Time resource assignment signaling mechanism for msg3 transmission

Abstract

A method of scheduling Msg3 configuration by a network node may be provided. Information may be generated indicating transmission duration, DMRS configuration, and/or starting position for Msg3 sending by a user equipment, UE. Transmission of signaling of the information to the UE may be initiated for scheduling Msg3 transmission by the UE. A method of scheduling by the UE includes receiving information from the network node indicating transmission duration, DMRS configuration, and/or starting position for Msg3 transmission. The UE transmits Msg3 based on a schedule determined based on the information.

What is claimed is: 
     
         1 . A method of scheduling Msg3 configuration by a network node, the method comprising:
 generating an information message indicating transmission duration, slot offset, demodulation reference signal, DMRS, configuration, and starting position for Msg3 sending by a user equipment, UE, wherein the slot offset is dependent on a subcarrier spacing; and   initiating transmission of signaling of the information message to the UE for scheduling Msg3 transmission by the UE.   
     
     
         2 . The method of  claim 1 , wherein the information message comprises an entry in a time domain assignment table.

         15 . A network node comprising:
 a network interface;   a processor connected to the network interface; and   a memory storing program code that is executed by the processor to perform operations comprising:
 generating an information message indicating transmission duration, offset, demodulation reference signal, DMRS, configuration, and starting position for Msg3 sending by a user equipment, UE, wherein the slot offset is dependent on the subcarrier spacing; and 
 initiating transmission of signaling of the information message to the UE for scheduling Msg3 transmission by the UE. 
   
     
     
         16 . The network node of  claim 15 , wherein the information message comprises an entry in a time domain assignment table.
