Abstract
Provided herein is a method for performing, by a first apparatus (100), resource selection in a wireless communication system. The method may include the steps of receiving system information including configuration information related to exceptional pools from a base station (200); selecting the first exceptional pool or the second exceptional pool, based on at least one of a physical layer problem, a connection re-establishment, a handover, or a normal resource pool which is unavailable; selecting a resource from the selected exceptional pool; and performing a sidelink (SL) communication using the resource.
Claims14
A method for performing, by a first device, wireless communication, the method comprising:
- obtaining information regarding at least one normal resource pool and information regarding an exceptional resource pool,
- wherein the at least one normal resource pool includes a resource by which the first device is allowed to transmit sidelink communication, and
- wherein the exceptional resource pool includes a resource by which the first device is allowed to transmit sidelink communication in an exceptional condition;
- and
- determining that a physical sidelink feedback channel (PSFCH) is configured for the at least one normal resource pool and the exceptional resource pool in case that at least a logical channel configured with a field which indicates a hybrid automatic repeat request (HARQ) feedback being enabled or disabled for the logical channel is set to enabled.
A first device for performing wireless communication, the first device comprising:
- one or more memories storing instructions;
- one or more transceivers;
- and
- one or more processors connected to the one or more memories and the one or more transceivers, wherein the one or more processors execute the instructions to:
- obtain information regarding at least one normal resource pool and information regarding an exceptional resource pool,
- wherein the at least one normal resource pool includes a resource by which the first device is allowed to transmit sidelink communication, and
- wherein the exceptional resource pool includes a resource by which the first device is allowed to transmit sidelink communication in an exceptional condition:
- and
- determine that a physical sidelink feedback channel (PSFCH) is configured for the at least one normal resource pool and the exceptional resource pool in case that at least a logical channel configured with a field which indicates a hybrid automatic repeat request (HARQ) feedback being enabled or disabled for the logical channel is set to enabled.
A device configured to control a first user equipment (UE), the device comprising:
- one or more processors;
- and
- one or more memories operably connectable to the one or more processors and storing instructions, wherein the one or more processors execute the instructions to:
- obtain information related to one exceptional pool;
- determine to use the one exceptional pool, based on occurrence of an exceptional case;
- obtain information regarding at least one normal resource pool and information regarding an exceptional resource pool,
- wherein the at least one normal resource pool includes a resource by which the first UE is allowed to transmit sidelink communication, and
- wherein the exceptional resource pool includes a resource by which the first UE is allowed to transmit sidelink communication in an exceptional condition:
- and
- determine that a physical sidelink feedback channel (PSFCH) is configured for the at least one normal resource pool and the exceptional resource pool in case that at least a logical channel configured with a field which indicates a hybrid automatic repeat request (HARQ) feedback being enabled or disabled for the logical channel is set to enabled.
