Coordinated multiple point transmission and reception

摘要

A method implemented in a mobile communications network supporting coordinated multiple point transmission and reception (CoMP) is disclosed. The method includes transmitting, to a user equipment (UE), data in a physical downlink shared channel (PDSCH), and transmitting a reference signal to the UE, wherein a union of resource elements (REs) allocated for reference signals transmitted from a subset of a plurality of transmission points (TPs) in a CoMP set are excluded from resource mapping for transmitting the data to the UE. Other methods, systems, and apparatuses also are disclosed.

1. A method implemented in a mobile communications network supporting coordinated multiple point transmission and reception (CoMP), the method comprising:
transmitting, to a user equipment (UE), data in a physical downlink shared channel (PDSCH); transmitting a reference signal to the UE; and signalling reference signal configurations semi-statically, wherein a union of resource elements (REs) allocated for reference signals configured with a measurement set of a plurality of configurations are excluded from resource mapping for transmitting the data to the UE, wherein the reference signal configurations comprise reference signal RE mapping pattern, and wherein the reference signal RE mapping pattern includes a frequency shift of reference signal position for each of the measurement of the plurality of configurations, the number of reference signal antenna ports for each of the measurement of the plurality of configurations, a maximum number of reference signal antenna ports, and a cell identity (cell ID) value.
