Abstract

A scheduling method and a base station. The method comprises: determining whether or not a cell is congested; when the determination result is such that the cell is congested, a base station ceases to request a pertaining base station controller for data of a first user equipment (UE), where the first UE is a UE having the cell as an auxiliary cell, and the base station is a base station that pertains to the cell. By applying embodiments of the present invention, when a cell is congested, a base station that pertains to the cell ceases to request a base station controller for transmission of data of a UE having the cell as an auxiliary cell. This reduces scheduling of the data of the UE via the base station and allows the data of the UE to be scheduled by another base station, thus increasing multipoint transmission efficiency of the UE.

Description

 Scheduling method and base station

Technical field

[01] The present invention relates to the field of communications technologies, and in particular, to a scheduling method and a base station. Background technique

[02] The 3rd Generation Partnership Project (3GPP) protocol introduced downlink multipoint transmission technology in Release 11 (Release 11, R11). In the communication system using downlink multipoint transmission technology, A user equipment (User Equipment, UE) can simultaneously establish downlink connections with the same-frequency cells of different base stations. When performing downlink transmission, the radio network controller (RNC) will offload data to different base stations, which are different. The base station sends to the UE. For example, the UE establishes a downlink connection with two co-frequency cells of the two base stations, where one cell is the primary serving cell of the UE (referred to as the primary cell), and the other cell is the secondary serving cell of the UE (referred to as the secondary cell), usually the primary The channel quality of the cell is better than the channel quality of the secondary cell. The channel quality can be represented by a channel quality indicator (CQI). The secondary cell and the primary cell simultaneously schedule the UE to transmit downlink data, which can improve system resource utilization. [03] It is assumed that for a certain cell, the UE that uses the cell as the secondary cell is the first UE of the cell, and the UE that uses the cell as the primary cell is the second UE, and the scheduling priority of the first UE is generally set to be absolutely low. The scheduling priority of the second UE ensures that the cell resource can be preferentially allocated for use by the second UE. However, the inventor found in the research of the prior art that for the UE to which the downlink multi-point transmission technology is applied, since the scheduling priority of the UE in its secondary cell is the lowest, when the secondary cell is congested, it is difficult to provide the transmission resource. Used by the UE to reduce the multi-point transmission efficiency of the UE. Summary of the invention

The above described objects, features, and advantages of the embodiments of the present invention will become more apparent and understood. The technical solution is described in further detail.

[68] Referring to FIG. 1, a flowchart of an embodiment of a scheduling method according to the present invention is provided: [69] Step 101: Determine whether a cell is congested.

In this embodiment, the UE may establish a downlink connection with the same-frequency cell of at least two base stations at the same time, and use the established downlink connection to apply downlink multi-point transmission technology for downlink data transmission. One of the at least two base stations is the primary base station of the primary cell of the UE, and the base station other than the primary base station is the secondary base station of the secondary secondary cell of the UE. The UE accessing the above-mentioned cell has a scheduling queue of data, and the base station of the cell performs downlink data transmission scheduling on the UE accessing the cell according to the priority order of the scheduling queue. It should be noted that, in the embodiment of the present invention, the UE that uses the cell as the primary cell may be a UE that supports the downlink multi-point transmission technology, or It is a UE that does not support downlink multipoint transmission technology.

[71] In this embodiment, it is assumed that the first UE is a UE that uses the cell as a secondary cell, the second UE is a UE that uses the cell as a primary cell, and the base station is a base station to which the cell belongs. When the base station determines whether the cell is congested, it may determine whether the scheduling number of the first UE in the preset time period is lower than the threshold number, and/or determine that the scheduling time of the scheduling queue of the at least one second UE is greater than the threshold time, where The second UE and the first UE belong to the same logical port on the cell, and the scheduling time is a time required to schedule the cached data in the scheduling queue of the at least one second UE by using the air interface sending rate of the at least one second UE.

