  • Publication number: 20230145079
    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.

  • Patent number: 11627490
    Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may associate, at a first protocol layer, a first sequence number to a data packet to perform integrity protection on at least a portion of the data packet. The transmitting device may associate, at the first protocol layer, a second sequence number to the data packet for wireless transmission to a receiving device. The transmitting device may indicate an offset between the first sequence number and the second sequence number in the data packet.

  • Publication number: 20230090373
    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.

  • Patent number: 11611900
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a trigger for transmitting a buffer status report (BSR). The UE may transmit, to a base station, a long BSR for a single logical channel group (LCG) with data to be transmitted based at least in part on at least one of a determination that a current buffer size for the single LCG is greater than a maximum buffer size indication in a short BSR or a determination that a current achievable uplink throughput using the short BSR is less than a configured uplink throughput. Numerous other aspects are described.

  • Patent number: 11601880
    Abstract: A UE may, responsive to detecting a power-related condition, send a message to induce the master node to release the secondary node. Such a message can include a message reporting a radio link failure of the secondary node, or, if a channel quality indicator is configured for at least some of the secondary cells of the secondary node, reporting a low CQI value so that the network can cease scheduling on such cells. Alternatively, in a carrier aggregation (CA) mode, with the UE connected to a single node comprising a primary cell and one or more secondary cells, the UE may not control which and how many secondary cells with which it communicates. In such a scenario, if such secondary cells are configured for channel quality indicator reporting, the UE may report a low CQI value so that the node will cease scheduling data on such cells.

  • Patent number: 11601891
    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.

  • Publication number: 20230047375
    Abstract: Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE). The UE starts a first timer (such as a discontinuous reception (DRX) hybrid automatic repeat request (HARQ) round-trip-time (RTT) timer), after sending an uplink (UL) data transmission to a network entity. The UE then starts a second timer (such as a DRX retransmission timer) when the first timer expires. The UE then determines whether to wake up or sleep for a duration of the second timer based on a prior block error rate (BLER).

  • Publication number: 20230016194
    Abstract: Aspects of the present disclosure provide example apparatus, methods, processing systems, and computer readable mediums implementing techniques for modifying a configuration of a radio bearer based on a request for quality of service (QoS) for a communication flow. In aspects, a user equipment (UE) receives a request for a QoS for a communication flow and maps the communication flow to a radio bearer based on a downlink map. The UE is configured to communicate over a number of radio bearers. The downlink map associates one or more communication flows to one or more of the number of radio bearers. The UE then modifies a configuration of the radio bearer based on the request for the QoS. During operation, the UE receives one or more downlink packets on the radio bearer and processes the one or more downlink packets according to the QoS.
