Method and apparatus for channel usage in unlicensed spectrum considering beamformed transmission in a wireless communication system
地域：
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.

- PRACH
- SRS
- DM-RS
- Other channels and reference signals are not precluded
- For the case of TRP and UE have Tx/Rx beam correspondence
- For the case of TRP has no Tx/Rx beam correspondence and/or UE has no Tx/Rx beam correspondence
There are some agreements on beam management and/or group common PDCCH in RAN1 # AH1_NR meeting, as described in the Final Report of 3GPP TSG RAN WG1 # AH1_NR v1.0.0 (Spokane, USA, 16-20 Jan. 2017) as follows:
