Abstract: This disclosure relates to techniques for multi-RAT and DSDA capable wireless devices to handle frame blanking in a wireless communication system. A wireless device may establish wireless links according to a first radio access technology and a second radio access technology. The wireless device may determine to perform transmit and receive blanking for one or more antennas of the wireless device for the first radio access technology to perform sounding reference signal transmissions for the second radio access technology based at least in part on a band combination for the wireless links. The wireless device may determine a modification to channel state feedback reporting for the first radio access technology based at least in part on the transmit and receive blanking. The wireless device may perform channel state feedback reporting using the determined modification.

Abstract: A mobile device collects received information and processes it. In some instances, the mobile device detects, based on the collected information, that a base station is likely not legitimate, i.e., it is likely a fake base station, and the mobile device bars communication with the base station for a time. In some embodiments, the mobile device determines, based on the received information, that the base station is a genuine base station. When the mobile device determines that the base station is a genuine base station or the mobile device does not determine that it is likely the base station is a fake base station, the mobile device allows or continues communication with the base station.

Abstract: This disclosure relates to techniques for performing radio link monitoring and cell searching when moving at high speeds. A movement speed of a wireless device may be determined. When performing a cell search, the manner of the cell search may depend on the movement speed of the wireless device, potentially including cells that are associated with high movement speed being more highly prioritized when the wireless device is determined to be at a higher movement speed than when the wireless device is determined to be at a lower movement speed.

Abstract: Apparatus and methods to manage data connections to multiple wireless networks in a wireless communication device supporting multiple subscriber identities via multiple subscriber identity modules (SIMs) are disclosed. A representative method includes detecting an application request to establish a data connection; obtaining a preference for prioritization of data connections for the multiple SIMs; and based on the preference, establishing the data connection with a wireless network associated with one of the multiple SIMs. In representative embodiments, the preference is based on a user specified or default prioritization of the multiple SIMs, an order of radio access technologies (RATs), one or more quality metrics, data rates supported, and/or availability of wireless local area networks for the data connections.

Abstract: A method, system, and apparatus are described for managing a device in a mixed wireless communication system. A device may decide to scan or not scan for a cell based on (or at least on) updating information. The updating information may be used together or individually. The updating information may be maintaining a time window in conjunction with a device's motion status, maintaining a list that tracks cell identity in areas of non-service, or utilizing network deployment information.
Abstract translation: 描述了用于管理混合无线通信系统中的设备的方法，系统和装置。 基于（或至少）更新信息，设备可以决定扫描或不扫描小区。 更新信息可以一起使用或单独使用。 更新信息可以与设备的运动状态一起保持时间窗口，维护在非服务区域中跟踪小区标识的列表，或者利用网络部署信息。

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.
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。
