Embodiment Construction

[0051] The basic technical idea of ​​the present invention is to use the multipath information of the uplink UE in the WCDMA system to correct the traditional load estimation method, and overcome the problem of relatively large errors caused by multipath mutual interference in current UE load estimation.

[0052] The method of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0053] Such as figure 2 Shown is the flowchart of the method of the present invention. Compared with the traditional method, the method of the present invention takes into account the multipath interference information of the UE when estimating the load, and mainly includes the following steps:

[0054] The first step is to use the improved SIR estimation algorithm to calculate the signal-to-interference ratio SIR of the UE k .

[0055] The second step is to calculate the multipath interference factor α of the kth UE k . ...

Abstract

The invention discloses a method for estimating the riser load of user equipment. The method comprises the steps as follows: calculating signal interference ratio of a computer user equipment; calculating multi path interference factor of user equipment; confirming load of user equipment basing on the multi path interference factor and the signal interference ratio. The invention utilizes the multi path information of an uplink user equipment on a WCDMA system in order to correct the traditional load estimation algorithm, thus eliminating the interference affect of the multi pathes. Load on the computer user equipment can be precisely worked out. Load estimating precision of the user equipment is improved as well as scheduled performance of an uplink HSUPA.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a processing technology of user services in a wireless communication system, in particular to a method for estimating uplink load of a UE (User Equipment, user equipment) in a CDMA (Code Division Multiple Access) system. Background technique [0002] The WCDMA (Wideband Code Division Multiple Access) system is a broadband cellular wireless communication system based on CDMA. The WCDMA system can support more types of services and higher data rate service transmission capabilities. HSUPA (High Speed ​​Uplink Packet Access, High Speed ​​Uplink Packet Access) technology is a technology for enhancing the uplink transmission capability of the WCDMA system. HSUPA technology includes shorter TTI (Transmission Time Interval, transmission time interval), NodeB (base station) based scheduler, HARQ (Hybrid Automatic Retransmission request, hybrid automatic retransmission request) and E-...
