Method and apparatus of receiving data in wireless communication system

摘要

A method and an apparatus of receiving data in a wireless communication system are provided. The method includes detecting a physical downlink control channel (PDCCH) on which control information is transmitted in a first subframe, and receiving data in at least one second subframe based on the control information.

1. A method of receiving, by a user equipment (UE), data in a wireless communication system, the method comprising:
detecting a physical downlink control channel (PDCCH) on which control information is transmitted in a first subframe; and receiving data in a plurality of second subframes in which the PDCCH detected in the first subframe is valid, wherein the receiving of the data is based on the control information, wherein the control information comprises subframe information which indicates a number of the plurality of second subframes that is valid for receiving the data during which the PDCCH detected in the first subframe is valid, wherein a control format indicator (CFI) transmitted on a physical control format indicator channel (PCFICH) in the plurality of second subframes comprises a 32 bit codeword that has a specific value, wherein the specific value is used to determine whether the PDCCH of the first subframe is valid in each of the plurality of second subframes, wherein the subframe information further comprises two offset fields indicating a first offset and a second offset, wherein the first offset indicates an offset in a time domain between the first subframe and a non-adjacent subframe out of the plurality of second subframes, and wherein the second offset indicates an offset in the time domain between two adjacent subframes out of the plurality of second subframes, wherein neither of the two adjacent subframes is the first subframe.
