Description
Technical field
The present invention relates to the communications field, particularly relate to the method and the terminal of the terminal to report schedule information under the 3-G (Generation Three mobile communication system) TD-HSUPA technology.
Background technology
The TD-HSUPA business is divided into dispatching services and non-scheduling service by the difference of scheduling mode, wherein the resource of non-scheduling service is a terminal distribution by service wireless network controller (SRNC), when setting up, Radio Link just determines that network can only could change the non-scheduling service resource allocation conditions by wireless link reconfigured.Non-scheduling resource is mainly used in the signaling between transmission network and the terminal, the real-times such as business of constant rate require to compare higher data.Then (High-Speed Uplink Packet Access, HSUPA) resource are the terminal distribution ascending resource in real-time data transmission procedure by Node B to dispatching services again for Node B distributes the High Speed Uplink Packet access by SRNC.
No matter be dispatching services or non-scheduling service, in order to realize that network uses the reasonable distribution of Radio Resource, network all needs to understand in real time the transfer of data situation of terminal, so terminal need be to Node B reporting scheduling information (Scheduling Information, SI) obtain the scheduling of Node B, SI comprises the path loss metrical information of terminal buffers quantity, power headroom, this sub-district and adjacent sub-district etc.Concrete, Fig. 1 shows the composition structure of existing SI.As Fig. 1, SI comprises: this sub-district of 5 bits and the path loss difference of adjacent sub-district (Serving and Neighbor cell Path Loss, SNPL) information, the uplink transmission power surplus of the terminal of 5 bits (UE Power Headroom, UPH) information, buffer area data total amount (the TotalE-DCH Buffer Status of 5 bits, TEBS) information, the highest priority logical channel buffer area data volume of 4 bits (Highest Priority Logical Channel Buffer Status, HLBS) the highest priority logical channel identify label of information and 4 bits (Highest Priority Logical Channel Identity, HLID) information.
Terminal to report SI mainly contains following two kinds of situations:
The first, terminal does not have the HSUPA resource, but needs to send upstream data, then can initiate enhanced uplink random access channel E-RUCCH access procedure, is used to ask network to give the private resource of terminal distribution uplink; In 3GPP TS 25.321, this type of SI is called " authorization requests " type schedule information;
Second, terminal is being carried out under the situation of HSUPA transmission, no matter carry out dispatching services or non-scheduling service, and can be at packet MAC-e protocol Data Unit (Protocol Data Unit, PDU) carry SI information in, convenient network based SI information is adjusted authorization message at any time; In 3GPP TS 25.321, this type of SI is called " dispatch request " type schedule information.Above-mentioned MAC-e PDU refers to the data cell that the media access control layer that strengthens dedicated channel passes to physical layer.
The present invention is mainly concerned with second kind of situation of terminal to report SI, be that terminal has been set up link with network, carrying out to report the SI information of " dispatch request " type to network under the situation of HSUPA transmission, adjusting authorization message at any time with convenient network based SI information.In this case, terminal mainly reports the SI information of " dispatch request " type again by following 4 kinds of modes:
1. according to the triggering SI report condition of 3GPP TS 25.321 agreements regulation, have the data of higher priority logic channel to arrive such as terminal, perhaps strengthen dedicated channel E-DCH Serving cell and change, this must carry SI in MAC-e PDU;
2. network can be given terminal configuration periodically timer T-SI or T-SI-NST, behind timer expiry, can carry SI in the packet MAC-e PDU that terminal sends, do like this be for fear of terminal for a long time not SI reporting cause scheduling to stop; Wherein, when the network non-scheduled transmission of only having given terminal configuration, regularly sends SI request network adjustment authorization message, regularly send SI by timer T-SI under other situations and ask network adjustment authorization message by the T-SI-NST timer;
3. if terminal greater than schedule information SI length (23 bit), for fear of wasting space, also can be carried SI according to the remaining space of packet MAC-e PDU after holding the carrying logical channel data of current authorization message generation in packet MAC-e PDU;
4. this frame has authorization message but does not have the data cached transmission of logic channel, and for fear of the authorization message of this frame of waste, terminal also needs to generate the MAC-e PDU that only contains SI.
