Abstract: PROBLEM TO BE SOLVED: To attain more effective use of resources of a radio communication system by operating a radio unit in a macro diversity mode and on the basis of an operation category of the radio unit related to the mobility of the radio unit. SOLUTION: In a fixed operation category, a radio unit 40 can be firmly fixed the directly antenna of which has the considerably large gain and helps receiving. As the position of the antenna is already known, the macro diversity/ handoff mode, i.e., the operation of the unit 40 can be established and set in an installation/high frequency optimization mode by adjusting the position or direction of the antenna. Thus, in a limited category, the unit 40 can operate in a macro diversity mode, i.e., an operation mode different from the mode that is used for a fixed radio unit.

Abstract: PROBLEM TO BE SOLVED: To reduce all interference between wireless terminals by allocating codes to plural wireless terminals based on decided plural channel characteristics. SOLUTION: A combined signal is transmitted to a simultaneous channel estimator 114 and a space-time matched filter 116. The simultaneous channel estimator 114 receives a base band signal and decides characteristics κpk of a wireless channel where the signal is received. A base station 102 has a code optimizer 118 for allocating a code to a wireless terminal. A processing set is initialized with respect to one of the wireless terminals. A target wireless terminal is selected from the processing set. When there is only one wireless terminal in the processing set, the wireless terminal is selected as the target wireless terminal. Regarding the wireless terminal selected as the target, random code search is executed.

Abstract: PROBLEM TO BE SOLVED: To surely and easily recover transfer of a signal by setting a plurality of paths explicitly instructed between a source and a receiver side router and allowing the receiver side router to select one of the paths instructed explicitly as a primary path, to make communication along the selected path and to immediately select a secondary path as a new primary path on the occurrence of a fault in the primary path. SOLUTION: A node S makes communication to a node E by using a plurality of explicit label switching path indication paths in existence between the nodes S and E. Using a label distribution protocol can assist setting of a label switching path LSP on the basis of a restriction condition of the explicit path instruction. The restriction condition of an explicit path instruction provides an inter-termination setup device with a method that uses a label distribution protocol of the LSP with an instructed path on the basis of a restriction condition started by an input LSR top reserve a resource. A plurality of the explicit path instruction label switching path is set between the router LSRS and an LSRE.

Abstract: PROBLEM TO BE SOLVED: To protect from a fault in an electric communication exchange by generating a check bit to a sub-set of each of data, adding the check bit to a sub signal and selecting one sub signal from the sub signals resulting from routing two incremented sub signals in parallel through duplicate components of a distributed switching fabric. SOLUTION: Corresponding duplicate switch elements 302 in pairs in a switching fabric process the two same versions of incremented sub signals as a result in parallel. The sub signals in pair that are routed as a result are fed to a corresponding fault detector 308. The fault detector 308 applies the same check sum function as being used by a check bit generator 306 to one or both subset data of the sub signals that are routed depending on realization.

Abstract: PROBLEM TO BE SOLVED: To shorten the time for retransmitting an error information block (e.g. deteriorated frame) and to improve the throughput of a communication channel where information is transported by applying a data puncture operation to information transmitted by a communication system, based on information on a received signal. SOLUTION: A receiver 109 of a user device 106 receives an information block via a forward link 102. Feedback or error restoration data extracted by a processor 111 is contained in the received information block and it is decided whether previous information transmitted by the user device 106 is to be retransmitted. The user device 106 transmits appropriate decoding status data to information which is transmitted at present and time, when the information block is retransmitted is reduced. The insertion of decoding status data into transmitted information is called data puncture.

Abstract: PROBLEM TO BE SOLVED: To efficiently perform an automatic repetition request by making an identification number correspond to at least one unit of data to be transmitted. SOLUTION: On a receiver side, variables V(N) and V(R) are monitored. The variable V(N) shows a maximum sequence number, by which all the bytes of previous data are received without errors. V(R) shows the sequence number of subsequently new data byte, which is expected to be received from a transmitter. A variable VT(N) is a value of V(N), which is received the latest from the receiver in a control message sent from the receiver to the transmitter. A variable VT(R) is the latest value of the variable V(R) transmitted to the transmitter from the receiver in the control message. The variable V(S) is the sequence number allocated to the byte of next data, which is to be transmitted to the receiver from the transmitter.

Abstract: PROBLEM TO BE SOLVED: To provide a power control system for a cellular communication system which can appropriately control transmitter power, so that do not occur by controlling the transmission power of a wireless transmitter in relation to the number N of ACK expected for radio transmission via a wireless link. SOLUTION: A wireless unit 12 is connected to a wireless network 18 by using a wireless MODEM(WM). The WM transits a radio packet and detects ACK (affirmation response) from an access point(AP) 24. A power control system is constituted in the wireless unit 12. The power control system decides a packet loss rate(PLR) as the number of lost ACK/the number of expected ACK for the WM. When the PLR is larger than a first threshold, the power control system increases the transmission power of the wireless unit 12. When the PLR is smaller than a second threshold, transmission power is reduced.

Abstract: PROBLEM TO BE SOLVED: To provide a process for extrusion-molding a graded refractive index plastic optical fiber and an apparatus therefor. SOLUTION: This extrusion molding process has a step of introducing a polymer material for a first core into a first nozzle and a step of introducing a polymer material for a second clad into a second nozzle. At least one polymer material has a dopant having a refractive index for changing the refractive index of the polymer material. The nozzles are concentrically arranged. The first nozzle exists within the second nozzle. When the materials are introduced into a diffusion part 22, the materials simultaneously flow concentrically and the diffusion of the dopant is embodied between the first material and the second material and eventually the graded refractive indices are embodied. The first and second polymer materials move continuously through the diffusion part 22 and flows through an outlet side die and are then drawn out as a fiber.
