DOWNLINK COMMON SIGNALING IN A SINGLE FREQUENCY NETWORK TRANSMISSION SCHEME - A simplified explanation of the abstract

This abstract first appeared for US patent application 17656592 titled 'DOWNLINK COMMON SIGNALING IN A SINGLE FREQUENCY NETWORK TRANSMISSION SCHEME

Simplified Explanation

Abstract

The abstract of this patent application describes a wireless communication system where a user equipment (UE) can receive downlink control information (DCI) from multiple transmit-receive points (TRPs) and receive downlink common signaling in a common search space (CSS) associated with a single frequency network (SFN) control resource set (CORESET).

  • The UE can receive DCI from multiple TRPs.
  • The DCI includes a radio network temporary identifier (RNTI) that schedules downlink common signaling.
  • The UE can receive the downlink common signaling in a CSS associated with a SFN CORESET.
  • The SFN CORESET is activated with two transmission configuration indicator (TCI) states.
  • The UE can receive the downlink common signaling based on its capability of an SFN transmission scheme.

Potential Applications

  • This technology can be applied in wireless communication systems to improve the efficiency of downlink control signaling.
  • It can enable UEs to receive downlink common signaling from multiple TRPs, enhancing the overall system performance.
  • The use of SFN transmission schemes can improve the reception of downlink common signaling in a CSS.

Problems Solved

  • The technology solves the problem of efficiently scheduling downlink common signaling in wireless communication systems.
  • It addresses the challenge of receiving downlink common signaling from multiple TRPs.
  • The use of SFN transmission schemes solves the problem of improving the reception of downlink common signaling.

Benefits

  • Improved efficiency in downlink control signaling.
  • Enhanced system performance by allowing UEs to receive downlink common signaling from multiple TRPs.
  • Better reception of downlink common signaling through the use of SFN transmission schemes.


Original Abstract Submitted

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a first transmit-receive point (TRP) and a second TRP, downlink control information (DCI) with a radio network temporary identifier (RNTI) that schedules downlink common signaling. The UE may receive, from one or more of the first TRP or the second TRP based at least in part on the DCI, the downlink common signaling in a common search space (CSS) associated with a single frequency network (SFN) control resource set (CORESET) that is activated with two transmission configuration indicator (TCI) states, wherein the downlink common signaling is received from one or more of the first TRP or the second TRP based at least in part on a UE capability of an SFN transmission scheme for reception of the downlink common signaling. Numerous other aspects are described.
