Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, those of ordinary skill in the art are obtained every other without creative efforts Embodiment shall fall within the protection scope of the present invention.

The method of the present invention embodiment one

A kind of data communications method, the mainly communication means of user equipment are provided, for example support the user of machine communication The communication means of equipment is applied in data communication system as shown in Figure 1 a or 1b, and system includes shown in Fig. 1 a First base station, BTS management unit and the second base station where in the serving cell of user equipment, second base station are the user Base station where at least one cooperation cell of equipment, wherein BTS management unit can manage first base station and each second Information of base station, such as resource scheduling information etc. can connect the communication between first base station and the second base station.And the BTS management Unit is as the equipment independently of each base station.

The system shown in Fig. 1 b includes the cooperation of the first base station and user equipment where user equipment serving cell The second base station where cell, wherein may include BTS management unit in first base station or the second base station（In Fig. 1 b One base station includes BTS management unit）, the function of the function of the BTS management unit and BTS management unit in above-mentioned Fig. 1 a It is similar, unlike, in this case, BTS management unit is as the unit in some base station.

Wherein, each user equipment has the second base station of base station and different cooperation cells where serving cell, and It is not necessarily adjacent on geographical location between two base stations and the first base station, but second base station can be shared with first base station Communication channel resources, and the uplink transmission data of stronger user equipment can be received with first base station, and user equipment is all Each second base station and the stronger downlink transmission data of first base station can be received.

The present embodiment is the method performed by the first base station where the serving cell of the user equipment, flow chart such as Fig. 1 c It is shown, including：

Step 101, determine user equipment serving cell into row data communication resource scheduling information.

It is appreciated that base station can be first the data service of current area（Such as MTC service）Configure Physical Broadcast Channel （Physical Broadcast Channel, PBCH）Information, the PBCH information may include the phase of user equipment random access Close information, such as power control information and timing synchronisation information etc.；After user equipment is completed to synchronize with the cell of first base station, In the PBCH information for listening to first base station, user equipment can initiate the flow that random access concurrently send upstream data. Wherein after user equipment initiates the request of random access, if first base station agrees to that the user equipment accesses, user equipment meeting The request of scheduling of resource is initiated, then first base station can carry out user equipment the coordination of scheduling of resource, can specifically pass through this Step 101 to 103 in embodiment is coordinated.

In the present embodiment, many factors, such as the actual data service of user equipment and money can be considered in first base station The current occupancy in source etc. is dispatching user facility resource, and resource scheduling information may include running time-frequency resource and/or frequency here The information etc. of domain resource.

Step 102, the resource scheduling information determined in step 101 is sent to the second base station, so that the second base station is prohibited Only other user equipmenies occupy resource scheduling information corresponding resource.

Second base station receives the resource scheduling information of first base station transmission, and the second base station can check resource scheduling information pair Answer resource whether occupied, if unoccupied, forbidding should for other user equipmenies distribution in the second base station range The corresponding resource of resource scheduling information, and the information for allowing scheduling is returned to first base station；If occupied, when until When the resource is released, the information for allowing scheduling can be returned to first base station, or can not permit to current base station return directly Perhaps the information dispatched, such first base station are that user equipment is true in the information for not allowing scheduling for receiving the return of the second base station Then fixed other resource scheduling informations into row data communication carry out the coordination of scheduling of resource, Zhi Dao according still further to the step 102 User equipment of the resource of one base station distribution not by the covering of the second base station occupies, and the second base station will be returned to first base station to be allowed The information of scheduling.

Step 103, when the information for allowing scheduling for receiving the return of the second base station, uplink authorization is sent to user equipment, So that the user equipment enterprising row data communication of resource scheduling information corresponding resource in the serving cells.

It should be noted that after the resource scheduling information corresponding resource is discharged by user equipment, first base station can be with Resource is discharged into successful information and is sent to the second base station, such second base station can forbid other user equipmenies to occupy the money The corresponding resource of source scheduling information.And above-mentioned first base station is between the second base station when being communicated, for example send resource tune When degree information and reception allow the information of scheduling, need to be communicated by BTS management unit.

