Description

Collaboration method, network and user terminal

Technical field

The present invention relates to communication technical field, relate in particular to a kind of collaboration method, network and user terminal.

Background technology

Along with the development of the communication technology, at Long Term Evolution (Long Term Evolut ion, LTE) in system, although the interference in community is effectively suppressed, but the interference of minizone still exists, simultaneously along with the increase of number of users, the quantity of community also constantly increases and the radius of community has dwindled, make the interference effect of minizone increasing, particularly the throughput of Cell Edge User.

Multipoint cooperative (Coordina ted Multiple Point, CoMP) be advanced Long Term Evolution (Long Term Evolut ion Advanced, LTE-A) a kind of cooperation technology of key in, by suppressing neighbor cell interference, improve the network coverage, community on average and edge throughput to reach.This technology, by share information (comprising schedule information, the user data information etc. of channel condition information, community) between different districts, realizes the cooperation of multiple adjacent cells.Wherein, the basis that CoMP cooperates is channel condition information (Channel State Information, CSI) feedback, base station is that each transmitting node in targeted customer's collaboration set distributes independent channel state information reference signals (Channel State Information Reference Signal, CSI-RS) resource information.User measures the channel information from each launch point according to the CSI-RS of configuration.After the information that user terminal (User Equipment, UE) obtains measuring, channel information is carried out to quantification treatment, change into CSI information and feed back to base station, this is the principal mode of current CSI feedback.

At present, heterogeneous network (Heterogeneous Network, HetNet) is networking under same frequency, comprises macro base station macro and micro-base station pico.In R10, introduced Inter-Cell Interference Coordination (Enhanced Inter-Cell Interference Coor dination, the eICIC) technology strengthening, and in eICIC, the mode that has increased time domain is carried out coordinates interference.In the eICIC of HetNet, in order to coordinate the interference of macro base station macro for micro-base station pico user, adopt almost blank subframe (Almost Blank Subframe, ABS) technology.This know-why is: some ABS subframes of periodic configuration that can be semi-static in the subframe of Macro, in these subframes, meeting reduces downlink transmission power and the liveness of Macro.

But, under existing collaboration mode, conventionally only adopt a kind of CoMP pattern for all cooperation points, this situation can limit the range of application of CoMP conventionally, still has the interference to the outer user of collaboration set, error, the interference of collaboration set to targeted customer of CSI feedback simultaneously; When there is the mixed deployment of multiple back haul link backhaul in HetNet time, be subject to the restriction of backhau l capacity and time delay, signal transmission rate between them is different, in selecting cooperation point, need to consider this species diversity existing between cooperation point, so be not that a cooperation point in collaboration set can be served as in communities all within the scope of certain, thereby affected the scope that participates in cooperation point, these problems are not well solved under existing conditions.

Embodiment

For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.

Collaboration method, network and user terminal that the embodiment of the present invention provides, classify by the cooperation point in the collaboration set to centered by user terminal, cooperation subset of each class cooperation point composition, directly determine the corresponding collaboration mode of each cooperation subset, or determine the corresponding collaboration mode of each cooperation subset according to the feedback information of user terminal, and utilize the cooperation state of the cooperation point in the corresponding collaboration mode control of each cooperation subset cooperation subset, thereby realized, collaboration set is divided into multiple different cooperation subsets, adopt the cooperation point in different collaboration mode control cooperation subsets for the plurality of different cooperation subset, so not only reduce the interference between different collaboration sets, also improve the robustness of cooperation algorithm to CSI feedback error, and in the flexible cooperation mixing under back haul link condition.

The flow chart of the collaboration method that Fig. 1 provides for the embodiment of the present invention one.As shown in the figure, the present embodiment specifically comprises the following steps:

Step 110, network receives the measurement result information that user terminal sends, and determines the collaboration set centered by user terminal according to this measurement result information.Wherein, measurement result information can be for carrying the measurement result information of collaboration set information, can be also monitoring reference signal (Sounding Reference Signal, SRS).

Particularly, when measurement result information is that while carrying the measurement result information of collaboration set information, the collaboration set in collaboration set information is defined as the collaboration set centered by user terminal by network; When measurement result information is while monitoring reference signal, network carries out RRM (Radio Resource Management to this monitoring reference signal SRS respectively by each cooperation point, RRM) measure, thereby obtain RRM information, and determine the collaboration set centered by user terminal.

