Multi-mode terminal and signal transmitting and receiving method thereof

Abstract

The invention provides a multi-mode terminal and a signal transmitting and receiving method of the multi-mode terminal. The multi-mode terminal comprises a radio frequency (RF) transceiver set, a selective network module and multi-mode baseband processing modules. The RF transceiver set is used for performing RF processing on downgoing signals in multiple modes and upgoing signals strobed by the selective network module; the selective network module is used for selecting the corresponding multi-mode baseband processing modules for the downgoing signals processed by the RF transceiver set in an RF mode and is used for selecting corresponding RF transceivers in the RF transceiver set for the upgoing signals processed by the multi-mode baseband processing modules in a baseband mode; the multi-mode baseband processing modules are used for performing baseband processing on the downgoing signals strobed by the selective network module and the upgoing signals in the multiple modes. The multi-mode terminal is compatible with multiple multi-mode combination modes through the selective network module, so that resources are used reasonably.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a multi-mode terminal and a method for sending and receiving signals thereof. Background technique [0002] As people have higher and higher requirements for communication speed and quality, communication means and communication services are also diversified and optional, and the development of multi-mode terminals is also changing with each passing day. [0003] From the perspective of the market, the second-generation mobile communication system (2G), the third-generation mobile communication system (3G) and the long-term evolution (LTE) and other standards will coexist for a long time, and LTE network construction adopts hotspot area coverage , coupled with the problems of 3G network coverage and other aspects, mobile phone terminals that only support a single standard network will bring great inconvenience and waste to operators and users. Operators and service ...
