Abstract:
The embodiments of the present application provide a data transmission method and apparatus, and a communication device. In one aspect, the method comprises: a PDCP layer receiving a first SDAP PDU, which is sent by an SDAP layer, wherein the first SDAP PDU is a downlink SDAP control PDU. In another aspect, a terminal device receives a second SDAP PDU, which is sent by a network device, wherein the second SDAP PDU is a downlink SDAP data PDU. In a further aspect, when a first node determines that first data in a GOP is lost, the first node discards second data in the GOP. In a further aspect, a PDCP layer of a first node receives a data recovery instruction, which is sent by a second node, wherein the data recovery instruction is used for triggering the PDCP layer of the first node to execute data recovery for part of data.
