    Abstract: The embodiments of the present invention provide a feedback information transmission method and a terminal device, which relate to the field of communications technologies and are used to resolve the problem of how a terminal device sends feedback information in a multi-TRP communications system. The method is applied to a terminal device and includes: in the case of receiving at least two PDCCHs sent by at least two TRPs or different antenna panels of one TRP, determining a target PUCCH resource, and sending target feedback information through the target PUCCH resource, where the target feedback information is feedback information of each PDSCH scheduled by the at least two PDCCHs. The embodiments of the present invention are used for the transmission of feedback information.

    Abstract: The present application discloses a method of channel estimation based on precoding granularity of control resource set, which is applied to a user equipment with control resource set (CORESET) configured in a non-RRC manner. The method includes: determining precoding granularity according to a determination mode among a plurality of determination modes; performing channel estimation according to the precoding granularity. The plurality of determination modes includes: determining the precoding granularity according to a resource element group (REG) bindle size in frequency domain, determining the precoding granularity according to the number of consecutive resource blocks (RBs) in frequency domain of the CORESET, and determining the precoding granularity according to network configuration information. According to the present application, the precoding granularity of the control resource set configured in a non-RRC manner can be determined, so that the user equipment can determine the precoding granularity before the RRC connection is established, and then perform channel estimation.

    Abstract: The present disclosure provides a hybrid automatic repeat request-acknowledgement (HARQ-ACK) feedback position determining method and a communications device. The HARQ-ACK feedback position determining method includes: when a repetition scheme of a physical downlink shared channel (PDSCH) in one slot is configured or indicated, determining at least one candidate PDSCH reception occasion based on a start and length indicator (SLIV) of a time domain resource allocation (TDRA); and determining, based on the first PDSCH scheduled by using downlink control information (DCI) and the at least one candidate PDSCH reception occasion, a feedback position of an HARQ-ACK corresponding to a first PDSCH in a preset HARQ-ACK codebook, where the first PDSCH is transmitted for one or more times.

    Abstract: An information transmission method and a terminal are disclosed. The method includes: when resource overlapping occurs between a first CSI report and a second CSI report, performing the following operations: if a physical channel corresponding to the first CSI report is a physical uplink control channel PUCCH, a physical channel corresponding to the second CSI report is a PUCCH, and a multi-CSI-physical uplink control channel-resource list is configured, transmitting the CSI reports with overlapping resources based on a resource in the multi-CSI-physical uplink control channel-resource list; and/or, if a physical channel corresponding to the first CSI report is a PUCCH, a physical channel corresponding to the second CSI report is a physical uplink shared channel PUSCH, and the PUCCH and the PUSCH are transmitted on different carriers, discarding the PUCCH and the CSI report carried on the PUCCH, and transmitting the PUSCH and the CSI report carried on the PUSCH.
