Problems solved by technology

Although the conditions for determining the correct DCI are relaxed compared to US2018/0035411A1, the obtained RNTI and DCI may still be incorrect (e.g., under low signal-to-noise ratio (SNR) condit...

Embodiment Construction

[0024] image 3 An exemplary embodiment of an Unknown Site Identification Information (USII) decoder showing the inventive concept. In the illustrated embodiment, the terminal equipment (TE) 300 includes a communication device, such as a mobile phone device, UE, network node, network sniffer, vehicle-to-everything (V2X) unit, etc., which operates in a wireless network, such as a cellular wireless network (such as 4G cellular network system). TE300 is shown to include a number of functional blocks for performing its various functions. For example, the TE 300 of the illustrated embodiment includes a receiver 310 for providing received signal processing and providing the received signal and / or information extracted therefrom to a terminal functional block 320, which may include, for example, various data slots, control elements, user interface etc. Although the receiver 310 of the TE 300 is described as providing receive signal processing, it should be understood that the fun...

Abstract

Systems and methods are provided for accurately decoding received channel signals when station identification information is unknown. Embodiments accurately decode a Physical Downlink Control Channel(PDCCH) in order to obtain Downlink Control Information (DCI) without the need to know Radio Network Temporary Identity (RNTI) information. Embodiments of Unknown Site Identification Information (USII) use error reduction based redundancy checking (data decoded from candidate control channel data blocks containing redundant data and a portion of said candidate control channel data from data including redundancy reduction) An error check is performed between the decoded data in the block), and decoding is implemented when the station identification information is unknown. Embodiments of the USII decoder may use power detection techniques to identify candidate control channel data blocks for error checking operations based on redundancy reduction.

Description

【Technical field】 [0001] The present invention relates generally to wireless communications, and in particular to decoding channel signals such as the Physical Downlink Control Channel (PDCCH) using power detection and error checking based on redundancy reduction without labeling site identification information such as wireless network temporary identification (RNTI) information). 【Background technique】 [0002] Today's society relies extensively on data communications for a variety of purposes, such as messaging between individuals, broadcast communications, controlling machines, networking of processor-based systems, and the like. Data can be transmitted over a variety of channels, including wired, wireless, and optical, and is subject to various sources of noise, interference, and / or other signal degradation. For example, in cellular radio systems, radio transmissions are used to communicate bits of information between a base station (BS) and a handset and / or other user ...
