Description
Technical field
The present invention relates to mobile communication, be specifically related to a kind of high-speed uplink packet access method of multicarrier system.
Background technology
(1) in order to satisfy the growing demand of user to the high-speed upward grouped data business, support to higher quality of service also is provided in order to match with high-speed downlink packet access High Speed Downlink Packet Access (being called for short HSDPA) technology better, 3GPP inserts High Speed Uplink Packet Access (being called for short HSUPA) technology in the High Speed Uplink Packet that Rel6 and Rel7 have introduced based on Wideband Code Division Multiple Access (WCDMA) Wideband Code Division Multiple Access (being called for short WCDMA) system and TD SDMA Time Division Code SynchronizationDivision Multiple Access (being called for short TD-SCDMA) system respectively, perhaps is referred to as dedicated channel Enhanced Dedicated Channel (the being called for short E-DCH) technology of up enhancing Enhanced Uplink or enhancing.HSUPA adopt to mix automatic repeat requests HARQ, high order modulation (16QAM), node Node B fast dispatch and based on the technology such as reverse RoT control of T/P, can obtain higher user's peak rate, cell data throughput and reach stable reverse RoT to control.
(2) HSUPA has inherited technology such as HARQ, fast dispatch from HSDPA, and has increased the distinctive Enhanced Technology of some ul transmissions on this basis.HSUPA has adopted the asynchronous HARQ mode of incremental redundancy (IR), merges and coding gain by obtaining to retransmit, and improves systematic function.The mode that retransmission mechanism is also the same with HSDPA have been adopted that the N channel stops and wait.
Physical layer carrying aspect, HSUPA has introduced new Physical Shared Channel E-PUCH and has carried corresponding transmission channel E-DCII.Simultaneously, in order to finish control corresponding, scheduling and feedback, HSUPA has introduced E-RUCCH, E-AGCH and three physical control channels of E-HICH in physical layer.Wherein the terminal UE that is used under the CELL_DCH state of E-RUCCH is not having under the situation of resource authorization request authorize to carry out transfer of data, its transmission means is the access way of preemptive type, process is identical with Physical Random Access Channel PRACH, and can share physical code channel with PRACH.For the current UE that mandate is arranged, also the multiplexing Node B that passes in the MAC-e of E-PUCH PDU of schedule information that can UE is current (SI) is to reach the purpose of dispatch request.Schedule information (SI) comprises: information such as power headroom, path loss, buffer size.
E-AGCH is used for Node B and transmits the scheduling resource authorization message to UE, and it comprises following physics control information: power authorization message, time slot authorization message, code channel authorization message, interim user network identity, the number of E-UCCH, the indication of resource continuous time, E-DCH cyclic sequence number, the indication of E-HICH channel etc.
E-HICH is used for Node B and feeds back the ACK/NACK information of each transmission block to UE, and in order to reduce the physical channel expense, E-HICH has adopted the mode of secondary spread spectrum, can be implemented in maximum 80 the signature users of carrying on the original physical code channel.The user's signature sequence is related with the resource dynamic of distribution simultaneously, can satisfy the demand of supporting that the Large Volume Data user is simultaneously online.
UE is set up/distributed to when reshuffling to the E-AGCH channel by RNC at radio bearer.E-AGCH manages in the mode of gathering and distributes, and a UE can distribute a set, and a set can comprise 1～4 E-AGCH physical channel.UE monitors all E-AGCH channels, and each time interval TTI (5ms) identifies relevant scheduling authorization information on maximum 1 the E-AGCH channel that read wherein according to UE, to carry out the E-PUCH channels transmit.
A sub-district can dispose many E-HICH physical channels.RNC sets up/distributes to when reshuffling UE1～4 an E-HICH physical channel at radio bearer.During concrete the use, each TTI gives UE by NodeB by wherein 1 of E-AGCH dynamic assignment.
HSUPA has introduced MAC-e/MAC-es sublayer (entity) at the media access control MAC layer of UE and Node B/RNC, finishes functions such as relevant scheduling, processed, feedback, re-transmission.Directly provide at network side resource authorization and ACK/NACK feedback, can improve the speed of scheduling and transmission/re-transmission significantly, reduce the whole time delay of transfer of data by the MAC-e sublayer that is positioned at Node B; Network side MAC-es sublayer is positioned at RNC, is used to guarantee the transmission according to the order of sequence of packet.In addition, in the UE side, each TTI of UE (5ms) carries out E-TFC according to current authorization message with the benchmark E-PUCH power that is subjected to the base station closed-loop control and selects, and selects suitable transmission block size and modulation system (modulation system and transmission block size implicit associations).
