Publication number: 20240121057Abstract: A technique for transmitting and receiving a configuration message for a phase tracking reference signal, PT-RS, on a radio channel between a radio access node and a radio device is described. The radio channel comprises a plurality of subcarriers in a physical resource block, PRB. A subset of the subcarriers in the PRB is allocated to a demodulation reference signal, DM-RS. As to a method aspect of the technique, the configuration message is transmitted to the radio device. The configuration message comprises a bit field that is indicative of at least one subcarrier allocated to the PT-RS among the subset of subcarriers allocated to the DM-RS.Type: ApplicationFiled: December 5, 2023Publication date: April 11, 2024Inventors: Vicent Molés Cases, Mattias Frenne

Patent number: 11201640Abstract: Methods and apparatuses are disclosed for PT-RS selection. In one embodiment, a wireless device is configured to determine a layer based at least on a precoder associated with a precoder matrix indicator, PMI; and transmit an indication of the determined layer to a network node as part of channel state information, CSI, feedback. In other embodiments, a network device is configured to receive an indication of a layer for a phase-tracking reference signal, PT-RS, transmission as part of channel state information, CSI, feedback; determine a precoder based at least on the indication of the layer for the PT-RS transmission; and transmit the PT-RS, the PT-RS transmission associated with the indicated layer and a PT-RS port.Type: GrantFiled: June 27, 2018Date of Patent: December 14, 2021Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Vicent Molés Cases, Mattias Frenne, Lars Lindbom, Karl Werner
