Problems solved by technology

However, in the LTE R11 stage, it is possible to introduce multiple remote radio heads (RRH, Remote Radio Header) with the same cell ID. If the previous notification method is used, the receiving side cannot distinguish the time / frequency positions of different RRH channel state information reference signals. , resulting in erroneous measurements, there is currently no implementation scheme that provides signaling notification of RRH measurement sets

Abstract

The invention discloses a signaling informing method and system of a multipoint cooperative measurement set. The signaling informing method comprises the following steps: a network side configures a cooperative measurement set channel state information reference signal configuring signaling through a non-zero power channel state information reference signal configuring signaling, and / or zero power channel state information state information reference signal configuring signal, and / or bitmap sequence indication signaling and informs a multipoint cooperative measurement set of a receiving side; and the receiving side determines the size of the multipoint cooperative measurement set according to the configured cooperative measurement set channel state information reference signal configuring information, and measures state information of a plurality of configured channels. According to the invention, in an LTE (Long Term Evolution) R11 state, under the condition that the introduced multiple remote radio frequency heads have the same cell IDs, the signaling informing of the multipoint cooperative measurement set is realized.

Description

technical field [0001] The present invention relates to a long term evolution advanced system (LTE-Advanced, Long term evolution advanced system), in particular to a signaling notification method and system for realizing coordinated multi-point measurement set based on channel state information reference signal. Background technique [0002] In LTE Release8 / 9, in order to measure channel quality and demodulate received data symbols, the concept of Common Reference Signal (CRS, Common Reference Signal) is introduced. In this way, the user equipment (UE, User Equipment) can perform channel measurement through the CRS, which provides a basis for the UE to perform cell reselection and handover to a target cell. In addition, when the UE is in the connected state to measure the channel quality, when the interference level is high, the physical layer can disconnect the UE through high-layer-related radio link connection failure signaling. [0003] In LTE R10, in order to further i...
