  • Publication number: 20140189035
    Abstract: The time required to login to a remote or virtual desktop can be reduced by caching image data in a persistent memory location in-between remote desktop sessions. For instance, image data related to an image displayed on a client device during a first virtual desktop session may be cached after terminating the first virtual desktop session. The cached data can then be used to display the same image, or a correlated image, on the client device during a subsequent remote desktop session, thereby avoiding the need to re-transport the image data over a network. In a similar manner, cached image data can be shared between multiple users sharing a common local area network (LAN) in order to improve collective virtual desktop performance.

  • Publication number: 20130223344
    Abstract: A single hybrid automatic repeat request (HARQ) entity can be associated with multiple serving units to achieve lower complexity user-side signal processing during multi-point communication. Additionally, configuring a single HARQ entity to establish HARQ operations with multiple serving units may achieve lower latency communication when users are engaging in multi-point communications, such as coordinated multi-point transmission/reception (CoMP). HARQ entity associations and/or reconfigurations can be achieved through radio resource control (RRC) signaling.

  • Publication number: 20130223012
    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.

  • Publication number: 20130216002
    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.

  • Publication number: 20130201937
    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.

  • Publication number: 20130195005
    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.
