Abstract: A wireless communication system base station includes a number of channel unit boards, each including multiple channel elements for providing processing operations for signals assigned to multiple carriers of the system. A given channel unit board includes a multiplexer which is operative to implement multi-carrier/multi-sector channel pooling by assigning a given one of the channel elements of that board to any one of the multiple carriers of the system. For example, the multiplexer in the given channel board may be operative to connect the channel elements of that board to I/Q signal buses associated with different system carriers. The I/Q signal bus for each of the carriers is then combined on the given board with corresponding signals from other boards. The invention allows each of N channel elements of the given channel unit board to be assigned to a particular one of up to N carriers of the system, thereby providing substantially improved flexibility in terms of system configuration.

Abstract: A wideband code division multiple access (CDMA) communication system overlayed on an IS-95 network generates two or more digital bit streams from a group of wideband digital data streams, each digital bit stream spread to form a CDMA component signal. Each CDMA component signal is combined with a corresponding IS-95 digital bit stream to form a composite CDMA signal, allowing a base station to share transmitter subsystems between the wideband and IS-95 systems. For up to three carrier frequencies, up to three composite CDMA signals are employed. A digital bit stream for a group of summed user conversations in the IS-95 system modulates a respective RF carrier frequency to generate a low-power RF signal. The CDMA component signals of the wideband CDMA system are generated so each has a chip rate identical to the chip rate of the digital bit streams of the IS-95 system. The baseband digital data streams for all wideband user conversations are summed digitally for each targeted RF carrier frequency to produce the composite wideband digital signal for each targeted frequency. In one application, each composite wideband digital signal, each at the IS-95 chip rate, is then used to modulate a carrier frequency which is either the same, or has approximately the same frequency and phase as the carrier frequency used in the IS-95 system. Three low-power RF signals are produced in the wideband system, each having the same spectral characteristics as the corresponding low-power RF signals generated in the IS-95 system. These low-power RF signals at the same frequency are combined into a single signal provided to the amplifier and antenna subsystem of a base station transmitter. In another application, each composite digital signal is digitally combined with a respective IS-95 digital bit stream prior to modulation by respective RF carrier. Therefore, signal combining between the IS-95 and wideband CDMA portions of a base station system is accomplished either digitally or with RF signals prior to amplification, thereby allowing the IS-95 system and wideband CDMA system portions of the base station to share RF filters, amplifiers and antennas of the base station transmitters.

Abstract: A reconfigurable base station suitable for supporting multiple wireless communication system standards includes a set of channel unit boards, each providing processing operations for user signals assigned to multiple carriers of the system, a set of a radio boards, each generating a radio frequency (RF) output signal for eac h of at least a subset of the multiple Garners, and a reconfigurable bus interconnecting the channel unit boards and radio boards. The base station is configured to support a particular wireless system standard, such as IS-95 CDMA, by assigning particular user signals to designated signal lines of the reconfigurable bus. The base station may then be reconfigured to support other CDMA standards, such as, e.g., IS-95C with or without Orthogonal Transmit Diversity (OTD), Multi-Carrier (MC) cdma2000, or Universal Mobile Telecommunications System (UMTS), by assigning other user signals to the signal lines of the reconfigurable bus. The assignment of signal lines may be implemented dynamically under the control of software running on a base station control computer, or by establishing fixe d connection between the bus signal lines and appropriate ports of the channel unit and radio boards.

Abstract: A method and apparatus for guaranteeing packet delivery times in an asynchronous network includes generating a global timing schedule to synchronize the communication between the terminals of a network and, in response to at least one trigger, transmitting and receiving data according to the generated global timing schedule. To optimize bandwidth utilization, more than one terminal may transmit data during a specific time slot of each time frame of the global timing schedule as long as no more than one terminal attempts to transmit data to a common other terminal.

Abstract: A single base station supports the non-diversity transmission of a first digital signal type and the diversity transmission of a second digital signal type. The base station includes primary channel boards for modulating and encoding a first digital signal type and secondary channel boards for modulating and encoding a second digital signal type. A first group of transmit radio modules accept the first digital signal type and the second digital signal type and provides a composite electromagnetic output signal. Each transmit radio module is associated with a different sector. A second group of transmit radio modules accept the second digital signal type from secondary channel boards and provide a diverse electromagnetic output signal for complementing the composite electromagnetic output signal.
