Abstract: An electronic device receives an indication of a number of physical resource blocks and subcarrier spacing of at least a portion of a transmission channel and determines a dynamic transmission bandwidth, or receives an indication of a modulation coding scheme of the transmission channel and determines a modulation order. The electronic device transmits, using a transmitter, a signal over at least the portion of the transmission channel based on the dynamic transmission bandwidth being less than or equal to a threshold bandwidth, or the modulation order not corresponding to an additional power backoff, using a first power based on a maximum output power capacity of the electronic device and a maximum power reduction. Otherwise, the electronic device transmits the signal over at least the portion of the transmission channel at a second power based on the maximum output power capacity, the maximum power reduction and the additional power backoff.

Abstract: This disclosure relates to techniques for performing radio link monitoring and cell searching when moving at high speeds. A movement speed of a wireless device may be determined. When performing a cell search, the manner of the cell search may depend on the movement speed of the wireless device, potentially including cells that are associated with high movement speed being more highly prioritized when the wireless device is determined to be at a higher movement speed than when the wireless device is determined to be at a lower movement speed.

Abstract: Systems and methods for reducing collisions of transmission data for a first subscriber (e.g., a voice subscriber) with transmission data for a second subscriber (e.g., a data subscriber) at a dual sim dual active (DSDA) user equipment (UE) are described herein. A DSDA UE may be configured to implement a modified skipUplinkTxDynamic feature that avoids collisions by buffering transmission data of the data subscriber and sending a (later) scheduling request (SR) for a grant for that data. A DSDA UE may regulate data subscriber transmissions to avoid a transmission duration for the voice subscriber. A DSDA UE may reduce certain transmissions for a voice subscriber (subject to a block error rate (BLER) threshold for the voice subscriber) to lower the probability of collision. A DSDA UE may operate a data subscriber and a voice subscriber in the same cell to avoid collisions due to RF tuning and/or relative slot overlap.

Abstract: This disclosure relates to techniques for multi-RAT and DSDA capable wireless devices to handle frame blanking in a wireless communication system. A wireless device may establish wireless links according to a first radio access technology and a second radio access technology. The wireless device may determine to perform transmit and receive blanking for one or more antennas of the wireless device for the first radio access technology to perform sounding reference signal transmissions for the second radio access technology based at least in part on a band combination for the wireless links. The wireless device may determine a modification to channel state feedback reporting for the first radio access technology based at least in part on the transmit and receive blanking. The wireless device may perform channel state feedback reporting using the determined modification.

Abstract: An electronic device may include wireless circuitry with first and second receivers. Each receiver may include circuitry for receiving radio-frequency signals using a first radio access technology (RAT) and using second or additional RATs. The wireless circuitry may perform system selection in which the receivers attempt to acquire a signal transmitted by a base station using different RATs. The first receiver and the second receiver may concurrently perform system selection in which the first receiver performs a band scan over the first RAT while the second receiver concurrently performs a band scan over a second or additional RAT. Additional band scans may be performed as needed until a signal is acquired. Once a signal is acquired, the wireless circuitry may establish cellular communications with the wireless base station based on the acquired signal. This may minimize the amount of time required to begin cellular telephone communications in many situations.

Abstract: A method for determining whether to allow performance of an inter-radio access technology (IRAT) transition is provided. The method can include a wireless communication device determining a realized quality of service (QoS) for packet switched data traffic on a first radio access technology (RAT); determining whether the realized QoS satisfies a threshold QoS; suspending IRAT transition to a second RAT in an instance in which it is determined that the realized QoS satisfies the threshold QoS; and allowing IRAT transition to the second RAT in an instance in which it is determined that the realized QoS does not satisfy the threshold QoS.
