The disclosed technology is directed towards user equipment requests for delivery of other system information block (SIB) data from a base station, in which one or more beams for transmitting the other SIB data can be specified by the user equipment based on its state data. Transmitting via only selected beams saves network resources, generally without increasing user equipment retry requests. The user equipment can determine which beam(s) it detects based on beam signal strength data, and determine mobility data of the user equipment. The user equipment determines beam sweeping delivery data based on the detected beam signal strength data and/or the mobility data, and associates the beam sweeping request data with the request for the other SIB data. The network selects one or more beams for sweeping to deliver the other SIB data based on the beam sweeping request data of the user equipment, and possibly other user equipment.

The disclosed technology is directed towards user equipment requests for delivery of other system information block (SIB) data from a base station, in which one or more repetitions of the other SIB data transmissions can be requested in a single request.

The user equipment can measure signal quality and obtain reported signal quality by the base station. The user equipment determines repetition data, based on the signal quality difference, for delivery of the other SIB data.
