Reference signals resembling -particular reference sign (PSS), primary synchronization signal (PSS) / secondary synchronization sign (SSS), and management channels equivalent to physical downlink control channel (PDCCH) and bodily broadcast channel (PBCH) are defined. One of these provider is named an extension carrier or a new provider type (NCT). An object of the current invention is to supply a channel measuring method and iTagPro bluetooth tracker a machine using the identical in a wireless communication system. Another object of the current invention is to offer a method for stopping a collision of a reference sign and an apparatus using 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 primary cell. FIG. 2 exhibits an example of a resource grid for one downlink slot. Three 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 through which a reference signal and a control channel are arranged in a downlink subframe of 3GPP LTE.
FIG. 7 exhibits an example of a physical useful resource block (PRB) pair. FIG. 10 exhibits an example of a subframe structure of a single carrier system and a carrier aggregation system. FIG. 11 shows an example of a subframe construction of a 3GPP LTE-A (superior) system that is cross-provider scheduled by means of a service indicator area. FIG. 13 illustrates a channel measuring methodology 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 by which an embodiment of the current invention is implemented. CDMA may be applied by a radio expertise comparable to universal terrestrial radio entry (UTRA) or CDMA2000. TDMA could also be carried out with wireless applied sciences corresponding to global system for buy itagpro cellular communications (GSM) / general packet radio service (GPRS) / enhanced knowledge rates for buy itagpro GSM evolution (EDGE). OFDMA could also be applied by wireless applied sciences akin to Institute of Electrical and Electronics Engineers (IEEE) 802.Eleven (Wi-Fi), buy itagpro IEEE 802.16 (WiMAX), iTagPro shop IEEE 802-20, evolved UTRA (E-UTRA), and the like.
UTRA is a part of a common mobile telecommunications system (UMTS). 3rd technology partnership venture (3GPP) long run evolution (LTE) is part of developed UMTS (E-UMTS) utilizing advanced-UMTS terrestrial radio entry (E-UTRA), which employs OFDMA in downlink and SC in uplink -FDMA is adopted. LTE-A (superior) is the evolution of 3GPP LTE. It may be referred to as different phrases resembling digital assistant, wireless modem, handheld gadget. NodeB (eNB), a base transceiver system (BTS), an access level (AP), and the like. LTE includes LTE and / or LTE-A. 1 shows a radio frame structure in 3GPP LTE. One subframe contains two consecutive slots. TTI could also be known as a scheduling unit for information transmission. One slot includes a plurality of orthogonal frequency division multiplexing (OFDM) symbols within the time area and a plurality of subcarriers in the frequency area. OFDM image is used to represent one image interval since 3GPP LTE makes use of OFDMA in downlink, and buy itagpro may be called a distinct title in response to a multiple entry scheme.
SC-FDMA when SC-FDMA is used as an uplink a number of entry scheme, the OFDM symbol may be known as an SC-FDMA symbol. FIG. 1 is merely an instance. Accordingly, the number of subframes included in the radio body, buy itagpro the number of slots included within the subframe, or the number of OFDM symbols included in the slot could also be variously changed. 3GPP LTE defines that one slot contains 7 OFDM symbols in a traditional cyclic prefix (CP), and one slot contains 6 OFDM symbols in an extended CP. FIG. 2 shows an example of a resource grid for one downlink slot. OFDM symbols in the time domain and includes N RB RBs within the frequency area. N RB of resource blocks included in the downlink slot relies on a downlink transmission bandwidth set in a cell. One RB features a plurality of subcarriers within the frequency domain. Each ingredient on the useful resource grid is called a useful resource ingredient (RE).
