Problems solved by technology

[0009] However, according to the latest 3GPP protocol, the upper layer message will no longer pre-set the target thermal noise. Specifically, the radio network controller (RNC) only configures the target total power according to the current total power reported by the NodeB and sends the target total power For NodeB, that is, the upper layer message only presets the target total power for NodeB, which makes it impossible for NodeB to calculate the target uplink load factor
Obviously, the prior art cell load scheduling method is no longer applicable to the current situation

Embodiment Construction

[0031] The core idea of ​​the present invention is: only preset the target total power RTWP according to the upper layer message T arg et With this feature, cell load scheduling is performed based on total power.

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the following examples are given and the present invention is further described in detail with reference to the accompanying drawings.

[0033] The principle of the cell load scheduling method of the present invention is: NodeB compares the current total power RTWP of the cell with the target total power RTWP of the cell T arg et , according to the comparison result, it is determined whether the UE in the cell should be scheduled at present, and the goal of the scheduling is to make the scheduled total power approach the target total power, wherein the target total power is pre-configured.

Abstract

This invention discloses a small area load dispatching method used in the local area load dispatch to one or more than one high speed up-packet data access HSUPA UE from a base station including: A, Node B determines if the dispatch is needed currently based on the measured RTWP and RTWPTarget, if so, step B is carried out, otherwise, this flow is ended, B, Node B determines the anticipated HSUPAUE should be dispatched in said local area by dispatch computation, C, Node B dispatches the anticipated HSUPA UE based on the designed dispatch algorithm, which can dispatch loads of local area according to the received bandwidth total power only accurately.

Description

technical field [0001] The present invention relates to a cell load scheduling method, in particular to a cell load scheduling method for high-speed uplink packet data access (HSUPA) user equipment (UE). Background technique [0002] In order to improve the transmission rate of the uplink in the 3G communication system, in order to better support multimedia services and packet data transmission, 3GPP organization introduced HSUPA technology in the R6 protocol. HSUPA adopts key technologies such as base station NodeB fast uplink scheduling, hybrid automatic repeat request (HARQ) protocol, and 2ms short frame, which greatly improves the uplink throughput of HSUPA UE and the uplink capacity of the communication system. Among them, the uplink The theoretical maximum peak rate reached 5.76Mbps, realizing the purpose of increasing the uplink transmission rate. [0003] figure 1 is the protocol structure diagram of HSUPA, such as figure 1 As shown, in terms of the protocol frame...
