Claim 7:
8. A method performed by a processor of a base station for managing uplink spatial filter configuration, comprising:
broadcasting a signal comprising information configured to enable a wireless device to transmit an initial access signal on two or more beams;
receiving from the wireless device the initial access signal, responsive to the broadcast signal, on two or more beams via two or more uplink (UL) receive (Rx) points that are different from and are in communication with the base station;
determining which of the two or more beams provides a better received signal;
sending an indication that is responsive to the initial access message of the better of the two or more beams to the wireless device;
sending to the wireless device a downlink path loss threshold configured to enable the wireless device to determine whether a downlink path loss of a signal received from the base station meets the downlink path loss threshold; and
receiving from the wireless device another signal on the indicated better of the two or more beams via a corresponding UL Rx point.
