Abstract:
Apparatuses, methods, and systems for selecting an ADC for each RF chain of an RRU are disclosed. One embodiment of the RRU includes a plurality of antennas and a plurality of RF chains configured to receive a plurality of wireless signals, A plurality of outputs of the RRU connected to a front-haul, wherein the front-haul electrically connects the plurality of outputs of the RRU to a baseband unit (BBU), wherein each of the outputs is connected to an output of one of a plurality of ADCs. Further, the RRU selects a one of the plurality of ADCs having the plurality of ADC resolutions for each of the RF chains based on the capacity of the front-haul, a channel gain of each of the RF chains, and a performance parameter of the RRU. A switch connects each of the RF chains to a corresponding one of the plurality of ADCs.
