Abstract: Systems and technologies described herein provide functionality for a cellular base station to dynamically indicate a reception (Rx) beam to be used by a user equipment (UE). The Rx beam can be indicated explicitly or implicitly. The UE can, for example, use the Rx beam for Physical Downlink Shared Channel (PDSCH) reception, Channel State Information Reference Signal (CSI-RS) measurements, and/or Channel State Information (CSI) calculation at the UE. Systems and technologies described herein are generally useful for systems that use multiple transmission (Tx) beams and/or that support Coordinated Multipoint (CoMP) transmission technology.

Control channel candidates can be monitored in the second search space instead of the first search space when the uplink transmission overlaps with the first set of symbols.
