20110124360 | Methods and Arrangements in a Mobile Telecommunications Network - The present invention relates to method and arrangements for using an identifier of a predefined type, e.g. an RNTI identifying one configuration on an out-band control channel for activating the configuration identifiable by that identifier. The identifier is sent from the network to the UE, when a configuration corresponding to that identifier is to be activated. This implies that both the UE and the radio base station comprise a mapping between each configuration and the corresponding identity of each configuration. | 05-26-2011 |
20110170418 | Measurement Event Evaluation for Triggering Measurement Reports - Measurement event evaluation is of interest in a user equipment (UE) configured with multiple downlink component carriers (CCs). The UE performs measurements of a neighbor and a specific one of the configured CCs, being used as a reference CC. The UE evaluates, based on the measurements of the neighbor and the reference CC, being a specific one of the configured CCs, an evaluation criterion for triggering a measurement report from the UE. In this way, the number of event evaluations and measurement reports can be reduced, since a specific reference CC is used for the purpose of measurement event evaluation in a scenario when the UE is configured with multiple CCs. | 07-14-2011 |
20110212693 | Measurement Handling with Carrier Aggregation - Measurement handling is of interest in a user equipment (UE) in connected mode, with the UE being configured with multiple downlink component carriers (CCs). The UE evaluates the signal quality of a specific CC of the configured CCs against a configurable threshold to determine the need for neighbor cell measurements. The UE performs neighbor cell measurements if the signal quality of the specific CC is below the configurable threshold. In this way, robust and efficient measurement handling is provided, even though the UE is configured with multiple component carriers. | 09-01-2011 |
20110269462 | METHOD, APPARATUS AND SYSTEM FOR MOBILITY ENHANCEMENT IN DRX - When a user equipment (UE) is in a CONNECTED state with a base station of a wireless network and is also in a discontinuous reception (DRX) mode, a DRX parameter such as DRX period for the UE is compared with a threshold. If the DRX parameter is at or below the threshold, the UE applies a network controlled mobility mode with UE assist where the network controls handover of the UE to another cell. If the DRX parameter is above the threshold, the UE applies a UE controlled mobility mode in which the UE is free to select a best cell. In this way, DRX benefit of reduced power consumption is maintained while the time period in which the UE is unreachable is minimized. | 11-03-2011 |
