Abstract: A wireless device with dual connectivity may transmit split bearer traffic including a plurality of compressed data packets respectively to a first RLC entity of a first base station and a second RLC entity of a second base station and measure BLERs of the transmitted split bearer traffic. Based on the measured BLERs of the transmitted split bearer traffic, the wireless device may transmit uncompressed data packets to one or more of the first RLC entity or the second RLC entity. The wireless device may also reset a context memory and transmit the uncompressed data packets to the first RLC entity and the second RLC entity. A base station with dual connectivity may configure an LTE RLC entity with an RLC out-of-order delivery to deliver the received compressed data packets to an NR-PDCP entity without reordering the compressed data packets at the LTE RLC entity.

Abstract: In one aspect, a method of wireless communication includes determining a number of bytes in a compressed queue and a number of bytes in an uncompressed queue. The method also includes transmitting a buffer status report (BSR) indicating at least the number of bytes in the compressed queue. The method includes receiving an uplink grant indicating one or more uplink grant resources and a number of bytes allocated for the one or more uplink grant resources. The method also includes generating a transport block (TB) based on the uplink grant and the BSR and from data of at least the compressed queue, wherein the TB includes one or more compressed packets and one or more uncompressed packets. The method further includes transmitting a PUSCH transmission including the TB during an uplink grant resource of the one or more uplink grant resources. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may receive a set of packets having a sequential order. The UE may initiate a first packet data convergence protocol (PDCP) reordering timer based on a first time stamp corresponding to unsuccessful decoding of a first packet in the sequential order. The UE may then initiate, prior to the expiration of the first PDCP reordering timer, a second PDCP reordering timer. The second PDCP reordering timer may be based on a second time stamp corresponding to unsuccessful decoding of a second packet in the sequential order. In some cases, the UE may initiate the second PDCP reordering timer after expiration of the first PDCP reordering timer, but may decrease the duration of the second PDCP reordering timer.

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.
