Resource scheduling method and device based on HSDPA (high speed downlink packet access)

Abstract

The invention discloses a resource scheduling method and device based on HSDPA (high speed downlink packet access). The method disclosed by the invention comprises the following steps: acquiring the signal channel quality parameters, scheduled times, accumulative throughput and QoS (quality of service) grade of each user to be scheduled; determining the scheduling priority of each user to be scheduled according to the acquired signal channel quality parameters, scheduled times, accumulative throughput and QoS grade of the user to be scheduled respectively; and selecting scheduled users and carrying out resource allocation for the selected scheduled users according to the scheduling priority of each user to be scheduled. By adopting the resource scheduling method and device based on HSDPA disclosed by the invention, when resources are scheduled, on the premises of considering the throughput and the equity of users, the requirement of ensuring the QoS of different service types can be realized.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to an HSDPA-based resource scheduling method and device thereof. Background technique [0002] In order to improve the download rate of TD (time division) network (such as TD-SCDMA time division-synchronous code division multiple access wireless access network), R5 introduces HSDPA (High Speed ​​Downlink Packet Access, high speed downlink packet access) technology, single carrier can Achieve a peak rate of 2.8Mbps. TD-SCDMAHSDPA system involves five channels, namely: [0003] HS-PDSCH: High-Speed ​​Physical Downlink Shared Channel, high-speed physical downlink shared channel, is an HSDPA service channel, used to carry high-level data of each UE (user equipment); [0004] HS-SICH: High-Speed ​​Shared Information Channel for HS-DSCH high-speed downlink shared channel shared information channel, is the HSDPA uplink control channel, used to carry and HS-DSCH (high-speed d...

AI Technical Summary

Problems solved by technology

However, since the user's fairness is mainly determined by the user's current cumulative throughput, this algorithm can only guarantee long-term fairness (that is, in a long period of time, the average rate of each user is basically the same) , but it cannot guarantee user fairness in a relatively short period of time, especially when users request services with high latency requirements, the existing resource scheduling methods cannot meet the service needs of these users

[0019] To sum up, the existing resource scheduling methods cannot meet the needs of users for services with different delay requirements while taking into account throughput and user fairness.
