摘要：
The present disclosure is related to a UE, a network node, and methods for feature based preamble grouping. A method at a UE for performing a random access procedure with a network node comprises: receiving a configuration for PRACH transmission; determining a first preamble from two or more groups of preambles indicated by the received configuration at least partially based on the received configuration and one or more measurements at the UE, the first preamble indicating whether one or more features are requested or not; and transmitting, to the network node, the PRACH transmission by using the first preamble.
