Embodiment 1

[0089] In this embodiment, the process of pilot frequency measurement may specifically include the following steps:

[0090]Step 1: The network side determines the port configuration of the pilot frequency measurement and the time domain configuration of the corresponding port configuration, and notifies the corresponding port configuration information and time domain configuration information to the receiving end;

[0091] Specifically, in this embodiment, it is determined to use such as figure 2 In the port configuration shown, there are 16 ports in total, and the 7 ports (ports 1, 2, 3, 4, 5, 9, 13) in the shaded part are ports for sending pilot signals, and the 9 ports in the non-shaded part ports (ports 6, 7, 8, 10, 11, 12, 14, 15, and 16) are ports that do not transmit pilot signals. That is to say, in this embodiment, the first row port and the first column port are used to send pilot information.

[0092] The port configuration information of the above port configur...

Embodiment 2

[0103] In this embodiment, the process of pilot frequency measurement may specifically include the following steps:

[0104] Step 1: The network side determines the port configuration of the pilot frequency measurement and the time domain configuration of the corresponding port configuration, and notifies the corresponding port configuration information and time domain configuration information to the receiving end;

[0105] Specifically, in this embodiment, it is determined to use such as Figure 4 In the port configuration shown, there are 16 ports in total, and the 10 ports in the shaded part (ports 1, 2, 3, 4, 5, 8, 9, 12, 13, 16) are ports for sending pilot signals , the 6 ports (ports 6, 7, 10, 11, 14, and 15) in the non-shaded part are ports that do not send pilot signals. That is to say, in this embodiment, the ports in the first row, the ports in the first column, and the ports in the fourth column are used to send pilot information.

[0106] In this embodiment, an ...

Embodiment 3

[0115] In this embodiment, the process of pilot frequency measurement may specifically include the following steps:

[0116] Step 1: The transmitting end determines the port configuration and time domain configuration of the pilot measurement according to the preset port configuration. Since the port configuration information is preset, there is no need to notify the receiving end of signaling. The transmitting end only needs to send the time domain configuration information notify the receiver;

[0117] Specifically, in this embodiment, it is determined to use such as Figure 5 shown in the port configuration, Figure 5 There are four kinds of port configurations, the first port configuration is the same as figure 1 The same, that is, the ports in the first row (ports 1, 2, 3, 4) and the ports in the first column (ports 1, 5, 9, 13) are used to send pilot information; the second port is configured to use the second column The ports (ports 2, 6, 10, 14) and the ports in the...

Abstract

A method for measuring pilot is disclosed in the present invention. The method comprises the steps of: a receiving end determining the port configuration for measuring pilot; the receiving end receiving the pilot signal using the port configuration, and estimating the obtained channel information. Accordingly, a receiving end for measuring pilot is also disclosed in the present invention. Even if the number of antenna ports increases rapidly, a part of the ports selected therein as required can be still configured to the ports for transmitting the pilot signal. Without limiting the number of the ports for transmitting the pilot signal, the problem of the pilot configuration in the case that the number of antenna ports increases rapidly can be solved.

Description

technical field [0001] The invention relates to a three-dimensional (3D) beam forming technology, in particular to a pilot frequency measurement method and device. Background technique [0002] 3D beamforming technology is an important technology for improving cell resource utilization and solving inter-cell interference. The basic starting point of 3D beamforming is to use both horizontal and vertical beams to achieve higher space Reusability, and improve system throughput. [0003] In order to realize 3D beamforming, multiple groups of antennas are usually required to be used together, which involves the problem of pilot design under complex antenna configurations. At present, in the channel measurement in R10, different specific antenna port numbers adopt different pilot configurations, and support four pilot configurations of 1-port transmission, 2-port transmission, 4-port transmission, and 8-port transmission, and there are corresponding Pilot transmission pattern. ...
