Abstract: An encoder outputs a first bit sequence having N bits. A mapper generates a first complex signal s1 and a second complex signal s2 with use of bit sequence having X+Y bits included in an input second bit sequence, where X indicates the number of bits used to generate the first complex signal s1, and Y indicates the number of bits used to generate the second complex signal s2. A bit length adjuster is provided after the encoder, and performs bit length adjustment on the first bit sequence such that the second bit sequence has a bit length that is a multiple of X+Y, and outputs the first bit sequence after the bit length adjustment as the second bit sequence. As a result, a problem between a codeword length of a block code and the number of bits necessary to perform mapping by a set of modulation schemes is solved.

Abstract: A method includes allocating, by a controller to each of a plurality of wireless nodes, at least one initial slot for transmission of new data in a first frame and at least one retransmission slot for retransmission of data in one or more subsequent frames, including allocating to a second wireless node at least a first retransmission slot for data retransmission in one or more frames subsequent to a first frame; determining that there is a failed data transmission from a first wireless node during a first frame; determining that the second wireless node does not need the at least the first retransmission slot; and transmitting a retransmission slot allocation message including information indicating that the at least the first retransmission slot has been allocated to the first wireless node for at least one frame subsequent to the first frame.

Abstract: Example embodiments of the present disclosure relate to repetition solution for transmission. In such solution, a first device determines information associated with a movement direction of a second device serving the first device relative to the first device. Then, the first device performs a transmission of the information to the second device. With this solution, repetition number is able to be selected/determined at both the first device and the second device based on the information such as change trend of pathloss/RSRP, the change trend of RSRP of a signal received from the second device, the change trend of a distance between the first device and the second device, the change trend of an elevation angle between the first device and the second device, the change trend of a SINR of a signal received from the second device, the change trend of RSRQ of a signal received from the second device, the change trend of a Doppler shift of a signal received from the second device, or elevation angle of the second device, thereby optimizing the resource usage of the network and reducing the transmission time as well as the power consumption for the first device or reducing the failure of the transmission.

Abstract: A method and apparatus according to the present invention addresses and/or prevents lost protocol synchronization in HARQ systems caused by ACK/NACK errors. One embodiment detects lost synchronization errors for NDI-based retransmission protocols and restores synchronization by sending an explicit RESET message. In response to the RESET message, the transmitter aborts the transmission of a current PDU and transmits a new PDU and corresponding NDI. Another embodiment prevents protocol synchronization errors by sending scheduling grants on a packet by packet basis. The receiver sends a subsequent explicit scheduling grant to the transmitter based on an error evaluation of a received PDU. The transmitter will not send the next PDU unless it receives the subsequent explicit scheduling grant.

Abstract: A transmitter (12) obtains data packets at a higher layer (16A) of a protocol stack (16), and duplicates each data packet at the higher layer (16A) to obtain duplicates of each data packet. The duplicates are transmitted on different respective channels from the higher layer (16A) to a lower layer (16B) of the protocol stack (16). The transmitter (12) generates different transport blocks to include data from the different respective channels, such that the duplicates of each data packet are conveyed by different transport blocks. For each transport block, the transmitter (12) transmits or does not transmit at least a part of the transport block within at least a part of a different respective transmission opportunity on a link (26) to a receiver (14) using unlicensed frequency spectrum (28), depending on whether or not a channel sensing procedure indicates the unlicensed frequency spectrum (28) is clear during that at least part of the transmission opportunity.
