OFDM Symbol Number in A Slot

Reference signals equivalent to -specific reference sign (PSS), primary synchronization signal (PSS) / secondary synchronization sign (SSS), iTagPro product and management channels corresponding to bodily downlink management channel (PDCCH) and physical broadcast channel (PBCH) are defined. Such a service is named an extension provider or a brand iTagPro product new provider kind (NCT). An object of the current invention is to supply a channel measuring methodology and a device using the identical in a wireless communication system. Another object of the current invention is to offer a way for preventing a collision of a reference sign and an apparatus utilizing the identical. RF (radio freqeuncy) unit for transmitting and iTagPro product receiving a radio sign and iTagPro technology a processor connected to the RF unit. RRC layer of the first cell. FIG. 2 shows an example of a useful resource grid for bluetooth keychain tracker one downlink slot. 3 shows a construction of a downlink subframe. FIG. Four is an exemplary diagram illustrating monitoring of a bodily downlink control channel (PDCCH). FIG. 5 shows an example wherein a reference signal and a control channel are organized in a downlink subframe of 3GPP LTE.

FIG. 7 shows an example of a physical resource block (PRB) pair. FIG. 10 shows an example of a subframe construction of a single service system and ItagPro a carrier aggregation system. FIG. Eleven shows an example of a subframe construction of a 3GPP LTE-A (advanced) system that's cross-service scheduled through a carrier indicator area. FIG. Thirteen illustrates a channel measuring method in a wireless communication system in response to an embodiment of the current invention. FIG. 14 is a block diagram illustrating a wireless communication system through which an embodiment of the current invention is carried out. CDMA could also be implemented by a radio expertise comparable to universal terrestrial radio entry (UTRA) or CDMA2000. TDMA may be implemented with wireless applied sciences corresponding to international system for mobile communications (GSM) / common packet radio service (GPRS) / enhanced information rates for GSM evolution (EDGE). OFDMA may be carried out by wireless applied sciences corresponding to Institute of Electrical and ItagPro Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802-20, best bluetooth tracker evolved UTRA (E-UTRA), and the like.

UTRA is part of a common cellular telecommunications system (UMTS). Third technology partnership undertaking (3GPP) long term evolution (LTE) is part of advanced UMTS (E-UMTS) utilizing advanced-UMTS terrestrial radio access (E-UTRA), 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 different phrases akin to digital assistant, wireless modem, handheld system. NodeB (eNB), a base transceiver system (BTS), an entry point (AP), and the like. LTE consists of LTE and iTagPro product / or LTE-A. 1 exhibits a radio frame structure in 3GPP LTE. One subframe contains two consecutive slots. TTI may be known as a scheduling unit for knowledge transmission. One slot features a plurality of orthogonal frequency division multiplexing (OFDM) symbols within the time domain and a plurality of subcarriers in the frequency area. OFDM image is used to signify one image period since 3GPP LTE makes use of OFDMA in downlink, and iTagPro product could also be called a distinct name in keeping with a multiple entry scheme.

SC-FDMA when SC-FDMA is used as an uplink multiple access scheme, the OFDM image could also be referred to as an SC-FDMA image. FIG. 1 is merely an instance. Accordingly, the variety of subframes included within the radio body, the variety of slots included within the subframe, iTagPro product or the number of OFDM symbols included within the slot could also be variously modified. 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 prolonged CP. FIG. 2 reveals an instance of a resource grid for one downlink slot. OFDM symbols in the time area and contains N RB RBs in the frequency area. N RB of resource blocks included within the downlink slot is determined by a downlink transmission bandwidth set in a cell. One RB includes a plurality of subcarriers in the frequency domain. Each component on the useful resource grid is named a useful resource ingredient (RE).
