Research on uplink sum-rate maximization for STAR-RIS assisted batteryless IoT: SDMA versus NOMA

To address the limitations of half-space coverage, low information transmission efficiency of RIS assisted batteryless IoT, a STAR-RIS assisted transmission scheme was proposed. Specifically, a STAR-RIS was deployed between the batteryless device (BD) and the access point, facilitating the uplink in...
