Description
Technical field
The present invention relates to field of wireless communication, relate in particular to the distribution method that a kind of HS-SCCH-less of application operates HS-SICH channel when transmitting HS-DSCH.
Background technology
HSPA (high-speed packet access) comprises 2 big technology in 3GPP (3G (Third Generation) Moblie partnership) protocol architecture, the i.e. HSDPA that in the Rel-5 version, formulates (HighSpeed Downlink Packet Access, high speed downlink packet inserts) technology and E-DCH (enhancing dedicated channel) technology in the Rel-6 version, formulated, be commonly referred to HSUPA (HighSpeed Uplink Packet Access, high speed uplink packet inserts) technology.The introducing of HSPA technology makes 3GPP 3G (Third Generation, the third generation) grouping of network service bearer ability strengthen greatly, and the availability of frequency spectrum also is significantly improved.With TD-SCDMA (TD SDMA) system is example, HSDPA can provide the downlink data throughput of the highest 2.8Mbps, its feature comprises: utilize 5ms TTI (Transmission Time Interval), adaptive coding and modulating (AMC), mix retransmit (HARQ) automatically, based on key technologies such as the scheduling of Node B (base station) and shared channels, HSDPA can the fast adaptation wireless environment variation, dynamically adjust the down link data throughput; By transferring Traffic Channel to " sharing " from " special use ", make more user share descending wireless bandwidth, effectively improved wireless resource utility efficiency.
When carrying out the HSDPA transmission, network side disposes one group of HS-SCCH (at a high speed-shared control channel) channel and HS-SICH (at a high speed-share indicating channel) channel (comprising maximum 4 couples of HS-SCCH and HS-SICH channel in this group channel) and H-RNTI (high speed descending sharing channel-Radio Network Temporary Identifier) for UE in advance when setting up the relevant radio bearer of descending HS-DSCH (at a high speed-DSCH Downlink Shared Channel) for UE.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 by the H-RNTI on the identification HS-SCCH whether this transmission is sent to oneself.In case detected the HS-SCCH channel that is sent to oneself, read the information on the HS-SCCH channel, concrete signaling content on the HS-SCCH as shown in Figure 1, this signaling format Class1 (type 1) that is otherwise known as, wherein code channel and gap information indication UE is about to HS-PDSCH (high speed down sharing physical channel) channel resource that receives; Modulation system and transport block length indication transformat.Behind predetermined timing time nHS-SCCH, UE receives data on the HS-PDSCH of appointment channel, and on the HS-SICH of correspondence channel, carrying out HARQ (mixing automatic repeat requests) feedback and CQI (Channel Quality Indication, channel quality indication) report behind the timing nHS-SICH of appointment.The schematic diagram of a HS-DSCH transmission as shown in Figure 2.
In Rel-7, WCDMA (Wideband Code Division Multiple Access (WCDMA) access) system has finished the standardization effort that the continuity grouping connects (Continuous Packet Connectivity is called for short CPC) project based on the HSPA technology.The upstream noise that CPC is intended to reduce control channel strip when keeping the user to connect continuously raises, and promotes the grouping user quantity that connects when keeping long.The operation thought of HS-SCCH-less wherein, has been proposed at the typical services VoIP (Voice overIP, IP phone) in the broadband packet business.In the HS-SCCH-less operation, be QPSK (orthogonal PSK) at single UE preassignment 1-2 bar HS-PDSCH code channel, maximum 4 kinds of transport block length and fixed modulation mode by SRNC.The same with former HSDAP system, UE still need monitor maximum 4 HS-SCCH channels.The concrete feature of HS-SCCH-less operation comprises:
HS-PDSCH transmission does not first have the HS-SCCH that follows, and UE carries out blind decoding at maximum 2 HS-PDSCH code channels, 4 kinds of possible transformats of high level configuration; The H-RNTI information that comprises UE among the CRC of HS-PDSCH (cyclic redundancy check (CRC)), UE judges by this field whether this time HS-PDSCH transmission sends to oneself; UE successfully decodes needs to send ACK (affirmation) behind the HS-PDSCH, and unsuccessful decoding does not need to send NACK (not confirming).
During re-transmission, Node B need send HS-SCCH, wherein signaling format and type1 are different, the information of wherein carrying comprises: HS-PDSCH channel code (maximum 2) and transport block length, be retransmit first or retransmit for the second time, the time indicator during the former transmission of same packets so that merge.Whether UE issues oneself by the identification of the H-RNTI among the HS-SCCH.When retransmitting, UE need reply ACK/NACK message.
