Abstract: This application provides a physical broadcast channel sending/receiving method and an apparatus. In the method, after receiving two broadcast channel signals on two corresponding physical broadcast channels at two time-frequency resource locations, the terminal device determines that information other than an offset of a corresponding time-frequency resource location is the same in two pieces of broadcast information carried in the two broadcast channel signals, obtains a time offset difference between the foregoing two time-frequency resource locations, and generates a scrambling sequence based on the time offset difference; and the terminal device separately descrambles the two broadcast channel signals based on the scrambling sequence and a preset scrambling sequence, thereby implementing joint decoding on the two broadcast channel signals, to obtain one piece of broadcast information.

Abstract: An acknowledgement information sending method and apparatus is provided. A network device determines and sends downlink scheduling signaling, where the downlink scheduling signaling is used to schedule first downlink data to a terminal, the first downlink data is downlink data corresponding to acknowledgement information fed back on a same uplink control channel, and the downlink scheduling signaling is used to determine a first threshold, a second threshold, or a third threshold. The terminal receives the downlink scheduling signaling sent by the network device, determines, based on the first threshold, the second threshold, or the third threshold, the acknowledgement information corresponding to the first downlink data, and sends the acknowledgement information corresponding to the first downlink data to the network device on the same uplink control channel.

Abstract: This application provides a sequence-based signal processing method and apparatus. 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} including N elements, and fn is an element in the sequence {fn}. The determined sequence {fn} is a sequence that meets a preset condition. Then the N elements in the sequence {fn} are respectively mapped to N subcarriers to generate and send a first signal. With the determined sequence, when the signal is sent by using the PUCCH, a low cross-correlation between sequences can be maintained, and a relatively small peak to average power ratio (PAPR) value and a relatively small and cubic metric (CM) value can be maintained. Therefore, a requirement in a communications application environment in which the signal is sent by using the PUCCH is met.

Abstract: This application provides a sequence-based signal processing method, a signal processing apparatus, a computer readable storage medium, and a computer program product. A sequence meeting a requirement in an environment in which a signal is sent by using a reference signal or a control channel is determined, where the sequence is a sequence {fn} including N elements, fn is an element in the sequence {fn}, and the determined sequence {fn} meets a preset condition; then the N elements in the sequence {fn} are mapped to N subcarriers respectively, to generate a first signal; and the first signal is sent. By using the foregoing determined sequence, weak cross-correlation between sequences can be maintained, and a relatively small PAPR value and a relatively small CM value of the reference signal or the control channel can be maintained, to meet a requirement in a communications application environment in which the signal is sent by using the reference signal or the control channel, particularly when a data signal on which π/2-BPSK modulation is performed is sent or frequency shaping is performed on the reference signal or the control channel.

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.
