Abstract: Methods and apparatuses for serving cell management of a user equipment (UE) are presented. Particularly, methods and apparatuses are presented for suppressing a serving cell change based on a speed of the UE. For instance, an example method is presented for serving cell management that may include determining that a serving cell change condition exists for an initiation of a serving cell change for the UE, wherein the serving cell change comprises changing a serving cell of the UE from a macro cell to a low power cell. In addition, the example method may include obtaining a speed of the UE and suppressing the initiation of the serving cell change based on the speed of the UE.

Abstract: Aspects directed towards Quality of Service (QoS) flow remapping are disclosed. In an example, upon detecting a mapping reconfiguration of a first QoS flow from a first data radio bearer (DRB) to another DRB, a Service Data Adaptation Protocol (SDAP) control protocol data unit (PDU) is generated indicating that a final SDAP data PDU associated with the first QoS flow has been transmitted on the first DRB. The SDAP control PDU is then transmitted via the first DRB. In another example, upon detecting a mapping reconfiguration of a first QoS flow from a first DRB to another DRB, an end marker parameter is set in an SDAP header of a first SDAP data PDU received from an upper layer after the mapping reconfiguration indicating that the first SDAP data PDU is a final SDAP data PDU associated with the first QoS flow transmitted on the first DRB.

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: 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 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 provide techniques to enable enhanced machine type communication (s) (eMTC) and/or narrowband Internet-of-Things (NB-IoT) devices to transition to idle mode after releasing a connection, such as a radio resource control (RRC) connection, more quickly than with previously known techniques. An example method includes determining, based on an indication received in a narrowband signal on a narrowband region of a bandwidth comprising a plurality of narrowband regions, whether to wait for a delay period, determined based on a configuration received from a network entity, before releasing a radio resource control (RRC) connection and releasing the RRC connection at a time in accordance with the determination.

Abstract: Aspects described herein relate to wireless communications. Protocol data units (PDUs) can be received at a network layer from one or more transmitting nodes using a link associated with each respective transmitting node. One or more missing PDUs can be detected based, at least in part, on sequence numbers of the received PDUs. A timer can be started based on the detection of the one or more missing PDUs. In response to expiration of the timer, and without receiving the one or more missing PDUs before the expiration of the timer, a lower network layer can be notified that the one or more missing PDUs are received to prevent attempted transmitting/retransmitting or other processing of the one or more missing PDUs.

Abstract: A method, an apparatus, and a processor-readable storage medium for wireless communication are provided. A transmitter transmits data packets to a receiver, encodes the data packets to generate parity packets, stores the parity packets in a retransmission buffer, receives information from the receiver indicating that a data packet was not correctly decoded, and transmits to the receiver the parity packets stored in the retransmission buffer for recovering the data packet not correctly decoded without retransmitting the data packet not correctly decoded. The transmitter may further retransmit to the receiver the parity packets. The transmitted data packets may be encoded at a medium access control (MAC) layer of the transmitter. The retransmission buffer may be located at a radio link control (RLC) layer or a packet data convergence protocol (PDCP) layer of the transmitter. A reordering buffer at the receiver may be located at the RLC layer or PDCP layer.
