摘要： 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.

摘要： 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.

摘要： Wireless communications systems and methods related to uplink buffer management are provided. In some aspects, a user equipment receives a synchronization acknowledgment message destined for a device tethered to the user equipment and transmitted by an application server at a network to which the user equipment is connected. In some aspects, the synchronization acknowledgment message includes an application server receiver window size indicating available buffer space in a receive buffer of the application server. The user equipment can modify the application server receiver window size in the received synchronization acknowledgment message prior to transmitting the received synchronization acknowledgment to the tethered device.

摘要： Certain aspects of the present disclosure relate to smart processing of wireless wide area network (WWAN) packets transmitted over wireless local area network (WLAN). According to certain aspects, a method for wireless communications by a user equipment (UE) capable of communicating via at least first and second radio access technologies (RATs) is provided. The method generally includes dynamically switching to a location, within the UE, as an anchor point for processing packets based, at least in part, on operating states of the first and second RATs and routing packets received via at least one of the first and second RATs to the dynamically switched location of the anchor point.

摘要： 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.

摘要： 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.

摘要： Aspects described herein relate to instructing, from a layer of a modem processor, a host processor to utilize an increased power consumption state for processing data from a network node. The instructing can be performed based on transmitting a signal to the network node and/or receiving signals from the network node, and at a time that allows the host processor to wake up before receiving data from the modem processor for processing.

摘要翻译： 在详细描述中公开的方面包括计算设备中的省电技术。 具体地，当数据由计算设备中的调制解调器处理器接收时，数据被保持直到调制解调器定时器期满。 然后，数据通过外围组件互连快速（PCIe）互连总线传送到计算设备中的应用处理器。 在接收到来自调制解调处理器的数据时，应用处理器通过PCIe互连总线将由应用处理器保存的数据发送到调制解调器处理器。 应用处理器还具有上行链路定时器。 如果在上行链路定时器到期之前没有从调制解调器处理器接收到数据，则应用处理器在上行链路定时器期满时将任何收集的数据发送到调制解调器处理器。 然而，如果从调制解调器处理器接收到数据，则重置上行链路定时器。