Collaboration set in this step 110 centered by user terminal can be determined by user terminal, also can be determined by network.The measurement result information sending when user terminal is while carrying the measurement result information of collaboration set information, illustrate that user terminal determined collaboration set, this collaboration set information is exactly the information of the definite collaboration set of user terminal, makes network that the collaboration set in collaboration set information is defined as to the collaboration set centered by user terminal.Network obtains the RRM information of all launch points in network by measuring the monitoring reference signal SRS of user's transmission, determine the collaboration set centered by user terminal according to this RRM information.

Step 120, network is classified to the cooperation point in collaboration set, cooperation subset of each class cooperation point composition.

Particularly, according to the feature of the each cooperation point in collaboration set, collaboration set is divided into multiple cooperation subsets.Such as: according to the distance value of the each cooperation point in collaboration set and user terminal or and user terminal between channel estimating mass value, the cooperation point in collaboration set is divided into cooperation launch point subset and closes closed subset; In the time that the distance value of the cooperation point in collaboration set and user terminal is less than default distance threshold, cooperation point is divided into cooperation launch point subset; In the time that the distance value of the cooperation point in collaboration set and user terminal is not less than default distance threshold, cooperation point is divided into pass closed subset; Or, in the time that the channel estimating mass value between cooperation point and user terminal in collaboration set is greater than default channel estimating quality threshold, cooperation point is divided into cooperation launch point subset; In the time that the channel estimating mass value between cooperation point and user terminal in collaboration set is not more than default channel estimating quality threshold, cooperation point is divided into pass closed subset.

In another embodiment, according to the feature of the each cooperation point in collaboration set, collaboration set is divided into multiple cooperation subsets.Such as: according to the operating state of the cooperation point in collaboration set, comprise the back haul link type of the cooperation point in collaboration set, load, power consumption, disposal ability etc., cooperation point in collaboration set is divided into joint transmission (Joint Transmission, JT) cooperation subset, one or more cooperative schedulings and beam forming (Coordinated Scheduling and Beamforming, CS/CB) cooperation subset, to in collaboration set, there is the connected cooperation point of large capacity low delay back haul link to be divided into JT cooperation subset, other cooperation points are divided into CS/CB cooperation subset.

Describe the process that explanation network is classified to the cooperation point in collaboration set as an example of two kinds of sorting techniques example below in detail:

First, according to the channel condition of the cooperation point in collaboration set, such as, the distance value that this channel status value is cooperation point and user terminal and and user terminal between channel estimating mass value, collaboration set centered by user terminal is divided into two subsets, comprises cooperation launch point subset and close closed subset.

In the time that the distance value of the cooperation point in collaboration set and user terminal is less than default distance threshold, cooperation point is divided into cooperation launch point subset; In the time that the distance value of the cooperation point in collaboration set and user terminal is not less than default distance threshold, cooperation point is divided into pass closed subset; Or, in the time that the channel estimating mass value between cooperation point and user terminal in collaboration set is greater than default channel estimating quality threshold, cooperation point is divided into cooperation launch point subset; In the time that the channel estimating mass value between cooperation point and user terminal in collaboration set is not more than default channel estimating quality threshold, cooperation point is divided into pass closed subset.

Cooperation point in cooperation launch point subset is mainly to subscriber terminal service.And the cooperation point of closing closed subset be the cooperation point that exceedes default threshold value with user terminal distance, the cooperation point distance users terminal that closed subset is closed in this explanation is very far away, and may the user terminal outside collaboration set be produced and be disturbed, so remote cooperation point is divided into and is closed in mute subset.Equally, estimate by channel status, the good cooperation point of channel quality is divided into cooperation launch point subset, and the cooperation point of bad channel quality is divided into and is closed in closed subset.As shown in Figure 2, the collaboration set centered by user terminal 21 comprises cooperation point 31, cooperation point 32, cooperation point 33, cooperation point 34, cooperation point 35, cooperation point 36.According to distance and the channel estimating quality of cooperation point 31, cooperation point 32, cooperation point 33, cooperation point 34, cooperation point 35, cooperation point 36 and user terminal 21, cooperation point 32, cooperation point 33, cooperation point 34 are divided in cooperation launch point subset 11, cooperation point 31, cooperation point 35, cooperation point 36 are divided into and are closed in closed subset 12.Wherein, cooperation point 36 had both belonged to the collaboration set centered by user terminal 21, also belong to the collaboration set centered by user terminal 22, for user terminal 21, the distance of cooperation point 36 distance users terminals 21 is far, also user terminal 22 is produced and disturbed simultaneously, close in closed subset 12 therefore cooperation point 36 must be divided into.In like manner, in the collaboration set centered by user terminal 22, the method for dividing subset is identical with the method for the dividing subset centered by user terminal 21, here repeats no more.

