Description

The transmission method of HS-DSCH under the non-cell private channel status

Technical field

The present invention relates to the communications field, relate more specifically to the HS-DSCH transmission method under a kind of non-cell private channel status.

Background technology

High-speed packet inserts (High Speed Packet Access; Abbreviation HSPA) comprises 3G (Third Generation) Moblie partnership (3rd Generation Partnership Project; Abbreviation 3GPP) two big technology in the protocol architecture; Enhancing dedicated channel (Enhanced DedicatedChannel the is called for short E-DCH) technology that the high speed downlink packet of promptly in the Rel-5 version, formulating inserts (High Speed Downlink Packet Access is called for short HSDPA) technology and in the Rel-6 version, formulates; Be commonly referred to high speed uplink packet and insert (HighSpeed Uplink Packet Access is called for short HSUPA) technology.The introducing of HSPA technology makes the data service bearing capacity of the third generation (Third Generation is called for short 3G) network of 3GPP strengthen greatly, and the availability of frequency spectrum also is significantly improved.System is an example with TD SDMA (Time Division-Synchronous Code Division MultipleAccess, be called for short TD-SCDMA), and HSDPA can provide the downlink data throughput of the highest 2.8Mbps.

At down link; Utilize Transmission Time Interval (the Transmission TimeInterval of 5ms; Be called for short TTI), adaptive coding and modulating (Adaptive Modulation andCoding is called for short AMC), mix automatically retransmit (Hybrid Automatic RepeatRequest is called for short HARQ), based on the scheduling of Node B (base station), and key technology such as shared channel; HSDPA can the fast adaptation wireless environment variation, dynamically adjust the data throughput of down link; Through transferring Traffic Channel to " sharing " from " special use ", make more user share descending wireless bandwidth, thereby effectively improved wireless resource utility efficiency.

When initial design HSDPA technology; With application limitations at CELL _ DCH (CELL_DCH) state; Network side is being user terminal (the User Equipment that is in the CELL_DCH state; Be called for short UE) foundation high speed-DSCH Downlink Shared Channel (High SpeedDownlink Shared Channel; Be called for short HS-DSCH) during relevant radio bearer, dispose one group of high speed-shared control channel (High Speed Shared ControlChannel is called for short HS-SCCH) and high speed-shared indicating channel (High Speed SharedIndication Channel for UE in advance; Be called for short HS-SICH) and a high speed descending sharing channel-Radio Network Temporary Identifier (HS-DSCH Radio Network Temporary Identifier is called for short H-RNTI).This group HS-SCCH/HS-SICH channel is that a plurality of UE share, and H-RNTI is the UE special use, and UE judges through the H-RNTI on the identification HS-SCCH whether this transmission points to oneself.In case detected the HS-SCCH channel that points to oneself; Just read the information on the HS-SCCH channel; The last concrete signaling content of HS-SCCH is as shown in table 1; Wherein, code channel and gap information indication UE are about to the channel resource of the high speed down sharing physical channel (High Speed Physical Downlink Shared Channel is called for short HS-PDSCH) of reception; Modulation system and transport block length indication transformat.After time, UE receives data on the HS-PDSCH of appointment channel in predetermined timing, and on the HS-SICH channel, is mixing automatic repeat requests (Hybrid Automatic Repeat Request is called for short HARQ) feedback behind the timing of appointment.

Control information in table 1 prior art on the HS-SCCH

Code channel (8 bit)

Time slot (5 bit)

Modulation system (1 bit)

Transport block length (6 bit)

HARQ process number (3 bit)

Redundancy versions (3 bit)

New data indication (1 bit)

Sequence number (3 bit)

In the Rel-7 version, 3GPP has accomplished the standardization effort that sub-district _ forward access channel (CELL_FACH) state in WCDMA access (WidebandCode Division Multiple Access the is called for short WCDMA) system strengthens.The CELL_FACH state strengthens through introducing the packet data transmission performance that the HS-DSCH transmission channel strengthens this state at the CELL_FACH state, makes it obtain less packet transfer delay and higher transmission rate.This mechanism also has been incorporated into paging and the transfer of data under UTRAN Acceditation Area _ PCH (URA_PCH) and cell _ paging channel (CELL_PCH) state.

When carrying out the HS-DSCH transmission under the CELL_FACH state, information such as HS-SCCH channel, H-RNTI are broadcasted in cell system information.Because these H-RNTI are shared by the UE in the sub-district, thereby are called public H-RNTI.When UE initiates connection request from Idle state, use the public H-RNTI in the cell system message to intercept the HS-SCCH channel.A plurality of public H-RNTI are arranged in the sub-district, and UE selects the method for H-RNTI:

The index of selected H-RNTI=UE sign mod K.Wherein, K is the number of the H-RNTI in the public H-RNTI tabulation in the cell system broadcasting; For the UE of idle condition, the UE sign is the initial marking that UE carries in Radio Resource control (Radio Resource Control is called for short RRC) connection request message; For the UE of connection status, the UE sign is UTRAN Radio Network Temporary Identifier (URTAN Radio NetworkTemporary Identifier is called for short U-RNTI).A public H-RNTI will be shared by a plurality of UE.

