Abstract
This letter investigates self-backhauling with dual antenna selection at multiple small cell base stations. Both half-duplex (HD) and full-duplex (FD) transmissions at the small cell base station are considered. Depending on instantaneous channel conditions, the FD transmission can have higher throughput than the HD transmission, but it is not always the case. Closed-form expressions of the average throughput are obtained and validated by the simulation results. In all cases, the dual receive and transmit antenna selection significantly improves backhaul and data transmission, making it an attractive solution in practical systems.
