Abstract: Described is an apparatus of an eNB operable to communicate with a UE on a wireless network. The apparatus may comprise a first circuitry, a second circuitry, a third circuitry, and a fourth circuitry. The first circuitry may be operable to process a first transmission carrying a DM-RS antenna port group indicator and a second transmission carrying an antenna port configuration indicator. The second circuitry may be operable to select a DM-RS antenna port group comprising a set of antenna port configurations based upon the DM-RS antenna port group indicator. The third circuitry may be operable to select an antenna port configuration out of the set of antenna port configurations based upon the antenna port configuration indicator, the antenna port configuration comprising one or more DM-RS antenna ports. The fourth circuitry may be operable to process a third transmission carrying DM-RS in accordance with the selected configuration.

Abstract: An apparatus configured to be employed in a victim transmission reception point (TRP) associated with a new radio (NR) communication system is disclosed. The apparatus comprises a memory interface and a processing circuit. In some embodiments, the processing circuit is configured to process one or more predefined interference signals respectively received from one or more interfering TRPs during a guard period of the victim TRP. In some embodiments, the guard period comprises a time period between a downlink (DL) transmission and an uplink (UL) transmission associated with a time division duplex (TDD) frame of the victim TRP. In some embodiments, the processing circuit is further configured to determine an inter-TRP interference based on the one or more predefined interference signals. In some embodiments, the inter-TRP interference comprises a measurement of a UL interference at the victim TRP from the one or more interfering TRPs.

Abstract: Provided herein are a method and an apparatus for interference measurement using a beam management reference signal (BM-RS). The disclosure provides an apparatus for a user equipment (UE), comprising circuitry configured to: decode one or more beam management reference signals broadcasted by a Transmission Reception Point (TRP) in a cell, wherein the one or more beam management reference signals are used by the TRP to perform beam management for respective one or more other UEs in the cell; and measure interference from the one or more other UEs in the cell based on the decoded one or more beam management reference signals. According to some embodiments, the overhead for the interference measurement can be reduced since it is not necessary to allocate a separate CSI-RS for the purpose of interference measurement.
