AI Technical Summary
Technical Problem
In existing technologies, the number of DMRS ports is limited, resulting in insufficient system capacity and an inability to effectively reuse more users and layers.
Method used
Time-division multiplexing is achieved by increasing the number of time units in multiple port groups, thereby expanding the number of ports without increasing DMRS overhead and increasing system capacity through time-division multiplexing.
Benefits of technology
Without increasing DMRS overhead, the system capacity was increased, enabling space reuse for more users and layers.

Abstract
The present disclosure relates to a communication method, apparatus, device and system, a storage medium and a program product, and relates to the technical field of communications, the method comprising: executing at least one of sending a PUSCH to a network device or receiving a PDSCH sent by the network device on at least one port. The at least one port comprises a plurality of ports, the plurality of ports comprise a plurality of port groups, the plurality of port groups comprise a first port group, the first port group comprises at least one port, and the first port group is associated with a first time unit. The PUSCH or the PDSCH sends and / or receives on the first time unit, and the PUSCH or the PDSCH carries the first DMRS; or, the PUSCH or the PDSCH is not transmitted and / or received on the first time unit, and the PUSCH or the PDSCH does not bear the first DMRS. The method and the device are used for expanding ports and increasing the number of the ports, so that the system capacity can be increased under the condition that the overhead of the DMRS is not increased, namely, more user numbers and layers can be spatially multiplexed.
