Problems solved by technology

However, the energy-saving signal is a kind of PDCCH, and the PDCCH is transmitted in the control resource set (CORESET). Currently, a CORESET has only one transmission configuration indication (TCI) configuration, that is, only one beam direction, so it can only be transmitted in one beam. To receive an energy-saving signal carried by a CORESET, the transmission robustness of the energy-saving signal cannot be guaranteed

Abstract

The invention provides a TCI state configuration method and device for an energy-saving signal, and belongs to the technical field of wireless communication. The TCI state configuration method of theenergy-saving signal is applied to network side equipment and comprises any one of the following steps that TCI state configuration information of a control resource set is sent to a terminal, the control resource set is associated with the energy-saving signal of the terminal and / or associated with a search space of the energy-saving signal, and the TCI state configuration information comprises at least one TCI state; and a corresponding relationship between an energy-saving signal detection opportunity and / or a search space detection opportunity of the energy-saving signal and a synchronization signal / physical broadcast channel block SS / PBCH block is pre-defined through high-level signaling configuration and / or a protocol. Through the technical scheme of the invention, the energy-savingsignal can realize a wave beam scanning function, and the transmission robustness is improved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and device for configuring a TCI state of an energy-saving signal. Background technique [0002] In related technologies, a power saving signal (power saving signal) is proposed to trigger a terminal energy saving solution to reduce unnecessary terminal behavior and terminal energy consumption. One of the functions of the energy-saving signal is to indicate whether the terminal detects a physical downlink control channel (Physical Downlink Control Channel, PDCCH) in an associated discontinuous reception (Discontinuous Reception, DRX) period. [0003] After the energy-saving signal is introduced, the terminal first detects the energy-saving signal to determine whether to wake up to receive other PDCCHs in the corresponding DRX cycle, so the energy-saving signal must ensure high robustness. However, the energy-saving signal is a kind of PDCCH, and the PDCCH...
