Abstract

The invention provides a control information transmitting method and a system, user equipment and a base station. The method includes that user experience (UE) carries parameter information of an E-transport format combination indicator (TFCI) and a reference serial number (RSN) on a S-E-dedicated physical control channel (DPCCH); the parameter information of the E-TFCI and the RSN are control information relevant to transmit data carried on a S-E-dedicated physical data channel (DPDCH) corresponding to the S-E-DPCCH. The UE sends the parameter information of the E-TFCI and the RSN to the base station on the S-E-DPDCH, wherein the parameter information of the E-TFCI is used to obtain auxiliary flow E-TFCI by the base station, the auxiliary flow E-TFCI and the RSN are used to receive data carried on the S-E-DPCCH by the base station. The technical scheme can make up the shortage of the lack of transmission mode of control information in underwriters laboratories (UL) multiple input multiple output (MIMO) in the prior art and provide an effective control information transmission scheme, so that the transmission of ascending data in UL MIMO systems is effectively guaranteed.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a control information transmission method and system, user equipment, and a base station. Background technique [0002] The Multiple Input Multiple Output (MIMO) system takes advantage of the spatial freedom of the wireless environment, and can achieve higher performance than the traditional Single Input Single Output (SISO) and Single Input without increasing the channel bandwidth. Input multiple output (Single Input Multiple Output; SIMO) system higher data transmission rate. In the downlink structure of the Universal Mobile Telecommunications System (UMTS) system, 2*2 MIMO, 64 quadrature amplitude modulation (Quadrature Amplitude Modulation; QAM) and multi-carrier technologies have been introduced, all of which bring The downlink data rate has been greatly improved. The improvement of the downlink data rate in the prior art effectively imp...
