Latency Reduction in a Multi-Beam Wireless Communication System

A method, comprising:

• receiving beam and channel state information (CSI) measurement configuration information from a cellular base station, wherein the beam and CSI measurement configuration information indicates beam measurement reference signal resources to use for beam and CSI measurements;
• performing beam measurements using the beam measurement reference signal resources;
• performing CSI measurements using the beam measurement reference signal resources;
• and
• providing a CSI report to the cellular base station based at least in part on the CSI measurements.

An apparatus, comprising:

• a processor configured to cause a wireless device to:
• receive beam and channel state information (CSI) measurement configuration information from a cellular base station, wherein the beam and CSI measurement configuration information indicates beam measurement reference signal resources to use for beam and CSI measurements;
• perform beam measurements using the beam measurement reference signal resources;
• perform CSI measurements using the beam measurement reference signal resources;
• and
• provide a CSI report to the cellular base station based at least in part on the CSI measurements.
