[0097] The example embodiments will now be described in detail with reference to the drawings. When the description is made with reference to the drawings, the same numbers on different drawings represent the same or similar elements. The following example embodiments described in the detailed description section are examples in which all features described do not necessarily have to be implemented. Conversely, not all of the features described in the claims have to be implemented. These features are merely examples and they do not limit the scope of the application as claimed.

[0098] At present, the building structure of a city is complex, and there can be many refractions and reflections, which increase the link loss of a terminal, so that the terminal needs to transmit greater power, resulting in excessive power consumption of the terminal.

[0099] When the terminal runs a game application, it needs to quickly and frequently receive user instructions, causing the terminal to frequently reconnect with the base station. Since the reconnection process takes a certain amount of time, it will affect the response delay of the application during running.

[0100] When the terminal runs a video application, if the terminal frequently receives instructions to switch to the next video, it needs to frequently reconnect with the base station. Since the reconnection process takes a certain amount of time, it will also affect the response delay of the application during running.

[0101] When the terminal runs a remote control application, it also needs to quickly and frequently receive user instructions. Based on the above description, it can be determined that it will also affect the response delay of the application during running.

[0102] The above is only an example, and other types of applications may also be affected by frequent reconnection with the base station, affecting the response delay during running.

[0103] In addition, in the related art, the resource scheduling process between the terminal and the base station can refer to Figure 1A as shown, including the following steps:

[0104] Step 1, when the terminal determines that there is data to be sent, it reports an SR (Scheduling Request) message to the base station. The terminal can send the SR message to the base station through the PUCCH (Physical Uplink Control Channel).

[0105] Step 2, after the base station receives the SR message, it evaluates according to the resource reservation situation and issues uplink authorization information to the terminal.

[0106] The base station can carry DCI (Downlink Control Information) through the PDCCH (Physical Downlink Control Channel), and the DCI includes the uplink authorization information for scheduling uplink resources for the terminal. At this time, the base station will schedule a small number of resource blocks to the terminal.

[0107] Step 3, the terminal reports data and / or buffer status report to the base station, and the base station sends new uplink authorization information to the terminal (not shown in Figure 1A ) according to the indication of the buffer status report and the resource reservation situation of the base station, in order to adjust the uplink resources of the terminal.

[0108] The terminal can send data and / or a buffer status report (BSR) to the base station through a physical uplink shared channel (PUSCH).

[0109] In step 4, the base station sends indication information to the terminal to indicate whether the data needs to be retransmitted according to the decoding result of the received terminal data.

[0110] In the prior art, the base station is a 4G base station. Figure 1A The base station can send indication information including an ACK (acknowledge) character to the terminal in the case of successful decoding, and the terminal determines that the data does not need to be retransmitted according to the indication information. The base station can also send indication information including a NACK (non-acknowledge) character to the terminal in the case of unsuccessful decoding, and the terminal determines that the data needs to be retransmitted according to the indication information.

[0111] In step 5, when the terminal determines that there is no data to be sent, the terminal sends a BSR to the base station to indicate that the amount of data to be sent is 0, and the base station stops scheduling resources for the terminal.

[0112] In addition, if the base station is a 5G base station, the implementation process of resource scheduling is similar to the above process, but the indication information sent by the base station in step 4 is no longer an ACK character or a NACK character, but an NDI (new data indicator), as shown in Figure 1B The terminal can determine whether the data needs to be retransmitted to the base station according to whether the NDI sent by the base station is reversed.

[0113] The NDI reversal can refer to the value of the NDI changing from 0 last time to 1 this time, or from 1 to 0. If the NDI is reversed, the terminal determines that the data has been successfully decoded by the base station and does not need to be retransmitted. If the NDI is not reversed, the terminal needs to retransmit the last data to the base station.

[0114] It can be seen that in the related art, once the terminal determines that there is no data to be sent, the base station stops scheduling resources for the terminal. If the terminal has data to be sent again, the terminal still requests the base station to schedule resources through an SR message, which causes the terminal to frequently send SR messages to the base station, resulting in large power consumption of the terminal and large response delay of an application program running on the terminal.

