Embodiment
In the specific descriptions of following preferred embodiment, with reference to the accompanying drawing formed appended by a part of the present invention.Appended accompanying drawing shows by way of example and can realize specific embodiment of the present invention.The embodiment of example is not intended to limit according to all embodiments of the present invention.Be appreciated that under the prerequisite not departing from scope of the present invention, other embodiments can be utilized, also can carry out amendment that is structural or logicality.Therefore, following specific descriptions are also nonrestrictive, and scope of the present invention limited by appended claim.
First, the new carrier wave of lte-a system may be independent (standalone) carrier wave, also can be non-Independent Carrier Wave.Difference is between the two, standalone carrier wave both can as independently main plot (PCell), also can as be attached to certain main plot from community (SCell); But not the carrier wave of standalone then can only exist as from community.For these two kinds of carrier waves, the message flow carrying out EPHICH configuration is slightly different, but designs which configuration parameter about needs, i.e. the part of IE design is identical.Below for convenience for the purpose of, IE design part be illustrated for non-standalone carrier wave.
Figure 1 show a kind of configuration mode of EPHICH channel on the new carrier wave of lte-a system.In this configuration, EPDCCH and EPHICH lays respectively at different Physical Resource Block (physical resource block the is called for short PRB) centering in PDSCH region.As shown in the figure, EPHICH employs the part resource of the PRB centering distributing to it.Therefore in this configuration, UE must know which PRB couple this EPHICH uses, as shown in Figure 1.Further, UE also needs which resource element (resource element is called for short RE) knowing that this EPHICH uses PRB centering concrete, and about the assignment information of these RE, both can be the RE directly providing each distribution, also can be the enhancing resource element group (enhanced resource element group is called for short EREG) providing distribution.Fig .3 a show the example of so a kind of distribution.In figure all labels be 0 RE all belong to an EREG, be labeled as EREG0, all RE that is in EREG0 distribute to this EPHICH channel.In addition, due under this configuration, EPHICH is not included in EPDCCH, therefore also must inform the demodulated reference signal (Demodulation reference signal be called for short DMRS) of UE for this EPHICH of demodulation, as depicted in figure 3 a.In addition, EPHICH will adopt the process of scrambling, cell ID (cell ID) can be adopted to carry out scrambling, or introduce new Radio Network Temporary Identifier (radio network temporary identifier is called for short RNTI) and carry out scrambling, then this Radio Network Temporary Identifier also needs to notify UE.
As preferably, in the system of reality, in order to improve the efficiency of system, several UE can be divided into one group, all UE in this group share an EPHICH channel configuration, and all UE namely in group use same EPHICH configuration to receive HARQ feedback, and such grouping is called EPHICH group.And the HARQ feedback result that in group, each UE specifically receives is determined by sequence identifier (sequence identifier).Fig. 4 illustrate such EPHICH group.Have 6 UE in group, each UE corresponds to the ACK/NACK result of this UE from the corresponding bits position acquisition of the EPHICH result received according to the sequence identifier (0-5) of oneself.What the sequence identifier of each UE in respective EPHICH group had both been expressed as the part of EPHICH parameter informs UE, also can inform UE by what imply in up scheduling, such as, this UE can be used to be mapped as sequence identifier in the upper position of Resource Block that uses of row shared channel (physical unlink shared channel is called for short PUSCH) physically.
Figure 2 illustrate the another kind of configuration mode of EPHICH channel on the new carrier wave of lte-a system.In this configuration, EPHICH is comprised in EPDCCH.As shown in the figure, EPHICH employs the part resource of the PRB centering distributing to EPDCCH.In this case, PRB need not be comprised in EPHICH configuration information to distributing and the information of DMRS, because these information can be obtained by the configuration of EPDCCH.But, due in lte-a system, each UE can configure at most two cover EPDCCH collection, therefore when this configuration, must inform which cover EPDCCH collection this EPHICH of UE belongs to.In addition in this configuration, UE also needs which resource element (resource element is called for short RE) of knowing that this EPHICH uses PRB centering concrete.This can be informed by the above-mentioned mode directly providing RE or EREG equally, can also by providing the mode of the enhancing control channel element (enhanced control channel element is called for short ECCE) of distribution.Accompanying drawing 3b gives the example of so a kind of distribution.Accept accompanying drawing 3a, all RE of PRB centering is divided into 16 EREG (EREG0 to EREG15), and in accompanying drawing 3b, these 16 EREG constitute again 4 ECCE, and wherein ECCE0 contains EREG0, EREG4, EREG8 and EREG12.Namely all RE comprised in ECCE0 return this EPHICH to use.Same, EPHICH will adopt the process of scrambling, cell ID can be adopted to carry out scrambling, or introduce new Radio Network Temporary Identifier (radio network temporary identifier is called for short RNTI) and carry out scrambling, then this Radio Network Temporary Identifier also needs to notify UE.
Same, be also suitable for the collocation method of sequence identifier in EPHICH group in this configuration.
In a word, under the configuration of non-standalone, the parameter configured required for EPHICH can be included in a new IE, be sent to UE by the first message, make UE be received corresponding HARQ feedback under different situations.It should be noted that, specify according to existing agreement, when UE have sent data by PUSCH to base station on a certain subframe (n), then UE receives HARQ feedback by EPHICH in subframe (n+k), for FDD system, and k=4; For TDD system, k >=4.
Preferably, this first message can be RRC information, further, can be that (RRCConnectionReconfiguration) message is reshuffled in RRC connection.
Give the method for carrying out EPHICH setting on standalone carrier wave according to another embodiment of the invention.As previously mentioned, about the content of IE design, namely the part transmitting which configuration parameter to UE is needed to be identical, mainly be with the difference of a upper embodiment, standalone carrier wave as PCell, also can just mean that UE can carry out Stochastic accessing (random access is called for short RA) process on this carrier wave.Therefore, need when UE not yet access base station, just manage to inform the configuration of UE about EPHICH, in RA process, receive HARQ feedback for this UE.For this reason, the configuration parameter of EPHICH can be included in the second message, be sent by broadcast channel, when UE resides in this community, EPHICH configuration can be obtained by above-mentioned second message; After this, after UE successfully accesses this community, different EPHICH can be sent by aforementioned first message again and be configured to this UE, thus carry out the change of EPHICH configuration.The advantage of such design is, can send different EPHICH configurations in the first message and the second message, the configuration wherein in the second message is only for RA process, and layoutprocedure can be tried one's best simply, such as, use system default parameter.And the parameter in the first follow-up message the actual conditions (such as according to the quantity of UE access) current according to system can be optimized configuration, with elevator system performance.By the switching of two cover EPHICH parameters, meet the requirement of system flexible configuration.
Preferably, the second message is SIB message, and the first message is RRC connection establishment (RRCConnectionSetup) message.