Except based on the transmission means of authorizing, i.e. scheduled transmission, it is professional and guarantee the qos requirement of rate business that the transmission that HSUPA has also introduced non-scheduling solves delay sensitive.The dispatch request, wireless propagation environment He Lin district that the resource of scheduled transmission is taken all factors into consideration all UE by Node B disturbs factor such as inhibitions to distribute in real time, this scheduling mode relatively be suitable for those sudden strong, flowed fluctuations greatly, to the insensitive business of time delay; But not the scheduling mode be the transmission resource by the semi-static in advance distribution of RNC, this mode is fit to the type of service senses quicker to time delay such as SRB, GBR.From the horizontal direction of carrying, the correlated resources of these two kinds of scheduling modes, as the HARQ entity, separate.The single carrier wave of each UE allows 8 HARQ processes at most, and wherein scheduled transmission and non-scheduled transmission account for 4 respectively.
(3) below, the HSUPA technical method step in the present single carrier TD-SCMDA system further is summarized as follows:
1. for scheduled transmission:
1, E-PUCH, E-AGCH and E-HICH physical channel are configured on the single carrier wave;
2, be that a UE distributes E-AGCH and E-HICH physical channel resources pond on single carrier wave;
3, at single carrier,, be that a UE sets up a MAC-e/MAC-es entity in the MAC-e/MAC-es sublayer; E-DCH transmission data are mapped on the E-PUCH physical channel resources of this single carrier by this MAC-e/MAC-es entity;
4, Node B gives UE by the E-PUCH physical channel resources on this single carrier of E-AGCH dynamic dispatching mandate;
5, feeding back ACK/nack message on an E-HICH channel on this single carrier.
2. for non-scheduled transmission:, transmit relevant resource and use this resource to carry out non-dispatch E-DCH transmission by the non-dispatch E-DCH of RNC static allocation on this single carrier at each UE;
3. time interval TTI, UE dispatches or non-scheduled transmission.
(4) especially, for the above-mentioned TD-SCDMA HSUPA of system technology, adopt the TDD single carrier operation mode of relative arrowband, i.e. carrier wave in a sub-district, theoretical peak speed based on QPSK can reach 1.1Mbps, and can reach 2.2Mbps (relevant details can with reference to 3GPP) based on the theoretical peak speed of 16QAM.If the HSUPA technology is incorporated in the multi-carrier TD-SCDMA system, then can further improve the applicability of the throughput and the HSUPA technology of HSUPA technology in the TD-SCDMA system.Multi-carrier TD-SCDMA system has following characteristics: in multi-carrier TD-SCDMA system, and a plurality of carrier waves that the sub-district comprises.A carrier wave in a plurality of carrier waves is a main carrier, and other carrier wave is auxilliary carrier wave, only sets up and use all or part of common signal channel on main carrier.Therefore, if use the HSUPA technology in multi-carrier TD-SCDMA system, then can carry out the HSUPA transmission on a plurality of carrier waves (N carrier wave) of a sub-district, the up N that can obtain of one side is doubly to the throughput of single carrier HSUPA; Also possible on the other hand N doubly improves the peak rate of single terminal.But, do not have the HSUPA technology implementation method of utilizing a plurality of carrier waves in multicarrier TD-SCMDA system at present, so the HSUPA transmission rate is on the low side.

At first, basis of the present invention is described:
Based on single carrier HSUPA, the same with the HSUPA technology of single-carrier cell in multi-carrier district, upstream data service sends by the E-DCH transmission channel; The MAC layer comprises a MAC-e/MAC-es sublayer, finishes functions such as relevant scheduling, processed, feedback, re-transmission; Transmission channel E-DCII is mapped on the E-PUCH physical channel, and the scheduling authorization information that the E-PUCH physical channel is relevant sends by E-AGCH, uses E-HICH to come feeding back ACK/nack message.
Secondly, key of the present invention is described: single carrier HSUPA scheduled transmission method and non-scheduled transmission method are transformed, and the inventive method is specific as follows:
(1) for scheduled transmission:
1, on one or more carrier waves, dispose E-PUCH, E-AGCH and E-HICH physical channel resources simultaneously;
2, be that a UE distributes one or more E-PUCH physical channel carrier resource, and on this one or more carrier wave, distribute one or more of E-AGCH and E-HICH physical channel simultaneously, E-AGCH on the same carrier wave and E-HICH physical channel are associated, and are associated with E-PUCH physical channel resources on the same carrier wave;
3, in the MAC-e/MAC-es sublayer, be that a UE sets up a MAC-e/MAC-es entity; This entity is shared by a plurality of carrier waves, but wherein gets each the carrier wave separate configurations of process in the HARQ entity; Dispatch E-DCH transmission data dynamically are mapped on one or more carrier wave by this MAC-e/MAC-es entity;
4, Node B gives UE by the E-PUCH physical channel resources that the E-AGCH dynamic dispatching authorizes on the carrier wave that this E-AGCH is associated;
5, at each carrier wave, Node B feeds back the reception condition of the E-DCH transmission of this carrier wave, i.e. ACK/NACK information on an E-HICH channel on the same carrier wave that is associated with E-AGCH.
(2) for non-scheduled transmission: at each UE, distribute a carrier resource by RNC, and employing and the identical method of the single carrier TD-SCMDA HSUPA of system technology, on this carrier wave, distribute and use the relevant resource of non-dispatch E-DCH transmission to carry out non-dispatch E-DCH and transmit;
Simultaneously, a TTI, UE dispatch and/or non-scheduled transmission.
At last, describe the inventive method in detail in conjunction with instantiation in the multi-carrier TD-SCDMA system:
In multi-carrier TD-SCDMA system, if set up a multi-carrier district (method for building up of multi-carrier district can referring to communication industry standards such as " 2GHz TD-SCDMA digital mobile cellular telecommunication net height speed downlink grouped insert the specification requirement of (HSDPA) Iub interface "), comprising N carrier wave, as shown in Figure 1, realize in this multi-carrier district that then above-mentioned HSUPA method comprises:
(1) to scheduled transmission:
1, dispose E-AGCH, E-PUCH and E-HICH physical channel resources on one or more carrier wave in multi-carrier district simultaneously.
In this process, to compare with the corresponding physical channel in the HSUPA technology in the single carrier TD-SCDMA system, the E-AGCH of configuration, E-PUCH and E-HICH physical channel structure are just the same.Interrelated in order to realize E-PUCH, E-AGCH and E-HICH physical channel on the same carrier wave, need guarantee on same carrier wave, to dispose simultaneously one or more of E-PUCH, E-AGCH and E-HICH physical channel resources.
At network side, press existing network infrastructure, be that wireless network is made up of RNC and two network elements of Node B, and RNC is connected by Iub interface with Node B, and then this process can be initiated that Physical Shared Channel (the Physical SharedChannel Reconfiguration) process of reshuffling realize in the NBAP agreement by RNC to Node B by Iub interface.In " PHYSICAL SHARED CHANNELRECONFIGURATION REQUEST " message, be configured in the information in E-PUCH and E-HICH and E-AGCH physical channel resources pond, comprise its carrier wave attribute information, to indicate the carrier frequency attribute of these physical channels, dispose E-PUCH and E-HICH and E-AGCH physical channel resources pond on a plurality of carrier waves thereby be implemented in.If the wireless network of network side has only network element of Node B, then this process cooperatively interacts between can the correlation function module by Node B inside and realizes.
In this process, as shown in Figure 3, in Node B, set up an E-DCH scheduling entity simultaneously and manage these carrier waves and physical channel resources thereof.
2, RNC and/or Node B are that a UE distributes one or more E-PUCH physical channel carrier resource, and distribute one or more of E-AGCH and E-HICH physical channel resources on this one or more carrier wave simultaneously.
In a multi-carrier district, when RNC and/or Node B are defined as a UE and distribute the E-PUCH resource to carry out the E-DCH transmission, with HSUPA technology type in the single carrier TD-SCDMA system seemingly, RNC and/or Node B need be that a UE divides E-AGCH and the E-HICH physical channel resources pond that is used in the relevant control signaling transmission of one or more carrier wave by high-level signaling.
At RNC and/or Node B is when a UE distributes E-AGCH and E-HICH physical channel resources pond, the carrier resource that has also distributed the E-PUCH physical channel, promptly all dispose in the carrier wave of E-PUCH physical channel resources at this multi-carrier district, may distribute the carrier resource of E-PUCH physical channel resources thereon for this UE, because the E-PUCH on the same carrier wave, E-AGCH and E-HICH physical channel are to be mutually related.RNC and/or Node B need to consider that the up and/or descending carrier of UE and physical channel receive and/or emissivities when distributing and using these resources subsequently, therefore, in the related higher-level signaling in this process, also need to carry the relevant information of UE ability.
