Abstract

The present invention provides a mobile communication uplink information scheduling method, terminal, network equipment and system, which solves the problem of avoiding using a dedicated field to distinguish the physical uplink shared channel type in the uplink scheduling grant. The method includes the following steps: the terminal device receives uplink scheduling grant information, the uplink scheduling grant information includes a channel state information request, a modulation and coding scheme index value, and a redundancy version index value; when the channel state information request indicates an aperiodic transmission In the case of channel state information, if the modulation and coding scheme index value is the first predetermined value and or the redundancy version index value is the second predetermined value, the physical uplink shared channel sent by the terminal device does not include the uplink shared channel. The terminal device may further identify at least one of the modulation order, target coding rate and spectral efficiency of the physical uplink shared channel by using the HARQ index value. The present invention also includes a terminal, network device and system for the method.

Description

technical field [0001] The present application relates to the field of mobile communications, and in particular, to a method, device and system for scheduling uplink information of mobile communications. Background technique [0002] In a new generation wireless communication (NR) system, the physical uplink shared channel (PUSCH) can carry the uplink shared channel (UL-SCH) and / or uplink control information (UCI) sent by the terminal equipment. The terminal device determines, according to the uplink scheduling grant (UL grant) information sent by the network device in the downlink control information (DCI), whether the sent physical uplink shared channel only includes the uplink shared channel, only includes the 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) acknowledgement messages, periodic channe...