It is consistent with original system that the timing relationship of HS-SCCH, HS-PDSCH, HS-SICH keeps.
Under the HS-SCCH-less operation, the HS-SCCH signaling format is called HS-SCCH type 2 (type 2).In a TTI, UE may receive the HS-SCCH of type 1 type, also may receive the HS-SCCH channel of type 2 types, is detected automatically by UE.
In real system, the success rate that the HS-DSCH data block is transmitted first is more than 90%, thereby do not send the HS-SCCH channel first and will save the downlink signaling expense greatly, and this saving amount is very considerable with respect to the business of this small data quantity of VoIP.The TD-SCDMA system also considers similarly to strengthen.There are being difference in TD-SCDMA system and WCDMA system aspect the HS-DSCH transmission, are dedicated channels such as uplink HARQ feedback channel in the WCDMA system, and UE fixedly takies a channel and carries out ascending HARQ feedback and periodic CQI report; And in TD-SCDMA, uplink feedback channel HS-SICH is a shared channel, and UE is assigned maximum 4 HS-SICH channels, and every HS-SICH channel all is associated with a HS-SCCH channel.When UE detects a HS-SCCH channel and is sent to oneself in a TTI, behind the HS-PDSCH that receives subsequently, reply HARQ information and CQI information on the HS-SICH channel of this HS-SCCH channels associated of Ying Zaiyu.When the service application HS-SCCH-less to VoIP and so on operates, do not send HS-SCCH first and will cause UE can't determine on any bar HS-SICH channel, to reply.Because the HS-SICH channel is the shared resource sub-district in, UE chooses at random a channel answer and may cause and the conflicting of other UE.Thereby when introducing the HS-SCCH-less operation, how UE selects the HS-SICH channel is TD-SCDMA system urgent problem.
Therefore, need a kind of solution of under the HS-SCCH-less operation, distributing high speed-shared indicating channel, can solve the problem in the above-mentioned correlation technique.

Be that example describes one embodiment of the present of invention in detail with reference to Fig. 5 and Fig. 6 and with the TD-SCDMA system below.
When the high-rise decision of network side is enabled the HS-SCCH-less operation for UE, be one or more groups HS-PDSCH channel resource of UE preassignment, comprise the required HS-PDSCH channel resource of a HS-DSCH transmission (that is HS-DSCH TTI transmission) in every group of channel resource.Distribute simultaneously and a corresponding HS-SICH channel of each group HS-PDSCH channel resource, a kind of method of salary distribution sees Table 1.
The configuration of table 1 HS-PDSCH and HS-SICH channel
| Information element | Essential | Type | Explain |
| The HS-PDSCH resource information | 1..maxHS-PDSCH group | MaxHS-PDSCHgroup: maximum HS-PDSCH resource group numbers that distribute | |
| The definition of HS-PDSCH channel | 1..maxHS-PDSCH | MaxHS-PDSCH: the HS-PDSCH number of channel in every group | |
| The HS-PDSCH channel | Essential | The physical channel definition | The channel definition comprises: frequency, timeslot number, code channel, intermediate code. |
| The HS-SICH channel | Essential | The physical channel definition | The channel definition comprises: frequency, timeslot number, code channel, intermediate code. |
In the table 1, the network side high level can distribute the HS-PDSCH channel resource of maximum maxHS-PDSCHgroup groups, one group of HS-PDSCH channel resource and a HS-SICH channels associated for UE; Distribute maxHS-PDSCH bar HS-PDSCH channel in every group of HS-PDSCH channel resource at most, the number of channel is looked a data quantity transmitted by the network side high level and is determined.
Under the HS-SCCH-less pattern, the transmission first of a data block does not send the HS-SCCH channel, and UE needs all HS-PDSCH channels of the high-rise configuration of blind Detecting, thereby HS-PDSCH group number is unsuitable too many, and the general value of maxHS-PDSCHgroup is 1 or 2.The number of channel in every group is decided according to the data volume of a HS-DSCH transmission, and concerning the VoIP business, because data volume is not very big, generally once transmission needs 1 to 2 channel, thereby maxHS-PDSCH is 1 or 2.The HS-SICH channel is that a spreading factor is 16 channel.
Network side also is required to be UE distribution H-RNTI, HS-SCCH channel and corresponding with it HS-SICH channel in addition, so that the HS-DSCH that sends when retransmitting or be used under the general mode transmits (general mode: the HS-DSCH under the non-HS-SCCH-less operator scheme sends), this method of salary distribution is identical with existing system.
