Problems solved by technology

[0005] Since the power offset range of E-DPCCH and E-DPDCH channels is much larger than that of DPDCH, and the channel model of HSUPA is relatively different from that of R99, this threshold is no longer accurate, especially in handover In some scenarios, the rate of HSUPA may decrease

Embodiment Construction

[0019] A specific implementation method of a method and device for setting a multipath threshold in the present invention will be described below with reference to the accompanying drawings and specific implementation manners.

[0020] In an embodiment of the present invention, a method for setting a multipath threshold is as follows figure 1 shown, including the following steps:

[0021] Step s101, acquiring the power offset of the channel and the value of the detected multipath energy.

[0022] Specifically, the power offset can be the power offset of channels such as DPDCH, E-DPDCH, and E-DPCCH to the DPCCH channel, and the detected multipath energy is the value of the DPCCH channel energy, which can be the most detected The energy value of the strong path (the path with the highest energy) may also be the sum of the detected multipath energy or the average value of the detected multipath energy and the like.

[0023] Step s102, fitting the power offset of the channel and...

Abstract

The embodiment of the invention discloses a method for setting a multipath threshold. The method comprises the following steps: obtaining power bias and the detected multipath energy value of a channel; and fitting the power bias and the multipath energy of the channel to obtain the relation between the power bias and the multipath energy, thereby obtaining the multipath threshold under the power bias. The embodiment of the invention discloses a device for setting the multipath threshold. Through the embodiment, the method adopts dynamic setting of the multipath threshold according to the dynamic bias, increases the probability of accurately detecting multipath and is favorable for improving performance, in particular the performance under high speed uplink packet access.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for setting a multipath threshold. Background technique [0002] When a UE (User Equipment, user equipment) initiates access and conducts a call, the base station side establishes a dedicated channel for the UE. In order to maintain real-time tracking of the UE, the NodeB (base station) will detect the captured UE's path position and path energy frame by frame, and perform DPDCH (Dedicated Physical Data Channel, dedicated physical data channel) according to the detected multipath position. Demodulation of E-DPCCH (E-DCHDedicated Physical Control Channel, E-DCH Dedicated Physical Control Channel) and E-DPDCH (E-DCH Dedicated Physical Data Channel, E-DCH Dedicated Physical Data Channel). When detecting the multipath position, it is necessary to compare the detected energy of each phase with a threshold to extract the multipath. This threshold is ...
