APPLICABLE TIME FOR MAC-CE BASED PATH LOSS REFERENCE SIGNAL (PL RS) UPDATE

Abstract:

Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for determining application timing for path loss reference signals (PL RS). For example, the application timing is determined by determining an applicable time for a medium access control control element (MAC-CE) based PL RS for physical uplink control channel (PUCCH) and other uplink transmissions. A user equipment (UE) may receive a MAC-CE indicating a PL RS update and determine the applicable time for applying the PL RS update based on one or more conditions. The applicable time may be a period after acknowledgement of the MAC-CE or correspond to a certain measurement sample of a new PL RS a period after acknowledgement of the MAC-CE. The one or more conditions may relate to a total configured number of PL RS for the UE, whether a MAC-CE based PL RS activation feature is enabled, among others.
