Embodiment
Below in conjunction with drawings and Examples technical scheme of the present invention is described in detail.
When base station node B prepares to issue indication information by high-speed shared control channel HS-SCCH to terminal in advance when HS-PDSCH (High-Speed Physical Downlink Shared Channel) adopts single current mode or double-current mode to send.
Control channel transmits schematic diagram as shown in Figure 5, and end side is judged the data transfer mode of base station down HS-PDSCH (High-Speed Physical Downlink Shared Channel) channel according to the indication information of HS-SCCH (High-Speed Shared Control Channel) channel that receives; End side receives the HS-PDSCH data according to indication, and carries out the information feedback by the HS-SICH channel to base station side.
Basic conception of the present invention is: former HS-SCCH channel is expanded, and in this article, under non-MIMO pattern, former HS-SCCH channel architecture is called HS-SCCH TYPE1 (seeing Fig. 1).Under the MIMO pattern, the HS-SCCH channel architecture is called HS-SCCH TYPE2.It is 16 descending code channel that HS-SCCH channel after the expansion still keeps adopting two spreading factors, and still multiplexing SS (Synchronization Control) and TPC (transmitting power control) 4 bit synchronous power control information.
HS-SCCH TYPE2 is divided into two kinds of different types:
Channel code set identifier (CCS), time slot position information (TS), modulation system information (MF), transport block size information (TBS), the HARQ process identification (PID), redundancy versions indication information (RV) is with time slot user type indication information, HS-SCCH circulation serial number information (HCSN), wherein:
In the present embodiment, CCS takies 8 bits, and TS takies 5 bits, and MF takies 1 bit, and TBS takies 6 bits, and the HARQ process identification (PID) takies 3 bits, and RV takies 2 bits, takies 2 bits with time slot user type information, and HCSN takies 3 bits.
Wherein: be new field with time slot user type identification information field, be used for identifying and other users' of the identical time slot of active user type (such as MIMO user or non-MIMO user or without other users).Mainly be because under the MIMO pattern during single-stream transmission user can with the MIMO pattern under the stream transmission user assignment at identical time slot, also can be distributed in identical time slot with non-MIMO mode user, but because the MIMO type of user adopts different Mid-amble code (training sequence) methods of salary distribution from non-MIMO type of user, so terminal need know clearly that other user type of identical time slot is to guarantee that (terminal knows that user type just can know the method for salary distribution of Mid-amble code to the correct demodulation of terminal, thereby carry out correct demodulation thereby can obtain from the Mid-amble code that demodulation obtains the spreading code information that the user uses), identify with time slot user type identification field so need to be under the MIMO pattern increase during user's single-stream transmission.
Channel code set identifier (CCS), time slot position information (TS), the first modulation system information (MF1), the second modulation system information (MF2), the first transport block size information (TBS1), the first transport block size information (TBS2), the HARQ process identification (PID), the first redundancy versions indication information (RV1), the second redundancy versions indication information (RV2), HS-SCCH circulation serial number information (HCSN).
In the present embodiment, CCS takies 8 bits, and TS takies 5 bits, and MF1 takies 1 bit, and MF2 takies 1 bit, and TBS1 takies 6 bits, and TBS2 takies 6 bits, and the HARQ process identification (PID) takies 3 bits, and RV1 takies 2 bits, and RV2 takies 2 bits, and HCSN takies 3 bits.
Wherein:
Modulation system indication information (MF)
Keep original modulation system indication information field and also need increase the modulation system indication information that field is used for characterizing auxiliary transmission block outward.The modulation system of major-minor transmission block adopts independently mode to indicate respectively, in the single-stream transmission situation, and the fixing modulation system that adopts one of them field to represent single current, another field zero setting (it is invalid that can represent this moment zero).End side is obtained corresponding modulation system information by checking the correspondence position field information.For example arrange with terminal the base station: the modulation system of the corresponding expression of MF1 main flow, and the modulation system of the corresponding expression of MF2 secondary flow, terminal is determined respectively the modulation system of main flow and secondary flow by MF1 and MF2 so.
