Description
Technical field
The present embodiments relate to fields of communication technology, and in particular to the distribution side of ascending resource in a kind of small bandwidth system
Method and device.
Background technique
In LTE system, Physical Uplink Control Channel (Physical Uplink Control Channel, PUCCH) is used
In carrying uplink control information, uplink L1/L2 control information (Uplink Control Information, UCI) includes:
Uplink scheduling request (Scheduling Req, SR): terminal is used for base station requests uplink UL-SCH resource；
Hybrid automatic repeat-request confirmation/not confirmation message (Hybrid Automatic Repeat reQuest, HARQ)
ACK/NACK: to what is sent on Physical Downlink Shared Channel (Physical Downlink Share Channel, PDSCH)
Downlink data carries out HARQ confirmation；
Channel state information (Channel State Information, CSI): including channel quality information instruction CQI,
The information such as pre-coding matrix instruction PMI, order instruction RI, for telling base station down channel quality etc., to help base station to carry out down
Row scheduling.CSI, which is reported, can be configured to periodically, also can be configured to acyclic.
PUCCH is commonly configured to positioned at the edge of up-link bandwidth on frequency domain, and a PUCCH is in uplink
2 time slots are accounted in frame, each time slot accounts for 12 subcarriers, i.e. 1 resource block (Resource Block, RB) on frequency domain.For
Offer frequency diversity, boundary frequency hopping of the PUCCH in time slot: i.e. in same subframe, the physics of former and later two time slots of PUCCH is provided
Source block (Physical Resource Block, PRB) is located at the both ends of available frequency spectrum resource, this 2 PRB are constituted
One RB pairs, and intermediate monolith frequency spectrum resource is used for transmission Physical Uplink Shared Channel (Physical Uplink Shared
Channel, PUSCH).
With being widely used for LTE system, frequency spectrum resource is more and more nervous, meets certain private network demands using small bandwidth and mentions
Upper schedule.Such as subway and rail hand over the terminal quantity of this private network requirement also fewer, a train is with regard to a RRC connection sometimes
The terminal (CPE) of state.Typical small bandwidth system includes 1.4M system, 3M system and 5M system, and wherein 3M system bandwidth has
15PRB, 1.4M system bandwidth only have 6PRB, and small bandwidth PUCCH resource configuration is as shown in table 1:
The small bandwidth PUCCH resource allocation list of table 1
As can be seen from Table 1, PRB resource is more in short supply in small bandwidth system, even if according to PUCCH resource number minimal configuration
From the point of view of 2 PRB, for 1.4M bandwidth, 1/3 bandwidth is just occupied by PUCCH, and the bandwidth of residue 2/3 could give PUSCH
It uses, table 2 is upstream rate table corresponding with PUCCH resource, and as can be seen from Table 2, in 1.4M system, uplink PUSCH is adjustable
The maximum PRB number of degree is 4, and upstream rate maximum value is 895.2K, limits uplink throughput.
2 upstream rate of table table corresponding with PUCCH resource
Adjustable PUCCH mode carries out static or semi-static tune both for big bandwidth and multi-user's quantity scene at present
Whole PUCCH uses resource, and the period adjusted is long, furthermore the access of the user of public network and release all have it is certain with
Machine, periodically adjustment need the parameters such as repeater system information, cause the accuracy of model and implementation complexity high, are not suitable for small
The scene of bandwidth and individual user's quantity.In this way under the few scene of number of users scale, the rate of individual user is equal to entire cell
Mean Speed, if using the public network under large user's scale adjustment mode will sacrifice individual user's rate, to sacrifice cell
Overall rate.

In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
Fig. 1 is the distribution method flow diagram of ascending resource in small bandwidth system provided in an embodiment of the present invention, such as Fig. 1
It is shown, this method comprises:
Step S11, judge the shape of the first PRB resource of the corresponding Physical Uplink Control Channel PUCCH of current sub-frame of uplink
Whether state is idle state；
Specifically, since scheduling is realized in base station side, information relevant to ascending resource distribution is passed through by base station
Uplink authorization (UL grant) tell terminal device, and when terminal device first time access base station cell, base station can be according to excellent
The rule such as first grade is used for transmission the frequency spectrum resource of PUCCH information to terminal device distribution, is denoted as the first PRB resource, i.e. configuration should
Terminal device sends data in which PRB resource of which subframe.Therefore, it is set for accessing any one terminal of the base station
It is standby, which subframe which PRB resource send data be it is fixed, except non-terminal equipment discharges frequency spectrum resource, the terminal device
Corresponding first PRB resource is also just not present.Fig. 2 is that frequency spectrum resource provided in an embodiment of the present invention distributes schematic diagram, such as Fig. 2
Shown, base station is that each terminal device distributes a pair of first PRB resource, is used to indicate terminal device at two of the sub-frame of uplink
The corresponding PUCCH resource of time slot, and the two the first PRB resources are located at the both ends of available frequency spectrum resource, and centre connects
Continuous frequency spectrum resource is used for transmission Physical Uplink Shared Channel PUSCH information.
