Abstract
A method and a device for allocating radio resources in in-band full duplex communication are disclosed. The method of a terminal comprises the steps of: receiving slot format information from a base station; confirming a DL section, an FL section, and an UL section on the basis of the slot format information; receiving UL subband information from the base station; and regarding a DL resource area as an UL resource area if an UL subband indicated by the UL subband information overlaps the DL resource area in the DL section.
Claims20
A method of a terminal, comprising:
- receiving slot format information from a base station;
- identifying a downlink (DL) period, a flexible (FL) period, and an uplink (UL) period based on the slot format information;
- receiving UL subband information from the base station;
- and
- in response to that a UL subband indicated by the UL subband information overlaps with a DL resource region within the DL period, considering the DL resource region as a UL resource region,
- wherein a period in which the DL resource region overlapping with the UL subband exists is a subband full duplex (SBFD) period, and a period in which the DL resource region overlapping with the UL subband does not exist is a non-SBFD period.
A method of a base station, comprising:
- transmitting, to a terminal, slot format information indicating a downlink (DL) period, a flexible (FL) period, and an uplink (UL) period;
- transmitting UL subband information to the terminal;
- in response to that a UL subband indicated by the UL subband information overlaps with a DL resource region within the DL period, considering the DL resource region as a UL resource region;
- and
- performing communication with the terminal in a subband full duplex (SBFD) period which is a period in which the DL resource region overlapping with the UL subband exists and a non-SFBD period which is a period in which the DL resource region overlapping with the UL subband does not exist.
A terminal comprising at least one processor,
- wherein the at least one processor causes the terminal to perform:
- receiving slot format information from a base station;
- identifying a downlink (DL) period, a flexible (FL) period, and an uplink (UL) period based on the slot format information;
- receiving UL subband information from the base station;
- and
- in response to that a UL subband indicated by the UL subband information overlaps with a DL resource region within the DL period, considering the DL resource region as a UL resource region,
- wherein a period in which the DL resource region overlapping with the UL subband exists is a subband full duplex (SBFD) period, and a period in which the DL resource region overlapping with the UL subband does not exist is a non-SBFD period.
