A method and apparatus for suppressing vocoder noise are provided. In the method, first information and second information are received from a channel decoder, the first information indicating whether a decoded data frame has an error and the second information being a channel quality metric, error concealment voice decoding is performed on the decoded data frame if the first information indicates that no channel decoding error has been generated and the second information is smaller than a predetermined first threshold, and normal voice decoding is performed on the decoded data frame if the first information indicates that no channel decoding error has been generated and the second information is equal to or larger than the first threshold.

Some demonstrative embodiments include apparatuses, devices, systems and methods of communicating an Enhanced Directional Multi-Gigabit (DMG) (EDMG) Orthogonal Frequency-Division Multiplexing (OFDM) Physical layer (PHY) Protocol Data Unit (PPDU). For example, an EDMG station (STA) may be configured to generate an EDMG OFDM PPDU including at least a non-EDMG header (L-Header), an EDMG header, and a data field, the EDMG header including a spoofing error length indicator field configured to indicate whether or not a spoofing error of the EDMG OFDM PPDU is less than one OFDM symbol duration; and to transmit the EDMG OFDM PPDU over a channel bandwidth in a frequency band above 45 Gigahertz (GHz).

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine to decode or refrain from decoding a transport block (TB) transmitted from a base station based on a decodability condition. The decodability condition may include whether an effective UE throughput for decoding the TB is greater than a predetermined decoding throughput threshold or not. If the effective UE throughput is greater than the predetermined decoding throughput threshold, the UE may refrain from decoding the TB. In some cases, the TB may be a subsequent transmission from the base station based on an initial transmission not being correctly decoded, and the UE may refrain from decoding the subsequent transmission.

A Bluetooth receiver is provided. The Bluetooth receiver comprises interface circuitry configured to receive a receive packet. Further, the Bluetooth receiver comprises physical layer processing circuitry configured to demodulate the receive packet into a bit stream representing a sequence of data symbols. Further, the physical layer configured to determine a number of bits in the bit stream having a highest likelihood of being erroneous as weak-bits and determine locations of the identified weak-bits in the bit stream. The Bluetooth receiver further comprises medium access control layer processing circuitry configured to receive the bit stream and information about the determined locations of the identified weak-bits from the physical layer processing circuitry. Further, the medium access control layer is configured to flip one of the weak-bits and a sequential bit in the bit stream in order to generate a modified bit stream, run a respective cyclic redundancy check on the bit stream and the modified bit stream and compare results of the cyclic redundancy checks on the bit stream and on the modified bit stream.

Embodiments of this application provide a communication method, a communications device, and a storage medium, to process an invalid block in a data stream. In embodiments of this application, N first block streams are obtained, where N is a positive integer. When there is an invalid block in the N first block streams, the invalid block in the N first block streams is converted into a target block, to obtain a to-be-sent block stream. Then, the to-be-sent block stream is sent. Because the invalid block in the block stream is checked and converted into the target block, an error that occurs in service data at a receive end and that is caused by the invalid block can be reduced.

A method of communicating between nodes in a network where a node receives a sequence of symbols that will form a packet on a first communications channel and has a planned packet that it would send on a second communications channel. A destination is encoded into an arbitration portion of a header sequence of the packet, the header sequence comprising a sequence of symbols. The transmission on the second communications channel is as per the planned packet, for as long as the symbols of the planned packet match the symbols being received on the first channel. An arbitration decision is made when the symbols do not match, with the node either continuing to send the rest of the planned packet, or the rest of the packet being received on the first communications channel.

Systems and methods include receiving blocks of data that has been Forward Error Correction (FEC) encoded via Open Forward Error Correction (OFEC) adaptation; decoding the blocks of data; processing Cyclic Redundancy Check (CRC) 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 a location of any errors in the payload data based on the processed CRC data. The OFEC adaptation is for mapping the blocks of data into any of a FlexO-x frame structure, a ZR frame structure, and variants thereof, and the location of any errors can be used for error marking.

A network interface device, said network interface device has a data transmission path configured to receive data for transmission. The data for transmission is to be sent over a network by the network interface device. A monitor is configured to monitor the data transmission path to determine if an underrun condition is associated with the data transmission path. If so, an indication is included in the transmitted data packet.
