Method and device for information transmission in wireless communication system

摘要

The present invention relates to a wireless communication system and more specifically relates to a method and device for transmitting information. A wireless communication system can support carrier aggregation (CA). In one aspect of the present invention, a method, in which a terminal transmits information to a base station in a wireless communication system, comprises the steps of: carrying out rate matching for a preset number of symbols in a subframe for transmitting first information on at least one serving cell formed in the terminal; and transmitting the first information from the subframe in which the rate matching has been carried out, to the base station. Therein, the uplink transmission timing of the one or more serving cells are different from one another, and the preset number is determined in accordance with the difference between the uplink transmission timings of the one or more serving cell.

主权项

1. A method for transmitting an uplink signal to a base station by a user equipment in a wireless communication system, the user equipment being configured with a plurality of serving cells, the method comprising:
performing a rate matching for the uplink signal without two single carrier frequency division multiple access (SC-FDMA) symbols within a subframe transmitting the uplink signal, when timing advance values for the plurality of serving cells are different and the subframe transmitting the uplink signal is configured as a subframe for sounding reference signal (SRS) transmission; mapping the rate-matched uplink signal to at least one SC-FDMA symbol except for last two SC-FDMA symbols within the subframe; mapping an SRS to a second to last SC-FDMA symbol within the subframe, when the user equipment is configured to transmit the SRS in the subframe; and transmitting the mapped uplink signal and SRS to the base station in the subframe.
