specific Embodiment 1

[0054] The application scenario of this embodiment is that the terminal receives the FPACH channel, and the overall process is as follows figure 2 shown.

[0055] 1. According to the high-level instructions, the UE detects the FPACH channel in real time at the known location until the cyclic redundancy check is correct;

[0056] 2. The UE parses the information carried by the FAPCH channel, and judges the validity of the target monitoring channel according to the parsed information;

[0057] If the UE judges that there is at least one of the following conditions in the information carried by the FPACH channel, perform step 3, otherwise perform step 4;

[0058] (1), the signal reference number in the information carried by the FPACH channel is inconsistent with the signal reference number sent by the UE in the UpPCH;

[0059] (2), the relative subframe number in the information carried by the FPACH channel is not equal to the difference between the subframe number in which t...

Abstract

The invention discloses a monitoring type channel receiving method. The method is characterized in that UE (unified equipment) detects monitoring type channels at a determination position in real time according to an upper-layer instruction until the CRC (cyclic redundancy check) is correct; the UE analyzes the information carried by the target monitoring type channels, and judges the validity of the target monitoring type channels are valid according to the analyzed information; and if the target monitoring type channels are valid, and the UE carries out the follow-up operations according to the information carried by the target monitoring type channels, otherwise, the UE continues to detect the monitoring type channels in real time. The UE judges the validity of the detected information in accordance with the contents of the information carried by the monitoring channels after the UE detects the monitoring channels with the valid CRC verification, thus the false alarm rate of the monitoring type channels is effectively reduced, and the validity of receiving the monitoring type channels by the UE is improved, thereby improving the accuracy ratio of the UE follow-up operations.

Description

technical field [0001] The present invention relates to mobile communication system monitor channel sending and receiving technology, in particular to a time division-synchronous code division multiple access (abbreviation, TD-SCDMA) system mobile terminal receiving monitor class channel method. Background technique [0002] With the deepening of the commercialization of high-speed packet access applications, the application support of high-speed packet access (referred to as HSPA) has become a must for user terminals. ) system is the core competitive advantage of the existing second-generation mobile communication (abbreviation, 2G) network. [0003] In HSPA, there is such a type of monitoring channel. A mobile terminal (UE for short) can only know the location of its physical resource, but cannot know whether it exists or not. It needs to monitor it according to the criteria clearly specified in the corresponding standard. This type of monitoring channel is based on the s...
