In embodiments of the present invention, MTC can be divided according to the degree of the enhancing of coverage area required for MTC UE The classification of UE, naturally it is also possible to be divided according to other indexs such as the types of service of MTC UE carrying, mainly be increased below with covering It is illustrated for strong measurement.The intensity (measurement) of coverage enhancement required for the preferable MTC UE of communication environment also compares It is small or even suitable with common (Legacy/Normal) UE.And the MTC UE poor for communication environment, such as it is located underground, or The MTC UE that person is isolated etc. by metal shell, then need biggish coverage enhancement to guarantee normally to communicate.

Specific division methods can be pre-defined by system or agreement, or be carried out by the superior node of base station or base station Configuration.In the case where system or pre-defined agreement, the division methods of system or agreement MTC UE classification predetermined are same Sample, which is pre-configured, gives MTC UE, then without executing step 301.And in the case where being configured by base station, base station can from it is local or on Grade node obtains or the division methods of configuration MTC UE classification, and generates classification instruction information and be handed down to MTC UE, that is, It says and needs to be implemented step 301.

Specifically, when step 301 needs to be implemented, classification can be indicated the instruction MTC UE classification that information include by base station The parameter of division is in the form of information element (Information Element, IE) or label (Flag), by radio resource control System (Radio Resource Control, RRC) signaling bear is sent by system broadcasts.Category division parameter can be The intensity of coverage strength required for MTC UE or coverage enhancement can be measured.Such as path loss (Path Loss, PL), Reference Signal Received Power (Reference Signal Receive Power, RSRP), Reference Signal Received Quality (Reference Signal Receive Quality, RSRQ), channel quality indicate (Channel Quality Indicator) etc..By taking PL as an example, base station can be determined according to the pre-defined of system or agreement or voluntarily configuration for referring to Show or configure the IE of PL threshold value, the pseudocode of the IE can be such that

Wherein, SystemInformationBlockType n indicates that above-mentioned pseudocode is present in system information block SIBn, Such as SIB1；R1, r2 are integers, and r2 is greater than r1；INTEGER (r1..r2) indicates that IE can be indicated in this section r1 to r2 Arbitrary integer；ENUMERATED a1, a2, a3 ... ..., an indicate enumerate set a1, a2, a3 ... ..., an in one A element.If PL threshold value has multiple (such as P), IE can use ceil (log₂(P)) a bit indicates or configures one PL range rounds up to x as thresholding, here ceil (x) expression.Unless otherwise specified, PL threshold value is exactly IE instruction Value.It is of course also possible to which regulation PL threshold value is the value of IE instruction and the product of a constant.This constant can be predefined with system , it is also possible to base station configuration.Such as predefine this constant equal to 2, then the value that PL threshold value=2*IE is indicated.Following puppet generations Code illustrates that the IE for including in SIBn and instruction step-length step, the IE and step are used to indicate or configure PL threshold value:

Base station can also be configured to indicate that or configure the IE of PL range index, if system or base station preset or configure R path loss range, then IE can use ceil (log₂(R)) a bit indicates or configures a path loss range rope Draw, ceil (x) expression here rounds up to x.The pseudocode of the IE can be such that

PL_range x or PL_range (x) indicate path loss range x in above-mentioned pseudocode, it may be assumed that path loss range 0, path loss range 1 or path loss range 2 etc..Therein 0,1,2 be PL range index.Specifically, it such as presets Or configuration path exhaustion range 0 is (1dB-5dB), path loss range 1 is (6dB-10dB), and path loss range 2 is (11dB-15dB), path loss range 3 are (16dB-20dB), then base station can indicate above 4 ranges by bit value:

IE bit status	PL range	The index of PL range
			00	1dB-5dB	0
01	6dB-10dB	1
			10	11dB-15dB	2
11	16dB-20dB	3

302, MTC UE determine the first parameter, and determine generic according to identified first parameter

MTC UE could further obtain corresponding system information it needs to be determined that the classification of oneself according to classification.When When above-mentioned steps 301 execute, MTC UE can be broadcasted by resolution system obtains classification instruction information therein, is referred to according to classification Show that threshold type or the category division parameter in information determine the type or the attribute (type and valve of the first parameter of the first parameter Value Types are identical or the type of the first parameter is identical as type indicated by category division parameter), and determine first ginseng Number, for example, MTC UE determines oneself PL between base station as the first parameter when category division is PL threshold value.Work as step 301 when not executing, and MTC UE category division (i.e. threshold type) is then preset by system or agreement and is stored in MTC UE sheet Ground, then MTC UE can it is in office when machine determine the first parameter and determine oneself described in classification, such as initiate random access, stop Dormancy state terminates to be waken up, carries out cell switching cell gravity treatment waiting time.

