Embodiment Construction

[0039] 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.

[0040] The solution of the present invention distinguishes the different types of the scheduled physical uplink shared channel physical uplink shared channel through the combination of the aperiodic channel state information, the modulation and coding scheme and the specific state of the redundancy version in the uplink scheduling grant sent by the net...

Abstract

The invention provides a mobile communication uplink information scheduling method, a terminal, network equipment and a system, and solves the problem of distinguishing the type of a physical uplink shared channel by using a special field in uplink scheduling authorization. The method comprises the following steps that: terminal equipment receives uplink scheduling authorization information, wherein the uplink scheduling authorization information comprises a channel state information request, a modulation and coding scheme index value and a redundancy version index value; and when the channelstate information request indicates to send aperiodic channel state information, if the modulation and coding scheme index value is a first predetermined value and / or the redundancy version index value is a second predetermined value, the terminal device does not include the uplink shared channel in the sent physical uplink shared channel. And the terminal equipment can also identify at least oneof the modulation order, the target coding rate and the spectral efficiency of the physical uplink shared channel by using the hybrid automatic repeat process index value. The invention also comprisesa terminal, network equipment and a system for the method.

Description

technical field [0001] The present application relates to the field of mobile communication, and in particular to a method, device and system for scheduling uplink information of mobile communication. Background technique [0002] In a new generation wireless communication (NR) system, a Physical Uplink Shared Channel (PUSCH) may carry an Uplink Shared Channel (UL-SCH) and / or Uplink Control Information (UCI) sent by a terminal device. According to the uplink scheduling grant (UL grant) information sent by the network device in the downlink control information (DCI), the terminal device determines whether the sent physical uplink shared channel includes only the uplink shared channel, only aperiodic channel state information (A-CSI), or It includes both uplink shared channel and aperiodic channel state information. If the terminal device needs to send information such as hybrid automatic repeat request (HARQ) confirmation message, periodic channel status message and other in...
