Description
Technical Field
The present invention relates to a connection management technology in the field of communications, and in particular, to a communication processing method, apparatus, and storage medium.
Background
The LTE downlink supports the 3D-MIMO technology to multiplex the spatial dimension. Spatial multiplexing supports single-user SU-MIMO mode and multi-user MU-MIMO mode. In SU-MIMO, a TM3/8 self-adaptive transmission mode is adopted, so that the throughput and the spectral efficiency of a single user are improved; in MU-MIMO, a fixed TM8 or fixed TM7 transmission mode is adopted, and the throughput and the capacity of the whole cell are improved through multi-user space division multiplexing. In the case of multi-user pairing, mutual interference exists between UE-specific reference symbols of paired users, and the throughput and spectral efficiency of the entire cell are reduced.
However, when multiple users are paired in a 3D-MIMO system, the transmission scheme is fixed to TM7 or TM8, and the optimal orthogonality between UE-specific reference symbols of the multiple users cannot be achieved, which results in a decrease in throughput and spectral efficiency of the entire cell.

Detailed Description
The invention is described in further detail below with reference to the figures and specific examples.
The first embodiment,
An embodiment of the present invention provides a communication processing method, as shown in fig. 1, including:
step 101: acquiring the number of UE contained in a set of User Equipment (UE) participating in pairing;
step 102: judging whether the number is lower than a preset number threshold value or not;
step 103: when the number is lower than a preset number threshold value, adopting a TM8 mode to perform downlink data transmission on each UE in the set of the UE participating in pairing; and when the number is not lower than a preset number threshold value, determining to adopt a TM7 or TM8 mode for downlink data transmission based on the channel correlation of the UEs in the set of the UE participating in the pairing.
The embodiment can be applied to a network side, and particularly to a base station, and of course, the embodiment can also be arranged in a core network, analyzed by a management device in the core network, and then send a control instruction to the base station. Specifically, the mode may be set according to an actual networking situation, and is not exhaustive in this embodiment.
Before performing step 101, selecting UEs participating in pairing and forming a set of UEs participating in pairing may be included, for example:
calculating the priority of all the UE managed by the UE to obtain the user priority of each UE;
carrying out throughput estimation on at least one candidate UE group consisting of at least one UE in all the UEs to obtain the total throughput corresponding to the at least one candidate UE group;
determining a set of user equipments, UEs, participating in pairing based on the user priorities and the total throughput.
For example, when the present embodiment is applied to the 3D-MIMO base station side, the user priority may be calculated according to the PF algorithm, and the total throughput of the paired users may be estimated to determine the set of user equipments UE participating in the pairing.
That is to say, in this embodiment, first screening needs to be performed based on the number of UEs in the set, if the number of UEs is small, the TM7 mode does not need to be adopted for processing, and only the TM8 mode needs to be adopted, that is, when the number of users participating in pairing is lower than a certain threshold (the preferred value may be 4), different OCC codes and scanning identities can effectively distinguish PDSCH data downlink transmitted by different users, and at this time, the paired users are all configured in the TM8 mode.
Based on the foregoing determination, this embodiment also aims at determining the spatial isolation of the users, that is, when the number of users participating in the pairing is higher than a certain number threshold (for example, the number of users is greater than 4, there are 6 or 10 UEs in the set, or more UEs), the spatial isolation between the users is considered, and the method further includes: and acquiring the channel correlation between downlink channels of each group of UE in the set of the UE participating in pairing.
There may be many algorithms for obtaining the channel correlation, and this embodiment is not limited and is not exhaustive.
The determining to employ a TM7 or TM8 mode for downlink data transmission based on channel correlations of UEs in a set of UEs participating in pairing includes:
acquiring channel correlation between downlink channels in each group of UE in a set of UE participating in pairing;
determining a number of UE groups having a channel correlation greater than a preset correlation threshold value, determining, for each UE in the set of paired UEs, to employ TM7 or TM8 mode for downlink data transmission based on the number.
Specifically, the method comprises the following steps:
when the number of the UE groups larger than the preset correlation threshold is larger than a first threshold, adopting a TM7 mode to perform downlink data transmission aiming at each UE in the set of the UE participating in pairing;
