  • Publication number: 20220360347
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless device may obtain, in a frequency range, device-specific data for use in determining at least one of a frequency or a power of a spurious signal. The wireless device may generate, based at least in part on the device-specific data, information that indicates the at least one of the frequency or the power of the spurious signal. Numerous other aspects are described.

  • Publication number: 20220361101
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, one or more downlink grants scheduling one or more corresponding downlink transmissions from the base station to the UE. In some examples, the UE may enter a state of sleep prior to receiving the one or more downlink transmissions. In such examples, the UE may wake up from the state of sleep at a first time that is at least a threshold period of time before a second time corresponding to a beginning of the one or more downlink transmissions. After waking up from the state of sleep, the UE may activate a notch filter and use the activated notch filter to filter a spur generated at the UE. The UE may receive the one or more downlink transmissions with improved reliability based on activating the notch filter.

  • Patent number: 11318649
    Abstract: One aspect relates to an injection molding system for the injection molding of amorphous metals, an injection molding unit for the injection molding of amorphous metals and an injection molding process for amorphous metals. The injection molding system includes a channel for feeding a molten metal and a slider unit including a slider and a pressure system. The slider is located between the channel and at least one injection molding cavity and is movable between a rest position and an injection position. In the rest position, the slider blocks the access of the molten metal to the injection molding cavity and in the injection position it allows the molten metal to access the injection molding cavity. The pressure system holds the slider in the rest position and allows the slider to move to the injection position when a minimum pressure is exceeded.

  • Publication number: 20210211981
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify conditions associated with one or more physical channels, for example, a set of resources with which the UE may be configured to communicate with a base station. The UE may determine whether to enable a reduced power mode based on the conditions satisfying certain criteria, for example, the set of resources corresponding allocated for particular transmissions. The UE may identify that the conditions satisfy corresponding criteria, and the UE may determine to enable the reduced power mode. The UE may accordingly modify operations one or more components of a receive chain of the UE. The UE may determine to disable the reduced power mode based on the conditions failing to satisfy the criteria, and the UE may modify operations of the one or more components of the receive chain accordingly.

  • Patent number: 9960938
    Abstract: Methods, systems, and devices are described for generating a hybrid waveform for data transmission between a transmitting device and a receiving device. The transmitting device may employ an OFDM processing technique to periodically transmit known first pilot symbols mapped from a signal constellation where each signal has equal energy during a first time period and a cyclic prefix based single-carrier (CP-SC) processing technique to transmit data packets and second known pilot symbols during a second time period. Channel estimation is based on first pilot symbols, which are inserted into all subcarriers of OFDM symbol blocks within a specific period. Channel estimation tracking is based on the second pilot symbols interleaved within data packets. The receiving device may be configured to estimate CSI based in part on first pilot symbols and to track the channel estimation based in part on the second pilot symbols in order to provide reliable data detection.

  • Patent number: 9473328
    Abstract: A coax network unit (CNU) is coupled to a coax line terminal (CLT). In first and second modes of operation, the CNU transmits data during an upstream window and receives data during a downstream window. In the first mode of operation, a duration of data transmission for the upstream window or a duration of data reception for the downstream window is reduced by a specified amount with respect to the second mode. A sounding signal is transmitted in the first mode in a probing slot that has a duration corresponding to the specified amount.
