The LTE (Long Term Evolution) cell has more users, the service of the cell is busy sometimes, some services are idle, the cell goes through a Multi-user pairing process based on a 3D-MIMO (Three-Dimension Multiple-Input Multiple-Output) technology when the cell is busy, more pairing layer gains are possessed, and the cell throughput is improved. When a cell is idle, the original LTE procedure is followed, that is, inter-Mode and intra-Mode adaptation of TM3/8(Transmission Mode 3/8) is realized according to user spectrum efficiency.
As shown in fig. 1, when a 3D-MIMO base station operates a downlink multi-user pairing Mode, a downlink Transmission Mode is simultaneously fixed to TM7(Transmission Mode 7) single-stream beamforming. For a plurality of users in a cell, a Media Access Control (MAC) generates a candidate user set based on a fast polling algorithm, and reports the spectrum efficiency of the candidate user to a Field Programmable Gate Array (FPGA) module. And the FPGA calculates the user participation pairing capable of maximizing the user pairing throughput after pairing by adopting a greedy algorithm, finally selects N users, and feeds back the paired user set to the MAC, wherein N is the number of paired layers. And the MAC preferentially allocates resources according to the N users in the provided paired user set and then allocates resources to the non-paired users, so that the throughput of the whole cell is improved as much as possible.
When the existing 3D-MIMO base station operates a downlink multi-user pairing mode, a transmission mode is fixed to TM7 single-stream beamforming, even if the channel condition of a user is good, other transmission modes cannot be used, system resources cannot be fully utilized in real time, and the throughput of a cell is influenced.

Detailed Description
The following further describes embodiments of the present invention with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Fig. 2 is a flowchart illustrating a method for processing multi-user pairing after mode switching according to this embodiment, where the method includes:
s201, counting the utilization rate of a Physical Resource Block (PRB), and switching the transmission mode of the user in the first transmission mode to the second transmission mode if the utilization rate is judged to be larger than a first threshold.
Specifically, the MAC counts the current PRB to obtain the utilization rate of the PRB. The judgment of the utilization rate of the PRB is judged through two threshold values: a low threshold and a high threshold, as shown in fig. 3. Wherein the first threshold is a high threshold.
The first transmission mode and the second transmission mode are two different data transmission modes. When the existing 3D-MIMO base station operates a downlink multi-user pairing mode, a transmission mode is fixed to TM7 single-stream beamforming, even if the user channel condition is good, TM3 or TM8 double streams cannot be used, and the stream number gain of a cell is limited; the switching of TM3, TM8 double-current and TM8 single-current beam forming modes can not be carried out in real time according to the channel state and the PRB utilization rate of the cell, and the system resources can not be fully utilized in real time to improve the throughput of the cell; the old users always in TM3/TM8 will not be switched to TM7 single-stream beamforming to participate in the subsequent user pairing process, which will limit the multi-user gain when the paired users select, and affect the cell throughput.
In this embodiment, the first transmission mode is TM3, the second transmission mode is TM8, and other transmission modes may be adopted.
S202, adding users with SINR (Signal to Interference plus Noise Ratio) larger than a Signal to Interference plus Noise Ratio threshold into a pairing candidate set, and determining the number of pairing layers and at least one pairing user according to the pairing candidate set.
The SINR threshold is a preset threshold value used for judging the SINR of the user.
And the pairing candidate set is a set of the users to be paired after the preliminary screening, each user in the pairing candidate set is processed by a greedy algorithm, and the users to be paired are further screened to obtain the users to be paired finally.
The number of pairing layers is the number of users who are finally paired.
Specifically, the FPGA calculates the number of matched layers and returns the calculated number to the MAC, and the MAC judges the number of matched layers according to the result returned by the FPGA so as to determine whether to enter a matched scheduling process.
And S203, if the matching layer number is judged to be larger than the second threshold, matching and scheduling the at least one matched user.
The second threshold is a preset threshold value for judging the number of the paired layers.
Specifically, referring to fig. 3, after counting the PRB utilization by the MAC, when the PRB utilization is higher than the upper threshold, the MAC controls the TM3 user to switch to TM8, the TM8 user cannot switch to TM3, and the new access user is set to TM 8; then MAC selects users whose SINR is larger than the SINR threshold to generate a matching candidate set, and reports the matching candidate set to FPGA; the FPGA adopts a greedy algorithm to N users in the pairing candidate set, and a user i capable of maximizing the cell throughput is selected in a traversing mode to be added into the pairable user set until the cell throughput can not be increased any more, the total number N of pairable users is countedpI.e. the maximum number of pairable layers, and apply NpAnd sending the data to the MAC, and performing pairing scheduling on the at least one paired user by the MAC.
