Abstract
An Advanced Antenna System (AAS) receiver and related methods are provided. According to one aspect an AAS receiver comprises a digital processing block of a Radio Frequency Integrated Circuit (RFIC). The digital processing block comprises an interface for communicating with a Central Unit (CU), and a plurality of Antenna Signal Processing Blocks (ASPBs), each receiving a digitized receive signal from a respective antenna element of an antenna array. Each ASPB comprises one or more receivers, each of which receives and processes the signal from the respective antenna element. Some receivers within the ASPB beamform the respective processed signal to produce one or more data streams to be sent to the CU. Other receivers within the ASPB provide the respective processed signal to a processing block that buffers the processed signal and sends it to the CU at a later time, e.g., when traffic to the CU is relatively lower.
