System and method for beam switching and reporting

An apparatus for wireless communication, the apparatus comprising:

• means for selecting a first beam for communication with a base station;
• means for attempting, through the selected first beam, at least one random access channel (RACH) procedure with the base station;
• means for determining that the at least one RACH procedure failed with the base station;
• and
• means for sending, after a successful RACH procedure with the base station, information indicating an index corresponding to the selected first beam through which the at least one RACH procedure failed, wherein the information indicates that the index is to be excluded from a list of candidate beam indexes based on the failure of the at least one RACH procedure.

An apparatus for wireless communication, the apparatus comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• select a first beam for communication with a base station;
• attempt, through the selected first beam, at least one random access channel (RACH) procedure with the base station;
• determine that the at least one RACH procedure failed with the base station;
• and
• send, after a successful RACH procedure with the base station, information indicating an index corresponding to the selected first beam through which the at least one RACH procedure failed, wherein the information indicates that the index is to be excluded from a list of candidate beam indexes based on the failure of the at least one RACH procedure.

A non-transitory, computer-readable medium storing computer-executable code for wireless communication by a user equipment (UE), comprising code to:

• select a first beam for communication with a base station;
• attempt, through the selected first beam, at least one random access channel (RACH) procedure with the base station;
• determine that the at least one RACH procedure failed with the base station;
• and
• send, after a successful RACH procedure with the base station, information indicating an index corresponding to the selected first beam through which the at least one RACH procedure failed, wherein the information indicates that the index is to be excluded from a list of candidate beam indexes based on the failure of the at least one RACH procedure.
