Embodiments of the present disclosure provide a method for transmitting uplink control information. The method includes: a User Equipment (UE) receives Uplink Control Information UCI configuration information, wherein the UCI configuration information includes information for determining a periodicity, an offset and a Physical Uplink Control Channel PUCCH for Periodic-Channel State Information P-CSI to be report in one subframe and configuration information for transmission of Hybrid Automatic Retransmission reQuest-Acknowledgement HARQ-ACK; processes one or more kinds of UCI in the subframe, and transmits the on resources using a PUCCH format. According to the method of the present disclosure, the transmit power for transmitting the UCI on the channel using the PUCCH format is optimized. During the transmission of the P-CSI, the PUCCH resource most preferable for the transmission of the P-CSI is determined. The uplink resource utilization ratio is increased.

Intelligent hybrid automatic repeat request (HARQ) feedback can better support link adaption. Thus, in addition to the traditional HARQ feedback, which is to relay acknowledgement (ACK) and negative acknowledgement (NAK) data based on a decoding result, a new state for the HARQ feedback can be represented as “ACK+”. Consequently, ACK+ can be used to indicate to the network that a modulation and coding scheme (MCS) of a current data packet is too conservative, and the user equipment (UE) is capable of supporting a more aggressive MCS.

A method implemented in a transmitter/transceiver, the method including mapping any number of elements of an uplink control information (UCI) signal sequence (SS) to available subcarriers for transmitting an OFDM symbol for carrying information associated with a Physical Uplink Shared Channel (PUSCH), each of the subcarriers having at least two layers, precoding the mapped elements as a function of the layer of the subcarrier to which the elements are mapped, wherein a first precoding applied to a mapped element of a first layer of a subcarrier is different than a second precoding applied to a mapped element of a second layer of the same subcarrier, feeding the mapped elements of the UCI SS to an IDFT unit and transforming the mapped elements into an IDFT transformed signal that includes the mapped elements of the UCI SS carried by a plurality of resources for transmission.

The present specification discloses a method for receiving, by a terminal, a machine type communication (MTC) physical downlink control channel (MPDCCH) from a base station in a wireless communication system, the method comprising: receiving, from a base station, configuration information related to reception of a demodulation reference signal (DMRS) to which one of a plurality of candidate precoders applied to a cell specific reference signal (CRS) is applied; receiving, from the base station, the DMRS and control information through the MPDCCH on the basis of the configuration information; performing channel estimation on the MPDCCH on the basis of at least one of the DMRS or the CRS; and demodulating the control information on the basis of the channel estimation, wherein when a subframe which is not available for the CRS exists in an MPDCCH repetition, the channel estimation is performed using only the DMRS.

A method and an apparatus for transmitting an EHT PPDU in a WLAN system are proposed. Specifically, a transmitter generates an EHT PPDU and transmits, on the basis of an RF, the EHT PPDU to a receiver through a 320 MHz band in which an 80 MHz band is punctured. A legacy preamble includes an L-STF and an L-LTF. The legacy preamble is generated by applying a first phase rotation value. The first phase rotation value is determined on the basis of a first scheme and a second scheme. The first scheme is a scheme of obtaining an optimal PAPR in the L-STF and the L-LTF. The second scheme is a scheme of obtaining an optimal PAPR on the basis of the maximum transmission bandwidth supported by the RF. The first phase rotation value is obtained on the basis of a second phase rotation value and a third phase rotation value. The second phase rotation value is a phase rotation value that repeats a phase rotation value defined for the 80 MHz band in an 802.11ax system. The third phase rotation value is a phase rotation value defined in units of the 80 MHz band in the 320 MHz band.

The apparatus transmits the multiple slot PUSCH transmission with multiplexed UCI.

Techniques for autonomous uplink (AUL) transmissions are provided that allow for efficient use of shared radio frequency spectrum band resources. A user equipment (UE) may determine a duration of an AUL transmission and modify an uplink waveform or provide an indication to a base station of one or more channel resources that may be available for base station transmissions, in order to more fully utilize shared radio frequency spectrum band resources within a maximum channel occupancy time (MCOT). A base station may activate or deactivate AUL transmissions through downlink control information (DCI) transmitted to the UE. A UE and base station may exchange various other control information to provide relatively efficient autonomous uplink transmissions and use of the shared radio frequency spectrum band resources.
