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.

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.

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 transmitting uplink signals comprises multiplexing data and first type control information to output multiplexed signals; mapping the multiplexed signals to a resource region matrix; mapping second type control information to the resource region matrix to overwrite some of the multiplexed signals mapped to specific positions of the resource region matrix corresponding to symbols which are near symbols used for reference signals; and transmitting an output sequence of the resource region matrix to the base station. The second type control information comprises at least one of an ACK/NACK information and a rank indicator (RI), and the first type control information comprises control information other than the rank indicator (RI) and the ACK/NACK information.
