Embodiment
With reference to accompanying drawing, specify embodiment of the present invention below.
In the scheduling of HSUPA; Node B can insert (Uplink Packet Access to the upstream packet that scheduling is chosen; Abbreviation UPA) user is through strengthening absolute grant channel (Ehanced Dedicated Channel Absolute Grant Channel; Be called for short E-AGCH) send authorization message, wherein identified the information such as time slot, code channel and power mandate of giving this user, structure is as shown in Figure 1.Wherein, code channel mandate field, time slot mandate field and power mandate field all are 5 bit long.The E-HICH indication field is 2 bit long.Number indication (the E-UCCH Number Indicator of resource continuous indication (RDI) field, ascending control channel; Being called for short ENI) field, sequence number (E-AGCH Cyclic Sequence Number the is called for short ECSN) field that definitely strengthens authorization channel all be 3 bit long.ID/CRC (UE ID/CRC) is 16 bit long.Wherein, because RDI is optional, so the total length of E-AGCH channel information is 39 (no RDI) or 42bit (RDI is arranged).
In HSDPA; Node B inserts (DownlinkPacket Access can for the downlink grouped that receives data; Abbreviation DPA) user sends High-Speed Shared Control Channel (High SpeedShared Control Channel is called for short HS-SCCH) information, wherein comprises high speed descending sharing channel (High Speed Downlink Shared Channel; Abbreviation HS-DSCH) information such as data format in, structure is as shown in Figure 2.Wherein, the channelization code set identification field is 8 bit long.The time slot position information field is 5 bit long.Modulation intelligence is 2 bit long, can indicate three kinds of modulation system: QPSK, 16QAM and 64QAM.Transmission block size (Transport Block Size is called for short TBS) information field is 6 bit long.Mixed automatic repeat requests (Hybrid Automatic Repeat Request; Abbreviation HARQ) process identification (PID) field, redundancy versions (Redundancy Version; Abbreviation RV) information field and High-Speed Shared Control Channel cyclic sequence number (HS-SCCH CyclicSequence Number is called for short HCSN) field all is 3 bit long.The new data indication field is 1 bit long.Therefore the total length of HS-SCCH channel information is 47bit.
In the independent design of HSUPA and HSDPA, each E-AGCH and HS-SCCH are furnished with 2 spreading factors code channel of (Spectrum Factor is called for short SF)=16 respectively.Because HS-SCCH and E-AGCH are the signalings of Shi Caihui appearance that only is scheduled, so are acyclic.And be fixed as both respectively resources configured may cause a lot of wastes.
In order to reduce the expense of code channel, the present invention has designed a kind of method that can make E-AGCH and HS-SCCH time division multiplexing code channel resource.Each Transmission Time Interval (TransportTime Interval; Be called for short TTI) in; It still is HS-SCCH information that Node B is chosen in this physical resource transmission E-AGCH information as required; After UE receives and demodulates the information in the physical channel, own this Channel Transmission of judgement be E-AGCH or HS-SCCH.In order to make UE not have to judge channel type under the situation of other any additional information, the present invention has designed a kind of new AGCH frame format, and the corresponding judgment method, and main thought is following:
As shown in Figure 3, with the extended length of original E-AGCH channel, the channel logo field of interpolation can be used for distinguishing this two kinds of channels.In addition, also increased E-HICH indication (E-HICH Indicator is called for short EI) field in the E-AGCH channel architecture after the expansion.Just both can transmit E-AGCH information, also can be HSDPA user's transmisson of HS-SCCH information for HSUPA user with the time-slot code channel resource of a pair of SF=16.Be to adopt last 16 UE ID difference between the user.Receive UE and judge it is HS-SCCH channel or E-AGCH channel according to receiving data oneself.
Wherein, in the E-AGCH channel with HS-SCCH in the corresponding 5bit place of sign time slot position add complete 0 sequence.In addition, for unified length,, then in the E-AGCH channel, add complete 0 sequence of 3bit again if there is not RDI.
It should be noted that E-AGCH form and Fig. 3 after the expansion are not necessarily identical, as long as guarantee that the position of complete 0 sequence interpolation is the same with the bit position of sign time slot among the HS-SCCH.
Particularly, with reference to figure 4, the channel transmission method according to the embodiment of the invention is described.As shown in Figure 4, this channel transmission method may further comprise the steps: S402, radio network controller are that the absolute authorization channel that strengthens distributes identical channel resource with High-Speed Shared Control Channel; S404, the channel resource that Node B is passed through to be distributed definitely strengthens grant channel information or high speed shared control channel signal to user device transmissions; And S406, subscriber equipment is handled received information, and carries out downlink grouped access operation or upstream packet access operation according to result.
Wherein, step S404 may further comprise the steps: S4042, and Node B is selected definitely to strengthen grant channel information or high speed shared control channel signal to user device transmissions; S4044, Node B is according to selection result, will definitely strengthen grant channel information or high speed shared control channel signal is transferred to subscriber equipment.
Wherein, step S406 may further comprise the steps: S4062, and subscriber equipment judges according to the ID in the received information whether received information is the signaling information of oneself; S4064 is if then subscriber equipment judges that further received information is definitely to strengthen grant channel information or high speed shared control channel signal; And S4066, if received information is definitely to strengthen grant channel information, then subscriber equipment carries out the upstream packet access operation, otherwise subscriber equipment carries out the downlink grouped access operation.
That is to say that system's (radio network controller) is the HS-SCCH channel of HSDPA and identical time slot and the code channel resource of E-AGCH configuration of HSUPA.Node B is according to present needs information transmitted, and decision is HS-SCCH information or E-AGCH information in this channel.After UE received, first demodulation, decoding and CRC check judged whether it is the signaling information of oneself according to UE ID then.If this user signaling judges further that then this channel is HS-SCCH channel or E-AGCH channel.Determination methods is following: because the 5bit at time slot position place among the HS-SCCH can not be complete 0, be complete 0 sequence and E-AGCH adds herein.If therefore decode results shows that the 5bit here is complete 0 sequence, then be judged as the E-AGCH channel; If non-complete 0, then be judged as the HS-SCCH channel.According to judged result, UE can carry out corresponding D PA or UPA operation.Like this, through the same code channel resource of time-sharing multiplex, descending HS-SCCH and E-AGCH can reduce relevant code track resource distribution summation, reduce expense, increase the capacity of system.
The above is merely embodiments of the invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the claim scope of the present invention.
