Abstract
A method, a computer-readable medium, and an apparatus are provided for wireless communication at a user equipment. The UE receives an indication from a base station that a medium access control-control element (MAC-CE) activation of a pathloss reference signal is enabled. The UE receives a MAC-CE activating the pathloss reference signal. The UE determines the pathloss reference signal based on the MAC-CE and the indication that indicates that the MAC-CE activation of the pathloss reference signal is enabled. Then, the UE estimates a downlink pathloss based on the pathloss reference signal that is activated by the MAC-CE.
Claims45
A method of wireless communication at a user equipment (UE), comprising:
- receiving an indication in radio resource control (RRC) signaling from a base station that a medium access control-control element (MAC-CE) activation of a pathloss reference signal is enabled;
- receiving a MAC-CE activating the pathloss reference signal;
- determining the pathloss reference signal based on the MAC-CE and the indication that indicates the MAC-CE activation of the pathloss reference signal is enabled;
- and
- estimating a downlink pathloss based on the pathloss reference signal that is activated by the MAC-CE.
An apparatus for wireless communication at a user equipment (UE), comprising:
- memory;
- and
- at least one processor coupled to the memory, the memory and the at least one processor being configured to:
