Access point methods and apparatus relating to supporting coexistence of multiple receiver/transmitters in a device supporting one or more communications standards

Abstract

Methods and/or apparatus for reducing or avoiding (IDC) in-device coexistence problems in devices which support multiple communications protocols, e.g., WiFi and LTE, are described. In various embodiments a WiFi AP can request or require devices, e.g., STAs to report IDC information pertinent to the individual device. This is done by sending one or more trigger frames, e.g., as part of a multicast or unicast operation. Alternatively, devices can voluntarily report IDC information. The AP, e.g., WiFi AP, takes the IDC information it receives, e.g., from multiple devices, e.g., STAs, into account when scheduling UL resources to be used by the wireless devices. By taking into consideration the IDC information provided by STAs, IDC conflicts can be avoid even though a WiFi AP is scheduling resources for WiFi communication in devices which are also using resources for another communications standard, e.g., LTE, over which the AP does not have control.
