RECEPTION OF CONTROL SIGNALING IN PRESENCE OF INTERFERENCE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18325932 titled 'RECEPTION OF CONTROL SIGNALING IN PRESENCE OF INTERFERENCE

Simplified Explanation

The patent application describes apparatuses and methods for receiving control signaling in the presence of interference. Specifically, it focuses on a method for receiving physical downlink control channels (PDCCHs) in a new radio (NR) radio access technology (RAT) while considering interference from a long term evolution (LTE) RAT common reference signal (CRS).

  • The method involves transmitting an indication of the receiver's capability to receive PDCCHs over symbols that do not include resource elements (REs) for the CRS.
  • The indication also includes the capability to receive PDCCHs over symbols that do include REs for the CRS.
  • The method further includes receiving information about the parameters of the CRS and using this information to determine the REs for the CRS in the symbols of the PDCCH.
  • Finally, the PDCCH is received based on the determined REs for the CRS in the symbols of the PDCCH.

Potential applications of this technology:

  • Wireless communication systems using new radio access technology (NR)
  • Interference management in the presence of long term evolution (LTE) signals

Problems solved by this technology:

  • Interference caused by long term evolution (LTE) signals in new radio (NR) communication systems
  • Efficient reception of physical downlink control channels (PDCCHs) in the presence of interference

Benefits of this technology:

  • Improved reliability and performance of wireless communication systems
  • Enhanced interference management capabilities in mixed RAT environments


Original Abstract Submitted

Apparatuses and methods for reception of control signaling in the presence of interference. A method for receiving physical downlink control channels (PDCCHs) includes transmitting an indication for one of a first capability to receive PDCCHs over symbols only when at least one of the symbols does not include resource elements (REs) for a common reference signal (CRS) and a second capability to receive PDCCHs over symbols when any of the symbols include REs for the CRS. A PDCCH is according to a new radio (NR) radio access technology (RAT). The CRS is according to a long term evolution (LTE) RAT. The method further includes receiving first information for parameters of the CRS, determining, based on the parameters of the CRS, the REs for the CRS in symbols of the PDCCH, and receiving the PDCCH based on the REs for the CRS in symbols of the PDCCH.
