  • Patent number: 12232156
    Abstract: Techniques for supplementary sidelink resource configuration in full duplex mode may include a first user equipment (UE) transmitting to a base station an interference report indicating sidelink communication interference. The base station may select a resource pool according to the interference report, where the resource pool includes supplementary sidelink subchannels reserved for receiving sidelink communications and conditionally reserved for transmitting sidelink communications based on the interference report. The base station may transmit, to the first UE or a second UE causing the sidelink communication interference, configuration information indicating the resource pool. Based on the configuration information, the first UE and/or the second UE may perform sidelink communications (with each other or with other UEs) using the supplementary sidelink sub channels.

  • Patent number: 12230982
    Abstract: An apparatus includes a battery pack with N battery bricks, each with a DC output voltage. The output of each brick is connected in series providing a bus voltage. Each brick includes battery power modules (“BPMs”) connected in parallel and each connected to a battery cell. Each BPM charges/discharges the connected battery cell. Each brick has a battery brick controller that provides a control signal to each brick's BPMs. A control signal of a BPM is derived from a BPM error signal that includes a battery cell current of the battery cell of BPM subtracted from a summation of an average current signal, a local droop current and a balancing current. The balancing current is based on a current SOC of the battery cell connected to the BPM and a desired SOC for the battery cell connected to the BPM. A BMS derives the balancing current for the BPMs.

  • Publication number: 20250055612
    Abstract: Methods, systems, and devices for wireless communications are described. The described techniques may allow for a user equipment (UE) to communicate with a network entity using full-duplex communication techniques. For example, the UE may transmit, to the network entity, an indication of respective quantities of transmit chains and receive chains at the UE supports for full-duplex and half-duplex communications. In some cases, the UE may identify one or more fixed subbands within a component carrier (CC) or one or more fixed CCs that are allocated for uplink transmissions, and the UE may identify one or more guard bands between the fixed uplink subbands or uplink CCs and one or more downlink subbands or downlink CCs, respectively. In some examples, the UE may identify a guard interval between half-duplex resources and full-duplex resources to allow time for the UE to switch between the half-duplex resources and the full-duplex resources.

  • Patent number: 12225024
    Abstract: A first dataset that includes an indication of a plurality of network events associated with a time-period is received. For each time sub-period from a plurality of time sub-periods that together span the time-period and to generate a second dataset, a value for each network event from the plurality of network events that occur within that time sub-period is summed. A discrete Fourier transform is performed based on the second dataset to generate a third dataset that includes an indication of a plurality of frequency ranges and a plurality of magnitude values for the plurality of frequency ranges. Each frequency from the plurality of frequencies ranges is associated with a magnitude value from the plurality of magnitude values. A set of candidate frequencies from the plurality of frequencies determined to potentially cause periodic behavior is identified based on the plurality of frequency ranges and the plurality of magnitude values.

  • Patent number: 12207302
    Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive control signaling indicating a configuration for performing channel sensing. The configuration may include one or more parameters corresponding to a processing time associated with the channel sensing. The UE may adjust the processing time associated with the channel sensing based on the one or more parameters and a full duplex capability of the first UE.

  • Patent number: 12206573
    Abstract: This disclosure describes techniques for detecting and monitoring paths in a network. The techniques include causing a source node to generate probe packets to traverse a multi-protocol label switching (MPLS) network, for instance. In some examples, the probe packets include entropy values that correspond to individual equal-cost multi-path (ECMP) paths of the network. The probe packets may be received at an SDN controller from a sink node after traversing the network. Analysis of the probe packets allow path discovery and mapping of the entropy values to ECMP paths. The mapping of discovered paths may be used for optimization of network monitoring activities, including second subsequent probe packets over particular ECMP paths based on the mapped entropy values.
