Abstract: Methods, systems, and devices for wireless communication are described. Data for a broadcast or multicast service may be sent over a control channel. A network device may broadcast a message to indicate a plurality of enhanced multimedia broadcast multicast service (eMBMS) services offered by the network. The mobile device may transmit an indication to the network device identifying an eMBMS service of interest. The network device may transmit a configuration message before broadcasting or multicasting data of the eMBMS service of interest. The configuration message may notify the mobile device of a control channel on which to receive the data related to the eMBMS service. The network device may then broadcast or multicast the eMBMS service data on the control channel. The data may be segmented at a particular protocol layer and mapped to several transmission time intervals within each repetition of the control channel.

Abstract: A multi-subscriber identification module (MSIM) wireless communication device may have at least a first SIM and a second SIM associated with a shared radio frequency (RF) resource. The wireless communication device may detect that the first SIM is set as a designated data subscription (DDS), such that a modem stack associated with the first SIM receives information broadcast by a first network. The wireless communication device may perform a network attach procedure with a second network on a modem stack associated with the second SIM, such that a default packet data network (PDN) connection is established with the second network. The wireless communication device may set the default PDN connection as a persistent PDN connection, with the modem stack associated with the second SIM maintaining at least one persistent PDN connection.

A method includes selecting one or more traffic management parameters associated with the WLAN based at least in part on one or more quality of service (QoS) parameters associated with the service of the wireless carrier network being accessed. The method further includes transmitting packets over the WLAN using the selected one or more traffic management parameters associated with the WLAN when a user equipment accesses the service of the wireless carrier network through the WLAN. The user equipment enforces the selected one or more traffic management parameters for communications to the wireless carrier network. An access point enforces the selected one or more traffic management parameters for communications to the user equipment.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives information from a network for discarding a data packet, identifies a data packet to be transmitted, determines whether the identified data packet is associated with at least one packet filter of a traffic flow template (TFT), and discards the identified data packet based on whether the identified data packet is associated with the at least one packet filter of the TFT. In an aspect, the apparatus identifies a data packet to be transmitted, determines whether the data packet is associated with at least one packet filter of the TFT, deactivates a link flow associated with the data packet based on whether the data packet is associated with the at least one packet filter of the TFT, and provides information to a device to discard the data packet associated with the deactivated link flow.

Abstract: Various aspects include methods for supporting handover of a Voice over Internet Protocol (IP) (VoIP) call, such as a Voice over Wi-Fi (VoWi-Fi) call, with a user equipment (UE). Various aspects may enable VoWi-Fi call handover from support via an evolved Packet Data Gateway (ePDG) to support via Long Term Evolution (LTE) when Voice over New Radio (NR) (VoNR) is not supported by a User Equipment (UE) computing device and/or a fifth generation (5G) standalone (SA) (5G SA) network in which the UE is located.

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: In a wireless network, a user equipment (UE) may support reflective quality of service (QoS), where QoS applied to uplink packets is implicitly derived from downlink packets. For example, when the UE receives a downlink packet that includes a reflective QoS (RQoS) indicator and a QoS flow identifier (QFI), the UE may apply the same QoS associated with the downlink packet to an uplink packet with one or more attributes that match the downlink packet. However, for a received downlink encapsulating security payload (ESP) packet that includes an RQoS indicator and a QFI, a modem cannot determine an uplink security parameters index (SPI) and downlink SPI pairing needed to enable RQoS because the uplink/downlink SPI pairing is known only by the upper layer. Accordingly, some aspects described herein enable the modem to learn uplink/downlink SPI pairings for ESP packets and thereby enable RQoS for ESP packets.

Abstract: Systems, methods, and devices for wireless communication that support mechanisms for identifying hyper frame number (HFN) desynchronization conditions and/or for triggering HFN resynchronization in a wireless communication system. In aspects, an HFN desynchronization condition is identified based on Ethernet frame validation. For example, aspects of the present disclosure provide mechanisms for validating and Ethernet frame. An HFN desynchronization condition is identified or detected when an Ethernet frame is determined to be corrupt based on the Ethernet frame validation in accordance with aspects herein. In some aspects, such as in Ethernet header compression (EHC) protocol implementations, an HFN desynchronization condition may be identified based on a determination that a deciphered context identification (CID) is not a valid CID (e.g., is not a CID in a set of valid CIDs).
