Another possibility could be that UE always SR transmission according to SR configuration with the densest SR transmission opportunity. Yet another possibility could be that UE triggers SR transmission on all SR configurations the UE being configured. Moreover, the numerology could be replaced by one or multiple TTI/numerology information (e.g. LCG and/or TTI length, . . . ) mentioned in the description of Method 1. Alternatively, considering all possible simple rules mentioned above, another possibility could be network configures which rule a UE shall follow when timer/counter control based MAC CE is triggered.
Option 2 (Network configures the association between such timer/counter control based MAC CE and SR configuration)—The network could possibly provide numerology and/or TTI information to a service (e.g. sidelink, MBMS, V2X, V2V, relay, MTC, URLLC, IoT etc.). A MAC control element related to the service will trigger SR configuration by similar rule as logical channel with data. The MAC control element will trigger SR transmission according to SR configuration associated with the numerology and/or TTI information. The numerology and/or TTI information could be provided in service configuration (e.g. sidelink communication configuration, sidelink discovery configuration, etc.).
Alternatively, the network could possibly provide numerology and/or TTI information to a MAC control element. More specifically, the numerology and/or TTI information could be provided to specific timer or counter for handling timer/counter controlled based MAC CE in case 2. 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.