and when the number of the UE groups larger than the preset correlation threshold value is not larger than a first threshold value, adopting a TM8 mode to perform downlink data transmission aiming at each UE in the paired UE set.
The present embodiment may be illustrated by taking PDSCH as an example, for example: when the number of the UE groups larger than the preset correlation threshold is larger than a first threshold, adopting a TM7 mode to perform PDSCH transmission aiming at each UE in the paired UE set;
and when the number of the UE groups larger than the preset correlation threshold value is not larger than a first threshold value, adopting a TM8 mode to perform PDSCH transmission aiming at each UE in the paired UE set.
It should be noted that the method for determining downlink data transmission by using TM7 or TM8 based on channel correlation provided in this embodiment may correspond to the following scenarios:
in a first scenario, judging whether channel correlation between each group of UEs is greater than a preset correlation threshold value one by one from a set of UEs participating in pairing, and if so, setting the group of UEs to adopt TM7 for downlink data transmission (specifically, PDSCH transmission);
otherwise, judging whether the number of the UE which is not greater than the preset correlation threshold value is smaller than a second threshold value, if so, adopting TM8 to perform downlink data transmission, if not, selecting the UE which is not greater than the second threshold value from the set of the UE participating in pairing, adopting TM8 to perform downlink data transmission, and adopting TM7 to perform downlink data transmission on the remaining UE.
That is, the present scenario performs configuration of transmission mode for each UE group.
It should be further noted that, when the number of UEs whose preset correlation is not greater than the preset correlation threshold is greater than the second threshold (for example, 4 UEs), the number of UEs equal to the second threshold may be selected from the set of UEs participating in pairing, the selected UEs perform downlink data transmission in the TM8 mode, and then the remaining UEs in the set of UEs participating in pairing perform downlink data transmission in the TM7 mode.
For example, there are 6 UEs in the set of UEs participating in pairing, and the second threshold is 4; selecting 4 UEs from the set of the UEs participating in the pairing to adopt a TM8 mode for carrying out PDSCH transmission; the remaining 2 UEs employ TM7 mode for PDSCH transmission.
And in a second scenario, judging whether channel correlation between each group of UEs is greater than a preset correlation threshold one by one from the set of UEs participating in pairing, and if the number of the groups greater than the correlation threshold is greater than a first threshold, setting all UEs in the set of UEs participating in pairing to adopt TM7 for downlink data transmission (specifically PDSCH transmission). The first threshold may be set according to actual conditions, for example, may be 5 groups or more. That is, when there are many UE groups with large correlation, the TM7 mode capable of distinguishing many UEs is used for transmission.
And a third scenario, judging whether the channel correlation between each group of UEs is not greater than a preset correlation threshold one by one from the paired UE sets, and if the number of the groups not greater than the correlation threshold is less than a first threshold, setting all UEs in the paired UE sets to adopt TM8 for downlink data transmission (specifically PDSCH transmission).
For example, if the channel correlation is greater than a threshold, which indicates that the spatial separation between the user groups is poor, the TM7 mode scrambled by the C-RNTI is selected for downlink PDSCH data transmission. If the channel correlation is greater than the number of a certain threshold user group and less than a certain threshold, which indicates that the spatial isolation between the user groups is better, the TM8 mode is selected for downlink PDSCH data transmission. For example, referring to the following table, it can be seen that, first, a UE combination having a channel correlation greater than a preset correlation threshold is selected, and then a transmission mode of a different UE combination is determined based on whether the channel correlation is greater than the threshold.
| UE participating in pairing | UE combination with channel correlation greater than threshold | Selection of transmission mode |
| UE1 | UE1&UE3 | TM7 |
| UE2 | UE2&UE3 | TM7 |
| UE3 | ---- | TM7 |
| UE4 | ---- | TM7 |
| UE5 | UE5&UE6 | TM7 |
| UE6 | ---- | TM7 |
| UE7 | ---- | TM7 |
Therefore, by adopting the scheme, the selection of the transmission mode can be carried out based on the number of the paired users and the correlation of the downlink channel, so that the downlink data transmission in a fixed mode is avoided, the transmission mode can be selected in a self-adaptive manner by combining the correlation of the channel, the orthogonality among the specific reference symbols of the multi-user UE is effectively improved, and the downlink spectrum efficiency and the throughput of the cell are improved.

