Description
Technical field
The present invention relates to the communications field, in particular to a kind of multicarrier semi-persistent scheduling method and system.
Background technology
3G (Third Generation) Moblie Long Term Evolution (Long Term Evolution, abbreviate LTE as) wave point medium access control (the Media Access Control of " universal land radio access web of evolution (the Evolved Universal Terrestrial Radio AccessNetwork; abbreviate E-UTRAN as; form; therefore also can be called base station eNB) " of system by base station eNB, abbreviate MAC as) protocol layer, there is scheduling/processed (Scheduling/Priority handling) functional entity, wherein, scheduling feature is supported dynamic dispatching (Dynamic scheduling) and semi-persistent scheduling (or being called semi-persistent scheduling) (Semi-persistent Scheduling).
Dynamic dispatching (Dynamic Scheduling) is meant, E-UTRAN can pass through Physical Downlink Control Channel (Physical Downlink Control Channel, abbreviate PDCCH as) on Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (Cell Radio Network Temporary Identifier, abbreviate C-RNTI as) at each Transmission Time Interval (Transmit Time Interval, abbreviate TTI as, corresponding to a subframe (subframe)) be used for UE reception/transmission data to subscriber equipment (UE) dynamic assignment resource, resource comprises Physical Resource Block (Physical Resource Block, abbreviate PRB as) and Modulation and Coding Scheme (Modulation and Coding Scheme abbreviates MCS as) etc.UE mixes the head biography and the HARQ re-transmission of automatic repeat requests (Hybrid ARQ abbreviates HARQ as) all can use dynamic dispatching.
Semi-persistent scheduling (Semi-persistent Scheduling:SPS) is meant, E-UTRAN can be used for UE reception/transmission data for UE distributes semipersistent resource by the semi-persistent scheduling Cell Radio Network Temporary Identifier/Identity, Cell-RNTI on PDCCH (Semi-PersistentScheduling C-RNTI:SPS C-RNTI), and resource comprises Physical Resource Block PRB, Modulation and Coding Scheme MCS etc.In semi-persistent scheduling, the first biography of the HARQ of UE used semipersistent resource, and HARQ retransmits the resource of using dynamic dispatching.Semipersistent resource repeated to take place according to the cycle of being disposed, and the subframe (Subframe) in that UE is configured with semipersistent resource if UE does not monitor its C-RNTI on PDCCH, then receives/sends according to semipersistent resource in corresponding subframe.Be configured with the subframe of semipersistent resource at UE,, then use the dynamic resource of PDCCH indication to substitute (Override) semipersistent resource in corresponding subframe if UE monitors its C-RNTI on PDCCH.
Typically, semi-persistent scheduling is applied to the VoIP business, for the semipersistent resource of its distribution is the cycle with 20ms.E-UTRAN is by Radio Resource control (Radio Resource Control, abbreviating RRC as) signaling is UE configuration semi-persistent scheduling parameter, comprises semi-persistent scheduling sub-district-Radio Network Temporary Identifier, the configuration of descending semi-persistent scheduling, up semi-persistent scheduling configuration etc.Descending/up semi-persistent scheduling parameter can dispose respectively, and descending semi-persistent scheduling parameter comprises information such as the HARQ process number, PUCCH feedback resources of descending semi-persistent scheduling cycle, reservation; Up semi-persistent scheduling parameter comprises information such as up semi-persistent scheduling cycle, implicit expression dropout value, PUSCH relevant parameter, also comprises two cycle configuration informations for tdd mode.E-UTRAN by the RRC signaling enable/go to enable (enable/disable) descending/up semi-persistent scheduling, when descending/when up semi-persistent scheduling went to enable, corresponding semipersistent resource was released.LTE frequency division multiplex pattern (Frequency Divided Duplex:FDD) is at descending/up one-period of supporting at most respectively.Time division multiplexing pattern (Time Divided Duplex:TDD) is at the descending one-period of only supporting, up two cycles of support be configured to avoid HARQ to retransmit and the conflict of semipersistent resource during the first biography of HARQ.Descending, E-UTRAN is the HARQ process number that UE configuration semi-persistent scheduling is reserved by RRC, and dynamic dispatching can be shared the HARQ process of keeping for semi-persistent scheduling.Up, dynamic dispatching and semi-persistent scheduling also can be shared same HARQ process.E-UTRAN is that UE activates semipersistent resource by PDCCH.In order to reduce the complexity of semi-persistent scheduling, semipersistent resource is distributed to whole UE, rather than distributes to certain concrete business.Descending/up maximum difference only dispose a semipersistent resource (comprising information such as PRB, MCS), and this semipersistent resource took place according to descending/up semi-persistent scheduling cycle that the RRC signaling is disposed.E-UTRAN is by descending/up semipersistent resource of the explicit release of PDCCH UE.Up, also support implicit expression to discharge semipersistent resource, UE triggers semipersistent resource according to several continuous new MAC PDU (media access control protocol data unit) that comprise 0 MAC SDU (medium access control Service Data Unit) and discharges.
In order to satisfy the demand that growing big bandwidth high-speed mobile inserts, third generation partnership project (Third Generation Partnership Projects, abbreviation 3GPP) releases senior Long Term Evolution (Long-Term Evolution advance is called for short LTE-Advanced) standard.LTE-Advanced adopts series of new techniques that frequency domain, spatial domain are expanded on the LTE basis, to reach purposes such as improving the availability of frequency spectrum, increase power system capacity.Wherein carrier aggregation technology can the two or more component carriers of polymerization (Component Carrier) to support wideer frequency band, for example, arrive 100MHz and spectrum aggregating.UE is reception/transmission data on one or more component carriers simultaneously, can be configured in descending/different numbers of up gathering and have the component carrier of different bandwidth.Corresponding HARQ entity of each component carrier and transmission channel.There is being an independent PDCCH to indicate resource allocation on the well-behaved loading gage ripple or the resource allocation on other component carrier on each component carrier respectively, 0～3bit indication component carrier identification information is being arranged on the PDCCH.
In the LTE system, if have a plurality of business to be fit to semi-persistent scheduling descending and/or up, then need to take all factors into consideration service quality (the Quality of Service:QoS) requirement of different business, at the descending and/or up recurrent semipersistent resource of 1 group of unified semi-persistent scheduling parameter and 1 unification that disposes respectively at most.Cause the dumb or waste of radio resources of semi-persistent scheduling to a certain extent, have to sometimes utilize dynamic dispatching to compensate, waste PDCCH resource.In LTE-Advanced system carrier aggregation technology, also there is not the solution of semi-persistent scheduling at present.
