Radio system having distributed real-time processing
First Claim
1. A distributed radio system for communication between a wireless user equipment and a network comprising:
- a radio unit configured to;
transmit outgoing signals to the user equipment;
receive incoming signals from the user equipment; and
perform radio-level processing on data associated with received and outgoing signals;
an intermediate-level processing unit connected to the radio unit and configured to perform intermediate-level processing on data associated with received and outgoing signals; and
a network-level processing unit connected to the intermediate-level processing unit via a local network and configured to perform network-level processing on data associated with received and outgoing signals;
wherein the network-level processing unit is configured to provide to the wireless user equipment, via the radio unit and the intermediate-level processing unit, access to one or more external telecommunications networks.

Abstract
A distributed radio system is disclosed. Transmit and receive packets of data are transported over a relatively high-speed multiplexed network, which in one embodiment may be an Ethernet network. The distributed radio system comprises in one embodiment a centrally-located network-level processing unit connected via network connections to one or more intermediate-level processing units. The intermediate-level processing units may be distributed throughout the coverage area. The processing units perform digital signal processing, as well as higher level processing such as signal routing, speech transcoding and proper interfacing to external environments, such as a macrocellular environment. Radio elements are provided that are accurately timed or synchronized, such that the radio elements have their own time base to ensure proper transmission, even when unpredictable network delays occur.
