On demand system information triggering

Abstract:

Methods, systems, and devices for wireless communication are described. For example, the described techniques provide for efficiently requesting all (or a threshold number of) system information (SI) messages that are on demand in a random access channel (RACH) procedure. In one example, a user equipment (UE) may transmit a request for all (or a threshold number of) SI messages in a radio resource control (RRC) connection request or message 3 RACH transmission even if the UE is configured with the option to request SI messages individually with one RACH resource per SI message. In another example, a UE may transmit a request for all (or a threshold number of) SI messages on an additional resource (e.g., RACH resource or other resource configured by a base station) when the UE is configured with the option to request SI messages individually with one RACH resource per SI message.
