Description
Technical field
The present invention relates to communication technical field, particularly a kind of technology of reporting parameters.
Background technology
In existing mobile communication system, subscriber equipment (User Equipment, UE), before initial initiation business, need to carry out a random access procedure.By this process, UE reports parameter to network side, to make network side can know the quality of UE up link, thereby carries out the distribution of ascending resource.
If the uplink quality of UE is better, network side can be distributed to the ascending resource that this UE is larger in the situation that allowing, and UE can transmit larger data block; If the uplink quality of contrary UE is poor, network side distributes less ascending resource can to this UE, and UE can only transmit less data block.
Before UE initiating random access procedure, between UE and network side also without any connection, so now network side cannot obtain by the measurement of self quality of the up link of this UE, need UE to inform the quality of this UE up link of network side by the message of uplink.After this, network side can be according to the corresponding resource of the mass distribution of UE up link to UE.Therefore, UE need to be in the quality of up link with informing this UE of network side in connecing access procedure.
UE can judge according to network side the quality good or not of up link to path loss (Pathloss, the PL) situation between UE.
Under current system,, only there is a up link in point-to-point transmission between UE and base station.Therefore, UE can judge the quality of up link and report the quality of its up link to network side to the path loss between this base station according to UE, thereby know at network side after the quality of UE up link, the size of the ascending resource of this UE is distributed in decision, avoids UE in the time that uplink quality is poor to transmit larger data block or the less data block of UE transmission in the time that uplink quality is better.
Under evolution system, UE can receive and transmission information from multiple access points (Access Point, AP) simultaneously.When UE faces multiple AP, between UE and each AP that can communicate by letter with it, all there is a up link, that is to say that UE can receive data from the different AP of different communities or same community, also can send data to these AP.
In the time there is multiple AP, what UE cannot utilize that point-to-point transmission adopts reports mode to network side reporting uplink link-quality.Network side also just cannot judge the size of the resource of distributing to subsequent data transmission thus.Now, UE may, in the time that uplink quality is all poor, transmit larger data block, causes error in data or loss, or causes data re-transmission; UE also may, in the time that uplink quality is all better, transmit less data block, causes the wasting of resources.

Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the present invention is described in further detail.
In each of the embodiments described below, wireless communication system is take LTE evolution system as example, but can generally be applied in other wireless communication systems, for example, be applied in LTE system.In each of the embodiments described below, take preamble code and random access guiding (Random Access Preamble) message as example, but be not limited to preamble code and Random Access Preamble message, those of ordinary skills are known, Random Access Preamble message can be other upstream message, and preamble code can be the parameter that can indicate uplink quality of carrying in other upstream message.
In random access procedure, UE can send Random Access Preamble message to network side, carries preamble code in this message; Network side receives after Random Access Preamble message, sends accidental access response (Random Access Response) message to UE, indicates UE network side to distribute to the resource of this UE in this message; UE receives after Random Access Response message, sends scheduling transmission (Scheduled Transmission) message to network side, can transmit larger data block and also can transmit less data block in this message.Wherein preamble code is the parameter that is used to indicate UE uplink quality.
Can be by reporting preamble code for UE, the quality of this UE up link of indication network side, can represent different uplink qualities with different preamble codes.But because preamble code may be more, and the quality of indication up link does not need higher precision yet, so preamble code partly or completely can be divided into two groups or many groups, every group of preamble code represents different uplink qualities.Wherein, the quantity of preamble code character can determine according to the precision of the required uplink quality of network side.
For example, in the time that preamble code one has 64, can be divided into 2 preamble code characters, the 1st to the 32nd is first group, and the 33rd to the 64th is second group.When the preamble code of receiving when network side belongs to first group, just can think that the uplink quality of UE is poor, only need to distribute less ascending resource; And the preamble code of receiving when network side is while belonging to second group, just can think that the uplink quality of UE is better, can distribute more ascending resource.
