Problems solved by technology

[0008] Embodiments of the present invention provide a channel state information report transmission method and a terminal to solve the problem that the CSI report is discarded when multiple PUCCH-based CSI reports collide, causing the network side to obtain the CSI report not in time or the CSI report to be missing.

Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] The related technologies of the present invention will be briefly described below.

[0029] When the PUCCH resources used by two CSI reports on the same carrier have at least one OFDM symbol overlapping in the time domain, the two CSI reports collide. Each CSI report corresponds to a priority, and the UE does not send some CSI reports with lower priorities when CSI report collisions occur or when uplink transmission resources are limited. For example: CSI priority is first determined according to rule 1, if the priorities obtained according to rule 1 are equal, then the priority is determined according to rule 2, and so on.

[0030] Rule 1: According to time domain behavior / channel type (AP-CSI>SP-CSI on PUSCH>SP-CSI on PUCCH>P-CSI);

Abstract

The invention provides a channel state information report transmission method and a terminal, and relates to the technical field of communication. The channel state information report transmission method comprises the following steps: obtaining an allocation rule of a channel state information CSI report transmitted on a PUCCH, the allocation rule being configured by network equipment or agreed bya protocol; when at least two CSI reports collide with each other, distributing a part of or all of the CSI reports with collision to a first CSI PUCCH according to the distribution rule; transmitting the CSI reports of which the part number or the whole number has collision, wherein the first CSI PUCCH is used for transmitting a part of or all of the CSI reports with collision. According to theembodiments of the present invention, the method is capable of correctly allocating a plurality of PUCCH-based CSI reports with collisions to at least one of a plurality of multi-CSI PUCCHs configuredby a network device according to an allocation rule, to solve the problem that the network side cannot obtain the CSI report timely or the CSI report is missing due to the fact that the CSI report isdiscarded during collision of multiple PUCCH-based CSI reports.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a transmission method and a terminal for a channel state information report. Background technique [0002] Typically, Channel State Information (CSI) reporting can be configured as follows: [0003] 1) Periodic CSI report (P-CSI): only transmitted on PUCCH; [0004] 2) Semi-persistent CSI report (SP-CSI): transmitted on PUCCH or PUSCH; [0005] 3) Aperiodic CSI report (AP-CSI): only transmitted on PUSCH. [0006] Priority regulation: when the PUCCH resources used by two CSI reports on the same carrier overlap at least one OFDM symbol in the time domain, then the two CSI reports collide. Each CSI report corresponds to a priority value, and the terminal does not send some CSI reports with high (or low) priority values ​​when CSI report collisions occur or uplink transmission resources are limited. [0007] It can be seen that, in the prior art, when multiple PUCCH-based ...
