[0098] 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. 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).

[0099] 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.

[0100] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0101] 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).

[0102] In NR, especially in frequency range 2, since high-frequency channels attenuate quickly, communication based on beam transmission and reception is required to ensure coverage.

[0103] In some embodiments, communication is performed by configuring a beam measurement report based on periodic, semi-persistent, or aperiodic reporting through a base station.

[0104] However, the base station's configured reporting period length, or the timing of aperiodic reporting, may not be optimal for changes in beam quality. For example, if the period length is too short, the optimal K (K is an integer greater than or equal to 1) beams reported twice may be the same, resulting in wasted signaling overhead. If the period length is too long, beam changes may occur before the reporting time, preventing reporting, thus affecting communication quality.

[0105] Based on this, an embodiment of the present disclosure proposes a communication method, so that the terminal can report based on trigger conditions when reporting the beam, thereby avoiding the problem of waste of signaling overhead due to too frequent beam reporting, and avoiding the problem of affecting communication quality due to untimely beam reporting.

[0368] This embodiment also provides a communication method, where the terminal measures and determines whether the trigger time is met, and only reports the beam when the trigger time is met, thereby reducing signaling overhead and ensuring timely reporting when the beam quality changes.

[0369] In some embodiments, the terminal receives indication information, where the indication information is used to indicate a triggering event, and the triggering event is used to trigger a beam report.

[0370] In some embodiments, the triggering event includes at least one of the following: the current beam is below a threshold; the candidate beam is above a threshold; the candidate beam is higher than the current beam by an offset; the best K beams are different from the best K beams in the last report in at least one way or do not include the best beam reported in the last report, or the best K beams do not include the beam most recently indicated by the base station; in the case of group based beam reporting, the K groups are different from the K groups in the last report; in the case of beam group based reporting, the beam value in the last reported group changes, and the change exceeds a threshold.

[0383] RRC signaling configures trigger events, as well as thresholds and offsets related to the trigger events. The terminal then reports when the trigger event is met;

[0384] RRC signaling configures the trigger event, as well as related thresholds, offsets, etc., and then further uses MAC CE activation or DCI indication before the terminal reports when the trigger event is met.

[0385] In some embodiments, an association relationship may also be configured during RRC configuration, such as a trigger event and related thresholds or offsets and reference signal resources or resource sets (including CMR and / or IMR, reference signal resources may be reference signal resources that are sent periodically, semi-persistently, or non-periodically), and an association with the reported measurement quantity L1-RSRP or L1-SINR, reporting type (semi-persistent, or non-periodic transmission report), reporting method (whether it is a group-based beam report, which is used for simultaneous uplink transmission, and / or simultaneous downlink reception. This can be a base station configuration, or the terminal reports it itself), and an associated ID, then the MAC CE or DCI can directly activate or indicate the ID.
