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.

Abstract: PROBLEM TO BE SOLVED: To provide a system for forward link power control that minimizes the overhead required to send power control commands from a mobile station back to a base station. SOLUTION: This invention relates to a method and an apparatus for controlling transmit power levels of a plurality of different data streams (120, 120A, 122, 122A, 124, 124A) transmitted from at least one base station to a mobile station in a mobile radio communication system. The first and second data streams are transmitted from the base station and received at the mobile station. A stream of power control commands is formed at the mobile station in accordance with either the first or second received data stream. A power control signal is formed at the mobile station from the first stream of power control commands and transmitted to the base station. A received stream of power control commands is formed from the received power control signal at the base station, and the transmit power levels of the first and second data streams from the base station are controlled in accordance with the received stream of power control commands.

Abstract: PROBLEM TO BE SOLVED: To puncture symbols in a communication system.
SOLUTION: S symbols are received for a frame having a capacity of N symbols, with S being greater than N. P symbols need to be punctured so that remaining symbols fit into the frame. The number of puncture distances, D1 through DN, are computed based on S and P. A particular number of symbol punctures is determined for each computed puncture distance. P1 through PN symbol punctures are then performed at the distances of D1 through DN, respectively. For a more even distribution of the symbol punctures, each of the distances D1 through DN can be selected to be greater than or equal to a minimum puncture distance Dmin defined as Dmin=[S/P], where []denotes a floor operator.

Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for high rate packet data and low delay data transmissions.SOLUTION: There is provided a method for combination of packet data and low delay data transmissions in a wireless communication system (50). In one embodiment, a parallel signaling channel provides a message to receivers (56, 58, 60) indicating a target recipient of packet data. The message also identifies the transmission channels used for packet data transmissions. Each receiver then selectively decodes only packets where the message identifies the receiver as a target recipient. The data packets stored in a buffer are ignored if the target recipient is another mobile unit. In one embodiment, the message is sent concurrently with the data packet on a parallel channel. In one embodiment, the message is punctured into the high rate packet data transmission.
