In the case of dense networking, when the location of the terminal changes, it is necessary to frequently switch between different small base stations. come with additional signaling overhead.

The virtual cell consists of a master transmission point (master TP) and multiple It consists of a service transmission node (slave transmission point, slave TP). Among them, the master TP is responsible for all high-level control signaling, allocating wireless resources, and scheduling data transmission and reception. The slave TP performs collaborative transmission according to the instructions of the master TP and does not perform resource transmission. distribute.
