Detailed description of the invention
Below by the sharing method of the frame point multiplexed resource of DPCH with HS-PDSCH, the method for present embodiment is illustrated:
Below some herein presented concepts are explained.
Need supporting that DPCH Yu HS-PDSCH frame divides the time slot of multiplexing to arrange frame and divides the multiplexing cycle before carrying out resource distribution, frame divides the multiplexing cycle in units of radio frames, one frame divides and comprises at least one radio frames in the multiplexing cycle, such as, a frame can be set divide the multiplexing cycle comprises N number of radio frames, wherein, N=Integer (1
2,4,8,16,32,64), frame divides cycle restriction participation frame to divide the user of multiplexing to send the time interval of data, such as, if frame divides the time slot 0 of the radio frames 0 in the multiplexing cycle and radio frames 1 distribute to business 1 every time, then business 1 takies the time slot 0 of radio frames 0 and radio frames 1 in each frame divides the multiplexing cycle, and can not take frame again and divide the time slot in the radio frames 2 ~ radio frames N in the multiplexing cycle.
Also need to as using the signaling sharing resource or traffic assignments frame to divide multiplexing length, frame divides the number of the radio frames that multiplexing length takies within a frame divides the multiplexing cycle continuously equal to this signaling or business, frame divides the value of multiplexing length to divide the value in multiplexing cycle less than described frame, further, the duration that the frame of signaling or business divides multiplexing length corresponding is equal to the integral multiple of the Transmission Time Interval (TTI) of this signaling or business.
Fig. 1 is the method for the shared code channel resource of present embodiment, including:
Step 101: radio network controller (Radio Network Controller, RNC) is made whether to support the setting of resource-sharing to time slot；
RNC is made whether to support the configuration of HS-PDSCH Yu DPCH resource-sharing to descending time slot, and ascending time slot is made whether to support the configuration of E-PUCH Yu DPCH resource-sharing.
Step 102:RNC arranges frame and divides the multiplexing cycle radio frames, and frame divides and comprises at least one radio frames in the multiplexing cycle；
Step 103:RNC, when for DPCH Resources allocation, searches the exclusive code channel resource that whether there is DPCH in carrier wave, if it is present first exclusive for distribution DPCH code channel resource；Equally, base station (NodeB), when for HS-PDSCH or E-PUCH Resources allocation, the most first checks the exclusive code channel resource that whether there is HS-PDSCH or E-PUCH in carrier wave, if it is present first distribute exclusive code channel resource；
When the code channel resource deficiency that DPCH, HS-PDSCH or E-PUCH are exclusive, use shared resource.
Step 104: during distribution physical channel resources, if desired uses and shares resource, it is determined that need the physical channel resources number for signaling or traffic assignments；
When RNC is DPCH Resources allocation, it is first determined the frame that signaling or business use within a frame divides the multiplexing cycle divides multiplexing length, then determine the spread spectrum code taken and code channel number corresponding to every kind of spread spectrum code.
When NodeB is E-PUCH or HS-PDSCH Resources allocation, it is thus necessary to determine that signaling or business are at code channel number corresponding to subframe domestic demand spread spectrum code to be taken and every kind of spread spectrum code.
RNC determines when the frame that signaling or business use within a frame divides the multiplexing cycle divides multiplexing length and the spread spectrum code taken and every kind of spread spectrum code channel number corresponding to code, in order to make signaling or business still reach original request rate after using frame point multiplexed resource, need to revise signaling or the transformat of business.
First amendment signaling or the transformat of business, amended transformat needs to meet hardware circuit solution equal to signaling or K times of the former request rate of business, and wherein, K=frame divides the multiplexing cycle/and the frame of described amended transformat divides multiplexing length；
According still further to existing method, determine that the frame that signaling or business use within a frame divides the multiplexing cycle divides multiplexing length according to Transmission Time Interval in amended transformat；And determine spread spectrum code that signaling or business take and code channel number corresponding to every kind of spread spectrum code according to the size of transport block set in amended transformat.
Step 105: according to required physical channel resources number, searches idle physical channel resources and distributes to signaling or business.
When RNC is DPCH Resources allocation, searching assignable code channel according to the spread spectrum code that signaling or business take, assignable code channel needs to be in the code channel of idle condition in continuous N radio frames, and wherein, M divides multiplexing length more than or equal to the frame of described signaling or business；
When NodeB is E-PUCH or HS-PDSCH Resources allocation, searching assignable code channel in subframe, assignable code channel meets signaling or business and spread spectrum code requirement is in the code channel of idle condition.
