Mobile telecommunications network with distributed base stations

摘要

A mobile telecommunications local area network (20) is described with a concentrator (32) connected to a plurality of radio heads (36, 38) via a local area network (LAN, 20). The concentrator (32) provides remote control of a local timing signal individually in each radio head. The control may be open loop or closed loop and may be provided through the LAN. The concentrator may also provide digital signal processing (DSP) as a shared resource for the radio heads (36, 38). The DSP may include channel coding. The radio heads (36, 38) may provide modulation for channel coded signals transmitted from the concentrator (32) via the LAN (20). The LAN may be wired LAN or a wireless LAN.

主权项

1. A concentrator for connection on one side to a mobile radio communication network, and for connection on another side on a local area network (LAN) having at least one radio head, the concentrator comprising:
at least one interface to the LAN for receiving incoming radio samples and transmitting outgoing radio signals; and digital signal processing units for:
processing at least user messages and/or signaling messages to generate the outgoing radio signals,transmitting the outgoing radio signals to the at least one interface for transmission from a radio transmitter,performing at least one function, said at least one function comprises channel coding of the user messages and/or signaling messages to generate outgoing channel coded radio signals, andremotely controlling a local timing signal required for operation of the at least one radio head on the LAN, wherein a number of the at least one interface is less than a number of the at least one radio head.
