The base station 10 is in contact with the peripheral base stations 20 and the user equipment 30, respectively. The base station 10 and the peripheral base stations 20 are bidirectional information interaction; the base station 10 and the ue 30 issue information in one direction, that is, the base station 10 issues information to the ue 30.
Referring to fig. 1, fig. 3 and fig. 4, the base station 10 includes a first XN interface 11, a summary module 13, a first configuration module 15, a first signaling generation module 17 and a first signaling transceiver module 19. The peripheral base station 20 includes a second XN interface 21, a second configuration module 22, a second signaling generation module 23, and a second signaling transceiver module 25.
In this embodiment, after the first XN interface 11 and the second XN interface 21 configure XN connection, an XN link between the base station 10 and the peripheral base station 20 is established, and the XN link is used for transmitting/receiving BWP allocation information between the base station 10 and the peripheral base station 20 periodically or when BWP changes.
The summarizing module 13 is configured to count and summarize BWP allocation information of the neighboring base stations 20 and compare the BWP allocation information of the neighboring base stations 20 with all BWP allocation information of the base stations 10.
The first configuration module 15 is configured to configure BWP allocation information of the base station 10; and is further configured to reconfigure all or part of the BWP allocation information of the base station 10 that is contained in the BWP allocation information of the neighboring base stations 20 when the summarizing module 13 compares that all or part of the BWP allocation information of the base station 10 is contained in the BWP allocation information of the neighboring base stations 20.
The second configuration module 22 is used for configuring BWP allocation information of the peripheral base station 20.
Referring to fig. 1, in the present embodiment, when the base station 10 interacts with the peripheral base station 20 for bidirectional BWP allocation information, there are the following two interaction methods:
the first mode is as follows: the first signaling generation module 17 and the second signaling generation module 23 are both configured to generate XN signaling, and a field for performing BWP information interaction is added to each of the two XN signaling generated by the first signaling generation module 17 and the second signaling generation module 23, and the first signaling transceiver module 19 and the second signaling transceiver module 25 transmit the fields to each other, so as to perform BWP allocation information interaction.
The second way is: one of the first signaling generation module 17 and the second signaling generation module 23 is used for BWP information signaling; the other of which is used to generate BWP information acknowledgment signaling. That is, the first signaling generating module 17 and the second signaling generating module 23 respectively create a BWP signaling and a BWP signaling confirmation, and one of the first signaling transceiver module 19 and the second signaling transceiver module 25 is used for transceiving the BWP signaling, and the other is used for transceiving the BWP signaling confirmation to transmit the BWP allocation information, thereby implementing information interaction.
Referring to fig. 2 and 5, the user equipment 30 includes a receiving module 31, where the receiving module 31 is configured to receive the initial BWP and the dedicated BWP issued by the base station 10.
Specifically, the first signaling generation module 17 is further configured to generate a MIB message, a SIB message, an RRC reconfiguration message, and a DCI message. The first signaling transceiver module 19 is further configured to issue the initial BWP and the dedicated BWP to the user equipment 30 through any one of the MIB message, SIB message, RRC reconfiguration message or DCI message.
The method for adaptively adjusting BWP configuration by a base station in the system for adaptively adjusting BWP configuration according to the present application is described in detail with reference to fig. 6, and includes the following steps executed in sequence:
s3, configuring XN connection between the base station 10 and the peripheral base station 20 through an XN interface according to the service requirement and the coverage distance;
s5, establishing an XN link between the base station 10 and the peripheral base station 20;
s7, the base station 10 issues an initial BWP and a special BWP to the user equipment 30;
s9, the BWP allocation information is transmitted between the base station 10 and the peripheral base station 20 periodically through an XN link or when the BWP changes; the BWP allocation information includes an initial BWP and a dedicated BWP;
s11, after receiving the BWP allocation information of the neighboring base station 20, the base station 10 counts and summarizes the BWP allocation information of the neighboring base station 20;
s13, the bs 10 compares the BWP allocation information of the neighboring bss 20 with all the BWP allocation information of the bss 10, and if all or part of the BWP allocation information of the bss 10 is contained in the BWP allocation information of the neighboring bss 20, the bss 10 reconfigure all or part of the BWP allocation information contained in the BWP allocation information of the neighboring bss 20 to keep it different from the BWP allocation information of the neighboring bss 20;
s15, the base station 10 transmits the latest BWP allocation information to the neighboring base stations 20.
In this embodiment, the initial BWP is the BWP randomly used by the user equipment 30 in the initial access phase. Dedicated BWP is mainly used for data traffic transmission. Both the base station 10 and the peripheral base station 20 are able to configure the initial BWP and the dedicated BWP. That is, the base station 10 and the neighboring base stations 20 are both configured with BWP allocation information. The base station 10 and the neighboring base station 20 can exchange BWP allocation information through BWP information signaling and BWP information confirmation signaling.
The above method enables the base station 10 to receive the BWP allocation information of the neighboring base stations 20, and perform statistical aggregation and comparison, and when all or part of the BWP allocation information of the base station 10 is contained in the BWP allocation information of the neighboring base stations 20, the base station 10 reconfigures all or part of the BWP allocation information identical to that of the neighboring base stations 20 to keep it different from that of the neighboring base stations 20. Thus, the base station can adaptively adjust the BWP configuration, reduce interference in the 5G mobile communication system, and improve user perception.
Specifically, in step S13, the method further includes ending if all BWP allocation information of the base station 10 is not contained in the BWP allocation information of the neighboring base stations 20. I.e. all BWP allocation information of the base station 10 is different from the BWP allocation information of the neighboring base stations 20, the method step of adaptively adjusting the BWP configuration by the base station is not needed.
In step S15, the base station 10 further transmits the latest BWP allocation information to the neighboring base stations 20 through the BWP information creation signaling and the BWP information confirmation signaling.
In steps S9 and S15, the BWP allocation information is transmitted between the base station 10 and the neighboring base station 20 via the XN link in two ways:
first, the base station 10 and the peripheral base station 20 transmit BWP allocation information by adding a field for BWP information interaction to the configured XN signaling base station according to the XN signaling configured according to the service requirement and/or the coverage distance.
Second, the base station 10 and the neighboring base station 20 transmit BWP allocation information to each other by creating BWP information signaling and BWP information confirmation signaling.
In step S7, the method specifically includes that 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.
In step S3, the service requirement is that the number of successful handover times between the base station 10 and one of the peripheral base stations 20 exceeds a preset threshold within a predetermined time; the coverage distance is the closest site relationship between the base station 10 and the neighboring base stations 20 determined from the geographical location.
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.
