Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
In a first aspect, the embodiment of the invention provides the acquisition methods of the channel quality identification CQI of shared channel a kind of, ginseng
See Fig. 1, comprising:
S101, group's group configuration message is broadcasted to the colony terminal of broadband cluster system Zhong Ge group, group's group configuration message is used
In the group identification G-RNTI for indicating each group, it is also used to be designated as reporting for colony terminal in group for each group allocation
The PUCCH channel resource of the measurement feedback information of channel is shared by the group；
S102, the measurement feedback information that colony terminal reports on corresponding channel resource is received, measured in feedback information
Group identification G-RNTI and the group comprising the colony terminal group share the CQI of channel.
In the acquisition methods of shared channel CQI provided in an embodiment of the present invention, network side equipment (such as base station) can be to
The colony terminal of broadband cluster system Zhong Ge group broadcasts group's group configuration message, this group of group configuration messages can indicate group identification
G-RNTI also can indicate that as the group allocation for reporting the PUCCH channel resource of shared channel measurement feedback information.Group
Colony terminal in group when needed can on specified channel reporting measurement feedback information, so that network side equipment is by connecing
The CQI that channel is shared by the group can be obtained by receiving measurement feedback information.Method provided in an embodiment of the present invention is based on group
Carry out PUCCH resource distribution, thus will not due in group terminal it is too many and the case where occur point less than resource, furthermore cluster
CQI report and be all based on group identification to report, the CQI that multiple terminals report is equal to the same end for network side
The CQI at end, therefore network side not will increase excessive processing load, and then network side equipment can share channel according to group
The shared channel of the group is adaptively adjusted in CQI.
Wherein, colony terminal here its be substantially also common terminal, only the terminal attaching is small at one
In a group under area.Here group's group configuration message is that network side equipment issues when group establishes.Here G-
RNTI is that similar (Cell Radio Network Temporary Identifier, cell-radio network face with C-RNTI in fact
When identify).C-RNTI distributes to a dynamic marks of UE by network side equipment, under one cell of unique identification is eated dishes without rice or wine
UE, the only UE under connected state, C-RNTI are just effective.And G-RNTI is Group Radio Network Temporary
Identifier namely group's radio network temporary identifier and network side equipment distribute to a dynamic marks of group, only
One identifies a group under a cell is eated dishes without rice or wine.
Understandable to be, the foundation of group and release are all set according to the actual situation.Therefore the present invention is real
The method that example offer is provided further include: be directed to each group, after determining group release, be recovered as the PUCCH letter of its distribution
Road resource.To which reallocation can be recovered to it for the PUCCH channel resource of the group allocation before after group release
His group, the case where avoiding the occurrence of channel resource waste.
It in the specific implementation, can also be to the cluster of each group other than broadcasting group configuration information to colony terminal
Terminal broadcast clustered paging signaling and/or cluster multi call configuration signal.Wherein, clustered paging signaling may include in the group
Colony terminal reports the thresholding that reports of shared channel CQI, and cluster multi call configuration signal may include the colony terminal in the group
Report the report cycle of shared channel CQI.Thresholding will be reported to be handed down to after colony terminal, colony terminal can be according to this
The requirement of thresholding is reported, such as is just reported when CQI is lower than this thresholding.Report cycle is handed down to colony terminal
Later, colony terminal can this report cycle reported.Certainly report thresholding and report cycle here can also be with
Do not issue by base station or only issue a portion.What the parameter not issued can be appointed for base station with terminal in advance, this hair
Bright embodiment is not especially limited this.
Further, since trunked base station is to be allocated the PUCCH resource that CQI is reported for group, it is equivalent to same
Terminal under group carries out shared PUCCH channel, and there may be multiple colony terminals in group to report simultaneously in less situation
Cause trunked base station that cannot normally parse CQI, so that the downlink reception quality of cell edge colony terminal cannot be improved.For this purpose,
CQI report cycle can be further divided into multiple subcycles by network side equipment, and the information of this subcycle is issued to
Colony terminal.It is reported, is passed through to need the colony terminal reported that some subcycle can be randomly selected in large period
Randomization, which reports, to be avoided conflicting.
Understandable to be, it is in order to preferably share to each group that base station, which obtains cluster to share the CQI of channel,
Channel is regulated and controled.The CQI of channel is shared since cluster can not be obtained in the prior art, and then cluster is shared channel and also do not required
Colony terminal carries out CQI feedback, and trunked base station uses fixed modulating-coding format for the downlink shared service channel of cluster,
However the problem of bringing in this way, is:
If 1, channel quality is relatively good, lower modulating-coding format is used, the transmission rate of base station is limited；
2, using lower MCS, the data that will lead to transmission equal length need more PRB, result in interface-free resources
Waste；The group for causing system that can accommodate exhales capacity limited；
3, using higher MCS, the reception that will lead to part colony terminal is poor.
