Technical solution of the present invention is further described in detail with reference to the accompanying drawings and specific embodiments of the specification.

The embodiment of the present invention provides a kind of ascending transmission method, is applied to base station, and Fig. 1 is provided by one embodiment of the invention Ascending transmission method flow diagram, as shown in Figure 1, the ascending transmission method the following steps are included:

Step 101: receiving the access request that terminal is sent by PRACH.

Specifically, referring to FIG. 2, Fig. 2 is the timing diagram for the uplink synchronisation method that one embodiment of the invention provides, such as Fig. 2 It is shown, after terminal powers on, cell selection is carried out, persistent district down channel quality is measured, determines covering grade, and corresponding Random access code Preamble is sent in PRACH resource, terminal sends Preamble as access to the base station by PRACH Request.The step 101: receiving the access request that terminal is sent by PRACH, can be base station reception terminal and passes through PRACH The Preamble of transmission.

It should be noted that due to channel resource interference or delay the problems such as, it is possible that terminal send one Base station receives the case where access request failure after Preamble, for example, terminal is after sending a Preamble, base station is simultaneously It is not detected in PRACH, does not also just receive the Preamble, be judged as that base station receives access request failure at this time；Or Base station has received send TA and upstream format to terminal after the Preamble during, terminal is not received by these information again When can also regard as base station receive access request failure.As long as base station does not confirm that the terminal is successfully accessed, which will be The time cycle of setting retransmits Preamble in PRACH；In the embodiment of the present application, base station confirm the terminal access at Function, when referring to that base station receives the terminal according to message is successfully accessed by up channel return after the TA, then base station confirmation should Terminal is successfully accessed.

Step 102: being based on the access request, send TA to terminal and carry out uplink synchronous.

Base station receives the access request of terminal transmission, sends TA to terminal and carries out uplink synchronous, that is to say, that base station connects After the access request for receiving terminal transmission, sends TA and give the terminal, can then be adjusted according to TA value after so that the terminal is received TA The time of signal transmission, to realize the uplink synchronous between the terminal and base station.

In an alternative embodiment, step 102 may include: the Preamble sent in PRACH based on terminal, Base station issues in PDCCH issues TA to terminal in upstream format information and PDSCH；The terminal is received according to the uplink lattice Formula information determines the PDSCH, the TA is obtained from the PDSCH after return be successfully accessed message, returned according to the terminal The message that is successfully accessed returned carries out uplink synchronous.

Here, base station issues upstream format information in PDCCH, wherein carries downlink in the upstream format information The resource allocation information of transmission channel, that is to say, that the PDSCH for issuing TA to terminal is carried in upstream format information Location information.Specifically, the base station issues upstream format information in PDCCH and issues TA in PDSCH to terminal, makes institute State terminal according to the upstream format information determine for issue the PDSCH of TA position, from the PDSCH obtain described in It is returned after TA and is successfully accessed message, base station receives the message that is successfully accessed of terminal return, and according to terminal return It is successfully accessed message and carries out uplink synchronous.Specifically, base station, which is issued in PDCCH in upstream format information and PDSCH, issues TA To terminal, after terminal physical layer obtains the upstream format information in PDCCH by way of blind examination, to the upstream format information It is decoded the position so that it is determined that PDSCH, finally obtains TA from PDSCH again, in the present embodiment, terminal is led to after obtaining TA Cross PUSCH return be successfully accessed message give base station carry out uplink synchronous.In other embodiments, terminal can also lead to after obtaining TA Other up channels are crossed, carry out uplink synchronous to base station as PUCCH return is successfully accessed message.Finally, base station connects receiving this Confirmation uplink synchronous is successful after entering success message, is successfully accessed in other words.

In an optional specific embodiment, with continued reference to FIG. 2, uplink synchronisation method includes the following steps: terminal When access base station, by sending Preamble in PRACH resource as access request；Base station is based on the access request, It is issued in PDCCH and issues TA in upstream format information and PDSCH to terminal；Terminal is decoded according to TA reception condition and base station PDSCH situation decides whether to retransmit PRACH to base station；Terminal is determined according to upstream format information where the PDSCH for carrying TA Position and after getting TA in PDSCH return be successfully accessed message；Base station is carried out according to the message that is successfully accessed that terminal returns Uplink synchronous.

