Description

Buffer status report BSR reporting method and device and electronic equipment

[ field of technology ]

The present invention relates to the field of wireless communications technologies, and in particular, to a method, an apparatus, and an electronic device for reporting a buffer status report BSR.

[ background Art ]

In the field of wireless communications, reporting a buffer status report (Buffer Status Reporting, BSR) is a way for a user equipment to apply for Resource Blocks (RBs) to a network device. After triggering the BSR, the user equipment may report the BSR to the network device according to the amount of uplink data to be transmitted buffered by the current packet data convergence protocol (Packet Data Convergence Protocol, PDCP) sublayer/radio link control (Radio Link Control, RLC) sublayer. Thus, the network device may schedule RBs for the user device according to the amount of uplink data to be transmitted. If the BSR reported by the ue is 0, the network device will not schedule RBs for the ue. At this time, if the PDCP sublayer/RLC sublayer of the ue receives new uplink data again, the ue triggers a random access procedure because there is no RB available, thereby increasing data transmission delay and affecting data transmission performance of the ue.

The communication system 100 may be a wireless communication system that may operate in an licensed frequency band or an unlicensed frequency band.

It should be noted that the number and the form of the user equipment 102 and the network equipment 101 shown in fig. 1 do not limit the embodiments of the present invention. In different embodiments, the network device 101 may also be connected to a core network device, which is not shown in fig. 1.

It should be noted that, the wireless communication system mentioned in the embodiments of the present invention includes, but is not limited to: narrowband internet of things (Narrow Band-internet of Things, NB-IoT), global system for mobile communications 100 (Global System for Mobile Communications, GSM), enhanced data rates for GSM evolution (Enhanced Data Rate for GSM Evolution, EDGE), wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA), code division multiple access 2000 (Code Division Multiple Access, CDMA 2000), time division synchronous code division multiple access (Timedivision-Synchronization Code Division Multiple Access, TDSCDMA), long term evolution (Long Termevolution, LTE), fifth generation mobile communication systems, vehicular wireless short range communication systems, and future mobile communication systems.

In the embodiment of the present invention, the network device 101 is a device deployed in a radio access network to provide a wireless communication function for the user equipment 102. The network device 101 may include, but is not limited to, a Base Station (BS), a Station (STA), including an Access Point (AP) and a non-AP Station STA, a network controller, a wireless Access Point (TRP) in a mobile switching center or wifi, and the like, and the device that directly communicates with the user device 102 through a wireless channel is typically a Base Station. The base stations may include various forms of macro base stations, micro base stations, relay stations, access points or remote radio units (Remote Radio Unit, RRU), and the like. Of course, the network device 101 with the wireless communication function may also be used to perform wireless communication with the user device 102, which is not limited in this application.

A User Equipment (UE) 102 is a device that provides voice and/or data communication to a User, such as a handheld device, an in-vehicle device, a wearable device, a computing device, or other processing device linked to a wireless modem, with wireless connectivity. Currently, some examples of user equipment 102 are: a Mobile Phone, a tablet, a notebook, a palm, a Mobile internet device (Mobile Internet Device, MID), a wearable device, a Virtual Reality (VR) device, an augmented Reality (Augmented Reality, AR) device, a wireless terminal in industrial control (Industrial Control), a wireless terminal in unmanned (Self Driving), a wireless terminal in teleoperation (Remote Medical Surgery), a wireless terminal in Smart Grid (Smart Grid), a wireless terminal in transportation security (Transportation Safety), a wireless terminal in Smart City (Smart City), a wireless terminal in Smart Home (Smart Home), and the like.

In wireless communication systems, buffer status report (Buffer Status Report, BSR) reporting is very important. The network device may determine, according to the BSR reported by the user device, an uplink data amount to be sent by the user device. Thus, the network device may decide the size of a Resource Block (RB) scheduled to the user device according to the size of the uplink data amount. And by a reporting mechanism of the BSR, the efficient utilization of transmission resources is facilitated.

