Abstract: A terminal device receives first information including an acknowledgment resource indicator (ARI), and determines, based on the ARI, a first uplink control channel (PUCCH) resource in a PUCCH resource set corresponding to a payload size of a hybrid automatic repeat request acknowledgment (HARQ-ACK). In a case that the first PUCCH resource and a second PUCCH resource partially overlap in terms of time; or the first PUCCH resource and a second PUCCH resource configured for CSI do not overlap in terms of time, and the first PUCCH resource and the second PUCCH resource each partially overlap at least one third PUCCH resource configured for at least one positive scheduling request (SR) in terms of time, the terminal device determines, based on the ARI, a fourth PUCCH resource in a second PUCCH resource set corresponding to a total payload size for sending the HARQ-ACK, CSI, and at least one SR status.

Abstract: This application relates to the field of wireless communications technologies, and in particular, to a data processing method, apparatus, and system. This application provides a data processing method. A transmit device uses a sequence to carry data and a reference signal. The transmit device carries the two channels of data on an odd element and an even element of the sequence, respectively. The transmit device successively maps the sequence that carries the two channels of data to allocated subcarriers, and then sends the data in an orthogonal frequency division multiplexing (OFDM) manner. This application is intended to decrease cubic metric (CM)/peak-to-average ratio of a transmitted signal of an orthogonal frequency division multiplexing OFDM system through sequence design and mapping of the two channels of data to subcarriers, thereby improving link quality of an entire transmission system.

Abstract: A slot type indication method and an apparatus and a slot type determining method and an apparatus are provided. Under the slot type indication method, a first indication information can be generated by a network device. The first indication information indicates a slot type of a first slot. When the slot type of the first slot is a predefined type, the first indication information further indicates whether a second slot is an uplink-only slot, and the first slot is a slot that includes a downlink control channel. The first indication information can be sent, by the network device, by using the downlink control channel of the first slot.

Abstract: Embodiments of the present disclosure provide example uplink control information transmission methods, terminal devices, base stations, and systems. An example transmission method includes the following steps: First, the terminal device determines an information bit sequence of to-be-transmitted uplink control information. Then, the terminal device determines a first sequence according to the information bit sequence, where the first sequence is a linear-phase complex exponential sequence. Finally, the terminal device sends the to-be-transmitted uplink control information to the base station by using an uplink control channel, where the uplink control channel occupies N symbols, N is a positive integer, a signal carried on a symbol l of the N symbols is directly proportional to a product of the first sequence and a second sequence, and the second sequence is a cyclic shift sequence.

Abstract: Embodiments of the present disclosure provide, among other implementations, sequence determining methods. One example method provides a sequence group, and one sequence group number is corresponding to at least two sequences, where one sequence is used for mapping to consecutive subcarriers, and at least one other sequence is used for mapping to equally-spaced subcarriers. In some embodiments of the present disclosure, as high as possible cross-correlation between a sending signal obtained after equally-spaced mapping is performed on a sequence in a sequence group can be determined, and a sending signal obtained after continuous mapping is performed on another sequence in the group.
