摘要： Techniques to enable dynamic bandwidth management at the physical layer level while maintaining backwards compatibility in wireless systems is provided. Furthermore, techniques for reducing the occurrence of exposed nodes are provided. A transmitter may transmit a frame including an indication that a PHY layer sub-header defining a bandwidth associated with a channel is present. Furthermore, the transmitter may transmit a third frame after receiving a second frame from a receiver to indicate to legacy stations that the TXOP was successful.

摘要： Embodiments include systems and methods for allocating time to a plurality of devices in the network of a piconet controller. Embodiments comprise selectively directing a steerable antenna beam of the piconet controller to a plurality of devices in succession during a polling process to receive time allocation requests from one or more of the devices. Subsequent to the polling process, a grant procedure is performed wherein a device is granted permission to transmit in a subsequent time interval. Also during the grant process, one or more devices are instructed to receive from the device granted permission to transmit. The polling process and the grant process occur in the same superframe.
