AI Technical Summary

Technical Problem

In the prior art, when a single downlink control information (DCI) schedules multiple component carriers (CCs), the DCI overhead is too large because each CC uses independent transmission parameters.

Method used

The configuration information indicates that multiple CCs use the same codeword, reducing the number of independent instructions for each CC in the DCI and using a common codeword for transmission.

Benefits of technology

It effectively reduces DCI overhead, simplifies the frequency domain resource indication process, and improves the uniformity and efficiency of transmission parameters.

Abstract

The invention provides a frequency domain resource indication method and a related device, which are used for reducing the overhead of first indication information. The method provided by the invention comprises the following steps: receiving configuration information from network equipment, wherein the configuration information is used for configuring or indicating a plurality of carrier units (CC) adopting the same code word; receiving first indication information from the network equipment, wherein the first indication information is used for indicating the frequency domain resource allocation condition of the plurality of CCs; and determining the frequency domain resource allocated to the terminal device according to the configuration information and the first indication information.