The present inventor finds in realizing process of the present invention, the starting point of reporting scheduling information is just for fear of the authorization message of wasting present frame in above-mentioned the 4th kind of situation, but in fact this to report not be essential: on the one hand, terminal is by timer T-SI or T-SI-NST, can guarantee periodicity to network reporting scheduling information SI, above-mentioned timer generally is to be made into default value 40ms; On the other hand, under the situation of carrying out the HSUPA transfer of data, terminal generally all can have enough spaces to contain the schedule information of 23 bits according to the MAC-e PDU that authorization message generates behind the carrying logical channel data.So, upload this MAC-e PDU that contains SI even reduce, network side also can in time be known the terminal latest development.The more important thing is that if this MAC-e PDU bust this that contains SI, the re-transmission that causes thus but is essential, can bring unnecessary burden to terminal.

Step 302 has judged whether that enhancing dedicated channel E-DCH Serving cell changes and the transmit buffer data volume becomes greater than 0 from 0; In this way, then establishment only contains the MAC-e PDU of SI, and sends to network side; Otherwise forward step 303 to;
Step 303, terminal be according to the transport-type of current network configuration, and whether being used to of judging that the medium access control (MAC) of terminal layer managed triggered the timer of reporting scheduling information overtime; Particularly, if there is the scheduled transmission type in network to the transport-type of terminal under current link, then whether terminal judges timer T-SI is overtime, and if T-SI is overtime, then sends the new MAC-e PDU that only contains schedule information, otherwise, execution in step 202; If network has only been joined non-scheduled transmission type to the transport-type of terminal under current link, whether terminal judges timer T-SI-NST is overtime, and if T-SI-NST is overtime, then sends the new MAC-e PDU that only contains schedule information, otherwise, execution in step 202.
Preferably, in the method for the embodiment of the invention, authorization message comprises: it is the physical resource that network side is distributed to terminal that network side issues.Exemplarily, this physical resource comprises: power resource, time interval resource and/or code channel.Terminal has authorization message at present frame and is terminal has the network side distribution at present frame physical resource.In the method for the embodiment of the invention, also comprised before steps A: terminal is determined definite step that logic channel that present frame has authorization message and a current configuration does not have data cached needs to send.Particularly, this determining step comprises:
Step 401, whether the terminal judges present frame has authorization message, and this authorization message can be scheduling authorization information or non-scheduling authorization information; As do not have authorization message, then the regulation by current agreement determines whether and need insert; Exemplarily, above-mentioned current agreement comprises 3GPP TS 25.321 agreements; If any authorization message, then change step 402 over to;
Whether step 402, the logic channel of the current configuration of terminal judges have data cached the needs to send, if exist data cached the needs to send, then set up MAC-ePDU according to current agreement such as 3GPP TS 25.321 agreements and send; Otherwise terminal changes execution in step 201 over to.
Exemplarily, in the method for the embodiment of the invention, step 202 comprises:
Step 501, terminal are determined the path loss difference (SNPL) of this sub-district and adjacent sub-district, uplink transmission power surplus (UPH), buffer area data total amount (TEBS), highest priority logical channel buffer area data volume (HLBS) and the highest priority logical channel identify label (HLID) of terminal;
Wherein, terminal pins is carried out the SNPL measurement to the HSUPA carrier wave, measurement result is defined as the SNPL of this carrier wave;
The power that terminal is measured and calculated the up-link carrier that uses, the difference between maximum transmission power that computing terminal is total and the already used up-link carrier power, and with this difference as UPH; Exemplarily, can utilize the method measurement of current agreement regulation and the power of the up-link carrier that calculating is used.
