Patent number: 9801106Abstract: A method in a wireless communication network for assisting a user equipment to receive signals from a target access node. The wireless communication network comprises the target access node, the user equipment and a serving access node serving the user equipment. The serving access node sends information about time instances to the user equipment. The time instances are scheduled for sending signals from the target access node in a beam direction towards the user equipments. The time instances may be determined in the target access node based on its own position and a position of the user equipment and/or a beam direction of the serving access node. The time instances may also be determined in the serving access node based on its own position and a schedule of the target access node on beam directions versus transmission times. The user equipment receives signals from the target access node during the time instances indicated in the received information.Type: GrantFiled: January 22, 2014Date of Patent: October 24, 2017Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (publ)Inventors: Robert Baldemair, Bengt Lindoff, Yngve Selen, Anders Wallen, Leif Wilhelmsson

Patent number: 9743405Abstract: The technology disclosed provides the ability for a subframe to be configured as a “flexible” subframe. As a result, at least three different types of subframes in a TDD system may be configured: a downlink (“DL”) subframe, an uplink (“UL”) subframe, and a “flexible” subframe. While the DL and UL subframes are preconfigured for each frame instance, the flexible subframes are dynamically allocated to be an uplink subframe in one instance of a frame and a downlink subframe in another instance of the frame.Type: GrantFiled: April 18, 2016Date of Patent: August 22, 2017Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Stefan Parkvall, David Astely, Erik Dahlman, Johan Nyström, Imadur Rahman, Yngve Selén, Johan Sköld

Patent number: 9204418Abstract: This document discloses solutions for using a mix of reference signal types in a wireless communications network, e.g., a first type and a second type, in making positioning-related measurements. In one example, a UE uses a “mix” of CRS and PRS. As an example case, a UE receives PRS and, possibly, CRS from one or more cells, while it receives only CRS from one or more other cells. In this case, the UE determines, e.g., received signal timing values for CRS as received from some cells, on a per-cell basis, and for PRS as received from other cells, on a per-cell basis. The UE can measure and report on per-signal/per-cell basis and can perform calculations involving a mix of timing measurements made for both CRS and PRS. In a further aspect, reference signal transmissions are controlled or coordinated on a per-port basis in cells that use multiple antenna ports for transmitting within each such cell.Type: GrantFiled: January 30, 2014Date of Patent: December 1, 2015Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Iana Siomina, Yngve Selén