MTC UE determines the first parameter of oneself, comprising: PL or PL range index, RSRP or RSRP range index, or RSRQ or RSRQ range index or CQI or type of service or type of service index or Power Saving Class or Power Saving Class rope Draw or power class Power Class or Physical Random Access Channel (Physical Random Access Channel, PRACH) resource index or PRACH preamble index or PRACH root sequence index or the length of narrowband resource index or spreading code Degree or number of repetition or binding Transmission Time Interval size (TTI Bundling Size) or number of retransmissions etc., and wherein Any several combinations.The type of first parameter can be determined according to the IE received, be also possible to system or agreement is preparatory It is defined.

By taking path loss as an example, the difference of transmission power when MTC UE can be according to RSRP and base station transmission reference signal It determines oneself PL between base station, is compared later with the PL threshold value that the IE obtained from SIBn is included, the class compared Type can have be greater than compare, less than compare, equal to compare, more than or equal to compare, less than or equal to comparing, and comparative type can be by System or agreement are prespecified.For example, can specify that comparative type is greater than comparing, when the PL that MTC UE is measured is less than PL threshold value When, comparison result be it is true or, the MTC UE be first kind MTC UE, when the PL that MTC UE is measured be greater than PL threshold value when, compare It as a result is vacation or no, which is the second class MTC UE, and vice versa, will not enumerate herein.

By taking coverage enhancement value as an example, MTC UE needs first to measure the path loss between base station, the road where determining later Diameter exhaustion range, to determine coverage enhancement value according to prespecified corresponding relationship.Wherein path loss range and covering increase The corresponding relationship of intensity values can be prespecified by system or agreement, such as the coverage enhancement of regulation path loss range 1dB to 5dB Value is 1, and the coverage enhancement value of path loss range 6dB to 10dB is 2 etc..In addition, for corresponding with coverage enhancement value It can also be RSRP, RSRP range, RSRQ, RSRQ range, CQI, CQI range or successfully detect used in prespecified channel Number etc., wherein prespecified channel can be synchronizing channel or Physical Broadcast Channel, or the PDSCH of carrying SIB1, or Dispatch the control channel of SIB1, or the PDSCH of carrying SIB2, or the control channel etc. of scheduling SIB2.Finally, MTC UE is according to survey The coverage enhancement value (the first parameter) obtained is compared with the coverage enhancement value (threshold value) obtained from IE, and then determines oneself Classification.

Comparative type can also compare for matching, for example, when the threshold value in IE is type of service or Power Class, The type of service or Power Class that MTC UE also correspondingly determines oneself as the first parameter, later with the threshold value in IE into Row matching is compared, so that it is determined that the classification of MTC UE.

Furthermore, it is possible to determine the classification of MTC UE according to UE category belonging to MTC UE, such as can set in advance Determine the class (category) of UE, the class of category1, category2, category3 etc., UE can be from function, ability or industry It is divided in business；If setting MTC UE belongs to category1 or category2, which is first kind MTC UE, if MTC UE belongs to category3, then the MTC UE is the second class MTC UE.That is, MTC UE can be according to belonging to oneself Category determine classification.

The system information of 303, base station broadcast MTC UE.

Base station can the classification of according to system or agreement prespecified or oneself configuration MTC UE determine each MTC System information corresponding to UE classification.For example, base station can will be required for all MTC UE when it is two classes that MTC UE, which is divided to, System information is divided into K=M+N system information block, and wherein M system information block includes that the MTC UE of all categories is needed jointly The system information wanted, such as the system information of first kind MTC UE and the second class MTC UE common need, N number of system information block is only System information required for a kind of MTC UE comprising classification, such as only include the system information of first kind MTC UE.Similarly, such as Fruit MTC UE is divided into 3 classes, then K=M+N+O includes whole system information required for three classes MTC UE, and N and O system letter Breath block then separately includes the system information of one type or two class MTC UE, and so on.

By taking two class MTC UE as an example, in M system information block of base station configuration shared by least one information block transmission Resource is that system is preset, comprising: time span that the start time of information block transmission, block of information single transmission occupy, Frequency location that the time interval of information block transmission or period, block of information single transmission occupy, block of information single transmission occupy One or more of frequency resource size.

For example, system can be with time span that presupposed information block single transmission occupies L subframe, information block transmission when Between be spaced or the period be frequency location that T radio frames, block of information single transmission occupy is a fixed position (in such as on frequency band The heart) narrowband, the frequency resource size that occupies of block of information single transmission be F PRB.Wherein, L, T, F are preset fixations Positive integer.System further presets fixed sub-frame offset subframe_offset and radio frames biasing radioframe_ Offset can determine the start time of information block transmission based on subframe_offset and radioframe_offset.Such as, Subframe index index and frame index index locating for the start time of information block transmission will meet following relationship:
