Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
Referring to fig. 1 and fig. 2, a system for planning BWP resources by a base station according to an embodiment of the present invention includes a base station 10 and a user equipment 30.
In one particular embodiment, the entire 5G mobile system bandwidth is limited, for example: the typical maximum bandwidth of the current 5G mobile system is 100M bandwidth, and the 100M bandwidth can be divided into a certain number of BWP resources and allocated to a first batch of cells within a certain range; when the coverage of the 5G mobile system exceeds the first batch of cells, the BWP resources of the number need to be reused and allocated to the second batch of cells within the coverage of the 5G mobile system; the distance between the first cells and the second cells is the reuse distance. Namely, the first batch of cells and the second batch of cells are within the multiplexing distance range.
In mobile service, the base station 10 serves the user equipment 30 of each cell within its reuse distance. For example, in the 5G mobile service, the base station 10 configures BWP to the user equipment 30 of each cell within the multiplexing distance range; and configures the user equipment 30 with different active BWPs according to different needs or traffic demands of the user equipment 30. Specifically, the base station 10 may allocate or configure an initial BWP, a dedicated BWP, an active BWP to the user equipment 30 of each cell within the reuse distance range; it is also possible to allocate a reserved BWP for the cell where the user equipment 30 is located as a backup. It can be understood that, the PRB used by each cell (12 consecutive carriers in the frequency domain) has different positions, so that the reserved BWP resources allocated to different cells within the multiplexing distance range have different PRB positions, thereby realizing different reserved BWPs allocated to different cells within the multiplexing distance range.
Referring to fig. 2, the base station 10 includes a configuration module 11, a detection module 13, a switching module 15, and a capacity expansion module 18.
In this embodiment, the configuration module 11 is configured to allocate different reserved BWPs to different cells within the multiplexing distance range; and allocating the initial BWP and the dedicated BWP to the user device 30; and is further configured to issue the reserved BWP of the cell corresponding to the user equipment 30.
The detection module 13 is configured to detect whether the user equipment 30 triggers a high priority service. Specifically, the detecting module 13 is further configured to detect whether the high-priority service triggered by the user equipment 30 is a small-bandwidth high-priority service or a large-bandwidth high-priority service.
The handover module 15 is configured to handover an active BWP currently used by the user equipment 30 to a reserved BWP of a cell corresponding to the user equipment 30. Further, the switching module 15 is also configured to switch back the currently active BWP of the user equipment 30 occupying the BWP resource of the reserved BWP to be expanded to the initial BWP or the dedicated BWP.
The capacity expansion module 18 is configured to, before the configuration module 11 issues the reserved BWP of the cell corresponding to the user equipment 30, perform capacity expansion on the reserved BWP according to the required amount of the high-bandwidth high-priority service of the user equipment 30.
Referring to fig. 3, the user equipment 30 includes a receiving module 31, where the receiving module 31 is configured to receive an initial BWP and a dedicated BWP allocated by the base station 10; also for receiving the active BWP assigned by the base station 10; and the receiving base station 10 switches the active BWP currently used by the user equipment 30 to this reserved BWP when high priority traffic is triggered. In this way, the base station 10 performs reasonable planning on BWP resources, so that the user equipment 30 ensures the quality of the service when triggering the high-priority service.
With reference to fig. 4 and fig. 5, a detailed description is given below of a method for planning BWP resources by a base station of the system for planning BWP resources by a base station according to the present application, where the method includes the following steps executed in sequence:
s1, the base station 10 allocates different reserved BWPs to different cells within the multiplexing distance range; it is understood that the reserved BWP is reserved for the traffic needs of the user equipment 30 of the cell within the multiplexing distance range; in step S1, the reserved BWP is not allocated and used by the user equipment 30.
Specifically, the following illustrates a specific operation of allocating reserved BWPs: for example: the reserved BWP is divided by taking 5M bandwidth, 15Khz subcarriers and specific scheduling resources as standards, and the PRB positions used by each cell are different, so that the PRB positions of the reserved BWP resources of 20 different cells are different, but other resource information is consistent. The reserved BWP resources of 20 cells are allocated in a typical three-sector. When the number of different cells exceeds 20, the multiplexing allocation is continued.
S3, the base station 10 allocates an initial BWP and a dedicated BWP to the user equipment 30, and activates one of the initial BWP and the dedicated BWP as the currently activated BWP of the user equipment 30 according to the current needs of the user equipment 30;
specifically, in step S3, the base station 10 issues the initial BWP and the dedicated BWP to the user equipment 30 through any one of the MIB message, SIB message, RRC reconfiguration message, and DCI message. (refer to FIG. 1)
In this embodiment, in the 5GNR FDD system, the base station 10 may configure four uplink BWPs and four downlink BWPs at most for one user equipment 30. And one user equipment 30 configures 4 BWP pairs at maximum. The BWP Pair means that the ID of the upstream BWP is the same as the ID of the downstream BWP, and the center frequency points of the upstream BWP and the downstream BWP are the same, but the bandwidth and the subcarrier spacing may not be the same. The four uplink BWPs comprise an initial uplink BWP and a special uplink BWP; the four downlink BWPs include an initial downlink BWP and a dedicated downlink BWP. But the user equipment can activate only one of the BWPs at each time.
Further, the base station 10 activates one of the initial BWPs or the dedicated BWPs as the current activated BWP of the user equipment according to the current needs of the user equipment 30, specifically: at a certain time when the ue 30 is in the initial access phase, the bs 10 activates one of the initial BWPs as the current activated BWP of the ue 30; at a certain moment when the user equipment 30 performs data traffic transmission, the base station 10 activates one of the dedicated BWPs as the currently activated BWP of the user equipment 30.
