Abstract

Methods, systems, and devices for wireless communication are described. Some wireless communications network may operate in accordance with an open-RAN (ORAN) network specification which may support functional splitting between the ORAN distributed unit (O-DU) and the ORAN radio unit (RU). The O-DU may communicate with the O-RU using control messaging. The control message may include a resource resource element (RE) mask and a resource symbol mask, the resource RE mask indicating frequency resources to be allocated for a reference signal transmission across a set of antenna ports and the resource symbol mask indicating time resources to be allocated for the reference signal transmission. Additionally or alternatively, the O-DU may transmit a control message including a puncturing resource RE mask indicating frequency resources for applying a puncturing pattern and a symbol mask indicating time resources for applying the puncturing pattern during a transmission.

First claim

What is claimed is:

1. An apparatus for wireless communication, the apparatus comprising:
one or more processors; and
one or more memories coupled with the one or more processors, wherein the one or more processors are configured to:
receive a control message that includes a puncturing resource resource element (RE) mask and a symbol mask, wherein the puncturing resource RE mask indicates one or more frequency resources for application of a puncturing pattern, and wherein the symbol mask indicates one or more time resources for application of the puncturing pattern during a transmission; and
perform the transmission in accordance with the puncturing pattern indicated in the control message.

2. The apparatus of claim 1 , wherein the control message includes a field in a section header of the control message that indicates a number of puncturing patterns.

3. The apparatus of claim 1 , wherein the control message includes a resource block group inclusion flag indicative of whether the control message indicates a resource block group size and a resource block group mask.

4. The apparatus of claim 3 , wherein the control message indicates the resource block group size and the resource block group mask in a set of octets based at least in part on a value of the resource block group inclusion flag.

5. The apparatus of claim 3 , wherein the control message does not indicate the resource block group size and the resource block group mask in a set of octets based at least in part on a value of the resource block group inclusion flag.

6. The apparatus of claim 1 , wherein the control message includes a resource block group inclusion flag having a binary value of zero or one, wherein the binary value of zero indicates that the control message indicates a resource block group size and a resource block group mask in a set of octets, and wherein the binary value of one indicates that the control message does not indicates the resource block group size and the resource block group mask in the set of octets.

7. The apparatus of claim 1 , wherein the one or more processors are configured to:
determine, based at least in part on the control message, that the puncturing pattern applies to a first portion of the transmission and does not apply to a second portion of the transmission, wherein the first portion of the transmission is low priority and the second portion of the transmission is high priority.

8. The apparatus of claim 7 , wherein the first portion of the transmission comprises a physical downlink shared channel transmission and the second portion of the transmission comprises at least one of: a channel state information reference signal transmission, a synchronization signal block transmission, a physical downlink control channel transmission, a control resource set demodulation reference signal transmission, a positioning reference signal transmission, or a combination thereof.

9. The apparatus of claim 1 , wherein the apparatus is an open radio access network (O-RAN) radio unit, and wherein, to receive the control message, the one or more processors are configured to receive the control message from an O-RAN distributed unit.

10. A method of wireless communication performed by an apparatus, the method comprising:
receiving a control message that includes a puncturing resource resource element (RE) mask and a symbol mask, wherein the puncturing resource RE mask indicates one or more frequency resources for application of a puncturing pattern and wherein the symbol mask indicates one or more time resources for application of the puncturing pattern during a transmission; and
performing the transmission in accordance with the puncturing pattern indicated in the control message.

11. The method of claim 10 , the control message includes a field in a section header of the control message that indicates a number of puncturing patterns.

12. The method of claim 10 , wherein the control message includes a resource block group inclusion flag indicative of whether the control message indicates a resource block group size and a resource block group mask.

13. The method of claim 12 , the control message indicates the resource block group size and the resource block group mask in a set of octets based at least in part on a value of the resource block group inclusion flag.

14. The method of claim 12 , wherein the control message does not indicate the resource block group size and the resource block group mask in a set of octets based at least in part on a value of the resource block group inclusion flag.

15. The method of claim 10 , wherein the control message includes a resource block group inclusion flag having a binary value of zero or one, wherein the binary value of zero indicates that the control message indicates a resource block group size and a resource block group mask in a set of octets, and wherein the binary value of one indicates that the control message does not indicates the resource block group size and the resource block group mask in the set of octets.

16. The method of claim 10 , further comprising:
determining, based at least in part on the control message, that the puncturing pattern applies to a first portion of the transmission and does not apply to a second portion of the transmission, wherein the first portion of the transmission is low priority and the second portion of the transmission is high priority.

17. The method of claim 16 , wherein the first portion of the transmission comprises a physical downlink shared channel transmission and the second portion of the transmission comprises at least one of: a channel state information reference signal transmission, a synchronization signal block transmission, a physical downlink control channel transmission, a control resource set demodulation reference signal transmission, a positioning reference signal transmission, or a combination thereof.

18. The method of claim 10 , wherein the apparatus is an open radio access network (O-RAN) radio unit, and wherein the control message is received from an O-RAN distributed unit.

19. A non-transitory computer-readable medium having code stored thereon that, when executed by an apparatus, causes the apparatus to:
receive a control message that includes a puncturing resource resource element (RE) mask and a symbol mask, wherein the puncturing resource RE mask indicates one or more frequency resources for application of a puncturing pattern and wherein the symbol mask indicates one or more time resources for application of the puncturing pattern during a transmission; and
perform the transmission in accordance with the puncturing pattern indicated in the control message.

20. The non-transitory computer-readable medium of claim 19 , wherein the control message includes a field in a section header of the control message that indicates a number of puncturing patterns.

21. The non-transitory computer-readable medium of claim 19 , wherein the control message includes a resource block group inclusion flag indicative of whether the control message indicates a resource block group size and a resource block group mask.

22. An apparatus for wireless communication, the apparatus comprising:
one or more processors; and
one or more memories coupled with the one or more processors, wherein the one or more processors are configured to:
receive a control message that includes a puncturing resource resource element (RE) mask and a symbol mask, wherein the puncturing resource RE mask indicates one or more fr
