Resource transmission method and wireless network subsystem

Abstract

The invention discloses a resource transmission method and a wireless network subsystem. The method comprises the following steps that: in a time-division synchronous code division multiple access uplink enhancement system, firstly, RNC sends an Iub oral signaling to a node B; the Iub oral signaling carries QoS parameters of uplink service; and after the node B receives the Iub oral signaling, the node B carries out resource allocation on user equipment UE in a scheduling authorization mode according to the obtained QoS parameters. With the resource transmission method and the wireless network subsystem, the RNC no longer allocates non-scheduling resource; and the node B enhances an absolute authorization channel to carry out the resource authorization on the UE.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a resource transmission method and a wireless network subsystem for a TD-SCDMA uplink enhanced system. Background technique [0002] In order to meet users' increasing demand for high-speed uplink packet data services, and to better cooperate with HSDPA (High-Speed ​​Downlink Packet Access) technology to provide support for higher service quality, 3GPP (3rd Generation Partnership Project, third Generation Cooperation Project) introduced HSUPA (High Speed ​​Uplink Packet Access) based on WCDMA (Wideband Code Division Multiple Access) and TD-SCDMA (Time Division Synchronous Code Division Multiple Access) in Rel6 (version 6) and Rel7 (version 7) respectively technology. HSUPA adopts technologies such as HARQ (Hybrid Automatic Repeat Request), 16QAM (Higher Order Modulation), and Node B (Node B) fast scheduling, which can obtain higher user peak rate and cell data throughput. ...

Problems solved by technology

However, for unscheduled transmissions, some problems are faced

First of all, since resources are allocated by RNC for users in a dedicated manner, no matter whether the business transmission is continuous or intermittent, and the QoS (Quality of Service) requirements of the business are high or low, once allocated, they must be occupied in a dedicated way, so the resources may not be fully utilized , there are problems of resource waste and low utilization; secondly, the RNC cannot understand the scheduling resource usage at the bottom of the system well, and this static allocation cannot reflect the most reasonable utilization of resources, which may reduce the overall performance of the system; thirdly, The method based on RNC high-level control will inevitably bring a relatively large delay. When initially establishing or reconfiguring non-scheduled transmission, the time delay will be relatively large, and at the same time, the air interface traffic will be increased.
