The information represents by multiple bits SR and multiple SR configurations could be different or have certain level overlap. For example, multiple bits SR are used to indicate specific LCID within certain group of logical channels, while different SR configurations are used to indicate whether data is available in different group of logical channels. The specific LCID could be used to identify logical channel with highest priority or shortest TTI and/or numerology with the group of logical channels which having data. As another example, multiple bits SR and different SR configuration are used to indicate different information. The multiple bits SR is used to indicate TTI length/duration information and the multiple SR configurations are used to indicate different numerologies.
On the other hand, there are still some possible cases not covered by the agreement. It is not clear how to handle SR triggering/setting for those cases. Those possible cases are observed and listed below.
Case 1: Sidelink BSR
