Abstract

A system and method for monitoring and scheduling. In some embodiments, the method includes receiving, by a user equipment (UE), a downlink control information (DCI), the DCI specifying the scheduling of a first Physical Downlink Shared Channel (PDSCH) and a second PDSCH.

Claims (62)

1. A method, comprising:

receiving, by a user equipment (UE), a downlink control information (DCI),

wherein the DCI specifies scheduling of a first Physical Downlink Shared Channel (PDSCH) and a second PDSCH,

wherein:

the DCI identifies a first row of a time domain resource allocation TDRA table;

the first row of the TDRA table specifies the scheduling of a first number of PDSCHs; and

a second row of the TDRA table specifies the scheduling of a second number of PDSCHs, different from the first number.

2. The method of claim 1 , wherein the DCI does not contain a code block group (CBG) field.

3. The method of claim 1 , further comprising:

receiving, by the UE, an indication that a third PDSCH will not be transmitted;

receiving the first PDSCH;

receiving the second PDSCH; and

not receiving the third PDSCH.

4. The method of claim 1 , wherein the DCI comprises a timing offset, and

the method further comprises transmitting an ACK or a NACK in a Physical Uplink Control Channel (PUCCH) slot, the PUCCH slot following a latest scheduled PDSCH by the timing offset.

5. The method of claim 1 , wherein the DCI comprises a downlink assignment index (DAI), the DAI having a value greater, by more than one, than a DAI in a most recent previously received DCI,

wherein a difference between the DAI and the DAI in the most recent previously received DCI equals a number of start and length indicators (SLIVs) in one of the first row or the second row of the TDRA table identified by the DCI.

6. The method of claim 1 , further comprising transmitting, by the UE, in a PUCCH, a maximum number of bits over each active serving cell configured to the UE, of a product of:

a maximum number of code block groups (CBGs) per PDSCH over the active serving cell, and

a maximum number of start and length indicators (SLIVs) in any row of the TDRA table for the active serving cell,

wherein the DCI comprises a downlink assignment index (DAI), the DAI having a value greater, by one, than a DAI in a previous DCI.

7. The method of claim 1 , wherein the DCI comprises a first downlink assignment index (DAI) corresponding to the first PDSCH and a second DAI corresponding to the second PDSCH.

8. The method of claim 1 , further comprising:

reporting, by the UE, a capability to perform processing of non-overlapping control channel elements (CCEs) within a first limit and processing of Physical Downlink Control Channels (PDCCHs) within a second limit over a number of consecutive slots, the first limit being P non-overlapping CCEs, the second limit being Q PDCCHs, and the number of consecutive slots being N, P, Q, and N being positive integers;

processing, by the UE, P CCEs received within M slots, M being less than or equal to N; and

processing, by the UE, Q PDCCHs received within the M slots,

P being greater than a corresponding standard-specified per-slot limit,

P being less than or equal to a product of N and the corresponding standard-specified per-slot limit,

Q being greater than a corresponding standard-specified per-slot limit, and

Q being less than or equal to the product of N and the corresponding standard-specified per-slot limit.

9. The method of claim 8 , further comprising:

reporting, by the UE, as a capability, a value of P and

reporting, by the UE, as a capability, a value of Q.

10. The method of claim 8 , further comprising reporting, by the UE, as a capability, a value of N.

11. The method of claim 8 , further comprising receiving the P CCEs in resource elements having a subcarrier spacing of 480 kHz or more.

12. The method of claim 8 , wherein the processing, by the UE, of the P CCEs comprises processing no CCEs received within N−N 0 slots, N 0 being a positive integer.

13. The method of claim 8 , further comprising sending, by the UE, an ACK, the ACK following a last symbol of a corresponding Physical Downlink Shared Channel (PDSCH) by a processing time greater than a corresponding standard-specified processing time for non-aggregated BD/CCE limits.

14. The method of claim 8 , further comprising sending, by the UE, a PUSCH, the PUSCH following a last symbol of a corresponding PDCCH by a preparation time greater than a corresponding standard-specified preparation time for non-aggregated BD/CCE limits.

15. The method of claim 8 , wherein a particular PDCCH of the Q PDCCHs schedules a Physical Downlink Shared Channel (PDSCH), the method further comprising receiving, by the UE, the PDSCH, the PDSCH beginning d symbols after the particular PDCCH, d being a positive integer, d being a standard-specified value or a value reported as a capability by the UE.

16. A system comprising:

a user equipment (UE), the UE comprising:

a radio; and

a processing circuit,

the processing circuit being configured to receive a downlink control information (DCI),

wherein the DCI specifies scheduling of a first Physical Downlink Shared Channel (PDSCH) and a second PDSCH,

wherein the DCI comprises a timing offset,

wherein the processing circuit is configured to transmit an ACK or a NACK in a Physical Uplink Control Channel (PUCCH) slot, the PUCCH slot following a latest scheduled PDSCH by the timing offset.

17. The system of claim 16 , wherein:

the DCI identifies a first row of a time domain resource allocation (TDRA) table;

the first row of the TDRA table specifies the scheduling of a first number of PDSCHs; and

a second row of the TDRA table specifies the scheduling of a second number of PDSCHs, different from the first number.

18. The system of claim 17 , wherein the DCI does not contain a code block group (CBG) field.

19. A system comprising:

a user equipment (UE), the UE comprising:

a radio; and

means for processing,

the means for processing being configured to receive a downlink control information (DCI),

wherein the DCI specifies a scheduling of a first Physical Downlink Shared Channel (PDSCH) and a second PDSCH,

wherein:

the DCI identifies a first row of a time domain resource allocation TDRA table:

the first row of the TDRA table specifies the scheduling of a first number of PDSCHs; and

a second row of the TDRA table specifies the scheduling of a second number of PDSCHs, different from the first number.
