WiFi-coordinated LAA-LTE
First Claim
1. A method, comprising:
- receiving, at a WiFi access point of a small cell, a transmission request for transmitting data by a Long Term Evolution (LTE) access point of the small cell;
determining, by the WiFi access point, channel use data indicating traffic on a plurality of channels of an unlicensed LTE band in a wireless network;
selecting, by the WiFi access point, a channel for use in transmitting data by the LTE access point from among the plurality of channels using the determined channel use data;
at a second time prior to a first time, determining, by the WiFi access point, whether the channel is available for the LTE access point to transmit the data for a duration after the first time;
in response to determining the channel is available, reserving, by the WiFi access point, the channel for transmission for the duration after the first time; and
transmitting, by the WiFi access point, an indication that the channel is ready for transmission to the LTE access point.

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, by a WiFi access point of a small cell, channel use data indicating traffic on a plurality of channels of an unlicensed Long Term Evolution (LTE) band; selecting, by the WiFi access point, a channel for a LTE access point to transmit data to one or more devices using the determined channel use data; receiving, at the WiFi access point, a transmission window in which to transmit the data from the LTE access point to the one or more devices over the selected channel of the unlicensed LTE band beginning at a first time; at a second time prior to the first time, determining, by the WiFi access point, whether the channel is available for the LTE access point to transmit the data for a duration after the first time based on a channel assessment; in response to determining the channel is available, reserving, by the WiFi access point, the channel for transmission for the duration after the first time; and transmitting, by the WiFi access point, an indication that the channel is available for transmission to the LTE access point. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16)

17. A method, comprising:
-
receiving, at a WiFi access point of a small cell configured to select a channel for a Long Term Evolution (LTE) access point of the small cell for transmitting data over an unlicensed LTE band, a transmission window in which to transmit data from the LTE access point to one or more devices over the selected channel of the unlicensed LTE band beginning at a first time, wherein the LTE access point shares the channel with the WiFi access point of the small cell, wherein the channel is selected by; determining, by the WiFi access point, channel use data indicating traffic on a plurality of channels of the unlicensed LTE band; selecting, using the WiFi access point, the channel using the determined channel use data; calculating, by the WiFi access point, 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, by the WiFi access point, whether the channel is available for the LTE access point to transmit the data for a duration after the first time based on a channel assessment; and in response to determining the channel is available, informing, by the WiFi access point, the LTE access point to transmit a preamble sequence and reserve the channel. - View Dependent Claims (18, 19, 20)
