Embodiment Construction

[0139] 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 creative efforts fall within the protection scope of the present invention.

[0140] In the prior art, the UE blindly detects information without knowing the channel environment in which it is located. In fact, the channel environment where the UE is located is different. If the UE is in a good channel environment, a part of the detection information can be self-decodable, or a part of the self-decodable DCI or SIB (maybe Multiple transmissions, under a good channel environment, only need to detect a few times) can meet the detection require...

Abstract

Embodiments of the present invention provide an information detection method and user equipment, which relate to the communication field and enable the user equipment to reduce detection delay, power consumption and detection complexity without knowing the channel environment where it is located. The method is as follows: first determine the reference information, then determine the detection level of at least one target information in the main information block, downlink control information, and system information block according to the reference information, and then perform the detection level of the target information according to the detection level of the target information. detection to obtain the target information. Embodiments of the present invention are used for detection of information.

Description

technical field [0001] The present invention relates to the communication field, in particular to an information detection method and user equipment. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) system, the user equipment (User Equipment, UE) first monitors the primary synchronization signal (Primary Synchronization Signal, PSS) and the secondary synchronization signal (Secondary Synchronization Signal, SSS) after starting up, and obtains a rough frequency Synchronization, cell identification, frame timing and other information, and then detect the Physical Broadcast Channel (Physical Broadcast Channel, PBCH), and obtain the main information block (Master Information Block, MIB) carried by the PBCH. The UE monitors the Physical Downlink Control Channel (PDCCH) according to the obtained MIB, and uses the System Information-Radio Network Temporary Identifier (SI-RNTI) to perform Cyclic Redundancy Check (Cyclic Redundancy) on the PDCCH. C...
