摘要： A method of implementing a fast dynamic channel allocation background interference reduction procedure in a wireless communication system includes a pre-code allocation process, a signal-independent code allocation process, and a post-code allocation process. The pre-code allocation process receives a timer trigger signal and retrieves system measurements from a centralized database. The physical resources to be reassigned are determined based on a figure of merit. The code allocation process checks the availability of a code set in the cell and generates timeslot sequences for the available timeslots. A code set is allocated to the available timeslots in a timeslot sequence, wherein a successful assignment is a solution. The interference signal code power (ISCP) is calculated for each solution and the solution having the lowest weighted ISCP is selected as an optimal solution. The reallocation information is stored in the centralized database and is sent in a physical channel reconfiguration request message.

摘要： A method of testing trunks grouped in tributaries to evaluate interoffice transmission quality across a TDM network of all trunks in the office. The method includes performing a testing cycle testing only one trunk in each tributary in the central office to verify transmission quality. Testing includes setting up an interoffice connection to the one trunk, performing a transmission test on the one trunk. The method can also include attempting a connection to every trunk in each tributary in the testing cycle. The method can also include performing a plurality of testing cycles until all trunks in the central office have been tested, wherein each testing cycle includes testing one untested trunk in each tributary.

摘要： A method for compressing data is provided that includes accumulating a plurality of bits associated with a communications flow and determining whether one or more of the bits correspond to a silence signal associated with a time division multiplexed (TDM) circuit that facilitates propagation of the flow. A predefined silence pattern may be communicated, in place of one or more of the bits, to a next destination when it is determined that one or more of the bits correspond to the silence signal.

摘要： A receiver (201) receives uplink transmissions (104) and passes the last N received frames (f1, f2, . . . , fN). The last N frames are analyzed and vector Bnull(b(f1), b(f2), . . . , b(fN)), is created. A dot product of B with all possible values of B (B1, B2, . . . , B9) is performed, and the transmission pattern from the last N frames is determined based on the dot product. Once the actual transmission pattern is known, the next received frame type is predicted. If the next frame (Nnull1) is predicted to be a DTX frame, then a threshold is adjusted to make the DTX_VS_ERASED threshold comparison more likely to conclude that frame Nnull1 was a DTX. Similarly, if the next frame is predicted to be a voice frame, then the threshold is adjusted to make the DTX_VS_ERASED threshold comparison more likely to conclude that the frame was voice frame.

摘要： A radio communication device which manages a network defines a predetermined transmission frame cycle, allocates in the frame specific access slots as timing with which the individual radio communication devices in the network concerned receive a transmission, puts the information of the allocation in a beacon signal, and transmits the signal. Each radio communication device performs receiving operation at access slots specific to the device itself defined by the beacon signal. When information transmission is made between arbitrary communication devices in the network, access slots for the device which is to receive the information are used.

摘要： In this method of managing packet transmission by a mobile, a forward control channel that includes scheduling information and acknowledgement information is transmitted. The scheduling information schedules transmission by a mobile and the acknowledgement information indicates successful or unsuccessful receipt of at least one packet sent by the mobile. A mobile then determines whether to transmit based on the scheduling information and determines whether to transmit a new packet or retransmit a previously sent packet based on the acknowledgement information.

摘要： An improved modulation circuit and method for TDMA are provided, wherein the transmission data TD in odd-numbered time-slots are processed based on the transmission-window signal TWe with a differential encoder 10o, a timing generator 20o, a filter 30o, an amplitude data generator 40o, a multiplier 50o and an I/Q-discriminator 60o, which are configured as odd-dedicated units, and is output from an adder 71 as transmission signal data IT and QT. The transmission data TD in even-numbered time-slots is processed with a differential encoder 10e and other components, which are configured as even-dedicated units, and is output from the adder 71 in common. Thereby, the appropriate data transmission can be achieved in spite of the decrease of guard bits between a couple of time-slots.

摘要： A wireless network, including a plurality of network elements such as a wireless access point (9), and computer stations (2, 4, 6), is disclosed. The wireless network operates so that each network element (2, 4, 6, 9) waits for a pseudo-randomly selected duration, after the end of a frame on the channel, before initiating transmission. One of the network elements, such as the wireless access point (9), measures the performance of the network over a measurement period (T), and adjusts a minimum value of the upper limit of the range from which the random duration is selected, according to the performance of the network over the measurement period. The times measured may be the successful transmission time (Ts), which is maximized in adjusting the minimum value, or the idle and collision times (T1,Tc), which are equated in the optimization of the minimum value.
