Apparatus and method for acquisition of on-demand system information in connected state

Abstract

A wireless terminal that communicates over a radio interface with a radio access node of a radio access network (RAN). The wireless terminal comprises receiver circuitry, transmitter circuitry, and processor circuitry. The receiver circuitry is configured to receive, in a radio resource control (RRC) connected state, one or more configuration messages via dedicated signaling(s). The one or more configuration messages may comprise a timer configuration for a timer and a configuration for Physical Downlink Control Channel (PDCCH) monitoring. The transmitter circuitry is configured to transmit, in the RRC connected state, a system information (SI) request message to request at least one system information block (SIB). The processor circuitry is configured to start the timer based on the timer configuration and to perform an SI acquisition process. In an example embodiment and mode, the SI acquisition process comprises reception of Downlink Control Information (DCI) on PDCCH based on the configuration for PDCCH monitoring, and reception of Physical Downlink Shared Channel (PDSCH) scheduled by using the DCI. The SI acquisition process continues until the at least one SIB is successfully received or until the timer expires. Methods for operating such wireless terminal and the access node are also provided.
