Classification: CPC H  Y | IPC H

Claim 14:
15. A wireless device, comprising:
a processor configured with processor executable instructions to:
receive from the base station a downlink path loss threshold;
determine whether a downlink path loss of a signal received from the base station meets the downlink path loss threshold;
send an initial access signal using two or more spatial filters in response to determining that the downlink path loss of the signal from the base station meets the downlink path loss threshold,
wherein each spatial filter directs a beam to a respective uplink (UL) receive (Rx) point that is different from and is in communication with the base station;
receive from the base station an indication that is responsive to the initial access message of which beam to use for UL transmissions; and
send another signal using the spatial filter corresponding to the indicated beam.
