摘要:
A radio network system employing a method with dynamic adjustment of the power offset that provides a “per-UE”-NACK to ACK power offset calculation method instead of using a fixed offset for all users in the cell is disclosed. Also for each UE, the power offset can adjusted dynamically. The adjustment is based on the error event of NACK to ACK. When an error event of NACK to ACK happens, the offset is increased, otherwise the offset is decreased. Hence, the offset can be controlled for each User Equipment for the duration of a call starting from some standard configured value is calculated and used rather than a fixed offset.

A method may include determining whether a discrepancy exists between scheduling headroom computable by a first device and scheduling headroom computable by a second device, determining one or more load measurements that the second device bases its computation of the scheduling headroom if it is determined that the discrepancy exists, modifying the one or more load measurements, and calculating the scheduling headroom based on the modified one or more load measurements.

A method and an arrangement for obtaining efficient radio resource utilization in a communication network comprising a first communication network entity (10), a second communication network entity (15) connected to said first communication network over a communication interface and one or more user equipments (18) transmitting data to said second communication network entity (15) over a radio interface. The user equipments (18) perform the step of autonomously selecting a hybrid automatic retransmission request (HARQ) operating point in order to efficiently deliver transmitted data.

A method and a device relating to a scheduling mechanism in a base station in a WCDMA system are disclosed. The mechanism enables the base station to rapidly adapt to users momentary traffic demands and to interference variations, a dynamical adjustable margin is proposed in this invention. The adjustment is based on the RoT measurement in a cell. To fully use the resource in a cell, the RoT can be targeted to be as closer to the RoTmax as possible however without exceed the limit. The scheduler is preferably set to schedule as high a rate or as many users as possible to fill up the available RoT. The margin which is reserved for the neighboring cell load and external interference is decreased step by step as long as the RoT measurement is below a threshold under RoTmax. Whenever the RoT measurement exceeds the threshold, the margin is increased by one step.
摘要:
A load control method is described herein that enables a base station to broadcast three downlink signals including a busy indicator, a maximum resource indicator and a minimum resource indicator to a mobile terminal. In response to receiving the downlink signals, the mobile terminal limits the utilization of a resource (e.g., bit rate, transmission power, power offset) it uses to transmit data to the base station. The mobile terminal may also send an uplink signal including a resource request to the base station. The base station can use the resource request to change the downlink signals if needed. It is with the proper use of these uplink/downlink signals that the behavior of the base station can be automatically optimized to the load situation.

A radio resource management technique in a cellular telecommunication system is disclosed. The telecommunication system comprises at least one radio network controlling component and one or more base station components operable to implement an uplink scheduling scheme in relation to one or more user terminals. A method embodiment comprises the steps of receiving, by one of the base station components from the at least one radio network controlling component, at least one interference control parameter, of generating one or more scheduling grants taking into account the at least one interference control parameter, and of issuing the one or more scheduling grants to one or more user terminals.
