METHOD AND APPARATUS FOR DETERMINING PHASE TRACKING REFERENCE SIGNAL PATTERN - A simplified explanation of the abstract
This abstract first appeared for US patent application 18476348 titled 'METHOD AND APPARATUS FOR DETERMINING PHASE TRACKING REFERENCE SIGNAL PATTERN
Simplified Explanation
The patent application describes a method and apparatus for determining a phase tracking reference signal (PTRS) pattern in an OFDM signal. The method involves a terminal device receiving scheduled bandwidth threshold information from a network device. The scheduled bandwidth threshold indicated by the information must meet a certain condition, which is that the ratio of the total quantity of modulation symbols in the PTRS pattern to the quantity of subcarriers in the scheduled bandwidth is less than or equal to a first threshold. Based on the scheduled bandwidth threshold, the terminal device determines a PTRS pattern on one OFDM symbol in the OFDM signal.
- The method involves a terminal device receiving scheduled bandwidth threshold information from a network device.
- The scheduled bandwidth threshold must meet a condition related to the ratio of modulation symbols to subcarriers.
- Based on the scheduled bandwidth threshold, the terminal device determines a PTRS pattern on one OFDM symbol in the OFDM signal.
- The network device configures the scheduled bandwidth threshold for the terminal device to ensure demodulation performance.
Potential applications of this technology:
- Wireless communication systems that use OFDM signals can benefit from improved phase tracking with the use of the determined PTRS pattern.
- This technology can be applied in various wireless communication standards, such as Wi-Fi and 5G, to enhance demodulation performance.
Problems solved by this technology:
- The technology solves the problem of accurately determining a PTRS pattern in an OFDM signal, which is crucial for phase tracking in wireless communication systems.
- By ensuring the PTRS pattern meets certain conditions, the technology improves demodulation performance and reduces errors in the received signal.
Benefits of this technology:
- Improved phase tracking accuracy leads to better overall performance in wireless communication systems.
- The technology enhances demodulation performance, resulting in higher data rates and improved reliability in wireless transmissions.
Original Abstract Submitted
This application provides a method and an apparatus for determining a phase tracking reference signal (PTRS) pattern. The method includes: A terminal device receives first scheduled bandwidth threshold information from a network device, where a first scheduled bandwidth threshold indicated by the first scheduled bandwidth threshold information meets a first condition, and the first condition is that a ratio of a total quantity of modulation symbols in a PTRS pattern determined based on the first scheduled bandwidth threshold to a quantity of subcarriers in scheduled bandwidth is less than or equal to a first threshold; and determines a PTRS pattern on one orthogonal frequency division multiplexing (OFDM) symbol in an OFDM signal based on the scheduled bandwidth threshold. In this application, the network device configures, for the terminal device, the scheduled bandwidth threshold that meets the first condition, to ensure demodulation performance of the device.
