Title:
COMMUNICATION DEVICE, PROCESSING DEVICE AND METHOD FOR TRANSMITTING DATA UNIT
Document Type and Number:
WIPO Patent Application WO/2019/135626
Kind Code:
A1
Abstract:
The present invention constructs L RLC PDUs, where L is larger than 1; and submit the L RLC PDUs to a medium access control (MAC) layer for a transmission opportunity. The L RLC PDUs include a first RLC PDU having a poll to trigger status reporting at a receiving device and a second RLC PDU not having the poll and having a highest sequence number (SN) among SNs of the L RLC PDUs. The present invention sets a state variable to a highest SN among SNs of RLC PDUs having the poll submitted to the MAC layer, upon submitting the first RLC PDU to the MAC layer.
