Description

The transmission method of Downlink Control Information and device
Technical field
The present invention relates to the communication technology, relate in particular to a kind of transmission method and device of Downlink Control Information.
Background technology
Long Term Evolution (Long Term Evolution, be called for short: LTE) in system, when base station sends downlink data to terminal, to dispatch time-frequency domain resources and carry this downlink data, for example (the Physical Downlink Shared Channel of transmitting physical DSCH Downlink Shared Channel in certain subframe, be called for short: PDSCH), downlink data is carried on this PDSCH channel; Simultaneously, base station also can be in this subframe transmitting physical downlink channel control (Physical Downlink Control Channel, be called for short: PDCCH), this PDCCH is for bearing downlink control information (Downlink Control Information, be called for short: DCI), this DCI for example comprises resource location, the modulation coding mode of use etc. of downlink data on PDSCH channel.Terminal (User Equipment, be called for short: UE, be also subscriber equipment) in the time that this subframe receives signal, by the DCI first obtaining on PDCCH, then could obtain the downlink data carrying on PDSCH channel according to this DCI.Subframe is the chronomere in communication.Conventionally in time domain, a subframe occupies 1ms(millisecond), as shown in Figure 1.
In different subframes, (OrthogonalFrequency Division Multiplexing, is called for short: OFDM) symbol may change the OFDM that PDCCH takies in time domain; For example, the PDCCH in some subframe takies 2 OFDM symbols, and the PDCCH in other subframes takies 3 OFDM symbols.Concrete, the OFDM symbolic number (being equivalent to the position of this PDCCH in the time domain of subframe) that PDCCH takies in subframe is by (the Physical Control Format Indicator Channel of the Physical Control Format Indicator Channel in each subframe, be called for short: PCFICH) indicate, be PCFICH numerical value in the information of this PCFICH transmission, this PCFICH numerical value is for representing the OFDM symbolic number that PDCCH takies in this subframe.For example, if PCFICH numerical value is 2, represent that PDCCH takies 2 OFDM symbolic numbers in this subframe, just first OFDM symbol in the time domain of this subframe and second OFDM symbol obtain the DCI of PDCCH transmission to UE accordingly.
In traditional channel distribution, the OFDM symbol of first three in subframe is for PDCCH.But at the PDCCH(extended-PDCCH of expansion, be called for short: ePDCCH), be further extended for the transfer resource of PDCCH.Can further carry the DCI for obtaining downlink data by ePDCCH, and the resource location of this ePDCCH is positioned on the running time-frequency resource of traditional PD SCH channel occupancy; In the time that downlink data transmission exists traditional PDCCH and ePDCCH simultaneously, PCFICH numerical value is for representing the original position of ePDCCH in time domain.For example, if PCFICH numerical value is 2, be illustrated in this subframe, three the OFDM sign-on mapping of ePDCCH time domain, and the first two OFDM symbol transmission in time domain remain PDCCH.The resource of the ePDCCH after expansion and PDSCH channel adopts the rule of frequency division multiplexing, and shown in Figure 1, Fig. 1 is the channel resource mapping graph of the transmission method embodiment of prior art Downlink Control Information.PDCCH or ePDCCH occupy the specific time-domain position in a subframe conventionally in time domain, occupy regular hour section in subframe.And PDCCH or ePDCCH can occupy certain frequency range conventionally on frequency domain.As shown in Figure 1, a subframe is 1ms in time domain, and ePDCCH can occupy wherein the 0.2nd millisecond to the 1.0th millisecond.
As above, UE is in the time receiving the downlink data of certain subframe, need to first detect the PCFICH channel of this subframe, know position in this subframe of PDCCH or ePDCCH (know take be which the OFDM symbol in time domain) by PCFICH numerical value, receive again accordingly the DCI of PDCCH or ePDCCH carrying from corresponding OFDM symbol.In prior art, UE, by detect the PCFICH channel shining upon on Whole frequency band, obtains PCFICH numerical value; But, along with the development of LTE technology, in evolution version after Release 11, may support a kind of UE of low ability, this UE only supports the disposal ability of narrow band data, the data on can only receiving unit frequency domain, by cause UE possibly cannot obtain PCFICH channel information (such as, the frequency domain at PCFICH channel resource place does not belong to the limit of power of this UE), and then just cannot learn PDCCH or the ePDCCH position in this subframe, further affect obtaining and the reception of downlink data of DCI.

