A method for allocating frequency band resources

Abstract

The invention discloses a band resource allocation method. The method comprises the steps that if a terminal to be scheduled in a cell is a newly added terminal and a continuous available band resource which matches the terminal need and is not reserved exists, the resource is allocated to the terminal, otherwise a continuous band resource which meets a reservation condition is reserved for the terminal; if the terminal to be scheduled in the cell is a terminal with the reserved continuous band resource and a continuous available band resource which matches the terminal need exists, the resource is allocated to the terminal and a reservation state is removed; and if the continuous available band resource is not enough, whether the terminal seizes the reserved resource is determined according to the waiting time of the terminal. According to the band resource allocation method provided by the invention, cell band resource debris can be reduced; the band resource utilization is improved; the manners of allocation for the available band resource, reservation for unavailable resource and overtime seizing are used; businesses are reduced; and the waiting time of multiple get resources can be acquired.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a frequency band resource allocation method in a cellular wireless communication system. Background technique [0002] In the cellular wireless communication system, the scheduling algorithm is the core algorithm of the system radio resource management. The base station reasonably allocates cell resources to meet the requirements of ensuring service QoS (Quality of Service, quality of service), improving system throughput, and taking user fairness into account. For services with fixed time packet intervals and relatively fixed data packet sizes, some special services that need to ensure resource allocation, and systems with relatively limited resources, in order to reduce signaling overhead and scheduling delay, a semi-static transmission method is generally used, that is, Allocate resources for a period of time or periodical resources to users for service transmission.

AI Technical Summary

Problems solved by technology

However, in a semi-static transmission system, when single-band services randomly select resources, resulting in resource discretization, it is difficult to obtain continuous idle resources, and services with multi-band requirements cannot be satisfied for a long time, affecting user experience. In the case of insufficient single-frequency band services, multiple discrete non-continuous idle frequency bands cannot be utilized, resulting in waste of resources
