Precoding and feedback schemes for a MIMO backhaul link in the presence of interference
The focus of this paper is on the precoding and feedback strategies for a radio backhaul link between an access base station (ABS) and the hub base station (HBS) in the presence of mobile stations (MS's) that communicate with the ABS producing interference over the HBS. In this paper it is assumed that the access and the backhaul links are simultaneous and use the same frequency band. Two feedback links are exploited at the ABS in order to optimize the communication through the radio-backhaul link: the MS's feed back the channel state information (CSI) of the channels between the ABS and the MS's, and the HBS feeds back the statistics of the received interference. Using this information, the transmission strategy at the ABS can be designed in order to transmit to the HBS without interfering with the MS and at the same time minimizing the effect of the interferences received at the HBS.
