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

Since MAC CE has no latency requirement in LTE, the latency requirement for MAC CE may need to be defined and/or to be configured for applying this solution. One possible way is to associate the timer controlled based MAC CE with certain TTI duration and/or certain numerology (in related configuration). The associated TTI duration and/or numerology may also be used for timer counting.
Solution 5 (Use SR configuration related to latest SR triggering event to perform SR transmission)—The UE will initiate SR transmission based on SR configuration related to the new event (e.g. higher priority data coming or retx-BSR timer expiry, or special event . . . ). For example, assuming the Timer controlled based MAC CE is triggered when SR for uplink BSR is transmitted, the SR configuration used for current SR transmission will be changed to SR configuration related to Timer controlled based MAC CE.
Solution 6 (Always prioritize uplink data need over the special event (e.g. Timer controlled based MAC CE))—If the new coming event is Timer controlled based MAC CE and current SR transmission reflects uplink data need, the UE will keep using the current SR configuration. On the contrary, if new coming event is for uplink data need and current SR transmission is for Timer controlled based MAC CE, the UE will change the current SR configuration to a different SR configuration related to the new coming event.
