Problems solved by technology

[0003] The existing technology is usually based on the link simulation, combined with the measured decoding ability, to select a fixed initial start decoding time, but due to the changeable wireless channel environment, the position where the decoding is successfully completed is often not fixed
The FET scheme is implemented by fixing the initial decoding time, and the decoding will be started frequently until it succeeds. Frequent decoding will inevitably lead to an increase in power consumption and system load. The increase in power consumption will affect the effect of the FET characteristics itself; the load is large Increase, will affect the task scheduling and timing requirements of the system as a whole

Abstract

The embodiment of the invention discloses a method and device for determining a decoding moment. The method comprises the following steps: acquiring a time slot for initial decoding starting in each TTI in at least one transmission time interval TTI, wherein the at least one TTI comprises the first TTI, the first TTI is the last TTI in the at least one TTI; determining a first time slot for initial decoding starting in a second TTI according to the time slot for initial decoding starting and a preset reference time domain, wherein the second TTI is the next TTI of the first TTI. The method and device for determining the decoding moment provided by the embodiment of the invention are capable of determining the moment for initial decoding starting in the next TTI according to the initial decoding moment in the latest or more TTI, thereby avoiding the repeated decoding, and effectively reducing the power consumption and system load expenditure caused by frequent decoding.

Description

technical field [0001] The present invention relates to the field of communication, and more specifically, to a method and device for determining the decoding moment. Background technique [0002] Frame Early Termination (English full name: Frame Early Termination, abbreviation: FET) technology is a wireless air interface new technology of wideband code division multiple access mobile communication system (English full name: Wideband Code Division Multiple Access, abbreviation: WCDMA). The reception and transmission of the uplink and downlink Dedicated Physical Control Channel (English full name: Dedicated Physical Control Channel, abbreviation: DPCCH) / Dedicated Physical Data Channel (Dedicated Physical DataChannel, abbreviation: DPDCH) can end the wireless frame in advance, so as to achieve a similar " Dedicated channel (English full name: Dedicated Channel, abbreviated: DCH) discontinuous transmission (English full name: DiscontinuousTransmission, abbreviated: DTX) / disco...
