Abstract

Embodiments of the present invention provide a control channel sending and receiving method, network equipment and terminal. The control channel sending method includes: sending downlink control information DCI to the terminal, the DCI carrying 2 transmission configuration information states TCI_state and 2 codewords Codeword. In this way, network devices and terminals can support Multi-TRP transmission.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a control channel sending and receiving method, network equipment and terminal. Background technique [0002] NR (New Radio, new wireless system) currently does not support multi-point transmission technology (CoMP, or Multi-TRP transmission), and downlink multi-point transmission technology includes DPS (Dynamic Transmission Point Selection), JT (Joint Transmission )Wait. Traditional Single-TRP transmission such as figure 1 and figure 2 As shown, TRP is Real Time Transport Portocol, that is, Real Time Transport Protocol. [0003] DPS (Dynamic Transmission Point Selection) in Multi-TRP transmission such as image 3 and Figure 4 shown. [0004] JT (joint transmission) in Multi-TRP transmission such as Figure 5 , Figure 6 and Figure 7 Shown: [0005] From the perspective of DCI (downlink control information) transmission, the downlink Single-TRP transmi...
