PROBLEM TO BE SOLVED: To solve a problem in which: larger aggregations are intended to be used for large messages, and/or small messages when a lower code rate is required, for example under bad channel conditions; but restricting search spaces to reduce processing complexity limits availability of suitable aggregations for radio channel conditions that are different as the radio channel conditions vary.SOLUTION: The present invention relates to a method for communicating between a primary station and at least one secondary station, comprising configuring a secondary station being in a first state to search at least one of a plurality of search spaces having a first structure, the first structure consisting of at least a first number of resource sets having a first size, where at least one resource set is used to transmit a message to the considered secondary station, changing the search space structure to a second structure different from the first structure when the secondary station enters a second state. |
