Embodiment
Below in conjunction with the drawings and specific embodiments, further specify the present invention.
The principle of the invention can be summarized as: utilize the frequency soft multiplexing technology, in frequency duplex factor as one is 1 multi-carrier communications systems, the present invention divides into groups the frequency resource allocation of shared control channel in the same sub-district to different control signalings in, the line ordering of going forward side by side, thereby can effectively manage different user in the sub-district according to actual conditions, determine the order of priority of resource allocation, the user that allowing needs obtains the higher resource of priority ratio.Because the primary importance carrier frequency difference of each sub-district shared control channel, thereby be beneficial to the optimization of communication environment between neighbor cell, improve each user's control channel demodulation performance of sub-district.
For frequency soft multiplexing, its method is: when transmitting the control signaling of shared control channel, the multiplexing factor 1 of inner reserve frequency in the sub-district is then planned the interference that reduces between the sub-district by the frequency grouping at cell boarder, improves the communication quality and the spectrum efficiency of cell boarder.Concrete way is: all frequency resources are divided into the N group, each cell selecting one group of basic frequency resource wherein as this sub-district, other frequencies are provided with different transmitting power thresholdings to basic frequency resource and side frequency resource respectively as the side frequency resource of this sub-district.Usually, the transmitting power thresholding of basic frequency resource is higher than the transmitting power thresholding of side frequency resource.To the cell boundary users group, give the sub-district other user's groups the side frequency resource allocation basic frequency resource allocation.
Consult Fig. 2, multi-carrier communications systems shared control channel resource application process of the present invention is to adopt the mode of adjusting frequency, and its specific implementation process is:
A, the control signaling of sub-district different user is divided at least two groups, and the frequency resource of shared control channel is divided at least two frequency resource block, frequency resource block is sorted in certain sequence the frequency resource block of putting of making number one and the frequency resource block quadrature that makes number one and put of adjacent at least one sub-district.
B, be frequency resource block transmission of each control signaling set of dispense.
Below will introduce in detail:
Among the present invention, described control signaling comprises uplink and downlink control signaling.
The base station by to receive from each user uplink pilot frequency signal, control signal, or the power of data-signal measures, and judges the position of user in the sub-district, as cell boarder or center of housing estate etc.
As previously mentioned, the control signaling of community user can be divided into a plurality of control signaling groups further according to the transmit power needs or the modulating-coding demand that guarantee control signal demodulation performance.The principle of grouping can be to divide into groups according to transmit power needs, promptly delimit different transmitting power scopes earlier, assurance is determined according to the channel condition information of user feedback in the base station, and it controls the transmitting power of signal demodulation performance, and the user who is in same transmitting power scope controls signaling and is divided into one group; Also can promptly determine different modulation coding mode combinations (as QPSK 1/2 code check, QPSK 1/3 code check, BPSK 1/2 code check etc.) earlier according to the grouping of modulating-coding demand.Assurance is determined according to the channel condition information of user feedback in the base station, and it controls the signaling modulation coding mode of signal demodulation performance, and the user of identical modulation coding mode controls signaling and is divided into one group.What note is that grouping is to change according to the variation of actual conditions.In addition, when the number of control signaling group is less than the number of frequency resource block, the frequency resource block of the described primary importance of priority allocation.
Grouping the time can be carried out the frequency resource of shared control channel and divides, and ready-portioned frequency resource block is assigned to and respectively controls the signaling grouping, and carries out from high to low prioritization by the height of transmitting power.
When dividing into groups according to transmitting power, the modulation coding mode that adopts in each group can be different.For example, the modulation coding mode that satisfies the poorest user's of the interior channel condition of group control signal demodulation performance is controlled the modulation coding mode of signaling group as this.
When dividing into groups according to modulation coding mode, the transmitting power that adopts in each group can be different.For example, the transmitting power that satisfies the poorest user's of the interior channel condition of group control signal demodulation performance is controlled the transmitting power of signaling group as this.
