Abstract: A device uses a first protocol to incorporate a reservation of a medium using a second protocol within the bounds of the first protocol. For example, an evolved node B (also known as an e node B or eNB) using a long term evolution over unlicensed spectrum (LTE-U) protocol can be configured to reserve unlicensed spectrum using a (wireless local area network) WLAN message placed within a muting gap within the LAA protocol. In one embodiment, the eNB selects to broadcast the WLAN reservation message using a set of options including: (1) from a control channel region of LAA, (2) from a muting gap indicated by a reservation muting symbol pattern indicator, (3) from a time division duplex (TDD) guard period (GP), (4) from a TDD uplink pilot time slot (UpPTS), (5) from an empty uplink (UL) subframe or (6) from a sounding reference signal (SRS).
