Description
Technical Field
The present disclosure relates to the field of communications, and in particular, to a method and a dynamic spectrum sharing base station for a compatible terminal.
Background
With the development of 5G technology and the continuous increase of 5G service demand on 5G spectrum resources, dynamic spectrum sharing between 4G/5G is realized through DSS (Dynamic Spectrum Sharing ) technology, the respective flow demands of 4G/5G users can be met on limited spectrum resources, and the optimal performance is provided for 4G and 5G devices by utilizing the dynamic allocation of the spectrum.
Disclosure of Invention
The inventors have noted that in the related art, in order to reduce channel and signal collision between an LTE (Long Term Evolution ) terminal and an NR (New Radio, new air interface) terminal at a bandwidth of 40M, the DSS divides the 40M bandwidth into a first BWP (Band WIDTH PART ) and a second BWP, BWP1 and BWP2, wherein BWP1 resides only in the NR terminal and BWP2 is shared by the NR terminal and the LTE terminal. Further, the NR SSB (Synchronization Signal Block ) signal is placed in BWP1, as shown in FIG. 1. In fig. 1, an NR PDCCH (Physical Downlink Control Channel ) 1 is provided in BWP1, an LTE CRS (CELL REFERENCE SIGNAL ) 2 and an LTE PDCCH 3 are provided in BWP2, and an NR SSB 4 is provided in BWP 1. This has no effect on NR terminals with a bandwidth of 40M.

Fig. 2 is a flow chart of a method for a compatible terminal according to an embodiment of the present disclosure. In some embodiments, the following method flow for compatible terminals is performed by a DSS base station.
In step 201, the number of resident terminals in BWP1 in the DSS band and the new air interface NR traffic are detected.
BWP1 is only used for camping on an NR terminal, the bandwidth of which is the same as that of BWP1, and a first synchronization signal block SSB1 for reception by the camping on NR terminal is configured in BWP 1.
For example, the bandwidth of the NR terminal and the bandwidth of BWP1 are both 20M.
In some embodiments, the NR traffic is the occupancy of PRBs (Physical Resource Block, physical resource blocks).
In step 202, if the number of resident terminals in BWP1 is greater than the first preset threshold, or the NR traffic volume in BWP1 is greater than the second preset threshold, the partially resident NR terminals in BWP1 are migrated to the second bandwidth portion BWP2 in the DSS band.
BWP2 is a shared frequency band of the NR terminal and the long term evolution LTE terminal, and the bandwidths of BWP2 and BWP1 are the same.
For example, the bandwidths of BWP2 and BWP1 are each 20M.
In step 203, a second synchronization signal block SSB2 in BWP2 is turned on, wherein the periods of SSB1 and SSB2 are the same and staggered in time so that the NR terminal migrating into BWP2 receives SSB2.
In some embodiments, SSB1 and SSB2 are staggered by 1/n of the period of SSB1 or SSB2, n is a natural number, e.g., the period of SSB1 or SSB2 is T, then SSB1 and SSB2 are staggered by T/2, T/3, T/4, etc. Or the SSB1 and SSB2 are staggered by a time granularity of milliseconds, for example, staggered by 1ms, 2ms, 3ms, 4ms, etc.
For example, the periods of SSB1 and SSB2 are each 20ms, and the times of staggering SSB1 and SSB2 are 10ms.
As shown in fig. 3, SSB1 is turned on in BWP1 and SSB2 is turned on in BWP2, respectively. The periods of SSB1 and SSB2 are the same and are staggered in time as shown in fig. 4.
In the method for compatible terminals provided in the foregoing embodiments of the present disclosure, when the NR terminal with a bandwidth of 20M in BWP1 has increased residency or becomes larger in NR traffic, the DSS base station with a bandwidth of 40M migrates a portion of the NR terminals into the BWP2 band, the DSS base station starts the SSB2 signal, and the migrated NR terminals receive the SSB2 signal in a period of 20ms, thereby making full use of a portion of the BWP2 resources.
Fig. 5 is a flow chart of a method for a compatible terminal according to another embodiment of the present disclosure. In some embodiments, the following method flow for compatible terminals is performed by a DSS base station.
In step 501, the number of resident terminals in BWP1 in the DSS band and the new air interface NR traffic are detected.
BWP1 is only used for camping on an NR terminal, the bandwidth of which is the same as that of BWP1, and a first synchronization signal block SSB1 for reception by the camping on NR terminal is configured in BWP 1.
For example, the bandwidth of the NR terminal and the bandwidth of BWP1 are both 20M.
In some embodiments, the NR traffic is the occupancy of PRBs.
In step 502, it is determined whether the number of resident terminals in BWP1 is greater than a first preset threshold, or whether the NR traffic in BWP1 is greater than a second preset threshold.
If the number of resident terminals in BWP1 is greater than the first preset threshold, or the NR traffic in BWP1 is greater than the second preset threshold, step 503 is executed; if the number of resident terminals in BWP1 is smaller than the first preset threshold, or the NR traffic in BWP1 is smaller than the second preset threshold, step 505 is performed.
For example, the first preset threshold is 400 and the second preset threshold is 70%.
At step 503, the partially resident NR terminal in BWP1 is migrated to the second bandwidth portion BWP2 in the DSS band.
BWP2 is a shared frequency band of the NR terminal and the long term evolution LTE terminal, and the bandwidths of BWP2 and BWP1 are the same.
For example, the bandwidths of BWP2 and BWP1 are each 20M.
In step 504, a second synchronization signal block SSB2 in BWP2 is turned on, wherein the periods of SSB1 and SSB2 are the same and staggered in time so that the NR terminal migrating into BWP2 receives SSB2.
In some embodiments, SSB1 and SSB2 are staggered by 1/n of the period of SSB1 or SSB2, n is a natural number, e.g., the period of SSB1 or SSB2 is T, then SSB1 and SSB2 are staggered by T/2, T/3, T/4, etc. Or the SSB1 and SSB2 are staggered by a time granularity of milliseconds, for example, staggered by 1ms, 2ms, 3ms, 4ms, etc.
For example, the periods of SSB1 and SSB2 are each 20ms, and the times of staggering SSB1 and SSB2 are 10ms.
At step 505, the NR terminals residing in BWP2 are migrated to BWP1.
In step 506, the second synchronization signal block SSB2 in BWP2 is turned off.
When the residence of NR terminal in BWP1 band is reduced or the NR traffic is reduced, DSS base station transfers NR terminal in BWP2 band back into BWP1, DSS base station closes SSB2 signal, and transferred NR terminal receives SSB1 signal, so as to reduce influence of NR traffic on LTE traffic.

For example, the periods of SSB1 and SSB2 are each 20ms, and the times of staggering SSB1 and SSB2 are 10ms.
In the DSS base station for compatible terminals provided in the foregoing embodiments of the present disclosure, when the NR terminal residence with a bandwidth of 20M in BWP1 increases or the NR traffic volume becomes large, the DSS base station with a bandwidth of 40M shifts a part of the NR terminals into the BWP2 band, the DSS base station starts the SSB2 signal, and the migrated NR terminals receive the SSB2 signal with a period of 20ms, thereby making it possible to fully utilize part of the BWP2 resources.
