Abstract

The invention discloses a transmission method of transmission configuration indication (TCI), network side equipment and terminal equipment The method comprises the following steps: selecting at leastone TCI state from a plurality of configured candidate TCI states to establish a TCI state table from Link type, a channel, an RS type or a CORESET, wherein the TCI state table comprises a corresponding relation between a TCI state and an RS set, or comprises a corresponding relation between the TCI state and the RS set and a quasi-co-location QCL type, or comprises a corresponding relation between the TCI state and a channel type; and sending the TCI state table and the link type, the channel, the RS type or the CORESET identifier corresponding to the TCI state table. According to the invention, the corresponding TCI state table is established based on the link type, the channel, the RS type or the CORESET, so that the TCI state table can be configured according to the requirements of the application scene to meet the TCI state indication requirements under different scenes.

Description

technical field [0001] The present invention relates to the communication field / terminal equipment field, and in particular to a TCI transmission method, network side equipment and terminal equipment. Background technique [0002] Long Term Evolution (LTE) / Enhanced Long Term Evolution (LTE-Advanced, LTE-A) and other wireless access technology standards are based on Multiple-Input Multiple-Output (MIMO) technology + orthogonal It is built on the basis of Orthogonal Frequency Division Multiplexing (OFDM) technology. Among them, the MIMO technology utilizes the spatial freedom obtained by the multi-antenna system to improve the peak rate and the utilization rate of the system spectrum. In the process of standardization development, the dimensions of MIMO technology continue to expand. In LTE Rel-8, up to 4 layers of MIMO transmission can be supported; in Rel-9, MU-MIMO technology is enhanced, and the transmission mode (Transmission Mode, TM)-8 MU-MIMO (Multi-User MIMO) transm...