Or, in the time that preamble code one has 64, can be divided into 3 preamble code characters, the 1st to the 20th is first group, and the 21st to the 40th is second group, and the 41st to the 61st is the 3rd group.The uplink quality of preamble representation UE in first group is poor, and the uplink quality of the preamble representation UE in second group is general, and the uplink quality of preamble representation UE in the 3rd group is better.
Therefore, can, by dividing several preamble code characters, represent the different quality of up link, UE should carry the preamble code in which preamble code character according to the quality judgement of up link in Random Access Preamble message.Network side is receiving after Random Access Preamble message, also can be by judging which code character preamble code that this message is carried belongs to and know the quality of the up link of this UE, thus distribute corresponding ascending resource.
In order to narrate conveniently, following each embodiment is all to be divided into 2 preamble code characters as example by all preamble codes, be respectively groupA and groupB, wherein the preamble representation uplink quality in groupA is poor, and the preamble representation uplink quality in groupB is better.The above-mentioned mode that preamble code is divided into groups does not limit the present invention in this packet mode, can also be impartial or unequal preamble code partly or completely is divided into two groups or more than two.
Select a preamble code in a certain preamble code character time, can be selective sequential or selection at random, can be also the rules selection set according to, for example, for selecting the preamble code of the preamble code difference minimum of transmitting with last time.

By first embodiment of the invention, UE can consider according to the quality comprehensive of multiple up links, from can indicate the corresponding preamble code character of uplink quality, selects preamble code to report network side.Thereby make the network side can be by judging that code character that this preamble code belongs to knows the quality of the up link of UE, thereby determine to distribute to the ascending resource of this UE.
Below in conjunction with accompanying drawing 2, describe the second embodiment of the present invention in detail.The second embodiment of the present invention also provides a kind of method of reporting parameters, and the method comprises:
UE, by receiving the system message of network side broadcast, obtains the transmitting power of the network side carrying in this system message.
Can also in system message, carry line loss threshold, this line loss threshold is identical for different AP, and UE obtains this line loss threshold by receiving system message.In addition, the line loss threshold of each AP also can be preset in UE.
UE is the transmitting power with the network side obtaining according to the received power of oneself, calculates the path loss of each AP to this UE.The account form of path loss is: the difference of network side transmitting power and UE received power.
Thus, UE obtains the path loss of each AP to this UE by calculating, is respectively PL1, PL2......PLn.The quantity that wherein n is AP, in following embodiment, n is the quantity of AP, repeats no more.
Between each circuit loss value and line loss threshold, different comparative approach all can be for judging the quality of comprehensive up link of this UE, then from represent the preamble code character of this quality, select a preamble code according to the quality of this comprehensive up link.
For example, more each circuit loss value and line loss threshold, from corresponding preamble code character, select preamble code, can be: in all circuit loss value, select minimum circuit loss value, if this circuit loss value is less than or is less than or equal to the line loss threshold of obtaining, UE selects a preamble code from groupB; Otherwise UE selects a preamble code from groupA.
A minimum circuit loss value is less than or equal to line loss threshold, just illustrates that the quality of at least one up link of this UE is better, so can meet the requirement of the data block that transmission is larger.Therefore, in groupB, select a preamble code to report network side, distribute larger ascending resource to UE with indication network side.
For example, more each circuit loss value and line loss threshold, from corresponding preamble code character, select preamble code, can also be: in all circuit loss value, select maximum circuit loss value, if this circuit loss value is less than or is less than or equal to the line loss threshold of obtaining, UE selects a preamble code from groupB; Otherwise UE selects a preamble code from groupA.
A maximum circuit loss value is less than or equal to line loss threshold, just illustrates that the quality of all up links of this UE is all better, so can meet the requirement of the data block that transmission is larger.Therefore, in groupB, select a preamble code to report network side, distribute larger ascending resource to UE with indication network side.
