Description
Technical field
The present invention relates to the communications field, and especially, relate to a kind of collocation method and base station of wireless resource scheduling.
Background technology
At 3G (Third Generation) Moblie Long Term Evolution (Long Term Evolution, abbreviate LTE as) in the system, the universal land radio access web of evolution (Evolved UniversalTerrestrial Radio Access Network, abbreviate E-UTRAN as) by base station (eNodeB, abbreviate eNB as) form, so E-UTRAN also can be called the base station.Wherein, Radio interface protocols uplink layer 2 structures of E-UTRAN as shown in Figure 1, comprise packet data convergence protocol, radio link control layer, medium access control (MediaAccess Control, abbreviate MAC as) protocol layer, wherein, at the MAC 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: abbreviate SPS as); The processed function is supported the processed of the Different Logic interchannel of same subscriber equipment (User Equipment abbreviates UE as), also supports to carry out processed between the different UEs by dynamic dispatching.
Wherein, up dynamic dispatching function is meant: up, E-UTRAN can be by sub-district-Radio Network Temporary Identifier (the Cell RadioNetwork Temporary Identifier on 1/ layer of 2 (L1/L2) control channel of layer, abbreviate C-RNTI as) at each Transmission Time Interval (Transmit Time Interval, abbreviate TTI as, corresponding to a subframe (subframe)) be the UE Resources allocation, for example, Physical Resource Block (Physical Resource Block, abbreviate PRB as) and Modulation and Coding Scheme (Modulation and Coding Scheme abbreviates MCS as).And, allowing to carry out under the situation of descending reception (being controlled) by discontinuous reception functionality, UE is 1/ layer of 2 control channel of monitor layer always, thereby be the possible resource allocation of up discovery.Wherein, 1/ layer of 2 control channel of layer is meant Physical Downlink Control Channel (Physical Downlink Control Channel, abbreviate PDCCH as), this channel is when being used for uplink scheduling, mainly be to carry uplink scheduling authorization (UL Grant), mainly comprise Resource Block (Resource Block, abbreviate RB as) assignment information, Modulation and Coding Scheme, mix automatic repeat requests (Hybrid Automatic Repeat Request, abbreviate HARQ as) information, transmission power control (Transmit Power Control, abbreviate TPC as) information, Radio Network Temporary Identifier/cyclic redundancy check (CRC) information such as (Cyclic Redundancy Check abbreviate CRC as).When uplink scheduling, UE is by Physical Uplink Control Channel (Physical Uplink Control Channel, abbreviate PUCCH as) carry dispatch request and channel quality indication (Channel Quality Indicator, abbreviate CQI as), the capable physically shared channel (Physical Uplink Shared Channel abbreviates PUSCH as) of upstream data is gone up and is sent.Dispatch request also can send by Random Access Channel, and CQI also can send by PUSCH.E-UTRAN is by the affirmation/non-affirmation response message (ACK/NACK) of the automatic repeat requests indicating channel of physical mixed (Physical Hybrid ARQ Indicator Channel abbreviates PHICH as) to the up transmission feedback HARQ of UE.
Up semi-persistent scheduling is meant: E-UTRAN can send for the HARQ first of UE and distribute predefined ascending resource, for example opportunity (Timing), resource, transformat (Transport Format) parameter etc.During UE was by the subframe of pre-allocation resource (Subframe), if UE does not find its C-RNTI on the L1/L2 control channel, then UE carried out up transmission at corresponding TTI according to the predefine resource.Network based predefined Modulation and Coding Scheme is decoded to predefined Physical Resource Block.In addition, during UE is by the subframe of pre-allocation resource, if UE has found its C-RNTI on the L1/L2 control channel, then UE carries out up transmission at corresponding TTI according to the indicated information of L1/L2 control channel, that is to say that the distribution of L1/L2 control channel substitutes the predefine of (Override) corresponding TTI and distributes, promptly, at corresponding TTI, dynamic dispatching may cover semi-persistent scheduling.
At present, in correlation technique, generally speaking, HARQ retransmits and uses the dynamic dispatching mode, also may use the semi-persistent scheduling mode.Typically, semi-persistent scheduling is applied to ip voice (Voice over Internet Protocol abbreviates VoIP as) business.Semi-persistent scheduling carries out initial configuration by Radio Resource control (Radio Resource Control abbreviates RRC as) signaling, for example, distributes the cycle (Periodicity) of semi-persistent scheduling.The activation of semi-persistent scheduling (Activation) is controlled by PDCCH, it is semi-durable or dynamic that PDCCH indicates uplink authorization (UL Grant) by certain mechanism, for example, PDCCH indicates by SPS C-RNTI, this SPS C-RNTI during with dynamic dispatching employed C-RNTI different.After UE has been assigned with predefined semipersistent resource, generally do not need to send dispatch request by PUCCH again.HARQ for dynamic dispatching or semi-persistent scheduling retransmits, and all can use self adaptation to retransmit mode or non-self-adapting re-transmission mode.Wherein, self adaptation retransmits and refers to that HARQ retransmits the re-transmission of carrying out according to information such as the indicated resource of the last control of PDCCH signaling, MCS; Non-self-adapting retransmits and refers to that HARQ retransmits the last HARQ of basis and sends the re-transmission that information such as (can pass for HARQ is first or the HARQ re-transmission) employed resource, MCS are carried out, and, sends information such as using identical resource, MCS with last HARQ that is.Non-self-adapting retransmits and can only trigger according to the NACK feedback, for example, retransmits for ascending HARQ, if UE detects NACK and do not monitor PDCCH on PHICH, then can carry out non-self-adapting and retransmit.