Wherein, terminal decides whether to retransmit PRACH according to TA reception condition and base station decoding PDSCH situation, actually Refer to, due to channel resource interference or delay the problems such as presence, it is possible that terminal send Preamble it Base station receives the case where access request failure afterwards, or when base station issues upstream format or TA the case where terminal reception failure, Or the case where failing when base station decodes etc., that is to say, that as long as base station does not confirm that the terminal is successfully accessed, the terminal Preamble can be retransmitted in PRACH in the time cycle of setting；And in the present embodiment, base station confirm the terminal access at Function refers to that base station receives the terminal and just can confirm that the terminal is successfully accessed when being successfully accessed message according to what the TA was returned.

Step 103: when uplink synchronous is completed, sending configuration parameter to the terminal, match the terminal according to Set the uplink channel transmission upstream data of parameter configuration, the up channel of the configuration parameter configuration includes continuously arranged exempting to adjust Spend PUSCH.

Here, the uplink synchronous is completed, main to include two kinds and synchronously complete condition: first, when receiving the terminal hair When being successfully accessed message of the predetermined quantity sent, uplink synchronous are completed.Wherein, predetermined quantity can be according to connecting with the base station Terminal quantity determines, for example, using base station with connect the terminal of the base station as a system, it is assumed that have ten ends in the system End, then the predetermined quantity can be ten, be also possible to nine or other quantity, when the terminal of predetermined quantity is ten When, each terminal will all send access request, and base station sends uplink after being respectively received the access request that each terminal is sent Format and TA give corresponding terminal, then each terminal returned after the upstream format and TA for receiving base station transmission an access at At this moment function message determines that uplink synchronous is completed.That is, only base station receive ten be successfully accessed message after, just will not It goes in PRACH to detect whether that there are access request codes again, is at this moment then judged as that uplink synchronous is completed；Second, it is described when receiving At least the one of terminal transmission is successfully accessed message, and is arranged in the time and is not detected what the terminal was sent in the PRACH When Preamble, uplink synchronous is completed.Wherein, the setting time can be the period that terminal sends access request, naturally it is also possible to It is greater than the other time that terminal sends the period of access request, is so that time as the period that terminal sends access request is arranged Terminal hair is not detected in example, base station within the time that terminal sends a cycle of access request in all PRACH resources At this moment the Preamble sent is then judged as that uplink synchronous is completed it can be said that bright all terminals have been successfully accessed.It needs to illustrate , terminal receive TA success after feedback one be successfully accessed message after then no longer to base station by PRACH transmission Preamble。

Here, configuration parameter includes uplink channel resources distributed intelligence；It is described when uplink synchronous complete when, base station send matches Parameter is set to terminal, so that the uplink channel transmission upstream data that the terminal is configured according to the configuration parameter.It is optional at one Embodiment in, when uplink synchronous complete when, base station send configuration parameter to terminal so that the terminal is according to the configuration parameter The uplink channel transmission upstream data of configuration specifically includes: when uplink synchronous is completed, sending uplink channel resources distributed intelligence To the terminal, so that the terminal exempts from dispatching uplink channel logo according to first in the uplink channel resources distributed intelligence The sustained continuous arrangement that information, the first dot position information determine exempts to dispatch PUSCH transmission upstream data；In another optional reality It applies in example, when uplink synchronous is completed, base station sends configuration parameter to terminal, so that the terminal is configured according to the configuration parameter Uplink channel transmission upstream data specifically include: when uplink synchronous complete when, send uplink channel resources distributed intelligence to institute Terminal is stated, is believed so that the terminal exempts from dispatching uplink channel logo according to second in the uplink channel resources distributed intelligence The periodically continued arrangement that breath, the second start position information and cycle information determine exempts to dispatch PUSCH transmission upstream data.
