RESTRICTING PDCP CONTROL PDUS ON SPECIFIC LINK

Title:

RESTRICTING PDCP CONTROL PDUS ON SPECIFIC LINK

Document Type and Number:

WIPO Patent Application WO/2018/062884

Kind Code:

A1

Abstract:

A user equipment (UE) determines whether a size of data available for transmission in a PDCP (Packet Data Convergence Protocol) entity of the UE, excluding a size of a PDCP Control PDU (Protocol Data Unit), exceeds a threshold value. Here, the PDCP Control PDU is predetermined to be transmitted through the first link of the bearer. The PDCP entity of the UE informs an indication on (a) the size of the data available for transmission, or (b) the size of the PDCP Control PDU, to a first entity of the UE for the first link based on the determination, and the first entity can transmit a buffer status report to the network based on the indication. Here, the size of the data available for transmission in the PDCP includes the size of the PDCP Data PDU and the size of the PDCP Control PDU.
