Description

Physical Resource Block collocation method and the device of user equipment specific search volume

Technical field

The present invention relates to moving communicating field, relate in particular to Physical Resource Block collocation method and the device of a kind of user equipment specific search volume.

Background technology

Along with the development of Mobile Communication Industry, and continuous growth to mobile data services demand, the requirement of the speed of people to mobile communication and service quality (Qos) is more and more higher, so before 3G (Third Generation) Moblie (3G) does not also have extensive commercialization, just start the research-and-development activity to next generation mobile communication system, wherein relatively be typically the Long Term Evolution (LTE that third generation partner program (3GPP) starts, Long Term Evolution, Long Term Evolution) project, the available maximum spectrum bandwidth of LTE system is 20MHz (megahertz).Along with the further evolution of network, evolution LTE (LTE-A), as the evolution system of LTE, can provide the spectral bandwidth up to 100MHz, supports more flexible higher-quality communication, and LTE-A system possesses good backwards compatibility simultaneously.In LTE-A system, have multiple component carriers (CC, component carrier), a LTE terminal can only be operated on the CC of some backward compatibility, and the stronger LTE-A terminal of ability can be transmitted simultaneously on multiple CC.Realize terminal transmission and the reception data in multiple component carriers simultaneously of LTE-A, thereby reach the object that promotes bandwidth.This technology is called as multi-carrier polymerizing technology.

In the research of present stage, on the basis of multi-carrier polymerizing technology, the LTE R11 stage is for frequency spectrum resource utilization rate, network energy-saving, and interference inhibition aspect between community has proposed new demand.In order to realize this purpose, new carrier wave (new carrier type has been proposed at present, be called for short NCT), apply by means of carrier aggregation technology, new carrier wave has a salient feature, in the time of design, do not need to consider backwards compatibility exactly, can apply more new technology therein.For example, in LTE R11, be defined as for new carrier wave at present, need and at least one compatible carrier wave pairing operation (also referred to as carrying out the operation of carrier aggregation mode with a compatible carrier wave), in new carrier wave, do not configure cell reference signals (the Cell-specific reference signals of LTE R8, be called for short CRS), to avoid adjacent cell to disturb at the serious CRS of cell edge, particularly under HetNet scene, the CRS between macrocell and Microcell disturbs.

Further, because the progress of LTE R11 is slower, finally consider the standard operation that can not complete NCT in timing node, so just the correlative study of NCT technology is postponed till in LTE R12, the content of having agreed in LTE R11 is still accepted.The standardization effort of LTE R12 does not also start at present, there is more company to think, in LTE R12, not only to continue to study the NCT of LTE R11, also need further to increase other NCT technology, for example propose independent operation NCT (standalone NCT), there is independent operation ability.In order to be different from the NCT in LTE R11, because the NCT in LTE R11 need to configure a backward compatibility carrier wave, so be called as dependent operation NCT (non-standalone NCT), NCT is owing to wherein having deleted local channel/signaling, so need to be by runing with the compatible carrier wave of its pairing in dependent operation.

Further, the right position of Physical Resource Block (PRB) that in independent operation NCT, the user equipment specific search volume (USS) of definite ePDCCH has taken is notified by high-level signaling, concrete, is to adopt UE dedicated mode to carry out.Can make like this PRB of the USS of UE configure the PRB couple of public USS to accomplishing the UE for partly needing, the for example UE for needing to cooperate in COMP, respectively by their USS of signal deployment at identical PRB to interior, be conducive to UE and reduce search volume, also can not affect the PRB configuration of the USS of other irrelevant UE.

Notify the right position of PRB of the USS of the ePDCCH of UE for adopting UE special RRC message, there is at present problem below: UE from descending access until set up the process of RRC connection, must need in random access procedure, wherein need to receive the msg4 in random access procedure, if msg4 adopts the Downlink Control Information (DCI) that sends scheduling in the USS of UE so, how about does UE know the right position of PRB at the USS place of oneself so? another problem is: suppose that UE has completed random access procedure by other means, so, base station need to send some special dedicated radio resources control protocol (RRC) message for UE, when now UE receives the Article 1 special RRC message of base station transmission, special RRC message is dispatched transmission by USS, is the USS that how about UE knows this Article 1 special RRC message of scheduling so those PRB centerings?

