Abstract: Aspects of the present disclosure describe indicating per-packet quality of service (QoS) in communications by a wireless communications device. A packet from an application generated for a first radio access technology (RAT) can be obtained, where the packet includes a first QoS value associated with the first RAT, and/or the first QoS value can be mapped to a second QoS value associated with the second RAT. In another example, the QoS value can be indicated in the packet along with a reflective indicator indicating to use the QoS value in transmitting a response to the packet.

A user equipment (UE) may identify a set of one or more sidelink resources, and the UE may identify wake-up signal occasions associated with the resources. The UE may monitor for wake-up signals during the wake-up signal occasions, and the UE may further monitor the associated set of one or more resources based on receiving a wake-up signal. In some examples, respective sets of one or more sidelink resources may be associated with a number of multiple-input multiple-output layers used for sidelink communications, or may indicate respective bandwidth parts used for monitoring sidelink transmissions.

Abstract: Methods, systems, and devices for sidelink wireless communications are described in which a user equipment (UE) engaged in sidelink communications may provide for radio link maintenance of the sidelink connection by initiating a maintenance procedure, such as a measurement procedure, when one or more conditions are detected. The one or more conditions may include a threshold time being exceeded since a data transmission via the sidelink connection, or a threshold time being exceeded since a successful reception of a sidelink transmission from another UE. An access stratum layer at the initiating UE may format a data packet in the absence of higher layer data to be transmitted via the sidelink connection to initiate the maintenance procedure.

Abstract: Aspects relate to managing a device-to-device communication link via radio resource control (RRC) layer signaling. In an example operation, a first wireless communication device establishes a unicast link with a second wireless communication device over a device-to-device communication interface and determines that the unicast link is to be reconfigured with at least one updated parameter. The first wireless communication device then sends a link reconfiguration request to the second wireless communication device via a first RRC message over the communication interface. The first RRC message includes the at least one updated parameter. The first wireless communication device receives a link reconfiguration response from the second wireless communication device via a second RRC message over the communication interface based on the link reconfiguration request and determines whether to reconfigure the unicast link using the at least one updated parameter based on the received link reconfiguration response.

Abstract: Certain aspects of the present disclosure are generally directed to techniques for selecting a configuration for communication using vehicle to everything (V2X) type communication protocol. Certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes determining one or more parameters corresponding to quality of service (QoS) information for communication of data using a V2X communication protocol, reporting the one or more parameters by transmitting a first message, receiving a second message indicating configuration information corresponding to the communication of the data using the V2X communication protocol, and communication the data based on the configuration information.

Abstract: Methods, systems, and devices for wireless communications are described in which two or more UEs of a wireless communications system may establish a sidelink connection. A first UE that is initiating sidelink communications may evaluate whether the sidelink connection can support a quality of service (QoS) for a data flow prior to admitting the data flow. The first UE may evaluate a link quality with one or more other UEs that are to use the data flow on the sidelink connection, evaluate system congestion of time/frequency resources that are available for the sidelink connection, or any combinations thereof, and admit the data flow based on the evaluation. A link quality of the sidelink connection may be determined based on a type of communication associated with the data flow, such as unicast communications with one other UE, multicast communications with multiple other UEs, or broadcast transmissions to multiple UEs.

Abstract: A circuit for a multiplexer includes a pair of NAND gates with outputs coupled to an OAI gate constructed from a complementary circuit formed from solid state devices. A current flow controller formed from solid state devices is coupled to one of the NAND gates.

Embodiments reduce power consumption in integrated circuits by generating full and reduced swing signals at an output of a driver module in response to a control signal during and deactivating one or more elements to conserve power after an input signal remains unchanged for a period of time. Another embodiment reduces power consumption in a circuit, the embodiment comprising a swing module coupled with a swing selector and an output controller. The swing module may generate full or low swing signals depending on the state of the swing selector. The output controller may increase the output impedance of the swing module after an input signal to the swing module remains unchanged for a quantity of time. Various apparatus embodiments include portable computing devices and cellular telephones.

Abstract: A method of preventing current leakage in logic circuits within level sensitive scan design (LSSD) latch circuits in an application specific integrated circuit (ASIC). When the ASIC is in a manufacturing test mode, a gating signal at an input terminal of a power gating circuit is set to exceed a threshold voltage of transistors within the power gating circuit. The gating signal thus causes the power gating circuit to enable electrical current to reach the LSSD latch circuits. When the ASIC is in a normal functional mode, the gating signal is set below the threshold voltage. The gating signal thus causes the power gating circuit to prevent electrical current from reaching particular logic circuits (e.g., scan logic) within the LSSD latch circuits, thereby conserving power within the ASIC by preventing current leakage and heat generation in the LSSD latch circuit.

Abstract: Methods and apparatuses to decrease power consumption and reduce leakage current of integrated circuits are disclosed. New leakage power saving techniques for various types of integrated circuits, including cache memory circuits, are discussed. Embodiments comprise methods and apparatuses to reduce power consumption in integrated circuits by using virtual voltage rails, or virtual power rails, to supply power to integrated circuit loads. The methods and apparatuses generally involve using one or two virtual power control devices to “head” and “foot”, or sandwich, the integrated circuit loads from firm power supply rails. In these method embodiments, one or more elements sense the voltage of the virtual power rails, or nodes, and make adjustments to control the voltage at certain “virtual” voltage potentials. While controlling the voltage in this manner, the virtual power control devices may serve to restrict unnecessary current flow through the integrated circuit loads.

Abstract: An eight-transistor tri-state driver. The tri-state driver implements multiple cascade structures where each cascade structure may refer to a pair of complementary transistors serially connected. Each cascade structure may include a p-conductivity type transistor serially connected to a n-conductivity type transistor. By implementing cascade structures in a tri-state driver, there is a lower peak current consumption, a reduced slew rate as well as a reduction in the amount of layout area used in comparison to the classic tri-state drivers.

Abstract: A device is disclosed for providing compensation current continuously to compensate for leakage current at the node of an electrical circuit, such as a chip. The device includes a dummy storage cell, a single staged current mirror circuit and a non reconfigurable keeper circuit. The keeper can be used to compensate for a wide range of leakage corners where the internal storage is located. The adaptive keeper circuit not only increases the robustness of the storage node against leakage caused by process variation but also improves the overall performance of the static storage device connected to the node.