[0115] To address the aforementioned technical issues and balance the response latency of applications on the terminal during operation with the terminal's power consumption, this disclosure provides the following resource scheduling method. The resource scheduling method provided in this disclosure will first be introduced from the perspective of the base station.

[0116] Reference Figure 2 As shown, Figure 2 This is a flowchart illustrating a resource scheduling method according to an exemplary embodiment of this disclosure, described from the perspective of the base station. Figure 2 As shown, the resource scheduling method includes the following steps:

[0117] In step 201, the first buffer status report is received from the receiving terminal.

[0118] In this embodiment of the disclosure, the first cache status report can be used to indicate that the terminal has no data to be sent. Specifically, the first cache status report can indicate that the amount of data to be sent on the terminal is currently 0.

[0119] In step 202, in response to determining that the target parameter value used to indicate channel quality is greater than the corresponding preset threshold, first uplink grant information is sent to the terminal.

[0120] In this embodiment of the disclosure, the target parameter value may include, but is not limited to, at least one of the following: CQI (Channel Quality Indication) value; PHR (Power Headroom) value; RSRP (Reference Signal Receiving Power) value. The first uplink grant information is used to indicate the resources of the first resource block scheduled by the base station for the terminal, and the number of the first resource blocks is less than a preset number.

[0121] In one possible implementation, the base station may send the first scheduling information to the terminal if any one of the CQI value, PHR value, and RSRP value is greater than the corresponding preset threshold.

[0122] In another possible implementation, the base station may send the first scheduling information to the terminal if any two of the CQI, PHR, and RSRP values ​​are greater than the corresponding preset thresholds.

[0123] In another possible implementation, the base station may also send the first scheduling information to the terminal when the CQI value, PHR value, and RSRP value are all greater than the corresponding preset thresholds.

[0124] The base station can send the first uplink grant information to the terminal through DCI, thereby scheduling a PUSCH (Physical Uplink Share Channel) resource for the terminal, that is, scheduling the resources of the first resource block. In the embodiment of the present disclosure, the base station can schedule a small amount of resources of the first resource block for the terminal.

[0125] In the above embodiment, the base station can schedule a small amount of resources of the first resource block for the terminal in an area with good signal coverage in the case where it is determined that the terminal has no data to be sent, thereby avoiding the terminal power consumption caused by frequent connection reconstruction between the terminal and the base station, improving the terminal endurance time, and reducing the response time delay of the application program on the terminal in the running process.

[0126] In some optional embodiments, referring to Figure 3 , the method further includes the following steps: Figure 3 , the method further includes the following steps: Figure 2 is a flowchart of another resource scheduling method according to the embodiment shown in

[0127] In step 203, when it is determined that the target parameter value is greater than the corresponding preset threshold value, a timer with a target duration is started.

[0128] The target duration is used to indicate the duration of the resources of the first resource block having uplink authorization. The target duration can be determined by the base station or pre-agreed by the protocol, and the present disclosure does not limit this.

[0129] Correspondingly, step 202 can specifically include:

[0130] Before the timer ends, the first uplink grant information is continuously sent to the terminal.

[0131] In the embodiment of the present disclosure, the base station will continuously send the first uplink grant information to the terminal according to the specified period before the timer ends, thereby continuously scheduling the resources of the first resource block for the terminal.

[0132] In the above embodiment, the base station can start the timer in an area with good channel quality, and continuously schedule the resources of the first resource block for the terminal before the timer ends, thereby achieving the purpose of starting resource pre-scheduling for the terminal in an area with good channel quality. If the terminal generates new data, it can directly send it to the base station through the first resource block without sending a scheduling request message to the base station, thereby avoiding the terminal power consumption caused by frequent connection reconstruction between the terminal and the base station, improving the terminal endurance time, and reducing the response time delay of the application program on the terminal in the running process.

