Technical field
The present invention relates to the transmission in the Long Term Evolution of Universal Mobile Telecommunications System (UMTS) terrestrial radio access network (UTRAN) or UTRAN, more specifically, relate to the UTRAN high-speed downlink packet access (HSDPA) in CELL_FACH (forward access channel) state.
Background technology
As known in the art, one of Wideband Code Division Multiple Access (WCDMA) (WCDMA)/Universal Mobile Telecommunications System (UMTS) communication system further development is to have defined the system that is known as high-speed downlink packet access (HSDPA).HSDPA operates as shared communication channel of time, the possibility that it provides the potentiality of peak value data transfer rate and has spectral efficient.HSDPA has improved power system capacity and has improved user data rate in down link, so-called down link, the i.e. transfer of data from radio base station (RBS) to subscriber equipment (UE), wherein radio base station is also known as Node B server in UMTS system.
Fig. 1 shows the radio interface protocol structure of HSDPA.It shows the relation of different layers between UE, Node B and various radio network controller (RNC).In Fig. 1, RLC is RLC layer, and MAC is media access control layer, and PHY is physical layer.MAC-hs (MAC at a high speed) is the new MAC entity stopping in Node B, for controlling HS-DSCH transport layer.MAC-c (common MAC) is the entity in UE, and it uses the service of physical layer that MAC-c PDU (protocol Data Unit) is sent to the reciprocity MAC-c entity in RNC.MAC-c/sh is responsible for PCH (paging channel), FACH (forward access channel), DSCH (downlink sharied signal channel) and RACH (Random Access Channel).MAC-d (special MAC) is responsible for dedicated channel (DCH), and stations in Serving RNC, and MAC-c/sh is arranged in control RNC.L1, L2 are the transmission network layer protocols between Node B and Serving RNC.
HS-DSCH channel is the downlink transmission channel of being shared by multiple UE.The down link DPCH (downlink dedicated physical channels) of HS-DSCH and one of each any active ues or F-DPCH and one or more shared control channel (HS-SCCH) are associated.HS-DSCH for example can use beam forming antenna to transmit on whole community or in a part for Jin community.
Although HSDPA be within the relatively less period (Transmission Time Interval of HSDPA system in other words TTI is 2ms) send the effective ways of relative mass data, but, this performance only could be used in the time that subscriber equipment operates in dedicated channel status (CELL_DCH state), in other words, physical layer between UE and Node B is connected to be set up and after this layer of connection have the dedicated channel of distributing to it, could use.UE is to the transformation of dedicated channel status (CELL_DCH state) and set up HSDPA and connect the time that may consume one second.Therefore, may be longer than actual transfer of data to the used time of the transformation of CELL-DCH state, for example, in the time only having low volume data to transmit.
And, when in the process of UE in state being become to CELL_DCH state, must required state be changed and be addressed to UE by forward access channel (FACH), and FACH be considerably slower than HSDPA transmission channel after a while and robust more not.Before the transformation to CELL_DCH state and in process, CELL_FACH state need to by downlink-dedicated control channel (DCCH) and downlink-dedicated Traffic Channel (DTCH), the two be mapped on forward access channel (FACH).
May wish at UE in the state of other outside CELL_DCH time, realize HSDPA.For example, may be desirably in CELL_FACH state and realize HSDPA.In CELL_FACH state, realize HSDPA and can be called the HS-DSCH in CELL_FACH state, or common HS-DSCH.Be appreciated that and run through following discussion, these terms can exchange use.If realize HSDPA in CELL_FACH state, it may be useful defining the Frame Protocol being used by Iub and Iur interface and parameter and Node B application protocol (NBAP) and radio network system application protocol (RNSAP).The present invention solves can be for the Frame Protocol of the HS-DSCH in CELL_FACH state and parameter.But, be appreciated that and can realize the illustrative embodiments that the present invention discusses with any communications status known in the art or exploitation after a while.

Embodiment
With reference to multiple execution modes, in the mode of example, the present invention is described.The present invention describes in the context of cellular communication system and particularly HSDPA WCDMA/UMTS communication system.But, be appreciated that the present invention can be suitable for realizing equally in any communication system that realizes packet scheduling, particularly need to solve in the delay of data packet transfer and the communication system of spectrum efficiency problem and realize at those.
The communication system that embodiments of the present invention can realize therein can comprise at least one subscriber equipment (UE).Subscriber equipment can be for example mobile phone, but can be also laptop computer, personal digital assistant or any other suitable equipment that for example can communicate.
Subscriber equipment is wirelessly communicated by letter with a series of radio base stations (RBS) by radio.Radio base station in UMTS standard also referred to as Node B.In the following description, term " Node B " and " radio base station (RBS) " are used interchangeably.
Each subscriber equipment is arranged for communicating by letter with a more than RBS, and similarly, each RBS arranges for communicating by letter with a more than UE.RBS also communicates by letter with radio network controller (RNC) (its in GSM standard also referred to as base station controller (BSC)).RNC can also communicate by letter with core net (CN).Be appreciated that in the Long Term Evolution of 3GPP, may do not have central RNC, but the function of RNC is distributed to entities of various kinds or network element.CN can also communicate with other networks, and these networks are for example other public land mobile network (PLMN) or the computer network that is called " the Internet ".
