Referenceless clock and data recovery circuits are described that operate to align the clock/data strobe with each data eye to achieve a low bit error rate. The appropriate frequency and phase to be used is determined by an edge counter based frequency error detector and a phase error detector.

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.

Systems and methods include receiving (51) blocks of data that has been Forward Error Correction (FEC) encoded via Open Forward Error Correction (OFEC) adaptation; decoding (52) the blocks of data; processing (53) checksum data that is included in padding data required in the OFEC adaptation, wherein the padding data is distributed across N rows of payload data; and determining (54) a location of any errors in the payload data based on the processed checksum data. The OFEC adaptation is for mapping the blocks of data into any of a FlexO structure, a ZR structure, and variants thereof, and the location of any errors can be used for error marking.

A programmable switch includes a plurality of ports for communicating with a plurality of network devices. A packet for a distributed system is received via a port and at least one indicator is identified in the received packet. Reliability metadata associated with a network device used for the distributed system is generated using the at least one indicator. The generated reliability metadata is sent to a controller for the distributed system for predicting or determining a reliability of at least one of the network device and a communication link for the network device and the programmable switch.

The present invention refers to methods and network nodes transmitting data in a radio communications system. In particular, the present invention refers to a method including the steps of receiving a portion of a data unit; and starting a processing of the portion of the data unit prior to receiving remaining portions of the data unit, and to a network node configured for executing the method.

Concepts and examples pertaining to improved design for communication systems suffering burst error are described. A processor of a user equipment (UE) receives data over a data channel. The processor also receives an indication that at least a portion of the data channel is subject to interference from one or more interfering signals. The processor either de-weights one or more affected resource elements in the data according to the indication to mitigate impact by the interference or processes the data without considering the indication

In accordance with an example embodiment of the present invention, disclosed is a method and an apparatus thereof for removing jitter introduced by a packet switched network. Each received audio frame comprises a primary portion and a redundancy portion. The redundancy portion comprises a partial redundant copy of a previous frame that is offset by k frames. If a frame n is lost, a frame n+k that comprises the partial redundant copy of the lost frame n, is located in a jitter buffer. Based on the frame n+k, a substitute frame n substituting the lost frame n is created and a substitution indicator of the substitute frame n is set to indicate that the redundancy portion of the substitute fame n should be used in decoding.

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.
