Abstract
A method and a device for transmitting and receiving a signal in a wireless communication system, according to one embodiment of the present invention, comprise: receiving downlink control information (DCI) for scheduling a physical uplink shared channel (PUSCH); and transmitting the PUSCH on the basis of the DCI. The PUSCH is transmitted in a certain number of resource blocks (RB), and the certain number of RBs may be (i) at most the number of RBs allocated by the DCI, and (ii) the greatest number that is a multiple of 2, 3, and/or 5.
Claims12
A method of transmitting and receiving a signal by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving downlink control information (DCI) for scheduling a physical uplink shared channel (PUSCH);
- and
- transmitting the PUSCH based on the DCI,
- wherein the PUSCH is transmitted in a specific number of resource blocks (RBs),
- wherein the specific number is a largest number which is (i) equal to or less than the number of RBs allocated by the DCI and (ii) a multiple of 2, 3, and/or 5, and
- wherein based on the DCI being received in a common search space (CSS), the PUSCH is transmitted in (i) an RB-set having a lowest index among uplink RB-sets overlapping in a frequency domain with a control channel element (CCE) having a lowest index in which the DCI is detected, and (ii) an RB-set having a lowest index in an uplink bandwidth part (BWP) in the absence of a UL RB-set overlapping with the CCE.
A user equipment (UE) for transmitting and receiving a signal in a wireless communication system, the UE comprising:
- at least one transceiver;
- at least one processor;
- and
- at least one memory operably coupled to the at least one processor and storing instructions which, when executed, cause the at least one processor to perform specific operations,
- wherein the specific operations include:
- receiving downlink control information (DCI) for scheduling a physical uplink shared channel (PUSCH);
- and
- transmitting the PUSCH based on the DCI,
- wherein the PUSCH is transmitted in a specific number of resource blocks (RBs),
- wherein the specific number is a largest number which is (i) equal to or less than the number of RBs allocated by the DCI and (ii) a multiple of 2, 3, and/or 5, and
- wherein based on the DCI being received in a common search space (CSS), the PUSCH is transmitted in (i) an RB-set having a lowest index among uplink RB-sets overlapping in a frequency domain with a control channel element (CCE) having a lowest index in which the DCI is detected, and (ii) an RB-set having a lowest index in an uplink bandwidth part (BWP) in the absence of a UL RB-set overlapping with the CCE.
An apparatus for a user equipment (UE), comprising:
- at least one processor;
- and
- at least one computer memory operably coupled to the at least one processor and storing instructions which, when executed, cause the at least one processor to perform operations,
- wherein the operations include:
- receiving downlink control information (DCI) for scheduling a physical uplink shared channel (PUSCH);
- and
- transmitting the PUSCH based on the DCI,
- wherein the PUSCH is transmitted in a specific number of resource blocks (RBs),
- wherein the specific number is a largest number which is (i) equal to or less than the number of RBs allocated by the DCI and (ii) a multiple of 2, 3, and/or 5, and
- wherein based on the DCI being received in a common search space (CSS), the PUSCH is transmitted in (i) an RB-set having a lowest index among uplink RB-sets overlapping in a frequency domain with a control channel element (CCE) having a lowest index in which the DCI is detected, and (ii) an RB-set having a lowest index in an uplink bandwidth part (BWP) in the absence of a UL RB-set overlapping with the CCE.
