Method and apparatus for multi-transmission/reception point power headroom reporting in a wireless communication system
地域：
Taipei
摘要
A method and apparatus are disclosed. In an example from the perspective of a User Equipment (UE), the UE receives an uplink (UL) grant. The UL grant is indicative of a first Physical Uplink Shared Channel (PUSCH) transmission on a first Transmission/Reception Point (TRP) of a first cell. The UL grant is not indicative of a PUSCH transmission on a second TRP of the first cell. The UE transmits a Power Headroom Reporting (PHR) Medium Access Control (MAC) Control Element (CE). Based on the UL grant, the PHR MAC CE is indicative of a first power headroom (PH), associated with the first TRP, based on a real PUSCH transmission, and is indicative of a second PH, associated with the second TRP, based on a reference PUSCH transmission.

- 3> obtain the value of the Type 1 power headroom from the physical layer for the corresponding uplink carrier of the PCell;
- 3> obtain the value for the corresponding PCMAX,f,c field from the physical layer;
- 3> if mpe-Reporting is configured:
- 4> obtain the P-MPR value for the corresponding MPE field from the physical layer;
- 4> set the corresponding P field according to the obtained P-MPR value.
- 3> instruct the Multiplexing and Assembly procedure to generate and transmit the Single Entry PHR MAC CE as defined in clause 6.1.3.8 based on the values reported by the physical layer.
- 3> start or restart the mpe-ProhibitTimer;
- 3> cancel triggered MPE P-MPR reporting for Serving Cells included in the PHR MAC CE.
