Abstract
Systems, apparatuses, and methods are described for wireless communications. Devices may exchange information regarding a radio link failure and/or a handover. The information may comprise a radio link failure report which may comprise an indication of packet duplication.
Claims20
A method comprising:
- receiving, by a wireless device from a first base station, a packet duplication activation command for duplication of one or more packet data convergence protocol (PDCP) packets associated with a first bearer;
- transmitting, based on the packet duplication activation command, one or more duplicated PDCP packets associated with the first bearer;
- determining a connection failure associated with a first cell of the first base station;
- determining, based on the connection failure, a second cell of a second base station for a radio resource control connection to the second base station;
- and
- transmitting, to the second base station, a radio resource control message comprising a radio link failure report comprising a first information element indicating that at least one of the one or more PDCP packets was duplicated at a time associated with the connection failure.

A method comprising:
- receiving, by a wireless device from a first base station, a first radio resource control message comprising one or more packet data convergence protocol (PDCP) packet duplication configuration parameters indicating that PDCP packets associated with a first bearer are duplicated;
- receiving, from the first base station, a packet duplication activation command for the first bearer;
- transmitting, based on the packet duplication activation command and the one or more PDCP packet duplication configuration parameters, one or more duplicated PDCP packets associated with the first bearer;
- determining a connection failure associated with a first cell of the first base station;
- determining, based on the connection failure, a second cell of a second base station for a radio resource control connection to the second base station;
- and
- transmitting, to the second base station, a second radio resource control message comprising a radio link failure report comprising a first information element indicating that PDCP packets were duplicated at a time associated with the connection failure.

A method comprising:
- transmitting, by a first base station to a wireless device, a first radio resource control message comprising one or more packet data convergence protocol (PDCP) packet duplication configuration parameters indicating that one or more PDCP packets associated with a first bearer are duplicated;
- transmitting, to the wireless device, a packet duplication activation command for the first bearer;
- receiving, from a second base station, a radio link failure report comprising a first information element indicating that at least one of the one or more PDCP packets were duplicated at a time associated with a connection failure associated with a first cell of the first base station;
- and
- configuring, based on the first information element, one or more radio resource configuration parameters.