As it can be seen that in the method for the present embodiment, the first base station where user equipment serving cell can be the user equipment It determines and is sent to the second base station into the resource scheduling information of row data communication, and by the resource scheduling information in serving cell, it should Second base station is the base station where the cooperation cell of user equipment, so that the second base station forbids other user equipmenies to occupy the money The corresponding resource of source scheduling information；The information for allowing scheduling of the second base station return is received, first base station can send uplink and award It weighs to user equipment, allows the user equipment above-mentioned enterprising row data communication of resource scheduling information corresponding resource in the serving cells. Pass through the second base station and negotiation of the first base station for resource scheduling information in this way, so that it may to avoid the user between each base station Conflict of the equipment to resource allocation, realizes the interference coordination of each cell, so as to avoid the data of cooperation cell user equipment Communicate the interference of the data communication to this cell user equipment.

Refering to what is shown in Fig. 2, in a specific embodiment, first base station is in addition to that can execute above-mentioned steps 101 to 103 Before, following steps 104 and 105 can also be executed, specifically before step 101：

Step 104, Physical Broadcast Channel information is sent in the serving cells, includes current in Physical Broadcast Channel information The available multiple targeting sequencing group such as Physical Random Access Channels of cell（Physical Random Access Channel, PRACH）The call number of targeting sequencing group.

In the present embodiment, random access channel preamble sequence is grouped, may include in each grouping it is multiple with Machine targeting sequencing, and the corresponding resource scheduling information of each targeting sequencing in same grouping is the same.

First base station is when sending Physical Broadcast Channel information, in order to enable the information of first base station transmission is less, it can be with The call number of targeting sequencing group is associated with resource scheduling information using recessive manner, index of reference number is used as targeting sequencing group The identification information of corresponding resource scheduling information, and be carried in Physical Broadcast Channel information, i.e., by each targeting sequencing group pair If the resource scheduling information answered is identified by the fix information of kilo byte, biography can be passed through in communication so afterwards The defeated identification information carrys out scheduling resources transmitted information, rather than directly transmits actual resource scheduling information so that first base station The bit number transmitted between user equipment can reduce.Specifically, first base station carries the call number of multiple targeting sequencing groups To being sent in Physical Broadcast Channel information, wherein call number is used to indicate the scheduling of resource of the user equipment of corresponding targeting sequencing group Information.

After first base station sends above-mentioned Physical Broadcast Channel information, user equipment receives the Physical Broadcast Channel information, Then one of targeting sequencing group can be selected in multiple available targeting sequencing groups indicated by Physical Broadcast Channel information, used Family equipment specifically can be according to actual data service（Such as MTC service）It determines the size for needing transmission data and needs to occupy The resource informations such as running time-frequency resource, and selected in available targeting sequencing group according to determining resource information one it is suitable before Lead sequence group；User equipment can select a targeting sequencing at random in the targeting sequencing group of selection, and be initiated to first base station Random access request may include the corresponding call number of randomly selected targeting sequencing group in the random access request.Wherein Due to the correspondence of the call number and resource scheduling information that preset each targeting sequencing group in user equipment side, then user sets It is standby after determining resource information according to actual data traffic, so that it may with by the resource in the resource information and preset correspondence Scheduling information is compared, and determines the resource scheduling information consistent with the resource information, then determines that resource information institute is right again Then the call number answered which corresponding targeting sequencing group is known that according to determining call number, then the targeting sequencing group is to use The suitable targeting sequencing group that family equipment is selected according to determining resource information.

Step 105, the random access request that user equipment is sent is received, includes user equipment root in random access request According to the call number for the targeting sequencing group that Physical Broadcast Channel information determines.Due to also presetting targeting sequencing group in first base station side Call number and resource scheduling information correspondence, then first base station in the determination step in executing above-mentioned steps 101, tool Body can be parsed from random access request obtains user equipment determination targeting sequencing group call number, determine user equipment into The resource scheduling information of row data communication.

It is appreciated that the above-mentioned user equipment targeting sequencing used when initiating random access request is mainly used in base station Lateral areas divides user equipment identity, and completes the propagation delay time estimation and correction of user equipment.If user equipment will initiate Row transmission, it is necessary first to carry out down-going synchronous, obtain some necessary cell level knowledges, but user equipment is not in down-going synchronous There is correction propagation delay time；After user equipment initiates random access request, first base station can be determined according to the targeting sequencing detected Allow the user equipment for carrying out transmitting uplink data, and tells uplink and downlink overall delay information to user equipment, such user equipment It is corrected according to Delay, to can be achieved with the time synchronization with first base station.Wherein, user equipment and first base station The meaning of time synchronization is, if first base station notifying user equipment transmission data, and upstream data is received in assigned timeslot, So user equipment needs to adjust its data transmission time so that data are actually reached the time slot of first base station and assigned timeslot is kissed It closes.

