Abstract: Provided are a method and device for sending control information and receiving control information. The method for sending control information comprises repeatedly sending control information within a scheduling period of the control information M times, wherein the scheduling period is the length of N radio frames, N and M are positive integers greater than 1, and N is greater than or equal to M. The disclosure solves the technical problem in the related art that control information cannot be correctly received in a low-coverage environment and thus a terminal cannot normally access a network, achieving the technical effect of accurately receiving the control information so as to ensure that the network can be accessed normally.

Abstract: The present disclosure describes methods, system, and devices for generating a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook feedback for at least one physical downlink shared channel (PDSCH) scheduled by a downlink control information (DCI). One method includes receiving, by a user equipment (UE), a radio resource control (RRC) parameter to configure an enhanced dynamic HARQ-ACK codebook feedback mode; receiving, by the UE, the DCI comprising a set of parameters to configure at least one PDSCH group comprising the at least one PDSCH; and transmitting, by the UE, a HARQ-ACK codebook feedback based on the set of parameters in the DCI and the at least one PDSCH group. Another method includes receiving, by the UE, the DCI comprising a bit field used for triggering a one-shot HARQ-ACK feedback mode; and transmitting, by the UE, a one-shot HARQ-ACK feedback based on a set of parameters in the DCI.

Abstract: Provided are a data transmission method and apparatus, and a storage medium. The data transmission method includes: performing, by a first communication terminal, a clear channel assessment on a target resource, where the target resource is a target time domain resource corresponding to a part of second data transmission suspended or punctured by a second communication terminal, and the first communication terminal and the second communication terminal satisfy a transmission multiplexing condition; and when a channel is determined to be in an idle state, transmitting, by the first communication terminal, first data on the channel.

Abstract: Provided are a method and apparatus for sending and receiving feedback information, and a storage medium. The method includes: receiving service data sent by a user equipment (UE); and sending downlink feedback indication (DFI) information corresponding to the service data to the UE. Where the DFI information includes a HARQ ACK/non-acknowledgement NACK indication, and the HARQ ACK/NACK indication is configured for indicating a decoding result of a transport block (TB) and/or a code block group (CBG) in the service data decoded by a base station.

Abstract: Techniques are described to feedback hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook. For example, a base station can send HARQ-ACK codebook information to a user equipment, schedule retransmission, and transmit a downlink feedback information (DFI) if the user equipment transmits a code block group (CBG) based autonomous transmission. Techniques are also described for a user equipment to improve the feedback HARQ-ACK efficiency for downlink physical downlink shared channel (PDSCH) transmission.
