Beam determination prior to beam activation indication

A base station for wireless communication, comprising:

• a memory;
• and
• one or more processors operatively coupled to the memory, the one or more processors configured to:
• transmit, to a user equipment (UE), a configuration for one or more transmission configuration indicator (TCI) states;
• transmit, to the UE and in a control resource set, downlink control information that schedules a downlink transmission after a time offset;
• prior to transmitting an indication of an activated TCI state of the one or more TCI states to the UE, determine a beam for transmitting the downlink transmission, according to an initial access procedure or the control resource set, based at least in part on at least one of:
• whether the time offset satisfies a threshold value, or
• whether a TCI indication for the control resource set is enabled in the downlink control information;
• and
• transmit, to the UE, the downlink transmission using the beam.

A method of wireless communication performed by a user equipment (UE), comprising:

• receiving a configuration for one or more transmission configuration indicator (TCI) states;
• receiving downlink control information, that schedules a downlink transmission after a time offset, in a control resource set;
• prior to receiving an indication of an activated TCI state of the one or more TCI states, determining a beam for receiving the downlink transmission, according to an initial access procedure or the control resource set, based at least in part on at least one of:
• whether the time offset satisfies a threshold value, or
• whether a TCI indication for the control resource set is enabled in the downlink control;
• and
• receiving the downlink transmission using the beam.

A user equipment (UE) for wireless communication, comprising:

• a memory;
• and
• one or more processors coupled to the memory, the one or more processors configured to:
• determine respective signal-to-interference-plus-noise ratio (SINR) measurements for a group of beams;
• and
• transmit, based at least in part on a receiving a reporting configuration associated with reporting the SINR measurements for the group of beams, a measurement report for the group of beams that identifies the respective SINR measurements.

A non-transitory computer-readable medium storing one or more instructions for wireless communication, the one or more instructions comprising:

• one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the one or more processors to:
• determine respective signal-to-interference-plus-noise ratio (SINR) measurements for a group of beams;
• and
• transmit, based at least in part on a receiving a reporting configuration associated with reporting the SINR measurements for the group of beams, a measurement report for the group of beams that identifies the respective SINR measurements.
