摘要： 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.

摘要： 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 each of at least a subset of the multiple carriers, and a reconfigurable bus interconnecting the channel unit boards and radio boards. The base stations 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 to Transmit Diversity (QTD), Multi-Carrier (MC) cdma2009, 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 fixed connections between the bus signal lines and appropriate ports of the channel unit and radio boards.

摘要： Disclosed is an interface and method for data transmission between digital and radio frequency (RF) components of a base station. The interface and method involves transmitting transmit or receive data over a first set of time slots and transmitting various uplink or downlink low rate static/control signals over a second set of time slots. The transmit data includes in-phase transmit data bits and quadrature phase transmit bits, and the receive data includes in-phase transmit data bits and quadrature phase transmit bits received over a diversity antenna system.
