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 having a first Time Division Duplex Uplink-Downlink (TDD UL-DL) configuration and a secondary cell having a second TDD UL-DL configuration different from the first TDD UL-DL configuration, the method comprising:
receiving, by the wireless device, one or more data within subframe #n−k′ (k′∈K′) on the secondary cell; and transmitting, by the wireless device, acknowledgement information about the one or more data in subframe #n according to a reference TDD UL-DL configuration different from the second TDD UL-DL configuration, 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, wherein TDD UL-DL configurations are defined according to table 2:TABLE 1TDD UL-DLCon-fig-Subframe nuration0  12345  67890— —6—4— —6—41— —7, 64—— —7, 64— 2— —8, 7, 4, 6——— —8, 7, 4, 6——3— —7, 6, 116, 55, 4— ————4— —12, 8, 7, 116, 5, 4, 7—— ————5— —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.
