Problems solved by technology

[0004] For downlink transmission, the base station can make full use of spectrum resources to meet regulatory requirements, but for uplink transmission, the restrictions of the above regulations undoubtedly bring huge challenges to the allocation of uplink resources, especially when the allocation of uplink resources is required to meet certain special requirements. Can lead to inflexible resource allocation when required

Abstract

The invention provides a resource allocation method, related equipment and a device. The resource allocation method comprises the following steps that a terminal receives a resource allocation instruction used for indicating frequency domain resource allocation from network equipment, wherein the resource allocation indication is used for indicating that a plurality of first resource units allocated to the terminal and the plurality of first resource units are divided into one or more groups, and the number of the first resource units in each group satisfies a product of powers of 2, 3 and 5;and the terminal performs discrete Fourier transform (DFT) based on the plurality of first resource units. By applying the resource allocation method provided by the invention, flexible resource allocation can be carried out, and the spectrum utilization rate is improved.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a technology applied to uplink resource allocation in an unlicensed frequency band scenario. Background technique [0002] The rapid development of wireless communication technology has led to an increasingly scarce spectrum resource, which has promoted the exploration of unlicensed frequency bands. 3GPP introduced License Assisted Access (LAA for short) and enhanced LAA (eLAA for short) in Release 13 (Release-13, R-13 for short) and R-14 respectively. Technology, that is, non-standalone deployment of LTE / LTE-A systems on unlicensed spectrum, which maximizes the use of unlicensed spectrum resources through the assistance of licensed spectrum. [0003] However, there are many regulatory restrictions on the use of unlicensed frequency bands. On the one hand, the signal transmission bandwidth (OCB) of the unlicensed frequency band is limited. Taking Europe as...
