Abstract:
1. A method, comprising: receiving a first plurality of resource blocks, frequency multiplexed in a transmission subframe, wherein the first plurality of resource blocks spans less than a full transmission bandwidth, wherein the first plurality of resource blocks comprises a user equipment (UE) control channel in a first time interval spanning three OFDM symbols, a relay control channel and a first plurality of dedicated reference symbols in a second time interval following the first time interval and spanning four OFDM symbols, and a shared data channel and a second plurality of dedicated reference symbols in a third time interval, and wherein the first plurality of resource blocks lacks a shared data channel in the second time interval; decoding relay control information from the relay control channel; decoding relay data and user data from the shared data channel; and receiving a second plurality of resource blocks in the transmission subframe, the second plurality of resource blocks frequency multiplexed with the first plurality of resource blocks and comprising a shared data channel in the second and third time intervals, wherein at least two of the first plurality of dedicated reference symbols in the second time interval are mapped to time-adjacent symbols, and at least two of the second plurality of dedicated reference symbols in the third time interval are mapped to time-adjacent symbols.
