Abstract
The invention provides a scheduling method combined with system user information for time division (TD) LTE (long term evolution) 8-channel equipment. The scheduling method comprises the following steps: setting a parameter Ut by using a base station scheduler, wherein the Ut represents the number of users which are serviced by a system in a TD mode; defining two mapping schemes: a fixed 8-channle to 2-port mapping mode and a 8-channle to 2-port mapping mode for different users; calculating UC which is the number of users served at the current moment by the base station; if Uc>Ut, sending data by a base station in a fixed 8-channle to 2-port mapping mode through a control channel and a data channel requiring 2 ports for transmitting; otherwise, scheduling a user for sending data at the current moment by the base station and sending data in the 8-channle to 2-port mapping mode for the current user by the control channel and the data channel requiring 2 ports for transmitting. By using the method, the system user status information is introduced into the scheduling process of the base station, thereby more effectively utilizing characteristics of the 8 channel equipment and improving the performances of control channels and data channels of the system.
Description
Technical field
The present invention relates to the communication technology, relate in particular to a kind of TD LTE 8 channel unit dispatching methods of coupling system user profile.
Background technology
LTE (Long Term Evolution, Long Term Evolution) project is the evolution of 3G, start from 2004 3GPP (The 3rd Generation Partnership Project, third generation partner program) the Toronto meeting.LTE also generically is called 3.9G, has the data download capabilities of 100Mbps, is considered the mainstream technology to 4G evolution from 3G.LTE can be divided into two kinds of TDD (Time Division Duplexing, time division duplex) and FDD (Frequency DivisionDuplexing, Frequency Division Duplexing (FDD)) according to duplex mode.Wherein, the LTE of TDD version is called TD LTE again.
For using the wave beam forming technology, product adopts the form of 8 antennas in the TD LTE system.But, only support 2 ports and 4 ports to send for the data channel of control channel and the transmission of non-wave beam forming.Therefore, how to utilize 8 antennas to realize that the mapping of 2 ports or 4 ports is one of difficult points of TD LTE system.
Summary of the invention
The purpose of this invention is to provide a kind of TD LTE 8 channel unit dispatching methods of coupling system user profile, it can effectively utilize 8 antennas to realize the mapping of 2 ports.
For achieving the above object, the present invention adopts following technical scheme:
A kind of TD LTE 8 channel unit dispatching methods of coupling system user profile comprise:
Step 1: base station dispatcher setup parameter Ut, the number of users of representing TD LTE system to serve in the mode of time-division, wherein the time-division represents that each scheduling of base station constantly only dispatches a user and carry out transfer of data;
Step 2: the scheme that defines two kinds of 8 days alignment 2 port mapping: a kind of mapping mode that is 8 passages fixed to 2 ports; A kind of is at 8 passages of the different user mapping mode to 2 ports;
Step 3: the base station is calculated the current time service-user and is counted Uc;
Step 4: if Uc＞Ut, then the base station adopts 8 fixing passages to carry out control channel and need carry out data with the data channel of 2 port transmission sending to the mapping mode of 2 ports; Otherwise user of base station current time scheduling carries out the data transmission, and control channel and the data channel that needs 2 ports to send adopt 8 passages at the active user to carry out the data transmission to the mapping mode of 2 ports.
Further, described 8 fixing passages are broadcasting tax power mode to the mapping mode of 2 ports.
Further, described 8 passages at different user are the tax power mode of decomposing based on SVD to the mapping mode of 2 ports.
The TD LTE 8 channel unit dispatching methods of coupling system user profile provided by the invention can effectively utilize 8 antennas to realize the mapping of 2 ports.

Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
As shown in Figure 1, the invention provides a kind of TD LTE 8 channel unit dispatching methods of coupling system user profile, comprising:
Step 1: base station dispatcher setup parameter Ut, the number of users of representing TD LTE system to serve in the mode of time-division, wherein the time-division represents that each scheduling of base station constantly only dispatches a user and carry out transfer of data;
Step 2: the scheme that defines two kinds of 8 days alignment 2 port mapping: a kind of mapping mode that is 8 passages fixed to 2 ports; A kind of is at 8 passages of the different user mapping mode to 2 ports;
Wherein Gu Ding mapping mode refers to adopt 8 identical passages to 2 port mapping modes to all users, as broadcasting tax power mode; Mapping mode at different user refers to that to different user channel condition difference 8 passages that design separately are to 2 port mapping modes, as the tax power mode of decomposing based on SVD (Singular valuedecomposition, singular value decomposition).
Step 3: the base station is calculated the current time service-user and is counted Uc;
Step 4: if Uc＞Ut, then the base station adopts 8 fixing passages to carry out control channel and need carry out data with the data channel of 2 port transmission sending to the mapping mode of 2 ports; Otherwise user of base station current time scheduling carries out the data transmission, and control channel and the data channel that needs 2 ports to send adopt 8 passages at the active user to carry out the data transmission to the mapping mode of 2 ports.
The present invention has been incorporated into the system service user state information in the base station scheduling process, has more effectively utilized 8 channel unit characteristics, has improved TD LTE system's control channel and data channel performance.Thereby dispatching method of the present invention can effectively utilize 8 antennas to realize the mapping of 2 ports.
The above is preferred embodiment of the present invention only, is not to be used for limiting practical range of the present invention; If do not break away from the spirit and scope of the present invention, the present invention is made amendment or is equal to replacement, all should be encompassed in the middle of the protection range of claim of the present invention.
