METHOD AND APPARATUS FOR HANDLING MULTIPLE D2D (DEVICE TO DEVICE) GRANTS IN A SA (SCHEDULING ASSIGNMENT) PERIOD IN A WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method of a user equipment (UE) for handling multiple D2D grants for multiple sidelinks in decreasing order of priority, comprising:
- a first UE participates in a first sidelink and a second sidelink, wherein a priority of the first sidelink is higher than a priority of the second sidelink;
the first UE receives a first D2D grant and a second D2D grant from a base station in a first SA period;
the first UE serves the first sidelink with the first D2D grant and afterward, the first UE cannot serve the first sidelink with another D2D grant for the same SA period as the first D2D grant;
the first UE serves the second sidelink with the second D2D grant and afterward, the first UE cannot serve the second sidelink with another D2D grant for the same SA period as the second D2D grant; and
the first UE uses the first D2D grant for transmitting available data of the first sidelink and uses the second D2D grant for transmitting available data of the second sidelink in a second SA period, wherein the second SA period and the first SA period are different SA periods.

Abstract
A method and apparatus are disclosed for handling multiple D2D grants for multiple sidelinks in decreasing order of priority. In one embodiment, the method includes a first UE participates in a first sidelink and a second sidelink, wherein a priority of the first sidelink is higher than a priority of the second sidelink. The method also includes the first UE receiving a first D2D grant and a second D2D grant from a base station in a first SA period. The method further includes the first UE serving the first sidelink with the first D2D grant and afterward, the first UE cannot serve the first sidelink with another D2D grant for the same SA period as the first D2D grant. In addition, the method includes the first UE serving the second sidelink with the second D2D grant and afterward, the first UE cannot serve the second sidelink with another D2D grant for the same SA period as the second D2D grant. Furthermore, the method includes the first UE using the first D2D grant for transmitting available data of the first sidelink and using the second D2D grant for transmitting available data of the second sidelink in a second SA period, wherein the second SA period and the first SA period are different SA periods.

14. A first UE for handling multiple D2D grants for multiple sidelinks in decreasing order of priority, comprising:
-
a control circuit; a processor installed in the control circuit; and a memory installed in the control circuit and operatively coupled to the processor; wherein the processor is configured to execute a program code stored in the memory to; participate in a first sidelink and a second sidelink, wherein a priority of the first sidelink is higher than a priority of the second sidelink; receive a first D2D grant and a second D2D grant from a base station in a first SA period; serve the first sidelink with the first D2D grant and afterward cannot serve the first sidelink with another D2D grant for the same SA period as the first D2D grant; serve the second sidelink with the second D2D grant and afterward cannot serve the second sidelink with another D2D grant for the same SA period as the second D2D grant; use the first D2D grant for transmitting available data of the first sidelink and use the second D2D grant for transmitting available data of the second sidelink in a second SA period, wherein the first SA period and the second SA period are different SA periods. - View Dependent Claims (15, 16, 17, 18, 19)
