Determining a path loss for semi-persistent sounding reference signals for positioning

Abstract:

Techniques are provided for determining a path loss for semi-persistent SRS-for-positioning if the path loss resource set is not updatable through a MAC CE. An example method according to the disclosure includes receiving, from a serving base station, a medium access control control element, determining a spatial relation reference of a first sounding reference signal resource, setting a path loss reference for a sounding reference signal for positioning resource set to the spatial relation reference if the spatial relation reference is not an uplink reference signal, setting the path loss reference equal to a reference system resource from a synchronization signal block the user equipment utilizes to obtain a master information block if the spatial relation reference is an uplink reference signal, and transmitting the resources of the sounding reference signal for positioning resource set based at least in part on the path loss reference.
