Reduction of Power Consumption in Wireless Communication Terminals
First Claim
1. A method for decreasing power consumption in a wireless communication terminal, the method comprising the steps of:
- selecting at least one communication device as a communicating peer in a wireless communication system;
measuring a signal quality variable from at least one of the at least one communication device selected in the selecting step, each signal quality variable being measured based on a signal received from a respective one of the at least one communication device selected in the selecting step, whereby at least one signal quality variable is obtained;
adjusting receiver performance based on at least one of the at least one signal quality variable obtained in the measuring step, the adjusting step being performed for reducing power consumption while ensuring reception of respective signals from the at least one communication device selected in the selecting step;
monitoring if the wireless communication terminal'"'"'s own transmission is approaching; and
readjusting receiver performance for determining availability of a common air medium at a performance level enabling detection of transmitting communication devices within a coverage area of said own transmission, the readjusting step being performed when the monitoring step indicates that said own transmission is approaching.

Abstract
The invention relates to a mechanism for decreasing power consumption in a wireless terminal intended for a communication system where availability of a common air medium is to be determined by the terminal prior to transmission. The terminal selects at least one communication device as a communicating peer and adjusts receiver performance based on received signal strength and optionally other parameters measured from at least one of the at least one wireless communication device, the receiver performance being adjusted for listening to the at least one wireless communication device with reduced power consumption. The terminal further generates an indication when its own transmission is approaching and readjusts the receiver performance for determining the availability of the common air medium at a performance level enabling detection of devices that may be disturbed by said own transmission.

30. A wireless communication terminal for a wireless communication system, the wireless communication terminal comprising:
-
selection means for selecting at least one communication device as a communicating peer in the communication system; first measurement means for measuring a signal quality variable from at least one of the at least one communication device, each signal quality variable being measured based on a signal received from a respective one of the at least one communication device, whereby at least one signal quality variable is obtained; first performance control means for adjusting receiver performance based on at least one of the at least one signal quality variable, thereby to permit the wireless communication terminal to receive respective signals from the at least one communication device with reduced power consumption; monitoring means for monitoring if the wireless communication terminal'"'"'s own transmission is approaching; and second performance control means for adjusting receiver performance to a performance level enabling the terminal to detect transmitting communication devices within a coverage area of said own transmission, the second performance control means being configured to operate when the monitoring means indicate that said own transmission is approaching. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)

44. A computer useable medium having computer readable program code embodied therein to control a wireless communication terminal, the computer readable program code comprising:
-
a first computer readable program code portion for causing at least one communication device to be selected as a communicating peer for the wireless communication terminal; a second computer readable program code portion for causing the wireless communication terminal to adjust receiver performance based on a signal quality variable measured based on a signal received from at least one of the at least one wireless communication device; a third computer readable program code portion for causing the wireless communication terminal to generate an indication when the wireless communication terminal'"'"'s own transmission is approaching; and a fourth computer readable program code portion for causing the wireless communication terminal to adjust receiver performance to a level enabling the wireless communication terminal to detect transmitting communication devices within a coverage area of said own transmission, the fourth computer readable program code portion operating in response to the indication.
