  • Patent number: 11146360
    Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for improved data transmissions using puncturing and binary sequences. A receiving device receives a sequenced data input that includes a set of individual values and performs a puncturing of the sequenced data input, yielding a punctured sequenced data input. The receiving device calculates correlation values for the punctured sequence data input and a set of predetermined data outputs. The receiving device determines whether any of the resulting correlation values exceeds a threshold correlation value. In response to determining that the correlation value calculated based on one of the predetermined data outputs exceeds the threshold correlation value, the receiving device determines that the sequenced data input corresponds to the predetermined data output.

  • Patent number: 11140669
    Abstract: The present invention is designed so that the transmission of A/Ns can be controlled properly when the reference value for the timing for transmitting signals is controlled in radio base stations and/or user terminals. A user terminal, according to the present invention, has a receiving section that receives a downlink (DL) shared channel, and a control section that controls transmission of retransmission control information in response to the DL shared channel. The control section controls the transmission of the retransmission control information based on a reference value that is configured for timing for transmitting the retransmission control information.

  • Patent number: 11129002
    Abstract: A method for supporting a first mobile station to predict the channel quality for a planned decentralized wireless communication to a communication partner station which includes sending to the first mobile station from a second mobile station a report about the channel quality measured at the second mobile station. This report includes at least one information entry about the channel quality measured by the second mobile station at a position for a communication to or from a third mobile station indicated in the report. The first mobile station benefits from the historical channel quality measurements of the second transportation vehicle. The accuracy of the channel quality prediction is thus increased.

  • Patent number: 11089546
    Abstract: Devices and methods for prolonging battery life of an inventory tracking tag. The tag determines its location and reports to remote server over a cellular data connection using the cellular communication subsystem. The remote server assesses whether the tag is within range of a short-range communication network, such as a WiFi network, and sends an instruction message over the cellular data connection to instruct the tag to use the first short-range communication network. The instruction message may include credentials for connecting to the network. The tag disables the cellular communication subsystem, enables the short-range communication subsystem, and requests a connection to the first short-range communication network for the purpose of sending future location reports to the remote server.

  • Patent number: 11076427
    Abstract: Techniques are described for handling collisions between uplink transmissions and downlink transmissions over a wireless spectrum. Some of the techniques allow a UE to perform a collision management procedure after identifying a transmission collision (e.g., a collision between a downlink transmission with repetition and an uplink transmission, or a collision between a downlink transmission with repetition and a guard frame for an uplink transmission). The collision management procedure allows the UE to refrain from transmitting at least part of an uplink transmission, refrain from decoding at least part of a downlink transmission, or a combination thereof. Other techniques allow a base station to mitigate transmission collisions by scheduling downlink transmissions based on received, inferred, or determined parameters of uplink transmissions.
