Abstract

Harmonizing communication may be valuable in many communication systems. For example, third generation partnership project (3GPP) new radio (NR) may benefit from schemes, methods, systems, and the like for beam refinement and collision avoidance. A method can include receiving a message from an access point. The message from the access point can be configured to indicate an uplink grant by indicating a resource corresponding to the uplink grant or by indicating a sub-beam specific random access response. The method can also include transmitting a message to the access point. The message to the access point can be transmitted using resources of the uplink grant.
