Example embodiments provide signaling and configuration for model-based channel state information reporting by an apparatus. Instead of reporting a table of indices or quantized values in case of a several hypotheses, coefficients of a model for requested channel state information may be reported.

Devices, methods and computer programs for compensation of residual time-frequency error(s) in communications between a network node device and a client device are disclosed. A network node device determines an auxiliary reference signal indication comprising presence information and location information of an auxiliary reference signal in a physical downlink channel transmission. The network node device transmits to the client device the auxiliary reference signal associated with a physical downlink channel in accordance with the determined auxiliary reference signal indication. The client device uses the received auxiliary reference signal for the compensation of the residual time-frequency error(s) in the communications.

Compensation of residual time-frequency errors in communications

Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for dynamic antenna port related configuration. The method comprises: receiving, at a terminal device and from a network device, a first indication of a plurality of subsets of antenna ports; and receiving, at the terminal device and from the network device, a second indication of disabling at least one of the plurality of subsets of antenna ports.

Spatial configuration adaptation

Techniques of performing CSI reporting include identifying a cluster of TRPs sharing common information in their CSI and transmitting a complete CSI report to a selected TRP of the cluster while transmitting partial CSIs reports to other TRPs of the cluster. Along these lines, in an example implementation, a UE receives a CSI-RS from a network, with the CSI-RS carrying a plurality of reference symbols from a plurality of TRPs. Based on the plurality of symbols, the UE generates TRP data representing CSI feedback for each of the TRPs. From the CSI feedback, the UE identifies, as a cluster, a subset of the TRPs that share common information within the CSI feedback. The UE then sends first identification data identifying the subset of the TRPs that make up the cluster to the network.

An apparatus for a terminal has means for storing a first configuration for measurement reporting on downlink reference signals, wherein one or more downlink reference signals correspond to one of a plurality of states for a first channel. The apparatus also has means for receiving an activation of a first state of the plurality of states for the first channel, and determining a second configuration for measurement reporting based on the first configuration for measurement reporting and the received activation of the first state, wherein the second configuration for measurement reporting configures the terminal to report measurements on a first downlink reference signal corresponding to the first state.
