Description

Communication method, electronic device, program product, and storage medium Technical Field The present application relates to the field of communications technologies, and in particular, to a communications method, an electronic device, a program product, and a storage medium. Background Since conventional terrestrial networks cannot provide seamless coverage, particularly in places where base stations cannot be deployed in the sea, desert, air, etc., non-terrestrial networks (Non Terrestrial Network, NTN) are considered an important aspect of future wireless communication technology developments, in which NTN systems radio communication devices on the ground communicate using satellites as relays. In NTN systems, most users operate in a low Signal-to-Noise Ratio (SNR) environment, and in order to ensure closure of a link, network devices employ a retransmission technique, which can help low SNR users successfully transmit data. When the Physical Uplink shared channel (Physical Uplink SHARED CHANNEL, PUSCH) and the channel Sounding reference signal (Sounding REFERENCE SIGNAL, SRS) sent by the terminal device to the network device overlap in the time domain, uplink transmission performance is reduced. Disclosure of Invention The application provides a communication method, an electronic device, a program product and a storage medium, and aims to improve uplink transmission performance. In order to achieve the above object, the present application provides the following technical solutions: In a first aspect, an embodiment of the present application provides a communication method, where the method may be performed by a terminal device, or may also be performed by a component (such as a circuit, a chip, or a chip system) configured in the terminal device, or may be implemented by a logic module or software that can implement all or part of the functions of the terminal device. For example, the method is applied to the first terminal device, and the present application is not limited thereto. The following description will take a terminal device as an example. The method comprises the following steps: Determining a first reference signal and first data carried by a first data channel; the first reference signal and/or the first data is transmitted based on an orthogonal cover code OCC. In the above scheme, the first terminal device may determine the first reference signal and the first data, and send the first reference signal and/or the first data through the OCC, and because multiple terminal devices can be multiplexed on the same time-frequency resource through the OCC, the first reference signal and the first data can be prevented from having time domain overlapping through the OCC, which improves the resource utilization rate and improves the uplink transmission performance. In some possible implementations, the transmitting the first reference signal and/or the first data based on the orthogonal cover code OCC includes: The first reference signal and the first data are transmitted on a first slot included in the period of the OCC, and the first reference signal and the first data are transmitted on a second slot included in the period of the OCC. In the scheme, the same first reference signal can be sent on a plurality of time slots on the period of the OCC, and the transmission contents of all the time slots in the period of the OCC are consistent, so that the requirement of the orthogonality of the OCC can be met, the resource utilization rate is improved, and the uplink transmission performance is improved. In some possible implementations, the transmitting the first reference signal and/or the first data based on the orthogonal cover code OCC includes: transmitting a first reference sub-signal and the first data based on the OCC; The first reference sub-signal is determined according to the first reference signal and a first parameter, the first parameter is used for reducing the number of time domain symbols of the first reference signal, and the value of the first parameter is smaller than or equal to the OCC length. In the above scheme, the first parameter is adopted to reduce the number of time domain symbols of the first reference signal, so that the first terminal device can reduce the length of the transmitted reference signal, improve the resource utilization rate and improve the uplink transmission performance by transmitting the first reference sub-signal based on the OCC rather than transmitting the first reference signal based on the OCC. In some possible implementations, the transmitting the first reference signal and/or the first data based on the orthogonal cover code OCC includes: Transmitting the first reference signal based on the OCC, and not transmitting the first data based on the OCC; Or alternatively And transmitting the first data based on the OCC, and not transmitting the first reference signal based on the OCC. In the above scheme, the first terminal device discards any on
