Technical Field

Background

In the 800M frequency division duplex (Frequency Division Duplexing, FDD) frequency band heavy-tillage scenario, considering that 800M is a large base network with wide coverage of long term evolution (Long Term Evolution, LTE) and is also a main carrier network of VoLTE (Voice Over LTE), a certain bandwidth needs to be reserved for LTE and VoLTE for use in 800M, so that the dynamic spectrum sharing (Dynamic Spectrum Sharing, DSS) technology between 4G and 5G is the preferred technology for 800M FDD frequency band heavy-tillage.

In the related art, there are mainly two schemes for implementing an 800M small bandwidth (e.g., 10M) uplink DSS: scheme one, 10M New air interface (NR) +5MLTE, namely NR maximum shared bandwidth can reach 10M, LTE maximum shared bandwidth can reach 5M, NR and LTE are unequal bandwidth sharing; scheme two, 10M NR+10M LTE, namely NR maximum shared bandwidth can reach 10M, LTE maximum shared bandwidth can reach 10M, NR and LTE are equal bandwidth sharing.

However, the two schemes cannot be dynamically changed along with the service condition of the terminal, and there is also a problem of bandwidth compatibility between the LTE terminal and the NR terminal, and the physical uplink control channel (Physical Uplink Control Channel, PUCCH) in the middle of the bandwidth causes fragmentation of the NR physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), which affects the uplink rate of the terminal.

Fig. 1 illustrates a system for supporting dynamic spectrum sharing of an LTE network and an NR network, which system 100 may include an LTE network and an NR network overlaid on the LTE network.

Wherein the coverage area of the NR network is 101. The NR network includes base stations 102 (e.g., gnbs), which base stations 102 provide wireless services for NR terminals 103 within coverage area 101.

Fig. 2 is a flow chart illustrating a method of resource allocation according to an example embodiment. Referring to fig. 2, the resource allocation method provided by the embodiment of the present disclosure may include the following steps.

Step S201, configuring an uplink shared bandwidth resource, where the uplink shared bandwidth resource includes: a shared resource segment of the LTE network and the NR network, and a flexible resource segment of the LTE network and the NR network.

The uplink shared bandwidth resource is a section of spectrum shared by the LTE network and the NR network, the shared resource section of the LTE network and the NR network can be configured to be the shared spectrum of the LTE network and the NR network, and the flexible resource section of the LTE network and the NR network can be configured to be the shared spectrum of the LTE network and the NR network or the exclusive shared spectrum of the NR network according to service conditions.

In an exemplary embodiment, the shared resource segments of the LTE network and the NR network and the flexible resource segments of the LTE network and the NR network respectively occupy half of the uplink shared bandwidth resources.

That is, in the embodiment of the present disclosure, the uplink shared bandwidth resource includes a shared resource segment of the LTE network and the NR network, and a flexible resource segment of the LTE network and the NR network, and the shared resource segment and the flexible resource segment each occupy half of the uplink shared bandwidth resource.

For example, the uplink shared bandwidth resource is 800M small bandwidth 10M, the shared resource segment of the lte network and the NR network is the upper 5M of 10M, and the flexible resource segment of the lte network and the NR network is the lower 5M of 10M. Alternatively, the flexible resource segment of the LTE network and the NR network is the upper 5M of 10M, and the shared resource segment of the LTE network and the NR network is the lower 5M of 10M.

In an exemplary embodiment, a first LTE PUCCH is provided at a first boundary of an uplink shared bandwidth resource, and a second LTE PUCCH is provided at a second boundary of the uplink shared bandwidth resource; a first NR PUCCH is arranged outside a first boundary of the uplink shared bandwidth resource, and a second NR PUCCH is arranged outside a second boundary of the uplink shared bandwidth resource; the first LTE PUCCH is adjacent to the first NR PUCCH, and the second LTE PUCCH is adjacent to the second NR PUCCH.

In an exemplary embodiment, the first boundary is an upper boundary of the uplink shared bandwidth resource, and the second boundary is a lower boundary of the uplink shared bandwidth resource; or the first boundary is the lower boundary of the uplink shared bandwidth resource, and the second boundary is the upper boundary of the uplink shared bandwidth resource.

