Abstract
Example embodiments of the present disclosure relate to an effective mechanism for handing the scenario of discontinuous coverage. In this solution, a terminal device with a plurality of paths including a first path determines, at a first entity of the terminal device configured, a successful transmission associated with a packet data convergence protocol (PDCP) data packet data unit (PDU) on the first path, the first path being an indirect path, the first entity corresponding to the first path, a layer of the first entity being lower than a PDCP layer. Further, the terminal device performs one of the following transmitting, to a PDCP entity of the terminal device, a confirmation indication indicating the successful transmission; or disabling to transmit the confirmation indication to the PDCP entity.
