The present invention is designed so that, even when the number of component carriers (CC) that can be configured per user terminal is expanded more than in existing systems, UCI including at least HARQ-ACK and CSI can be transmitted with appropriate quality. The user terminal of the present invention separately encodes at least one CC's HARQ-ACK and at least one CC's CSI. The user terminal maps the encoded bit sequence of the HARQ-ACK and the encoded bit sequence of the CSI to radio resources constituting the same PUCCH and transmits the PUCCH.

The method includes that: a first transmission node receives a signal including a Transmission Block (TB) from a second transmission node; the first transmission node obtains states of the P CB sets according to the signal including the TB; the first transmission node determines at least one kind of feedback information in a preset feedback information set according to the states of the P CB sets; and the first transmission node sends the determined feedback information to the second transmission node.

Provided are a device, a system, and a method in which redundancy is changed in accordance with a line state, and thus the optimal redundancy can be set while the current settings are compared to the previous settings. A communication device measures line quality information from a received packet, and generates a redundancy change instruction based on information regarding a line. In a case where the communication device acquires line quality information for the second and subsequent times, the communication device compares the previous redundancy change instruction and the previous line quality information, to the current line quality information, and sets redundancy. Thus, it is possible to suppress the occurrence of congestion and satisfy a target value of the line quality, and to search for a condition which causes the redundancy to be the minimum.

A wireless communication device serving as an NG60 WiGig device includes a PPDU generator that generates an MF control PHY PPDU (physical layer protocol data unit) including a legacy preamble, a legacy header, an NG60 header (a non-legacy header), a data field, and identification information indicating that the non-legacy header is included in the PPDU and a transmitter that transmits the generated MF control PHY PPDU.

Systems, methods, apparatuses, and computer program products for efficient support of conditional scaling for unlicensed cells are provided.

Various embodiments may provide systems and methods for supporting lossy compression of feedback information, such as acknowledgment (ACK) information, negative acknowledgement (NACK) information, etc. Various embodiments may support lossy compression for feedback messages in retransmission systems, such as Hybrid Automatic Repeat Request (HARD) protocols, the Multiple Incremental Redundancy Scheme (MIRS), etc. Various embodiments may support compression of feedback bits using a different compression codebook per symbol or per group of symbols. Various embodiments may support selection of a compression codebook per symbol, or per group of symbols, based at least in part on a probability of successful decoding of each code block in the symbol or group of symbols.

Embodiments of this disclosure relate to a wireless communication method, a device, a storage medium, and a computer program product. The method proposed herein includes: A receiving device generates a feedback frame in response to receiving of an aggregated frame, where the feedback frame includes first indication information and second indication information, the first indication information indicates a window size of a feedback window used to transmit the feedback frame, the window size is determined based on configuration information associated with the feedback window, and the second indication information indicates receiving status information of receiving the aggregated frame by the receiving device; and the receiving device sends the feedback frame to a sending device in the feedback window. This disclosure provides a frame structure of the block acknowledgment-based feedback frame, so that the feedback window used to transmit the feedback frame can be dynamically adjusted at a fine granularity.

An apparatus, method and computer program is provided comprising: determining a plurality of candidate data transmission slots, wherein each candidate data transmission slot has an index and said plurality of candidate data transmission slots are arranged in an order; setting an index of a current candidate data transmission slot of the plurality to be an incremental increase of an index of a preceding candidate data transmission slot of the plurality in the event that a timing gap between a start of said current candidate data transmission slot and a start of a subsequent candidate data transmission slot of the plurality is greater than a threshold; and setting the index of the current candidate data transmission slot to be equal to the index of the preceding candidate data transmission slot of the plurality in the event that the timing gap is not greater than said threshold.

A 4B5B encoder converts an inputted 4-bit data into a pattern of a 5-bit data in which (i) the number of bits of consecutive 0 data values is permitted to be maximum two, and, simultaneously, (ii) maximum one bit of head end two bits is permitted to have a 0 data value and maximum one bit of tail end two bits is permitted to have a 0 data value. A 5N-bit command encoder converts a command into a command pattern in which the number of bits contained in consecutive 0 data values is permitted to be maximum two. The data after the conversion and the command after the conversion are converted into NRZI codes by an NRZI encoder.
