Abstract: PROBLEM TO BE SOLVED: To provide a system that can dynamically decide a cell coverage in a wireless communication system. SOLUTION: The system to decide the coverage in the wireless communication system uses location information as to a wireless unit to collect information relating to communication between the wireless unit and the wireless communication system in cross-reference with the location information. The wireless communication system decides and/or receives the location information with respect to the wireless unit with other information related to the location information. The information for every location can be used to represent the coverage for a geographical area. For example, in the communication between a serving base station and the wireless unit, the serving base station receives and/or decides a signal quality measurement value of a forward link and/or reverse link in a specific location.

Abstract: PROBLEM TO BE SOLVED: To produce an analog signal for transmission by converting a digital signal into analog format, providing an analog signal at a transmission fre quency using an analog signal image produced by a DA converter(DAC), and using the projected analog signal image. SOLUTION: A digital transmitter produces an analog signal at a desired frequency, using the analog signal image from the DAC. By setting or adjusting the conversion rate for the DAC or the digital signal frequency, the analog signal image produced from the DAC can be positioned in the desired frequency band. When the digital signal is converted into analog format, the DAC produces an analog signal image repeated at integral multiples of half the conversion rate, so that the analog signal image can be produced at an appropriate frequency band suitable for amplification and transmission.

Abstract: A system for determining coverage in a wireless communications systems uses location information for a wireless unit and collects information on communications between the wireless unit and the wireless communications system in association with the location information. The wireless communications system determines and/or receives location information for the wireless unit along with other information associated with the location information. The information by location can be used to represent the coverage of a geographic region. For example, during communications between a serving base station and a wireless unit, the serving base station could receive and/or determine signal quality measurements of a forward link and/or of a reverse link at a particular location. Additionally, neighboring base stations can monitor the communications and determine and/or receive location information for the location of the wireless unit along with the information associated with or corresponding to the location of the wireless unit. The associated information can be linked with additional parameters, such as wireless unit type, wireless unit identity, frequency, operating conditions and/or base station identity. In accordance with other aspects of the present invention, the information and/or measurements stored by location can be used to derive additional and/or different information by location or determine how the wireless communications system communicates with a wireless unit at a location, for example the base station to service the wireless unit at the location. A wireless unit in a location or range of location(s) could be served by a serving base station(s) at a certain transmit power and frequencies given certain operating conditions or parameters, such as time, weather, traffic load, path loss and/or interference level. A change in operating condition could trigger a dynamic change in the RF coverage provided by the serving base station(s) and/or neighboring base stations to the wireless unit(s) in the location or range of locations.

Abstract: A digital transmitter converts a digital signal into analog form with a digital to analog converter (DAC) and uses an analog signal image produced from the DAC to provide an analog signal at a transmission frequency and/or uses a projected analog signal image to produce analog signals for transmission. Rather than removin g analog signal images with a low pass filter at the output of the DAC and/or using analog signal images and analog mixers for frequency conversion, the digital transmitter uses the analog signal images from the DAC to produce the analog signals at the desired frequency/frequencies. By setting and/or adjusting the conversion rate for the DAC and/or the digital signal frequency/frequencies; the analog sign al images produced from the DAC can be positioned in the desired frequency band(s). Fo r example, the digital transmitter can position the digital signals within non - overlapping portions of a conversion bandwidth defined as one-half the conversion rate f or the DAC. When the digital signals are converted into analog form, the DAC produc es analog signal images periodically repeated at multiples of one-half the conversion rate such that analog signal images are produced at the appropriate frequency band(s) for amplification and transmission.
