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 disclosure provide a method for a transmission of uplink control information (UCI), such as hybrid automatic repeat request (HARQ) information. A base station sends first indication information to a user equipment (UE), to instruct the UE to dynamically determine the UCI according to the first indication information, and the base station allocates a physical uplink control channel (PUCCH) resource to the UE to transmit the UCI. The embodiments of the present disclosure may be used to implement a feedback of the UCI information in a carrier aggregation scenario, thereby improving performance of transmitting valid UCI information.

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.

Abstract: A control information sending method, receiving method, and device are provided. The control information sending method includes: determining a first subframe of a first radio frame on a first carrier, where the first subframe includes a control region; sending control information in the control region of the first subframe of the first radio frame to a user equipment, where the control information includes a PDCCH; and sending an ePDCCH in a second subframe of the first radio frame to the user equipment. According to the embodiments of the present invention, when control information borne on an ePDCCH cannot be sent in a first radio frame, a PDCCH can still be sent to a user equipment through a control region in a first subframe, thereby achieving purposes of performing uplink/downlink scheduling for the user equipment and downlink feedback for uplink data of the user equipment.
