Abstract
A method and apparatus are disclosed for performing buffer status reporting in a wireless communication system. The method includes a D2D (Device-to-Device) data arriving in the UE. The method also includes triggering a ProSe (Proximity-based Service) BSR (Buffer Status Report). The method further includes deriving a buffer size value by at least considering an amount of oncoming data. In addition, the method includes sending the ProSe BSR.
Claims11
A method of a UE (User Equipment) for performing buffer status reporting in a wireless communication system, the method comprising:
- a D2D (Device-to-Device) data arriving in the UE;
- triggering a ProSe (Proximity-based Service) BSR (Buffer Status Report);
- deriving a buffer size value by at least considering an amount of oncoming data;
- and
- sending the ProSe BSR.
A UE (User Equipment) for performing buffer status reporting in a wireless communication system, wherein a D2D (Device-to-Device) data arriving in the UE, 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:
- trigger a ProSe (Proximity-based Service) BSR (Buffer Status Report);
- derive a buffer size value by at least considering an amount of the oncoming data;
- and
- send the ProSe BSR.
A method of a UE (User Equipment) for performing buffer status reporting in a wireless communication system, the method comprising:
- a first D2D (Device-to-Device) data arriving in the UE;
- sending a first SR (Scheduling Request) and receiving a first UL (Uplink) grant;
- sending a first ProSe (Proximity-based Service) BSR (Buffer Status Report) by using the first UL grant in a first SA (Scheduling Assignment)/Data cycle at a first timing;
- and
- triggering or sending a second ProSe BSR if an amount of D2D data arrives after the first timing exceeds a threshold.
A method of a UE (User Equipment) in a wireless communication system, the method comprising:
- a first D2D (Device-to-Device) data associated with a first group session communication arriving in the UE;
- sending a first SR (Scheduling Request) and receiving a first UL (Uplink) grant;
- sending a first ProSe (Proximity-based Service) BSR (Buffer Status Report) by using the first UL grant in a first SA (Scheduling Assignment)/Data cycle;
- a second D2D data associated with a second group session communication arriving in the UE;
- sending a second SR and receiving a second UL grant;
- and
- sending a second ProSe BSR by using the second UL grant in the first SA/Data cycle.
A method of a UE (User Equipment) for performing buffer status reporting in a wireless communication system, the method comprising:
- a first D2D (Device-to-Device) data associated with a first group session communication arriving in the UE;
- sending a first SR (Scheduling Request), and receiving a first UL (Uplink) grant from the eNB;
- sending a first ProSe (Proximity-based Service) BSR (Buffer Status Report) by using the first UL grant;
- receiving a first D2D grant in a first SA/Data cycle;
- receiving a second D2D grant in the first SA/Data cycle;
- using the second D2D grant to overwrite the first D2D grant, and not using the first D2D grant since the first D2D grant is overwritten by the second D2D grant;
- and
- sending a SA associated with the second D2D grant.
