MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202617075204 A) filed by Telefonaktiebolaget Lm Ericsson Publ on June 17, 2026, for Method For Determining A Beam For A Downlink Signal Or A Downlink Channel.
Inventors include Nilsson, Andreas; Athley, Fredrik; and Jacobsson, Sven.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: The invention refers to a method for beam determination. The method comprises transmitting (102a), by the base station (20), a configuration to the UE (10), the configuration comprising a definition of uplink reference signal resources, also referred to as UL-RS resources; transmitting (104a), by the UE (10) an uplink reference signal to the base station (20) on at least one beam using the UL-RS resources that are defined in the received configuration, wherein the uplink reference signal is received by the base station (20) from the UE (10) by using some or all of the uplink reference signal resources that are defined in the transmitted configuration; determining (105a), by the base station (20), one or more preferred beams of the at least one beam based on the received uplink reference signal of each received beam and transmitting (105) a reference signal indication to the UE (10), wherein the reference signal indication is indicating at least one UL-RS resource on which the uplink reference signal has been transmitted by the UE (10) on one of the preferred one or more beams; transmitting (106a), by the base station (20), a downlink signal and/or a downlink channel to the UE (10); and receiving (106b), by the UE (10), the downlink signal and/or the down- link channel using a beam that is based on the beam that has been used for transmitting the uplink reference signal on the UL-RS resource that is indicated in the reference signal indication.
