Abstract: The present disclosure relates to signal transmission methods and apparatus. One example method includes receiving, by a terminal device, modulation and coding scheme (MCS) information sent by a network device, determining a modulation order used by the terminal device for data transmission, where the modulation order is determined based on the MCS information sent by the network device, information about a waveform used by the terminal device, and a preset correspondence between an MCS index and a modulation order, and transmitting data based on the determined modulation order.

Abstract: A control method for performing a multi-table join operation and a corresponding apparatus are disclosed. Fields in a table whose fields participating in a theta join operation and used in the query statement meet a first preset condition are decomposed, to obtain a plurality of first field groups, so that the theta join operation can be implemented in steps in a form of the plurality of field groups. This can reduce a data amount of Cartesian product calculation during one join operation, greatly reduce network transmission overheads, computing overheads, and memory overheads, and improve execution efficiency.

Abstract: This application provides a communication method, a terminal, and a network device. The communication method includes: repeating, by a first terminal, to-be-transmitted uplink control information for N times to obtain a first data segment, where N is a positive integer; determining, by the first terminal, an orthogonal cover code based on N; multiplying, by the first terminal, the first data segment by the orthogonal cover code to obtain a second data segment; and sending, by the first terminal, the second data segment. By using the communication method, the terminal, and the network device provided in this application, frequency diversity gains of the uplink control information can be increased, transmission flexibility of the uplink control information can be improved, and resource utilization can be increased.

Abstract: A reference signal sending method and a communications device are provided. The reference signal sending method includes: generating, by a first device, a tracking reference signal, where the tracking reference signal corresponds to a Demodulation Reference Signal (DMRS) port that is used by the first device when the first device sends data to a second device; mapping, by the first device, the tracking reference signal to a time-frequency resource that is used by the first device when the first device sends the data to the second device through the DMRS port, where the tracking reference signal is mapped to at least two modulation symbols on a same frequency resource in one transmission slot; and sending, by the first device, the tracking reference signal mapped to the time-frequency resource to the second device.

Abstract: A method for monitoring paging message, a method for sending indication information, a device, and a system are provided, and relate to the field of communications technologies. The method includes: receiving, by a terminal device, paging occasion configuration information sent by a network device, and monitoring, based on N time domain resources, a paging message sent by the network device. The paging occasion configuration information indicates the N time domain resources in a paging occasion, and N is a positive integer greater than or equal to 1. In this technical solution, the network device can indicate, to the terminal device, the time domain resource that is in the paging occasion and that is used to monitor the paging message.
