at LTE-Advanced (Long Term Evolution, Long Term Evolution) in system, in order to support the shorter conversion time delay from resting state (Dormant) to state of activation (Active), be in UE (the User Equipment of resting state (Dormant), subscriber equipment) has same eNB (evolved Node B, evolved base station) (the Radio Resource Control of the RRC between, Radio Resource is controlled) connect and the radio bearer of having set up, but owing to not having ascending resource to distribute and transfer of data, currently be in temporary transient unactivated state.
The state that triggers with the upstream data of synchronous regime UE is converted to example, and its flow process comprises the steps: as shown in Figure 1
Step 11: next SR (Scheduling Request, dispatch request) is waited in time-delay.
Step 12:UE sends dispatch request.
The request of step 13:eNB decoding scheduling and allocation schedule mandate.
Step 14: transmitting and scheduling mandate.
Step 15:UE processes.
Step 16:UE transmit ascending data.
Wherein, according to time delay and the cycle of minimum, and do not consider error of transmission, the optimum delay estimation of each step is as follows:
Table 1
The target of current 3GPP LTE-A is to get rid of the impact in DRX (Discontinuous reception, discontinuous reception) cycle, and be 10 milliseconds the change-over time from the resting state to the state of activation.For this target, state conversion process requires further improvement.Transfer of data based on competition (CB:Contention Based) is a kind of effective method.The main thought of the method is can be allowed to transmit ascending data on the ascending resource of competition when UE is current when there is no special-purpose resource.
Its flow process comprises the steps: as shown in Figure 2
Step 21: base station notice UE comprises scheduling identification CB-RNTI (Contention Based-Radio Network Temporary Identity) etc. based on the uplink basic configuration of competition;

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described, by network side or the high-rise configuration information that sends of UE side, this configuration information is for up logic channel, and whether the upstream data of each up logic channel of notice UE MAC layer allows to use competitive resource.UE MAC is according to this, will allow to use the upstream data of the up logic channel of competitive resource to transmit on the competitive resource of authorizing, and forbids not allowing using the upstream data of the up logic channel of competitive resource to transmit on the competitive resource of authorizing.Equipping rules is that expectation is shortened time delay and can be stood the upstream data permission use competitive resource of competitive resource transmission characteristic.
Wherein, whether the upstream data of the up logic channel of notice UE MAC layer allows to use the method that competitive resource is taked to be:
Network side carries configuration information in the configuration signal of UE transmission when carrying out up logic channel configuration; Or
The UE rrc layer is determined corresponding configuration information according to the configuration signal of network side when up logic channel is set up, and sends configuration information with the form of interlayer primitive to UE MAC layer; Or
UE RLC (Radio Link Protocol, radio link control) layer and/or PDCP (PacketData Convergence Protocol, PDCP) layer to the indication information that UE MAC layer sends, carries configuration information in indication information.
Whether upstream data allows to use the principle of competitive resource to be:
AM (AcknowledgedMode, answer-mode) data allow to use, and UM (UnacknowledgedMode, unacknowledged mode) data and TM (TransparentMode, transparent mode) data do not allow to use;
TCP (Transmission Control Protocol, transmission control protocol) the AM data in the up logic channel of downloading service (carrying TCP feedback packet) allow to use, other AM data do not allow to use, and UM data and TM data do not allow to use yet;
Need the AM size of data of transmission to be less than or equal to certain thresholding, the AM data that perhaps just can carry in the competitive resource (namely competing Grants) of one or several mandates could be used competitive resource;
Other expects to shorten time delay as required, and the upstream data that can stand the transmission characteristic of competitive resource allows to use.
First embodiment of the invention is a kind of uplink data transmission method based on competition, comprises as shown in Figure 3:
Step 101: network side sends configuration signal to UE when carrying out up logic channel configuration, be configured for up logic channel 1, indicates the upstream data of this up logic channel whether to allow to use competitive resource.
