Problems solved by technology

The interference of users is not considered in the calculation of the priority. Therefore, the scheduling method in the prior art cannot guarantee the service rate, especially to improve the service efficiency of the UE located at the edge of the cell, and the invention can improve the spectral efficiency and throughput of the cell. Maximize user experience

Embodiment 1

[0069] Step 301: When the current system uses eICIC technology and the current subframe is an ABS, use the specified UE scheduled on the ABS and / or all UEs entering the coverage of the base station to establish a scheduling queue for the current subframe.

[0070] Step 302: Using the interference factor mapping rule, calculate the interference factor of each UE in the scheduling queue of the current subframe.

[0071] Assuming that a UE with an index of 10 is extracted from the scheduling queue of the current subframe, and the UE is designated to access the ABS, its BLER in the current subframe is obtained as 0.35, and the UE is obtained in The minimum BLER value of each schedulable subframe except the current subframe is 0.35, and the difference value is 0. According to the difference value, the corresponding interference factor is found from Table 1 to be FF Interference =64.

Embodiment 2

[0080] Step 401: When the current system uses eICIC technology and the current subframe is non-ABS, use all UEs that enter the coverage of the base station except those designated for ABS subframe scheduling as UEs that need to be scheduled to establish a scheduling queue for the current subframe.

[0081] Step 402: Calculate the interference factor of each UE in the scheduling queue of the current subframe by using the interference factor mapping rule.

[0082] Assuming that the current subframe is subframe 2, and the UE whose ID (Index) is 12 is extracted from the scheduling queue of the current subframe, its BLER in the current subframe is obtained = 0.55, and Other schedulable subframes outside the subframe, that is, the minimum BLER on subframes 0, 1, 3, 4, 5, 6, 7, 8, and 9 is 0.1, and the difference is 0.45. According to the The difference is found from Table 1 and the corresponding interference factor is FF Interference =1.

Embodiment 3

[0089] Step 501: The current system does not use the eICIC technology, and establishes a scheduling queue for the current subframe by taking all UEs that enter the coverage of the base station as UEs that need to be scheduled.

[0090] Step 502: Using the interference factor mapping rule, calculate the interference factor of each UE in the scheduling queue of the current subframe.

[0091] Assuming that the current subframe is subframe 0, and the UE whose ID (Index) is 5 is extracted from the scheduling queue of the current subframe, its BLER in the current subframe is obtained = 0.1, and the UE is Other schedulable subframes outside the subframe, that is, the minimum BLER on subframes 1, 2, 3, 4, 5, 6, 7, 8, and 9 is 0.05, and the difference is 0.05. According to the The difference is found from Table 1 and the corresponding interference factor is FF Interferenec =32.

[0092] Step 503: According to the priority factor calculation formula, use the interference factor of eac...

Abstract

The present invention discloses a resource scheduling method, comprising: calculating the interference factor of each user equipment (UE) in the scheduling queue of the current subframe by using the interference factor mapping rule; calculating the interference factor of the current subframe by using the interference factor of each UE The priority corresponding to each UE in the scheduling queue of the frame; allocate resources to the UE according to the priority corresponding to each UE in the scheduling queue of the current subframe. The present invention also discloses a device for resource scheduling. The present invention can reduce the impact of cell interference on UE scheduling, improve service efficiency, especially improve service efficiency of UE located at the edge of the cell, and improve the spectrum efficiency and throughput of the cell. Maximize user experience.

Description

technical field [0001] The present invention relates to scheduling technology in the field of mobile communication, in particular to a resource scheduling method and device. Background technique [0002] At present, the scheduling in the Long Term Evolution (LTE, Long Term Evolution) system includes: calculating the priority of each user equipment (UE, User Equipment) according to the scheduling algorithm; sorting each UE according to the priority of the UE, according to Priority order allocates resources for each UE. [0003] However, since the calculation of the priority in the above scheduling method mainly uses parameters such as the UE's channel quality, historical throughput rate, and service attribute. The interference of users is not considered in the calculation of the priority. Therefore, the scheduling method in the prior art cannot guarantee the service rate, especially to improve the service efficiency of the UE located at the edge of the cell, and the inventio...
