Frequency domain resource allocation for single downlink control information-based multi-cell scheduling

A method of a user equipment (UE), comprising:

• receiving, from a network, configuration information defining a first plurality of resource block group (RBG) sizes with respect to a plurality of bandwidth part (BWP) sizes and numbers of scheduled cells;
• receiving, from the network, a downlink control information (DCI) that schedules communication between the UE and the network on one or more scheduled cells, the DCI comprising a one or more frequency domain resource allocation (FDRA) fields corresponding to the one or more scheduled cells and a first BWP index;
• identifying one or more BWP sizes corresponding to the one or more scheduled cells using the BWP index;
• identifying one or more RBG sizes corresponding to the one or more scheduled cells from the first plurality of RBG sizes by applying the one or more BWP sizes and a number of the one or more scheduled cells with the configuration information;
• identifying one or more frequency domain resources for the communication between the UE and the network on the one or more scheduled cells by applying one or more resource indicator values (RIVs) from the one or more FDRA fields with the one or more RBG sizes for the one or more scheduled cells;
• wherein a first RIV of the one or more RIVs from a first FDRA field of the one or more FDRA fields is applied with a first RBG size of the one or more RBG sizes for a first scheduled cell of the one or more scheduled cells that corresponds to the first FDRA field;
• and
• performing the communication with the network on the one or more scheduled cells.

A method of a user equipment (UE), comprising:

• receiving, from a network, configuration information comprising one or more scaling factors and defining a plurality of resource block group (RBG) sizes with respect to a plurality of bandwidth part (BWP) sizes;
• receiving, from the network, a downlink control information (DCI) that schedules communication between the UE and the network on one or more scheduled cells, the DCI comprising one or more frequency domain resource allocation (FDRA) fields corresponding to the one or more scheduled cells and a first BWP index;
• identifying one or more BWP sizes corresponding to the one or more scheduled cells using the BWP index;
• identifying one or more RBG sizes corresponding to the one or more scheduled cells from the plurality of RBG sizes by applying the one or more BWP sizes with the configuration information;
• selecting a first scaling factor from the one or more scaling factors;
• generating one or more scaled RBG sizes corresponding to the one or more scheduled cells by applying the first scaling factor to the one or more RBG sizes;
• identifying one or more frequency domain resources for the communication between the UE and the network on the one or more scheduled cells by applying one or more resource indicator values (RIVs) from the one or more FDRA fields with the one or more scaled RBG sizes for the one or more scheduled cells, wherein a first RIV of the one or more RIVs from a first FDRA field of the one or more FDRA fields is applied with a first scaled RBG size of the one or more scaled RBG sizes for a first scheduled cell of the one or more scheduled cells that corresponds to the first FDRA field;
• and
• performing the communication with the network on the one or more scheduled cells.

A method of a radio access network (RAN), comprising:

• sending, to a user equipment (UE), configuration information defining a first plurality of resource block group (RBG) sizes with respect to bandwidth part (BWP) sizes and numbers of scheduled cells;
• identifying one or more frequency domain resources for communication between the UE and the RAN on one or more scheduled cells according to one or more RBG sizes for one or more BWP sizes of the one or more scheduled cells and a number of the one or more scheduled cells;
• calculating one or more resource indicator values (RIVs) for the one or more frequency domain resources using the one or more RBG sizes, the one or more RIVs corresponding to the one or more scheduled cells;
• sending, to the UE, a downlink control information (DCI) that schedules the communication between the UE and the RAN on the one or more scheduled cells, the DCI comprising one or more frequency domain resource allocation (FDRA) fields and a BWP index corresponding to the one or more BWP sizes for the one or more scheduled cells, wherein the one or more FDRA fields correspond to the one or more scheduled cells and comprise the one or more RIVs;
• and
• performing the communication with the UE on the one or more scheduled cells.
