Embodiment 1

[0079] Example embodiment 1: User Equipment (UE) for receiving system information, comprising:

[0080] processor; and

[0081] Memory in electronic communication with the processor, where instructions stored in the memory are executable to:

[0082] receiving the first system information periodically broadcast from the eNB;

[0083] determining a type of second system information to additionally receive;

[0084] Transmitting a request containing the type of second system information to the eNB; receiving the requested second system information from the eNB.

Embodiment 2

[0085] Example embodiment 2: The UE of example embodiment 1, wherein the UE receives the requested second system information unicast to the UE.

Embodiment 3

[0086] Example embodiment 3: The UE of example embodiment 1, wherein the requested second system information is broadcast by the eNB.

Abstract

Techniques, apparatus, and methods are provided in conjunction with differentiated delivery of system information (SI) in a wireless communications network.

Description

[0001] This application claims priority to and benefit of U.S. Provisional Patent Application 62 / 367,447, filed July 27, 2016, which is hereby incorporated by reference in its entirety. technical field [0002] The technology relates to wireless communication, and in particular to a method and apparatus for requesting, transmitting and using system information (SI) in wireless communication. Background technique [0003] In a wireless communication system, a radio access network typically comprises one or more access nodes, such as base stations, which communicate with a plurality of wireless terminals over a radio channel over a radio or air interface. In some technologies, such wireless terminals are also referred to as user equipment (UE). A group known as the 3rd Generation Partnership Project ("3GPP") has undertaken to define globally applicable technical specifications and technical reports for current and next generation wireless communication systems. 3GPP Long Term...
