Problems solved by technology

[0004] If only single-antenna transmission technology is used for downlink at the base station side, the demodulation threshold of the terminal side in the information receiving process will be relatively high, so that the coverage of the base station and the information receiving effect of the terminal side will inevitably be limited

Abstract

The invention relates to a method and a device for sending and receiving information, comprising: configuring a message comprising antenna transmission indication information, wherein the antenna transmission indication information is used for indicating single-antenna transmission or multi-antenna transmission during information transmission process; and then sending the message comprising antenna transmission indication information. Thus, a receiving end can use single-antenna reception manner or multi-antenna reception manner to realize the receiving operation of the information based on the antenna transmission indication information after the information comprising antenna transmission indication information is received. The implementation of the embodiment of the invention can improve the network coverage in the communication network by effectively making use of multi-antenna transmission technology, thereby reducing the terminal demodulation threshold and improving the receiving performance of the terminal.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an information sending and receiving method and device. Background technique [0002] At present, in the WiMAX (Worldwide Interoperability for Microwave Reception) network, the First PUSCZone (First Partially Used Sub-Carrier Zone) on the base station side only uses single-antenna transmission technology for information transmission. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] If only single-antenna transmission technology is used for downlink at the base station side, the demodulation threshold of the terminal side in the information receiving process will be relatively high, which will inevitably lead to restrictions on the coverage of the base station and the information receiving effect on the terminal side. Contents of the invention [0005] Embodimen...
