Abstract: A device for facilitating cellular-wireless local area network (WLAN) interworking may include at least one processor circuit. The processor circuit may be configured to receive a packet including a first tunnel identifier and addressed to a user equipment (UE). The processor circuit may be configured to identify a radio bearer associated with the first tunnel identifier, where the radio bearer is configured to facilitate transmission of the packet to the UE via cellular communications. The processor circuit may be configured to determine whether the radio bearer has been offloaded over a WLAN. The processor circuit may be configured to, when the radio bearer has been offloaded over the WLAN, identify a second tunnel identifier mapped to the radio bearer; encapsulate the packet based on the second tunnel identifier, where the encapsulated packet includes the second tunnel identifier; and transmit the encapsulated packet to the UE over the WLAN.

Abstract: A communication device and method for offloading communications from a first communication network to a second communication network. The offloading decision can be based on one or more utility values and/or one or more utility sum values. The utility values and/or utility sum values can be defined in a communication framework. The communication framework can be, for example, Access Network Discovery and Selection Function (ANDSF) framework. The offloading of communication can be from a Long-term Evolution (LTE) network to a wireless local area network (WLAN), or vice-versa. The communication framework can include, for example, utility, utility sum, positional, movement, signal quality, connection duration, data rate, and/or quality of service (QoS) parameters.
Abstract translation: 一种用于将通信从第一通信网络卸载到第二通信网络的通信设备和方法。 卸载决定可以基于一个或多个效用值和/或一个或多个效用总和值。 效用值和/或效用总和值可以在通信框架中定义。 通信框架可以是例如接入网络发现和选择功能（ANDSF）框架。 通信的卸载可以是从长期演进（LTE）网络到无线局域网（WLAN），反之亦然。 通信框架可以包括例如效用，效用总和，位置，移动，信号质量，连接持续时间，数据速率和/或服务质量（QoS）参数）。

Abstract: Various methods and systems are provided for time domain coexistence of RF signals. In one example, among others, a method includes obtaining access to a WLAN channel during a free period of a coexisting cellular connection, providing a RDG to allow another device to transmit for a duration corresponding to at least a portion of a TXOP, and receiving a transmission during the duration. In another example, a method includes obtaining access to a WLAN channel during a transmission period of a coexisting cellular connection and providing a protection frame to defer transmissions from another device for a duration corresponding to at least a portion of a TXOP. In another example, a method includes determining a shift of a BT transaction based at least in part upon a schedule of cellular communications and shifting at least a portion of the BT transaction based upon the determined shift.
