Abstract

A system and method for signaling design and configuration are disclosed herein. In one embodiment, the system and method are configured to transmit, by a wireless communication node to a first wireless communication device, configuration information, wherein the first wireless communication device is a reduced capability user equipment device, and wherein the configuration information includes a Physical Random Access Channel configuration.

Claims (24)

1. A wireless communication method, comprising:

transmitting, by a wireless communication node to a first wireless communication device, configuration information,

wherein the first wireless communication device is a reduced capability user equipment (UE) device, and wherein the configuration information includes a Physical Random Access Channel (PRACH) configuration including a starting position of a PRACH transmission occasion allocated for the first wireless communication device in frequency domain, and wherein the starting position of the PRACH transmission occasion allocated for the first wireless communication device is indicated by a number of offset resource blocks away from a starting of an uplink initial bandwidth part allocated for at least one of the first wireless communication device or a second wireless communication device, wherein the starting of the uplink initial bandwidth part allocated for the first wireless communication device is adjacent to an ending position of the uplink initial bandwidth part allocated for the second wireless communication device.

2. The wireless communication method of claim 1 , wherein the number of offset resource blocks is away from the starting of the uplink initial bandwidth part allocated for the first wireless communication device.

3. The wireless communication method of claim 1 , wherein the number of offset resource blocks is away from the starting of the uplink initial bandwidth part allocated for the second wireless communication device.

4. The wireless communication method of claim 1 , wherein the PRACH configuration includes a number of PRACH transmission occasions allocated for the first wireless communication device in frequency domain, wherein the number of PRACH transmission occasions allocated includes one of: one PRACH transmission occasion, two PRACH transmission occasions or four PRACH transmission occasions.

5. The wireless communication method of claim 1 , wherein the PRACH configuration includes a number of PRACH transmission occasions in time domain.

6. The wireless communication method of claim 1 , wherein a PRACH preamble is transmitted in one or more PRACH transmission occasions.

7. The wireless communication method of claim 1 , wherein the PRACH configuration includes a relative PRACH configuration index, the relative PRACH configuration index indicating a PRACH time domain parameter corresponding to a PRACH preamble format, the PRACH preamble format configured for the second wireless communication device.

8. The wireless communication method of claim 1 , wherein the PRACH configuration includes an association pattern, wherein the association pattern maps one or more synchronization signal blocks (SSBs) to a PRACH transmission occasion during an association pattern period for the first wireless communication device.

9. A wireless communication node comprising:

at least one processor configured to:

transmit, via a transmitter to a first wireless communication device, configuration information,

wherein the first wireless communication device is a reduced capability user equipment (UE) device, and wherein the configuration information includes a Physical Random Access Channel (PRACH) configuration including a starting position of a PRACH transmission occasion allocated for the first wireless communication device in frequency domain, and wherein the starting position of the PRACH transmission occasion allocated for the first wireless communication device is indicated by a number of offset resource blocks away from a starting of an uplink initial bandwidth part allocated for at least one of the first wireless communication device or a second wireless communication device, wherein the starting of the uplink initial bandwidth part allocated for the first wireless communication device is adjacent to an ending position of the uplink initial bandwidth part allocated for the second wireless communication device.

10. The wireless communication node of claim 9 , wherein the number of offset resource blocks is away from the starting of the uplink initial bandwidth part allocated for the first wireless communication device.

11. The wireless communication node of claim 9 , wherein the number of offset resource blocks is away from the starting of the uplink initial bandwidth part allocated for the second wireless communication device.

12. The wireless communication node of claim 9 , wherein the PRACH configuration includes a number of PRACH transmission occasions allocated for the first wireless communication device in frequency domain, wherein the number of PRACH transmission occasions allocated includes one of: one PRACH transmission occasion, two PRACH transmission occasions or four PRACH transmission occasions.

13. The wireless communication node of claim 9 , wherein the PRACH configuration includes a number of PRACH transmission occasions in time domain.

14. The wireless communication node of claim 9 , wherein a PRACH preamble is transmitted in one or more PRACH transmission occasions.

15. The wireless communication node of claim 9 , wherein the PRACH configuration includes a relative PRACH configuration index, the relative PRACH configuration index indicating a PRACH time domain parameter corresponding to a PRACH preamble format, the PRACH preamble format configured for the second wireless communication device.

16. The wireless communication node of claim 9 , wherein the PRACH configuration includes an association pattern, wherein the association pattern maps one or more synchronization signal blocks (SSBs) to a PRACH transmission occasion during an association pattern period for the first wireless communication device.

17. A wireless communication method comprising:

receiving, by a first wireless communication device from a wireless communication node, configuration information, wherein the first wireless communication device is a reduced capability user equipment, UE, device, wherein the configuration information includes a Physical Random Access Channel, PRACH, configuration including a starting position of a PRACH transmission occasion allocated for the first wireless communication device in frequency domain, and wherein the starting position of the PRACH transmission occasion allocated for the first wireless communication device is indicated by a number of offset resource blocks away from a starting of an uplink initial bandwidth part allocated for at least one of the first wireless communication device or a second wireless communication device, wherein the starting of the uplink initial bandwidth part allocated for the first wireless communication device is adjacent to an ending position of the uplink initial bandwidth part allocated for the second wireless communication device.

18. The wireless communication method of claim 17 , wherein the PRACH configuration includes a number of PRACH transmission occasions allocated for the first wireless communication device in frequency domain, wherein the number of PRACH transmission occasions allocated includes one of: one PRACH transmission occasion, two PRACH transmission occasions or four PRACH transmission occasions.
