The UE enters a second RRC_CONNECTED state from the first RRC_IDLE state. The UE suspends the configuration when the UE is in the second RRC_CONNECTED state. The UE resumes the configuration when the UE enters a second RRC_IDLE state from the second RRC_CONNECTED state. The UE performs a second transmission using the PUR when the UE is in the second RRC_IDLE state.

  • Uplink HARQ operation for prose-enabled UEs participating in sidelink discovery operation
    Patent number: 10667119
    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.
