Abstract

A wireless device receives at least one message from a base station. The at least one message comprises uplink configuration parameters for a cell of the base station. The uplink configuration parameters indicate: a first uplink; a second uplink; and a power value for selecting one of the first uplink and the second uplink. The wireless device determines a scaled power value based on: the power value; and a moving speed of the wireless device. The wireless device selects as a selected uplink, one of the first uplink and the second uplink based on the scaled power value. The wireless device transmits a random access preamble via the selected uplink.

Dependent claims

A method comprising:

receiving, by a wireless device from a base station, at least one message comprising uplink configuration parameters for a cell of the base station, the uplink configuration parameters indicating:
a first uplink carrier;
a second uplink carrier;
and
a power threshold for selecting one of the first uplink carrier and the second uplink carrier;
determining, by the wireless device, a scaled power threshold based on the configured power threshold and a moving speed of the wireless device;
selecting as a selected uplink carrier, by the wireless device, one of the first uplink carrier and the second uplink carrier based on the scaled power threshold;
and
transmitting, by the wireless device, a random access preamble via the selected uplink carrier.
