    Abstract: A base station selects, from among a plurality of code sequences orthogonal to one another, one code sequence by which an uplink signal including a demodulation reference signal repeated in a plurality of subframes is multiplied and transmits, to a terminal for which transmission of the repeated uplink signal is configured, information indicating the selected code sequence by using a field for indicating a cyclic shift and an orthogonal sequence used for the demodulation reference signal. A terminal receives information indicating one of a plurality of code sequences orthogonal to one another using a field for indicating a cyclic shift and an orthogonal sequence used for a demodulation reference signal and multiplies an uplink signal including the demodulation reference signal repeated in a plurality of subframes by the code sequence indicated by the information.

    Abstract: The present disclosure provides a communication apparatus including circuitry, which, in operation, generates a transmission signal that includes a signal field and a data field, the signal field indicating one or more user-specific allocations in the data field. An aggregate medium access control protocol data unit (A-MPDU) transmitted in each of the one or more user-specific allocations is segmented into one or more code blocks. The communication apparatus includes a transmitter, which, in operation, transmits the generated transmission signal and a receiver, which, in operation, receives a null data packet (NDP) or a medium access control (MAC) frame carrying hybrid automatic repeat request (HARQ) feedback information for the one or more code blocks.

    Abstract: The communication apparatus comprises a receiver which, in operation, receives a PHY layer Data Unit that includes a duration field; Physical (PHY) layer circuitry which, in operation, issues a PHY-CCA (clear channel assessment) primitive parameter indicating bandwidth information on a busy or idle state for each subchannel within an operating bandwidth; and Media Access Control (MAC) circuitry which, in operation, updates a Network Allocation Vector (NAV) value based on the duration information and, in operation, determines busy/idle state of at least one subchannel, wherein the MAC circuitry, in operation, controls transmission of the HE TB PHY layer Data Unit based on the updated NAV value and the busy/idle state of the at least one subchannel, and controls the PHY circuitry to have the HE TB PHY layer Data Unit transmitted when the at least one subchannel is considered idle, regardless of whether the primary subchannel is busy or not.