Fig. 2 is a block diagram of a user equipment according to an embodiment of the present invention. As shown in fig. 2, the user equipment 102 provided by the present invention may include an application layer 1021 and a data link layer 1022. The data link layer 1022 may further include, among other things, a packet data convergence protocol (Packet Data Convergence Protocol, PDCP) sublayer 221, a radio link control (Radio Link Control, RLC) sublayer 222, and a media intervention control (Medium Access Control, MAC) sublayer 223.

In the current BSR reporting method, as shown in fig. 3, the MAC sublayer of the ue detects the amount of uplink data to be transmitted buffered in the PDCP sublayer and the RLC sublayer. If the current uplink data amount to be sent is detected to be 0, a BSR with a value of 0 is reported to network equipment (a base station in the figure). Thus, the network device will stop scheduling RBs for the user device. At this time, after the MAC sublayer receives the uplink data to be transmitted again, the random access is triggered because there is no available RB, which increases the data transmission delay and affects the transmission efficiency.

The present invention has been made to solve the above-mentioned problems. The execution main body of the Buffer Status Report (BSR) reporting method provided by the invention can be the MAC sub-layer of the user equipment.

Fig. 4 is a flowchart of a method for reporting a buffer status report BSR according to an embodiment of the present invention. As shown in fig. 4, the processing steps of the method include:

step 101, after the mac sublayer detects that the BSR trigger condition is satisfied, acquiring a PDCP sublayer and a first uplink data amount to be transmitted in the RLC sublayer.

In the embodiment of the invention, the triggering condition of the BSR can refer to the triggering mechanism of the BSR in the current network. For example, the MAC sublayer may detect that the triggering condition of the BSR is satisfied, for example, by: detecting that uplink data belonging to a higher priority logical channel group arrives; it is also possible that: detecting that new data arrives when any logical channel of the logical channel group has no available data for transmission; it is also possible that: the retransmission BSR Timer retxBSR-Timer times out while there is available data for transmission on some logical channel, etc. The embodiments of the present invention are not limited in this regard.

Further, after the detection that the BSR trigger condition is satisfied, the MAC sublayer may send a data amount query request to the PDCP sublayer and the RLC sublayer through corresponding communication interfaces, respectively. The data query request may be used to query the PDCP sublayer and the RLC sublayer for the amount of uplink data buffered. Further, the MAC sublayer may receive data amount information transmitted by the PDCP sublayer and the RLC sublayer according to the data amount inquiry request, respectively. Thus, the MAC sublayer may determine the PDCP sublayer and the first uplink data amount to be transmitted in the RLC sublayer according to the obtained data amount information.

Step 102, if the first uplink data amount is zero, the MAC sublayer generates a BSR according to the second uplink data amount and reports the BSR to the network device. The second amount of upstream data is a non-zero value.

In the embodiment of the present invention, after determining the first uplink data amount to be sent in the PDCP sublayer and the RLC sublayer, the MAC sublayer may first determine whether the value of the first uplink data amount is zero.

If the value of the first uplink data amount is 0, in order to avoid interruption of RB scheduling of the ue caused by reporting the BSR of the 0 value, at this time, the MAC sublayer may determine the second uplink data amount, and generate the BSR according to the second uplink data amount, and report the BSR to the network device. In the embodiment of the invention, the value of the second uplink data quantity is a non-zero value. The second uplink data amount may be obtained by predicting, by the MAC sublayer, the uplink data amount to be sent in the preset time period according to the current service type.

In the embodiment of the invention, a specific implementation manner of predicting the second uplink data amount by the MAC sublayer according to the current service type is described.

In one possible implementation, first, the MAC sublayer may obtain service indication information from the APP layer. The service indication information may be used to indicate a type of service currently being performed, and an amount of uplink data to be received by the PDCP sublayer and the RLC sublayer within a preset period of time under the current type of service. Therefore, the MAC sublayer can determine the PDCP sublayer and the second uplink data amount to be sent by the RLC sublayer in a preset time period under the current service type according to the service indication information. The preset time period represents a future time length, and the value of the preset time period can be set according to an actual scene.