[72] Step 102: When the judgment result is that the cell is congested, the base station does not request the first base station controller to which it belongs.

UE data. [73] For the different manners of determining whether the cell is congested in step 101, in this step, when the result of the determination is that the number of times of scheduling of the first UE in the preset time period is lower than the threshold number, the cell congestion is determined; or When the judgment result is that the scheduling time of the scheduling queue of the at least one second UE is greater than the threshold time, the cell congestion is determined.

[74] Further, although the base station does not request to send the data of the first UE to the base station controller, new data is not added in the scheduling queue of the first UE, but the first UE is still not scheduled in the scheduling queue. Therefore, the base station can improve the scheduling priority of the scheduling queue of the first UE in the cell, and schedule the first UE according to the increased scheduling priority. Specifically, the base station may set the scheduling priority of the scheduling queue of the first UE to be higher than the scheduling priority of the scheduling queues of other UEs whose cached data in the scheduling queue of the first UE belongs to the same service type, thereby making the first The UE is preferentially scheduled by the base station, so as to improve the downlink multi-point transmission efficiency of the first UE, or the base station may also set the scheduling queue of the first UE. The scheduling priority is the same as the scheduling priority of the scheduling queues of other UEs in the scheduling queue of the first UE that belong to the same service type, so that the base station can have the first priority of the scheduling queue according to the prior art. The UE performs the scheduling, because the scheduling priority of the scheduling queue of the first UE is improved, so that the opportunity for the first UE to be scheduled is also increased, thereby improving the downlink multi-point transmission efficiency of the first UE; or, the base station is also The scheduling priority of the scheduling queue of the first UE may be multiplied by a preset parameter to generate a scheduling priority of the new scheduling queue of the first UE, and the preset parameter If the scheduling priority of the scheduling queue of the first UE is increased, the new scheduling priority of the first UE is increased. Therefore, the scheduling of the first UE is also increased. Opportunity, thereby improving the downlink multipoint transmission efficiency of the first UE.

[75] Further, in the first optional implementation manner, when the first UE accesses the cell, the base station may advance The scheduling priority of the scheduling queue of the first UE is set to the default by default, so that the second UE can preferentially use the transmission resources of the cell for downlink data transmission. Correspondingly, when the cell is congested, it is difficult for the first UE to complete the downlink multi-point transmission through the cell. If the base station still requests the base station controller to send the data of the first UE, there will be more and more first UEs. It is difficult for the data to implement downlink scheduling transmission through the base station, and therefore the base station no longer requests the base station controller to transmit the data of the first UE. In a second optional implementation, when the first UE accesses the cell, the base station may also set the scheduling priority of the scheduling queue of the first UE to the scheduling priority of the scheduling queue of the second UE, This ensures that the first UE and the second UE have the same scheduling opportunity. Correspondingly, when the cell is congested, it indicates that the second UE has a large amount of data to be preferentially transmitted. If the base station still requests the base station controller to send the data of the first UE, it will cause the second UE to obtain sufficient transmission resources, so the base station does not The base station controller is then requested to send data of the first UE.

[76] It can be seen from the above embodiment that when the cell is congested, the base station to which the cell belongs stops requesting to send the data of the UE that uses the cell as the secondary cell to the base station controller, and reduces the data of the UE scheduled by the base station, so that the UE is enabled. The data can be scheduled by other base stations, thereby improving the multi-point transmission efficiency of the UE; and, since the remaining data in the scheduling queue of the UE can be scheduled by increasing the scheduling priority of the UE, the UE can be further improved. Multi-point transmission efficiency.

[77] Referring to FIG. 2, a flow chart of another embodiment of the scheduling method of the present invention is as follows:

[78] Step 201: When the first UE initially accesses the cell, the base station to which the cell belongs sets the scheduling priority of the scheduling queue of the first UE in the cell to be the lowest, and the first UE is supplemented by the cell. UE of the cell.