Fig. 5 is the schematic flow sheet of the another embodiment of transmission method of Downlink Control Information of the present invention, the present embodiment is according to predefined the second physical control format, the second predetermined time-domain position carrying SIB in predefined the second subframe, and this SIB is used to indicate described predefined the first subframe; Wherein, described the second physical control format is used to indicate described the second predetermined time-domain position.The concept of the predetermined time-domain position in subframe can be with reference to the description of embodiment before.Optionally, second subframe of the present embodiment is for example the 5th work song frame in a frame, and a described subframe comprises ten subframes from No. zero to No. nine, and the SIB in the 5th work song frame is called SIB1, as shown in Figure 5, comprising:
401, terminal receives the 5th work song frame that base station sends;
Wherein, system information block SIB is mainly used in carrying some network access informations that base station sends to terminal etc., to make terminal access network accordingly; In fact base station has sent multiple SIB, such as SIB1, SIB2, SIB3 ... SIB1 is the SIB sending at first, and, the carrying position of SIB1 is fixed, be that the 5th work song frame in the fixing each frame sending by base station (being the 6th subframe in the time domain of every frame) sends, this SIB1 can be called the first system block of information.And the schedule information of also having carried other SIB in SIB1, such as dispatching cycle, to make terminal in the time receiving SIB1, also can know when other SIB receive according to schedule information.
In the present embodiment, will indicate described predefined the first subframe by SIB1.
402, terminal, according to the second predetermined time-domain position, is obtained SIB1 from the 5th work song frame, and learns predefined the first subframe by SIB1;
Wherein, terminal, in the time receiving the 5th work song frame, if obtain the information of SIB1 in the 5th work song frame carrying, is that the Downlink Control Information (information of for example PDCCH) in need to the 5th work song frame is dispatched.Concrete, for example, SIB1 is the broadcast message sending on PDSCH channel, the Downlink Control Information of PDCCH in the 5th work song frame is used to indicate SIB1 at resource location of PDSCH channel etc., terminal still will first receive the Downlink Control Information of PDCCH, know the resource location of SIB1 at PDSCH channel by this Downlink Control Information, then get the information of SIB1 carrying at corresponding PDSCH channel.
In the present embodiment, can in standard, be scheduled to, the 5th work song frame is at the second predetermined time-domain position carrying SIB1, and for example, this second predetermined time-domain position is the first two OFDM symbol.Like this in the time that low ability UE receives the 5th work song frame, just do not need to detect PCFICH channel, but directly according to the second predetermined time-domain position, know that the time-domain position at PDCCH place is (in the situation that strengthening PDCCH, can be the position that ePDCCH starts mapping), directly receive the Downlink Control Information of PDCCH; On PDSCH channel, obtain SIB1 according to this Downlink Control Information again.
The second described predetermined time-domain position and the first predetermined time-domain position, can be the same or different.If when both are different, can further in SIB1, carry the indication information of described the first predetermined time-domain position, for example, this indication information is 2, represents that PCFICH numerical value is 2, so just can obtain the first predetermined time-domain position is the first two OFDM symbol.
Described SIB1 can represent predefined the first subframe by following information, comprising: the subframe mark of the first subframe, or, the rule and the parameter that identify for obtaining the subframe of described the first subframe.
For example, what in SIB1, carry can be, (the 0th work song frame, the 4th work song frame, the 5th work song frame), the subframe of directly carrying predefined the first subframe of base station side identifies, and terminal can directly know that the first subframe is the 0th work song frame, the 4th work song frame accordingly like this ...Certainly, above-mentioned predefined the first subframe can be certain subframe or individual subframe set, and the arbitrary subframe in this subframe set is all the first subframe.
What again for example, in SIB1, carry can also be rule and the parameter of obtaining the subframe mark of described the first subframe; Such as, described rule can be but be not limited to: #n mod m=0; Wherein, #n is subframe numbers, the specifically subframe of the first subframe mark, and m is the parameter of carrying in SIB1, this parameter is for the auxiliary subframe mark that obtains the first subframe.Be exemplified below: suppose m=5, according to above-mentioned regular #n mod 5=0, the subframe mark of the first subframe obtaining should comprise: #0, #5, (#0, #5) is predefined subframe set, the arbitrary subframe in this set is the first subframe.
Terminal obtains after the above-mentioned indication information that is used to indicate described predefined the first subframe, just can know that, in the frame of follow-up reception, which subframe is the first subframe; And, in this first subframe, not needing to detect PCFICH channel, terminal can directly receive Downlink Control Information at the first predetermined time-domain position in these first subframes.
