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 method also includes the UE transmitting the SR based on a first SR configuration of the multiple SR configurations, wherein the first SR configuration is associated with a highest priority logical channel having data available for transmission when the MAC control element is triggered.

說明書

  • 4. Logical channel group identity
  • 5. Logical channel priority
  • 6. QoS flow ID

    • And the UE may directly associate SR configuration with logical channel(s) explicitly or implicitly. For example, if SR configuration includes logical channel (group) identity, the data belonging to certain logical channel (group) arrives may trigger BSR and may also trigger corresponding SR based on SR configuration. As another example, if each SR configuration includes numerology information for performing SR transmission, data belonging to certain logical channel (group) arrives, then a SR configuration using same numerology as the logical channel (group) suggested to use will be triggered.

    Method 2—A new SR with multiple bits is defined in NR. The multiple bits in SR could be designed as one or multiple fields. Each field could be used to indicate one or multiple information listed as follows:

    • 1. Numerology
    • 2. TTI length/duration (e.g. maximum TTI threshold, specific TTI length/duration (range))
    • 3. Logical channel identity (e.g. bitmaps representing different logical channels, field for indicating LCID)
    • 4. Logical channel group identity
    • 5. Logical channel priority
    • 6. QoS flow ID
