Aspects are directed to a wireless measurement entity that performs a carrier phase measurement associated with a reference signal for positioning (RS-P) measurement for a position estimation of a user equipment (UE). The wireless measurement entity determines error information associated with the carrier phase measurement. The wireless measurement entity transmits the RS-P measurement to a position estimation entity, and further transmits the carrier phase measurement and an indication of the error information to the position estimation entity. The position estimation entity determines a position estimate of the UE based on the RS-P measurement, the carrier phase measurement, and the indication of the error information.

A station (STA) affiliated with a non-simultaneous-transmission-and-reception (NSTR) multi-link device (MLD) obtains a transmission opportunity (TXOP) on a first link of an NSTR link pair as a TXOP initiator while a medium synchronization delay timer of the STA is non-zero. STA determines that an intended TXOP responder has lost medium synchronization. The STA then transmits a control frame as an initial frame in the TXOP to the intended TXOP responder on the first link responsive to the determining.