In this embodiment, the UE can establish a downlink connection with the same-frequency cells of at least two base stations at the same time, and use the established downlink connection to apply downlink multi-point transmission technology for downlink data transmission. Among the at least two base stations, one of the base stations is the primary base station of the primary cell of the UE, and the base station other than the primary base station is the secondary base station of the secondary secondary cell of the UE. The UE accessing the above-mentioned cell has a scheduling queue of data, and the base station of the cell performs downlink data transmission scheduling on the UE accessing the cell according to the priority order of the scheduling queue. It should be noted that, in the embodiment of the present invention, the UE that uses the cell as the primary cell may be a UE that supports the downlink multi-point transmission technology, or may be a UE that does not support the downlink multi-point transmission technology.

[00] In this embodiment, it is assumed that the first UE is a UE that uses the cell as a secondary cell, the second UE is a UE that is the primary cell of the cell, and the base station is a base station to which the cell belongs. When the first UE accesses the cell, the base station to which the cell belongs may preset that the scheduling priority of the scheduling queue of the first UE is the lowest in the cell, thereby ensuring that the second UE can preferentially use the transmission resource of the cell for downlink data transmission. . [202] Step 202: The base station determines whether the number of times of scheduling of the first UE in the preset time period is lower than a threshold number. If yes, step 203 is performed; otherwise, the current process ends.

[82] In this embodiment, the scheduling priority of the first UE in the cell is preset to be the lowest, the base station may determine whether the scheduling number of the first UE is lower than the threshold number within the preset time period, if lower than The number of thresholds indicates that the first UE is difficult to complete downlink multipoint transmission through the cell.

[83] It should be noted that, in this step, the base station may also determine that the scheduling time of the scheduling queue of the second UE is greater than the threshold time, and if yes, execute step 203; otherwise, end the current process. The second UE and the first UE belong to the same logical port on the cell, and the scheduling time is a time required to schedule the cached data in the scheduling queue of the at least one second UE by using the air interface sending rate of the at least one second UE. In this embodiment, the scheduling priority of the first UE is set to be the lowest, so the base station can determine whether the scheduling time of the scheduling queue of the at least one UE is greater than the threshold time. If the threshold time is greater than the threshold time, the second UE has a large amount of data. Priority scheduling, so it is difficult for the first UE to complete downlink multi-point transmission through the cell.

[84] Step 203: The base station does not request the data of the first UE from the base station controller.

[85] When the base station determines that the number of scheduling of the first UE in the preset time period is lower than the threshold number, if the base station still requests the base station controller to send the data of the first UE, there will be more and more first It is difficult for the data of the UE to implement downlink scheduling transmission through the base station, so the base station does not request the data of the first UE from the base station controller to which it belongs.

[86] Step 204: The base station increases the scheduling priority of the scheduling queue of the first UE in the cell.

[007] In step 203, the secondary base station does not request the data of the first UE from the base station controller, so that the new data of the first UE is not added to the scheduling queue of the first UE, but the scheduling queue still exists. The first UE is not scheduled data, so the base station can improve the scheduling priority of the scheduling queue of the first UE in the cell. Specifically, the base station may set the scheduling priority of the scheduling queue of the first UE to be higher than the scheduling priority of the scheduling queues of other UEs whose cached data in the scheduling queue of the first UE belongs to the same service type, thereby making the first The UE is preferentially scheduled by the base station to improve the downlink multi-point transmission efficiency of the first UE, or the base station may also set the scheduling queue of the first UE, as compared with the second UE that transmits the same service to the first UE. The scheduling priority is the same as the scheduling priority of the scheduling queues of other UEs in the scheduling queue of the first UE that belong to the same service type, so that the base station can have the first priority of the scheduling queue according to the prior art. The UE performs the scheduling, because the scheduling priority of the scheduling queue of the first UE is improved, so that the opportunity for the first UE to be scheduled is also increased, thereby improving the downlink multi-point transmission efficiency of the first UE; or, the base station is also The first UE can be The scheduling priority of the scheduling queue is multiplied by the preset parameter to generate a scheduling priority of the new scheduling queue of the first UE, and the preset parameter is greater than 1, so the generated new scheduling priority is lower than the original scheduling priority of the first UE. If the scheduling priority of the scheduling queue of the first UE is increased, the opportunity for scheduling the first UE is also increased, thereby improving the downlink multi-point transmission efficiency of the first UE. [88] Step 205: The base station schedules the first UE according to the adjusted scheduling priority, and ends the current process.

