Patent number: 9894585Abstract: A method in a base station for handling sector selection is provided. A wireless terminal is connected to a first sector comprised in a combined cell. When a quality of the communication resources in the first sector is below a first threshold, the base station determines that the first sector is no longer the best sector for the wireless terminal. Then the base station sends an order to the wireless terminal to initiate a random access procedure in the combined cell. The base station then selects a second sector in the combined cell based on measurements of signal strength of random access preambles received from the wireless terminal in each respective sector in the combined cell. The random access preambles are received from the wireless terminal in the initiated random access procedure. The second sector is selected for the wireless terminal to communicate in.Type: GrantFiled: February 4, 2014Date of Patent: February 13, 2018Assignee: TELEFONAKTIEBOLAGET L M ERICSSON (PUBL)Inventors: Alexander Langereis, Marco Belleschi, Jawad Manssour

Patent number: 9326151Abstract: A method in a base station for assisting in a coordination of frequency band selections for interfering uplink transmissions in a cellular network. The base station selects a first frequency band and a second frequency band. The first frequency band is to be used in the first cell for uplink transmissions from which an estimated interference in a second cell exceeds a first threshold. The second frequency band is to be used in the first cell for uplink transmissions from which an estimated interference in a third cell exceeds a second threshold. The base station informs a serving base station of the second cell and a serving base station of the third cell about the selection, thereby assisting these base stations in coordinating their respective frequency band selection with that of the base station.Type: GrantFiled: July 21, 2011Date of Patent: April 26, 2016Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventor: Jawad Manssour

Patent number: 9325465Abstract: A method and base station (600) of a first cell (602), for—controlling inter-cell interference in a cellular network when Discontinuous Reception, DRX, is applied for User Equipments, UEs. The base station selects a DRX scheme with active periods that are separated in time from active periods of a DRX scheme used for UEs in DRX mode in a neighboring second cell (806). The selected DRX scheme is then used for a first UE (604) in DRX mode in the first cell to avoid interference between transmissions of signals in the active periods to the first UE in the first cell and transmissions of signals in active periods to the UEs in the neighboring second cell.Type: GrantFiled: May 4, 2012Date of Patent: April 26, 2016Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Hongwei Wang, Jawad Manssour
