A Ai / INFORMATION 'e _ 1012 .1 POWER CONTROL FIG. 10 TX POWER TX POWER 11 CONTROL CONTROL 1-1 (57) : Various aspects of the disclosure relate to power control for independent links. For example, power control at a device ot may be based on transmissions on multiple links. In some aspects, the independent links may involve a first device (e.g., a user equip- = ment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For f .r1 example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., 0 ---- a TRP) via a second link. In some scenarios, power control for the first device may be based on power control commands received on GC multiple links. In some scenarios, a power control constraint may be met taking into account the transmission power on multiple links. 1-1 0 ei O [Continued on next page] WO 2018/038861 Al MIDEDIMOMOIDEIREIHNIOMBEIHIIIIIIIIE11111111 CA, CH, CL, CN, CO, CR, CU, CZ, DE, DJ, DK, DM, DO, DZ, EC, EE, EG, ES, FI, GB, GD, GE, GH, GM, GT, HN, HR, HU, ID, IL, IN, IR, IS, JO, JP, KE, KG, KH, KN, KP, KR, KW, KZ, LA, LC, LK, LR, LS, LU, LY, MA, MD, ME, MG, MK, MN, MW, MX, MY, MZ, NA, NG, NI, NO, NZ, OM, PA, PE, PG, PH, PL, PT, QA, RO, RS, RU, RW, SA, SC, SD, SE, SG, SK, SL, SM, ST, SV, SY, TH, TJ, TM, TN, TR, TT, TZ, UA, UG, US, UZ, VC, VN, ZA, ZM, ZW.
