some embodiments, a fifth time for the terminal to perform the third operation and a sixth time for the terminal to perform the fourth operation are determined based on the first information, respectively.

In some embodiments, a seventh time is determined based on the first information, the seventh time including a time when the terminal performs the third operation and performs the fourth operation.

In some embodiments, the cell detection operation is a cell detection operation for a different frequency range 2FR 2.

The received beam scan factor is illustrated below by some exemplary embodiments, but is not limited thereto.

For example, please refer to table two, which shows an inter-frequency measurement applied to a band gap:

In some embodiments, N may be: n=3×8+5×n2, where N2 is the receive beam scan factor used for the time index detection step.

In some embodiments, fewer receive beam scan factors may be applied if the receive beam scan information has been reduced in the previous step.

For example, please refer to table five, SSB index detection and SSB-based measurements applied in inter-frequency measurements with gaps or inter-frequency measurements with NCSG:
