Abstract: A device includes a processor and a non-transitory computer-readable storage medium coupled to the processor. The non-transitory computer-readable storage medium has programming instructions for being executed by the processor. The programming instructions, when executed by the processor, cause the device to receive configuration information sent by an access network side communications apparatus. The configuration information includes identification information of at least one cell. The device is also caused to detect first indication information sent by the access network side communications apparatus by using a length of a first time as a granularity. The first indication information indicates a transmission structure corresponding to one or more time units included in a second time of the at least one cell identified by the identification information. The length of the first time is different from a length of the second time.

Abstract: This application provides a method for transmitting hybrid automatic repeat request HARQ feedback information and a communications apparatus. A terminal device receives downlink data channels. Each of the downlink data channels has a corresponding transmission parameter group, and at least two downlink data channels correspond to different transmission parameter groups. The terminal device determines a first transmission resource based on first information including the transmission parameter groups, and sends, on the first transmission resource, HARQ feedback information corresponding to the downlink data channels, so that a plurality of pieces of HARQ feedback information can be smoothly fed back. This helps improve service transmission reliability.

Abstract: Embodiments of this application provide a buffer status report (BSR) sending method, a terminal device, and a network device. The method includes: determining a first resource configured for a first channel; adding, a first cyclic redundancy check (CRC) to a BSR; and sending a second channel on the first resource, or sending the first channel and a second channel on the first resource, where the second channel is used to carry the BSR to which the first CRC is added. Based on the embodiments of this application, the terminal device independently adds the first CRC to the BSR, and sends the second channel carrying the BSR to a network device, so that the network device learns arrival of data corresponding to the second channel at the terminal device. Therefore, the network device can pre-configure a resource for the data, thereby reducing a transmission latency of the data.

Abstract: Embodiments of the present invention provide a method for transmitting uplink control information and an apparatus, applicable to a multi-carrier system. A user terminal receives physical layer signaling from a network device, where the physical layer signaling includes first indication information. The user terminal determines, according to the first indication information, a bit quantity of periodic CSI that can be sent on a channel resource or a piece quantity of periodic CSI that can be sent on a channel resource. The user terminal determines, according to the bit quantity or the piece quantity of the periodic CSI that can be sent, to-be-sent periodic CSI from periodic CSI corresponding to multiple downlink carriers. The user terminal sends HARQ-ACK information and the to-be-sent periodic CSI on the channel resource.
