Problems solved by technology

[0004] The existing technology needs to traverse various pairing combinations, and the number of calculations is large. When the number of user equipment in the system is large, this method will lead to excessive delay, which may cause the scheduling to lag behind the state change of the user equipment, and affect the scheduling performance.

Embodiment Construction

[0021] The embodiment of the present invention determines whether the user equipment (UE) is located in the central area or the edge area, and if it is in the central area, resources are allocated independently for it; if it is in the edge area, a paired UE is selected for it, and resources are independently allocated for the paired UE. Since the UE in the central area does not participate in the comparison when selecting the paired UE, the number of calculations is reduced, and the scheduling performance is improved while implementing resource scheduling through space division multiplexing. Generally, it can ensure that the delay of the scheduling algorithm is limited to the user range of state changes.

[0022] see figure 1 , the main method flow of resource scheduling in this embodiment is as follows:

[0023] Step 101: Determine whether the user equipment is located in the central area or the edge area.

[0024] Step 102: When there is a user equipment located in the bor...

Abstract

The invention discloses a method for scheduling resources, which is used for obtaining resource scheduling through a space division multiplexing method and improving scheduling performance. The method includes that whether user equipment is located in a central area or a margin area is determined; when the user equipment is located in the margin area, user equipment is selected from margin-area user equipment which belongs to a different radio remote unit (RRU) from the user equipment in the margin area to be paired with the user equipment in the margin area; identical resources are allocated for the paired user equipment; and when the user equipment is located in the central area, resources are allocated for the user equipment in the central area independently. The invention further discloses a device for achieving the method.

Description

technical field [0001] The present invention relates to the communication field, in particular to a resource scheduling method and device. Background technique [0002] In order to improve the coverage performance, a distributed base station has been adopted, which includes a base band unit (BBU) and a remote radio unit (RRU). The BBU is the part responsible for data processing in the base station, and determines the data sent on each RRU. RRU is the radio frequency transmitting part of the base station. Each independent space corresponds to one RRU. One RRU can support data transmission of one or more channels, and each channel can be connected to one or more antennas. Multi-floor (equivalent to multiple independent spaces) joint scheduling mainly involves the user equipment pairing problem of space division multiplexing (SDMA). [0003] The resource scheduling process in the prior art includes: taking the user equipment with the highest scheduling priority as the primary...
