Abstract: Aspects of the present disclosure provide apparatus and techniques for determining one or more operating conditions related to a UE and transmitting a power preference indication (PPI) to an eNB based, at least in part, on the determination. The one or more operating conditions may be related to at least one of a throughput, battery configuration, application data history, or temperature of the UE. In response to the determination, the UE may transmit one of a PPI that is set to or indicates normal power mode or a PPI that is set to low power mode, for example. Additionally, the UE may decide whether or not to delay sending a scheduling request (SR) to the eNB based, at least in part, on the determination.

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: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a resource grant for an uplink transmission of uplink information on a logical channel. The uplink information may be stored in an uplink buffer. The UE may initiate a buffer status report retransmission timer in response to receiving the resource grant. The UE may determine that the resource grant allocates resources that are sufficient to transmit a portion of the uplink information that satisfies a threshold. The UE may stop the buffer status report retransmission timer in response to the determining.

Abstract: Methods, systems, and devices for wireless communication are described for wireless communication related to Multimedia Broadcast Multicast Service (MBMS) signaling. A user equipment (UE) may receive multiple messages on multiple cells requesting an indication of MBMS services that the UE is interested in receiving. The UE may receive a first message on a primary cell (PCell) and a second message on a secondary cell (SCell) or a configurable SCell (C-SCell) at approximately the same time. In some cases, these messages may include a list of services offered by a network to the UE. The UE may then configure a response message to include information that may be used by the network to determine which cell and to which request message the response message is responsive. In some cases, the response message may include a cell identification, frequency identification, or an area identification associated with the corresponding request message.

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: Aspects of the present disclosure provide example apparatus, methods, processing systems, and computer readable mediums implementing techniques for modifying a configuration of a radio bearer based on a request for quality of service (QoS) for a communication flow. In aspects, a user equipment (UE) receives a request for a QoS for a communication flow and maps the communication flow to a radio bearer based on a downlink map. The UE is configured to communicate over a number of radio bearers. The downlink map associates one or more communication flows to one or more of the number of radio bearers. The UE then modifies a configuration of the radio bearer based on the request for the QoS. During operation, the UE receives one or more downlink packets on the radio bearer and processes the one or more downlink packets according to the QoS.

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.

Abstract: Wireless communication methods, devices, and systems to reduce latency when network access (e.g., cellular network access) is barred are described. A method includes receiving, by a user equipment (UE) from an application, a request for at least one of establishment of a packet data unit (PDU) session or uplink (UL) data transfer via a previously established PDU session. The method additionally includes evaluating that access to a first network (e.g., a 3rd Generation Partnership Project (3GPP) network) is barred. The method also includes determining that the access barring time exceeds a threshold, and checking, in response to the determining, that configured policies permit the PDU session to be on a second network (e.g., a non-3GPP network). The method further includes transferring data of the PDU session in accordance with the configured policies. Other aspects and features are also claimed and described.

Abstract: Certain aspects of the present disclosure provide techniques for avoiding out of order uplink data reception upon data radio bearer (DRB) release or quality of service (QoS) flow addition. An exemplary method that may be performed by a user equipment (UE), includes obtaining an indication that a first data radio bearer (DRB) is released or handed over to a second DRB, wherein a first mapping maps a first quality of service (QoS) flow to the first DRB; obtaining a second mapping that maps the first QoS flow to a second DRB; editing service data adaptation protocol (SDAP) headers of uplink protocol data units (PDUs) in an uplink transmission buffer associated with the first DRB, based on a difference between a first configuration of the first DRB and a second configuration of the second DRB; and transmitting the uplink PDUs via the second DRB.
