Publication number: 20240080927Abstract: A wireless communication device, WCD, receives a message from a network node in a communication network. The message indicates that the WCD is to save a user equipment, UE, context of the WCD. In response to receiving the message, the WCD saves the UE context. The message also indicates that the WCD is to transition from a connected state to an inactive state when a first condition is satisfied, and/or remain in an inactive state when a second condition is satisfied. The first and/or second condition may for example include that the WCD experiences a loss of connection or loss of coverage, or that the WCD experiences a radio link failure.Type: ApplicationFiled: January 2, 2021Publication date: March 7, 2024Inventors: Jan CHRISTOFFERSSON, Andreas HÖGLUND, Mårten ERICSON

Patent number: 11895645Abstract: Systems, methods and apparatus are disclosed for user equipment and/or network nodes. An example method performed by a network node includes providing a shared resource to a plurality of user equipments (UEs) that are active on a bandwidth part (BWP). The network node receives a Scheduling Request (SR) on the shared resource of the BWP, and responsive to the SR, assigns one or more grants to one or more of the plurality of UEs that are provided with the shared resource. The network node monitors another resource, for a time window after the assigning of the one or more grants, and after receiving a transmission on the monitored resource from a UE, provides the UE with a dedicated resource on the BWP.Type: GrantFiled: August 16, 2018Date of Patent: February 6, 2024Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Mårten Ericson, Jan Christoffersson, Min Wang

Patent number: 11844089Abstract: Group transmission of data from a group of User Equipment devices to a network node of a cellular communication system where communication between devices is effected by device-to-device technology can provide significant improvements in uplink coverage and user bit rate. However, the benefits of group transmission means that not all devices of a group have sufficient network coverage to reliably receive a grant signal scheduling uplink resources from a network node. Methods, devices and a network node are proposed that enable the dynamic selection of either a direct grant mode, in which each device receives the uplink grant directly from the network, or a relayed grant mode, in which a device acting as group coordinator relays the grant to all members of the group, to ensure optimal performance for group transmissions. The selection is dependent on at least one determined condition relating to the group of devices and/or the group transmission.Type: GrantFiled: December 20, 2021Date of Patent: December 12, 2023Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Jan Christoffersson, Mårten Ericson, Min Wang

Publication number: 20230389080Abstract: A wireless communication device (12) receives a random access configuration (18) from a radio network node (14) configured to transmit multiple SSBs (16-1 . . . 16-N). The random access configuration (18) configures the wireless communication device (12) with a set (20) of one or more random access preambles. This set (20) of one or more random access preambles is not associated with any of the multiple SSBS (16-1 . . . 16-N). Upon receiving a random access preamble from this set, the radio network node (14) may transmit a random access response as a response to the random access preamble. The radio network node (14) may do so by transmitting the random access response on one or more downlink beams that are estimated from measurement of an uplink beam or uplink signal from the wireless communication device (12).Type: ApplicationFiled: September 15, 2020Publication date: November 30, 2023Inventors: Jan Christoffersson, Min Wang, Mårten Ericson

Patent number: 11832138Abstract: A method performed by a first base station, is described. The first base station determines a change in one or more measurements to be performed by a UE. The measurements are associated with a first set of frequencies. The first base station also transmits a first message to a second base station comprising information regarding which frequencies in the first set are to be changed. The first base station and the second base station serve the UE. A method performed by the second base station is also described whereby the second base station receives the first message. In a method performed by the UE, the UE receives, from the first base station, a configuration message configured to specify the measurements to perform and a measurement gap configuration. The UE then takes the measurements based on the configuration message.Type: GrantFiled: August 15, 2022Date of Patent: November 28, 2023Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Oumer Teyeb, Mårten Ericson, Pradeepa Ramachandra
