  • Publication number: 20230268957
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect that at least a portion of reference signaling expected in a channel is not present in the channel. The UE may modify a Doppler estimation computation associated with the reference signaling based at least in part on detecting that at least the portion of the reference signaling is not present in the channel. Numerous other aspects are described.

  • Publication number: 20220231804
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect whether a reference signal is present in a channel at a time instance at which the reference signal is expected. The UE may selectively gate processing of the reference signal based on detecting whether the reference signal is present in the channel. Numerous other aspects are described.

  • Publication number: 20210250953
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configurations for a plurality of search space sets for a control resource set (CORESET), the plurality of search space sets including one or more of a first type of search space set configured with multiple frequency domain monitoring locations or a second type of search space set configured without multiple frequency domain monitoring locations. The UE may receive a physical downlink control channel communication based at least in part on monitoring the plurality of search space sets according to a determination that the CORESET is associated with search space sets of a same type. Numerous other aspects are described.

  • Publication number: 20190097709
    Abstract: Various aspects of the disclosure relate to ensuring that beamforming feedback is substantially coherent across frequency, time, or some other condition. The disclosure relates in some aspects to generating steering matrix feedback (e.g., at an IEEE 802.11 STA). In some aspects, the generation of the steering matrix feedback uses a singular value decomposition (SVD) algorithm that helps ensure coherence of beamforming feedback. In some aspects, coherence may be achieved by ensuring that the Givens rotations of a matrix are always in the same direction.

  • Patent number: 9083521
    Abstract: A system is provided for transmitting information through a speech codec (in-band) such as found in a wireless communication network. A modulator transforms the data into a spectrally noise-like signal based on the mapping of a shaped pulse to predetermined positions within a modulation frame, and the signal is efficiently encoded by a speech codec. A synchronization sequence provides modulation frame timing at the receiver and is detected based on analysis of a correlation peak pattern. A request/response protocol provides reliable transfer of data using message redundancy, retransmission, and/or robust modulation modes dependent on the communication channel conditions.

  • Patent number: 8364482
    Abstract: A system and method is provided for obtaining a message type identifier embedded in a vocoder packet via a speech codec (in-band) such as found in a wireless communication network. The vocoder packet is received and decoded. The decoded vocoder packet is filtered until a synchronization signal is detected, with the filtering comprising correlating the decoded vocoder packet with a predetermined sequence to generate the synchronization signal. The polarity of the synchronization signal is determined, and the message type identifier is derived based on the polarity of the detected synchronization signal. A first polarity identifies a first message type, and a second polarity identifies a second message type.
