Abstract: An code division multiple access (CDMA) communication apparatus (66) in which the apparatus (66) is arranged to receive (14, 56) a signal over a wireless channel, the received signal including a desired signal component and an interference component. The apparatus (66) is arranged to estimate (12) the carrier signal-to-interference and interference energy of the received signal to generate an interference energy value and a signal-to-interference ratio of the received signal, where estimating carrier signal-to-interference and interference energy includes extracting an estimate of the desired signal component from the received signal. The apparatus (66) is further arranged for generating summed weighted-path signals (42) in response to the interference energy value and the estimate of the desired signal component.

Abstract: A method for wireless communication, comprising: receiving data in multiple forward link timeslots; determining a quality metric of the received data; requesting retransmission of the data via a first request scheme if the quality metric indicates the data has not been received correctly; and if retransmission is requested and the data is not received correctly, requesting retransmission of the data via a second request scheme.

Abstract: A method (700) and apparatus for controlling the transmit power allocated to an information signal transmitted from a mobile station is disclosed. A received power control signal value is determined (720) from a power control information signal received at the mobile station. The received power control signal value is compared with a first and second threshold (730, 750). The transmit power of signals sent from the mobile station to a base station on the reverse link is increased if the received power control signal value is greater than the first threshold (740), or decreased if the received power control signal value is less than the second threshold (760).

Abstract: A method and apparatus that determines how much power to allocate to each of a plurality of reverse link power control (RLPC) Channels to be transmitted from a base station, based upon data rate control (DRC) messages transmitted to the base station. Historical information is used to determine the quality of the Forward Link over which the RLPC is to be transmitted. If the history of the DRCs received indicates that the remote station to which the RLPC Channel is to be directed has not transmitted a DRC recently, then the base station allocates power to the RLPC Channels based upon information provided to the base station in DRCs that were received by the base station, but that were directed to other base stations. Accordingly, the base station can allocate power among the RLPC Channels without having received explicit information as to the quality of the Forward Link between the base station and every remote station intended to receive the information on the RLPC Channels.

Abstract: In a high data rate communication system, a method and apparatus for improved throughput while transmitting data packets within multiple time slots. In order to avoid unnecessary retransmissions of a packet, a subscriber station sends a Stop-Repeat signal to a base station, causing the base station to cease further transmissions of the packet. In order to enable successful decoding of a packet, a subscriber station sends a Continue-Repeat signal to a base station, causing the base station to send retransmissions of the packet during time slots beyond a predetermined default number of time slots.