[0133] In some optional embodiments, referring to Figure 4As shown, Figure 4 is a flowchart of another resource scheduling method according to the embodiment shown in Figure 2 As shown in the flowchart of another resource scheduling method according to the embodiment shown in

[0134] In step 204, the first data sent by the terminal through the first resource block is received.

[0135] The first data is data generated after the terminal reports the first buffer status report. In the embodiment of the present disclosure, the terminal sends the first data to the base station through the first resource block within the target time duration when the resource of the first resource block has uplink authorization, and the base station directly receives it.

[0136] In the above embodiment, the base station can receive the first data sent by the terminal through the pre-scheduled first resource block, so that the terminal does not need to initiate resource scheduling through the scheduling request message again, avoids the terminal power consumption caused by frequent initiation of resource scheduling request, improves the terminal endurance time, and reduces the response time delay of the application program on the terminal in the running process.

[0137] In some optional embodiments, referring to Figure 5 As shown, Figure 5 is a flowchart of another resource scheduling method according to the embodiment shown in Figure 2 As shown in the flowchart of another resource scheduling method according to the embodiment shown in

[0138] In step 205, the second buffer status report reported by the terminal through the first resource block is received.

[0139] In the embodiment of the present disclosure, the terminal can report the second buffer status report through the first resource block within the target time duration.

[0140] In step 206, second uplink authorization information is sent to the terminal based on the second buffer status report.

[0141] The second uplink authorization information is used to indicate the resources of the second resource block scheduled by the base station for the terminal. After receiving the second buffer status report, the base station can schedule the resources of the second resource block for the terminal according to the data amount of the second data indicated by the second buffer status report and the resource reservation condition of the base station itself, and send the second uplink authorization information to the terminal.

[0142] In step 207, the second data sent by the terminal through the second resource block is received.

[0143] In the above embodiment, the base station can receive the second buffer status report reported by the terminal through the first resource block, and then send second uplink grant information to the terminal, so that the terminal sends second data to the base station through the second resource block scheduled by the second uplink grant information, which is simple and convenient to use.

[0144] In some optional embodiments, referring to Figure 6 , the method can further include the following steps: Figure 6 , the method can further include the following steps: Figure 2 , the method can further include the following steps:

[0145] In step 208, in response to determining that the target parameter value is less than the corresponding preset threshold value, the resource scheduling for the terminal is stopped.

[0146] In the embodiments of the present disclosure, the target parameter value includes at least one of the following: CQI value; PHR value; RSRP value.

[0147] In one possible implementation, the base station can send first scheduling information to the terminal when any one of the CQI value, the PHR value, and the RSRP value is greater than the corresponding preset threshold value, and stop the resource scheduling for the terminal when all of the CQI value, the PHR value, and the RSRP value are less than the corresponding preset threshold value.

[0148] In another possible implementation, the base station can send first scheduling information to the terminal when any two of the CQI value, the PHR value, and the RSRP value are greater than the corresponding preset threshold value, and stop the resource scheduling for the terminal when two or more of the CQI value, the PHR value, and the RSRP value are less than the corresponding preset threshold value.

[0149] In another possible implementation, the base station can send first scheduling information to the terminal when all of the CQI value, the PHR value, and the RSRP value are greater than the corresponding preset threshold value, and stop the resource scheduling for the terminal when any one of the CQI value, the PHR value, and the RSRP value is less than the corresponding preset threshold value.

[0150] The above is only an example, and the base station can flexibly determine whether to continue the resource scheduling for the terminal according to the channel quality.

[0151] In the above embodiment, the base station can stop the resource scheduling for the terminal in the area with poor signal coverage when it is determined that the terminal has no data to be sent, that is, the pre-scheduling function of the pre-scheduled first resource block is turned off, thereby achieving the purpose of saving the terminal energy consumption.

[0152] Next, the resource scheduling method provided by the present disclosure is introduced from the terminal side.

[0153] Referring to Figure 7 as shown, Figure 7 is a flowchart of a resource scheduling method according to an example embodiment of the present disclosure, which is described from the terminal side. The terminal includes but is not limited to a mobile phone, a notebook computer, a desktop computer, an iPad, etc. As shown in Figure 7 , the resource scheduling method includes the following steps:

[0154] In step 301, a first buffer status report is reported to the base station in response to determining that there is no data to be sent.

