A first radio base station informs a second radio base station about the configuration information of a second carrier, such as NBC or EC, not having an individual first identifier, as the configuration information of the second carrier is correlated with a first carrier, such as BC, having the individual first identifier. The radio station has a function of performing communication with a radio terminal using simultaneously a plurality of carriers included in the carrier set.

A method by which a terminal reports channel state information (CSI) in a wireless communication system, according to one embodiment of the present invention, comprises the steps of: measuring interference through an interference measurement resource (IMR) set in a control area; and reporting, to a base station, CSI for the control area on the basis of the result of the interference measurement, wherein the CSI for the control area includes information on quality of a downlink control channel set through at least one control channel element (CCE) aggregation, and the information on the quality of the downlink control channel can include information on at least one CCE aggregation level preferred by the terminal in order to receive the downlink control channel. A UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.

A network device may receive data for multiple wireless channels. The network device may determine an activity level or score for one or more of the wireless channels based on the received data. The network device may determine, based on the activity level for each wireless channel, a portion of the wireless channels that satisfy an activity level threshold. The network device may generate a ranking of the portion of the wireless channels that satisfy the activity level threshold. The ranking may be based on the activity level or score of each wireless channel. The network device may determine a wireless channel based on the ranking and may send an indication of the wireless channel to a user device.

Certain aspects of the present disclosure provide techniques for channel state information (CSI) reporting based on user equipment (UE) parameters. A method that may be performed by a UE includes receiving a configuration to report aperiodic CSI. The method generally includes determining, based on one or more parameters, to send a first report including hybrid automatic repeat request (HARQ) feedback and not CSI feedback or a second report including HARQ feedback and CSI feedback. The method generally includes sending the first report or the second report based on the determination.

A base station device includes a communication circuit configured to receive a first signal from an external base station device and transmit a second signal to a user equipment, by using a plurality of antennas, and a processor configured to obtain resource allocation information of the external base station device based on the first signal, identify whether an interference cell occurs, and generate the second signal when the interference cell occurs, the second information including resource allocation information of the interference cell.

Provided are a signal transmission method and apparatus. The method includes the following steps: first signaling is configured, a slot for sending a reference signal is determined according to the first signaling, and the reference signal is sent on the slot for sending the reference signal.

In an embodiment a supplementary uplink (SUL) configuration method includes determining, by an access network device, a plurality of synchronization signal blocks (SSBs), wherein each of the plurality of SSBs comprises configuration information of one SUL and broadcasting, by the access network device, the plurality of SSBs on a downlink.

Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives a sounding reference signal (SRS) resource configuration, the SRS resource configuration indicating at least a comb pattern for at least one SRS resource allocated to the UE and a puncturing unit for the comb pattern, wherein the comb pattern is divided into one or more puncturing units, wherein each puncturing unit comprises one or more time units of the comb pattern, and wherein each of the one or more time units comprises two or more symbols, and refrains from transmitting all SRS transmissions of the at least one SRS resource within a first puncturing unit of the one or more puncturing units based on a determination that one or more SRS transmissions of the at least one SRS resource within the first puncturing unit are to be dropped.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station via the transceiver, an indication to apply an amplitude drooping based at least in part on an uplink band being adjacent to a downlink band in a full-duplex operation. The UE may transmit, to the base station via the transceiver, an uplink transmission in the uplink band based at least in part on the amplitude drooping. Numerous other aspects are described.

A capability information reporting method, relevant devices and a system are provided. The capability information reporting method includes: acquiring a predicted frequency range of an intra-UE interference; and receiving intra-UE interference suppression capability information with respect to the intra-UE interference from the UE. The intra-UE interference suppression capability information includes intra-UE interference suppression capability information about the UE within the predicted frequency range.