The embodiment can be applied to a network side, and particularly to a base station, and of course, the embodiment can also be arranged in a core network, analyzed by a management device in the core network, and then send a control instruction to the base station. Specifically, the mode may be set according to an actual networking situation, and is not exhaustive in this embodiment.
The UE management unit 21 is configured to perform priority calculation for all UEs managed by the UE management unit to obtain a user priority of each UE;
carrying out throughput estimation on at least one candidate UE group consisting of at least one UE in all the UEs to obtain the total throughput corresponding to the at least one candidate UE group;
determining a set of user equipments, UEs, participating in pairing based on the user priorities and the total throughput.
For example, when the present embodiment is applied to the 3D-MIMO base station side, the user priority may be calculated according to the PF algorithm, and the total throughput of the paired users may be estimated to determine the set of user equipments UE participating in the pairing.
That is to say, in this embodiment, first screening needs to be performed based on the number of UEs in the set, if the number of UEs is small, the TM7 mode does not need to be adopted for processing, and only the TM8 mode needs to be adopted, that is, when the number of users participating in pairing is lower than a certain threshold (the preferred value may be 4), downlink data transmitted by different users in downlink can be effectively distinguished by different OCC codes and Scrambling identities, and at this time, the paired users are all configured in the TM8 mode.
Based on the foregoing determination, this embodiment also aims at determining the spatial isolation of the users, that is, when the number of users participating in the pairing is higher than a certain number threshold (for example, the number of users is greater than 4, there are 6 or 10 UEs in the set, or more UEs), the spatial isolation between the users is considered, and the method further includes: and acquiring the channel correlation between downlink channels of each group of UE in the set of the UE participating in pairing.
There may be many algorithms for obtaining the channel correlation, and this embodiment is not limited and is not exhaustive.
The communication mode management unit 22 is configured to obtain channel correlation between downlink channels in each group of UEs in the set of UEs participating in pairing; determining a number of UE groups having a channel correlation greater than a preset correlation threshold value, determining, for each UE in the set of paired UEs, to employ TM7 or TM8 mode for downlink data transmission based on the number.
Specifically, the present embodiment specifically specifies downlink data transmission by PDSCH, and the communication mode management unit 22 is used for
When the number of the UE groups larger than the preset correlation threshold is larger than a first threshold, adopting a TM7 mode to perform PDSCH transmission aiming at each UE in the paired UE set;
and when the number of the UE groups larger than the preset correlation threshold value is not larger than a first threshold value, adopting a TM8 mode to perform PDSCH transmission aiming at each UE in the paired UE set.
It should be noted that the method for determining downlink data transmission by using TM7 or TM8 based on channel correlation provided in this embodiment may correspond to the following scenarios:
in a first scenario, judging whether channel correlation between each group of UEs is greater than a preset correlation threshold value one by one from a set of UEs participating in pairing, and if so, setting the group of UEs to adopt TM7 for downlink data transmission (specifically, PDSCH transmission); otherwise, judging whether the number of the UE which is not greater than the preset correlation threshold value is smaller than a second threshold value, if so, adopting TM8 to perform downlink data transmission, if not, selecting the UE which is not greater than the second threshold value from the set of the UE participating in pairing, adopting TM8 to perform downlink data transmission, and adopting TM7 to perform downlink data transmission on the remaining UE.
That is, the present scenario performs configuration of transmission mode for each UE group.
It should be further noted that, when the number of UEs whose preset correlation is not greater than the preset correlation threshold is greater than the second threshold (for example, 4 UEs), the number of UEs equal to the second threshold may be selected from the set of UEs participating in pairing, the selected UEs perform downlink data transmission in the TM8 mode, and then the remaining UEs in the set of UEs participating in pairing perform downlink data transmission in the TM7 mode.
For example, there are 6 UEs in the set of UEs participating in pairing, and the second threshold is 4; selecting 4 UEs from the set of the UEs participating in the pairing to adopt a TM8 mode for carrying out PDSCH transmission; the remaining 2 UEs employ TM7 mode for PDSCH transmission.
And in a second scenario, judging whether channel correlation between each group of UEs is greater than a preset correlation threshold one by one from the set of UEs participating in pairing, and if the number of the groups greater than the correlation threshold is greater than a first threshold, setting all UEs in the set of UEs participating in pairing to adopt TM7 for downlink data transmission (specifically PDSCH transmission). The first threshold may be set according to actual conditions, for example, may be 5 groups or more. That is, when there are many UE groups with large correlation, the TM7 mode capable of distinguishing many UEs is used for transmission.
And a third scenario, judging whether the channel correlation between each group of UEs is not greater than a preset correlation threshold one by one from the paired UE sets, and if the number of the groups not greater than the correlation threshold is less than a first threshold, setting all UEs in the paired UE sets to adopt TM8 for downlink data transmission (specifically PDSCH transmission).
For example, if the channel correlation is greater than a threshold, which indicates that the spatial separation between the user groups is poor, the TM7 mode scrambled by the C-RNTI is selected for downlink PDSCH data transmission. If the channel correlation is greater than the number of a certain threshold user group and less than a certain threshold, which indicates that the spatial isolation between the user groups is better, the TM8 mode is selected for downlink PDSCH data transmission. For example, referring to the following table, it can be seen that, first, a UE combination having a channel correlation greater than a preset correlation threshold is selected, and then a transmission mode of a different UE combination is determined based on whether the channel correlation is greater than the threshold.
| UE participating in pairing | UE combination with channel correlation greater than threshold | Selection of transmission mode |
| UE1 | UE1&UE3 | TM7 |
| UE2 | UE2&UE3 | TM7 |
| UE3 | ---- | TM7 |
| UE4 | ---- | TM7 |
| UE5 | UE5&UE6 | TM7 |
| UE6 | ---- | TM7 |
| UE7 | ---- | TM7 |
Therefore, by adopting the scheme, the selection of the transmission mode can be carried out based on the number of the paired users and the correlation of the downlink channel, so that the downlink data transmission in a fixed mode is avoided, the transmission mode can be selected in a self-adaptive manner by combining the correlation of the channel, the orthogonality among the specific reference symbols of the multi-user UE is effectively improved, and the downlink spectrum efficiency and the throughput of the cell are improved.