[0155] In the embodiment of the present disclosure, the first buffer status report can be used to indicate that the terminal has no data to be sent. Specifically, the first buffer status report can indicate that the amount of data currently to be sent on the terminal is 0.

[0156] In step 302, the first uplink grant information sent by the base station when the target parameter value for indicating the channel quality is greater than the corresponding preset threshold value is received.

[0157] The target parameter value includes but is not limited to at least one of the following: a channel quality indicator (CQI) value; a power headroom (PHR) value; a reference signal received power (RSRP) value. The first uplink grant information is used to indicate the first resource block of resources scheduled by the base station for the terminal, and the number of the first resource block is less than a preset number.

[0158] In the above embodiment, even if the terminal has no data to be sent, the base station can pre-schedule a small amount of resources of the first resource block for the terminal in an area with good signal coverage. At this time, the power loss of the terminal is small, the transmission power is low, and the energy consumption of the terminal is not too large. The terminal can stay on the 4G or 5G network, avoiding the terminal power consumption caused by the terminal frequently sending a scheduling request message to the base station using multi-antenna diversity, improving the terminal endurance time, and reducing the response time delay of the application program on the terminal during operation.

[0159] In some optional embodiments, referring to Figure 8 as shown, Figure 8 is a flowchart of another resource scheduling method according to the embodiment shown in Figure 7 , after step 302 is performed, the method can further include the following steps:

[0160] In step 303, in response to generating first data, the first data is sent to the base station through the first resource block.

[0161] The terminal reports the first data to the base station through the first resource block within the target duration of the uplink grant of the first resource block.

[0162] In the above embodiment, the terminal can send the first data to the base station through the first resource block pre-scheduled by the base station, avoid the terminal energy consumption caused by frequent initiation of the scheduling request message, and reduce the response delay of the application in the running process.

[0163] In some optional embodiments, referring to Figure 9 , the method further includes the following steps after step 302: Figure 9 is a flow chart of another resource scheduling method according to the embodiment shown in Figure 7 , the method further includes the following steps after step 302:

[0164] In step 304, the second buffer status report is reported to the base station through the first resource block.

[0165] The second buffer status report is used to indicate the data amount of the second data to be sent by the terminal. In the embodiment of the present disclosure, when the terminal determines that the trigger condition for reporting the second buffer status report is met within the target time length, the second buffer status report is reported to the base station through the first resource block.

[0166] In one possible implementation, the terminal can determine that the trigger condition is met when the time point for periodically reporting the buffer status report is reached.

[0167] In another possible implementation, the terminal determines that the trigger condition is met when it is determined that the second data needs to be sent to the base station.

[0168] Of course, the terminal can also determine that the trigger condition is met under other conditions, which is not limited in the present disclosure.

[0169] In step 305, the second uplink authorization information sent by the base station based on the second buffer status report is received.

[0170] The second uplink authorization information is used to indicate the resources of the second resource block scheduled by the base station for the terminal.

[0171] In step 306, the second data is sent to the base station through the second resource block.

[0172] In the above embodiment, the terminal can report the second buffer status report to the base station through the first resource block, so that the base station re-schedules the uplink of the terminal, and the terminal sends the second data to the base station based on the second resource block scheduled by the second uplink authorization information, thereby avoiding the terminal energy consumption caused by frequent initiation of the scheduling request message, and reducing the response delay of the application in the running process.

[0173] In the embodiments of the present disclosure, in the process that the terminal reports the first data based on the first resource block, the terminal can determine that the data transmitted by the terminal last time does not need to be retransmitted according to the indication information including the ACK character transmitted by the base station, or the terminal can determine that the data transmitted by the terminal last time needs to be retransmitted through the first resource block when receiving the indication information including the NACK character transmitted by the base station.

