Abstract: A method for increasing cellular system capacity includes receiving a signal in a time slot and a frequency band and transmitting a signal in the same time slot and the same frequency band. An adaptive self-interference canceller is used to reduce the radio frequency self-interference created by receiving and transmitting signals in the same time slot and the same frequency band. The self-interference can be further reduced by using: (1) a circulator connected between an antenna, a receiver, and a transmitter; (2) separate antennas for receiving and transmitting signals can be used; and/or (3) an adaptive antenna.

Abstract: A simulation is used to determine the effect of additional users on a communications system, such as a slotted wireless communications system. Users are sequentially added and determinations are made as to whether criteria for the additional user fall within predetermined limits. If the criteria are met, the user is accepted by the simulation and a power balancing is performed for all users. The simulation is repeated for each additional user. If the parameters are not within predetermined limits, the user is dropped. The simulation presents the system in a series of nullsnapshotsnull of communications activity.

Abstract: A method and system for positioning mobile units using angle measurements taken by neighboring mobile units is disclosed. A selected mobile unit and mobile units in the vicinity of the selected mobile unit are selectively instructed to measure and report information related to the position of the selected mobile unit. The reported information is used to compute a position of the selected mobile unit.

Abstract: A UE transmitter in a 3G UTRAN wireless communication system performs dynamic link adaptation (DLA) with dynamic semi-static parameters for overcoming RF propagation difficulties. Separate transport channels (DCH) are defined for each semi-static parameter, including forward error coding (FEC) coding type and rate. When data rate is decreased during DIA, a TFC is selected having the desired FEC coding type and rate. Since this adjustment occurs at each TTI, mapping of data packet codes in each timeslot on the physical channel includes the benefit of FEC rather than reduced data rate alone. This permits improved SIR in a timeslot that may be experiencing RF propagation difficulties during the UL mapping process.
