Abstract: Certain aspects of the present disclosure propose techniques for independently signaling features supported by a user equipment (UE) in different duplexing modes. The UE may be capable of communicating in frequency division duplexing (FDD) and time division duplexing (TDD) modes. The UE may obtain a FDD-specific feature group indicators (FGIs) set and a TDD-specific FGIs set, and signal at least one of the FDD-specific FGIs set or TDD-specific FGIs set. In addition, the UE may take one or more actions to reduce the likelihood of transitioning to a mode of operation that is different from its current mode of operation.

Abstract: A CS fallback procedure handles conflict that may arise when handover operations occur during CS fallback. If CS fallback is initiated for an access terminal and handover of that access terminal is then initiated before the CS fallback completes, the target for the handover is informed of the CS fallback so that the target may perform the appropriate CS fallback operations.

Abstract translation: CS回退过程处理在CS回退期间发生切换操作时可能出现的冲突。 如果为接入终端发起CS回退，然后在CS回退完成之前启动该接入终端的切换，则向CS回退通知切换目标，以便目标可以执行适当的CS回退操作。

Abstract: Devices and methods are provided for optimizing the timing of multi-mode system scans in a wireless communication environment. In one embodiment, the method may involve determining at least one of location and movement of a mobile entity (ME). The method may involve adjusting a timer between preferred system scans based on the at least one of the location and the movement of the ME. For example, determining may involve utilizing a movement sensor (e.g., an accelerometer and/or a voltage-controlled oscillator accumulator) to detect the movement of the ME, and/or receiving signals from a Global Positioning System or the like.

Abstract: A method is provided for a particular multi-radio meshed node to discover a route to a peer multi-radio meshed node in a wireless multi-hop network including a plurality of multi-radio meshed nodes. Each of the multi-radio meshed nodes each includes a plurality of radio modules, and each radio module comprises an interface. The particular multi-radio meshed node transmits route request (RREQ) messages from each interface of a particular multi-radio meshed node. When a particular recipient multi-radio meshed node receives at least one of the route request (RREQ) messages, it generates a reverse route to the particular multi-radio meshed node. A peer-to-peer route is established when the particular multi-radio meshed node receives a route reply (RREP) message and can then be used to forward traffic to and from the destination node.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. In one aspect, an apparatus supports multiple radio access technologies (RATs), and has a single radio configured to provide a circuit-switched (CS) and packet switched (PS) connectivity. The apparatus sends a request for combined registration to a first network entity and detects whether circuit-switched fallback (CSFB) support is available to the apparatus in the first network. The request for combined registration may include a request for concurrent registration with a packet switched (PS) service of the first network and a CS service of a second network using a second RAT. The apparatus enables a single radio LTE (SR-LTE) operation, to maintain the availability of PS service in the first network, when the requested combined registration is not accepted by the first network entity. The SR-LTE operation and related techniques provided herein enable CS and PS service for voice- centric devices without regard to network support for CSFB operation.

Abstract: Certain aspects of the disclosure relate generally to search of radio access technologies (RAT). For example, certain aspects of the present disclosure relate to a technique for performing higher priority radio access technology (RAT) searches in areas having a plurality of overlapping RATs, such as Global System for Mobile communications (GSM) and Long Term Evolution (LTE). According to certain aspects, a user equipment (UE) may be configured to periodically search for higher priority RATs in neighboring cells. According to certain aspects, upon finding a higher priority RAT cell, the UE may be further configured to evaluate, or "pre-evaluate", criteria for cell reselection from found cell to the currently camped cell, while still camped on the current cell. The UE may be configured to decide whether or not to switch to the found cell based on the evaluation.
