The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0090] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1a, or a portion thereof, but are not limited thereto. The entities shown in FIG1a are illustrative only. The communication system may include all or a portion of the entities shown in FIG1a, or may include other entities other than those shown in FIG1a. The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0091] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0092] To better understand the embodiments of the present disclosure, first, some exemplary embodiments are used to illustrate relevant scenarios.

[0093] In some embodiments, if the terminal is instructed to report SSB-based Radio Resource Management (RRM) measurements with an associated Synchronization Signal and PBCH block index, then the terminal should be able to identify a new detectable inter-frequency SSB of an already detected cell within Tidentify_inter_with_index. Tidentify_inter_with_index = (T PSS / SSS_sync_inter +TSSB_measurement_period_inter+T SSB_time_index_inter )ms

[0094] Among them, the above formula shows that the terminal needs to perform three steps in sequence to detect the 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, and the corresponding time is T PSS / SSS_sync_inter , TSSB_measurement_period_inter and T SSB_time_index_inter .

[0095] In some embodiments, for PSS / SSS synchronization, the terminal needs to perform two sub-steps: AGC and T / F tracking, and PSS / SSS detection.

[0096] In some embodiments, for SSB measurement, the terminal performs two sub-steps: AGC and T / F tracking, and SSB-based measurement.

[0097] In the above example, the terminal will perform redundant automatic gain control (AGC) and time-frequency (T / F) tracking in two steps, so the total delay will be very long.

[0098] In some embodiments, for L3 measurements of new inter-frequency cells, the terminal needs to perform additional AGC and T / F tracking compared to intra-frequency cells. Tables 1 and 2 define the samples used for intra-frequency and inter-frequency PSS / SSS synchronization: 5 samples for intra-frequency and 8 samples for inter-frequency. Therefore, an additional 3 samples are defined in the AGC and inter-frequency T / F tracking specifications.

[0099] Table 1: Measurement period for gapless co-frequency measurement (FR1, Frequency range 1)

[0100] Table 2: PSS / SSS detection time period (frequency range FR1)

[0101] In some embodiments, for inter-frequency measurement, the terminal performs PSS / SSS synchronization, SSB index acquisition and cell measurement in sequence.

[0102] In some embodiments, for PSS / SSS detection and cell measurement, the terminal will perform redundant AGC and T / F tracking twice, and the two steps define 8 samples.

[0103] In some embodiments, please refer to Table 3, which shows the measurement period (FR1) of the inter-frequency measurement to be gapped.

[0104] Table 3 Measurement period of inter-frequency measurement with gap

[0105] It should be noted that, since the terminal has already performed AGC and T / F tracking in the PSS / SS synchronization step, the terminal does not need to additionally perform AGC and T / F tracking again for the measurement step.

[0106] FIG2a is an interactive schematic diagram of a cell detection method according to an embodiment of the present disclosure. As shown in FIG2a, the embodiment of the present disclosure relates to a cell detection method for a communication system 100, the method comprising:

[0107] Step S2101: The terminal determines the first result.

[0108] In some embodiments, during the cell detection process, the terminal determines the first result.

[0109] In some embodiments, the first result is a result of the terminal performing automatic gain control (AGC) and / or time-frequency tracking (T / F tracking) during the synchronization signal synchronization process.

[0110] In some embodiments, the first result is a result that the terminal does not perform automatic gain control AGC and / or time-frequency tracking during the synchronization signal synchronization process.

[0111] In some embodiments, the cell detection process may include synchronization signal synchronization, synchronization signal block SSB index detection and SSB-based measurement in sequence.

[0112] It should be noted that synchronization signal synchronization may also be referred to as synchronization signal detection in some scenarios, which is not limited here.

[0113] Step S2102: The terminal determines the capability and / or operation of performing cell detection.

[0114] In some embodiments, the capability is the capability of the terminal to perform a cell detection operation.

[0115] In some embodiments, the behavior is the behavior of the terminal performing a cell detection operation.

