The non-aqueous electrolyte contains the non-aqueous solvent and lithium ions, first cations, and first anions dissolved therein, where the first cation is a metal cation Men+ other than the lithium ion, n representing a chemical valence of the metal cation; the first anion is a tetrafluoroborate anion BF4?; mass concentration of the first cations in the non-aqueous electrolyte is D1 ppm, and mass concentration of the first anions in the non-aqueous electrolyte is D2 ppm, both based on total mass of the non-aqueous electrolyte; and the non-aqueous electrolyte satisfies that D1 is 0.1 to 1250 and that D1/D2 is 0.02 to 2. The non-aqueous electrolyte in this application enables the secondary battery to have good cycling performance, safety performance, and kinetic performance.

Abstract: Example aspects include a method, apparatus, and computer-readable medium for wireless communication at user equipment of a mobile network, comprising receiving, from a base station via a first beam, a pre-grant message requesting the UE to perform a listen-before-talk (LBT) procedure on a second beam. The aspects further include performing, according to the pre-grant message, the LBT procedure on the second beam. Additionally, the aspects include indicating, to the base station, whether the LBT procedure was successful.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate with multiple transmit receive points (TRPs) in a frame based equipment mode. A wireless node (e.g., the UE and/or one or more of the multiple TRPs) may determine, among the UE and the multiple TRPs, an initiating node that acquired a current channel occupancy time. The wireless node may determine a transmission pattern that includes one or more idle periods based at least in part on a fixed frame period structure associated with the initiating node that acquired the current channel occupancy time. The wireless node may refrain from transmitting during the one or more idle periods, wherein the one or more idle periods include at least an idle period associated with the wireless node. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may determine an energy pattern corresponding to a characteristic of the first wireless device. The energy pattern may include at least two sub-periods of different energy levels. The first wireless device may transmit the energy pattern on a channel (e.g., an unlicensed channel) prior to transmitting a first message on the channel to indicate the upcoming message to other devices. A second wireless device may monitor the channel during energy detection intervals and may detect the energy pattern. The second wireless device may determine the characteristic of the first wireless device based on detecting the energy pattern and may modify timing for transmission of a second message on the channel based on determining the characteristic. The first wireless device may transmit the first message on the channel based on transmitting the energy pattern.

Abstract: Certain aspects of the present disclosure provide techniques for channel access. One example method by a wireless node generally includes selecting a mode of operation associated with a configuration for communicating with one or more other wireless nodes, determining a procedure for gaining access to a medium to be used for the communication, wherein the procedure is determined based on the mode of operation, and communicating with the one or more other wireless nodes using the mode of operation after gaining access to the medium based on the procedure.

The non-aqueous electrolyte in this application enables the secondary battery to have good cycling performance, safety performance, and kinetic performance.

Abstract: Wireless communication methods and devices for selective receiver-assisted channel sensing are provided. In some aspects, one or more receivers (e.g., UEs) can be selectively configured to perform receiver-assisted channel sensing (e.g., class A channel sensing) using at least one of trigger signaling and channel sensing configuration by a BS, UE capabilities, or operational mode. For example, a method for wireless communication performed by a user equipment (UE) includes: sensing a channel based on at least one of a receiver-assisted channel sensing trigger, or a UE capability; and transmitting, to a base station (BS) based on the sensing, channel sensing information.

In some aspects, a transmitting (Tx) node may perform a channel measurement in a channel sensing contention slot based at least in part on a measurement time, wherein the measurement time is based at least in part on one or more of a sensing bandwidth or a beam switching time. The Tx may perform, to a receiving (Rx) node, a transmission based at least in part on a value of the channel measurement satisfying a threshold. Numerous other aspects are described.
