Resource attribute configuration
Apparatuses, methods, and systems are disclosed for resource attribute configuration. One method includes receiving a first configuration for a resource. The first configuration includes a first parameter indicating a time-domain attribute associated with the resource, and the time-domain attribute is hard, soft, and/or unavailable. The method includes receiving a second configuration for the resource. The second configuration includes a second parameter indicating a frequency-domain attribute associated with the resource, and the frequency-domain attribute is hard, soft, and/or unavailable. The method includes determining an attribute for the resource based on the time-domain attribute and the frequency-domain attribute. The attribute is hard, soft, and/or unavailable. The method includes, in response to determining that the attribute is soft: determining whether the resource is indicated as available; and performing an operation on the resource.
1. An apparatus for wireless communication, the apparatus comprising an integrated access and backhaul (IAB) node, the apparatus further comprising:
a processor; and
a memory coupled to the processor, the processor configured to cause the apparatus to:
receive a first configuration associated with a symbol, wherein the first configuration comprises a first indication of whether the symbol is hard, soft, or unavailable;
receive a second configuration associated with a set of resource blocks (RBs) on the symbol, wherein the second configuration comprises a second indication of whether the set of RBs is hard, soft, or unavailable; and
determine, for an IAB distributed unit (IAB-DU) of the IAB node, whether to perform a communication on the set of RBs in the symbol based at least in part on the first indication and the second indication.
2. The apparatus of claim 1 , wherein the processor configured to further cause the apparatus to:
receive a control message comprising a third indication that indicates available or unavailable; and
determine, for the IAB-DU, whether to perform the communication on the set of RBs in the symbol further based on the third indication.
3. The apparatus of claim 2 , wherein the IAB-DU is determined to perform the communication on the set of RBs in the symbol in response to:
the first indication indicating that the symbol is soft;
the second indication indicating that the set of RBs is soft; and
the third indication indicating available.
4. The apparatus of claim 2 , wherein the IAB-DU is determined not to perform the communication on the set of RBs in the symbol in response to:
the first indication indicating that the symbol is soft;
the second indication indicating that the set of RBs is soft; and
the third indication indicating unavailable.
5. The apparatus of claim 2 , wherein the control message comprises a bitmap field associated with a plurality of sets of RBs, the plurality of sets of RBs includes the set of RBs, and a bit in the bitmap field indicates whether the set of RBs is available.
6. The apparatus of claim 2 , wherein the control message comprises an availability indication downlink control information (DCI) message from a parent node of the IAB node.
7. The apparatus of claim 1 , wherein the communication is a transmission, a reception, or a combination thereof.
8. The apparatus of claim 1 , wherein the first configuration is a time-domain configuration.
9. The apparatus of claim 1 , wherein the second configuration is a frequency-domain configuration.
10. A method at an integrated access and backhaul (IAB) node, the method comprising:
receiving a first configuration associated with a symbol, wherein the first configuration comprises a first indication of whether the symbol is hard, soft, or unavailable;
receiving a second configuration associated with a set of resource blocks (RBs) on the symbol, wherein the second configuration comprises a second indication of whether the set of RBs is hard, soft, or unavailable; and
determining, for an IAB distributed unit (IAB-DU) of the IAB node, whether to perform a communication on the set of RBs in the symbol based at least in part on the first indication and the second indication.
11. The method of claim 10 , further comprising:
receiving a control message comprising a third indication that indicates available or unavailable; and
determining, for the IAB-DU, whether to perform the communication on the set of RBs in the symbol further based on the third indication.
12. The method of claim 11 , wherein the IAB-DU is determined to perform the communication on the set of RBs in the symbol in response to:
the first indication indicating that the symbol is soft;
the second indication indicating that the set of RBs is soft; and
the third indication indicating available.
13. The method of claim 11 , wherein the IAB-DU is determined not to perform the communication on the set of RBs in the symbol in response to:
the first indication indicating that the symbol is soft;
the second indication indicating that the set of RBs is soft; and
the third indication indicating unavailable.
14. The method of claim 11 , wherein the control message comprises a bitmap field associated with a plurality of sets of RBs, the plurality of sets of RBs includes the set of RBs, and a bit in the bitmap field indicates whether the set of RBs is available.
15. The method of claim 10 , wherein the communication is a transmission, a reception, or a combination thereof.
16. The method of claim 10 , wherein the first configuration is a time-domain configuration.
17. The method of claim 10 , wherein the second configuration is a frequency-domain configuration.
18. An apparatus for wireless communication, the apparatus comprising an integrated access and backhaul (IAB) node, the apparatus further comprising:
a processor; and
a memory coupled with the processor, the processor configured to cause the apparatus to:
receive a time-domain configuration associated with a symbol, wherein the time-domain configuration comprises a first indication of whether the symbol is hard, soft, or unavailable;
receive a frequency-domain configuration associated with a set of resource blocks (RBs) on the symbol, wherein the frequency-domain configuration comprises a second indication of whether the set of RBs is hard, soft, or unavailable;
receive a control message comprising a third indication that indicates available or unavailable; and
determine, for an IAB distributed unit (IAB-DU) of the IAB node, whether to perform a transmission, a reception, or a combination thereof on the set of RBs in the symbol based on the first indication, the second indication, and the third indication.
19. The apparatus of claim 18 , wherein the IAB-DU is determined to perform the transmission, the reception, or the combination thereof on the set of RBs in the symbol in response to:
the first indication indicating that the symbol is soft;
the second indication indicating that the set of RBs is soft; and
the third indication indicating available.
20. The apparatus of claim 18 , wherein the IAB-DU is determined not to perform the transmission, the reception, or the combination thereof on the set of RBs in the symbol in response to:
the first indication indicating that the symbol is soft;
the second indication indicating that the set of RBs is soft; and
the third indication indicating unavailable.
