Abstract

Official abstract text for this publication.

Embodiments of apparatus and methods for signaling for resource allocation and scheduling in 5G-NR integrated access and backhaul are generally described herein. In some embodiments, User Equipment configured for reporting a channel quality indicator (CQI) index in a channel state information (CSI) reference resource assumes a physical resource block (PRB) bundling size of two PRBs to derive the CQI index.

First claim

Opening claim text (preview).

What is claimed is: 1. An apparatus comprising: a processor, where the processor is configured to cause a user equipment (UE) to: configure the UE for reporting channel state information (CSI) including a channel quality indicator (CQI) information; process a CSI reference resource received from a next generation Node B (gNB); perform a CQI calculation, wherein to perform the CQI calculation, the processor is configured to assume a physical resource block (PRB) bundling size of two PRBs in the CSI reference resource; generate a report to report the CQI information based on the CQI calculation; and generate signalling to transmit the report to the gNB. 2. The apparatus of claim 1 , wherein the processor is further configured to assume the PRB bundling size in the CSI reference resource to derive a precoding matrix indicator (PMI) and a rank indicator (RI) for reporting in the report. 3. The apparatus of claim 2 , wherein the processor is further configured to decode radio-resource control (RRC) signaling and configure the UE for CSI reporting and reporting the CQI information. 4. The apparatus of claim 3 , wherein the processor is configured to: calculate the CQI for one or more CSI subbands based on an RRC configuration signalled by the gNB, and use a predetermined number of contiguous PRBs for estimating channel measurements of a physical downlink shared channel (PDSCH) corresponding to the PRB bundling size to calculate a channel estimation error and generate the CQI. 5. The apparatus of claim 4 , wherein the processor is configured to decode the RRC signalling to determine a CSI subband size for calculation of the CQI. 6. The apparatus of claim 1 , wherein the processor is further configured to derive a CQI index for each CQI value to be reported. 7. The apparatus of claim 1 , wherein the report is generated to further include a rank indicator (RI), a precoding matrix indicator (PMI), and layer indicator (LI). 8. The apparatus of claim 1 , wherein the processor comprises a baseband processor. 9. A non-transitory computer-readable storage medium that stores instructions for execution by a processor of a user equipment (UE) to configure the UE for reporting channel state information (CSI) including a channel quality indicator (CQI) information, wherein the instructions are executable by the processor to: process a CSI reference resource received from a next generation Node B (gNB); perform a CQI calculation, wherein to perform the CQI calculation, the processor is configured to assume a physical resource block (PRB) bundling size of two PRBs in the CSI reference resource; generate a report to report the CQI information based on the CQI calculation; and encode the report for transmission to the gNB. 10. The computer-readable storage medium of claim 9 , wherein the instructions are further executable to assume the PRB bundling size in the CSI reference resource to derive a precoding matrix indicator (PMI) and a rank indicator (RI) for reporting in the report. 11. The computer-readable storage medium of claim 10 , wherein the instructions are further executable to decode radio-resource control (RRC) signaling and configure the UE for CSI reporting and reporting the CQI information. 12. The computer-readable storage medium of claim 11 , wherein the instructions are further executable to: calculate the CQI for one or more CSI subbands based on an RRC configuration signalled by the gNB, and use a predetermined number of contiguous PRBs for estimating channel measurements of a physical downlink shared channel (PDSCH) corresponding to the PRB bundling size to calculate a channel estimation error and generate the CQI. 13. The computer-readable storage medium of claim 12 , wherein the instructions are further executable to decode the RRC signalling to determine a CSI subband size for calculation of the CQI. 14. The computer-readable storage medium of claim 9 , wherein the instructions are further executable to derive a CQI index for each CQI value to be reported. 15. The computer-readable storage medium of claim 9 , wherein the report is generated to further include a rank indicator (RI), a precoding matrix indicator (PMI), and layer indicator (LI). 16. A user equipment (UE), the comprising: wireless communication circuitry; and one or more processors coupled to the wireless communication circuitry, wherein the one or more processors are configured to cause the UE to: process a CSI reference resource received from a base station; perform a CQI calculation, wherein deriving the CQI calculation includes assuming a physical resource block (PRB) bundling size of two PRBs in the CSI reference resource; generate a report to report the CQI information based on the CQI calculation; and encoding the report for transmission to the base station. 17. The UE of claim 16 , wherein the one or more processors are further configured to assume the PRB bundling size in the CSI reference resource to derive a precoding matrix indicator (PMI) and a rank indicator (RI) for reporting in the report. 18. The UE of claim 16 , wherein the one or more processors are further configured to derive a CQI index for each CQI value to be reported. 19. The UE of claim 16 , wherein the one or more processors are further configured to: decode radio-resource control (RRC) signaling and configure the UE for CSI reporting and reporting the CQI calculation; calculate the CQI for one or more CSI subbands based on an RRC configuration signalled by the base station; and use a predetermined number of contiguous PRBs for estimating channel measurements of a physical downlink shared channel (PDSCH) corresponding to the PRB bundling size to calculate a channel estimation error and generate the CQI. 20. The UE of claim 19 , wherein the one or more processors are further configured to decode the RRC signalling to determine a CSI subband size for calculation of the CQI.
