It should be noted that, in the embodiment of the present invention, said matching operation is not limited to two users, can make a general reference a plurality of users; User terminal refers to the user terminal of access base station, comprises scheduling user terminal and not scheduling user terminal.
Embodiment 1:
One embodiment of the present of invention provide a kind of method of transfer of data, as shown in Figure 1, comprise the steps:
101, from choosing first user terminal to be matched scheduling user terminal.
Scheduling user terminal is that base station has been distributed for transmitting the channel of data and having carried out the user terminal of relative set.The first user terminal to be matched is scheduling user terminal.
102, judge the type of service of described the first user terminal to be matched.
The type of service of the first user terminal to be matched has two kinds, and a kind of is GBR (Guaranteed Bit Rate guarantees bit rate) business, and another kind is Non-GBR (Non-Guaranteed Bit Rate, non-ensured bit rate) business.QOS(Quality Of Service, service quality) be the regulation of the difference requirement of transfer rate being carried out according to the different business of user terminal, comprise channel quality indication, service priority, the time delay of packet, packet loss, resource type etc.Wherein resource type is divided into GBR and Non-GBR.QOS is in each host-host protocol, as LTE(Long Term Evolution, Long Term Evolution) agreement and LTE-A (Long Term Evolution-Advanced, follow-up Long Term Evolution) agreement etc., there is specified in more detail.The implementation of step 102 can be: according to the resource type of the first user terminal QOS to be matched, obtain the type of service of the first user terminal to be matched, the type of service that then judges the first user terminal to be matched is GBR business or Non-GBR business.
103, when the described type of service of described the first user terminal to be matched is Non-GBR business, never in scheduling user terminal, choose N-1 the second user terminal to be matched, wherein N is the sum that system allows the user terminal of pairing, and is more than or equal to 2.
104, N-1 the second user terminal to be matched and the first user terminal to be matched are matched, form multi-antenna terminal group.
105, carry out the transfer of data of multi-antenna terminal group.
The present embodiment provides a kind of method of transfer of data, first, from choosing first user terminal to be matched scheduling user terminal, then judges the type of service of described the first user terminal to be matched; When the described type of service of described the first user terminal to be matched is Non-GBR business, N-1 the second user terminal to be matched and described the first user terminal to be matched are matched, so that transfer of data is carried out by described the first user terminal to be matched and described N-1 the second user terminal composition multi-antenna terminal group to be matched in base station.By such scheme, stop the user terminal of GBR business to match, improved the service quality of business.
Embodiment 2:
One embodiment of the present of invention provide a kind of method of transfer of data, as shown in Figure 2, comprise the steps:
201, from choosing first user terminal to be matched scheduling user terminal.
202, judge the type of service of described the first user terminal to be matched.
According to QOS, judge that the type of service of the first user terminal to be matched is GBR business or Non-GBR business.
The concrete mode of performing step 202 can be, the service request that the first user terminal to be matched is sent to base station is mated with the business of stipulating in host-host protocol, and the business matching with service request is the business of the first user terminal to be matched.The resource type of then checking the business of described the first user terminal to be matched is GBR business or Non-GBR business.
203,, when the described type of service of described the first user terminal to be matched is GBR business, indicate described the first user terminal to be matched to use the channel having distributed to carry out separately transfer of data.
GBR business is that actual transfer rate must be higher than the business of regulation transfer rate, otherwise the phenomenon that there will be quality of service not meet customer need, talk business is in real time typical GBR business, if the regulation transfer rate of business is 100kb/s (kilobyte/second, kilobytes/second), actual transfer rate is 80kb/s, and, in communication process, user may can only hear desultory sound.
