Abstract
Official abstract text for this publication.
A probe, listen and select (PLS) technique can be used to select from an available frequency spectrum a frequency band whose communication quality is suitable for wireless communication at a desired rate. Probe packets can be transmitted on different frequencies ( 223 ) during a known period of time (T PLS ), and frequency channel quality information can be obtained ( 225 ) from the probe packets. This quality information can then be used to select a desirable frequency band ( 227 ). The communication quality of the selected band can also be used as basis for selecting ( 141 ) from among a plurality of modulation and coding combinations that are available for use in communications operations.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of selecting a frequency band, comprising: communicating a plurality of signals encoded in a first mode at different respective times on a respective plurality of frequencies within a frequency bandwidth; obtaining information indicative of channel quality associated with the communicated plurality of frequencies; communicating signals in a second mode in response to said obtained information on at least one frequency of the plurality of frequen…