To sum up, existing PRB cannot effectively configure the right position of PRB of USS to collocation method, has affected the reliability of system.

Embodiment

In prior art, the PRB of the USS of UE is to being to send to UE by the special RRC message of UE, and first the transmission of special RRC message needs to set up RRC and connect so, at present, just needs PRB that UE knows USS to position setting up process that RRC connects.Or the PRB that just need to know USS in the time that UE receives Article 1 special RRC message is to position.

In order to address the above problem, embodiments of the invention provide Physical Resource Block collocation method and the device of a kind of user equipment specific search volume.

Hereinafter in connection with accompanying drawing, embodiments of the invention are elaborated.It should be noted that, in the situation that not conflicting, the combination in any mutually of the feature in embodiment and embodiment in the application.

First by reference to the accompanying drawings, embodiments of the invention one are described.

The embodiment of the present invention provides the Physical Resource Block collocation method of a kind of user equipment specific search volume, in the downstream message of system side equipment in random access procedure, increase to UE side apparatus and distribute PRB or the right configuration information of PRB, system side equipment uses described PRB or PRB to being UE side apparatus transmission ePDCCH.UE side apparatus, carrying out in the process of random access, just can be received as oneself and distribute PRB or the right configuration information of PRB in downstream message, after parsing configuration information, is known as PRB or the right position of PRB oneself distributed.Wherein, described PRB or PRB, to being for the USS of UE side apparatus distributes, hereinafter referred to as give tacit consent to PRB or the PRB couple of USS.The acquiescence PRB of USS or PRB are to being to use in the time not receiving the PRB of USS of special RRC message configuration or PRB to position for UE side apparatus.Below take PRB to as example explanation, for PRB to all can use PRB replace, here the USS that mainly depends on ePDCCH with what unit carries, and for example, when the USS of ePDCCH carries with OFDM unit, the PRB in the embodiment of the present invention is to all being replaced by OFDM.

Acquiescence USS PRB to be only in the embodiment of the present invention for convenience and rise title, the acquiescence USS in the embodiment of the present invention is exactly the USS of ePDCCH.System side equipment comprises base station, relay station, RRH, Home eNodeB etc., and UE side apparatus comprises mobile phone terminal (as UE), RRH, Home eNodeB etc.

What the embodiment of the present invention was concrete comprises that two schemes, the first are the right positional informations of PRB of carrying acquiescence USS by msg2, and the second is the right positional information of PRB of carrying acquiescence USS by msg4.

The PRB of described acquiescence USS is to being that one or more ePDCCH set distribute, for the carrying of the USS of ePDCCH; Or described acquiescence USS is the USS of one or more ePDCCH set.

The first scheme is described below, in the first scheme, take UE side apparatus as UE as example describes.

With reference to figure 1, be the schematic flow sheet of random access, it is msg1, msg2, msg3, msg4 that

label

1,2,3,4 wherein represents respectively.The information of the PRB that system side equipment is configured for indication acquiescence USS in the downstream message msg2 of random access to position, and send to UE.System side equipment increases the PRB that downlink resource PRB is acquiescence USS to the control information distributing distribution is used in msg2, when UE receives after msg2, just can therefrom know the right position of PRB of USS, thereby make UE in the time not receiving system side equipment and be by RRC dedicated signaling the PRB of USS oneself distributing, can use the PRB of acquiescence USS to carrying out work.