In this embodiment, the utilization rate of the PRB is counted, when the utilization rate is greater than the first threshold, the transmission mode is switched, and when the number of paired layers is greater than the second threshold, the users are scheduled in a paired manner, so that the resource utilization rate and throughput of the cell can be improved, and the communication rate of the users is improved.
Further, on the basis of the above method embodiment, the pairing schedule includes:
and controlling the double-flow user in the second transmission mode to be switched into a single-flow user in the second transmission mode, and performing multi-user pairing scheduling and resource allocation.
And ensuring that the unsuccessfully paired users reach the preset bit rate, and averagely allocating resources to the unsuccessfully paired users.
For example, referring to fig. 3, when the MAC determines that the number of pairing layers is higher than the high threshold, pairing and scheduling are performed on paired users, specifically: the MAC controls TM8 double-flow users to be forcibly switched to TM8 single-flow users to participate in multi-user pairing scheduling, and resources are evenly distributed to users which are not successfully paired while the Minimum Bit Rate (MinBR) is kept; when the number of matched layers calculated by the FPGA is lower than a low threshold, a matching result is not referred to, the MAC does not perform matching scheduling, and each user judges whether TM8 double flow or single flow is used according to the frequency spectrum efficiency; and when the number of the pairing layers output by the pairing module is between the high threshold and the low threshold, maintaining the pairing strategy at the previous moment unchanged.
In the prior art, pairing scheduling is performed based on a TM7 single stream, a single user can only perform a single stream, and the user communication rate is low, in this embodiment, TM3/8 single/double stream switching is realized, and an MAC can perform both single-user single stream and single-user double stream adaptive scheduling, thereby improving the user communication rate; meanwhile, according to the actual situation on site, the high-low threshold of the PRB utilization rate and the high-low threshold of the pairing layer number can be flexibly configured, and the utilization rate of the cell resources is improved; in addition, in the prior art, a TM7 single stream is fixed, and a user always in the TM3 does not participate in pairing, and the method provided by this embodiment can allow the user to participate in a pairing process, thereby increasing a multi-user gain during pairing selection.
The method for processing multi-user pairing after mode switching based on the PRB utilization ratio provided in this embodiment solves the problem that only fixed TM7 single-stream pairing can be adopted due to low user throughput found in the current external field test, and can form a mechanism for coexistence of TM3/8 single-stream and double-stream, various switching between modes and in-mode and multi-user pairing, and improve the air interface rate.
Further, on the basis of the above method embodiment, S201 specifically includes:
counting the utilization rate of PRB, if the utilization rate is judged to be larger than a first threshold, switching the transmission mode of the user in the first transmission mode to a second transmission mode, prohibiting the transmission mode of the user in the second transmission mode from being switched to the first transmission mode, and setting the transmission mode of a newly accessed user to be the second transmission mode.
For example, referring to fig. 3, after counting the PRB utilization by the MAC, when the PRB utilization is higher than the upper threshold, the TM3 user controlled by the MAC may be switched to TM8, the TM8 user may not switch to TM3, and the new access user is set to TM8, which can ensure that users of the current network all use TM8 capable of improving cell throughput.
Further, on the basis of the above embodiment of the method, the method further comprises:
and S204, if the utilization rate is judged to be smaller than a third threshold, controlling the user in the first transmission mode and the user in the second transmission mode to perform the mode self-adaptive switching between the first transmission mode and the second transmission mode.
Wherein the third threshold corresponds to the low threshold of fig. 3.
For example, referring to fig. 3, when the MAC statistics PRB utilization is lower than the low threshold, adaptive switching between TM3/8 modes of the original LTE is performed, that is, according to the user spectrum efficiency, adaptation between TM3/8 modes and within modes is implemented, and the MAC does not report a paired user candidate set to the FPGA.
The existing 3d mimo base station only has a fixed TM7 or TM8 pairing procedure, and this embodiment realizes coexistence of adaptive switching between TM3/8 modes and TM8 multi-user pairing procedures, and mutual state conversion, thereby improving resource utilization and user experience.
In addition, when the downlink average PRB utilization of the cell is between high and low, as shown in fig. 3, the mode switching and scheduling policy at the previous time are maintained. For example, when the PRB utilization rate is switched from being higher than the high threshold to being between the high threshold and the low threshold, the mode switching and scheduling strategy is adopted when the PRB utilization rate is higher than the high threshold; and when the PRB utilization rate is increased from being lower than the low threshold to being between the high threshold and the low threshold, adopting a mode switching and scheduling strategy when the PRB utilization rate is lower than the low threshold.
