Embodiment
Among the present invention, UE receives RAR information according to the maximum retransmission of accidental access response window and random access lead code, and wherein, in the accidental access response window, the reception of RAR information can be supported the HARQ function, also can not support the HARQ function.Perhaps, among the present invention, the maximum retransmission of accidental access response window and random access lead code need be set, but realize reception RAR information through the HARQ function.
Below in conjunction with accompanying drawing the present invention is elaborated, specifically sees also Fig. 2～Fig. 4.
Fig. 2 is the figure of access process at random that in carrier aggregation, receives RAR information provided by the invention, property ground as an example, and Cell1 is the PCell of UE, and other are the SCell of UE, are the SCell1 of UE like Cell2, and Cell3 is the SCell2 of UE.SCell1 dispatches through PCell, and SCell2 is through this carrier dispatching.Network selecting UE inserts on Cell2 (being the SCell1 of UE) at random.
As shown in Figure 2, this flow process comprises:
Step 201, base station (eNB) is that UE distributes random access lead code through Msg0 message, particularly, eNB through sub-district 1, be that the dispatching cell PCell of the SCell1 of UE sends Msg0 message to UE.
Step 202, UE is to sub-district 2, promptly Msg1 message is sent in auxilliary sub-district 1, thus the transmitting random access preamble sign indicating number.
Step 203, network sends the PDCCH with the C-RNTI scrambling through auxilliary sub-district 2 to UE, should indicate the transfer resource of Msg2 message with the PDCCH of C-RNTI scrambling.
Step 204, UE receives Msg2 message on the transfer resource that the PDCCH with the C-RNTI scrambling indicates, from Msg2 message, read the RAR information that comprises the TA value.
Fig. 3 is the first pass figure of reception RAR information provided by the invention.
In flow process shown in Figure 3, the HARQ function is not supported in the reception of RAR information, and RAR information can be transmitted with the regular traffic data multiplex, the regular traffic data multiplex of also can getting along well transmits.Because the time that the regular traffic data do not limit reception is so flow process shown in Figure 3 proposes to adopt the mechanism of accidental access response window to carry out the reception of RAR information.
As shown in Figure 3, this flow process specifically comprises:
Step 301, UE monitors the PDCCH with the C-RNTI scrambling in the accidental access response window.
Wherein, Because the system information of SCell is indicated to UE through dedicated signaling RRC connection reconfiguration message in the carrier aggregation scene; Therefore; The configuration information of accidental access response window can obtain through the mode that shows, promptly connects the configuration information that obtains the accidental access response window of auxilliary sub-district (SCell) the reconfiguration message from Radio Resource control (RRC).
Because what UE carried out on SCell is that non-competitive mode inserts at random; In order to save the expense of signaling; The configuration information of accidental access response window also can obtain through the mode of implicit expression; Promptly obtain the accidental access response window configuration information of main plot (PCell), the accidental access response window of sharing PCell carries out the reception of the RAR information of SCell.
Step 302, UE judges in said accidental access response window, whether to listen to the PDCCH with the C-RNTI scrambling, if, execution in step 303, otherwise, execution in step 311.
Step 303, UE receives the downlink data with the transmitted over resources of CRNTI scrambling PDCCH indication in said accidental access response window.
Step 304, UE judges in said accidental access response window, on the resource with the PDCCH indication of C-RNTI scrambling, whether receives downlink data, if, execution in step 305, otherwise, execution in step 311.
Step 305, UE decodes to the downlink data that receives.
Step 306, UE judges whether decoding is successful, if, execution in step 307, otherwise, execution in step 310.
Step 307, UE judges whether the downlink data that receives comprises RAR information, if, execution in step 308, otherwise, execution in step 309.
Step 308; UE is to the downlink data that includes only RAR information feeding back ACK message not then; To RAR information and the multiplexing then feeding back ACK of business datum message; Promptly comprise RAR information and downlink service data at decoded result, or when only comprising downlink service data, UE feeding back ACK message, process ends.
Step 309, UE feeding back ACK message is returned step 301.
