Embodiment
Basic thought of the present invention is: only when the base station decision changes the shared physical resource of the HS-PDSCH of terminal monitoring, just send HS-SCCH to terminal; It is the physical resource of terminal distribution and the id information of terminal that the HS-SCCH that the base station sends only carries the base station, the HS-PDSCH carrying that other sends as information from base station such as TBS, NDI, that is to say that HS-PDSCH also carries information such as TBS, NDI except the bearing downlink business datum.
Below be described with reference to the accompanying drawings the realization that the present invention reduces method, base station, terminal and the system of HS-SCCH expense by specific embodiment.
Fig. 1 reduces the method flow schematic diagram of HS-SCCH expense for the present invention, and as shown in Figure 1, this method comprises:
Step 101: when Radio Resource control (RRC) link is set up, HS-SCCH and the HS-SICH of the feedback physical resource that take, physical resource that HS-PDSCH take and the basic transmission block size of network side high level by high-level signaling notice terminal monitoring; Simultaneously, physical resource information that takies for the HS-PDSCH of each terminal distribution by the signaling base station and basic information such as transmission block size.
Wherein, described high-level signaling can be the RRC signaling.
Step 102: the base station sends the HS-PDSCH data of counterpart terminal on the physical resource of the high-rise notice of network side, and described terminal receives HS-PDSCH and decoding on the physical resource of the high-rise notice of network side; Simultaneously, terminal promptly begins to continue to monitor the HS-SCCH that is notified in the signaling after receiving described high-level signaling.
Compared with prior art, HS-PDSCH is last except the bearing downlink business datum, also carries TBS and NDI message, can be placed on ad-hoc location behind these message codings, as transformat combination indication (TFCI) position.When terminal receives described HS-PDSCH, at first decode TBS and NDI, the information that obtains according to decode TBS and NDI is decoded to HS-PDSCH then, when HS-PDSCH decodes when correct, to base station feedback ACK, as it is incorrect to decode, and then saves the data in the buffer memory on HS-SICH.Wherein, specifically how to carry out the decoding of TBS, NDI and HS-PDSCH and how can use prior art, repeat no more here to base station feedback ACK.
In addition, how the base station sends HS-PDSCH and terminal and how to receive HS-PDSCH and all belong to known technology on corresponding physical resource, repeat no more here.
Step 103: when base station decision changes the shared physical resource of the HS-PDSCH of terminal monitoring, by sending HS-SCCH notice terminal.
After the base station sends HS-SCCH, start timing device and wait for that the ACK of terminal feeds back, if in the timing device setting-up time, receive described feedback, then on new physical resource, carry out the transmission of HS-PDSCH with terminal; After if timing device is overtime, the base station does not receive the ACK feedback of terminal, then resends HS-SCCH, till the ACK feedback that receives terminal.
Generally speaking, whether the base station changes the shared physical resource of HS-PDSCH of terminal monitoring according to self scheduling strategy decision, and how the base station specifically changes described physical resource according to self scheduling strategy decision and belong to known technology, repeats no more here.
Here, described HS-SCCH carrying base station is the new physical resource information and the Termination ID information of terminal distribution, and is identical in described physical resource information and the prior art, takies 13 bits, is used to indicate time slot and code channel information; The id information of terminal also takies 16 bits.The id information of described physical resource and terminal is carried on the code channel of a SF16 after encoding.Wherein, specifically how the id information of physical resource and terminal being encoded belongs to known technology, repeats no more here.
The time that described timer sets is depended on the factors such as disposal ability of terminal, for example can be set to: in maximum two TTI of the time interval (TTI)=n that send HS-SCCH, promptly at TTI=n+1 or the latest in TTI=n+2, do not receive that terminal feeds back about the feedback information of HS-SCCH the time, send HS-SCCH once more.
Step 104: when terminal receives described HS-SCCH, the HS-SCCH that receives is decoded.
Wherein, the HS-SCCH that specifically how to decode can use prior art, repeats no more here.
Whether step 105: terminal judges HS-SCCH decoding is correct, if correct, then execution in step 106; If incorrect, then execution in step 107.
Step 106: terminal on HS-SICH to base station feedback accordingly about the feedback information of HS-SCCH, afterwards, the physical resource that HS-PDSCH is taken is changed into the physical resource of HS-SCCH indication.
Wherein, the feedback information that terminal sends to the base station can for example use a kind of invalid TBS grade etc. with a kind of mode of feeding back ACK when being different from correct reception HS-PDSCH, can independently set according to practical application.
Step 107: the base station is sending HS-PDSCH on the physical resource of terminal distribution; Simultaneously, terminal receives HS-PDSCH and decoding on the physical resource that distributes for self, if decoding is correct, then on HS-SICH to base station feedback ACK; Incorrect if decode, then HS-PDSCH is kept in the buffer memory.
Wherein, when after the execution of step 106 during execution in step 107, be that to be correctly decoded the resulting base station of HS-SCCH in step 105 be the newly assigned physical resource of terminal to terminal for the physical resource of terminal distribution described in this step; When after the execution of step 105 during execution in step 107, the success because HS-SCCH does not decode, so described in this step for the physical resource of terminal distribution be original physical resource, at this moment, two kinds of situations of the same existence of described original physical resource, that is: before carrying out this step, when terminal was not correctly decoded the HS-SCCH that sends the base station, described original physical resource was: the network side high level is by the described physical resource of high-level signaling notice terminal; When terminal was correctly decoded the HS-SCCH that sends the base station, described original physical resource was: current terminal receives the employed physical resource of HS-PDSCH.
Wherein, how terminal specifically carries out the decoding of HS-PDSCH, identical with the method for describing in the step 102, repeats no more here.
In addition, in the method shown in Figure 1, the step when step 101 and step 102 have just been set up for the RRC link will be in case after terminal was correctly decoded the HS-SCCH that sends the base station, method shown in Figure 1 will be complete by step 103～step 107 sequential loop.