In the present embodiment, by the first subframe of the indicating predetermined justice of SIB1, or the indication information of the first predetermined time-domain position is carried in SIB1, the benefit of processing is like this, base station can be adjusted this predefined first subframe or the first predetermined time-domain position when needed, as long as the information after adjusting is carried in SIB1, than the mode of the fixing subframe in embodiment tri-, the transmission of subframe is more flexible.
403, terminal receives described predefined the first subframe;
Wherein, the first subframe that described terminal receives, is the subframe that the SIB1 in 402 indicates.For example, the indication information of supposing to be used to indicate the first subframe is that the first subframe mark is #0, #5, and terminal is in the time receiving the next frame of frame at SIB1 place, and subframe corresponding to #0, #5 is wherein exactly predefined the first subframe.

Wherein, can in standard, be scheduled to, the 5th work song frame is in the second predetermined time-domain position bearing downlink control information, like this in the time that low ability UE receives the 5th work song frame, just do not need to detect PCFICH channel, but directly according to the second predetermined time-domain position, receive the Downlink Control Information of PDCCH at corresponding OFDM symbol; On PDSCH channel, obtain SIB1 according to this Downlink Control Information again.
The SIB1 of the present embodiment is used to indicate the 3rd subframe, and the 3rd subframe refers to the subframe for carrying other SIB.Concrete, receive another SIB from the 3rd predetermined time-domain position of stating the 3rd subframe, be for example SIB3, this SIB3 is used to indicate described predefined the first subframe.What in SIB1, carry is the schedule information of this SIB3 and the subframe of the 3rd subframe mark; The SIB3 schedule information of carrying in SIB1 and the schedule information of other SIB are different; Because SIB3 need to have fixing dispatching cycle and also have fixing transmission subframe numbers on the basis of fixing dispatching cycle, for example, fixing by the 2nd work song frame transmission; So the schedule information of SIB3 comprises: the subframe mark (example the 2nd work song frame described above) of the 3rd subframe of the dispatching cycle of SIB3 and fixing carrying SIB3.
By the schedule information of above-mentioned SIB3, terminal just can determine which subframe is the 3rd subframe of carrying SIB3 be.
503, terminal receives described the 3rd subframe;
504, the three predetermined time-domain position of terminal from described the 3rd subframe receives another system information block, and described another system information block is used to indicate described predefined the first subframe;
In the present embodiment, carry in the 3rd subframe of for example SIB3 of other SIB, also carry such as SIB3 of other SIB at the 3rd predetermined time-domain position; Terminal, in the time receiving the 3rd subframe, can directly receive SIB3 at the 3rd described predetermined time-domain position.For example, the OFDM symbol corresponding from the 3rd predetermined time-domain position at PDCCH place gets Downlink Control Information, knows the resource location of SIB3 at the PDSCH channel of the 3rd subframe, and then receive this SIB3 according to this Downlink Control Information.
It should be noted that, the 3rd described predetermined time-domain position, with predefined the second physical control format in the second predetermined time-domain position, can be the same or different; In the time that both are different, in SIB1, also carry the indication information of described the 3rd predetermined time-domain position.Same, if described the first predetermined time-domain position is also variable, in SIB3, also carry the indication information of the first predetermined time-domain position.In above-mentioned SIB1, carry the indication information that carries the first predetermined time-domain position in the indication information of the 3rd predetermined time-domain position and SIB3, the two can exist simultaneously, be equivalent to the 3rd predetermined time-domain position and the first predetermined time-domain position is all variable, or also can only there is wherein any one, it is changeless being equivalent to another, such as, if only also carry the indication information of the 3rd predetermined time-domain position in SIB1, showing that the first predetermined time-domain position and the second predetermined time-domain position can be identical, is all fixed position default in standard.
In described SIB3, can represent predefined the first subframe by following information, comprise: the subframe mark of described the first subframe or the rule and the parameter that identify for obtaining the subframe of described the first subframe.The content such as rule and parameter of concrete above-mentioned subframe mark can be referring to embodiment tetra-.
505, terminal receives described predefined the first subframe;
506, terminal is based on predefined the first physical control format, and the first predetermined time-domain position in predefined the first subframe receives Downlink Control Information from base station.
Wherein, described predefined the first subframe is that Downlink Control Information is carried on the first predetermined time-domain position, and terminal does not need to detect PCFICH channel.
