Embodiment
At problems of the prior art, a kind of brand-new random access feedback messages delivery plan is proposed: among the present invention when descending member carrier number is counted greater than uplink member carrier, at first, whole downlink member carriers are divided into the M group, M is a positive integer, at each downlink member carrier group, respectively spendable whole random access sequences are divided into the N group, downlink member carrier number selected in the value of N and the downlink member carrier group is identical, makes the corresponding random access sequence group of each selected downlink member carrier; Then, on each selected downlink member carrier, send downlink synchronous signal and broadcast message, carry in the described broadcast message and corresponding random access sequence group of downlink member carrier and the spendable Random Access Channel information of terminal that should select; Afterwards, in Random Access Channel, detect the random access sequence of self terminal, and determine the random access sequence group that detected random access sequence is affiliated, on the pairing selected downlink member carrier of the random access sequence group of determining, send random access feedback messages.Compared with prior art, scheme of the present invention can utilize the random access sequence group to distinguish different downlink member carriers, thereby has avoided all sending random access feedback messages on all downlink member carriers, and then has saved the downlink member carrier resource.In actual applications, the specific actor of said process is the base station.
Here the selected downlink member carrier of being mentioned is meant that follow-up needs carry out the downlink member carrier of downlink synchronous signal and broadcast message transmission.The concrete prior art that is sent as of selecting which downlink member carrier to carry out downlink synchronous signal and broadcast message repeats no more.
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
Fig. 1 is the flow chart of random access feedback messages sending method embodiment of the present invention.For ease of describing, in the present embodiment " selected downlink member carrier " abbreviated as " downlink member carrier ".As shown in Figure 1, this embodiment may further comprise the steps:
Step 101: whole downlink member carriers are divided into the M group, and M is a positive integer; At each downlink member carrier group, respectively spendable whole random access sequences are divided into N group, the value of N is identical with downlink member carrier number in the downlink member carrier group, makes random access sequence group of each downlink member carrier correspondence.
In this step, at first, as required, whole downlink member carriers is divided into M group (the downlink member carrier number in every group is not necessarily identical); Then, at each downlink member carrier group, carry out following operation respectively: spendable whole random access sequences are divided into the N group, and the interior downlink member carrier number of the value of N and this downlink member carrier group is identical, makes random access sequence group of each downlink member carrier correspondence.
Specifically how random access sequence is divided into groups and can be decided according to the actual requirements, such as, can be with spendable whole random access sequences mean allocation on N downlink member carrier, perhaps, can be certain some random access sequence of downlink member carrier overabsorption also, and other downlink member carriers distribute some random access sequences less according to actual conditions.
For making things convenient for subsequent descriptions, the value of supposing M in the present embodiment is 1, promptly has only a downlink member carrier group, and, N downlink member carrier in this downlink member carrier group is numbered downlink member carrier 1, downlink member carrier 2 respectively ..., downlink member carrier N; Correspondingly, will be numbered random access sequence group 1 respectively with corresponding N random access sequence group of this N downlink member carrier, random access sequence group 2 ..., random access sequence group N.
Step 102: the base station sends downlink synchronous signal and broadcast message to terminal on each downlink member carrier, wherein, carry in the broadcast message and corresponding random access sequence group of this downlink member carrier and the spendable Random Access Channel information of terminal.
That is to say, to carry random access sequence group 1 in the broadcast message that is sent on the downlink member carrier 1, to carry random access sequence group 2 in the broadcast message that is sent on the downlink member carrier 2, ..., will carry random access sequence group N in the broadcast message that is sent on the downlink member carrier N.
How the base station sends downlink synchronous signal and broadcast message is a prior art to terminal, repeats no more.
Step 103: terminal reads a downlink synchronous signal and a broadcast message on the downlink member carrier, utilize downlink synchronous signal to finish synchronously, and from broadcast message, select a random access sequence in the entrained random access sequence group, send to the base station by Random Access Channel.
In this step, terminal is carried out cell initial search, promptly reads downlink synchronous signal and broadcast message on the downlink member carrier in N the downlink member carrier at random, utilize downlink synchronous signal finish and the base station between synchronously; Then, from the broadcast message that reads, select a random access sequence at random in the entrained random access sequence group, send to the base station, promptly initiate to insert at random request to the base station by Random Access Channel.
Step 104: the random access sequence that comes self terminal is detected in the base station in Random Access Channel, and determine the random access sequence group that detected random access sequence is affiliated, on the pairing downlink member carrier of determining of random access sequence group, send random access feedback messages.
In this step, after the base station detects the random access sequence of self terminal, judge which random access sequence group this random access sequence belongs to, suppose judged result for belonging to random access sequence group 1, the base station then sends random access feedback messages to terminal on downlink member carrier 1 so.In actual applications, after the base station receives random access sequence, may also need to carry out some other processing, but since irrelevant with scheme of the present invention, so be not described.
In the subsequent process, terminal (promptly reads in the downlink member carrier of broadcast message) in the corresponding downstream member carrier and monitors, to determine whether to receive random access feedback messages from the base station, if, then initiate the scheduling of resource request, otherwise, proceed to insert at random, repeat no more.
