Abstract: This application discloses a signal transmission method, including: obtaining, by a terminal device, to-be-transmitted data, uplink control information, and a demodulation reference signal; mapping the to-be-transmitted data, the uplink control information, and the demodulation reference signal to generate multiplexed symbols. The multiplexed symbols include DFT-s-OFDM symbols or OFDM symbols. N first multiplexed symbols are located on one side or two sides of a second multiplexed symbol. A location relationship between each of the N first multiplexed symbols and the second multiplexed symbol satisfies a mapping condition. N is an integer greater than or equal to 1. The first multiplexed symbol is a multiplexed symbol to which the uplink control information is mapped, and the second multiplexed symbol is a multiplexed symbol to which the demodulation reference signal is mapped.

Abstract: This application provides a photoelectric amplification circuit and a signal processing method. The photoelectric amplification circuit includes a first photodiode and a second photodiode that are connected in parallel. A Doherty circuit structure is used, so that power supply efficiency of the photodiode in a back-off state can be improved. In addition, an impedance modulation unit is used, to implement dynamic load conversion from a back-off point to a maximum output point. This helps maintain high output efficiency of the first photodiode and the second photodiode in an interval between the maximum power point and the back-off point.

Abstract: Example memory access popularity statistics methods and apparatus are described. One example method includes determining a first address based on an access request. The access request indicates an operation performed on a memory of a computer device by an application program run by at least one processor in the computer device. Statistics about access frequency of accessing a data block stored at the first address is collected. An access popularity of the data block is determined based on the access frequency.
