Description
Technical field
The present invention, about a kind of method for a wireless telecommunication system and communication device thereof, espespecially is a kind ofly used for strengthening the method for sounding reference signal transmission enhancement and communication device thereof for a wireless telecommunication system.
Background technology
Third generation partner program (the3rdGenerationPartnershipProject, Long Term Evolution (LongTermEvolution 3GPP) formulated, LTE) system, is regarded as the new wave point of one that provides high data transmission rate, low latent time, package optimization and improve power system capacity and coverage and wireless network architecture.In long evolving system, evolved general land global radio access network (EvolvedUniversalTerrestrialRadioAccessNetwork, E-UTRAN) multiple evolved base station (evolvedNode-B is comprised, eNB), its on the one hand in order to client (userequipment, UE) communication is carried out, on the other hand in order to process Non-Access Stratum (NonAccessStratum, NAS) core network controlled carries out communication, and core network comprises servo gateway (servinggateway) and mobile management unit (MobilityManagementEntity, the device such as MME).
In long evolving system, the detection reference signal (soundingreferencesignal, SRS) that client transmits received by evolved base station.Detection reference signal is mainly used in channel quality estimation, to perform frequency selective scheduling (frequency-selectivescheduling) in uplink between different clients, therefore client can be greater than the frequency band transmitting data and control signal and use for the frequency band transmitting detection reference signal.In addition, the frequency band that client is used for transmitting detection reference signal can overlap mutually, on the frequency band that evolved base station can be overlapped in these, between client, performs frequency selective scheduling.Further, frequency selective scheduling can be used for strengthening power and controls, modulates and coding method (modulationandcodingscheme, MCS) select, locate and shift to an earlier date sequential (timingadvance), obtain the angle needed for beam forming and perform initial synchronisation, especially can be used for the client be not scheduled for some time.In long evolving system, sounding reference signal transmission enhancement can be periodically or aperiodicity.When periodic sounding reference signal transmission enhancement, evolved base station sets client periodically transmits detection reference signal, up to client shutdown or till being reset.On the contrary, when using non-periodic detection reference signal transmission, only have when evolved base station proposes to client the requirement transmitting detection reference signal, client just transmits detection reference signal.In addition, the power for sounding reference signal transmission enhancement can be limited in a below particular value usually, and to avoid client when cell edge improves power, amplifier produces nonlinear distortion.
Please refer to Fig. 1, Fig. 1 is the schematic diagram of prior art one wireless telecommunication system.Client UE1 and UE2 all transmits detection reference signal in a frequency band, and it can comprise multiple resource block or subcarrier.Due to the position of client UE1 and UE2 and mobile behavior different, channel CH1 and CH2 that client UE1 and UE2 experiences is also different.The detection reference signal of evolved base station eNB by receiving from client UE1 and UE2, estimates the channel quality of channel CH1 and CH2.If the channel quality of channel CH1 is better than the channel quality of channel CH2, then evolved base station eNB distributes more or whole resources in client UE1.On the contrary, if the channel quality of channel CH2 is better than the channel quality of channel CH1, then evolved base station eNB distributes more or whole resources in client UE2.Because the client with better channel quality can use higher-order modulation and comparatively low rate coding, the quantity of the data transmitted and receive can be increased, thus improve power system capacity.In simple terms, evolved base station eNB distributes more or whole resources in the client with better channel quality.When the client with different channels quality can supply evolved base station eNB operation dispatching more, can further improve power system capacity.
It is noted that when client transmits detection reference signal in identical frequency band, must maintain the orthogonality between different detection reference signal and low mutual interference, evolved base station just can according to received detection reference signal, estimated channel quality.In long evolving system, the particular design sequence (as Zadoff-Chu sequence) that orthogonality between the detection reference signal detection frequency range that Interleaved FDMA accesses (interleavedfrequency-divisionmultipleaccess, IFDMA) by using, restriction client uses and use correspond to displacement circulation timei (cyclictimeshift) and basic sequence (basesequence) is reached.And low mutual interference is reached by using interference randomization, its to include for basic sequence between sequence group to jump (sequence-grouphopping) and cyclic shift jumps (cyclicshifthopping).
On the other hand, the client of long evolving system separately transmits a rectification reference signal (demodulationreferencesignal in uplink, DMRS) to network terminal, perform channel estimating for network terminal, simultaneous demodulation is performed to the data that client transmits.Be different from the detection reference signal of the larger frequency range of use, client use and physically link control channel (physicaluplinkcontrolchannel, PUCCH) or physically link shared channels (physicaluplinksharedchannel, PUSCH) identical resource block, upper transmission rectification reference signal in each subframe.On the other hand, be similar to detection reference signal, Interleaved FDMA access (interleavedfrequency-divisionmultipleaccess, IFDMA) and the particular design sequence (as Zadoff-Chu sequence) corresponding to displacement circulation timei (cyclictimeshift) and basic sequence (basesequence) then for maintaining the orthogonality between rectification reference signal, sequence group between basic sequence jumps (sequence-grouphopping) and cyclic shift jumps (cyclicshifthopping) then for reducing mutual interference.
Advanced Long Term Evolution (LTE-advanced, LTE-A) system is the advanced version of long evolving system, it includes rapid translating power rating, lifting cell edge usefulness, frequency range extension, coordinates multileaving/reception (coordinatedmultipointtransmission/reception, and the technology such as multiple-input and multiple-output (multi-inputmulti-output, MIMO) CoMP).
Advanced long evolving system uses the integrated (carrieraggregation of carrier wave, CA) to reach the object that frequency range extends, the two or more component carrier of the integrated polymerization of carrier wave (componentcarriers) is to reach the transfer of data of higher frequency range, therefore, advanced long evolving system by be polymerized 5 frequency ranges be the component carrier of 20MHz to support the frequency range up to 100MHz, wherein each component carrier all back compatible in the single carrier wave of 3GPPRe1-8 institute specification.Advanced Long Term Evolution specification supports continuous and discrete component carrier simultaneously, and each component carrier can comprise at most 110 resource block (resourceblock), therefore, by being polymerized discontinuous component carrier to increase frequency range elasticity.In addition, in the advanced long evolving system operating on time multiplex (time-divisionduplex, TDD) pattern, a component carrier is simultaneously for uplink (uplink, UL) and lower link (downlink, DL).
After the carrier wave of advanced long evolving system setting client is integrated, client can transmit and receive data on one or more component carrier to increase message transmission rate.In advanced long evolving system, evolved base station can according to the different uplink of client and lower FLCarrier integration capability, the uplink of the different number of configuration client and lower link component carrier.Further, the component carrier that client uses must include link primary component carrier (primarycomponentcarrier, and a uplink primary component carrier PCC), all the other component carriers are then respectively uplink or the secondary component carrier (secondarycomponentcarrier, SCC) of lower link.The quantity of uplink and the secondary component carrier of lower link is relevant to client end capacity and assignable Radio Resource, uplink and lower link primary component carrier are used in sets up and sets up wireless heterogeneous networks and transmission and receiving system information, advanced long evolving system does not allow to close uplink and lower link primary component carrier, but by the direct access communications channels routine change uplink of handover procedure and lower link primary component carrier.
In an advanced long evolving system, coordinate multileaving/reception, the transmission of the evolved base station tunable different clients signal that geographical position is different and reception by using.When client is when the edge of an evolved base station covering scope, client can receive the signal launched by multiple evolved base station, and the signal that client transmits also can be received by multiple evolved base station.For example, for lower link, by coordinating the running of multiple evolved base station, reduce the signal disturbing irrelevant with client, such as use scheduling or beam forming, also can strengthen the reception of client for signal, such as identical data are transmitted to client in multiple evolved base station.For uplink, multiple evolved base station can in conjunction with received client signal to strengthen signal quality.Therefore, when client is when the edge of the covering scope of an evolved base station, the link such as data rate and output rating usefulness increases because using coordination multileaving/reception.
Uplink multiple-input and multiple-output (uplinkMIMO, ULMIMO) technology by exchanging parallel data streams, to increase data rate, spectrum efficiency and power system capacity between evolved base station and client.Generally speaking, in order to realize uplink MIMO technique, evolved base station and client all need to configure multiple transmitting and reception antenna.But even if the configurable multiple transmitting in evolved base station and reception antenna, due to the volume that client is limited, most client only can configure single transmitting antenna and single reception antenna, and the advantage of uplink MIMO technique is thus limited.Therefore, advanced long evolving system uses uplink multi-user multiple-input and multiple-output (ULmultiuser-MIMO, ULMU-MIMO) technology to address this problem.By using uplink multi-user MIMO technique, the multiple client with a transmit antennas of evolved base station arrangements transmits data in identical frequency band, by processing the data that multiple client transmits simultaneously, realize increasing the advantages such as data rate, spectrum efficiency and power system capacity.
Because the method performing sounding reference signal transmission enhancement in long evolving system is only suitable for the client and the network terminal that use single component carrier, the method cannot be used in has the advanced long evolving system that carrier wave is integrated, coordinate multileaving/reception and uplink multi-user MIMO technique.Therefore, how use coordinate multileaving/reception and uplink multi-user MIMO technique when, on multiple component carrier, transmit the problem that detection reference signal system waits to solve, relevant parameter and agreement also need to extend or revise for advanced long evolving system.

