Claim Text:
1. A method of receiving signals, the method comprising: receiving, by a wireless station from a base station, a first signal, wherein the wireless station and the base station are configured to use at least one of a plurality of time division duplex (TDD) uplink-downlink (UL-DL) subframe configurations, each of which indicates locations of one or more TDD DL subframes and one or more TDD UL subframes in a radio frame, wherein the radio frame comprises 10 subframes, wherein the first signal includes first information indicating that at least one TDD UL subframe indicated by the at least one of the plurality of TDD UL-DL subframe configurations is reconfigured as at least one TDD DL subframe, and wherein the at least one of the plurality of TDD UL-DL subframe configurations corresponds to one or more of configurations in Table 1 below, wherein ‘D’ denotes a DL subframe, ‘U’ denotes a UL subframe, and ‘S’ denotes a special subframe: receiving, by the wireless station from the base station, DL data on a subframe which was indicated as a TDD UL subframe by the at least one TDD UL-DL subframe configuration but is currently reconfigured as the TDD DL subframe by the first signal, wherein the subframe, which was indicated as the TDD UL subframe by the at least one of the plurality of TDD UL-DL subframe configurations, but is currently reconfigured as the at least one TDD DL subframe, is not allowed for other wireless devices to perform a transmission; and transmitting, by the wireless station to the base station, UL data on a TDD UL subframe except for being reconfigured as the TDD DL subframe by the first signal.