The embodiment can be applied to a network side, and particularly to a base station, and of course, the embodiment can also be arranged in a core network, analyzed by a management device in the core network, and then send a control instruction to the base station. Specifically, the mode may be set according to an actual networking situation, and is not exhaustive in this embodiment.

For example, when the present embodiment is applied to the 3D-MIMO base station side, the user priority may be calculated according to the PF algorithm, and the total throughput of the paired users may be estimated to determine the set of user equipments UE participating in the pairing.
That is to say, in this embodiment, first screening needs to be performed based on the number of UEs in the set, if the number of UEs is small, the TM7 mode does not need to be adopted for processing, and only the TM8 mode needs to be adopted, that is, when the number of users participating in pairing is lower than a certain threshold (the preferred value may be 4), downlink transmission data of different users can be effectively distinguished by different OCC codes and signing identities, and at this time, the paired users are all configured in the TM8 mode.
Based on the foregoing determination, this embodiment also aims at determining the spatial isolation of the users, that is, when the number of users participating in the pairing is higher than a certain number threshold (for example, the number of users is greater than 4, there are 6 or 10 UEs in the set, or more UEs), the spatial isolation between the users is considered, and the method further includes: and acquiring the channel correlation between downlink channels of each group of UE in the set of the UE participating in pairing.

Specifically, the processor 31 is configured to perform downlink data transmission for each UE in the set of UEs participating in pairing in a TM7 mode when the number of UE groups greater than a preset correlation threshold is greater than a first threshold;
and when the number of the UE groups larger than the preset correlation threshold value is not larger than a first threshold value, adopting a TM8 mode to perform downlink data transmission aiming at each UE in the paired UE set.
It should be noted that the method for determining downlink data transmission by using TM7 or TM8 based on channel correlation provided in this embodiment may correspond to the following scenarios:

That is, the present scenario performs configuration of transmission mode for each UE group.
It should be further noted that, when the number of UEs whose preset correlation is not greater than the preset correlation threshold is greater than the second threshold (for example, 4 UEs), the number of UEs equal to the second threshold may be selected from the set of UEs participating in pairing, the selected UEs perform downlink data transmission in the TM8 mode, and then the remaining UEs in the set of UEs participating in pairing perform downlink data transmission in the TM7 mode.

If the channel correlation is greater than the number of a certain threshold user group and less than a certain threshold, which indicates that the spatial isolation between the user groups is better, the TM8 mode is selected for downlink PDSCH data transmission. For example, referring to the following table, it can be seen that, first, a UE combination having a channel correlation greater than a preset correlation threshold is selected, and then a transmission mode of a different UE combination is determined based on whether the channel correlation is greater than the threshold.
