Classification: CPC H | IPC H

Claim 7:
8. A wireless device, comprising:
processing circuitry; and
power supply circuitry configured to supply power to the wireless device,
wherein the processing circuitry is configured to:
initiate a random access procedure in which the wireless device sends a Physical Random Access Channel (PRACH) preamble to a network node; and
apply a receiver configuration for receiving an access response, the receiver configuration determined based at least in part on whether a many-to-one association exists between (a) a downlink signal that, prior to initiating the random access procedure, is used for beam selection, and (b) PRACH preamble indices,
wherein the wireless device is configured with the many-to-one association via a dedicated RRC message that is indicative of at least one of: move the wireless device from connected state to idle or inactive state, or issue a handover command, and
wherein applying the receiver configuration comprises configuring receive weights for receiving the access response differently than receive weights used for receiving the downlink signal on a preferred beam based on the downlink signal and based on the PRACH preamble indices having the many-to-one association.
