Embodiment 1

[0130] Please refer to figure 1 , figure 1 It is a schematic flow chart of a beamforming training method according to Embodiment 1 of the present invention. The beamforming training method is applied to a terminal, including:

[0131] Step 11: The terminal determines the number of uplink training beams that can be transmitted to the base station, where the number is M, M is a positive integer, and the number is the number of all uplink training beams that the terminal can support, or, is the number of uplink training beams that the terminal can transmit in the current uplink beam training phase;

[0132] Wherein, M is usually a positive integer greater than 1.

[0133] Step 12: The terminal transmits the M uplink training beams to the base station, so that the base station can select an optimal uplink training beam from the uplink training beams, and select an optimal uplink training beam according to the optimal uplink training beam The target uplink transmission beam co...

Embodiment 2

[0138] Please refer to figure 2 , figure 2 It is a schematic flow chart of the beamforming training method in Embodiment 2 of the present invention, the beamforming training method is applied to the terminal, including:

[0139] Step 21: The terminal determines the number of uplink training beams that can be transmitted to the base station, where the number is the number of all uplink training beams that the terminal can support, the number is M, and M is a positive integer, the The number of all uplink training beams that the terminal can support is one of the capabilities of the terminal;

[0140] Step 22: The terminal determines the serial number of the uplink training beam according to the number of the uplink training beam;

[0141]Step 23: The terminal reports the number of the uplink training beams to the base station, so that the base station determines the number of the uplink training beams.

[0142] Step 24: The terminal transmits the M uplink training beams to...

Embodiment 3

[0156] Please refer to image 3 , image 3 It is a schematic flow chart of the beamforming training method in Embodiment 3 of the present invention. The beamforming training method is applied to the terminal, including:

[0157] Step 31: The terminal determines the number of uplink training beams that can be transmitted to the base station, where the number is the number of uplink training beams that the terminal can transmit in the current uplink beam training phase, and the number is M, where M is positive integer;

[0158] The number of uplink training beams that the terminal can transmit in the current uplink beam training phase may be determined by the following factors:

[0159] (1) Determined according to the resource configuration in the current uplink beam training phase and / or the beam switching capability of the terminal; wherein, the beam switching capability of the terminal is one of the capabilities of the terminal;

[0160] or

[0161] (2) agreed upon by the...

Abstract

Provided are a beamforming training method, a terminal, and a base station. The beamforming training method comprises: a terminal determines the quantity of uplink training beams that can be transmitted to a base station, the quantity being the quantity of all uplink training beams that can be supported by the terminal, and the quantity being M, which is a positive integer, or the quantity being the quantity of uplink training beams that the terminal can transmit in a current uplink beam training phase; the terminal transmits the M uplink training beams to the base station, so that the base station can select an optimal uplink training beam from the uplink training beams, obtain a target uplink transmit beam corresponding to the terminal according to the optimal uplink training beam, and determine the serial number of the target uplink transmit beam.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a beamforming training method, a terminal and a base station. Background technique [0002] In view of the important role of MIMO (Multiple-Input Multiple-Output) technology in improving the peak rate and system spectrum utilization, LTE (Long Term Evolution, Long Term Evolution) / LTE-A (LTE-Advanced) and other wireless access All input technical standards are built on the basis of MIMO+OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) technology. The performance gain of MIMO technology comes from the spatial freedom obtained by multi-antenna systems. Therefore, one of the most important evolution directions of MIMO technology in the standardization development process is the expansion of dimensions. In LTErel-8, MIMO transmission of up to 4 layers can be supported. Rel-9 focuses on enhancing MU-MIMO technology. TM (Tran...
