A method, wireless device and network node for CSI feed-back with multiple interference hypotheses are disclosed. According to one aspect, a method implemented in a wireless device (WD) includes receiving a configuration for Channel State Information (CSI) measurement including a first Non-Zero Power Channel State Information-Reference Signal (NZP CSI-RS) resource set for channel measurement and a second NZP CSI-RS resource set for interference measurement, the first NZP CSI-RS resource set having only one NZP CSI-RS resource. The method also includes measuring CSI based on the first and the second NZP CSI-RS resource sets.

Provided in the present disclosure are an uplink control information transmission method and device. The method includes determining that a first transmission resource corresponding to uplink data to be transmitted and a second transmission resource corresponding to uplink control information to be transmitted overlap in a time domain. The method also includes transmitting the uplink control information on the second transmission resource and terminating transmission of the uplink data on the first transmission resource.

Dynamic reconfiguration of CSI-RS resources for CSI reporting is described for full dimension multiple input, multiple output (FD-MIMO) systems. While a larger number of channel state information (CSI) reference signal (CSI-RS) resources with independent resource configuration are configured and associated with a CSI process, only a subset of resources that are activated by additional signaling are used for CSI measurement and reporting. The set of activated CSI-RS resources may include only a single CSI-RS resource. Both periodic and aperiodic CSI reporting may then be based on the same set of the activated CSI-RS resources. Medium access control (MAC) control elements may be used to provide activation/deactivation of the CSI-RS resources. Additionally, CSI reporting may be based on both the activated CSI-RS resources and the associated number of antenna ports.

A method performed by a terminal in a wireless communication system includes: receiving, from a base station, configuration information associated with a channel state information (CSI) report including at least one information associated with a CSI resource setting; receiving, from the base station, information associated with channel occupancy duration; determining whether at least one symbol for receiving a channel state information reference signal (CSI-RS) is within channel occupancy duration, based on the at least one information associated with the CSI resource setting and the received information associated with the channel occupancy duration; receiving, from the base station, at least one CSI-RS on the at least one symbol, based on a result of the determining; and when the CSI report is determined to be transmitted, transmitting; to the base station, the CSI report based on the configuration information associated with the CSI report and the received at least one CSI-RS.

The information feedback method may include: receiving a downlink data transmission instruction sent by a second communication node; and triggering, according to the downlink data transmission instruction, the first communication node to feed back demodulation capability information and channel state information (CSI) to the second communication node; the CSI may include: a signal-to-noise ratio (SNR) and an SNR change rate of a received signal.

Described are embodiments for uplink beam reporting. A wireless device determines an overlap in time between: a first uplink channel resource of a permissible exposure report for a cell and a second uplink channel resource of a channel state information (CSI) report for the cell. Based on the determined overlap in time, the wireless device drops the CSI report scheduled for transmission via the second uplink channel resource, and transmits the permissible exposure report via the first uplink channel resource.

Various aspects of the present disclosure generally relate to multi-slot transmission time interval based channel state information (CSI) and uplink shared channel (UL-SCH) multiplexing. In some aspects, a user equipment (UE) may receive a downlink control information (DCI) message and determine, based at least in part on the DCI message, a schedule for multiplexing UL-SCH data and one or more components of uplink control information (UCI) in a plurality of slots on a physical uplink shared channel (PUSCH). The components may include a CSI report for a plurality of transmission reception points. The UE may multiplex the UL-SCH data and the one or more components into the plurality of slots based at least in part on the schedule. Numerous other aspects are provided.

The present disclosure provides a method in a network device serving a first cell and a second cell. The method includes: determining that a first User Equipment, UE, in the first cell and a second UE in the second cell are associated with one physical terminal device; and enabling, in response to said determining, the terminal device to perform as the first UE, without enabling the terminal device to perform as the second UE, one or more of: measuring a reference signal from the network device, transmitting a reference signal to the network device, or transmitting a measurement report to the network device.

A terminal according to one aspect of the present disclosure includes: a receiving section that receives configuration information indicating whether or not to include an identifier of a panel related to a CSI report in the CSI report; and a transmitting section that transmits the CSI report including the identifier of the panel when the configuration information is received. According to one aspect of the present disclosure, a panel specific CSI report can be appropriately used.
