Abstract
Techniques for controlling or managing uplink access of a UE to a base station using unlicensed spectrum includes signaling an indication of different uplink access constraints so the UE connects to the base station when the UE and/or the uplink direction between the UE and the base station meet the uplink access constraints. The indication may be broadcast in a reference or synchronization signal, e.g., by utilizing unused or undesignated bits. Uplink access constraints may include a threshold distance of UEs from the base station, interference in the uplink direction (which may differ from interference in the downlink direction), etc. Based on the indicated constraints, the UE may determine whether or not to consider the base station as a candidate serving cell for wireless network access. The UE may be an in-flight aircraft and the base station may be a logical cell of a network that provides in-flight connectivity services.
