The problem of radio resource of distribution is more than the limit of power of UE.Network side equipment in the embodiment of the present invention specifically can be base station
Deng.In the embodiment of the present invention, UE can initiate random access when needing to be attached to network, can also needs and network side into
Random access is initiated when row business data transmission, is not limited here.
Optionally, the tenability information of the UE includes one of following information or a variety of:
The type information of the UE；
The transport block size TBS that the UE is supported is no more than setting bit number；
The Physical Resource Block PRB number that the UE is supported is no more than setting number；
The PRB range that the UE is supported.
In the specific implementation process, UE can be only to one of network side equipment instruction above- mentioned information, can also be to net
Network side apparatus indicates a variety of in above- mentioned information；For example, UE can indicate the type information of itself to network side equipment, such as to net
Network side apparatus indicates that the UE that itself is category0, network side equipment are suitble to wireless according to the type of the UE for UE distribution
Resource, for example distribute TBS for the UE and be not more than 1000 bits, it is not more than 6 for the PRB number of UE distribution, or distribute for the UE
6 PRB etc. positioned at bandwidth of cell center；
For another example, UE can also indicate that the TBS that the UE is supported is set no more than bit number, network side is set to network side equipment
The standby instruction according to the UE, the transmission block for UE distribution no more than setting bit number, meanwhile, network side equipment can also basis
The instruction of UE speculates other tenability information of the UE, for example deduces the UE that the UE is category0, the object which supports
Resource block PRB number is managed no more than setting number, PBR range (specific several PRB) which is supported etc., network side equipment
It can be that the UE is distributed at this according to other tenability information of the UE of the tenability information and supposition that UE is directly indicated
Radio resource in the limit of power of UE；
Similarly, UE can also indicate that the PRB number that the UE is supported is not more than setting number or the UE branch to network side equipment
Several specific PRB held etc., correspondingly, the implementation of network side equipment is similar to foregoing description, and which is not described herein again.
In the embodiment of the present invention, UE indicates to divide below there are many modes of the tenability information of UE to network side equipment
It does not mentionlet alone bright:
Mode one is established in connection and adds indicating bit in request message；
Specifically, the UE indicates the tenability information of the UE to the network side equipment, comprising:
The UE sends the RRC connection comprising instruction information to the network side equipment and establishes request message；The instruction
Information is used to indicate the tenability information of the UE.
In the specific implementation process, the UE of category0 determine need to access network after, to network side equipment initiate with
Machine access, specifically, UE sends random access lead code (Random Access Preamble, RAP) to network side equipment,
After the random access response (Random Access Response, RAR) for receiving network side equipment reply, to network side equipment
It sends RRC connection and establishes request message, and establish addition instruction information, the instruction information in request message in the RRC connection and use
In the tenability information of instruction UE, for example, can indicate that the type of UE is category0, distribution nothing can also be directly indicated
Qualifications when line resource, for example, the TBS that can be designated as UE distribution does not exceed 1000 bits, for the PRB of UE distribution
Number does not exceed 6, can be designated as several specific PRB etc. of UE distribution；
In the above method, specific indicating mode, which can be to establish in request message in the RRC connection, adds new letter
Interest statement member (Information Element, IE) indicating bit, for example the indicating bit of 1 bit is added, or can establish and ask in connection
It asks and adds instruction in cause value, or the control of media access control layer (Media Access Control, MAC) can be passed through
Cell (Control Element, CE) indicates that implementation is more, does not limit in the embodiment of the present invention；
Network side equipment is established according to the RRC connection and is requested after request message is established in the RRC connection for receiving UE transmission
Instruction information in message determines the tenability information of UE, it is subsequent be the UE distributing radio resource when, for the UE distribution exist
Radio resource within the scope of the tenability of the UE, for example, determining that UE is category0's according to the instruction in the message
After UE, the TBS for the maximum number bits that it is supported is no more than for UE distribution, number is distributed for the UE and is less than the maximum that the UE is supported
The PRB of PRB number, or select PRB to distribute to the UE etc. from several specific PRB；
In specific implementation, after initiating random access to network side equipment, network side equipment also needs to send out to the UE UE
Random access response is sent, at this moment, network side equipment needs to distribute the UE radio resource for receiving the random access response for the UE,
Since there are no the RRC connections for receiving UE transmission to establish request message at this time for network side equipment, the branch of UE can not be known
Ability information is held, in this case, network side equipment can be UE distribution within the scope of the tenability of category0UE
Radio resource, to avoid the receiving random access response distributed for the UE radio resource not in the tenability range of the UE
Within.
