1. A method comprising:
- providing, from a first node that operates according to a first radio access technology (RAT) to a second node that operates according to a second RAT, a first schedule requesting a first portion of a subsequent time interval for transmission in an unlicensed frequency band;
receiving, at the first node from the second node, at least one second schedule requesting at least one second portion of the subsequent time interval for transmission in the unlicensed frequency band by at least one third node that operates according to the second RAT; and
transmitting, from the first node, signals in the unlicensed frequency bands during a third portion of the subsequent time interval that is determined based on the at least one second portion.

Abstract
A first node that operates according to a first radio access technology (RAT) provides a first schedule to a second node that operates according to a second RAT. The first schedule requests a first portion of a subsequent time interval for transmission in an unlicensed frequency band. The first node receives one or more second schedules from a second node. The one or more second schedules request one or more second portions of the subsequent time interval for transmission in the unlicensed frequency band. The first node transmits signals in the unlicensed frequency bands during a third portion of the subsequent time interval that is determined based on the at least one second portion.

17. A first node that operates according to a first radio access technology (RAT), the first node comprising:
-
a processor to generate a first schedule requesting a first portion of a subsequent time interval for transmission in an unlicensed frequency band; and a transceiver to provide the first schedule to a second node that operates according to a second RAT, receive at least one second schedule from the second node requesting at least one second portion of the subsequent time interval for transmission in the unlicensed frequency band by at least one third node that operates according to the second RAT, and transmit signals in the unlicensed frequency bands during a third portion of the subsequent time interval that is determined based on the at least one second portion. - View Dependent Claims (18, 19, 20, 21, 22, 23)

24. A first node that operates according to a first radio access technology (RAT), the first node comprising:
-
a transceiver to receive, from a second node that operates according to the first RAT, at least one first schedule requesting at least one first portion of a subsequent time interval for transmission in an unlicensed frequency band by at least one third node according to a second RAT; and a processor to generate a second schedule indicating a second portion of the subsequent time interval, the second schedule being determined based on the at least one first schedule, wherein the transceiver is to transmit the second schedule, and wherein the transceiver is to transmit signals in the unlicensed frequency band during the second portion of the subsequent time interval. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32)
