Abstract: A base station configured to operate in accordance with a periodically repeated synchronization period is provided. The synchronization period comprises a plurality of successive pilot slots, the pilot slots being associated with groups of base stations in a one-to-one relationship. The base station is configured to be a member of a first group among the groups of base stations and to transmit, in each repetition of the synchronization period, one or more pilot signals in the pilot slot associated with the first group.

Abstract: The disclosure relates to a radio device, in particular a user equipment, for communication with a radio cell, the radio device comprising: a processor, configured: to generate a radio frame comprising a first data sequence and a second data sequence, to arrange the first data sequence within the radio frame in a time interval that is non-overlapping with respect to a predetermined time interval of a first data sequence of another radio device with another adjacent radio cell, and to apply an unequal power allocation for generating the first data sequence and the second data sequence.
