Embodiment

To make the technical problem to be solved in the present invention, technical scheme and advantage clearer, below in conjunction with attached Figure and specific embodiment are described in detail.

First embodiment

As shown in figure 3, a kind of method of Stochastic accessing of first embodiment of the invention, including：

Step 301, at least one TRP sent in receiving node TRP groups sends down-going synchronous to terminal Signal and the system information for sending the TRP groups where the TRP；Wherein, the system information carries There is random access resource information；

Step 302, the Stochastic accessing that the terminal carries in the system information of its resident TRP group is received The lead code sent on the random access resource of resource information instruction；Wherein, the resident TRP of the terminal Group is that terminal selects according to the downlink synchronous signal of its TRP group received；

Step 303, in the TRP groups that the terminal is resident, the down-going synchronous letter has been transmitted across it Number and the system information target TRP, according to the lead code, feed back the TRP to the terminal The Stochastic accessing response of group.

In the embodiment of the present invention, at least one TRP can send downlink synchronous signal and the TRP to terminal Random access resource configuration is carried in the system information of the TRP groups at place, the wherein system information.From And terminal is being received downlink synchronous signal, can be resident according to the downlink synchronous signal selection received should TRP groups (TRP groups have its corresponding TRP group address ID), and select the resident TRP groups in terminal The system information of the TRP groups is obtained afterwards, it is random at this according to the random access resource information wherein carried Lead code is sent on the random access resource of access-in resource information instruction.

Then, at least one TRP of the TRP groups can just be received on corresponding random access resource The lead code that the terminal is sent.

Afterwards, the downlink synchronous signal and the target of the system information are transmitted across in the TRP groups TRP, according to the lead code, the Stochastic accessing response of the TRP groups is fed back to terminal.

So, terminal just has access in network the TRP groups for comprising at least a TRP, and realization exists respectively On different sub-band in access website bandwidth of operation or website send different beams side work up, meet GSM needs broader message transmission rate, supports more terminal accesses, ensures lower net Network time delay and the demand that more rich type of service is provided.

Wherein, step 301 includes：

Step 3011, under at least one TRP for being operated in low-frequency range in the TRP groups is sent to terminal The system information of line synchronising signal and the TRP groups.

It can thus be appreciated that the part TRP in TRP groups is operated in low-frequency range, part TRP is operated in high band. Certainly, also can sends downlink synchronous signal and the TRP groups from being operated in low-frequency range TRP to terminal System information, or send downlink synchronous signal and the TRP to terminal from being operated in high band TRP The system information of group.

In embodiments of the present invention, system information (such as host system message block MIB and the system letter of TRP groups Breath block SIB-X) it is for all TRP in TRP groups region (SIA, System Information Area) All effective configuration information, can by TRP groups at least one TRP (such as one, it is multiple or all TRP) send, can be by least one TRP for being operated in low-frequency range or at least one in TRP groups The TRP for being operated in high band is sent.

And downlink synchronous signal, it can be single-stage or multistage, be sent by the TRP of transmission system information Downlink synchronous signal, to cause terminal to select resident TRP groups according to down-going synchronous information.With under two level Exemplified by line synchronising signal, terminal can detect one or more downlink synchronous signal 1 and downlink synchronous signal 2 (sync1/2), and when detecting the sync1/2 of corresponding multiple TRP groups, it is contemplated that the matter of reception signal Amount, TRP groups are resident corresponding to the sync1/2 of selection signal maximum intensity.

In addition, in the embodiment of the present invention, each TRP in TRP groups has corresponding ID, each TRP Can also have specific physical layer configurations, such as subcarrier spacing, bandwidth etc..Certainly, each TRP Can also have corresponding synchronizing information and its own system information.Idle IDLE terminal may reside within In TRP groups, IDLE terminal need not identify TRP before Stochastic accessing.

Further, all TRP in the TRP groups are synchronous, but wherein at least one TRP is sent out Send downlink synchronous signal and system information；Or the part TRP in the TRP groups is synchronous.

In addition, step 302 includes：

Step 3021, at least one TRP in the TRP groups receives the terminal in its resident TRP The lead code sent on the random access resource carried in the system information of group.

So, system information of at least one TRP receiving terminals in TRP groups in its resident TRP group After the lead code sent on the random access resource of middle carrying, the target TRP in the TRP groups can be to end Feed back the Stochastic accessing response of the TRP groups in end.

Wherein, in step 303, the Stochastic accessing response of the TRP groups is fed back to the terminal Step includes：

Step 3031, the Stochastic accessing response message according to caused by the lead code that the target TRP is received, And/or the downlink synchronous signal and the system information are not transmitted across in the TRP groups but is received Stochastic accessing response message caused by the other TRP for the lead code that terminal is sent, obtains the TRP groups Stochastic accessing response, and feed back the random of the TRP groups to the terminal from the target TRP and connect Enter response.