In a TTI, UE detects the HS-PDSCH channel in all preallocated HS-PDSCH resource groups, judge by the H-RNTI information in the crc field wherein whether transmission is sent to oneself, transmit (promptly if be sent to the HS-PDSCH of oneself, the H-RNTI that comprises UE in the crc field), UE uses the HS-SICH channel related with this HS-PDSCH channel group to carry out the HARQ feedback.According to a data transfer schematic diagram of present embodiment as shown in Figure 6, hypothesis UE is operated under the HS-SCCH-less operator scheme in this flow process, and a HS-DSCH transmission takies 2 HS-PDSCH channels, the timing relationship of the interchannel that do not draw among the figure;
Whether step S602, UE detect in a TTI HS-SCCH or the HS-PDSCH transmission that is sent to oneself, comprises the H-RNTI information of this UE among the CRC in this example on this group of hypothesis HS-PDSCH channel;
Step S604, UE receive the data on this group HS-PDSCH channel, decode successfully after, with HS-SICH channel that this group HS-PDSCH channel is associated on feeding back ACK (affirmation);
Step S606, in a new TTI, UE has detected the HS-PDSCH transmission that is sent to oneself;
Step S608, any response is not returned in UE decoding failure; Node B retransmits these data, informs that by the HS-SCCH channel UE retransmits resource;
Step S610, UE receives data retransmission;
Step S612, UE is feedback acknowledgment information on the HS-SICH channel related with this HS-SCCH.
The HS-PDSCH channel and the HS-SICH channel that are distributed for the HS-SCCH-less operation still exist as shared resource, and the UE in the sub-district can share these resources by time division multiplexing mode.These HS-PDSCH channels and HS-SICH channel can exist in each subframe, their addressing system as previously mentioned: UE discerns this transmission by the H-RNTI among the CRC on the HS-PDSCH channel and whether is sent to oneself; UE uses the timing relationship of existing system definition, behind nHS-SICH the time slot with the HS-SICH of this HS-PDSCH channels associated on carry out HARQ and feed back.
Because HS-SICH is a shared resource, need guarantee can not clash when UE uses in the sub-district.When HS-PDSCH and HS-SICH resource were only shared between the UE under the HS-SCCH-less operator scheme, the UE that the fixedly timing relationship between HS-PDSCH and the HS-SICH can guarantee to share same HS-PDSCH resource and HS-SICH resource can not clash when operating under method of the present invention.Be the timing relationship schematic diagram between HS-PDSCH and the HS-SICH in the existing system as shown in Figure 5, nHS-SICH be in once transmitting (promptly, among HS-DSCH TTI) the last item HS-PDSCH channel (implication of the last item channel: in one group of HS-PDSCH channel among TTI, a timeslot number and an all maximum HS-PDSCH channel of sign indicating number Taoist monastic name) and HS-SICH between slot offset value, in the existing system, nHS-SICH 〉=9 time slot.Press the Typical Disposition mode of TD-SCDMA uplink and downlink time slot transfer point, HS-SICH and HS-PDSCH be the subframe in interval always, that is, if received the HS-PDSCH transmission that is sent to oneself in subframe n, UE is sending feedback information on the HS-SICH in association after the subframe in interval.Because a HS-PDSCH sends and points to a UE, guaranteed that equally also HS-SICH of synchronization only can be used by a UE.
When the HS-SICH channel that uses under the HS-SCCH-less pattern is shared by the UE in the common HS-DSCH transmission mode, promptly, when the HS-SICH of the HS-SCCH of part UE configuration and HS-SICH channel centering and HS-SICH channel sharing that another part UE uses under the HS-SCCH-less pattern, need Node B to guarantee that the HS-SICH channel can not clash in the sub-district.Because the timing relationship nHS-SCCH between HS-SCCH and the HS-PDSCH also is (nHS-SCCH 〉=3 time slot) determined, Node B can avoid HS-SICH channel of synchronization to be used by more than one UE when dispatching fully.
In the present embodiment, how to select HS-SICH channel, simple possible by carrying out HS-SICH and HS-PDSCH channel related, clear and definite UE; Utilize simultaneously in the HS-DSCH of the TD-SCDMA system transmission, the timing relationship that HS-SCCH, HS-PDSCH and HS-SICH interchannel are determined makes these resources still be shared with time division way by the UE in the sub-district as shared resource and uses, and can not cause conflict.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
