Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] Embodiments of the present invention include the following steps:

[0020] 1) The radio network controller sends signaling to the base station, where the signaling includes notifying the user equipment of support capability information for combined use of MIMO and downlink 64QAM;

[0021] 2) The base station receives the signaling information, obtains the support capability of the user equipment for combined use of MIMO and downlink 64QAM from the signaling information, and saves it.

[0022] In the above steps, the signaling may be any of the following: a radio link establishment request message, a radio link addition request message, a radio link reconfiguration preparation message, and a radio link reconfiguration request message.

[0023] In the above steps, if the user equipment supports combined use of MIMO and downlink 64QAM, t...

Abstract

The present invention discloses a method which is used by a base station to be informed that the user equipment supports the combination of MIMO and downlink 64QAM, and comprises the following steps: (1) a radio network controller sends signaling to the base station, and the signaling comprises the information that the user equipment of the base station supports the combination of the multi-input multi-output modulation and the modulation of integral amplitude of 64 times of the downlink; and (2) the base station receives the signaling and acquires the information from the signaling message that the user equipment supports the combination of the multi-input multi-output modulation and the modulation of integral amplitude of 64 times of the downlink. When the user equipment MIMO is activated and the base station completes the self-adapting code modulation, the modulation mode can be determined according to the capacity of the user equipment, thus guaranteeing that user equipment normally receives the data.

Description

technical field [0001] The present invention relates to a high-speed packet access system in a mobile communication system, and in particular to a base station learning user equipment MIMO (Multiple Input Multiple Output, multiple input multiple output) and downlink 64QAM (64 Quadrature Amplitude Modulation, 64 integral amplitude modulation) combined support ability method. Background technique [0002] In the optimization of existing system technology, in order to improve user experience quality and system throughput, high-speed downlink packet access technology is also constantly evolving. At present, 16QAM (16Quadrature Amplitude Modulation: 16 integral amplitude modulation) has been introduced in the downlink direction. Higher order modulation: 64QAM and MIMO transmit and receive diversity technology. However, the current protocol is mutually exclusive for the use of 64QAM and MIMO in the downlink, that is, if the 64QAM modulation mode is used in the downlink, MIMO cann...
