Abstract: A timing method for time division duplex communication, an uplink/downlink data scheduling method, a base station, and user equipment are provided. By determining whether grouping needs to be performed on uplink/downlink short transmission time intervals, it is determined, for different grouping requirements, whether addition of indication information to control signaling is required to indicate to user equipment an uplink short transmission time interval sequence number in an uplink short transmission time interval group for uplink data transmission or feedback to downlink data scheduling. Alternatively, addition of indication information to control signaling is not required, and uplink data transmission or feedback to downlink data scheduling is performed in an uplink short transmission time interval determined according to a default rule.

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.

Abstract: Embodiments of this application provide a storage node, including a network chip and a storage device. By opening a memory of the storage device to the network chip, a table resource required by the network chip to maintain each connection in a related technology is offloaded to the memory of the storage device. The network chip is configured to generate a command based on an access request of a client, store the command in a first table in the memory of the storage device, and execute the command in the first table to access the storage device. The storage device is configured to store data accessed by using the command. The present invention enables the network chip to support a larger quantity of connections in limited storage space of the network chip.

Abstract: Example synchronization signal sending and receiving methods and apparatus are described. In one example method, a terminal device determines a target frequency resource. A frequency domain position of the target frequency resource is determined based on a frequency domain position offset and a frequency interval of synchronization channels. The terminal device receives a synchronization signal by using the target frequency resource.

Abstract: A communication method, a device, and an apparatus are provided. A network device determines N configuration parameter sets configured for a terminal device, where each of the N configuration parameter sets includes a parameter for detecting a candidate downlink control channel, and N is an integer greater than or equal to 2. The network device sends information about the N configuration parameter sets to the terminal device. Each of the N configuration parameter sets includes at least one of the following parameters: a bandwidth part, a search space parameter, a candidate downlink control channel detection period, a control resource set parameter, or a time domain resource set corresponding to the candidate downlink control channel. The network device may configure the N configuration parameter sets for the terminal device.

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: This application provides a synchronization signal sending method and receiving method, and an apparatus. In the method, a base station determines a frequency domain position of a target frequency resource based on a frequency interval of synchronization channels, wherein the frequency interval of synchronization channels is 2m times a predefined frequency resource of a physical resource block, and m is a preset nonnegative integer. The base station sends a synchronization signal by using the target frequency resource.

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.
