Description

Communication system

Technical Field

The utility model relates to the field of communication technology, especially, relate to a communication system.

Background

The conventional user terminal, i.e. a mobile phone, is required to be portable, and therefore, the size of the conventional user terminal cannot be too large. Thus, the number of antennas and devices carried by the antenna is limited, and the signal transceiving capacity and the data processing capacity of the antenna are limited.

Applications such as VR (virtual reality), AR (augmented reality) and the like require that a terminal has stronger signal transceiving and data processing capabilities, and the terminal needs to have stronger multi-antenna processing capabilities.

Meanwhile, low-power-consumption devices such as earphones, a bracelet, a touch acquisition device and a medical detector embedded into the body of the user can be distributed on each part of the user, and the shielding of the user of the low-power-consumption devices can block the connection between the user and a mobile phone, so that the quality of a wireless channel is deteriorated. This may increase the communication power consumption of the terminal and thus reduce the service time of the device, or may affect the communication quality, which may ultimately hinder the transmission of data generated by the terminal over the internet.

In addition, at the present stage, the mobile phone is a main carrier for signal transceiving and data processing of the user side, and various wearable devices such as watches, bracelets, glasses, belts and the like can be expanded by taking the mobile phone as a center. Here, these wearable devices are all centered around the mobile phone, that is, the wearable device communicates with the mobile phone, and the mobile phone communicates with the base station.

Among them, there are also communication terminal products in which a communication module is mounted in a wristwatch or glasses. However, these communication terminal products are smaller in size and cannot provide stronger signal transceiving capability and data processing capability.

As can be seen from the above, in the prior art and the prior art, the transceiving and processing of the user-side signal are mainly performed in small, portable, and observable devices such as a mobile phone, a watch, and glasses. Due to the small size, the number of antennas and devices which can be carried by the antenna is limited, so that the signal transceiving capacity and the data processing capacity of the antenna are limited. In the face of the communication scene of high-speed wireless communication and a large number of low-power-consumption accessory equipment in the future, the existing mode of using a mobile phone as communication center equipment cannot meet the requirement.
