Title:
FAILURE DETECTION IN WIRELESS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/051406
Kind Code:
A1
Abstract:
This document discloses a solution for detecting communication failures. According to an aspect, a method comprises: detecting a first communication failure indication in uplink transmission and, as a response to said detecting, incrementing a failure counter and starting a failure count timer; while the failure count timer is running, if a new communication failure indication is detected, omitting incrementing the failure counter; after expiry of the failure count timer and while the failure count timer is not running, if a new communication failure indication is detected, incrementing the failure counter; in response to the failure counter reaching a determined count value, triggering reporting of communication failure; and in response to reporting the communication failure, receiving a message comprising an operating parameter.