In superincumbent embodiment of the method, illustrate that respectively the first subframe is the fixing subframe of standard regulation or the adjustable subframe of being indicated by certain SIB, no matter be the setting means of which kind of subframe, about the selection of the first subframe, select on earth which subframe in each frame in the first predetermined time-domain position bearing downlink control information, can carry out based on following rule: described the first subframe comprises: for sending the paging subframe of beep-page message (paging).Because, send the paging subframe of paging, if the paging that the reception base station that terminal is wanted correct sends, also be to obtain according to the Downlink Control Information of PDCCH or ePDCCH transmission, so for low ability UE, the paging subframe that sends paging also needs to adopt default PCFICH information, make low ability UE not need to detect PCFICH channel, guarantee the correct reception of this UE to paging.
Concrete, realize the first above-mentioned subframe and comprise paging subframe, two kinds of mode processing that can be based on following:
A kind of mode is: do not change the mechanism that sends paging;
For example, for FDD system, for the subframe numbers of the subframe that sends paging can be: 0,4,5,9, these four subframes can send paging, for specific UE, are to send paging in one of them subframe in these four subframes.So, if guarantee that UE correctly receives paging and do not change the mechanism that sends paging, subframe set can be comprised to subframe numbers is the subframe set of 0,4,5,9 these four subframes, be predefined as the subframe set of the first subframe, wherein arbitrary subframe is all predefined the first subframe, is all in the first predetermined time-domain position bearing downlink control information.Described 0,4,5,9 can be called predetermined time-domain position, and described subframe set is called the set that is positioned at multiple subframes of predetermined time-domain position in a frame.
In like manner, for TDD system, the subframe numbers that is used for the subframe that sends paging can be: 0,1,5,6, subframe corresponding to above-mentioned four subframe numbers all can be predefined as to the first subframe, in above-mentioned four subframes, be all in the first predetermined time-domain position bearing downlink control information, no matter thereby UE receives which subframe in above-mentioned four subframes, can both directly get paging at the first predetermined time-domain position.
This mode is to be equivalent to the first subframe to fix in fact, and guarantees that the set of the first subframe has comprised the subframe of above-mentioned four transmission paging.In addition, in FDD system or TDD system, except above-mentioned four for sending the subframe of paging, other subframe can also be predefined as to the first subframe.
Another kind of mode is: change the mechanism that sends paging;
That is, be not in four above-mentioned subframes all in the first predetermined time-domain position bearing downlink control information, but can be only therein in a subframe, in the first predetermined time-domain position bearing downlink control information.Specifically can operate as follows:
First, predefine comprises the subframe set of multiple subframes:
For example, predefined subframe set is that { 0,4}, the predefine here can be which subframe base station defines for terminal scheduling according to some parameter relevant with terminal.
Then, obtain described subframe set and beep-page message subframe intersection of sets collection, the set of described beep-page message subframe comprises multiple for sending the subframe of beep-page message:
For example, the set of beep-page message subframe is the set of four subframes in a kind of mode, such as, for the subframe numbers of the subframe that sends paging can be: 0,4,5,9; For example, for FDD system, { 0,4} is with { common factor of 0,4,5,9} occurs simultaneously for { 0,4} to determine above-mentioned predefined subframe set.
Then,, according to the terminal iidentification of described terminal and default selective rule, from described common factor, be identified for sending to described terminal the described paging subframe of beep-page message:
Determining occuring simultaneously { after 0,4}, is in which subframe in common factor based on certain preset rules decision to the paging of low ability UE transmission.This rule can be but be not limited to: IMSI mod 2, and the mark that IMSI is UE, mod 2 is because have two subframes in occuring simultaneously.For example, the numerical value of supposing the IMSI of UE is 3, calculates based on above-mentioned rule, 3mod 2=1, be that result of calculation is 1, the paging subframe of this UE is #4 work song frame (set in the time that result of calculation is 1, the #4 work song frame in selection common factor is as the paging subframe that sends paging); The numerical value of supposing the IMSI of UE is 2, calculate based on above-mentioned rule, 2mod 2=0, result of calculation is 0, the paging subframe of this UE is #0 work song frame (set in the time that result of calculation is 0, the #0 work song frame in selection common factor is as the paging subframe that sends paging).Here determine for the paging subframe that sends paging also referred to as the first subframe.
Send the machine-processed processing mode of paging based on above-mentioned change, knowing paging when base station is while sending to low ability UE, especially in the time that the subframe set of predefined multiple subframes is not mated with the set of beep-page message subframe, base station just can be based on which, determine subframe set and beep-page message subframe intersection of sets collection, and determine which subframe in common factor sends paging, the subframe that so just can guarantee this transmission paging is in the first predetermined time-domain position bearing downlink control information, guarantee that UE can correctly receive paging on the basis of not detecting PCFICH channel.
