Abstract: Methods, systems, and devices for wireless communication are described. A serving base station may determine a handover loss metric associated with a UE that is a candidate for handover. The handover loss metric may be based on connection parameters associated with the serving base station and a target base station, respectively. The serving base station may identify, based on the handover loss metric, a type of handover procedure to perform. The serving base station may perform the handover procedure of the UE to the target base station according to the identified handover type.

Abstract: Methods, systems, and devices for wireless communications are described. One example method for wireless communications at a user equipment (UE) includes detecting a radio link failure (RLF) condition for a connection between the UE and a network over a first cell group and determining, in response to detecting the RLF condition, whether an air interface resource allocation is available for a signaling radio bearer (SRB) between the UE and the network over another cell group. The method also includes selecting, based at least in part on the determination, one of a plurality of RLF procedures. In some examples, the UE may select a first RLF procedure that fully releases radio resources when no SRB is available and a different, second RLF procedure that partially when an SRB is available between the UE and the network over a second cell group.

Abstract: Aspects described herein relate to managing service data flows and corresponding data radio bearers. An indication of a binding between a service data flow and a data radio bearer with an access point can be received. The data radio bearer for binding to the service data flow can be determined as either an existing data radio bearer that supports one or more quality-of-service (QoS) parameters of the service data flow or a new data radio bearer to support one or more data flows of the service data flow. An existing data radio bearer can be modified or a new data radio bearer can be established based on the determination. Based on the binding, a packet can be transmitted using the data radio bearer based at least in part on classifying the packet as related to the service data flow.

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: A wireless device may receive a radio link control (RLC) protocol data unit (PDU) from a lower layer (e.g., from a media access control (MAC) layer) when processing communications (e.g., packets) received from another wireless device. The receiving wireless device may identify that the PDU is an RLC service data unit (SDU) segment based at least in part on an indication corresponding to a sequence number associated with the RLC SDU segment. The receiving wireless device may then determine that the RLC SDU segment is received out of order based on previously received PDUs or previously received RLC SDU segments, and initiate a reassembly timer based on the out of order determination for the RLC SDUs. If the remaining RLC SDU segments (e.g., that complete the RLC SDU) are received before reassembly timer expires, the wireless device may reassemble the RLC SDU to be passed to a higher layer.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications system may support multi-connectivity for a user equipment (UE) with multiple distributed units (DUs) under one central unit (CU), the DUs and the CU belonging to a base station. The UE may establish radio resource control (RRC) connections with multiple cell groups corresponding to multiple DUs under the CU. The UE may transmit measurement reports that provide measurement information for cells in proximity to the UE. The UE may maintain a set of active cell groups and a set of inactive cell groups. In some cases, one or more cell groups may be identified as controlling cell groups used to transmit control information. In some examples, the UE may replicate an uplink packets and transmit the uplink packet and replicates on multiple cell groups. In some cases, the UE may aggregate an uplink transmission among multiple cell groups.

A packet data protocol convergence protocol (PDCP) entity of a transmit- ting device may duplicate a received packet to form a set of copied packets. Each packet in the set of copied packets may include the information of the received packet. Each packet of the set of copied packets may be transmitted using a different radio link control 0 (RLC) entity. Procedures are described for configuring duplication bearers. Procedures are described for activating or deactivating packet duplication. Procedures are described for handling RLC entities at deactivation. Procedures are described for discarding some duplicate packets after a packet has been successfully decoded by a receiving device. Procedures are described for delaying transmission of duplicate packets to improve effi- FIG. 3A , 05 cient use of communication resources. Procedures are described for buffer status report (BSR) reporting for duplication bearers.

Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a transmitting device may identify a Radio Link Control (RLC) service data unit (SDU) to be transmitted to a receiving device. In some cases, the transmitting device may not have access to sufficient resources to transmit the entire RLC SDU. As such, the transmitting device may segment the RLC SDU into RLC SDU segments, and the transmitting device may transmit the RLC SDU segments to the receiving device. If an RLC layer at the receiving device receives one or more RLC SDU segments out of sequence, the RLC layer may initiate a reassembly (or reordering) timer. The RLC layer may reassemble the successfully received RLC SDU segments to be passed to upper layers. Once the timer expires, the RLC layer may declare that the missing RLC SDU segments are lost.
