Method and apparatus for requesting resource for control element transmission in a wireless communication system
摘要

Another possibility could be that network provides numerology and/or TTI information to a MAC control element. The MAC control element will trigger SR transmission according to SR configuration associated with the numerology and/or TTI information. Moreover, the MAC control element may or may not be limited to only use uplink resource related to the numerology and/or TTI information for transmission.
Yet another possibility could be that a SR configuration includes a MAC control element information and/or how to set multiple bits SR for the MAC CE (e.g. LCID(s) of MAC control element(s), MAC control element corresponding bitmap, etc.). Moreover, the numerology and/or TTI information could be replaced by one or multiple information mentioned in the description of Method 3.
Another possibility could be that network provides SR configuration index/identity and/or how to set multiple bits SR in service configuration related to the MAC control element. And the UE triggers SR according to the SR configuration index/identity for the MAC control element and also set the multiple bits SR based on the service configuration.
Option 3 (UE implementation)—All SR configurations and/or multiple bits SR settings can be candidate. The UE can decide select which SR configuration and how to set it.
Option 4 (Defined SR configuration and multiple bits SR setting for control element (e.g. Sidelink BSR))—Possibly, UE will be configured a SR configuration and specific multiple bits SR setting used to dedicatedly handle one or multiple control element(s). There could be more than one SR configuration and/or specific SR setting used to dedicated for handling control elements.
