Method for transmitting/receiving signal and device therefor

摘要

The present invention relates to a wireless communication system. More particularly, the present invention relates to a method comprising: setting a first cell having a first TDD UL-DL configuration and a second cell having a second TDD UL-DL configuration; receiving a PHICH signal in a subframe #(n−L) of the first cell, or receiving a PDCCH signal in a subframe #(n−K) of the first cell; and transmitting a PUSCH signal in a subframe #n of the second cell, corresponding to the PHICH signal or the PDCCH signal, wherein the relationship between the subframes #(n−L), #(n−K), and #n is determined in consideration of a parameter value set in a specific TDD UL-DL configuration, which is the TDD UL-DL configuration having the least number of UL subframes from TDD UL-DL configuration(s), in which subframes set as UL in the first or second cell are all set as ULs.

1. A method for transmitting an uplink signal by a device in a wireless communication system supporting carrier aggregation, the method comprising:
configuring, by the device, a secondary cell having a second Time Division Duplex Uplink-Downlink (TDD UL-DL) configuration and a primary cell different from the secondary cell and having a first TDD UL-DL configuration different from the second TDD UL-DL configuration; receiving, by the device, data within subframe #n−k′ (k′εK′) of the secondary cell; and transmitting, by the device, acknowledgement information about the data in subframe #n of the primary cell according to a reference TDD UL-DL configuration, the reference TDD UL-DL configuration being one of the first TDD UL-DL configuration or another TDD UL-DL configuration different from the first and second TDD UL-DL configurations, wherein K′ consists of a subset of elements of K: {k0, k1, . . . , kM-1} of the reference TDD UL-DL configuration as defined in Table 1 below such that subframe #n−k in the secondary cell is only a downlink subframe or a special subframe:TABLE 1TDD UL-DL Config-Subframe nuration01234567890——6—4——6—41——7, 64———7, 64—2——8, 7, 4, 6————8, 7, ——4, 63——7, 6, 116, 55, 4—————4——12, 8, 6, 5, ——————7, 114, 75——13, 12, 9, ———————8, 7, 5, 4, 11, 66——775——77—.
