Abstract: Methods and apparatus for improved packet data flow mobility and packet data distribution and collection across heterogeneous networks. In one embodiment, a source device with one or more wireless interfaces receives data to be transmitted to a target device. The device sequences the received data with corresponding packet sequence numbers according to characteristics of the service providing the data. The sequenced data is classified according to application/service requirements (e.g., minimum Quality of Service requirements, service type, etc.). The classified data is assigned to available network interfaces, which can support the classifications of the data. The data is transmitted over the assigned network interfaces to the corresponding receiving interface. The data is collected and reassembled according to the packet sequence number at the target destination.

Abstract: Techniques for managing detection, dynamic allocation, and sharing of available spectrum via cognitive radio systems and dynamic spectrum sharing. In some cases, RF carriers (e.g., secondary carriers or secondary cells) are not permanently assigned to base stations, user terminals, or the network. A base station can request allocation of secondary carriers using a reservation request. The assigned secondary carriers can be released and made available for assignment to another base station or radio access network.

Abstract: In a wireless network, simultaneous support of distributed and contiguous sub-carrier allocation may be accomplished in the same sub-frame or time zone. Techniques are described herein that can be used to allocate distributed and/or contiguous basic (physical) resource blocks to users by specifying a codebook index and parent node. Techniques are described herein that can be used to flexibly set a number of sub-channels over which a subscriber station indicates a channel quality indicator to a base station. Sub-channels may be represented as nodes and may be grouped to include a parent node and child nodes. By specifying a code book to use and a parent node, the channel quality indicator of the parent and children nodes can be indicated.

The method may also include determining at least three different RSRPs corresponding to the at least three different reference signals. The at least three different RSRPs may be level 3 filtered to produce at least three corresponding filtered powers. The UE may report a maximum of the at least three corresponding filtered powers to the distributed antenna system.

The eDAS includes geographically-separated antenna nodes and each of the antenna nodes has a plurality of antenna elements. The base station may perform physical-layer baseband processing for each of the antenna nodes at a centralized processing location, and may cause the antenna nodes to transmit reference signals in accordance with a multiplexing scheme to allow user equipment to perform channel estimation for the antenna elements of any one or more of the antenna nodes. The base station may also cause the antenna nodes to transmit signals having synchronization codes to allow the user equipment to synchronize with the antenna elements of any one or more of the antenna nodes. In some embodiments, the base station may communicate with the antenna nodes over a physical-layer interface.

Abstract: Methods and apparatus for detecting and mitigating interface conditions at a multi-radio device. In one embodiment, a multi-radio device monitors and detects an in device-coexistence (IDC) interference condition which is, for example, caused by concurrent operation of radios. In response, the device notifies a network entity (e.g., a Long Term Evolution (LTE) eNodeB) of the detected IDC condition. Upon receiving the notification of the IDC condition, the network entity may implement or invoke a mitigation scheme in order to reduce the amount of IDC experienced at the client device.

Abstract: Methods and apparatus for dynamic sharing of resources such as radio frequency (RF) spectrum in a wireless system. In one embodiment, the sharing is conducted among a number of base stations (e.g., eNodeBs or Access Points (APs)), or among different radio access technologies (RATs). In one implementation, the sharing is accomplished through reservation of new RF carriers, and temporary assignment (and release) of one or more RF carriers to the multi-carrier enabled radio access systems or base stations. Such dynamic spectrum sharing allows opportunistic use of additional RF carriers in a multi-carrier system as opposed to permanent availability to the eNodeB or AP regardless of their effective usage.

Abstract: A coordinated multipoint (CoMP) transmission radio network is provided. Each cell in the CoMP network may include antenna nodes distributed at different geographical locations and coupled to a common baseband processing unit via an optical fiber link. When operating a user device in the CoMP network, the device may register with a neighboring baseband unit and may be served using at least one antenna node. The device may continuously receive reference signals from different antenna nodes in its vicinity and compute receive signal strength levels. The device may report the measurements to the corresponding baseband unit. The baseband unit may then switch appropriate antennas in/out of use based on the measured results. If desired, the device may be served using more than one antenna node that may or may not be part of the same cell (e.g., the device may be served using antenna nodes coupled to different baseband units).