By shannon formula C=Blog2(1+S/N) it is found that in the case where system signal noise ratio and coding techniques are fixed, only
Channel capacity could be improved by being improved channel width B.Therefore, for each sub-frame of uplink, base station first determines whether current uplink
Whether the state of the first PRB resource of the corresponding Physical Uplink Control Channel PUCCH of subframe is idle state, i.e., in current uplink
Whether there is terminal device to need to send PUCCH information using the first PRB resource in subframe.In practical applications, base station stored
And the resource distribution table of terminal device is updated, which stores terminal device and sub-frame of uplink and the first PRB resource
Corresponding relationship, if some the first PRB resource is without corresponding terminal device in current sub-frame of uplink, i.e., in current sub-frame of uplink,
None terminal device uses the first PRB resource, then under current sub-frame of uplink, the state of the first PRB resource is sky
Not busy state, otherwise, the state of the first PRB resource are busy condition.
If the state of step S12, the described first PRB resource is idle state, the first PRB resource is added to institute
In the resource pool for stating the corresponding Physical Uplink Shared Channel PUSCH of current sub-frame of uplink；
Specifically, if base station judge the state of the first PRB resource for idle state, by the first PRB resource be added to
In the resource pool of the corresponding Physical Uplink Shared Channel PUSCH of current sub-frame of uplink, since the access terminal of small bandwidth system is set
It is standby less, therefore be easily met and used in the endless end equipment of some the first PRB resource of some sub-frame of uplink, i.e. the first PRB money
Source is idle, in this case, the first PRB resource allocation of PUCCH corresponding free time is used to PUSCH, increases PUSCH money
Source achievees the purpose that improve channel capacity, is a kind of method of dynamically sub-frame level expansion PUSCH resource.
Step S13, according to preset rules to described in the corresponding terminal device distribution of the Physical Uplink Shared Channel PUSCH
The first PRB resource in resource pool.
Specifically, in current sub-frame of uplink, if there is terminal device to need to send using Physical Uplink Shared Channel PUSCH
Information, then first PRB resource of the base station according to preset rules into terminal device distribution PUSCH resource pool, corresponding by PUCCH
Idling-resource distribute to PUSCH use, do not change used PUCCH resource, no changing system information and eat dishes without rice or wine to be reconfigured
The expense of message.
For example, system shares 6 PRB resources in the small bandwidth system of 1.4M, PUCCH resource is PRB0 and PRB5,
The resource of PUSCH includes PRB1 to PRB4, and in some sub-frame of uplink, the corresponding PRB resource of PUCCH is idle, then by PRB0 and
PRB5 is added in the resource of PUSCH, and the resource of PUSCH is made to be expanded to 6 resource blocks from 4 resource blocks before.Table 3 is upper
Scanning frequency rate table corresponding with PUSCH resource, it is as can be seen from Table 3, single to flow uplink most if PUSCH uses 2 PRB resources more
Big rate can be increased to 1349.22K (i.e. 1.3176M) from original 895.2k, improve nearly 50% rate.
3 upstream rate of table table corresponding with PUSCH resource
The distribution method of ascending resource in small bandwidth system provided in an embodiment of the present invention, will be idle under current subframe
PUCCH resource is added into the corresponding PUSCH resource pool of current subframe, for the scene of a small amount of user of small bandwidth, is not changed
Used PUCCH resource, the expense of no changing system information and reallocation message of eating dishes without rice or wine, dynamically expands making for PUSCH
With resource, so that upstream rate is improved, to improve the uplink throughput of small bandwidth system.
On the basis of the above embodiments, further, the corresponding physical uplink control of the current sub-frame of uplink of judgement
Whether the state of the first PRB resource of channel PUCCH is idle state, comprising:
Judge whether current sub-frame of uplink has control information to be sent；
If there is control information to be sent, judge whether the control information is PUSCH information；
If the control information is PUSCH information, it is determined that the corresponding physical uplink control letter of the current sub-frame of uplink
The state of the first PRB resource of road PUCCH is idle state.
