Blind decoding, or blind detection, is an operation foreseen by the 3GPP LTE/LTE-Advanced standards to allow the user equipment (UE) to gather control information related to the downlink shared channel. … The scheme used in LTE relies on the concatenation of a cyclic redundancy check (CRC) with a convolutional code.
What is blind search in LTE?
Blind Decoding Using DCI Search
The UE is only informed of the number of OFDM symbols within the control region of a subframe and is not provided with the location of its corresponding PDCCH. The UE finds its PDCCH by monitoring a set of PDCCH candidates in every subframe. This is referred to as blind decoding.
What is CCE in LTE?
Control Channel Element. The E-UTRA CCE is a group of resources which can be used to send a PDCCH (Physical Downlink Control Channel). One, two, four or eight CCEs can be grouped to support larger messages. Each CCE consists of 9 REGs (Resource Element Group).
What is paging message in LTE?
Paging in LTE network is used to inform and notify UE about various events. The propose of paging procedure is: … To inform UEs in RRC_IDLE and UEs in RRC_CONNECTED state about a system information change. To inform UE about ETWS primary notification and ETWS secondary notification.
What is DCI format in LTE?
DCI stands for Downlink Control Information. There are various DCI formats used in LTE in PDCCH. The DCI format is nothing but a predefined format in which the downlink control information is packed/formed and transmitted in PDCCH.
What is PRB utilization in LTE?
A E-UTRA PRB (Physical Resource Block) is defined as consisting of 12 consecutive subcarriers for one slot (0.5 ms). A PRB is the smallest element of resource allocation assigned by the eNB scheduler.
