Abstract:
1. A method for transmitting control messages at a base station in a wireless communication system, the method comprising: generating one or more control message groups by grouping a plurality of control messages for at least one user equipment based on at least one criteria of whether or not uplink Acknowledgment/Negative Acknowledgement (ACK/NACK) channel indexes are allowed to be implicitly used in a corresponding control message, whether or not a user equipment the corresponding control message is intended for is able to implicitly use the uplink ACK/NACK channel indexes, a size of the corresponding control message, whether or not the corresponding control message is segmented into a predetermined number of subblocks, a Modulation and Coding Scheme (MCS) level applied to the corresponding control message, a size of the corresponding control message after applying the MCS level, and a frequency partition in which the corresponding control message is present; and transmitting the one or more control message groups, wherein control messages included in each of the one or more control message groups are equal in the at least one criteria, and wherein the one or more control message groups are transmitted on at least one of reuse-1 frequency partition and power-boosted frequency partition from among one or more frequency partitions configured for fractional frequency reuse.
