Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description.

In all examples shown and discussed herein, any particular value should be construed as exemplary only and not as limiting. Thus, other examples of the exemplary embodiments may have different values.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

The three schemes commonly used in DSS to resolve LTE and NR conflicts have their own advantages and disadvantages.

The LTE puncturing scheme refers to puncturing reference signals for LTE. The puncturing means not transmitting corresponding information, and the LTE puncturing scheme specifically means not transmitting the reference signal of LTE on the RE (Resource Element) that should transmit the reference signal of LTE. The LTE puncturing scheme has the advantages of low implementation complexity and no impact on NR. The disadvantage is that it has an impact on LTE, and the closer to the base station, the greater the loss of LTE; the more Resource Blocks (RBs) that are punctured, the greater the LTE loss.

Fig. 1 exemplarily shows a schematic diagram of an LTE puncturing scheme. In fig. 1, a diagonal background part indicates an LTE PDCCH (Physical Downlink Control Channel), a grid background part indicates an NR PDCCH, a horizontal background part indicates resources occupied by an LTE CRS (Cell Reference Signal), and a vertical background part indicates resources occupied by an SSB (Synchronization Signal and PBCH Block). On the other hand, in the resources corresponding to the NR PDCCH, in order to reduce interference to the SSB, it is necessary to puncture the LTE CRS, that is, not transmit the LTE CRS on the REs that should transmit the LTE CRS. This portion of punctured resources is indicated in fig. 1 with a dashed box.

The NR puncturing scheme means that no corresponding signal is transmitted at REs where an NR related signal should be transmitted. Its advantages are low complexity and no influence to LTE. The disadvantage is that when NR SSB and RMSI (Remaining minimum system information) are transmitted, no information is transmitted at the LTE CRS RE position, thus having an impact on NR.

Fig. 2 exemplarily shows a diagram of an NR puncturing scheme. In fig. 2, a hatched background portion indicates LTE PDCCH, a grid background portion indicates NR PDCCH, a horizontal background portion indicates resources occupied by LTE CRS, and a vertical background portion indicates resources occupied by SSB. When the resources occupied by the SSB collide with the LTE CRS at the time of NR puncturing, the SSB is not transmitted at the colliding LTE CRS (at the resource corresponding position of the LTE CRS within the circle in fig. 2).

The implementation complexity of the M subframe scheme is moderate. The more M subframes, the smaller the influence on NR; the more M subframes, the greater the impact on LTE, which is mainly reflected in terms of rate loss and delay. Also, this scheme requires that the LTE terminal be able to recognize the M subframes. Fig. 3 exemplarily shows a configuration diagram of an M subframe.

Therefore, three basic technical schemes adopted in the DSS have advantages and disadvantages respectively, and each scheme is difficult to be suitable for complicated and variable 4G/5G scenes.

The invention carries out reconfiguration and combination based on the three schemes to form a conflict avoidance strategy set meeting the preset conditions. An embodiment of the communication configuration method of the present invention is described below with reference to fig. 4.

Fig. 4 illustrates a flow diagram of a communication configuration method according to some embodiments of the invention. As shown in fig. 4, the communication configuration method of this embodiment includes steps S402 to S406.

In step S402, the result of priority comparison of NR with LTE in the DSS base station is determined. The priorities of NR and LTE are information pre-configured by the DSS base station.

In some embodiments, an LTE/NR priority discriminator by which whether LTE priority or NR priority is set in the DSS system is configured in advance in the DSS base station.

In step S404, according to the priority comparison result, a corresponding set of collision avoidance strategies is selected.

For example, the set of conflict avoidance policies is divided into a first set of policies and a second set of policies. The first strategy set is applicable to the condition of higher LTE priority, wherein the included strategies are strategies with the influence degree on LTE lower than the preset degree; the second set of policies applies to situations where NR is of higher priority, including policies that affect NR to a lesser degree than a preset degree.

And after the conflict avoidance strategy set is determined, selecting a specific strategy from the conflict avoidance strategy set.

In step S406, a corresponding policy is selected from the determined set of collision avoidance policies according to an average occupancy ratio of NR PRBs (Physical Resource blocks) in the cell of the DSS base station.

In some embodiments, the average occupation proportion of NR PRBs of the DSS cells within a preset time period is counted. After obtaining the statistical results, the statistical results may also be divided into a plurality of levels. For example, according to a preset division threshold, the statistical result is divided into three levels, namely high, medium and low.

In some embodiments, a NR PRB average occupancy detector is preconfigured in a DSS base station for performing statistics of the average occupancy proportion of NR PRBs.

The embodiment selects the most suitable collision avoidance strategy according to the priorities of LTE and NR and the average occupation ratio of NR PRBs. Therefore, the DSS base station can flexibly configure and combine different technical schemes for different scenes, realize dynamic switching among the different technical schemes, and improve the flexibility and the resource utilization rate of DSS networking under the condition of flexibly solving the channel and signal conflicts of LTE and NR in the DSS. Therefore, the invention improves the 4G/5G user experience and reduces the DSS operation and maintenance and optimization cost.

