Abstract: The present invention provides an uplink data sending method. The method includes: receiving, by a terminal device, scheduling signaling in at least one downlink time interval in a downlink time interval set, where the scheduling signaling is used to schedule uplink data, and any downlink time interval in the downlink time interval set belongs to a downlink subframe n; determining, by the terminal device, an uplink time interval corresponding to the at least one downlink time interval, where the any downlink time interval in the downlink time interval set is corresponding to the determined uplink time interval, the determined uplink time interval belongs to an uplink subframe n+k, and k is equal to 0, 1, 2, or 3; and sending, by the terminal device, the uplink data in the determined uplink time interval. In the foregoing solution, a latency from receiving scheduling information to sending uplink data can be reduced.

Abstract: Embodiments of the present invention provide an uplink control information sending method, an uplink control information receiving method, an apparatus, and a system. The method includes: receiving, by a terminal device, channel indication information from an access network device on a physical control channel; determining the channel resource set that is of N channel resource sets and that matches a type or a size of the UCI as a first channel resource set; determining a channel resource that is in the first channel resource set and that is indicated by the channel indication information; and sending uplink control information UCI to the access network device on the channel resource. A quantity of bits that need to be added to the channel indication information in the embodiments of the present invention is less than that in the prior art.

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.

Abstract: A method may include: dividing, by a sending device into k code blocks CBs, a TB into which a cyclic redundancy check bit is loaded; then separately performing channel coding on the k CBs, to obtain a bit sequence Sj, where j=1, 2, . . . , and k, and a set S={S1, S2, . . . , Sk}; and mapping, by the sending device, some or all bit sequences in all elements in S to transmission resources in N basic transmission time units, where some or all bit sequences in the Sj are mapped to transmission resources in Mj basic transmission time units, and a last bit in the Sj mapped to an mth basic transmission time unit in the Mj basic transmission time units and a first bit in the Sj mapped to an (m×1)th basic transmission time unit are contiguous in the Sj.

Abstract: The present disclosure relates to a terminal device, in which a processing module selects one or more normal carriers or special carriers from a first carrier set for an uplink subframe, where the first carrier set includes all carriers in carrier aggregation that are used by the terminal device to send a first uplink subframe; and a sending module cancels sending of the uplink subframe on one or more carriers, where the special carrier is a carrier on which the terminal device sends neither uplink data nor uplink control information in uplink, and the normal carrier is a carrier that is used by the terminal device to send uplink data and/or uplink control information. An uplink subframe on some carriers is rejected, thereby resolving a problem that information such as a downlink channel characteristic of a carrier cannot be obtained when no uplink reference signal is sent on the carrier.

Abstract: A terminal receives downlink scheduling information of a downlink subframe F(i, j), where a set M of preconfigured downlink subframes in which the downlink subframe F(i, j) is located is divided into N subsets of preconfigured downlink subframes, a bit quantity of a hybrid automatic repeat request-acknowledgement HARQ-ACK that needs to be fed back for each downlink subframe in one subset of preconfigured downlink subframes is a predetermined value, and bit quantities of HARQ-ACKs that need to be fed back for any downlink subframes in different subsets of preconfigured downlink subframes are different. The terminal generates a HARQ-ACK codebook according to a receiving status of downlink data. And the terminal generates uplink control information after encoding the HARQ-ACK codebook; and a sending module sends the uplink control information.
