Background technology
Along with the development of network architecture flattening and the appearance of the removable access way of multiple high-speed wideband, make the transmission rate that the wireless communication system of evolution can provide higher, shorter transmission delay, lower cost, support 3GPP (The 3rd Generation Partnership Project simultaneously, 3G (Third Generation) Moblie partnership project) mobility between inter Access System, and mobility between 3GPP connecting system and non-3 GPP access system etc., mobile communications network is impelled to propose LTE (LongTime Evolution, mobile communication system Long Term Evolution)/SAE (System ArchitectureEvolution, System Architecture Evolution) framework theory of future generation.
In LTE system, allocation of radio resources mechanism has the feature different from traditional approach.In traditional 3G equipment, Radio Resource is distributed by RNC, causes traffic resource assignment can not adapt channel, and protocol architecture is too complicated, is unfavorable for system optimization.And the flattening design of LTE, the function relevant to air interface is made all to be concentrated in enode b (evolution Node B, hereinafter referred to as eNB), wireless spread-spectrum technology (Radio Link Control, hereinafter referred to as RLC) and media interviews control (MediumAccess Control, hereinafter referred to as MAC) be all in same network node, therefore scheduler can carry out dynamic dispatching according to channel quality to data, thus reduce filling, make full use of the transmittability of channel, then improve the availability of frequency spectrum.And for some business, its data characteristic is periodically strong, (as network telephone service (Voice over IP, hereinafter referred to as VOIP), his data characteristics is wrap smaller, regular, cycle is short) like this in order to reduce the expense of control channel, LTE proposes semi-persistent scheduling, and the one as dynamic dispatching is supplemented.
Semi-persistence Scheduling (SPS, lower semi-persistent scheduling) refer to design for specific transactions, need activation/releasing resource, to use at fixed time and allocate resource in advance and carry out a kind of dispatching method of dynamic dispatching (re-transmission) in other moment.In order to avoid system complexity, all business of UE, signaling can use SPS resource, be not specially for the business (as VOIP) of periodic scheduling, and the business of periodic scheduling, when there is no SPS resource, the resource of dynamic dispatching also can be used.So rational activation/reactivation SPS, can ensure that system bandwidth makes full use of.The flow process relevant with SPS has several as follows:
1.SPS parameter configuration:
SPS parameter is by rrc layer in RRC connection establishment, RRC connection re-establishment, or is set to UE's in RRC connection reprovision.Parameter of (see Figure of description 1,2,3) main configuration is that SPS is enable or forbid.SPS parameter is configured when SPS is enable, as the cycle of SPS C-RNTI, SPS, SPS Processes sum etc.
2.SPS activation/reactivation:
In the enable situation of SPS, and when having SPS data, eNB is activated by special PDCCHOrder (Physical Downlink Control Channel, Physical Downlink Control Channel).The distribution of static resource (comprising RB (resource block) quantity, RB position, MCS (Modulation and CodingScheme) etc.) is included in PDCCH activation command.Activating the moment of coming into force is exactly the moment of launching PDCCH activation command.After SPS activates, eNB can also carry out SPS reactivation according to the data cases of channel quality or transmission.Uplink activation and lower line activating are independent judgments.
3.SPS deexcitation:
Be divided into display and implicit expression deexcitation two kinds of modes, the former carrys out deexcitation by special PDCCH Order (PDCCH order).The latter is only come into force to up.Refer to that UE is by transmission 2,3,4 or 8 zero mac sdu (empty MAC message, is the BSR of 0) carry out deexcitation continuously.After deexcitation, the SPS resource of eNB and UE all discharges.
BSR (buffer state report, buffer status reporting) refers to that UE needs a report of the up data buffer sent, and is divided into long BSR and short BSR (see Figure of description 4,5).UE reporting uplink buffer area data volume is that logically channel group (Logic Channel Group, is called for short LCG later) reports.LCG mono-has 4, is respectively 0,1,2,3 according to height prioritization.
