Problems solved by technology

Since it is difficult to know ahead of time what power offset will match the desired TA target, this will most likely lead to unwanted adjustments to the DPCCH SIR target and thus to an unwanted increase in interference or a too low DPCC HSIR target

Embodiment Construction

[0031] The present invention is defined as a method and device that can be implemented in the following embodiments.

[0032] figure 1 The sending node 110 communicating with the receiving node 120 in the cell 130 of the wireless communication system 100 is shown.

[0033] In some embodiments, the sending node 110 may be a user equipment, such as a mobile cellular wireless phone, a personal digital assistant (PDA), a laptop computer, a computer, or any similar device suitable for radio communication. The receiving node 120 may be a base station, a wireless communication station, a fixed station, a control station, a repeater, or a similar device used for radio communication or any other type of equipment capable of communicating wireless resources.

[0034] However, the situation may also be the opposite. For example, in some other embodiments, the sending node 110 may be a base station, a wireless communication station, a fixed station, a control station, a repeater, or a similar de...

Abstract

Methods and arrangements for generating adjustment commands in a node. The adjustment commands adjust the transmission power of radio signals. The radio signals are sent over at least a first channel and a second channel. The adjustment is performed by adjusting a gain factor. The gain factor is associated with the relation between a first transmission power level of a first channel and a second transmission power level of a second channel.

Description

Technical field [0001] The present invention relates to a method and device in a communication system, and in particular to a method and device for generating an adjustment command for adjusting the transmission power of a radio signal by adjusting a gain factor. Background technique [0002] In communication systems based on, for example, Code Division Multiple Access (CDMA), outer loop power control is used to meet the required quality of service goals. This outer loop power control can be implemented in the user equipment to meet the downlink quality target and can also be implemented in the base station to meet the uplink quality target. In a wireless communication network, the downlink is the transmission path from the base station to the user equipment, and the uplink is the transmission path from the user equipment to the base station. It is important that the outer loop power control can maintain the required quality of service regardless of changing wireless conditions ...
