  • Patent number: 12021769
    Abstract: A flexible NFRP procedure is proposed where the AP can adjust the granularity of the possible answers to a given question. The NFRP trigger frame includes a tone set configuration indication representative of a number of tone groups per RU tone set. The number of possible FEEDBACK_STATUS values consequently also varies, making it possible for the AP to poll the stations for more detailed feedback reports. A station determines which FEEDBACK_STATUS values are available, calculates its FEEDBACK_STATUS value and retrieves the corresponding subset of tone groups on which energy must be sent. Due to the multiples existing tone set configurations, the station also determines the tones forming the subset to be activated, based on the tone set configuration indication. The station can then properly send its feedback report response by activating (emitting energy on) the appropriate tunes and therefore the appropriate tone groups.

  • Patent number: 10623559
    Abstract: Upon detection of a trigger, such as the exceeding of an error threshold or the direction of a user, a diagnostic link system enters a diagnostic information transmission mode. This diagnostic information transmission mode allows for two modems to exchange diagnostic and/or test information that may not otherwise be exchangeable during normal communication. The diagnostic information transmission mode is initiated by transmitting an initiate diagnostic link mode message to a receiving modem accompanied by a cyclic redundancy check (CRC). The receiving modem determines, based on the CRC, if a robust communications channel is present. If a robust communications channel is present, the two modems can initiate exchange of the diagnostic and/or test information. Otherwise, the transmission power of the transmitting modem is increased and the initiate diagnostic link mode message re-transmitted to the receiving modem until the CRC is determined to be correct.

  • Patent number: 10237019
    Abstract: A first communication node (110) receives a stream of code blocks from a second communication node (120) over an acknowledged connection (131.). The first communication node processes the received code blocks in accordance with at least one transport format parameter, TFP, detects errors in received code blocks, and transmits an acknowledgment in respect of groups of code blocks indicating whether at least one error was detected in the group. A first subset of the code blocks of a group are transmitted (e.g., modulated and demodulated) in accordance with a first TFP value, and a remainder of the code blocks are transmitted in accordance with a second TFP value. Because the first and second TFP values are independent, it is possible either to shorten the necessary processing time in the first communication node or, in connection with a predictive acknowledgment mechanism, to make the receiving-side processing of code blocks that do not contribute to the value of the transmitted acknowledgment more robust.

  • Patent number: 9916471
    Abstract: A security mechanism in a database management system enforces processing restrictions stored as metadata to control how different pieces of a multi-nodal application are allowed to access database data to provide data security. The security mechanism preferably checks the data security restrictions for security violations when an execution unit attempts to access the data to insure the nodal conditions are appropriate for access. When the security mechanism determines there is a security violation by a query from an execution unit based on the security restrictions, the security mechanism may send, delay or retry to maintain data security. Nodal conditions herein include time restrictions and relationships with other columns, rows or pieces of information. For example, multiple processing units may execute together, but the security mechanism would prohibit these processing units to access specific pieces of information at the same time through the use of metadata in the database.

  • Patent number: 9830173
    Abstract: An enhanced proxy simulation service can be used to test a complex stateless system, such as a fulfillment network, that depends on upstream and downstream processes in order to operate. The enhanced proxy simulation service can be configured to send an event, such as an order request, so as to appear to be sent from a process upstream of the system; and can be configured to receive a request from the system, such as a request to charge payment information, so as to appear as a downstream process of the system. The proxy simulation service can store events received from the system and apply a set of rules to the stored events to construct a simulated response to the last event received from the system. The simulated response can then be sent to the system being tested.
