II (57) : Uplink transmission power levels may be adjusted in response to changes in a directional beam used for wireless communications. A beam change may be identified, wherein the beam change includes a transition from a first transmission configuration based on a first beam direction of a cell to a second transmission configuration based on a second beam direction of the cell. A down- \" link (DL) message associated with the beam change may be received, where- ® _ I in the DL message comprises a transmission power indication. An uplink (UL) message may be transmitted at a power level based at least in part on the trans- 91 mission indication. power = = = = _425 Daa 440 4 1-1 44 0 Data © J r 11 C:r GC 11 IN 11 © r'l 11G. 4 900 C [Continued on next page] WO 2017/189140 Al MIDEDIMOMMIDIRMEMOMMEIHOEHOMMOVOIS Declarations under Rule 4.17: — as to applicant's entitlement to apply for and be granted a patent (Rule 4.17(H)) — as to the applicant's entitlement to claim the earlier application (Rule 4.17(iii)) priority of the Published: — with international search report (Art. 21(3))
