  • Patent number: 11051344
    Abstract: A base station transmits a random access response in response to a random access request (random access preamble) of a user equipment. The random access response includes information about a time when the random access request is transmitted and sequence number information of the random access request (random access preamble). The user equipment checks whether the received random access response is the response of the random access request transmitted by the user equipment, using the information about the time when the random access request is transmitted and the sequence number information included in the received random access response.

  • Patent number: 11018794
    Abstract: A method and apparatus for transmitting or detecting primary synchronization signal. The receiver receives primary synchronization signal from a transmitter, and detects the sequence used in the received primary synchronization signal by using three root indexes. Here, the primary synchronization signal is generated by using a Zadoff-Chu sequence having one of the three root indexes. The three root indexes comprise a first index and a second index, and a sum of the first index and the second index corresponds to the length of the Zadoff-Chu sequence.

  • Publication number: 20200349490
    Abstract: Technologies are provided for context-based instruction delivery to field agents. In some examples, one or more context-sensitive criteria may be extracted from an instruction contained in a message. The message and the criteria may then be transmitted to multiple field agent devices. In response to receiving the message and the criteria, a field agent device may determine whether a legitimate agent is present and the criteria are satisfied. If a legitimate agent is present and the criteria are satisfied, then the agent device may provide the instruction in the message to the legitimate agent. On the other hand, if a legitimate agent is not present, or if the device and/or agent fail the criteria, then the device may ignore the instruction.
