Abstract
A method for setting a power control level (600) in a wireless communication system. The method includes the steps of obtaining (620) transmission information from a wireless subscriber unit, and modifying a power control level and/or a communication channel format (660) in response to said transmission information. Preferably, the transmission information is re-transmission requests from a wireless subscriber unit, which are transmitted frequently. In this manner, rapid adjustment of power control can be attained utilising an optimal selection of the available communication channel format, followed by a fine-tuning power control operation.
Claims33
A method for setting a power control level in a wireless communication system, the method comprising the steps of:
- obtaining transmission information from a wireless subscriber unit;
- modifying a power control level in response to said transmission information;
- and
- modifying a communication channel format in response to said transmission information.
A method for selecting a transport format to transmit messages in a wireless communication system, the method comprising the steps of:
- obtaining transmission information from a wireless subscriber unit;
- and
- modifying a communication channel format in response to said transmission information.
A method for setting a power control level, the method comprising the step of:
- extracting a portion of a power control signal;
- using said portion of a power control signal to determine a signal quality granularity adjustment to transmit a signal in accordance with a number of communication channel formats;
- and
- selecting a downlink transmission rate or power control level in response to said determined signal quality granularity.
A radio network controller comprising:
- means for obtaining measurement report data from a wireless subscriber unit;
- means for determining a downlink transmission rate or power control level based on said measurement report data;
- and
- means for modifying a downlink transmission rate or power control level in response to said measurement report data by modifying a communication channel format.
