DATA TRANSMISSION METHOD AND DEVICE IN WIRELESS COMMUNICATION SYSTEM

摘要

A method, and a user equipment (UE), for transmitting control information. The method according to one embodiment includes receiving a sounding reference signal (SRS) simultaneous transmission parameter; and if the SRS simultaneous transmission parameter is true, transmitting an SRS, and, in cell specific SRS subframes of a primary component carrier, a physical uplink control channel (PUCCH) which coincides in a same subframe as the SRS. The PUCCH using a shortened format carries at least one of a HARQ-ACK and a positive scheduling request (SR). The method according to the embodiment further includes, if the SRS simultaneous transmission parameter is false, transmitting the PUCCH which uses a normal PUCCH format and carries at least one of the HARQ-ACK and the positive SR, while not transmitting, in a secondary component carrier, the SRS which coincides in the same subframe. The transmitting of the PUCCH uses carrier aggregation.

1. A method of transmitting control information by a user equipment (UE) in a wireless communication network, the method comprising:
receiving, by the UE via a higher layer, a sounding reference signal (SRS) simultaneous transmission parameter; if the SRS simultaneous transmission parameter is true, transmitting, by the UE, an SRS, and, in cell specific SRS subframes of a primary component carrier, a physical uplink control channel (PUCCH) which coincides in a same subframe as the SRS, wherein the PUCCH using a shortened format carries at least one of a HARQ-ACK and a positive scheduling request (SR); and if the SRS simultaneous transmission parameter is false, transmitting, by the UE, the PUCCH which uses a normal PUCCH format and carries at least one of the HARQ-ACK and the positive SR, while not transmitting, in a secondary component carrier, the SRS which coincides in the same subframe as the PUCCH carrying at least one of the HARQ-ACK and the positive SR, wherein the transmitting of the PUCCH uses carrier aggregation to transmit the PUCCH via two or more of a plurality of component carriers (CCs) simultaneously, and one or more CCs of the plurality of CCs are assigned to the UE according to a CC capacity.
