Description
Technical field
The present invention relates to the communications field, in particular to a kind of instruction of resource scheduling information, distribution method and device.
Background technology
The fast development of mobile Internet, Internet of Things and other service application has become the main drive that promotion the 5th third-generation mobile communication technology (5G) develops.They an urgent demand 5G has the access rate of the optical fiber that matches in excellence or beauty, the concatenation ability of hundred billion equipment, perfectly real-time experience and wireless broadband Internet access ability anywhere or anytime.In addition, the important indicator such as energy consumption efficiency, spectrum efficiency and peak rate also needs to be considered when 5G system.China has set up the development that IMT-2020 (5G) propelling group advances 5G technology in 2013.According to international overall condition, estimate within 2015, to form the planning of 5G vision, critical capability demand and frequency spectrum, 5G standardization effort will be started afterwards, and start commercial after the year two thousand twenty.In international standard, the technical standard that Long Term Evolution strengthens (LTE-Advanced) is mainly worked out in third generation partner program (3GPP) International Organization for standardization.Industry is tentatively thought in the research on standard work that the 3GPPR14 stage (being estimated in 2016) will start towards 5G.
In the mobile network in future, traffic needs can improve constantly, terminal number and kind are also constantly obvious in the demand differenceization such as explosive growth, QoS of customer (QOS), and these all need the solution for different scene research correspondence.As one of the important scenes of 5G, the target of mobile relay network is that the user that can be in common mobile status for a group provides better broadband access ability.This one of them typical application scenarios is exactly provide better access service by disposing mobile relay node for passenger on the vehicles (such as: bus, passenger vehicle, train, steamer etc.) that user density is higher.In such a scenario, mobile relay technology has many advantages.On the one hand, passenger can increase single user throughput by utilizing return link good between via node and base station.If adopt traditional base station access way, the channel quality of the direct-connected access link between passenger and base station can be subject to the impact of the surrounding environment of constantly change; Further, the penetration loss of the vehicles and kinetic Doppler effect all can make channel quality worsen further.Such as: the penetration loss of the vehicle of actual measurement is generally between 3.2 to 23.8dB.By introducing via node, the antenna being deployed in vehicle exterior can be utilized to the penetration loss avoiding the vehicles to bring.In addition, via node itself by being equipped with the better transceiver of performance, and can also carry out the performance that more complicated data processing (such as: the compensation of Doppler effect) promotes return link further.In this case, even if mobile relay node needs extra resource to carry out with passenger the information interaction of the second jumping, the single user throughput of passenger and the spectrum efficiency of entirety still can be greatly improved.In addition, base station by increasing the overall throughput of whole community at the larger multiplexing identical Radio Resource in different relay services regions of distance, thus can also obtain resource multiplex gain.
But, in mobile relay network, due to the mobility of via node, the macrocell that mobile relay service area is generally always served with base station is overlapping, therefore when the Radio Resource of the macrocell that relay services district sharing base is served, return link between mobile relay node and base station, the relaying access link between mobile relay node and passenger and the interference between the direct-connected access link between other direct-connected user and base station must take in.In such cases, if adopt nontransparent trunking scheme (namely via node is equivalent to a little base station), between relaying access link and direct-connected access link, interference must be evaded by adopting different subframes.Other resource division mode granularity of this sub-frame level is very large, and the configuration of the access-in resource of via node cannot carry out real-time change with traffic carrying capacity, is easy to thus bring the larger wasting of resources.In addition, base station this as supporting that legacy user must access at relaying the transmission that subframe still keeps public reference signal, this causes interference by sending the data of via node.So the technical scheme that the embodiment of the present invention provides pays close attention to the solution under transparent trunking scheme more.
Under transparent trunking scheme, user remains on a control plane and carries out interconnective with base station, obtains resource scheduling information from base station, and receives from the data of via node transmission under the control of base station or send data to via node.Because passenger moves together at vehicle interior and along with via node, although surrounding enviroment constantly change, the relaying access link between passenger and via node but can keep good performance always.And because the distance between via node and passenger is less, relaying access link can adopt the modulation coding mode of high-order, such as: 64QAM, even 256QAM.So for passenger, the performance of relaying access link will be far superior to the direct-connected access link between itself and base station.
But in transparent trunking scheme, user still needs to obtain resource scheduling information from base station, namely obtained by the control channel unit (CCE) in the Physical Downlink Control Channel (PDCCH) on the direct-connected access link of decoding.In LTE system, base station adopts QPDK to be adjusted regularly in PDCCH, and defines different polymerization grade (1,2,4,8) and guarantee its correct reception under different channels condition.Polymerization grade 1 can be adopted, by Downlink Control Information (DCI) unit maps in a CCE when channel condition is better.Then can adopt polymerization grade 8 when channel condition is poor, by a DCI unit maps in 8 CCE, thus greatly reduce the effective code check of DCI in transmitting procedure.So the open defect existed in transparent trunking scheme is: because passenger still needs the direct-connected access link Gains resources schedule information by poor-performing, and relevant signaling consumption is very large.Particularly when there being a lot of passenger to need to carry out broadband access in the vehicles, this defect will be more outstanding.For a way-train, general passengers quantity can reach 50 ~ 100.Along with the develop rapidly of polytype business, the passenger's various broadband services of access during by bus having significant proportion can be predicted.As can be seen here, the signaling consumption how reducing wireless resource scheduling in transparent trunking scheme is a key issue urgently to be resolved hurrily.
