Abstract: According to some embodiments, a method is performed by a wireless device. The method comprises obtaining a data channel transmit power for transmitting on a sidelink data channel to a receiving wireless device, obtaining a control channel transmit power for transmitting on a sidelink control channel, and transmitting on the sidelink data channel at the data channel transmit power and on the sidelink control channel at the control channel transmit power. In certain embodiments, the control channel transmit power is based on the data channel transmit power. In other embodiments, the control channel transmit power is determined independently of the data channel transmit power.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine a first sidelink pathloss based at least in part on a first sidelink reference signal from a second UE. The first UE may also determine a second sidelink pathloss based at least in part on a second sidelink reference signal received from a third UE. The first UE may transmit, during a transmission time interval, a first sidelink transmission to the second UE using a first transmit power that is based at least in part on the first sidelink pathloss and a second sidelink transmission to the third UE using a second transmit power that is based at least in part on the second sidelink pathloss. The first sidelink transmission may be transmitted at a first frequency and the second sidelink transmission may be transmitted at a second frequency.

Abstract: Disclosed are techniques to conserve battery of an endpoint device. Example techniques include adjusting the size of messages transmitted by an endpoint device and/or adjusting the transmission rate of an endpoint device. In some configurations, the one or more criteria are used by an endpoint device to determine what data fields to include within a message and/or adjust a transmission rate associated with the transmission of messages by the endpoint device. For instance, the one or more criteria may include the battery level of the device, the time of year, whether the data has already been transmitted by the endpoint device, whether the data has been acknowledged as received by another device, whether the endpoint device has been instructed by another device to reduce the message size and/or adjust the transmission rate, and the like.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communications by a user equipment. An example method generally includes transmitting, on a sidelink channel using a first power level, a reservation of a resource for a sidelink transmission by the UE; determining to use a second power level for the reserved resource for the sidelink transmission; and transmitting on the sidelink channel on the reserved resource using the second power level.

Abstract: Aspects relate to mechanisms for a wireless communication device to generate a superposition transmission of a sidelink signal to be transmitted to at least one receiving wireless communication device and an uplink signal to be transmitted to a base station. The wireless communication device may transmit the superposition transmission on resources allocated by the base station on a common carrier utilized for both sidelink and uplink transmissions. The superposition transmission includes a base layer corresponding to the uplink signal and an enhanced layer corresponding to the sidelink signal. The wireless communication device may further generate and transmit interference assistance information to the receiving wireless communication device for use by the receiving wireless communication device in canceling the base layer from the superposition transmission.

Abstract: Methods, apparatuses, systems, etc., directed to providing a network access by an Access Point (AP) are disclosed herein. In an embodiment, an AP connected to a network via a network link may adapt a first (e.g., a characteristic impacting a first) performance of a first local link for connection to a first WTRU based on a quality of the network link. The AP may adapt a second (e.g., a characteristic impacting a second) performance of a second local link for connection to a second WTRU based on the same quality of the network link, wherein the adaptations of the fist and the second performances may be different.

Abstract: This disclosure provides systems, methods and apparatus for partitioning a physical sidelink shared channel (PSSCH) into multiple shortened PSSCHs (sPSSCHs) within a slot and selecting a transmit power for each sPSSCH. In one aspect, a transmitting user equipment (UE) may select the transmit power for each sPSSCH in accordance with an open loop power control operation. In some examples, the transmitting UE may select a common transmit power for each sPSSCH. Alternatively, the transmitting UE may perform independent power control operations for each sPSSCH and may cap variation in transmit power across sPSSCHs as a result of employing lower and upper bound transmit powers. Additionally, or alternatively, the transmitting UE may provide a default beta offset for the set of receiving UEs via sidelink control information (SCI) part one (SCI-1) and may provide beta offset updates via each SCI part two (SCI-2) transmission in the multiple sPSSCHs.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine that a second UE is to transmit a control channel message retransmission using a first subchannel of a sidelink control channel during a subframe. The first UE may determine that the first UE is to transmit a sidelink transmission using a second subchannel of the sidelink control channel during the subframe, the second subchannel being different from the first subchannel. The first UE may transmit, by the first UE and during the subframe, the control channel message retransmission of the second UE using the first subchannel and the sidelink transmission of the first UE using the second subchannel.

Abstract: Die Erfindung betrifft ein Verfahren zum Betreiben einer Kommunikationseinrichtung (32, 34) eines Kraftfahrzeugs (14), bei dem die Kommunikationseinrichtung (32, 34) zumindest mit wenigstens einem anderen Kraftfahrzeug (16) oder wenigstens einer stationären Gegenstelle (12) kommuniziert, zu welchem Zweck eine drahtlose Kommunikationsverbindung (20, 22, 24) basierend auf linear polarisierten elektromagnetischen Wellen genutzt wird. Für das Nutzen der Kommunikationsverbindung (20, 22, 24) wird ein Sendesignal von der Kommunikationseinrichtung (32, 34) mit einer vorgegebenen Sendeleistung ausgesendet, wobei die Sendeleistung abhängig von einem Empfangen eines Empfangssignals durch die Kommunikationseinrichtung (32, 34), welches in Bezug auf die linear polarisierten elektromagnetischen Wellen zumindest teilweise hierzu orthogonal polarisierte elektromagnetische Wellen nutzt, reduziert wird.