Wherein, " whether the upstream data of up logic channel 1 allows to use competitive resource " this configuration information can directly carry by configuration signal, and thus, UE MAC layer obtains this configuration information.Can be also the UE rrc layer when up logic channel is set up, send to the form of UE MAC layer with interlayer primitive, indicate the upstream data of logic channel 1 whether to allow to use competitive resource with this.
certainly, the present embodiment is the explanation of carrying out as example take up logic channel 1, for whole transmitting uplink data process, network side is when carrying out up logic channel configuration, can be configured for each up logic channel, for example, collocating uplink logic channel 1 allows or does not allow to use competitive resource for the upstream data of this up logic channel, collocating uplink logic channel 2 allows or does not allow to use competitive resource for the upstream data of this up logic channel, collocating uplink logic channel 3 allows or does not allow to use competitive resource for the upstream data of this up logic channel.
Step 102: when satisfying basic competitive resource service condition, when needing to use competitive resource, UE side MAC layer is according to the up logic channel 1 under the upstream data that arrives, the upstream data that is configured to this up logic channel allows to use competitive resource, obtains the available competition Grants nearest apart from the current time.
Wherein, because upstream data arrives or up higher priority data arrive and triggered BSR (BufferStatus Report, reporting cached state), further owing to there is no ascending resource, triggered SR, can think and satisfy basic competitive resource service condition this moment, need to use competitive resource.After determining to need the use competitive resource, obtain competition Grants, trigger the transmission of using competitive resource.
The upstream data of step 103:UE side MAC layer up logic channel 1 of transmission on competition Grants.
This step can also be, after UE MAC layer obtains competition Grants, whether again judge has the upstream data of the up logic channel that does not allow to use competitive resource to need to send this moment, for example there is the upstream data (upstream data of up logic channel 2 does not allow to use competitive resource) of up logic channel 2 to send on competition Grants, abandons the use of this competition Grants; If there is no (upstream data of supposing up logic channel 2 allow to use competitive resource), the up logic channel 1 of transmission, 2,3 upstream data on competition Grants.Suppose that namely whole logic channel 1,2,3 all is configured to respectively the upstream data permission use competitive resource of this up logic channel, do not allow to use this moment the upstream data of the up logic channel of competitive resource to need transmission, can transmit the upstream data of each up logic channel on the competitive resource of therefore authorizing.
wherein the process of transmit ascending data can be on competition Grants, UE MAC layer is according to competition Grants indication, by carrying out HARQ entity and process operation, carry out the uplink transmission data tissue, then for the upstream data that can transmit on competitive resource and MAC Control Element such as BSR (the Buffer Status Report that need to carry, Buffer Status Report), C-RNTI (CellRadioNetworkTemporaryIdentifier, cell-radio network temporary identifier) etc., complete multiplexing and PDU (the protoco1 data unit of data, protocol Data Unit) generate, the MACPDU that generates is sent on this competition Grants.
Can be found out by the present embodiment, as long as the data that do not allow to use competitive resource are arranged, this UE does not just allow to use competitive resource, only has when satisfying basic competitive resource service condition, obtain competition Grants this moment, and transmit the data that allow to use competitive resource on this competition Grants.
Second embodiment of the invention is a kind of uplink data transmission method based on competition, comprises as shown in Figure 4:
Step 201: network side sends configuration signal to UE when carrying out up logic channel channel configuration, be configured for up logic channel 1,2, indicates up logic channel 1,2 upstream data whether to allow to use competitive resource.
Certainly, also can use the UE rrc layer to inform alternately the mode of UE MAC layer by interlayer.
Step 202: when satisfying basic competitive resource service condition, when needing to use competitive resource, the upstream data that is configured to this up logic channel due to logic channel 1 does not allow to use competitive resource, and UE can not trigger the process of using the competitive resource transmission.
In this step, identical with last embodiment, trigger BSR because the data of logic channel 1 arrive, further owing to there is no ascending resource, triggered SR, namely think and satisfy basic competitive resource service condition this moment, need to use competitive resource, after determining to need the use competitive resource, the upstream data that is configured to this up logic channel due to logic channel 1 does not allow to use competitive resource, can not obtain competition Grants, just not trigger the transmission of using competitive resource yet.
Step 203: the upstream data of logic channel 2 arrives, and do not satisfy basic competitive resource service condition this moment, can not trigger the transmission of using competitive resource.
