Method for resource indication and terminal device
View Patent ↗Methods for resource indication and a terminal device are provided in implementations of the disclosure. The method includes the following. A first terminal device transmits a shared resource set to a second terminal device through first signaling, where the shared resource set indicates transmission resources for sidelink (SL) communication.
1. A method for resource indication, comprising:
transmitting, by a first terminal device, a shared resource set to a second terminal device through first signaling, the shared resource set indicating transmission resources for sidelink (SL) communication;
wherein the first signaling is a sidelink control information (SCI) format 0-2;
wherein the SCI format 0-2 comprises M2 groups of bit fields, M2 is a positive integer, a number of the M2 groups of the bit fields is greater than or equal to a first value, and each of the M2 groups of the bit fields comprises at least one of:
a time-frequency-domain-resource indication field;
a resource-reservation-period indication field indicating a reservation period for each time-frequency-domain resource indicated by the time-frequency-domain-resource indication field; or
a resource-reservation-period-number indication field indicating number of reservation periods for time-frequency-domain resources indicated by the time-frequency-domain-resource indication field.
2. The method of claim 1 , wherein before transmitting, by the first terminal device, the shared resource set to the second terminal device through the first signaling, the method further comprises:
determining, by the first terminal device, the shared resource set according to a first indication from a network device, wherein the shared resource set comprises at least one of: at least one resource configured via type-1 configured grant (CG) or at least one resource configured via type-2 CG.
3. The method of claim 1 , wherein before transmitting, by the first terminal device, the shared resource set to the second terminal device through the first signaling, the method further comprises:
determining, by the first terminal device, an initial resource set according to a second indication from a network device; and
determining, by the first terminal device, the shared resource set according to the initial resource set, wherein the shared resource set is a subset of the initial resource set.
4. The method of claim 3 , wherein the initial resource set is represented as one or more resources configured via type-1 CG or a resource pool, and the shared resource set is represented as one or more resources configured via the type-1 CG or the resource pool.
5. The method of claim 1 , wherein the shared resource set comprises SL transmission resources currently used by the first terminal device or a superset of the SL transmission resources currently used by the first terminal device.
6. The method of claim 1 , wherein whether the SCI format 0-2 comprises a plurality of groups of bit fields is indicated by an SCI format 0-1 that schedules transmission of the SCI format 0-2.
7. A method for resource indication, comprising:
receiving, by a second terminal device, a shared resource set transmitted by a first terminal device through first signaling, the shared resource set indicating transmission resources for sidelink (SL) communication;
wherein the first signaling is a sidelink control information (SCI) format 0-2;
wherein the SCI format 0-2 comprises M2 groups of bit fields, M2 is a positive integer, a number of the M2 groups of the bit fields is greater than or equal to a first value, and each of the M2 groups of the bit fields comprises at least one of:
a time-frequency-domain-resource indication field;
a resource-reservation-period indication field indicating a reservation period for each time-frequency-domain resource indicated by the time-frequency-domain-resource indication field; or
a resource-reservation-period-number indication field indicating number of reservation periods for time-frequency-domain resources indicated by the time-frequency-domain-resource indication field.
8. The method of claim 7 , wherein the shared resource set comprises SL transmission resources currently used by the first terminal device or a superset of the SL transmission resources currently used by the first terminal device.
9. The method of claim 7 , wherein whether the SCI format 0-2 comprises a plurality of groups of bit fields is indicated by an SCI format 0-1 that schedules transmission of the SCI format 0-2.
10. A terminal device comprising:
a transceiver;
a processor; and
a memory storing a computer program;
wherein the computer program being executed by the processor to cause the transceiver to:
transmit a shared resource set to another terminal device through first signaling, the shared resource set indicating transmission resources for sidelink (SL) communication;
wherein the first signaling is a sidelink control information (SCI) format 0-2;
wherein the SCI format 0-2 comprises M2 groups of bit fields, M2 is a positive integer, a number of the M2 groups of the bit fields is greater than or equal to a first value, and each of the M2 groups of the bit fields comprises at least one of:
a time-frequency-domain-resource indication field;
a resource-reservation-period indication field indicating a reservation period for each time-frequency-domain resource indicated by the time-frequency-domain-resource indication field; or
a resource-reservation-period-number indication field indicating number of reservation periods for time-frequency-domain resources indicated by the time-frequency-domain-resource indication field.
11. The terminal device of claim 10 , wherein the computer program is further executed by the processor to cause the processor to determine the shared resource set according to a first indication from a network device, wherein the shared resource set comprises at least one of: at least one resource configured via type-1 configured grant (CG) or at least one resource configured via type-2 CG.
12. The terminal device of claim 10 , wherein the computer program is further executed by the processor to cause the processor to determine an initial resource set according to a second indication from a network device, and determine the shared resource set according to the initial resource set, wherein the shared resource set is a subset of the initial resource set.
13. The terminal device of claim 10 , wherein the shared resource set comprises SL transmission resources currently used by the terminal device or a superset of the SL transmission resources currently used by the terminal device.
14. The terminal device of claim 10 , wherein whether the SCI format 0-2 comprises a plurality of groups of bit fields is indicated by an SCI format 0-1 that schedules transmission of the SCI format 0-2.
