Description

TECHNOLOGICAL FIELD Various aspects of the present disclosure relate generally to techniques for non-primary channel access (NPCA) and, more particularly, to a framework for concurrent reception for NPCA. BACKGROUND Wireless communication networks, such as wireless fidelity (Wi-Fi) networks, may support latency-sensitive applications at Wi-Fi stations (STAs). Some such applications include virtual reality (VR) applications, mixed reality (MR) applications, and augmented reality (XR) applications. In some cases, reliability and non-deterministic channel access, such as for wideband transmissions, may constrain a performance of latency-sensitive applications.