In another possible implementation, the MAC sublayer may store the service information table in advance. The service information table may maintain a data transmission mode corresponding to each service type, including a data transmission interval between each data packet, a data amount of each transmission, and the like. In such an implementation, first, the MAC sublayer may obtain traffic indication information from the APP layer. The service indication information may be used to indicate the type of service currently being performed. Then, the MAC sublayer may query a locally stored service information table according to a service type, so as to obtain second uplink data amounts to be transmitted by the PDCP sublayer and the RLC sublayer in a preset time period under the service type.

In the two implementations, the specific implementation manner of the MAC sublayer obtaining the service indication information from the APP layer may be a passive receiving manner or an active query manner. In the passive receiving mode, the MAC sublayer may receive service indication information automatically transmitted by the application layer when the service is established. In the active query mode, the MAC sublayer may actively send a service query request to the application layer before reporting the BSR, and further may receive service indication information sent by the application layer according to the service query request.

Further, the second uplink data amount may also be preset. In the embodiment of the present invention, the second uplink data amount may be set to any non-zero value by means of an AT (Attention) command or a fixed code. Therefore, no matter what type of service is currently executed, the MAC sublayer can generate a BSR according to the set second uplink data amount after detecting that the current first uplink data amount is 0, and report the BSR.

It should be noted that, if the value of the first uplink data amount is not 0, the MAC sublayer may generate a BSR according to the first uplink data amount and report the BSR to the network device.

In the above scheme, after detecting that the BSR trigger condition is satisfied, the MAC sublayer of the ue may acquire the PDCP sublayer and the first uplink data amount to be transmitted in the RLC sublayer. If the first uplink data amount is zero, the MAC sublayer may generate a BSR according to the second uplink data amount and report to the network device. The second uplink data volume is a non-zero value obtained by predicting the uplink data volume to be sent in a preset time period by the MAC sub-layer according to the current service type; alternatively, the second amount of upstream data is a predetermined non-zero value. By the scheme, under the condition that the uplink data transmission interval is relatively short, the continuous RB scheduling of the network equipment can be acquired, and the frequent triggering of the random access process due to lack of the RB is avoided, so that the data transmission performance of the user equipment is improved.

For easy understanding, fig. 5 shows a timing diagram of a buffer status report BSR reporting method corresponding to a service type with a data interaction mode of "one-to-one answer mode". By way of example, such traffic types may be, for example, downlink transmission control protocol (Transmission Control Protocol, TCP) traffic, downlink internet packet explorer (Packet Internet Groper, ping) packet traffic, and so on. As shown in fig. 5, the buffer status report BSR reporting method in this case may include:

in step 201, the MAC sublayer of the ue receives downlink data sent by the network device (base station in the figure).

Step 202, the MAC sublayer of the ue sends the received downlink data to the APP layer of the ue.

In step 203, the APP layer of the ue triggers uplink data according to the received downlink data.

In step 204, the MAC sublayer of the ue determines that the first uplink data amount to be transmitted in the PDCP sublayer and the RLC sublayer is 0.

In step 205, the MAC sublayer of the user equipment reports a BSR of non-zero value to the network equipment to maintain RB scheduling.

In step 206, the APP layer of the ue sends uplink data to the MAC sublayer via the PDCP sublayer and the RLC sublayer.

In step 207, the MAC sublayer of the ue sends the received uplink data to the network device.

In the above scheme, when the MAC sublayer of the ue detects that the first uplink data amount buffered in the PDCP sublayer and the RLC sublayer is 0, the MAC sublayer predicts the subsequent uplink data amount to be sent based on the "one-to-one" service type, so as to generate the BSR according to the non-zero value for reporting. By the scheme, under the condition of smaller uplink data interval, RB scheduling of the network equipment can be maintained, frequent triggering of random access is avoided, and data transmission efficiency of the user equipment is improved.

Fig. 6 shows a timing diagram of a buffer status report BSR reporting method corresponding to a service type with a data interaction mode of "single uplink mode". By way of example, such traffic types may be periodic heartbeat detection of an application, etc. As shown in fig. 6, the buffer status report BSR reporting method in this case may include:

in step 301, the MAC sublayer of the ue receives uplink data periodically sent by the APP layer.

In step 302, the MAC sublayer of the ue determines that the first uplink data amount to be transmitted in the PDCP sublayer and the RLC sublayer is 0.

