TIMING ADVANCE VALIDATION FOR SMALL DATA TRANSMISSION BY WIRELESS DEVICE

Title:

TIMING ADVANCE VALIDATION FOR SMALL DATA TRANSMISSION BY WIRELESS DEVICE

Document Type and Number:

WIPO Patent Application WO/2024/031224

Kind Code:

A1

Abstract:

This application regards timing advance (TA) validation for small data transmission (SDT) by a wireless device. The wireless device calculates a RSRP value based on a receipt of one or more messages, where the particular messages to trigger the RSRP calculation can be indicated to the wireless device by a flag in a message received from a cellular wireless network. Exemplary messages include a radio resource control (RRC) release message, with or without a SDT configuration, a medium access control (MAC) control element (CE) TA command message, or a random-access response (RAR) message. The wireless device measures and stores the RSRP value to use for subsequent validation of a TA value.