Downlink synchronous signal and system information, i.e. TRP are sent because the TRP in TRP groups differs to establish a capital TRP in group differs, and to establish a capital be target TRP, therefore such as step 3031, it is necessary to first be connect according to target TRP It is not transmitted across in Stochastic accessing response message caused by the lead code received, and/or the TRP groups descending same Walk signal and system information but receive Stochastic accessing caused by other TRP of the lead code of terminal transmission Response message so that target TRP obtains the Stochastic accessing response of the TRP groups, then again by target TRP feeds back the Stochastic accessing response of the TRP groups to the terminal.

Specifically, in step 3031, connect at random according to caused by the lead code that the target TRP is received The step of entering response message, obtaining the Stochastic accessing response of the TRP groups includes：

Step 3031a, in the TRP groups, if only described target TRP receives terminal transmission Lead code, then the Stochastic accessing responses of the TRP groups is produced by the target TRP.

Here, due to being only that the target TRP for the Stochastic accessing response for feeding back the TRP groups to terminal connects The lead code received, now, so that it may which the Stochastic accessing that the TRP groups are directly produced by target TRP should Answer response.

However, often TRP groups include multiple TRP, and the terminal of lead code is sent to the TRP groups One is not limited only to, often to be multiple, so, further step 3031a includes：

Step 3031a1, in the TRP groups, if multiple target TRP are respectively received terminal hair The lead code sent, then multiple target TRP be exchanged with each other each caused by Stochastic accessing response message, obtain The Stochastic accessing response of the TRP groups.

In the case of multiple target TRP in TRP groups are respectively received the lead code of terminal transmission, with one Exemplified by the individual target TRP for receiving lead code, although can produce it is corresponding its receive it is at least one before The Stochastic accessing response message of leading code, but target TRP can not determine its caused Stochastic accessing response Information corresponded to the oriented TRP groups send the terminal of lead code, therefore, in the TRP groups, such as walk Rapid 3031a1, multiple target TRP are exchanged with each other each caused Stochastic accessing response message, obtain the TRP The Stochastic accessing response of group.So, the Stochastic accessing response for the TRP groups that target TRP is obtained rings It should can just include complete Stochastic accessing response message, and feed back to TRP group targets TRP receptions Terminal corresponding to the lead code arrived.

Wherein, being exchanged with each other for the Stochastic accessing response between target TRP can be, but not limited to pass through Back haul link between TRP is realized.

Specifically, in step 3031, the downlink synchronous signal is not transmitted across according in the TRP groups And the system information but receive terminal transmission lead code other TRP caused by Stochastic accessing should The step of answering information, obtaining the Stochastic accessing response of the TRP groups includes：

Step 3031b, in the TRP groups, if before other TRP receive terminal transmission Leading code, then as caused by being sent the other TRP Stochastic accessing response message to the target TRP, institute Target TRP is stated according to the Stochastic accessing response message, the Stochastic accessing response for obtaining the TRP groups rings Should.

Here, other TRP receive the lead code of terminal transmission, corresponding to other TRP generations After Stochastic accessing response message, because other TRP can not feed back the Stochastic accessing of the TRP groups to terminal Response, so, such as step 3031b, it is necessary to Stochastic accessing response caused by other TRP are first sent Information is to target TRP, then from that can feed back the Stochastic accessing responses of the TRP groups to terminal The Stochastic accessing response that target TRP obtains TRP groups according to the Stochastic accessing response message received rings Should.

Wherein, other TRP send caused by Stochastic accessing response message to target TRP specific implementation bag Include but be not limited to other TRP and its caused Stochastic accessing response is sent by the back haul link between TRP Information is to target TRP.

Certainly, there are the feelings for the lead code for receiving terminal transmission for multiple target TRP and other TRP Condition, after Stochastic accessing response message caused by other TRP transmissions to target TRP, multiple target TRP Between also need to be exchanged with each other each caused by Stochastic accessing response message, so as to which target TRP can be obtained Include the Stochastic accessing response of complete Stochastic accessing response message, and be fed back to terminal.

After the Stochastic accessing response of the TRP groups is obtained, specifically, in step 303, to described The step of Stochastic accessing response of the terminal feedback TRP groups, includes：

Step 3032, sent using with sending the downlink synchronous signal and the system information identical Mode, the Stochastic accessing response of the TRP groups is fed back to the terminal.

So, terminal just can be attempted to receive in the bandwidth for receiving downlink synchronous signal and system information The Stochastic accessing response of TRP groups.

