Time resource assignment signaling mechanism for MSG3 transmission
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.
1. A method of operating a network node in a communication network for configuring a Msg3 transmission by a user equipment, UE, of the communication network, the method comprising:
generating an information message providing a transmission duration, a slot offset, a demodulation reference signal, DMRS, configuration, and a starting position for the Msg3 transmission by the UE, the slot offset being dependent on a subcarrier spacing; and
transmitting the information message to the UE for configuring the Msg3 transmission by the UE.
2. The method of claim 1 , wherein the information message comprises an indication of an entry in a time domain assignment table.
3. The method of claim 1 , wherein the information message is comprised in a Random Access Response Uplink grant.
4. The method of claim 1 , wherein a scheduling offset is dependent on the subcarrier spacing.
5. The method of claim 2 , wherein the time domain assignment table is configured using radio resource control, RRC.
6. The method of claim 5 , wherein the RRC is provided using remaining minimum system information, RMSI.
7. The method of claim 1 , wherein a dependency of the subcarrier spacing is configured in system information and/or RRC.
8. A method of operating a user equipment, UE, for scheduling a Msg3 transmission by the UE, the method comprising:
receiving an information message from a network node providing a transmission duration, a slot offset, a demodulation reference signal, DMRS, configuration, and a starting position for the Msg3 transmission, the slot offset being dependent on a subcarrier spacing; and
transmitting the Msg3 transmission based on a schedule determined based on the information message.
9. The method of claim 8 , wherein the information message comprises an indication of an entry in a time domain assignment table.
10. The method of claim 8 , wherein the information message is comprised in a Random Access Response Uplink grant.
11. The method of claim 8 , wherein a scheduling offset is dependent on the subcarrier spacing.
12. The method of claim 9 , wherein the time domain assignment table is configured using radio resource control, RRC.
13. The method of claim 12 , wherein the RRC is provided using remaining minimum system information, RMSI.
14. The method of claim 8 , wherein a dependency of the subcarrier spacing is configured in system information and/or RRC.
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 cause the network node to perform operations comprising:
generating an information message providing a transmission duration, a slot offset, a demodulation reference signal, DMRS, configuration, and a starting position for the Msg3 transmission by the UE, the slot offset being is dependent on a subcarrier spacing; and
transmitting the information message to the UE for configuring the Msg3 transmission by the UE.
16. The network node of claim 15 , wherein the information message comprises an indication of an entry in a time domain assignment table.
17. The network node of claim 15 , wherein the information message is comprised in a Random Access Response Uplink grant.
18. The network node of claim 15 , wherein a scheduling offset is dependent on the subcarrier spacing.
19. The network node of claim 16 , wherein the time domain assignment table is configured using radio resource control, RRC.

21. The network node of claim 15 , wherein a dependency of the subcarrier spacing is configured in system information and/or RRC.
22. A user equipment, UE, comprising:
a network interface;
a processor connected to the network interface; and
a memory storing program code that is executed by the processor to cause the UE to perform operations comprising:
receiving an information message from a network node providing a transmission duration, a slot offset, a demodulation reference signal, DMRS, configuration, and a starting position for a Msg3 transmission, the slot offset being dependent on a subcarrier spacing; and
transmitting the Msg3 transmission based on a schedule determined based on the information message.
23. The UE of claim 22 , wherein the information message comprises an indication of an entry in a time domain assignment table.
