Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] figure 1 A schematic diagram of a random access process triggered by false alarm information provided by an embodiment of the present invention, the method includes:

[0021] S11: The user equipment performs data transmission with the base station.

[0022] S12: The user equipment detects false alarm information, and parses to obtain random access related information. During the blind detection process, the UE may detect a PDCCH command that is not is...

Abstract

The embodiment of the invention discloses a false alarm information detection method and user equipment, which belongs to the technical field of communications. The method comprises the following steps: obtaining 1A-format physical downlink control channel commands; and judging whether the setup of bit information in the 1A-format physical downlink control channel commands meets preset conditionsor not, if not, determining the 1A-format physical downlink control channel commands as false alarm information, or judging whether lead code serial numbers indicated by the 1 A-format physical downlink control channel commands belong to the preset lead code serial number set or not, if the lead code serial number is not zero and does not belong to the preset lead code serial number set, determining the 1A-format physical downlink control channel commands as false alarm information. With the technical scheme, the false alarm information can be identified, and the abnormal flow triggered by the false alarm information can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for detecting false alarm information and user equipment. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) system, there are random access triggered by various conditions, such as initial random access, random access during handover, and random access triggered by MAC (Media Access Control, media access control). In addition, random access triggered by PDCCH (Physical Downlink Control Channel, physical downlink control channel) Order (command), etc., also exists random access caused by false alarm information. In the process of data transmission, since the UE uses a blind detection algorithm when demodulating and decoding the PDCCH channel, the UE cannot guarantee that the demodulated information is delivered by the eNB (eNodeB, evolved base station), so the solution cannot be guaranteed. The transferred information is c...
