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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first configuration to perform an uplink communication using a first frequency spectrum band. The UE may receive a second configuration to receive a downlink communication using a second frequency spectrum band. The UE may determine an interference caused by at least one of the first frequency spectrum band or the second frequency spectrum band. The UE may reroute, based at least in part on the determination, the uplink communication to a first uplink path or a second uplink path associated with the first frequency spectrum band. Numerous other aspects are provided.

Abstract: A configuration to adjust expiration of a PDCP reorder timer based on scheduler variations in dual connectivity. The apparatus receives, from a base station, a plurality of data packets. The plurality of data packets received from a first path and a second path. The apparatus detects at least one packet of the plurality of data packets at a PDCP is dropped based on an OOW. The apparatus determines a scheduling gap between the first path and the second path. The apparatus determines a timing relationship between the UE, the first path, and the second path. The apparatus determines consecutive sequence numbers associated with packets corresponding to the frame numbering sequence of the first path and the frame numbering sequence of the second path and a respective associated time. The apparatus adjusts a reorder timer based on the scheduling gap between the first path and the second path.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device such as a user equipment (UE) may receive a first control message that indicates a set of scheduled uplink communications, where the set of scheduled uplink communications include a set of transmission opportunities for transmitting one or more uplink messages. The UE may calculate a first duration between an availability of uplink data at the UE and a transmission opportunity of the set of transmission opportunities for transmitting the uplink data. The UE may then transmit a scheduling request for the uplink data based on the first duration being greater than a second duration, the second duration being either a duration between sending the scheduling request and receiving an uplink grant, or a latency threshold duration.

Abstract: A method and apparatus for receiving a notification of missing packets include receiving a set of data packets transmitted by a device and having a corresponding set of sequence numbers, identifying one or more data packets having corresponding sequence numbers that fall within the set of sequence numbers and are yet to be received, receiving an indication from the device that the one or more data packets will not be transmitted by the device, and processing the set of data packets without the one or more data packets in response to receiving the indication.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communications by a user equipment (UE) capable of establishing a split bearer involving at least primary and secondary radio link control (RLC) entities. The techniques generally include deciding, based on one or more conditions, whether to submit a Packet Data Convergence Protocol (PDCP) protocol data unit (PDU) to the primary RLC entity or the secondary RLC entity according to one or more rules and submitting the PDCP PDU to at least one of the primary or secondary RLC entities in accordance with the decision.

Abstract: Methods, systems, and devices for wireless communications are described for handling uplink grants that have associated uplink transmission that may exceed exposure limits. Exposure limits may be based on maximum permissible exposure (MPE) limits of millimeter wave transmissions and may be determined at a user equipment (UE) and provided to a base station. If the UE receives an uplink grant for a transmission in which an associated uplink transmission would exceed the exposure limits, the UE may drop the uplink transmission prior to forming a transport block, transmit control signaling to the base station to indicate the exposure limits at the UE, or combinations thereof.

Abstract: Wireless communication systems and methods related to radio link control (RLC) transmissions are provided. A first wireless communication device transmits a sequence of protocol data units (PDUs). The first wireless communication device receives a first reception status report for a first portion of a receiver buffer window used for receiving the sequence of PDUs from a second wireless communication device. The first wireless communication device receives a second reception status report for a second portion of the receiver buffer window, the second portion being different from the first portion, from the second wireless communication device.
