Abstract
Methods and apparatus are provided for aggressive beam selection during a handover procedure. A User Equipment (UE) measures a plurality of candidate downlink beams of a target base station (BS), wherein measurement opportunities for each of the candidate downlink beams are scheduled periodically. The UE reports measurements relating to one or more of the measured candidate downlink beams to a source BS. The UE receives a command to handover to the target BS, and in response to receiving the command, attempts to find a new downlink beam of the target BS having a corresponding measurement opportunity that is earlier than a next measurement opportunity of one of the one or more candidate downlink beam.
Claims28
A method of wireless communication by a User Equipment (UE), comprising:
- measuring a plurality of candidate downlink beams of a target base station (BS), wherein measurement opportunities for each of the candidate downlink beams are scheduled periodically;
- reporting measurements relating to one or more of the measured candidate downlink beams to a source BS;
- receiving a command to handover to the target BS;
- and
- in response to receiving the command, searching for a new downlink beam of the target BS having a corresponding measurement opportunity that is earlier than a next measurement opportunity of one of the reported one or more candidate downlink beams.
An apparatus for wireless communication by a User Equipment (UE), comprising:
- means for measuring a plurality of candidate downlink beams of a target base station (BS), wherein measurement opportunities for each of the candidate downlink beams are scheduled periodically;
- means for reporting measurements relating to one or more of the measured candidate downlink beams to a source BS;
- means for receiving a command to handover to the target BS;
- and
- means for, in response to receiving the command, searching for a new downlink beam of the target BS having a corresponding measurement opportunity that is earlier than a next measurement opportunity of one of the reported one or more candidate downlink beams.
An apparatus for wireless communication by a User Equipment (UE), comprising:
- at least one processor configured to:
- measure a plurality of candidate downlink beams of a target base station (BS), wherein measurement opportunities for each of the candidate downlink beams are scheduled periodically;
- report measurements relating to one or more of the measured candidate downlink beams to a source BS;
- receive a command to handover to the target BS;
- and
- in response to receiving the command, searching for a new downlink beam of the target BS having a corresponding measurement opportunity that is earlier than a next measurement opportunity of one of the reported one or more candidate downlink beams;
- and
- a memory coupled to the at least one processor.
A computer-readable medium for wireless communication by a User Equipment (UE), the computer-readable medium storing instructions which when processed by at least one processor performs a method comprising:
- measuring a plurality of candidate downlink beams of a target base station (BS), wherein measurement opportunities for each of the candidate downlink beams are scheduled periodically;
- reporting measurements relating to one or more of the measured candidate downlink beams to a source BS;
- receiving a command to handover to the target BS;
- and
- in response to receiving the command, searching for a new downlink beam of the target BS having a corresponding measurement opportunity that is earlier than a next measurement opportunity of one of the reported one or more candidate downlink beams.
