Description

Analog decoding and transmission for semantic communications Technical Field The following relates to wireless communications, including analog decoding and transmission for semantic communications. Background Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be able to support communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems, such as Long Term Evolution (LTE) systems, LTE-advanced (LTE-a) systems, or LTE-a Pro systems, and fifth generation (5G) systems, which may be referred to as New Radio (NR) systems. These systems may employ techniques such as Code Division Multiple Access (CDMA), time Division Multiple Access (TDMA), frequency Division Multiple Access (FDMA), orthogonal FDMA (OFDMA), or discrete fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple-access communication system may include one or more base stations, each supporting wireless communication for communication devices, which may be referred to as User Equipment (UEs). Disclosure of Invention The described technology relates to improved methods, systems, devices, and apparatus supporting analog decoding and transmission for semantic communications. For example, the described techniques allow a transmitting device to perform encoding of an analog signal based on an analog coding scheme. In some examples, the analog coding scheme may include a mapping function, which may be based on a mapping parameter (e.g., Δ), and a shaping function, which may be based on a shaping parameter (e.g., α). The mapping function may be used to map an input signal having a first dimension to an output signal having a second dimension different from the first dimension. In some examples, the mapping function may involve mapping the input signal based on an archimedes spiral. The shaping function may be used to shape the input signal to control the strength, variance, or both of the transmitted signal. In some examples, the transmitting device may transmit a message indicating the mapping parameter and the shaping parameter to a receiving device, which may decode a transmission including the analog signal based on the shaping parameter and the mapping parameter. Thus, the transmitting apparatus and the receiving apparatus can communicate using transmission based on analog signals. A method for wireless communication by a first device is described.
