Abstract
A resource assignment method performed by a user equipment (UE) is provided. The resource assignment method includes determining a target resource set for data transmission at a first time unit, selecting the earliest resource in time from the target resource set, wherein the selected resource is located at a second time unit, determining, at the second time unit and/or between the first time unit and the second time unit, whether the selected resource at the second time unit is available, and determining whether data is transmitted on the selected resource at the second time unit based on the result of the determination.
Claims14
A method performed by a terminal in a wireless communication system, the method comprising:
- initializing a set of resources with all candidate resources;
- excluding a resource from the set of resources based on a measured reference signal received power (RSRP) being higher than a threshold;
- in case that a number of remaining resources in the set of resources is smaller than a predetermined value, increasing the threshold and performing the initializing step;
- identifying that a resource for a sidelink transmission is re-evaluated based on the set of resources;
- selecting a resource for the sidelink transmission other than the re-evaluated resource;
- and
- performing a channel access procedure for a channel based on the selected resource.
A terminal in a wireless communication system, the terminal comprising:
- a transceiver;
- and
- a controller configured to:
- initialize a set of resources with all candidate resources,
- exclude a resource from the set of resources based on a measured reference signal received power (RSRP) being higher than a threshold,
- in case that a number of remaining resources in the set of resources is smaller than a predetermined value, increase the threshold and perform the initializing step,
- identify that a resource for a sidelink transmission is re-evaluated based on the set of resources,
- select a resource for the sidelink transmission other than the re-evaluated resource, and
- perform a channel access procedure for a channel based on the selected resource.