It should be noted that the step 104 and 105 in the present embodiment can be independently of resources in above-mentioned steps 101 to 103 The coordination of scheduling forms an individual embodiment, to reduce the data volume communicated between user equipment and first base station, in this way First base station is after executing 105, so that it may the uplink of the user equipment is known with the call number for including according to random access request Data are probably in which resource.

Refering to what is shown in Fig. 3, in another specific embodiment, in order to simplify user equipment from random access to transmission on The flow of row data can save the resource tune that user equipment active request carries out scheduling of resource and first base station to user equipment The step of degree request is handled, specifically, first base station executes above-mentioned steps 104 and following steps before above-mentioned steps 101 Rapid 106, and after executing step 104 and 106, by preset time, then the step of executing blind examination i.e. step 107 and 108, specifically Ground：

Step 106, targeting sequencing is carried out in the resource of all Physical Random Access Channels（preamble）Detection, is obtained The call number of the targeting sequencing group where the targeting sequencing of user equipment selection is taken, then first base station is executing above-mentioned steps 101 When, it is that resource scheduling information is determined according to the call number of the targeting sequencing group detected.

Step 107, the upper line number that user equipment is detected on running time-frequency resource into row data communication is corresponded in resource scheduling information According to.

Step 108, the upstream data of user equipment is received on the running time-frequency resource detected.

It is appreciated that only specifying the upstream data of user equipment transmission in resource scheduling information indicated by call number The maximum frequency domain resource block that may be occupied, but not specified upstream data specifically occupies which part in a monoblock resource. The blind examination process of above-mentioned steps 107 and 108 is exactly to traverse all possible time/frequency source block, to each resource block all attempt into Row demodulation obtains the upstream data of user equipment and the running time-frequency resource actually occupied if demodulation result is correct, if time Going through still cannot obtain correct demodulation result after all resource blocks, then blind examination fails.

In addition, it is necessary to explanation, above-mentioned preset time can be greater than or equal to first base station with the second base station according to upper The method for stating step 101 to 103 carries out the time of scheduling of resource coordination, can give first base station with the second base station with enough in this way Time negotiate user equipment whether can according to determining resource scheduling information carry out upstream data transmission, then carry out again The blind examination of row data ensures that first base station can detect the upstream data of user equipment as possible.And in the present embodiment, first base station After executing step 104, before being detected in all possible PARCH resources where the targeting sequencing of user equipment selection After the call number for leading sequence group, step 101 to 103 is executed, and without the random access request of response user equipment initiation, in this way The interaction flow between first base station and user equipment can be saved.

Further, in this embodiment user equipment, which can not need active request, carries out scheduling of resource, but by first Base station directly transmits the call number of various available targeting sequencing groups, and call number is associated with resource scheduling information, comes User equipment oneself is allowed to determine resource scheduling information；And due to base station can according to the resource scheduling information that gets, it is all can Directly the upstream data of user equipment is detected in the resource of energy, it may not be necessary to which user equipment sends slow to first base station Rush zone state report（Buffer State Report, BSR）, come the upstream data for telling first base station user equipment to send The information such as size and location.To simplify user equipment from random access first base station to the flow for sending upstream data.

It is further to note that step 104,105 and 107 and 108 in the present embodiment can be independently of above-mentioned steps The coordination of scheduling of resource in 101 to 103 forms an individual embodiment, to reduce between user equipment and first base station Communication process, such first base station is after executing 106, so that it may know the use with the call number for including according to random access request The upstream data of family equipment can perform in above-mentioned steps 107 and 108 probably in which resource after the preset time Blind examination.

And step 107 in the present embodiment and 108 can also be independently of the association of scheduling of resource in above-mentioned steps 101 to 103 It adjusts, an individual embodiment is formed, to reduce the communication process between user equipment and first base station.Specifically, the first base It stands after distributing resource scheduling information for user equipment, is held blind examination can be proceeded by after certain preset time Row step 107 and 108.

The method of the present invention embodiment two
