Abstract
Official abstract text for this publication.
In a method for communication by radio afrequency band that is subdivided into a plurality of subbands is used. Subbands are occupied by radio stations for sending signals. Before sending a signal, a radio station carries out a filtering operation by using a filter function and sends the signal on at least one subband. A parameter of the filter function depends on the occupation of at least one subband adjacent to the at least one subband.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for communication by radio, comprising: subdividing a frequency band into a plurality of subbands; allocating a first subband to a first user station for transmitting signals with a base station; receiving scheduling information at the first user station from the base station concerning the frequency allocated to a second user station; and filtering signals at the first user station prior to transmitting the signals from the first user s…