S5, the base station detects whether the ue 30 triggers a high priority service;
s9, when the base station 10 detects that the user equipment 30 triggers the high-priority service, the base station 10 issues the reserved BWP of the cell corresponding to the user equipment 30, and switches the active BWP currently used by the user equipment 30 to the reserved BWP of the cell corresponding to the user equipment 30.
Specifically, in step S5, the method further includes that the base station detects whether the high-priority service triggered by the user equipment 30 is a small-bandwidth high-priority service or a large-bandwidth high-priority service.
Referring to fig. 5, preferably, when the high-priority service triggered by the user equipment 30 is a high-bandwidth high-priority service, the reserved BWP of the cell corresponding to the user equipment 30 needs to be expanded. Specifically, in step S9, when the base station 10 detects that the high-priority service triggered by the user equipment 30 is the high-bandwidth high-priority service, before the base station 10 issues the reserved BWP of the cell corresponding to the user equipment 30, the base station 10 expands the reserved BWP according to the required amount of the high-bandwidth high-priority service of the user equipment 30.
Further, the base station 10 expands the reserved BWP according to the demanded amount of the high-bandwidth high-priority service of the user equipment 30, including the following steps:
s901, the base station 10 switches the currently activated BWP of the user equipment 30 occupying the BWP resource to be subjected to volume expansion and reservation to the initial BWP or the dedicated BWP;
s903, the base station 10 expands the reserved BWP in a left-right widening mode.
Specifically, since each reserved BWP is allocated with only resources with a certain bandwidth, when it is determined that the reserved BWP resources can satisfy the high priority service triggered by the current user equipment 30, the reserved BWP is directly issued to the user equipment 30, and the currently active BWP is switched to the reserved BWP. When the reserved BWP resource is determined to be smaller than the priority service requirement, the user equipment 30 occupying the to-be-expanded BWP resource needs to be switched from the currently activated BWP to another BWP, vacate the resource to the reserved BWP, and then expand the capacity of the reserved BWP. For example: vacate the left resources of the reserved BWP according to the above mechanism, and then expand to the reserved BWP plus the left resources of the reserved BWP. And when judging that the left resource of the vacated BWP reserved resource and the total resource of the reserved BWP can meet the requirement of the high-priority service, expanding the left resource of the reserved BWP. If the high priority service requirement still cannot be met, the execution continues to vacate the reserved BWP right resource, and then expand to the reserved BWP plus the reserved BWP left resource plus the reserved BWP right resource to meet the high priority service requirement triggered by the current user equipment 30. The capacity expansion of the reserved BWP is carried out by adopting a mode of widening left and right.
Referring to fig. 5, in the present embodiment, when the base station 10 does not detect that the user equipment 30 triggers the high priority service, the currently active BWP of the user equipment 30 is kept unchanged. It is understood that the base station 10 loops to continue detecting in step S5 if it does not detect that the user equipment 30 triggers the high priority traffic; and neither of steps S1 nor S3 is affected.
In a specific embodiment, in step S5, it is determined whether the user equipment 30 triggers the high priority service, and the specific determination manner includes the following manners:
firstly, the base station 10 and the core network perform cooperative judgment: specifically, according to the actual conditions, such as clustering and disaster emergency, a certain service or certain services are configured in advance and are definitely designated as high-priority services to the core network, and when the user equipment 30 triggers the high-priority services, the core network can judge that the current service is the high-priority service; the base station 10 is then informed to allocate a reserved BWP. The notification mode from the core network to the base station 10 includes modifying a request signaling by using a PDU (Protocol data Unit) carrying high priority service reserved BWP resource indication information.
And secondly, judging based on a certain service quality index, specifically, judging that the service meeting a certain condition is a high-priority service by a core network. For example, a certain type of traffic whose ARP (Allocation and Retention Priority) value is lower than a certain set value is determined as a high Priority traffic. When the user equipment 30 triggers the high priority service requirement, the core network determines that the high priority service is the high priority service, and then informs the base station 10 to allocate the reserved BWP. The notification mode from the core network to the base station 10 includes modifying a request signaling through a PDU (Protocol data Unit) carrying high priority service use reservation BWP resource indication information.
And thirdly, judging based on a plurality of service quality indexes, specifically, judging that the service meeting certain conditions is a high-priority service by a core network. For example, a multi-class service in which an ARP (Allocation and Retention Priority) value is lower than a certain set value and belongs to a Guaranteed Bit Rate (GBR) and the GBR is higher than 4.5Mbps is determined as a high-Priority service. When the user equipment 30 triggers the high priority service demand, the core network judges it to be a high priority service and then informs the base station 10 to allocate the reserved BWP. The notification mode from the core network to the base station 10 includes modifying a request signaling through a PDU (Protocol data Unit) carrying high priority service use reservation BWP resource indication information.
In the above method, the base station plans the BWP resources such as the reserved BWP, the initial BWP, the dedicated BWP, and the active BWP, and allocates different reserved BWPs for different cells within the multiplexing distance range, so that the base station 10 reasonably plans the BWP resources based on the base station 10 when the user equipment 30 is in the high-priority service and the current active BWP resources of the user equipment 30 are insufficient for responding to the high-priority service, thereby ensuring and improving the service quality of the high-priority service of the user equipment 30.
The above examples merely represent preferred embodiments of the present invention, which are described in more detail and detail, but are not to be construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications, such as combinations of different features in various embodiments, may be made without departing from the spirit of the invention, and these are within the scope of the invention.
