Description

Unlicensed frequency band scheduling method and device, base station and network equipment

Technical Field

The present invention relates to the field of wireless technologies, and in particular, to a method and an apparatus for scheduling unlicensed frequency bands, a base station, and a network side device.

Background

The 3GPP proposes an evolution multimedia broadcast multicast service (enhanced Multimedia Broadcast/Multicast Service, eMBMS) based on an LTE network, and uses a broadcast mode to transmit and save air interface resources, and uses less resource consumption to serve as many users as possible. The LTE adopts a Multicast broadcast single frequency network (Multicast/Broadcast Single Frequency Network, MBSFN) technology to transmit the eMBMS, cells belonging to the same MBSFN area adopt the same frequency band to simultaneously transmit service data, and the cells are simultaneously received at a receiving end to carry out soft combining, which is equivalent to realizing downlink transmission macro diversity, reducing mutual interference among cells and enhancing user experience.

Furthermore, as an extension and supplement to 5G NR, research into the 5G NR unlicensed band (NR in Unlicensed Spectrum, NR-U) has been initiated. An initial purpose of NR-U is to consider limited licensed spectrum resources, and to meet the service requirements of seamless coverage and high data rate, access services are provided in an unlicensed band by using an NR protocol, for example, when a terminal has a large-traffic non-real-time service, the access services may be carried by an unlicensed band cell, so as to relieve the pressure of the licensed band cell. Because of the unlicensed nature of unlicensed spectrum, some countries or regions require channel occupancy monitoring before any communication is performed on unlicensed spectrum, i.e., LBT (Listen Before Talk) is successful before communication can be performed. Thus, LBT failure will affect any air interface interaction links (including control plane and user plane) in the cellular network protocol. When LBT on a certain time-frequency resource fails, a broadcast or multicast message cannot be sent on the time-frequency resource, resulting in delay or failure of terminal-side reception.

In the eMBMS network architecture of LTE, an access network side introduces a multi-cell/multicast coordination entity (Multicell/Multicast Coordination Entity, MCE) to interact with a base station eNB through an M2 interface. The MCE is mainly used for uniformly managing radio resources of all eNBs in the MBSFN area when MBSFN transmission is carried out, and comprises the steps of distributing time-frequency resources, configuring specific radio parameters and the like so as to ensure the synchronization of eMBMS transmission among a plurality of cells.

Therefore, the implementation of the multi-cell MBSFN transmission mode mainly depends on MCE for resource coordination and scheduling among cells. However, the current eMBMS does not consider an unlicensed band deployment scenario, especially when LBT failure may cause eMBMS data to be unable to be transmitted. On one hand, as MBSFN requires that all cells in the managed area use the same time-frequency resource for transmission, when using an unlicensed frequency band, all cells are required to successfully transmit LBT on the same time-frequency resource; on the other hand, when the MCE coordinates and schedules the time-frequency resources, the situation that the time-frequency resources of each cell are not occupied currently is taken as a reference, and unlicensed frequency band resources with idle all cells or high LBT success rate are difficult to select.

Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

Fig. 1 is a schematic diagram of a system architecture of an embodiment of a method for scheduling unlicensed band resources according to an embodiment of the present invention. The scheduling method is applied to a system for transmitting the eMBMS by adopting a multicast broadcast single frequency network MBSFN technology. Wherein cells belonging to the same MBSFN area adopt the same frequency band to simultaneously transmit service data, namely one MBSFN area comprises one or more cells transmitting the same service data.

Thus, transmission using MBSFN techniques not only requires that cells joining the same MBSFN area be synchronized in time, but also requires that each cell transmitting the same traffic data within the same MBSFN area use the same radio resources. Referring to fig. 1, in an eMBMS network system adopting the scheduling method according to the embodiment of the present invention, an access network side introduces a multi-cell/multicast coordination entity (multi-cell/Multicast Coordination Entity, MCE) for unified management of radio resources of all base stations eNB in an MBSFN area when performing MBSFN service transmission, including allocation of time-frequency resources and configuration of specific transmission parameters, so as to ensure synchronization of eMBMS transmission among multiple cells.

