DOWNLINK TRANSMISSION METHOD IN A COORDINATED MULTI-POINT TRANSMISSION SYSTEM, NETWORK DEVICE, AND WIRELESS SYSTEM
First Claim
1. A downlink transmission method in a Coordinated Multi-Point (COMP) transmission system, characterized by comprising:
- determining, by a network device, a downlink physical resource and a downlink mapping rule corresponding to a physical downlink channel and/or a reference signal negotiated by cooperating cells; and
mapping, by the network device, the physical downlink channel and/or the reference signal to the downlink physical resource according to the downlink mapping rule in order to send the physical downlink channel and/or the reference signal to a User Equipment (UE).

Abstract
A downlink transmission method in a Coordinated Multi-Point (COMP) transmission system, a network device, and a wireless system are disclosed. The method includes: determining a downlink physical resource and a downlink mapping rule corresponding to a physical downlink channel and/or a reference signal negotiated by cooperating cells; and mapping the physical downlink channel and/or the reference signal to the downlink physical resource according to the downlink mapping rule, and sending the physical downlink channel and/or the reference signal to a User Equipment (UE). According to the method, effective coverage can be improved and the problem of mutual interference between cells can be prevented.
