US 2016/0261385 A1 · METHOD FOR TRANSMITTING CONTROL INFORMATION AND APPARATUS FOR SAME

Abstract

A wireless communication system is disclosed. A method for transmitting uplink control information in a wireless communication system supporting carrier aggregation and operating in TDD includes: generating a first HARQ-ACK (hybrid automatic repeat request-acknowledgement) set for a first cell using a value M; generating a second HARQ-ACK set for a second cell using the value M; and transmitting a bit value corresponding to a third HARQ-ACK set including the first HARQ-ACK set and the second HARQ-ACK set in an uplink subframe n, wherein M=max(M1, M2), max(M1, M2) representing a value being equal to or larger than not smaller between M1 and M2, wherein M1 corresponds to the number of downlink subframes corresponding to the uplink subframe n in the first cell, and M2 corresponds to the number of downlink subframes corresponding to the uplink subframe n in the second cell, wherein the first cell and the second cell have different UL-DL configurations.

Dependent claims

A method for transmitting uplink control information by a user equipment (UE) in a wireless communication system supporting carrier aggregation, the UE being configured with a plurality of cells including a first cell and a second cell and configured to transmit a hybrid automatic repeat request-acknowledgment (HARQ-ACK) response based on channel selection, the first cell and the second cell having different uplink-downlink (UL-DL) configurations and operating in time division duplex (TDD), the method comprising:

determining a value M as a largest value of M1 or M2, M1 being a value according to an UL-DL configuration of the first cell and M2 being a value according to an UL-DL configuration of the second cell;
determining HARQ-ACK responses for the first cell and the second cell based on the value M;
determining bit values and a physical uplink control channel (PUCCH) resource corresponding to the determined HARQ-ACK responses;
and
transmitting the bit values using the PUCCH resource in an uplink subframe.
