A base station may send an indication of frequency subranges supported by the base station to user equipment, which may respond with an indication of the frequency subranges that are also supported by the user equipment. Additionally, a Spectrum Access System (SAS) controller, using environmental sensing capability sensors, may determine whether non-federal networks are disposed in a coverage area of a base station and neighboring coverage areas. If so, then the SAS may indicate to the base station to send an indication to user equipment in the coverage area to operate using a default power mode. Otherwise, the SAS may indicate to the base station to send an indication to the user equipment to operate using a lower power mode. Moreover, a base station may indicate a regulatory requirement to user equipment using network signaling value of multiple network signaling values corresponding to multiple regulatory requirements of multiple geographical regions.

Among other things, the method and apparatus examples herein provide a solution to the problems that arise regarding the need for a wireless device to achieve source synchronization in a beam-based system, where the wireless communication network does not define “cells” for connected-mode wireless devices. The problems relate to how a wireless device can re-synchronize with its source access node in a beam-based system that mainly relies on self-contained transmissions from transmission points in the network. As one example advantage, the contemplated methods and apparatus enable wireless devices to perform measurements to support mobility procedures even when no data transmissions are scheduled.

Described is an apparatus of a User Equipment (UE). The apparatus may comprise a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to determine that the UE is in an Inactive Radio Resource Control (RRC) state. The second circuitry may be operable to process a first transmission received by the UE while the UE is in the Inactive RRC state, the first transmission carrying a set of one or more Access Control (AC) parameters. The third circuitry may be operable to regulate the sending of a second transmission, in accordance with the set of one or more AC parameters, while the UE is in the Inactive RRC state.

A method for the transmission of data from a data transmitter to a server by means of a cellular network using frequency sub-bands. A modem selects at least one sub-band from among the frequency sub-bands of the frequency plane, the transmitter obtains at least one frequency sub-band selected, the transmitter obtains information representing the quality of service of the connection between the transmitter and the server, the transmitter checks whether the information representing the quality is superior to or equal to a predetermined quality level, the transmitter notifies the modem of a prohibition of selection of at least one previously selected frequency sub-band if the information representing the quality of service of the connection between the transmitter and the server is inferior to the predetermined quality level.
