Abstract: Heat dissipation in vertically arrayed host device configurations can be improved through inclusion of heat sinks having split-stream fin architectures. The split-stream fin architecture includes two or more sets of angled fins separated by a central conduit, which allows for more efficient inflow and/or expulsion of convection cooling air over the heat sink. The split-stream fin arrangement may include inwardly angled fins in order to draw convection cooling air inwards from horizontal inlets, in which case warm exhaust is expelled through the central conduit. Conversely, the split-stream fin arrangement may include outwardly angled fins, which draw convection cooling air from the central conduit, and expel warm air through horizontal exhausts. The split-stream fin arrangements function well when host devices are configured horizontally, which allows for more flexible host device configurations.

Abstract: Signal (SIF) field capacity can be significantly increased by encoding SIG field data using two streams in accordance with a space-time block code (STBC) encoding scheme. Dual-stream SIG field encoding allows for the utilization of higher order modulation schemes, such as quadrature phase-shift keying (QPSK), which increases SIG field capacity. Dual-stream encoded SIG fields are transmitted using an omnidirectional beam to allow mobile stations to accurately decode the SIG field irrespective of their spatial location.

Abstract: Transmit point (TP) associations can be assigned to user equipments (UEs) by including a TP association variable within a sum-utility function traditionally used for computing beamforming weight vector assignments. Accordingly, maximization of the sum-utility function obtains both TP associations and beamforming weight vector assignments. Additionally, the sum-utility function may be computed in accordance with channel statistics, rather than channel state information (CSI), thereby reducing coordinated multi-point transmission (CoMP) related overhead.

Abstract: Measurements and Channel State Information (CSI) feedback are configured using communications between a network and user equipment (UE). The communications includes a first signaling from a network component to the UE indicating one or more reference signal (RS) resource configurations, a second signaling indicating one or more interference measurement (IM) resource configurations, and a third signaling indicating a CSI report configuration, wherein the CSI report configuration indicates a subset of the one or more RS resource configurations and a subset of the one or more IM resource configurations.

Abstract: A mobile relay node having communication sessions with a plurality of wireless mobile device (UEs) and a communication link to a source base station via a first communication link is located within a moving vehicle. As the vehicle moves from the coverage area of the source base station to the coverage area of a target base station, the relay node performs a hand off process that initiates a second communication link with the target while maintaining and continuing to relay communications between the UEs and the source. Once the second communication link is active, the relay node switches UE traffic from the source base station to the target base station over the second communication link, and then releases the first communication link.

Abstract: Error drift during compressed domain watermarking can be reduced by embedding watermarking symbols in macroblocks that have relatively low influence on pixel values of other macroblocks during video decompression. This influence may be quantified using compression influence values (CIVs), which may be computed/assigned based on prediction dependency relationships amongst the various macroblocks in a sequence of frames. To wit, high CIVs are assigned to macroblocks that heavily influence the pixel values of other macroblocks during intra-frame/inter-frame prediction, while low CIVs are assigned to macroblocks that have little influence over the pixel values of other macroblocks. Macroblocks having the lowest CIVs may be selected for embedding compressed domain watermarking bits/symbols. Alternatively, macroblocks having high CIVs may be excluded from a pool of candidate macroblocks that are eligible for carrying embedded compressed domain watermarking bits/symbols.
