Embodiment 1

[0127] Such as figure 1 As shown, this embodiment provides a method for selecting a user service mode under a 3D beam, and the method includes:

[0128] Step S110: compare the total number of users to be served with the total number of dispatching units;

[0129] Step S120: when the total number of users to be served is less than the total number of dispatching units, each user selects the single-user service mode;

[0130] Step S130: When the total number of users to be served is not less than the total number of scheduling units, select J user groups that meet the preset conditions to adopt the multi-user service mode; wherein, each user group includes the same time-frequency resource for downlink communication The two users to be served; the J is an integer greater than 1, and 2J is an integer not greater than the total number of users to be served;

[0131] The user service mode includes a single user service mode and a multi-user service mode;

[0132] In the single-us...

Embodiment 2

[0230] Such as image 3 As shown, the specific sending of pilot information may include:

[0231] Step S210: Determine the number N of beams for sending pilot information; wherein, N is an integer not less than 1 and not greater than the total number of ports;

[0232] Step S220: forming N pieces of pilot information; different pilot information is carried on different beams and sent by different ports;

[0233] Step S230: Carrying the N pieces of pilot information on the N beams for transmission.

[0234] The port is generally a communication interface set on the base station for sending and receiving information, and corresponds to a sending and receiving antenna in a specific implementation process. In the prior art, when sending pilot information, at first, different pilot information will be configured for each port, and the port for sending pilot information is selected; and usually all ports need to send pilot information in rare cases, so As a result, part of the co...

Embodiment 3

[0240] Such as Figure 4 As shown, this embodiment provides a device for selecting a user service mode under a 3D beam, and the device includes:

[0241] A comparing unit 110, configured to compare the total number of users to be served with the total number of scheduling units;

[0242] The first selection unit 120 is configured to select the single-user service mode for each user when the total number of users to be served is less than the total number of the scheduling unit;

[0243] The second selection unit 130 is used to select J user groups that meet the preset conditions to adopt the multi-user service mode when the total number of users to be served is not less than the total number of the scheduling units; The two users to be served for downlink communication using frequency resources; the J is an integer greater than 1, and 2J is an integer not greater than the total number of users to be served;

[0244] The user service mode includes a single user service mode a...

Abstract

The present invention discloses the user service mode selection method, the frequency information sending method and device under the 3D beam., Each user chooses a single user service mode; and when the total number of users to be served is not less than the total number of dispatching units, the J user group that meets the preset conditions adopts multi -user service mode; of whichA time -frequency resource corresponds to a beam used for communication; in multi -user service mode, one time -frequency resource is reused by air scores at least two beams used for communication.

Description

technical field [0001] The present invention relates to user service mode selection calculation in the communication field, in particular to a user service mode selection method under 3D beams, a pilot information transmission method and a device. Background technique [0002] With the continuous increase of the number of users in the cell and the increase of user communication traffic, the traditional two-dimensional (2D) antenna configuration can no longer meet the needs of users. Companies such as Qualcomm, Aran, DOCOMO, Nokia Siemens Networks and Vodafone have established Advanced Radio Interface Technologies for 4G Systems (ARTIST4G) working groups, among which cell splitting, dynamic three-dimensional (3D) precoding technology, and dynamic downtilt adjustment Key technologies such as 3D multi-antenna technology have attracted the industry's deep attention in terms of improving the total and average throughput of cell users. [0003] The 3D beamforming technology based...
