    摘要: A method for interference cancellation in a device that receives transmissions from multiple sources is disclosed. The method includes receiving multiple slots, each including a pilot segment and a traffic segment. A first one of the slots includes information indicating an activity level of a traffic segment of the first one of the slots. The method also includes calculating a value associated with interference among the plurality of slots, utilizing the information indicating the activity level to account for an amount of interference attributable to the first one of the slots. Furthermore, channel conditions are estimated for a second one of the slots using the value associated with the amount of interference. The method also includes processing the second one of the slots according to the estimated channel conditions.

    摘要: Techniques for supporting broadcast/multiple transmission to multiple terminals with feedback and rate adaptation are described. In an aspect, a combination of HARQ and at least one shared feedback channel may be used to support broadcast/multicast transmission. In one design, a base station may send at least one transmission of a packet to multiple terminals, one transmission at a time. The base station may receive feedback information (e.g., NAK) for the packet from the terminals on the shared feedback channel(s). The base station may determine whether to terminate the packet early and/or may select at least one transmission parameter for another packet based on the feedback information for the packet. In another aspect, a transport format for a broadcast/multicast transmission may be selected based on CQI information from terminals receiving the transmission. The terminals may send CQI information at a slow rate and/or only certain terminals may send CQI information.

    摘要: Broadly speaking, the invention comprises systems and methods that use the number of mobile stations, denoted by N, communicating with a base station, as a variable that determines the optimum induced change rate, R, and the antenna beam width, W, of a time-varying base station antenna gain pattern used in conjunction with a forward power modulation (FPM) or a similar scheme to maximize the overall data throughput from the base station by taking advantage of multi-user diversity. In one embodiment, the FPM scheme is turned off if N is below a lower threshold. If N is above this threshold, the FPM scheme is turned on with R and W set to appropriate values. Generally, higher values of N correspond to higher values of R and lower values of W.

    摘要: A system (100) and various methods and apparatus for efficient communications of data across various protocol layers are disclosed. A control and transceiver system (1400) configured for determining a data rate control (DRC) value and for transmission a maximum number of time slots allowed for transmission of a physical layer packet of data (510). After detecting a normal termination of transmission, the decoding thresholds (401, 402) are adjusted for decoding a positive acknowledgment message, and repeating decoding of acknowledgment channel (340) with the adjusted thresholds (401, 402). Retransmitting the physical layer packet of data at least one more time after based on whether the repeat of decoding of the acknowledgment channel (340) produces a negative acknowledgment message. The retransmission may be conditioned upon a throughput level of communications between the base station and the mobile station.

    摘要: Adaptive delay management means and method for allocating resources having different Quality of Service (QoS) requirements. A Forward Link (FL) scheduler prepares transmission instances by treating pending data queues according to a priority class, such as Best Effort (BE) and Expedited Forwarding (EF). Data bits from multiple queues are stuffed into a transmission instance. Various metrics are used to generate a set of candidates for transmission and then select and build a next transmission instance from the set of candidates.
