Quasi-Co-Located Assumption for Aperiodic CSI-RS for Multi-TRP Operation - A simplified explanation of the abstract

This abstract first appeared for US patent application 17912446 titled 'Quasi-Co-Located Assumption for Aperiodic CSI-RS for Multi-TRP Operation

Simplified Explanation

The patent application describes techniques for determining a quasi-co-located assumption for aperiodic channel state information reference signals in a wireless communication system. Here are the key points:

• The wireless device establishes wireless links with multiple transmission-reception-points of a cellular network.
• The wireless device receives downlink control information.
• The wireless device determines a quasi-co-located assumption for aperiodic channel state information reference signals for the downlink control information.
• If the scheduling offset for the downlink control information is below a scheduling offset threshold, signals received according to the quasi-co-located assumption are buffered by the wireless device.

Potential Applications

• This technology can be applied in wireless communication systems, particularly in cellular networks.
• It can improve the efficiency and reliability of wireless links between a wireless device and multiple transmission-reception-points.

Problems Solved

• The technology solves the problem of efficiently determining a quasi-co-located assumption for aperiodic channel state information reference signals in multi-transmission-reception-point operation.
• It addresses the issue of scheduling offset for downlink control information and provides a buffering mechanism to handle low scheduling offsets.

Benefits

• Improved wireless link establishment with multiple transmission-reception-points.
• Enhanced efficiency and reliability of wireless communication in cellular networks.
• Better management of aperiodic channel state information reference signals.

Original Abstract Submitted

This disclosure relates to techniques for determining a quasi-co-located assumption for aperiodic channel state information reference signals for multi-transmission-reception-point operation in a wireless communication system. A wireless device may establish wireless links with multiple transmission-reception-points of a cellular network. The wireless device may receive downlink control information. The wireless device may determine a quasi-co-located assumption for aperiodic channel state information reference signals for the downlink control information. Signals received according to the quasi-co-located assumption for aperiodic channel state information reference signals may be buffered by the wireless device if a scheduling offset for the downlink control information is below a scheduling offset threshold.
