System Information Request and Acquisition in a Connected Mode

Abstract:

A user equipment (UE) in a connected mode with respect to a base station transmits a request for desired system information via dedicated uplink signaling, thus increasing the probability of successful reception of the request as compared to transmission over a contention based channel. (The request may identify one or more desired system information blocks, or, one or more desired block portions.) The base station may transmit the desired system information using dedicated downlink signaling, thereby avoiding collisions with unicast downlink transmissions to the UE. Alternatively, the base station may simply broadcast the desired system information. The base station may also transmit, via dedicated downlink signaling, an indication of whether the request is granted or not. The disclosed mechanisms may support modern services such as Vehicle-to-Everything (V2X) and Multimedia Broadcast Multicast Service (MBMS).
