Abstract: Certain aspects of the present disclosure provide techniques for protecting shared low noise amplifiers by limiting transmission power. A method that may be performed by a user equipment (UE) includes determining that a transmission by the UE on a frequency band via a first radio access technology (RAT) overlaps in time with a period that the UE is configured to receive on the frequency band via a second RAT; and limiting transmission power on the first RAT during the period.

Abstract: Methods, systems, and devices for wireless communication are described. A multi-antenna user equipment (UE) may communicate with a base station using a first antenna, determine to switch from the first antenna to a second antenna for communicating with the base station, determine a silence window in which communication with the base station is suspended, schedule the switch from the first antenna to the second antenna to occur during the silence window, and switch from the first antenna to the second antenna during the silence window.

Abstract: A method of wireless communication at a user equipment (UE) is presented. The UE may include one or more antennas which are shared between a first network connection and a second network connection in a dual connectivity mode. The method includes reporting a first sounding reference signal (SRS) antenna-switching capability to a base station. The method also includes transmitting an SRS to the base station via a second SRS antenna-switching capability when the first network connection has priority over the second network connection, where the second SRS antenna-switching capability is reduced with respect to the first SRS antenna-switching capability.

Abstract: Systems, apparatuses, and methods for gap-based antenna measurement for antenna switch diversity, where there are fewer number of receivers or transmitters than the number of available antennas. The receivers may switch to additional antennas during a gap and switch back to the previous antennas. A device may select which antennas to use for communications based at least on measurements of additional antennas, thus supporting antenna switch diversity despite having fewer number of receiver chains.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may detect a collision of paging messages for a first subscription and a second subscription of the wireless device during a paging processing duration, the first receive chain including at least one antenna path. The wireless device may determine that, in a connected mode, it is configured to operate a second receive chain with one or more additional antenna paths, and may allocate, for a subsequent instance of the paging processing duration, the first subscription to one of the first receive chain or the second receive chain, and the second subscription to the other of the first receive chain or the second receive chain. The wireless device may monitor, during the subsequent instance of the paging processing duration, for a first paging message and a second paging message using the first and second receive chains.

Abstract: The present disclosure provides a method, apparatus, and computer-readable medium that is able to avoid ping pong mobility when a redirection procedure fails. The apparatus may attempt to perform a redirection procedure from a first RAT to a target frequency of a second RAT. The apparatus may receive a redirection failure notification indicating that the target frequency of the second RAT is unavailable. The apparatus may refrain from initiating a reselection procedure to the target frequency of the second RAT for a predetermined time period. The apparatus may deprioritize the target frequency of the second RAT for the predetermined time period when the target frequency of the second RAT is unavailable and is present in an SIB received from the neighbor cell. The apparatus may generate a list of banned frequencies that includes the target frequency of the second RAT when the target frequency of the second RAT is unavailable.

Abstract: The present disclosure presents a method and an apparatus for inter radio access technology (IRAT) cell reselection. For example, the method may include identifying that a user equipment (UE) in an idle or a discontinuous reception (DRX) mode is camped on a cell of a first RAT, determining that the cell the UE is camped on is not broadcasting any neighbor cell of a second RAT, scanning for one or more frequencies of the second RAT based on the determination, and triggering a cell reselection to a cell of the second RAT, wherein the cell of the second RAT is associated with a frequency identified during the scanning. As such, an autonomous IRAT cell reselection may be achieved.

Abstract: A user equipment (UE) prioritizes searches and/or measurements of neighbor cells/frequencies based on a level of mobility of a UE. In one instance, the UE identifies a priority of a layer of a radio access technology (RAT) to be measured or searched and identifies a level of mobility of the UE. A sensor module of the UE may determine the level of mobility of the UE and generate an indication corresponding to the level of mobility of the UE. The UE prioritizes a periodicity of interlayer search and/or measurement based on the priority of the layer to be measured and the level of the mobility of the UE.
