Patent number: 11743832Abstract: 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: GrantFiled: June 17, 2021Date of Patent: August 29, 2023Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Eva Englund, Erik Dahlman, Anders Furuskär, Ylva Jading, Kristina Jersenius, Stefan Parkvall

Patent number: 11412537Abstract: 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 15, 2019Date of Patent: August 9, 2022Assignee: IDTP Holdings, Inc.Inventors: Kristina Jersenius, Eva Englund, Pal Frenger

Publication number: 20220039102Abstract: Scheduling requests are transmitted from a mobile terminal to a base station. The mobile sends a first scheduling request to the base station, the first scheduling request being associated with first data to be transmitted to the base station. The mobile receives a scheduling grant from the base station in response to the first scheduling request and transmits a buffer status report to the base station in response to receiving the scheduling grant. An HARQ acknowledgment for the buffer status report is received. Second data is received for transmission to the base station while at least some of the first data is waiting to be transmitted to the base station. A change in a buffer status of the mobile terminal is detected indicating that the second data has higher priority than the first data. The mobile transmits a second subsequent scheduling request to the base station in response to the change in buffer status.Type: ApplicationFiled: October 21, 2021Publication date: February 3, 2022Inventors: Kristina JERSENIUS, Henning WIEMANN, Anna LARMO, Peter MOBERG, Eva ENGLUND

Publication number: 20180302142Abstract: Culling a set of precoders down to a smaller set using a comparatively simple first-pass evaluation allows a wireless device or other entity to reduce an overall computational burden associated with identifying a currently preferred precoder. An example approach involves selecting a reduced set of precoders from a full set of precoders, based on performing preliminary evaluations of precoders in the full set, and selecting a preferred precoder or precoders from the reduced set, based on performing further evaluations of precoders in the second set. On a per precoder basis, the further evaluations are more complex than the preliminary evaluations. One may view the approach as using less complex first-pass evaluations to reduce the precoder search space, and then using more complex second-pass evaluations to identify a currently preferred precoder or precoders within the reduced search space.Type: ApplicationFiled: April 7, 2017Publication date: October 18, 2018Inventors: Jonas Fröberg Olsson, Mirsad Cirkic, Martin Hessler, Kristina Jersenius

Publication number: 20180295631Abstract: Techniques disclosed herein involve network-side and device-side operations that provide for the advantageous use of a reduced set of precoders within a larger full set of precoders. The reduced set is identified dynamically, based on characteristics of the channel between a radio network node and a wireless device, and the use of a defined mapping function that maps the reduced set of precoders within the larger full set to a reduced set of index values. Reporting precoders from the reduced set offers significant reductions in signaling overhead because of the smaller size of the index values used to index the reduced set, while simultaneously offering the ability to choose from precoders matched to current channel conditions.Type: ApplicationFiled: April 7, 2017Publication date: October 11, 2018Inventors: Jonas Fröberg Olsson, Mirsad Cirkic, Martin Hessler, Kristina Jersenius

Patent number: 9839048Abstract: Control channel quality based scheduling of radio transmissions For controlling radio transmission in a mobile network, a node (100) of the mobile network determines a channel quality of a downlink control channel of a cell (10) of the mobile network, as experienced by a certain user equipment (50-1) in the cell (10). Depending on the determined channel quality of the downlink control channel, the node (100) schedules at least one radio transmission on a data channel of the cell (10). On the downlink control channel, the node (100) indicates radio resources allocated for the scheduled at least one radio transmission.Type: GrantFiled: March 4, 2013Date of Patent: December 5, 2017Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Laetitia Falconetti, Jörg Huschke, Kristina Jersenius

Patent number: 9794812Abstract: A method and a radio network node (110) for scheduling a transmission from the radio network node (110) to a user equipment (120) are provided. The radio network node (110) obtains an indication of interference mitigation in a receiver in the user equipment (120). Next, the radio network node (110) selects a set of radio resources for the transmission based on the indication of interference mitigation, thereby scheduling the transmission.Type: GrantFiled: March 1, 2012Date of Patent: October 17, 2017Assignee: TELEFONAKTIEBOLAGET L M ERICSSONInventors: Jawad Manssour, Konstantinos Dimou, Kristina Jersenius

Patent number: 9642049Abstract: The invention relates to handover of a mobile station from a source cell to a target cell in a wireless communication network. According to the invention communication improving data in relation to communication between the source cell and the mobile station is collected by a communication improving node prior to handover and communication improving physical layer data being at least based on said collected communication improving data is transferred to a device handling communication between the target cell and the mobile station. The communication handling device then uses the communication improving physical layer data to improve the quality of the initial communication between the mobile station and the target cell after handover to the target cell.Type: GrantFiled: February 8, 2016Date of Patent: May 2, 2017Assignee: TELEFONAKTIEBOLAGET L M ERICSSON (PUBL)Inventors: Robert Karlsson, Erik Eriksson, Jonas Fröberg Olsson, Kristina Jersenius, Tomas Jönsson

Publication number: 20170099661Abstract: 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: ApplicationFiled: December 16, 2016Publication date: April 6, 2017Inventors: Eva Englund, Erik Eriksson, Kristina Jersenius, George Jöngren, Peter Moberg, Stefan Parkvall
