Terminal apparatus for notifying interference suppression capability
The granted patent US12063675B2 outlines a terminal apparatus and a base station apparatus designed to enhance communication efficiency in wireless networks. The terminal apparatus includes a notification unit that informs the base station whether it can suppress interference from an uplink signal on a downlink signal. This capability is crucial for optimizing resource allocation, as the base station can adjust its wireless resource assignments based on the terminal's interference suppression capability. Additionally, the terminal can provide information about propagation loss when interacting with other terminal apparatuses, which further aids in resource management.
The base station apparatus is equipped with an obtaining unit that receives the terminal's interference capability information and a subsequent executing unit that allocates wireless resources accordingly. Depending on whether the terminal can suppress interference, the base station may allocate the same or different resources for receiving and transmitting signals. The patent also describes methods for both terminal and base station apparatuses to execute these functions, as well as non-transitory computer-readable storage mediums that store programs to facilitate these operations. Overall, the patent emphasizes a structured approach to managing wireless resources, potentially leading to improved communication performance in multi-user environments.
