Abstract: A method and device for scheduling SR transmissions for a user equipment (UE) associated with an evolved Node B (eNB) of a Long Term Evolution (LTE) network. The method includes determining an SR is to be transmitted to the LTE network, determining an uplink grant behavior of the eNB, when the uplink grant behavior of the eNB indicates that previous uplink grants satisfy a threshold of previous grants occurring in onDurations of the cycle of a C-DRX functionality, selecting one of the at least one SR opportunity that follows a next onDuration relative to when the indication is received and scheduling the SR in the one of the at least one SR opportunity that follows the next onDuration. The method further including determining an uplink grant turnaround time associated with the eNB, and selecting one of the at least one SR opportunity based on the uplink grant turnaround time.

Abstract: Apparatuses, systems, and methods for a wireless device to perform substantially concurrent communications with a next generation network node and a legacy network node. The wireless device may be configured to establish a first wireless link with a first cell according to a RAT, where the first cell operates in a first system bandwidth and establish a second wireless link with a second cell according to a RAT, where the second cell operates in a second system bandwidth. Further, the wireless device may be configured to perform uplink activity for both the first RAT and the second RAT by TDM uplink data for the first RAT and uplink data for the second RAT if uplink activity is scheduled according to both the first RAT and the second RAT.

Abstract: Apparatuses, systems, and methods for a wireless device to perform simultaneous uplink activity for multiple RATs in the same carrier using frequency division multiplexing. The wireless device may establish a first wireless link with a first base station according to a first radio access technology (RAT) and a second wireless link with a second base station according to a second RAT. The first base station may provide a first cell operating in a first system bandwidth and the second base station may provide a second cell operating in a second system bandwidth. The wireless device may determine whether the wireless device has uplink activity scheduled according to both the first RAT and the second RAT. If so, the wireless device may perform uplink activity for both the first RAT and the second RAT in the first system bandwidth using frequency division multiplexing.

Abstract: Described herein are apparatuses, systems and methods for adaptive downlink scheduling and link adaptation. The methods including, at a base station connected to a user equipment (“UE”), determining an initial modulation and coding scheme (“MCS”) for a plurality of subframes to be transmitted to the UE, wherein each MCS relates to a coding rate value for the subframes, determining an MCS pattern for the plurality of subframes based on the initial MCS, wherein an MCS for one of the subframes has a higher coding rate value than the initial MCS, and transmitting the plurality of subframes to the UE according to the MCS pattern.

Abstract: Groupcast communications between devices of a group of devices, e.g. between vehicles in a platoon, may include a device in the group transmitting a groupcast message in a sidelink transmission to the other devices and receiving feedback information in sidelink transmissions from the other devices within the same channel occupancy time (CoT). The feedback information may be transmitted by the other devices in response to the groupcast message including an information request directed to the other devices. The group of devices may include a designated group leader which may manage one or more aspects of the communications of the other devices in the group. The designated group leader may be dynamically switched based at least on the received feedback information. The devices in the group may use beamforming for intra-group and inter-group sidelink communications for efficient spectrum usage.

Abstract: This disclosure relates to techniques for detecting a signal and powering off at least some receiver components if no signal is detected. A wireless device may take one or more measurements of one or more signals. The wireless device may determine, based on the measurements, whether a signal (e.g., a signal of a licensed assisted access cell) is anticipated during an upcoming time period, e.g., a subframe or portion of a subframe. If no signal is anticipated, the wireless device may power off at least some receiver functions.

Abstract: A user equipment (UE) device may perform uplink (UL) data communication using a first radio access technology (RAT) while performing an UL voice call communication using a second RAT. The UL data communication may be supported by a first subscriber identity module (SIM) and the UL packet switched voice call communication may be supported by a second SIM. The UL voice call communication may be a packet switched communication. The communications may be performed by a radio(s) of the UE. The radio(s) may include shared physical layer resources that are shared between the UL data and UL voice communications. The UE may also include a single transmitter that may be shared between the UL data and UL packet voice communications and the UL data communication may use a first portion of the single transmitter's TTI and the UL voice communication may use a second portion of the single transmitter's TTI.