Understand, in embodiments of the present invention, downlink synchronous signal and the TRP groups are transmitted across in TRP groups The target TRP of system information can realize：Detection receives eventually on the random access resource of the TRP groups Hold the lead code sent；Receive be not transmitted across in the TRP groups downlink synchronous signal and system information but Stochastic accessing response message caused by other TRP of the lead code of terminal transmission is received, such as by returning Journey link；Include multiple target TRP in the TRP groups, Stochastic accessing response is exchanged between target TRP Information, such as exchanged by back haul link；The lead code received according to detection and other TRP notices Stochastic accessing response message, send the Stochastic accessing responses of the TRP groups.

In embodiments of the present invention, downlink synchronous signal and the TRP groups are not transmitted across in TRP groups The TRP of system information can be realized：Receiving terminal is detected on the random access resource of the TRP groups to send Lead code；When detection on the random access resource of the TRP groups receives the lead code of terminal transmission, Target TRP its Stochastic accessing response message in the TRP groups is notified, such as passes through back haul link.In addition, The TRP for not being transmitted across downlink synchronous signal and the system information of the TRP groups is not to be somebody's turn to do to terminal feedback The Stochastic accessing response of TRP groups.

To sum up, the method for the Stochastic accessing of the embodiment of the present invention, the target TRP in TRP groups are sent out to terminal The system information of downlink synchronous signal and the TRP groups is sent, at least one TRP of the TRP groups just can Receiving terminal selection is resident what the random access resource information carried after the TRP groups in system information indicated The lead code sent on random access resource, then the target TRP in the TRP groups should to terminal feedback The Stochastic accessing response of TRP groups.Realize different sub-band of the terminal respectively in access website bandwidth of operation The different beams side that upper or website is sent works up, and meets that the broader data of GSM needs pass Defeated speed, more terminal accesses are supported, ensures lower network delay and more rich type of service is provided Demand.Wherein, the Stochastic accessing response for the TRP groups fed back to terminal, is according to the TRP The different situations of lead code are received in group, are obtained by different modes, there is more preferably practicality.

For the method for clearer description Stochastic accessing provided in an embodiment of the present invention, with reference to specific reality Example is applied the method for Stochastic accessing provided in an embodiment of the present invention is described in detail：

First case：

As shown in figure 4, include multiple TRP, and all TRP in the TRP groups in a TRP group It is synchronous.Because at least one TRP (target TRP) sends two level down-going synchronous letter in the TRP groups The system information of number (sync1/2) and the TRP groups.

Terminal receives downlink synchronous signal in specific resources measurement, and according to all down-going synchronous received Signal, the sync1/2 of selection signal maximum intensity as resident TRP group downlink synchronous signals, and according to The sync1/2 received determines TRP groups ID and descending sequential.

As shown in figure 4, the system information (MIB and SIB-X) of the TRP groups sent is directed to TRP groups Region (SIA) 400 all effectively, random access resource is carried in system information and (is wrapped in such as SIB-X Physical Random Access Channel PRACH resource allocation informations containing the TRP groups).

Terminal is according to TRP groups ID and descending timing acquisition to PRACH resource allocation information (the i.e. physics The configuration information of random access resource), in the PRACH resources that the PRACH resource allocation informations are specified Upper transmission lead code (preamble).

Assuming that the terminal UE 1 that selection resides in the TRP groups needs to access network, then UE1 is receiving this After the PRACH resource allocation informations that the SIB-X of the system information of TRP groups is included, provided in the PRACH Preamble is sent in the resource of source configuration information instruction.

At least one TRP in the TRP groups is detected in the PRACH resources receives UE1 transmissions preamble.After the TRP groups receive the preamble, by sending sync1/2 and the TRP groups At least one TRP of system information sends Stochastic accessing response.

When transmission sync1/2 and the system information of the TRP groups TRP have received UE1 transmissions Preamble, then Stochastic accessing response is sent according to the preamble received, and should in Stochastic accessing Answer in response and carry the preamble relevant informations received；

When the TRP for the system information that sync1/2 and the TRP groups are not transmitted across in TRP groups is received The preamble that UE1 is sent, then need Stochastic accessing the response message related preamble notifying hair The TRP of the system information of sync1/2 and the TRP groups is sent, advice method is such as notified by back haul link, Stochastic accessing response is sent by the TRP for the system information for sending sync1/2 and the TRP groups.

UE1 attempts to receive the TRP in the bandwidth of system information for receiving sync1/2 and the TRP groups The Stochastic accessing response of group.

Second case

The scene under TRP groups as described in first case, in the second case, in the TRP group coverages Multiple terminals sends different preamble in the resource that SIB-X PRACH resource allocation informations indicate. TRP in the TRP groups is detected in the PRACH resources receives preamble.

Assuming that TRP1 have received the preamble of UE3 transmissions, TRP2 have received UE2 transmissions Preamble, and TRP1 and TRP2 is that sync1/2 and the system of the TRP groups are sent in the TRP groups The TRP of information.