System side equipment is carried on the Downlink Control Information of msg2 public search space (the Common Search Space of the enhancing of ePDCCH, be called for short CSS) in or the PRB centering of CSS send to UE, and in DL-SCH, transmit msg2 according to Downlink Control Information to UE.UE is in the process of the random access of execution, and the Downlink Control Information to reception msg2 by the CSS of ePDCCH or the PRB of CSS then receives msg2 in DL-SCH according to Downlink Control Information.System side equipment adopts the RNTI arranging in advance to its scrambling in the time sending the Downlink Control Information of msg2, and the RNTI of agreement can be RA-RNTI.UE in the time receiving the Downlink Control Information of msg2, in the CSS sending or the PRB centering of CSS adopt the Downlink Control Information of agreement RNTI descrambling msg2.After descrambling is correct, UE just thinks that the Downlink Control Information of msg2 correctly receives.

The subframe that system side equipment sends msg2 is that UE transmission msg1 is corresponding to subframe or the time slot of system side, and corresponding relation is what appoint in advance.If the mode sending in employing window, so corresponding window length is appointed in advance, and system side equipment selects suitable subframe to send msg2 in window.UE, according to the mode of prior agreement, receives Downlink Control Information and the corresponding msg2 of msg2 in descending sub frame or time slot.Or UE is in the window of arranging, and subframe is surveyed the Downlink Control Information of msg2 one by one, until survey correct and receive msg2, or window length finishes.

The descending carrier that system side equipment sends msg2 is the corresponding descending carrier of up-link carrier that UE sends msg1, and corresponding relation is that configured in advance is good, and notifies to UE's in system broadcast message.The descending carrier that also can adopt system side equipment to send msg2 is that UE configures in msg1 and sends to system side equipment.Here can in msg1, increase the carrier wave indication information of msg2 transmission, with indication mechanism side apparatus, UE is desirably in the msg2 of transmission oneself in that descending carrier.

In the process of transmitting of msg2, system side equipment and UE agreement do not adopt HARQ mechanism, can reduce so unnecessary transmission.It is the PRB of acquiescence USS or the acquiescence USS distribution to (reality is all the USS of distribution ePDCCH for or the PRB of USS or USS, a name problem just here) that system side equipment comprises downstream grants (DL grant) information in msg2.

System side equipment distribute ePDCCH acquiescence USS PRB to time can use DCI.The PRB that UE determines acquiescence USS to time, know by the resource allocation information of resolving in DCI information.

System side equipment sends msg4 Downlink Control Information or msg4 the PRB centering of acquiescence USS or acquiescence USS, and in DL-SCH, sends msg4 according to Downlink Control Information.UE is at the Downlink Control Information of PRB midline detect msg4 of acquiescence USS or acquiescence USS, and in DL-SCH, receives msg4 according to Downlink Control Information.

System side equipment can also indicate msg4 to send to UE in that carrier wave in msg2, in the carrier wave of the transmission msg4 of the indication of UE in msg2, receives msg4.UE also can configure and oneself expect to send the carrier wave of msg4 in msg1 or msg3, and in the carrier wave that system side equipment is expected at UE, sending msg4 is UE.UE receives msg4 in the carrier wave of expecting.Be conducive to like this in multicarrier system, select suitable descending carrier according to the carrier aggregation capacity of UE.So, system side equipment needs in msg2 indication to send the right position of PRB of the acquiescence USS in the descending carrier of msg4 of UE.

System side equipment not for UE distribute ePDCCH USS PRB to time, the Downlink Control Information that uses the PRB of acquiescence USS or acquiescence USS to transmit send the Downlink Control Information of special RRC message signaling or the PDSCH of scheduling UE for UE.Equally, when UE do not receive system side equipment be the ePDCCH that oneself distributes USS PRB to time, UE receives the Downlink Control Information of special RRC message signaling or the Downlink Control Information of scheduling PDSCH transmission the PRB centering of acquiescence USS or acquiescence USS.

UE receives the random downstream message msg2 accessing, the information of the PRB of the indication acquiescence USS that parsing wherein configures to position, the right position of PRB of confirming to give tacit consent to USS.

Acquiescence USS PRB to the PRB that can be configured to USS by special RRC message by system side equipment to using for UE.

Preferably, the number that the PRB of the acquiescence USS of ePDCCH is right is a pair of.