For example, more each circuit loss value and line loss threshold, from corresponding preamble code character, select preamble code, can also be: in all circuit loss value, select M circuit loss value, the method for selecting is from minimum circuit loss value, and order is selected M circuit loss value from small to large, if the M picking out circuit loss value is all less than or is less than or equal to the line loss threshold of obtaining, UE selects a preamble code from groupB; Otherwise UE selects a preamble code from groupA.Wherein, M is greater than 1 and be less than or equal to the integer of n, and M can be that network side is notified UE in UE and network side mutual, also can jointly be observed by UE and network side, and can be also that UE is self-determining, can also be preset in UE.The above-mentioned description for M value is also applicable to following each embodiment.
The M selecting a from small to large circuit loss value is less than or equal to line loss threshold, just illustrates that the quality of an at least M up link of this UE is better, so can meet the requirement of the data block that transmission is larger.Therefore, in groupB, select a preamble code to report network side, distribute larger ascending resource to UE with indication network side.
For example, more each circuit loss value and line loss threshold, from corresponding preamble code character, select preamble code, can also be: in all circuit loss value, select M circuit loss value, the method for selecting is from maximum circuit loss value, and descending order is selected M circuit loss value, if the M picking out circuit loss value is all greater than or is more than or equal to the line loss threshold of obtaining, UE selects a preamble code from groupA; Otherwise UE selects a preamble code from groupB.
Select from big to small M circuit loss value be greater than or equal to line loss threshold, just illustrate that the quality of an at least M up link of this UE is all poor, so may be difficult to meet the requirement of the data block that transmission is larger.Therefore, in groupA, select a preamble code to report network side, distribute less ascending resource to UE with indication network side.
For example, more each circuit loss value and line loss threshold, from corresponding preamble code character, select preamble code, can also be: in all circuit loss value, select M circuit loss value, the method of selecting is a random choose M circuit loss value, if the M picking out circuit loss value is all greater than or is more than or equal to the line loss threshold of obtaining, UE selects a preamble code from groupA; Otherwise UE selects a preamble code from groupB.
For example, more each circuit loss value and line loss threshold, from corresponding preamble code character, select preamble code, can also be: in all circuit loss value, select M circuit loss value, the method of selecting is a random choose M circuit loss value, if the M picking out circuit loss value is all less than in or is less than in the line loss threshold that equals to obtain, UE selects a preamble code from groupB; Otherwise UE selects a preamble code from groupA.
The M of a random choose circuit loss value is all less than or is greater than just explanation of line loss threshold, the quality of an at least M up link of this UE is all better or poor, therefore, from groupB or groupA, select accordingly a preamble code to report network side, distribute a larger or less ascending resource to UE with indication network side.
For example, more each circuit loss value and line loss threshold are selected preamble code from corresponding preamble code character, can also be: in the time meeting following condition, UE selects a preamble code from groupB; Otherwise UE selects a preamble code from groupA.Need satisfied condition be: the quantity that is less than or equal to the circuit loss value of line loss threshold is more than or equal to X with the ratio of quantity of the circuit loss value that is greater than line loss threshold; Or the quantity that is less than the circuit loss value of line loss threshold is more than or equal to X with the ratio of quantity of the circuit loss value that is more than or equal to line loss threshold; Or the quantity that is greater than the circuit loss value of line loss threshold is less than or equal to X with the ratio of quantity of the circuit loss value that is less than or equal to line loss threshold; Or the quantity that is more than or equal to the circuit loss value of line loss threshold is less than or equal to X with the ratio of quantity of the circuit loss value that is less than line loss threshold.Wherein, the most typical value of X is 1, and X can be that network side is notified UE in UE and network side mutual, also can jointly be observed by UE and network side, and can be also that UE is self-determining, can also be preset in UE.The above-mentioned description for X value is also applicable to following each embodiment.
