Method for controlling power level based on packet error rate in wireless personal area network system
First Claim
1. A method for controlling a power level based on a packet error rate (PER) in a wireless personal area network (WPAN) system, the method comprising the steps of:
- a) at a receiver, computing a PER of a packet in an initial check duration of PER (DP) wherein a transmission power level of the packet is set by a piconet coordinator (PNC);
b) at the receiver, determining whether the computed PER satisfies a target PER, adjusting a target signal-to-interference ratio (SIR) and requesting a transmitter to adjust the initial transmission power level; and
c) at the receiver, determining whether the number (N) of successive G is larger than a power control threshold, wherein G denotes DP satisfying the target PER, changing the target SIR based on the determination result whether the number (N) of successive G is larger than the power control threshold, and requesting the transmitter to adjust the possible transmission power level.

Abstract
Disclosed is a method for controlling a power level based on a packet error rate (PER) in a wireless personal area network (WPAN) system. The method for controlling a power level based on a packet error rate (PER) in a wireless personal area network (WPAN) system, includes the steps of: a) at a receiver, computing a PER of a packet in an initial check duration of PER (DP) wherein a transmission power level of the packet is set by a piconet coordinator (PNC); b) at the receiver, determining whether the computed PER satisfies a target PER, adjusting a target signal-to-interference ratio (SIR) and requesting a transmitter to adjust the initial transmission power level; and c) at the receiver, determining whether the number (N) of successive G is larger than a power control threshold, wherein G denotes DP satisfying the target PER, changing the target SIR based on the determination result whether the number (N) of successive G is larger than the power control threshold, and requesting the transmitter to adjust the possible transmission power level.

6. A method for controlling a power level based on a packet error rate (PER) in a wireless personal area network (WPAN) system, the method comprising the steps of:
-
a) at a transmitter, transmitting a packet in a check duration of the PER (DP), wherein a transmission power level is set by a piconet coordinator (PNC), and then computing the PER based on an immediate response (immediate Ack); b) at the transmitter, determining whether the computed PER of the packet satisfies a target PER, and adjusting the transmission power level, and setting an initial transmission power level; and c) at the transmitter, determining whether the number (N) of successive G is larger than a power control threshold (M), wherein G denotes DP satisfying the target PER, adjusting the transmission power level based on the determination result whether the number (N) of successive G is larger than a power control threshold (M), and optimizing the transmission power level. - View Dependent Claims (10)
