SYNCHRONIZATION OF TRANSMITTER AND RECEIVER FREQUENCIES IN MULTIACCESS NETWORKS

摘要

The present invention provides methods and apparatus for integrating the operation of a plurality of radio networks. The plurality of radio networks may utilize a common frequency spectrum. The radio center frequencies are adjusted so that frequency drift in relation to each radio network is reduced. Also, system information about the plurality of radio networks may be sent on a radio channel that is associated with one of the radio networks. An oscillator synchronizer synchronizes a first reference oscillator that is associated with a first radio network and a second reference oscillator that is associated with a second radio network in order to adjust radio center frequencies. With a variation of the embodiment, a reference oscillator of one of the radio network adjusts center frequencies for radios that are associated with the other radio network.
