Patent number: 9578526Abstract: A method and a network node (110) for determining an indication of interference mitigation in a receiver comprised in a user equipment (120) are provided. The network node (110) receives, from the user equipment (120), a first set of measures and a second set of measures. The first set of measures relates to a signal received by the user equipment (120) and the second set of measures relates to the same signal. The first set of measures was obtained by the user equipment (120) prior to processing of the signal in the receiver, and the second set of measures was obtained by the user equipment (120) after processing of the signal in the receiver. Next, the network node (110) determines (202) the indication of interference mitigation based on the first and second sets of measures.Type: GrantFiled: October 26, 2011Date of Patent: February 21, 2017Assignee: TELEFONAKTIEBOLAGET L M ERICSSONInventors: Jawad Manssour, Konstantinos Dimou, Kristina Jersenius

Patent number: 9564978Abstract: The present invention relates to a method, user equipment and a base station adapted to handle channel state feed-back reports in a more flexible way. More specifically, a channel state feedback procedure is provided which utilizes the resources available for transmission of channel state feedback more efficiently. This is achieved by including uplink grant availability into the channel state feedback reporting triggers used for determining when and how to send channel state feedback from a UE, i.e. a channel state feedback reporting request may be sent by a base station in an uplink grant to a UE comprising an indication of an expected amount of information to be returned.Type: GrantFiled: October 30, 2014Date of Patent: February 7, 2017Assignee: IDTP HOLDINGS, INC.Inventors: Kristina Jersenius, Eva Englund, Pal Frenger

Patent number: 9526087Abstract: The present invention relates to allowing configuring CSI reporting (step S-224, 310) on radio resources that are allocated over a plurality of sub frames on Physical Uplink Shared Channel (PUSCH). Allocation of said radio resources (steps S-202, 404) can be performed by semi-persistent allocation or by using Transmission Time Interval (TTI) bundling. By using either semi-persistent scheduling or TTI-bundling as decided by an eNB (104, 204, 600) the UE (102, 202, 500) can be configured to report CSI (step S-224, 310) for a plurality of UL transmissions. By allocating radio resources by using semi-persistent scheduling, the signaling overhead, which can be substantial for dynamic scheduling of radio resources, decreases. By using TTI-bundling the coverage of the CSI-reports increases.Type: GrantFiled: April 18, 2014Date of Patent: December 20, 2016Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Eva Englund, Erik Eriksson, Kristina Jersenius, George Jongren, Peter Moberg, Stefan Parkvall

Publication number: 20160219526Abstract: Transmit power control methods and apparatus are disclosed. In several embodiments, a mobile terminal is configured to effectively ignore “UP” transmit power control commands in the event that the mobile terminal is operating in a power-limited state. In an exemplary method for controlling transmit power at a mobile terminal, a plurality of transmit power control commands are received. An accumulated power control value is adjusted in response to each transmit power control command that directs a negative adjustment in transmit power. However, the accumulated power control value is adjusted in response to a transmit power control command that directs a positive adjustment in transmit power only if the mobile terminal is not in a power-limited state. Transmit power settings for each transmission are calculated based on the accumulated power control value and the one or more radio link parameters.Type: ApplicationFiled: April 5, 2016Publication date: July 28, 2016Inventors: Eva Englund, Erik Dahlman, Anders Furuskär, Ylva Jading, Kristina Jersenius, Stefan Parkvall
