A method of transmitting a data frame is disclosed and may include transmitting a preamble, transmitting a physical layer convergence protocol (PLCP) header, and transmitting a plurality of MAC protocol data units (MPDUs). Each MPDU may be configured to reset a convolutional decoder state after each MPDU. The method may also include transmitting an MPDU aggregation header. The MPDU aggregation header may include a count of packed MPDUs, an array of offsets, an array of lengths, a frame check sequence (FCS) for the MPDU aggregation header, a group of tail bits, or a combination thereof. Further, an end of the MPDU aggregation header may be aligned to an interleaved symbol boundary.

Methods and apparatuses for interference management between multiple wireless networks are disclosed. The apparatuses, and methods for doing the same, communicate with one or more wireless devices in each of first and second wireless networks, the first and second wireless networks having a common spectrum and different air interface protocols, and generate a message for transmission into the first wireless network to suppress transmission in the first network and to reserve a medium for wireless transmissions in the second wireless network.

摘要:
In embodiments, an adaptive tone erasure technique is applied to orthogonal frequency division multiplexing (OFDM) communications, such as ECMA-368 standard ultra-wideband (UWB) communications. A transmitter obtains jammed sub-carrier information and calculates an erasure mask. The jammed sub-carriers are nulled before transmitting to a receiver. In accordance with the erasure mask, bits falling on the jammed sub-carriers are replaced by erasure bits before interleaving, keeping the interleaver block size constant notwithstanding variations in the number of the jammed sub-carriers. The receiver also obtains the jammed sub-carrier information and the erasure mask. After the receiver deinterleaves the constant size blocks, it decodes the data without the erasure bits. The transmitter may detect the jammed sub-carriers itself, or obtain the information from the receiver. The receiver similarly may detect the jammed sub-carriers itself, or obtain the information from the transmitter.