HS-DSCH transmission course under the CELL_FACH state is as shown in Figure 1, and different with transmission course under the CELL_DCH state is that UE need not carry out the HARQ feedback.In case UE has detected HS-SCCH and has gone up one's own public H-RNTI; Just receive the HS-PDSCH data according to the indication on the HS-SCCH; And it is back through sign of the UE in the RRC message of upper strata or public medium access control (Medium Access Control that the HS-PDSCH data are correctly decoded; Abbreviation MAC) to one's name whether the U-RNTI in the protocol Data Unit (Protocol DataUnit is called for short PDU) come recognition data.

After UE gets into connection status; Radio network controller (Radio NetworkController; Be called for short RNC) be UE configure dedicated communication channel (Dedicated TrafficChannel; Be called for short DTCH)/DCCH is in the time of (Dedicated Control Channel is called for short DCCH), the H-RNTI of configure dedicated.UE uses special-purpose H-RNTI to receive the HS-SCCH channel after possessing special-purpose H-RNTI, does not receive and do not re-use public H-RNTI.

Because a series of enhancement techniques of HS-DSCH itself (as based on the scheduling of Node B, HARQ etc.) can improve data transfer rate effectively, thereby will significantly improve signaling delay and the data transfer rate under the CELL_FACH state behind the introducing HS-DSCH.TDS-CDMA system (Time Division Synchronous Code Division Multiple Access is called for short TD-SCDMA) also considers to carry out similar enhancing.

The UE that shares a public H-RNTI need receive all HS-DSCH relevant with this public H-RNTI transmission.As previously mentioned, one time the required signaling information of HS-DSCH transmission passes through the HS-SCCH Channel Transmission, and the signaling content is as shown in table 1, and code channel wherein, time interval resource all should satisfy the physical layer ability of UE.In addition, in the TD-SCDMA system, transport block length indicates corresponding transport block length value also because of the ability of UE different (the transport block length indication can save with reference to 3GPP agreement TS25.3219.2.3.3 with the corresponding of transport block length value).For example, when transport block length was designated as 10, HSDAP ability classification was that 3 UE can resolve to 342 bits with it; And being 6 UE, HSDAP ability classification can it be resolved to 379.By the system of selection of existing public H-RNTI, the ability classification of intercepting the UE of same public H-RNTI obviously is diversified, thereby according to existing standard, and Node B can't confirm the scheduling resource and send signaling how to public H-RNTI user.

TD-SCDMA system with 3G is that the example specific embodiments of the invention is elaborated below.

Instance one

RNC and Node B need set up the HS-DSCH resource that the CELL_FACH state uses down in the sub-district, comprise by RNC setting up transfer of data, the Node B resource pool that HS-DSCH is relevant from sub-district distribution HS-SCCH channel and the public H-RNTI that public MAC stream is used for the Iub mouth.HS-SCCH channel and public H-RNTI information are in " high-speed downlink shared transmission channel public system information " information unit of cell system message piece 5 or 5bit.

This instance only just possibly take place under the situation that following two conditions all satisfy:

1) network side is broadcasted " high-speed downlink shared transmission channel public system information " (UE judges sub-district support CELL_FACH enhanced characteristic in view of the above) in cell system message.

2) UE supports the HSDPA under the CELL_FACH state to receive.

With reference to figure 5, the process that on HSDPA, receives the down initial signaling according to the embodiment of the invention is described.As shown in Figure 5, this process specifically may further comprise the steps:

S502, UE initiates the RRC connection request, sets up reason, whether supports the ability information of HSDPA reception under the CELL_FACH state etc. with going up connection.Here suppose that UE is supported in reception HSDPA under the CELL_FACH state.UE also need select a public H-RNTI according to the public H-RNTI tabulation of broadcasting in the system broadcast message.Here adopt the system of selection described in the background technology to select a public H-RNTI.The HS-SCCH channel that UE broadcasts in the interception system message subsequently judges that whether wherein public H-RNTI is exactly the public H-RNTI of oneself selection.

S504; RNC admits control; Decision allow UE to insert and decision with the UE CELL_FACH state of moving into; RNC sends Frame through HS-DSCH Frame Protocol type 2 to Node B on public medium access control (Media Access Control the is called for short MAC) stream of Iub mouth definition, message data stream is set up in the information, the RRC connection that wherein comprise recipient's H-RNTI.Though having pointed out this among the figure is that message is set up in a RRC connection, for Node B the data (transmit the transparent reception of Node B back) that common HS-DSCH goes up transmission.

