Abstract: A system and method for performing topology control in a wireless network (100). The system and method operate to enable a node (102-1) to determine the link cost of a link between itself and another node (102-2), based on the number of nodes (102, 106, 107) that would be affected by message transmission by the node (102) and the other node (102-2), and the number of nodes (102, 106, 107) that would be affected by message reception by the node (102-1) and the other node (102-2). The number of nodes (102, 106, 107) affected by the message transmission and message reception at the node (102-1) and the other node (102-2) is affected by the transmit power of the control messages sent by the node (102-1) and the other node (102-2). The node (102-1) further bases routing decisions on the calculated link costs.

Abstract: A method of reverse link power control for a reverse packet data channel in a wireless communication system allows a mobile station to autonomously change its data transmission rate. The mobile station transmits packet data over a reverse packet data channel having a data rate variant transmit power level that varies based on a transmit data rate on the packet data channel. The mobile station further transmits control signals over a reverse control channel associated with the reverse packet data channel. The transmit power level of the reverse control channel is such that the transmit power level does not vary with the transmit data rate on the packet data channel. The radio base station measures the strength of the received signals on the reverse control channel, compares the measured strength to a power control set point, and generates a power control signal responsive to the comparison of the control signal to the power control set point.

Abstract: A system and method for dynamically optimizing the performance of indoor distributed antenna systems communicate to user equipment is disclosed. The user equipment measures information describing the downlink signals such as the downlink data rates, the quality of the received signal, and the location of the user equipment. A service module collects this information and determines an optimized power level for each of the antenna units. The service module may optimize only one antenna unit power level or a subset of the antenna units within the distributed antenna system in a preferred embodiment. One or more of the antenna units then transmits downlink signals with the optimized power levels. The optimized power level may be less than the initial power level in a preferred embodiment. As a result, the performance of the indoor distributed antenna systems is enhanced.

Abstract: Methods and apparatus for scheduling mobile stations (MSs) to download data to and/or to control the rate of downloading to an MS from a base station (BS) as a function of downlink channel condition information are described. Artificial channel variations, which can be measured at the MS, and feedback to a BS for scheduling purposes, are introduced through the use of two or more transmitter antennas at a BS. Each of the antennas transmits a signal at the same frequency having the same information content, e.g., modulated data. However the signals are made to differ with time in their phase and/or amplitude. Multiple signals having the same transmission frequency and information content are received and interpreted as a single composite signal by a receiving MS.

Abstract: In a method of selecting a transport format combination according to the present invention, a mobile station calculates the transmission power of a first physical channel using a first TFC with respect to each of first TFCs, and determines whether the mobile station is in a transmission capable state or not. Then, the mobile station calculates the sum of the transmission power of first and second physical channels using first and TFCs, with respect to each of combinations of the first and second TFCs, and determines whether the mobile station is in the transmission capable state or not. Then, the mobile station selects a first TFC from the first TFCs wherein the mobile station is in the transmission capable state. Then, the mobile station selects a second TFC from the second TFCs which are included in combinations wherein the mobile station is in the transmission capable state among the combinations including the selected first TFC. Thereafter, the mobile station transmits data in the first and second physical channels using the selected first and second TFCs, respectively.

Abstract: In a compressed mode, a spread spectrum communication device interleaves bit units across multiple frames using an interleaver, reduces the spreading factor using a framing/spreading unit, outputs the compressed mode frames at a predetermined compressed mode frame timing, and increases the average transmission power in the compressed mode at a radio frequency transmitter. Furthermore, a handover between different frequencies is carried out by establishing synchronization to another frequency carrier, based on a first search code and a second search code which have been detected, and moreover, a handover between different communication systems is carried out by establishing synchronization to a GSM, based on an FCCH and a SCH which have been detected.
