Abstract: An OFDM symbol generation method and a communication device are provided. The method includes: generating a target sequence based on a PTRS bit sequence, wherein the target sequence includes a symbol sequence generated by inserting the PTRS bit sequence into a data bit sequence and performing modulation, a symbol sequence generated by inserting a modulated symbol sequence of the PTRS bit sequence into a modulated symbol sequence of the data bit sequence and performing phase-rotation, or a symbol sequence generated by inserting a PTRS symbol sequence into a data symbol sequence, the PTRS symbol sequence is generated by modulating the PTRS bit sequence according to an index of a PTRS bit, the data symbol sequence is generated by modulating the data bit sequence according to an index of a data bit; and generating the OFDM symbol based on the target sequence.

Abstract: Embodiments of the present disclosure provide a transmission method, a terminal, a network device, and a computer-readable storage medium. The transmission method may be performed by a terminal or a network device. The transmission method performed by the terminal includes sending at least one piece of control information by using a target uplink channel, where each piece of control information corresponds to Transmission Reception Point (TRP) identifier information, the TRP identifier information is used to determine a target TRP corresponding to the control information, and the target TRP is one TRP in multi-TRP transmission.

Abstract: A method for transmitting a PTRS, a terminal, and a network device are disclosed in this disclosure. The method includes: acquiring target DMRS ports corresponding to two PTRS ports respectively in a scenario where a terminal performs non-codebook based uplink transmission by using a CP-OFDM waveform; and transmitting corresponding PTRSs to a network device by using respective target DMRS ports.

Abstract: The present disclosure provides sounding reference signal transmission and configuration methods, user equipment, and a network side device. The method for sounding reference signal (SRS) transmission includes receiving uplink resources of at least one cell from a network side device, where the uplink resources of each of the at least one cell comprise one or more SRS resource sets. The method further includes selecting, according to a predefined rule, at least one SRS resource set of each of the at least one cell for sending, when in a scenario in which an SRS switches between carriers for sending, where the scenario is configured by the network side device.
