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.

Abstract: A method performed in a network node for identifying UEs which are non-compliant with modified CRS operation. The network node enables CRS operation according to a first configuration for a first period. The network node analyzes Information Elements (IE) in RRC Connection Re-establishment Request messages received from UEs during the first period. The network node generates a first set containing identities of UEs whose values in reestablishmentCause IE in the RRC Connection Re-establishment Request messages received during the first period are “otherFailure”. When the first period is finished, the network node enables CRS operation according a second configuration different from the first configuration for a second period. The network node analyzes IE in RRC Reestablishment Request messages received from UEs during the second period.
