1. A method comprising:
transmitting, by a base station to a User Equipment (UE) for communication using Time Division Duplexing (TDD)
a System Information Block (SIB) indicating a first 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;a Physical DL Control CHannel (PDCCH) conveying 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), for resources of a first Channel State Information Interference Measurement (CSI-IM), and for resources 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 subframe that is a DL subframe, a DL subframe, and an UL subframe in the first TDD UL-DL configuration; receiving, by the UE
the SIB indicating the first TDD UL-DL configuration;the DCI format indicating the second TDD UL-DL configuration;the configuration information; and measuring, by the UE, 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 subframe is a DL subframe in the second TDD UL-DL configuration. |
