Abstract: A terminal device determines a resource of a physical uplink control channel. The physical uplink control channel carries a first encoded bit sequence and a second encoded bit sequence, the first encoded bit sequence is corresponding to first uplink control information, and the second encoded bit sequence is corresponding to second uplink control information. The resource for the physical uplink control channel includes N orthogonal frequency division multiplexing (OFDM) symbol sets. The first encoded bit sequence is carried in an OFDM symbol included in j OFDM symbol sets, the j OFDM symbol sets are a part of or all of of the N OFDM symbol sets, where j is a positive integer less than or equal to N. The terminal device sends, on the resource for the physical uplink control channel, a signal that is generated based on the first uplink control information and the second uplink control information.

Abstract: This application discloses methods an apparatuses for sending and receiving uplink control information in the field of communications technology. In some implementations, a terminal device may receive first downlink control information (DCI) from a network device; determine, based on the received first DCI, that an uplink shared channel scheduled by using the first DCI is used to send only uplink control information (UCI); and send first UCI to the network device through the uplink shared channel scheduled by using the first DCI. In other words, the network device indicates to the terminal device by using DCI so that the terminal device can determine, based on an indication of the network device, whether the uplink shared channel scheduled by using the DCI is used to send only the UCI.

Abstract: A sequence-based signal processing method and apparatus are provided. A sequence meeting a requirement for sending a signal by using a physical uplink control channel (PUCCH) is determined. The sequence is a sequence {fn} consisting of 12 elements, fn represents an element in the sequence {fn}, and the determined sequence {fn} is a sequence meeting a preset condition. Then, the 12 elements in the sequence {fn} are respectively mapped to 12 subcarriers, to generate a first signal, and the first signal is sent. By using the determined sequence, when the signal is sent by using the PUCCH, a low correlation between sequences can be maintained, and a relatively small peak-to-average power ratio (PAPR) value and a relatively small cubic metric (CM) value can be maintained. Therefore, a requirement of a communication application environment in which the signal is sent by using the PUCCH is met.

Abstract: The present disclosure discloses an uplink retransmitted data sending method, apparatus, and system, and relates to the field of communications technologies. The method includes: receiving data transmitted on a same contention resource by different user equipments (UEs) that are in a same contention resource group; demodulating, based on a demodulation reference signal DMRS sequence carried in the data, the data sent by the UEs; and when demodulation of data sent by at least two UEs fails, scheduling, by using an uplink grant (UL-grant), the UEs whose data fails to be demodulated, to retransmit the data on a designated non-contention resource. This resolves a prior-art technical problem that uplink data retransmission fails, and improves uplink data retransmission efficiency.

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.