It is known according to the principle of MU-MIMO system: after the first user terminal to be matched and N-1 the second user terminal to be matched matches, the first user terminal to be matched and N-1 the second user terminal to be matched are made to the as a whole transfer of data of carrying out, can improve like this data throughout of base station in the unit interval, it is the transfer rate of base station, described N is the sum that system allows the user terminal of pairing, and is more than or equal to 2.But this need to sacrifice the transfer rate of the first user terminal to be matched.After the user terminal A that comprises GBR business (supposing that user terminal A is the first user terminal to be matched) is matched, the transfer rate of user terminal A can reduce, if during lower than the transfer rate of the GBR operation regulation of user terminal A, this GBR business just can not meet service request.For eliminating this defect, therefore need to stop the first user terminal to be matched that comprises GBR business to carry out MU-MIMO pairing.
Further, also provide a kind of method of transfer of data, as shown in Figure 3, the method comprises the steps:
301, from choosing first user terminal to be matched scheduling user terminal.
In the mode of choosing the first user terminal to be matched from scheduling user terminal, both can choose at random, and can in the order of set of terminal, choose successively according to user terminal yet, the present embodiment does not limit.
302, judge the type of service of described the first user terminal to be matched.
According to QOS, judge the type of service of the first user terminal to be matched.
When the type of service of the first user terminal to be matched is GBR business, perform step 303.
When the type of service of the first user terminal to be matched is Non-GBR business, perform step 304.
303,, when the described type of service of described the first user terminal to be matched is GBR business, indicate described the first user terminal to be matched to use the channel having distributed to carry out separately transfer of data, i.e. SU-MIMO transmission.
304,, when the described type of service of described the first user terminal to be matched is Non-GBR business, never in scheduling user terminal, choose N-1 the second user terminal to be matched.
The first user terminal to be matched is for dividing the user terminal of the channel that is used in transmission data, N-1 the second user terminal to be matched is there is no the user terminal that minute is used in the channel that transmits data, N is the sum that system allows the user terminal of pairing, and is more than or equal to 2.
Choose the method for N-1 the second user terminal to be matched and both can choose at random, can in the order of set of terminal, choose successively according to user terminal yet, the present embodiment does not limit.
305, judge that the total speed of business after the pre-pairing of the first user terminal to be matched and N-1 the second user terminal to be matched is whether higher than the service rate of the first user terminal to be matched.
The service rate of the first user terminal to be matched refers to service rate when the first user terminal to be matched carries out SU-MIMO transfer of data.
The Rule of judgment of step 305 is that the total speed of business of the multi-antenna terminal group in order to guarantee to be composed of will be higher than the service rate of the first user terminal to be matched.Only after meeting the Rule of judgment of step 305, can form multi-antenna terminal group, make user terminal with multi-antenna terminal Zu Wei unit, realize together and base station between data input and data output.
Obviously in step 305, selected altogether N user terminal (1 the first user terminal to be matched and N-1 the second user terminal to be matched).
The following describes the process of the total speed of business of obtaining after pre-pairing:
According to prior information, N the user terminal of selecting carried out to MU-MIMO and match in advance, calculate the total service rate after service rate after the pre-pairing of the first user terminal to be matched and a described N user terminal match in advance.
Service rate after the pre-pairing of the first user terminal to be matched refers to that described the first user terminal to be matched and described N-1 the second user terminal to be matched form after multi-antenna terminal group, the service rate of described the first user terminal to be matched.
Total service rate after N the pre-pairing of user terminal refers to described the first user terminal to be matched and the service rate sum of individual the second user terminal to be matched of described N-1 after pre-pairing, the i.e. total speed of business described in step 305.
The total speed of business after service rate after the pre-pairing of the first user terminal to be matched and a described N user terminal match in advance is all recorded in the tables of data that base station provides.
In particular cases, the value of N is 2, and situation is now that first user terminal to be matched and second user terminal to be matched match in advance.More common situation is that the value of N is greater than 2, matches in advance with more than 2 user terminals.
In the tables of data that system provides, record the user terminal calculating and carried out the service rate of SU-MIMO transmission and the service rate after pre-pairing.The service rate of the first selected user terminal to be matched is that described user terminal is in the transfer rate of carrying out SU-MIMO.In practical application scene, described data table stores, in base station, can be obtained the data that are recorded in tables of data as required at any time.
