Abstract:
1. A method of a first relay performing Cooperative Multiple Points Transmission and Receptions (CoMP), the method comprising: receiving, by the first relay, scheduling information and first data from a base station; receiving, by the first relay, a bypass indicator from the base station; performing, by the first relay, protocol layer processing for the scheduling information and the first data; and transmitting, by the first relay, the processed first data to a user equipment (UE) based on the processed scheduling information, wherein the bypass indicator is information instructing that the protocol layer processing be performed for only some protocol layers included in the first relay, and wherein, if the first relay is scheduled to transmit the processed first data simultaneously with second data transmitted by a second relay to the UE and if the first relay has more protocol layers than those of the second relay, the bypass indicator instructs the first relay to perform protocol layer processing for only protocol layers corresponding to protocol layers processed by the second relay.
