摘要： Methods, systems, and devices are described for early radio link failure (RLF) declaration. A UE may identify a measurement report message (MRM) trigger and initiate an RLF procedure. In the RLF procedure the UE may determine whether a radio link condition indicative of an RLF has been satisfied before an expiration of a timer that is initiated by the MRM trigger. As an example, the UE may determine that a threshold number of uplink radio link signaling messages, such as MRMs, have been transmitted without a radio link control (RLC) acknowledgement (ACK). The UE may declare RLF based on the determination that the radio link condition has been satisfied. In some examples the UE may verify that channel conditions are better for a target cell than for the serving cell, and may declare RLF based further on the channel comparison.

摘要： Methods, systems, and devices are described for wireless communication at a UE. A user equipment (UE) may establish a connection to a serving cell and monitor channel conditions for the serving cell and neighboring cells. Based on the channel conditions, the UE may determine to read the system information of a non-serving neighbor. The UE may then read the system information of the non-serving neighbor cell while still connected to the serving cell. In some cases, the UE may store the system information in a database. When the time comes for the UE to access the neighbor cell (e.g., if the link to the serving cell fails) the UE may proceed with access procedures without delay using the stored system information.
摘要翻译：描述了用于UE处的无线通信的方法，系统和设备。用户设备（UE）可以建立到服务小区的连接并监视服务小区和相邻小区的信道状况。基于信道条件，UE可以确定读取非服务邻居的系统信息。然后，UE可以在仍然连接到服务小区的同时读取非服务相邻小区的系统信息。在一些情况下，UE可以将系统信息存储在数据库中。当UE到达相邻小区的时间（例如，如果到服务小区的链路发生故障），则UE可以使用所存储的系统信息不间断地进行访问过程。

摘要： Aspects of managing a connection in a wireless communication system are described. As an example, the aspects may include deleting, at a base station, context information associated with a radio connection of a user equipment (UE) with the base station when the base station stops serving the UE. Further, the aspects may include transmitting, by the base station, a context drop notification to one or more neighboring base stations, wherein the context drop notification indicates that the context information associated with the UE has been deleted at the base station. As such, based on associating the UE with the deleted context information, the base station or the one or more neighboring base stations may avoid attempting to fetch the context information of the UE from other neighboring base stations in response to receiving a connection re-establishment request from the UE.

摘要： Methods, systems, and devices are described for wireless communication, including for intelligent mode selection for circuit switched fall back devices. A user equipment (UE) attached to a wireless network may determine that circuit switched fall back (CSFB) service is not available. The UE may thus elect to operate in a packet switched (PS) operating mode until CSFB service again becomes available. For example, the UE may receive a system information block (SIB) indicating that the CSFB connection is not available, the UE may attempt to access a CSFB a predetermined number of times, or the UE may miss a number of voice calls. The UE may, based on this determination, select a packet switched (PS) operating mode. The UE may continue to exchange PS data with the serving cell based on the PS operating mode. The UE may then periodically evaluate the signal quality for a 1x cell.

摘要： Wireless communication techniques that include autonomous beam selection performed by a mobile device are discussed. A mobile device may receive a first SSB on a current-serving reception beam and receive other SSBs on different reception beams. The mobile device may autonomously switch beams during communication without instruction from another device. A UE can adjust from one beam to another while performing wireless communication using a current-serving reception beam to performing wireless communication using a second reception beam. A switch can occur upon determining that the quality of wireless communication performed using the second reception beam on which a second SSB was received is higher than the quality of wireless communication performed using the current-serving reception beam on which the first SSB was received. Other features are also described.

摘要： Certain aspects of the present disclosure relate to techniques and apparatus for optimizing long term evolution (LTE) connected discontinuous reception (CDRX) for single radio hybrid tune away devices. Certain aspects provide a method for wireless communications by a user equipment (UE). The method generally includes entering a DRX mode wherein the UE alternates between an activity period and an inactivity period while connected to a first radio access technology (RAT) network, tuning away from the first RAT network for a tune away period to monitor signals in a second RAT network, determining when an inactivity timer for the DRX mode expires or will expire, and adjusting a value of the inactivity timer based, at least in part, on the determination.
