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 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 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: 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.