For an example, in same sub-district, distribute the primary importance frequency resource, and make its transmitting power be higher than the transmitting power of other frequency resource control signaling groups to cell boundary users control signaling group.The setting of the concrete transmitting power that exceeds can accurate complete received signal be a foundation with cell boundary users.Be the transmitting power that sets in advance control signaling group in the present embodiment, still, also can adjust transmitting power according to its geographic location or certain time interval.
Further, the control signaling of different user in each control signaling grouping is carried out the combined coding modulation,, save the communication resource to reduce the signaling amount that needs transmission greatly.Combined coding is modulated the data block of control signaling composition that refers to all users and is encoded, and uses identical modulation system.Present embodiment is the modulation coding mode that preestablishes different control signaling groups, but also can adjust according to certain time interval.
Described frequency resource block is continuous or discrete subband.Each frequency resource block setting is changeless.Then can adjust according to certain time interval as shown in Figure 5 in other embodiments.Wherein, staggered grid grid is represented shared control channel primary importance frequency resource, and the grey grid is represented other frequency resources of shared control channel, and certainly, these Resource Block are according to packet sequencing.The shared control channel primary importance frequency resource that can find out neighbor cell A, B, C among the figure intermeshes, and its interference of control signaling of receiving of neighbor cell boundary user significantly reduces like this.Other frequency resources of the shared control channel of neighbor cell A, B, C can be overlapping, because the user who uses these frequency resources is in inside, sub-district, the power of launching these power ratio of controlling signalings emission cell boarder control signalings is low, therefore from the region and on the power, all distinguish, reach and reduce the purpose of disturbing and saving resource.
Being provided with of each frequency resource block can arbitrarily be adjusted, as long as neighbor cell shared control channel primary importance frequency resource quadrature in guaranteeing at one time.Specific to present embodiment, be that the primary importance frequency resource of cell boarder shared control channel of neighbor cell is different.For example, 6 frequency resources are arranged, respective identification is respectively 1,2,3,4,5 and 6, in a period of time, the frequency resource that is designated 1 and 2 is divided into one group, the frequency resource that is designated 3 and 5 is divided into one group, the frequency resource that is designated 4 is divided into one group, the frequency resource that is designated 6 is divided into one group, sub-district a is to be designated this class frequency resource of 1 and 2 primary importance frequency resource as this sub-district, all the other frequency resources are distributed by priority, and each group control signaling is carried out combined coding.Neighbor cell b is to be designated this group subcarrier of 4 as the primary importance frequency resource of this sub-district, and all the other frequency resources are distributed by priority; After a period of time, these 5 frequency resources can be divided into groups again, the frequency resource that is designated 2 and 5 is divided into one group, the frequency resource that is designated 4 and 6 is divided into one group, the frequency resource that is designated 1 is divided into one group, the frequency resource that is designated 3 is divided into one group, sub-district a is to be designated this class frequency resource of 4 and 6 primary importance frequency resource as this sub-district, neighbor cell b is to be designated this class frequency resource of 3 primary importance frequency resource as this sub-district, by that analogy.
In like manner, the associating modulation coding mode of different control signaling groups can carry out similarly adjusting with above-mentioned principle according to certain time interval.
Because the transmission of control signaling is a key link in the communication service, the present invention divides into groups the frequency resource allocation of shared control channel in the same sub-district to different control signalings in, the line ordering of going forward side by side, thereby can effectively manage different user in the sub-district according to actual conditions, determine the order of priority of resource allocation, the user that allowing needs obtains the higher resource of priority ratio.Such as carrying out the power control of corresponding different grouping flexibly, improve the control channel demodulation performance, perhaps the code modulation mode to grouping designs, with the accuracy that guarantees that the user receives.Because the primary importance frequency resource block quadrature in the neighbor cell, thereby the signal that can effectively reduce neighbor cell disturbs, be beneficial to the optimization of communication environment between neighbor cell, improve each user's control channel demodulation performance of sub-district, promptly guaranteed effectively carrying out of subsequent communications business.
Further the control signaling of different user in each control signaling grouping is carried out the combined coding modulation,, save the communication resource, satisfy different each user group's needs simultaneously again to reduce the signaling amount that needs transmission greatly.In the above-described embodiment, the distance that user and base station also can be set is used at least two frequency resource block in setting range the time simultaneously, realizes the transmission of high-speed data and multimedia service.
