Abstract: This application provides a downlink information transmission method, apparatus, and a device. The method includes: encoding information into a plurality of transport blocks; determining a time-frequency resource used to send each transport block; sending downlink resource indication information to user equipment, where the downlink resource indication information indicates a time-frequency resource location occupied by an Mth transport block; and sending corresponding transport blocks on the time-frequency resources. The user equipment receives the transport blocks based on the downlink resource indication information and decodes the transport blocks to obtain the information, where the downlink resource indication information indicates a resource of only one transport block. A terminal device may determine a time-frequency resource location of another transport block based on a location parameter of the another transport block, and receive and decode the another transport block. Same information bits are carried in a plurality of transport blocks, thereby improving transmission reliability.

Abstract: This application provides an information transmission method and apparatus. A terminal receives downlink control information (DCI), wherein a format of the DCI corresponds to a time domain resource set, the time domain resource set comprises first time domain resource. The terminal determines the first time domain resource from the time domain resource set based on the format of the DCI and second information, wherein the second information is carried in the DCI, and the second information indicates the index of the first time domain resource in the time domain resource set. And the terminal performs information transmission on the first time domain resource and through a physical channel.

Abstract: Devices and methods are provided for receiving a first indication and a second indication, the first indication associated with a first set of transmission parameter information for a first repetition of data received in a Physical Downlink Shared Channel (PDSCH) and the second indication associated with a second set of transmission parameter information for a second repetition of data received in the PDSCH. Each set of transmission parameter information corresponds to a Quasi-Co-Location (QCL) information for the respective repetition of data. In addition, the method involves receiving a first PDSCH repetition and a second PDSCH repetition. A channel estimate can then be performed for the first PDSCH repetition based on the QCL information for the first PDSCH repetition and a channel estimate for the second PDSCH repetition based on the QCL information for the second PDSCH repetition.
