Abstract:
The invention relates to an improved transmission protocol for uplink data packet transmission. A transmission counter of the transmission protocol counts the number of transmissions the user terminal has performed for a data packet. The user terminal participates in sidelink discovery operation with other user terminals based on sidelink discovery gaps. The user terminal cannot transmit and/or receive signals under control of the transmission protocol when participating in sidelink discovery operation during the sidelink discovery gaps. A processor of the user terminal determines whether a retransmission of a data packet, which is triggered by the transmission protocol, was not performed because the transmission protocol operation collided with one of the sidelink discovery gaps. In case of collision, the processor operates the transmission counter such that the colliding retransmission of the data packet does not result in an increment of the transmission counter of the transmission protocol for the data packet.
