摘要
A method and apparatus are disclosed from the perspective of a UE, wherein the UE is allocated with multiple SR configurations by a network node. In one embodiment, the method includes the UE triggering a MAC control element if a timer expires. The method also includes the UE triggering a SR for the MAC control element.

The present Application claims the benefit of U.S. Provisional Patent Application Ser. No. 62/490,072 filed on Apr. 26, 2017 and U.S. Provisional Patent Application Ser. No. 62/519,718 filed on Jun. 14, 2017, the entire disclosures of which are incorporated herein in their entirety by reference.
This disclosure generally relates to wireless communication networks, and more particularly, to a method and apparatus for requesting resource control element transmission in a wireless communication system.
With the rapid rise in demand for communication of large amounts of data to and from mobile communication devices, traditional mobile voice communication networks are evolving into networks that communicate with Internet Protocol (IP) data packets. Such IP data packet communication can provide users of mobile communication devices with voice over IP, multimedia, multicast and on-demand communication services.
An exemplary network structure is an Evolved Universal Terrestrial Radio Access Network (E-UTRAN). The E-UTRAN system can provide high data throughput in order to realize the above-noted voice over IP and multimedia services. A new radio technology for the next generation (e.g., 5G) is currently being discussed by the 3GPP standards organization. Accordingly, changes to the current body of 3GPP standard are currently being submitted and considered to evolve and finalize the 3GPP standard.

The invention claimed is:1. A method of a UE (User Equipment), wherein the UE is allocated with multiple SR (Scheduling Request) configurations by a network node, comprising:starting a timer upon sending a first MAC (Medium Access Control) control element, wherein the first MAC control element is triggered due to data available for transmission; triggering a second MAC control element if the timer expires, wherein there are multiple logical channels still having data available for transmission when the timer expires; triggering a SR for the second MAC control element; selecting a first SR configuration among the multiple SR configurations, wherein the first SR configuration is associated with a highest priority logical channel among the multiple logical channels having data available for transmission when the second MAC control element is triggered, with the highest priority logical channel determined by comparing priorities of each of the multiple logical channels; and transmitting the SR based on the first SR configuration of the multiple SR configurations. 2. The method of claim 1 , wherein the timer is a retxBSR-Timer. 3. The method of claim 1 , wherein the first and second MAC control elements are BSR (Buffer Status Report). 4. The method of claim 1 , wherein the first SR configuration is associated with the highest priority logical channel based on an identity of the highest priority logical channel. 5. The method of claim 1 , further comprising:triggering the first MAC control element if the UE has data for any logical channels that belong to a Logical Channel Group. 6. A User Equipment (UE), comprising:a processor; and a memory operatively coupled to the processor, wherein the processor is configured to execute a program code to:start a timer upon sending a first MAC (Medium Access Control) control element, wherein the first MAC control element is triggered due to data available for transmission; trigger a second MAC control element if the timer expires, wherein there are multiple logical channels still having data available for transmission when the timer expires; trigger a SR (Scheduling Request) for the second MAC control element; select a first SR configuration among multiple SR configurations, wherein the first SR configuration is associated with a highest priority logical channel among the multiple logical channels having data available for transmission when the second MAC control element is triggered, with the highest priority logical channel determined by comparing priorities of each of the multiple logical channels; and transmit the SR based on the first SR configuration of the multiple SR configurations. 7.

The UE of claim 6 , wherein the first SR configuration is associated with the highest priority logical channel based on an identity of the highest priority logical channel. 10. The UE of claim 6 , wherein the processor is further configured to execute a program code stored in the memory to:trigger the first MAC control element if the UE has data for any of logical channels which belong to a Logical Channel Group. 11. A method of a UE (User Equipment), wherein the UE is allocated with a plurality of SR (Scheduling Request) configurations by a network node, comprising:starting a timer upon sending a first MAC (Medium Access Control) control element, wherein the first MAC control element is triggered due to data available for transmission; triggering a second MAC control element if the timer expires, wherein there are a plurality of logical channels having data available for transmission when the timer expires; triggering a SR for the second MAC control element; selecting a first SR configuration among the plurality of SR configurations, wherein the first SR configuration is associated with a highest priority logical channel among the plurality of logical channels having data available for transmission when the second MAC control element is triggered, with the highest priority logical channel determined by an identity of the highest priority logical channel; and transmitting the SR based on the first SR configuration of the plurality of SR configurations. 12. The method of claim 11 , wherein the timer is a retxBSR-Timer. 13. The method of claim 11 , wherein the first and second MAC control elements are BSR (Buffer Status Report). 14. The method of claim 11 , wherein at least one of the first and second MAC control elements is BSR. 15. The method of claim 11 , further comprising:triggering the first MAC control element if the UE has data for any logical channels that belong to a Logical Channel Group. 16.
