[0189] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0190] In some embodiments, the access network device may be a single device, or may be multiple devices or a group of devices, each including all or part of a first network element, a second network element, etc. The network element may be virtual or physical. The network device may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0191] In some embodiments, a core network device may be a device including one or more network elements, or may be multiple devices or device groups, each including all or part of the one or more network elements.

[0192] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. 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 proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0193] The following embodiments of the present disclosure may be applied to the communication system 100 shown in Figure 1, or a portion thereof, but are not limited thereto. The entities shown in Figure 1 are illustrative only. The communication system may include all or part of the entities shown in Figure 1, or may include other entities outside of Figure 1. 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.

[0194] The embodiments of the present disclosure may 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), other systems utilizing random access, and next-generation systems based on and extending these systems.

[0195] The 5G spectrum used in communications systems is divided into two frequency ranges (FRs): FR1 and FR2. FR1 covers a frequency range of 450 MHz to 6 GHz, also known as the sub-6 GHz band. FR2 covers a frequency range of 24.25 GHz to 52.6 GHz, also known as millimeter wave (mmWave).

[0196] The network periodically configures synchronization signal blocks (SSBs) for the secondary cell (SCell). The SSB is always in a signaling state, which consumes a lot of network (NW) power. With technological advancements, the SSB may no longer be in a signaling state. Instead, the SSB may be configured for the SCell when needed, a process called on-demand SSB.

[0197] Layer 1 (L1) RSRP measurements for SCells are performed under synchronized conditions. For on-demand SSBs, the SSBs are not always in a signaling state. Before performing the L1 RSRP measurement configured for the SCell, the SSBs may be absent for a period of time, causing the UE to lose synchronization. In this case, there is no solution for performing L1 RSRP measurements for the SCell.

[0198] Therefore, the present application proposes a method for determining the time synchronization conditions for performing L1-RSRP measurement of SCell in the case of on-demand SSB, and performing new time tracking for time synchronization in the case of time asynchrony.

[0269] In some embodiments, if the first duration is greater than a second threshold, a third duration for synchronization is determined.

[0270] In some embodiments, if the time interval between the start time of measuring L1-RSRP by the terminal and the time when the last reference signal for timing is received before measuring L1-RSRP is greater than a second threshold, it is determined that time synchronization is not maintained and additional time tracking needs to be performed for time synchronization.

[0275] The DRX cycle is greater than a third threshold, and the fourth cycle is determined to be a third duration, wherein the fourth cycle is obtained based on the DRX cycle and the first scaling factor, or based on the DRX cycle and the second scaling factor.

[0276] In some embodiments, if the DRX cycle is not configured, the third duration is determined to be the configured L1-RSRP measurement period (also described as the L1-RSRP reporting period (T Report )) and the maximum value in the first period, where the first period is obtained based on the period of the reference signal and the first scaling factor. Optionally, the duration of the first period is equal to the product of the first scaling factor and the duration of the period of the reference signal.

[0277] Optionally, the reference signal is used for time synchronization.

[0278] For example, if the reference signal is SSB, the first period = first scaling factor * T SSB , T ReportThe third duration is the larger of the first and second periods.

[0279] For example, if the reference signal is CSI-RS, the first period = first scaling factor * T CSI-RS , T Report The third duration is the larger of the first and second periods.

[0280] In some embodiments, if the configured DRX cycle is less than or equal to the third threshold, the third duration is determined to be the configured L1-RSRP measurement period (also described as the L1-RSRP reporting period (T Report )) and the maximum value of the second cycle, the second cycle is obtained based on the third cycle and the second scaling factor. Optionally, the third cycle is the DRX cycle (T DRX ) and the maximum value in the period of the reference signal.

[0281] Optionally, the reference signal is used for time synchronization.

[0282] In some embodiments, the third threshold may be specified by a protocol, for example, the third threshold is 320 ms.

[0283] In some embodiments, if the DRX cycle is less than or equal to the third threshold, and the DRX cycle is greater than the reference signal cycle, the third cycle is the DRX cycle, and the duration of the second cycle is equal to the product of the second scaling factor and the duration of the DRX cycle. Report and the larger of the second period as the third duration.

[0284] For example, if the reference signal is SSB, and T DRX >T SSB , then the second period = second scaling factor * T DRX .

[0285] For example, if the reference signal is CSI-RS, and T DRX >T CSI-RS , then the second period = second scaling factor * T DRX .

[0286] In some embodiments, if the DRX cycle is less than or equal to the third threshold, and the DRX cycle is less than the reference signal cycle, the third cycle is the reference signal cycle, and the duration of the second cycle is equal to the product of the second scaling factor and the duration of the reference signal cycle. Report The larger of the second period is used as the third duration. For example, if the reference signal is SSB, and T SSB >T DRX , then the second period = second scaling factor * T SSB .

[0287] For example, if the reference signal is CSI-RS, and T CSI-RS >T DRX , then the second period = second scaling factor * T CSI-RS .

[0288] In some embodiments, if the DRX cycle is greater than a third threshold, the fourth cycle is used as the third duration, where the duration of the fourth cycle is equal to the product of the first scaling factor and the duration of the DRX cycle, or the product of the second scaling factor and the duration of the DRX cycle.

[0289] For example, if the reference signal is SSB and SSB belongs to FR1, the fourth period = the first scaling factor * T SSB .

[0290] For example, if the reference signal is SSB and SSB belongs to FR2, then the fourth period = the second scaling factor * T SSB .

[0291] For example, if the reference signal is CSI-RS, the fourth period = first scaling factor * T DRX .

[0292] In some embodiments, the first scaling factor and the second scaling factor are related to the number of periods of a reference signal used for time synchronization.

[0293] In some embodiments, the number of periods of the reference signal used for time synchronization may be increased or decreased based on the first scaling factor, thereby changing the total duration of the period of the reference signal. Optionally, the period of the SSB (T SSB ) or the period of CSI-RS (T CSI-RS ) quantity.

[0294] In some embodiments, the number of DRX cycles may be increased or decreased based on the first scaling factor, thereby changing the total duration of the DRX cycle.

[0300] In some embodiments, the second duration includes a duration for time synchronization and a duration for measurement.

[0301] In some embodiments, L1-RSRP may be measured after time synchronization. In this case, the total duration of L1-RSRP measurement may be determined to include the duration used for time synchronization and the duration used for measurement. Optionally, the total duration of L1-RSRP measurement is the sum of the duration used for time synchronization and the duration used for measurement.

[0302] In some embodiments, if the reference signal used for L1-RSRP measurement includes: a first reference signal and a second reference signal, then the second duration includes any one of the following:

[0306] A duration for time synchronization is determined based on the second reference signal and a duration for measurement is determined based on the first reference signal.

[0307] In some embodiments, the specific method of determining the duration for time synchronization can refer to the various implementation methods of determining the third duration described above, and will not be repeated here.

[0308] In some embodiments, the specific manner of determining the duration for measurement may refer to various implementations of determining the duration for measuring L1-RSRP based on provisions of existing relevant protocols in a synchronous situation, and will not be described in detail.

[0447] If the time interval between the last SSB or CSI-RS and the L1-RSRP measurement / report configuration (which may correspond to the first duration above) is less than or equal to [x] ms (which may correspond to the first threshold or the second threshold above), time synchronization is still maintained and the UE does not need to perform additional time tracking.
