Patent ID: 11743946

Abstract:
The present disclosure relates to methods and arrangements for dynamically configuring repeated transmission of random access response messages from an access node, wherein the random access response message is repeatedly transmitted in response to receipt of a random access request from wireless device operating in a coverage enhancement, CE, mode and wherein the random access response message is configured for repeated transmission on a downlink channel using a repetition level selected from a set of repetition levels associated with a CE level of the CE mode. The repetition level represents a predetermined number of repeated transmissions and the CE level represents a group of wireless devices with similar radio conditions. The method comprises determining, for a predetermined data set, a ratio of successful to initiated random access attempts when applying a selected repetition level of the set of repetition levels for repeated transmission of the random access response messages on the downlink channel, wherein a random access attempt is counted as successful responsive to receipt of a first uplink transmission on a packet uplink shared channel, PUSCH. The method further comprises selecting an operational repetition level of the set of repetition levels for repeated transmission of random access response messages on the downlink channel based on the determined ratio.