Mode two initiates random access using specific running time-frequency resource；
Specifically, the UE indicates the tenability information of the UE to the network side equipment, comprising:
The UE on running time-frequency resource corresponding with the tenability information of the UE to the network side equipment initiate with
Machine access, so that the running time-frequency resource that the network side equipment occupies when initiating random access according to the UE determines the branch of the UE
Hold ability information.
Optionally, the UE determines the running time-frequency resource according to following steps:
The system message that the UE is sent according to the network side equipment determines the running time-frequency resource.
In the specific implementation process, UE can be on running time-frequency resource corresponding with the tenability information of the UE to network side
Equipment sends random access lead code, and network side equipment determines the UE after the random access lead code for receiving UE transmission
The occupied running time-frequency resource of the random access lead code is sent, and determines the tenability information of the corresponding UE of the running time-frequency resource,
According to the tenability information of determining UE, for the UE distributing radio resource.
In specific implementation, the UE that network side equipment can broadcast category0 by system message initiates random access
When dedicated Physical Random Access Channel (Physical Random Access Channel, PRACH) running time-frequency resource, specifically
Ground, network side equipment can be in system information block 2(System Information Block2, SIB2) public SIB it is wireless
In resource distribution (RadioResourceConfigCommonSIB), and/or, the Physical Random Access Channel configuration of SIB
(Prach-ConfigSIB) Physical Random Access Channel configuration index (Prach- of the addition for Category0UE in
ConfigIndexForUECategory0), come the running time-frequency resource occupied when indicating that Category0UE initiates random access, network
Side apparatus need to guarantee the random access running time-frequency resource of Category0UE when distributing dedicated running time-frequency resource for Category0UE
Position is orthogonal with the random access running time-frequency resource position of other type UE；
After determination needs to access network, the Category0UE broadcasted from system message initiates shared when random access UE
It selects running time-frequency resource to send random access lead code to network side equipment in running time-frequency resource, and is receiving network side equipment
After the random access response of reply, RRC connection is sent to network side equipment and establishes request message；
Network side equipment sends the random access preamble according to the UE after the random access lead code for receiving UE initiation
The occupied running time-frequency resource of code determines the tenability information of the UE, that is, determining that the type of the UE is Category0, UE branch
The transport block size TBS held is not more than setting number, UE no more than setting bit number, UE the Physical Resource Block PRB number supported
The several specific PRB etc. supported, after network side equipment determines the tenability information of the UE, subsequent for the UE or more
In row resource allocation, the radio resource within the scope of the tenability of the UE is distributed for UE；
It should be noted that in addition to the mode broadcasted above by system message makes UE obtain running time-frequency resource, it can also be
Prespecified setting type UE initiates the running time-frequency resource occupied when random access in agreement, namely is appointed in advance by network side and the side UE
It sets, but the changeability of this mode or flexibility are poor.
In specific implementation, network side equipment is successfully established after RRC connect with UE, can be sent to the UE and be obtained UE's
The solicited message of tenability information, the tenability information that network side equipment can be replied according to the UE, further verifying should
The type of UE, it is determined whether need to also distribute subsequent radio resource according to the limitation for being directed to category0UE for it.Here
Mainly in view of the UE of lowest version possibly can not identify the system message of network side equipment broadcast, on using
It states running time-frequency resource and initiates random access, so, network side equipment can be successfully established after RRC connect with UE, obtain the UE's
Tenability information determines subsequent resource allocation policy according to the tenability information.
Mode three selects specific leading code character (preamble group) or lead code (preamble), to network side
Equipment initiates random access；
Specifically, the UE indicates the tenability information of the UE to the network side equipment, comprising:
The UE selects lead code from leading code character corresponding with the tenability information of the UE, to the network side
Equipment initiates random access, so that the lead code where the random access lead code that the network side equipment is sent according to the UE
Group determines the tenability information of the UE；Or,
The UE selects lead code corresponding with the tenability information of the UE, initiates to the network side equipment random
Access, so that the network side equipment determines that the tenability of the UE is believed according to the random access lead code that the UE is sent
Breath.
