Abstract: A wireless device sends, to an access and mobility management function (AMF) via an access network, a first registration request message comprising a first geographical coordinate of a first geographical location. The wireless device receives a registration accept message comprising a radius value from the AMF. The wireless device moves to a second geographical location. The wireless device determines that a distance between the first geographical coordinate and a second geographical coordinate of the second geographical location is larger than the radius value. In response to the determination, the wireless device sends a second registration request message comprising the second geographical coordinate.

Abstract: Wireless communications for random access procedures are described. A wireless device may send one or more messages as part of a random access procedure.

The downlink control information indicates uplink resources in a plurality of scheduled consecutive subframes for transmission of transport blocks by the wireless device and triggers an SRS transmission in a subframe of the plurality of scheduled consecutive subframes. The SRS is transmitted in the subframe. A position of the subframe in the plurality of scheduled consecutive subframes is determined based on the aperiodic SRS subframe parameter.

Abstract: An automobile device receives first data from one or more transmitters located in an automobile. A random access preamble is transmitted on an uplink carrier to a base station in response to a pre-defined condition being met based on at least one of the following: the first data; a value of an internal timer; and a user input.
