System and method for architecture and design for fast beam management

A method performed by a wireless device, the method comprising:

• receiving one or more radio resource control (RRC) messages from a network controller, wherein the one or more RRC messages comprise configuration parameters indicating one or more resources for a first downlink signal;
• receiving, from the network controller, the first downlink signal via the one or more resources;
• deriving a first receive beam based on the first downlink signal;
• indicating to the network controller to receive a first uplink signal based on a transmit beam of the first downlink signal;
• and
• transmitting to the network controller the first uplink signal based on the first receive beam.

A network controller, including:

• at least one processor;
• and
• a non-transitory computer readable storage medium storing programming, the programming including instructions that, when executed by the at least one processor, cause the network controller to perform:
• transmitting one or more radio resource control (RRC) messages to a wireless device, wherein the RRC messages comprise configuration parameters indicating one or more resources for a first uplink signal;
• receiving, via the one or more resources, the first uplink signal from the wireless device;
• deriving a first receive beam based on the first uplink signal;
• indicating to the wireless device to receive a first downlink signal based on a transmit beam of the first uplink signal;
• and
• transmitting, to the wireless device, the first downlink signal based on the first receive beam.
