It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The resource allocation method provided by the application can be applied to an application environment shown in fig. 1, and the access network device 100 is in communication connection with the user device 200. The user device 200 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, portable wearable devices, and the like. The access network device may be, but not limited to, a macro base station, a micro base station, a small base station, or other base station devices, and may be a base station (Base Transceiver Station, BTS) in global mobile communications (Global System of Mobile communication, abbreviated GSM) or code division multiple access (Code Division Multiple Access, abbreviated CDMA), a base station (NodeB, abbreviated NB) in wideband code division multiple access (Wideband Code Division Multiple Access, abbreviated WCDMA), an evolved base station (Evolutional Node B, abbreviated eNB, or eNodeB) in LTE, or a relay station or an access point, or a base station in future 5G network, a customer premise equipment (Customer Premise Equipment, abbreviated CPE), a narrowband internet of things base station, or the like.
In one embodiment, as shown in fig. 2, a resource allocation method is provided, which is illustrated by taking an example that the method is applied to the access network device in fig. 1, and includes:
s101, determining whether downlink data to be transmitted comprises state report request information of the downlink data; the status report request information is used for indicating the user equipment UE to return a status report of the downlink data to the access network device, and the status report is used for indicating whether the UE completely receives the downlink data.
The UE may be a terminal accessing the access network device in the current scheduling period, and may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, portable wearable devices, and the like.
The downlink data may be downlink traffic data to be sent to the UE by the access network device, or may be downlink control data, which is not limited herein.
The access network device may determine, before sending the downlink data, whether the downlink data includes status report request information of the downlink data. The status report request information is used for indicating the UE to return the status report of the downlink data to the access network equipment. The status report request information may be a character of a preset field in the downlink data, or may be a data packet included in the downlink data, which is not limited herein. The access network device may determine whether the downlink data includes the status report request information according to the value of the preset field, or may determine the downlink data according to the packet identifier corresponding to the status report request information, which is not limited herein. Optionally, the access network device may query the value in the status flag bit in the downlink data through the RLC layer in the access network device; if the value in the status flag bit is set to a preset status value, determining that the downlink data includes status report request information. The status flag bit may be a POLL bit in the downlink data, and if the value in the POLL bit is 1, the access network device may consider that the downlink data includes status report request information; if the value in the POLL bit is 0, the access network device may consider that the downlink data does not include the status report request information.
The status report may be used to characterize whether the UE has received the downlink data completely. The status report may include the size of the data amount of the received downlink data, the identifier of the data packet in the received downlink data, and the receiving order of each data packet in the received downlink data, which is not limited herein. If the downlink data received by the UE includes the status report request information, the UE may process the downlink data, generate a status report corresponding to the downlink data according to a preset rule, and then send the status report to the access network device. If the downlink data received by the UE does not include the status report request information, the status report does not need to be sent to the access network equipment.
And S102, if so, indicating the PUSCH resource matched with the preset data quantity to the UE according to the preset data quantity of the status report so that the UE can send the status report based on the PUSCH resource.
Based on the above steps, if the access network device determines that the downlink data includes the status report request information, the access network device may determine that the UE needs PUSCH resources to return the status report.
Further, the access network device may obtain a preset data amount of the status report, where the preset data amount is related to a data amount of the status report, and the access network device may determine the preset data amount according to the historical status report returned by the UE, and may also estimate the data amount of the status report, so that PUSCH resources determined by the access network device according to the preset data amount may meet a transmission requirement of the status report.
The access network equipment can determine the size of the PUSCH resource required by the UE according to the preset data quantity; and then configuring the PUSCH resource for the UE in the available resources according to the size of the PUSCH resource. The available resource may be a dedicated PUSCH resource configured by the access network device for the UE, and may be a common PUSCH resource configured by the access network device, which is not limited herein. The access network device may determine a PUSCH resource matching the size of the PUSCH resource, and then send configuration information of the PUSCH resource to the UE, so that the UE may send a status report through the PUSCH resource.
The access network device may instruct the PUSCH resource to the UE when sending the downlink data, or may instruct the PUSCH resource to the UE after sending the downlink data, which is not limited herein. Optionally, the access network device may delay a preset duration after sending the downlink data to the UE, and then indicate, to the UE, PUSCH resources matching the preset data amount according to the preset data amount of the status report.
The preset duration may be determined by an air interface transmission duration of the downlink data and/or a processing duration of the downlink data by the UE. The access network equipment can acquire the average time length of the UE for processing the downlink data, and then the average time length is determined to be a preset time length; or the access network equipment can also determine the air interface transmission duration according to the distance between the UE and the access network equipment, and then determine the preset duration according to the air interface transmission duration; the access network device may determine the air interface transmission duration as a preset duration, or may determine 2 times or half of the air interface transmission duration as a preset duration, which is not limited herein.
After the access network equipment sends downlink data, delaying the preset time length and indicating the PUSCH resource to the UE, so that the UE can receive the indication information of the PUSCH resource after the UE is ready for the status report, and the situation that the UE sends an empty message in the PUSCH resource under the condition that the UE is not ready for the status report is avoided, and the transmission of the status report is influenced.
According to the resource allocation method, the access network equipment determines whether the downlink data to be sent comprises the state report request information of the downlink data or not; if yes, according to the preset data quantity of the state report, indicating the PUSCH resource matched with the preset data quantity to the UE so that the UE can send the state report based on the PUSCH resource; the status report request information is used for indicating the user equipment UE to return a status report of downlink data to the access network device, and the status report is used for indicating whether the UE completely receives the downlink data. Because the access network equipment determines whether the downlink data comprises the status report request information, whether the UE needs the PUSCH resource or not can be judged to return the status report; further, the access network equipment indicates the PUSCH resource matched with the preset data volume of the status report to the UE, so that the UE can obtain the PUSCH resource without initiating actions such as a random access request to the access network equipment, the sending flow of the status report is simplified, the transmission efficiency of the status report is improved, and the transmission delay of the status report is reduced.