Transport block size information (TBS)
Keeping original transport block size information indication field also need increase the transport block size information indication that field is used for characterizing auxiliary transmission block outward, is divided into main transmission block TBS message identification field and auxiliary transmission block TBS message identification field.Using double-current HS-SCCH channel architecture to carry out in the situation of single-stream transmission, fixedly employing wherein a field represent the transport block size information of single current, the whole zero setting of another field are used for expression and adopt single-stream transmission.And can whether there be the zero setting state to distinguish the single double-current different transmission states of user according to the transmission block field.
The HARQ process identification (PID)
Keep original HARQ process identification (PID) field, major-minor transmission block adopts identical HARQ process number to identify.Adopt identical HARQ process number and can realize characterizing flexibly the different transmission situation of major-minor transmission block in conjunction with different separately RV version numbers.
Redundancy versions indication information (RV)
Keep original RV version indication information field and also need increase the RV version information that RV version indication information field is used for characterizing auxiliary transmission block outward.Major-minor transmission block adopts different separately RV version indication information fields.In the single-stream transmission situation, the fixing RV version indication information that adopts one of them field to represent single current, another field zero setting (it is invalid that can represent this moment zero).End side is obtained corresponding RV version information by checking the correspondence position field information.
Major-minor transmission block adopts identical channel code set identifier (the employed code resource allocation information of sign), time slot allocation information and HCSN information.
Certainly, TYPE2-A, TYPE2-B can also arrange otherwise, as long as base station side was appointed arrangement mode with end side before communicating by letter.Perhaps in other embodiments, can also represent whether be single-stream transmission with the MF2 that represents auxiliary transmission block and/or RV2, as can representing that with the combination of MF2 and RV2 when indicating with MF2 or RV2 separately, error rate may be relatively higher.
When transmitting simultaneously, can adopt major-minor transmission block identical HARQ process number and different RV version number to identify the difference transmission situation of major-minor transmission block, terminal is distinguished the current transmission state of different transmission blocks according to the different RV of major-minor transmission block version number, such as new data transmission or re-transmission.The specific implementation flow process is as follows:
● the equal feeding back ACK of major-minor transmission block then discharges this HARQ process;
● major-minor transmission block all feeds back NACK, then all needs to retransmit, and can be divided into two kinds of situations:
Current time is only suitable for transmitting single current, then at first selects main transmission block, and selects new RV version number to retransmit;
Current time is fit to the transmission double fluid, and then major-minor transmission block all selects new RV version number to retransmit simultaneously;
● feedback of major-minor transmission block is correct, and a feedback error then also can be divided into two kinds of situations:
Current time is only suitable for transmitting single current, then selects the transmission block of retransmission feedback mistake after the new RV version number;
Current time is fit to the transmission double fluid, then selects the transmission block of new RV version number retransmission feedback mistake can also transmit a new transmission block simultaneously again, and new transmission block adopts this HARQ process number and Initial R V version number to transmit.Terminal is distinguished re-transmission of blocks and new transmission block according to different RV version numbers.
Terminal for supporting the MIMO function in the network has two kinds of specific implementations:
When 1) end HS-PDSCH in base station carries out the single-stream mode emission, adopt HS-SCCH TYPE2-A emission, base station HS-PDSCH adopts HS-SCCH TYPE2-B emission when carrying out the double fluid emission;
2) end HS-PDSCH in base station carries out the emission of single double-stream mode and all adopts HS-SCCH TYPE2-B emission, adopt the frame structure concrete configuration of TYPE2-B emission single-stream mode as shown in Figure 4, utilize the bit of RV2 field to characterize with time slot user type flag information this moment, perhaps in other embodiments, the TBS with auxiliary transmission block carries with time slot user type flag information.
Because the total bit number of TYPE2-A and consistent 46 bits that are of former HS-SCCH channel bit number are so can adopt original mode that TYPE2-A is resolved.Because the total bit number of TYPE2-B has been increased to 53 bits, so needing to adopt new demodulation mode resolves TYPE2-B, so employing scheme 1 terminal need to be carried out twice blind check to realize the detection of HS-SCCH channel information, employing scheme 2 then terminal does not need to carry out blind check.
Fig. 2 Fig. 3 Fig. 4 just lists the field information that comprises in each structure type, is not limited to this arrangement mode.
