Document Type and Number:
WIPO Patent Application WO/2022/099586
Kind Code:
A1
Abstract:
Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. According to embodiments of the present disclosure, a source network device receives a first PDU of tunneling protocol comprising a first sequence number. The source network device transmits a second PDU of PDCP comprising a second sequence number which is at least partially same as the first sequence number. In this way, it ensures that the PDCP sequence number is aligned with the tunneling protocol sequence number.
