Abstract
When a time domain collision between Tracking Reference Signal (TRS) symbols and downlink shared data channel symbols is detected, the TRS symbols may be multiplexed with the downlink shared data channel symbols from multiple Transmission Reception Points (TRPs) not sharing quasi co-location (QCL) parameters with each other. If a time domain collision between TRS symbols and dynamically or semi-static (e.g., persistent) downlink shared data channel transmissions is detected, transmission and/or reception of the TRS and/or the downlink shared data channel may be adjusted.
Claims20
A radio access network element 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 a tracking reference signal and a shared data channel scheduled for transmission to a user equipment in a time domain slot, and
- adjust transmission scheduling of at least one of the tracking reference signal and the shared data channel in the time domain slot in response to the time domain collision;
- and
- a transceiver configured to selectively transmit the tracking reference signal and the shared data channel to the user equipment.
A user equipment 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 a tracking reference signal and a shared data channel from a gNB in a time domain slot, and
- selectively receive tracking reference signal symbols during the time domain slot in response to the time domain collision.
A method for transmitting data, comprising:
- detecting a time domain collision between a tracking reference signal and a shared data channel scheduled for transmission to a user equipment in a time domain slot;
- adjusting transmission scheduling of at least one of the tracking reference signal and the shared data channel in the time domain slot in response to the time domain collision;
- and
- selectively transmitting the tracking reference signal and the shared data channel to the user equipment.
