OFDM Symbol Number In A Slot
Reference indicators akin to -specific reference signal (PSS), major synchronization signal (PSS) / secondary synchronization sign (SSS), and management channels equivalent to bodily downlink control channel (PDCCH) and bodily broadcast channel (PBCH) are outlined. This type of provider is named an extension service or a new provider sort (NCT). An object of the current invention is to provide a channel measuring methodology and a machine using the identical in a wireless communication system. Another object of the current invention is to provide a way for stopping a collision of a reference sign and an apparatus using the same. RF (radio freqeuncy) unit for transmitting and receiving a radio sign and a processor linked to the RF unit. RRC layer of the primary cell. FIG. 2 shows an example of a useful resource grid for one downlink slot. Three exhibits a structure of a downlink subframe. FIG. Four is an exemplary diagram illustrating monitoring of a physical downlink control channel (PDCCH). FIG. 5 reveals an instance wherein a reference sign and a management channel are organized in a downlink subframe of 3GPP LTE.
FIG. 7 reveals an instance of a physical useful resource block (PRB) pair. FIG. 10 reveals an example of a subframe structure of a single service system and a service aggregation system. FIG. Eleven exhibits an example of a subframe construction of a 3GPP LTE-A (superior) system that's cross-carrier scheduled by a service indicator discipline. FIG. 13 illustrates a channel measuring technique in a wireless communication system in line with 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 applied. CDMA could also be applied by a radio know-how such as common terrestrial radio access (UTRA) or CDMA2000. TDMA could also be applied with wireless applied sciences resembling global system for cellular communications (GSM) / common 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), and iTagPro features the like.
UTRA is a part of a universal cell telecommunications system (UMTS). Third technology partnership mission (3GPP) long term evolution (LTE) is a part of advanced UMTS (E-UMTS) utilizing evolved-UMTS terrestrial radio access (E-UTRA), which employs OFDMA in downlink and SC in uplink -FDMA is adopted. LTE-A (advanced) is the evolution of 3GPP LTE. It may be known as different phrases similar to digital assistant, wireless modem, handheld machine. NodeB (eNB), a base transceiver system (BTS), an access level (AP), and the like. LTE contains LTE and / or LTE-A. 1 reveals a radio frame structure in 3GPP LTE. One subframe contains two consecutive slots. TTI could also be referred to as a scheduling unit for knowledge transmission. One slot features a plurality of orthogonal frequency division multiplexing (OFDM) symbols in the time domain and a plurality of subcarriers within the frequency domain. OFDM symbol is used to characterize one symbol period since 3GPP LTE makes use of OFDMA in downlink, and may be called a distinct title in keeping with a a number of entry scheme.
SC-FDMA when SC-FDMA is used as an uplink a number of entry scheme, the OFDM image could also be referred to as an SC-FDMA symbol. FIG. 1 is merely an instance. Accordingly, the variety of subframes included in the radio body, the variety of slots included in the subframe, or the variety of OFDM symbols included within the slot could also be variously changed. 3GPP LTE defines that one slot contains 7 OFDM symbols in a standard cyclic prefix (CP), and one slot includes 6 OFDM symbols in an extended CP. FIG. 2 exhibits an instance of a resource grid for one downlink slot. OFDM symbols within the time area and consists of N RB RBs within the frequency domain. N RB of useful resource blocks included within the downlink slot relies on a downlink transmission bandwidth set in a cell. One RB iTagPro features a plurality of subcarriers within the frequency area. Each component on the resource grid is named a resource aspect (RE).