Wherein, the data due to the logic channel 1 that higher priority is arranged in buffer memory do not satisfy the BSR trigger condition, can not trigger SR yet, therefore do not satisfy basic competitive resource service condition this moment.Allow to use competitive resource even logic channel 2 is configured to the upstream data of this up logic channel, UE can not trigger the transmission of using competitive resource.
Third embodiment of the invention is a kind of uplink data transmission method based on competition, comprises as shown in Figure 5:
Step 301: network side sends configuration signal to UE when carrying out up logic channel channel configuration, be configured for up logic channel 1, indicates the upstream data of up logic channel 1 whether to allow to use competitive resource.
Certainly, also can use the UE rrc layer to inform alternately the mode of UE MAC layer by interlayer.
Step 302: when needs used competitive resource, UE MAC layer directly obtained the competitive resource of mandate.
At this moment whether the UE side MAC layer upstream data of not distinguishing logic channel 1 allows to use competitive resource, do not allow to use competitive resource even logic channel 1 is configured to the upstream data of this up logic channel, UE still obtains the available competition Grants nearest apart from the current time.
Step 303: when satisfying basic competitive resource service condition, when needing to use competitive resource, the upstream data that is configured to this up logic channel due to up logic channel 1 does not allow to use competitive resource, the upstream data of forbidding up logic channel 1 transmits on competition Grants, will transmit on competition Grants as the MAC Control Element of control information.
The upstream data that is configured to this up logic channel due to logic channel 1 does not allow to use competitive resource, there is no the upstream data that can transmit this moment on competitive resource, only comprise the MAC Control Element as control information in MAC PDU, the MAC PDU that generates is sent on this competition Grants.
Fourth embodiment of the invention is a kind of uplink data transmission method based on competition, comprises as shown in Figure 6:

Certainly, also can use the UE rrc layer to inform alternately the mode of UE MAC layer by interlayer.
Step 402: when needs used competitive resource, UE MAC layer directly obtained competition Grants.
At this moment whether the UE side MAC layer upstream data of not distinguishing logic channel 1 allows to use competitive resource, do not allow to use competitive resource even logic channel 1 is configured to the upstream data of this up logic channel, UE still obtains the available competition Grants nearest apart from the current time.
Step 403: after obtaining competition Grants, judge again, the upstream data whether up logic channel 1 is configured to this up logic channel allows to use competitive resource, if transmit the upstream data of up logic channel 1 on competition Grants, otherwise abandons competing the use of Grants.
Be that after obtaining competition Grants, the upstream data of up logic channel 1 needs transmission in this step, judge again this moment.The upstream data of same up logic channel 2 needs transmission, and the upstream data that up logic channel 2 is configured to this up logic channel allows to use competitive resource, the upstream data of the up logic channel 2 of transmission on competition Grants.
This step can be also, after obtaining competition Grants, carry out again the upstream data whether decision logic channel 1 be configured to this up logic channel and do not allow to use competitive resource, if abandon competing the use of Grants, otherwise on competition Grants the upstream data of transmission logic channel 1.
Transmit ascending data on competition Grants, mode that specifically can be as in the previous, carry out HARQ entity and process operation, for the user data that can transmit on competitive resource and MAC Control Element such as BSR, the C-RNTI etc. that need to carry, multiplexing and the PDU that completes data generates, and the MAC PDU that generates is sent on this competition Grants.
Fifth embodiment of the invention is a kind of uplink data transmission method based on competition, comprises as shown in Figure 7:
Step 501: network side sends configuration signal to UE when carrying out up logic channel channel configuration, be configured for whole up logic channels, indicates the upstream data of all up logic channels whether to allow to use competitive resource.
Certainly, also can use the UE rrc layer to inform alternately the mode of UE MAC layer by interlayer.
For example, whole up logic channels are up logic channel 1, up logic channel 2 and up logic channel 3, the configuration information indication, and whether the upstream data of logic channel 1, up logic channel 2 and up logic channel 3 all allows to use competitive resource.