Considering that NR is smaller than LTE boundary guard bands at the same bandwidth, the number of NR Resource Blocks (RBs) is 6% greater than the number of LTE RBs. For example, in the case of a bandwidth of 10M, LTE may occupy 50 RBs, NR may occupy 53 RBs, and NR may be 3 more RBs than LTE. Accordingly, the LTE PUCCH may be set at the boundary of the uplink shared bandwidth resource, the NR PUCCH is set outside the boundary of the uplink shared bandwidth resource, and the NR PUCCH is adjacent to the LTE PUCCH. Wherein, the LTE PUCCH occupies about 1-2 RBs, and the NR PUCCH occupies about 1-2 RBs.

Specifically, a first LTE PUCCH may be set at a first boundary of an uplink shared bandwidth resource, a second LTE PUCCH may be set at a second boundary of the uplink shared bandwidth resource, a first NR PUCCH may be set outside the first boundary of the uplink shared bandwidth resource, and a second NR PUCCH may be set outside the second boundary of the uplink shared bandwidth resource. The first LTE PUCCH is adjacent to the first NR PUCCH, and the second LTE PUCCH is adjacent to the second NR PUCCH.

Therefore, the flexible resource segments of the LTE network and the NR network may or may not support the LTE network. Therefore, the LTE PRACH is configured in the shared resource segment of the LTE network and the NR network in the embodiments of the present disclosure. Wherein the LTE PRACH occupies about 6 RBs.

The shared resource segment of the LTE network and the NR network may include, in addition to the LTE PRACH, a first PUSCH, i.e., a shared uplink traffic channel of the LTE network and the NR network. And, the LTE PRACH is adjacent to the first LTE PUCCH, and the first PUSCH is adjacent to the LTE PRACH.

In an exemplary embodiment, flexible resource segments of an LTE network and an NR network include: NR PRACH and second PUSCH; wherein the NR PRACH is adjacent to the second LTE PUCCH and the second PUSCH is adjacent to the NR PRACH.

As already described above, the shared resource segments of the LTE network and the NR network may be configured to share a spectrum with the LTE network and the NR network, and the flexible resource segments of the LTE network and the NR network may be configured to share a spectrum with the LTE network and the NR network or to share a spectrum with the NR network alone according to traffic conditions. Thus, flexible resource segments of LTE networks and NR networks may support NR networks. Therefore, the NR PRACH is configured in the flexible resource segments of the LTE network and the NR network in the embodiments of the present disclosure. Wherein, NR PRACH occupies about 6 RBs.

The flexible resource segments of the LTE network and the NR network may include, in addition to the NR PRACH, a second PUSCH adjacent to the second LTE PUCCH, the second PUSCH adjacent to the NR PRACH. The second PUSCH may be configured as a shared uplink traffic channel of the LTE network and the NR network, or an exclusive shared uplink traffic channel of the NR network, according to traffic conditions.

In an exemplary embodiment, the shared resource segments of the LTE network and the NR network may be disposed above the uplink shared bandwidth resources, and the flexible resource segments of the LTE network and the NR network may be disposed below the uplink shared bandwidth resources.

In this case, the first boundary is an upper boundary, the second boundary is a lower boundary, the first LTE PUCCH is disposed at the upper boundary of the uplink shared bandwidth resource, the second LTE PUCCH is disposed at the lower boundary of the uplink shared bandwidth resource, the first NR PUCCH is disposed outside the upper boundary of the uplink shared bandwidth resource, the second NR PUCCH is disposed outside the lower boundary of the uplink shared bandwidth resource, the LTE PRACH is adjacent to the first LTE PUCCH, the first PUSCH is adjacent to the LTE PRACH, the NR PRACH is adjacent to the second LTE PUCCH, and the second PUSCH is adjacent to the NR PRACH.

Step S202, obtaining LTE terminal traffic and NR terminal traffic.

In this step, LTE terminal traffic and NR terminal traffic in DSS cells are counted over a period of time. Wherein a DSS cell may be understood as an overlapping coverage cell of an LTE network and an NR network.
