Abstract: Embodiments of a packet-data network (PDN) and methods for RAN-agnostic multimedia content distribution are generally described herein. In some embodiments, the PDN may dynamically distribute IP packets of a single service flow to two or more RANs associated with two or more available radio links for subsequent transmission to a user terminal when each of the two or more available radio links meet the QoS requirements of the single service flow.

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.

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).

Abstract: The particular frame in a super-frame using orthogonal frequency division multiple access techniques will contain system configuration information in the super-frame header. This super-frame header may be located at a fixed offset from the initial preamble of the frame. In some embodiments, the system configuration information may be located in a broadcast channel section of the super-frame header. In some embodiments, the particular frame may overlap a legacy OFDMA frame in time and in OFDMA sub-channels, so that the two frames share some time and sub-channel resources.
