1. A method comprising:
transmitting, by a base station to a User Equipment (UE), signaling indicating a first Time Division Duplexing (TDD) UpLink-DownLink (UL-DL) configuration, wherein a TDD UL-DL configuration is defined over a time period of ten SubFrames (SFs) that comprise DL SFs where a communication direction is from the base station to the UE, UL SFs where a communication direction is from the UE to the base station, and special SFs where a communication direction can be both from the base station to the UE and from the UE to the base station, and wherein each SF of the ten SFs has a unique time domain index; and transmitting, by the base station, a control channel configured to convey a DL Control Information (DCI) format indicating an adaptation of the first TDD UL-DL configuration to a second TDD UL-DL configuration;
configuration information for:
resources of a non-zero power Channel State Information Reference Signal (CSI-RS)resources of a first Channel State Information Interference Measurement (CSI-IM), andresources of a second CSI-IM wherein the non-zero power CSI-RS resources, the first CSI-IM resources and the second CSI-IM resources are respectively in a SF that is a DL SF, the DL SF, and an UL SF in the first TDD UL-DL configuration; wherein a system information block (SIB) indicating the first TDD UL-DL configuration, the DCI format indicating the second TDD UL-DL configuration, the configuration information is configured to cause the UE to measure a first quantity based on signaling received in the non-zero power CSI-RS resources and on the first CSI-IM resources and a second quantity based on signaling received in the non-zero power CSI-RS resources and on the second CSI-IM resources when the UL SF is a DL SF in the second TDD UL-DL configuration. |
