Abstract: Systems and methods for early indication for multiple features are provided. In some embodiments, a method performed by a wireless device for early indication of features includes: determining to use an on-demand Random Access (RA) resource; transmitting, to a network node, an activation preamble to activate the on-demand RA resource; and transmitting, to the network node, a preamble on the on-demand RA resource. Certain embodiments may provide one or more of the following technical advantages. The amount of RA resources can be made larger when there is demand for it. If no User Equipment (UE) is interested in using the on-demand RA resource, those radio resources can be used by the network for other purposes, e.g., dynamic scheduling of user data on Physical Uplink Shared Channel (PUSCH). The amount of RA resources hence scales with the demand without tying up and wasting resources when not used.
