Adaptive CSI reporting and PRB bundling in AAS

A base station configured to communicate with a User Equipment, UE, the base station comprising:

• processing circuitry;
• and
• memory coupled to the processing circuitry and having instructions stored therein that are executable by the processing circuitry to cause the base station to:
• obtain one or more parameters comprising:
• (a) one or more measurements of channel dispersiveness of a wireless channel between the base station and a UE, (b) an uplink power-limited status of the UE, (c) an allocation bandwidth for the UE, or a combination two or more of (a), (b), and (c);
• select, based on the one or more parameters, a Channel State Information, CSI, report configuration for the UE, a Physical Resource Block, PRB, bundling configuration for the UE, or both the CSI report configuration for the UE and the PRB bundling configuration for the UE;
• and
• transmit, to the UE, information that indicates the selected CSI report configuration, information that indicates the selected PRB bundling configuration, or both the information that indicates the selected CSI report configuration and the information that indicates the selected PRB bundling configuration, wherein:
• the one or more parameters comprise one or more measurements of channel dispersiveness of the wireless channel;
• and
• the one or more measurements of the channel dispersiveness of the wireless channel comprise a measurement of a long-term channel dispersiveness of the wireless channel, a measurement of instantaneous channel dispersiveness of the wireless channel, or both a measurement of a long-term channel dispersiveness of the wireless channel and a measurement of instantaneous channel dispersiveness of the wireless channel.
