Abstract: In some examples, the method and apparatus may comprise dynamically scaling the packet compression procedures based on available system resources. For example, as the available resource capacity (e.g., processing power, bus bandwidth and/or memory) decreases, aspects of the present disclosure may dynamically adjust the usage of the packet compression procedures on one or more data packets to maximize available resources and achieve optimal compression gains.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive radio link control (RLC) protocol data units (PDUs) within a receive window. Additionally, the UE may receive an uplink grant indicating a set of resources. Based on the set of resources, the UE may transmit a STATUS PDU including a single field that indicates a sequence number (SN) of a first PDU the UE received but unsuccessfully decoded within the receive window. Alternatively, the UE may transmit STATUS PDU segments based on which PDUs the UE receives and the quantity resources in the uplink grant. In some cases, the UE may transmit a STATUS PDU that includes a first field to indicate an SN of a first PDU the UE received but unsuccessfully decoded within the receive window, and one or more offset fields that indicate SNs of respective PDUs subsequent to the first PDU.

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: A receiving device re-establishing a packet data convergence protocol (PDCP) entity. The receiving device resets a robust header compression (ROHC) context. The receiving device receives packet retransmissions having header compression based on the ROHC. The receiving device performs decompression of the packet retransmissions. The receiving device discards duplicate packets after performing the decompression of the packet retransmissions.

Abstract: Apparatus, methods, and computer-readable media for facilitating prioritizing PDCP retransmission and/or control information in dual connectivity scenarios are disclosed herein. An example method for wireless communication at a first network node includes receiving PDUs for transmitting to a second network node while operating in a dual connectivity mode associated with a first RLC leg and at least a second RLC leg, the PDUs associated with at least one of control information or retransmission data. The example method also includes transmitting first scheduling information via the first RLC leg and transmitting second scheduling information via the second RLC leg based on the PDUs being associated with at least one of the control information or the retransmission data. The example first network node may include a UE or a base station.

Abstract: A method of wireless communication, by a user equipment (UE), includes setting up a secondary cell group (SCG) with a second radio access technology (RAT) that differs from a first RAT associated with a master cell group (MCG). The method also includes communicating wirelessly via the secondary cell group and the master cell group. The method further includes predicting a radio link failure (RLF) for the secondary cell group based on multiple inputs to a machine learning model. The method still further includes routing data transmission from the secondary cell group to the master cell group, after predicting the SCG RLF.

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: Certain aspects of the present disclosure provide techniques for sending uplink control information. A method that may be performed by a user equipment (UE) includes receiving an uplink grant for transmission on a plurality of physical uplink shared channels (PUSCHs), the plurality of PUSCHs being located on different component carriers (CCs); identifying one or more PUSCHs of the plurality of PUSCHs on which uplink control information (UCI) can be transmitted in a slot; assigning PUSCH data to the one or more identified PUSCHs on which the UCI can be transmitted before assigning PUSCH data to remaining PUSCHs of the plurality of PUSCHs; and transmitting the UCI and the PUSCH data in the slot on the assigned PUSCHs.
