Background
Currently, in order to meet the service requirements of specific users, 5G (5 th Generation Mobile Communication Technology, fifth generation mobile communication technology) introduces a network slicing function. The network slice of the wireless network refers to PRB (Physical Resource Block ) reservation, which can be achieved by the algorithmic function of the scheduler. The bandwidth of the network slice is composed of a dedicated bandwidth, a priority bandwidth and a shared bandwidth, and is set according to the proportion of occupying the cell bandwidth, so that the bandwidth of the network slice is often different from the cell bandwidth, and the bandwidth of the network slice is not perceived by the terminal.
The minimum scheduling granularity of the base station when using the frequency domain resource scheduling Type0 for resource scheduling is RBG (Resource Block Group ), and the scheduling of the frequency domain resource is realized by a combination of bitmap and RBG.

Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments may be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art.
Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus a repetitive description thereof will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software or in one or more hardware modules or integrated circuits or in different networks and/or processor devices and/or microcontroller devices.
The present disclosure relates to the RBG configuration process shown in fig. 1, which, as shown in fig. 1, involves the following processes:
in step S102, the terminal accesses the network;
in step S104, the base station configures the bandwidth of BWP and parameters of RBG;
in step S106, the base station and the terminal determine the size of the RBG according to the BWP bandwidth and the RBG parameters;
in step S108, the base station and the terminal schedule and receive using the RBG;
in step S110, it is determined whether the BWP bandwidth interval is changed, if so, step S112 is executed, and if not, step S114 is executed;
in step S112, the RBG value is updated according to the RBG corresponding to the BWP bandwidth interval, and the base station and the terminal use the new RBG for scheduling and receiving, and return to and execute step S106;
In step S114, the original RBG continues to be validated.
In the RBG configuration process shown in fig. 1, a terminal accesses a network, interacts with the network, and reports the bandwidth supported by the terminal;
the base station configures BWP for the terminal through RRC (Radio Resource Control ) information according to the bandwidth supported by the terminal and the bandwidth of the carrier wave reported by the terminal, wherein the BWP configuration comprises the bandwidth of the BWP and RBG size type parameters;
finally, the size of the resource scheduling minimum granularity RBG is determined by the parameters in the following table 1, and there are 4 BWP bandwidth intervals, which correspond to different RBG values respectively:
TABLE 1
After determining the BWP size and the RBG size type, the base station will schedule resources according to the RBG size and bitmap when using the frequency domain resource scheduling type 0, and the terminal will receive according to the RBG size and bitmap indication.
Only when BWP bandwidth interval changes or RBG size types change, the RBG size changes, otherwise the original RBG is effective all the time;
in the network slice scenario, the bandwidth of the network slice is set and evaluated according to the proportion of the sum of the dedicated bandwidth, the priority bandwidth and the shared bandwidth to the cell bandwidth, the bandwidth of the network slice is determined through the algorithm of the scheduler, and the base station does not need to inform the terminal of the information such as the bandwidth of the network slice, so that the terminal does not actually perceive the bandwidth of the network slice. This can cause problems for scheduling of terminals, such as: the cell bandwidth is 273 RBs (Resource Block), the sum of the dedicated bandwidth, the priority bandwidth and the shared bandwidth of the network slice accounts for 20% of the total proportion of the dedicated bandwidth, i.e. 54 RBs, while the base station and the terminal still schedule and receive according to RBG size=16 (according to the above table 1, the cell bandwidth 273 corresponds to a bandwidth interval of 145-275, the RBG size corresponding to the bandwidth interval is 16), so that the same time slot can only schedule at most 3 terminals, and other terminals need to wait for the next time slot to schedule; or the cell bandwidth is 273 RBs, the sum of the dedicated bandwidth and the priority bandwidth of the network slice partially occupies 10%, that is, 27 RBs, so that 16×1=16 or 16×2=32 RBs will be occupied during scheduling, that is, the sum of the dedicated bandwidth and the priority bandwidth of the network slice is actually 11 or more than 5 less than the sum of the dedicated bandwidth and the priority bandwidth, which results in low scheduling accuracy and may affect the use experience of other common users. Therefore, a network slice-based RBG configuration method is needed to improve scheduling accuracy, and avoid affecting the use experience of other common users on the basis of reducing the waiting time delay of network slice users.
