    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may indicate timing alignment factors in support of timing alignment adjustments by a base station or one or more transmission reception points (TRPs). Such timing adjustments may be in the context of cooperative beamforming and may relate to the timing with which the TRPs transmit respective instances of downlink transmissions to the UE. In some cases, the UE may report absolute timing alignment factors to support such timing alignment adjustments. Additionally or alternatively, the UE may report relative timing alignment factors, for example compared to signals received from a reference TRP, to support such timing alignment adjustments.

    Abstract: This disclosure provides systems, methods, and devices for wireless communication that support power headroom differential reporting for reference resource signals transmitted at different transmission power than other uplink transmissions. In a first aspect, a method of wireless communication includes determining a power headroom value, by a user equipment (UE), using a maximum configured transmission power and a transmission power configured for an uplink transmission at a configured modulation and coding scheme (MCS). The UE determines a reference resource signal power headroom value using the maximum configured transmission power and a reference resource signal transmission power configured for a reference resource signal transmission, calculates a reference resource power headroom differential between the power headroom value and the reference resource signal power headroom value, and transmits a report including the uplink transmission power headroom value and the reference resource power headroom differential. Other aspects and features are also claimed and described.