Therefore, method provided in an embodiment of the present invention obtain group share channel CQI on the basis of, can also wrap
It includes:
S103, it is directed to each group, if the measurement feedback information of the group is received in preset time period, according to survey
Measure the CQI calculating target MCS level that channel is shared by the group in feedback information, wherein target MCS level is corresponding with CQI
MCS rank；
If S104, target MCS level the MCS rank current lower than the shared channel of group, reduce being total to for group at once
Enjoy channel MCS rank；If the target MCS level MCS rank current higher than the shared channel of group, after waiting preset time period
The shared channel MCS rank of group is improved again；Wherein, the duration of preset time period here reports shared letter greater than colony terminal
Road CQI report cycle.
That is method provided in an embodiment of the present invention can share the CQI of channel according to the group received to calculate
It can satisfy the suitable target MCS level of its demand, and the rank calculated according to this shares the current group
The MCS rank of channel is adjusted.If current MCS rank is higher compared with target MCS level, illustrate by it is current this
One rank can be poor come the channel received quality of some terminals if carrying out coded modulation, in fact it could happen that not the case where not receiving,
It just needs to reduce MCS rank in time at this time.If MCS rank is relatively low compared with target MCS level, illustrate current MCS
Although rank can satisfy enables all terminals in group to normally receive, it is also possible to continue to improve so as to abundant
Utilization bandwidth resources so that the data more transmitted in the unit time are more, therefore adjusted again after a period of time such as needing at this time
High MCS rank.
It certainly, can also be according to reception CQI's other than adjusting MCS according to the shared channel CQI of the group received
Situation adjusts.Due to colony terminal report group share channel CQI may have the limitation for reporting thresholding, be not less than this door
Limit will not report, it would be possible that one if the CQI that terminals all in this group detect is not less than thresholding
Base station is the measurement feedback information that will not be received any terminal of the group and report in a report cycle.In this case,
Method provided in an embodiment of the present invention further include:
S105, it is improved for each group if not receiving the measurement feedback information of the group in preset time period
The shared channel MCS rank of group.
Specifically, when group establishes, in order to guarantee that all terminals can receive group configuration information, therefore
That initially use is lower MCS, is properly termed as initial MCS.It later after a period of time has passed, can be if without reporting
It is improved on the basis of initial MCS rank.Every raising level-one, needs to wait for a period of time, if do not had still in this period
It reports, then improves MCS rank step by step.
While being adjusted to MCS rank, method provided in an embodiment of the present invention further include:
S106, when the shared channel MCS rank to the group is adjusted, adjust group's colony terminal report altogether
That enjoys channel CQI reports thresholding；
Wherein CQI reports thresholding to increase in company with the raising of MCS rank here, reduces in company with the reduction of MCS rank,
Can be not completely equivalent, but variation tendency can be it is the same.
It is S107, each cluster adjusted for reporting thresholding to carry in clustered paging signaling and broadcasting to the group is whole
End.
The embodiment of the present invention can carry out dynamic adjustment based on the cluster CQI that terminal reports by the method for above-mentioned adjustment.
This method is in more satisfactory situation if colony terminal can be modulated all in the center of cell using highest MCS
Coding, to greatly improve the utilization rate of limited frequency band；In worst case, at least there is a cluster user in cell
Edge just can be modulated coding using minimum MCS, and the MCS for solving cluster DSCH Downlink Shared Channel so is adaptively adjusted
Problem.
It should be noted that may have multiple groups in the overlay area of a base station, in the side that present example provides
Base station is independent of each other for the adjustment control of each group within the scope of its independently of each other in method.
In order to realize method provided in an embodiment of the present invention, it is necessary to be repaired to existing cluster informational message of eating dishes without rice or wine
Change, cluster space interface signaling message can be designed with following codes, since Jie has been carried out in thought of its design in front
It continues, details are not described herein
Second aspect, the embodiment of the invention also provides a kind of report methods of shared channel CQI, referring to fig. 2, comprising:
S201, the group configuration information that network side equipment issues is received, group's group configuration message is used to indicate each group
Group identification G-RNTI, be also used to be designated as each group allocation reports the group to share channel for colony terminal in group
Measure the PUCCH channel resource of feedback information；
S202, meet impose a condition when, the reporting measurement feedback letter on the PUCCH channel resource for affiliated group allocation
Breath, measurement feedback information include the group identification G-RNTI of affiliated group, and channel is shared by the also affiliated group comprising measuring
CQI；Wherein, it imposes a condition as the MCS rank based on current shared channel, the number for not normally receiving data is more than to preset
Value.