Fig. 3 is a flowchart of a resource allocation method in an embodiment, where the embodiment relates to a specific manner in which the access network device indicates PUSCH resources to the UE, and on the basis of the above embodiment, as shown in fig. 3, the step S102 includes:
s201, generating a Buffer Status Report (BSR) of the UE through a Radio Link Control (RLC) layer of access network equipment according to a preset data volume of the status report; wherein, the BSR carries a preset data amount of the status report.
The access network device may include a radio link control (Radio Link Control, RLC for short) layer and a medium intervention control (Media Access Control, MAC for short) layer, where the RLC layer may be used to implement segmentation, sufficiency, retransmission processing, and the like of transmission data; the MAC layer may be used to implement air interface scheduling, such as scheduling PUSCH resources for UEs. In addition, the access network device may further include a physical layer, a packet data convergence protocol (Packet Data Convergence Protocol, abbreviated PDCP) layer, and the like.
The access network device may generate a buffer status report (Buffer Status Report, abbreviated BSR) of the UE through the RLC layer according to a preset data amount of the status report. The BSR carries a preset data amount of a status report, and is used for allocating PUSCH resources based on the BSR by the MAC.
Specifically, the RLC layer may determine, from the historical BSRs sent by the UE to the access network device, a historical BSR that matches the preset data amount, and determine the historical BSR as the BSR generated by the current access network device. Optionally, the access network device may further add a preset data amount and identification information of the UE to a preset BSR template through the RLC layer, so as to generate a BSR corresponding to the UE. The preset BSR template may further include a UE identifier, and the access network device may add the UE identifier and a preset data amount to the BSR template, so that the MAC layer may configure PUSCH resources for the UE corresponding to the UE identifier based on the preset data amount.
S202, the BSR is sent to a media intervention control MAC layer of the access network equipment through the RLC layer.
S203, determining the size of the PUSCH resource based on the BSR through the MAC layer, and indicating the PUSCH resource matched with the size of the PUSCH resource to the UE.
Further, the access network device may send the BSR to a media intervention control MAC layer of the access network device through the RLC layer. After the MAC layer receives the BSR, the size of PUSCH resources required by the UE may be determined according to a preset data size carried in the BSR. The size of the PUSCH resources may be equal to or greater than a preset data amount. Further, the MAC layer may determine a PUSCH resource matching the size of the PUSCH resource among available PUSCH resources, and indicate the PUSCH resource to the UE.
According to the resource allocation method, after the access network equipment determines that the downlink data comprises the status report request information, the access network equipment can predict that the UE needs the PUSCH resource and generate the BSR of the UE through the RLC layer, so that the MAC layer can automatically allocate the PUSCH resource for the UE after receiving the BSR, and the resource allocation is not needed to be carried out after the BSR sent by the UE is received, the allocation process of the PUSCH resource is accelerated, and the transmission delay of the status report is reduced.
Fig. 4 is a flowchart of a resource allocation method in an embodiment, where the embodiment relates to a specific manner of determining a preset duration by an access network device, and on the basis of the foregoing embodiment, as shown in fig. 4, the method further includes:
s301, marking historical transmission time of historical downlink data through an MAC layer of access network equipment.
When the access network device determines the preset duration, the access network device may determine the duration according to a transmission process of historical downlink data of the UE. The access network device may record a historical transmission time of one of the downlink data through the MAC layer. The history transmission time may be a time when the RLC layer transmits to the MAC layer, may be a time when downlink data is encapsulated, or may be a time when the MAC layer transmits to the physical layer.
S302, receiving Acknowledgement (ACK) information returned by the UE based on the historical downlink data through the MAC layer, and acquiring the historical receiving moment of the ACK information.
After the access network device sends the historical downlink data to the UE, the UE may return acknowledgement information (ACK) of the downlink data to the MAC layer, where the ACK information may be a set of control characters, and is used to inform the access network device that the data sent by the access network device has been received. The access network device can monitor whether the ACK information is received or not through the MAC layer, and determine the historical receiving moment of the ACK information.
S303, calculating a difference value between the historical sending time and the historical receiving time through the MAC layer, and determining the difference value as a preset duration.
Based on the steps, the access network device can calculate the difference between the historical sending time and the historical receiving time through the MAC layer, wherein the difference comprises the air interface transmission time length for transmitting data between the access network device and the UE, and also comprises the processing time length for processing the historical downlink data by the UE to obtain the ACK information. Therefore, the access network device may determine the difference value as a preset duration corresponding to the UE.
S304, the preset duration is sent to the RLC layer of the access network equipment through the MAC layer.
Further, the access network device may send the calculated preset duration to the MAC layer through the MAC layer, so that when downlink data sent by the access network device to the UE subsequently includes the status report request information, the MAC layer may be controlled to configure PUSCH resources based on the preset duration.
According to the resource allocation method, the access network equipment determines the preset duration corresponding to the UE according to the transmission process of the historical downlink data of the UE, so that the PUSCH resource can be indicated to the UE after the preset duration is delayed after the downlink data is transmitted to the UE, the UE can receive the indication information of the PUSCH resource after the state report is ready, and the phenomenon that the UE transmits a null message in the PUSCH resource under the condition that the state report is not ready to influence the transmission of the state report is avoided; in addition, the access network equipment determines the preset duration of each UE according to the transmission process of the historical downlink data of the UE, so that the preset duration can be more matched with the downlink data processing duration of the UE, and the reliability of the UE transmitting the status report is ensured to be improved.
