Collision Handling of Reference Signals - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240121041 titled 'Collision Handling of Reference Signals

Simplified Explanation

The abstract describes a patent application related to user equipment (UE) decoding control information received via a physical down-link control channel (PDCCH) within a subset of OFDM symbols in a slot, where at least one symbol coincides with a pre-defined symbol location associated with a demodulation reference signal (DM-RS) of a PDSCII.

• Processing circuitry in UE decodes control information from PDCCH received in a subset of OFDM symbols in a slot.
• The subset includes a symbol that aligns with a pre-defined symbol location for a DM-RS of a PDSCII.
• The DM-RS is detected within the slot, starting at a shifted symbol location and following the subset of symbols.
• Downlink data scheduled by PDCCH and received via PDSCH is decoded based on the detected DM-RS.

Original Abstract Submitted

a user equipment (ue) can include processing circuitry configured to decode control information of a physical down-link control channel (pdcch) received via a resource within a control resource set (coreset) occupying a subset of a plurality of ofdm symbols within a slot. at least one of the symbols in the subset coincides with a pre-defined symbol location associated with a demodulation reference signal (dm-rs) of a pdscii. the dm-rs can be detected within the slot, the dm-rs starting at a symbol location that is shifted from the pre-defined symbol location and following the subset of symbols. downlink data scheduled by the pdcch and received via the pdsch can be decoded, where the decoding is based on the detected dm-rs.
