Abstract

The invention discloses a CSI report transmission method, a terminal device and a network device. The method comprises the steps of in CSI reports needing to be transmitted on PUCCH resources of a component carrier, based on the priorities of the CSI reports, processing the collided CSI reports, wherein the number of the collided CSI reports is larger than two, and processing comprises reservationprocessing and discarding processing; and sending the corresponding CSI report on the PUCCH resource used by the CSI report reserved in the current component carrier. According to the embodiments ofthe present invention, more than two collided CSI reports are processed on the basis of the priorities of the CSI reports, thereby solving the problem of PUCCH resource competition of the CSI reportson member carriers.

Description

technical field [0001] The present invention relates to the communication field, in particular to a transmission method, terminal equipment and network equipment for a channel state information (Channel State Information, CSI) report. Background technique [0002] Channel state information (Channel State Information, CSI) report can be configured as: periodic CSI (Periodic CSI, P-CSI) report, semi-persistent CSI (Semi-Persistent, CSI SP-CSI) report or aperiodic CSI (Aperiodic CSI, AP -CSI) report. Wherein, P-CSI is only transmitted on PUCCH, SP-CSI can be transmitted on PUCCH or PUSCH, and AP-CSI is only transmitted on PUSCH. [0003] CSI report collision: when at least one Orthogonal Frequency Division Multiplexing (OFDM) symbol overlaps in the time domain for two CSI reports allocated on the same component carrier (Component Carrier, CC), then the two CSI reports collide. [0004] The solution in the prior art does not define a processing mechanism after more than two C...