At cell edge,, therefore in a TTI, possibly can't finish the transmission of whole VoIP packet because uplink budget is low.Like this, can carry out segmentation to the VoIP packet by control (Radio Link Control abbreviates RLC as) layer at Radio Link, and in a plurality of TTI, send these segmentations respectively.But above-mentioned processing will increase the header overhead of layer 2, and this is because the transmission of each segmentation all need send uplink authorization (Grant) on PDCCH, therefore can increase the consumption of PDCCH resource.Each first biography or re-transmission all need be at the automatic repeat requests indicating channel of physical mixed (Physical Hybrid ARQIndicator Channel, abbreviate PHICH as) on carry out acknowledge message/non-acknowledge message (ACK/NACK) feedback, thereby increased wrong probability.
For solving the above problems, can use transmission time interval (tti) bundle (TTI bundling) scheme to solve the limited problem of up covering in the long evolving system.Be that example describes with the ip voice business below.Up TTI bunching scheme allows to use one group of continuous transmission block (Transport Block of subframe transmission, abbreviate TB as) different redundancy versions (Redundancy Version, abbreviate RV as), the feedback that before the HARQ of TTI boundling inside re-transmission does not need to wait for, once sends.Single TTI boundling uses same HARQ process, only needs single uplink authorization and single feedback, and other subframe in the TTI boundling except that first subframe all uses non-self-adapting to retransmit.The TTI bunching scheme can carry out On/Off at UE by high-level signaling, and after unlatching, relevant upstream data sends and will use the TTI bunching scheme.The number of the employed continuous subframes of TTI boundling can be fixed, or is configured with open command by the RRC signaling.Use Loop Round Trip Time (the Round Trip Time of TTI bunching scheme to HARQ, abbreviate RTT as), the timing relationship that retransmits of HARQ feedback and HARQ can bring certain influence, at present, third generation partner plans (3rdGeneration Partnership Project, abbreviating 3GPP as) scheme taked is that the opportunity of the ACK/NACK feedback of TTI boundling is based on the position of last subframe of TTI boundling.
Such scheme is applicable to Frequency Division Duplexing (FDD) (Frequency divided duplex abbreviates FDD as) and two kinds of patterns of time division duplex (Time divided duplex abbreviates TDD as).For fdd mode, the ACK/NACK feedback of TTI boundling is positioned at the 4th subframe (Last Bundled Subframe+4) after last subframe of TTI boundling opportunity, and the retransmission operation of TTI boundling occurs in after first subframe of TTI boundling the subframe of 2 times HARQ RTT position.
Wherein, the principle schematic of TTI bunching scheme as shown in Figure 2 under the fdd mode, 3GPP has adopted the TTI boundling size of 4 fixing continuous subframes, HARQ process 0 uses these 4 continuous TTI to send redundancy versions 0～3 (RV=0 of transmission block, RV=2, RV=3, RV=1), the ACK/NACK feedback of TTI boundling is in the position of HARQ process 7 virgin's frames, and the re-transmission of TTI boundling is in the position of 2 HARQ RTT.The HARQ of TTI boundling feedback is relevant with concrete HARQ process configuration relation with the timing relationship that HARQ retransmits under the tdd mode, but basic principle and fdd mode are similar, that is, its HARQ feedback also is based on last subframe of TTI boundling.
In correlation technique, use the TTI bunching scheme and use the semi-persistent scheduling scheme all can reduce the expense of PDCCH to a great extent, although being used in combination, both can also further reduce the PDCCH expense, but the gain that brings is limited, and increased the complexity that system realizes, wherein, can increase bigger complexity for tdd mode, less relatively for the complexity that fdd mode increases.
Whether current 3GPP is discussing needs the scheme of using TTI boundling and SPS to combine, and have two kinds of viewpoints: the first should support TTI boundling and SPS to use simultaneously; It two is not support TTI boundling and SPS to use simultaneously, but does not reach an agreement as yet.Proposing as yet at present can flexible configuration TTI boundling and the technical scheme of the occupation mode (using simultaneously simultaneously or not) of SPS.
