Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.

As shown in Figure 1, be the resource allocation methods flow chart based on UE side that the embodiment of the present invention one provides, comprise the following steps:

S101:UE determines to need access network;

S102: described UE is successfully setting up before RRC is connected with network equipment, indicating the tenability information of described UE to described network equipment, is the Radio Resource that described UE is distributed within the scope of the tenability of described UE to make described network equipment according to the tenability information of described UE.

In the embodiment of the present invention, after UE determines to need access network, successfully setting up before RRC is connected with network equipment, just to the tenability information of network equipment instruction self, thus make the tenability information that network equipment can provide according to UE, be distributed in the Radio Resource within the scope of the tenability of this UE for UE, thus the Radio Resource that network equipment can be avoided to distribute to UE is more than the problem of the limit of power of UE.Network equipment in the embodiment of the present invention can be specifically base station etc.In the embodiment of the present invention, UE can initiate Stochastic accessing when needs are attached to network, also can initiate Stochastic accessing when needs and network side carry out business data transmission, not limit here.

Alternatively, the tenability information of described UE comprises one or more in following information:

The type information of described UE;

The transmission block size TBS that described UE supports is not more than setting bit number;

The Physical Resource Block PRB number that described UE supports is not more than setting number;

The PRB scope that described UE supports.

In specific implementation process, UE only can indicate the one in above-mentioned information to network equipment, also can indicate in above-mentioned information to network equipment multiple; Such as, UE can indicate self type information to network equipment, as indicated from the UE as category0 to network equipment, network equipment is according to the type of this UE, for this UE distributes the Radio Resource be applicable to, such as be not more than 1000 bits for this UE distribution T BS, the PRB number distributed for this UE is not more than 6, or divides 6 PRB etc. being coordinated in bandwidth of cell center for this UE;

For another example, the TBS that UE also can indicate this UE to support to network equipment is not more than setting bit number, network equipment is according to the instruction of this UE, for this UE distributes the transmission block being not more than setting bit number, simultaneously, network equipment can also infer other tenability information of this UE according to the instruction of UE, such as infer and the UE that this UE is category0, the Physical Resource Block PRB number that this UE supports is not more than setting number, the PBR scope (specific several PRB) etc. that this UE supports, other tenability information of this UE of the tenability information that network equipment directly can indicate according to UE and supposition is the Radio Resource that this UE is distributed in the limit of power of this UE,

In like manner, the PRB number that UE can also indicate this UE to support to network equipment is not more than several specific PRB etc. of setting number or this UE support, and correspondingly, the enforcement of network equipment is similar to foregoing description, repeats no more here.

In the embodiment of the present invention, UE has multiple to the mode of the tenability information of network equipment instruction UE, illustrates respectively below:

Mode one, in connection establishment request message, add indicating bit;

Particularly, described UE indicates the tenability information of described UE to described network equipment, comprising:

In specific implementation process, the UE of category0 is after determining to need access network, Stochastic accessing is initiated to network equipment, particularly, UE sends random access lead code (Random Access Preamble to network equipment, RAP), receiving accidental access response (the Random Access Response of network equipment reply, RAR) after, RRC connection establishment request message is sent to network equipment, and indication information is added in this RRC connection establishment request message, this indication information is used to indicate the tenability information of UE, such as, the type of UE can be indicated to be category0, directly can also indicate qualifications during distributing radio resource, such as, the TBS that can be designated as this UE distribution does not exceed 1000 bits, the PRB number distributed for UE does not exceed 6, several specific PRB etc. that this UE distributes can be designated as,

In aforesaid way, concrete indicating mode can be add new information unit (Information Element in this RRC connection establishment request message, IE) indicating bit, such as add the indicating bit of 1 bit, or instruction can be added in connection establishment request cause value, maybe can pass through media access control layer (Media Access Control, MAC) control cell (Control Element, CE) indicate, implementation is more, does not limit in the embodiment of the present invention;

Network equipment is after the RRC connection establishment request message receiving UE transmission, according to the indication information in this RRC connection establishment request message, determine the tenability information of UE, follow-up be this UE distributing radio resource time, the Radio Resource within the scope of the tenability of this UE is distributed in for this UE, such as, according to the instruction in this message, determine that UE is after the UE of category0, for this UE distributes the TBS being no more than the maximum number bits that it is supported, for this UE distribution number is less than the PRB of the maximum PRB number that this UE supports, or select PRB to distribute to this UE etc. from several specific PRB,

In concrete enforcement, UE is after initiating Stochastic accessing to network equipment, network equipment also needs to send accidental access response to this UE, at this moment, network equipment needs for this UE distributes this UE Radio Resource receiving this accidental access response, because network equipment does not now also receive the RRC connection establishment request message of UE transmission, therefore the tenability information of UE cannot be known, in this case, network equipment can be distributed in the Radio Resource within the scope of the tenability of category0UE for this UE, to avoid the Radio Resource of the receiving random access response distributed for this UE not within the tenability scope of this UE.

Mode two, adopt specific running time-frequency resource initiate Stochastic accessing;

Particularly, described UE indicates the tenability information of described UE to described network equipment, comprising:
