TIME DOMAIN RESOURCE ALLOCATION FOR DOWNLINK DATA REPETITIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18485013 titled 'TIME DOMAIN RESOURCE ALLOCATION FOR DOWNLINK DATA REPETITIONS

Simplified Explanation

Methods, systems, and devices for wireless communications are described in this patent application. The abstract explains that a base station can use a downlink control information (DCI) message to indicate timing resources to a user equipment (UE) for multiple downlink data repetitions in a slot.

  • The base station can indicate an explicit time domain resource allocation (TDRA) for one repetition in the TDRA field of the DCI.
  • The UE can determine implicit TDRAs for the other repetitions based on the explicit TDRA.
  • Alternatively, the base station can indicate a total TDRA for the full set of repetitions in the TDRA field.
  • The UE can divide the total TDRA into individual TDRAs for the repetitions.
  • The UE can receive the downlink data repetitions based on determining the TDRAs.
  • The UE can transmit a feedback message in response based on a hybrid automatic repeat request acknowledgment (HARQ-ACK) codebook.

Potential applications of this technology:

  • Wireless communication systems
  • Cellular networks
  • Internet of Things (IoT) devices
  • Mobile devices

Problems solved by this technology:

  • Efficient allocation of timing resources for downlink data repetitions
  • Improved communication reliability and performance
  • Optimal use of available spectrum and resources

Benefits of this technology:

  • Enhanced data transmission efficiency
  • Improved network capacity and throughput
  • Reduced latency and improved responsiveness
  • Enhanced user experience and quality of service


Original Abstract Submitted

Methods, systems, and devices for wireless communications are described. In some systems, a base station may use a downlink control information (DCI) message to indicate timing resources to a user equipment (UE) for multiple downlink data repetitions in a slot. In a first implementation, the base station may indicate an explicit time domain resource allocation (TDRA) for one repetition in the TDRA field of the DCI, and the UE may determine implicit TDRAs for the other repetitions based on the explicit TDRA. In a second implementation, the base station may indicate a total TDRA for the full set of repetitions in the TDRA field, and the UE may divide the total TDRA into individual TDRAs for the repetitions. The UE may receive the downlink data repetitions based on determining the TDRAs and may transmit a feedback message in response based on a hybrid automatic repeat request acknowledgment (HARQ-ACK) codebook.
