Method and apparatus for requesting resource for control element transmission in a wireless communication system
摘要
說明書
Different cases based on the alternatives and the methods for SR reflecting numerology/TTI information are discussed below. And the assumption is based on UE having multiple control resource sets or called control channels (e.g. multiple downlink control channels). Each control resource set could apply one of the three alternatives on data numerology scheduling. Moreover, the multiple control resource set could be allocated for one cell or for carrier aggregation case. The different control resource sets may be separated from time and/or frequency and/or code domain.
Method 1+Alternative 1 or Alternative 2
Case 1: Special SR Triggering Event (e.g. Sidelink BSR, Timer and/or Counter Controlled Based Control Element (e.g. Retx-BSR Timer), Potential New Uplink MAC Control Element Which Can Trigger SR)
Option 1 (Monitoring control channel(s) responsible for scheduling numerology related to SR configuration(s) with triggered SR)—In this option, since each SR configuration is associated with one or multiple numerologies, the SR transmission based on specific configuration can inform base station about the TTI duration and/or numerology of uplink need. It is reasonable for base station to schedule resource based on the received SR transmission(s). Hence, control channel which can provide corresponding scheduling should be monitored.
