A UE may include one or more application processors and a modem processor. The modem processor may include flow priority engine configured to receive, from the one or more application processors, requests for determining priority treatment of one or more packet filters of one or more uplink transmissions and transmit the one or more uplink transmissions to a base station based on priorities of the one or more uplink transmissions. The priorities of the uplink transmissions may be determined based on at least one of the requests for priority treatment received from the one or more application processors, mapping of uplink transmissions to radio bearers, the priorities of the radio bearers, or one or more configuration rules.

Method and apparatus for prioritizing uplink or downlink flows in multi-processor device

This disclosure provides a method, apparatus, and computer-readable medium for wireless communication at a modem, comprising receiving, via an interface with a host, an internet protocol (IP) packet including a first transport protocol header and a first IP header. The IP packet has a size greater than a maximum transport unit (MTU) size allowable for each packet transmitted over a communication link. The modem segments the IP packet into a plurality of segments based on a segment size indicated by a segmentation policy. Each segment includes a respective derived segment transport protocol header and a respective derived segment IP header derived from the IP packet. Each of these derived headers includes at least one field based on the segmentation policy, and each of the segment transport protocol headers includes a checksum for the respective segment. Additionally, the modem transmits the plurality of segments over the communication link.

Uplink segmentation offload to modem

Aspects disclosed in the detailed description include power saving techniques in computing devices. In particular, as data is received by a modem processor in a computing device, the data is held until the expiration of a modem timer. The data is then passed to an application processor in the computing device over a peripheral component interconnect express (PCIe) interconnectivity bus. On receipt of the data from the modem processor, the application processor sends data held by the application processor to the modem processor over the PCIe interconnectivity bus. The application processor also has an uplink timer. If no data is received from the modem processor before expiration of the uplink timer, the application processor sends any collected data to the modem processor at expiration of the uplink timer. However, if data is received from the modem processor, the uplink timer is reset.

Power saving techniques in computing devices

Various aspects of the present disclosure generally relate to wired and/or wireless communication. In some aspects, a device may receive a plurality of data packets at a modem of the device. The device may group, at the modem of the device, payloads of a first subset of the plurality of data packets into a container. The device may transfer, to a processor of the device and using the modem, the container via a first interface channel. The device may transfer, to the processor and using the modem, a second subset of the plurality of data packets via a second interface channel. Numerous other aspects are provided.

Transmission control protocol (TCP) and/or user datagram protocol (UDP) receive offloading

A method for reordering data by an electronic device is described, including receiving a first set of data packets via a first radio access technology (RAT). The method also includes receiving a second set of data packets via a second RAT. The first and second sets of data packets are from a data stream. The method further includes providing at least a portion of the first set of data packets or of the second set of data packets to an application processor. The method additionally includes buffering, in application processor memory, the at least the portion of the first set of data packets or the at least the portion of the second set of data packets. The method also includes reordering the at least the portion of the first set of data packets or the at least the portion of the second set of data packets.

Systems and methods for reordering data received from a plurality of radio access technologies (RATs)

Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to methods and apparatus for utilizing a control protocol to establish multiple packet data network (PDN) connections through a trusted wide area network (TWAN). Techniques are provided for expanding mobile network capacity by offloading traffic from wireless wide area networks (WWAN) to other types of networks, including wireless local area networks (WLAN).

Transport of control protocol for trusted WLAN (TWAN) offload

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a network device. The apparatus receives an evolved multimedia broadcast multicast service (eMBMS) data from a base station via multicast transmission. The apparatus transmits the received eMBMS data to one or more end nodes via unicast transmission. In an aspect, the one or more end nodes are connected to the network device via a local area network (LAN).

EMBMS over home sharing environment

Aspects of the present disclosure provide methods and apparatus for offloading checksum processing in a user equipment (UE) (e.g., from an application processor to a modem processor). Such offloading may speed up packet processing, increase data rate, and/or free up resources of the application processor for other tasks.

Methods and apparatus for offloading checksum processing

A first method includes transmitting, to a network, an indication of a capability to operate in an uplink aggregation dual connectivity mode or in a fast switching dual connectivity mode; and receiving, from the network, a dual connectivity configuration for the UE based at least in part on the indication of the capability. A second method includes communicating with a first network access device; transmitting, to a second network access device, a request to perform fast switching from the first network access device to the second network access device; receiving, from the second network access device, a dual connectivity configuration for communicating with the second network access device; and communicating with the second network access device based at least in part on the dual connectivity configuration.

Techniques for managing dual connectivity in an uplink

Systems and methodologies are described herein that facilitate efficient transfer of quality of service (QoS) context during inter-radio access technology (RAT) handovers. In particular, techniques are described herein for establishing rules for whether a user equipment unit (UE) or an associated network should establish QoS for a mixed-mode application, identifying flow to bearer mappings when translating QoS across an inter-RAT handover, mapping QoS parameters of respective RATs, mitigating QoS depreciation upon multiple handovers, performing one or more actions if QoS is not acceptable in a new RAT, maintaining QoS during tunnel mode, and handling scenarios in which a UE moves between a RAT using network-initiated QoS and a RAT using UE-initiated QoS.

Method and apparatus for QoS context transfer during inter radio access technology handover in a wireless communication system

Systems and methods are disclosed for supporting, in a device, Wireless Local Area Network (WLAN)-Wireless Wide Area Network (WWAN) mobility, data offload, and simultaneous usage of different access networks on a per Access Point Name (APN) basis. The device determines an access network among WWAN and WLAN for a data stream having an APN. The device additionally hands off the data stream according to the determined access network, while maintaining Internet Protocol (IP) continuity. The device further routes packets of the data stream to at least one of a protocol stack or interface for the determined access network in accordance with an inter-system routing policy (ISRP).

Systems and methods supporting WLAN-WWAN mobility in devices

A method, an apparatus, and a computer program product for wireless communication are provided. A multi-radio device controls wireless communications by identifying one or more connection points between radio(s) of the multi-radio device and an operating system executing on a host device, analyzing a policy relating to the multi-radio device, and exposing, to the operating system, a subset of the connection points based on the policy. A modem manages a connection to an applications processor (AP) by virtualizing physical communication interfaces at the modem, providing a single Internet protocol (IP) interface representing the virtualized physical communication interfaces to a high level operating system (HLOS) at the AP, detecting a physical communication interface connected to the modem, and determining whether to expose the detected physical communication interface to the HLOS as a standalone virtualized physical communication interface, or hide the detected physical communication interface as part of an existing virtualized physical communication interface.

Configurable host interface using multi-radio device and architecture for WLAN offload

The embodiments simplify the development of applications for current and future wireless communication devices, resolving the deficiencies of current methods by providing a hierarchical routing layer which abstracts the actual proximity of the network connection. An application can request and receive a type of network connection without having to address details of the actual connection established. A hierarchical routing layer is provided within the software architecture of each processor within the computing device. The hierarchical routing layer abstracts the actual proximity of the network connectivity on the modem from the applications using proxy network interfaces. The hierarchical routing layers on each processor cooperate to identify a best network interface for an application network request. The routing layer enables response to an application request for a network interface in a simple manner regardless of whether the network interface is provided on the application host processor or another processor.
