  • Publication number: 20100202453
    Abstract: A method, system and computer program product for a wireless mobile display digital interface (WMDDI) association procedure that allows establishing and joining more than one multicast group to facilitate the interoperability of multiple client devices based on host and client capabilities. The protocol provides for the exchange and update of capabilities and multicast addresses for layered multicast transmission applications. The system is used for interoperating devices with different capabilities and provides for efficient transmissions by using different multicast addresses mapped to different layers of a bitstream. The protocol adapts to changes in capabilities, in joining/releasing of multicast addresses and in link quality.

  • Publication number: 20100202493
    Abstract: Low-power transmitter and/or receiver devices are provided by sacrificing time and/or frequency diversity in exchange for lower power consumption. When channel conditions indicate that time and/or frequency spreading are unnecessary for transmissions, a transmitter may enter into a power-conservation mode in which transmissions are performed using a time gating scheme or a time repetition scheme. In the time gating scheme, symbols are transmitting just once, rather than a plurality of times, but with increased transmission power. In the time repetition scheme, copies of the same symbol are transmitted a plurality of times on the same frequency on different symbol transmission periods, instead of being retransmitted on different frequencies on different symbol transmission periods. Consequently, the symbol can be generated once and stored for subsequent retransmission, thereby allowing some of the transmitter/receiver chain components can be operated at a lower duty cycle or processing speed to conserve power.

  • Publication number: 20100203905
    Abstract: A power conservation method and system are provided for conserving power in client terminals by using a partitioned proxy server. The client terminal, having low-power and high-power communication interfaces, may power down its high-power communication interface to conserve power. Prior to shutting off its high-power communication interface, the client terminal may assign a partitioned proxy server to act as its proxy. The partitioned proxy server may include remote and local paging proxies which communicate with each other over an IP network. The remote paging proxy receives paging requests from an access point or the communication network and forwards it to the local paging proxy. The local paging proxy then forwards the paging message to the client terminal via a low-power communication interface. Upon receipt of the paging message via its low-power communication interface, the client terminal may power up its high-power communication interface and directly respond to the paging message.

  • Publication number: 20100162070
    Abstract: Devices, systems and methods for optimizing a number of retransmission attempts in a multimedia environment and managing delays in a host MAC layer. In its various aspects, the presently claimed invention includes several methodologies and systems that are configured for determining an optimal retry limit in response to one or both of a packet error rate bound and a latency bound. To the extent that the retry limit is determined with respect to one of the aforementioned boundaries, the presently claimed invention may include determining a confidence level that the non-selected bound will also be met by the selected retry limit. The presently claimed invention details devices, systems and methods optimizing the number of retransmission attempts to ensure delivery of the selected data packets while guarding against undue delays and application disruptions.

  • Publication number: 20100103883
    Abstract: A method for reserving bandwidth in a wireless system is provided. The method includes reserving one or more communications slots between two or more wireless devices communicating in a wireless network and providing preferential access to at least one wireless device across the network according to a first subset of the communications slots. The method also includes providing preferential access to at least one other device across the network during a second subset of the communications slots.

  • Publication number: 20090252130
    Abstract: In embodiments, a one-to-one association is established between a client and a host in a wireless network, such as a wireless local area network or a wireless personal communication network. The client may be a display device. The host may be a cellular telephone. Active association corresponds to the host exclusively using a shared resource of the client. When the association is solid, requests from other hosts to establish an active association are denied. When the association is fragile, such requests are granted. In the case of a semi-solid association, a request from another host to establish an active association causes the client to generate a query to the host currently owning the active association. If the host currently owning the association grants a release, a new active association is established between the requesting host and the client. Otherwise, the request from the other host is denied.

  • Publication number: 20090245280
    Abstract: In embodiments, a transmitting device sends a time reference field to a receiving device when indicating that no more frames will be sent to the receiving device. The time reference informs the receiving device of the length of time that the transmitting device has committed not to transmit to the receiving device. When operating in conformance with the ECMA-368 standard, the time reference allows the transmitting device to control the length of the commitment period after the MORE FRAMES bit is set to zero. In this way, the commitment not to transmit may be made for a shorter time than the time until the beginning of the following Distributed Reservation Protocol (DRP) reservation block or the time to the beginning of the following superframe. The time reference may be added in the Medium Access Control header or included in a vendor-specific message, for example.

  • Publication number: 20090040984
    Abstract: An exemplary method for reserving medium access in an ad hoc network comprises transmitting a reservation request by a reservation owner, the reservation request identifying a reservation allocation, a reservation target, and a reservation type. The reservation type identifies exclusive use of the reservation allocation by the reservation owner and the reservation target during a reservation period. The reservation target may employ a prioritized contention access (PCA) scheme to access the reservation allocation. Alternatively, an idle portion of the reservation allocation may be subdivided into a plurality of slots including even slots and odd slots, and the reservation owner gains access to the idle portion by starting to transmit during an even slot, while the reservation target gains access to the idle portion by starting to transmit during an odd slot.
