Methods and apparatuses for sending and receiving CSI reports are disclosed. A method, comprising: receiving triggering information for N aperiodic Channel Suite Information (CSI) reports and the CSI reference signal (CSI-RS) resources linked with the N CSI reports, wherein N is an integer greater than 1; determining M CSI reports and calculating M CSIs each indicated by a determined CSI report according to the CSI-RS resources linked with the determined M CSI reports, wherein M is an integer than is less than N; and sending M CSI reports each indicating a calculated CSI.

A method performed by a UE is provided. The method includes receiving DCI on a PDCCH from a BS, the DCI indicating a PDSCH; receiving a MAC CE command on the PDSCH; determining, according to the DCI, whether a HARQ ACK feedback for a data reception on the PDSCH is needed to be transmitted; and applying, after determining that the HARQ ACK feedback is needed to be transmitted, the MAC CE command after a first slot identified by a first value of n+K0+K1+Np+M, where n is an index of a slot in which the DCI is received, K0 and K1 are slot offsets, Np indicates an approximated delay determined by a TA value, and M indicates a processing delay.

Wake-up signal (WUS) downlink control information (DCI) may be configured to convey a wake-up indication as well as UE wake-up behavior configuration information. For example, WUS DCI may include one or more wake-up indications for one or more UEs via wake-up indication bits (e.g., wake-up indication bits may be conveyed in locations of the WUS DCI associated with monitoring indices of the one or more UEs to be activated). For example, WUS DCI may be encoded to include a wake-up indication and an indication of behavior configuration information for a group of one or more UEs. UE wake-up behavior configuration information may indicate some BWP to activate, may trigger a CSI report, etc. A UE may decode the wake-up indication and the wake-up behavior configuration information based on a monitoring index and the WUS configuration.

The present invention relates to a method for transmitting and receiving channel quality information in a wireless communication system for supporting a Narrowband Internet of Things (NB-IoT) and a device therefor and, more particularly, the method comprising: transmitting and receiving a random access preamble; transmitting and receiving a random access response on the basis of the random access preamble; and transmitting and receiving channel quality information via a narrowband physical uplink shared channel (NPUSCH) on the basis of the random access response, wherein when the random access preamble is transmitted and received on the basis of a narrowband physical downlink control channel (NPDCCH) order in a radio resource control (RRC) connected state, the channel quality information is measured on the basis of a UE-specific search space (USS) set in the RRC connected state.

An Uplink Control Information UCI transmission method, a UCI transmission device, a terminal, and a base station are provided. The method includes: selecting one of a plurality of first UCIs as a target UCI, when there are a plurality of transmissions of first UCIs, a plurality of Physical Uplink Control Channels PUCCHs respectively carrying the first UCI do not overlap in time domain, and all of the plurality of PUCCHs carrying the first UCI overlap with a PUCCH carrying a second UCI in time domain; multiplexing the target UCI and the second UCI.

Proposed is a method for performing, by a first apparatus, wireless communication. The method may comprise the steps of: receiving, from a second apparatus, information about latency bound related to sidelink channel state information; selecting a resource to transmit the sidelink channel state information in a selection window, on the basis that a reserved resource does not exist in a time window for reporting the sidelink channel state information; and transmitting, to the second apparatus, an MAC CE including the sidelink channel state information in the time window through the selected resource. For example, the time window may be determined on the basis of the latency bound. For example, the selection window may be determined on the basis of at least one of the time window, a time offset value, or a requirement related to the sidelink channel state information.

A CSI transmission method, a method for triggering CSI transmission, and a related device are provided. The CSI transmission method includes: controlling transmission of channel state information CSI based on a data type of the CSI, where the data type includes a type that requires a hybrid automatic repeat request HARQ feedback or a type that requires no HARQ feedback.
