For making the object of the embodiment of the present invention, technical scheme and advantage clearly, 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, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
For ease of the understanding to the embodiment of the present invention, be further explained explanation below in conjunction with accompanying drawing for several specific embodiment, and each embodiment does not form the restriction to the embodiment of the present invention.
Embodiment one
HS-SFN (High-Speed Single Frequency Network, high speed single-frequency point network) is a design in multicast communication HSDPA technology.In HS-SFN, specify the multiple communities belonging to a NodeB as the community participating in HS-SFN, the community of this participation HS-SFN comprises a main Serving cell and at least one auxiliary serving cell.The data channel of the community of above-mentioned participation HS-SFN adopts identical scrambler, i.e. the scrambler of main Serving cell, and pilot tone and control channel then adopt the scrambler of respective community.NodeB utilizes the community of above-mentioned participation HS-SFN to the identical data of same UE synchronized transmission, and UE merges the data of the community of the participation HS-SFN received, to improve the performance of HSDPA user at cell edge.
In HS-SFN, UE measures the down channel situation of the community participating in HS-SFN, generates HS-SFN CQI (Channel Quality Indicator, channel quality indicates) information according to measurement result.HS-SFN CQI is carried on HS-DPCCH (Uplink High-Speed Dedicated Physical Control Channel, up link High-Speed Dedicated Physical Control Channel) channel and sends to NodeB by UE.
The HS-SFN CQI that NodeB sends according to UE, carries out data dispatch to the community of above-mentioned participation HS-SFN.Such as, if HS-SFN CQI is higher, illustrate that the down channel quality of the community of above-mentioned participation HS-SFN is good, NodeB dispatches larger data block and sends to UE by the community of above-mentioned participation HS-SFN.
When certain auxiliary serving cell in the community of above-mentioned participation HS-SFN does not have enough resources to leave HS-SFN for, this certain auxiliary serving cell can not participate in HS-SFN, NodeB sends to the data of UE to be lost by this certain auxiliary serving cell, and then causes NodeB to adopt HS-SFN mode to send data failure to UE.
The community that a kind of application scenarios schematic diagram transmitting the method for data to UE that this embodiment provides participates in HS-SFN as shown in Figure 1 comprises: a main Serving cell CELL1 and auxiliary serving cell CELL 2 of UE.In actual applications, the number participating in the auxiliary serving cell of HS-SFN can be multiple.Based on the application scenarios shown in above-mentioned Fig. 1, the handling process of a kind of method to UE transmission data that this embodiment provides as shown in Figure 2, comprises following treatment step:
Step 21, base station obtain the resource information of the community participating in HS-SFN, and described community comprises a main Serving cell and at least one auxiliary serving cell of UE.
Because above-mentioned main Serving cell and at least one auxiliary serving cell are all be under the jurisdiction of a base station, the resource informations such as the code channel of each community above-mentioned and power by base station assigns, so base station directly can obtain the resource situation of described each community.
In a wcdma system, above-mentioned base station is NodeB.
Step 22, described base station receive CQI and the HS-SFN CQI of the main Serving cell that described U E reports.
UE is according to the measuring intervals of TIME (such as 1MS) of setting, measure the channel quality obtaining main Serving cell and each auxiliary serving cell, this channel quality can be SNR (Signal to Noise, signal to noise ratio) or SIR (Signal to Interference, signal interference ratio) or SINR (Signal to Interference plus Noise, Signal to Interference plus Noise Ratio).
UE inquires about according to SNR or SIR of main Serving cell or SINR the CQI value that the mapping table preset obtains main Serving cell.
SNR or SIR of main Serving cell and each auxiliary serving cell or SINR measured value are combined according to certain merging criterion (as maximum-ratio combing, minimum mean-square error combining, geometric ratio merge etc.) by UE, finally obtain HS-SFN CQI according to the value query mappings table after merging.
The conversion relation of the conversion relation of SNR and CQI or the conversion relation of SIR and CQI or SINR and CQI is have recorded in above-mentioned mapping table.
The CQI feedback cycle that UE configures according to network side, by periodic feedback CQI on a HS-DPCCH channel, and two class CQI are fed back to NodeB in the CQI of feedback, i.e. CQI and the HS-SFN CQI of main Serving cell, under a kind of HS-SFN pattern that this embodiment provides, the structural representation of HS-DPCCH channel frame as shown in Figure 3, UE sends ACK/NACK at the 1st time slot of each 2ms subframe of HS-DPCCH, 2nd, 3 time slots send the CQI information of Serving cell, then, UE sends ACK/NACK at the 1st time slot of subsequent subframe, 2nd, 3 time slots send HS-SFN CQI information.
In actual applications, in order to ensure that UE is inerrably sent to NodeB by complete for CQI information, same CQI repeats to send repeatedly by UE usually.If repetition factor is N_cqi_transmit, the number that reports of the CQI of main Serving cell is N_cqi_prim, the number that reports of HS-SFN CQI is N_cqi_SFN, total CQI reports number N_cqi=N_cqi_prim+N_cqi_SFN, the CQI feedback cycle is k, k >=2ms*N_cqi_transmit.
CQI, according to above-mentioned CQI feedback cycle k, is sent to NodeB by HS-DPCCH subframe by UE.UE can select the CQI sending main Serving cell in a HS-DPCCH subframe; Or send HS-SFN CQI; Or other information sent except CQI and the HS-SFN CQI of main Serving cell.
Further, UE determines according to two Rule of judgment below the information needing transmission in a HS-DPCCH subframe:
Decision condition 1:
k '=k/ (2ms)
In above-mentioned formula
representative asks whole, mod represents complementation, CFN represents DPCCH (Dedicated Physical Control Channel, Dedicated Physical Control Channel) Connection Frame Number, 5 subframes are had in each frame (10ms), 7680 chips (chip) are had in each subframe (2ms), 5 × CFN converts frame number to subframe numbers, the time migration m (in units of 256chip) of 5 subframes corresponding to described CFN is calculated respectively by described decision condition 1, m × 256chip/7680chip asks whole process to be deviant deviant changed in units of subframe again.Because ask whole in decision condition 1, so 1 CFN can obtain 5 m.
