Various embodiments are described to address the need for providing wireless backhaul that may reduce operator startup costs while avoiding some of the drawbacks present in the prior art approaches. Generally expressed, the wireless network equipment (WNE) () of a collector cell provides access to a backhaul network () to one or more neighboring cells () via in-band wireless signaling. Given the frequency bands used by the collector cell WNE for communication with remote units, one portion of each band used for user traffic while another portion of each band is used for backhaul traffic. Having backhaul and user traffic share the assigned frequency bands can eliminate the need to license additional bands for wireless backhaul. Moreover, utilizing a portion of the existing, in-band orthogonal channels may be more spectrally efficient than using a separate radio in the same band.

The method operates in a wireless communication system serving a geographic area. The system includes first and second communication units within the geographic area which have first and second radio frequency (RF) channels associated therewith. The method includes defining a plurality of points within the geographic area; selecting an initial power of the first and second RF channels; identifying, at each of the plurality of points, a number of the first and second RF channels which are receivable; evaluating a system performance metric; adjusting the initial power of one of the first and second RF channels; based on the adjusted power re-identifying, at each of the plurality of points, a number of the first and second RF channels which are receivable; re-evaluating the system performance metric; based on the re-evaluation, accepting the adjusted power; and downloading the adjusted power to the wireless communication system.

Base stations (101, 102) utilize a spreading code that is dependent upon whether the particular base station (101) is operating in a synchronized, or an unsynchronized mode. Unsynchronized base stations (102) within the communication system (100) utilize a long code unique to the particular base station (102), and base stations (101) operating in a synchronized mode utilize a time shifted version of the same long code. To reduce the search time for remote units (113) within the communication system (100), a group identification code (GIC) (305) is broadcast during a time period that the long code is masked. The GIC (305) indicates a (spreading code) long code group to which the long code of each base station belongs. Additionally, each base station (101, 102) within the communication system (100) determines its synchronization status and utilizes a particular GIC (305) and long code based on the base station's synchronization status.

A data message transmission system for a cellular radiotelephone system is disclosed. Data to be transmitted is converted into a format compatible with radio transmission prior to transmission. The data is reconverted to its original format following reception. Handoff is accomplished by halting the data transmission prior to handoff and resuming data transmission after handoff. Call supervision occurs via busy-idle bit coding.

A simulator/controller (113) performs real-time simulation for system control in a code-division multiple access (CDMA) wireless communication system (100). The simulator/controller (113) simulates the effects of interfering AMPS wireless communication systems which coexist with CDMA wireless communication systems and also aids in the placement of new CDMA base-stations in the presence of existing AMPS base-stations. When system parameters are input to the simulator/controller (113), real-time simulation of the CDMA wireless communication system (100) predicts potential problem areas of the CDMA wireless communication system (100) and controls the CDMA wireless communication system (100) to avoid the problems before they occur.

Providing communications service to a coverage hole (22) in a DS-CDMA cellular communication system (50) involves an OMC (52) determining the transmitters (134-144) in adjacent cells (122-132) to the coverage hole (22). The OMC (52) places each of the transmitters (134-144) in the adjacent cells (122-132) in a power on demand mode (92). The OMC (52) then selects at least one, but less than all of the transmitters (134-144) to increase power to a pilot channel. The selected transmitter(s) is chosen base on one or more of the following factors, the transmitter's level of unused power, the interference level at the transmitter and the position of the transmitter.