Step 502: allow to use competitive resource according to the upstream data of the whole up logic channels of UE, when needs used competitive resource, UE MAC layer directly transmitted the upstream data of current up logic channel on competition Grants.
No longer distinguish in this step, the upstream data that current up logic channel is configured to this up logic channel allows to use competitive resource, or does not allow to use competitive resource.
Certainly, if not the upstream data of whole up logic channels allows to use competitive resource, when needs used competitive resource, UE MAC layer did not trigger the transmission of using competitive resource.
Transmit ascending data on competition Grants, mode that specifically can be as in the previous, carry out HARQ entity and process operation, for the user data that can transmit on competitive resource and MAC Control Element such as BSR, the C-RNTI etc. that need to carry, multiplexing and the PDU that completes data generates, and the MAC PDU that generates is sent on this competition Grants.
The scheme difference of this programme and front is, the present embodiment is the whole up logic channel for UE in when configuration, when the upstream data of the whole up logic channels of UE allows to use competitive resource, according to this configuration information, UE MAC layer directly transmits upstream data on competition Grants.
Sixth embodiment of the invention is a kind of uplink data transmission method based on competition, comprises as shown in Figure 8:
Step 601: network side is when carrying out up logic channel channel configuration, send configuration signal to UE, be configured for up logic channel 1, indicate the upstream data of up logic channel 1 whether to allow to use competitive resource, and carry the restriction thresholding to the upstream data size in configuration signal.
Step 602: when needs use competitive resource, if the upstream data of up logic channel 1 allows to use competitive resource and upstream data size to be less than or equal to predetermined restriction thresholding, or can transmit on nearest competition Grants, or can transmit on the competition Grants in 2 TTI, transmit the upstream data of up logic channel 1 on competition Grants.
Wherein, if the upstream data of up logic channel 1 allow to use competitive resource, the upstream data size is greater than predetermined restriction thresholding, or can not transmit on nearest competition Grants, or can not transmit on the competition Grants in 2 TTI, abandon the use of this competition Grants.
Certainly, 2 TTI are the preferred version of the present embodiment, can set according to the situation of reality the quantity N of TTI, and this parameter can be also network side configuration or pre-specified.In this step, upstream data can be the AM data.

Seventh embodiment of the invention is a kind of uplink data transmission method based on competition, comprises as shown in Figure 9:
The indication information that step 701:UE RLC and/or PDCP send to UE MAC layer indicates the upstream data of this up logic channel whether to allow to use competitive resource for up logic channel 1.
Wherein, UE RLC and/or PDCP with the mutual data b uffer information of MAC layer in increase the 1bit indication, whether the upstream data that is used to indicate up logic channel 1 allows to use the competition transmission, the acquisition of this information can come from the network side configuration, also can predefine principle simple according to some, allow as the AM data, UM and TM data do not allow etc.
Step 702: when needs use competitive resource, if the upstream data of up logic channel 1 allows to use competitive resource and upstream data size to be less than or equal to predetermined restriction thresholding, or can transmit on nearest competition Grants, or can transmit on the competition Grants in 2 TTI, compete the upstream data of the up logic channel 1 of the upper transmission of Grants.
Wherein, if the upstream data of up logic channel 1 allow to use competitive resource, and the upstream data size is greater than predetermined restriction thresholding, or can not transmit on nearest competition Grants, or can not transmit on the competition Grants in 2 TTI, abandon the use of this competition Grants.
As different from Example 6, due to the mode that has adopted UE RLC and/or PDCP to the indication information of UE MAC layer transmission, the size of data that arrives in up logic channel 1 can give the MAC layer by PDCP or RLC and indicate separately.When for example using competition Grants to carry out transmitting uplink data, only need the RLC SDU of first arrival of transmission, PDCP or RLC only indicate the RLC SDU size of first arrival.
When RLC packages at up logic channel 1 upstream data that needs is used competition Grants transmission, Service Data Unit SDU is not carried out staged operation or SDU quantity less than 3, same 3 preferred versions that SDU is the present embodiment, can set according to the situation of reality the quantity M of SDU, this parameter can be network side configuration or pre-specified, and wherein the upstream data at rlc layer is SDU.