Now illustrate the deterministic process of step 305.If the first user terminal to be matched is A, it is that 2(is N=3 that system allows the second user terminal number to be matched of pairing), the second user terminal B1 to be matched, B2.In the tables of data providing in MU-MIMO system control protocol, find: the service rate of user terminal A is 10000 bps, after pre-pairing, service rate is 6200 bps; Service rate after the pre-pairing of user terminal B1 is 3200 bps, and the service rate after the pre-pairing of user terminal B2 is 3600 bps.Through judgement, the type of service of the first user terminal A to be matched is Non-GBR business, A and N-1 the second user terminal to be matched is matched in advance.A and N-1 the second user terminal B1 to be matched, the total speed of business after the pre-pairing of B2 is 6200+3200+3600=13000 bps.Total be exactly step 305 is specific to the size that judges 10000 bps of speed before the pre-pairing of 13000 bps of described speed and the first user terminal A to be matched in this example.Obviously, the total speed in this example is greater than the speed before the pre-pairing of user terminal A, should perform step 306.
The total speed of business after the pre-pairing of the first user terminal to be matched and N-1 the second user terminal to be matched during higher than the service rate of described the first user terminal to be matched, performs step 306.
The total speed of business after the pre-pairing of the first user terminal to be matched and N-1 the second user terminal to be matched during not higher than the service rate of described the first user terminal to be matched, performs step 307.
306, the first user terminal to be matched and N-1 the second user terminal to be matched are matched, so that the transfer of data of multi-antenna terminal group, by the first user terminal to be matched and N-1 the second user terminal to be matched, is then carried out in base station.
If other N-1 described the second user terminal to be matched that the total speed of business after the pre-pairing of 307 first user terminals to be matched and N-1 the second user terminal to be matched not higher than the service rate of described the first user terminal to be matched, reselects except described N-1 the second user terminal to be matched matches.
When the Rule of judgment described in step 307 is set up, reselect N-1 the second user terminal to be matched, then perform step 305.All user terminals in the second set of terminal all participate in after pre-pairing, still can not find the total speed of business after the pre-pairing of N-1 the second user terminal to be matched and the first user terminal to be matched to be greater than the service rate of the first user terminal to be matched, do not meet the Rule of judgment of step 305, the first user terminal to be matched can only carry out SU-MIMO transmission.
Illustrate step 301 to 307, establish the first user terminal A to be matched, the second user terminal to be matched is B, C, D, E, F, G.The quantity that system allows to carry out the second user terminal to be matched of MU-MIMO pairing is 2, i.e. N=3.Through judgement, the type of service of the first user terminal A to be matched is Non-GBR business, first by A and B, C matches in advance, if A, B, the total speed of business after the pre-pairing of C is not higher than the business of A, other N-1 described the second user terminal to be matched reselecting except described N-1 the second user terminal to be matched carries out described pairing, chooses D, and E matches in advance.Due to B, C has participated in pre-pairing, so the selectable object of inferior pre-pairing is D, and E, F, G.If A, D, the total speed of business after the pre-pairing of E is higher than the business of A, by A, D, E matches.The service rate of A refers to data when user terminal A is carried out SU-MIMO transmission, in this example, can be understood as the service rate before pre-pairing.
It should be noted that, the mode of choosing N-1 the second user terminal to be matched can be to choose according to sequencing, but also chooses at random, and the present embodiment does not limit.
The present embodiment provides a kind of method of transfer of data, first choose first user terminal to be matched, then according to service quality QOS, judge that described the first user terminal to be matched is GBR business or Non-GBR business, on the one hand, prevention type of service is that the first user terminal to be matched of GBR business matches, on the other hand, by type of service, be that the first user terminal to be matched of Non-GBR business and N-1 second user terminal to be matched matches.Pass through such scheme, distinguish the type of service of user terminal, user terminal is matched, on the one hand, the transfer rate of the first user terminal to be matched that assurance comprises GBR business, on the other hand, guarantee the overall transmission rate of the first user terminal to be matched and N-1 second user terminal to be matched of Non-GBR business, improved the service quality of business.
