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.

A method for transmitting uplink signals, which include ACK/NACK signals, control signals other than the ACK/NACK signals, and data signals, is disclosed. The method comprises serially multiplexing the control signals and the data signals; sequentially mapping the multiplexed signals within a specific resource region in accordance with a time-first mapping method, the specific resource region including a plurality of symbols and a plurality of virtual subcarriers; and arranging the ACK/NACK signals at both symbols near symbols to which a reference signal of the plurality of symbols is transmitted. Thus, the uplink signals can be transmitted to improve receiving reliability of signals having high priority.

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.

Various aspects related to ACK/NACK feedback for multi-TRP transmission scenarios are described. A base station, may send, to a UE, information indicating PDCCH monitoring occasions for each of a plurality of TRPs. In one aspect, the base station may send information indicating whether ACK/NACK feedback across the plurality of TRPs is allowed. The base station may send rules to the UE for performing ACK/NACK feedback bundling for providing feedback to the plurality of TRPs. The base station may also send information indicating a DAI definition for interpreting DAIs transmitted by the plurality of TRPs in corresponding PDCCH transmissions indicating whether the DAIs are independent or joint. The base station may receive a joint ACK/NACK feedback from the UE in a PUCCH based on the rules, or may receive multiple ACK/NACK feedback from the UE in a PUCCH for a first TRP independent from a second TRP.

There are provided a communication apparatus and a method. The communication apparatus comprising: a receiver, operative to receive, in a first time period, a plurality of transport blocks (TBs) transmitted by another communication apparatus; and circuitry, operative to generate a plurality of feedback bits respectively for the received TBs, and perform at least one of multiplexing and bundling on at least a part of the feedback bits according to the number of the feedback bits to generate feedback information.

Techniques are provided for retransmission of Physical Uplink Shared Channel (PUCCH) for Ultra Reliable Low Latency Communications (URLLC). A User Equipment (UE) transmits at least one code block of a control channel, the at least one code block including Channel State Information (CSI), wherein each code block is polar encoded by assigning bit indices of the code block to bit channels in a particular order of reliabilities of the bit channels. The UE detects a trigger, and in response, retransmits at least a portion of each code block including retransmitted CSI, wherein the portion is polar encoded by assigning bit indices of the retransmitted CSI to the bit channels in the reverse order of reliabilities of the bit channels as compared to the polar encoding of the CSI.

A method for operating a network node in a millimeter network, mmW network is provided. Operations according to the method include receiving a data packet comprising header information, the header information indicating a source ID, a destination ID, 5 a flow ID and a UE ID; and transmitting, to the preceding network node, an ARQ response message indicating the flow ID and the UE ID and ACK/NACK pertaining to the received data packet. Related devices and methods are also provided.
