Abstract: This disclosure provides techniques for managing antenna sharing on a multi-mode wireless device between coexisting cellular and WLAN modems operating on the same band. One of the modems can communicate a WLAN scanning parameter to another one of the modems, and the distribution of shared antennas between the cellular modem and the WLAN modem may be modified based at least in part on the communicated scanning parameter to accommodate a WLAN scan on channels in the shared band. The distribution of the shared antennas between the modems for the WLAN scan may additionally or alternatively be selected based at least in part on the source of a detected WLAN scanning trigger (e.g., whether the scan is triggered by an application of the wireless device or the WLAN modem of the wireless device).
