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 RE mask indicates at least one RE associated with one beam within the section.

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

3. 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 RE mask.

4. 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.

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

6. 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 DU, a second message generated based on the value,
wherein the RE mask indicates at least one RE associated with one beam within the section.

7. The method of claim 6 , wherein the maximum number of RE mask is determined based on an available memory capacity of the RU.

8. The method of claim 6 , wherein the second message comprises a value indicating a number of RE mask equal to or less than the maximum number of RE mask.

9. The method of claim 6 , wherein the first message is received during a procedure in which the RU and the DU establish an initial connection.

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

11. The method of claim 6 , further comprising:
storing for each beam a space comprising a section ID value and a mask.

12. The method of claim 7 , wherein, when a number of messages exceeding the available memory capacity available for the RU are received within a specific time unit, a portion of the messages are lost and a decoding of the messages fails.

13. The method of claim 6 , further comprising:
transmitting a control message without consideration of an available memory capacity of the RU based on failing to receive information indicating an amount of the available memory capacity of the RU.

14. A radio unit (RU) in a wireless communication system, the RU comprising:
a transceiver; and
at least one processor connected to the transceiver,
wherein the at least one processor, when executing instructions, is 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 RE mask indicates at least one RE associated with one beam within the section.

15. The RU of claim 14 , wherein the maximum number of masks is determined based on an available memory capacity of the RU.

16. The RU of claim 14 , wherein the second message comprises a value indicating a number of masks equal to or less than the maximum number of masks.

17. The RU of claim 14 , wherein the first message comprises a management (M)-plane message.