[0116] In some embodiments, the operations include at least one of the following:

[0117] Synchronization signal synchronization, wherein the synchronization signal includes a primary synchronization signal PSS and / or a secondary synchronization signal SSS;

[0118] Synchronization signal block SSB index detection;

[0119] SSB-based measurements.

[0120] In some embodiments, synchronization signal synchronization, synchronization signal block SSB index detection and SSB-based measurement can be performed sequentially.

[0121] In some embodiments, the terminal can identify a new inter-frequency cell that can be detected within Tidentify_inter_with_index.

[0122] For example, Tidentify_inter_with_index=(T PSS / SSS_sync_inter +TSSB_measurement_period_inter+T SSB_time_index_inter )ms.

[0123] Among them, T PSS / SSS_sync_inter Corresponds to the time of synchronization signal synchronization, TSSB_measurement_period_inter corresponds to the time of SSB index detection, T SSB_time_index_inter Corresponds to the time of SSB-based measurement.

[0124] In some embodiments, the process of performing cell detection includes performing at least one operation (which may also be understood as a behavior in some scenarios), and whether to perform the operation may be determined based on the capability.

[0125] In some embodiments, during the cell detection process, the terminal determines a capability and / or operation of the terminal to perform cell detection based on the first result.

[0126] In some embodiments, the first result is a result of whether the terminal has executed or not executed automatic gain control AGC and / or time-frequency tracking during the synchronization signal synchronization process.

[0127] In some embodiments, the terminal determines whether to perform AGC and / or time-frequency tracking during the SSB measurement process based on the first result.

[0128] In some embodiments, the terminal determines that the terminal has performed automatic gain control AGC and / or time-frequency tracking during the synchronization signal synchronization process, and the terminal may not perform AGC and / or time-frequency tracking during the SSB measurement process.

[0129] In some embodiments, in response to determining that the terminal has performed automatic gain control AGC and / or time-frequency tracking during the synchronization signal synchronization process, or in the case of determining that the terminal has performed automatic gain control AGC and / or time-frequency tracking during the synchronization signal synchronization process, the terminal may not perform AGC and / or time-frequency tracking during the SSB measurement process.

[0130] It should be noted that, if it is determined that the terminal has performed automatic gain control AGC and / or time-frequency tracking during the synchronization signal synchronization process, the result of the terminal performing automatic gain control AGC and / or time-frequency tracking can be directly applied to the process of the terminal performing SSB-based measurement, so that the terminal does not perform AGC and / or time-frequency tracking during the SSB measurement process, thereby reducing the cell detection time.

[0131] In some embodiments, it is determined that the terminal does not perform automatic gain control AGC and / or time-frequency tracking during synchronization of the synchronization signal, and AGC and / or time-frequency tracking are performed during measurement of the SSB by the terminal.

[0132] In some embodiments, in response to determining that the terminal does not perform automatic gain control AGC and / or time-frequency tracking during the synchronization signal synchronization process or in the case where it is determined that the terminal does not perform automatic gain control AGC and / or time-frequency tracking during the synchronization signal synchronization process, AGC and / or time-frequency tracking are performed during the measurement process of performing SSB.

[0133] In some embodiments, the time for the terminal to perform cell detection is determined based on the second result.

[0134] It should be noted that the terminal needs to complete the cell detection within the time for performing the cell detection.

[0135] In some embodiments, the second result is a result of the terminal performing or not performing AGC and / or time-frequency tracking during the SSB measurement process.

[0136] In some embodiments, the time of the cell detection is a measurement period in which the terminal performs SSB-based measurement.

[0137] In some embodiments, a second result is determined; and based on the second result, a measurement period for the terminal to perform SSB measurement is determined.

[0138] In some embodiments, it is determined that AGC and / or time-frequency tracking is not performed during the measurement of SSB, and the measurement period is determined.

[0139] In some embodiments, the measurement period does not include time for performing AGC and / or time-frequency tracking.

[0140] It should be noted that, since the measurement period does not include the time for performing AGC and / or time-frequency tracking, the time for performing cell detection can be shortened.
