Abstract: A wireless communication device is described. The wireless communication device includes a memory and a processor in electronic communication with the memory. The processor is configured to determine a packet data convergence protocol (PDCP) packet count corresponding to a last radio link control (RLC) packet received in-sequence. The processor is also configured to detect a missing PDCP packet based on a comparison of the PDCP packet count and a sequence number of a last PDCP packet received in-sequence.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a method may include simulating a degradation of at least one of a first wireless communication link with a network or a different second wireless communication link with the network based on detecting that a first set of one or more packets, which were received via the first wireless communication link with the network and were added to a packet buffer, and a second set of one or more packets, which were received via the different second wireless communication link with the network and were added to the packet buffer, satisfy a threshold occupancy of the packet buffer. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure relate to optimization of packet processing when packets are received out of order in sequence. For example, a user equipment (UE) may determine whether a difference between a sequence number of a first packet and a sequence number of a second packet received subsequent to receiving the first packet exceeds a sequence jump threshold. The UE may disregard the second packet from processing in response to at least determining that the difference is greater than the sequence jump threshold. The UE may receive and process a plurality of packets respectively associated with a plurality of sequence numbers that are greater than the sequence number of the first packet and less than the sequence number of the second packet.

Abstract: Methods, systems, and devices for wireless communications are described. A receiving device may receive, at a first operational layer of the receiving device, one or more protocol data units (PDUs) within a set of PDUs. The receiving device may identify, at a second operational layer of the receiving device, a sequence gap associated with a missing PDU from the set of PDUs, the first operational layer being a lower operational layer of the receiving device than the second operational layer. The receiving device may determine, at the second operational layer, that a triggering condition associated with the missing PDU has occurred. The receiving device may provide, by the second operational layer and based at least in part on the triggering condition occurring, an indication to update a reception buffer of the first operational layer to a last received protocol data unit of the set of PDUs.
