  • Patent number: 11935068
    Abstract: In some embodiments, a method includes in response to an integration tag included in a webpage at a first user interface being executed at a mobile device, receiving a mobile device identifier and a request to retrieve a purchase identifier. The method includes sending a first signal causing a frame to be provided within the webpage at the first user interface. The method includes in response to a first user input, receiving a Hyper Text Transfer Protocol (HTTP) POST request and determining a uniform resource identifier (URI). The method includes retrieving purchase information and sending a HTTP response message including the URI of the second user interface and the purchase information to deeplink to the second user interface and to cause the second user interface to be rendered at the mobile device with the purchase information pre-populated in an input field of a text message.

  • Patent number: 11323986
    Abstract: Described is a method of decoding a physical sidelink control channel (PSCCH). The method comprises: for a PSCCH candidate in a resource grid, processing a received demodulation reference signal (DMRS) in a subframe of the resource grid associated with the PSCCH candidate to determine one or more potential PSCCHs for decoding, each of the one or more potential PSCCHs being identified by resource block (RB) position in the resource grid and a corresponding DMRS cyclic shift (ncs) value. This step is repeated for at least one other DMRS in the subframe to determine one or more potential PSCCHs for the at least one other DMRS. Then, a subset L of PSCCHs is selected from the potential PSCCHs. The selected subset L of PSCCHs together with their corresponding DMRS cyclic shift (ncs) values are made available for use in a decoding process for the received channel signal.

  • Patent number: 11026278
    Abstract: Described is a method of decoding a physical sidelink shared channel (PSSCH) involving physical sidelink control channel (PSCCH) resource grid search space reduction, timing offset (TO) estimation, and reference symbol identification. Resource grid search space reduction may include identifying resource blocks (RBs) having a signal power below a first threshold such that said RBs can be excluded from further processing. Search space reduction may additionally or alternatively include identifying RB pairs where a difference in signal power between the RBs comprising each pair of RBs is above a second threshold and excluding any such said RB pairs from further processing. TO compensation may include circularly correlating TO-compensated received DMRSs and their corresponding local DMRSs to obtain energy or power profiles.

  • Patent number: 10812221
    Abstract: Systems and methods which provide for accurate decoding of a received channel signal when station identifier information is unknown. Embodiments accurately decode a physical downlink control channel (PDCCH), such as to obtain downlink control information (DCI), without knowing radio network temporary identifier (RNTI) information. An unknown station identifier information (USII) of embodiments uses redundancy reduction-based error checking (performing error checking between data decoded from a candidate control channel data block containing redundant data and a portion of that candidate control channel data block containing redundancy reduced data) for implementing decoding when station identifier information is unknown. Embodiments of a USII decoder may use a power detection technique for identifying candidate control channel data blocks used in redundancy reduction-based error checking operation.

  • Patent number: 9491024
    Abstract: A method for performing high speed mode detection of a carrier frequency offset (CFO) includes receiving a Zadoff-Chu signal at a wireless device, and determining a plurality of correlation peaks based on a correlation of the signal with one or more known Zadoff-Chu sequences. The method includes determining a carrier frequency offset (CFO) associated with the signal based on a phases associated with the plurality of correlation peaks and a coarse CFO estimate. The coarse CFO estimate may be determined based on a squared power ratio of particular pairs of the plurality of correlation peaks and the phases may be used to remove ambiguity associated with the coarse CFO estimate.
