    摘要: Methods and systems disclosed provide for clear channel assessment of first and second communication channels. In one aspect, a first primary channel has a first frequency spectrum bandwidth and a second primary channel has a second frequency spectrum bandwidth including the first frequency spectrum bandwidth. A method may include performing a first back-off procedure based on whether the first primary channel is idle if a transmission bandwidth for a wireless message is the first frequency spectrum bandwidth, performing a second back-off procedure based on whether the second primary channel is idle if the transmission bandwidth for the wireless message is greater than the first frequency spectrum bandwidth, and transmitting the wireless message based on a completion of the performed back off procedure.

    摘要: A method and system are disclosed that allow for the control of transmission characteristics associated with an exchange of protocol data units (PDUs) between a first wireless device and a second wireless device. The first wireless device determines a recovery time period and transmits the recovery time period to the second wireless device. The second wireless device may determine a time when the first wireless device enters the sleep state, wait for the recovery time period after the determined time, and then transmit a number of PDUs to the first wireless device after an expiration of the recovery time period.

    摘要: Systems, methods, and devices to communicate in a white space are described herein. In some aspects, wireless communication transmitted in the white space authorizes an initial transmission by a device. The wireless communication may include power information for determining a power at which to transmit the initial transmission. The initial transmission may be used to request information identifying one or more channels in the white space available for transmitting data. In some aspects, a device for wireless communication is disclosed. The device may include a data interleaver with at least a first mode and a second mode. The modes may correspond to transmitting using either two or four channels of the white space.
