Patent number: 11601960Abstract: A user equipment, a network node and methods thereof for timing of scheduling of resources in a frequency division duplex system are disclosed. The user equipment and network node operate in a frequency division duplex communication system. The network node determines (400) whether a user equipment is prohibited to receive an uplink grant in at least one downlink subframe, e.g. if the user equipment is configured with ABS or with half-duplex operation. Furthermore, if the user equipment is prohibited to receive an uplink grant in at least one downlink subframe, the network node sends (410) an indication to the user equipment to apply a time division duplex configuration to the timing of scheduling of resources. The user equipment receives (420) the indication and thereupon applies (430) the time division duplex configuration to the timing of scheduling of resources.Type: GrantFiled: November 9, 2012Date of Patent: March 7, 2023Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Erik Eriksson, Andreas Bergström, Martin Hessler

Publication number: 20220393966Abstract: A method performed by a first node. The first node operates in a communications network. The first node determines, based on a header of a packet, a first number of hops. The first number of hops are the hops the packet has to traverse in the communications network to reach a second node in the communications network. The header of the packet indicates a second number of hops between the second node and a third node in the communications network in a first path. The first node obtains a wired backhaul connection to a core network of the communications network from the third node. The first node then initiates routing the packet towards the second node based on the determined first number of hops.Type: ApplicationFiled: November 23, 2020Publication date: December 8, 2022Inventors: Per-Erik ERIKSSON, Jose Luis PRADAS, Ajmal MUHAMMAD, Marco BELLESCHI, Oumer TEYAB