First scheme is described below, still take UE side apparatus as UE as example describes.There is larger something in common with the first scheme, mainly exist the part of difference to be described below, still can continue to use above-mentioned scheme for other parts.

The information of the PRB of USS that system side equipment is configured for indication ePDCCH in the msg4 of random access to position, and send to UE.UE receives after msg4, knows that the PRB of USS of ePDCCH is to position from msg4.The PRB of the USS here, to being called the PRB couple of acquiescence USS of ePDCCH, is only appellation definition, and function sees above the description of face.

The PRB centering of system side equipment distributes the Downlink Control Information of msg4 acquiescence USS at msg2 sends.When UE carries out random access procedure, receive after msg2, just can know that the PRB of acquiescence USS, to position, receives the Downlink Control Information of msg4 from described position.Further in DL-SCH, receive msg4 according to Downlink Control Information.

Or the PRB centering that the Downlink Control Information of msg4 is carried on the CSS of ePDCCH or the CSS of ePDCCH by system side equipment sends, when UE carries out random access procedure, at the Downlink Control Information of the CSS of ePDCCH or the PRB centering of CSS reception msg4.Further in DL-SCH, receive msg4 according to Downlink Control Information.

It is to give tacit consent to the PRB of USS to distributing to the control information distributing that system side equipment increases Physical Resource Block in msg4.Here concrete PRB adopts DCI information to the control information form of distributing, and also can only indicate and distribute PRB or the right numbering of PRB, and the latter's signaling consumption is smaller.

When adopting notice PRB to when numbering, can arrange in advance to give tacit consent to quantity that the PRB of USS is right only for a pair of, this is the right purposes of PRB of considering the acquiescence USS of proposition, the PRB of acquiescence USS of ePDCCH is preferably set to for a pair of.The mode expense that adopts indication to number like this can be smaller.This mode is to be also applicable to scheme 1.

In the sending and receiving process of system side equipment and UE agreement msg4, use HARQ mechanism.To guarantee the reliability of msg4, thereby make aforesaid msg1, msg2, msg3 effective, if msg4 bust this, so aforesaid msg1, msg2, msg3 will lose efficacy.

System side equipment comprises the PRB couple that downstream grants information is acquiescence USS or acquiescence USS in msg4.This downstream grants information can be only PRB location information, also can comprise other information, for example MCS information.UE is known the right position of PRB of acquiescence USS after receiving msg4 from msg4, and the resource of applying in downstream grants information or downstream grants information is assigned as the PRB that gives tacit consent to USS to using.

The descending carrier that system side equipment sends msg4 is the corresponding descending carrier of up-link carrier that UE sends msg3, and corresponding relation is that configured in advance is good, and notifies to UE's in system broadcast message.The descending carrier that also can adopt system side equipment to send msg4 is that UE configures in msg1 or msg3 and sends to system side equipment.Here can in msg1 or msg3, increase the carrier wave indication information of msg4 transmission, with indication mechanism side apparatus, UE is desirably in the msg4 of transmission oneself in that descending carrier.

System side equipment not by special RRC message signaling be UE configuration ePDCCH USS PRB to time, system side equipment with acquiescence USS PRB to sending the Downlink Control Information of msg2, or the Downlink Control Information of msg4, or the Downlink Control Information of special RRC message, or the Downlink Control Information of the PDSCH of UE transmission.Further, system side equipment sends msg2, msg4, special RRC message, PDSCH in DL-SCH according to Downlink Control Information.UE is not receiving the right information of PRB of USS of ePDCCH of system side equipment configuration, UE receives the Downlink Control Information of msg2 the PRB centering of acquiescence USS, or the Downlink Control Information of msg4, or the Downlink Control Information of special RRC message, or the Downlink Control Information of the PDSCH of UE transmission.Further UE receives msg2, msg4, special RRC message, PDSCH in DL-SCH according to Downlink Control Information.

The descending carrier that system side equipment sends msg4 can configure and indicate in msg1 or msg2 or msg3.

