Embodiment Construction

[0070] Hereinafter, some terms used in the present invention will be explained to facilitate the understanding of those skilled in the art.

[0071] 1) A terminal, which may also be referred to as user equipment, is a device that provides voice and / or data connectivity to a user, and may include, for example, a handheld device with a wireless connection function, or a processing device connected to a wireless modem. The user equipment may communicate with the core network via a radio access network (Radio Access Network, RAN), and exchange voice and / or data with the RAN. The user equipment may include UE, wireless terminal equipment, mobile terminal equipment, subscriber unit (SubscriberUnit), subscriber station (Subscriber Station), mobile station (Mobile Station), mobile station (Mobile), remote station (Remote Station), access Access Point (AP), Remote Terminal (Remote Terminal), Access Terminal (Access Terminal), User Terminal (User Terminal), User Agent (User Agent), or U...

Abstract

The invention discloses an uplink data transmission method and equipment and is used for improving resource allocation flexibility and uplink transmission efficiency of a terminal. The uplink data transmission method comprises the steps that the terminal receives a scheduling signal sent by network equipment, wherein the scheduling signal is used for indicating at least one frequency domain discrete structure; the terminal determines the at least one frequency domain discrete structure according to the scheduling instruction, wherein a size value of the at least one frequency domain discrete structure belongs to a set comprising the size values of a plurality of frequency domain discrete structures, the set comprises the size value of a first frequency domain discrete structure and the size value of a second frequency domain discrete structure, or the set comprises the size value of the second frequency domain discrete structure, and the size value of the second frequency domain discrete structure is smaller than that of the first frequency domain discrete structure; and the terminal initiates uplink data transmission through utilization of the at least one frequency domain discrete structure.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to an uplink data transmission method and device. Background technique [0002] In a traditional Long Term Evolution (Long Term Evolution, LTE) system, data transmission can only be performed on licensed spectrum. With the increasing demand for wireless broadband data services, especially in some hot urban areas, the licensed spectrum may be difficult to meet the demand for traffic. To this end, the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) discusses the assisted access of authorized spectrum [0003] ((Licensed-Assisted Access, LAA) project proposal and unlicensed new wireless communication (New-radiounlicensed, NR-U) project proposal, to extend the LTE platform and NR platform to the unlicensed (Unlicensed) spectrum to meet the growing business quantity demand. [0004] In the Unlicensed frequency band, there are two important ...
