The UE may access the AMF network element through the RAN device. Specifically, when the UE accesses the AMF network element through the RAN device, the UE may access the AMF network element through a network-side device such as a base station of a 5G or later version (e.g., a 5G NR NB), or a base station in another communication system (e.g., an eNB base station).

Fig. 2 shows a flow chart of a dynamic spectrum sharing method according to an embodiment of the present disclosure. As shown in fig. 2, the dynamic spectrum sharing method is applied to a spectrum sharing base station, where the spectrum includes at least a first frequency band and a second frequency band, and may include the following steps.

In step S210, a PDCCH of LTE is configured on at least one PDCCH symbol bit of the first frequency band; and configuring PDCCH of NR on the PDCCH symbol position of the second frequency band.

In an embodiment of the disclosure, a physical downlink control channel (Physical Downlink Control Channel, PDCCH) of LTE is configured on at least one PDCCH symbol bit of a first frequency band. And the PDCCH of NR is configured on said PDCCH symbol bit of the second frequency band. The PDCCHs of LTE and NR are configured on corresponding PDCCH symbol bits of different frequency bands.

In an exemplary embodiment, the bandwidth is extended from conventional 10M bandwidth redrawn to 15M bandwidth on 800M carrier frequency. Wherein the 15M bandwidth is divided into a first frequency band with 0-10M bandwidth and a second frequency band with 10M-15M bandwidth. Each frequency band is divided into several Resource Blocks (RBs) based on the frequency domain. And each RB contains several subcarriers, typically 12 or 16. Each subcarrier spacing (SCS) is set to 15KHz. And, each subcarrier is preset with 0-13, and total 14 symbol bits. The dynamic spectrum sharing method in the embodiment of the disclosure is to design spectrum resource allocation and sharing within the spectrum resource range.

In an exemplary embodiment, PDCCH symbol bits are configured on symbol bits 0, 1. Based on this, the PDCCH of LTE is arranged on symbol bits 0, 1 of the first frequency band; the PDCCH of NR is arranged on symbol bits 0, 1 of the second frequency band.

In step S220, PDSCH of LTE and NR is configured on non-PDCCH symbol bits of the first and second frequency bands.

In an embodiment of the disclosure, physical downlink shared channels (Physical Downlink Shared Channel, PDSCH) of LTE and NR are configured on non-PDCCH symbol bits of the first and second frequency bands. Here, the non-PDCCH symbol bit is another symbol bit not allocated to PDCCH occupation among symbol bits provided in the spectrum resource. In the frequency band configuration, the LTE and the NR can respectively exclusive one frequency band of the first frequency band and the second frequency band; or LTE may monopolize one frequency band, LTE and NR being shared in another frequency band; or the NR monopolizes one frequency band, and LTE and NR are shared in the other frequency band; or LTE and NR share the first frequency band and the second frequency band entirely.

In an exemplary embodiment, PDCCH symbols are configured on symbol bits 0, 1 as in the above example. In this example, the non-PDCCH symbol bits are 2-13 symbol bits. Based on this, in the exemplary embodiment, PDSCH of LTE and NR is configured on 2 to 13 symbol bits of the first frequency band, and spectrum is shared on the spectrum resource. And the PDSCH of NR is also configured on 2-13 symbol bits of the second frequency band, and the PDSCH of NR in the second frequency band monopolizes the frequency spectrum resource of the frequency band. In the exemplary embodiment, PDSCH of LTE may be configured on 2-13 symbol bits of the first frequency band, and exclusive of spectrum resources of the frequency band. And the PDSCH of NR is configured on 2-13 symbol bits of the second frequency band, and the spectrum resource of the frequency band is exclusive.

In step S230, a CRS of LTE is configured on at least one CRS symbol bit of the first frequency band; the CRS symbol bits share symbol bits with the PDCCH symbol bits and non-PDCCH symbol bits.

In an embodiment of the disclosure, a cell reference signal (Cell Reference Signals, CRS) of LTE is configured on at least one CRS symbol bit of a first frequency band. The CRS symbols may share symbols with the aforementioned PDCCH symbols and/or non-PDCCH symbols.

