Abstract

A method performed by a network node serving a first and second user equipment (UE). The method includes the network node receiving, during a first time slot, a first combined signal comprising a first message transmitted by the first UE and a second message transmitted by the second UE. The method also includes the network node attempting to decode the first message transmitted by the first UE. The method further includes the network node, as a result of failing to decode the first message transmitted by the first UE, transmitting a negative acknowledgement to the first and second UE without attempting to decode the second message.
