Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for a UE to determine whether to maintain or remove a radio frequency (RF) path from a set of candidate paths considered for transmit antenna switch diversity (ASDIV). The determination allows the UE to avoid signal loss or degradation in coexisting networks at similar frequency ranges. For example, ASDIV allows two or more antennas to form different input and output ports to establish different RF paths. Coexistent networks, such as wireless wide-area-network (WWAN) and wireless local-area-network (WLAN) may utilize different RF paths to optimize reliability and efficiency. The overlapping of the bands may cause signal attenuation or degradation from at least one of the networks. The present disclosure provides techniques for detecting signal attenuation at least partially caused by overlapping bands and removing an associated RF path to avoid such signal loss or attenuation.

A corresponding entity, computer programs and computer program products are also provided.
