Reference alerts similar to -specific reference signal (PSS), primary synchronization sign (PSS) / secondary synchronization signal (SSS), and management channels reminiscent of physical downlink management channel (PDCCH) and bodily broadcast channel (PBCH) are defined. Such a carrier is named an extension carrier or a brand new provider type (NCT). An object of the present invention is to supply a channel measuring method and a machine utilizing the identical in a wireless communication system. Another object of the current invention is to supply a technique for iTagPro online preventing a collision of a reference signal and iTagPro reviews an apparatus using the same. RF (radio freqeuncy) unit for transmitting and receiving a radio signal and a processor related to the RF unit. RRC layer of the first cell. FIG. 2 shows an instance of a resource grid for one downlink slot. 3 reveals a structure of a downlink subframe. FIG. 4 is an exemplary diagram illustrating monitoring of a bodily downlink management channel (PDCCH). FIG. 5 reveals an instance during which a reference sign and a management channel are arranged in a downlink subframe of 3GPP LTE.

FIG. 7 exhibits an instance of a physical resource block (PRB) pair. FIG. 10 shows an example of a subframe construction of a single service system and iTagPro reviews a provider aggregation system. FIG. 11 shows an instance of a subframe structure of a 3GPP LTE-A (advanced) system that's cross-service scheduled by means of a provider indicator iTagPro reviews field. FIG. 13 illustrates a channel measuring technique in a wireless communication system in accordance with an embodiment of the present invention. FIG. 14 is a block diagram illustrating a wireless communication system through which an embodiment of the current invention is implemented. CDMA could also be carried out by a radio know-how resembling common terrestrial radio access (UTRA) or CDMA2000. TDMA may be applied with wireless applied sciences similar to global system for mobile communications (GSM) / general packet radio service (GPRS) / enhanced information charges for GSM evolution (EDGE). OFDMA may be implemented by wireless applied sciences akin to Institute of Electrical and Electronics Engineers (IEEE) 802.Eleven (Wi-Fi), IEEE 802.16 (WiMAX), itagpro tracker IEEE 802-20, advanced UTRA (E-UTRA), and the like.

UTRA is a part of a common mobile telecommunications system (UMTS). 3rd era partnership undertaking (3GPP) long term evolution (LTE) is part of developed UMTS (E-UMTS) using advanced-UMTS terrestrial radio entry (E-UTRA), which employs OFDMA in downlink and iTagPro reviews SC in uplink -FDMA is adopted. LTE-A (advanced) is the evolution of 3GPP LTE. It could also be referred to as other terms akin to digital assistant, wireless modem, handheld device. NodeB (eNB), a base transceiver system (BTS), an entry level (AP), and iTagPro bluetooth tracker the like. LTE consists of LTE and / or LTE-A. 1 exhibits a radio frame construction in 3GPP LTE. One subframe consists of two consecutive slots. TTI could also be known as a scheduling unit for data transmission. One slot features a plurality of orthogonal frequency division multiplexing (OFDM) symbols in the time area and a plurality of subcarriers in the frequency area. OFDM image is used to represent one symbol interval since 3GPP LTE uses OFDMA in downlink, and could also be known as a distinct name in response to a a number of entry scheme.

SC-FDMA when SC-FDMA is used as an uplink multiple entry scheme, iTagPro reviews the OFDM image may be referred to as an SC-FDMA image. FIG. 1 is merely an instance. Accordingly, the number of subframes included in the radio body, ItagPro the number of slots included in the subframe, or iTagPro reviews the number of OFDM symbols included in the slot may be variously modified. 3GPP LTE defines that one slot includes 7 OFDM symbols in a traditional cyclic prefix (CP), and one slot contains 6 OFDM symbols in an prolonged CP. FIG. 2 reveals an example of a resource grid for ItagPro one downlink slot. OFDM symbols in the time area and consists of N RB RBs within the frequency domain. N RB of resource blocks included within the downlink slot depends on a downlink transmission bandwidth set in a cell. One RB includes a plurality of subcarriers in the frequency area. Each component on the useful resource grid known as a resource ingredient (RE).
