Description
Technical field
The present invention relates to communication technical field, particularly a kind of technology of reporting parameters.
Background technology
In existing mobile communications system, (User Equipment UE) before initial initiation business, need carry out a random access procedure to subscriber equipment.By this process, UE reports parameter to network side, so that network side can be known 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 bigger ascending resource of this UE under situation about allowing, and UE can transmit bigger data block; If the uplink quality of opposite UE is relatively poor, then network side distributes less ascending resource can for this UE, and UE can only transmit less data block.
Before UE initiates random access procedure, between UE and the network side also without any connection, so this moment, network side can't obtain the quality of the up link of this UE by the measurement of self, needed UE to inform the quality of this UE up link of network side by the message of uplink.After this, network side can be given UE according to the corresponding resource of the mass distribution of UE up link.Therefore, UE need be with the quality that connects the up link of informing this UE of network side in the access procedure.
UE can (Pathloss, PL) situation be judged the quality good or not of up link to the path loss between the UE according to network side.
Under current system, only there is a up link in point-to-point transmission the between UE and the 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 the quality of UE up link at network side after, the size of ascending resource of this UE is distributed in decision, avoids the UE transmission is bigger when uplink quality is relatively poor data block or the less data block of UE transmission when uplink quality is better.
Under evolution system, UE can be simultaneously from a plurality of access points (Access Point, AP) reception and transmission information.UE is during in the face of a plurality of AP, all has a up link between UE and each AP that can communicate by letter with it, that is to say that UE can receive data from the different AP of different sub-districts or same sub-district, also can be to these AP transmission data.
When having a plurality of AP, what UE can't utilize then that point-to-point transmission adopts reports mode to network side reporting uplink link-quality.Network side also just can't be judged the size of the resource of distributing to subsequent data transmission thus.At this moment, UE may transmit bigger data block when uplink quality is all relatively poor, causes error in data or loses, and perhaps causes data re-transmission; UE also may transmit less data block when uplink quality is all better, cause the wasting of resources.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
In each of the embodiments described below, wireless communication system is an example with the LTE evolution system, but can widespread usage in other wireless communication systems, for example be applied in the LTE system.In each of the embodiments described below, with preamble sign indicating number and random access guiding (Random Access Preamble) message is example, but be not limited to preamble sign indicating number and Random Access Preamble message, those of ordinary skills as can be known, Random Access Preamble message can be other upstream message, and the preamble sign indicating number can be the parameter that can indicate uplink quality of carrying in other the upstream message.
In random access procedure, UE can send Random Access Preamble message to network side, carries the preamble sign indicating number in this message; After network side receives Random Access Preamble message, send accidental access response (Random Access Response) message to UE, indication UE network side is distributed to the resource of this UE in this message; After UE receives Random Access Response message, send scheduling to network side and transmit (Scheduled Transmission) message, can transmit bigger data block in this message and also can transmit less data block.Wherein the preamble sign indicating number is the parameter that is used to indicate the UE uplink quality.
For UE can be by reporting the preamble sign indicating number, the quality of this UE up link of indication network side can be represented different uplink qualities with different preamble sign indicating numbers.But because the preamble sign indicating number may be more, and the quality of indication up link does not need higher precision yet, so the preamble sign indicating number is divided into two groups or many groups partly or completely, every group of preamble sign indicating number represented different uplink qualities.Wherein, the quantity of preamble code character can be according to the precision decision of the required uplink quality of network side.
For example, when preamble sign indicating number 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 sign indicating number of receiving when network side belongs to first group, just can think that the uplink quality of UE is relatively poor, only need to distribute a less ascending resource to get final product; And the preamble sign indicating number of receiving when network side just can think that the uplink quality of UE is better when belonging to second group, can distribute more ascending resource.
Perhaps, when preamble sign indicating number 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 relatively poor, and the uplink quality of the preamble representation UE in second group is general, and the uplink quality of the preamble representation UE in the 3rd group is better.
Therefore, can represent the different quality of up link by dividing several preamble code characters, UE judges the preamble sign indicating number that carry in which preamble code character according to the quality of up link in Random Access Preamble message.Network side also can belong to the quality which code character is known the up link of this UE by judging the preamble sign indicating number that this message is carried, thereby distribute corresponding ascending resource after receiving Random Access Preamble message.
