Abstract:
The present invention is directed to methods for adjusting a guard period in a cellular wireless communication system, to a base station adapted to adjust a guard period, and to a network management entity for adjusting a guard period. One method comprises the steps: obtaining (S1) an indication of at least one downlink frame for an interference measurement; transmitting (S2) during the at least one indicated downlink frame an interference signal; measuring (S3) interference at least during a part of the guard period succeeding the indicated downlink frame; and setting (S4) at least one of an end time of at least one subsequence.
