CPC H04W 74/0833 (2013.01) [H04W 4/70 (2018.02); H04W 72/23 (2023.01)] | 20 Claims |
1. A method 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 a wireless device operating in a coverage enhancement (CE) mode; 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; wherein the repetition level represents a predetermined number of repeated transmissions; wherein the CE level represents a group of wireless devices with similar radio conditions; the method comprising:
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); and
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.