It is 1 o'clock in X value, this function corresponding relation can be understood as, the quantity of circuit loss value that is less than line loss threshold is more than the quantity of circuit loss value that is greater than line loss threshold, that is to say, the quantity of the good up link of quality of this UE is more than the quantity of second-rate up link, so can meet the requirement of the data block that transmission is larger.Therefore, in groupB, select a preamble code to report network side, distribute larger ascending resource to UE with indication network side.
For example, more each circuit loss value and line loss threshold are selected preamble code from corresponding preamble code character, can also be: all circuit loss value are merged, if the circuit loss value PLmerger after merging
Be less than or be less than or equal to line loss threshold, UE selects a preamble code from groupB; Otherwise UE selects a preamble code from groupA.The mode wherein merging can be for example equal gain combining, high specific merging, selectivity merging etc.
Equal gain combining is for example:
Wherein 0 < G1=G2=...=Gn, further G1=G2=...=Gn < 1, the representative value of Gi can be got Gi=1/n.
High specific merges:
Wherein the relation of Gi and PLi is for example in the time of PL1 < PL2 < PL3... < PLn, G1 > G2 > G3... > Gn > 0.Further, in the time of PL1 < PL2 < PL3... < PLn, 1 > G1 > G2 > G3... > Gn, i.e. the coefficient maximum of minimum PL.
Selectivity merges:
Wherein the value of part Gi is 0.Typical selectivity merges for choosing best circuit loss value, i.e. minimum circuit loss value.For example, PL1 hour, G1=1, G2=G3=...=Gn=0.Or also can be for getting M best circuit loss value.For example, PL1 is M best circuit loss value to PLM,
0 < Gi < 1, wherein the representative value of Gi can be 1.
Circuit loss value is merged, if the circuit loss value after acquisition merges is less than or equal to the line loss threshold of acquisition, illustrate that many up links carry out multiple spot transmitting-receiving and can be equivalent to the transmitting-receiving of the good up link of one or more quality, so can meet the requirement of transmission larger data piece.Therefore, in groupB, select a preamble code to report network side, distribute larger ascending resource to UE with indication network side.
Between the method for above-mentioned various comparisons, can also combine, for example, by two kinds or more of combination the in above-mentioned various comparative approach, form new comparative approach.For example: in all circuit loss value, select maximum circuit loss value, if this path loss is to being less than or being less than or equal to the line loss threshold of obtaining, UE selects a preamble code from groupB; Otherwise, from all circuit loss value, select minimum circuit loss value, if this circuit loss value is less than or is less than or equal to the line loss threshold of obtaining, UE selects a preamble code from groupB, otherwise UE selects a preamble code from groupA.
UE carries the preamble code of selecting in the Random Access Preamble message that sends to network side, with the quality of the comprehensive up link of this UE of indication network side, thereby make network side understand the transmittability of UE up link, distribute corresponding ascending resource.
Pass through the second embodiment of the present invention, UE can be known according to various comparative approach the quality of comprehensive up link, and from the corresponding preamble code character of quality of the comprehensive up link of this UE choose the quality of a preamble code with the comprehensive up link of this UE of indication network side, thereby make network side can understand the transmittability of this UE up link, distribute corresponding ascending resource to this UE.In the situation that ascending resource and UE uplink transmission capabilities match, UE not only can make full use of Internet resources, also can reduce error of transmission or number of retransmissions.
Below in conjunction with accompanying drawing 3, describe the third embodiment of the present invention in detail.The third embodiment of the present invention also provides a kind of method of reporting parameters, and the method comprises:
The specific implementation of step 301 can be with reference to the step 201 in second embodiment of the invention, be from step 201 difference: because the uplink interference level of different AP may be different, and need to consider uplink interference level in considering path loss, so the line loss threshold of different AP may be different.The line loss threshold that also can carry AP in the system message of network side broadcast, because each AP all has oneself line loss threshold, so when network side broadcast line loss threshold, can broadcast all line loss threshold, also can adopt the method for time-division to broadcast above-mentioned line loss threshold simultaneously.
