1. A method for use in synchronization and channel estimation, the method comprising:
- generating a synchronization reference sequence for synchronization of two communication endpoints and for estimation of characteristics of a communication channel;
determining a maximum repetition interval of said synchronization reference sequence based on constancy of said characteristics of said communication channel; and
transmitting said synchronization reference sequence with a repetition interval equal to or less than said maximum repetition interval.

Abstract
Measures for synchronization and channel estimation in local area communication scenarios. Such measures may for example comprise generating a synchronization reference sequence for synchronization of two communication endpoints and for estimation of characteristics of a communication channel, determining a maximum repetition interval of the synchronization reference sequence based on constancy of the characteristics of the communication channel, and transmitting the synchronization reference sequence with a repetition interval equal to or less than the maximum repetition interval.
