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:
Embodiments may comprise logic to determine whether a value of a network allocation vector indicates that the apparatus is blocked from transmitting on the medium; logic to transmit a first clear to send packet at a first power level in response to determining that the apparatus is not blocked from transmitting on the medium, the first clear to send packet comprising a flag or bit to indicate the Shading Transmission Starts (STS); logic to receive a second clear to send packet after transmitting the first clear to send packet; and logic to transmit a first data transmission at a second power level after receiving the second clear to send packet, the second power level being less than the first power level.

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.

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.

Disclosed in some examples is a method performed by a relay station, the method including receiving at a relay station a data packet transmitted from a base station to a subscriber station; receiving a non-acknowledgement (NACK) message transmitted from the subscriber station to the base station in response to the data packet; receiving resource allocation information transmitted from the base station to the subscriber station; and transmitting, in response to the received NACK message at the transmission time, the data packet to the subscriber station in a resource allocation allocated for a retransmission of the data packet from the base station to the subscriber station, wherein the resource allocation is determined from the resource allocation information.
