SYSTEMS, METHODS AND DEVICES FOR CHANNEL RESERVATION
First Claim
1. An evolved node B (eNB) for sharing unlicensed spectrum comprising:
- a processor configured to;
select a set of licensed assisted access (LAA) compatible devices that will receive a set of messages over a shared communication channel;
select a placement of a request to reserve the shared communication channel within an LAA protocol;
transmit the request to reserve the shared communication channel using protocol recognized by one or more radio access networks (RANs) in the unlicensed spectrum; and
transmit, using the LAA protocol over the shared communication channel, the set of messages.

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).

12. A network controller for coexisting on a shared medium with a non-Third Generation Partnership Project (non-3GPP) compatible protocol and a Third Generation Partnership Project (3GPP) compatible protocol, the network controller configured to:
-
send a first reservation message over the non-3GPP compatible protocol to cause a reservation of the shared medium for a first period; transmit first data to a set of user equipment (UE) over the 3GPP compatible protocol; determine to extend the reservation for a second period; and send a second reservation message over the non-3GPP compatible protocol to reserve the shared medium for the second period. - View Dependent Claims (13, 14, 15, 16, 17)

18. A method of reserving a shared communication channel comprising:
-
broadcasting, using a first protocol, a first request to reserve a wireless band of frequencies for a duration of time, the wireless band of frequencies shared with the first protocol and a second protocol; transmitting first data, for a first portion of the duration of time over the second protocol, to a set of mobile devices to receive a set of communications over the wireless band of frequencies; broadcasting, using the first protocol, a second request to reserve the wireless band of frequencies for a remaining portion of the duration of time; and transmitting second data, for a second portion of the duration of time over the second protocol, to the set of mobile devices over the wireless band of frequencies. - View Dependent Claims (19, 20)
