Method and apparatus for determining UE capability based on number of processed channels
View Patent ↗An apparatus and method are provided for counting a number of uplink and/or downlink channels per slot for a UE capability in order to determine a maximum number of channels a UE is capable of processing per slot. A UE counts all PDSCHs or PUSCHs that the UE is scheduled or configured to receive or transmit, respectively, except for exception 1, exception 2, or exception 3, wherein a beginning of the symbol j is at least N_2 symbols after an end of the symbol i, the SPS PDSCH is not counted, and generates UE capability information based on the counted number of the PDSCH or PUSCH per slot.
1. A user equipment (UE), comprising:
a transmitter or receiver that transmits or receives physical uplink shared channels (PUSCHs) or physical downlink shared channels (PDSCHs); and
a processor configured to:
count all PDSCHs or PUSCHs that the UE is scheduled or configured to receive or transmit per slot, regardless of whether the UE dynamically drops, cancels, or skips decoding of a PDSCH or a PUSCH, except for a case in which a dynamic grant (DG) PDSCH or DG PUSCH is prioritized over a configured grant (CG) PDSCH or CG PUSCH, and
generate UE capability information based on the counted number of the PDSCH or PUSCH per slot.
2. The UE of claim 1 , wherein the processor is further configured to transmit the generated UE capability information to a serving base station.
3. The UE of claim 1 , wherein the processor is further configured to prioritize the DG PUSCH over the CG PUSCH.
4. The UE of claim 1 , wherein the processor is further configured to prioritize the DG PDSCH over a configured semi persistent scheduling (SPS)-PDSCH.
5. The UE of claim 1 , wherein the processor is further configured to count all the PDSCHs or PUSCHs that the UE is scheduled or configured to receive or transmit.
6. The UE of claim 1 , wherein the processor is further configured to count all the PDSCHs or PUSCHs that the UE is scheduled or configured to receive or transmit, except for channels that do not include a transport block (TB).
7. The UE of claim 1 , wherein the processor is further configured to receive, via the receiver, a physical downlink control channel (PDCCH) including downlink control information (DCI).
8. The UE of claim 7 , wherein the DCI schedules a DG-PUSCH that overlaps in time with a CG PUSCH starting in a symbol on a same serving cell.
9. The UE of claim 8 , wherein the symbol begins at least N_2 symbols after the PDCCH, and
wherein a value of N_2 is a number that provides the UE with enough time to cancel the CG PUSCH and prioritize the DG PUSCH.
10. A base station, comprising:
a transmitter or receiver that transmits or receives physical downlink shared channels (PDSCHs) or physical uplink shared channels (PUSCHs); and
a processor configured to:
count all PDSCHs or PUSCHs that a user equipment (UE) is scheduled or configured to receive or transmit per slot, regardless of whether the UE dynamically drops, cancels, or skips decoding of a PDSCH or a PUSCH, except for a case in which a dynamic grant (DG) PDSCH or DG PUSCH is prioritized over a configured grant (CG) PDSCH or CG PUSCH, and
generate UE capability information based on the counted number of the PDSCH or PUSCH per slot.
11. The base station of claim 10 , wherein the processor is further configured to allocate resources to the UE based on the generated UE capability information.
12. The base station of claim 10 , wherein the processor is further configured to prioritize the DG PUSCH over the CG PUSCH.
13. The base station of claim 10 , wherein the processor is further configured to prioritize the DG PDSCH over a configured semi persistent scheduling (SPS)-PDSCH.
14. The base station of claim 10 , wherein the processor is further configured to count all the PDSCHs or PUSCHs that the UE is scheduled or configured to receive or transmit.
15. The base station of claim 10 , wherein the processor is further configured to count all the PDSCHs or PUSCHs that the UE is scheduled or configured to receive or transmit, except for channels that do not include a transport block (TB).
16. The base station of claim 10 , wherein the processor is further configured to transmit, via the transmitter, a physical downlink control channel (PDCCH) including downlink control information (DCI).
17. The base station of claim 16 , wherein the DCI schedules a DG-PUSCH that overlaps in time with a CG PUSCH starting in a symbol on a same serving cell.
18. The base station of claim 17 , wherein the symbol begins at least N_2 symbols after the PDCCH, and
wherein a value of N_2 is a number that provides the UE with enough time to cancel the CG PUSCH and prioritize the DG PUSCH.
19. A method performed by a user equipment (UE), the method comprising:
counting all physical downlink shared channels (PDSCHs) or physical uplink shared channels (PUSCHs) that the UE is scheduled or configured to receive or transmit per slot, regardless of whether the UE dynamically drops, cancels, or skips decoding of a PDSCH or a PUSCH, except for a case in which a dynamic grant (DG) PDSCH or DG PUSCH is prioritized over a configured grant (CG) PDSCH or CG PUSCH; and
generating UE capability information based on the counted number of the PDSCH or PUSCH per slot.
20. The method of claim 19 , further comprising transmitting the generated UE capability information to a serving base station.
