Patent number: 12075266Abstract: There is provided mechanisms for handling a deteriorating AP-to-AP wireless link in an IAB network. A method is performed by a first AP in the IAB network. The method comprises identifying signal deterioration of a first AP-to-AP wireless link between the first AP and a second AP in the IAB network. The first AP-to-AP wireless link is used for backhauling data for CPEs served by the second AP and for backhauling data for CPEs served by a third AP in the IAB network. The second AP has a second AP-to-AP wireless link to the third AP for backhauling data for the CPEs served by the third AP. The method comprises, in response thereto, relaying the data via a first CPE of the CPEs served by the second AP on a first direct wireless link between the first AP and the first CPE.Type: GrantFiled: November 2, 2018Date of Patent: August 27, 2024Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Behrooz Makki, Mona Hashemi, Mikael Coldrey

Patent number: 11722234Abstract: An adaptive receiver for UEs using NOMA-based schemes. One objective is to improve the achievable rate of the weak UE and improve the fairness among the grouped UEs. At the same time, an embodiment gives the chance to reduce the error probability of the strong UE. Thus, compared to conventional NOMA, an embodiment increases the network sum throughput.Type: GrantFiled: April 6, 2018Date of Patent: August 8, 2023Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Behrooz Makki, Ali Behravan, Mona Hashemi

Patent number: 11394487Abstract: An adaptive receiver system for UEs using NOMA. For example, a network node (e.g, an access point, such as a base station) obtains a first set of data points for a first decoding scheme, each data point included in the first set of data points identifying a maximum achievable rate for the first UE and a maximum achievable rate for the second UE. The network node uses the first set of data points, a first rate demand for a first UE, and a second rate demand for a second UE to determine a decoding scheme for decoding a message transmitted by one of the first UE and a transmission point of the network node.Type: GrantFiled: April 6, 2018Date of Patent: July 19, 2022Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Behrooz Makki, Ali Behravan, Mona Hashemi

Patent number: 11375342Abstract: A CSI-constrained UE grouping system for dense uplink NOMA systems. For example, a network node (e.g., an access point, such as a base station) determines which UEs should be grouped based on the uplink (UL) rate demand (UL traffic demand), and sends appropriate parameters to those UEs for UL transmission.Type: GrantFiled: February 15, 2018Date of Patent: June 28, 2022Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Behrooz Makki, Ali Behravan, Mona Hashemi

Patent number: 11368878Abstract: The present invention describes a radio base station and a method for integrated access and backhaul by using backhaul capacity requests. The radio base station is configured to allocate a first part of its capacity to access traffic and a second part of its capacity to backhaul traffic. It is further configured to form a self-backhauled network with a plurality of other radio base stations and select a backhaul route through the self-backhauled network for uplink and downlink backhaul traffic.Type: GrantFiled: September 20, 2017Date of Patent: June 21, 2022Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Mona Hashemi, Mikael Coldrey, Henrik Sahlin

Patent number: 11252736Abstract: A method for transmit timing adjustment by a second network node includes obtaining an indication of beam link failure of a current beam that is used for ongoing communication with a first network node. The method further includes switching over to a backup beam of the current beam for continuing the ongoing communication with the first network node, and adjusting transmit timing for transmitting a signal as part of the ongoing communication in the backup beam based on earlier communicated timing information with the first network node before making any transmission of the signal on the backup beam.Type: GrantFiled: April 26, 2018Date of Patent: February 15, 2022Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Mona Hashemi, Henrik Sahlin, Per-Erik Eriksson, Behrooz Makki, Lei Bao, Andreas Nilsson, Mikael Coldrey
