Abstract: A method for communicating DM-RS symbols to support MIMO transmissions having five or more layers of spatial multiplexing. A first subframe is communicated carrying two leading symbols of a first length-4 OCC sequence and two leading symbols of a second length-4 OCC sequence, and a second subframe is communicated carrying two trailing symbols of the first length-4 OCC and two trailing symbols of the second length-4 OCC sequence. Optionally four length-2 OCCs can be carried in a similar manner or, alternatively, in different frequency bands or resource block pairs of a common subframe.

Abstract: A method for wireless communication comprises a donor enhanced Node B (eNB) transmitting system information for a subframe structure to a relay node (RN), which information comprises radio resource configuration and/or timing information for uplink backhaul transmission. The RN uses an automatic method to select the Round Trip Time (RTT) value for the Hybrid Automatic Repeat request (HARQ) on the uplink backhaul (Un) relay link. The RTT value is implicitly determined according to the Un (backhaul) subframe or MBSFN subframe configuration periodicity. The RTT option is signaled by the Un subframe configuration period of the MBSFN Un downlink signals.
