Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an activation command to activate multiple spatial relations for a single physical uplink control channel (PUCCH) resource. The UE may communicate in the single PUCCH resource using the multiple spatial relations. Numerous other aspects are provided.

A method is provided for performing power control by a first base station in a wireless communication system. The first base station acquires a parameter value related with signal strength of a second base station, determines an upper power limit of the first base station in consideration of the signal strength of the second base station and performs signal transmission in consideration of the upper power limit of the first base station. If a first condition including that the parameter value is equal to or more than a first threshold value is satisfied, the upper power limit of the first base station is an intermediate value. If a second condition including that the parameter value is less than the first threshold value is satisfied, the upper power limit of the first base station is a pre-determined value related with the transmit power of the first base station.
