Abstract
An uplink power control technique may include a simplified maximum sector throughput (SMST) and a generalized maximum sector throughput (GMST). The SMST and GMST techniques may be used to determine a maximum sector throughput and cell-edge throughput to enhance the overall efficiency of the communication system. The uplink power control technique may determine the optimal uplink power value without collecting interference over thermal noise and without computing the individual channel losses in each neighboring sector.
Claims20
An apparatus, comprising:
- a transmitter coupled to a channel by an uplink, and
- a power management block coupled to the transmitter to determine an optimal uplink power value using a generalized maximum sector throughput (GMST) technique based on a signal to interference plus noise ratio target (SINRTarget), the optimal uplink power value to cause an optimal sector throughput and cell-edge throughput.
A method, comprising:
- determining a signal to interference plus noise ratio target (SINRTarget) according to a generalized maximum sector throughput (GMST) technique, the SINRTarget having a linear relationship with a carrier to interference plus noise ratio (CINRPreamble) of a downlink preamble;
- and
- determining an uplink power for a mobile node based on the SINRTarget, the uplink power to optimize sector throughput and cell-edge throughput for a home sector for the mobile node.