Optionally, the UE determines the corresponding leading code character of tenability information of the UE or leading according to following steps
Code:
The system message that the UE is sent according to the network side equipment determines that the tenability information of the UE is corresponding
Leading code character or lead code.
In the specific implementation process, UE, can be from corresponding with the type of the UE leading after determining and needing to access network
Lead code is selected in code character, initiates random access to network side equipment, network side equipment is in the random access for receiving UE transmission
After lead code, the tenability information of the corresponding UE of leading code character where the lead code is determined, initiate to connect at random for example, determining
The type of the UE entered is category0, determines that the transport block size TBS that UE is supported is not more than the object for setting bit number, UE support
Resource block PRB number is managed no more than setting number, determines several specific PRB etc. that UE is supported, network side equipment determines the UE
Tenability information after, in the subsequent uplink and downlink resource allocation for the UE, for UE distribution the UE tenability model
Enclose interior radio resource；Or,
UE can choose lead code corresponding with the type of the UE, to network side equipment after determination needs to access network
Random access is initiated, network side equipment determines the corresponding UE of the lead code after the random access lead code for receiving UE transmission
Tenability information, for example, determine initiate random access UE type be category0, determine UE support transmission block
Size TBS is not more than setting number no more than setting bit number, UE the Physical Resource Block PRB number supported, determines what UE was supported
Several specific PRB etc., after network side equipment determines the tenability information of the UE, in the subsequent uplink and downlink resource for the UE
In distribution, the radio resource within the scope of the tenability of the UE is distributed for the UE；
In specific implementation, when can initiate random access by system message broadcast setting type UE by network side equipment
Lead code or specific preamble in the particular preamble code character of use, can also prespecified setting type UE(be such as in the protocol
Category0 type UE) initiate lead code or specific preamble when random access in the particular preamble code character that uses, implementation
It is not unique.
In specific implementation, network side equipment is successfully established after RRC connect with UE, can be sent to the UE and be obtained UE's
The solicited message of tenability information, the tenability information that network side equipment can be replied according to the UE, further verifying should
The type of UE, it is determined whether need to also distribute subsequent radio resource according to the limitation for being directed to category0UE for it.Here
Mainly in view of the UE of lowest version possibly can not identify the system message of network side equipment broadcast, on using
It states running time-frequency resource and initiates random access, so, network side equipment can be successfully established after RRC connect with UE, obtain the UE's
Tenability information determines subsequent resource allocation policy according to the tenability information.
Mode four, refusal carry out data biography on the radio resource beyond self-ability range that network side equipment distributes
It is defeated；
Specifically, the UE indicates the tenability information of the UE to the network side equipment, comprising:
The UE when determining the radio resource of network side equipment distribution not within the scope of the tenability of the UE,
Refusal carries out data transmission on the radio resource that the network side equipment distributes, so that the network side equipment is described in the determination
UE redistributes for the UE in setting type not when carrying out data transmission on the radio resource for distributing to the UE before
UE tenability within the scope of radio resource, and determining that the UE can be in the radio resource for being reassigned to the UE
On carry out data transmission after, determine the UE tenability information be it is described setting type UE tenability information.
In the specific implementation process, UE is in the uplink/downlink radio resource of the network side equipment distribution received not at this
When within the scope of the tenability of UE, it can refuse to send upstream data on the ascending resource or receive downlink data；Work as network
Side apparatus discovery fails to detect the upstream data or fail to receive UE to network that UE is sent on the radio resource distributed
When the feedback information for the downlink data that side apparatus is sent, then it can be redistributed for the UE in setting type UE, such as
Radio resource within the scope of category0UE tenability；After being again the UE distributing radio resource, if redistributing
The upstream data or the feedback for receiving the downlink data that UE sends network side equipment that UE is sent are detected on radio resource, then
The type for determining the UE is category0, then in the subsequent radio resource allocation for the UE, according to category0UE
Tenability range be allocated；
It is successfully established after RRC connect in the network side equipment and UE, which can directly send to UE and obtain
The request of the tenability information of the UE, at this moment, the tenability information that can be sent further according to UE distributes subsequent nothing for the UE
Line resource.
