A method for resource allocation of a PUSCH

By calculating the maximum number of resource blocks when terminal power is limited and combining PUSCH/SRS measurements and HARQ-ACK feedback, PUSCH scheduling is optimized, solving the uplink rate and resource efficiency problems of mid-to-far point terminals, and achieving higher throughput and resource utilization.

AI Technical Summary

Technical Problem

Existing technologies in NR systems fail to effectively consider the uplink power limitations and single measurement errors of mid-to-far point terminals, resulting in poor PUSCH scheduling and reduced uplink rate and air interface resource utilization efficiency.

Method used

By calculating the maximum number of resource blocks when terminal power is limited, and combining PUSCH and SRS measurement results with HARQ-ACK feedback, the signal-to-interference-plus-noise ratio and modulation and coding scheme are dynamically adjusted to optimize single-port or two-port PUSCH scheduling in order to maximize throughput.

Benefits of technology

It improved the uplink speed of the terminal and the utilization efficiency of air interface resources, thus enhancing the user experience.

Abstract

This invention discloses a PUSCH resource allocation method, comprising: updating the signal-to-interference-plus-noise ratio (SIR) of single-port or two-port PUSCH scheduling; calculating the SIR adjustment amount of single-port or two-port PUSCH scheduling; calculating the total SIR of single-port or two-port PUSCH scheduling; and optimizing single-port and two-port PUSCH scheduling based on a maximum throughput algorithm according to the maximum number of resource blocks T, the total SIR of single-port or two-port scheduling, the demodulation threshold of single-port or two-port scheduling, and the maximum number of resource blocks available during the current PUSCH scheduling, to determine the number of ports, modulation and coding scheme, and maximum number of resource blocks for PUSCH scheduling. This method improves the uplink rate of the terminal and the utilization efficiency of valuable air interface resources, thereby enhancing the user experience.
