    摘要： An embodiment of the present invention provides an apparatus, comprising a subscriber station (SS) operable to communicate with a base station (BS) and at least one additional subscriber station (SS) in a wireless metropolitan area network, wherein the at least one additional SS attempts to overhear a first message from the SS and piggy back a second message for the overheard message from the SS's uplink data to the BS with its uplink data.

    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： Retransmission techniques are disclosed. These techniques may be used in networks employing contention-based access schemes, such as CSMA. For instance, a device may receive a corrupted packet from a transmitting device, and determine a cause of the corruption. When the determined cause of the corruption is an in-network packet collision, the device allows the transmitting device to send a retransmission of the packet in accordance with a contention-based access scheme. However, when the determined cause of the corruption is other than an in-network packet collision, the device provides retransmission assistance to the transmitting device. This retransmission assistance may include a channel reservation for a retransmission, and/or one or more link adaptation suggestions for the transmitting device.

    摘要： Embodiments of a wireless device and method for channel access are generally described herein. In some embodiments, the wireless device is configured to measure channel quality and set a backoff delay for channel access based on the channel quality. Shorter backoff delays are set for better channel quality and longer backoff delays are set for poorer channel quality.
