Abstract: Apparatuses for partially offloading processing from a user equipment (UE) to a cellular Radio Access Network (RAN) node are disclosed. An apparatus for a UE includes at least one processor configured to perform Transmission Control Protocol and Internet Protocol (TCP/IP) processing and offload only a portion of the TCP/IP processing to a cellular RAN node while maintaining TCP protocols running end-to-end between the UE and a remote host.

Abstract: Technology for a user equipment (UE), operable to generate an enhanced buffer status report (eBSR) is disclosed. The UE can identify packets for uplink transmission. The UE can filter the packets for transmission, to identify a number of small packets pending for transmission and a number of larger packets, relative to the small packets, that are pending for transmission in the uplink transmission. The UE can encode the eBSR for transmission to a next generation node B (gNB), wherein the eBSR includes information identifying the number of small packets pending for transmission. The UE can have a memory interface configured to send to a memory the number of small packets pending for transmission.

Abstract: An electronic device may have first and second rear-facing displays, a front-facing display, a cover at a front side overlapping the front-facing display, and an antenna that radiates through the cover. The cover may have a three-dimensional curvature. The device may have an inner chassis and an outer chassis. The antenna may include a radiating element and a ground trace on a flexible printed circuit. To maximize wireless performance of the antenna, the ground trace may be electrically coupled to as much conductive material in the vicinity of the antenna as possible. For example, the ground trace may be grounded to conductive structures in the front-facing display via a conductive cavity for the antenna, may be grounded directly to the outer chassis using conductive screws, and/or may be grounded directly to the inner chassis using conductive screws.

Abstract: This disclosure provides techniques for recovery techniques to address link failure in multi-hop backhaul relay network. For example, a central unit (CU) node receives, uplink transmissions originating from a user equipment (UE) via a backhaul relay including a first distributed unit (DU) node and a second DU node. The CU then receives a first UL status message associated with a link failure between the first DU node the second DU node. Then the CU generates a second UL status message indicating a sequence number (SN) of a lost packet caused by the link failure or a SN of a last successfully received packet before the link failure, and transmits the second UL status message to the first DU node.

Abstract: Embodiments of LWTP (long term evolution (LTE)/wireless local area network (WLAN) radio level integration Protocol) enhancements for reliable data radio bearer (DRB) switching are disclosed. A user equipment (UE) decodes a radio resource control (RRC) connection reconfiguration message, received from an evolved NodeB (eNB), the RRC connection reconfiguration message indicting switching DRBs from a first wireless transmission mode to second wireless transmission mode, and the RRC connection reconfiguration message including an uplink (UL) status report indicating a first missing UL sequence number, the UL status report being a UL LWIP status report. The UE causes reconfiguration of the UE according to the RRC connection reconfiguration message. The UE encodes, for transmission to the eNB, a RRC connection reconfiguration complete message. The UE encodes, for retransmission over the second wireless transmission mode, lost service data unit(s) (SDU) based on the UL status report.
