Abstract:
Methods and arrangements for managing a retransmission on a Random Access CHannel, “RACH”, in a wireless communication network (100). A device (600; 120) performs (404; 502) the retransmission on the RACH, wherein the retransmission is based on a coverage class associated with the device (600; 120). Basing the retransmission on the coverage class e.g. enables reduction of retransmission collisions when the wireless communication network (100) operates as in Extended Coverage GSM, “EC-GSM”.
