Embodiment Construction

[0020] It should be emphasized that in practical applications, the connection between the antenna and the splitter, the connection between the antenna and the radio frequency unit, the connection between the splitter and the radio frequency unit, and the connection between different splitters, etc., usually The ports are not directly connected, but connected through connection components such as feeders. Because this is common knowledge in the field, the present invention does not describe the connection method in detail in the description of the embodiment. The concepts of "connection" and "connection" mentioned in the present invention include the connection between the connected parts. Connecting components such as feeders are connected.

[0021] The present invention provides a device and method for supporting transmit diversity technology in a single-antenna scenario. According to an embodiment of the present invention, the data from multiple (for example, 2) radio frequ...

Abstract

The invention provides a device and a method for supporting a transmission diversity technique by a single antenna. According to an implementation mode, data from a plurality of radio frequency ports (such as two radio frequency ports) of a radio frequency unit with mTnR channels and capable of supporting the transmission diversity technique are merged, the data of each radio frequency port are mutually orthogonal and contain the same information, and the single antenna (such as a single leakage cable) transmits the merged data. When any radio frequency port and / or radio frequency channel and / or feeder line connected with the radio frequency port of the radio frequency unit is faulted, the single antenna can still keep wireless communication without interruption, and wireless communication quality in the scene of the single antenna is improved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to the application of MIMO technology in a single-antenna deployment scenario. Background technique [0002] Among wireless communication technologies, MIMO (Multiple Input Multiple Output) technology has been relatively mature and widely used in commercial use. As an important MIMO technology, transmit diversity is applied to LTE wireless communication system and UMTS system using STTD technology. The use of transmit diversity can improve the reliability of wireless links. For example, in a wireless communication system using transmit diversity technology, the base station can have multiple transmit and receive channels. When one of the transmit and / or receive channels fails, although The quality of communication will be reduced, but data transmission will still be maintained. [0003] However, in actual deployment scenarios, in some cases, only one antenna can be us...
