  This paper studies the performance of three typical network coordination
schemes, i.e., dynamic point selection, fully overlapped non-coherent joint
transmission (F-NCJT), and nonfully overlapped NCJT (NF-NCJT), in 3GPP new
radio (NR) in indoor scenarios via system level simulation. Each of these
schemes requires a different level of user data and channel state information
(CSI) report exchange among coordinated transmission reception points (TRPs)
depending on centralized or distributed schedulers. Scheduling strategies of
these network coordination schemes are briefly discussed. It has been
demonstrated that distributed network coordination schemes (e.g., NFNCJT) can
still perform reasonably well; a result which has important implications to the
design of the fifth generation (5G) cellular network architecture.
