摘要： This application provides a sequence-based signal processing method and apparatus. A sequence used for sending a signal on a PUSCH is determined. The sequence is a sequence {xn} including N elements, xn is an element in the sequence {xn}, and the determined sequence {xn} is a sequence satisfying a preset condition. Then, a first signal is generated and sent. By using the determined sequence, when a signal is sent on the PUSCH, relatively good sequence frequency domain flatness can be maintained, and a relatively low PAPR value and a relatively low cross-correlation between sequences can be maintained, thereby satisfying a communications application environment in which a signal is sent on the PUSCH, especially an NR system scenario or an NR similar scenario.

摘要： A communication method and apparatus are provided. LTE may obtain first information, where the first information is used for scheduling the UE for performing first transmission on a first uplink carrier, the first transmission is N-port transmission, and N is a positive integer. The UE may further perform the first transmission on the first uplink carrier, where when the first transmission is performed, a quantity of ports supported by the UE for uplink transmission on the first uplink carrier is M, and M is determined based on second information of at least one uplink carrier of the UE. This helps a base station and the UE have a consistent understanding of a state after the UE performs radio frequency chain switching each time, and can improve uplink transmission performance.

摘要： A signal sending method, a signal receiving method, and a device are provided. A part that is of a first signal and that is carried on the k th subcarrier in the i th subcarrier group in N subcarrier groups is x i,n id (k), and a sequence (s i,n id (k)} related to x i,n id (k) is one of enumerated sequences. The enumerated sequences are sequences with relatively good cross-correlation. Therefore, for two subcarrier groups, provided that selected {s i,n id (k)} is two of the enumerated sequences, cross-correlation between signals carried in the two subcarrier groups can be ensured to be relatively good, thereby reducing interference between the signals and improving channel estimation performance.

摘要： This application provides a sequence-based signal processing method and apparatus. The signal processing method includes: determining a sequence { x n } including N elements, where N is equal to 18, and the sequence { x n } satisfies a preset condition; generating a first signal based on the sequence { x n }; and sending the first signal. The sequence { x n } may satisfy a condition in which frequency domain flatness of a sequence is relatively good and a PAPR value is relatively small, so that when the first signal is a reference signal of a signal carried on a PUSCH, the relatively good frequency domain flatness of the sequence, and the relatively small PAPR value may be maintained for the sent first signal. Therefore, a requirement of a communication application environment in which the reference signal is sent can be met.
