Description
Technical field
The present invention relates to the communications field, particularly a kind of method of definite terminal works bandwidth and terminal.
Background technology
Technology of Internet of things is in the ascendant, 3-G (Generation Three mobile communication system) with and long evolving system (Long Term Evolution needs to support MTC(Machine Type Communications in LTE), the communication of machine type) function.A MTC equipment (MTC terminal) may have multiple little bandwidth system (machine and machine, Machine to Machine) the part characteristic among the communication characteristic is little, insensitive to communication delay as Hypomobility, transmitted data amount, require features such as extremely low power dissipation.
Machinery compartment (Machine-to-machine, M2M) communication is as a kind of novel communication theory, its objective is that the communication technology with number of different types organically combines, as: machine is to machine communication, machine control communication, man-machine interaction communication, mobile interconnected communication, thus the development of promotion social production and life style.
Current mobile communications network is at interpersonal design of communication, as determining etc. of: network capacity.Support little bandwidth system communication just need be optimized if wish to utilize mobile communications network according to the characteristics of little bandwidth system communication mechanism to mobile communication system, so that can not be subjected to or be subjected to realize little bandwidth system communication better under the less situation about influencing to traditional person to person's communication.
Some characteristics that the current MTC communication of recognizing may exist have:
-MTC terminal has Hypomobility;
The time that-MTC terminal and network side carry out transfer of data is controlled; Be that the MTC terminal can only insert in the time period of network appointment;
The transfer of data that-MTC network and network side carry out is less demanding to real-time to transfer of data, has the time tolerance that is:;
-MTC terminal energy constraint requires extremely low power consumption;
Only carry out the message transmission of small data quantity between-MTC terminal and the network side;
-MTC terminal can be that unit manages with the group;
……
The MTC terminal of a reality can have above-mentioned one or more characteristics.
MTC equipment after considering in the little bandwidth system communication can be very huge, and the function of most occasion MTC equipment is single relatively, does not need very high transmission rate, needs therefore to consider that the cost to MTC equipment further reduces.Bandwidth is the key factor that influences the MTC equipment cost, if can suitably reduce the bandwidth of operation of MTC equipment, can significantly reduce cost.
The system bandwidth of existing LTE system has several values as shown in table 1:
Table 1
Network can be by the Master Information Block MIB(Master Information Block in the system broadcasts) the downlink system bandwidth of notifying cell, if up-link bandwidth and downlink system bandwidth are unequal, then also can pass through SIB2(System Information Block Type2) the up-link bandwidth of notifying cell.
The LTE descending sub frame comprises control area and the data area of time-division, as shown in Figure 1.Generally, the control area takies preceding 1 ~ 3 symbol of a descending sub frame, bearing downlink control signaling, comprise Physical Control Format Indicator Channel (PCFICH, Physical control format indicator channel), Physical Downlink Control Channel (PDCCH, Physical Downlink Control Channel) and the automatic request retransmission indicating channel of physical mixed (PHICH, Physical HARQ indication channel).Wherein, PCFICH notifies descending control area shared symbol numbers, and it is mapped on 4 resource unit group (REG, Resource element group) that equidistantly are distributed in the whole downlink system bandwidth; PHICH is used for carrying (ACK/NACK) information of replying at Uplink Shared Channel (UL-SCH) packet, and it is mapped on 3 REG, and these REG also as far as possible equidistantly distribute in system bandwidth; PDCCH is used for bearing downlink control information (DCI, Downlink Control Information), after all PDCCH are multiplexing, interweaves on PCFICH and the PHICH residual resource and the resource mapping regional the removing of The whole control.
Ascending control channel Physical Uplink Control Channel among the LTE (PUCCH, Physical Uplink Control Channel) is used to transmit the ascending control information relevant with this user's downlink data.From a user's angle, its PUCCH occupies a Resource Block (Resource Block, RB) Dui Ying frequency domain resource on frequency domain; On time domain, then take a subframe transmission.In order to obtain frequency diversity gain, the PUCCH of two time slots also need carry out the frequency hopping transmission.In order to obtain big as far as possible frequency diversity gain, PUCCH is positioned at the two ends of upstream band, as shown in Figure 2.
From as can be seen above-mentioned, the mapping of the resource of several main control channel of LTE is all closely related with system bandwidth.For guarantee that UE all can correctly receive/transmit control channel under all system bandwidths, all UE of LTE standard-required need support the 20M system bandwidth.The bandwidth that is the UE support is always more than or equal to system bandwidth, and therefore, the bandwidth of operation of terminal in system just equals the system bandwidth of system broadcasts notice.
Prior art is based on bandwidth that terminal supports necessarily more than or equal to the system bandwidth design, and the bandwidth of operation of terminal just equals the system bandwidth of system broadcasts notice.And the bandwidth of MTC equipment support may reduce, and the situation of the bandwidth of terminal support less than system bandwidth promptly may occur.At this moment, because system bandwidth surpasses the maximum bandwidth that terminal is supported, terminal can't work under the system bandwidth.It is at the special information fields such as control domain of little bandwidth terminals design, so that little bandwidth terminals can be operated under the large bandwidth system in large bandwidth system that a kind of potential scheme is arranged.But owing in the network design of reality, the bandwidth of each sub-district may be different, and how working under the sub-district of different bandwidth at little bandwidth terminals, scheme can be not for reference.
