Title:
MULTIPLE-INPUT AND MULTIPLE-OUPTUT (MIMO) ENHANCEMENT FOR BACKHAUL RELAYS
Document Type and Number:
WIPO Patent Application WO/2013/023093
Kind Code:
A3
Abstract:
Embodiments contemplate one or more methods and apparatuses for allocating demodulation reference signals (DRSs) for a backhaul link between a base station and a relay. One or more embodiments include a processor that may generate a plurality of orthogonal cover codes (OCCs) as a reference for demodulation at a reception end of the backhaul link. The processor may allocate the generated plurality of OCCs in DRS groups to selective resource elements of one or more orthogonal frequency division multiplexed (OFDM) symbols that may be associated with a subframe.
