Method and apparatus for efficient radio unit processing in a communication system

摘要

The method and apparatus of the present invention provides for reduced power consumption and cost while supporting wide bandwidth signals from a large number of antennas, as is required by next generation systems. In accordance with the present invention, a method and apparatus are provided for processing data in a radio unit of a communication system by receiving compressed data at one or more interfaces or internal resources of a distributed switch of a radio unit, operating the distributed switch to match the interface bandwidth to the resource bandwidth and distributing the compressed data received at the one or more interfaces or internal resources to the one or more internal resources or interfaces of the radio unit through the distributed switch.

1. A method for processing data in a radio unit of a communication system, the method comprising:
receiving data at one or more interfaces of a distributed switch of the radio unit, the received data to be transmitted to one or more internal resources of the radio unit, wherein each of the interfaces has an associated interface bandwidth and an associated operating frequency and each of the internal resources has an associated resource bandwidth; operating the one or more interfaces of the distributed switch at the operating frequency associated with the one or more interfaces of the distributed switch if the received data is decompressed data and operating the one or more interfaces of the distributed switch at a reduced operating frequency if the received data is compressed data; operating the one or more interfaces of the distributed switch to match the interface bandwidth of the one or more interfaces to the resource bandwidth of the one or more internal resources; and distributing the received data at the one or more interfaces to the one or more internal resources of the radio unit through the distributed switch at the operating frequency if the received data is decompressed data and distributing the received data at the one or more interfaces to the one or more internal resources of the radio unit through the distributed switch at the reduced operating frequency if the received data is compressed data, wherein the distributing the data received at the one or more internal resources to the one or more internal interfaces of the radio unit through the distributed switch further comprises distributing at least some of the received data to an on-chip memory storage module or an off-chip memory storage module.
