Abstract

A wireless device receives message(s) from a base station comprising configuration parameters of a first uplink bandwidth part of a cell. The configuration parameters comprise: a bandwidth part configuration parameter of the first uplink bandwidth part, and random access channel parameters of a random access channel resource. A preamble is transmitted via the random access channel resource on the first uplink bandwidth part. A random access radio network temporary identifier (RA-RNTI) is determined based on the bandwidth part configuration parameter and one or more of the random access channel parameters. A downlink control channel is monitored for a downlink control information addressed to the RA-RNTI in response to the determining. The downlink control information indicates a downlink radio resource of a random access response is received. The random access response is received via the downlink radio resource in response to the downlink control information.

Dependent claims

A method comprising:

receiving, by a wireless device from a base station, one or more messages comprising configuration parameters of a first uplink bandwidth part of a cell, wherein the configuration parameters comprise:
a bandwidth part configuration parameter of the first uplink bandwidth part;
and
random access channel parameters of a random access channel resource;
transmitting a preamble via the random access channel resource on the first uplink bandwidth part;
determining a random access radio network temporary identifier (RA-RNTI) based on the bandwidth part configuration parameter of the first uplink bandwidth part and one or more of the random access channel parameters;
monitoring, in response to the determining, a downlink control channel for a downlink control information addressed to the RA-RNTI;
receiving the downlink control information indicating a downlink radio resource of a random access response;
and
receiving the random access response via the downlink radio resource in response to the downlink control information.
