    摘要： An apparatus and method for UpLink (UL) radio resource allocation in a wideband wireless communication system are provided. In a method of operating a Relay Station (RS) for UpLink (UL) radio resource allocation in a wideband wireless communication system, the method includes relaying to a Base Station (BS) a resource request message of at least one or more Mobile Stations (MSs); receiving data from the at least one or more mobile stations; if the received data is non-real time traffic, queuing the data received from the mobile stations according to a traffic type; and requesting the base station to allocate necessary radio resources by checking a queue status. Accordingly, a delay can be reduced when the UL resource is allocated to an relay station for real time traffic.

    摘要： A communication method of a coordinator in a bidirectional event transmission sensor network comprising a sensor node and the coordinator is provided. The method includes sensing, in an uplink section, whether a signal having energy greater than or equal to a predetermined magnitude is received, the signal indicating occurrence of an uplink event detected by the sensor node, and transmitting, to the sensor node in a downlink section, a synchronization packet that is used for receiving the uplink event or for transmitting a downlink event in response to the coordinator detecting the downlink event or sensing the signal having energy greater than or equal to the predetermined magnitude in the uplink section. The bidirectional event transmission sensor network has a structure of a super frame that includes at least one standby slot (SS) including the uplink section and the downlink section.

    摘要： Provided are an ARQ apparatus and method for a multihop system in a broadband wireless access communication system. The ARQ method of a relay includes determining if the relay successfully receives specific data from a source and transmitting the specific data to a destination; receiving feedback data from the destination and determining if the destination successfully receives the specific data; generating feedback data including data indicating if the relay and the destination successfully receive the specific data, and outputting the feedback data to the source; and retransmitting the specific data, when the relay successfully receives the specific data but the destination fails to receive the specific data. Accordingly, when the MH-BTS successfully receives the data from the source but the destination fails to receive the data, the source does not retransmit same data to the MH-BTS.
