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

說明書
In case 2, the following possible options for handling SR triggering for a timer and/or counter controlled based control element are considered and proposed:
Option 1 (Pre-defined rule for UE to select SR configuration)—The UE could possibly trigger SR transmission according to SR configuration associated with default or access numerology when the control element 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 a numerology used for performing initial access. 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).
Alternatively, the UE could always triggers SR transmission according to SR configuration associated with the largest or the smallest numerology which the UE could use. The numerology that a UE could use would need to take UE capability into account. In one embodiment, the numerology that a UE could use would 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.
