With the construction of intelligent grid, need of the business such as generating, transmission of electricity, distribution, electricity consumption to wireless private network throughput of transmissions Continuous growth is asked, following National Radio management board may be that power industry distributes one section of continuous frequency spectrum resource, with lifting The transmission rate of electric power wireless private network, meet the transmission demand of power business.Continuous frequency spectrum resource distribution includes two kinds of situations, As shown in Figure 2：It is special that the continuous frequency spectrum resource of a part in (1) 223~235MHz frequency ranges is fully allocated to power industry, its He must not use industry.(2) power industry and whole frequency spectrum resources in the shared 223~235MHz frequency ranges of other industry or one Point continuous frequency spectrum resource, resource coordination is carried out by management or technological means between industry, avoids influencing each other.

LTE down control channels include：Physical Control Format Indicator Channel (english abbreviation：PCFICH, English full name： Physical Control Format Indicator Channel), indicate to transmit PDCCH with how many individual OFDM symbols.Thing Manage layer hybrid automatic repeat request indication channel (english abbreviation：PHICH, English full name：Physical hybrid ARQ Indicator Channel), for feeding back uplink HARQ (english abbreviations：HARQ, English full name：Hybrid Automatic Repeat Request) receive result.Physical downlink control channel PDCCH, indicate corresponding PDSCH information and other controls Information.Physical Broadcast Channel (english abbreviation：PBCH, English full name：Physical Broadcast Channel), for transmitting The Physical Broadcast Channel of MIB information.Down control channel is carried including uplink data scheduling information, downlink data Transmit a variety of Downlink Control Information including configured information, common control information, uplink power control commands etc..Transmission, which is put, to be passed through Down control channel sends Downlink Control Information to recipient, and recipient can perform corresponding order after receiving this information.Specifically Ground, base station to terminal send transmitting uplink data use physical resource, modulation coding mode, power control information, HARQ phases The Downlink Control Information such as information and aperiodic channel status instruction request command is closed, UE can be transmitted after parsing these information Row data；Base station to terminal send downlink data use physical resource configured information, modulation coding mode, HARQ information, number According to Downlink Control Information such as power excursions, UE just can be in demodulation downlink shared data channel after parsing these information；In addition it is The common control informations such as system broadcast control information, Stochastic accessing, paging and upper and lower power control command are also required to by descending control Channel processed is sent to terminal.It can be seen that being sent to UE by sending Downlink Control Information, UE can be controlled to perform corresponding order.

To during 4G evolution, 3GPP LTE system is operated on one section of continuous frequency spectrum 3G, a DCI corresponding one Individual PDCCH channels, control channel resource element (english abbreviation：CCE, English full name：Control Channel Element) it is main It is used in DCI to PDCCH mapping process, is more effectively to configure the time-domain resource of various channels, it is necessary to define suitably Control channel resource element CCE, DCI through-rate match the integral multiple that signal length is adjusted to CCE, according to certain mapping Rule is by multiple DCI information combinations and is mapped in PDCCH sequences, completes transmission channel to the mapping process of physical channel.1 CCE includes 9 continuous resource element groups (english abbreviations：REG, English full name：Resource Element Groups), 1 REG includes 4 RE, and control channel takes preceding 1~4 OFDM (english abbreviation of time domain：OFDM, English full name： Orthogonal Frequency Division Multiplexing) symbol, its symbolic number specifically taken is by physical layer control The CFI information instruction of format indication channel PCFICH processed carrying, using not accounted in whole frequency range by PCFICH and PHICH on frequency domain REG, control channel have four kinds of forms, can be with the multiple PDCCH channels of concurrent multiplexing in a subframe.Son on each symbol Number of carrier wave is few, it is therefore desirable to which more symbols carry PDCCH control information, when the OFDM for distributing to control channel is more When, CCE is more.

When the system is applied into 230MHz frequency ranges, using OFDM, height on the discrete frequency for distribute to electricity usage Contrast system and carrier aggregation technology, 40 frequencies are aggregated into 1MHz bandwidth, in the bandwidth maximum rate up to 1.76Mbps, For each 25kHz as a single subband, each sub-band division is 11 2kHz subcarrier in LTE230 systems, remaining Guard bands of the 3kHz as subband, each subband use the channel architecture similar with LTE, accounted on its down control channel frequency domain According to a subband, the frequency spectrum service condition of each subband is as shown in Figure 3.
