Abstract

Presented are systems, methods, apparatuses, or computer-readable media for resource mapping of inter-cell multi transmission/reception points (TRPs) operation. A wireless communication device may determine at least one resource element that is scheduled for a defined communication associated with a first configuration index, and is assigned for use for at least one signal associated with a second configuration index. The wireless communication device may perform the defined communication using resource elements other than the determined at least one resource element.

Claims (38)

1. A method comprising:

determining, by a wireless communication device, that at least one resource element is not available based on (i) the at least one resource element being that is scheduled for a defined communication of a non-serving cell associated with a first configuration index, and (ii) the at least one resource element being assigned for use for at least one signal of the non-serving cell associated with a second configuration index that is same as the first configuration index, wherein the first configuration index comprises a first physical cell identity (PCI) index and the second configuration index comprises a second PCI index; and

performing, by the wireless communication device, the defined communication using resource elements other than the determined at least one resource element, wherein the at least one resource element is not available for the defined communication.

2. The method of claim 1 , wherein:

the defined communication comprises reception of a physical downlink shared channel (PDSCH), and

the at least one signal comprises a synchronization signal/physical broadcast channel (SS/PBCH) block (SSB).

3. The method of claim 2 , wherein the SSB is used as a quasi co-location (QCL) source corresponding to the PDSCH.

4. The method of claim 3 , wherein the SSB is indicated in a transmission configuration indicator (TCI) state of a TCI state list configured by radio resource control (RRC) signaling.

5. The method of claim 1 , wherein:

the defined communication comprises transmission of a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH), a preamble random access channel (PRACH), or a sounding reference signal (SRS), and

the at least one signal comprises a synchronization signal/physical broadcast channel (SS/PBCH) block (SSB).

6. The method of claim 1 , wherein:

the defined communication comprises reception of a physical downlink control channel (PDCCH), or a downlink positioning reference signal (DL-PRS), and

the at least one signal comprises a synchronization signal/physical broadcast channel (SS/PBCH) block (SSB).

7. A wireless communication device comprising:

at least one processor configured to:

determine that at least one resource element is not available based on (i) the at least one resource element being scheduled for a defined communication of a non-serving cell associated with a first configuration index, and (ii) the at least one resource element being assigned for use for at least one signal of the non-serving cell associated with a second configuration index that is same as the first configuration index, wherein the first configuration index comprises a first physical cell identity (PCI) index and the second configuration index comprises a second PCI index; and

perform the defined communication using resource elements other than the determined at least one resource element, wherein the at least one resource element is not available for the defined communication.

8. The wireless communication device of claim 7 , wherein:

the defined communication comprises reception of a physical downlink shared channel (PDSCH), and

the at least one signal comprises a synchronization signal/physical broadcast channel (SS/PBCH) block (SSB).

9. The wireless communication device of claim 8 , wherein the SSB is used as a quasi co-location (QCL) source corresponding to the PDSCH.

10. The wireless communication device of claim 9 , wherein the SSB is indicated in a transmission configuration indicator (TCI) state of a TCI state list configured by radio resource control (RRC) signaling.

11. The wireless communication device of claim 7 , wherein:

the defined communication comprises transmission of a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH), a preamble random access channel (PRACH), or a sounding reference signal (SRS), and the at least one signal comprises a synchronization signal/physical broadcast channel (SS/PBCH) block (SSB).

12. The wireless communication device of claim 7 , wherein:

the defined communication comprises reception of a physical downlink control channel (PDCCH), or a downlink positioning reference signal (DL-PRS), and

the at least one signal comprises a synchronization signal/physical broadcast channel (SS/PBCH) block (SSB).

13. A non-transitory computer readable medium storing instructions, which when executed by at least one processor, cause the at least one processor to:

determine that at least one resource element is not available based on (i) the at least one resource element being scheduled for a defined communication of a non-serving cell associated with a first configuration index, and 11 ) the at least one resource element being assigned for use for at least one signal of the non-serving cell associated with a second configuration index that is same as the first configuration index, wherein the first configuration index comprises a first physical cell identity (PCI) index and the second configuration index comprises a second PCI index; and

perform the defined communication using resource elements other than the determined at least one resource element, wherein the at least one resource element is not available for the defined communication.

14. The non-transitory computer readable medium of claim 13 , wherein:

the defined communication comprises reception of a physical downlink shared channel (PDSCH), and

the at least one signal comprises a synchronization signal/physical broadcast channel (SS/PBCH) block (SSB).

15. The non-transitory computer readable medium of claim 14 , wherein the SSB is used as a quasi co-location (QCL) source corresponding to the PDSCH.

16. The non-transitory computer readable medium of claim 15 , wherein the SSB is indicated in a transmission configuration indicator (TCI) state of a TCI state list configured by radio resource control (RRC) signaling.

17. The non-transitory computer readable medium of claim 13 , wherein:

the defined communication comprises transmission of a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH), a preamble random access channel (PRACH), or a sounding reference signal (SRS), and the at least one signal comprises a synchronization signal/physical broadcast channel (SS/PBCH) block (SSB).