In step 303, the MAC sublayer of the user equipment reports a BSR of non-zero value to the network equipment to maintain RB scheduling.

Step 304, the MAC sublayer of the ue receives the uplink data periodically sent by the APP layer again.

In step 305, the MAC sublayer of the user equipment sends uplink data to the network equipment.

In the above scheme, for the service type of "single uplink mode", because the APP layer of the ue periodically transmits uplink data, when detecting that the first uplink data amount buffered in the PDCP sublayer and the RLC sublayer is 0, the MAC sublayer may generate a BSR according to a non-zero value for reporting. By the scheme, RB scheduling of the network equipment can be maintained, when uplink data periodically transmitted by the APP layer is received again, triggering of random access can be avoided, and data transmission efficiency of the user equipment is improved.

Fig. 7 is a flowchart of another method for reporting a buffer status report BSR according to an embodiment of the present invention.

It should be noted that, to continuously acquire RB scheduling of the network device, the MAC sublayer needs to continuously report a BSR with a non-zero value to the network device before receiving uplink data again. If the MAC sublayer does not receive new uplink data for a long time, continuously acquiring RB scheduling of the network device may cause waste of air interface resources.

Based on the above description, the embodiment of the present invention may further set a maximum duration of reporting the BSR.

As shown in fig. 7, after reporting the BSR with a non-zero value to the network device, the method for reporting the buffer status report BSR provided by the embodiment of the present invention may further include:

in step 401, the MAC sublayer of the ue counts the reporting time of the BSR.

Step 402, after determining that the reporting time length of the BSR exceeds the preset maximum duration, the MAC sublayer of the user equipment reports a BSR with zero value to the network equipment.

By the technical scheme, the MAC sub-layer of the user equipment can timely send the zero value BSR to the network equipment when new uplink data is not received for a long time, so that the network equipment can stop scheduling the RB, on one hand, air interface resources can be saved, and on the other hand, the electric quantity of the user equipment can be saved.

Fig. 8 is a schematic structural diagram of a BSR reporting device according to an embodiment of the present invention. The buffer status report BSR reporting device in the embodiment of the present invention may be used as a buffer status report BSR reporting apparatus to implement the buffer status report BSR reporting method provided in the embodiment of the present invention.

And the reporting module 83 is configured to generate a BSR according to the second uplink data amount and report the BSR to the network device when the first uplink data amount is determined to be zero.

The second uplink data amount is a non-zero value obtained by predicting the uplink data amount to be sent in a preset time period by the determining module 82 according to the current service type; alternatively, the second amount of upstream data is a non-zero value preset in the determination module 82.

In a specific implementation manner, the obtaining module 81 is specifically configured to send a data amount query request to the PDCP sublayer and the RLC sublayer, respectively; receiving data volume information sent by the PDCP sub-layer and the RLC sub-layer according to the data volume inquiry request; and determining the PDCP sublayer and the first uplink data quantity to be transmitted in the RLC sublayer according to the data quantity information.

In a specific implementation manner, the determining module 82 is specifically configured to receive service indication information automatically sent by an application layer of the user equipment when the service is established; or, sending a service inquiry request to an application layer of the user equipment; and receiving service indication information sent by an application layer according to the service query request.

In a specific implementation manner, when the first uplink data amount is determined to be not zero, the reporting module 83 is further configured to generate a BSR according to the first uplink data amount and report the BSR to the network device.

In the embodiment of the present invention, the acquiring module 81 may acquire the PDCP sublayer and the first uplink data amount to be transmitted in the RLC sublayer after detecting that the BSR trigger condition is satisfied. If the first uplink data amount is zero, the reporting module 83 may generate a BSR according to the second uplink data amount and report the BSR to the network device. The second uplink data amount is a non-zero value obtained by predicting the uplink data amount to be sent in a preset time period by the determining module 82 according to the current service type; alternatively, the second amount of upstream data is a predetermined non-zero value. By the scheme, under the condition that the uplink data transmission interval is relatively short, the continuous RB scheduling of the network equipment can be acquired, and the frequent triggering of the random access process due to lack of the RB is avoided, so that the data transmission performance of the user equipment is improved.
