Power headroom report triggering by dormant bandwidth part switching

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

• at least one processor;
• and
• at least one memory coupled with the at least one processor, with instructions stored in the at least one memory, the instructions being executable by the at least one processor to cause the apparatus to:
• establish a primary cell connection and a secondary cell connection at the UE;
• initiate, at the UE, a timer for power headroom reporting by the UE based at least in part on activating the secondary cell connection;
• configure a bandwidth part associated with the secondary cell connection to operate in a dormant state;
• receive an indication to configure the bandwidth part to operate in a non-dormant state;
• configure the bandwidth part associated with the secondary cell connection to operate in the non-dormant state based at least in part on the indication;
• and
• determine to refrain from transmitting a power headroom report based at least in part on a status of the timer for power headroom reporting and the indication to configure the bandwidth part to operate in the non-dormant state.

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

• means for establishing a primary cell connection and a secondary cell connection at the UE;
• means for initiating, at the UE, a timer for power headroom reporting by the UE based at least in part on activating the secondary cell connection;
• means for configuring a bandwidth part associated with the secondary cell connection to operate in a dormant state;
• means for receiving an indication to configure the bandwidth part to operate in a non-dormant state;
• means for configuring the bandwidth part associated with the secondary cell connection to operate in the non-dormant state based at least in part on the indication;
• and
• means for determining to refrain from transmitting a power headroom report based at least in part on a status of the timer for power headroom reporting and the indication to configure the bandwidth part to operate in the non-dormant state.

A non-transitory computer-readable medium storing code for wireless communications at a user equipment (UE), the code comprising instructions executable by a processor to:

• establish a primary cell connection and a secondary cell connection at the UE;
• initiate, at the UE, a timer for power headroom reporting by the UE based at least in part on activating the secondary cell connection;
• configure a bandwidth part associated with the secondary cell connection to operate in a dormant state;
• receive an indication to configure the bandwidth part to operate in a non-dormant state;
• configure the bandwidth part associated with the secondary cell connection to operate in the non-dormant state based at least in part on the indication;
• and
• determine to refrain from transmitting a power headroom report based at least in part on a status of the timer for power headroom reporting and the indication to configure the bandwidth part to operate in the non-dormant state.