In order to narrate conveniently, following each embodiment is an example so that all preamble sign indicating numbers are divided into 2 preamble code characters all, be respectively groupA and groupB, wherein the preamble representation uplink quality among the groupA is relatively poor, and the preamble representation uplink quality among the groupB is better.The above-mentioned mode that the preamble sign indicating number is divided into groups does not limit the present invention in this packet mode, can also be with impartial or unequal being divided into more than two groups or two groups of preamble sign indicating number partly or completely.
When selecting a preamble sign indicating number in a certain preamble code character, can be selective sequential or select at random, also can be to select according to a set rule, for example for selecting the preamble sign indicating number with the preamble sign indicating number difference minimum of transmission last time.

By first embodiment of the invention, UE can consider according to the quality comprehensive of a plurality of up links, select the preamble sign indicating number to report network side from the corresponding preamble code character that can indicate uplink quality.Thereby make network side to know the quality of the up link of UE, thereby determine to distribute to the ascending resource of this UE by judging the code character that this preamble sign indicating number is belonged to.
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 this method comprises:
UE obtains the transmitting power of the network side that carries in this system message by receiving the system message of network side broadcasting.
Can also carry line loss threshold in system message, 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 among the UE.
UE calculates the path loss of each AP to this UE according to the received power of oneself and the transmitting power of the network side that obtains.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, and is respectively PL1, PL2......PLn.Wherein n is the quantity of AP, and n is the quantity of AP among the following embodiment, repeats no more.
Different comparative approach all can be used to judge the quality of the comprehensive up link of this UE between each circuit loss value and the line loss threshold, selects a preamble sign indicating number according to the quality of this comprehensive up link from the preamble code character of representing this quality again.
For example, compare each circuit loss value and line loss threshold, from corresponding preamble code character, select the preamble sign indicating number, can be: in all circuit loss value, select minimum circuit loss value, if this circuit loss value less than or smaller or equal to the line loss threshold of obtaining, then UE selects a preamble sign indicating number from groupB; Otherwise UE selects a preamble sign indicating number 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 satisfy the requirement of the bigger data block of transmission.Therefore, in groupB, select a preamble sign indicating number to report network side, distribute bigger ascending resource to give UE with the indication network side.
For example, compare each circuit loss value and line loss threshold, from corresponding preamble code character, select the preamble sign indicating number, can also be: in all circuit loss value, select maximum circuit loss value, if this circuit loss value less than or smaller or equal to the line loss threshold of obtaining, then UE selects a preamble sign indicating number from groupB; Otherwise UE selects a preamble sign indicating number 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 satisfy the requirement of the bigger data block of transmission.Therefore, in groupB, select a preamble sign indicating number to report network side, distribute bigger ascending resource to give UE with the indication network side.
For example, compare each circuit loss value and line loss threshold, from corresponding preamble code character, select the preamble sign indicating number, can also be: in all circuit loss value, select M circuit loss value, the method for selecting is the circuit loss value from minimum, and order is selected M circuit loss value from small to large, if the M that picks out circuit loss value all less than or smaller or equal to the line loss threshold of obtaining, then UE selects a preamble sign indicating number from groupB; Otherwise UE selects a preamble sign indicating number from groupA.Wherein, M is greater than 1 and smaller 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 observe jointly by UE and network side, and also can be that UE is self-determining, can also be preset among the UE.Above-mentioned description for the M value also is applicable to following each embodiment.
The M that selects a from small to large circuit loss value is less than or equal to line loss threshold, just illustrates that the quality of the up link of M at least of this UE is better, so can satisfy the requirement of the bigger data block of transmission.Therefore, in groupB, select a preamble sign indicating number to report network side, distribute bigger ascending resource to give UE with the indication network side.
For example, compare each circuit loss value and line loss threshold, from corresponding preamble code character, select the preamble sign indicating number, can also be: in all circuit loss value, select M circuit loss value, the method for selecting is the circuit loss value from maximum, and descending order is selected M circuit loss value, if the M that picks out circuit loss value all greater than or more than or equal to the line loss threshold of obtaining, then UE selects a preamble sign indicating number from groupA; Otherwise UE selects a preamble sign indicating number 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 the up link of M at least of this UE is all relatively poor, so may be difficult to satisfy the requirement of the bigger data block of transmission.Therefore, in groupA, select a preamble sign indicating number to report network side, distribute less ascending resource to give UE with the indication network side.
For example, compare each circuit loss value and line loss threshold, from corresponding preamble code character, select the preamble sign indicating number, 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 that picks out circuit loss value all greater than or more than or equal to the line loss threshold of obtaining, then UE selects a preamble sign indicating number from groupA; Otherwise UE selects a preamble sign indicating number from groupB.
For example, compare each circuit loss value and line loss threshold, from corresponding preamble code character, select the preamble sign indicating number, 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 that picks out circuit loss value all less than in or less than in the line loss threshold that equals to obtain, then UE selects a preamble sign indicating number from groupB; Otherwise UE selects a preamble sign indicating number from groupA.
The M of a random choose circuit loss value all less than or greater than just explanation of line loss threshold, the quality of the up link of M at least of this UE is all better or relatively poor, therefore, from groupB or groupA, select a preamble sign indicating number to report network side accordingly, distribute a bigger or less ascending resource to give UE with the indication network side.
For example, relatively each circuit loss value and line loss threshold are selected the preamble sign indicating number from corresponding preamble code character, and can also be: when satisfying following condition, UE selects a preamble sign indicating number from groupB; Otherwise UE selects a preamble sign indicating number from groupA.The condition that need to satisfy be: smaller or equal to the quantity of the circuit loss value of line loss threshold with greater than the ratio of the quantity of the circuit loss value of line loss threshold more than or equal to X; Or less than the quantity of the circuit loss value of line loss threshold with more than or equal to the ratio of the quantity of the circuit loss value of line loss threshold more than or equal to X; Or greater than the quantity of the circuit loss value of line loss threshold with smaller or equal to the ratio of the quantity of the circuit loss value of line loss threshold smaller or equal to X; Or more than or equal to the quantity of the circuit loss value of line loss threshold with less than the ratio of the quantity of the circuit loss value of line loss threshold smaller or equal to X.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 observe jointly by UE and network side, and also can be that UE is self-determining, can also be preset among the UE.Above-mentioned description for the X value also is applicable to following each embodiment.
In the X value is 1 o'clock, this function corresponding relation can be understood as, more less than the quantity of the circuit loss value of line loss threshold than quantity greater than the circuit loss value of line loss threshold, that is to say, the quality of this UE preferably the quantity of up link more than the quantity of second-rate up link, so can satisfy the requirement of the bigger data block of transmission.Therefore, in groupB, select a preamble sign indicating number to report network side, distribute bigger ascending resource to give UE with the indication network side.
For example, relatively each circuit loss value and line loss threshold are selected the preamble sign indicating number from corresponding preamble code character, can also be: all circuit loss value are merged, if the circuit loss value PLmerger after merging
Less than or smaller or equal to line loss threshold, then UE selects a preamble sign indicating number from groupB; Otherwise UE selects a preamble sign indicating number from groupA.Wherein the mode of He Binging for example can be equal gain combining, high specific merging, selectivity merging etc.
Equal gain combining for example is:
0＜G1=G2=...=Gn wherein, 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 for when PL1＜PL2＜PL3...＜PLn, G1＞G2＞G3...＞Gn＞0.Further, when PL1＜PL2＜PL3...＜PLn, 1＞G1＞G2＞G3...＞Gn, i.e. the coefficient maximum of Zui Xiao PL.
Selectivity merges:
Wherein the value of part Gi is 0.Typical selectivity merges for choosing best circuit loss value, i.e. Zui Xiao circuit loss value.For example, PL1 hour, G1=1, G2=G3=...=Gn=0.Perhaps also can be for getting M best circuit loss value.For example, PL1 is a M best circuit loss value to PLM, then
0＜Gi＜1, wherein the representative value of Gi can be 1.
Circuit loss value is merged, if the circuit loss value after obtaining to merge is less than or equal to the line loss threshold of acquisition, illustrate that then many up links carry out multiple spot transmitting-receiving and can be equivalent to the transmitting-receiving of up link preferably of one or more quality, so can satisfy the requirement of transmission larger data piece.Therefore, in groupB, select a preamble sign indicating number to report network side, distribute bigger ascending resource to give UE with the indication network side.
Can also make up between the method for above-mentioned various comparisons,, form new comparative approach for example with two kinds or more of combination the in the above-mentioned various comparative approach.For example: in all circuit loss value, select maximum circuit loss value, if this path loss to less than or smaller or equal to the line loss threshold of obtaining, then UE selects a preamble sign indicating number from groupB; Otherwise, from all circuit loss value, select minimum circuit loss value, if this circuit loss value less than or smaller or equal to the line loss threshold of obtaining, then UE selects a preamble sign indicating number from groupB, otherwise UE selects a preamble sign indicating number from groupA.
