Publication number: 20220182203Abstract: A set of different pilot structures are designed for use in different environments and/or different user behaviours that are expected to occur in a cell. The radio conditions for a user are estimated. Each user is then assigned an area (108A-E) in resource space for its communication, which has a suitable pilot configuration. In one embodiment, the entire resource space is provided with different pilot structures in different parts (110A-D) In advance and allocation of resources to the users are then performed in order to match estimated radio conditions to the provided pilot structure. In another embodiment, allocation is performed first, and then the actual pilot structure is adapted within the allocated resource space area to suit the environmental conditions.Type: ApplicationFiled: February 24, 2022Publication date: June 9, 2022Inventors: Johan NYSTRÕM, Pàl FRENGER, Erik DAHLMAN, Svante SIGNELL, Gõran KLANG

Patent number: 7778342Abstract: Communication in a MIMO network is optimized by selecting a first set of users comprising at least one user, selecting a second set of users not comprised in the first set, adapting communication parameters for the first set of users according to a first principle suitable, e.g. SVD, adapting communication parameters for the second set of users according to a second principle, e.g. opportunistic MIMO, and transmitting to the first set of user terminals according to the first communication parameters and to the second set of user terminals according to the second communication parameters. In this way, communication with one or a few users can be optimized while network resources can be used in an efficient way also for other users.Type: GrantFiled: September 22, 2004Date of Patent: August 17, 2010Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Peter Larsson, Svante Signell, David Astely

Patent number: 6611569Abstract: A down-converter converts an amplitude modulated high frequency signal into a low frequency or baseband signal. A first mixer (30, 32) mixes the high frequency signal into a composite signal having an in-phase component and a quadrature component. A complex bandpass filter (34) bandwidth limits the composite signal into a bandwidth limited signal with an in-phase component and a quadrature component. A second mixer (36, 38) mixes the bandwidth limited signal into an intermediate signal with an in-phase component and a quadrature component, and an adder (40) adds one component of the intermediate signal to the other. A similar up-converter performs the reverse process.Type: GrantFiled: October 2, 1998Date of Patent: August 26, 2003Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Thorsten Schier, Svante Signell

Patent number: 6546061Abstract: A base station in a radio telecommunication system, transforms real digital wideband high-frequency signals into a set of complex digital baseband signals and vice versa. The base station receives a set of complex digital baseband signals having an “I” and a “Q” components. A portion of these signals are modulated and then converted into complex digital high-frequency signals. The complex digital high-frequency signals are then filtered via bilinear digital ladder bandpass filters to retrieve real digital narrowband high-frequency signals. The outputs of these filters are the same corresponding “I” and “Q” components at the narrowband frequencies. These signals are further combined to form real digital wideband high-frequency signals. Finally, the combined signals are converted through a D/A converter to real analog wideband high-frequency bandpass signals.Type: GrantFiled: February 5, 2001Date of Patent: April 8, 2003Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Svante Signell, Thorsten Schier
