The present disclosure relates to a communication scheme and system for combining an IoT technology with a 5G communication system for supporting a higher data transfer rate beyond a 4G system. The present disclosure may be applied to intelligent services (e.g. smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, and security and safety services) on the basis of a 5G communication technology and an IoT-related technology. The present disclosure provides a method and an apparatus for supporting compression and decompression of an Ethernet header.
Distribution of MPEG-2 TS multiplexed multimedia stream with selection of elementary packets of the stream
The invention relates to a distribution method for a multimedia stream multiplexed via a network, the multiplexed multimedia stream comprising multimedia and signalling components, the components being divided into elementary packets of the multiplexed multimedia stream transmitted on at least one transport channel of the network. This method comprises a step of selection of elementary packets of the multiplexed multimedia stream incorporated in transport packets, wherein each of the elementary packets of the signalling components are incorporated in transport packets transmitted on a first of the at least one transport channel, and wherein others transport packets comprising at least one elementary packet and a part only of the multimedia components, are transmitted on a transport channel. This method further comprises a step of transmission of transport packets on each of the transport channels, comprising a step of definition of a first sequence number for each of the transport packets of each of the transport channels and a second sequence number for each of the elementary packets, the first sequence number being incremented for each of the transport packets, independently on each of the transport channels, the second sequence number being incremented for each of the elementary packets.
Demodulation reference signals for retransmission in wireless communication
Provided is a method for wireless communication which includes transmitting codewords according to an initial transmission rank, receiving downlink transmissions indicating at least one of the codewords to be retransmitted, constructing a demodulation reference signal (DM-RS) to be sent with the at least one codeword to be retransmitted, and retransmitting the at least one codeword with the DM-RS according to a retransmission rank. The downlink transmissions may include one or more physical hybrid automatic retransmission request indicator channels and the DM-RS may be constructed based at least in part on information in the downlink transmissions.
Method and apparatus for transporting client signals in an optical transport network
Method and apparatus for transporting client signals in an MN are illustrated. In one embodiment, the method includes: mapping a client signal into a first Optical Channel Data Tributary Unit (ODTU) frame including an ODTU payload area and an ODTU overhead area, such that a plurality of n-bit data units of the client signal are inserted into the ODTU payload area and number information is inserted into the ODTU overhead area; mapping the first ODTU frame into the OPUk frame, such that the plurality of n-bit data units are mapped into an OPUk payload part occupying at least one Tributary Slot (TS) of the OPUk payload area and the number information of the ODTU overhead area is mapped into a first OPUk overhead part of the OPUk frame; forming an Optical Channel Transport Unit-k (OTUk) frame including the OPUk frame for transmission.
Device and method for increasing packet processing rate in a network device
A first set of bits is extracted from a header of a first packet. A second set of bits is extracted from a header of a second packet. The first set of bits and the second set of bits are combined into a combined single data unit representing the first packet and the second packet. The combined single data unit is transferred to a packet processing device. The packet processing device decomposes the single data unit to extract the first set of bits corresponding to the first packet and the second set of bits corresponding to the second packet. A first reduced set of processing operations is performed to process the first packet using the first set of bits corresponding to the first packet. A second reduced set of processing operations is performed to process the second packet using the second set of bits corresponding to the second packet.

Certain embodiments of the invention may include systems, methods, and apparatus for a low rate PHY structure. According to an example embodiment of the invention, a method is provided for generating a low rate PHY structure with low overhead. The method may include generating a preamble comprising one or more training fields; generating a data field; grouping the preamble and the data field into a low rate PHY structure; and converting the low rate PHY structure for wireless transmission over a hardware transmission medium.
Streaming unicast services to multiple user equipment
A content adapter receives a request from a first user equipment to receive a unicast service via a base station and determines that the base station is providing the unicast service to a second user equipment using a service identifier. The content adapter transmits a signal instructing the base station to allocate the service identifier to the first user equipment for receiving the unicast service concurrently with the second user equipment. A base station allocates the service identifier to the first user equipment in response to the first user equipment requesting a unicast service that the base station is already providing to a second user equipment using the service identifier. The base station transmits content for the unicast service for reception by the first and second user equipment based on the service identifier.
Signal transmission/reception method associated with platoon communication in wireless communication system
An embodiment of the present invention relates to a method for transmitting or receiving a signal associated with a platoon communication by a first terminal in wireless communication system, the method comprising the steps of: receiving group resource pool information of a terminal group moving in a platoon formation; selecting a sub-pool, which is to be used by the first terminal, in a group resource pool on the basis of the group resource pool information; and transmitting or receiving a signal to or from one or more terminals within the terminal group through the selected sub-pool.
TECHNOLOGIES FOR REASSEMBLING FRAGMENTED DATAGRAMS
Techniques for reassembling fragmented datagrams are disclosed. Packets may be received and classified. Packets of a fragmented datagram may be stored for later reassembly. In the illustrative embodiment, a datagram is reassembled based on an identified class of service associated with the datagram. Additionally or alternatively, in the illustrative embodiment, a replay window of a replay attack detector may be tuned based on hardware performance of a compute device.
Method to reduce the effect of fixed stream delimiters on emissions and receive filter training
Systems and methods are provided for performing operations comprising: accessing, by a transmitter physical layer (PHY) controller, data for transmission to a receiver PHY controller over a network connection; randomizing a delimiter independently of randomizing the data; selecting a disparity reset value based on the randomized delimiter to generate an initial miming disparity; encoding the randomized data based on the initial running disparity; generating a frame that includes the encoded randomized data and the randomized delimiter; and transmitting the frame from the transmitter PHY controller to the receiver PHY controller.