When RNC is DPCH Resources allocation, idle physical channel resources is distributed to signaling or business includes: the time slot comprising assignable code channel is carried out prioritization, select time slot according to priority orders, the assignable code channel on selected time slot is distributed to signaling or business；And be signaling or the traffic assignments initial radio frames within frame divides the multiplexing cycle, it is hereby achieved that the numbering of initial radio frames；The frame that should be less than of the numbering of initial radio frames divides the value in multiplexing cycle, initial radio frames needs to meet condition 1, condition 1 includes: initiate the code channel for signaling or traffic assignments in N continuous the radio frames after radio frames within a frame divides the multiplexing cycle all in idle condition, wherein, N divides multiplexing length more than or equal to the frame of signaling or business.
When NodeB is E-PUCH or HS-PDSCH Resources allocation, idle physical channel resources is distributed to signaling or business includes: distribute to described signaling or business by code channel can be distributed described in described subframe.
During for DPCH Resources allocation, the above-mentioned time slot to comprising described assignable code channel carries out prioritization and initiates radio frames include for described signaling or traffic assignments: by all time slots comprising assignable code channel and all radio frames meeting condition 1, the code channel number taken by DPCH on every time slot of every radio frames is from being ranked up less, or by using the signaling number of DPCH and business number from more to few sequence on every time slot of every radio frames；According to the ranking results of every time slot of every radio frames, select the time slot of the radio frames that priority is the highest, using selected radio frames as signaling or the initial radio frames of business, the assignable code channel on selected time slot is distributed to use signaling or the business of DPCH.
During for E-PUCH or HS-PDSCH Resources allocation, distributed code channel in subframe is distributed to signaling or business includes: select not carry the time slot of the subframe of DPCH, the distributed code channel on time slot is distributed to use signaling or the business of E-PUCH or HS-PDSCH resource.
Time slot to the common signal channel place of community, it is also possible to as the time slot of resource-sharing.
Application example 1:
As in figure 2 it is shown, the uplink and downlink timeslot ratio of certain HSDPA carrier wave is as 2:4 in setting community, descending time slot TS3, TS4 and TS5 support that the frame of R4 business and HSDPA business divides multiplexing, and frame divides multiplexing cycle N=4.TS6 does not support that the frame of R4 business and HSDPA business divides multiplexing, and numbers 8 less code channel configurating downlink CCCHs, and numbering 8 bigger code channels is code channel exclusive for DPCH.
In the case of carrier wave zero load, successively access 1 the up 64Kbps/ of CS descending 64Kbps video traffic, 1 the up 16Kbps/ of PS descending 16Kbps data service, the HSDPA business of 1 descending 2Mbps of up 64Kbps/, below the situation of the distribution of down channel resources is illustrated:
When the video traffic of the descending 64Kbps of the up 64Kbps/ of step A:CS accesses, RNC searches code channel resource exclusive for DPCH on carrier wave, and calculate the physical channel resources number needed for video traffic, obtain that descending to need to distribute 8 spreading factors be the code channel of 16, therefore distribute to video traffic by numbering code channel exclusive for 8 bigger DPCH on TS6；
When the up 16Kbps/ of step B:PS descending 16Kbps data service accesses, the resource exclusive due to DPCH is the most occupied, therefore the shared resource of distribution R4 Yu HSDPA, determine the physical channel resources number needed for descending 16Kbps data service；
Owing to frame divides the multiplexing cycle to be 4, frame divides multiplexing a length of 2, i.e. within a frame divides the multiplexing cycle, 16K data service takies 2 radio frames, takies the resource distribution mode of radio frames continuously relative to data service in prior art, and the speed of 16K data service becomes the 1/2 of original speed.In order to meet the rate requirement of business, need to revise transformat, the speed of amended transformat need to meet frame and divide the multiplexing cycle the/speed × former request rate of amended transformat, the transformat of this business can be revised as the transformat of 32K, wherein, TTI is constant, and transport block size is constant, transmission block number becomes original 2 times, thus also ensures that original speed after frame divides multiplexing.
32K business is descending to be needed to take 4 spreading factors is the code channel of 16, thus this business to need to distribute 4 spreading factors in down channel be the code channel of 16, and take continuous 2 radio frames.
The code channel that all spreading factors are 16 on descending shared time slot TS3, TS4, TS5 is all to distribute code channel, and initial radio frames can select radio frames 0,1,2, and this service needed can be met and take the requirement of 2 radio frames continuously.
Meeting in the radio frames that initial radio frames require due to all, all comprise the time slot that can distribute code channel, the code channel number taken by every radio frames every time slot statistics DPCH, is all 0.Therefore arbitrarily select the distributed code channel on available time slot, and initial radio frames.Final allocation result is as shown in Figure 2.
