The combination of Dinan and Xu does not teach to trigger a first PRACH transmission to the first TRP and a second PRACH transmission to the second TRP.
Molavian teaches to trigger a first PRACH transmission to the first TRP and a second PRACH transmission to the second TRP.

For example, a UE can start a first RA procedure or corresponding first PRACH transmission(s) to a first TRP earlier than a second RA procedure or corresponding second PRACH transmission(s) to a second TRP )
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to combine teaching of Molavian with the teaching of Dinan and Xu because Molavian teaches that PRACH transmission to TRPs would at improve link adaptation for a random access procedure based on CSI reporting by a UE using a PRACH transmission.(Molavian [0109])
14. (Cancelled)
As to claim 15. The combination of Dinan and Xu, does not teach wherein the UE receives the PDCCH order including a parameter mapping to either the first TRP, the second TRP, or both the first TRP and the second TRP to trigger the PRACH transmission to the first TRP, the second TRP, or both the first TRP and the second TRP.

([0215] [0274] gNB signaling such as a PDCCH order, can initiate two concurrent RA procedures; order of RAR reception can be independent from the order of RA initiation or PRACH transmission. For example, a UE can start a first RA procedure or corresponding first PRACH transmission(s) to a first TRP earlier than a second RA procedure or corresponding second PRACH transmission(s) to a second TRP )
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to combine teaching of Molavian with the teaching of Dinan and Xu because Molavian teaches that PRACH transmission to TRPs would at improve link adaptation for a random access procedure based on CSI reporting by a UE using a PRACH transmission.(Molavian [0109])

and drop the first UL transmission or the second UL transmission. ([0087] dropping of overlapping UL transmissions to multiple TRPs, such as when two PRACH transmissions to two TRPs overlap in time)

As to claim 20 The combination of Dinan and Xu does not teach wherein the processor of the UE is further configured to: determine that a first downlink (DL) reception from the first TRP and a second DL reception from the second TRP have a reception timing difference exceeding a maximum reception timing difference; and report the reception timing difference to the network.
Takeda teaches wherein the processor of the UE is further configured to:
determine that a first downlink (DL) reception from the first TRP and a second DL reception from the second TRP have a reception timing difference exceeding a maximum reception timing difference; ([0115][0136] UE 205 may identify the receive timing difference between two downlink cells (e.g., base stations, cells, TRPs, etc.) exceeds X microseconds)
and
report the reception timing difference to the network. ([0108] the report/message may be triggered by an event, such as UE 205 determining that a maximum transmit timing difference of two uplink carriers within a frequency band exceeds a certain value; message may be reported to either or both of the cell-groups)
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to combine teaching of Takeda with the teaching of Dinan and Xu because Takeda teaches that when downlink timing difference exceeding threshold base station would schedule or configure a downlink communication for UE to reduce timing difference thereby mitigating a performance degradation of the downlink reception.
