Method for processing physical resource and user equipment
View Patent ↗The present application provides a method for processing a physical resource, a user equipment, and a base station. The method for processing a physical resource includes the following steps: determining scheduled physical resource blocks (PRB) based on indication information of carrier sensing result of at least one received frequency sub-band and indication information of physical resource blocks; and receiving data on the scheduled PRBs.
1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, information on frequency sub-bands of which listen before talk (LBT) results are idle;
mapping virtual resource blocks (VRBs) in the frequency sub-bands of which the LBT results are idle, to physical resource blocks (PRBs); and
transmitting data in case that a result of the LBT is an idle state,
wherein the information is transmitted via group-common downlink control information (GC-DCI), and
after determining that the frequency sub-bands of which the LBT results are idle are inconsecutive and an interleaved allocation mode is used, the PRBs are consecutively numbered in the frequency sub-bands of which the LBT results are idle.
2. The method of claim 1 , further comprising performing a PRB bundling,
wherein the PRBs in a PRB group are located in one frequency sub-band or in a plurality frequency sub-bands based on the PRB bundling.
3. The method of claim 2 , wherein the PRB bundling is performed based on predetermined size information of a PRB group, to determine the PRB group.
4. The method of claim 3 , wherein PRBs in the PRB group are located in one frequency sub-band.
5. A terminal in a wireless communication system, the terminal comprising:
a transceiver; and
at least one processor coupled with the transceiver and configured to:
receive, from a base station, information on frequency sub-bands of which listen before talk (LBT) results are idle,
map virtual resource blocks (VRBs) in the frequency sub-bands of which the LBT results are ide, to physical resource blocks (PRBs), and
transmit data in case that a result of the LBT is an idle state,
wherein the information is transmitted via group-common downlink control information (GC-DCI), and
in case that the frequency sub-bands of which the LBT results are idle are inconsecutive and an interleaved allocation mode is used, the PRBs are consecutively numbered in the frequency sub-bands of which the LBT results are idle.
6. The terminal of claim 5 , wherein, the at least one processor is further configured to perform a PRB bundling, and
wherein the PRBs in a PRB group are located in one frequency sub-band or in plurality frequency sub-bands based on the PRB bundling.
7. The terminal of claim 6 , wherein the PRB bundling is performed based on predetermined size information of a PRB group, to determine the PRB group.
8. The terminal of claim 7 , wherein PRBs in the PRB group is located in one frequency sub-band.
