Embodiment 1

[0080] See figure 1 , an embodiment of the present invention provides a method for determining a CSI modulation order, which can be applied to a terminal. The implementation process of the method can be described as follows:

[0081] S101: The terminal receives the downlink control information DCI sent by the base station, where the DCI includes a first information field, the first information field is used to indicate the modulation order of the channel state information CSI, and the modulation order indicates the modulation mode of the CSI;

[0082] S102: Based on the DCI, the terminal sends CSI to the base station in a modulation manner indicated by the first information field.

[0083] In S101, the terminal receives the DCI sent by the base station, wherein the DCI includes a first information field, for example, assuming that the DCI has 10 bits, 2 bits of which can be defined as the first information field in the embodiment of the present invention, and the first informa...

Embodiment 2

[0136] See figure 2 , based on the same inventive concept, an embodiment of the present invention provides a method for determining a CSI modulation order, which can be applied to a base station. Among them, the implementation process of the method can be described as follows:

[0137] S201: The base station sends downlink control information DCI to the terminal, where the DCI includes a first information field, the first information field is used to indicate the modulation order of the channel state information CSI, and the modulation order indicates the modulation mode of the CSI;

[0138] S202: The base station receives, based on the DCI, the CSI sent by the terminal in a modulation manner indicated by the first information field.

[0139]In a possible implementation, the first information field is any one or at least two of the redundancy RV information field, the hybrid automatic repeat request HARQ process number information field and the new data indication NDI inform...

Embodiment 3

[0152] See image 3 , based on the same inventive concept, an embodiment of the present invention provides a terminal, including:

[0153] The receiving module 31 is configured to receive the downlink control information DCI sent by the base station, wherein the DCI includes a first information field, and the first information field is used to indicate the modulation order of the channel state information CSI, and the modulation order Indicates the modulation mode of the CSI;

[0154] The sending module 32 is configured to send the CSI to the base station based on the DCI in a modulation manner indicated by the first information field.

[0155] In a possible implementation, the first information field is any one or at least two of the redundancy RV information field, the hybrid automatic repeat request HARQ process number information field and the new data indication NDI information field combination.

[0156] In a possible implementation manner, if the first information fi...

Abstract

The embodiment of the invention provides a method for determining a CSI modulation order, a terminal and a base station, which are used for solving the technical problem that the method for determining the CSI modulation order in an existing communication system is not suitable for an NR communication system. The terminal receives downlink control information DCI sent by the base station, whereinthe DCI comprises a first information domain used for indicating the modulation order of the channel state information CSI, wherein the modulation order indicates the modulation mode of the CSI, the terminal sends the CSI to the base station in the modulation mode indicated by the first information domain based on the DCI, the modulation order of the CSI is determined through the first informationdomain in the DCI, and the terminal can support the transmission of the CSI in the PUSCH in the NR and does not contain the UL-. And a higher-order modulation mode is used during SCH.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method for determining a CSI modulation order, a terminal and a base station. Background technique [0002] In the long term evolution (Long Term Evolution, LTE) wireless communication system, the aperiodic channel state information (Channel State Information, CSI) is transmitted through the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), and the eNodeB base station schedules the downlink Control information (Downlink Control Information, DCI) triggers a user equipment (User Equipment, UE) to report aperiodic CSI. There is an information field in the DCI for scheduling uplink data to trigger aperiodic CSI reporting. When the information field indicates that the UE needs to report aperiodic CSI, the UE reports aperiodic CSI through PUSCH at a predefined position. [0003] In the LTE system, control information (including Hybrid Automatic...
