    摘要： An apparatus and method for HARQ timing control in wireless communication systems is disclosed. The apparatus and method provides one unified algorithm to determine HARQ timing, with consideration of the downlink-to-uplink ratio, the presence of legacy zones, support of relay zones, and variable transmission time interval length. The disclosed algorithm guarantees sufficient processing time, at both the transmit and receive sides. Further, retransmissions occur in a periodic manner, simplifying the implementation.

    摘要： Embodiments of a base station and methods for allocating uplink bandwidth using SDMA are generally described herein. In some embodiments, uplink bandwidth request messages are received on a bandwidth request contention channel from one or more subscriber stations. The uplink bandwidth request messages are generated by the subscriber stations by modulating pilot subcarriers of a randomly selected disjoint pilot pattern with a randomly selected orthogonal sequence. The base station allocates uplink bandwidth to the subscriber stations when the uplink bandwidth request messages are successfully detected and decoded. The base station uses an SDMA technique to determine channel responses based on the orthogonal sequences to detect and decode the uplink bandwidth request messages.

    摘要： Embodiments provide techniques for power control. For instance, a method exchanges one or more transmissions with a remote device in accordance with a retransmission protocol. In addition, a power control message is exchanged with the remote device through at least one of the one or more transmissions. Thus, closed loop power control may be performed through retransmission protocol communications.

    摘要： Methods and apparatuses for scheduling transmissions between a base station and multiple user stations in a broadband wireless access network may include a subscriber station generating a bandwidth request which includes one of a limited number of available and predefined preamble sequences and a data portion identifying the resources requested. The subscriber station randomly selects a contention slot in a wireless channel, allocated by the base station, for sending a bandwidth request. The receiving base station is able to detect the preamble sequence of bandwidth requests and differentiate between subscribers even when bandwidth requests of two or more subscribers may collide by virtue of selecting the same contention slot. In this manner, latency and overhead of bandwidth requests may be improved. Additional variants and embodiments are also disclosed.