In an exemplary embodiment, PDCCH symbols are configured on symbol bits 0, 1 as in the above example, and non-PDCCH symbol bits are configured on symbol bits 2-13. The CRS of LTE is arranged on symbol bits 0, 4, 7, 11 of the first frequency band. Wherein, on symbol bit 0, CRS of LTE shares symbol bits with PDCCH symbol bits; on symbol bits 4, 7, 11, the CRS of LTE shares symbol bits with non-PDCCH symbol bits.

In an exemplary embodiment, the CRS of LTE configures the CRS of related LTE in MOD3 on the CRS symbol bits.

In step S240, the SSB of the NR is configured on the preset SSB block of the second frequency band.

In the embodiment of the disclosure, a Single Side Band (SSB) of NR is configured on a preset SSB block of the second frequency Band. The preset SSB block may be a part of RBs in the second frequency band, or may be a part of symbol bits in the part of RBs. On this SSB block, the SSB of NR shares symbol bits with the PDCCH symbol bits and non-PDCCH symbol bits.

In an exemplary embodiment, SSBs of NRs are arranged on symbol bits 8 to 11 in 20 RBs of the highest frequency band in the second frequency band. The sign bits 8-11 in the 20 RBs are the SSB blocks. On the SSB block, the SSB of NR shares symbol bits with the non-PDCCH symbol bits.

In step S250, according to the accessed NB-IoT service, the RE resources of the NB-IoT are configured on the sign bit of the second frequency band.

In the embodiment of the disclosure, resources of a Resource Element (RE) of the NB-IoT are dynamically configured on a symbol bit of the second frequency band according to whether the NB-IoT service is accessed by the base station and a specific situation of the accessed NB-IoT service. On the second band, the NB-IoT shares the relevant band spectrum resources with NR traffic.

In an exemplary embodiment, the dynamic spectrum sharing method is performed in a loop based on a preset time interval. And dynamically adjusting the frequency spectrum resource sharing allocation scheme according to the change of each service condition so as to adapt to the requirement of the service change.

It should be noted that the above numbering of the steps is only used to distinguish between different steps for convenience of operation and is not used to limit the order of execution between the steps. In actual implementation, the allocation of the spectrum resources is not limited to the above described order.

According to the dynamic spectrum sharing method, spectrum resource allocation and sharing modes of PDCCH and PDSCH of LTE and NR are dynamically adjusted according to NB-iot\LTE\NR three-mode sharing configuration requirements and respective service conditions, and the CRS of LTE is configured on CRS symbol bits of the first frequency band; configuring SSB of NR on a preset SSB block of a second frequency band; and configuring RE resources of the NB-IoT on the symbol bit of the second frequency band according to the accessed NB-IoT service. The method greatly improves the flexibility and reliability of the triple-mode system subsoiling frequency spectrum resource and reduces the networking and operation cost of the related system.

Fig. 3 shows a flow chart of another dynamic spectrum sharing method of an embodiment of the present disclosure. As shown in fig. 3, the dynamic spectrum sharing method may further include the following steps.

In step S310, when the base station supports full dynamic spectrum sharing, the PDCCH of the NR is further configured on at least one second PDCCH symbol bit of the first frequency band and the second frequency band.

In the embodiment of the disclosure, the base station is judged to support full dynamic spectrum sharing or partial dynamic spectrum sharing. According to different spectrum sharing modes supported by the base station, corresponding spectrum resource allocation schemes are different.

In the embodiment of the disclosure, when the base station supports full dynamic spectrum sharing, in addition to the PDCCHs for LTE and NR being configured on the PDCCH symbol positions of the first frequency band and the second frequency band respectively in step S210, the PDCCH for NR is additionally configured on at least one second PDCCH symbol position of the first frequency band and the second frequency band. The second PDCCH symbol bit is other symbol bits that are different from the PDCCH symbol bits described above. In the second PDCCH symbol bit, the PDCCH of NR is not only arranged in the second frequency band but also in the first frequency band. It should be noted that the non-PDCCH symbol bit should be other symbol bits that are not configured to either PDCCH symbol bit or to the second PDCCH symbol bit.

In an exemplary embodiment, on the basis of the exemplary embodiment of step S210 described above, PDCCH symbol bits are configured on symbol bits 0, 1, and the second PDCCH symbol bit is configured on symbol bit 2. Based on this, the PDCCH of NR is arranged not only in symbol bits 0 and 1 of the second frequency band but also in symbol bit 2 of the first and second frequency bands.

