Abstract

The invention provides a terminal and a method for transmitting and receiving multiple carriers thereof. The terminal comprises a multi-band antenna which is provided with a plurality of antenna structures and is used for transmitting or receiving carriers, corresponding to the antenna structures, in multiple carriers through the antenna structures, wherein the antenna structures are corresponding to different frequency bands; a baseband chip which is used for outputting a baseband signal, and configuring the antenna structures corresponding to the frequency bands of all carriers according to the frequency bands of all carriers; and a radio frequency module which is used for modulating the baseband signal on multiple carriers, transmitting the carriers to the multi-band antenna, or enabling the carriers received by the multi-band antenna to be transmitted to the baseband chip. According to the technical scheme of the invention, the method also gives consideration to a usable space of the antenna while meeting the multiband demands of the terminal, and reduces the path loss of a wireless link because a multiplexer is saved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a terminal and a multi-carrier transmission and reception method of the terminal. Background technique [0002] With the advancement of wireless communication technology and the development of smart terminals, rich multimedia content can be delivered to users on the move, and the throughput requirements of mobile terminals are also increasing. In order to provide higher data rates to mobile users, the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) proposed Carrier Aggregation (CarrierAggregation, referred to as for CA) technology. Carrier aggregation technology can provide greater bandwidth for user equipment with corresponding capabilities, and increase the peak rate of UE. [0003] However, while carrier aggregation expands bandwidth and improves spectrum utilization, it also brings problems of increased wireless link path loss a...