Particularly, at network side, press existing network infrastructure, usually be defined as a UE and carry out the E-DCH transmission and initiate Radio Link in the NBAP agreement by Iub interface to Node B and set up process and realize distributing and the relevant resource of dispatch E-DCH transmission with wireless links reconfiguration course by RNC.Usually, come to distribute E-AGCH and E-HICH physical channel resources pond by Node B for UE, comprising the distribution of these physical channel carrier wave attributes, and set up response RADIO LINKSETUP RESPONSE or radio link reconfiguration by Radio Link and be ready to complete RADIO LINKRECONFIGURATION READY message and send to RNC.And E-PUCH physical channel carrier resource can be distributed by RNC or Node B.If distribute E-PUCH physical channel carrier resource, then set up and ask RADIO LINK SETUPREQUEST or radio link reconfiguration to prepare to comprise and the relevant indication information of E-PUCH physical channel carrier resource in the RADIO LINK RECONFIGURATIONPREPARE message at the Radio Link that sends to Node B by RNC.And Node B can only be on each carrier wave of this indication information indication, for UE distributes E-AGCH and E-HICH physical channel resources pond.If distribute E-PUCH physical channel carrier resource by Node B, then setting up response RADIO LINK SETUP RESPONSE or radio link reconfiguration at Radio Link is ready to complete in the RADIO LINK RECONFIGURATION READY message and comprises and the relevant indication information of E-PUCH physical channel carrier resource, normally the carrier wave attribute by E-AGCH and E-HICH physical channel comes the implicit expression indication, because E-AGCH must be distributed on the E-PUCH physical channel carrier resource place carrier wave related with it with the E-HICH physical channel.If the wireless network of network side has only network element of Node B, then this process cooperatively interacts between can the correlation function module by Node B inside and realizes.
RNC and/or Node B send to UE with the relevant resource of dispatch E-DCH transmission of above-mentioned distribution by high-level signaling.Press existing network infrastructure, this process is connected the process of foundation (RRC connectionestablishment) by the RRC that RNC initiates in the RRC agreement to UE by Uu interface (interface between network side and UE), radio bearer is set up process (radio bearer establishment), radio bearer reconfiguration course (radio bearer reconfiguration), radio bearer dispose procedure (the radio bearerrelease), transmission channel reconfiguration course (transport channel reconfiguration), physical channel reconfiguration course (physical channel reconfiguration), cell updating course processes such as (cell update) realizes, at corresponding " RRC CONNECTION SETUP ", " RADIO BEARERSETUP ", " RADIO BEARER RECONFIGURATION ", " RADIO BEARERRELEASE ", " TRANSPORT CHANNEL RECONFIGURATION ", " PHYSICAL CHANNEL RECONFIGURATION ", the configuration information that comprises dispatch E-DCH transmission related resource in " CELL UPDATECONFIRM " message wherein comprises the carrier wave attribute information of physical channel in the physical channel configuration information.If the wireless network of network side has only network element of Node B, then transmit relevant resource allocation information to UE by sending E-DCH with similar process of said process and message by Node B.
3, in the related resource that is UE allocation schedule E-DCH transmission, set up a MAC-e/MAC-es entity respectively at network side and UE side.This entity is shared by a plurality of carrier waves, but is respectively each carrier wave separate configurations HARQ process.
Identical with the HSUPA technology in the above-mentioned single-carrier system, need in the Node of network side B/RNC, set up a MAC-e/MAC-es entity respectively for each UE in the MAC-e/MAC-es sublayer with UE inside, with other related entities, as the E-DCH scheduling entity, finish functions such as relevant scheduling, processed, feedback, re-transmission.As shown in Figures 2 and 3, this MAC-e/MAC-es entity is that a plurality of carrier waves are shared.But in the MAC-e/MAC-es entity, need be each carrier wave separate configurations HARQ process, each carrier wave is identical with HSUPA technology in the single carrier TD-SCDMA system, and each carrier wave allows 8 HARQ processes at most, and wherein scheduled transmission and non-scheduled transmission account for 4 respectively.In the UE side, the E-TFC in the MAC-e/MAC-es entity selects entity and/or scheduling access control entity, each carrier wave separate configurations corresponding entity or shared entity of all carrier waves configuration.At network side, if wireless network is made up of RNC and two network elements of Node B, then the MAC-e entity is positioned at Node B, and E-DCH wherein controls each carrier wave separate configurations corresponding entity or shared entity of all carrier waves configuration; And the MAC-es entity is positioned at RNC, compares with the HSUPA technology of single carrier TD-SCDMA system, and MAC-es entity and functional entity thereof are identical; And if wireless network has only network element of Node B, then the MAC-e/MAC-es entity all is arranged in Node B.
