Handling Multi-TRP Transmissions - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240348385 titled 'Handling Multi-TRP Transmissions

The abstract of this patent application describes a user equipment (UE) configured with multi-transmission and reception point (multi-TRP) operation in a 5G New Radio (NR) wireless network. The UE can handle two overlapping Physical Downlink Shared Channel (PDSCH) transmissions and determine if a Demodulation Reference Signal (DMRS) collides with a Cell-Specific Reference Signal (CRS) from a Long Term Evolution (LTE) transmission.

• The UE groups capabilities of handling two overlapping PDSCH transmissions into multiple groups.
• It determines the UE capability of handling two overlapping PDSCH transmissions based on these groups.
• The UE then transmits this capability to a Next Generation NodeB (gNB) of a 5G NR wireless network.
• It also checks if the CRS originated from the same multi-TRP as the DMRS.

1. 1. 1. Potential Applications

This technology can be applied in 5G NR wireless networks to enhance the efficiency of handling overlapping PDSCH transmissions and avoid collisions between DMRS and CRS signals.

Original Abstract Submitted

a user equipment (ue) is configured with multi-transmission and reception point (multi-trp) operation. the ue groups capabilities of handling two overlapping physical downlink shared channel (pdsch) transmissions into a plurality of groups, determining a ue capability of handling two overlapping pdsch transmissions based on the plurality of groups and transmits the ue capability to a next generation nodeb (gnb) of a 5g new radio (nr) wireless network. the ue also determines if a demodulation reference signal (dmrs) of a physical downlink shared channel (pdsch) transmission collides with a cell-specific reference signal (crs) of a long term evolution (lte) transmission and determines if the crs originated from a same multi-transmission/reception point (trp) as the dmrs.
