Abstract: 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.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications. In some aspects, a wireless communication device may determine, based on a tracking area update (TAU) accept message that a tracking area is out of synchronization. In some aspects, the wireless communication device may trigger, after expiration of a timer, a TAU procedure based on determining that the tracking area is out of synchronization. Numerous other aspects are provided.

Abstract: Disclosed are methods and apparatus optimizing the performance of a radio access technology, such as LTE, in a single radio wireless communication system supporting multiple radio access technologies, such as both LTE and 1x CDMA. The methods and apparatus effectuate this optimization in a single radio LTE (SRLTE) device, for example, through increasing system parameters, such as Slot Cycle Index (SCI) related to a maximum allowed periodicity of when a wireless device tune away from a LTE data call to monitor paging from 1x CDMA. Increasing the SCI value in the wireless device reduces the periodicity of 1x CDMA paging tune away from an LTE data call, thereby optimizing the LTE performance.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus may be a first device. The first device operates a ROHC compressor in a first state at a ROHC sublayer to compress a first packet to be transmitted to a second device. The first packet includes information for a ROHC decompressor to establish a ROHC context. The information enables the ROHC decompressor to decompress a second packet compressed by the ROHC compressor when operating in a second state. The first device determines, at a sublayer or a layer lower than the ROHC sublayer, whether the first packet has been successfully received at the second device. The first device continues operating the ROHC compressor in the first state in response to a determination that the first packet has not been successfully received at the second device.

The method includes communicating with a device over a first network. The method further includes monitoring for a second network during the communication with the device, the second network having a higher throughput than the first network. The method further includes determining an application usage history of the device. The method further includes selectively transitioning the communication from the first network to the second network based on a parameter of the first network, a parameter of the second network, and an application usage history of the device.

Abstract: Disclosed are methods and apparatus for reducing a call setup time in wireless communication systems, particularly for systems employing SVLTE where an LTE network is used for data and a 1×CDMA network for voice. The methods and apparatus feature the capability during mobile terminated (MT) calls to modify a normal mode of operation of a predefined operation in a mobile terminal (e.g., call switched fallback (CSFB)), wherein processes normally performed for between a first network (e.g., LTE) are not performed in the mobile terminal, allowing a page response message to be sent directly, and thus sooner, to the other network (e.g., 1×CDMA) in response to an MT call page. This hybrid operation allowing the skipping of normal processes reduces the time for call set up.
