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...
