WIFI-COORDINATED LAA-LTE
First Claim
1. A method, comprising:
- receiving, at a Long Term Evolution (LTE) access point from a WiFi access point, channel use data indicating traffic on a plurality of channels of an unlicensed LTE band in a wireless network;
selecting, using the LTE access point, a channel for use in transmitting data by the LTE access point from among the plurality of channels based on the channel use data from the WiFi access point; and
providing, from the LTE access point to the WiFi access point, an indication of an upcoming transmission on the selected channel of the unlicensed LTE band.

Abstract
A method includes detecting, using a WiFi access point, channel use data indicating traffic on a plurality of channels of an unlicensed LTE band in a wireless network. The method further includes providing the channel use data to a Long Term Evolution (LTE) access point. The method further includes selecting, using the LTE access point, a channel for use in transmitting data by the LTE access point from among the plurality of channels based on the channel use data from the WiFi access point. The method further includes providing, from the LTE access point, an indication of an upcoming transmission configured to transmit data on the channel to the WiFi access point. The method further includes broadcasting one or more messages from the WiFi access point to one or more WiFi nodes, the one or more messages configured to prevent the WiFi nodes from transmitting on the channel.

7. A method comprising:
-
determining, at a Long Term Evolution (LTE) access point configured to transmit data over an unlicensed LTE band, a transmission window in which to transmit data to one or more devices over a channel of the unlicensed LTE band beginning at a first time; at a second time prior to the first time, determining whether the channel is available for transmission of the data for a duration after the first time based on a channel assessment; in response to determining the channel is available, reserving the channel for transmission for the duration after the first time; and transmitting the data during the transmission window between the first time and an end of the duration. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16)

17. A method, comprising:
-
determining, at a Long Term Evolution (LTE) access point configured to transmit data over an unlicensed LTE band, a transmission window in which to transmit data to one or more devices over a channel of the unlicensed LTE band beginning at a first time; calculating a transmission window size corresponding to one or more timeslots available for transmission in the channel; at a second time prior to the first time, determining whether the channel is available for transmission of the data for a duration after the first time based on a channel assessment; in response to determining the channel is available, transmitting a preamble sequence to synchronize the LTE access point with one or more nodes; reserving the channel for transmission by transmitting a reservation frame, the length of the reservation of the channel based on the transmission window size; and transmitting the data during the transmission window between the first time and the end of a transmission window. - View Dependent Claims (18, 19, 20)
