The present disclosure relates to a communication method and system for converging a 5.sup.th-Generation (5G) communication system for supporting higher data rates beyond a 4.sup.th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Further, the present disclosure relates to decoding of a turbo code in a communication system including long term evolution (LTE), and to efficiently implement a method, procedure, and device for receiving and decoding a signal transmitted in a mobile communication system.

In a transceiver, the accuracy of a packet time stamp can be improved by compensating for errors introduced by processing of the packet. A received packet can be received via multiple lanes. A packet time stamp can be measured using a start of frame delimiter (SFD). A last arriving lane can be used to provide a recovered clock signal. A phase offset between the recovered clock signal and the system clock of the transceiver can be used to adjust the time stamp. A position of the SFD within a data block can be used to adjust the time stamp. A position of the data block within a combined group of data blocks can be used to adjust the time stamp. Also, a serializer-deserializer delay associated with the last arriving lane can be used to adjust the time stamp.

The present invention is directed to data communication systems and techniques thereof. More specifically, embodiments of the present invention provide an FEC encoder that processes an interleaved data stream and generates parity symbols that are embedded into FEC blocks. An FEC decoder determines whether to perform error correction based on the parity symbols. When performing error correction, the decoder selects a worst symbol from a segment of symbols, and the worst symbol is corrected. There are other embodiments as well.

A method by a network device for detecting data in a data stream. The method includes receiving the data stream, where the data stream includes a sequence of original characters, generating a sequence of type-mapped characters corresponding to the sequence of original characters, converging each of two or more consecutive occurrences of a first character in the sequence of type-mapped characters into a single occurrence of the first character, inserting beginning/ending of segment indicators in the sequence of type-mapped characters, searching for occurrences of one or more predefined sequences of characters in the sequence of type-mapped characters, and responsive to finding an occurrence of any of the one or more predefined sequences of characters, extracting a sequence of characters in the sequence of original characters corresponding to the predefined sequence of characters found in the sequence of type-mapped characters.

Embodiments of a device and method are disclosed. In an embodiment, a method of wireless communications involves at a receiver, receiving a first packet, subsequently, at the receiver, receiving a second packet, and determining whether the second packet is a repetition of the first packet based on packet acquisition information associated with the first and second packets.

The optical link channel auto-negotiation method may include at least one of the following: configuring a receiving rate, determining whether a receive clock recovered from received data by a physical layer (PHY) module is locked, and in response to determining that the receive clock recovered from the received data by the PHY module is locked, determining that the receiving rate is configured correctly; configuring a first predetermined parameter in response to determining that the receiving rate is configured correctly, determining whether code block data of the PHY module is in a synchronized state, and in response to determining that the code block data of the PHY module is in a synchronized state, determining that the first predetermined parameter is configured correctly.

The present invention relates to a wireless access system supporting machine type communication (MTC), and according to one embodiment of the present invention, a method by which an MTC terminal transmits a hybrid automatic repeat request-acknowledgement (HARQ-ACK) in a wireless access system supporting machine type communication (MTC) can comprise the steps of: monitoring a physical downlink control channel (PDCCH) in a monitoring section having N number of subframes; receiving at least one PDCCH in the N number of subframes; and transmitting HARQ-ACK corresponding to all subframes included in the monitoring section in the Xth subframe after the end subframe of the monitoring section.

The present invention relates to a method for a terminal to receive downlink control information in a wireless communications system and an apparatus therefor. More specifically, the method is characterized by comprising a step for receiving downlink control information (DCI) indicating whether to retransmit an uplink or not, wherein DCI is defined to simultaneously transmit whether to retransmit the uplink for each of the plurality of terminals.

A base station is configured to transmit control information to a terminal device in a radio communication system, wherein an error detection code that is masked by predetermined identification information is attached to the control information, the base station including a generator configured to generate, upon detecting that a length of first information that is to be masked by the predetermined identification information to generate the error detection code does not correspond to a length of the predetermined identification information, second information that corresponds to the length of the predetermined identification information; and an error detection code generator configured to generate, upon detecting that the second information is generated, the error detection code in which the second information is masked by the predetermined identification information.

Embodiments of the present disclosure provide a downlink control information receiving method, a downlink control information sending method, user equipment, and a network side device. The receiving method includes: receiving configuration information of DCI, where the configuration information includes indication information of a location of a target field of user equipment and a function indicated by the target field; receiving the DCI; and obtaining the target field in the DCI based on the configuration information, and obtaining function information carried in the target field.
