METHOD FOR TRANSMITTING CONTROL INFORMATION AND APPARATUS FOR SAME |
摘要 |
A method for transmitting uplink control information by a user equipment in a wireless communication system supporting carrier aggregation of a plurality of cells and operating in a time division duplex (TDD). The method according to one embodiment includes receiving, by the user equipment, downlink signals on the plurality of cells, each of the downlink signals requiring a hybrid automatic repeat request acknowledgement (HARQ-ACK) response; and transmitting, by the user equipment, the uplink control information including at least one per-cell HARQ-ACK bit for each cell in an uplink subframe via a physical uplink shared channel (PUSCH). When a reference uplink-downlink (UL-DL) configuration for performing the receiving and the transmitting belongs to a first UL-DL configuration set on each of the plurality of cells, a number of the at least one per-cell HARQ-ACK bit for each cell is determined using a value of min (W, Mc). Min (W, Mc) denotes a smallest value of W and Mc, W denotes a value indicated by 2-bit downlink assignment index (DAI) information included in downlink control information corresponding to the PUSCH, and Mc denotes a number of downlink subframes corresponding to the uplink subframe for each cell. |

1. A method for transmitting uplink control information by a user equipment in a wireless communication system supporting carrier aggregation of a plurality of cells and operating in a time division duplex (TDD), the method comprising:
receiving, by the user equipment, downlink signals on the plurality of cells, each of the downlink signals requiring a hybrid automatic repeat request acknowledgement (HARQ-ACK) response; and transmitting, by the user equipment, the uplink control information including at least one per-cell HARQ-ACK bit for each cell in an uplink subframe via a physical uplink shared channel (PUSCH), wherein, when a reference uplink-downlink (UL-DL) configuration for performing the receiving and the transmitting belongs to a first UL-DL configuration set on each of the plurality of cells, a number of the at least one per-cell HARQ-ACK bit for each cell is determined using a value of min (W, Mc), and wherein min (W, Mc) denotes a smallest value of W and Mc, W denotes a value indicated by 2-bit downlink assignment index (DAI) information included in downlink control information corresponding to the PUSCH, and Mc denotes a number of downlink subframes corresponding to the uplink subframe for each cell. |