According to flow process 40, during network terminal setting uplink multiple-input and multiple-output (as uplink multiple-input and multiple-output (ULMIMO)), coordination multileaving/reception and carrier wave are integrated, at least one function is in client, client uses at least one detection reference signal configuration in client particular probe reference signal configuration, component carrier particular probe reference signal configuration and community particular probe reference signal configuration, to perform sounding reference signal transmission enhancement at least one operation component carrier.Specifically, evolved base station can set uplink multiple-input and multiple-output relative to client is transparent (transparent) or nontransparent (non-transparent).Specifically, when can to set uplink multiple-input and multiple-output be transparent relative to client in evolved base station, contiguous evolved base station is without leave in conjunction with the detection reference signal that client transmits, or identical signal is transmitted to client in contiguous evolved base station, that is, client need not know that it is using uplink multiple-input and multiple-output in sounding reference signal transmission enhancement.On the other hand, when can to set uplink multiple-input and multiple-output be nontransparent relative to client in evolved base station, client knows that it is using uplink multiple-input and multiple-output in sounding reference signal transmission enhancement, and need configure according to used uplink multiple-input and multiple-output, adjustment sounding reference signal transmission enhancement mode.Therefore, when client configuration uplink multiple-input and multiple-output, coordinate multileaving/reception and carrier wave integrated at least one function time, can according to the above description and flow process 40 perform sounding reference signal transmission enhancement.
On the other hand, when the integrated configuration of the client specific carriers of client configuration more than one component carrier, according to detection reference signal configuration at least one in client particular probe reference signal configuration, component carrier particular probe reference signal configuration and community particular probe reference signal configuration, client can perform sounding reference signal transmission enhancement on multiple component carrier.Further, the parameter of client particular probe reference signal configuration can include a detection reference signal subframe, one Interleaved FDMA access (interleavedfrequency-divisionmultipleaccess, IFDMA) repetition factor, one length (duration), the quantity of one aperiodicity dynamic instrumentation reference signal configuration, one cycle (periodicity), one sub-frame offset (subframeoffset), one system bandwidth, one detection reference signal frequency range, one detection reference signal jump frequency range (hoppingbandwidth), one frequency domain position, one transmission comb (transmissioncomb), one space matching, one time multiplex (time-divisionmultiplexing, TDM) configure, at least one parameter in one sounding reference signal sequence and circulation timei displacement (cyclictimeshift).
In addition, in the specific signaling of client (as wireless heterogeneous networks (radioresourcecontrol, RRC) signaling) and the specific signaling in community (as Cell Broadcast CB signaling), at least one signaling includes client particular probe reference signal configuration.In other words, a part of client particular probe reference signal configuration transmitted by the specific signaling of client, and the specific signaling in another part client particular probe reference signal configuration Ze You community transmitted.Or, client particular probe reference signal configuration also can separately by the specific signaling of the specific signaling of client and community wherein a signaling transmitted.Similarly, in the specific signaling of the specific signaling of client (as radio resource control signaling) and community (as Cell Broadcast CB signaling), at least one signaling includes component carrier particular probe reference signal configuration.In other words, a part of component carrier particular probe reference signal configuration transmitted by the specific signaling of client, and the specific signaling in another part component carrier particular probe reference signal configuration Ze You community transmitted.Or, component carrier particular probe reference signal configuration also can separately by the specific signaling of the specific signaling of client and community wherein a signaling transmitted.
Such as, according to a specific purpose, plot planning etc., evolved base station can set client and perform sounding reference signal transmission enhancement according to different situations.For example, client can use identical, part is identical or different detection reference signal is configured at different transmission mode, to perform this sounding reference signal transmission enhancement.Client also can use identical, part is identical or different detection reference signal be configured at different uplink multiple-input and multiple-output configuration, the distinct beams etc. of such as different antenna port configuration, the configuration of different transmitting antenna, different transmission comb (transmissioncombs), different space matching (spatialconfiguration), different sounding reference signal sequence, different displacement circulation timei (cyclictimeshifts) and/or beam forming, to perform this sounding reference signal transmission enhancement.Or, client also can use identical, part is identical or different detection reference signal is configured at different uplink and coordinates multileaving/receptions and configure, such as different existing coordination community (activecoordinatingcells), different transmission comb, different time multiplex (time-divisionmultiplexing, TDM) configuration, different detection reference signal frequency range, different sounding reference signal sequence, different displacement circulation timei and/or different coordination multileaving/receive modes etc., to perform this sounding reference signal transmission enhancement.
