Embodiment 1

[0158] In the embodiment of the present invention, such as figure 2 As shown, the specific process for the terminal to perform beam management is as follows:

[0159] Step 101: The terminal sends related information of the downlink beam of the terminal to the base station, so that the base station determines a first downlink sending beam based on the related information of the downlink beam.

[0160] In the embodiment of the present invention, the specific implementation of step 101 is as follows:

[0161] The terminal receives K downlink transmission beam training signals sent by the base station based on at least one downlink reception beam among the M downlink reception beams;

[0162] determining, by the terminal, information related to downlink beams of the terminal based on received signals received by the at least one downlink receive beam;

[0163] sending, by the terminal, information related to the downlink beam to the base station;

[0164] Wherein, M and K are ...

Embodiment 2

[0207] In the embodiment of the present invention, such as figure 2 As shown, the specific process for the terminal to perform beam management is as follows:

[0208] Step 101: The terminal sends related information of the downlink beam of the terminal to the base station, so that the base station determines a first downlink sending beam based on the related information of the downlink beam.

[0209] In the embodiment of the present invention, the specific implementation of step 101 is as follows:

[0210] The terminal receives K downlink transmission beam training signals sent by the base station based on at least one downlink reception beam among the M downlink reception beams;

[0211] determining, by the terminal, information related to downlink beams of the terminal based on received signals received by the at least one downlink receive beam;

[0212] sending, by the terminal, information related to the downlink beam to the base station;

[0213] Wherein, M and K are in...

Embodiment 3

[0247] Based on the same inventive concept, in the embodiment of the present invention, such as image 3 As shown, the specific process of beam management by the base station is as follows:

[0248] Step 201: the base station receives information about downlink beams sent by the terminal.

[0249] In the embodiment of the present invention, before step 201, the method further includes:

[0250] The base station sends K downlink beam training signals to the terminal, where K is an integer greater than or equal to 1.

[0251] Specifically, the base station first receives information about its own receiving beams reported by the terminal, such as the number of receiving beams of the terminal or the number of receiving beam groups of the terminal. Then, the base station sends a downlink transmission beam training signal based on the received self-reception beam information of the terminal. Wherein, the manner in which the base station transmits the downlink beam training signal...

Abstract

The invention discloses an antenna beam management method and related equipment, which are used for solving a problem of large overhead of beam management control signaling in the existing large-scaleantenna technology. The method comprises the following steps that a terminal sends related information of a downlink beam of the terminal to a base station, so that the base station determines a first downlink transmission beam based on the related information of the downlink beam; the terminal receives notification information sent by the base station and related to the first downlink transmission beam, wherein the notification information comprises indication information of the terminal for determining at least one first downlink receiving beam; the terminal determines the at least one first downlink receiving beam based on the notification information; and the terminal receives a downlink signal based on the at least one first downlink receiving beam.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an antenna beam management method and related equipment. Background technique [0002] 1. Introduction to MIMO technology [0003] In view of the important role of MIMO technology in improving peak rate and system spectrum utilization, wireless access technology standards such as LTE (Long Term Evolution) / LTE-A (LTE-Advanced) are based on MIMO+OFDM (Orthogonal Frequency Division Multiplexing) technology built up. 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. [0004] In LTE Rel-8, up to 4 layers of MIMO transmission can be supported. Rel-9 focuses on enhancing the MU-MIMO technology. The MU-MIMO (Multi-User MIMO) transmission of TM (Transmission Mode)-8 ...
