Abstract
Methods and systems using information derived during a signaling period of a scheduling-based Medium Access Control protocol to adjust operation effective during data transmission periods. For example, channel estimation and transmission power adjustments are made based on indications provided by received signals.
Claims15
A method of adjusting operation of a wireless communication device operating in a scheduling-based transmission network, comprising:
- receiving a signal from another device during a scheduling period;
- determining an aspect of the received signal;
- and
- adjusting operation of the device during a data transmission period based on the aspect of the received signal.
A method for use by a wireless communication device to initialize channel estimates for data transmission periods in networks using scheduling-based access protocols;
- comprising:
- receiving a signal during a beacon period from another device;
- estimating a channel quality of a communication channel between the other device and the wireless communication device using the signal received during the beacon period;
- storing an indication of the estimate of the channel quality of the communication channel between the other device and the wireless communication device;
- receiving a preamble signal during a data transmission period from the other device;
- processing the preamble signal using the indication of the estimate of channel quality of the communication channel between the other device and the wireless communication device.
A method for use by a wireless communication device to determine a transmission rate for data transmitted by the wireless communication device, comprising:
- receiving a signal during a signaling period from another device;
- estimating a channel quality of a communication channel between the other device and the wireless communication device using the signal received during the signaling period;
- determining a transmission rate for data transmission from the wireless communication device to the other device during a data transmission period using the estimate of channel quality.
