Abstract: 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.

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).

Abstract: 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.

Abstract: Aspects of the present disclosure describe transmitting data in wireless communications. A set of packets for transmission in a defined sequence can be received where the set of packets includes two or more packets. It can be detected that a packet, of the set of packets, is a prioritized packet type. The packet can be prioritized for transmission ahead of its order in the defined sequence based on the detection of the prioritized packet type. The packet can be transmitted ahead of its order in the defined sequence to an access point.

Abstract: 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.

Abstract: Certain aspects of the present disclosure provide techniques for uplink transport protocol acknowledgment shaping and downlink data shaping at a user equipment. A method that may be performed by the UE generally includes determining an allowed number of transport protocol acknowledgments to transmit in a transmission time interval (TTI); and transmitting one or more transport protocol acknowledgments in the TTI based, at least in part, on the determined allowed number of transport protocol acknowledgments. Another method that may be performed by the UE generally includes determining an allowed number of downlink data units to transmit in a TTI; and transmitting one or more data units in the TTI based, at least in part, on the determined allowed number of data units.
