Stable power headroom reference for carrier aggregation

An apparatus for wireless communication at a network node, comprising:

• one or more memories;
• and
• one or more processors coupled with the one or more memories and configured to cause the network node to:
• transmit configuration information indicative of a carrier aggregation configuration associated with a first component carrier (CC) and a second CC;
• transmit scheduling information indicative of at least one scheduled transmission during a transmission occasion associated with at least one of the first CC or the second CC;
• and
• receive, using at least one transmission power during the transmission occasion, at least one communication on the at least one of the first CC or the second CC, the at least one transmission power comprising a first transmission power associated with the first CC, wherein the first transmission power is based at least in part on a first maximum transmission power limit associated with the first CC and a first power headroom (PHR) reference value associated with the first CC, and wherein the first PHR reference value is determined independently of the first maximum transmission power limit.

A method of wireless communication performed at a user equipment (UE), comprising:

• receiving configuration information indicative of a carrier aggregation configuration associated with a first component carrier (CC) and a second CC;
• receiving scheduling information indicative of at least one scheduled transmission during a transmission occasion associated with at least one of the first CC or the second CC;
• and
• transmitting, using at least one transmission power during the transmission occasion, at least one communication on the at least one of the first CC or the second CC, the at least one transmission power comprising a first transmission power associated with the first CC, wherein the first transmission power is based at least in part on a first maximum transmission power limit associated with the first CC and a first power headroom (PHR) reference value associated with the first CC, and wherein the first PHR reference value is determined independently of the first maximum transmission power limit.