Fig. 2 is a flowchart illustrating a network slice-based RBG configuration method according to an exemplary embodiment of the present disclosure, which may be performed by a network-side device, which refers to a device performing resource allocation and data transmission and reception, for example, an evolved NodeB (base station) in an LTE system, and a base station NodeB and RNC (Radio Network Controller) in a UMTS system. As shown in fig. 2, the method includes:
in step S202, bandwidth information of a network slice of the terminal is acquired;
in an exemplary embodiment, the network slice of the terminal may refer to a network slice to which the terminal signs up. In order to obtain the bandwidth information of the network slice, the subscription information of the network slice of the terminal can be queried first to obtain the Identification (ID) of the network slice, so that the bandwidth information of the network slice can be obtained according to the identification of the network slice. The bandwidth information of the network slice may refer to a bandwidth size of the network slice, where the bandwidth size may include a dedicated bandwidth (also referred to as a exclusive bandwidth), a priority bandwidth, and a shared bandwidth of the network slice.
In step S204, determining a target RBG value corresponding to the network slice according to the bandwidth information and the cell bandwidth of the network slice;
In an exemplary embodiment, the bandwidth of the network slice may be compared with the cell bandwidth, whether the bandwidth of the network slice and the cell bandwidth are in the same bandwidth interval is determined, a target RBG value corresponding to the network slice is determined according to the comparison result, and if the two are not in the same bandwidth interval, the RBG value corresponding to the cell bandwidth is not used as the target RBG value, but the target RBG value is determined according to the actually transmitted bandwidth of the network slice, wherein the target RBG value is the RBG value used by the terminal of the user of the network slice.
In step S206, if the target RBG value is different from the RBG value corresponding to the cell bandwidth, the terminal is notified to update the RBG value.
In an exemplary embodiment, the RBG value corresponding to the cell bandwidth is an RBG value determined according to a mapping relationship between the RBG size defined by 3GPP and the cell bandwidth, which is shown in table 1 above. When the target RBG value is different from the RBG value corresponding to the cell bandwidth, the network slice is indicated to actually transmit more or less than the cell bandwidth, so in the embodiment of the disclosure, the terminal is informed to update the RBG value when the target RBG value is different from the RBG value corresponding to the cell bandwidth. For example, the terminal may be notified to update the RBG value by sending an RBG update message to the terminal, and since both the network side device and the terminal may store the mapping relationship between the bandwidth interval and the RBG value, the RBG update message sent by the network side device to the terminal may be only used to indicate the bandwidth actually transmitted by the network slice, so that after receiving the notification message, the terminal may determine the target RBG value according to the bandwidth actually transmitted by the network slice, and update the original RBG value (i.e., the RBG value corresponding to the cell bandwidth) of the terminal to the target RBG value.
According to the RBG configuration method based on the network slice, the target RBG value corresponding to the network slice is determined according to the bandwidth of the network slice and the cell bandwidth, when the target RBG value is different from the RBG value corresponding to the cell bandwidth, the terminal is informed to update the RBG value, and the purpose of updating the RBG value according to the bandwidth of the network slice is achieved, so that the problem that the scheduling precision is reduced because the RBG value which is the same as the cell bandwidth can only be set by the bandwidth of the network slice can be avoided, the scheduling precision can be improved, the instantaneity is higher, the waiting time delay of a network slice user is reduced, meanwhile, the use experience of other common users (wherein the other common users refer to non-network slice users) can be avoided, the implementation of the scheme is simpler, and any modification of hardware is not needed.
In an embodiment of the present disclosure, the bandwidth information may include: the determining, according to the bandwidth information and the cell bandwidth of the network slice, the target RBG value corresponding to the network slice may include:
and if the sum of the dedicated bandwidth, the priority bandwidth and the shared bandwidth of the network slice is in a different bandwidth interval from the cell bandwidth, determining that the target RBG value is an RBG value corresponding to the bandwidth interval in which the sum of the dedicated bandwidth and the priority bandwidth is located, wherein the different bandwidth interval corresponds to a different RBG value, and no overlapping bandwidth part exists between the different bandwidth intervals.
In an exemplary embodiment, the bandwidth interval may include a plurality of bandwidth intervals corresponding to different RBG values specified in the communication protocol, as four bandwidth intervals corresponding to four different RBG values respectively as listed in table 1 above are defined in 3 GPP.
And determining the target RBG value as the RBG value corresponding to the bandwidth interval where the sum of the special bandwidth and the priority bandwidth of the network slice is located in the bandwidth interval where the sum of the special bandwidth, the priority bandwidth and the shared bandwidth of the network slice is located in the different bandwidth interval from the cell bandwidth, so that the bandwidth used by the network slice can be ensured to meet the priority bandwidth and the shared bandwidth.
