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

Moreover, for increasing system scheduling flexibility, it is beneficial to allow base station to schedule resource on different numerologies or with different TTI durations, instead of only numerologies and/or TTI durations informed by SR transmission. One possible rule is to let UE also monitor control channel which can schedule numerology smaller or larger than numerologies information carried by SR transmission. The range for how large or how small could be configured by base station and/or decided based on predefined rule (e.g. until largest or smallest numerology UE is configured with). For URLLC service, larger numerology resource could be also suitable for a UE from latency perspective. For eMTC service, the smaller numerology could be suitable for a UE from low complexity perspective and reliability perspective.
Whether UE will also monitor smaller or larger numerology may be:
- 1. Configured by network
- 2. Decided by UE itself based on ongoing service and/or current SR transmission(s) (e.g. SR request TTI/numerology less than a threshold, SR triggered for certain logical channel(s))
- 3. Decided based on UE category/type/complexity
- 4. Decided based on UE subscription
Moreover, since the UE may have multiple control channels for different numerologies, the UE may monitor other control channel which are not largest or smallest based on conditions other than SR transmission. The conditions other than SR transmission could be one or multiple options listed in below:
