Detailed description of the invention
Fig. 1 is the schematic flow sheet of uplink transmission parameter system of selection one embodiment of the present invention, including:
Step 11 a: base station obtains the dispatch situation of adjacent base station；
Wherein, the signal intensity obtaining UE to base station can be measured in base station, and can also measure interference level value interferencelevel when obtaining scheduling and noise level value noiselevel；Afterwards, base station just can be estimated the channel quality between user and base station according to signal intensity, interferencelevel and noiselevel, and distribute certain running time-frequency resource for user accordingly.The running time-frequency resource of distribution can use Physical Resource Block (PhysicalResourceBlock, PRB) to represent.Therefore, base station may determine that as which PRB UE distributes when scheduling.
The dispatch situation of one base station includes the resource for communication that this base station is distributed by its at least one serviced UE.Such as can obtain which PRB is allocated to which UE use by adjacent base station by X2 interface by the mutual dispatch situation obtaining the other side between adjacent base station.
Step 12: this base station is according to described dispatch situation, determine the first interference level value, described first interference level value is the interference level value from the 2nd UE that a UE is subject to when transmitting uplink data, a described UE is the UE that UE, described 2nd UE are the service of described adjacent base station of this base station service；
First, base station according to the dispatch situation of adjacent base station, can determine the interference user of this community UE, and wherein, user is referred to as UE；For example, with reference to Fig. 2, including two base stations and three users, respectively base station 1, base station 2 and user 1, user 2 and user 3, user 1 is the user of base station 1 service, and user 2 and user 3 are the user of base station 2 service.Assuming that the running time-frequency resource of user 1 is distributed in base station 1 is PRB1, and to distribute to the running time-frequency resource of user 2 be also PRB1 in base station 2, then from the point of view of user 1, user 2 disturbs user exactly.
Secondly, after determining interference user, can be by the monitor value of interference user being obtained interference level value, wherein, the monitor value of interference user can have been monitored and obtained；Such as, base station monitors the measuring reference signals (SoundingReferenceSignal, SRS) from each user in real time, carries out signal strength measurement and carries out record, after determining interference user, just the signal strength values that the SRS measurement according to its correspondence obtains is defined as interference level value.First interference level value is the interference level monitoring the 2nd UE obtained when the unscheduled UE in described base station to a UE, can be that base station monitors the 2nd UE obtained interference level value to a UE after having dispatched a UE in real time.When not being scheduling a UE, base station also can be detected and obtain the first interference level value, and using this first interference level value as UE transmitting uplink data time the interference level value from the 2nd UE that is subject to.
Step 13: the signal intensity from a described UE, the noise level value of this base station described and the described first interference level value that this base station detects according to this base station described, determines the first uplink transmission parameter；
Wherein, signal detection can be passed through in base station, obtain this base station service UE send signal arrive base station time signal intensity, i.e. obtain the signal intensity from a described UE that this base station detects；It addition, base station can also obtain, by detection, the noise level value that device produces in base station, i.e. obtain the noise level value of this base station；Unlike the prior art time, the embodiment of the present invention computationally row transmission parameter, i.e. when calculating the information such as RI, PMI, CQI, the interference level value used is not interference level value during scheduling, such as, seeing Fig. 2, when scheduling, base station 2 is probably scheduling user 3 rather than user 2, then according to interference level value during scheduling the most specifically according to the signal strength values of user 3 correspondence.Owing to interference during interference during this base station scheduling one UE and UE row transmission data actually there may be larger difference, the present embodiment selects uplink transmission parameter will be the most accurate according to the UE interference level value when uplink transmission data.
It is understood that owing to signal intensity, noise level value change over less, its signal intensity that still can obtain with measurement during selection scheduling and noise level value.
Step 14: this base station sends descending control signaling, to indicate a described UE to transmit the upstream data corresponding with described first uplink transmission parameter when transmitting uplink data to a described UE.
Can comprise the first uplink transmission parameter in this descending control signaling, now, UE can use this first uplink transmission parameter to send after obtaining the upstream data of correspondence after initial data is carried out data genaration；Or, this descending control signaling can comprise instruction information, for indicating UE to upload the data block corresponding with the first uplink transmission parameter, UE has generated multiple data block, in order to the data block that UE transmission is corresponding with the first uplink transmission parameter.Particular content may refer to following embodiment.
Accordingly, the flow process seeing the execution of Fig. 3, UE side may include that
Step 31 a: UE receives the descending control signaling that base station sends；
Wherein, a UE is the UE of this base station service.
Step 32 a: UE determines, according to described descending control signaling, the data that the first uplink transmission parameter is corresponding, described first uplink transmission parameter is that the signal intensity from a UE, the noise level value of described base station and the first interference level value detected according to described base station determines, described first interference level value is the interference level value from the 2nd UE that a described UE is subject to when transmitting uplink data, a described UE is the UE of the adjacent base station that UE, described 2nd UE the are described base station service of described base station service；
Step 33 a: UE, when transmitting uplink data, sends the data that described first uplink transmission parameter is corresponding to described base station.
Optionally, if described descending control signaling comprises the first uplink transmission parameter, then a UE uses described first uplink transmission parameter that initial data is carried out data genaration, obtain the upstream data that described first uplink transmission parameter is corresponding, data genaration such as includes cyclic check (CyclicRedundancyCheck, CRC), code block cutting, chnnel coding, rate-matched and modulation etc.；Or, if described descending control signaling comprises instruction information, then a UE receives the instruction information that base station sends, from the data block of described at least two, the data that described first uplink transmission parameter is corresponding are determined according to described instruction information, now, the data block of the upload transfers parameter combination producing at least two of at least two groups that a UE has the most sent according to base station.
Optionally, descending control signaling can use group mark to scramble, and a UE receives descending control signaling in subframe set in advance and uses predetermined group of mark to descramble, and obtains the first corresponding for UE uplink transmission parameter or an instruction information.
The present embodiment determines the first uplink transmission parameter according to the UE interference level value when transmitting uplink data, and use the first uplink transmission parameter transmission data, owing to uplink transmission parameter determines according to interference during transmitting uplink data, rather than interference during scheduling, the most there is not scheduling and latency issue during actual transmissions data, more suitably uplink transmission parameter can be selected, improve upstream performance.
Fig. 4 is the schematic flow sheet of uplink transmission parameter another embodiment of system of selection of the present invention, including:
Step 41: base station, when dispatching UE, is distributed running time-frequency resource for UE and determines the second uplink transmission parameter.
Wherein, as it has been described above, base station can be that UE distributes running time-frequency resource according to signal intensity, interference level value, noise level value.
Unlike second uplink transmission parameter and the first uplink transmission parameter, the interference level value of the second uplink transmission parameter foundation is interference level value during scheduling, and the first uplink transmission parameter is based on interference level value during transmitting uplink data.Interference level value during scheduling is the second interference level value, can be that described UE is handed down to dispatching UE when in base station.Interference level value during transmitting uplink data is the first interference level value, can be that the interference level value obtained is detected in base station when not being scheduling, monitor in real time other UE to as described in the interference level value that obtains of the disturbed condition of UE.
Step 42: the second uplink transmission parameter is carried and is sent to UE in uplink scheduling order (ULgrant) by base station.
Step 43: base station obtains the dispatch situation of adjacent base station, and determines the first uplink transmission parameter according to dispatch situation.
Determine that the flow process of the first uplink transmission parameter can be referring specifically to a upper embodiment.
Step 44: the first uplink transmission parameter is carried and is sent to UE in adjusting signaling by base station.
Wherein, above-mentioned ULgrant and adjustment signaling can be descending control signaling (DownlinkControlInformation, DCI), specifically can use DCIformat4.
After UE receives adjustment signaling, uplink transmission parameter adjustment will be carried out, be adjusted to the first uplink transmission parameter from the second uplink transmission parameter.
Step 45:UE is when transmitting uplink data, according to the first uplink transmission parameter transmission upstream data.
It should be noted that the present embodiment first sends a uplink transmission parameter to UE with base station, as a example by adjusting uplink transmission parameter the most again.Optionally, base station only can also send the uplink transmission parameter after once adjusting to UE, and namely base station does not sends the second uplink transmission parameter to UE when scheduling, but just the first uplink transmission parameter is sent to UE when determining the first uplink transmission parameter.
The present embodiment, by adjusting uplink transmission parameter, so that UE uses more particularly suitable uplink transmission parameter transmission upstream data, improves upstream performance.
Fig. 5 is the schematic flow sheet of uplink transmission parameter another embodiment of system of selection of the present invention, including:
Step 51: base station, when dispatching UE, is distributed running time-frequency resource for UE and determines many group uplink transmission parameter combinations.
