METHOD FOR TRANSMITTING CONTROL INFORMATION AND DEVICE FOR SAME

摘要

The present invention relates to a wireless communication system. In more detail, the present invention relates to a method for transmitting uplink control information in a wireless communication system operating as TDD, and a device for same. The method includes transmitting Hybrid Automatic Repeat request—Acknowledgement (HARQ) in a subframe n through Physical Uplink Control Channel (PUCCH), and a transmission power of the PUCCH relates to a method determined using Equation 4 or 5, and a device for same.

1. A method for transmitting uplink control information in a TDD (Time Division Duplex) wireless communication system, the method comprising:
transmitting, by a mobile terminal to a base station (BS), a HARQ-ACK (Hybrid Automatic Repeat reQuest-Acknowledgement) signal via a PUCCH (Physical Uplink Control Channel) in an uplink (UL) subframe in accordance with a PUCCH transmission power parameter determined by the mobile terminal according to an UL-DL (Uplink-Downlink) configuration and a modulo equation that includes the following parameters: a number of cells configured for the mobile terminal; a downlink assignment index number assigned by the BS; a total number of downlink scheduling-related PDCCHs (Physical Downlink Control Channels) detected; a number of HARQ-ACK bits corresponding to a configured downlink transmission mode on a serving cell c, and one of:
a number of PDCCH or PDSCH (Physical Downlink Shared Channel) without a corresponding PDCCH received when bundling is applied, ora number of transport blocks or a SPS (Semi-Persistent Scheduling) release PDCCH received by the mobile terminal when bundling is not applied.
