Publication number: 20240063938Abstract: A method is performed by a network node for handling link adaptation for a communication between the network node and a User Equipment, UE, in a wireless communications network. The method comprises: obtaining an initial Information Carrying Capacity, ICC, estimate; and establishing a measurement at each Hybrid Automatic Repeat Request, HARQ, feedback on an initial transmission in the communication. The measurement comprises a Block Error Rate, BLER, per: rank, Modulation and Coding Scheme, MCS, and slot. Based on the established measurement it is determining whether or not to adjust the initial ICC estimate, and whether or not to disable outer loop ICC adjustments. The determining is to be used as a basis for the link adaptation of said communication. A corresponding network node is also presented.Type: ApplicationFiled: March 11, 2022Publication date: February 22, 2024Inventors: Aleksandar Jovanovic, Ahmedul Quadir, David Better

Patent number: 11848786Abstract: A method and a status manager for controlling status reporting from a data receiving node in a wireless communication of data with a data sending node. When detecting that the data receiving node should transmit a status report to the data sending node before a prescribed time limit expires, the data receiving node is triggered to transmit the status report either together with data if the data is pending for transmission from the data receiving node when the time left before the prescribed time limit is greater than a minimum duration, or alone if no data is pending when the time left before the time limit becomes shorter than the minimum duration.Type: GrantFiled: May 2, 2019Date of Patent: December 19, 2023Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Christian Skärby, David Better, Johnny Karlsen

Publication number: 20230224954Abstract: A network node is configured with a common preamble format for a shared spectrum comprising a first Radio Access Technology (RAT) and a second RAT. The RACH procedure is common for the first and second RAT. The network node configures the network node with a common preamble location in time and frequency for the first and second RAT. The network node configures the UE with a preamble group comprising a number of preambles distributed between the first and second RAT for the common preamble format. When receiving from the UE, a first RACH message comprising a first preamble at the common preamble location according to the UE configuring, the network node decides whether the first RAT, the second RAT, or both the first and second RAT, shall be used for a second RACH message to be sent to the UE.Type: ApplicationFiled: June 18, 2020Publication date: July 13, 2023Inventors: Ahmedul QUADIR, David BETTER

Patent number: 11233616Abstract: A method performed by a network node for managing transmission of one or more CRS subframes. The network node identifies if a cell is actively serving a set of UEs. When the cell is actively serving a set of UEs, which set of UEs is configured for DRX the network node sends CRS over the first bandwidth in one or more CRS subframes which are transmitted in the cell during an onDuration interval of the DRX pattern and/or in one or more CRS subframes where system information is sent and/or in one or more CRS subframes where downlink, DL, data is sent. The network node sends CRS over a second bandwidth, in CRS subframes which are not transmitted in the cell during the onDuration interval of the DRX and/or in the one or more CRS subframes except CRS subframes where system information is sent and/or in the one or more CRS subframes except CRS subframes where DL data is sent, which second bandwidth is reduced in relation to the first bandwidth.Type: GrantFiled: September 16, 2019Date of Patent: January 25, 2022Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: David Better, Tomas Lagerqvist, Peter Nordlund, Anthony Paravati

Patent number: 10694474Abstract: Method performed by a network node for reducing interference in neighboring cells. The network node operates in a communication network, which is adapted to wirelessly serve a UE via a serving Radio Access, RA, node.

Patent number: 9161350Abstract: Embodiments herein relates to a method in a radio base station (12) for handling a timing of uplink transmission from a user equipment (10) to the radio base station (12) in a radio communications network. The user equipment (10) is served in a cell (14) controlled by the radio base station (12), and which radio base station (12) and user equipment (10) are comprised in the radio communications network. The communications in the cell (14) are organized in radio frames comprising subframes. The radio base station (12) receives a first uplink transmission from the user equipment (10) in a subframe related to the radio base station (12). The radio base station then estimates a time parameter value based on a distance between the user equipment (10) and the radio base station (12) when the first uplink transmission is transmitted from the user equipment (10).Type: GrantFiled: December 30, 2010Date of Patent: October 13, 2015Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: David Better, Franz Heiser, Tobias Tynderfeldt
