Embodiment 1

[0030] image 3 It is a flowchart of a control signaling transmission method provided by Embodiment 1 of the present invention. Please refer to image 3 , the method includes:

[0031] Step 301: the base station sends a control signaling to a mobile station configured in an open-loop multi-antenna (MIMO) mode to send location indication information;

[0032] Wherein, the control signaling transmission position indication information is used to indicate the transmission position of the control signaling, where the transmission position may be in the control area, that is, the traditional PDCCH area, or in the data area, that is, the traditional PDSCH area.

[0033] Step 302: If the transmission position of the control signaling indicated by the control signaling transmission position indication information is located in the data area, the base station adopts open-loop multi-antenna (MIMO, Multiple Input Multiple Output) or transmit diversity (TxD, transmit diversity) to sen...

Abstract

The embodiment of the invention provides a transmission method and a device for a control signaling. The method comprises the steps of sending the position indication information of a control signaling to a mobile station configured in the open-loop and multi-antenna mode from a base station; if the position indication information of the control signaling indicates that the sending position of the control signaling is located within a data region, sending the control signaling in the data region by the base station in the open-loop and multi-antenna mode or in the transmit diversity mode. According to the method and the device provided in the embodiments of the invention, when the number of to-be-scheduled mobile stations in a community needs to be increased so as to cause the increased scheduling information required to be sent by one sub frame, the control signaling of the mobile station configured in the open-loop and multi-antenna transmitting mode is transmitted within the data region. Therefore, the user scheduling is increased, and the throughput of the system is improved. The limited capacity problem of the PDCCH is solved.

Description

[0001] This application is a divisional application of an invention patent application with an application date of July 27, 2011, an application number of 201180069496.2, and an invention title of "A Transmission Method and Device for Control Signaling". technical field [0002] The present invention relates to the communication field, in particular to a control signaling transmission method and device. Background technique [0003] In a Long Term Evolution (LTE, Long Term Evolution) system, a physical downlink control channel (PDCCH, physical downlink control channel) is used to transmit control information, including downlink scheduling information (DL-Grant), uplink scheduling information (UL-Grant), power control information, etc. The specific signaling transmitted in the PDCCH is called downlink control information (DCI, downlink control information). The base station multiplexes the PDCCHs of all mobile stations in the cell and sends them in the first few OFDM symbols...
