Filter arrangement dependent on occupation of an adjacent band

摘要

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.

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 station using at least the first subband, the first user station filtering using a filter function having a parameter that depends on whether a second subband is allocated to the second user station, the second subband being directly adjacent to the first subband the first user station transmitting the signals using at least the first subband after filtering, wherein the first user station filters such that the first user station itself modifies and adapts the frequency allocation of the first subband depending on the second user station's second subband allocation.
