Option 1 (Pre-defined rule for UE to select SR configuration and to set multiple bits SR accordingly)—Possibly, UE triggers and sets SR transmission according to SR configuration associated with default or initial access numerology when the timer/counter control based MAC CE needs to trigger SR. The default numerology could be default numerology defined in specification for control element to request resource. The default numerology could be numerology used for receiving system information in RRC_IDLE state and/or RRC_INACTIVE state. The default numerology could be different for different UEs (e.g. NB-IoT UE and normal UE may have different default numerologies due to UE capability).
Another possibility could be that UE always triggers and sets SR transmission according to SR configuration associated with the largest or the smallest numerology which the UE can use. The numerology which a UE can use will need to take UE capability into account. In one embodiment, the numerology which a UE can use will also need to take configuration provided from network into account. If the UE does not have a configuration related to certain numerology, the UE may not be able to transmit SR on that numerology even the UE is capable to use. The configuration could be SR configuration.
Yet another possibility could be that UE always triggers SR configuration with the densest SR transmission opportunity. Moreover, the numerology could be replaced by one or multiple TTI/numerology information (e.g. LCG and/or TTI length, etc.) mentioned in the description of Method 3. Alternatively, considering all possible simple rules mentioned above, another possibility could be network configures which rule a UE shall follow when new MAC control element is triggered.
