Wireless communication system using multiple transmission and reception points
First Claim
1. A method of wireless communication, the method comprising:
- obtaining a first cell identifier;
obtaining a second cell identifier;
receiving first scrambled bits of first control information through a first control channel;
descrambling the first scrambled bits at least based on the first cell identifier;
receiving second scrambled bits of second control information through a second control channel; and
wherein descrambling the second scrambled bits at least based on the second cell identifier,wherein the second control channel is different from the first control channel and the first cell identifier is different from the second cell identifier.

Abstract
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.
