AI Technical Summary

Technical Problem

Existing wireless communication systems suffer from inefficiency in time-domain resource allocation and insufficient granularity of user multiplexing, especially in communications using time-domain waveforms, where efficient resource allocation is difficult to achieve.

Method used

The Time Domain Resource Allocation (TDRA) is based on Time Domain Resource Blocks (RBs) or Time Domain RB Groups. Communication resources are indicated and allocated in units of sub-symbols. Base stations and User Equipment (UE) communicate according to the TDRA.

Benefits of technology

It improves the resource allocation efficiency of time-domain waveform communication, enables more refined user multiplexing, and enhances communication quality and spectrum utilization.

Abstract

In summary, various aspects of this disclosure relate to wireless communication. In some aspects, a user equipment (UE) can receive from a base station an indication of a time-domain resource allocation (TDRA) for communication using time-domain waveforms, either in units of time-domain resource blocks (RBs) or groups of time-domain RBs. The unit of a time-domain RB or group of time-domain RBs can be a sub-symbol unit. The UE can communicate with the base station using time-domain waveforms, at least in part, based on the TDRA used for communication. Numerous other aspects are described.
