Abstract: PROBLEM TO BE SOLVED: To provide a technique for improved margin control in a data communication system. SOLUTION: In one aspect, a margin is adjusted in response to a first subpacket error rate (715) to (735). In another aspect, the margin is further adjusted in response to an overall packet error rate. In yet another aspect, the first subpacket error rate is adjusted in response to an overall packet error rate. These aspects have the benefit of responsive margin control when the overall packet error rate is relatively low, resulting in improved data throughput and increased system capacity.

Abstract: PROBLEM TO BE SOLVED: To provide a new and improved method for decreasing a peak-to-average ratio in a system using an auxiliary pilot channel. SOLUTION: A system using the auxiliary pilot channel is described in TIA/EIA for ITU, cdma 2000 for TR45.5 ITU, and ITU-R RTT Candidate Submission for discussion in the third-generation wireless communication system. The first method is to change a phase in the auxiliary pilot channel. Consequently, the auxiliary pilot channel can be prevented from accumulative application. The second method is to gate out part of the modified auxiliary pilot channel to be applied in an accumulative manner. Further, a signal is decoded by means of the modified auxiliary pilot channel.

Abstract: PROBLEM TO BE SOLVED: To provide a time offset technique for increasing the capacity of a CDMA system.
SOLUTION: In a method for limiting a peak transmission power region in a CDMA communication system by transmitting a first communication signal having a first high transmission power region and transmitting a second communication signal having a second high transmission power region, the first and second communication signals are time offset to prevent the first and second high transmission power regions from occurring simultaneously. Time shifting of only a portion of the first and second communication signals is also taught. The first and second communication signals can also include respective first and second low transmission power regions. The time offset can be selected to align one of the first and second high transmission power regions with one of the first and second low transmission power regions. The total transmission power signal can be determined and the time offset can be selected to minimize the peak level of the total transmission power signal.

Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for controlling transmission power of a base station in soft handoff.
SOLUTION: Transmitters 20, 32 are attached to a separated control unit 12 through communication links. The control unit 12 then derives the most likely command stream to be sent to a base station. In a second exemplary embodiment, the control unit periodically receives the final or average transmission level in a period and an aggregate quality measure for the feedback during a period from each of the transmitters. The control unit 12 determines the aligned power level and transmits a message indicative of the aligned power level to the transmitters. In a third exemplary embodiment, the transmitters 20, 32 send a message indicative of the transmission power of transmission to the receiver. The control unit 12 determines the aligned transmit power, based on the current transmission power.
