METHOD, SYSTEM, AND APPARATUS FOR NOTIFYING AND DETERMINING ANTENNA PORT POSITION RELATIONSHIP

摘要

A method, system and apparatus for notifying and determining an antenna port location relationship are disclosed. A network side configures an indication signaling of a CSI-RS referenced by a DMRS, and/or a first enabling indication signaling used for indicating whether the indication signaling of the CSI-RS referenced by the DMRS is enabled; or the network side further configures an indication signaling of a CRS referenced by each set of CSI-RSs which are quasi-co-located, and/or a second enabling indication signaling used for indicating whether the indication signaling of the CRS referenced by each set of CSI-RSs which are quasi-co-located is enabled. In the above scheme, a terminal is enabled to determine a reference signal port referenced in time-frequency synchronization, thereby providing a time-frequency synchronization precision.

1. A method for notifying an antenna port location relationship, comprising:
a network side configuring a indication signaling of a Channel State Information Reference Signal (CSI-RS) referenced by a Demodulation Reference Signal (DMRS), and/or a first enabling indication signaling used for indicating whether the indication signaling of the CSI-RS referenced by the DMRS is enabled, the network side configuring a transmission mode indication signaling.
