  • Radio heads and methods and systems for communicating data between radio heads
    Patent number: 7190682
    Abstract: Radio heads, methods and systems are provided for communicating data in a radio communications system. The data communications system includes first and second radio heads. The first radio head has at least first and second transceivers. The first radio head includes a first control processor coupled with each of the at least first and second transceivers wherein the first control processor receives a first plurality of timeslots including at least one control timeslot. The first control processor reads control information from the at least one control timeslot of the first plurality of timeslots and provides the control information from the at least one control timeslot of the first plurality of timeslots to each of the first and second transceivers. Finally, the first control processor generates a second plurality of timeslots. The second radio head includes at least third and fourth transceivers.

  • Method of verifying operation of listening control channel
    Patent number: 7068976
    Abstract: A base station tunes a transceiver to listen to accesses made by mobile terminals on the base station's own control channel. Once the functionality of the transceiver is verified by correlating the known accesses to the received accesses, the base station then tunes the transceiver to control channels of nearby cells to receive accesses directed to those nearby cells. From these accesses, the MSC can determine carrier-to-interference ratios between the cells.
