Abstract: Methods, systems, and devices for wireless communications are described. In aspects, a wireless device such as a user equipment (UE) may identify an amount of acknowledgement (ACK) reduction associated with an applications processor. The amount of ACK reduction may be determined based on a communication from the applications processor, or an ACK frequency in a group of packets received from the applications processor. The UE may determine whether to modify an ACK management scheme (e.g., a transmission control protocol (TCP) ACK coalescing scheme) based at least in part on the amount of ACK reduction associated with the applications processor. The UE may modify the ACK management scheme. The UE may transmit ACKs in accordance with the modified ACK management scheme. Numerous other aspects are provided.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus transmits, by a user equipment (UE), a packet to a network entity, while the UE is in a radio resource control (RRC) connected mode. The apparatus determines an acknowledgment (ACK) is absent for the transmitted packet. The apparatus determines to retransmit the packet based at least on whether the UE is in the RRC connected mode or on a type of the packet, upon determining the ACK is absent. The apparatus may determine to retransmit the packet by retransmitting the packet upon determining the UE is in the RRC connected mode. The apparatus may determine to retransmit the packet by suppressing retransmission of the packet upon determining that the UE is not in the RRC connected mode.

Abstract: Techniques for deriving a WLAN security context from an existing WWAN security context are provided. According to certain aspects, a user equipment (UE) establishes a secure connection with a wireless wide area network (WWAN). The UE may receive from the WWAN an indication of a wireless local area network (WLAN) for which to derive a security context. The UE then derives the security context for the WLAN, based on a security context for the WWAN obtained while establishing the secure connection with the WWAN and establishes a secure connection with the WLAN using the derived security context for the WLAN. This permits the UE to establish a Robust Security Network Association (RSNA) with the WLAN while avoiding lengthy authentication procedures with an AAA server, thus speeding up the association process.

Abstract: Techniques for wireless communication at a user equipment (UE) are described. One method includes receiving, from a first access point using a first radio access technology (RAT), a configuration associated with a logical traffic connection, in which the configuration includes at least one parameter for communicating data associated with the logical traffic connection via a second access point associated with a second RAT; determining a buffer reporting value associated with the logical traffic connection based at least in part on a total amount of data buffered in a packet data convergence protocol (PDCP) queue associated with the logical traffic connection and the at least one parameter; and transmitting a buffer status report (BSR) including the buffer reporting value to the first access point.

Abstract: Methods, systems, and devices for wireless communication are described. Semi-persistent scheduling (SPS) configurations that enable uplink transmissions during different transmission time intervals (TTIs) may be used. For example, a base station may configure SPS for a set of TTIs, where the configuration may include a periodicity between shortened TTIs (sTTIs) (e.g., two-symbol, three-symbol, seven-symbol TTIs, etc.) that may be used by a user equipment (UE) for uplink transmissions. The base station may signal the SPS configuration to the UE, and the UE may then identify locations of TTIs for use in SPS transmissions. For instance, the UE may identify the location of a set of sTTIs that are designated for SPS and that occur at a certain periodicity indicated by the configuration. Upon identifying the TTI locations, the UE may transmit uplink data during one or more of the identified TTIs in accordance with the periodicity.

Abstract: Methods and apparatus for offloading traffic from a cellular network to a wireless local area network (WLAN) are described. One example method generally includes receiving, from a serving base station, a request to measure one or more WLAN access points (APs), determining one or more metrics for the WLAN APs, comparing the metrics for the WLAN APs to a threshold, and reporting metrics for at least a first AP of the WLAN APs if the metrics for the first AP exceed the threshold.

Abstract: A base station may transmit a grant to user equipment (UEs), indicating uplink resources for transmission of pending data at a UE. Uplink resources may include uplink resources associated with transmission time intervals (TTIs) and/or shortened TTIs (sTTIs). A UE may identify pending data associated with a data type (e.g., low latency data, internet traffic, etc.) and transmit a scheduling request (SR) for a grant of uplink resources. The data type of the pending data (e.g., the logic channel group identification (LCG ID) associated with a buffer status) may be indicated such that uplink resources may be granted to the UE to reduce latency. In some aspects, the SR may indicate uplink resources associated with sTTIs. Further, the UE may prioritize pending data and buffer status reports (BSRs) associated with other data within the received grant.

Abstract: Aspects of the present disclosure describe various techniques for handling data stall in wireless local area networks (WLANs). These techniques include, for example, a method in which wireless communications are switched at a wireless station from a first network device associated with a first radio access technology (RAT) (e.g., WLAN technology) to a second network device associated with a second RAT (e.g., wireless wide area network (WWAN) technology). The wireless station may then monitor network devices associated with the first RAT, including the first network device. The wireless station may filter results from the monitoring based at least in part on one or more threshold value and identify, based on the filtered results, one of the network devices as suitable for the wireless communications. The wireless communications may then be switched at the wireless station from the second network device to the one network device identified as suitable for the wireless communications.

Abstract: Aspects relate to a priority mechanism for prioritizing network identifiers, for example SSIDs. As described herein, a UE may obtain one or more network identifier sets, each of the one or more network identifier sets having one or more network identifiers for a first RAT and a priority level, determine one or more of the network identifier sets that are under control of a second RAT, and after the determining, manage connections to the first RAT based, at least in part, on the priority level of the network identifier sets.
