For example, an apparatus may include a wireless communication unit to receive WLAN load information indicating a load of at least one WLAN controlled by at least one access point (AP), and, based on the WLAN load information, to select between connecting to the AP and connecting to a cellular node. ## Claims ### Claim 1 A user equipment (UE), comprising: a wireless communication radio to receive, from an evolved NodeB (eNB) in an evolved universal terrestrial radio access network (E-UTRAN), a first signal including wireless local area network (WLAN) information, wherein the WLAN information comprises at least one of information of a WLAN channel utilization or information of a WLAN backhaul, the wireless communication radio to receive, from the eNB, a second signal having updated WLAN information; and a controller to determine whether to offload communication from the E-UTRAN to the WLAN through connecting to an access point (AP) of the WLAN, at least in part based on a determination of whether a condition pertaining to the WLAN information occurs, the controller to determine to offload communication from the WLAN to the E-UTRAN through disconnecting from the AP in the WLAN, at least in part based on a determination of whether a condition related to the updated WLAN information occurs. ### Claim 2 (depends on 1) The UE of claim 1, wherein the information of the WLAN backhaul is based on a WLAN backhaul load. ### Claim 3 (depends on 1) The UE of claim 1, wherein the controller is to determine to offload communication from the E-UTRAN to the WLAN, at least in part based on a determination that a value which is based on a WLAN backhaul load is higher than a threshold. ### Claim 4 (depends on 1) The UE of claim 1, wherein the controller is to determine to offload communication from the WLAN to the E-UTRAN, at least in part based on a determination that the updated WLAN information indicating that a value which is based on a WLAN backhaul load meets a criterion with respect to a threshold. ### Claim 5 (depends on 1) The UE of claim 1, wherein the WLAN information is to be received from the eNB as part of a radio resource control (RRC) signaling message. ### Claim 6 (depends on 1) The UE of claim 1, wherein the wireless communication radio is to receive, from the eNB, a third signal including cellular load information associated to a load of a cellular network controlled by the eNB. ### Claim 7 A method, employed by a user equipment (UE), comprising: receiving, from an evolved NodeB (eNB) in an evolved universal terrestrial radio access network (E-UTRAN), a first signal including wireless local area network (WLAN) information, wherein the WLAN information comprises at least one of information of a WLAN channel utilization or information of a WLAN backhaul; determining whether to offload communication from the E-UTRAN to the WLAN through connecting to an access point (AP) of the WLAN, at least in part based on a determination of whether a condition pertaining to the WLAN information occurs; receiving, from the eNB, a second signal having updated WLAN information; and determining to offload communication from the WLAN to the E-UTRAN through disconnecting from the AP in the WLAN, at least in part based on a determination of whether a condition related to the updated WLAN information occurs. ### Claim 8 (depends on 7) The method of claim 7, wherein the information of the WLAN backhaul is based on a WLAN backhaul load. ### Claim 9 (depends on 7) The method of claim 7 comprising determining to offload communication from the E-UTRAN to the WLAN, at least in part based on a determination that a value which is based on a WLAN backhaul load is higher than a threshold. ### Claim 10 (depends on 7) The method of claim 7 comprising determining to offload communication from the WLAN to the E-UTRAN, at least in part based on the determination that the updated WLAN information indicating that a value which is based on a WLAN backhaul load meets a criterion with respect to a threshold. ### Claim 11 (depends on 7) The method of claim 7, wherein the WLAN information is to be received from the eNB as part of a radio resource control (RRC) signaling message. ### Claim 12 (depends on 7) The method of claim 7 comprising: receiving, from the eNB, a third signal including cellular load information associated to a load of a cellular network controlled by the eNB. ### Claim 13 An apparatus of evolved NodeB (eNB) in an evolved universal terrestrial radio access network (E-UTRAN), comprising: one or more processors; and one or more machine-readable medium having instructions stored thereon that, when executed by the one or more processors, cause the eNB to: transmit, to a user equipment (UE), wireless local area network (WLAN) information as part of a first radio resource control (RRC) signaling message, wherein the WLAN information comprises at least one of information of a WLAN channel utilization or information of a WLAN backhaul; and transmit, to the UE, updated WLAN load information as part of a second RRC signaling message, wherein the updated WLAN load information comprises updated information of the WLAN backhaul. ### Claim 14 (depends on 13) The apparatus of claim 13, wherein the information of the WLAN backhaul is based on a WLAN backhaul load. ### Claim 15 (depends on 13) The apparatus of claim 13, wherein the instructions, when executed, cause the eNB to transmit cellular load information corresponding to a load of a cellular network controlled by the eNB.
