Sub-frame load balancing method and system in time division duplex system

Abstract

The invention provides a sub-frame load balancing method and system in a time division duplex system, and belongs to the field of wireless communication. The method comprises the following steps: S1)determining the number of continuous same-direction subframes according to a frame structure type; S2) numbering the continuous same-direction sub-frames in sequence and setting a resource allocationthreshold value for each sub-frame; S3) sequentially allocating resources to be scheduled according to the subframe numbers and the threshold values corresponding to the subframes, obtaining allocatedresource values of the current scheduling subframes after the resources are allocated each time, and if the allocated resource values of the current scheduling subframes exceed the resource allocation threshold values corresponding to the subframes, going to the step S4); otherwise, judging whether the to-be-allocated resources are remained or not; if yes, setting a resource allocation thresholdvalue for the next to-be-scheduled subframe again, and executing the step S3) again, otherwise, turning to the step S4), and S4) ending the resource allocation, thereby realizing the load balancing control between the continuous same-direction subframes in the TDD system, and avoiding the problem that the equipment is easy to damage due to sudden load change between the subframes.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a load balancing method among subframes in a time division duplex system and a load balancing system between subframes in a time division duplex system. Background technique [0002] The fifth generation of mobile communication technology (The 5th Generation, hereinafter referred to as 5G) was born to meet the new requirements for cellular mobile communication systems in recent years, such as extreme speed, ultra-low latency, ultra-high reliability, and support for massive connections. 5G requires Penetrating into all fields of future social life, forming a user-centered all-round information ecosystem, which can provide users with fiber-like access speed, "zero" delay experience, and can also support hundreds of billions of devices Various application scenarios, such as ultra-high connection capability, ultra-high traffic density, ultra-high connection density, and ultra-hi...

Problems solved by technology

However, in TDD mode, due to the staggered appearance of uplink and downlink subframes, the fixed mapping relationship between the subframes that send scheduling signaling and the subframes that transmit data may cause some individual subframes to be heavily loaded, while some The load on the subframe is very light, and sudden changes in the load will accelerate hardware damage
