  • Patent number: 11129109
    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: 20210120501
    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.

  • Patent number: 10931499
    Abstract: A user equipment may, based on a tuneaway, start suspend a first timer and/or deactivate a first counter and may, based on a tuneback, resume the first timer and/or activate the first counter. The first timer and first counter may be configured to be used to determine that a sufficiently large number of sufficiently closely timed beam failure indications have been received and, in response to that determination, initiate an access procedure. A user equipment may also identify an overlap of a timing of at least one radio access technology event and a timing of a tuneaway gap and may, based on the identified overlap of the timing of at least one radio access technology event and the timing of the tuneaway gap, modify the timing of the at least one radio access technology event or the timing of the tuneaway gap.

  • Publication number: 20210022171
    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.
