Description
Technical field
The present invention relates to wireless communication technology field, more specifically, relate to a kind of decoding device of reinforced uplink physical channel of time-division synchronous code division multiple access system.
Background technology
In March, 2006, third generation partner program (3rd Generation PartnershipProject is designated hereinafter simply as 3GPP) has been passed through the project verification application of TD SDMA (TD-SCDMA) system enhanced uplink.Enhanced uplink is commonly referred to as high speed uplink packet and inserts (High Speed Uplink Packet Access is designated hereinafter simply as HSUPA), and purpose is that the technology by the advanced person improves the efficient of up link.
Increased a transmission channel among the HSUPA newly, that is, enhanced uplink dedicated transmission channel (E-DCH) strengthens uplink business data and is carried on this transmission channel, and the Transmission Time Interval of E-DCH (TTI) is 5ms.In a TTI, form the coded combination transmission channel by an E-DCH transmission channel, be carried on the E-PUCH (the E-DCH uplink physical channel is also referred to as the enhancing uplink physical channel).
The HSUPA technology mainly contains following feature:
(1) dispatch the base station: before adopting the HSUPA technology, the uplink scheduling function realizes in service wireless network controller (SRNC), in the HSUPA technology scheduling feature is transferred to the base station, can use the information on load of sub-district more accurate and in real time, thereby utilize the ascending idle port resource more fully.Business based on base station scheduling is called dispatching services, subscriber equipment (UE) is before the transmission data, insert ascending control channel (E-RUCCH) at random by E-DCH earlier and send dispatch request, then, the base station is the UE Resources allocation according to the dispatch request of UE and the resource situation of sub-district, and by E-DCH absolute grant channel (E-AGCH) resource (comprising code channel, time slot and power) of authorizing is sent to UE.
(2) mix re-transmission (HARQ) automatically: before adopting HSUPA, the re-transmission of upstream data need be carried out at the rlc layer of SRNC, in the HSUPA technology functions of retransmission is transferred to the base station, has shortened retransmitting the required time.Receive the E-PUCH channel data of UE when the base station after, the physical layer of base station is decoded, and decoded information is fed back to the upper strata strengthen medium access control entity (MAC-e), by the MAC-e entity be responsible for producing " affirmation " (ACK) or " not confirming " (NACK) indicate, and on E-DCH hybrid automatic repeat request indication channel (E-HICH), indication is sent to UE, after UE receives ACK, will abandon original grouping, carry out the transmission of new data; If that receive is NACK, need then to wait for that authorization resources retransmits again.
In order to adapt to the stronger business of real-time, HSUPA also provides non-scheduling service, and its resource is that UE distributes by SRNC, and the method for salary distribution is the same with existing dedicated channel allocation mode.A UE can have dispatching services and non-scheduling service simultaneously, when an E-DCHTTI arrives, oneself determines transmission dispatching services data or non-scheduling service data by UE is high-rise.Therefore, when the existing scheduling resource of UE, when again non-scheduling resource being arranged simultaneously, will there be the waste of resource.TD-SCDMA allows UE to integrate scheduling resource and non-scheduling resource, such as working as UE existing scheduling resource in current TTI, when again non-scheduling resource being arranged simultaneously, UE can determine current scheduling and non-scheduled resources sum total are used for the transmission of non-scheduling service data or the transmission of dispatching services data, hereinafter, it is abbreviated as " resource multiplex ".
In the uplink strengthening data transmission course, UE need be to some control informations of base station transmits to help base station decodes E-PUCH, these information-bearings are on a physical layer control channel-enhancing ascending control channel (E-UCCH), the information that comprises as shown in Figure 1, wherein strengthening transformat combination indication (E-TFCI) is an index value, the transport block length and the modulation system of this transmission of UE have been indicated, the number of resources of it and E-PUCH is relevant, and the modulation system that obtains transport block length and E-PUCH channel is translated according to the number of resources that UE uses in the base station from E-TFCI; RSN is a retransmission counter, also implicit HARQ redundancy version information; The HARQ process ID is used to indicate handles the process number that HARQ retransmits, and also comprises the traffic data type (scheduling or non-scheduling) of this transmission simultaneously.The base station uses these information on the E-UCCH to come E-PUCH is carried out physical layer decoding and HARQ processing.E-UCCH transmits by the E-PUCH channel; the frame structure of the protected level of E-UCCH and E-PUCH is not also determined at present; but what can determine is; E-UCCH will be by E-PUCH physical channel indication territory transmission; and employing fixing, known modulation and coded system; because the demodulation sign indicating number only behind correct demodulation sign indicating number E-UCCH, could be carried out to E-PUCH channel service data division in the base station.
Fig. 2 is the schematic diagram of E-PUCH channel architecture.As shown in Figure 2, the E-PUCH channel comprises: two business datum parts; Two physical channel indication territories; An intermediate code part; And boundary belt.E-UCCH is mapped in the physical channel indication territory and transmits.
Because allow in the solution of TD-SCDMA HSUPA that UE dispatches, non-scheduling resource multiplexing, but do not force that UE dispatches, non-scheduling resource multiplexing, again because E-TFCI value relevant with number of resources (identical E-TFCI value corresponding transport block length under different number of resources situations is different with modulation system), thereby in a TTI, the base station must all be detected scheduling, the non-scheduling resource of distributing to this UE, could determine the definite implication of E-TFCI value, could carry out the demodulation sign indicating number to the E-PUCH channel then.Be distributed in the time slot 1 such as scheduling resource, non-scheduling resource is distributed in the time slot 2, base station and what do not know UE transmission is data dispatching, it also is non-data dispatching, do not know whether UE has carried out the multiplexing of resource yet, thereby when a TTI arrives, the base station need be detected this UE and whether send data in time slot 1, no matter detect still detect less than, also need in time slot 2, detect this UE and whether send data, by the time after finishing all resource detections, modulation system and the transport block length that this E-PUCH uses could be determined in the base station.
Therefore, in the prior art, because allow that UE dispatches, non-scheduling resource multiplexing, this UE must have been detected after all resources of this TTI in the base station, just can obtain the modulation system of this TTI E-PUCH channel service data division and the information of transport block length, and then carry out the demodulation sign indicating number.Obviously, so just cause the buffer memory of the preceding channel data of demodulation and the time delay of Channel Processing, thereby reduced the receiving efficiency of E-PUCH channel.
