Abstract
A wireless communication device () conditions its use of Preconfigured Uplink Resources (PUR), as preconfigured by a wireless communication network (), on assessing the validity of a Timing Advance (TA) value used by the device () for controlling its uplink transmission timing. The device () maintains a timer () and deems the TA value to be invalid upon expiration of the timer (). In an example case, a device () operating in idle mode performs a PUR-based transmission in dependence on the timer () not being expired. A radio network node () of the network () maintains a like timer (), to maintain an awareness of TA validity at the device () and, for example, sends an updated TA for the device () upon receiving a PUR-based transmission from the device (). The device () and the node () may refresh their respective timers, in association with the TA update.
