METHOD FOR TRANSMITTING UPLINK CONTROL INFORMATION, USER EQUIPMENT, METHOD FOR RECEIVING UPLINK CONTROL INFORMATION, AND BASE STATION

摘要

In the present invention, a physical uplink control channel (PUCCH) resource, which is used for transmitting acknowledgement/negative ACK (ACK/NACK) information related to downlink control information, is determined on the basis of n(1)PUCCH=f(nCCE,N(1)PUCCH,X), when the format of the downlink control information that is transmitted/received through a physical downlink control channel (PDCCH) is in accordance with a transmission mode of a user equipment, wherein n(1)PUCCH is a PUCCH resource index, N(1)PUCCH is a value which is received from the base station, nCCE is a first control channel element (CCE) index in the PDCCH, X is a parameter which is not the nCCE and the N(1)PUCCH, and wherein ƒ is a function having the nCCE, N(1)PUCCH, and the X as a factor.

1. A method for transmitting an uplink signal to a base station by a user equipment in a wireless communication system, the method comprising:
receiving downlink control information from the base station through a physical downlink control channel (PDCCH); and transmitting acknowledgement/negative acknowledgement (ACK/NACK) information associated with the downlink control information to the base station, wherein, when a format of the downlink control information is a first format according to a transmission mode of the user equipment, the ACK/NACK information is transmitted using a physical uplink control channel (PUCCH) resource determined based on Equation 1,
n(1)PUCCH=ƒ(nCCE,N(1)PUCCH,X)  [Equation 1]  where n(1)PUCCH is a PUCCH resource index, N(1)PUCCH is a value received from the base station, nCCE is an index of a first control channel element (CCE) in the PDCCH, X is a parameter other than nCCE and N(1)PUCCH, and ƒ is a function having nCCE, N(1)PUCCH, and X as arguments.