Alternatively, the MCE is a separate physical entity, or may be deployed within another physical entity (e.g., eNB). In either case, the MCE needs to establish an M2 interface with all enbs within the corresponding MBSFN area. In a centralized MCE architecture, one MCE is responsible for managing all enodebs within the corresponding MBSFN area, as shown in fig. 2, one MCE may control multiple enbs, each of which may process one or more cells correspondingly.

It should be noted that, as shown in fig. 2, the system architecture adopting the scheduling method according to the embodiment of the present invention may further include:

A broadcast multicast service center (Broadcast Multicast Service Center, BM-SC) located in the core network for responsible authentication, charging and traffic shaping for the content provider;

an MBMS gateway (MBMS-GW) belonging to a logic node for multicasting IP message from BM-SC to all eNodeB contained in MBSFN area; while session control signaling is handled via the mobility management entity (Mobility Management Entity, MME).

In order to solve the problem that in the prior art, when MBSFN transmission is performed, an unlicensed frequency band deployment scenario is not considered, and the LBT failure may cause incapability of transmitting eMBMS data, the embodiment of the invention provides a scheduling method of unlicensed frequency band resources, which collects unlicensed frequency band resource state information of cells through a base station and reports the information to a resource coordination entity, so that the resource coordination entity can schedule unlicensed frequency band time-frequency resources which are idle (i.e. have higher LBT success rate) for a plurality of cells according to the unlicensed frequency band resource state information reported by the base station, and synchronize LBT initiation time, thereby improving the probability of LBT success of all cells in the same MBSFN area and guaranteeing multicast/broadcast service transmission under the unlicensed frequency band.

The method for scheduling unlicensed band resources according to an embodiment of the present invention is applied to a base station, as shown in fig. 2, and includes:

s210, collecting unauthorized frequency band resource state information of a cell in the base station;

s220, reporting the acquired unlicensed frequency band resource state information to a resource coordination entity;

s230, receiving unlicensed band time-frequency resource scheduling information sent by the resource coordination entity according to the unlicensed band resource state information.

According to the scheduling method of the unlicensed band resources, a base station acquires unlicensed band resource state information of a cell and reports the information to a resource coordination entity, and the resource coordination entity schedules the same unlicensed band time-frequency resources and synchronous LBT initiation time for the cell to which at least one base station belongs according to the unlicensed band resource state information reported by the base station and sends time-frequency resource scheduling information to at least one base station. Specifically, to improve the probability of LBT success of all cells in the same MBSFN area, the resource coordination entity schedules unlicensed frequency band time-frequency resources with relatively idle or relatively high LBT success rate for a plurality of cells.

It should be noted that, in the embodiment of the present invention, as shown in fig. 1, the resource coordination entity may be an MCE in an eMBMS network system.

Further, in step S210, unlicensed band resource status information of the cell in the base station is collected by at least one of the following manners:

layer 2 measurement, terminal minimization of drive tests (Minimization Drive Test, MDT) reporting and terminal measurement report reporting.

In step S210 and step S220, the unlicensed band resource status information includes at least one of:

the LBT success rate of at least one cell on a preset time-frequency resource;

the LBT failure rate of at least one cell on a preset time-frequency resource;

It should be noted that, the unlicensed band resource status information collected by the base station is used to describe an idle status of an unlicensed band time-frequency resource on a preset time-frequency resource, a success rate of LBT initiation, etc. of a cell to which the base station belongs, and the specific content is not limited by the above listed information.

In the embodiment of the present invention, optionally, in step S220, the unlicensed band resource status information may be reported to the resource coordination entity through an interface between the base station and the resource coordination entity. For example, as shown in fig. 1, the interface is an M2 interface in eMBMS.

