Patent number: 8953476Abstract: A method for scheduling a first user equipment, UE, with a first performance causing a first self interference of a relay system between a first access link extending between the relay system and the first UE and a relay link extending between the relay system and a base station, BS, and scheduling a second UE with a second performance causing a second self interference of the relay system between a second access link extending between the relay system and the second UE and the relay link extending between the relay system and the BS. Thereby, if the first self interference is larger than the second self interference, the first performance is smaller than the second performance. Alternatively, if the first self interference is smaller than the second self interference, the first performance is larger than the second performance.Type: GrantFiled: November 3, 2009Date of Patent: February 10, 2015Assignee: Nokia Siemens Networks OyInventors: Zhu Yan Zhao, Simone Redana, Bernhard Raaf

Patent number: 8954078Abstract: A method, apparatus, and computer program for continuing transmission during handover are presented. A communication connection is established between a source base station and a mobile relay base station comprising a distributed antenna system (DAS). The DAS includes multiple spatially distributed antenna units (DAUs), wherein at least part of the DAUs are used for forming a cluster of sub-cells within a coverage area of the mobile relay base station and at least part of the DAUs are used for communicating with a fixed cellular network infrastructure over multiple backhaul links. A first backhaul link is then handed over from the source base station to a target base station. After the handover, data transfer between the source base station and at least one backhaul link still linked to the source base station is continued, and remaining backhaul link(s) are released from the source base station according to a determined criterion.Type: GrantFiled: December 2, 2009Date of Patent: February 10, 2015Assignee: Nokia Siemens Networks OyInventors: Vinh Van Phan, Ling Yu, Kari Veikko Horneman, Jaakko Eino Ilmari Vihriala, Matti Tapani Kiiski, Olli Juhani Piirainen, Markku Juha Vainikka

Patent number: 8955051Abstract: A method is proposed, for use e.g. in the context of WiMAX networks supporting the CMIPv6 function, for allowing the ASN-GW to become aware of the status of a control procedure, the CMIPv6 mobility binding procedure. The ASN-GW is not directly aware of its result since the procedure implies a message exchange at the U-Plane level, where the ASN-GW implements only a routing function. Nevertheless the ASN-GW needs to know the status of the procedure since it has to perform some subsequent actions depending on that status. The method includes signalling the status via a signalling mechanism between the Access Service Network and the Connectivity Service Network, thus avoiding packet inspection at the U-plane by the Access Service Network Gateway.Type: GrantFiled: July 28, 2008Date of Patent: February 10, 2015Assignee: Nokia Siemens Networks OyInventor: Andrea Marzii

Patent number: 8923229Abstract: From the network perspective, an uplink resource allocation (PDCCH) is sent that grants an uplink resource to a plurality of user equipments UEs, and the allocation has an indication of a cyclic shift CS for each of the plurality of UEs. The granted uplink resource is mapped to a downlink resource (PHICH) in dependence on the indicated CS for each of the plurality of UEs. The mapping is such that for a predetermined number of UEs being allocated a same uplink resource in a single MU-MIMO uplink resource allocation grant, each pair of said predetermined number of UEs which map to an adjacent downlink resource exhibit an optimized CS relative to one another. The network sends to each of the respective plurality of UEs on the respective mapped downlink resource an indication (ACK/NACK) about data received (on a PUSCH).

Patent number: 8913972Abstract: The specification and drawings present a new method, apparatus and software related product for antenna clustering for multi-antenna aperture selection (MAAS), e.g., in LTE wireless systems, using multi-core DSP processing with sub-optimum selection of N out of M of antenna signals and minimizing the performance degradation due to the sub-optimal antenna/antenna signal selection. Assigning each DSP core (machine) to N/K antennas (i.e., to antenna signals) having a similar property (e.g., polarization) and a same tier, the selection of N out of M using a predefined criterion (e.g., best SINR) is reduced to selecting N/K out of M/K which reduces the computation complexity by a factor of K, where K is a number of the DSP cores.Type: GrantFiled: October 11, 2012Date of Patent: December 16, 2014Assignee: Nokia Siemens Networks OyInventors: Yehuda Luz, Philip Fleming, Shirish Nagaraj
