Abstract: This disclosure relates to techniques for a wireless device to detect and operate in an elevator or elevator-like conditions. The wireless device may establish a cellular link with a cellular base station. One or more conditions associated with being in an elevator may be detected. The wireless device may determine to operate in an elevator mode based at least in part on detecting the one or more conditions associated with being in an elevator. The wireless device may operate in the elevator mode. One or more conditions associated with exiting an elevator may be detected. The wireless device may determine to operate in a normal mode based at least in part on detecting the one or more conditions associated with exiting an elevator. The wireless device may operate in the normal mode.

Abstract: Transitioning a UE from a first RAT to a third RAT in an area having a first RAT, a second RAT, and a third RAT. The first RAT may be a second generation RAT, the second RAT may be a third generation RAT, and the third RAT may be a fourth generation RAT. The network of the first RAT may not provide information (e.g., a neighbor list) for the third RAT. The UE may use information to perform measurement of one or more base stations of the third RAT without attaching to the second RAT. For example, the UE may use pre-stored information to perform measurement of the third RAT. Alternatively, or additionally, the UE may receive the information (e.g., from a system information block) from the second RAT without attaching to the second RAT. The UE may then transition to from the first RAT to the third RAT.

Abstract translation: 在具有第一RAT，第二RAT和第三RAT的区域中将UE从第一RAT切换到第三RAT。 第一RAT可以是第二代RAT，第二RAT可以是第三代RAT，并且第三RAT可以是第四代RAT。 第一RAT的网络可能不提供第三RAT的信息（例如，邻居列表）。 UE可以使用信息来执行第三RAT的一个或多个基站的测量，而不附加到第二RAT。 例如，UE可以使用预先存储的信息来执行第三RAT的测量。 或者或另外，UE可以从第二RAT接收信息（例如，来自系统信息块），而不附加到第二RAT。 然后，UE可以从第一RAT转换到第三RAT。