Further, in step S230, the received unlicensed band time-frequency resource scheduling information includes:

the resource coordination entity is an unlicensed frequency band time-frequency resource scheduled by a cell in the base station; and

Specifically, the resource coordination entity schedules the same unlicensed band time-frequency resource and synchronous LBT initiation time for a cell to which at least one base station belongs according to the received unlicensed band resource state information, and sends unlicensed band time-frequency resource scheduling information to at least one base station, where the unlicensed band time-frequency resource scheduling information includes the unlicensed band time-frequency resource scheduled by the resource coordination entity for the cell in the base station and the initiation time of synchronous LBT on the unlicensed band time-frequency resource.

In the embodiment of the invention, in order to improve the probability of LBT success of all cells in the same MBSFN area, a resource coordination entity selects the same unlicensed frequency band time-frequency resource for the cell to which at least one base station belongs according to a preset coordination rule, so that unlicensed frequency band time-frequency resources with relatively idle or relatively high LBT success rate can be scheduled for a plurality of cells, and the probability of LBT success of all cells in the same MBSFN area is improved.

Specifically, the resource coordination entity selects a preset coordination rule of the same unlicensed frequency band time-frequency resource for a cell to which at least one base station belongs, which will be described in detail below.

In the embodiment of the present invention, after step S230, the method further includes:

Specifically, a cell to which the base station receiving the unlicensed band time-frequency resource scheduling information belongs adopts unlicensed band time-frequency resources indicated by the unlicensed band time-frequency resource scheduling information, and initiates LBT at the initiation time of the indicated synchronous LBT.

Further, the cell with successful LBT adopts the unlicensed frequency band time-frequency resource indicated by the unlicensed frequency band time-frequency resource scheduling information to send service data; and the base station of the cell with the LBT failure reports the LBT failure information to a resource coordination entity connected with the base station.

Thus, the method further comprises:

In the embodiment of the present invention, optionally, in step S230, the unlicensed band time-frequency resource scheduling information sent by the resource coordination entity may be received through an interface between the base station and the resource coordination entity;

in addition, if the LBT of the cell fails, when the LBT failure information is reported to the resource coordination entity, the LBT failure information can be reported through an interface between the base station and the resource coordination entity.

For example, as shown in fig. 1, the interface may be an M2 interface in eMBMS.

By adopting the scheduling method of the unlicensed band resources, the base station collects the unlicensed band resource state information of the cells in the base station, so that a resource coordination entity connected with the base station can schedule unlicensed band time-frequency resources which are idle (i.e. LBT success rate is high) for a plurality of cells according to the unlicensed band resource state information reported by the base station, and synchronize LBT initiation time, thereby improving the probability of LBT success of all cells in the same MBSFN area, ensuring multicast/broadcast service transmission in the unlicensed band, and solving the problem that eMBMS data cannot be transmitted due to LBT failure without considering unlicensed band deployment scenes when MBSFN transmission is performed.

Another embodiment of the present invention further provides a scheduling method of unlicensed band resources, which is applied to a resource coordination entity, as shown in fig. 3, where the method includes:

s310, receiving state information of unlicensed frequency band resources reported by at least one base station;

According to the scheduling method of the unlicensed band resources, a resource coordination entity schedules the same unlicensed band time-frequency resources and synchronous LBT initiation time for a cell to which at least one target base station in the base station belongs according to the unlicensed band resource state reported by at least one base station, and sends time-frequency resource scheduling information to the target base station. Specifically, to improve the probability of LBT success of all cells in the same MBSFN area, the resource coordination entity schedules unlicensed frequency band time-frequency resources with relatively idle or relatively high LBT success rate for a plurality of cells.

In the embodiment of the present invention, in step S310, the received unlicensed band resource status information includes at least one of the following:

The LBT success rate of at least one cell on a preset time-frequency resource;

the LBT failure rate of at least one cell on a preset time-frequency resource;

In S320, the unlicensed band time-frequency resource scheduling information sent by the resource coordination entity to the target base station includes:

The following illustrates a specific implementation manner of the unlicensed band resource scheduling method according to the embodiment of the present invention.

