TECHNIQUES FOR MODIFYING UPLINK COMMUNICATIONS TO AVOID MAXIMUM PERMISSIBLE EXPOSURE (MPE) IN WIRELESS COMMUNICATIONS
Aspects described herein relate to detecting maximum permissible exposure (MPE) events and/or reporting the MPE event, related metrics, associated requests for beam switching or new time division duplexing (TDD) patterns, etc. In an aspect, a MPE event can be detected on at least one component carrier (CC) of multiple CCs configured with a first cell in inter-band carrier aggregation (CA), and one of a MPE report or a beam switching request can be transmitted to a second cell on a different CC of the multiple CCs. In another aspect, the cell can detect the MPE and can transmit, to the device, a beam switching command to switch to a new beam for uplink communications. In another aspect, the cell can transmitting, to another cell having another CC of the multiple CCs configured with the device, an indication to perform beam switching for the device.