The present invention uses the soft multiplexing method of said frequencies, obtains preferable transmission speed and reduces channel disturbance simultaneously.Be to realize the inventive method, designed a kind of multi-carrier communications systems shared control channel resource multiplex system.Consult Fig. 3, described system 20 is arranged in the base station 10, comprises control signaling transmission control module 21, control signaling grouping module 22, customer location measurement 24, control signal generation module 23 and shared control channel resource division module 26.
Shared control channel resource division module 26 is divided at least two by the frequency resource block that sorts in certain sequence with the frequency resource of shared control channel, and makes the primary importance frequency resource block quadrature in the neighbor cell.
Control signaling transmission control module 21 at first determines to satisfy control signaling modulation coding mode and the transmitting power that the user controls the signal demodulation performance requirement according to the channel condition information of user's 25 feedbacks.As adopting QPSK 1/2 code check according to different channel statuss, QPSK 1/3 code check or BPSK 1/2 code check etc. carries out coded modulation.For the more region of the more signal absorption of barrier, strengthen transmitting power.Guarantee simultaneously that in same sub-district the transmitting power of cell boundary users control signaling group is higher than the transmitting power of side frequency resource control signaling group.In addition, can carry out the combined coding modulation to the control signaling of different user in the same control signaling group, to reduce the signaling amount that needs transmission.Can preestablish the modulation coding mode of different control signaling groups, or adjust, to adapt to the variation of communication environment according to certain time interval.
The upward signal power that the user 25 that customer location measurement module 24 receives by measurement sends is determined user 25 geographic locations.As determining that user 25 is positioned at cell boarder or other positions.
Control signaling grouping module 22 is divided at least two groups with community user, is divided into one group such as the control signaling of boundary user, and other positions, sub-district user's control signaling is divided into one or more groups.And be that frequency resource block of each control signaling set of dispense is transmitted.When the number of control signaling group is less than the number of frequency resource block, the frequency resource block of the described primary importance of priority allocation.
The principle of grouping can be divided into groups to the control signaling of different user according to modulation coding mode/transmission power information and user geographic location information that each user controls signaling.Delimit different transmitting power scopes earlier, assurance is determined according to the channel condition information of user feedback in base station 10, and it controls the transmitting power of signal demodulation performance, and the user who is in same transmitting power scope controls signaling and is divided into one group.
When dividing into groups, the modulation coding mode that satisfies the poorest user's of the interior channel condition of group control signal demodulation performance is controlled the modulation coding mode of signaling group as this according to transmitting power; When dividing into groups according to modulation coding mode, the transmitting power that satisfies the poorest user's of the interior channel condition of group control signal demodulation performance is controlled the transmitting power of signaling group as this, guarantee that with this all users can both accurately receive the control signaling, normal communication service is launched.
In one embodiment, control signaling after 23 pairs of groupings of control signal generation module is carried out modulating-coding and the control signaling group behind the modulating-coding is mapped on each frequency resource block that shared control channel resource division module 26 determines, modulation generates control signal through OFDM again, and by antenna 27, adopt primary importance frequency resource emission control signaling group to cell boundary users, adopt other priority frequency resources to send control signaling and organize other users of this sub-district.
To the power control of each group control signaling, can set in advance the transmitting power of control signaling group, or adjust at a certain time interval according to the channel condition of feedback.
More than, because design control signaling transmission control module 21 and shared control channel resource division module 26 and control signaling grouping module 22, with the frequency resource allocation of shared control channel in the same sub-district in different control signaling groupings, the line ordering of going forward side by side, thereby can effectively manage different user in the sub-district according to actual conditions, determine the order of priority of resource allocation, the user that allowing needs obtains the higher resource of priority ratio, realizes telecommunication management flexibly.Reduce cell boundary users control signaling simultaneously and be subjected to the neighbor cell interference possibility, improve the accuracy of community user control signal demodulation, promptly guaranteed effectively carrying out of subsequent communications business.