Can realize in the following manner high-speed downlink packet access (HSDPA) communication.Subscriber equipment (UE) is upper to Serving RNC transmission radio resource controller (RRC) connection request message in Common Control Channel (CCCH) via selected community, thereby initiate the foundation of radio resource control connection, wherein selected community is the community of radio base station (RBS) (also, Node B).The reason that the parameter that this connection request comprises initial user equipment (UE) ident value and connection are set up.
The radio resource control (RRC) that service radio network controller (RNC) is established to this UE connects and determines that dedicated channel is used for to this specific RRC to be connected, and is that this radio resource control connection is distributed UTRAN (UMTS terrestrial radio access network) RNTI (radio net temporary identifier) and radio resource L1, L2.In the time will setting up dedicated channel, to RBS sending node B application protocol (NBAP) message, " radio link is set up request information.This radio link is set up the parameter comprising in request and is comprised: cell ID value, for the configuration parameter of DL DPCH or F-DPCH, the up link scrambler that will use (only for frequency division multiplexing (FDD) communication), time slot (only for time division multiplexing (TDD) communication), user code (only for TDD) and the power control information etc. that will use.
The reception of RBS Resources allocation, beginning uplink physical channel, and utilize Node B application protocol (NBAP) message (also, " radio link is set up response " message) to respond.Radio link setup response message is included as that Iub transfer of data carrier definition signaling link stops, transport layer addressing information (such as, ATM self-adaptive layout type 2 (AAL2) address, AAL2 binding logo) parameter.Service radio network controller uses Access Link Control Application Part agreement (ALCAP) to initiate the foundation of Iub transfer of data carrier.This request comprises AAL2 binding logo, to Iub transfer of data carrier is tied to dedicated channel.Setting up the request of Iub transfer of data carrier is confirmed by RBS.Alternatively, Internet protocol (IP) can be for transport layer, but not uses AAL2.
RBS and Serving RNC be for example, by means of the suitable dedicated channel frame protocol of exchange (, " downlink synchronization " message and " uplink synchronisation " message), sets up synchronizeing of Iub and Iur transfer of data carrier.After synchronous, RBS starts the downlink transmission to UE.
Send a message from Serving RNC to UE, this message is to connect and set up message at the upper radio resource controller (RRC) sending of Common Control Channel (CCCH).RRC connection is set up message and is comprised following parameter: initial UE ident value, U-RNTI (in CELL_FACH state and CELL/URA_PCH in UTRAN inner effectively), C-RNTI (effectively inner in CELL_FACH state Zhong community), ability update demand, TFS Transport Format Set, transport format combination set, frequency, down-link frequencies scrambler (only FDD), time slot (only TDD), user code (only TDD), power control information, and define in 3GPP standard TS25.331 part 10.2.40, be used for especially configuring other data that the upper signaling of HSDPA connects.
RBS realizes uplink synchronisation, and utilizes NBAP message (" radio link recovers instruction ") to carry out notification service RNC.Upper in Dedicated Control Channel (DCCH), via service, RBS is sent to Serving RNC by RRC connection setup complete message from UE.This RRC connection setup complete message comprises following parameter: integrity information, encrypted message and UE radio access capability.
When UE is in CELL_FACH state, also, in the HS-DSCH in CELL_FACH state or common HS-DSCH time, can use HSDPA.In the first aspect of exemplary embodiment of the invention, provide the Frame shown in Fig. 2.In the time only having a transport vehicle to realize the HS-DSCH in CELL_FACH state, can use this Frame.This Frame can also be with the Frame Protocol that acts on Iub interface.
The Frame of Fig. 2 for example can comprise H-RNTI (radio net temporary identifier) value in the payload part of this Frame.H-RNTI does not have effective C-RNTI (cell-radio network temporary identifier) or in the time that C-RNTI is invalid after cell reselection, is assigned to the public identifier value of subscriber equipment (UE) as UE.Can assign unique H-RNTI for each UE, it can be used for identifying the each expection recipient who has transmitted grouping who has been arranged in physical layer in the time that UE has effective C-RNTI, and dedicated H-RNTI can be got identical value with the effective C-RNTI that distributes to UE.H-RNTI value is included in the Frame shown in Fig. 2, thereby Node B for example can be identified at, for (passing through physical layer 1 (L1) transmit data frames, Frame shown in Fig. 2) in the HSDPA transmission period of data between, will use which H-RNTI.CRNC (control radio network controller) can arrange this H-RNTI value in Frame during the HS-DSCH in CELL_FACH state, and in the time carrying out conventional H SDPA transmission in community, this value can not be set.H-RNTI can be included in the spare extension part of Frame, and if be this situation, need to carry out corresponding change for new IE mark (New IE Flag).