In step S320, when the base station supports full dynamic spectrum sharing, PDSCH of the NR is configured on the non-PDCCH symbol bit of the second frequency band; spectrum sharing of PDSCH of the LTE and NR on the non-PDCCH symbol bit of the first frequency band; and performing rate matching on the PDSCH of the NR and the CRS of the LTE on the CRS symbol bit of the first frequency band.

In the embodiment of the present disclosure, when the base station supports full dynamic spectrum sharing, a PDSCH of the NR is configured on the non-PDCCH symbol bit of the second frequency band; the PDSCH of the LTE and NR is spectrum shared on the non-PDCCH symbol bits of the first frequency band. Since the PDSCH of NR is also configured on the first frequency band, rate Matching (RM) is required for the PDSCH of NR on CRS symbol bits shared with CRS of LTE, i.e. NR PDSCH RM. Rate matching refers to the bits on a transport channel being retransmitted or punctured to match the carrying capacity of the physical channel, the channel mapping reaching the bit rate required for the transport format.

In step S330, when the base station supports partial dynamic spectrum sharing, PDSCH of the LTE is configured on the non-PDCCH symbol bit of the first frequency band; the PDSCH of the NR is configured on the non-PDCCH symbol bit of the second frequency band.

In the embodiment of the present disclosure, when the base station supports partial dynamic spectrum sharing, the PDCCH that is NR in step S310 is not configured on the second PDCCH symbol bit, but is configured only in step S210. And the PDSCH of LTE and NR are respectively configured on the non-PDCCH symbol positions of the first frequency band and the second frequency band, and the two do not share spectrum resources.

The dynamic spectrum sharing method provides two different spectrum resource allocation schemes according to whether the base station supports full dynamic spectrum sharing. When the base station supports full dynamic spectrum sharing, the spectrum resource occupation of PDCCH of the NR is sufficient, which is beneficial to the networking flexibility, resource utilization rate and downlink peak rate of the related system.

In the embodiment of the present disclosure, in the step S250, when the base station accesses NB-IoT service, the RE resources of the NB-IoT are configured on symbol bits of at least one resource block RB preset in the second frequency band. And, the base station may determine, based on the number of access to the NB-IoT traffic, to configure the number of RBs for RE resources of the NB-IoT.

In an exemplary embodiment, 1-3 resource blocks RBs are dynamically configured for NB-IoT traffic according to the NB-IoT traffic size. Specifically, 1-3 RBs of the low frequency band in the second frequency band can be allocated to NB-IoT service occupancy. When the NB-IoT traffic is less than the first threshold, then 1 RB is configured for NB-IoT traffic. When the NB-IoT traffic is greater than the first threshold and less than the second threshold, then 2 RBs are configured for NB-IoT traffic. When the NB-IoT traffic is greater than the second threshold, 3 RBs are configured for NB-IoT traffic. Wherein, RBs configuring NB-IoT service can be mutually continuous or mutually spaced, and 1 RB is spaced between two adjacent RBs configuring NB-IoT service.

In the embodiment of the disclosure, besides dynamically configuring the RB occupied by the NB-IoT in the spectrum, the NB-IoT RE resource configuration may be subjected to various resource configuration strategies based on the sign bit, and several possible sign bit configuration schemes are specifically given below.

In an example embodiment, RE resources of NB-IoT are configured on the PDCCH and non-PDCCH symbol bits of at least one RB preset in the second frequency band. That is, RE resources of the NB-IoT are configured on the full symbol bits of the corresponding RBs. As previously described, the PDCCH of NR has been configured on the corresponding PDCCH symbol bit, and the RE resources of NB-IoT are spectrally shared with the PDCCH of NR on the relevant spectrum resources. Therefore, on the PDCCH symbol bit of the corresponding RB, rate matching is required for the PDCCH of NR, i.e., NR PDCCH RM. Likewise, PDSCH with NR already configured on the corresponding non-PDCCH symbol bit, the RE resources of NB-IoT are spectrally shared with PDSCH of NR on the relevant spectrum resources. Therefore, on the non-PDCCH symbol bit of the corresponding RB, rate matching, i.e., NR PDSCH RM, is required for the PDSCH of the NR.

