Wireless communication system using multiple transmission and reception points

摘要

Disclosed is a wireless communication system using multiple transmission and reception points. In a wireless communication system having a first transmission and reception point and at least one second transmission and reception point belonging to the same cell, the first transmission and reception point has a wider transmission area than the at least one second transmission and reception point, and the first transmission and reception point and the at least one second transmission and reception point generate downlink transmission signals by using the same physical layer cell ID or virtual cell IDs allocated to each terminal, and then the terminals generate uplink transmission signals by using the allocated virtual cell IDs.

主权项

1. A method of receiving control data by a terminal from a transmitter, the method comprising:
receiving a synchronization signal from the transmitter to determine a physical cell identity of the transmitter; receiving information indicating a virtual cell identity of the transmitter from the transmitter; receiving first scrambled control data from the transmitter through a first control channel, wherein the first scrambled control data is scrambled based on the physical cell identity of the transmitter; receiving second scrambled control data from the transmitter through a second control channel, wherein the second scrambled control data is scrambled based on the virtual cell identity of the transmitter, and the second control channel is different from the first control channel.
