Frequency hopping processing method and apparatus

By configuring frequency domain offsets for terminals through base stations, terminals can determine target offsets within different time units. This solves the problem of frequency domain resource overrun caused by cross-time slot frequency hopping, and improves uplink channel transmission performance and the feasibility of full-duplex communication.

AI Technical Summary

⚠Technical Problem

In the existing technology, when the terminal transmits the Physical Uplink Shared Channel (PUSCH) using the cross-timeslot frequency hopping method, there is no relevant solution to handle the problem that the resources of two adjacent frequency hopping domains exceed the uplink BWP or uplink subband, resulting in a decrease in transmission performance.

⚗Method used

The base station configures one or more frequency domain offsets for the terminal. When the terminal is in different time units in two adjacent hops, it determines the target offset based on specified conditions to ensure that the frequency domain resources do not exceed the uplink BWP or uplink subband range in different time units, and transmits PUSCH using frequency hopping.

🎯Benefits of technology

This enables effective frequency-hopping transmission of PUSCH within different time units, improving the uplink channel transmission performance and the feasibility of full-duplex communication.

Abstract

The present disclosure provides a frequency hopping processing method and device, wherein the method comprises: receiving one or more first offsets configured by a base station for a terminal, the first offset being an available frequency domain offset corresponding to adjacent two hops when the terminal transmits a PUSCH in a frequency domain resource range occupied by an uplink BWP in a frequency hopping manner; when the adjacent two hops are in different time units in the time domain and the frequency domain resources occupied by the adjacent two hops satisfy a specified condition, determining a target offset of the adjacent two hops based on at least the first offset; and transmitting the PUSCH to the base station in a frequency hopping manner in different time units based on the target offset. The present disclosure achieves the purpose of transmitting the PUSCH in a frequency hopping manner in different time units, ensures that the frequency domain resources occupied by the terminal when transmitting the PUSCH in a frequency hopping manner do not exceed the frequency domain resource range occupied by the uplink BWP or the uplink sub-band, improves the transmission performance of the uplink channel, and at the same time improves the feasibility of full-duplex communication.