In an embodiment of the present disclosure, the bandwidth information may include: the determining, according to the bandwidth information and the cell bandwidth of the network slice, the target RBG value corresponding to the network slice may include:
and if the sum of the dedicated bandwidth, the priority bandwidth and the shared bandwidth of the network slice is in the same bandwidth interval as the cell bandwidth, and the sum of the dedicated bandwidth and the priority bandwidth is also in the same bandwidth interval as the cell bandwidth, determining that the target RBG value is the RBG value corresponding to the cell, wherein different bandwidth intervals correspond to different RBG values, and no overlapping bandwidth part exists between the different bandwidth intervals.
And determining the target RBG value as an RBG value corresponding to the cell when the sum of the dedicated bandwidth, the priority bandwidth and the shared bandwidth of the network slice is in the same bandwidth interval as the cell bandwidth and the sum of the dedicated bandwidth and the priority bandwidth is also in the same bandwidth interval as the cell bandwidth, wherein in the case, the actual transmission bandwidth of the network slice is not much different from the cell bandwidth and the difference between the dedicated bandwidth and the priority bandwidth of the network slice and the cell bandwidth is not much, and on the basis, the RBG value corresponding to the cell bandwidth is still used as the target RBG value, thereby meeting the requirements of the dedicated bandwidth and the priority bandwidth of the network slice, and not causing configuration of excessive bandwidths for the network slice and not reducing the scheduling precision. In this case, the network-side device does not need to inform the terminal to update the RBG value.
In an embodiment of the present disclosure, the bandwidth information may include: the determining, according to the bandwidth information and the cell bandwidth of the network slice, the target RBG value corresponding to the network slice may include:
if the sum of the dedicated bandwidth, the priority bandwidth and the shared bandwidth of the network slice is in the same bandwidth interval as the cell bandwidth, and the sum of the dedicated bandwidth and the priority bandwidth is in a different bandwidth interval from the cell bandwidth, judging whether the terminal has the requirement of using the shared bandwidth;
If the terminal has the requirement of using the shared bandwidth, determining the target RBG value as the RBG value corresponding to the cell bandwidth;
if the terminal does not have the requirement of using the shared bandwidth, determining the target RBG value as an RBG value corresponding to a bandwidth interval in which the sum of the dedicated bandwidth and the priority bandwidth is located;
wherein, different bandwidth intervals correspond to different RBG values, and no overlapped bandwidth part exists between the different bandwidth intervals.
In an exemplary embodiment, if the sum of the dedicated bandwidth, the priority bandwidth, and the shared bandwidth of the network slice and the cell bandwidth are in different bandwidth intervals, determining that the bandwidth actually transmitted by the network slice is the sum of the dedicated bandwidth and the priority bandwidth of the network slice; if the special bandwidth, the priority bandwidth, the shared bandwidth and the cell bandwidth of the network slice are in the same bandwidth interval, the sum of the special bandwidth and the priority bandwidth of the network slice and the cell bandwidth are in different bandwidth intervals, and the terminal has no use requirement for the shared bandwidth, determining that the bandwidth actually transmitted by the network slice is the sum of the special bandwidth and the priority bandwidth of the network slice.
In the case that the sum of the dedicated bandwidth, the priority bandwidth and the shared bandwidth of the network slice is in the same bandwidth interval as the cell bandwidth, and the sum of the dedicated bandwidth and the priority bandwidth is in a different bandwidth interval from the cell bandwidth, the difference between the sum of the dedicated bandwidth and the priority bandwidth of the network slice and the cell bandwidth is larger, so in the embodiment, whether the terminal has a use requirement for the shared bandwidth needs to be judged, if the terminal has a use requirement for the shared bandwidth, the target RBG value is determined as the RBG value corresponding to the cell bandwidth, and the use requirement for the dedicated bandwidth, the priority bandwidth and the shared bandwidth of the network slice can be satisfied; if the terminal does not have the use requirement for the shared bandwidth, the target RBG value is determined to be the RBG value corresponding to the bandwidth interval where the sum of the dedicated bandwidth and the priority bandwidth is located, so that the use requirements of the dedicated bandwidth and the shared bandwidth of the network slice can be met, and excessive bandwidth configuration for the terminal is not caused.
In an exemplary embodiment, the network side device may calculate, according to a preset rule (hereinafter also referred to as a network slice RBG algorithm), a target RBG value corresponding to a network slice, and determining, according to bandwidth information and a cell bandwidth of the network slice, the target RBG value corresponding to the network slice may include:
