1. A method for wireless communications at a user equipment (UE), comprising:
determining, based at least in part on a maximum permissible exposure (MPE) or a specific absorption rate (SAR) associated with a first time period and one or more second power levels of one or more second time periods in an exposure threshold compliance window, an amount of available power or energy for uplink transmissions from the UE during the first time period;
identifying, based at least in part on the amount of available power or energy for uplink transmissions, an uplink data buffer size for a buffer status report, wherein an amount of data indicated by the uplink data buffer size is in accordance with the MPE or SAR, and wherein the uplink data buffer size is different for different amounts of available power or energy for uplink transmissions from the UE during the first time period; and
transmitting the buffer status report to an access network entity.
