  • Patent number: 11405839
    Abstract: Various embodiments include methods and user equipment (UE) for mobile-terminated call handling when a latency-sensitive service (LSS) is active on the UE. Embodiments may include determining a radio access technology (RAT) used for a latency-sensitive service (LSS) currently active on the UE in response to receiving an MT call invitation and determining whether a latency-prone service command is received that includes service commands configured to change the determined RAT used for the LSS to another RAT likely to compromise the LSS. In response to determining that a latency-prone service command is received the MT call invitation may be rejected, but in response to determining that a latency-prone service command is not received, MT call alerting may be allowed.

  • Publication number: 20220239450
    Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. The UE may identify a first set of bands associated with a first subscription and a second set of bands associated with a second subscription. The UE may determine that at least a first band from the first set of bands and at least a second band from the second set of bands share a same set of radio frequency (RF) front-end resources. The UE may then refrain from communicating on a third band from the first set of bands while communicating on a remaining set of bands, where the third band may be associated with a secondary component carrier (SCC) of a multi-carrier communications scheme. Refraining from communicating on the third band may be based on the first and second bands sharing the RF front-end resources and the third band being associated with the SCC.

  • Patent number: 11363536
    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.

  • Publication number: 20220061085
    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.
