Abstract: Disclosed are techniques for wireless communication. In an aspect, information associated with a Positioning System Information Block (PosSIB) is updated based on a UE-determined PosSIB-update periodicity, a UE-determined post-PosSIB decoding time offset, a PosSIB update schedule for a PosSIB group to which the PosSIB of the first type belongs, or any combination thereof. In another aspect, a system information block 1 (SIB1) for each PosSIB in a set of PosSIBs is received by UE. Each PosSIB in the set of PosSIBs is associated with a different PosSIB type, and each SIB1 comprises a value tag and an expiration timer for a respective PosSIB in the set of PosSIBs. Each PosSIB in the set of PosSIBs in accordance with the value tag and the expiration timer of the respective SIB1.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from an application processor associated with the UE, an indication of a traffic service type and whether an uplink data stall has occurred. The UE may detect that one or more threshold criteria are satisfied for a serving cell, wherein a threshold value associated with at least one of the one or more threshold criteria is based at least in part on the traffic service type. The UE may transmit information associated with one or more adjusted measurement values of the serving cell based at least in part on detecting that the one or more threshold criteria are satisfied. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish, by a first subscription of the UE, a connection to a first network entity using two transmit (Tx) chains of the UE. The UE may receive, by a second subscription of the UE, a paging message from a second network entity. The UE may receive, by the first subscription from the second subscription, a request for the first subscription to enter a mode that supports one Tx chain. The UE, by the first subscription, may reduce the two Tx chains to the one Tx chain for the first subscription. The UE may perform, by the second subscription to the second network entity, the connection setup based at least in part on the first subscription reducing the two Tx chains to the one Tx chain. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods and apparatuses for measurement of cells and determination of a non-standalone (NSA) coverage status using an NSA coverage database. The NSA coverage database may indicate candidate frequencies of New Radio (NR) cells that provide NSA coverage corresponding to a given Long Term Evolution (LTE) serving cell. The NSA coverage database may also indicate whether a system information block 1 (SIB1) has been previously received on a candidate frequency. The user equipment (UE) may perform measurement of candidate frequencies using the NSA coverage database, and may identify cases where a cell not providing NSA coverage has a same candidate frequency as a cell providing NSA coverage using the indication of whether SIB1 has been previously received on a candidate frequency.

Abstract: A method of wireless communication, by a user equipment (UE), includes setting up a secondary cell group (SCG) with a second radio access technology (RAT) that differs from a first RAT associated with a master cell group (MCG). The method also includes communicating wirelessly via the secondary cell group and the master cell group. The method further includes predicting a radio link failure (RLF) for the secondary cell group based on multiple inputs to a machine learning model. The method still further includes routing data transmission from the secondary cell group to the master cell group, after predicting the SCG RLF.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish a first call associated with a first subscriber of the UE. The UE may establish a second call associated with a second subscriber of the UE, wherein the first subscriber and the second subscriber are active contemporaneously, and wherein the first call and the second call are associated with a first radio access technology (RAT). The UE may identify a mobility event that associated with an interruption to at least one of the first call and the second call, the mobility event involving switching the first subscriber to a second RAT. The UE may perform a mitigation action. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish, in a communication mode, a communication connection with a first radio access technology (RAT) or a second RAT. The UE may receive or identify an indication to deprioritize the first RAT. The UE may perform, based at least in part on the indication to deprioritize the first RAT, an action to deprioritize the first RAT, where the action is based at least in part in the communication mode. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for packet buffering. A method that may be performed by a receiving node includes dynamically determining one or more time durations to buffer packets. The one or more time durations can be different than a time duration of a configured timer for buffering the packets. The receiving node may input one or more parameters to a machine learning algorithm and obtain, as output of the machine learning algorithm based on the input one or more parameters, one or more time durations to buffer packets. The receiving node buffers packets for the determined one or more time durations. The receiving node may use machine learning to dynamically determine the one or more time durations to buffer packet. The buffering may be at a radio link control (RLC) reassembling buffer and/or a packet data convergence protocol (PDCP) buffer.

Abstract: Methods, systems, and devices are described for concurrently performing handoff-related measurements for neighbor cells using multiple input multiple output (MIMO) antenna resources. In one example, a mobile device is in communication with a serving cell. Handoff-related measurements of first wireless signals from a first neighbor cell are performed. The first wireless signals are received at first MIMO antenna resources of a device. Handoff-related measurements of second wireless signals from a second neighbor cell are performed, as well. The second wireless signals are received at second MIMO antenna resources concurrently with the first wireless signals received at the first MIMO antenna resources. The first handoff-related measurements and the second handoff-related measurements may be performed during a scan interval. A type of handoff-related measurement to perform may be determined based on a determined length of the scan interval.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a network configuration procedure has failed a threshold number of times for a first radio access technology (RAT). The UE may perform a first action to prevent execution of the network configuration procedure until a timer has elapsed based at least in part on determining that the network configuration procedure has failed the threshold number of times. The first action may include transmitting a message that indicates that the UE does not have a capability to communicate using the first RAT, barring a cell or a tracking area of the first RAT or a second RAT that assists with establishing a radio access network connection for the first RAT, and/or refraining from reporting measurement results for the first RAT. Numerous other aspects are provided.
