A gNB comprising: a memory storing computer-readable instructions; at least one processor coupled to the memory, the at least one processor configured to execute the computer-readable instructions to detect a time domain collision between at least one symbol of a tracking reference signal and at least one symbol of a physical downlink shared data channel scheduled for transmission to a user equipment in a time domain slot, determine that the at least one symbol of the tracking reference signal and the at least one symbol of the physical downlink shared data channel are not quasi co-located; determine a hybrid automatic repeat request status for the physical downlink shared data channel in the time domain slot; adjust, based on the hybrid automatic repeat request status, transmission scheduling of at least one of the at least one symbol of the tracking reference signal and the at least one symbol of the physical downlink shared data channel in the time domain slot in response to the time domain collision; and a transceiver configured to selectively transmit the at least one symbol of the tracking reference signal and the at least one symbol of the physical downlink shared data channel to the user equipment, wherein the transmission scheduling is adjusted by omitting transmission of the at least one symbol of the tracking reference signal in the time domain slot if the hybrid automatic repeat request status indicates retransmission of a transport block on the physical downlink shared data channel within the time domain slot, or puncturing the physical downlink shared data channel at symbol positions corresponding to symbol positions in which the at least one symbol of the tracking reference signal is scheduled for transmission if the hybrid automatic repeat request status indicates a first transmission of a transport block on the shared data channel within the time domain slot. a memory storing computer-readable instructions; at least one processor coupled to the memory, the at least one processor configured to execute the computer-readable instructions to detect a time domain collision between at least one symbol of a tracking reference signal and at least one symbol of a physical downlink shared data channel scheduled for transmission to a user equipment in a time domain slot, determine that the at least one symbol of the tracking reference signal and the at least one symbol of the physical downlink shared data channel are not quasi co-located; determine a hybrid automatic repeat request status for the physical downlink shared data channel in the time domain slot; adjust, based on the hybrid automatic repeat request status, transmission scheduling of at least one of the at least one symbol of the tracking reference signal and the at least one symbol of the physical downlink shared data channel in the time domain slot in response to the time domain collision; and detect a time domain collision between at least one symbol of a tracking reference signal and at least one symbol of a physical downlink shared data channel scheduled for transmission to a user equipment in a time domain slot, determine that the at least one symbol of the tracking reference signal and the at least one symbol of the physical downlink shared data channel are not quasi co-located; determine a hybrid automatic repeat request status for the physical downlink shared data channel in the time domain slot; adjust, based on the hybrid automatic repeat request status, transmission scheduling of at least one of the at least one symbol of the tracking reference signal and the at least one symbol of the physical downlink shared data channel in the time domain slot in response to the time domain collision; and a transceiver configured to selectively transmit the at least one symbol of the tracking reference signal and the at least one symbol of the physical downlink shared data channel to the user equipment, wherein the transmission scheduling is adjusted by omitting transmission of the at least one symbol of the tracking reference signal in the time domain slot if the hybrid automatic repeat request status indicates retransmission of a transport block on the physical downlink shared data channel within the time domain slot, or puncturing the physical downlink shared data channel at symbol positions corresponding to symbol positions in which the at least one symbol of the tracking reference signal is scheduled for transmission if the hybrid automatic repeat request status indicates a first transmission of a transport block on the shared data channel within the time domain slot.
