Abstract: This invention extends routing mechanisms that use link metrics for route selection so that: A link metric cross correlation vector is determined for all links, where each element in the vector corresponds to some other link, and reflects the change in the link metric value if a data flow would already use this other link. The invention further describes a specific embodiment where all cross-correlating links are adjacent to each other, i.e., they terminate or originate in a common node. A mechanism is described to create an extended routing graph. This extended graph permits the use of standard polynomial time algorithms that simultaneously construct the optimal route and find the optimal route metric (such as shortest-path algorithms) also for the adjacent link cross-correlating case.

Abstract: The present invention relates to a method and a wireless station for initiating radio resource measurements. A wireless station identifies a need for radio resource measurements by a second wireless station despite there is no association between the wireless station and the second wireless station allowing direct radio communication between said stations. The wireless station initiates a request for radio resource measurements by the second wireless station.

Abstract: The present invention is based on the idea to allocate HS-DSCH power at TTI based on the HS-SCCH allocation of UI and an estimation of the HS-SCCH allocation of TTI+1. The estimation of the HS-SCCH allocation of TTI+1 is based on estimation of which users that will be scheduled at the time denoted TTI+1. i.e., the users that have a high probability to be selected for transmission by the scheduler at the time denoted TTI+1 are determined. That is performed by calculating for each user the probability that the user will be selected for transmission by the scheduler. The users that have a high probability to be scheduled at the time TTI+1 are included in a candidate set according to the present invention.

Abstract: A technique is provided for use by a Multi-Radio Management Resource (MRRM) component of a multi-radio wireless communication system for controlling the handover of a mobile terminal between different radio access technologies (RAT). In one example, all suitable RATs having coverage areas currently covering the location of a mobile terminal are identified. The performance gain that might be achieved via a handover to one of the other RATs is then determined by the MRRM based on various performance gain factors. Handover costs that will be incurred as a result of the handover are also explicitly calculated. Then, a cost-adjusted gain is determined by the MRRM based on the performance gain and the handover costs. A handover is only triggered by the MRRM if the cost-adjusted gain exceeds a minimum threshold. The speed and trajectory of the mobile terminal may also be considered.

Abstract: The invention discloses a mobile station (200), a base station (300), a method and a computer program for communication in a wireless communication network (100), where cell edge user experiencing difficulties on the contention-based channel are treated differently than those users who are not power limited and/or do not experience collisions.

Abstract: Information can be communicated back from a receiver to a transmitter over a serial link designed for communication to be essentially only in one direction without requiring a separate feedback path with an extra wire. This is achieved by changing at least one characteristic of the receiver input. For example, the receiver input impedance, the receiver input voltage, or both, may be altered. The change in a characteristic of the receiver input can be detected by an appropriately designed transmitter, and such detection can be used to trigger a change in the behavior of the transmitter. Advantageously, only simple alterations are required in conventional serial link circuits to provide a low bandwidth reverse communication path over the same wires. Such a change in a receiver input characteristic can also be employed to inform a transmitter of the existence of a receiver that is on a card that is hot-plugged into system.
