Abstract: Aspects of the present disclosure provide mechanisms for fast hyper frame number (HFN) resynchronization of Packet Data Convergence Protocol (PDCP) Protocol Data Units (PDUs). A wireless communication device (e.g., a PDCP entity at a wireless communication device) can calculate a current PDCP count of a current PDCP PDU of a plurality of PDCP PDUs received from a radio link control (RLC) sublayer based on a PDCP sequence number (SN) of the current PDCP PDU and an HFN of a first missing PDCP PDU after a successfully received PDCP PDU. The PDCP count may be calculated using the HFN of the first missing PDCP PDU in response to a gap between the PDCP count of the first missing PDCP PDU and the actual PDCP count of the current PDCP PDU being greater than a PDCP window size.

Abstract: This disclosure provides systems, methods and apparatuses for a high priority route selection descriptor (RSD) selection timer. A protocol data unit (PDU) session may be established for an application associated with a user equipment (UE). If the PDU session is associated with a lower RSD priority than the highest RSD priority for the application, the UE may initiate an RSD selection timer. After expiration of the RSD selection timer, the UE may try to establish another PDU session for the application with the highest RSD priority for the application. If another PDU session with the highest RSD priority is accepted, the UE may release the initial PDU session with the lower RSD priority and establish a new PDU session with the highest RSD priority. Such implementations may increase data rates, quality of service, and reliability for the application, decrease latency of the application, or decrease power consumption of the UE.

Abstract: Certain aspects of the present disclosure provide techniques for packet buffering. A method that may be performed by a receiving node includes dynamically determining one or more time durations to buffer packets. The one or more time durations can be different than a time duration of a configured timer for buffering the packets. The receiving node may input one or more parameters to a machine learning algorithm and obtain, as output of the machine learning algorithm based on the input one or more parameters, one or more time durations to buffer packets. The receiving node buffers packets for the determined one or more time durations. The receiving node may use machine learning to dynamically determine the one or more time durations to buffer packet. The buffering may be at a radio link control (RLC) reassembling buffer and/or a packet data convergence protocol (PDCP) buffer.

Abstract: A delta configuration is signaled for handover of a wireless communication device (e.g., a user equipment, UE) from a first form of connectivity to a second form of connectivity. For example, a UE with master cell group (MCG) connectivity may be handed-over to multiple radio access technology-dual connectivity (MR-DC). In some examples, a UE with standalone (SA) connectivity may be handed-over to non-standalone (NSA) connectivity (e.g., dual connectivity). In conjunction with this handover the UE may be signaled as to whether the UE is to reuse a configuration from the first connectivity mode during the second connectivity mode.

Abstract: Aspects of the present disclosure describe transmitting data in wireless communications. A set of packets for transmission in a defined sequence can be received where the set of packets includes two or more packets. It can be detected that a packet, of the set of packets, is a prioritized packet type. The packet can be prioritized for transmission ahead of its order in the defined sequence based on the detection of the prioritized packet type. The packet can be transmitted ahead of its order in the defined sequence to an access point.

Abstract: In device-to-device (D2D) communication in a licensed spectrum, selection of a transmit pool and distribution of codes to be transmitted to the transmit pools for more efficient transmission is desired, for a given period. The apparatus may a user equipment (UE) for D2D communication in a licensed spectrum. The UE sets a discovery epoch to a shortest discovery period among discovery periods of a plurality of transmit resource pools, each transmit resource pool of the plurality of transmit resource pools associated with a respective frequency. The UE estimates a channel utilization of each transmit resource pool of the plurality of transmit resource pools based on one or more previous transmissions on each transmit resource pool of the plurality of transmit resource pools. The UE selects a transmit resource pool among the plurality of transmit resource pools for a D2D transmission within the discovery epoch based on the estimated channel utilizations.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for improving buffer size setting for one or more buffer status reports, such as one or more extended buffer status reports (eBSRs) in a wireless communication system. According to certain aspects, a method is provided herein for wireless communications performed by a user equipment (UE). The method generally includes determining a first amount of data stored in a buffer at the UE; and if the first amount of the data satisfies (e.g., is equal to or greater than) a threshold, sending a first BSR indicating a second amount of buffered data at the UE greater than the first amount. As a result, the UE may be scheduled by the base station for a greater amount uplink resources for transmitting the buffered data.
