Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a modem may receive, from an applications processor of a user equipment (UE), a registration message associated with keep alive offloading. Accordingly, the modem may filter incoming transmission control protocol (TCP) packets to determine a current sequence number and a current acknowledgement number. The modem may further receive, from the applications processor, an indication to perform a keep alive procedure. Accordingly, the modem may transmit, periodically, TCP keep alive packets based on the current sequence number and the current acknowledgement number. Numerous other aspects are described.
Abstract:
An apparatus for wireless communication includes a memory and a processor coupled to the memory. The processor is configured to send a data session establishment request to establish a data session with a network device using a wireless communication network. The data session establishment request has a first field to indicate a requested network slice for the data session. The processor is further to receive an indication of a granted network slice for the data session and to receive an indication of a back-off timer value from the network device. The processor is further configured, after expiration of a back-off timer based on the back-off timer value, to send a first message associated with the granted network slice and to send a second message having a second field corresponding to the first field of the data session establishment request.
Abstract:
Aspects of the present disclosure generally relate to wireless communications. In some aspects, a device may determine, during a first time period when a power saving feature is disabled, a first performance parameter associated with an application executing on a user equipment (UE). The device may determine, during a second time period when the power saving feature is enabled, a second performance parameter associated with the application executing on the UE. The device may determine whether to enable or disable the power saving feature for the application based at least in part on the first performance parameter and the second performance parameter.
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:
The present disclosure provides user equipment power consumption and secondary cell (SCell) activation latency reductions in wireless communication systems. For example, a UE may determine that a secondary cell activation condition has been satisfied. The UE may further transition to a secondary cell activated state based on determining that the secondary cell activation condition has been satisfied, the secondary cell activate state corresponding to a dormant SCell state. The UE may operate at least in the dormant SCell state.
Abstract:
Methods, systems, and devices are described for passively and dynamically determining network timeout (NTO) values. The method may include adjusting an amount of delay applied to transmissions on an existing connection to a device in a network and determining how long the existing connection is allowed to remain idle before the existing connection expires based on the adjusting of the amount of delay applied to the transmissions on the existing connection.
Abstract:
Methods, systems, and devices are described for determining a quality estimation of a wireless network that may be used to determine whether a particular wireless network meets one or more criteria for association with a station. The quality estimation may be based on a load quality of a basic service set (BSS) of an available wireless network and/or one or more wide area network (WAN) metrics associated with the wireless network. A station may evaluate such load quality and WAN metrics prior to association, and/or after association with a wireless network.
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:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may configure a first channel associated with a first subscriber identity module (SIM), the first SIM associated with data traffic. The UE may configure a second channel associated with a second SIM in a dual SIM dual active (DSDA) mode. The UE may detect, on the second channel, a subscription related data stream that includes voice call traffic. The UE may determine, based on detecting the subscription related data stream, to switch the data traffic from the first SIM to the second SIM based at least in part on a UE operation mode. The UE may switch the data traffic from the first SIM to the second SIM based at least in part on the determination to switch the data traffic. Numerous other aspects are described.
Abstract:
Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for updating QoS configurations at a user equipment (UE). An example method generally includes receiving, from a network entity, quality of service (QoS) information, a QoS identifier associated with the QoS information, and a bearer context associated with the QoS information in one of a modify bearer context request message, an activate default bearer context request message, or an activate dedicated bearer context request message; and updating a QoS configuration using the QoS information based on whether the UE is already configured with QoS information associated with the QoS identifier for a bearer context different from the bearer context associated with the QoS information received in the modify bearer context request message, activate default bearer context request message, or activate dedicated bearer context request message.
