    摘要: A communication system includes first and second devices, where a processor of at least one of the first device and the second device is configured to establish a superframe having a superframe duration (Ts) and transmit a beacon by the first device during each of the superframe duration (Ts); scan by the second device all sectors (Nbeam) by scanning each sector for a superframe duration (Ts) and repeating a jump sequence. The jump sequence has a sequence duration (Ttotal) which is equal to a sum of a control duration (Tc) of a control channel and durations of data channels (KTd). The processor is further configured to find the first device by the second device during a find time (Tf), where the control duration (Tc) is greater than the durations of data channels (KTd).

    摘要: In a communication network (100), a method (400) of reserving X slots (610) for transmitting data from a source device (110A) to a destination device (110D) via multi-hop relay includes sending a first hop reservation request from the source device (110A) to a second device (110), for transmitting data from the source device to the destination device. The first hop reservation request identifies the source device, the destination device, and X proposed slots (610) to be reserved for the first hop. The source device then receives a first message, addressed to the source device from the second device, indicating that the first hop reservation request is pending and that the X slots proposed by the source device have been reserved by the second device. Later, the source device receives a subsequent message indicating whether a final hop reservation request has been accepted by the destination device.

    摘要: The present invention provides a system (600), device (500) and method (400) for automatic partner selection in an existing Cooperative MAC (CMAC) protocol, which uses the Ready-to-Send (RTS), Clear-to-Send (CTS) and Partner-Clear-to-Send (PCTS) handshaking to establish cooperation. The present invention enables a “best” partner/relay (500.R.k) who is also willing to cooperate to relay information to a destination (500.D.J) for the transmitting device (i.e., the source), without the source (500.S.i) making a decision on partner selection. That is, the present invention provides a new mechanism by which the best partner/relay (500.R.k) that is also willing to cooperate will “step in” automatically without the source's involvement in selection of the partner/relay (500.R.k). This mechanism is contention-based and the partner is “selected” using local information only in a fully distributed manner.

    摘要: Under the present invention, a wireless component such as an access point or a mobile device is configured to manage the buffering of newly transmitted TCP packets. Specifically, the wireless component can receive both forwarded TCP packets and newly transmitted TCP packets. If a set of newly transmitted TCP packets is received out of order(i.e., before a set of previously transmitted TCP packets that must be forwarded), one out of order (newly transmitted) TCP packet will be passed for each of a quantity of tokens present on the wirelesss component. Each out of order TCP packet that is not passed will be buffered. Once a previously requested forwarded TCP packet is received and passed, the quantity of tokens is restiored to a predetermined quantity, and a commensurate number of buffered TCP packets can be passed.

    摘要: A method enables a wireless device (310) to rendezvous with another wireless device (320) through a wireless network (330), where activation schedules of the wireless devices are not synchronized. The method includes determining a number of time units in each cycle of multiple communication cycles, identifying active time units in each cycle during which the first wireless device enters an active mode, and identifying inactive time units in each cycle during which the first wireless device enters an inactive mode. The sum of the active time units and the inactive time units equals the number of time units in each cycle. A first active time unit in each cycle occupies a same position in the cycle as an active time unit in a previous consecutive cycle. Also, a second active time unit in each cycle occupies a different position in the cycle than any active time unit in the previous consecutive cycle.

    摘要: The application describes a method to merge two wireless networks in which each terminal gets a beacon slot within the beacon period. In order to merge two networks, the beacon slots have to be time-coordinated such that the beacon slots of the first network are completed before the beacon slots of the second network begin. The method includes transmitting a beacon frame having a beacon period switch information element which instructs the neighboring terminals in the first network of the need to merge, provides clock synchronization information; provides the time of the merge; and informs the neighboring terminals which beacon slot to occupy in the beacon period of the merged network. In order to deal with hidden terminals, the information needs to be forwarded terminal-to-terminal within each network.
