Abstract: A method is provided for detecting an access zone configuration of a downlink wireless transmission received from a wireless network by a receiver. The method includes steps of activating the receiver, synchronizing the receiver with the wireless network, detecting, by the receiver after the step of synchronizing, a received access zone of the downlink wireless transmission, determining a base symbol of the detected access zone, ascertaining a first gap and a second gap from repetitive information contained within the determined base symbol, concluding, from the ascertained first and second gaps, that the detected access zone is part of a multiple access zone configuration, and registering, after the step of concluding, the receiver with the wireless network.

Abstract: Methods, a wireless device (110) and a radio network node (120) for managing a control block are disclosed. An extended Temporary Flow Identifier, eTFI, is assigned to the wireless device (110) by the radio network node (120). The radio network node (120) constructs the control information. The radio network node (120) performs a bit-wise modulo two addition with a control block and a combination of the eTFI and a pre-determined bit pattern to obtain a modified control block. The radio network node (120) adds channel coding redundancy. The radio network node (120) maps the modified control block onto physical resources. The radio network node (120) sends the modified control block to the wireless device (110). The wireless device (110) decodes the received modified control block removing the channel coding redundancy, performs a bit-wise modulo two addition between the modified control block and a combination of the eTFI and a pre-determined bit pattern to obtain a control block. The wireless device (110) decodes the control block using FIRE-decoding to obtain the control information. The wireless device (110) determines it is the intended recipient of the control information if the TFI information therein matches its assigned TFI. Corresponding computer programs and carriers therefor are also disclosed.

Abstract: A system for managing holdover. The system may include a local oscillator device. The system may include a phase locked loop (PLL) device coupled to the local oscillator device and a reference clock source. The PLL device may obtain a reference clock signal from the reference clock source to produce an extracted clock signal. The system may include a drift monitoring device coupled to the local oscillator device and the PLL device. The drift monitoring device may determine an amount of oscillator drift within the local oscillator device using the extracted clock signal and an oscillator signal from the local oscillator device. The system may include a drift compensation device coupled to the drift monitoring device and the PLL device. The drift compensation device may transmit a drift compensation signal to the PLL device based on the amount of oscillator drift.

Abstract: Data is sent from a memory buffer device to a host device over a link. An error in the data is determined. A read response cancellation signal is sent to the host device to indicate the error to the host device, where the read response cancellation signal is to be sent subsequent to the data being sent from the memory buffer device to the host device.

Abstract: Systems and methods for indicating internal transmitter errors in a Controller Area Network (CAN). In some embodiments, a method may include initiating, by a device coupled to a CAN, transmission of a message via the CAN; detecting an error by the device during the transmission; and continuing, by the device after having detected the error, the transmission of the message without causing or indicating a bus error condition. In other embodiments, a CAN node may include message processing circuitry configured to receive a frame from a transmitter, the frame comprising a cyclic redundancy check (CRC) field, the message processing circuitry further configured to identify an internal error of the transmitter based upon the CRC field.

Abstract: Disclosed are various embodiments that relate identifying a source of corruption in a network made up of multiple network nodes. A network node is configured to provide corruption source identification while handling packets according to a cut-through scheme. According to some embodiments, a network node may perform a running error detection operation on a cut-through packet and then insert a debug indicator into the cut through packet. In other embodiments, the network node may process some packets according to a cut-through scheme while process other packets according to a store-and-forward scheme to detect packet corruption in a network.

Abstract: Data communications are effected over one or more network branches to ensure appropriate receipt of data at different devices on the network. In accordance with an example embodiment, time-based communications are effected for a plurality of different network devices, at least two of which are connected to a common wired network link, with each network device being assigned to communicate during different time slots within a communication cycle. Each communication received on the common wired network link is assessed as being error-indicative or not error-indicative. In response to a received communication on the common wired network link being assessed as being error-indicative, the common wired network link is operated to corrupt data received on the branch, such as by driving the branch during a time slot in which the error-indicative communication is received, therein ensuring that other network devices disregard the data received during that time slot.
