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

This abstract first appeared for US patent application 18212635 titled 'Collision Handling of Reference Signals

Simplified Explanation

The abstract describes a patent application related to a user equipment (UE) decoding control information of a physical down-link control channel (PDCCH) received 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. The DM-RS is detected within the slot, starting at a shifted symbol location, and downlink data scheduled by the PDCCH is decoded based on the detected DM-RS.

• User equipment (UE) includes processing circuitry to decode control information of a physical down-link control channel (PDCCH) received within a subset of OFDM symbols in a slot.
• The subset of symbols includes at least one symbol that aligns with a pre-defined symbol location associated with a demodulation reference signal (DM-RS) of a PDSCII.
• The DM-RS is detected within the slot, starting at a shifted symbol location, and is used to decode downlink data scheduled by the PDCCH and received via the PDSCH.

How does this technology impact the overall network capacity in wireless communication systems?

This technology can potentially improve network capacity by enhancing the efficiency of decoding control information and downlink data, leading to better resource utilization and overall network performance.

What are the potential security implications of using demodulation reference signals for decoding downlink data in wireless communication systems?

The use of demodulation reference signals for decoding downlink data may introduce security vulnerabilities if not properly implemented, such as potential signal interference or unauthorized access to sensitive data. It is essential to address these security concerns to ensure the integrity and confidentiality of data transmission.

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.
