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: An apparatus for generating a substantially constant DC reference voltage. The apparatus includes a reference voltage generator configured to generate a substantially constant direct current (DC) reference voltage based on a voltage on a data signal transmission line, wherein the voltage is based on a bandgap reference voltage. In one implementation, the data signal transmission line is a differential signal transmission line and the voltage is a common mode voltage. In another implementation, the data signal transmission line is an I-data signal transmission line and a Q-data signal transmission line, and the voltage is an average or weighted-average of the common mode voltages of the I- and Q-differential signals. In another implementation, the reference voltage is based on a single-ended (e.g., positive- and/or negative)-component or vice-versa of I- and Q-data signals, respectively.

Abstract: Aspects of the present disclosure generally relate to wireless communications. In some aspects, a device may receive a first uplink grant for a first cell that uses a first component carrier, and may receive a second uplink grant for a second cell that uses a second component carrier. The device may determine at least one of: a number of subframes for which uplink data is transmitted on both the first cell and the second cell during a time period, or a resource block allocation associated with the first cell and the second cell. The device may drop at least one of the first uplink grant or the second uplink grant based at least in part on at least one of: a determination that the number of subframes satisfies a threshold number of subframes, or a determination that the resource block allocation satisfies a condition.

Abstract: A positioning signal processing method includes: receiving, wirelessly at an apparatus, a first positioning signal in a first frequency range; receiving, wirelessly at the apparatus, a second positioning signal in a second frequency range; converting the first positioning signal by a first analog-to-digital converter (ADC) of the apparatus to produce a first digital signal at a first sampling rate that is based on a clock signal; and converting the second positioning signal by a second ADC of the apparatus to produce a second digital signal at a second sampling rate that is based on the clock signal and that is different from, and related to, the first sampling rate.

Abstract: A mobile device may be configured to perform concurrent Satellite Positioning System (SPS) operation and wireless communications when uplink signals transmitted by the mobile device interferes with the reception of SPS signals in one or more frequency bands. The mobile device may determine if the SPS receiver has already acquired SPS signals and is in a tracking state. If the SPS receiver is not in a tracking state, an SPS acquisition procedure is initiated before the wireless communication session is initiated. The SPS acquisition procedure is performed until the SPS receiver reaches a tracking state, or until a timeout is reached. Once the SPS receiver is in a tracking state, the wireless communication session may be initiated, during which the SPS receiver is controlled, e.g., to perform signal blanking, measurement exclusion, or disable SPS reception, to mitigate interference with SPS signals.
