Abstract: A communication control method used in a user equipment, a user equipment, an apparatus for controlling a user equipment, and a base station that communicates with user equipment. The user equipment performs a predetermined data transmission in which it transmits uplink user data in an RRC idle state. When the user equipment is in an RRC connected state, it transmits an RRC message to a base station indicating that the user equipment is interested to perform the predetermined data transmission after transitioning to RRC idle mode. The base station receives, from user equipment when the user equipment is in an RRC connected state, the RRC message indicating that the user equipment is interested to perform the predetermined data transmission after transitioning to RRC idle mode.

Abstract: A mobile device supports positioning with positioning reference signals (PRS) on multiple beam by dividing the PRS processing into two separate modes, an acquisition mode and a tracking mode. In acquisition mode, the mobile device performs a fast scan of all of the beams from a base station transmitting PRS using less than the full set of resources for the PRS, i.e., less than the full bandwidth and/or less than the full number of repetitions of the PRS. The mobile device may select the best beams to use for positioning, e.g., based on signal strength metric. In tracking mode, the mobile device tracks the PRS from only the selected beams using the full set of resources for the PRS. The mobile device may return to acquisition mode after a predetermined number of positioning occasions or if the selected beams are no longer valid due to movement or change in conditions.