Step C: during the HSDPA service access of the descending 2Mbps of up 64Kbps/, for the adjoint channel Resources allocation of HSDPA business；
If signaling is 3.4Kbps signaling, after frame divides multiplexing, the transformat of signaling being revised as the transformat of 13.6K with channel only carrier signaling due to descending, wherein, it is the most constant that TTI becomes 10ms, transport block size and transmission block number.13.6K signaling is descending to be needed to distribute 2 spreading factors is the code channel of 16, thus this signaling to need 2 spreading factors distributing certain time slot under 1 radio frames be the code channel of 16 descending.
The code channel that spreading factor is 16 available free on descending shared time slot TS3, TS4, TS5 is all to distribute code channel, and initial radio frames can select radio frames 0,1,2,3, and this service needed can be met and take the requirement of 1 radio frames continuously.
Meet in the radio frames that initial radio frames requires due to all, all comprise the time slot that can distribute code channel, by every radio frames every time slot statistics code channel number of having taken of DPCH from more to few sequence, the code channel number that the TS3 of the radio frames 0 and TS3 of radio frames 1 on, DPCH has taken is all 4 to be maximum.Therefore selecting the distributed code channel on TS3, initial radio frames selects radio frames 0 or 1.Final allocation result is as shown in Figure 2.
Step D: when the HSDPA traffic scheduling of descending 2Mbps, the descending time slot of the idle subframe not carrying DPCH in frame divides the multiplexing cycle is distributed on this business.
Application example 2:
As it is shown on figure 3, the uplink and downlink timeslot ratio of certain HSUPA carrier wave is as 3:3 in setting community, ascending time slot TS1, TS2 and TS3 support that the frame of R4 Yu HSUPA business divides multiplexing, and frame divides multiplexing cycle N=2.8 code channel fixed configurations that numbering corresponding for TS1 is less are uplink common control channel.
In the case of carrier wave zero load, successively access 1 the up 32Kbps/ of PS descending 32Kbps data service, the scheduling HSUPA business of a descending 32Kbps of up 2Mbps/, below the distribution condition of uplink channel resources illustrated:
When the up 32Kbps/ of step a:PS descending 32Kbps data service accesses, the DPCH resource exclusive owing to there is not R4 business, therefore, in distributing carrier wave, the frame of R4 Yu HSUPA business divides the resource of multiplexing, determines the physical channel resources number needed for business；
Assume that the Transmission Time Interval (TTI) of PS 32K data service is equal to 20ms, the duration dividing multiplexing length corresponding due to the frame of business needs the integral multiple equal to TTI, therefore frame can be set and divide duration corresponding to multiplexing length equal to 20ms, owing to frame divides the multiplexing cycle to be that 20ms is equal to frame and divides multiplexing length, therefore the transfer rate of business is constant after multiplexing, the transformat that can keep business is constant.It is the code channel of 4 that 32K data service up needs to take a spreading factor, thus this business to need to distribute a spreading factor in up channel be the code channel of 4, and divide at a frame cycle take continuous 2 radio frames distribution.
The code channel that spreading factor is 4 available free on up shared time slot TS1, TS2, TS3 is all to distribute code channel, and initial radio frames can select radio frames 0, can meet this service needed and take the requirement of 2 radio frames continuously.
Meet in the radio frames that initial radio frames require due to all, all comprise the time slot that can distribute code channel, by using signaling number and the business number of DPCH on every time slot of every radio frames, be all 0.Therefore arbitrarily select the distributed code channel on available time slot, and initial radio frames.Final allocation result is as shown in Figure 3.
Step b: during the scheduling HSUPA service access of the descending 32K of up 2M/, for dispatching the adjoint channel Resources allocation of HSUPA business；
If signaling is 6.8Kbps signaling, after frame divides multiplexing, the transformat of signaling can be revised as the transformat of 13.6K with channel only carrier signaling due to up, wherein, it is the most constant that TTI becomes 10ms, transport block size and transmission block number.
It is the code channel of 8 that 13.6K signaling up needs to distribute 1 spreading factor, therefore needs the spreading factor distributing in certain ascending time slot in 1 radio frames to be the code channel of 8 with the up direction of channel.
The code channel that spreading factor is 8 available free on up shared time slot TS1, TS2, TS3 is all to distribute code channel, and initial radio frames can select radio frames 0,1, and this service needed can be met and take the requirement of 1 radio frames continuously.
Meet in the radio frames that initial radio frames requires due to all, all comprise the time slot that can distribute code channel, sorting from more to few by the signaling number and business number using DPCH on every time slot of every radio frames, the business number that the TS1 of the radio frames 0 and TS1 of radio frames 1 uses DPCH is all 1, for maximum.Therefore selecting the distributed code channel on TS1, initial radio frames selects radio frames 0 or 1.Final allocation result is as shown in Figure 3.
Step c: when dispatching HSUPA traffic assignments resource, can be distributed on this user by the time slot of the idle subframe of the up DPCH of carrying.
