A wireless device may receive an indication that repetition of downlink control information (DCI) is scheduled via a first monitoring occasion and a second monitoring occasion. The wireless device may transmit one or more feedback information bits via an uplink resource. The one or more feedback information bits may be based on a downlink assignment index (DAI) corresponding to the earlier of the first monitoring occasion and the second monitoring occasion.

A terminal includes a receiving unit configured to receive, from a base station, a message for requesting a report of a terminal capability, a control unit configured to include, into a message for reporting the terminal capability, a terminal capability related to measurement using a reference signal for obtaining information about a channel state, for each band or for each band combination, based on the message for requesting the report of the terminal capability, and a transmitting unit configured to transmit the message for reporting the terminal capability to the base station, wherein a range of a target time domain is specified in the terminal capability related to the measurement.

The present disclosure relates to a wireless communication system. Specifically, provided is a method and an apparatus for supporting same, the method comprising the steps of obtaining random access procedure-related message A, message A including a physical random access channel (PRACH) preamble and a physical uplink shared channel (PUSCH); transmitting message A; and receiving random access procedure-related message B as a response to message A, wherein the PUSCH comprises a demodulation reference signal (DM-RS), and PRACH preamble is mapped to (i) one or more DM-RS ports and (ii) one or more DM-RS sequences on the basis of indices of respective (i) one or more DM-RS ports and indices of respective (ii) one or more DM-RS sequences.

Aspects are provided which enhance receiver performance of PDCCH by allowing a base station to associate a configured PDSCH CSI-RS with a PDCCH for channel estimation and reception by a UE. A UE receives a reference signal associated with a physical downlink shared channel (PDSCH) from a base station, and uses the reference signal to receive a physical downlink control channel (PDCCH) and/or measure the PDCCH and feedback a corresponding channel measurement for the PDCCH. A base station configures a reference signal associated with a PDSCH for transmission of a PDCCH and/or reception of a corresponding channel measurement for the PDCCH as feedback from the UE, and transmits the reference signal to the UE.
