Title:
RANDOM ACCESS MESSAGE DIFFERENTIATION
Document Type and Number:
WIPO Patent Application WO/2021/088785
Kind Code:
A1
Abstract:
Methods, systems, and devices for wireless communications are described to differentiate random access response types, such that a user equipment (UE) may identify a random access response for the UE. A UE may transmit a random access message that may be associated with a first type of random access response. The base station may be configured to communicate different types of random access responses, and may configure a random access response and an associated downlink control signal to correspond to the first type of random access response. The base station may transmit the downlink control signal to the UE by configuring different demodulation reference signals, different group identifiers, different search spaces or control resource sets, or different downlink control information. The UE may determine that the random access response is of the first type and may receive the random access response based on the decoded downlink control signal.
