Publication number: 20130084849Abstract: Relative sizes of neighbor cells are identified, and measurement reporting of the neighbor cells is differentiated in dependence on at least the relative size. In one embodiment the relative sizes are identified by a frequency layer and/or physical cell identity sent by a serving cell. The differentiated reporting may be implemented by using different values, based on the relative sizes, of a measurement or reporting parameter or a scaling factor (such as Treselection or time to trigger) which adjusts either of those parameters. In one embodiment the differentiated measurement reporting is conditional on a user equipment which sends the measurement reports being classified as fast moving, and in another is further conditional on it also having no active data transfer applications ongoing. In various embodiments, detecting and measuring of small neighbor cells (and thus their reporting) is omitted, or measurements can be collected normally and only the reporting is omitted.Type: ApplicationFiled: September 30, 2011Publication date: April 4, 2013Inventors: Jussi-Pekka Koskinen, Jarkko Koskela, Lars Dalsgaard, Sari Nielsen

Publication number: 20130022095Abstract: Methods, apparatuses, and systems are provided for modem coordination. A method may include establishing a coordinated communication session with a base station on a first communication channel. The method may further include causing transmission, to the base station, of an indication of an occurrence of an irregular transmission of data on a second communication channel. The second communication channel may be with a station logically separated from the base station. The base station maybe configured to respond to the indication of the occurrence of the irregular transmission by modifying transmission on the first communication channel to avoid interfering with the irregular transmission.

Patent number: 8095134Abstract: A UE performs pilot measurements over a frequency sub-band of serving cell and adjacent cells based on pilot symbols for used in handover. UE uses channel quality measurement result to adjust frequency sub-band and periodicity of pilot measurement. In interference coordination scheme, UE is classified into cell edge or cell center UE based on channel quality measurement result. For downlink data reception, UE in cell edge is allocated cell edge frequency sub-band and UE in cell center is allocated with cell center frequency sub-band. If UE is in cell edge of the serving cell, UE also performs pilot measurement over cell edge frequency sub-band. If UE is in cell center, UE also performs pilot measurement over cell center frequency sub-band of the serving cell. When UE is located in cell edge, it performs measurement at a higher rate than when it is located in cell center.Type: GrantFiled: October 26, 2007Date of Patent: January 10, 2012Assignee: Nokia CorporationInventors: Leping Huang, Kodo Shu, Hongyuan Chen, Sari Nielsen

Patent number: 7801496Abstract: Methods, computer-readable media, and devices are provided that support antenna diversity in a communication system. In an exemplary method, a signal is received from a first device at a second device in a first channel. A determination is made concerning whether or not transmit diversity is applied to the first channel. If transmit diversity is applied to the first channel; a first channel estimate is determined based on a first pilot signal received from the first device and a second channel estimate is determined based on a second pilot signal received from the first device. The received signal is decoded based on the first channel estimate and the second channel estimate.Type: GrantFiled: March 20, 2008Date of Patent: September 21, 2010Inventors: Jorma Kaikkonen, Markku Kuusela, Sari Nielsen, Jussi Numminen

Patent number: 7529560Abstract: This invention describes a method for a cell reselection by a mobile station from a serving GERAN cell supported by a GSM/EDGE (global system for mobile communications/enhanced data rates for GSM evolution) radio access network (GERAN) to a UTRAN cell supported by a universal terrestrial radio access network (UTRAN). According to a first embodiment of the invention, the intended intersystem reselection behavior is reached without signaling changes. This can be a preferred mode for early implementations because signaling changes always take a longer time to reach the products on the field (both mobile and network updates are normally required). According to a second embodiment of the invention, the flexibility of signaling changes is used for an advantage.Type: GrantFiled: May 13, 2005Date of Patent: May 5, 2009Assignee: Nokia CorporationInventors: Sari Nielsen, Harri Jokinen

Publication number: 20080280604Abstract: Mobility in E-UTRAN might not rely on neighbor cell list. In such a case, the user equipment (UE) may be responsible for finding cells and reporting to the network. Consequently signaling load may be increased and also handover (HO) performance can be degraded for the cases in which the target cell proposed by the UE is not good. Certain embodiments of the present invention give the operator some control of the signaling load and HO performance by providing a list of forbidden cells with regard to which the UE does not have to search and report.Type: ApplicationFiled: December 28, 2007Publication date: November 13, 2008Inventors: Ivan Ore, Lars Dalsgaard, Jarkko T.

Apparatus, method and computer program product providing priority setting for multi-rat interworking
Publication number: 20080268843Abstract: Apparatus, methods and computer program products operate an electronic device to receive through from a wireless communications network a prioritized list of radio access technologies; to store the prioritized list of radio access technologies in a memory of the electronic device; and to consult the prioritized list of radio access technologies during cell selection and reselection operations. In variants the radio access technologies listed in the prioritized list of radio access technologies can be E-UTRAN, UTRAN or GERAN. In a further variant to consult the prioritized list may mean to compare at least one of a signal measurement and a quality measurement with at least one threshold established for a certain radio access technology appearing in the prioritized list, and to select/reselect to the certain radio access technology only if the at least one of the signal measurement and the quality measurement exceeds the threshold.Type: ApplicationFiled: February 12, 2008Publication date: October 30, 2008Inventors: Ivan Ore, Sari Nielsen, Jarkko T.

Publication number: 20080253332Abstract: A method, apparatus and computer program product are provided that improve mobility procedures between base stations based on rules configurable by the operator that govern both the mobile terminal and the base stations. A method is provided in which a mobile terminal obtains system information from a neighboring base station. The system information is stored at the mobile terminal such that the mobile terminal may thereafter participate in a handover or reselection to a respective neighboring base station at least partially based upon the stored system information, typically without further verification of the system information. If desired, the mobile terminal can further determine if one or more predefined validity criterion is met with respect to the stored system information. If the predefined validity criterion is not met, the mobile terminal can then obtain system information, e.g., updated system information, from the neighboring base station.Type: ApplicationFiled: March 21, 2008Publication date: October 16, 2008Inventors: Ivan Ore, Lars Dalsgaard, Sari Nielsen, Jarkko T.

Patent number: 7356313Abstract: The use of the STTD is enabled in a network so that the common channels (CPICH etc.) do not need to be transmitted using transmit diversity, but the STTD can be enabled only for channels having dedicated pilots and which are intended for the UEs supporting this functionality. Other UEs not supporting transmit diversity can use the common channels as usual. In normal transmit diversity operation the UE will use the CPICH transmitted from both antennas as a phase reference. In the proposed method some of the common channels including CPICH are transmitted without transmit diversity even though the STTD is used on channels having dedicated pilots and which are intended for the UEs supporting this functionality.Type: GrantFiled: April 5, 2005Date of Patent: April 8, 2008Assignee: Spyder Navigations L.L.C.Inventors: Jorma Kaikkonen, Markku Kuusela, Sari Nielsen, Jussi Numminen