4, Node B is used for the E-DCH transfer of data by the E-PUCH physical channel resources that one or more of E-AGCH dynamic dispatchings authorize on one or more carrier wave that these E-AGCH are associated to UE.In the UE side, E-DCH transmission data dynamically are mapped to by the MAC-e/MAC-es entity on the E-PUCH physical channel of one or more carrier wave of mandate; At the NodeB of network side, on the E-PUCH physical channel of one or more carrier wave of authorizing, receive the E-DCH data.
Certain TTI, if Node B determines to authorize UE to carry out the E-DCH transmission, then Node B is according to the resource distribution situation in the step 2, from the E-PUCH carrier resource of configuration, select one or more carrier wave, on each carrier wave, distribute the E-PUCH physical channel resources respectively, and by an E-AGCH channel that is associated with each carrier wave the E-PUCH physical channel resources on each carrier wave is licensed to UE and be used for the E-DCH transfer of data.
In the UE side, certain TTI, according to the authorization message that receives from one or more of E-AGCH channels, E-DCH transmission data are shunted and are mapped in the MAC-e/MAC-es sublayer on the E-PUCH physical channel on one or more carrier wave of mandate; And at network side, on the E-PUCH physical channel on the carrier wave on one or more carrier wave of authorizing, receive the E-DCH data and merge.Wherein the E-DCH data map process on each carrier wave comprises the physical layer correlation procedure, and is identical with the HSUPA technology in the single carrier TD-SCDMA system.
In this process, for the carrier wave of the E-PUCH physical channel of each mandate, used E-AGCH physical channel is one that selects in the E-AGCH physical channel resources pond of distributing for UE from step 2 that is associated with this carrier wave.Generally, after UE has been assigned with the relevant physical channel resources of above-mentioned E-DCH transmission, UE need monitor in step 2 all the E-AGCH physical channels in the E-AGCH physical channel resources pond on all carrier waves that distribute, and, at each carrier wave, search for to identify by " UE sign " on the E-AGCH channel and really distribute to the E-AGCH channel that this UE uses.At network side, at each carrier wave, Node B only need select one and be used for sending the relevant scheduling authorization information of this carrier wave from that distribute and E-AGCH physical channel resources pond that this carrier wave is associated for UE.
Carrier wave at the E-PUCH physical channel of each mandate, Node B dispatches distribution E-PUCH physical channel resources by the E-AGCH related with it to UE when, the E-HICH channel that is positioned on the same carrier wave that Node B uses when also sending ACK/NACK subsequently by the E-HICH indication information on this E-AGCH indication, identical in the HSUPA technology in its indicating means and the single carrier TD-SCDMA system.
5, each is carried out the carrier wave of E-DCH transmission, Node B gives UE by the reception condition that an E-HICH physical channel on the same carrier wave feeds back E-DCH transmission on this carrier wave.
Carrier wave at the E-PUCH physical channel of each mandate, according to the E-HICH physical channel configuring condition in the step 2, Node B selects an E-HICH channel and gives UE by the reception condition of this channel feedback E-DCH transmission subsequently on this carrier wave, by the E-HICH indication information on the E-AGCH channel on this carrier wave the E-HICH physical channel of selecting is indicated to UE.In the UE side, carrier wave at the E-PUCH physical channel of each mandate, according to the E-HICH channel indicating information on the E-AGCH channel that receives on the E-HICH physical channel configuring condition in the step 2 and this carrier wave, receive the E-HICH physical channel, and then the reception condition information of the E-DCH transmission of this carrier wave of reception Node B feedback, i.e. ACK/NACK information.
(2) to non-scheduled transmission:
At each UE, distribute one or more carrier resource by RNC, and on these carrier waves, adopt the non-dispatch E-DCH transmission relevant resource allocation methods identical to distribute related resource and use this resource to carry out non-dispatch E-DCH transmission with the single carrier TD-SCMDA HSUPA of system technology;
(3) TTI, UE dispatches and/or non-scheduled transmission.
Certain TTI, if UE only has been assigned with scheduling or non-scheduling E-PUCH physical channel resources, then UE uses scheduling or non-scheduling E-PUCH physical channel resources to dispatch or non-scheduled transmission on corresponding carrier wave.
Certain TTI, if UE has been assigned with the E-PUCH physical channel resources of scheduling and non-scheduling simultaneously, and the E-PUCH physical channel resources of scheduling and non-scheduling is on different carrier waves, then UE can selection scheduling or the E-PUCH physical channel resources of non-scheduling dispatch or non-scheduled transmission, also can use scheduling and non-scheduling E-PUCH physical channel resources to dispatch simultaneously and non-scheduled transmission.
