20100153553 | DYNAMIC RESOURCE SHARING AMONG MULTIPLE WIRELESS DEVICES - A system and method that enables two or more hosts so that they can share a resource, such as a display. Client allocates a portion of the resource to each of the eligible hosts. This allocated size is negotiable among host(s) and the client. Client may request the hosts to scale down/up resource utilization based on the allocated portion of the resource being shared. This helps keep the client implementation simple. In this case, client maintains the allocation vector for each host. This allocation vector is used to keep track of the resource sharing. While this is a preferred approach, it is possible that “intelligent” client may actually modify resource utilization for a given host based on the negotiated allocation. | 06-17-2010 |
20100202334 | SYSTEMS AND METHODS FOR REDUCING POWER CONSUMPTION USING A VARIABLE CONSTRAINT LENGTH CONVOLUTIONAL ENCODER - Systems and methods are provided for selecting transmission parameters used in the transmission of a communication signal in a wireless communications device. In one embodiment, a computer-implemented method for determining a convolutional code constraint length and/or a modulation type is provided. The method includes obtaining a channel condition for a channel associated with transmission of the communication signal. Based at least in part on the channel condition, the method includes selecting a convolutional code constraint length and/or a modulation type for transmitting the communications signal. In some embodiments, the method also includes selecting a data rate for transmitting the communications signal. | 08-12-2010 |
20100202493 | LOW POWER ULTRA WIDEBAND TRANSCEIVER - 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. | 08-12-2010 |
20100203905 | PARTITIONED PROXY SERVER FOR FACILITATING POWER CONSERVATION IN WIRELESS CLIENT TERMINALS - 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. | 08-12-2010 |
20100246543 | SYSTEM AND METHOD OF TRANSMITTING AND RECEIVING DATA FRAMES - A method of transmitting a data frame is disclosed and may include transmitting a preamble, transmitting a physical layer convergence protocol (PLCP) header, and transmitting a plurality of MAC protocol data units (MPDUs). Each MPDU may be configured to reset a convolutional decoder state after each MPDU. The method may also include transmitting an MPDU aggregation header. The MPDU aggregation header may include a count of packed MPDUs, an array of offsets, an array of lengths, a frame check sequence (FCS) for the MPDU aggregation header, a group of tail bits, or a combination thereof. Further, an end of the MPDU aggregation header may be aligned to an interleaved symbol boundary. | 09-30-2010 |

20110013644 | SYSTEMS AND METHODS FOR PROVIDING RESOURCE ALLOCATION MEETING COMMUNICATION CONSTRAINTS FOR MULTI-HOP NETWORK DATA FLOWS - Systems and methods identify a multi-hop network data path with sufficient available resources at each node along the data path to facilitate desired end-to-end data flow. Embodiments operate to identify resource constraints for meeting QoS or other communication requirements at each node of a multi-hop data path and propagate the resource constraint information within the network for use in identifying data paths suitable for supporting a desired end-to-end data flow. A resource allocation algorithm operable to allocate resources to achieve an end-to-end data flow meeting the communication requirements is implemented according to embodiments. A resource allocation algorithm of embodiments operates to ensure efficient use of the available resources so that desired conditions are satisfied when the resource requirements are met at each intermediate node for the upstream and downstream links and also both links simultaneously. | 01-20-2011 |