Step 204 sends to network side with the preamble sign indicating number of selecting.
UE carries the preamble sign indicating number of selecting in sending to the Random Access Preamble message of network side, quality with 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 the quality of comprehensive up link according to various comparative approach, and from the corresponding preamble code character of quality of the comprehensive up link of this UE choose the quality of a preamble sign indicating number 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 give this UE.Under the situation that ascending resource and UE uplink transmission capabilities are complementary, 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 this method comprises:
Step 301 is obtained transmitting power and line loss threshold.
The specific implementation of step 301 can be with reference to the step 201 in the second embodiment of the invention, be with step 201 difference: because the uplink interference level of different AP may be different, and need consider uplink interference level when considering path loss, so the line loss threshold of different AP may be different.The line loss threshold that in the system message of network side broadcasting, also can carry AP, because each AP all has the line loss threshold of oneself, so during network side broadcasting line loss threshold, can broadcast all line loss threshold simultaneously, also can adopt the method for time-division to broadcast above-mentioned line loss threshold.
Therefore, UE can obtain the line loss threshold of all or part of AP that carries in this system message when receiving the system message of network side broadcasting.
Step 302 is calculated the path loss of each AP to UE.
The specific implementation of step 302 can be with reference to the step 202 in the second embodiment of the invention.
Each circuit loss value that calculates 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.When carrying out the comparison of circuit loss value and line loss threshold, only relatively 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 the circuit loss value of same AP and line loss threshold value.
Further, if the line loss threshold of all AP is same, can think also that then this line loss threshold is the line loss threshold of the correspondence of each circuit loss value.Among following each embodiment, corresponding line loss threshold repeats no more with reference to present embodiment.
Step 303 according to each circuit loss value and corresponding line loss threshold, is chosen a preamble sign indicating number from corresponding preamble code character.
Each circuit loss value and different comparative approach between the corresponding line loss threshold all can be used to judge the quality of the comprehensive up link of this UE, from the preamble code character of representing this quality, select a preamble sign indicating number according to the quality of this comprehensive up link again, specific implementation can be with reference to the step 203 in the second embodiment of the invention, difference is, in the step 203 relatively be the circuit loss value selected and unified line loss threshold, and in the step 303 relatively be circuit loss value and each self-corresponding line loss threshold of these circuit loss value of selecting of selecting.
Step 304 sends to network side with the preamble sign indicating number of selecting.
UE carries the preamble sign indicating number of selecting in sending to the Random Access Preamble message of network side, quality with 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 compare each circuit loss value and line loss threshold according to various comparative approach, to judge the quality of comprehensive up link, and from the corresponding preamble code character of this comprehensive uplink quality choose a preamble sign indicating number, 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 give this UE.Under the situation that ascending resource and UE uplink transmission capabilities are complementary, UE not only can make full use of Internet resources, also can reduce error of transmission or number of retransmissions.Simultaneously, third embodiment of the invention has also been considered the factor that uplink interference level may be different between the different AP, has assessed the comprehensive transmittability of up link more accurately, the resource better matching that makes transmittability and 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:
Choose module 403, be used for the line loss threshold that the circuit loss value that calculates according to computing module 402 and transceiver module 401 obtain and choose the preamble sign indicating number from corresponding preamble code character.
Wherein, computing module 402 is used to calculate 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, choose module 403 and can determination methods judge circuit loss value and line loss threshold, and from corresponding preamble code character, choose the preamble sign indicating number according to judged result.
For example, choosing module 403 can be used for, in all circuit loss value, relatively more minimum circuit loss value and the line loss threshold of obtaining, if this circuit loss value less than or smaller or equal to the line loss threshold of obtaining, then from groupB, choose a preamble sign indicating number; Otherwise from groupA, choose a preamble sign indicating number.The line loss threshold of wherein obtaining is the identical line loss threshold of each AP.
For example, choosing module 403 can also be used for, and in all circuit loss value, relatively more maximum circuit loss value and the line loss threshold of obtaining if this circuit loss value is less than or equal to the line loss threshold of obtaining, are then chosen a preamble sign indicating number from groupB; Otherwise from groupA, choose a preamble sign indicating number.The line loss threshold of wherein obtaining is the identical line loss threshold of each AP.