Terminal is defined as TEBS with all buffer data sizes of rlc layer and MAC layer;
Terminal is all at self, exist and select the highest logic channel of priority in the data logic channel to be passed, and its identity sign is defined as HLID, measures the data volume of this logic channel and measurement result is defined as HLBS.
Step 502, above-mentioned each element in the schedule information that terminal is calculated present frame and last time be go up the time and the schedule information of the immediate once transmission of present frame in each corresponding element compare one by one, each element homogeneous phase in the schedule information that is compared simultaneously, the schedule information of determining present frame is identical with the last schedule information that promptly sends recently, and process ends, regeneration does not only comprise the MAC-e PDU of SI; Otherwise, change execution in step 103 over to, generate the MAC-e PDU that only comprises SI, and be sent to network side by physical layer at present frame, finished control to the terminal to report schedule information.
The present inventor also finds in realizing process of the present invention, by when the MAC-ePDU bust this that only contains SI,, can avoid unnecessary retransmission to the control of the re-transmission of the MAC-e PDU that only contains SI, thereby, further improve the efficient of terminal to report schedule information.And, from the angle that retransmits, if only contain the MAC-e PDU bust this of SI, regulation by current agreement, need terminal to retransmit, but at this time the schedule information of Chong Chuaning might be out-of-date schedule information, wastes resource again and catches also and have little significance, so also be necessary from the angle that retransmits the transmission of the MAC-e PDU that only contains SI to be controlled.

Step 603 retransmits the MAC-e PDU that this comprises SI, and process ends;
Step 604 is removed the MAC-e PDU that this comprises SI, and process ends;
Step 605 retransmits the MAC-e PDU that this wait retransmits according to the regulation of current agreement.
The method of the embodiment of the invention, when waiting for the MAC-e PDU that only comprises SI that retransmits and the last time, the promptly the last MAC-e PDU that only comprises SI that sends was inequality, remove the MAC-e PDU that only comprises SI that this wait retransmits, no longer retransmit, thereby avoided re-transmission, saved terminal resource out-of-date schedule information.
According to the method for the embodiment of the invention, send failure if only comprise the MAC-e protocol Data Unit of SI, also comprise: judge whether the schedule information that comprises in the MAC-e protocol Data Unit of described transmission failure is identical with the last schedule information that sends; In this way, then retransmit described MAC-e protocol Data Unit; Otherwise, process ends.
Particularly, the method for the embodiment of the invention can be come waiting for that the MAC-e protocol Data Unit that retransmits retransmits according to following steps:
Step 701, terminal receives that network is to certain mixed automatic retransmission request (Hybrid AutomaticRepeat Request, HARQ) the affirmation information of process answer, exemplarily, terminal confirms to receive on the indicating channel (E-HICH channel) the affirmation information that above-mentioned HARQ process is replied at E-DCH HARQ;
Step 702 if the response message that carries in the above-mentioned confirmation is that ACK information is to confirm correctly to receive the MAC-e PDU that this HARQ process is carried, then empties this MAC-e PDU buffer memory, and empties corresponding HARQ progress information, otherwise change step 703 over to;
Step 703, this waits among the MAC-e PDU that retransmits whether only containing schedule information SI terminal judges; In this way, execution in step 704 then; Otherwise execution in step 605 is by the re-transmission of current agreement realization to this MAC-e PDU;
In this step, exemplarily, can whether be that 23 bits determine whether the MAC-e PDU that this wait retransmits only contains schedule information SI by the size of judging this MAC-e PDU transmission block; As be 23 bits, then illustrate among the MAC-e PDU that this wait retransmits and have only schedule information;
Step 704, whether the SI information that comprises among the MAC-e PDU that this wait of terminal judges retransmits is identical with the last SI information of promptly transmitting recently; In this way, retransmit this MAC-e PDU; Otherwise, empty this MAC-e PDU and corresponding HARQ progress information thereof.
In this step 704, can judge as follows exemplarily whether the SI information that comprises among the MAC-ePDU of this wait re-transmission is identical with the last SI information of promptly transmitting recently:
