    摘要: Embodiments may comprise logic such as hardware and/or code to enable coexistence of high-density and low-density transmissions with a modified CSMA protocol. Embodiments include a self-CTS (self clear to send) packet transmission prior to transmission of a ready to send (RTS) signal when initiating a high density transmission amidst legacy devices. In many embodiments, the self-CTS or the RTS includes a network allocation vector (NAV) having a value for the duration of the transmission. In some embodiments, the self-CTS may include a flag or bit to indicate the Shading Transmission Starts (STS).

    摘要: Device, system, and method of adjusting channel utilization for wireless transmission. For example, a wireless communication unit may control a wireless transmission by a wireless communication device during a contention period, wherein the wireless communication unit is to wait for a back-off period prior to beginning the wireless transmission during the contention period, and wherein a duration of the back-off period is based on a transmission power of the wireless transmission. Other embodiments are described and claimed.

    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.
