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 wireless device configured with a primary cell of a first Time Division Duplex Uplink-Downlink (TDD UL-DL) configuration and a secondary cell of a second TDD UL-DL configuration different from the first TDD UL-DL configuration in a wireless communication system, the method comprising:
for one or more downlink data on the secondary cell in subframe #n−k′ (k′εK′), generating, by the wireless device, acknowledgement information about the one or more downlink data; and transmitting the acknowledgement information in subframe #n, wherein K′ contains elements of K:{k0, k1, . . . kM-1} of the reference TDD UL-DL configuration such that subframe #n−k′ is a downlink subframe or a special subframe for the secondary cell, and the reference TDD UL-DL configuration is given as:
TDD UL-DL configuration #4 when (the first TDD UL-DL configuration, the second TDD UL-DL configuration) corresponds to (#1, #3) or (#3, #1), andTDD UL-DL configuration #5 when (the first TDD UL-DL configuration, the second TDD UL-DL configuration) corresponds to (#2, #3), (#3, #2), (#2, #4) or (#4, #2), wherein K:{k0, k1, . . . kM-1} is defined in Table 1, and TDD UL-DL configurations are defined according to table 2:TABLE 1TDD UL-DLSubframe nConfiguration01234567890——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—TABLE 2Uplink-downlinkSubframe numberconfiguration01234567890DSUUUDSUUU1DSUUDDSUUD2DSUDDDSUDD3DSUUUDDDDD4DSUUDDDDDD5DSUDDDDDDD6DSUUUDSUUD wherein D denotes a DL subframe, S denotes a special subframe and U denotes an UL subframe.
