The UE may transmit, based at least in part on the transmit configuration, a second communication during at least a portion of an OFF duration of the uplink transmission interval configuration, wherein the transmit configuration indicates a first amount of energy for the first communication based at least in part on the first communication being associated with the first group of logical channels and a second amount of energy for the second communication based at least in part on the second communication being associated with a second group of logical channels.

Abstract: This disclosure provides systems, methods and apparatuses for user equipment (UE)-side and network-side mitigation of intermodulation (IM) interference, such as IM interference associated with multi-radio access technology communications. For example, the UE or a base station may detect an IM interference condition, and may perform an IM mitigation action based on detecting the IM interference condition. The UE may reduce an uplink transmit power so that IM interference on the downlink is reduced. Various base station IM mitigation actions are provided, such as suspending scheduling on a bearer, using a scheduling pattern that avoids concurrent transmission, reducing a maximum transmit power of an uplink grant of the UE, allocating resource blocks or bandwidth parts that do not overlap with an IM interference resource, changing a secondary cell group channel to a non-interfering channel, releasing a secondary cell group channel, deactivating a carrier, or changing a channel of the UE.

Abstract: Certain aspects of the present disclosure provide techniques for channel quality indicator (CQI)-based downlink buffer management as well as mitigating throughput loss in dual connectivity with multi-SIM. A method that may be performed by a user equipment (UE) includes communicating with a first network on a first channel using a first technology, determining whether a tune-away associated with the first technology will occur, and outputting, for transmission to the first network on a second channel using a second technology, a channel quality indicator (CQI) report corresponding to the second channel if the tune-away will occur, wherein the CQI report indicates a lower CQI for the second channel than a current CQI for the second channel.

In some aspects, a wireless receiver may receive, from a radio bearer configured to use header compression and at a lower layer of the wireless receiver, a plurality of packets based at least in part on the header compression, wherein the lower layer receives the plurality of packets in an out-of-order sequence. The wireless receiver may deliver, from the lower layer of the wireless receiver to a higher layer of the wireless receiver, the plurality of packets, after header decompression according to the out-of-order sequence, based at least in part on at least one threshold. Numerous other aspects are provided.

Abstract: Aspects directed towards Quality of Service (QoS) flow remapping are disclosed. In an example, upon detecting a mapping reconfiguration of a first QoS flow from a first data radio bearer (DRB) to another DRB, a Service Data Adaptation Protocol (SDAP) control protocol data unit (PDU) is generated indicating that a final SDAP data PDU associated with the first QoS flow has been transmitted on the first DRB. The SDAP control PDU is then transmitted via the first DRB. In another example, upon detecting a mapping reconfiguration of a first QoS flow from a first DRB to another DRB, an end marker parameter is set in an SDAP header of a first SDAP data PDU received from an upper layer after the mapping reconfiguration indicating that the first SDAP data PDU is a final SDAP data PDU associated with the first QoS flow transmitted on the first DRB.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a modem of a user equipment (UE) and a data source, such as an application processor or a tethered client, may support for flow control enforcement per service flow. For example, the modem may transmit, to the application processor, a first flow control command for a first data traffic including non-prioritized data. The application processor, based on the first flow control command, may transmit, to the modem, the first data traffic including the non-prioritized data according to the first flow control command while also transmitting a second data traffic including prioritized data without flow control. The modem and the application processor may support such selective flow control enforcement based on a priority of a service flow based on maintaining multiple buffers at the modem or based on defining multiple thresholds of one buffer associated with triggering flow control.

Abstract: Techniques for wireless communications are described. Control information used to preschedule communication resources may be received and communications may be performed based on the control information using a prescheduling technique. A scheduling type used for the control information may be determined using configuration information, an indication included in the control information, or both. A wireless device that is prescheduled communication resources may not start or not restart an inactivity timer based on the received control information. Also, a wireless device that is prescheduled communication resources may not start a retransmission timer based on the received control information. Additionally, a wireless device that is prescheduled communication resources may also refrain from transmitting a scheduling request based on a duration until a next instance of prescheduled communication resources is expected to occur.

Abstract: A base station may transmit a grant to user equipment (UEs), indicating uplink resources for transmission of pending data at a UE. Uplink resources may include uplink resources associated with transmission time intervals (TTIs) and/or shortened TTIs (sTTIs). A UE may identify pending data associated with a data type (e.g., low latency data, internet traffic, etc.) and transmit a scheduling request (SR) for a grant of uplink resources. The data type of the pending data (e.g., the logic channel group identification (LCG ID) associated with a buffer status) may be indicated such that uplink resources may be granted to the UE to reduce latency. In some aspects, the SR may indicate uplink resources associated with sTTIs. Further, the UE may prioritize pending data and buffer status reports (BSRs) associated with other data within the received grant.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for managing scheduling requests (SRs) in a user equipment (UE) that supports a split data radio bearer (DRB). In some aspects, the UE may trigger a first SR for a first communication link and a second SR for a second communication link in response to determining that a first amount of data in the UE data buffer is greater than a first threshold. The UE may transmit the first SR to a first base station (BS) via the first communication link. Prior to transmission of the second SR, the UE may determine whether a second amount of data in the UE data buffer is less than a second threshold. The UE may cancel the second SR in response to the second amount of data in the UE data buffer being less than the second threshold.

Abstract: In an embodiment, a UE receives a first uplink grant for a first RAT (e.g., 5G NR) and a second uplink grant for a second RAT (e.g., LTE). In one embodiment, the UE schedules an uplink transmission on the first RAT (e.g., by selectively dropping the uplink transmission on particular resource blocks) so as to manage an amount of time that is based on concurrent uplink transmissions on both the first and second RATs are performed. In another embodiment, the UE establishes a first period of time where a BSR transmitted by the UE on the first RAT is adjusted based on scheduling of concurrent uplink multi-RAT transmissions, and a second period of time where no BSR is transmitted by the UE on the first RAT based where concurrent uplink transmissions on both the first and second RATs are not permitted to be scheduled.

Abstract: Aspects are directed towards activating out-of-order delivery (OOOD) on a user equipment (UE). An application programming interface (API) on the UE may set one or more configuration parameters for IP flows from the wireless network.

The UE may then activate OOOD for the IP flows from the wireless network that meet the one or more configuration parameters.
