Transmission and access with multiple panels

A wireless device comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
• receive configuration parameters indicating a first antenna panel and a second antenna panel;
• transmit, via the first antenna panel, a first preamble of a first random access procedure;
• receive a random access response (RAR) message in response to transmitting the first preamble of the first random access procedure;
• switch from the first antenna panel to the second antenna panel;
• ignore, in response to switching from the first antenna panel to the second antenna panel, the received RAR message;
• and
• initiate a second random access procedure based on the second antenna panel.

A system comprising:

• a base station;
• and
• a wireless device comprising:
• one or more processors;
• and memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
• receive, from the base station, configuration parameters indicating a first antenna panel and a second antenna panel;
• transmit, to the base station and via the first antenna panel, a first preamble of a first random access procedure;
• receive a random access response (RAR) message in response to transmitting the first preamble of the first random access procedure;
• switch from the first antenna panel to the second antenna panel;
• ignore, in response to switching from the first antenna panel to the second antenna panel, the received RAR message;
• and
• initiate a second random access procedure based on the second antenna panel.