The specific strategies provided by some embodiments of the present invention are described below by way of example.

In some embodiments, the first policy set is applicable to a case of higher LTE priority, and includes an NR puncturing policy, an NR puncturing and M subframe combining policy, and a first M subframe policy.

In the NR puncturing strategy, NR broadcast signals, reference signals, signals in control channels, and systematic signals are punctured. That is, the RE which should transmit the NR broadcast signal, the reference signal, the signal in the control channel, and the system signal does not transmit these signals.

In the strategy of combining NR punching and M sub-frames, punching is carried out on the NR non-periodic system message, namely, the message is not sent to the RE which should send the NR non-periodic system message; and configuring the subframe in which the NR broadcast signal, the reference signal, the signal in the control channel and the periodic system signal are positioned as an M subframe.

In the first M subframe strategy, subframes in which NR broadcast signals, reference signals, control channels, and system signals are located are configured as M subframes.

The influence of the three strategies, namely an NR puncturing strategy, an NR puncturing and M subframe combination strategy and a first M subframe strategy, on NR is reduced in sequence, so that a proper strategy can be selected according to the average occupation proportion of NR PRBs. An embodiment of a collision avoidance scheme selection method in the case where the priority of NR is higher than that of LTE is described below with reference to fig. 5.

FIG. 5 illustrates a flow diagram of a collision avoidance scheme selection method according to some embodiments of the invention. As shown in fig. 5, in the case where the priority of LTE is higher than that of NR, the collision avoidance scheme selecting method of this embodiment includes steps S502 to S508.

In step S502, the average occupancy ratio of NR PRBs in the cell of the DSS base station is compared with a preset low threshold and a preset high threshold.

In step S504, if the average occupancy ratio of NR PRBs in the cell of the DSS base station is lower than the preset low threshold, an NR puncturing strategy is selected.

In step S506, if the average occupation ratio of NR PRBs in the cell of the DSS base station is between the preset low threshold and the preset high threshold, an NR puncturing and M subframe combining strategy is selected.

In step S508, if the average occupancy ratio of NR PRBs in the cell of the DSS base station is higher than the preset high threshold, a first M subframe policy is selected.

By the method of the embodiment, when the average occupation proportion of the NR PRBs is low, a strategy with relatively large influence on NR can be selected; when the average occupation ratio of the NR PRBs is high, a strategy with relatively small influence on the NR is selected. Therefore, the channel and signal conflict between LTE and NR in the DSS can be relieved, and the influence on NR and LTE can be reduced as much as possible.

In some embodiments, the second policy set is applicable to the case where NR priority is higher, and includes an LTE puncturing policy, an LTE puncturing and M subframe combining policy, and a second M subframe policy.

In the LTE puncturing strategy, the reference signals of LTE are punctured on the resources occupied by the signals of all the NR channels.

In the strategy of combining LTE punching and M subframes, in a subframe where an NR (non-periodic System) message is located, a reference signal of LTE is punched, and a subframe where an NR broadcast signal, a reference signal, a signal in a control channel and a periodic system signal are located is configured as an M subframe.

In the second M subframe strategy, the subframe in which all channels and signals of NR are located is configured as an M subframe. The second M-subframe strategy uses more M-subframes than the first M-subframe strategy.

The influence of the LTE punching strategy, the LTE punching and M subframe combination strategy and the second M subframe strategy on the NR is reduced in sequence, so that a proper strategy can be selected according to the average occupation proportion of NR PRBs. An embodiment of a collision avoidance scheme selection method in the case where the priority of LTE is higher than that of NR is described below with reference to fig. 6.

FIG. 6 is a flow diagram illustrating a conflict avoidance scheme selection method according to further embodiments of the present invention. As shown in fig. 6, in the case where the priority of NR is higher than that of LTE, the collision avoidance scheme selecting method of this embodiment includes steps S602 to S608.

In step S602, the average occupancy ratio of NR PRBs in the cell of the DSS base station is compared with the preset low threshold and high threshold.

In step S604, if the average occupancy ratio of NR PRBs in the cell of the DSS base station is lower than the preset low threshold, an LTE puncturing strategy is selected.

In step S606, if the average occupied proportion of NR PRBs in the cell of the DSS base station is between the preset low threshold and the preset high threshold, the LTE puncturing and M subframe combining strategy is selected.

In step S608, if the average occupied proportion of NR PRBs in the cell of the DSS base station is higher than the preset high threshold, the second M subframe strategy is selected.

By the method of the embodiment, when the average occupation proportion of the NR PRBs is low, a strategy with relatively large influence on NR is selected; when the average occupation ratio of the NR PRBs is higher, a strategy with less influence on NR is selected, namely a strategy with more M subframe configuration. Therefore, the channel and signal conflict between LTE and NR in the DSS can be relieved, and the influence on NR and LTE can be reduced as much as possible.

The embodiment of the invention has the advantages of less modification on the network side, lower implementation complexity, small design area, easy popularization, capability of greatly improving the reliability and completeness of the DSS technical scheme, shortening the network construction period and reducing the network construction cost.
