Abstract
A method and apparatus are disclosed for requesting resources in a wireless communication system. The method includes sending a first SA in a first SA period at a first timing. The method also includes considering a data available in the UE at a second timing, wherein the data needs to be transmitted and the second timing is later than the first timing. The method further includes skipping a resource associated with the first SA for sending the data at a third timing, wherein the third timing is later than the second timing and earlier than a second SA period which is later than the first SA period. In addition, the method includes sending a second SA in the second SA period. Furthermore, the method includes sending the data on a resource associated with the SA.
Claims21
A method for a first User Equipment (UE) to request resources in a wireless communication system, comprising:
- sending a first scheduling assignment (SA) for device to device (D2D) communication to a second UE at a first timing in a first SA period, wherein after some transmission opportunities associated with the first SA are used for D2D transmissions, there are remaining transmission opportunities in the first SA period;
- considering a new D2D data available in the first UE at a second timing in the first SA period, wherein the new D2D data needs to be transmitted and the second timing is later than the first timing;
- determining whether to use the remaining transmission opportunities in the first SA period to transmit the new D2D data;
- skipping and not use a resource associated with the first SA for transmitting the new D2D data at a third timing in the first SA period, wherein the third timing is later than the second timing;
- sending a second SA to the second UE in a second SA period, wherein the second SA period is later than the first SA period;
- and
- transmitting the new D2D data to the second UE on a resource associated with the second SA.
A method for a first User Equipment (UE) to request resources in a wireless communication system, comprising:
- establishing a connection with a base station (BS);
- sending a first scheduling request (SR) to the BS;
- receiving a control signal from the BS;
- sending a scheduling assignment (SA) for device to device (D2D) communication to a second UE associated with the control signal at a first timing in a SA period, wherein after some transmission opportunities associated with the SA are used for D2D transmissions, there are remaining transmission opportunities in the SA period;
- considering a new D2D data available in the first UE at a second timing, wherein the new D2D data needs to be transmitted and the second timing is later than the first timing;
- determining whether to use the remaining transmission opportunities in the SA period to transmit the new D2D data;
- and
- using the remaining transmission opportunities in the SA period to transmit the new D2D data to the second UE on the available resource at a third timing, wherein the third timing is later than the second timing.

- considering a new D2D data available in the first UE at a second timing in the SA period, wherein the new D2D data needs to be transmitted and the second timing is later than the first timing;
- triggering a Buffer Status Report (BSR) associated with the new D2D data;
- cancelling the BSR since resources of the remaining transmission opportunities associated with the SA can accommodate the new D2D data;
- and
- transmitting the new D2D data to the second UE on the resources of the remaining transmission opportunities at a third timing in the SA period, wherein the third timing is later than the second timing.
