Abstract
In embodiment methods for managing uplink spatial filter configuration, comprising, a processor of a wireless device may send an initial access signal using two or more spatial filters, wherein each spatial filter directs a beam to a respective uplink (UL) receive (Rx) point, receive from the base station an indication of which beam to use for UL transmissions, and send to the base station another signal using the spatial filter corresponding to the indicated beam. A base station may receive the initial access signal via two or more UL Rx points on two or more beams, determine which of the two or more beams provides a better received signal, send an indication of the better of the two or more beams to the wireless device, and receive from the wireless device another signal on the indicated better of the two or more beams via a corresponding UL Rx point.
