Method and apparatus for multi-transmission/reception point power headroom reporting in a wireless communication system

說明書
In some examples, the PHR MAC CE (e.g., the multi-TRP PHR MAC CE) may indicate and/or comprise multiple PH levels for a cell (e.g., for each cell, such as for each cell of one or more cells with which the UE communicates). Each PH level of the multiple PH levels may be associated with a measured PH report associated with a TRP of a cell. The multi-TRP PHR MAC CE may indicate a PH (e.g., one PH) for each TRP of a cell (e.g., one cell). For example, the multi-TRP PHR MAC CE may indicate a PH (e.g., one PH) for all TRPs of the cell (e.g., the multi-TRP PHR MAC CE may indicate a PH, such as one PH for each TRP of all TRPs of the cell). The multiple PH levels may comprise a Type 1 PH (e.g., a Type 1 PH report) based on a real PUSCH transmission (associated with a first TRP of the cell, for example) and a Type 1 PH (e.g., a Type 1 PH report) based on a reference PUSCH transmission (associated with a second TRP of the cell, for example). Whether to determine (e.g., calculate) the multiple PH levels for the cell based on the real PUSCH transmission or to determine (e.g., calculate) the multiple PH levels for the cell based on the reference PUSCH transmission may be based on a received UL grant indicating one or more PUSCH transmissions on the cell (such as based on one or more timings, such as one or more slots, of the one or more PUSCH transmissions).
For example, the UE may communicate with the cell via a first TRP and a second TRP. The UE may include two PH levels in a multi-TRP PHR MAC CE for the cell. Each PH level of the two PH levels indicates a measured PH report for the first TRP and the second TRP, respectively.
