Abstract
A method and apparatus for triggering of transmission carrier or resource reselection in a wireless communication system is provided. A first wireless device reserves a set of resources comprising at least a first resource and a second resource for sidelink transmission. When (i) the sidelink transmission using the first resource overlaps with an uplink transmission, and (ii) a priority of the uplink transmission is higher than a threshold, the first wireless device clears the first resource from the set of resources, and adds a third resource to the set of resources.
Claims14
A method performed by a first wireless device configured to operate in a wireless communication system, the method comprising:
- reserving a set of resources comprising at least a first resource and a second resource for sidelink transmission;
- determining the set of resources as a sidelink grant;
- based on (i) de-prioritization of the sidelink transmission related to the first resource with respect to an uplink transmission, (ii) the sidelink transmission related to the first resource overlapping with the uplink transmission, and (iii) the first wireless device being not able to simultaneously perform the sidelink transmission related to the first resource and the uplink transmission:
- removing the first resource from the sidelink grant;
- reserving a third resource for the sidelink grant;
- and
- performing the sidelink transmission to a second wireless device based on the sidelink grant.
A first wireless device configured to operate in a wireless communication system, the wireless device comprising:
- at least one transceiver;
- at least one processor;
- and
- at least one computer memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
- reserving a set of resources comprising at least a first resource and a second resource for sidelink transmission;
- determining the set of resources as a sidelink grant;
- based on (i) de-prioritization of the sidelink transmission related to the first resource with respect to an uplink transmission, (ii) the sidelink transmission related to the first resource overlapping with the uplink transmission, and (iii) the first wireless device being not able to simultaneously perform the sidelink transmission related to the first resource and the uplink transmission:
- removing the first resource from the sidelink grant;
- reserving a third resource for the sidelink grant;
- and
- performing the sidelink transmission to a second wireless device based on the sidelink grant.
A processing apparatus configured to control a first wireless device in a wireless communication system, the processing apparatus comprising:
- at least one processor;
- and
- at least one computer memory operably connectable to the at least one processor,
- wherein the at least one processor is configured to perform operations comprising:
- reserving a set of resources comprising at least a first resource and a second resource for sidelink transmission;
- determining the set of resources as a sidelink grant;
- based on (i) de-prioritization of the sidelink transmission related to the first resource with respect to an uplink transmission, (ii) the sidelink transmission related to the first resource overlapping with the uplink transmission, and (iii) the first wireless device being not able to simultaneously perform the sidelink transmission related to the first resource and the uplink transmission:
- removing the first resource from the sidelink grant;
- reserving a third resource for the sidelink grant;
- and
- controlling to perform the sidelink transmission to a second wireless device based on the sidelink grant.
