20190379505 | METHOD OF TRANSMITTING UPLINK PHASE TRACKING REFERENCE SIGNAL BY USER EQUIPMENT IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS SUPPORTING SAME - The present invention proposes a method of transmitting and receiving an uplink phase tracking reference signal between a user equipment and a base station in a wireless communication system and an apparatus therefore. | 2019-12-12 |
20190379506 | METHODS AND APPARATUSES FOR MULTI-TRP TRANSMISSION - A method performed by a User Equipment (UE) is provided. The method includes receiving Transmission/Reception Point (TRP) information from a Base Station (BS), and communicating with a plurality of TRPs based on the TRP information, where the TRP information identifies a correspondence between the plurality of TRPs and a plurality of Downlink (DL) Reference Signal (RS) resources, and where the TRP information includes at least one of a plurality of TRP Identifiers (IDs), a plurality of Control Resource Set (CORESET) IDs, or a TRP mapping table including a plurality of TRP indices and a plurality of DL RS resource indices. | 2019-12-12 |
