Embodiment Construction

[0241] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0242] Please refer to figure 1 , which shows a schematic diagram of an implementation environment involved in various embodiments of the present invention, the implementation environment provides a wireless communication system, specifically a MIMO system, see figure 1 , the implementation environment may include: a base station 01 and multiple UEs. For example, as figure 1 As shown, this implementation environment is described by taking multiple UEs including UE-02, UE-03 and UE-04 as an example.

[0243] Each of the multiple UEs has multiple TMs (such as TM1-TM10), and each TM may include at least two transmission schemes, and each UE may use any transmission scheme in any TM for data transmission. Taking UE-02 as an example for ...

Abstract

The invention discloses a transmission scheme indication method, a data transmission method, a device and a system, belonging to the technical field of communication. The transmission scheme indication method includes: generating transmission scheme indication information, where the transmission scheme indication information is used to indicate one transmission scheme among at least two transmission schemes included in the current transmission mode, and the at least two transmission schemes include beamforming transmit diversity transmission Scheme; send transmission scheme indication information. The present invention solves the problem that the flexibility of the UE to transmit data is low, and achieves the effect of improving the flexibility of the UE to transmit data. The invention is used for data transmission.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a transmission scheme indication method, a data transmission method, a device and a system. Background technique [0002] In the long-term evolution (English: Long Term Evolution; abbreviation: LTE) or subsequent long-term evolution (English: Long term evolution-advanced; abbreviation: LTE-A) system, there are multiple transmission modes (English: Transmission mode; abbreviation: TM ), such as TM1-TM10, the base station can instruct the UE to use the corresponding TM for data transmission through radio resource control (Radio Resource Control; Send the transmission scheme indication information to the user equipment (English: User equipment; UE for short) according to the channel quality, the transmission scheme indication information can indicate a transmission scheme in the TM currently adopted by the UE, and the UE can indicate the information according to the t...
