摘要： Various aspects of the present disclosure generally relate to wireless communication. 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.

摘要： 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.

摘要： Wireless communication systems and methods related to Radio Link Control (RLC) status reporting are provided. A wireless communication device receives one or more radio link control (RLC) packet data units (PDUs) of a sequence of RLC PDUs. The wireless communication device determines missing RLC data PDUs in the sequence of RLC PDUs based on the received one or more RLC PDUs. The wireless communication device receives a first uplink (UL) grant. The wireless communication device transmits a first RLC status report including an indication of a first subset of the missing RLC PDUs less than all the missing RLC PDUs, the indication of the first subset of missing PDUs being based on a size of the first UL grant. The wireless communication device modifies a RLC status prohibit timer based on the transmitted first RLC status report indicating less than all the missing RLC PDUs.

摘要： 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.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a method may include simulating a degradation of at least one of a first wireless communication link with a network or a different second wireless communication link with the network based on detecting that a first set of one or more packets, which were received via the first wireless communication link with the network and were added to a packet buffer, and a second set of one or more packets, which were received via the different second wireless communication link with the network and were added to the packet buffer, satisfy a threshold occupancy of the packet buffer. Numerous other aspects are provided.

摘要： Aspects herein describe utilizing semi-persistent scheduling (SPS) resources in wireless communications. An indication to retransmit information for SPS resources can be received from an access point. It can be determined that a SPS activation for the SPS resources is not received from the access point. Based on this determination, one or more signals can be transmitted.

摘要： 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.

摘要： Certain aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for preparing data for transmission from a user equipment in a wireless communication system. In some embodiments, a method may limit memory access starts during a time interval to ensure that all memory access operations are completed with a transmission time interval.

摘要： Aspects of the present disclosure describe various techniques for handling data stall in wireless local area networks (WLANs). These techniques include, for example, a method in which wireless communications are switched at a wireless station from a first network device associated with a first radio access technology (RAT) (e.g., WLAN technology) to a second network device associated with a second RAT (e.g., wireless wide area network (WWAN) technology). The wireless station may then monitor network devices associated with the first RAT, including the first network device. The wireless station may filter results from the monitoring based at least in part on one or more threshold value and identify, based on the filtered results, one of the network devices as suitable for the wireless communications. The wireless communications may then be switched at the wireless station from the second network device to the one network device identified as suitable for the wireless communications.
