The present disclosure relates to a communication technique that merges IoT technology with a 5G communication system for supporting higher data transmission rates than 4G systems, and a system therefor. The present disclosure may be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail business, security and safety-related services, etc.) on the basis of 5G communication technology and IoT-related technology. The invention of the present disclosure proposes a method and device for transmitting and receiving a reference signal for efficiently using resources in a wireless communication system.

An operating method of a user equipment (UE) for time domain resource assignment of a data channel in a wireless communication system, the operating method including: receiving control information related to the time domain resource assignment of the data channel from a base station via a physical downlink control channel (PDCCH) and upper layer signaling, and determining the time domain resource assignment of the data channel, based on the received control information.

The present disclosure provides a method for transmitting uplink control information, a method for receiving uplink control information, a method for configuring a downlink HARQ feedback function, a terminal and a base station. The method for transmitting uplink control information comprises: transmitting uplink control information to a base station, wherein the uplink control information comprises at least one of decoding statistical information for downlink transmission, suggestion information for downlink scheduling, or channel quality related information.

A channel detection method and apparatus, a device and a user equipment are disclosed. The method includes: receiving, by a UE, a paging indication signal transmitted by a network device, where the paging indication signal is used for instructing the UE whether to detect a paging downlink control channel in K POs, the K POs are K POs after the paging indication signal is received, and K is a positive integer.

A wireless device receives a DCI indicating a first priority of a transport block and a hybrid automatic repeat request (HARQ) feedback timing of a HARQ feedback of the transport block. The wireless device switches, after receiving the DCI and before the HARQ feedback timing, from a first bandwidth part to a second bandwidth part as an active bandwidth part. The wireless device transmits or drops the HARQ feedback based on whether or not the first priority of the transport block comprises a first value.

The UE includes reception circuitry configured to receive first information, second information, a first downlink control information (DCI) on a physical downlink control channel (PDCCH), and a second DCI on a PDCCH. The UE also includes transmission circuitry configured to transmit a channel state information (CSI) report on a physical uplink shared channel (PUSCH). A CSI request field in the first DCI is configured by the first information. A CSI request field in the second DCI is configured by the second information. The first information includes trigger states for aperiodic CSI reporting for the first DCI. The CSI request field in the second DCI is configured by the second information.

Disclosed are a signal transmission method and apparatus. The signal transmission method and apparatus are used for realizing, by means of a beam for transmitting a beam failure event of a cell, the transmission of a PUCCH when a beam failure occurs in the cell. The signal transmission method provided in the present application comprises: determining that a beam failure occurs in a cell; and if a terminal needs to transmit a physical uplink control channel (PUCCH) signal, transmitting, when a preset condition is satisfied, the physical uplink control channel (PUCCH) signal by using an uplink transmission beam.

A user equipment generates an HARQ-ACK codebook comprising HARQ-ACK bits for semi-persistent scheduling (SPS) physical downlink shared channels (PDSCHs) based on multiple SPS configurations, and transmits the HARQ-ACK codebook. In the HARQ-ACK codebook, with respect to an SPS configuration index and a serving cell index, an HARQ-ACK bit for an SPS PDSCH in a slot of a lower slot index precedes an HARQ-ACK bit for an SPS PDSCH in a slot of a higher slot index, and with respect to each serving cell index, an HARQ-ACK bit for an SPS PDSCH based on an SPS configuration having a lower SPS configuration index precedes an HARQ-ACK bit for an SPS PDSCH based on an SPS configuration having a higher SPS configuration index.

A method of transmitting a sounding reference signal (SRS) by a user equipment (UE) in a wireless communication system includes receiving configuration information related to a plurality of transmission configuration indication (TCI) states, and transmitting the SRS based on a specific TCI state among the plurality of TCI states. The specific TCI state is related to one or more power control parameters for determining a transmission power of the SRS, and the one or more power control parameters are related to an SRS resource set for the transmission of the SRS.

A method, an apparatus, and a computer program product for wireless communication are provided. A base station (BS) may configure a component carrier group for a user equipment (UE). The BS may provide an indication of a spatial relation for one or more sounding reference signals associated with a component carrier of the component carrier group. The UE may receive the indication and may apply the spatial relation to the one or more sounding reference signals across bandwidth parts of component carriers of the component carrier group.
