METHOD OF SHARING RADIO RESOURCES FOR LICENSED ASSISTED ACCESS IN UNLICENSED SPECTRUM AND RELATED DEVICES USING THE SAME
First Claim
1. A method of sharing radio resources for licensed-assisted access (LAA) in an unlicensed spectrum used by a user equipment (UE), the method comprising:
- transmitting or receiving, through a LTE protocol, a first data in a licensed spectrum;
transmitting or receiving, through the LTE protocol, a first control signal in the licensed spectrum for receiving a second data in an unlicensed spectrum;
transmitting or receiving, through a LTE-unlicensed (LTE-U) protocol, the second data in the unlicensed spectrum within a first time window without transmitting a random access (RA) request; and
stopping transmitting, through a Wi-Fi protocol, any RA request as long as the first time window has not expired.

Abstract
A method of sharing radio resources for licensed assisted access (LAA) in unlicensed spectrum and related devices using the same are provided. In one of the exemplary embodiments, the disclosure is directed to a method used by a user equipment for sharing radio resources for LAA in an unlicensed spectrum. The method would include not limited to transmitting or receiving, through a LTE protocol, a first data in a licensed spectrum; transmitting or receiving, through the LTE protocol, a first control signal in the licensed spectrum for receiving a second data in an unlicensed spectrum; transmitting or receiving, through a LTE-unlicensed (LTE-U) protocol, the second data in the unlicensed spectrum within a first time window without transmitting a random access (RA) request; and stopping transmitting, through a Wi-Fi protocol, any RA request as long as the first time window has not expired.

6. A method of sharing radio resources for licensed-assisted access (LAA) in an unlicensed spectrum used by a base station, the method comprising:
-
transmitting, through an inter-base station interface, a first control signal to configure a contention free period for transmitting or receiving in an unlicensed spectrum without any contention; transmitting, through a LTE protocol, a second control signal for transmitting or receiving in the unlicensed spectrum without any contention; transmitting or receiving within the contention free period in the unlicensed spectrum; and stopping any transmitting or receiving wirelessly in the unlicensed spectrum outside the contention free period. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)

14. A method of sharing radio resources for licensed-assisted access (LAA) in an unlicensed spectrum used by a Wi-Fi access point (AP), the method comprising:
-
receiving, through an inter-base station interface, a first control signal to configure a contention free period for transmitting or receiving in an unlicensed spectrum without any contention; transmitting, through a Wi-Fi interface, a second control signal indicating a start of the contention free period during which no random access (RA) request is processed; receiving, through the Wi-Fi interface, a RA request for a contention after the contention free period has expired; and serving the RA request in response to the contention being successful. - View Dependent Claims (15, 16, 17, 18, 19, 20)
