Abstract: A method for reporting a channel status in a mobile communication system including a relay station (RS) is provided. When a mobile terminal in the coverage of a base station (BS) receives a service through an RS, the RS reports a channel status between the RS and the terminal to the BS to allow the BS to decide whether or not to communicate with the terminal through the RS. In the method, a first RS in communication with a BS and at least one terminal measures a channel quality with a first terminal, compares the measured channel quality with a threshold and transmits a report message to the BS according to the comparison. The report message requests the BS to measure channel quality of at least a second RS or the first terminal in communication with the BS.

Abstract: To reduce the process of a cell search including sector identification without increasing loads on a transmission/reception apparatus. A synchronization channel (SCH) included on downlink in a multicarrier mobile communication system is multiplied by a sector specific code and a cell specific code (step S1), assigned to subcarriers on the frequency axis (step S2), subjected to spreading processing and IFFT processing (steps S3, S4), and further subjected to insertion of GI and D/A conversion processing (steps S5, S6), and multicarrier is transmitted from a directional antenna of each sector (step S7). The receiving side specifies a SCH position by auto-correlation method or cross-correlation method, performs FFT, and then, concurrently performs identification of a sector by detection of the sector specific code, and acquisition of cell specific information by demodulation of the cell specific code.

Abstract: A method for communication includes allocating, in a multiple-access communication system (20) that uses multiple subcarriers, first subcarriers to a first communication terminal for transmitting first data, and second subcarriers to a second communication terminal for transmitting second data. The first communication terminal is assigned to modulate the first data onto at least some of the first subcarriers using a first multi-carrier modulation scheme, to produce a first signal. The second communication terminal is assigned to modulate the second data onto at least some of the second subcarriers using a second multi-carrier modulation scheme, which has a reduced peak-to-average power ratio (PAPR) relative to the first multi-carrier modulation scheme, to produce a second signal. Simultaneous communication is carried out with the first and second communication terminals by simultaneously receiving the first and second signals over the first and second subcarriers.

Abstract: Multiple redundant sources for a datastream can be established in a network, where the redundant sources are configured with the same source address. One of the redundant sources provides the datastream to a receiver of a multicast group. If the redundant source fails, another redundant source can be used in its place, ensuring the receiver continues to receive the datastream. A routing element coupled to a redundant source monitors the redundant source for failure and informs the rest of the network of the status of the coupled redundant source. The routing element can inform other routing elements of the status by advertising or withdrawing a route that reaches the coupled redundant source, which the other routing elements can use to update their routing tables.

Abstract: A method for formatting a signal in a mobile communication system by appending a plurality of medium access control headers to a plurality of medium access control-service data units for data transfer between a mobile station and network in the mobile communication system. If the service data units have the same characteristics, a medium access control-protocol data unit is formed by successively coupling the service data units to any one of the medium access control headers. If the service data units have different characteristics, the protocol data unit is formed by sequentially coupling each of the service data units and each of the medium access control headers. The formed protocol data unit is then transformed into a transport block with a predetermined size.

Abstract: A communications network is provided for a water treatment system. A controller is in communication with a plurality of network elements using digital communications. The network elements have a connection configured to connect the network element to the controller or another network element. The controller sends a message to the network elements to configure the network elements for communication with the controller. The controller receives a response from the network elements including a network address and a header. If the network address is a default address, configuration information is sent to the network element for communication on the network. If the network address is not a default address, communication is established with the network element. Messages sent from the controller to a network element having a network address not matching the network address of the network element are sent over the network to a next network element.

Abstract: A remote enclosure houses multiple subsystems. A first subsystem is coupled to a central office over a high-speed communication channel such as an OC-3 channel. The first subsystem extracts a downstream message from a first embedded operations channel included in the high-speed communication channel. The first subsystem also, when the downstream message is targeted to a first unit included in the first subsystem, forwards the message to a unit that processes the message for the first unit. When the message is not targeted to any unit included in the first subsystem, the first subsystem forwards the downstream message to another subsystem housed within the remote enclosure via a second embedded operations channel included in a second communication channel. The second subsystem is subtended from the first subsystem and is connected thereto by the second communication channel.
