Abstract: Certain aspects of the present disclosure provide techniques for communicating, by a user equipment (UE), over multiple slices. A method that may be performed by the UE includes transmitting, from an operating system (OS) to a modem, an indication of a start network request originating from an application, the transmitting of the indication based on a determination that a traffic descriptor associated with the application is a non-default descriptor. The method may also include determining one or more parameters for establishing a new network connection for the application, the one or more parameters determined based on a routing policy that provides mapping between the traffic descriptor and the one or more parameters.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a user equipment (UE). The UE may be configured to transmit a message indicating an identifier (ID) associated with an application to a first edge computing system; receive first information associated with the application in response to transmitting the message, the first information indicating whether at least one second edge computing system configured to provide the application is accessible through at least one cell; and determine a set of cells through which the at least one second edge computing system is accessible based on the first information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a broadcast multicast service center (BMSC) device may receive, from a user equipment (UE) and via a first base station associated with a first radio access technology (RAT), a request for evolved multicast broadcast multimedia service (eMBMS) content. The BMSC device may transmit, to an access and mobility management function (AMF) device, a redirection request or a handover request, associated with the UE, from the first base station to a second base station associated with a second RAT. The BMSC device may transmit, to the UE and based at least in part on the UE being redirected or handed over to the second base station, the eMBMS content via the second base station. Numerous other aspects are provided.

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: Aspects directed towards Quality of Service (QoS) flow remapping are disclosed. In an example, upon detecting a mapping reconfiguration of a first QoS flow from a first data radio bearer (DRB) to another DRB, a Service Data Adaptation Protocol (SDAP) control protocol data unit (PDU) is generated indicating that a final SDAP data PDU associated with the first QoS flow has been transmitted on the first DRB. The SDAP control PDU is then transmitted via the first DRB. In another example, upon detecting a mapping reconfiguration of a first QoS flow from a first DRB to another DRB, an end marker parameter is set in an SDAP header of a first SDAP data PDU received from an upper layer after the mapping reconfiguration indicating that the first SDAP data PDU is a final SDAP data PDU associated with the first QoS flow transmitted on the first DRB.

Abstract: A user equipment (UE) enhances battery power during a connected discontinuous reception (C-DRX) off period. In one instance, the UE determines whether data arrives in a buffer of the UE and when a scheduling request occasion falls into a C-DRX off period (connected discontinuous reception off period). The UE also delays sending a scheduling request when uplink pre-scheduling is supported by a serving base station based on the determining and based on a periodicity of uplink (UL) prescheduling for periodic uplink prescheduling and/or a length of an uplink pre-scheduled grant for non-periodic uplink prescheduling.

Abstract: A user equipment (UE) reduces call drops caused by a delayed transmission of a measurement report. In one instance, the UE enters a sleep duration in a current C-DRX cycle (connected discontinuous reception cycle) while in connected mode on a serving cell of a first RAT (radio access technology). The UE then evaluates one or more neighbor cells of a second RAT, for potential handover, during the sleep duration by performing inter radio access technology (IRAT) measurement. The UE also determines whether to wake up prior to a scheduled end of the sleep duration and send a scheduling request before the scheduled end when inter radio access technology (IRAT) measurement is completed. The determination can be based on a signal quality of the serving cell, a signal quality of the at least one neighbor cell, and a remaining time of the sleep duration in the current C-DRX cycle.

Abstract: A user equipment (UE) performs combined gap and gap-less measurement procedures. In one instance, the UE performs inter-radio access technology (IRAT) measurement of a neighbor frequency of a second radio access technology (RAT) during a measurement gap allocated by a base station of a first RAT in response to a trigger for inter-RAT handover from the first RAT to the second RAT. The UE also performs downlink timing detection of the neighbor frequency of the second RAT with a second receive chain based on the IRAT measurement.

Abstract: Decoding failure and throughput loss are reduced when a user equipment (UE) tunes away from a first radio access technology (RAT) to a second radio access technology. In one instance, the UE determines when one or more receive chains will tune away from a first subscriber identity module (SIM) to another SIM. The UE reports a channel state based on measurements obtained without the one or more receive chains during the determined tune away and/or during a predetermined time period before the determined tune away. The UE also reports the channel state based on measurements obtained with the one or more receive chains after the one or more receive chains return from the determined tune away.

Abstract: A user equipment (UE) adjusts a system information block (SIB) read abort timer to reduce mobile terminated circuit-switched fallback (CSFB) failure. In one instance, the UE receives a redirection list including frequencies to search for redirection and searches each frequency in the list to determine a strongest frequency. The UE then decodes short period system information blocks (SIBs) for a variable number of non-strongest frequencies until a strongest short period SIB is received. The UE adjusts a SIB read abort timer based on a signal quality of the strongest frequency and the variable number.