It can be seen from the foregoing embodiment that when the cell is congested, the base station to which the cell belongs stops requesting to send the data of the UE that uses the cell as the secondary cell to the base station controller, and reduces the data of the UE that is scheduled by the base station, so that the UE is enabled. The data can be scheduled by other base stations, thereby improving the multi-point transmission efficiency of the UE; and, since the remaining data in the scheduling queue of the UE can be scheduled by increasing the scheduling priority of the UE, the UE can be further improved. Multi-point transmission efficiency.

[90] Referring to FIG. 3, a flow chart of another embodiment of the scheduling method of the present invention is as follows:

[91] Step 301: When the first UE initially accesses the cell, the base station to which the cell belongs sets the scheduling priority of the scheduling queue of the first UE in the cell to be the lowest, and the first UE uses the cell as the secondary cell. UE.

In this embodiment, the UE can establish a downlink connection with the same-frequency cell of at least two base stations at the same time, and use the established downlink connection to apply downlink multi-point transmission technology for downlink data transmission. Among the at least two base stations, one of the base stations is the primary base station of the primary cell of the UE, and the base station other than the primary base station is the secondary base station of the secondary secondary cell of the UE. The UE accessing the above-mentioned cell has a scheduling queue of data, and the base station of the cell performs downlink data transmission scheduling on the UE accessing the cell according to the priority order of the scheduling queue. It should be noted that, in the embodiment of the present invention, the UE that uses the cell as the primary cell may be a UE that supports the downlink multi-point transmission technology, or may be a UE that does not support the downlink multi-point transmission technology.

In this embodiment, it is assumed that the first UE is a UE that uses the cell as a secondary cell, the second UE is a UE that uses the cell as a primary cell, and the base station is a base station to which the cell belongs. When the first UE accesses the cell, the base station to which the cell belongs may preset that the scheduling priority of the scheduling queue of the first UE is the lowest in the cell, thereby ensuring that the second UE can preferentially use the transmission resource of the cell for downlink data transmission. . [94] Step 302: The base station determines whether the number of times of scheduling of the first UE in the preset time period is lower than the threshold number. If yes, step 303 is performed; otherwise, the current process ends.

[95] Since the scheduling priority of the first UE in the cell is preset to be the lowest in this embodiment, the base station may And determining whether the number of times of scheduling of the first UE is lower than a threshold number in a preset time period. If the number of times of the first UE is lower than the threshold number, the first UE is difficult to complete downlink multi-point transmission through the cell.

[96] Step 303: The base station does not request the data of the first UE from the base station controller.

[97] When the base station determines that the number of scheduling of the first UE in the preset time period is lower than the threshold number, if the base station still requests the base station controller to send the data of the first UE, there will be more and more first It is difficult for the data of the UE to implement downlink scheduling transmission through the base station, so the base station does not request the data of the first UE from the base station controller to which it belongs.

[98] Step 304: The base station determines whether the queue length of the scheduling queue of the first UE is less than the set threshold length. If yes, step 305 is performed; otherwise, step 307 is performed.

[99] In step 303, the base station does not request the data of the first UE to the base station controller to which it belongs, so that no new data is added to the scheduling queue of the first UE, but the first UE still exists in the scheduling queue. Unscheduled data. In this embodiment, different operations may be performed according to the size of the unscheduled data amount in the scheduling queue.

