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 communications systems and methods related to improving user equipment (UE) mobility performance are provided. A wireless communication device camps on a first cell operating on a first carrier frequency. The wireless communication device receives, from the first cell, cell selection priority information indicating a priority for each of a plurality of carrier frequencies. The wireless communication device evaluates each of two or more candidate cells over an evaluation time duration associated with each candidate cell, wherein an end time of the evaluation time duration of a candidate cell associated with a lower priority carrier frequency is configured to be after an end time of the evaluation time duration of a candidate cell associated with a higher priority carrier frequency. The first wireless communication device selects a second cell from the two or more candidate cells for camping based at least in part on the evaluation of the second cell.

Abstract: Systems, methods, apparatuses, and media are provided for recovery of information from redundancy version packets in systematic encoding environments when a redundancy version packet containing primarily systematic information may be corrupted. A plurality of redundancy version packets may be received at a user equipment device from a transmission device. Each redundancy version packet of the plurality of redundancy version packets may be based on a same group of information bits. A first redundancy version packet of the plurality of redundancy version packets may contain more bits of the same group of information bits than do the other redundancy version packets of the plurality of redundancy version packets. The same group of information bits may be recovered based on one or more second redundancy version packets of the plurality of redundancy version packets but not based on the first redundancy version packet.

Abstract: Aspects described herein relate to using antenna-switched diversity (ASDIV) in wireless communications. A serving node can be communicated with using a serving radio access technology (RAT) and based on an ASDIV configuration, wherein the ASDIV configuration defines an antenna switching configuration including a state of one or more switches in an ASDIV switch group for switching between one or more antennas for the communicating based on sensing one or more parameters of the communicating. It can be determined whether a target RAT supports operating using a same ASDIV switch group as the serving RAT. A target node can be communicated with using the target RAT and based on the ASDIV configuration where the target RAT operates using the same ASDIV switch group as the serving RAT.

Abstract: Systems and methods are described herein for managing uplink communication activities of a wireless communication device associated with a first subscription and a second subscription. First, a trigger event related to de-sensing of the first subscription by the second subscription is detected. The wireless communication device refrains from requesting uplink (UL) grants for the second subscription from a network for the second subscription in response to detecting the trigger event.

Abstract: Various embodiments include methods for a multi-subscription wireless communication device to obtain caller identification (ID) information for a call coming in on a first subscription while on a call on a second subscription. In various embodiments, when the second subscription is supporting a voice call and a page message for the first subscription is received from a network, the wireless communication device may exclude one or more fields from a page response message from the first subscription to the network, blindly accept a proposed service option sent by the network, and receive caller ID information from the network. In some embodiments, one or more fields from a page response message may include at least one of an additional pilots field and an alternate service option list. Receiving caller ID information from the network may be performed when the first subscription cannot support a proposed service option sent by the network.

Abstract: Various embodiments include methods implemented on a mobile communication device for sharing network information among subscriptions when a first subscription is in a data communication session and a second subscription is in an idle mode. The methods may include determining whether the first subscription and the second subscription share a network operator and are camped on a same base station. If so, the first subscription may receive network information from the base station and store the network information in a shared memory of the mobile communication device that can be accessed by the second subscription. The second subscription may then perform some idle mode operations using the network information stored in the shared memory.

Abstract: Various embodiments provide methods, devices, and non-transitory processor-readable storage media for mitigating local oscillator (LO) spur interference between radio access technologies (RATs) operating on a multi-active communication device. The various embodiments provide methods, devices, and non-transitory processor-readable storage media to determine residual frequency error for a multi-active communication device and generate LO spur handling tables that may enable the multi-active communication device to compensate for the residual frequency error. A multi-active communication device may mitigate LO spurs by applying mitigation techniques to one or more RATs according to the LO spur handling tables. A multi-active communication device may mitigate LO spurs by turning off a LOs for one or more RATs according to the LO spur handling tables.