Unlike a upper embodiment, a upper embodiment is to determine one group of up parameter combination (RI/PMI/CQI) according to interference level value during scheduling；And the present embodiment is each UE determines and organize RI/PMI/CQI more, such as RI1/PMI1/CQI1 and RI2/PMI2/CQI2.Wherein, the up parameter combination of many groups can be determined according to multiple possible interference level value, such as, under the scene shown in Fig. 2, base station 1 can determine the combination RI1/PMI1/CQI1 corresponding when interference is user 2, and combination RI2/PMI2/CQI2 corresponding when interference is user 3 respectively.
Step 52: base station is carried and is sent to UE by organizing uplink transmission parameter combination more in uplink scheduling order (ULgrant).
Step 53:UE generates multiple data block respectively according to uplink transmission parameter combination.
Such as, generate data block 1 according to initial data and RI1/PMI1/CQI1, and generate data block 2 according to initial data and RI2/PMI2/CQI2.
Step 54: base station obtains the dispatch situation of adjacent base station, and determines the first uplink transmission parameter according to dispatch situation.
Step 55: base station sends to UE and adjusts signaling, wherein carries instruction information, this instruction information selects the data block corresponding with the first uplink transmission parameter for indicating UE.
Such as, the first uplink transmission parameter includes RI1/PMI1/CQI1, it indicates that information instruction selects data block 1.
In addition, it is necessary to explanation, the parameter group determined during step 51 merges and not necessarily comprises the first uplink transmission parameter, then the data block corresponding with the first uplink transmission parameter refers to the data block generated according to the parameter closest to the first uplink transmission parameter.Such as, predetermined multiple combinations do not comprise RI1/PMI1/CQI1, and in predetermined combination, RI2/PMI2/CQI2 is closest to RI1/PMI1/CQI1's, then instruction information may indicate that the data block generated according to RI2/PMI2/CQI2.
Furthermore, instruction information is also not necessarily limited to indicate a data block, it is also possible to indicate multiple data block, such as, the data block that instruction generates according to the uplink transmission parameter of the setting number being closer to the first uplink transmission parameter.
Step 56:UE, when transmitting uplink data, transmits the data block of instruction information instruction.
The present embodiment is by adjusting uplink transmission parameter, so that UE transmits the upstream data that more particularly suitable uplink transmission parameter is corresponding, improves uplink.
When implementing, the adjustment signaling of the embodiment shown in Fig. 4 or Fig. 5 can use UEid to scramble, then UE uses the UEid of self to carry out descrambling to obtain the first uplink transmission parameter or instruction information when receiving descending control signaling.It is to say, above-described embodiment is by one by one as a example by UE sends the first uplink transmission parameter or instruction information, optionally, it would however also be possible to employ the mode of group sends.

Wherein, descending control signaling comprises the first corresponding for multiple UE uplink transmission parameter or instruction information.
It addition, use from above-described embodiment unlike UEid scrambling, descending control signaling employing group mark (groupid) scrambling of the present embodiment.
Group mark can be the function of the subframe numbers of scheduling sublayer frame, and such as, at the UE that subframe n is scheduled, its affiliated group is designated the concrete form of f (n), f (n) and can set.Or, group mark can also be to be notified independently to each UE by base station.
For each UE, its corresponding descending control signaling position in group, UE can be sent jointly to the second uplink transmission parameter.
Step 62:UE receives descending control signaling employing group mark descrambling, obtains the first uplink transmission parameter or instruction information.
UE can receive descending control signaling in subframe set in advance, and such as, base station is dispatched UE, UE and transmitted upstream data when subframe n+4 when subframe n, then transmit this descending control signaling when can be set in advance in subframe n+2.So, all of UE just can receive descending control signaling and use the group mark of self to descramble when subframe n+2, if it is possible to successfully descrambles and shows to comprise the information of self, and obtain the information of self, such as the first uplink transmission parameter or instruction information.
It addition, descending control signaling in the present embodiment comprises information corresponding to multiple UE, then the position at information place corresponding for each UE can be preset.Such as, one group comprises the information of 3 UE, each information takies two bits, the information corresponding for UE1 that so can preset identification number minimum is positioned at the first two bit, identification number is in the information corresponding for UE2 of centre and is positioned at middle two bits, and the information corresponding for UE3 of identification number maximum is positioned at last two bits.
Step 63:UE is when transmitting uplink data, to the data block that base station transmission is corresponding with the first uplink transmission parameter.
Obtaining the flow process after the first uplink transmission parameter or instruction information can be referring specifically to the embodiment shown in Fig. 4 or Fig. 5.
On the basis of above-described embodiment, the information of multiple UE is transmitted together by the present embodiment by group mark, it is also possible to reduce transport overhead.
