Abstract: A user equipment (UE) can reserve shared spectrum between two wireless protocols upon the request from a tower. For example, an enhanced node B (eNB or eNodeB) transmits a message to associated UEs including a set of candidate UEs, a length of time to reserve, and a frequency band to use. UEs perform medium sensing on the specified spectrum if a UE finds its identifier in the set of candidate UEs. Candidate UEs transmit a clear to send (CTS) message with channel reservation information if the medium is idle. A result of the success or failure of the CTS transmission attempt is sent back to the eNB. Upon receiving the feedback information from the UEs, the eNB starts sending data to those UEs that sent the positive feedback on the channel reservation.

Abstract: This disclosure describes systems, methods, computer readable media, and/or apparatus related to encoding wireless communication preamble structures with cyclic redundancy check (CRC) that is performed on both a common part, as well as, station specific parts of a signaling field. The signaling field generated by this mechanism may be relatively shorter, resulting in less preamble overhead, than if a separate CRC was to be provided for each of the station specific parts, as well as the common part of the signaling field. In additional embodiments, tail bits may be provided for a combination of the common part of the signaling field and each station specific part of the signaling field. Compared to providing tail bits separately for the common part and each of the station specific parts, removing the tail bits from the tail bits form the common part may result in relatively less overhead of the preamble structure.
