Embodiment 1

[0107] Such as Figure 4 As shown, the processing method of the downlink beam training signal provided by Embodiment 1 of the present invention can be applied to the terminal side, and the processing method includes:

[0108] Step 41: Using different downlink receiving beams to receive the downlink receiving beam training signals sent by the base station with a preset number of groups;

[0109] Step 42: Obtain a first target training signal according to the downlink receiving beam training signal, and obtain a downlink receiving beam for receiving downlink data sent by the base station according to the first target training signal.

[0110] The purpose of using different downlink receiving beams to receive the downlink receiving beam training signal sent by the base station is to compare and select a better downlink receiving beam.

[0111] The scenario in which the terminal executes the processing method may be when it is powered on, or when it enters a signal coverage area ...

Embodiment 2

[0138] Such as Figure 5 As shown, the processing method of the downlink beam training signal provided by Embodiment 2 of the present invention can be applied to the base station side, and the processing method includes:

[0139] Step 51: Send a preset number of downlink receiving beam training signals to the terminal, so that the terminal can obtain a downlink receiving beam for receiving downlink data according to the downlink receiving beam training signal.

[0140] Wherein, the base station may send a signal in a polling direction.

[0141] Considering that the preset number of groups can be one group or multiple groups, in the embodiment of the present invention, the step of sending downlink reception beam training signals of the preset number of groups to the terminal includes: sending a One or more groups of downlink receiving beam training signals, and the downlink sending beams of the downlink receiving beam training signals of the same group are the same, and the do...

Embodiment 3

[0171] Such as Figure 8 As shown, the terminal provided by Embodiment 3 of the present invention includes:

[0172] The first receiving module 81 is configured to use different downlink receiving beams to receive downlink receiving beam training signals of a preset number of groups sent by the base station;

[0173] The first processing module 82 is configured to obtain a first target training signal according to the downlink receiving beam training signal, and obtain a downlink receiving beam for receiving downlink data sent by the base station according to the first target training signal.

[0174] The purpose of using different downlink receiving beams to receive the downlink receiving beam training signal sent by the base station is to compare and select a better downlink receiving beam.

[0175] The downlink receiving beam can be understood as a combination of downlink receiving weights.

[0176] Considering that the preset number of groups can be one group or multiple...

Abstract

The invention provides a processing method of a downlink beam training signal and a terminal. The processing method of the downlink beam training signal comprises the steps of using different downlinkreceiving beams to receive a preset number sets of downlink receiving beam training signals sent by a base station; and acquiring a first target training signal according to the downlink receiving beam training signals, and acquiring a downlink receiving beam for receiving downlink data sent by the base station according to the first target training signal. According to the scheme provided by theinvention, the different downlink receiving beams are used for receiving the downlink receiving beam training signals sent by the base station, and the downlink receiving beam for receiving downlinkdata sent by the base station is acquired according to the received downlink receiving beam training signal, so that the condition that the terminal receives data correctly can be ensured, and training of the downlink receiving beam is achieved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and terminal for processing a downlink beam training signal. Background technique [0002] Wireless access technology standards such as LTE (Long Term Evolution, long-term evolution technology) / LTE-A (LTE-Advanced, an upgraded version of long-term evolution technology) are based on MIMO (Multiple-Input Multiple-Output, multiple-input multiple-output) + OFDM ( Orthogonal Frequency Division Multiplexing (Orthogonal Frequency Division Multiplexing) technology is built on the basis. Among them, MIMO technology obtains a high degree of spatial freedom by using multiple antennas at the transmitting end and receiving end at the same time, thereby improving the peak data transmission rate and system spectrum utilization of the system, and greatly improving the system performance gain. [0003] One of the most important evolution directions in the standardization ...