In the report method of shared channel CQI provided in an embodiment of the present invention, the instruction group that network side issues is received first
The group configuration information of group mark G-RNTI and the PUCCH channel resource of distribution, then in the number for not normally receiving data
When more than preset value namely when channel received quality is poor, report the mark of group and group total on specified channel resource
Channel is enjoyed, so as to so that the case where network side can know the shared channel of this group based on group identification, and is carried out
Further adjustment, channel is adequately utilized in the case where not increasing load of base station and guaranteeing that each terminal can normally receive
Resource.
It should be noted that preset value here is arranged according to the actual conditions of each group.It is pre- that this is set
If the purpose of value is to allow each terminal in group can be according to the channel received quality of this criterion oneself.To
Second-rate terminal can be picked out, CQI is reported by this poor terminal, so that network side equipment is to the group
The shared channel of group can be compatible with channel in group when being adjusted and receive worst colony terminal, both avoid so numerous
CQI storm caused by CQI is reported, position network side equipment add more loads, and can guarantee that each terminal can after adjusting
It is good to receive.
In the specific implementation, terminal is reported CQI to need to meet setting condition other than including above-mentioned condition, it is also possible to be wrapped
Include: the CQI that channel is shared by the affiliated group measured reports thresholding lower than shared channel CQI.Pass through the setting energy of this thresholding
It enough avoids the passable terminal of some channel received qualities from carrying out meaningless CQI to report, reduces the occupancy meaningless to channel resource.
Wherein, the thresholding that reports here can be the preset thresholding for reporting thresholding namely base station and terminal to appoint in advance, can also be with
To be that group configuration reports thresholding by receiving the network side equipment that the clustered paging signaling that issues of network side equipment obtains,
Can also be terminal reports thresholding and to obtain from network side equipment be that the two for reporting thresholding of its configuration takes for preset
It is small it is obtained report thresholding, this reports the selection of thresholding that can carry out Adaptive selection according to the actual situation, the present invention
Embodiment is not especially limited this.
In the specific implementation, setting condition here can also include: to listen to network side equipment to the collection of affiliated group
The group paging of group terminal is requested.Namely it listens to this group and calls for asking and can be used as colony terminal group is reported to share channel
One in the trigger condition of CQI.
In addition, in the specific implementation, setting condition here can also include: currently have reached shared channel CQI upper
Report the period；Wherein, report cycle here is preset report cycle, or the cluster multi call issued by receiving network side equipment
The network side equipment that configuration signal obtains is the report cycle of group configuration.That is reaching report cycle is also likely to be
Colony terminal reports group to share one in the trigger condition of channel CQI.As described in the text, may go out in less situation
The case where existing multiple colony terminals report simultaneously, causes base station that can not normally parse CQI, base station can be by CQI report cycle at this time
It is divided into multiple subcycles and is issued to colony terminal.It is carried out to which a subcycle can be randomly selected in each colony terminal
Report is reported by randomization and avoids conflicting.In addition to this, if colony terminal be more than N number of large period downlink reception quality still not
It can improve, illustrate that information that this colony terminal reports may receive the interference base stations of other factors and can not normally parse, then
At this time the colony terminal can initiating random access procedure, report CQI and G-RNTI in Msg3 in the random access procedure, be not difficult
Understand be that the information base that Msg3 is reported can be properly received and parse, in Msg3 carry CQI and G-RNTI to
It can be avoided the interference of other factors.
It should be noted that here report that thresholding, monitoring group are exhaled and report cycle these trigger thresholds can be simultaneously
In the presence of one or more can also be only existed, this can be determined according to the actual situation.Such as it when listening to group and exhaling and measures
CQI lower than being reported when reporting thresholding, or reach report cycle and the CQI that measures is reported lower than when reporting thresholding, the present invention
Embodiment is not especially limited this.
It gives the correct time upper, in addition to meet above-mentioned setting condition, in the specific implementation, may also see that the terminal is current
RRC state.Specifically:
It (1), can be direct if terminal is in RRC connected state and is carrying out group-calling service when meeting setting condition
The G-RNTI reporting measurement feedback information for exhaling gambling to win by group.
(2) when meeting setting condition, if terminal is in RRC Idle state and is carrying out group-calling service, to network side
Equipment initiates random access request；After obtaining uplink synchronous in the RAR message issued by network side equipment, termination connects at random
Enter process, namely only need to obtain uplink synchronous in RAR, without entering connected unit；Then for affiliated group allocation
PUCCH channel resource on reporting measurement feedback information.
In addition, as described in the text, the foundation of group and release are all set according to the actual situation.Therefore this hair
The method that bright embodiment provides further include: after the release of the group belonging to determining, stop the survey to the shared channel CQI of the group
Amount, and stop to network side equipment reporting measurement feedback information.
