Method and arrangement for load sharing power control
First Claim
1. A method for uplink power control, performed in a mobile station served by a base station of a communications network comprising a plurality of base stations, the method comprising:
- determining whether a bandwidth scheduled to the mobile station is below a predefined minimum bandwidth, Mmin; and
in response to determining that the bandwidth is below the predefined minimum bandwidth Mmin, adjusting a power spectrum density of the mobile station.

Abstract
A method for uplink power control at a mobile station which is served by a base station of a communications network comprising a plurality of base stations is provided where the power spectrum density of the mobile station is adaptable based on the bandwidth scheduled to the mobile station. The suggested power spectrum adaptation is obtained by providing for a switch to an alternative power control mode which enables for transmit power boosting at the mobile station. The decision whether to apply the suggested power spectrum adaptation can be made at the base station which is serving the mobile station, or at a selected mobile station.

9. A method for performing uplink power control of a plurality of mobile stations served by a first base station of a mobile communications network comprising a plurality of base stations, the method comprising the following steps executed in the first base station:
-
recognizing that one or more predefined trigger criteria to apply an alternative power control mode is fulfilled; instructing at least one of the mobile stations to apply the alternative power control mode, wherein the alternative power control mode enables a mobile station to adapt a power spectrum density on the basis of a bandwidth scheduled to the mobile station. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
