Those skilled in the art will appreciate that the number of base stations 101, UEs 102 and BDs 103 in fig. 1 is merely illustrative, and there may be any number of base stations, UEs and BDs, according to actual needs. The embodiments of the present disclosure are not limited thereto.
Under the system architecture, the embodiment of the present disclosure provides a converged communication method, which can be executed by any electronic device with computing processing capability. In some embodiments, the converged communication method provided in the embodiments of the present disclosure may be performed in the base station 101 shown in fig. 1.
Fig. 2 shows a flowchart of a converged communication method in an embodiment of the present disclosure, and as shown in fig. 2, the converged communication method provided in the embodiment of the present disclosure includes the following steps S201 to S204.
S201, sending a reference signaling to a backscatter communication device BD and a user equipment UE in a downlink subframe of a current frame, wherein the reference signaling carries a reserved uplink subframe identifier, and the reserved uplink subframe identifier is used for indicating the UE to suspend sending UE data in an uplink subframe corresponding to the reserved uplink subframe identifier and indicating the BD to send BD data in the uplink subframe.
The data of the BD is communication data generated by the BD, and the data of the UE is communication data generated by the UE; the reference signaling is sent by the base station to the BD and the UE, and is used to instruct the BD and the UE to transmit communication data according to the reference signaling, where the reference signaling may include one or more of characters, letters, numbers, symbols, and the like, and the reference signaling is not limited in this disclosure, for example, the reference signaling is Stop Sending (subframe N), where subframe N is a reserved uplink subframe identifier, and N represents a subframe number of an uplink subframe corresponding to the reserved uplink subframe identifier.
S202, receiving BD data in an uplink subframe corresponding to the reserved uplink subframe identification.
And after receiving the reference signaling sent by the base station, the BD transmits BD data in the uplink subframe corresponding to the reserved uplink subframe identifier, after receiving the reference signaling sent by the base station, the UE suspends sending the UE data in the uplink subframe corresponding to the reserved uplink subframe identifier, and the base station receives the BD data in the uplink subframe corresponding to the reserved uplink subframe identifier.
S203, determining the physical resource block PRB occupancy rate of the BD data in the uplink subframe.
And the PRB occupancy rate is the occupancy rate of the BD data in the PRB of the uplink subframe corresponding to the reserved uplink subframe identifier. The BD data may include, but is not limited to, one or more of a duty cycle of the BD, an ID (identification number) of the BD, a total data amount of the BD, a transmitted data amount of the BD, and BD communication data.
And S204, configuring a target reserved uplink subframe for transmitting BD data for the BD according to the PRB occupancy rate.
According to the method, the resource allocation and reservation are carried out according to the PRB occupancy rate, the preferential uploading of BD data can be guaranteed, and the time delay of the BD is reduced; by indicating the UE to suspend sending UE data in the uplink subframe corresponding to the reserved uplink subframe identifier, only BD data can be received in a certain time-frequency resource, so that mutual interference during the fusion communication of the backscatter Internet of things and the cellular network can be reduced, the demodulation difficulty of cellular network signals and backscatter Internet of things signals is effectively lowered, and the computation amount is reduced.
In one embodiment, the BD data includes a duty cycle of the BD; according to the PRB occupancy rate, reserving an uplink subframe for a target for transmitting BD data, which comprises the following steps: and determining the target reserved uplink subframe configured for the BD in the current working period and the next working period according to the PRB occupancy rate in the current working period.
When the PRB occupancy rate is low, the BD indicates that the BD has been transmitted with BD data in the current working period, an uplink subframe does not need to be reserved for a BD configuration target in the current working period, and a reference signaling needs to be sent to the BD and the UE in the next working period of the BD; when the PRB occupancy rate is 100% and the BD data uploaded to the base station is part of the BD data, the base station needs to reserve the uplink subframes for the BD configuration target in the current working period, and if the uplink subframes in the current working period are all configured and the BD data is not transmitted, the base station needs to readjust the configuration strategy.
Fig. 3 shows a flowchart of a method for determining a target reserved uplink subframe configured for a BD in the embodiment of the present disclosure, and in one embodiment, as shown in fig. 3, S203 determines PRB occupancy of physical resource blocks of BD data in the uplink subframe, and the method for determining the target reserved uplink subframe configured for the BD in the current working cycle and the next working cycle according to PRB occupancy in the current working cycle includes the following steps S301 to S303.
S301, under the condition that the PRB occupancy rate is smaller than the first occupancy rate threshold, judging whether the PRB occupancy rate in the current working cycle is larger than or equal to a second occupancy rate threshold, wherein the second occupancy rate threshold is smaller than the first occupancy rate threshold, and if so, executing S302; if not, go to step S303.
The size or the specific value range of the second occupancy threshold is not limited in the embodiment of the present disclosure, for example, the second occupancy threshold is 50%, and the size of the second occupancy threshold may be set according to the deployment location of the base station and the traffic density of the UE. The first occupancy threshold is greater than the second occupancy threshold, and the size or specific value range of the first occupancy threshold is not limited in this disclosure, for example, the first occupancy threshold may be any value within a [90%,100% ] interval, and for example, the first occupancy threshold is 100%.
It should be noted that when the PRB occupancy is smaller than the first occupancy threshold, indicating that the BD data transmission is completed, it is no longer necessary to reserve an uplink subframe for the BD configuration target in the current working cycle, and in the next working cycle of the BD, an uplink subframe corresponding to the reserved uplink subframe identifier is configured for the BD, so as to obtain the working cycle of the BD, the ID of the BD, the total data volume of the BD, and the BD data.
S302, if the PRB occupancy rate in the current working cycle is greater than or equal to the second occupancy rate threshold value, configuring an uplink subframe corresponding to the reserved uplink subframe identifier for the BD in the next working cycle, and using the uplink subframe as a target reserved uplink subframe to transmit BD data.
Whether the PRB occupancy rate in the current working cycle is greater than or equal to the second occupancy rate threshold value or not indicates that the occupancy rate of the uplink subframe corresponding to the uplink subframe identifier reserved in the current working cycle occupied by the BD data is high, and the uplink subframe is required to be reserved for a target which is configured for the BD only for transmitting the data in the next working cycle. According to the method, the uplink subframe corresponding to the reserved uplink subframe identification is only used for transmitting BD data, so that mutual interference when the backscatter Internet of things and the cellular network are fused and communicated is reduced, the demodulation difficulty of cellular network signals and backscatter Internet of things signals is effectively lowered, and the calculation amount is reduced.
