Reference alerts comparable to -specific reference sign (PSS), main synchronization sign (PSS) / secondary synchronization sign (SSS), ItagPro and management channels similar to physical downlink control channel (PDCCH) and bodily broadcast channel (PBCH) are outlined. One of these provider known as an extension service or a new service sort (NCT). An object of the current invention is to provide a channel measuring methodology and a system using the same in a wireless communication system. Another object of the present invention is to supply a way for iTagPro smart tracker preventing a collision of a reference sign and an apparatus utilizing the same. RF (radio freqeuncy) unit for transmitting and receiving a radio signal and a processor connected to the RF unit. RRC layer of the first cell. FIG. 2 exhibits an example of a useful resource grid for one downlink slot. 3 shows a structure of a downlink subframe. FIG. Four is an exemplary diagram illustrating monitoring of a physical downlink management channel (PDCCH). FIG. 5 exhibits an example wherein a reference signal and a management channel are organized in a downlink subframe of 3GPP LTE.



FIG. 7 reveals an example of a bodily useful resource block (PRB) pair. FIG. 10 exhibits an example of a subframe construction of a single provider system and a provider aggregation system. FIG. 11 shows an instance of a subframe construction of a 3GPP LTE-A (advanced) system that's cross-provider scheduled by a carrier indicator discipline. FIG. 13 illustrates a channel measuring technique in a wireless communication system in keeping with an embodiment of the current invention. FIG. 14 is a block diagram illustrating a wireless communication system in which an embodiment of the present invention is implemented. CDMA may be applied by a radio know-how corresponding to universal terrestrial radio entry (UTRA) or iTagPro device CDMA2000. TDMA may be implemented with wireless technologies similar to global system for cellular communications (GSM) / general packet radio service (GPRS) / enhanced data rates for GSM evolution (EDGE). OFDMA may be implemented by wireless technologies akin to Institute of Electrical and Electronics Engineers (IEEE) 802.Eleven (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802-20, evolved UTRA (E-UTRA), ItagPro and the like.



UTRA is part of a common cell telecommunications system (UMTS). Third era partnership undertaking (3GPP) long term evolution (LTE) is a part of advanced UMTS (E-UMTS) using evolved-UMTS terrestrial radio entry (E-UTRA), itagpro device which employs OFDMA in downlink and SC in uplink -FDMA is adopted. LTE-A (superior) is the evolution of 3GPP LTE. It could also be referred to as other terms comparable to digital assistant, iTagPro device wireless modem, handheld gadget. NodeB (eNB), a base transceiver system (BTS), an access level (AP), and itagpro device the like. LTE includes LTE and / or iTagPro device LTE-A. 1 exhibits a radio body construction in 3GPP LTE. One subframe contains two consecutive slots. TTI may be referred to as a scheduling unit for information transmission. One slot features a plurality of orthogonal frequency division multiplexing (OFDM) symbols within the time area and a plurality of subcarriers within the frequency domain. OFDM symbol is used to signify one image period since 3GPP LTE uses OFDMA in downlink, and may be called a distinct title based on a a number of entry scheme.



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