摘要： A novel protocol for an ad-hoc, peer-to-peer radio network that provides collision-free channel access with an emphasis on improving geographic reuse of the frequency spectrum. The protocol of the invention is executed on the reservation or control channel, and provides a method for allocating data transactions on the data channels. The system of the invention utilizes multiple parallel data channels that are coordinated by a single reservation channel. The transceiver of the system employs two modems to solve the channel reliability issues with multiple channel designs, where one is dedicated as a receive-only modem for gathering channel usage information on the reservation channel. High quality voice, video and data may be transmitted. The reservation channel implements a time division multiple access algorithm with dynamic slot allocation. In a distributed manner, nodes determine geographic reuse of slots based on channel quality extracted from the modem. Signal quality calculations are used to determine the likelihood of a slot reuse causing destructive interference within a node's neighborhood. Requests for slot usage are compared with the known traffic pattern and accepted or rejected by nodes within RF signal range based on the signal quality calculations.

摘要： Method and apparatus for reducing interference in a wireless communication system when the source of interference is a deterministic component of the system. In one embodiment, the receiver weights the transmitters according to when the source of interference is transmitted. Further, the transmitter may employ power boosting to overcome the source of interference. In one embodiment, a W-CDMA system transmits a sync channel concurrently with physical channels, wherein the sync channel is not orthogonal to the physical channels. The receiver may cancel the sync channel when receiving control or data information. Similarly, the receiver may weight the transmissions from multiple transmitters.

摘要： A method is disclosed for operating a wireless telecommunication system for providing a Multimedia Broadcast/Multicast Service MBMS broadcast transmission from a network operator (10) to a mobile station (100). A first step determines a minimum bit rate requirement to broadcast a MBMS message and a number of radio blocks per time period that are required to satisfy the bit rate requirement. A second step allocates the determined number of radio blocks in accordance with a multislot transmission technique, wherein a plurality of time slots are used per frame, such that the mobile station is provided with at least one idle radio block between two active MBMS transmission periods. The at least one idle radio block may occur between two active MBMS radio blocks. A third step transmits the determined radio block allocation to the mobile station. In the preferred embodiment the step of determining may include a consideration of radio channel conditions and a multislot class of the mobile station. In one embodiment the step of allocating attempts to maximize the number of idle radio blocks and the mobile station, during the idle radio block, performs at least one of entering a reduced power consumption mode of operation, or entering a neighbor channel measurement mode of operation. In another embodiment the step of allocating allocates radio blocks so as to complete the data transmission within the shortest period of time.

摘要： A method of encapsulating TDM data into individual data packets for transmission across a packet network includes delineating the TDM data into one or more signaling multiframes, wherein each signaling multiframe includes one period of a periodic signaling pattern. The method also includes appending a header that is associated with the individual data packets to each of the signaling multiframes of TDM data. Further, a method of selecting the number of multiframes of TDM data in the data packet includes calculating the efficiency of the data packet as a function of the number of multiframes, and selecting the number of multiframes so that the efficiency of the data packet increases exponentially as a number of time-slots in the TDM data increases.

摘要： In a communication system in which a plurality of communication terminals sequentially transfer data to a server during the respective transmission permissible periods assigned to the respective communication terminals, the communication terminal transfers a preamble for synchronization to the server at a time of starting the transmission permissible period, converts a data frame for every 8 bits into every 10 bit-code, and transmits to the server, the signal string with a code indicating the head added there, during the transmission permissible period, and turns a communication to the server into a zero signal state, during a period other than the transmission permissible period, while the server establishes a synchronization by reading the preamble for synchronization inserted into the signal string received from each of the communication terminals, converts a portion of the zero signal state of the signal string into a predetermined special code string, and inversely transforms the received signal string into the data frame before the coding.

摘要： Provided is a method of packet transmission capable of efficiently utilizing ACL link resources in transmitting and receiving packets after an ACL link is established in Bluetooth. A Bluetooth device A determines the maximum rate for packet size to be transmitted to a Bluetooth device B established in the link based on the ratio between a token rate A requested by the device A and a token rate B requested by the device B. When the token rate A is greater than the token rate B, the maximum rate N is set from the candidates of current time slot numbers occupiable as an ACL packet. When the token rate A is smaller than the token rate B, a rate is selected from the candidates of current time slot numbers occupiable as the ACL packet based on rate UnullNnulltoken rate A/token rate B.

摘要： A method and arrangement for automatic frequency correction in UTRA TDD mode, having a first stage (500) for frequency lock in idle mode, and a second stage (600) for receiving a channel estimate from beacon function (mx1), receiving a channel estimate from at least one other physical channel (mx2), and receiving output from a primary synchronisation code correlator (mx0, pc1, pc2), and for producing therefrom signals (X,Y,N) for use in frequency correction. By utilising first and second partial correlation values (pc1, pc2) which are balanced, DC offset effects may be substantially removed. This provides the following advantage of significantly improving performance at low levels of SNR, and removal of DC offset effects provides immunity to DC offsets arising from imperfections in hardware.

摘要： A base unit of a radio communication apparatus of the present invention includes a controller that discriminates whether or not company identifying information transmitted from a cordless handset is specific information in connecting a line in a Bluetooth (BT) communication mode, performs communication in another radio communication standard (company's own mode) on determining that the company identifying information is the specific information, and performs the communication in a BT standard on determining that the company identifying information is not the specific information, and a registering unit for registering an ID peculiar to the apparatus. This simple structure allows long-distance communication at higher sound quality with the other apparatus capable of performing CDL communication in the company's own mode using an error handling function, and sound communication at usual sound quality in a BT data format allowing short-distance communication even when the company identifying information is not the specific information.