In an example embodiment, RE resources of NB-IoT are configured on the non-PDCCH symbol bit of at least one RB preset in the second frequency band. That is, the RE resources of the NB-IoT are configured only on non-PDCCH symbol bits of the corresponding RBs, and are not configured on PDCCH symbol bits. As previously described, PDSCH with NR already configured on the corresponding non-PDCCH symbol bit, the RE resources of NB-IoT are spectrally shared with PDSCH of NR on the relevant spectrum resources. Therefore, on the non-PDCCH symbol bit of the corresponding RB, rate matching, i.e., NR PDSCH RM, is required for the PDSCH of the NR.

According to the dynamic spectrum sharing method, whether spectrum resources are allocated to the NB-IoT service is determined according to whether the NB-IoT service is accessed by the base station, and the utilization rate of related spectrum resources is ensured. Meanwhile, under the condition that NB-IoT service is accessed, the method also provides a plurality of NB-IoT resource allocation schemes, configuration and switching can be carried out according to service needs and deployment demands, flexibility and convenience of NB-IoT service are improved, and overall performance of a related system is greatly improved.

As can be seen from the above, according to the dynamic spectrum sharing method provided by the embodiment of the disclosure, according to the NB-iot\lte\nr three-mode sharing configuration requirement and the respective service conditions, the three-mode dynamic spectrum sharing (3M-DSS) sharing mode is dynamically adjusted and switched, and NR PDCCH RM and NR PDSCH RM are adaptively performed, so that the networking flexibility, the resource utilization rate and the downlink peak rate of the 3M-DSS system are improved. There may be multiple schemes for spectrum resource allocation and sharing according to NB-IoT/LTE/NR triple-mode respective traffic and base station configuration.

Fig. 4 illustrates an exemplary flow chart of a dynamic spectrum sharing method of an embodiment of the present disclosure. In the embodiment of the present disclosure, the foregoing dynamic spectrum sharing methods shown in fig. 2 and fig. 3 are combined, which provides a scheme for allocating and sharing multiple spectrum resources according to respective services of NB-iot\lte\nr three modes and a base station configuration situation. As shown in fig. 4, the dynamic spectrum sharing method may include the following steps.

In step S410, the PDCCH of LTE is configured on at least one PDCCH symbol bit of the first frequency band; and configuring PDCCH of NR on the PDCCH symbol position of the second frequency band.

In an embodiment of the disclosure, a PDCCH of LTE is configured on at least one PDCCH symbol bit of a first frequency band. And the PDCCH of NR is configured on said PDCCH symbol bit of the second frequency band. The PDCCHs of LTE and NR are configured on corresponding PDCCH symbol bits of different frequency bands.

In step S420, PDSCH of LTE and NR is configured on non-PDCCH symbol bits of the first and second frequency bands.

In the embodiment of the disclosure, PDSCH of LTE and NR is configured on non-PDCCH symbol bits of the first frequency band and the second frequency band. In the frequency band configuration, the LTE and the NR can respectively exclusive one frequency band of the first frequency band and the second frequency band; or LTE may monopolize one frequency band, LTE and NR being shared in another frequency band; or the NR monopolizes one frequency band, and LTE and NR are shared in the other frequency band; or LTE and NR share the first frequency band and the second frequency band entirely.

In step S430, the CRS of LTE is configured on at least one CRS symbol bit of the first frequency band; the CRS symbol bits share symbol bits with the PDCCH symbol bits and non-PDCCH symbol bits.

In the embodiment of the disclosure, CRS of LTE is configured on at least one CRS symbol bit of the first frequency band. The CRS symbols may share symbols with the aforementioned PDCCH symbols and/or non-PDCCH symbols.

In step S440, the SSB of the NR is configured on the preset SSB block of the second frequency band.

In the embodiment of the disclosure, the SSB of the NR is configured on a preset SSB block of the second frequency band. The preset SSB block may be a part of RBs in the second frequency band, or may be a part of symbol bits in the part of RBs. On this SSB block, the SSB of NR shares symbol bits with the PDCCH symbol bits and non-PDCCH symbol bits.

In step S450, it is determined that the base station supports full dynamic spectrum sharing or partial dynamic spectrum sharing.

In step S460, when the base station supports full dynamic spectrum sharing, the PDCCH of the NR is further configured on at least one second PDCCH symbol bit of the first frequency band and the second frequency band.

In step S465, when the base station supports full dynamic spectrum sharing, PDSCH of the NR is configured on the non-PDCCH symbol bit of the second frequency band; spectrum sharing of PDSCH of the LTE and NR on the non-PDCCH symbol bit of the first frequency band; and performing rate matching on the PDSCH of the NR and the CRS of the LTE on the CRS symbol bit of the first frequency band.