The second, according to being the backhaul situation between cooperation point in collaboration set mixing in backhaul situation, the collaboration set centered by user terminal is divided into two subsets, comprise JT cooperation subset, the CS/CB subset that cooperates.

Mixing under backhaul condition, select the similar cooperation point of backhaul situation to form JT cooperation subset, other cooperation points form CS/CB cooperation subset, distinguish flexibly cooperation point according to the backhaul situation class of cooperation point, collaboration set is divided into each cooperation subset, comprises JT cooperation subset and CS/CB cooperation subset, realized in JT cooperation subset user terminal is done to JT, the cooperation that each JT is cooperated in subset can not be subject to the restriction of backhaul, then between each JT cooperation subset, does CS/CB cooperation.As shown in Figure 3, the collaboration set centered by user terminal 11 comprise cooperation point 21, cooperation point 22, cooperation point 23, cooperation point 24,, cooperation point 25 and cooperation point 26.Collaboration set centered by user terminal 12 also comprise cooperation point 21, cooperation point 22, cooperation point 23, cooperation point 24,, cooperation point 25 and cooperation point 26.

Centered by user terminal 11, choosing the cooperation point of self cooperation is the JT cooperation subset that the similar cooperation point of backhaul 21, cooperation point 22 and cooperation point 23 form user terminal 11, and selecting collaboration point 24, cooperation point 25 and cooperation point 26 form the CS/CB cooperation subset of user terminal 11; And user terminal 12 is centered by self, choosing the cooperation point of self cooperation is the JT cooperation subset that the similar cooperation point of backhaul 24, cooperation point 25 and cooperation point 26 form user terminal 12, and selecting collaboration point 24, cooperation point 25 and cooperation point 26 form the CS/CB cooperation subset of user terminal 12.

Step 130, network is determined the corresponding collaboration mode of each cooperation subset, and utilizes the cooperation state of the cooperation point in the corresponding collaboration mode control cooperation subset of each cooperation subset, thereby is subscriber terminal service.

In one embodiment, in step 130, network can directly be determined the corresponding collaboration mode of each cooperation subset, and utilizes the cooperation state of the cooperation point in the corresponding collaboration mode control cooperation subset of each cooperation subset, thereby is subscriber terminal service.Such as, in the time that collaboration set comprises cooperation launch point subset and closes closed subset, cooperation point in network control control cooperation launch point subset is carried out joint transmission JT or cooperative scheduling and beam forming CS/CB to user terminal, and controls on the running time-frequency resource that the cooperation point of closing in closed subset is scheduled at user terminal and keep mourning in silence.Or in the time that collaboration set comprises JT cooperation subset and CS/CB cooperation subset, the cooperation point in network control JT cooperation subset is carried out JT to user terminal, and control between different CS/CB cooperation subsets and JT cooperation subset and use CS/CB cooperation.

In another embodiment, in step 130, network can also be determined the corresponding collaboration mode of each cooperation subset according to the feedback information of user terminal, and utilize the cooperation state of the cooperation point in the corresponding collaboration mode control of each cooperation subset cooperation subset, thereby be subscriber terminal service.Such as, in the time that collaboration set comprises cooperation launch point subset and closes closed subset, network receive that user terminal sends for the feedback information of the cooperation point in cooperation launch point subset with for the feedback information that closes the cooperation point in closed subset, according to the cooperation point in the feedback information control cooperation launch point subset of the cooperation point in cooperation launch point subset, user terminal is carried out to joint transmission JT or cooperative scheduling and beam forming CS/CB, and keep mourning in silence on the running time-frequency resource being scheduled at user terminal according to the cooperation point in the feedback information control pass closed subset of the cooperation point in the closed subset of pass.Or, in the time that collaboration set comprises JT cooperation subset and CS/CB cooperation subset, network receives the feedback information for the cooperation point in JT cooperation subset that user terminal sends, according to the cooperation point in feedback information control JT cooperation subset, user terminal is carried out to JT, and control between different CS/CB cooperation subsets and JT cooperation subset and use CS/CB cooperation.

Therefore, the collaboration method that the embodiment of the present invention provides, the measurement result information sending by receiving user terminal, determine the collaboration set centered by user terminal according to this measurement result information, and the cooperation point in the collaboration set centered by user terminal is classified, cooperation subset of each class cooperation point composition, directly determine the corresponding collaboration mode of each cooperation subset, or determine the corresponding collaboration mode of each cooperation subset according to the feedback information of user terminal, and utilize the cooperation state of the cooperation point in the corresponding collaboration mode control of each cooperation subset cooperation subset, thereby realized, collaboration set is divided into multiple different cooperation subsets, adopt the cooperation point in different collaboration mode control cooperation subsets for the plurality of different cooperation subset, so not only reduce the interference between different collaboration sets, also improve the robustness of cooperation algorithm to CSI feedback error, and in the flexible cooperation mixing under back haul link condition.

