AI Technical Summary

Technical Problem

The existing 5G NR protocol assumes that the terminal can only support one TCI state CORESET, which cannot effectively handle the PDCCH listening problem with different QCL-typeD attributes between multiple TCI states, resulting in inflexible and unstable system communication.

Method used

When the terminal supports CORESETs configured with two TCI states, the flexibility and stability of system communication are ensured by listening to PDCCH in M ​​CORESETs associated with two TCI states and/or N CORESETs associated with one TCI state.

Benefits of technology

Effective monitoring of PDCCH under multiple TCI states was achieved, improving the communication flexibility and robustness of the system.

Abstract

本申请实施例公开了一种监听方法与装置、终端和网络设备；该方法包括：若在活跃下行带宽部分BWP上重叠的PDCCH监听时机中监听的PDCCH候选关联的CORESET中存在M个关联2个TCI状态的CORESET和N个关联1个TCI状态的CORESET，则终端在M个关联2个TCI状态的CORESET和 / 或N个关联1个TCI状态的CORESET中监听PDCCH，M为大于或等于1的整数，N为大于或等于0的整数，从而在终端支持被配置2个TCI状态的CORESET的情况下实现在关联2个TCI状态CORESET和 / 或关联1个TCI状态的CORESET中监听PDCCH，从而保证系统通信的灵活性、鲁棒性和稳定性。
