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 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： Briefly, in accordance with one or more embodiments, in a HARQ supported client relaying wireless network, if the intended client subscriber station is able to decode the transmission from the base station, an allocated data zone otherwise allocated for relay transmission and acknowledgment zones in the uplink subframe can be used by another client station for uplink transmission. If the intended client subscriber station cannot decode the transmission from the base station but the relay station can, the relay station may use the allocated data zone in the uplink subframe in which to transmit a relay transmission, along with acknowledgment transmissions in the acknowledgment zones. If the relay station also cannot decode the base station transmission, the other client station may use the allocated data otherwise allocated for relay transmission and acknowledgment zones for uplink transmission.