Wherein,, makes and do not support HARQ, and the transmission of business datum is when supporting HARQ that RAR information and business datum still can multiplexing transmission in the RAR transmission of Information through step 308～309.
Step 310, UE does not feed back NACK message.
In this step, UE need monitor the PDCCH with the C-RNTI scrambling in the accidental access response window.And in the downlink data transmission process, with the downlink data transmission of the PDCCH of C-RNTI scrambling indication, what possibly transmit is downlink service data; Also possibly be RAR information, downlink service data wherein need be supported the HARQ function, and RAR information is not supported the HARQ function; If decoding error, then can't to distinguish be that the downlink data that receives is downlink service data or RAR information to UE, therefore can't confirm whether should feed back NACK message; The solution that proposes among the present invention is, if UE receives the downlink data with C-RNTI scrambling PDCCH indication in the accidental access response window, if decoding error; Then do not send the NACK feedback, the reasons are as follows:
If what this moment, network side sent is downlink service data; Then network side is not received the HARQ feedback according to timing relationship in the specific moment; Promptly both confiscated ACK message and also confiscated NACK message, then network side will carry out the re-transmission of downlink service data according to existing mechanism, in other words; When network side does not reach maximum retransmission at the number of retransmissions of said downlink service data, retransmit said downlink service data.
If what this moment, network sent is RAR information, then UE does not also correctly receive RAR information this moment, therefore after the accidental access response window finishes; To get into step 311; Promptly when the transmission of random access lead code did not reach maximum, UE carried out the transmission of lead code again, after network side receives the random access lead code of UE transmission; Can in next accidental access response window, send PDCCH with the C-RNTI scrambling to UE; In order to indication RAR transmission of Information resource, and on said transfer resource, send RAR information, so that UE receives RAR information on this transfer resource to UE.
Step 311, UE judges that random access lead code sends number of times and whether reaches maximum, if UE finishes this random access procedure, otherwise, execution in step 312.
Step 312, UE sends random access lead code to network side again, returns step 301.
In the method shown in Figure 3,, getting at random outside the response window because the RAR transmission of Information can only be carried out in the accidental access response window; What transmit is normal business datum, and therefore, UE at said accidental access response outside window; Downlink data receiving on the resource that the PDCCH with the C-RNTI scrambling indicates is decoded to the downlink data that receives, when decoding successfully; Feeding back ACK message, when the decoding failure, feedback NACK message.
Fig. 4 is second flow chart of reception RAR information provided by the invention.
In the flow process shown in Figure 4, still in the accidental access response window, receive RAR information, different with flow process shown in Figure 3 is that in the accidental access response window, the HARQ function is supported in the reception of RAR information.
No matter which kind of form is the RAR information among the present invention adopt, and all is regular length generally, adds the longest 56bits of being of MAC head.Therefore; If the HARQ function is supported in the reception of RAR information, cause the waste that loads too many filling (padding) bit and cause resource for fear of RAR information of single-shot, therefore; Under the situation that resource allows, RAR information can with the business datum multiplexing transmission.
As shown in Figure 4, this flow process comprises:
Step 401, UE monitors the PDCCH with the C-RNTI scrambling in the accidental access response window.
In this step, the acquisition of accidental access response window configuration information can not given unnecessary details referring to the associated description of step 301 here.
Step 402, UE judges in the accidental access response window, whether to listen to the PDCCH with the C-RNTI scrambling, if, execution in step 403, otherwise, execution in step 414.
Step 403, UE in the accidental access response window, on transfer resource with C-RNTI scrambling PDCCH indication, downlink data receiving.
Step 404, UE judges in said accidental access response window, whether to receive said downlink data, if, execution in step 405, otherwise, execution in step 414.
Step 405, UE decodes to the downlink data that receives.
Step 406, UE judges whether decoding is successful, if, execution in step 407 and step 408, otherwise, execution in step 409.
Step 407, UE judges whether comprise RAR information in the decoded result, if process ends is if not, return step 401.
Step 408, UE is to network side feeding back ACK message.
Step 409, UE is to network side feedback NACK message.
Step 410, network side and UE side judge whether the accidental access response window finishes, if, execution in step 414, otherwise, execution in step 401 and 411.
