Abstract
A wireless device in a radio resource control, RRC, idle or an RRC inactive state communicates via a first cell of a first base station. Based on a communication failure of the first cell, the wireless device in the RRC idle state or RRC inactive state transmits an RRC request message to a second base station. The RRC request message comprises a cell radio network temporary identifier, C-RNTI, of the first cell.
Claims20
A method comprising:
- communicating, by a wireless device in a radio resource control (RRC) idle or a RRC inactive state and via a first cell of a first base station, a packet for a small data transmission;
- and
- transmitting, while in the RRC idle state or the RRC inactive state, to a second base station, based on a communication failure of the first cell of the first base station, a first RRC request message comprising a cell radio network temporary identifier (C-RNTI) of the first cell.
A wireless device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the wireless device to perform operations comprising:
- communicating, in a radio resource control (RRC) idle or a RRC inactive state and via a first cell of a first base station, a packet for a small data transmission;
- and
- transmitting, while in the RRC idle state or the RRC inactive state, to a second base station, based on a communication failure of the first cell of the first base station, a first RRC request message comprising a cell radio network temporary identifier (C-RNTI) of the first cell.
