Description

The transmission method of Downlink Control Information and device
Technical field
The present invention relates to communication technology, particularly relate to transmission method and the device of a kind of Downlink Control Information.
Background technology
(Long Term Evolution is called for short: LTE) in system, base station sends downlink data to terminal Long Term Evolution Time, scheduling time-frequency domain resources is carried this downlink data, e.g. transmitting physical DSCH Downlink Shared Channel in certain subframe (Physical Downlink Shared Channel is called for short: PDSCH), be carried on by downlink data on this PDSCH channel； Meanwhile, base station also can in this subframe transmitting physical downlink channel control (Physical Downlink Control Channel, be called for short: PDCCH), this PDCCH for bearing downlink control information (Downlink Control Information, It is called for short: DCI), this DCI such as includes downlink data resource location on PDSCH channel, the modulation coding mode etc. of use. First terminal (User Equipment is called for short: UE, is also subscriber equipment), when this subframe receives signal, will obtain on PDCCH DCI, the downlink data of carrying could be obtained on PDSCH channel further according to this DCI.Subframe is the unit of time in communication.Logical Often in time domain, a subframe occupies 1ms(millisecond), as shown in Figure 1.
In different subframes, the OFDM (OrthogonalFrequency that PDCCH takies in time domain Division Multiplexing, is called for short: OFDM) symbol there may be change；Such as, the PDCCH in some subframe takies 2 Individual OFDM symbol, the PDCCH in other subframes takies 3 OFDM symbol.Concrete, that PDCCH takies in subframe OFDM Symbolic number (being i.e. equivalent to this PDCCH position in the time domain of subframe) is to be indicated letter by the physical control format in each subframe (Physical Control Format Indicator Channel is called for short: PCFICH) indicate, believe at this PCFICH in road The information of road transmission is PCFICH numerical value, and this PCFICH numerical value is for representing the OFDM symbol number that PDCCH takies in the burst. Such as, if PCFICH numerical value is 2, then it represents that PDCCH takies 2 OFDM symbol numbers in the burst, UE just can be accordingly at this First OFDM symbol and second OFDM symbol in the time domain of subframe obtain the DCI that PDCCH transmits.
In traditional channel divides, first three OFDM symbol in subframe is used for PDCCH.But the PDCCH in extension (extended-PDCCH is called for short: in ePDCCH), the transfer resource for PDCCH is further extended.Can pass through further EPDCCH carrying is for obtaining the DCI of downlink data, and the resource location of this ePDCCH is positioned at tradition PDSCH channel occupancy On running time-frequency resource；When downlink data transmission exists traditional PDCCH and ePDCCH simultaneously, PCFICH numerical value is used for representing EPDCCH original position in time domain.Such as, if PCFICH numerical value is 2, then it represents that in the burst, ePDCCH is from time domain The 3rd OFDM symbol start map, and in time domain the first two OFDM symbol transmission remain PDCCH.After extension The resource of ePDCCH Yu PDSCH channel uses the rule of frequency division multiplexing, shown in Figure 1, and Fig. 1 is that prior art is descending controls letter The channel resource mapping graph of the transmission method embodiment of breath.PDCCH or ePDCCH generally occupies in a subframe in time domain Specific time-domain position, i.e. occupies certain period of time in subframe.And, PDCCH or ePDCCH generally can occupy one on frequency domain Fixed frequency range.As it is shown in figure 1, subframe is 1ms, ePDCCH in time domain can take up therein 0.2nd millisecond to the 1.0th Millisecond.
As above, UE, when receiving the downlink data of certain subframe, needs first to detect the PCFICH letter of this subframe By PCFICH numerical value, road, knows that PDCCH or ePDCCH position in this subframe (i.e. knows which in time domain take is Individual OFDM symbol), from corresponding OFDM symbol, receive the DCI of carrying on PDCCH or ePDCCH the most again.In prior art, The PCFICH channel that UE is mapped on Whole frequency band by detection, it is thus achieved that PCFICH numerical value；But, along with the development of LTE technology, In evolution version after Release 11, may support the UE of a kind of capabilities, this UE only supports the process of narrow band data Ability, i.e. can only data on receiving portion frequency domain, possibly cannot obtain the information of PCFICH channel (such as, by causing UE The frequency domain at PCFICH channel resource place is not belonging to the limit of power of this UE), and then just cannot learn that PDCCH or ePDCCH exists The position of this subframe, affects the acquisition of DCI and the reception of downlink data further.

Described SIB3 can represent predefined first subframe by following information, including: the son of described first subframe Frame identification or for obtain described first subframe subframe mark rule and parameter.The rule of concrete above-mentioned subframe mark Then may refer to embodiment four with contents such as parameters.
505, terminal receives described predefined first subframe；
506, terminal is based on predefined first physical control format, the pre-timing of first in predefined first subframe Position, territory receives Downlink Control Information from base station.
Wherein, described predefined first subframe is to be carried on by Downlink Control Information on the first predetermined time-domain position, eventually End need not detect PCFICH channel.