[100] In this embodiment, when the base station determines whether the queue length of the scheduling queue of the first UE is less than the threshold length, the base station may use any one of the following methods: [101] In the first mode, the base station may determine the first UE. Whether the amount of the buffered data in the scheduling queue is smaller than the first threshold data amount, and if the amount of the data is smaller than the first threshold, the queue length of the scheduling queue of the first UE is less than the set threshold length;

[102] In the second mode, the base station may determine whether the ratio of the amount of the buffered data in the scheduling queue of the first UE to the first rate of the first UE is less than the second threshold duration, where the first rate is when the base station separately schedules the first UE. The rate is calculated by the average CQI reported by the first UE and the available power and code resources of the cell. The calculation process is consistent with the prior art, and is not described herein again; when the cached data in the scheduling queue of the first UE is used The ratio of the quantity to the first rate of the first UE is less than the second threshold duration, indicating that the queue length of the scheduling queue of the first UE is less than the set threshold length;

[103] In a third mode, the base station may determine whether the ratio of the amount of buffered data in the scheduling queue of the first UE to the second rate of the first UE is less than a third threshold duration, where the second rate is a preset historical time period of the base station. The maximum average rate of the first UE is scheduled internally, where the historical time period is a period of time before the current time of the first UE. For example, if the preset historical time period is I s (seconds), the first UE counts the first time every 100 ms (milliseconds) within the I s The average rate that the UE is scheduled, and then takes the largest average rate as the second rate; when the ratio of the buffered data volume in the scheduling queue of the first UE to the second rate of the first UE is less than the third threshold duration, It indicates that the queue length of the scheduling queue of the first UE is less than the set threshold length.

[104] Step 305: The base station increases the scheduling priority of the first UE in the scheduling queue of the secondary cell. [105] When the base station determines that the queue length of the scheduling queue of the first UE is less than the set threshold length, it indicates that only a small amount of data is not scheduled in the scheduling queue of the first UE, so that the first UE may be improved. The scheduling priority of the scheduling queue in the cell is used to schedule the data of the first UE. At this time, since the first UE has less data, the downlink multi-point transmission efficiency of the first UE is improved. The data transmission of the second UE is greatly affected. Specifically, the base station may set the scheduling priority of the scheduling queue of the first UE to be higher than the scheduling priority of the scheduling queues of other UEs that belong to the same service type in the scheduling queue of the first UE, so that the first The UE is preferentially scheduled by the base station, so as to improve the downlink multi-point transmission efficiency of the first UE, or the base station may also set the scheduling queue of the first UE. The scheduling priority is the same as the scheduling priority of the scheduling queues of other UEs in the scheduling queue of the first UE that belong to the same service type, so that the base station can have the first priority of the scheduling queue according to the prior art. The UE performs the scheduling, because the scheduling priority of the scheduling queue of the first UE is improved, so that the opportunity for the first UE to be scheduled is also increased, thereby improving the downlink multi-point transmission efficiency of the first UE; or, the base station is also The scheduling priority of the scheduling queue of the first UE may be multiplied by a preset parameter to generate a scheduling priority of the new scheduling queue of the first UE, and the preset parameter is preset. If the scheduling priority of the scheduling queue of the first UE is increased, the first scheduling priority of the first UE is also increased. Opportunity, thereby improving the downlink multipoint transmission efficiency of the first UE.

[106] Step 306: The base station schedules the first UE according to the adjusted scheduling priority, and ends the current process.