System side equipment and UE agreement, when system side equipment be UE use PRB that special RRC message configured USS to time, preferentially use the PRB couple of the USS of system side equipment configuration.Wherein, system side equipment can use PRB pair of special RRC message signal deployment USS with the PRB of acquiescence USS to overlapping.

The following describes at the PRB of acquiescence USS that has obtained ePDCCH rear, how concrete uses these PRB to the mapping (mapping of the actual USS of being or eCSS) for ePDCCH.Use K to represent the total number of the set that the PRB of ePDCCH is right or represent the total number of ePDCCH set, set be in advance using several PRB to as a set, will gather and indicate to UE, UE retrieves USS or the CSS of ePDCCH in the PRB of set-inclusion.For example, 2 of set-inclusions or 4 or 8 PRB couple, the PRB of set-inclusion represents with N number.PRB in a set, to being discrete, can be also continuous, represents number and the continuous PRB number to the set that form of discrete PRB to the set forming, K >=KL+KD respectively with KL and KD.For example, while stipulating K=2, KL and KD can combine according to mode below:

{KL＝1，KD＝0}，{KL＝0，KD＝1}，{KL＝1，KD＝1}，{KL＝0，KD＝2}，{KL＝2，KD＝0}。

The value of N is { 2,4,8}.

Further regulation, for the USS of the ePDCCH of independent operation NCT, except using above-mentioned mode, also comprises below:

KL and KD adopt default configuration or adopt signaling is UE indication.If employing default configuration, for example: the configuration of regulation KL and KD is only the one in above-mentioned combination and combination below, K=3, KL and KD are combined as { KL=0, KD=1}, { KL=1, KD=0}, { KL=0, KD=2}, { KL=2, KD=0}, { KL=1, KD=1}, { KL=0, KD=3}, { KL=1, KD=2}, { KL=2, KD=1}, { KL=3, KD=0}.

If adopting signaling is UE indication, signaling is that UE sends by broadcast system information or special RRC message so, and concrete set K, KL, KD or N value can be given the UE needing by this signaling.

The USS of ePDCCH in independent operation NCT, for above-mentioned N value, can adopt 2 or 4.Or according to system bandwidth definition acquiescence N value, the N value that different system bandwidth is corresponding different.For example, the relation shown in following table 1.Also can adopt the predefine mode of table 2.

Further, for independent operation NCT, indicating the acquiescence PRB of ePDCCH to rear, also existing and need to indicate ePDCCH specifically to shine upon from that OFDM sign-on of PRB centering, namely initial OFDM symbol.Here for the different acquiescence OFDM symbol original position of dissimilar subframe definition, or be fixed as the 3rd or 4 OFDM be primary sign, further the initial OFDM symbol of the PDSCH of ePDCCH scheduling is identical with the initial OFDM symbol of ePDCCH.For example, when MBSFN subframe corresponding to PMCH, the initial OFDM symbol of acquiescence ePDCCH is the 3rd OFDM symbol; The initial OFDM symbol of acquiescence ePDCCH corresponding to conventional subframe is the 4th OFDM symbol.

Table 1

Table 2

Further, for NCT carrier wave, DMRS scramble sequence initial parameter X is the C-RNTI of community ce11ID or UE or the interim C-RNTI of UE.The position of ePDCCH corresponding initial eCCE in described PRB set is determined according to Hash (HASH) function.

When the ePDCCH of descending carrier sends descending scheduling, the initial position of the PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) in its corresponding up-link carrier configures in SIB.Further, before not receiving the relevant USS configuration of relevant ePDCCH RRC message, UE uses the PUCCH initial position of acquiescence, for example, use the PUCCH that ePDCCH is corresponding ₍₁₎position, or, in ePBCH or SIB, configure its initial position.In the time that UE does not receive the configuration information of the configuration information of ePDCCH set or the acquiescence USS of ePDCCH, UE uses PUCCH corresponding to ePDCCH ₍₁₎position, or UE uses the position of the PUCCH receiving from ePDCCH or SIB.
