Problems solved by technology

[0004] However, there is currently no way to notify the network side of the MU-MIMO capability of the terminal, so that the network side cannot know whether the terminal supports MU-MIMO and ultimately cannot realize the MU-MIMO function

Embodiment 1

[0075] Figure 4 It is a flow chart of a method for notifying MU-MIMO capabilities during a terminal transition to a CELL_FACH state according to preferred embodiment 1 of the present invention, including the following steps:

[0076] Step 402, the terminal (UE) initiates an RRC connection establishment request message to the network side, and reports the MU-MIMO capability of the terminal to the network side in the RRC connection establishment request message, and the MU-MIMO capability indication information element is shown in Table 1;

[0077] Step 404, the NodeB packs the RRC connection establishment request message after receiving the RRC connection establishment request message, and through the user plane, for example, through the E-DCH FP (Enhanced-Dedicated Channel Frame Protocol, Enhanced Dedicated Channel Frame Protocol) frame, the RRC connection carrying the terminal MU-MIMO capability is established The request message is sent to the RNC, and at this time, the pac...

Embodiment approach 2

[0080] Figure 5 It is a flow chart of a method for notifying MU-MIMO capabilities during a terminal transition to a CELL FACH state according to the second preferred embodiment of the present invention, including the following steps:

[0081] Step 502, the terminal sends an RRC connection establishment complete message to the network side, and reports the MU-MIMO capability of the terminal to the network side in the RRC connection establishment complete message, and the MU-MIMO capability indication information element is shown in Table 1;

[0082] Step 504, after receiving the RRC connection establishment complete message, the NodeB packs and sends the RRC connection establishment complete message carrying the terminal MU-MIMO capability to the RNC through the user plane, for example, through the E-DCH FP frame, at this time, the packet is according to the E-DCH FP frame structure;

[0083] Step 506, the RNC receives the E-DCH FP frame data and parses the RRC connection est...

Abstract

A method and system for informing about Multi-User Multi-Input Multi-Output (MU-MIMO) capability of a terminal are provided in the present invention. Wherein the method includes: the terminal sends a Radio Resource Control (RRC) message to a radio network controller, wherein the RRC message carries the information for indicating the MU-MIMO capability of the terminal; the radio network controller parses the RRC message and obtains the MU-MIMO capability of the terminal; the radio network controller informs a base station of the parsed MU-MIMO capability of the terminal through a user plane. The present invention enables the RNC to bring the MU-MIMO capability of the terminal to a NodeB through the user plane, enables the NodeB to obtain the MU-MIMO capability of the terminal and then to match a plurality of users supporting the MU-MIMO capability, and accomplishes the function for sending a plurality of data streams for a plurality of users at the same time.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and system for notifying a terminal MU-MIMO capability. Background technique [0002] SU-MIMO (Single User MIMO (Multiple Input and Multiple Output, Multiple Input and Multiple Output)) technology sends two data streams for one user at the same time, which can improve the peak throughput of a single user. In order to support SU-MIMO technology, the terminal The implementation puts forward higher requirements, including the need to support a new special default midamble allocation method, increase the cache to support more processes, and support a stronger joint detection algorithm. [0003] Compared with SU-MIMO technology, MU-MIMO (multi-user MIMO) is to send multiple data streams for multiple users at the same time, using MU-MIMO technology to realize SDMA (Space Division Multiple Access, space division multiple access), which can Improve the average user throughput...
