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, referred to as LTE) " universal land radio access web (the Evolved Universal Terrestrial Radio AccessNetwork of evolution of system, referred to as E-UTRAN, be made up of base station eNB, therefore also can be called base station eNB) " wave point medium education (Media Access Control, referred to as MAC) protocol layer, there is scheduling/processed (Scheduling/Priority handling) functional entity, wherein, scheduling feature supports dynamic dispatching (Dynamic scheduling) and semi-persistent scheduling (or being called semi-persistent scheduling) (Semi-persistent Scheduling).
Dynamic dispatching (Dynamic Scheduling) refers to, E-UTRAN can pass through Physical Downlink Control Channel (Physical Downlink Control Channel, referred to as PDCCH) on Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (Cell Radio Network Temporary Identifier, referred to as C-RNTI) at each Transmission Time Interval (Transmit Time Interval, referred to as TTI, corresponding to a subframe (subframe)) receive/send data to subscriber equipment (UE) dynamic allocation of resources for UE, resource comprises Physical Resource Block (Physical Resource Block, referred to as PRB) and Modulation and Coding Scheme (Modulation and Coding Scheme, referred to as MCS) etc.The head of UE hybrid automatic repeat-request (Hybrid ARQ, referred to as HARQ) passes and HARQ re-transmission all can use dynamic dispatching.
Semi-persistent scheduling (Semi-persistent Scheduling:SPS) refers to, E-UTRAN can receive/send data for UE distributes semipersistent resource for UE by the semi-persistent scheduling Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (Semi-PersistentScheduling C-RNTI:SPS C-RNTI) on PDCCH, and resource comprises Physical Resource Block PRB, Modulation and Coding Scheme MCS etc.In semi-persistent scheduling, the HARQ head of UE passes and uses semipersistent resource, and HARQ retransmits the resource using dynamic dispatching.Semipersistent resource repeated to occur according to the configured cycle, the subframe (Subframe) of semipersistent resource is configured with at UE, if UE does not monitor its C-RNTI on PDCCH, then carry out receiving/sending according to semipersistent resource in corresponding subframe.Be configured with the subframe of semipersistent resource at UE, if UE monitors its C-RNTI on PDCCH, then use the dynamic resource of PDCCH instruction to substitute (Override) semipersistent resource in corresponding subframe.
Typically, semi-persistent scheduling is applied to VoIP business, and the semipersistent resource distributed for it is the cycle with 20ms.E-UTRAN is by wireless heterogeneous networks (Radio Resource Control, referred to as RRC) signaling is that UE configures semi-persistent scheduling parameter, comprises semi-persistent scheduling community-Radio Network Temporary Identifier, the configuration of descending semi-persistent scheduling, up semi-persistent scheduling configuration etc.Descending/up semi-persistent scheduling parameter can configure respectively, and descending semi-persistent scheduling parameter comprises descending semi-persistent scheduling cycle, the reserved information such as HARQ process number, PUCCH feedback resource; Up semi-persistent scheduling parameter comprises the information such as up semi-persistent scheduling cycle, implicit expression dropout value, PUSCH relevant parameter, also comprises two period assignment information for tdd mode.E-UTRAN by RRC signaling enable/remove enable (enable/disable) descending/up semi-persistent scheduling, when descending/up semi-persistent scheduling goes enable, corresponding semipersistent resource is released.LTE frequency division multiplex pattern (Frequency Divided Duplex:FDD) supports one-period at most respectively descending/up.Time division duplex mode (Time Divided Duplex:TDD) only supports one-period descending, up two cycles of support be configured to avoid HARQ to retransmit and HARQ first biography time semipersistent resource conflict.Descending, E-UTRAN by RRC be UE configure semi-persistent scheduling the HARQ process number reserved, dynamic dispatching can share the HARQ process keeping for semi-persistent scheduling.Up, dynamic dispatching and semi-persistent scheduling also can share 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 distributes to whole UE, instead of distributes to certain concrete business.Descending/up maximum difference only configures a semipersistent resource (comprising the information such as PRB, MCS), and descending/up semi-persistent scheduling cycle that this semipersistent resource configures according to RRC signaling occurs.E-UTRAN is by descending/up semipersistent resource of PDCCH explicit release UE.Up, also support implicit expression release semipersistent resource, UE triggers semipersistent resource release according to the new MAC PDU (media access control protocol data unit) that several continuous print comprise 0 MAC SDU (medium education Service Data Unit).
In order to meet the demand of growing large bandwidth high-speed mobile access, third generation partnership project (Third Generation Partnership Projects, be called for short 3GPP) release senior Long Term Evolution (Long-Term Evolution advance is called for short LTE-Advanced) standard.LTE-Advanced adopts series of new techniques to expand frequency domain, spatial domain on LTE basis, improves the availability of frequency spectrum, increases the objects such as power system capacity to reach.Wherein carrier aggregation technology can be polymerized two or more component carrier (Component Carrier) to support wider frequency band, such as, arrives 100MHz and spectrum aggregating.UE can receive simultaneously/send data on one or more component carriers, can be configured in the component carrier that the different number of descending/up gathering has different bandwidth.The corresponding HARQ entity of each component carrier and transmission channel.Each component carrier there is respectively an independent PDCCH indicate the Resourse Distribute on this component carrier or the Resourse Distribute on other component carrier, PDCCH has 0 ~ 3bit indicate component carrier identification information.
In LTE system, if have multiple business to be applicable to semi-persistent scheduling descending and/or up, then need service quality (the Quality of Service:QoS) requirement considering different business, at the descending and/or up recurrent semipersistent resource configuring at most 1 group of unified semi-persistent scheduling parameter and 1 unification respectively.Cause the dumb or waste of radio resources of semi-persistent scheduling to a certain extent, sometimes have to utilize dynamic dispatching to compensate, waste PDCCH resource.In LTE-Advanced system carrier aggregation technology, also there is no the solution of semi-persistent scheduling at present.