Specifically, terminal needs to send necessary uplink L1/L2 control information UCI to support uplink and downlink data to transmit.LTE
System defines 2 kinds of different modes for sending uplink L1/L2 control information UCI: if terminal device does not have in current subframe
There is the ascending resource for being allocated for sending UL-SCH data, i.e. the corresponding PRB resource of PUSCH is denoted as the 2nd PRB resource, then
Terminal device sends uplink L1/L2 control information using PUCCH；If terminal device is assigned in current subframe for sending out
The 2nd PRB resource of UL-SCH data is sent, then terminal device sends uplink L1/L2 control information, i.e. L1/L2 using PUSCH
Control signaling and data-reusing PUSCH.The resource of PUCCH is at idle state at this time, and idle PRB resource all can be added
Into PUSCH resource pool for PUSCH use.If uplink service is continuous, PUSCH transmission L1/ is used without using PUCCH
L2 controls information, and the resource of PUCCH belongs to idle PRB resource, can be placed in PUSCH resource pool.Furthermore aperiodic
Property CSI can only be transmitted on PUSCH.In practical applications, terminal device sends SR request to base station first, to base station requests the
Two PRB resources, since the 2nd PRB resource is not distributed to terminal device under current subframe in base station, SR information is to pass through
What PUCCH was sent.After base station receives the SR request of terminal device transmission, second is distributed to the terminal device according to priority
PRB resource indicates that the 2nd PRB resource and correspondence of terminal device are distributed in base station by physical downlink control channel PDCCH
Sub-frame of uplink, after receiving PDCCH information, terminal device passes through line number in PUSCH transmission in corresponding 2nd PRB resource
According to no longer to base station transmission SR information.
Base station first determines whether current subframe has control information to be sent, if so, then judging that the control information is
PUSCH information or PUCCH information, since the same terminal device can only use one kind physically in the same sub-frame of uplink
Row channel (PUSCH or PUCCH) sends control information, therefore, if base station judges that determination is assigned with currently for terminal device
Subframe is corresponding for sending the 2nd PRB resource of UL-SCH data, then base station confirms control information to be sent for PUSCH letter
Breath, then the corresponding first PRB resource of PUCCH does not use under current subframe, and base station determines the corresponding physics of current sub-frame of uplink
The state of the first PRB resource of uplink control channel PUCCH is idle state.If base station confirms control information to be sent and is
PUCCH information, it is determined that currently the state of the first PRB resource of the corresponding Physical Uplink Control Channel PUCCH of sub-frame of uplink is
Busy condition.
The distribution method of ascending resource in small bandwidth system provided in an embodiment of the present invention, judges to be sent under current subframe
Control information be PUSCH information when, PUCCH resource idle under current subframe is added to corresponding to current subframe
In PUSCH resource pool, for the scene of a small amount of user of small bandwidth, used PUCCH resource is not changed, no system information changes
Become and the expense for reallocation message of eating dishes without rice or wine, dynamically expands the use resource of PUSCH, further improve upstream rate, thus
Improve the uplink throughput of small bandwidth system.
It is further, described to judge the corresponding physical uplink control of current sub-frame of uplink on the basis of the various embodiments described above
Whether the first PRB resource status of channel PUCCH processed is idle state, comprising:
Judge whether current sub-frame of uplink has control information to be sent；
If without control information to be sent, it is determined that the corresponding Physical Uplink Control Channel of the current sub-frame of uplink
The state of the first PRB resource of PUCCH is idle state.
Specifically, base station first determines whether current subframe has control information to be sent, since each terminal device exists
It is that base station is distributed to terminal device, therefore base station can be according to the allocated information which sub-frame of uplink, which sends control information,
Judge whether current subframe has control information to be sent, if there is no control information to be sent under current subframe, is working as
The corresponding first PRB resource of PUCCH does not use under preceding subframe, and base station determines the corresponding physical uplink control letter of current sub-frame of uplink
The state of the first PRB resource of road PUCCH is idle state, and the first PRB resource is added in the corresponding resource pool of PUSCH,
When terminal device needs to report acyclic CSI message, the first PRB resource transmission PUSCH information can be used.
Fig. 3 is to judge PUCCH resource in the distribution method of ascending resource in small bandwidth system provided in an embodiment of the present invention
Idle method flow schematic diagram, as shown in figure 3, this method comprises:
Step S31, base station judges whether current sub-frame of uplink terminal device has UCI to need to send, if so, thening follow the steps
S32, otherwise go to step S33；
Step S32, base station judges whether current sub-frame of uplink has PUSCH to need to send, if so, S35 is thened follow the steps,
It is no to then follow the steps S34；