S506; It is after sharing the user terminal of public H-RNTI that Node B identifies the recipient; When being this H-RNTI scheduling resource; Minimum HSDPA physical layer ability according to system definition is confirmed transmission parameter, and in existing system, HSDPA physical layer ability comprises the maximum HS-PDSCH code channel number of every time slot, maximum HS-PDSCH timeslot number, a HS-DSCH transmission channel bit number and the maximum soft channel bit number that TTI is maximum of every TTI.Existing system has carried out quantizing and classification to these abilities, and the HSDPA physical layer ability classification of TD-SCDMA is as shown in table 2.Wherein, lowest capability is a classification 1.For the multi-carrier HSDPA system, except above ability classification, also comprise the carrier number that the terminal can receive simultaneously, like single carrier, 3 carrier waves, 6 carrier waves etc.Node B is according to above lowest capability parameter (being that physical layer ability classification 1, single carrier receive); Confirm on which carrier wave, to send; And definite HS-PDSCH resource size (sign indicating number resource and time interval resource), transport block length indication and modulation system; And these parameters are sent to UE through the corresponding HS-SCCH channel of this carrier wave, wherein also carry the information of H-RNTI;

S508; The H-RNTI that UE detects among the HS-SCCH is own selected public H-RNTI; Resolve Control Parameter wherein; Use minimum HSDPA physical layer ability classification to resolve transport block length field (corresponding relation of physical layer ability classification and transport block length is referring to MAC standard TS25.321), and the data on the HS-PDSCH that receives Node B transmission after system's predetermined timing time (wherein comprise the RRC connection and set up message).

S510, UE sends response message (being the RRC connection setup complete message) here to RNC.

Instance two

Application scenarios when also may be advanced into CELL_PCH and URA_PCH state down through HS-DSCH Channel Transmission beep-page message according to embodiments of the invention.At present, and use HS-SCCH-Less when having confirmed under these two states, to send beep-page message (, do not send HS-SCCH) and operation.Network side Page Indication Channel (the Paging Indicator Channel that RP Radio Paging is used in cell system information; Be called for short PICH) and corresponding HS-PDSCH channel set (configurable 16 pairs of PICH channels and HS-PDSCH channel at most) go up the transport block length of sending the beep-page message use with HS-PDSCH and gather (2 transport block length); UE and network side are selected a HS-PDSCH code channel according to set rule, when receiving HS-PDSCH, need carry out blind decoding to 2 transport block length.One time the beep-page message process of transmitting is as shown in Figure 6:

UE receives PICH (i.e. 602 among the figure) channel in DRX (discontinuous reception) receiving cycle after; If (Page Indicator is indicated in the paging that detects on the paging indicating positions that is complementary with own sign; Be called for short PI, i.e. PI1...PIn among the figure) be complete 0 (that is, invalid PI); The HS-PDSCH that then ignores the back gets into the DRX state again; If PI is complete 1 (that is, effective PI), receives HS-PDSCH channel (i.e. 604 among the figure) behind the Ngap that then will squint at a fixed time, and utilize given transport block length set to carry out blind decoding; After decoding successfully, send into rrc layer and resolve this beep-page message, judge through the sign of the UE in the message (Identification is called for short ID) whether this beep-page message is sent out to oneself.In order to ensure the reliability that receives, Node B will send identical data continuously on continuous N sub-frame, and UE receives the HS-PDSCH channel on the N sub-frame continuously and carries out soft merging.

Send beep-page message through the HS-DSCH channel and also have same problem; Because may being in a plurality of UE of CELL_PCH state and URA_PCH state in the sub-district, PICH and follow-up beep-page message receive simultaneously; Network side is when physical resource that customizes the beep-page message use and transformat (like transport block length); Can the UE that also need consider the lowest physical layer ability receive, the problem that how same existence resolves for transport block length.As, for transport block length, in order to save the RRC signaling consumption, the transport block length information that is used for the beep-page message reception of from system message, sending generally is the transport block length indicated value, and is as shown in table 3:

Transport block length information when table 3 HS-DSCH goes up the transmission beep-page message

Information unit	Essential	List information	Type	Note
					The transport block length tabulation	Essential	1..2	?	?
The indication of＞transport block length	Essential	?	Integer (0..63)	The transport block length indication is worth corresponding can saving with reference to TS25.321 agreement 9.2.3.3 with transport block length

Like this, the UE in the sub-district should come the parameter shown in the resolution table 3 according to the minimum HSDPA ability classification of system definition.Information shown in the table 3 equally also can dispose B to Node, and Node B also should come the parameter shown in the resolution table 3 according to the minimum HSDPA ability classification of system definition.

It should be noted that the TD-SCDMA system does not also accomplish the standardization effort that CELL_FACH strengthens at present.When TD-SCDMA formulates the standard of CELL_FACH enhancing; The UE that may limit some HSDPA classification can not use and strengthen the CELL_FACH enhanced characteristic; In this case, the minimum HSDPA physical layer ability classification of HSDPA refers to minimum available HSDPA physical layer ability classification under the non-CELL _ DCH state.

Relevant with setting up carrying at present RRC signaling can be able to simplify through using default configuration; Other RRC signaling data amounts are also little, thereby the minimum physical layer ability of using system definition is carried out the influence that the transmission of transmission and beep-page message under the public H-RNTI can not bring the efficiency of transmission aspect; And HSDPA supports continuous dynamic dispatching and transmission, can send through multiframe for big signaling data.In addition, the present invention need not revise interface protocol, simple possible.

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.