Example 1

In a first embodiment, the method for scheduling unlicensed band resources according to the embodiment of the present invention includes the following steps:

at least one base station acquires unlicensed frequency band resource state information through downlink layer 2 measurement;

at least one base station reports the acquired unauthorized frequency band resource state information to a connected resource coordination entity;

the resource coordination entity selects an unlicensed frequency band time-frequency resource with the lowest average LBT failure rate as a shared resource of all cells in the MBSFN area according to the received unlicensed frequency band resource state information of at least one base station, and sends the determined unlicensed frequency band time-frequency resource and corresponding LBT synchronous initiation time (namely, unlicensed frequency band time-frequency resource scheduling information) to the base station to which all cells in the MBSFN area belong;

for example, the average value of LBT failure rates of three cells is shown in table 1 below: and selecting the time-frequency resource 1 with the lowest average LBT failure rate in the three cells as an unlicensed frequency band time-frequency resource commonly used by all cells in the MBSFN area.

TABLE 1

	Time-frequency resource 1	Time-frequency resource 2	Time-frequency resource 3	Time-frequency resource 4
					Cell 1LBT failure rate	30％	20％	15％	30％
Cell 2LBT failure rate	5％	50％	15％	15％
					Cell 3LBT failure rate	5％	10％	15％	30％
Average LBT failure rate	13.3％	26.7％	15％	25％

Initiating LBT (local binary transmission) at LBT synchronous initiation time indicated by the scheduling information on an unlicensed frequency band time-frequency resource indicated by the scheduling information by all cells in the MBSFN area;

the cell with successful LBT uses the unlicensed frequency band time-frequency resource indicated by the scheduling information to send service data, and the base station of the cell with failed LBT reports the LBT failure information to the resource coordination entity connected with the base station;

the resource coordination entity changes the MBSFN area to which the cell to which the LBT failure information belongs and schedules new time-frequency resources.

In the first embodiment, the resource coordination entity uses the average value of the unlicensed band resource status information of the base station as the determination principle, and selects the unlicensed band time-frequency resource with the average value capable of representing the unlicensed band time-frequency resource with the higher idle or LBT success rate as the unlicensed band time-frequency resource commonly used by the cells.

Example two

for example, the LBT failure rates for three cells are shown in table 2 below: and selecting the time-frequency resource 3 corresponding to the lowest value in the highest LBT failure rate from different unlicensed time-frequency resources of the three cells as the unlicensed frequency band time-frequency resource commonly used by all cells in the MBSFN area.

TABLE 2

	Time-frequency resource 1	Time-frequency resource 2	Time-frequency resource 3	Time-frequency resource 4
					Cell 1LBT failure rate	30％	20％	15％	30％
Cell 2LBT failure rate	5％	50％	15％	15％
					Cell 3LBT failure rate	5％	10％	15％	30％
Highest LBT failure rate	30％	50％	15％	30％

In the second embodiment, the resource coordination entity uses the most value of the unlicensed band resource status information of the base station as the determination principle, and selects the unlicensed band time-frequency resource corresponding to the least value in the highest LBT failure rate as the unlicensed band time-frequency resource commonly used in the cell in the base station by analyzing the highest LBT failure rates of the unlicensed band time-frequency resources of the plurality of base stations in the same single-frequency network area.

Example III

and the resource coordination entity selects M base stations with LBT failure rate lower than a first threshold under the same unlicensed frequency band time-frequency resource according to the received unlicensed frequency band resource state information, and allocates the unlicensed frequency band time-frequency resource to the same MBSFN area.

For example, LBT failure rates of different time-frequency resources are shown in table 3 below, with respect to time-frequency resource 1, cell 2 and cell 3 having LBT failure rates lower than 10% are classified into MBSFN area 1, with respect to time-frequency resource 2, cell 1 and cell 3 having LBT failure rates lower than 25% are classified into MBSFN area 2, and so on.

TABLE 3 Table 3

	Time-frequency resource 1	Time-frequency resource 2	Time-frequency resource 3	Time-frequency resource 4
					Cell 1LBT failure rate	30％	20％	15％	30％
Cell 2LBT failure rate	5％	50％	15％	15％
					Cell 3LBT failure rate	5％	10％	15％	30％
LBT failure rate threshold	10％	25％	20％	20％