Step 411, network side judge whether the number of retransmissions of RAR information in said accidental access response window has reached maximum retransmission, if, execution in step 412, otherwise, execution in step 413.
Step 412, network side do not retransmit RAR information, return step 401,
Step 413, network side retransmits RAR information, returns step 401.
Wherein, In step 411～413; Network side confirms according to timing relationship whether the NACK message that in the accidental access response window, receives is to be directed against RAR information, if; The RAR information number of retransmissions of network side in said accidental access response window do not reach maximum and said accidental access response window when not finishing; Network side retransmits said RAR information, if the RAR information number of retransmissions in the accidental access response window has reached maximum, then network side stops at and retransmits said RAR information in the said accidental access response window.
Step 414, UE judges whether the transmission number of times of random access lead code has reached maximum, if, process ends, otherwise, execution in step 415.
Step 415, UE resends random access lead code, and returns step 401.
In flow process shown in Figure 4; Because the re-transmission of RAR information is accomplished in the accidental access response window; Therefore network side needs according to the RAR information number of retransmissions maximum in the accidental access response window and the retransmit interval of RAR information; Configuration accidental access response window is long, and in other words, it is long that the product of the RAR information number of retransmissions maximum in the accidental access response window and the retransmit interval of RAR information need be not more than the accidental access response window.
Fig. 5 is the 3rd flow chart of reception RAR information provided by the invention.
In the flow process shown in Figure 5, the HARQ function is supported in the reception of RAR information, and; Because the reception of RAR information can have been supported the HARQ function, network side can be according to HARQ feedback and timing relationship; Confirm whether UE correctly receives RAR information, therefore, it is long that the accidental access response window need be set; As shown in Figure 5, this flow process comprises:
Step 501, network side trigger UE and begin random access procedure.
Step 502, UE sends random access lead code to network side, network side execution in step 503～step 505, UE side execution in step 506.
Step 503, network side judge whether to receive the random access lead code of UE transmission, if, execution in step 504, otherwise, step 501 returned.
Step 504, network side sends the PDCCH with the C-RNTI scrambling to UE, in order to indication RAR transmission of Information resource.
Step 505, network side sends RAR information on the resource of C-RNTI indication.
Step 506, UE monitors the PDCCH with the C-RNTI scrambling.
Step 507, UE is downlink data receiving on the resource of indicating with C-RNTI scrambling PDCCH.
Step 508, UE judges whether to receive said downlink data, if, execution in step 509, otherwise, execution in step 514.
Step 509, UE decodes to the downlink data that receives.
Step 510, UE judges whether decoding is successful, if, execution in step 511, otherwise, execution in step 512.
Step 511, UE judges whether decoded result comprises RAR information, if, execution in step 515, otherwise, step 506 returned.
Step 512, UE feedback NACK message.
Step 513, network side judge whether the maximum retransmission of RAR information reaches maximum, if, finishing this random access procedure, network can or postpone to trigger immediately new random access procedure, otherwise, execution in step 504.
Step 514, network side is determined UE according to timing relationship and is not received RAR information, returns step 513.
Step 515, UE feeding back ACK message, process ends.
Wherein, in step 511 and the step 515, also can judge decode successfully after, whether feeding back ACK message comprises RAR information then in judging decoded result immediately, if comprise, then process ends if do not comprise, is returned step 506 again.
In the flow process shown in Figure 5, network side can judge whether said UE successfully receives RAR information according to the HARQ feedback of UE, particularly:
Network side judges whether to receive that according to timing relationship UE is directed against the ACK message or the NACK message of RAR information; When judging when receiving that UE is directed against the ACK message of RAR information; Network side judges that UE successfully receives RAR information; Receive that when judging UE is directed against the NACK message of RAR information, or does not receive that UE is directed against HARQ when feedback of RAR information, network side judges that UE does not successfully receive RAR information.
In flow process shown in Figure 5, when RAR information was can be with downlink service data multiplexing, the maximum retransmission of RAR information can be the maximum retransmission of downlink service data; When RAR information was can not be with downlink service data multiplexing, the maximum retransmission of RAR information can be disposed by network side.
