Abstract: Aspects are provided which allow a UE to disable measurements of reference signals from 5G base stations which are inapplicable to EN-DC. The UE may receive a reference signal from a base station. The UE may identify a frequency range. The UE may determine whether to measure the reference signal based on whether the reference signal is within the identified frequency range. The UE may refrain from measuring the reference signal in response to the determination. The UE may also refrain from measuring the reference signal in response to a SIB received at the UE not including a ULI, or in response to a frequency associated with the reference signal not being in a list of supported bands for EN-DC. As a result, inter-RAT handovers from LTE base stations to 5G base stations are prevented, UE power consumption is thereby saved, and support for EN-DC is maintained.

Abstract: Aspects are directed towards activating out-of-order delivery (OOOD) on a user equipment (UE). An application programming interface (API) on the UE may set one or more configuration parameters for IP flows from the wireless network. The UE may then measure the IP flows from the wireless network, traffic flow templates (TFTs), and/or quality-of service flows (QFI) to identify measured IP flows from the wireless network meet the one or more configuration parameters. The UE may then activate OOOD for the IP flows from the wireless network that meet the one or more configuration parameters.

Abstract: This disclosure provides systems, methods, apparatuses and computer-readable medium for wireless communication. In some aspects, a user equipment (UE) may receive, from a first base station (BS) associated with a fifth generation New Radio (5G NR) radio access technology (RAT), a command of mobility from the 5G NR RAT to a second RAT. The UE may determine that the command of mobility is for voice fallback. The UE may transmit, to a second BS associated with the second RAT and based at least in part on determining that the command of mobility is for voice fallback, a radio resource control (RRC) connection request communication for attempting to communicatively connect with the second BS for voice fallback.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus, e.g., a base station, maybe configured to obtain UE information of a UE. The apparatus may configure one or more parameters of one or more measurement gaps based on the UE information, and transmit, to the UE, measurement gap information on the one or more measurement gaps. The measurement gap information may include the one or more configured parameters. In another aspect of the disclosure, a UE maybe configured to transmit, to a base station, UE information of the UE. The UE may receive a measurement request from the base station in response to the UE information, where the measurement request includes configuration information for one or more measurement gaps based on the transmitted UE information. The UE may measure one or more reference signals during at least one measurement gap.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for improving inter-Radio Access Technology (RAT) measurements. A user equipment (UE) determines, while in a connected state Discontinuous Reception (CDRX) mode in a first cell of a first Radio Access Technology Network (RAT), that a second cell of a second RAT is to be measured. The UE schedules at least two operational periods related to transitioning between ON and OFF states of the CDRX mode to overlap, to increase a period available for measuring signals in the second cell.

Abstract: In an embodiment, a server determines a first support state for the group communication session that defines a first set of sectors belonging to a multicast/broadcast single frequency network (MBSFN) area for transmission of the session media for the group communication session via Internet Protocol (IP) multicast. The server then transitions the group communication session from the first support state to a second support state that defines a second set of sectors belonging to the MBSFN area for transmission of the session media for the group communication session via IP multicast. Before the transition, the server delivers the session media to the first set of sectors via IP multicast in accordance with the first support state. After the transition, the server delivers the session media to the second set of sectors via IP multicast in accordance with the second support state.

Abstract: Certain aspects of the present disclosure provide techniques for selecting a public land mobile network (PLMN) based on route information. A method that may be performed by a wireless node includes camping on a first cellular network on a first frequency band of one or more first frequency bands associated with a first mobile country code (MCC) of a planned route of the wireless node; detecting a condition with the first cellular network after the camping on the first cellular network; and searching, after detecting the condition, for service on the one or more first frequency bands and one or more second frequency bands associated with a second MCC, wherein the one or more second frequency bands are selected based on the first MCC and the planned route.

Abstract: The UE may store target cell information to a database based on performing a handover to the target cell and detecting the ping-pong handover based on a number of handover instances in the database of the target cell to which the UE has performed the handover being greater than or equal to a threshold number of the handover instances within a period of time. The UE may receive, from a base station a list of ping-pong cell candidates and configure the number of handover instances of the target cell and/or the period of time based on the list of ping-pong cell candidates. The UE may avoid or reduce the handover to the identified ping-pong cell based on the detected ping-pong handover by applying an offset to the measurement of the target cell.

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.
