摘要： A method and system for wireless communication in which a plurality of media access control (“MAC”) packet data units (“PDUs”) corresponding to a plurality of wireless communication connections are received. The plurality of MAC PDUs is grouped into a relay packet and the relay packet is transmitted. Such grouping and transmission of the relay packet is performed by one or more relay nodes. The traffic control for the transmission can also be based on centralized or decentralized routing control and/or centralized or decentralized QoS control.

摘要： A wireless network includes a base station and a relay station for extending wireless coverage of the base station. Downlink data is sent by the base station and relayed through the relay station to a mobile station, where the downlink data is associated with a preamble that is sent directly from the base station to the mobile station. A transmit power of the relay station is adjusted for transmitting the downlink data from the relay station to the mobile station to reduce a difference between a first power level of the preamble received at the mobile station and a second power level of the downlink data received at the mobile station. The uplink transmit power of the mobile station for the data sent to the relay station is adjusted to compensate for the difference in path loss from mobile station to base station and mobile station to relay station and to compensate for the difference in noise_plus_interference level at relay station compared to that of the base station.

摘要： A radio system employing Orthogonal Frequency Division Multiplexed (OFDM) includes a Base Transceiver Station (BTS) along with a number of mobile terminals located within a coverage area of the BTS. In this system, a target mobile terminal is provided with a focused transmission beam to receive high data rate traffic information while the remainder of the mobile terminals are provided with pilot and signalling information. To achieve both objectives, a BTS is implemented with a transmission apparatus that generates a directional transmission beam for the data traffic information. In one design, this directional beam transmits the pilot and signalling information along with the data traffic information by rotating the beam within the coverage area. In another design, the BTS has a transmission apparatus that generates more than one transmission beam. In one case, the BTS transmits a directional transmission beam for the data traffic information required by the target mobile terminal and a second broad transmission beam for the pilot and signalling information required by the all of the mobile terminals. In another case, the BTS transmits two directional transmissions beams, one beam for data traffic information and one rotating beam for pilot and signalling information.

摘要： Devices and methods are provided for managing device-to-device (D2D) communications session in a wireless-enabled communication environment. A first client node comprises a database containing location and ID information associated with a plurality of second client nodes. The location information in the database is updated as individual second client nodes change their location. As the location information is updated, it is processed by the first client node to determine the distance between it and an individual second client node. If the distance between the first client node and the individual second client node is within a viable D2D communications range, then the user of the first client node is notified that a D2D communications session can be initiate with the individual second client node.

摘要： A communication network (100) includes a two-way communication system (101) having a number of base stations (102-108) providing corresponding coverage areas (110-116) for one or more mobile terminals (148 and 150). In order to minimize congestion of the two-way communication system (101) a broadcast system (118) is included which allows for messages to be transmitted to the mobile terminals (148 and 150). Provision of such a broadcast system frees-up network resources that would otherwise be required to support the transmission of such messages. In one embodiment, the communication network (100) includes a number of information gathering devices such as traffic cameras (126-136) that collect information on traffic conditions within the communication network (100). By determining the location of the mobile terminals (148 and 150) and their intended journey routes, or based upon travel information previously provided to the network, the communication network (100) can transmit via the broadcast system (118) images of traffic conditions along one or more particular travel routes to the mobile terminals (148 and 150). The mobile terminals (148 and 150) include receiver sections for receiving both the messages transmitted by the two-way communication system (101) and the one-way broadcast system (118).
