Method and device for determining transmission resources

1 . A method performed by a user equipment (UE), the method comprising:

receiving, from a base station, first downlink control information (DCI) for scheduling a physical downlink shared channel (PDSCH), wherein the first DCI includes first frequency domain resource assignment (FDRA) information;

identifying a first total number of resource elements (REs) for the PDSCH, based on multiplying a minimum of 156 and a number of REs for the PDSCH in a physical resource block (PRB) by a first number of first PRBs minus a second number of second PRBs among the first PRBs, wherein the first PRBs are identified based on the first FDRA information, and wherein the second PRBs are not used for the PDSCH; and

identifying a first transport block size (TBS) for the PDSCH based on the first total number.

wherein a second TBS for the PUSCH is based on the second total number.

5 . A user equipment (UE) comprising:

at least one transceiver;

at least one processor communicatively coupled to the at least one transceiver; and

at least one memory, communicatively coupled to the at least one processor, storing instructions executable by the at least one processor individually or in any combination to cause the UE to

receive, from a base station, first downlink control information (DCI) for scheduling a physical downlink shared channel (PDSCH), wherein the first DCI first frequency domain resource assignment (FDRA) information,

identify a first total number of resource elements (REs) for the PDSCH, based on multiplying a minimum of 156 and a number of REs for the PDSCH in a physical resource block (PRB) by a first number of first PRBs minus a second number of second PRBs among the first PRBs, wherein the first PRBs are identified based on the first FDRA information and wherein the second PRBs are not used for the PDSCH, and

identify a first transport block size (TBS) for the PDSCH based on the first total number.

6 . The UE of claim 5 , wherein the instructions further cause the UE to:

receive, from the base station, a second DCI for scheduling a physical uplink shared channel (PUSCH), wherein the second DCI includes second FDRA information,

identify a second total number of REs for the PUSCH, using a third number of third PRBs minus a fourth number of fourth PRBs among the third PRBs, wherein the third PRBs are identified based on the second FDRA information and wherein the fourth PRBs are not used for the PUSCH, and

identify a second TBS for the PUSCH based on the second total number.

7 . A base station comprising:

at least one transceiver;

at least one processor communicatively coupled to the at least one transceiver; and

at least one memory, communicatively coupled to the at least one processor, storing instructions executable by the at least one processor individually or in any combination to cause the base station to:

transmit, to a user equipment (UE), first downlink control information (DCI) for scheduling a physical downlink shared channel (PDSCH), wherein the first DCI includes first frequency domain resource assignment (FDRA) information, and

transmit, to the UE, the PDSCH,

wherein a first total number of resource elements (REs) for the PDSCH is based on multiplying a minimum of 156 and a number of REs for the PDSCH in a physical resource block (PRB) by a first number of first PRBs minus a second number of second PRBs among the first PRBs,

wherein the first PRBs are indicated by the first FDRA information,

wherein the second PRBs are not used for the PDSCH, and

wherein a first transport block size (TBS) for the PDSCH is based on the first total number.

8 . The base station of claim 7 , wherein the instructions further cause the base station to:

transmit, to the UE, a second DCI for scheduling a physical uplink shared channel (PUSCH), wherein the second DCI includes second FDRA information, and

receive, from the UE, the PUSCH,

wherein a second total number of REs for the PUSCH is based on a third number of third PRBs minus a fourth number of fourth PRBs among the third PRBs,
