Problems solved by technology

CoMP requires multiple nodes to send downlink service data or control channels to a UE in a coordinated manner, so that the UE needs to know the configuration information of different nodes, but R8 / R9 / 10 UEs only access the main serving cell when they initially access , so only the system information of the primary serving cell is obtained, so when other nodes transmit data for the UE, the UE may receive data incorrectly because it does not know the system information of the relevant node

Embodiment 1

[0192] Assuming that the version of UE1 is R11, the network side configures to the receiving side a set of CoMP measurement set configuration information including multiple coordinated measurement nodes through high-level signaling. The configuration information includes multiple sets of CSI-RS configuration information, multiple sets of corresponding cell designation and the corresponding CRS port number. UE1 receives the above-mentioned high-layer signaling sent by the network side to obtain multiple sets of CSI-RS configuration information, multiple sets of corresponding cell identifiers and corresponding numbers of CRS ports. When the network side needs to send downlink data to UE1, the network side also needs to add the cell index of the corresponding node in the downlink authorization information, and then send the service data according to the number of CRS ports and time-frequency position information of the node in the cell index. That is, the network side needs to co...

[0195] Assuming that the version of UE1 is R11, the network side configures to the receiving side a set of CoMP measurement set configuration information including multiple coordinated measurement nodes through high-level signaling. The configuration information includes multiple sets of CSI-RS configuration information, multiple sets of corresponding cell designation and the corresponding CRS port number. UE1 receives the high-layer signaling sent by the network side to obtain multiple sets of CSI-RS configuration information, multiple sets of corresponding cell identifiers and corresponding numbers of CRS ports. When the network side needs to send downlink data to UE1, the network side performs data mapping according to the cell identifier and CRS port information of the first CSI-RS configuration information, that is, the network side needs to consider avoiding the time-frequency position of the above-mentioned CRS when mapping data resource element.

[0198] Assuming that the version of UE1 is R11, the network side configures to the receiving side a set of CoMP measurement set configuration information including multiple coordinated measurement nodes through high-level signaling. The configuration information includes multiple sets of CSI-RS configuration information, multiple sets of corresponding cell label, multiple sets of corresponding CRS port numbers, and multiple sets of corresponding MBSFN subframe configuration information. UE1 receives the high-level signaling sent by the network side to obtain multiple sets of CSI-RS configuration information, multiple sets of corresponding cell labels, multiple sets of corresponding CRS port numbers, and multiple sets of corresponding MBSFN subframe configuration information. When the network side needs to send downlink data to UE1, the network side also needs to add the cell index of the corresponding node in the downlink authorization information, and then send the service dat...

Abstract

The invention discloses a method and device for processing the mapping position of data resources. The network side can notify the receiving side of the mapping position of receiving data resources on different subframes through high-level signaling or physical layer signaling, so that the receiving side can correctly receive And detect the corresponding data. The receiving side can receive the high-layer signaling or physical layer signaling sent by the network side, determine the mapping position of receiving data resources on different subframes based on this, and correctly receive and detect the corresponding data according to the mapping position. The data resource mapping position processing technology of the present invention ensures that the UE can correctly determine the data resource mapping position in different scenarios and CoMP transmission modes, so as to correctly receive and detect the required data, and can save data resources as much as possible to transmit service data .

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for processing data resource mapping positions. Background technique [0002] After a long term evolution (Long Term Evolution, LTE) system has gone through several versions (Release, R) 8 / 9 / 10, it starts to study the R11 technology again. At present, some R8 products have been gradually commercialized, and R9 and R10 products are yet to be further planned. [0003] After going through the stages of R8 and R9, R10 added many new features on the basis of the first two, such as DMRS (Demodulation Reference Signal, demodulation reference signal), CSI-RS (Channel State Information Reference Signal, channel state information reference Signal) and other pilot characteristics, 8-antenna support and other transmission and feedback characteristics, etc., especially eICIC (ehanced Inter-Cell Interference Cancellin, Inter-Cell Interference Cancellation Enhancement) tec...
