Abstract

The invention relates to the communication field, in particular to a heterogeneous network used for beam training and tracking. The heterogeneous network includes a first base station, a group of second base stations and a mobile device, the first base station communicates with the mobile device through wireless signals, and communicates with the group of second base stations through a wireless access network, The mobile device communicates with the group of second base stations through millimeter wave signals, and the first base station determines a target second base station to connect with the mobile device according to the location of the mobile device and obtains a first beam angle information, and sends the second base station to the mobile device. Sending beam angle information to the mobile device and triggering the mobile device to perform beam training with the target second base station according to the received first beam angle information, so as to reduce the calculation load of beamforming and maintain a robust link between the base station and the user device connect.

Description

technical field [0001] The present invention relates to the communication field, in particular to a heterogeneous network, mobile device and method for beam training and tracking. Background technique [0002] In the prior art, beamforming is an optimal beam direction determined and formed by multiple antenna units, and a maximum information rate can be transmitted according to the optimal beam direction. However, in the prior art, mmWave beamforming based on estimated channel state information has high computational load and large overhead. In addition, it is often necessary to establish and maintain a robust link connection between the base station and the user equipment in a heterogeneous network. Contents of the invention [0003] In view of the above, it is necessary to provide a heterogeneous network, a mobile device and method for beam training and tracking to reduce the computational load of beamforming and maintain a robust link connection between the base statio...
