Embodiment Construction

[0054] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0055] The basic time transmission unit in the system is a symbol, and 14 symbols form a time slot. The length of a time slot is 1 / 2k ms, where the value of k is a positive integer, corresponding to different subcarrier intervals, such as k=0, 1, 2, 3, 4, 5, 6, the corresponding subcarrier interval is 15kHz, 30kHz, 60kHz, 120kHz, 240kHz, 480kHz, 960k...

Abstract

The invention discloses a downlink continuous data transmission method, downlink control information comprises first information, and the first information is used for scheduling downlink data transmission in L continuous time slots; the first information is also used for indicating second information, and the second information identifies the position of a starting time slot of the L continuous time slots; and the first information is also used for indicating third information, and the third information identifies a time slot used for transmitting downlink data in the L continuous time slots. The invention further comprises equipment and a system applying the method. The problems that the time slot scheduling amount is large and the communication efficiency is low are solved.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a downlink continuous data transmission method, device and system. Background technique [0002] The 5G new air interface (NR) has completed two versions, R15 and R16. According to the current version, it supports up to 52.6GHz. According to the original vision of 5G, the design of 5G NR needs to support the frequency use of 100GHz. In higher frequency bands, it is necessary to consider supporting larger bandwidths while overcoming the adverse effects of large path losses. In order to better use the existing NR design at high frequencies, a series of enhancements to the existing NR design are required. [0003] The frequency band above 52.6GHz has a wider bandwidth than the lower frequency band, and there are a large number of unlicensed frequency bands. In view of these characteristics, it is necessary to consider adopting a larger subcarrier spac...
