Abstract

The disclosure relates to a pre 5th generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th generation (4G) communication system such as long term evolution (LTE). A method for operating a radio unit (RU) of a base station is provided. The method includes transmitting, to a digital unit (DU), a first message comprising a value indicating the maximum number of masks for one resource area, and receiving, from the DU, a second message generated based on the value, wherein the mask may indicate resources to which the same beam is applied within the resource area.

First claim

What is claimed is:

1. A method performed by a radio unit (RU) in a wireless communication system, the method comprising:
transmitting, to a digital unit (DU), a first message comprising a value indicating a maximum number of resource element (RE) mask for a section; and
receiving, from the DU, a second message generated based on the value,
wherein the maximum number of the RE mask for the section is a number of at least one pair of the RE mask and a section identifier (ID), and
wherein the RE mask indicates at least one RE associated with one beam within the section.

2. The method of claim 1 ,
wherein the first message further comprises at least one of a value indicating a maximum number of the section per symbol, or a value indicating a maximum number of the section per slot.

3. The method of claim 1 , wherein the maximum number of the RE mask is determined based on an available memory capacity of the RU.

4. The method of claim 1 , wherein the second message comprises a value indicating a number of RE mask equal to or less than the maximum number of the RE mask.

5. The method of claim 1 , wherein the first message is transmitted during a procedure in which the RU and the DU establish an initial connection.

6. The method of claim 1 , wherein the first message comprises a management (M)-plane message.

7. A method performed by a digital unit (DU) in a wireless communication system, the method comprising:
receiving, from a radio unit (RU), a first message comprising a value indicating a maximum number of resource element (RE) mask for a section; and
transmitting, to the RU, a second message generated based on the value,
wherein the maximum number of the RE mask for the section is a number of at least one pair of the RE mask and a section identifier (ID), and
wherein the RE mask indicates at least one RE associated with one beam within the section.

8. The method of claim 7 ,
wherein the first message further comprises at least one of a value indicating a maximum number of the section per symbol, or a value indicating a maximum number of the section per slot.

9. The method of claim 7 , wherein the maximum number of the RE mask is determined based on an available memory capacity of the RU.

10. The method of claim 7 , wherein the second message comprises a value indicating a number of RE mask equal to or less than the maximum number of the RE mask.

11. The method of claim 7 , wherein the first message is received during a procedure in which the RU and the DU establish an initial connection.

12. The method of claim 7 , wherein the first message comprises a management (M)-plane message.

13. The method of claim 7 , further comprising:
storing the value indicating the maximum number of the RE mask for the section.

14. A radio unit (RU) in a wireless communication system, the RU comprising:
a transceiver; and
a controller coupled with the transceiver,
and configured to:
transmit, to a digital unit (DU), a first message comprising a value indicating a maximum number of resource element (RE) mask for a section, and
receive, from the DU, a second message generated based on the value,

wherein the maximum number of the RE mask for the section is a number of at least one pair of the RE mask and a section identifier (ID), and
wherein the RE mask indicates at least one RE associated with one beam within the section.

15. The method of claim 1 , further comprising:
storing at least one value of the RE mask included in the second message in unit of time.

16. The method of claim 1 , wherein the second message comprises a control (C)-plane message, and includes a section extension information.

17. The method of claim 16 , wherein the section extension information includes information indicating the RE mask, and is associated with one of a section type 0, a section type 1, or a section type 3.

18. The method of claim 7 , wherein the second message comprises a control (C)-plane message, and includes a section extension information.

19. The method of claim 18 , wherein the section extension information includes information indicating the RE mask, and is associated with one of a section type 0, a section type 1, or a section type 3.

20. A digital unit (DU) in a wireless communication system, the DU comprising:
a transceiver; and
a controller coupled with the transceiver, and configured to:
receive, from a radio unit (RU), a first message comprising a value indicating a maximum number of resource element (RE) mask for a section, and
transmit, to the RU, a second message generated based on the value,

wherein the maximum number of the RE mask for the section is a number of at least one pair of the RE mask and a section identifier (ID), and
wherein the RE mask indicates at least one RE associated with one beam within the section.
