Abstract:
The present invention relates to a method and an arrangement for a mobile telecommunication network for selecting an antenna mode to be used for communication between a radio network and a mobile terminal operating in discontinuous reception mode. The arrangement comprises a determiner configured to determine a mode list comprising antenna modes both supported by the radio network and the mobile terminal, associating means configured to associate each antenna mode in the mode list with a degree of a pre-defined performance measure, retrieving means configured to retrieve information indicating the pre-defined performance measure for the mobile terminal, and a selector configured to select an antenna mode from the mode list at least based on the retrieved information.
Abstract:
A signalling method for reducing the bandwidth needed for communicating measurement values from at least a first source base station (11, 12, 13, 14) to at least a 5 first target base station (21, 22, 23, 24, 25) connected through a core base station (10) comprising the steps of—reporting at least a first measurement value from the at least first source base station (11, 12, 13, 14) to the core base station (10), —preferably sorting the measurement values in descending order, 10—including, in the core base station (10) value information about the at least first measurement value in a multicast message, —transmitting the multicast message to the at least first target base station (21, 22, 23, 24, 25), characterized in that the value information is determined as a first difference between a maximum value and the first measurement value.
Abstract:
The present invention relates to cellular mobile radio systems, and more especially it relates to multi-cell interference-limited environments, such as Orthogonal Frequency Division Multiple Access, OFDMA, and Code Division Multiple Access, CDMA, cellular mobile radio systems. Particularly, it relates to transmission power allocation in such systems. Method and systems where transmission power is based on parameters directly affecting perceived user performance parameters are disclosed.
Abstract:
The present invention relates to a user equipment (10) and a method for simultaneously receiving at least two services or transport channels, comprising: a receiver (11) having at least two receiver branches (11a, 11b), a reconfiguration arrangement (12) for dynamically reconfiguring said receiver by switching on or off at least one of said receiver branches for the reception of the said services, means (13) for measuring radio conditions. The reconfiguration arrangement is operatively arranged to execute said dynamic reconfiguration based on at least one of the measured radio conditions, network controlled quality of service targets of the said services and the measured quality of the said service. The equipment further comprising: means (14) for deriving the measured quality target from the network controlled quality of service for all simultaneously received services or transport channels, and means (15) using a largest derived measured quality target for dynamically reconfiguring said receiver.

Abstract:
In a cellular communication network, a user equipment can adapt the intensity (or measurement activity) with which it attempts to identify a new neighbour cell, based on a comparison of the quality of the already identified neighbour cells with the quality of a reference cell. This intensity is lower provided that the downlink received signal level (e.g. in terms of CPICH Ec/No or/and SCH Ec/No) from an appropriate selection of neighbour cells (cells belonging to active or candidate set) is not weaker than the reference (e.g. serving) cell by a certain threshold. On the other hand the UE shall identify a new cell with higher intensity provided the downlink received signal level (e.g. in terms of CPICH Ec/No or/and SCH Ec/No) from said selection of neighbour cells is weaker than the reference cell by a certain threshold.