The Frame of Fig. 2 for example can comprise U-RNTI (radio net temporary identifier) value in the payload part of Frame.Can during the HS-DSCH in CELL_FACH state, comprise U-RNTI, but do not comprise it in conventional H SDPA transmission.If U-RNTI is included in the spare extension part of Frame, correspondingly need to change new IE mark.
Frame shown in Fig. 2 can also comprise transmission power level (its can for the power control during the HS-DSCH in CELL_FACH state, in community), and for the adaptive modulation and coding of the HS-DSCH of CELL_FACH state.Can during the HS-DSCH in CELL_FACH state, comprise transmission power level, but do not comprise it between conventional H SDPA transmission period.If transmission power level is included in the spare extension part of Frame, may need correspondingly to change new IE mark.Be appreciated that in embodiments of the present invention, the form of transmission power level can be that channel quality information (CQI) is reported or is contained in wherein.Transmission power level is relevant with channel quality, or can be the designator of channel quality.Therefore, be appreciated that the object for power control, scheduling of resource and adaptive modulation and coding, transmission power level and channel quality information can be configured, to realize identical object.
Frame shown in Fig. 2 can also comprise MAC-d/c PDU length field.If Frame is the expansion of existing HS-DSCH Frame, MAC-d PDU length field can be renamed to the length into MAC-d/c PDU.MAC-d/c PDU length field allows Node B: if adopted the HS-DSCH in CELL_FACH state, this field is considered as to MAC-c PDU length or MAC-d PDU length; If adopted conventional H SDPA, this field is considered as to MAC-d PDU length.
Frame shown in Fig. 2 also comprises MAC-d/c PDU.If Frame is the expansion of existing HS-DSCH Frame, MAC-d PDU field can be renamed to the PDU into MAC-d/c.MAC-d/c PDU allows Node B: if adopted the HS-DSCH in CELL_FACH state, this field is considered as to MAC-c PDU or MAC-d PDU; If adopted conventional H SDPA, this field is considered as to MAC-d PDU.
Frame shown in Fig. 2 can also comprise new H-RNTI designator (being expressed as NH in Fig. 2) at the spare part of data frame header.In alternative, can be by Flush (washing away) field as new H-RNTI designator.NH designator can be used for showing: the UE that H-RNTI value had previously been distributed from this value has distributed to new or different subscriber equipmenies (UE).If adopted the HS-DSCH in CELL_FACH state, CRNC arranges new H-RNTI value, but between conventional H SDPA transmission period, this value is not set.If new H-RNTI is made as 0, Node B is by using the quality information of memory channel (CQI) of this H-RNTI, to transmit the HS-DSCH data in CELL_FACH state by air interface.If new H-RNTI value is made as 1, Node B will be washed away the CQI of the storage information of this H-RNTI, and restarts to operate for the CQI of H-RNTI washing away after storing CQI information.New H-RNTI can be for the power control based on CQI report.
Frame shown in Fig. 2 can also comprise CmCH-PI/ logic channel ID.CmCH-PI represents Common transport channel priority indicator.If Frame is the expansion of existing HS-DSCH Frame, can be by CmCH-PI field RNTO CmCH-PI/ logic channel.If adopted the HS-DSCH in CELL_FACH state, Node B can be considered as this value logic channel ID.The priority being associated with logic channel ID can be pre-configured in Node B based on Node B application protocol (NBAP), and Node B can be carried out operation dispatching based on this information.Between conventional H SDPA transmission period, this value is considered as CmCH-PI by Node B.
In the second aspect of the illustrative embodiments of discussing with reference to figure 2 above, H-RNTI value is not must be arranged in the spare extension of Frame.For the specific H-RNTI of UE, H-RNTI value must arrange in Frame, and only new H-RNTI designator (NH) is set in Frame during the specific H-RNTI of UE.
Frame shown in Fig. 2 can be for layer 2 (L2) protocol Data Unit (PDU).For example, the Frame of Fig. 2 can be used for carrying the PDU structure shown in Fig. 3 A.The Frame of Fig. 2 can also be used to carry the PDU structure shown in Fig. 3 B, and this PDU structure is at common unsettled U.S. Provisional Application No.60/852, discusses in detail in 331, by reference it is incorporated to completely at this.PDU shown in Fig. 3 B can carry in the execution mode of the Frame of Fig. 2, and wherein the execution mode of this Frame is the HS-DSCH Frame of expansion.In the case, Node B or drift radio network controller (DRNC) can be considered as logic channel ID by CmCH-PI/ logic channel ID.
Be appreciated that the Frame Protocol shown in Fig. 2 can be implemented as new Frame Protocol, or be embodied as the expansion of existing the 6th edition HS-DSCH Frame Protocol.If the Frame Protocol of Fig. 2 is embodied as expansion, by allow with identical Frame Protocol support HSDPA in CELL_DCH state and CELL_FACH state the two.No matter be further appreciated that how the Frame Protocol of Fig. 2 is realized, information required in Frame Protocol will be identical.Be further appreciated that the Frame Protocol back compatible shown in Fig. 2 the 6th edition and the 5th edition HS-DSCH Frame.
