    Abstract: A method for transmitting data within a communication system (100) comprises determining a carrier bandwidth from a set of two or more carrier bandwidths, receiving data to be transmitted over a radio frame (300, 400, 500), wherein the radio frame is comprised of a plurality of subframes (301, 401, 501), and placing data within a subframe in the radio frame to produce a subframe of data. The subframe of data comprises either a plurality of OFDM symbols or a plurality of single carrier FDMA symbols, at least two of the OFDM symbols or at least two of the single carrier FDMA symbols in the subframe having different symbol durations. The radio frame and subframe have the same duration for each of the carrier bandwidths in the set of two or more carrier bandwidths. The OFDM symbols or single carrier FDMA symbols in the subframe comprise a plurality of subcarriers and wherein the plurality of symbols and subcarriers in the subframe are grouped into resource blocks such that the carrier bandwidth is divided into an integer number of resource blocks. The at least two OFDM or single carrier FDMA symbols in each of the plurality of subframes differ in cyclic prefix duration by one sample duration corresponding to the smallest carrier bandwidth in the set of two or more carrier bandwidths. The subframe of data is transmitted over the radio frame and in the determined carrier bandwidth. A mobile station or a base station adapted to perform the steps of the method for transmitting data is also disclosed and claimed.

    Abstract: A method to provide a nominal best effort data rate based on a Quality of Service (QoS) requirement of a user data connection, the method comprising assigning ( 105 ) a service priority based on the QoS requirement, and assigning ( 110 ) the nominal best effort data rate for the service priority using a predetermined function. Further, it comprises of a method to determine a scheduling priority value for a user data connection by providing a relative fairness. Furthermore, the method comprises a method to satisfy a delay requirement for a delay sensitive data connection through a scheduling.

    Abstract: To address the need for a resource allocation scheme that results in a bette r tradeoff between cell-edge performance and overall spectral efficiency, a communication system (100) is provided that allocates uplink transmit power to user equipment (UEs) (102, 104) based on a fractional power control scheme (300). In another embodiment, since the cell-edge users are also likely to be power limited, the communication system may implement a minimized uplink transmission bandwidth resource allocation scheme (404, 406, 408, 410, 412, 414) that may work with the fractional power control scheme to achieve a level of performance desired fo r uplink transmissions in 3GPP (Third Generation Partnership Project) and 3GPP2 Evolution communication systems.

    Abstract: A method of combining soft-handoff with a hybrid ARQ scheme to maximize throughput and gain in a communications system. After receiving a frame from the MS (110), the BTSs (104 and 106) will process the frame and communicate to the MS over a forward control channel whether the frame contained any errors. If all BTSs communicate that the frame contains errors, the MS will retransmit the same frame to all BTSs with a flush bit set to instruct the BTSs 104 and 106 to combine the retransmitted frame with the original frame. If only some BTSs communicate that the frame contains errors, the MS will transmit the next frame to all BTSs that successfully decoded the frame with the flush bit set to instruct the BTSs to erase the previous frame from memory and not to combine the previous frame with the current frame. The MS will retransmit the frame to the BTSs that did not successfully decode the frame with the flush bit set to instruct the BTSs to combine the previous frame with the retransmitted frame.

    Abstract: A method for rate selection by a communication device for enhanced uplink during soft handoff in a wireless communication system includes a first step of receiving information from a scheduler. This information can include one or more of scheduling, a rate limit, a power margin limit, and a persistence. A next step includes determining a data rate for an enhanced uplink during soft handoff using the information. A next step includes transmitting to a serving base station on an enhanced uplink channel at the data rate determined from the determining step.
