    Abstract: Various embodiments are described to address the need for an apparatus and method of outer-loop power control for enhanced uplink communications that address some of the outstanding problems in the prior art. Generally expressed, a base site (131), while a first uplink channel is inactive, monitors packet retransmissions to generate an uplink quality indicator. Here, packet retransmissions refers to the number of packet retransmissions used by a remote unit (101) to send packets to a base transceiver station (111) via at least one other uplink channel. Also, while the first uplink channel is inactive, the base site adjusts a signal-to-interference ratio (SIR) target for the first uplink channel based on the uplink quality indicator. Then, when the first uplink channel becomes active, the base site begins power controlling the first uplink channel using the SIR target.

    Abstract: The present invention provides a method of scheduling asynchronous transmissions for a plurality of subscriber units (12). The method includes receiving (305) information associated with a plurality of subscriber units that have uplink data to transmit, the information including uplink timing offset information associated with each of the subscriber units (12). Two or more subscriber units (12) are then selected (310) from a set of subscriber units having a timing offset differential, that is below a predetermined threshold, where the timing offset differential is the difference between the timing offset of a first subscriber unit and the timing offset of a second subscriber unit further selectively offset by a multiple of the transmission segment size, which minimizes the difference. The transmission segments, which are available for the uplink of data, are then allocated (315) between the selected two or more subscriber units (12), which limits the number of transmission segments that have at least one of an overlap or a gap, and the amount of any overlap or gap, in order to minimize wasted scheduling opportunities.

    Abstract: Embodiments described herein address the desire to have a method for uplink rate control signaling that is able to achieve increased sector and user throughput with relatively high uplink spectrum efficiency. Rate control signaling embodiments are disclosed that use two common persistence values (404, 408) to update the allocated portion of RoT margin for each UE device, and thus, reduce the variation of the RoT. In addition, SHO information is used to control the inter-sector/cell interference and improve the sector throughput. In such embodiments, each UE determines (412) the data rate and time to transmit according to these common persistence values, SHO status and buffered data. Throughput comparable to that of time and rate schedulers, which require significantly more signaling and information, can be achieved by some of these embodiments while also exhibiting less sensitivity to delay, speed of the UE, and burstiness of the traffic.
