Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate on a first set of carriers in a first frequency range (FR) and a second set of carriers in a second FR. The UE may detect a radio link control (RLC) discontinuity on at least one of the first set of carriers or the second set of carriers. The UE may identify one or more FRs, of the first FR and the second FR, in which the RLC discontinuity occurred. The UE may transmit an RLC status report based at least in part on the identified one or more FRs. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may initiate a first service associated with a first subscriber identity module (SIM) of the UE and a first priority. The UE may initiate a second service associated with a second SIM of the UE and a second priority. The UE may switch the first priority and the second priority during at least part of the first service or the second service. The UE may perform a communication in accordance with at least one of the first priority or the second priority. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first configuration to perform an uplink communication using a first frequency spectrum band. The UE may receive a second configuration to receive a downlink communication using a second frequency spectrum band. The UE may determine an interference caused by at least one of the first frequency spectrum band or the second frequency spectrum band. The UE may reroute, based at least in part on the determination, the uplink communication to a first uplink path or a second uplink path associated with the first frequency spectrum band. Numerous other aspects are provided.

Abstract: 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.

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: 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.

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: 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.
