Description
Technical field
The present invention relates to time division duplex (TDD, Time Division Duplex) technology, relate in particular to the control method and the device of a kind of high-speed shared information channel (HS-SICH).
Background technology
Development along with mobile communication technology; In order to improve traffic peak speed and power system capacity; In the existing 3G GSM, introduced high-speed packet access (HSPA) technology, HSPA comprises that high speed downlink packet inserts (HSDPA), high speed uplink packet inserts (HSUPA) and HSPA+.
In HSDPA, comprise 2 down channels: High-Speed Shared Control Channel (HS-SCCH) and high-speed physical downlink shared channel (HS-PDSCH) (HS-PDSCH); 1 up channel: HS-SICH.Wherein, HS-PDSCH is used for the bearing downlink business datum, does not carry any control information; HS-SCCH is used to carry the control information relevant with the HS-PDSCH business datum, and HS-SICH is used for carrying and feeds back read really symbol (ACK) and CQI (CQI) message.
In the HSDPA transmission of existing 1.28M tdd mode, network side is one group of HS-SCCH of each terminal configuration, and the terminal continues to monitor.Dispatch all users in the sub-district base station, after confirming as the terminal and sending the time and physical resource of data, notifies this terminal to prepare on corresponding physical resource, receiving data through HS-SCCH in advance.No matter first transmission perhaps retransmits, and concrete data transmission procedure is:
Step 101: high-rise corresponding relation between the HS-SICH of terminal indication HS-SCCH.
Wherein, the indicated relevant information of this step can be confirmed by high level, also can be confirmed by the base station, and is high-rise in the time of terminal indication relevant information when being confirmed by high level, and said relevant information is passed through the Iub interface informing base station; When being confirmed by the base station, high-rise through the Iub interface notice by the base station, afterwards, high level is redispatched to the terminal.High-rise when above-mentioned indication information is sent to the terminal, generally dose at high level and send in Radio Resource control (RRC) signaling at terminal.
Said high level is the node that radio network controller (RNC) etc. is in the upper strata, base station.
Wherein, the corresponding relation between HS-SCCH and the HS-SICH, network side is high-rise generally notified terminal and base station this corresponding relation before the transfer of data behind the base station access by terminal, between beginning terminal and the base station.Afterwards, scheduling and the control information of the HS-PDSCH that receive on which bar HS-SCCH at the terminal in the step 103 are just fed back on the HS-SICH of correspondence.
HS-SCCH is last to be carried to the uplink synchronous of HS-SICH channel and command word transmission power control command word (the TPC)/Synchronization Control (SS) of power control, and the power control messages of HS-SCCH is carried by HS-SICH.The structure of time slot of HS-SCCH and HS-SICH is shown in Fig. 1 a.
Step 102: the base station is sent data through HS-SCCH to the terminal.
On said HS-SCCH, carry scheduling and the control information of HS-PDSCH, be used on the follow-up HS-PDSCH of terminal indication, having the downlink data at terminal.
Step 103: the HS-PDSCH physical resource of said data indication is monitored in the terminal after receiving data on the HS-SCCH.
Step 104: data are sent through HS-PDSCH in the base station on said physical resource.
Step 105: after the terminal received data and decodes, to the corresponding information of base station feedback, current handling process finished on the HS-SICH corresponding with HS-SCCH.
Wherein, decode when correct, on HS-SICH, carry out the ACK feedback, otherwise, carry out the NACK feedback.
Use above-mentioned data transmission method, when utilizing HSDPA to carry voice (VOIP) business, the control signaling consumption of HS-SCCH is excessive, therefore, has proposed a kind of HS-SCCH-less operation.In this HS-SCCH-less operation, the initial transmission of data does not generally have HS-SCCH, but the high-rise HS-PDSCH physical resource of monitoring that be terminal distribution in advance, these physical resources are multiple users share, promptly a plurality of users monitor same physical resource.CRC (CRC) part at HS-PDSCH uses host ID (UE ID) to carry out mask, to distinguish the data of different user.The HS-PDSCH data are directly sent in the base station on these physical resources; HS-PDSCH data on the physical resource that the terminal continues RNC is distributed are carried out blind decoding, if decoding is correct, then carry out the ACK feedback at HS-SICH; Otherwise save the data in the buffer memory, do not carry out any feedback.Data transmission method under the above-mentioned HS-SCCH-less operation can combine with data transmission method shown in Figure 1; In step 102, confirm to use the HS-PDSCH physical resource of high-rise indication according to scheduling strategy or pass through HS-SCCH, and carry out the corresponding subsequent operation according to definite result once more to the new HS-PDSCH physical resource of terminal indication by the base station.
For the data transmission method after combining; The initial transmission under the situation of indication HS-PDSCH physical resource on the HS-SCCH is earlier confirmed in all re-transmissions and base station; Can adopt with existing HSDPA technology in similar HS-SICH control method, promptly the relevant control information of HS-SCCH indication is at first sent in the base station, comprises physical resource that HS-PDSCH takies etc.; The terminal has correctly received HS-SCCH; Just on corresponding physical resource, receive the HS-PDSCH data, decode, and on HS-SICH, carry out ACK or NACK feedback.
But when adopting the HS-SCCH-less operation to carry out transfer of data, HS-SCCH and HS-SICH transmit no longer at every turn all has relation one to one; For example, when data were transmitted first, the base station possibly indicated the HS-PDSCH physical resource through HS-SCCH to the terminal no longer earlier; But directly on HS-PDSCH, send data, at this moment, the terminal can't judge on which bar HS-SICH, to feed back through the HS-SCCH of correct reception data; And; Because the transmission frequency of HS-SCCH is lower than HS-SICH, the TPC of HS-SICH and SS message can not be carried on the HS-SCCH again, otherwise can influence power control and the Synchronization Control effect of HS-SICH.
