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: Systems and method of embodiments herein operate to conserve battery power of user equipment (UE). Embodiments determine whether waking up a UE receiver would be beneficial and based on the determination, the UE either wakes up the receiver or returns to sleep. Embodiments determine whether to wake up the receiver by performing pre-wake up (PWU) operation which either wakes up the receiver in a low power mode or wakes up the UE's wake up receiver. It may be determined whether a wake up (WU) signal is received during a PWU stage. If a WU signal is received during the PWU stage the UE may perform a full wake up of the receiver. If a WU signal is not received the UE may return to idle mode. In embodiments, WU (Wake Up) DRX cycles are supplemented with a Full DRX (Discontinuous Reception) cycle.

Abstract: Methods, systems, and devices for wireless communications are described in which uplink timelines may be reduced by initiating, at a user equipment (UE), uplink transmission processing prior to receipt of an uplink grant for an uplink communication. A UE may identify one or more uplink transmission parameters associated with a reduced uplink transmission timeline for an uplink communication, and use the uplink transmission parameters to initiate processing of the uplink communication prior to receiving an uplink grant from a base station. The uplink transmission parameters may allow for packet preparation at a higher layers (e.g., at a medium access control (MAC) layer or radio link control (RLC) layer) to be started or completed prior to receipt of the uplink grant.

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: In an aspect, a UE determines whether there is an overlap between a first uplink transmission channel allocated for transmission of a first uplink transmission and a second uplink transmission channel allocated for transmission of second uplink transmission. The UE generates a combined uplink transmission payload in response to a determination that there is the overlap, wherein the combined uplink transmission payload includes at least a portion of the first uplink transmission and at least a portion of the second uplink transmission. The UE transmits the combined uplink transmission payload on either the first uplink transmission channel or the second uplink transmission channel. A base station receives the combined uplink transmission payload transmitted by the UE.

Abstract: Certain aspects of the present disclosure relate to uplink preemption in certain systems, such as new radio (NR) systems, supporting carrier aggregation (CA) and/or multi-connectivity modes. A method for wireless communication, that can be performed by a user equipment (UE), generally includes receiving a resource assignment scheduling the UE for uplink transmission. The UE receives an indication to preempt uplink transmission on a portion of the assigned resources and determines whether to transmit on the remaining assigned resources. A method that can be performed by a base station (BS) generally includes receiving an indication from one or more UEs indicating, for each of a plurality of band combinations, a capability of the UE to transmit on a band when transmission on another band in the band combination is preempted and scheduling the one or more UEs for uplink transmission based on the indication.

Abstract: Power control in new radio (NR)-to-NR dual connectivity communications is disclosed. A UE, compatible for NR-to-NR dual connectivity, may receive a transmit power configuration and a power allocation configuration. The transmit power configuration identifies the designated reserved power for each of the cell groups participating in the dual connectivity communication. The power allocation configuration identifies to the UE whether to operate access to excess transmission power by either mode 1 rules, which may introduce phase discontinuity into ongoing transmissions, or mode 2 rules, which use a look-ahead functionality to trigger joint determination and allocation of transmission power among known uplink transmissions over a given transmission duration. After the determined transmission power allocation has been made, the UE transmits the dual connectivity transmissions according to the determined power.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently determining whether to transmit an uplink transmission scheduled by a semi-static grant or a dynamic uplink transmission scheduled by a dynamic grant when the dynamic uplink transmission conflicts with the uplink transmission scheduled by the semi-static grant. In particular, if a user equipment (UE) determines that a dynamic grant is received within a threshold time before an uplink transmission scheduled by a semi-static grant, the UE may transmit the uplink transmission scheduled by the semi-static grant and refrain from transmitting the dynamic transmission. Alternatively, if the UE determines that a dynamic grant is received in advance of a threshold time before an uplink transmission scheduled by a semi-static grant, the UE may transmit the dynamic transmission and refrain from transmitting the uplink transmission scheduled by the semi-static grant.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first slot format configuration for a first serving cell for a set of transmission time intervals (TTIs) including a first TTI and receive a second slot format configuration for the first serving cell for the first TTI which is different from the first slot format configuration. The UE may determine, based on priorities of the slot format configurations, a first communication direction for the first serving cell for the first TTI. The UE may identify, for a second serving cell for the first TTI, a second communication direction indicated by one or more slot format configurations for the second serving cell. The UE may determine whether to communicate on the second serving cell for the first TTI according to the one or more slot format configurations for the second serving cell.

Abstract: Methods, systems, and devices for wireless communications for determining a minimum time gap between an received downlink message and transmission of an uplink message in response to the received downlink message. In some cases, a user equipment (UE) may receive a downlink message to perform a random access procedure. The UE may determine a minimum time gap based on an uplink transmission preparation time. The UE may transmit a random access preamble based on the minimum time gap. In some examples, the UE may receive a timing advance (TA) command and may determine a minimum time gap between receipt of the TA command and transmission of a time-adjusted uplink message.
