Abstract
Slave units of a mobile communication system each determine (S), out of a predefined sliding codebook of Q unique radio frame configurations, a radio frame configuration for communicating with user equipments, and transmit (S), to a master unit of a cluster which the slave units belong to, a request to use the determined radio frame configuration. The predefined sliding codebook comprises sub-codebooks each grouping together radio frame configurations of the Q unique radio frame configurations, that share the same downlink-to-uplink subframe ratio but with a phase offset of the radio frame configurations. The master unit identifies (S) a common sub-codebook out of the sub-codebooks of the predefined sliding codebook, that comprises most of the determined radio frame configurations indicated in the requests received from the slave units, and, for each of the determined radio frame configurations, selects (S, S, S, S) a radio frame configuration out of the Q unique radio frame configurations, that corresponds to a sub-codebook of the determined radio frame configuration and minimizes an average misalignment with a radio frame configuration of the common sub-codebook.