The flow chart of the collaboration method that Fig. 4 provides for the embodiment of the present invention four.As shown in the figure, the present embodiment specifically comprises the following steps:

Step 410, user terminal is measured all launch points in network, and measurement result information is sent to network, and determines the collaboration set centered by user terminal.

Particularly, user terminal is processed the launch point in subzone network, thereby sets up the collaboration set centered by user terminal.Wherein, set up collaboration set centered by user terminal UE be according to user for subzone network in the RRM RRM that carries out of each launch point measure and determine.Difference between the RSRP value of the strongest launch point that the Reference Signal Received Power RSRP value of some launch points and targeted customer measure is less than default threshold value, such as, when a certain certain threshold, think that this launch point belongs to collaboration set.Selected collaboration set is fed back to base station by the result that user measures according to RRM.Network also can obtain similar RRM information by the monitoring reference signal SRS that measures user's transmission simultaneously, directly determines collaboration set at network side.

Describe user terminal in step 410 below in detail the launch point in subzone network is processed, thus the process of the collaboration set of foundation centered by user terminal.

The first, user terminal UE carries out RRM measurement to the each launch point in network, and RRM obtains the Reference Signal Received Power RSRP value of each launch point after measuring.

The second, from the RSRP value of each launch point, choose maximum RSRP value, and calculate the RSRP value of each launch point and the difference of maximum RSRP value.

The 3rd, the difference of each launch point and default threshold value are compared, in the time that the difference of launch point is less than default threshold value, launch point is cooperation point, all cooperation points form the collaboration set centered by user terminal.

The 4th, from cooperation point, selected part or the Reference Signal Received Power RSRP value of whole launch points or the collaboration set centered by user terminal are sent to network as measurement result information.

Step 420, user terminal is classified to the cooperation point in the collaboration set centered by user terminal, cooperation subset of each class cooperation point composition.

Particularly, according to the feature of the each cooperation point in collaboration set, collaboration set is divided into multiple cooperation subsets.Such as, (1) user terminal is according to the channel condition of the cooperation point in collaboration set, such as, according to the distance value of the each cooperation point in collaboration set and user terminal or and user terminal between channel estimating mass value, the cooperation point in the collaboration set centered by user terminal is divided into cooperation launch point subset and closes closed subset; (2) user terminal, according to the operating state of the cooperation point in collaboration set, is divided into joint transmission JT cooperation subset and cooperative scheduling and beam forming CS/CB cooperation subset by the cooperation point in collaboration set; By in collaboration set, have that large capacity low delay back haul link is connected cooperation point be divided into JT cooperation subset, other cooperation points are divided into CS/CB cooperation subset.

Illustrate above-mentioned two kinds of sorting techniques below.

First, user terminal is according to the channel condition of the cooperation point in collaboration set, such as, the distance value that this channel status value is cooperation point and user terminal and and user terminal between channel estimating mass value, collaboration set centered by user terminal is divided into two subsets, comprises cooperation launch point subset and close closed subset.

Cooperation point in cooperation launch point subset is mainly to subscriber terminal service.And the cooperation point of closing closed subset be the cooperation point that exceedes default threshold value with user terminal distance, the cooperation point distance users terminal that closed subset is closed in this explanation is very far away, and may the user terminal outside collaboration set be produced and be disturbed, so remote cooperation point is divided into and is closed in mute subset.Equally, estimate by channel status, the good cooperation point of channel quality is divided into and closes cooperation subset, and the cooperation point of bad channel quality is divided into and is closed in closed subset.As shown in Figure 2, the collaboration set centered by user terminal 21 comprises cooperation point 31, cooperation point 32, cooperation point 33, cooperation point 34, cooperation point 35, cooperation point 36.According to distance and the channel estimating quality of cooperation point 31, cooperation point 32, cooperation point 33, cooperation point 34, cooperation point 35, cooperation point 36 and user terminal 21, cooperation point 32, cooperation point 33, cooperation point 34 are divided in cooperation subset 11, cooperation point 31, cooperation point 35, cooperation point 36 are divided into and are closed in closed subset 12.Wherein, cooperation point 36 had both belonged to the collaboration set centered by user terminal 21, also belong to the collaboration set centered by user terminal 22, for user terminal 21, the distance of cooperation point 36 distance users terminals 21 is far, also user terminal 22 is produced and disturbed simultaneously, close in closed subset 12 therefore cooperation point 36 must be divided into.In like manner, in the collaboration set centered by user terminal 22, the method for dividing subset is identical with the method for the dividing subset centered by user terminal 21, here repeats no more.

