Abstract:
Methods and apparatus to enable an extensible and scalable control channel for wireless networks. In one embodiment, an Enhanced Physical Downlink Control Channel (ePDCCH) is disclosed that is implemented with a flexible number of Physical Resource Blocks (PRBs). Advantages of the ePDCCH include, for example: more efficient spectral utilization, better frequency management across multiple serving entities (e.g., base stations and remote radio heads), and extensible payload capabilities that can scale to accommodate higher or lower control information payloads, as compared to prior art PDCCH solutions.
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:
Methods and apparatus for identification of macro-cells and subordinate transmission nodes. In one embodiment, the methods and apparatus are configured for use within a long term evolution (LTE/LTE-A) network, and include a scrambling technique which can facilitate advanced capabilities in which the subordinate nodes possess unique cell identities from the macro-cell. The use of unique scrambling sequences allows subordinate node switching and other advanced multi-antenna techniques in heterogeneous networks. The disclosed methods and apparatus further allow for distinction and detection of signals transmitted from low-power RRHs, femto-cells, etc. and advantageously achieve greater interference randomization gain.
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:
Distributed computing in a wireless communication system. Reports may be received from a plurality of nodes in a wireless communication system. Each respective report may include information regarding computing resources at the respective node. A notification of a request for a computing resource may be received from a first wireless user equipment device. A first node may be selected from the plurality of nodes to provide the computing resource based on the reports received from the plurality of nodes. The first node may be assigned to provide the computing resource.
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. 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 receive reference signals from different antenna nodes in its vicinity, compute receive signal strength levels, and 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.
