Systems and methods for contention management and quality of service estimation in heterogeneous wireless networks
First Claim
1. A user equipment (UE) configured to:
- receive a maximum access probability that the UE will be able to access a wireless local area network (WLAN) for communication, wherein the maximum access probability is a value received via a 3rd Generation Partnership Project (3GPP) communication link with an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB);
determine that there is a queued transmission for the UE;
in response to determining that there is a queued transmission, determine whether the UE is authorized to access the WLAN using a probability less than or equal to the maximum access probability; and
delay contention for access to the WLAN for at least a pre-backoff duration in response to determining that the UE is not authorized to access the WLAN using the probability less than or equal to the maximum access probability.

Abstract
A user equipment (UE) is configured to receive a maximum probability of accessing a wireless local area network (WLAN) for communication. The maximum probability is received via a 3rd Generation Partnership Project (3GPP) communication link with an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB). The UE is further configured to determine that there is a queued transmission for the UE and, in response to determining that there is a queued transmission, to determine whether the UE is authorized to access to the WLAN using a probability less than or equal to the maximum probability. The UE is further configured to delay contention for access to the WLAN for at least a pre-backoff duration in response to determining that the UE is not authorized.

8. A wireless communication device comprising:
-
communication circuitry configured to communicate with a small cell over a licensed wireless spectrum and an unlicensed wireless spectrum, wherein communicating with the small cell comprises communicating at least a portion of control layer data over the licensed wireless spectrum and communicating at least a portion of user layer data over the unlicensed spectrum; control layer circuitry configured to receive, on the licensed spectrum, contention settings for communicating using the unlicensed spectrum, wherein the contention settings comprise an access probability of the wireless communication device beginning an access procedure for uplink (UL) communication over the unlicensed spectrum; wherein the control layer circuitry is further configured to receive, over the licensed spectrum, additional contention settings comprising a probability of communicating in a downlink (DL) direction over the unlicensed spectrum; and data layer circuitry configured to manage communications on the unlicensed spectrum based on the contention settings. - View Dependent Claims (9, 10, 11, 12)

13. An Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB) comprising:
-
communication session circuitry configured to establish a communication session with a user equipment (UE) over a 3rd Generation Partnership Project (3GPP) link; probability circuitry configured to determine a maximum pre-backoff probability for the UE to communicate with a non-3GPP access point, wherein the maximum pre-backoff probability indicates a maximum probability at which the UE is allowed to transmit data in an uplink (UL) direction to the non-3GPP access point; configuration circuitry configured to send a radio resource control (RRC) message indicating the maximum pre-backoff probability for the UE, wherein the RRC message indicates whether the UE should delay contention for transmission for at least a pre-backoff duration based on the maximum pre-backoff probability; and congestion circuitry configured to detect congestion on a network corresponding to the non-3GPP access point, wherein the congestion circuitry is configured to detect the congestion based on a binary exponential backoff (BEB) window size exceeding a threshold value. - View Dependent Claims (14, 15, 16, 17, 18)
