Abstract

The embodiment of the invention discloses a method, device and system for transmitting communication signals, relating to the communication field and strengthening network receiving performance. In the method, a multi-frequency receiver is used for carrying out frequency band division on radio-frequency signals received by an antenna so as to obtain radio-frequency signals with different frequency bands; a first part of radio-frequency signals in a scheduled frequency band are sent to a radio-frequency unit, so that the radio-frequency unit is used for converting the received first part of radio-frequency signals in the scheduled frequency band into first baseband digital signals which are sent to a baseband processing unit, wherein the first part of radio-frequency signals are received by the radio-frequency unit; and the radio-frequency unit is used for converting a second part of radio-frequency signals in the scheduled frequency band into second baseband digital signals which are sent to the baseband processing unit by a digital baseband interface, or the second baseband digital signals are sent to a first radio-frequency module by the digital baseband interface, so that the first radio-frequency module is used for sending the second baseband digital signals to the baseband processing unit. The method, device and system provided by the embodiment are mainly applied to a multi-frequency receiving process.

Description

technical field

[0001] The present invention relates to the communication field, in particular to a communication signal transmission method, device and system. Background technique

[0002] With the continuous application of new wireless standard technologies such as WCDMA (Wideband Code Division Multiple Access) and LTE (Long Term Evolution, long-term evolution), there are more and more new frequency bands and multi-frequency co-site scenarios. At the same time, with the development of antenna technology, the frequency band supported by the antenna is also expanding. At present, the broadband antenna can support 790-960MHz or 1710-2690MHz. Take the high-frequency band as an example, that is, a pair of 1710-2690MHz dual-polarized antenna can support three frequency bands of 1800MHz, 2100MHz and 2600MHz or more transceivers of different frequency bands share the antenna at the same time. With the increase in capacity requirements, operators need to make full use of frequenc...
