EFFICIENT SRS RESOURCE INDICATION METHODS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240305421 titled 'EFFICIENT SRS RESOURCE INDICATION METHODS

Simplified Explanation:

The patent application describes a method for a wireless device to transmit an uplink transmission efficiently by configuring sounding reference signal (SRS) resources and mapping them to multiple-input multiple-output (MIMO) layers.

  • The wireless device receives signaling to configure multiple SRS resources.
  • It then receives an indication of a selected plurality of SRS resources for the transmission.
  • The device transmits multiple MIMO layers of a Physical Uplink Shared Channel (PUSCH) transmission.
  • The selected SRS resources map to the MIMO layers, with fixed order indexes provided for mapping.

Key Features and Innovation:

  • Efficient uplink transmission method for wireless devices.
  • Configuration and mapping of SRS resources to MIMO layers.
  • Indication of selected SRS resources for transmission optimization.

Potential Applications:

  • 5G and future wireless communication systems.
  • IoT devices requiring efficient uplink transmissions.
  • Mobile devices for high-speed data transfer.

Problems Solved:

  • Optimization of uplink transmission in wireless devices.
  • Efficient use of resources for MIMO transmissions.

Benefits:

  • Improved data transmission performance.
  • Enhanced spectral efficiency.
  • Reduced interference in wireless networks.

Commercial Applications:

Potential commercial applications include:

  • Telecommunications companies for improved network performance.
  • IoT device manufacturers for efficient data transfer.
  • Mobile device manufacturers for enhanced connectivity.

Questions about the Technology:

1. How does this method improve the efficiency of uplink transmissions in wireless devices? 2. What are the key advantages of mapping SRS resources to MIMO layers for data transmission efficiency?


Original Abstract Submitted

a method of transmitting an uplink transmission by a wireless device is disclosed. the method comprises a wireless device receiving signaling configuring the wireless device with a plurality of sounding reference signal (srs) resources. the wireless device subsequently receives an indication, in a physical layer downlink control channel, of a selected plurality of srs resources selected from among the plurality of configured srs resources and transmits a plurality of multiple-input multiple-output (mimo) layers of a pusch transmission. the selected plurality of srs resources map to respective ones of the plurality of mimo layers and the indication of the selected plurality of srs resources includes srs resource indexes with a fixed order that corresponds to an order in which the srs resources of the selected plurality of srs resources are mapped to the mimo layers.
