TRACKING REFERENCE SIGNALS IN FULL DUPLEX OPERATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17956588 titled 'TRACKING REFERENCE SIGNALS IN FULL DUPLEX OPERATION

Simplified Explanation

Methods, systems, and devices for wireless communications are described in the patent application. The techniques focus on managing an overlap of a tracking reference signal (TRS) with an uplink subband or a guard band in a subband full duplex (SBFD) slot or symbol.

  • Simplified Explanation:

- The patent application discusses ways to handle the overlap of a tracking reference signal with an uplink subband or guard band in wireless communications. - Techniques include dropping the TRS, puncturing the overlapping portion, or shifting the frequency position of the TRS to the downlink subband(s) of the SBFD slot or symbol.

      1. Potential Applications:

- Wireless communication systems - 5G networks - IoT devices

      1. Problems Solved:

- Efficient management of TRS overlap in wireless communications - Optimization of spectrum usage in SBFD slots or symbols

      1. Benefits:

- Improved signal reliability - Enhanced spectral efficiency - Better overall performance of wireless networks

      1. Potential Commercial Applications:
        1. Optimizing TRS in Wireless Communications for Improved Performance
      1. Possible Prior Art:

- Existing methods for managing TRS overlap in wireless communications - Previous techniques for optimizing spectrum usage in SBFD slots

        1. Unanswered Questions:
        2. How does this technique impact the overall throughput of the wireless communication system?

- Answer: The patent application does not explicitly mention the impact on throughput, so further research or testing may be needed to determine this aspect.

        1. What are the potential challenges in implementing these techniques in real-world wireless networks?

- Answer: The patent application does not address the practical challenges of implementing these techniques, such as compatibility with existing systems or hardware constraints. Additional information or case studies may be required to understand these challenges.


Original Abstract Submitted

Methods, systems, and devices for wireless communications are described. Techniques described herein relate to schemes for managing an overlap of at least part of a tracking reference signal (TRS) with an uplink subband or a guard band in a subband full duplex (SBFD) slot or symbol. In some examples, if a user equipment (UE) and/or a network entity determines that at least a portion of a TRS is scheduled for reception in an uplink subband or a guard band of an SBFD slot or symbol, the UE and/or the network entity may: drop the TRS, puncture the portion of the TRS that overlaps with the uplink subband or the guard band; or may shift the frequency position of the TRS such that the TRS is scheduled within the downlink subband(s) of the SBFD slot or symbol.
