    Abstract: A communication method and apparatus are provided. UE 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.

    Abstract: 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.

    Abstract: A communication method and apparatus are provided. The method includes: A terminal device determines a first sequence whose length is Σi=0M−1 Ki, and sends the first sequence on M subcarrier groups, where an ith subcarrier group in the M subcarrier groups includes Ki subcarriers on a same symbol, i=0, 1, . . . , M−1, and frequency domain positions of subcarriers included in any two of the M subcarrier groups are different and belong to different symbols; and a sequence carried in each of the M subcarrier groups is a fragment of the first sequence, and fragments carried in any two subcarrier groups are different. According to the method, the terminal device sends the first sequence on the M subcarrier groups, so that interference between different terminal devices is small when channel estimation is performed by combining M symbols. This can effectively improve accuracy of channel estimation.

The method includes: The network side determines one physical channel area among multiple physical channel areas to be used by an ACK/NACK channel, and notifies the determined physical channel area to a User Equipment (UE) so as to enable the UE to determine a channel for receiving or sending ACK/NACK information in the determined physical channel area according to a mapping rule. Moreover, the network side may send or receive ACK/NACK information on the physical channel area that includes the ACK/NACK channel. The method and apparatus improve the utilization ratio and flexibility of the ACK/NACK channel, and reduce the probability of conflict generated by the ACK/NACK channel.

    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.