The second, user terminal is according to the operating state of the cooperation point in collaboration set, such as, be the backhaul situation between cooperation point in collaboration set mixing in backhaul situation, the collaboration set centered by user terminal is divided into two subsets, comprise JT cooperation subset, the CS/CB subset that cooperates.

User terminal 11 is centered by self, choosing the cooperation point of self cooperation is the JT cooperation subset that the similar cooperation point of backhaul 21, cooperation point 22 and cooperation point 23 form user terminal 11, and selecting collaboration point 24, cooperation point 25 and cooperation point 26 form the CS/CB cooperation subset of user terminal 11; And user terminal 12 is centered by self, choosing the cooperation point of self cooperation is the JT cooperation subset that the similar cooperation point of backhaul 24, cooperation point 25 and cooperation point 26 form user terminal 12, and selecting collaboration point 24, cooperation point 25 and cooperation point 26 form the CS/CB cooperation subset of user terminal 12.

Step 430, user terminal measurement obtains the feedback information corresponding with the subset that cooperates, and feedback information is sent to network, and adopting the collaboration mode corresponding with cooperation subset in order to network according to feedback information is subscriber terminal service.

Illustrate below after above-mentioned two kinds of sorting techniques, user terminal measurement obtains the feedback information corresponding with the subset that cooperates, and feedback information is sent to network, adopt according to feedback information the process that the collaboration mode corresponding with cooperation subset is subscriber terminal service in order to network.

The first, the collaboration set centered by user terminal is divided into cooperation launch point subset and closes closed subset.

For the cooperation point in cooperation launch point subset, measure after the channel information of cooperation point, convert channel information to channel condition information (Channel State Information through quantification treatment, CSI), and channel condition information CSI is fed back to network as the feedback information of the cooperation point in cooperation launch point subset, according to feedback information control cooperation point, user terminal is carried out to joint transmission JT or cooperative scheduling and beam forming CS/CB in order to network; Feedback information also comprises the phase information of cooperation point;

For the cooperation point of closing in closed subset, using the indication information of cooperation point as feeding back to network for the feedback information that closes the cooperation point in closed subset, on the running time-frequency resource being scheduled at user terminal according to the cooperation point in the closed subset of feedback information control pass in order to network, keep mourning in silence.

Particularly, for the each cooperation point in cooperation launch point subset, when user terminal measurement is to the channel information of the cooperation point in launch point subset that cooperates, by this channel information after quantification treatment converts channel condition information CSI information to, this CSI information is fed back to network, and this CSI information can also comprise the phase information of each cooperation point; Network uses the cooperation point in cooperation launch point subset to carry out joint transmission JT or cooperative scheduling and beam forming CS/CB to user terminal.Because the cooperation point in cooperation subset and the distance of user terminal are smaller,, relatively near user terminal, meanwhile, the channel condition between each cooperation point and user terminal is relatively good.Now, if cooperation point is JT or CB/CS to user terminal, by the interference greatly reducing the outer user terminal of this collaboration set.

But, user terminal will not carry out CSI feedback for closing closed subset, and only tell which cooperation point of network is the cooperation point of closing closed subset, and on the running time-frequency resource that the cooperation point of closing closed subset is scheduled at user terminal, keeping mourning in silence, the cooperation point of closing closed subset is not carried out the transmission of data-signal.

The disposal ability of in addition, closing the cooperation point of closed subset can facilitating collaboration subset be carried out data processing.When closing, cooperation point in closed subset is more idle, and point in cooperation subset is slower, can be used to the cooperation point of closing in closed subset, and facilitating collaboration subset is carried out data processing.

The second, the collaboration set centered by user terminal is divided into JT cooperation subset, the CS/CB subset that cooperates.

For the cooperation point of JT cooperation subset, measure after the channel information of cooperation point, convert channel information to channel condition information CSI through quantification treatment, and channel condition information CSI is fed back to network as the feedback information of the cooperation point in JT cooperation subset, according to feedback information control cooperation point, user terminal is carried out to JT in order to network; Feedback information also comprises the phase information between cooperation point in JT cooperation subset;

In the time that JT cooperation subset is carried out CS/CB to CS/CB cooperation subset, channel condition information CSI is fed back to CS/CB cooperation subset, carry out CS/CB cooperation in order to the CS/CB cooperation subset subset that cooperates with JT according to channel condition information CSI.

Particularly, the cooperation point in the JT cooperation subset centered by user terminal is served for user terminal provides JT in this JT cooperation subset.
