Step 102, base station (eNB) generates the MIB that comprises the Physical Downlink Control Channel configuration information;
This Physical Downlink Control Channel is the Physical Downlink Control Channel that is exclusively used in Machine Type communication, for example, Physical Downlink Control Channel takies k to k+y symbol of x subframe in time domain, take z subcarrier at frequency domain, informational needs such as x, k, y, z transmit by the MIB of carrier wave, newly-increased x, k, information such as y, z can also be carried the information such as System Frame Number that Physical Downlink Control Channel can occur among the MIB in addition in MIB.
Particularly, the mode of newly-added information mainly contains in MIB:
(a) increase a plurality of bits of the described configuration information of expression in MIB, the MTC terminal is informed in initial (perhaps finishing) position of the subcarrier that x, y, z and k and Physical Downlink Control Channel is shared of demonstration;
For example, adopt 10 bits to represent these information.At first the value that may occur is mated with different bits, and this matching result MTC terminal and base station learn that in advance for example the value of x may be 3 and 7, can adopt 1 bit to represent the x value so, and 1 represents x=3, and 0 represents x=7;
(b) calculate a parameter of configuration information correspondence according to predefined corresponding relation, described parameter is joined among the MIB, and the MTC terminal is informed in initial (perhaps finishing) position of the latent subcarrier that x, y, z and k and Physical Downlink Control Channel is shared that shows;
Because consider that the MIB reserved bit is less, so except demonstration is informed, thereby can also adopt the latent mode of showing to transmit the purpose that realizes saving bit;
For example, only transmit a value R among the MIB, the MTC end side calculates the information such as initial (perhaps finishing) position of the shared subcarrier of x, y, z and k and Physical Downlink Control Channel by the R value.X=(R mod 2)+3 for example, k=4, y=R, z=(R mod 7) begins to get altogether z carrier wave and the starting and ending position that takies carrier wave can be middle subcarrier (if middle be two subcarriers, then get low that of frequency) from carrier wave;
(c) put information setting for many assembly and identify accordingly, in MIB, increase described sign,
For example, preestablish a configuration information table, every assembly is put in the information in the table, the value of x, k, y, z is determined, the corresponding sign of information is put in every assembly, this configuration information table is stored in base station and MTC terminal simultaneously, transmits a sign among the MIB, and the MTC terminal can find the configuration information of corresponding group by this sign.
In addition, except carrying the control channel relevant information by main system information, the information such as System Frame Number that can also can occur by initial (perhaps finishing) position and the control channel of the mode of arranging the in advance subcarrier that x, y, z, k and physical control channel is shared store base station and MTC terminal into.
Same, System Frame Number information also can be issued the MTC terminal by above-mentioned multiple mode in MIB.
Step 104, the base station sends to the MTC terminal with MIB;
Step 106, MTC terminal parses MIB obtains the Physical Downlink Control Channel configuration information, and the MTC terminal is resolved MIB based on several modes of newly-added information among the above-mentioned MIB;
Step 108, the base station sends Downlink Control Information at this Physical Downlink Control Channel, and the MTC terminal receives the Downlink Control Information of this Physical Downlink Control Channel carrying at this Physical Downlink Control Channel.
Present embodiment machine terminal communication means, the base station sends to terminal by the MIB that will comprise the Physical Downlink Control Channel configuration information, the MTC terminal can be according to this configuration information, to Physical Downlink Control Channel, receive Downlink Control Information, this Physical Downlink Control Channel can be in some system-frame some symbol of some subframe occur, can take simultaneously the part of carrier bandwidths flexibly, namely take the parton carrier wave.Like this, avoid using with of Physical Downlink Control Channel, improve the utilance of resource, realized that the MTC terminal only collects Downlink Control Information on the bandwidth of work carrier wave, thereby when realizing MTC terminal and general commercial terminal common carrier, do not need to improve the radio-frequency receiving-transmitting ability of MTC terminal, reduced the cost of MTC terminal.
