The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-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. A method and apparatus according to an embodiment may allow a terminal or a base station to configure parameters for supporting limited buffer rate matching (LBRM) by using higher layer signaling or enable a suitable configuration to be made in a case of not configuring parameters for supporting the LBRM using the higher layer signaling.

A transceiver is designed to share memory and processing power amongst a plurality of transmitter and/or receiver latency paths, in a communications transceiver that carries or supports multiple applications. For example, the transmitter and/or receiver latency paths of the transceiver can share an interleaver/deinterleaver memory. This allocation can be done based on the data rate, latency, BER, impulse noise protection requirements of the application, data or information being transported over each latency path, or in general any parameter associated with the communications system.

A first communication device in a communication systems including the first communication device and the second communication device that performs wireless connection with the first communication device and relays communication with the first communication device, the first communication device includes a receiver configured to receive packets from the second communication device, and a transmitter configured to store reception confirmation packets corresponding to the packets in a buffer, perform transmission at least a portion of the reception confirmation packets stored in the buffer, and discard reception confirmation packets not to be transmitted in the transmission according to a discard ratio.

A receiving station performs first signal detection processing on a received radio signal, performs a retransmission request to a transmitting station in a case in which a code error is detected in a detected radio packet for user data, and enqueues the radio packet in a reception buffer in a case in which no code error is detected. In parallel with the first signal detection processing, the receiving station performs second signal detection processing on the received signal with a longer processing delay than that of the first signal detection processing, and in a case in which no code error is detected in the detected radio packet for user data, the receiving station enqueues the radio packet in the reception buffer. The receiving station outputs, at a predetermined timing, the radio packet for user data with no code error detected, the radio packet being enqueued in the reception buffer.

A method and apparatus for transmitting and receiving a block ACK in a wireless LAN system are disclosed. An operation method for a first communication node comprises the steps of: generating a first data frame including first ADDBA information; transmitting the first data frame to a second communication node; and receiving, from the second communication node, a first RA including second ADDBA information generated by the second communication node in response to the first data frame.

This application provides a data transmission method and an apparatus, and relates to the field of communication technologies. One example data transmission method includes: receiving scheduling information from a first communication apparatus; determining transmission indication information based on the scheduling information; receiving, based on the scheduling information, a first transport block from the first communication apparatus, and determining first hybrid automatic repeat request (HARQ) information of the first transport block; and determining a first HARQ process based on the first HARQ information and the transmission indication information, and allocating the first transport block to the first HARQ process.

Method and apparatus for wireless communication. The method comprises determining respective buffer size tables for at least one logical channel group (LCG) based on at least one reference buffer size (BS) table; generating the BSR for the at least one LCG based on the respective buffer size tables; and transmitting the BSR to a network device, wherein the network device configures a terminal device with the at least one LCG.

The disclosure provides methods and apparatus relating to the transmission of control information in uplink access of wireless networks. One embodiment provides a method performed by a wireless device operable in a wireless communications network. The method comprises: responsive to failure of transmission in a first transmission time interval of a first transport block comprising first control information, transmitting in a second, subsequent transmission time interval a second transport block comprising second control information, wherein the second control information is an updated version of the first control information. Failure of transmission of the first transport block comprises the wireless device determining that a wireless channel over which the first transport block is to be transmitted is busy in the first transmission time interval.

A wireless communication system includes a plurality of wireless communication apparatuses that transmit a wireless frame to a terminal, and a control apparatus, and the wireless communication apparatus transmits information representing the number of retransmissions of the wireless frame to the control apparatus, and the control apparatus acquires the information representing the number of retransmissions of the wireless frame, selects the wireless communication apparatus in accordance with the number of retransmissions, and causes the selected wireless communication apparatus to start transmitting the wireless frame.

A method of wireless communication, by a transmitting device, includes encoding information packets with an outer code to generate a first outer codeword. The first outer codeword includes information packets in addition to parity packets. The method also includes transmitting, to a receiving device, the information packets and the parity packets of the first outer codeword, according to a sequence. A method of wireless communication by a receiving device, includes receiving packets belonging to a first outer codeword, the packets including information packets and parity packets.