In the embodiment of the present disclosure, when the base station supports full dynamic spectrum sharing, a PDSCH of the NR is configured on the non-PDCCH symbol bit of the second frequency band; the PDSCH of the LTE and NR is spectrum shared on the non-PDCCH symbol bits of the first frequency band. Since the PDSCH of NR is also configured on the first frequency band, rate matching, i.e. NR PDSCH RM, is required for the PDSCH of NR on CRS symbols shared with CRS of LTE. Rate matching refers to the bits on a transport channel being retransmitted or punctured to match the carrying capacity of the physical channel, the channel mapping reaching the bit rate required for the transport format.

In step S470, it is determined whether the NB-IoT traffic is accessed by the base station.

In an embodiment of the disclosure, it is determined whether a base station has access to NB-IoT traffic. The corresponding spectrum resource allocation schemes are also different depending on whether the base station has access to NB-IoT traffic.

In step S471, when the base station does not access NB-IoT traffic, it is unshared by NR spectrum in the second frequency band.

In the disclosed embodiments, NR does not need to share spectrum with NB-IoT in the second frequency band because the base station does not access NB-IoT traffic. The spectrum resources of the second frequency band are allocated to PDCCH, PDSCH and SSB of NR according to the foregoing steps.

In step S472, when the base station has access to NB-IoT service, the NB-IoT and NR dynamic spectrum sharing is performed in the second frequency band, and RE resources of the NB-IoT are configured on symbol bits of at least one resource block RB preset in the second frequency band.

Configuration scheme one: in an example embodiment, RE resources of NB-IoT are configured on the PDCCH and non-PDCCH symbol bits of at least one RB preset in the second frequency band. That is, RE resources of the NB-IoT are configured on the full symbol bits of the corresponding RBs. As previously described, the PDCCH of NR has been configured on the corresponding PDCCH symbol bit, and the RE resources of NB-IoT are spectrally shared with the PDCCH of NR on the relevant spectrum resources. Therefore, on the PDCCH symbol bit of the corresponding RB, rate matching is required for the PDCCH of NR, i.e., NR PDCCH RM. Likewise, PDSCH with NR already configured on the corresponding non-PDCCH symbol bit, the RE resources of NB-IoT are spectrally shared with PDSCH of NR on the relevant spectrum resources. Therefore, on the non-PDCCH symbol bit of the corresponding RB, rate matching, i.e., NR PDSCH RM, is required for the PDSCH of the NR.

Configuration scheme II: in an example embodiment, RE resources of NB-IoT are configured on the non-PDCCH symbol bit of at least one RB preset in the second frequency band. That is, the RE resources of the NB-IoT are configured only on non-PDCCH symbol bits of the corresponding RBs, and are not configured on PDCCH symbol bits. As previously described, PDSCH with NR already configured on the corresponding non-PDCCH symbol bit, the RE resources of NB-IoT are spectrally shared with PDSCH of NR on the relevant spectrum resources. Therefore, on the non-PDCCH symbol bit of the corresponding RB, rate matching, i.e., NR PDSCH RM, is required for the PDSCH of the NR.

In step S480, when the base station supports partial dynamic spectrum sharing, PDSCH of the LTE is configured on the non-PDCCH symbol bit of the first frequency band; the PDSCH of the NR is configured on the non-PDCCH symbol bit of the second frequency band.

In step S490, it is determined whether the NB-IoT traffic is accessed by the base station.

In the embodiment of the disclosure, under the condition of supporting partial dynamic spectrum sharing, whether the NB-IoT service is accessed to the base station is judged. This step is similar to the previous step S470 and is not repeated here.

In step S491, when the base station is not accessing NB-IoT traffic, it is unshared by NR spectrum in the second frequency band.

In the embodiment of the present disclosure, this step is similar to the aforementioned step S471 and is not repeated here.

In step S492, when the base station has access to NB-IoT service, the NB-IoT and NR dynamic spectrum sharing is performed in the second frequency band, and the RE resources of the NB-IoT are configured on the symbol bits of at least one resource block RB preset in the second frequency band.

In the disclosed embodiment, this step is similar to the aforementioned step S492 and is not repeated here.
