PDCP DISCARD MECHANISM FOR EXTENDED REALITY IN WIRELESS NETWORK

Title:

PDCP DISCARD MECHANISM FOR EXTENDED REALITY IN WIRELESS NETWORK

Document Type and Number:

WIPO Patent Application WO/2024/014887

Kind Code:

A1

Abstract:

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Accordingly, embodiments herein disclose a method for discarding PDCP packets for an XR in wireless network (1000) by transmitter (100). The method includes detecting whether a XR discard timer for a PDU Set is expired. In an embodiment, the method includes discarding the subsequent SDU/PDU of the PDU Set, when the XR discard timer for the first SDU/PDU of the PDU Set is expired wherein at least one subsequent SDU/PDU of the PDU Set is already received at the PDCP entity or discarding is done at the time of receiving the subsequent SDU/PDU of the PDU Set at the PDCP entity. In another embodiment, the method includes mapping the subsequent SDU/PDU of the PDU Set to XR discard timer per SDU/PDU, when the XR discard timer for the first SDU/PDU of the PDU Set is not expired at the time of receiving the subsequent SDU/PDU of the PDU Set at the PDCP entity.