Therefore, UE, in the time receiving the system message of network side broadcast, can obtain the line loss threshold of all or part of AP carrying in this system message.
The specific implementation of step 302 can be with reference to the step 202 in second embodiment of the invention.
The each circuit loss value calculating is corresponding with each line loss threshold respectively.For example, AP1 to UE path loss be PL1, this circuit loss value correspondence the line loss threshold of AP1.In the time carrying out the comparison of circuit loss value and line loss threshold, only more corresponding circuit loss value and line loss threshold.
That is to say, be corresponding circuit loss value and line loss threshold value with respect to circuit loss value and the line loss threshold value of same AP.
Further, if the line loss threshold of all AP is same, also can think that this line loss threshold is the corresponding line loss threshold of each circuit loss value.In following each embodiment, corresponding line loss threshold, with reference to the present embodiment, repeats no more.
Step 303 according to each circuit loss value and corresponding line loss threshold, is chosen a preamble code from corresponding preamble code character.
Different comparative approach between each circuit loss value and corresponding line loss threshold all can be for judging the quality of comprehensive up link of this UE, from represent the preamble code character of this quality, select a preamble code according to the quality of this comprehensive up link again, specific implementation can be with reference to the step 203 in second embodiment of the invention, difference is, in step 203 relatively be the circuit loss value selected and unified line loss threshold, and in step 303 relatively be circuit loss value and the each self-corresponding line loss threshold of these circuit loss value of selecting of selecting.
UE carries the preamble code of selecting in the Random Access Preamble message that sends to network side, with the quality of the comprehensive up link of this UE of indication network side, thereby make network side understand the transmittability of UE up link, distribute corresponding ascending resource.
Pass through the third embodiment of the present invention, UE can be according to the more each circuit loss value of various comparative approach and line loss threshold, to judge the quality of comprehensive up link, and from the corresponding preamble code character of this comprehensive uplink quality choose a preamble code, with the comprehensive up link of this UE of indication network side quality, thereby make network side can know the transmittability of this UE up link, distribute corresponding ascending resource to this UE.In the situation that ascending resource and UE uplink transmission capabilities match, UE not only can make full use of Internet resources, also can reduce error of transmission or number of retransmissions.Meanwhile, third embodiment of the invention has also been considered the factor that between different AP, uplink interference level may be different, has assessed more accurately the comprehensive transmittability of up link, and transmittability is better mated with the resource of distribution.
Below in conjunction with accompanying drawing 4, describe the fourth embodiment of the present invention in detail.The fourth embodiment of the present invention provides a kind of UE, and this UE comprises:
Transceiver module 401, for receiving the system message of network side broadcast, carries the transmitting power of network side and the line loss threshold of AP in this system message, wherein line loss threshold for all AP may be identical may be also different; And for sending and choose the preamble parameter that module 403 is selected to network side, network side is known the quality of the up link of UE by this preamble parameter, thereby be UE distribution ascending resource;
Computing module 402, the transmitting power of the network side carrying for the system message receiving according to transceiver module 401, and the received power of this UE, calculate the circuit loss value from network side to UE;
Choose module 403, the line loss threshold of obtaining for the circuit loss value that calculates according to computing module 402 and transceiver module 401 is chosen preamble code from corresponding preamble code character.
Wherein, computing module 402 is for calculating the circuit loss value of each AP to UE, and concrete computational methods are: the received power of transmitting power-UE of circuit loss value=AP, thereby the circuit loss value of n AP of acquisition.
Wherein, choosing module 403 can determination methods judge circuit loss value and line loss threshold, and from corresponding preamble code character, chooses preamble code according to judged result.
For example, choosing module 403 can be for, and in all circuit loss value, more minimum circuit loss value and the line loss threshold of obtaining if this circuit loss value is less than or is less than or equal to the line loss threshold of obtaining, are chosen a preamble code from groupB; Otherwise from groupA, choose a preamble code.The line loss threshold of wherein obtaining is the line loss threshold that each AP is identical.
