The embodiments herein relate to a method in a transceiver (110) for permitting access to a cellular communications system (100). The transceiver (110) is configured to transmit traffic to a communication node (101,120). The transceiver (110) receives a permission message from the communication node (101,120). The permission message indicates permission to a group of transceivers to transmit an access request message indicating a request to transmit the traffic to the communication node (101, 120). The transceiver (110) determines whether the transceiver (110) is comprised in the group of transceivers having permission to transmit the access request message based on the received permission message.