[0174] Of course, the terminal can also determine whether the data transmitted last time needs to be retransmitted according to whether the NDI transmitted by the base station is reversed.

[0175] The resource scheduling method of the present disclosure is further illustrated as follows.

[0176] Referring to Figure 10A Figure 10A is a flowchart of another resource scheduling method according to an embodiment, which can include the following steps:

[0177] In step 401, when the terminal determines that there is data to be transmitted, the terminal reports an SR message to the base station.

[0178] In step 402, after the base station receives the SR message, the base station evaluates according to the resource reservation condition, and sends an uplink grant information to the terminal.

[0179] The base station can carry the DCI through the PDCCH, and the DCI includes the uplink grant information for scheduling the uplink resource for the terminal. At this time, the base station will schedule a small amount of resource blocks to the terminal.

[0180] In step 403, the terminal reports the data and / or the buffer status report to the base station, and the base station sends a new uplink grant information to the terminal according to the indication of the buffer status report and the resource reservation condition of the base station, so as to adjust the uplink resource of the terminal.

[0181] In step 404, the base station sends the indication information for indicating whether the data needs to be retransmitted to the terminal according to the decoding condition of the received terminal data.

[0182] The base station is a 4G base station, which can send the indication information including the ACK character to the terminal in the case of successful decoding, and the terminal determines that the data does not need to be retransmitted according to the indication information. The base station can also send the indication information including the NACK character to the terminal in the case of unsuccessful decoding, and the terminal determines that the data needs to be retransmitted according to the indication information.

[0183] In step 405, the terminal reports a first buffer status report to the base station in response to determining that there is no data to be transmitted.

[0184] ​In step 406, the base station starts a timer with a target duration in response to determining that the target parameter value indicating the channel quality is greater than the corresponding preset threshold, and continuously sends the first uplink grant information to the terminal before the timer ends.

[0185] The first uplink grant information is used to indicate the resources of the first resource block scheduled by the base station for the terminal, and the number of the first resource block is less than a preset number. The target duration is used to indicate the duration of the resources of the first resource block having uplink authorization.

[0186] Referring to Figure 10B As shown in the figure, in the case that the first buffer status report indicates that the amount of data currently to be sent on the terminal is 0, the base station will continue to schedule a small amount of resources of the first resource block for the terminal to send data.

[0187] In step 407, the terminal sends first data to the base station through the first resource block.

[0188] The first data is the data newly generated after the terminal reports the first buffer status report.

[0189] In step 408, the terminal sends a second buffer status report to the base station through the first resource block.

[0190] In step 409, the base station sends second uplink grant information to the terminal based on the second buffer status report.

[0191] In step 410, the terminal sends second data to the base station through the second resource block.

[0192] Optionally, the terminal can send a third buffer status report to the base station through the second resource block, wherein the third buffer status report is used to indicate the amount of data of the data currently buffered by the terminal to be sent.

[0193] In the above embodiment, even if the terminal has no data to be sent, the base station can pre-schedule a small amount of resources of the first resource block for the terminal in an area with good signal coverage. At this time, the power loss of the terminal is small, the transmission power is low, and the energy consumption of the terminal is not too large. The terminal can stay on the 4G or 5G network, avoiding the terminal power consumption caused by the terminal frequently sending scheduling request messages to the base station using multi-antenna diversity, improving the terminal endurance time, and reducing the response time delay of the application program on the terminal in the running process.

[0194] Of course, the above steps 406 to 410 can also be replaced by steps 406'(not shown in step 406'): Figure 10A

[0195] ​At step 406', the base station stops resource scheduling for the terminal in response to determining that the target parameter value for indicating the channel quality is less than the corresponding preset threshold.

[0196] In the above embodiment, the base station can turn off the pre-scheduling function in the area with poor channel quality and stop resource scheduling for the terminal in the case of determining that the terminal has no data to be sent, thereby achieving the purpose of reducing terminal power consumption and prolonging terminal endurance time. The application program running on the terminal is balanced in terms of response delay and terminal power consumption by automatically turning on or off the scheduling function by the base station.
