METHOD AND APPARATUS FOR DOWNLINK AND UPLINK TRANSMISSION IN FULL-DUPLEX SYSTEMS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18353780 titled 'METHOD AND APPARATUS FOR DOWNLINK AND UPLINK TRANSMISSION IN FULL-DUPLEX SYSTEMS

Simplified Explanation

The patent application describes methods and apparatuses for downlink and uplink transmissions in full-duplex systems. Specifically, it focuses on a method for operating a user equipment (UE) to receive a physical downlink shared channel (PDSCH) in a reception bandwidth on a cell.

  • The UE receives first information for a first modulation and coding scheme (MCS) table associated with a first frequency-domain subband in the reception bandwidth.
  • The UE also receives second information for a second MCS table associated with a second frequency-domain subband in the reception bandwidth.
  • Additionally, the UE receives third information for a condition.
  • At least one of the first and second frequency-domain subbands is one of a subband full-duplex (SBFD) downlink (DL) subband, an SBFD flexible subband, or an SBFD uplink (UL) subband.
  • The method involves determining whether the condition is valid for reception in a slot or symbol.
  • If the condition is valid, the UE receives the PDSCH in the slot or symbol based on the first MCS table.
  • If the condition is not valid, the UE receives the PDSCH in the slot or symbol based on the second MCS table.

Potential applications of this technology:

  • Full-duplex wireless communication systems
  • Cellular networks
  • Wireless devices and equipment

Problems solved by this technology:

  • Efficient utilization of frequency-domain subbands in full-duplex systems
  • Improved reception of physical downlink shared channels
  • Enhanced flexibility in determining modulation and coding schemes based on conditions

Benefits of this technology:

  • Increased capacity and throughput in wireless communication systems
  • Improved spectral efficiency
  • Enhanced reliability and performance of downlink transmissions in full-duplex systems


Original Abstract Submitted

Methods and apparatuses for downlink and uplink transmissions in full-duplex systems. A method for operating a user equipment (UE) for receiving a physical downlink shared channel (PDSCH) includes receiving: first information for a first modulation and coding scheme (MCS) table associated with a first frequency-domain subband in a reception bandwidth on a cell, second information for a second MCS table associated with a second frequency-domain subband in the reception bandwidth, and third information for a condition. At least one of the first and second frequency-domain subbands is one of a subband full-duplex (SBFD) downlink (DL) subband, an SBFD flexible subband, or an SBFD uplink (UL) subband. The method further includes determining whether the condition is valid for reception in a slot or symbol and receiving the PDSCH in the slot or symbol based on the first MCS table when valid and the second MCS table when not valid.
