Abstract
According to an aspect, there is provided a method performed by a base station for adjusting a transmission power of a primary cell of a cell group. The method comprises receiving (302), from a wireless device, an indication of a first power headroom associated with the primary cell; determining (304) a power headroom target; comparing (306) the first power headroom and the power headroom target; and determining (308) whether to adjust a transmission power of the primary cell based on the comparison.
Claims22
A method performed by a base station for adjusting a transmission power of a primary cell of a cell group, the method comprising:
- receiving, from a wireless device, an indication of a first power headroom, PH_PSCell, associated with the primary cell;
- determining a power headroom target;
- comparing the first power headroom and the power headroom target;
- and
- determining whether to adjust a transmission power of the primary cell based on the comparison.

A base station configured for adjusting a transmission power of a primary cell of a cell group, the base station comprises a processor and a memory, said memory containing instructions executable by said processor whereby said base station is operative to:
- receive, from a wireless device, an indication of a first power headroom, PH_PSCell, associated with the primary cell;
- determine a power headroom target;
- compare the first power headroom and the power headroom target;
- and
- determine whether to adjust a transmission power of the primary cell based on the comparison.
