Taipei
摘要
A method and apparatus are disclosed from the perspective of a UE (User Equipment). In one embodiment, the method includes the UE monitors or receives a control signal within a channel occupancy, wherein the control signal indicates a number of consecutive TTIs (Transmission Time Intervals) and TTI format(s) related information of the TTIs. The method further includes the UE derives transmission direction of symbols in the TTIs or functionality of symbols in the TTIs from the information. The method also includes the UE considers the last TTI of the indicated TTIs as an ending TTI of the channel occupancy. In addition, the method includes the UE performs DL (Downlink) data reception or UL (Uplink) data transmission until the ending TTI.

- UE movement, UE rotation, beam blocking:
- Change of beam at TRP, same beam at UE
- Same beam at TRP, change of beam at UE
- Change of beam at TRP, change of beam at UE
- Other cases are not precluded
There are some agreements on beam management in RAN1 #86 meeting, as described in the Final Report of 3GPP TSG RAN WG1 #86 v1.0.0 (Gothenburg, Sweden, 22-26 Aug. 2016) as follows:
