Abstract
Official abstract text for this publication.
A method of a user equipment for performing TDD (Time Division Duplex) operation in a wireless communication system is discussed. The method according to one embodiment includes receiving RRC (radio resource control) signaling indicating whether or not a TDD subframe is being reconfigured; monitoring a PDCCH (Physical Downlink Control Chanel) related with reconfiguring the TDD subframe, if the RRC signaling indicates the TDD subframe is being reconfigured; and performing a TDD operation based on the PDCCH for the reconfiguring the TDD subframe, depending on whether a TDD uplink-downlink configuration indicates the TDD subframe is configured as a special subframe or not.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of a user equipment for performing TDD (Time Division Duplex) operation in a wireless communication system, the method comprising: receiving RRC (radio resource control) signaling indicating whether or not a TDD subframe is being reconfigured; monitoring a PDCCH (Physical Downlink Control Chanel) related with reconfiguring the TDD subframe, if the RRC signaling indicates the TDD subframe is being reconfigured to change from an uplink transmission to a downlink transmission; performing a TDD operation based on the PDCCH for the reconfiguring the TDD subframe, depending on whether a TDD uplink-downlink configuration indicates the TDD subframe is configured as a special subframe or not, wherein the special subframe is indicated, by an indicator related to a reconfigured special subframe, for the downlink transmission, and wherein the indicator is received through a downlink subframe, which exists directly before the special subframe; and transmitting a PUSCH (Physical uplink Shared Channel) corresponding to the PDCCH in another special subframe existing 4 subframes later, if the PDCCH containing an uplink grant for the special subframe is detected. 2. The method of claim 1 , further comprising: performing an uplink transmission by using a GP (guard period) of the TDD subframe, if the TDD uplink-downlink configuration indicates the TDD subframe is configured as the special subframe. 3. The method of claim 1 , further comprising: performing a downlink transmission by using a GP (guard period) of the TDD subframe, if the TDD uplink-downlink configuration indicates the TDD subframe is configured as the special subframe.
