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.

If a UE determines that a Type 1 power headroom report for an activated serving cell is based on an actual PUSCH transmission then, for PUSCH transmission occasion i on active UL BWP b of carrier f of serving cell c, the UE computes the Type 1 power headroom report as PHtype1,b,f,c(i,j,qd,l)=PCMAX,f,c(i)?{PO_PUSCH,b,f,c(j)+10 log10(2μ·MRB,b,f,cPUSCH(i))+αb,f,c(j)·PLb,f,c(qd)+ΔTF,b,f,c(i)+fb,f,c(i,l)}?? [dB] where PCMAX,f,c (i) PO_PUSCH,b,f,c j) MRB,b,f,cPUSCH (i) αb,f,c (j), PLb,f,c(qd), ΔTF,b,f,c (i) and fb,f,c (i,l) are defined in Clause 7.1.1.
