METHOD AND APPARATUS FOR TRANSMITTING CONTROL INFORMATION IN A WIRELESS COMMUNICATION SYSTEM

摘要

A wireless communication system is disclosed. Disclosed herein are methods for transmitting a physical uplink control channel (PUCCH) signal in a wireless communication system, which includes setting transmit power for the PUCCH signal, and an apparatus thereof. If the PUCCH signal is transmitted on a subframe configured for a scheduling request (SR), the PUCCH signal includes one or more hybrid automatic repeat request acknowledgement (HARQ-ACK) bits and an SR bit. When determining the transmit power for the PUCCH, the SR bit is selectively considered depending on whether or not a transport block for an uplink shared channel (UL-SCH) is present in the subframe.

1. A method for transmitting a physical uplink control channel (PUCCH) signal by a communication apparatus in a wireless communication system, the method comprising:
setting transmit power for the PUCCH signal, wherein, if the PUCCH signal is transmitted on a subframe configured for a scheduling request (SR), the PUCCH signal includes one or more hybrid automatic repeat request acknowledgement (HARQ-ACK) bits and an SR bit, and wherein the transmit power for the PUCCH is determined by using the following equation:h(·)=nHARQ+nSR-1N where, nHARQ is the number of information bits of HARQ-ACK or the number of one or more transport blocks received in one or more subframes over two or more configured cells, N denotes a positive integer, and nSR is 1 when the subframe does not have any associated transport block for an uplink shared channel (UL-SCH) and is 0 when the subframe has an associated transport block for the UL-SCH.