In superincumbent embodiment of the method, respectively illustrate the first subframe be standard regulation fixing subframe or by The adjustable subframe of certain SIB instruction, the whether setting means of which kind of subframe, about the selection of the first subframe, the most on earth Select which subframe in each frame to control information at the first predetermined time-domain position bearing downlink, can enter based on following rule OK: described first subframe includes: be used for sending the paging subframe of beep-page message (paging).Because sending the paging of paging Subframe, terminal receives, to correct, the paging that base station sends, and is also need according to PDCCH or ePDCCH transmission descending Control acquisition of information, so, for capabilities UE, the paging subframe sending paging is also required to what employing was preset PCFICH information so that capabilities UE need not detect PCFICH channel, it is ensured that paging is properly received by this UE.
Concrete, the first above-mentioned subframe to be realized and include paging subframe, can process based on following two ways:
A kind of mode is: do not change the mechanism sending paging；
Such as, for FDD system, the subframe numbers of the subframe for sending paging may is that 0,4,5,9, i.e. these four Subframe can send paging, for specific UE, is transmission paging in one of them subframe in these four subframes. So, if UE to be ensured is properly received paging and does not change the mechanism sending paging, sub-frame set i.e. can be included Subframe numbers is the sub-frame set of 0,4,5,9 these four subframes, is predefined as the sub-frame set of the first subframe, i.e. any of which subframe It is all predefined first subframe, is all to control information at the first predetermined time-domain position bearing downlink.Described 0,4,5,9 are permissible It is referred to as predetermined time-domain position, referred to as one frame of described sub-frame set is positioned at the set of multiple subframes of predetermined time-domain position.
In like manner, for TDD system, the subframe numbers of the subframe for sending paging may is that 0,1,5,6, can be by upper State four subframes corresponding to subframe numbers and be all predefined as the first subframe, aforementioned four subframe is all in the first position, pre-domain Put bearing downlink and control information, from regardless of whether UE receives which subframe aforementioned four subframe, can be the most pre-first Domain position acquisition is to paging.
This mode is comparable to fix the first subframe in fact, and ensures that the set of the first subframe includes above-mentioned four The subframe of individual transmission paging.Additionally, in FDD system or TDD system, except above-mentioned four for sending the son of paging Outside frame, it is also possible to other subframe is predefined as the first subframe.
Another way is: change the mechanism sending paging；
That is, it not all to control information at the first predetermined time-domain position bearing downlink in four above-mentioned subframes, but can With in the most wherein subframe, control information at the first predetermined time-domain position bearing downlink.Specifically can operate as follows:
First, the predefined sub-frame set including multiple subframe:
Such as, predefined sub-frame set is that { 0,4}, here predefined can be base station according to certain relevant with terminal Which subframe is a little parameters define for terminal scheduling.
Then, the common factor of described sub-frame set and beep-page message sub-frame set, described beep-page message sub-frame set bag are obtained Include multiple subframe for sending beep-page message:
Such as, the set of four subframes that beep-page message sub-frame set is in a kind of mode, such as, it is used for sending The subframe numbers of the subframe of paging may is that 0,4,5,9；Such as, for FDD system, determine above-mentioned predefined sub-frame set { 0,4} with { common factor of 0,4,5,9} occurs simultaneously for { 0,4}.
Then, according to the terminal iidentification of described terminal and the selection rule preset, determine from described common factor for The described paging subframe of described terminal transmission beep-page message:
Determining based on certain preset rules, common factor { after 0,4}, determines that the paging sent to capabilities UE is to occur simultaneously In which subframe on.This rule can be but not limited to: IMSI mod 2, IMSI are the mark of UE, and mod 2 is because handing over It is concentrated with two subframes.For example, it is assumed that the numerical value of the IMSI of UE is 3, then calculates based on above-mentioned rule, 3mod 2=1, i.e. calculate Result is 1, then the paging subframe of this UE is that #4 work song frame (i.e. sets when result of calculation is as 1, selects the #4 work song in occuring simultaneously Frame is as the paging subframe sending paging)；The numerical value assuming the IMSI of UE is 2, then calculate based on above-mentioned rule, 2mod 2= 0, i.e. result of calculation is 0, then the paging subframe of this UE is that #0 work song frame (i.e. sets when result of calculation is as 0, in selecting to occur simultaneously #0 work song frame as send paging paging subframe).Here the paging subframe for sending paging determined is also referred to as First subframe.
The processing mode of the mechanism of paging is sent, when base station knows that paging is destined to mental retardation based on above-mentioned changing During power UE, especially when the sub-frame set of predefined multiple subframes is not mated with beep-page message sub-frame set, just may be used in base station With based on which, determine the common factor of sub-frame set and beep-page message sub-frame set, and determine which subframe in common factor Send paging, this makes it possible to ensure that the subframe of this transmission paging is to control letter at the first predetermined time-domain position bearing downlink Breath, it is ensured that UE can be properly received paging on the basis of not detecting PCFICH channel.
