Problems solved by technology

However, the current protocol is mutually exclusive for the use of downlink 64QAM and MIMO, that is, if the downlink uses 64QAM modulation, MIMO cannot be used; if the downlink uses MIMO, downlink 64QAM cannot be used
That is to say, although both the base station and the user equipment support the capabilities of MIMO and downlink 64QAM at the same time, they cannot enjoy the higher throughput brought about by the simultaneous use of the two.

Abstract

The present invention discloses a method which is used by a high-speed physical downlink shared channel combination to adopt the technology of multi-input, multi-output and high-order modulation. At first, the wireless network controller adopts the signaling message to judge whether the configuration of the drift wireless network controller can simultaneously allow the multi-input multi-output MIMO technology and the modulation method of integral amplitude of 64 times of the downlink; the drift wireless network controller receives and stores the information of the configuration of the drift wireless network controller. In the method, when the data packet simultaneously adopts the MIMO and the modulation method of 64QAM so that the node under the control of the drift wireless network controller activates the MIMO, the high-speed physical downlink shared channel is allowed to use the 64QAM for corresponding encoding; the user equipment is also suitable for decoding of the HS-SCCH formatof the downlink 64QAM, thus the normal communication of the user equipment is guaranteed.

Description

technical field [0001] The present invention relates to a method for using high-order modulation in a wireless communication system, in particular to a method for combining multiple-input multiple-output and high-order modulation techniques in a high-speed physical downlink shared channel. Background technique [0002] The access network contains one or more radio network subsystems. Each radio network subsystem is a subnet in the access network, which includes a radio network controller and one or more node Bs. The radio network controller is a network element responsible for controlling the radio resources of the access network; the main function of the node B is to process the physical layer of the air interface, and also perform some basic radio resource management operations. When a user equipment establishes a communication relationship with multiple radio network controllers, different radio network controllers are connected through the Iur port, and the radio networ...