[107] Step 307: The base station sends a notification message to the base station controller, where the notification message is used to notify the base station controller to forward the buffered data in the scheduling queue of the first UE to the base station to which the primary cell of the first UE belongs to perform scheduling, and end Current process. [108] When the base station determines that the queue length in the scheduling queue of the first UE is not less than the set threshold length, it indicates that more data remaining in the scheduling queue of the first UE is not scheduled, if the first UE is still upgraded. Scheduling the priority will affect the data transmission of the second UE. Therefore, the base station sends a notification message to the base station controller, and notifies the base station controller to forward the buffered data in the scheduling queue of the first UE to the primary base station of the primary cell of the first UE for scheduling, without affecting the data transmission of the second UE. At the same time, it is ensured that the data of the first UE can be normally transmitted. [109] It can be seen from the above embodiment that when the cell is congested, the base station to which the cell belongs stops requesting to send the data of the UE that uses the cell as the secondary cell to the base station controller, and reduces the data of the UE that is scheduled by the base station, so that the UE is enabled. The data can be scheduled by other base stations, thereby improving the multi-point transmission efficiency of the UE; and, since the remaining data in the scheduling queue of the UE can be scheduled by increasing the scheduling priority of the UE, the UE can be further improved. Multi-point transmission efficiency.

[110] Referring to FIG. 4, a flow of another embodiment of the scheduling method of the present invention is as follows:

[111] Step 401: When the first UE initially accesses the cell, the base station to which the cell belongs sets the scheduling priority of the scheduling queue of the first UE in the cell to be consistent with the scheduling priority of the second UE, where the first UE For the UE with the cell as the secondary cell, the second UE is the UE with the cell as the primary cell. In this embodiment, the UE may establish a downlink connection with the same-frequency cell of at least two base stations at the same time, and use the established downlink connection to apply downlink multi-point transmission technology for downlink data transmission. Among the at least two base stations, one of the base stations is the primary base station of the primary cell of the UE, and the base station other than the primary base station is the secondary base station of the secondary secondary cell of the UE. The UE accessing the above-mentioned cell has a scheduling queue of data, and the base station of the cell performs downlink data transmission scheduling on the UE accessing the cell according to the priority order of the scheduling queue. It should be noted that, in the embodiment of the present invention, the UE that uses the cell as the primary cell may be a UE that supports the downlink multi-point transmission technology, or may be a UE that does not support the downlink multi-point transmission technology.

In this embodiment, when the first UE accesses the cell, the base station to which the cell belongs may set the scheduling priority of the scheduling queue of the first UE to the scheduling priority of the scheduling queue of the second UE. It is ensured that the first UE and the second UE have the same scheduling opportunity. [114] Step 402: The base station determines whether the scheduling time of the scheduling queue of the at least one second UE is greater than the threshold time. If yes, step 403 is performed; otherwise, step 404 is performed.

[115] In this step, the at least one second UE may be the same logical port as the first UE belongs to the cell.

The UE, the scheduling time is a time required to schedule the cached data in the scheduling queue of the at least one second UE at the air interface transmission rate of the at least one second UE. The base station may periodically determine whether the scheduling time of the scheduling queue of the at least one second UE is greater than the threshold time by using a preset time T as a period.

[116] Step 403: The base station does not request the data of the first UE from the base station controller.

[117] In this step, when the scheduling time of the scheduling queue of the at least one second UE is greater than the threshold time, If the at least one second UE has a large amount of data, it needs to transmit preferentially. If the base station still requests the base station controller to send the data of the first UE, it will cause the second UE to obtain sufficient transmission resources, so the base station does not request the base station controller. One UE data.

[118] Step 404: The base station schedules the first UE according to the scheduling priority of the first UE, and ends the current process. [119] When the base station does not request the data of the first UE from the base station controller, new data is not added to the scheduling queue of the first UE of the cell, and the base station follows the original scheduling priority of the first UE. A UE can perform scheduling.

[120] It can be seen from the above embodiment that when the cell is congested, the base station to which the cell belongs stops requesting to send the data of the UE that uses the cell as the secondary cell to the base station controller, and reduces the data of the UE that is scheduled by the base station, so that the UE is enabled. The data can be scheduled by other base stations, thereby improving the multi-point transmission efficiency of the UE.
