Abstract
Downlink control information (DCI) size determination for multi-cell scheduling. A method includes receiving first information for a set of cells, identifying first combinations of cells from the set of cells, and determining a first maximum size among first sizes of a first DCI format. The first DCI format schedules physical downlink shared channel (PDSCH) receptions on a first combination of cells from the first combinations of cells, and the first sizes correspond to the first combinations of cells. The method further includes receiving the first DCI format based on the first maximum size.
Claims20
A method for a user equipment (UE), the method comprising:
- identifying a maximum number of sizes for downlink control information (DCI) that the UE can receive per slot and per cell;
- receiving first information for search space sets for reception of physical downlink control channels (PDCCHs), wherein the PDCCHs provide DCIs for a cell;
- receiving, in a first slot, first PDCCHs according to the search space sets, wherein the first PDCCHs provide first DCIs for the cell;
- receiving, in a second slot, second PDCCHs according to the search space sets, wherein the second PDCCHs provide second DCIs for the cell;
- determining a first number of sizes for the first DCIs;
- and
- determining a second number of sizes for the second DCIs, wherein:
- the first number of sizes does not exceed the maximum number of sizes, and
- the second number of sizes does not exceed the maximum number of sizes.
A user equipment (UE) comprising:
- a processor configured to identify a maximum number of sizes for downlink control information (DCI) that the UE can receive per slot and per cell;
- and
- a transceiver operably coupled with the processor, the transceiver configured to:
- receive first information for search space sets for reception of physical downlink control channels (PDCCHs), wherein the PDCCHs provide DCIs for a cell;
- receive, in a first slot, first PDCCHs according to the search space sets, wherein the first PDCCHs provide first DCIs for the cell;
- and
- receive, in a second slot, second PDCCHs according to the search space sets, wherein the second PDCCHs provide second DCIs for the cell,
- wherein the processor is further configured to:
- determine a first number of sizes for the first DCIs, and
- determine a second number of sizes for the second DCIs, and
- wherein:
- the first number of sizes does not exceed the maximum number of sizes, and
- the second number of sizes does not exceed the maximum number of sizes.
A base station comprising:
- a processor configured to identify a maximum number of sizes for downlink control information (DCI) that a user equipment (UE) can receive per slot and per cell;
- and
- a transceiver operably coupled with the processor, the transceiver configured to:
- transmit first information for search space sets for transmission of physical downlink control channels (PDCCHs), wherein the PDCCHs provide DCIs for a cell;
- transmit, in a first slot, first PDCCHs according to the search space sets, wherein the first PDCCHs provide first DCIs for the cell;
- transmit, in a second slot, second PDCCHs according to the search space sets, wherein the second PDCCHs provide second DCIs for the cell;
- wherein the processor is further configured to:
- determine a first number of sizes for the first DCIs, and
- determine a second number of sizes for the second DCIs, and
- wherein:
- the first number of sizes does not exceed the maximum number of sizes, and
- the second number of sizes does not exceed the maximum number of sizes.
