specific Embodiment 1

[0147]When the coordinating node in COMP uses the new carrier type and compatible carrier type to serve the UE, it is further assumed that the new carrier type agrees not to use CRS, PDCCH, PHICH, PCFICH, continue to use PBCH, R8 PSS / SSS, and the base station sends The signaling structure includes:

[0148] Identification information of quasi-co-sited cells, number of CRS ports, MBSFN subframe configuration information, carrier type information, and reference signal configuration information for synchronous tracking. The specific signaling structure is as follows:

[0149]

[0150]

[0151] The signaling structure shows that cell 1 and cell 2 satisfy the quasi-co-site relationship, and the cells are described by using the cell physical ID and the CSI-RS index configured by the cell respectively. The configurations in cell 1 and cell 2 include CRS port, MBSFN subframe configuration, carrier type, synchronous tracking reference signal, synchronous tracking CSI-RS configur...

specific Embodiment 2

[0154] An illustration of adding relevant information in CSI-RS-ConfigNZP to form the signaling structure of the present invention is as follows:

[0155]

[0156]

[0157] The carrier type at this time identifies the cell or carrier or TP described by the parameter qcl-ScramblingIdentity-r11, and the cell or carrier or TP identified by the parameter scramblingIdentity-r11 in the signaling structure defaults to a compatible carrier type for the UE, so there is no Introduce carrier type. This signaling structure is suitable for the case where new carriers that are not independently operated participate in coordinated or aggregated operations. At this time, the cell identified by the parameter qcl-ScramblingIdentity-r11 adopts a certain type of new carrier that is not independently operated, and is specified by the parameter scramblingIdentity-r11 The identified cell uses a compatible carrier type by default. When the UE finds that the cell identified by the parameter scra...

specific Embodiment 3

[0160] An illustration of adding relevant information in CSI-RS-ConfigNZP to form the signaling structure of the present invention is as follows:

[0161]

[0162] At this time, the cells in the signaling structure are respectively configured with carrier type parameters, the first carrier type parameter identifies the carrier type of the cell described by the parameter scramblingIdentity-r11, and the second carrier type parameter identifies the carrier type parameter by the parameter qcl-ScramblingIdentity-r11 Describes the carrier type of the cell.

[0163] If only the carrier type signaling cannot help the UE to know the channel and signaling configuration information in the carrier, the carrier type parameters at this time can be replaced by specific channel and signaling configuration parameters. For example, a possible replacement method is : Replace the carrier type parameter with the following channel and signaling configuration information: PCFICH configuration inf...

Abstract

A method for generating carrier configuration information, a network side device, and a user equipment. The method comprises: a network side device agreeing with a UE on a signaling structure of carrier configuration information and sending the signaling structure to the UE, the signaling structure at least comprising one of the following parameters: identification information about a quasi co-site cell, CRS port quantity or CRS configuration information, MBSFN subframe configuration information, carrier type information, CSI-RS configuration information used for RSRP measurement, CSI-RS configuration information used for synchronous tracking, CSI-RS configuration information used for CSI measurement, reference signal configuration information used for synchronous tracking, and DMRS configuration information used for synchronous tracking.

Description

technical field [0001] The present invention relates to the field of mobile wireless communication, in particular to a method for generating carrier configuration information, network side equipment and user equipment when multiple nodes in a wireless communication system are cooperatively transmitting for UE. Background technique [0002] With the development of the mobile communication industry and the increasing demand for mobile data services, people have higher and higher requirements for the speed and quality of service (Qos) of mobile communication. Therefore, in the third generation mobile communication (3rd generation Generation, 3G) before large-scale commercial use, the research and development of the next-generation mobile communication system has already begun, and the typical one is the long-term evolution initiated by the 3rd Generation Partnership Project (3GPP). (Long Term Evolution, LTE) project, the highest spectrum bandwidth that the LTE system can provid...
