Problems solved by technology

For example, a UE with four receiving antennas can simultaneously support a MIMO transmission mode with a maximum rank of 1, a MIMO transmission mode with a maximum rank of 2, and a MIMO transmission mode with a maximum rank of 4, while a UE with dual receiving antennas can simultaneously support a maximum rank of 1. The MIMO transmission mode and the MIMO transmission mode with a maximum rank of 2, the UE with a single receiving antenna can only support the MIMO transmission mode with a maximum rank of 1

[0065] See figure 1 , is the flow chart of the first embodiment of the HS-DPCCH information feedback control method provided by the present invention, the method comprising:

[0066] At S100, receive user equipment category information uploaded by the user equipment, and determine at least one MIMO transmission mode supported by the user equipment according to the user equipment category information. The UE category information may include: whether the UE supports MIMO, the maximum number of MIMO transmission streams supported by the UE, and the like. For example, assuming that the network side equipment uses 4 transmit antennas, according to the provisions of the agreement, UEs that support MIMO in this communication system may be divided into three types. One type supports a maximum number of MIMO transmission streams of 1, indicating that the UE MIMO transmission mode with a maximum rank of 1 is supported; a maximum number of supported MIMO transmission streams is 2, indic...

Abstract

The embodiment of the invention discloses a feedback control method, feedback method and equipment for HS-DPCCH information. Network side equipment receives user equipment class information uploaded by user equipment, at least one MIMO transmission mode supported by the user equipment is determined according to the user equipment class information, an MIMO transmission mode is chosen from the at least one MIMO transmission mode, and mode configuration information or mode activating information indicating the MIMO transmission mode is generated; the mode configuration information or the mode activating information is issued to the user equipment, so the user equipment feeds back the HS-DPCCH information corresponding to the MIMO transmission mode in type. Through the adoption of the feedback control method, feedback method and equipment, feedback precision of the HS-DPCCH information can be improved, and signaling expenses under four branch MIMO modes are reduced.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a feedback control method, feedback method and equipment for HS-DPCCH information. Background technique [0002] Starting from version 5, 3GPP provides a high-speed downlink packet access mechanism (High Speed ​​Downlink Packet Access, HSDPA), which is used to provide high-speed transmission of downlink packets on the air interface. It consists of high-speed downlink shared channel (HighSpeed ​​Downlink Shared Channel, HS-DSCH), high-speed downlink physical shared channel (High SpeedPhysical Downlink Shared Channel, HS-PDSCH), high-speed downlink shared control channel (SharedControl Channel for HS-DSCH, HS-SCCH ) and HS-DSCH dedicated physical control channel (DedicatedPhysical Control Channel for HS-DSCH, HS-DPCCH) interact to achieve. And the MAC-hs (HSDPA scheduling entity) in the base station (NodeB) schedules the HS-DSCH radio resources, and sends the scheduling infor...
