SSB set selection for DRX

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

• receiving, from a base station, a discontinuous reception (DRX) configuration having a DRX ON duration for the UE;
• determining a smallest wakeup duration between a first synchronization signal block (SSB) set and a second SSB set in combination with the DRX ON duration, wherein at least one of the first SSB set and the second SSB set extends outside of the DRX ON duration;
• selecting, from multiple SSB sets including the first SSB set and the second SSB set, an SSB set for an SSB warm up procedure in connection with the DRX ON duration, wherein the UE selects the or a second SSB set from the multiple SSB sets having a smallest smaller time difference relative to the DRX ON duration and providing the smallest wakeup duration in combination with the DRX ON duration;
• and
• waking up to measure the selected SSB set.

An apparatus for wireless communication at a user equipment (UE), comprising:

• means for receiving, from a base station, a discontinuous reception (DRX) configuration having a DRX ON duration for the UE;
• means for determining a smallest wakeup duration between a first synchronization signal block (SSB) set and a second SSB set in combination with the DRX ON duration, wherein at least one of the first SSB set and the second SSB set extends outside of the DRX ON duration;
• select, from multiple SSB sets including the first SSB set and the second SSB set, an SSB set for an SSB warm up procedure in connection with the DRX ON duration, wherein the means for selecting is configured to select the SSB set from the multiple SSB sets having a smallest time difference relative to the DRX ON duration and providing the smallest wakeup duration in the combination with the DRX ON duration;
• and
• means for waking up to measure the selected SSB set.

A non-transitory computer-readable medium storing computer executable code at a user equipment (UE), the code when executed by at least one processor causes the UE to:

• receive, from a base station, a discontinuous reception (DRX) configuration having a DRX ON duration for the UE;
• determine a smallest wakeup duration between a first synchronization signal block (SSB) set and a second SSB set in combination with the DRX ON duration, wherein at least one of the first SSB set and the second SSB set extends outside of the DRX ON duration;
• select, from multiple SSB sets including the first SSB set and the second SSB set, an SSB set for an SSB warm up procedure in connection with the DRX ON duration, wherein the code causes the UE to select the SSB set from the multiple SSB sets having a smallest time difference relative to the DRX ON duration and providing the smallest wakeup duration in the combination with the DRX ON duration;
• and
• wake up to measure the selected SSB.
