Description

The detection method and device of control channel

Technical field

The present invention relates to the communications field, in particular to the detection method and device of control channel.

Background technology

It is descending in Long Term Evolution (Long term evolution, referred to as LTE) system and LTE-Adavance systems It is upper that the DL Grant information and UE needs that physical layer control signaling contains the downlink transfer correlation that terminal needs are known are known To indicate, transfer resource position, modulation coding mode etc. are various to transmit related information to the related UL Grant information of row transmission, These physical layer control signalings are transmitted on physical layer control channel PDCCH.Here physical layer control signaling is mainly Refer to the proprietary control signaling of user of physical layer.

In the R10 of version (Release, referred to as R) 8/9 and LTE-Adavance system versions of LTE system, transmission Before the physical layer control channel (Physical Downlink Control channel) of physical layer control signaling is generally disposed at On N number of OFDM (Orthogonal Frequency Division Multiplexing, referred to as OFDM) symbol Send, commonly referred to as this N number of symbol is control signaling transmission region.

The available transmission of existing control signaling transmission region (the first control signaling transmission region, the first control signaling region) Resource is divided into multiple CCE (control channel unit) resource units, and control information is taken resource and divided in units of CCE Match somebody with somebody, resource units CCE here can further be subdivided into multiple REGs again, and a CCE is by multiple discontinuous REGs groups Into usually 9 REGs constitute a CCE, and further each REG is made up of multiple basic resources units.

Proprietary and publicly-owned control signaling is all transmitted by resource units of CCE.Then corresponding REG (RE are mapped to Group, RE group) in resource, be further mapped to multiple PRB (Physical Resource Block) (Resource element, referred to as It is RE) in (least resource unit).Terminal carries out blind Detecting generally according in the following manner：Calculate proprietary control signaling, publicly-owned control The original position of signaling processed, here we be primarily upon proprietary control signaling：

Table：Illustrate table

It can be seen that the control signaling transfer resource of user's distribution is not continuous, prelisted to closed loop in multi-antenna systems Code technology out tape comes many difficult, hence in so that control signaling region can only be difficult to use closed loop using diversity technique prelisting Code technology.Main cause is that demodulation pilot design and the information feedback aspect in the first control signaling region have very big Control signaling is all only to support discontinuous resource transmission and diversity technique in design difficulty, therefore existing version.

In version after R10, in order to improve the transmission capacity of control channel, the control signaling of more users is supported, New control channel region (the second control signaling transmission region, the second control signaling region) is opened up in design, and Fig. 1 is correlation technique New and old edition control signaling region schematic diagram, the control signaling transfer resource of same UE can be continuous time-frequency money Source, to support closed loop precoding technology, improves the transmission performance of control information.

This method transfers fractional transmission resource for new control letter in the PDSCH transmission region of original R8/9/10 Transmission region is made, closed loop precoding technology is supported when can cause that control signaling is transmitted, lifting control signaling capacity supports more The control signaling of individual user.

Separately below from detection resource granularity, pilot frequency port, transmission means, modulation system, etc. aspect introduce The detection method of control channel.

Typically, since it is more to notify that the control information after the encoded modulation of terminal will take without extra information Few transfer resource, therefore, base station and terminal can arrange several sizes for taking resources, and base station can be come with a kind of size therein Send the control information after coded modulation, several resource sizes of the terminal meeting blind Detecting in agreement.It is general to define a basic money Source unit eCCE (enhanced control channel unit), this is similar with the function of former CCE, can be with the second control area eCCE Borrow the definition of early version CCE or slightly make an amendment, it is also possible to newly defined.Then, control signaling can be defined based on eCCE Different aggregation levels, such as 1,2,4,8, or 1,2,4 or 1,3,5,7 etc..So different aggregation levels are just represented Different resource size.Terminal also just more targetedly carrys out blind Detecting this several aggregation level.In the second control signaling Transmission region, can reuse the proprietary demodulation pilot tone (DMRS) in R10 to demodulate control signaling, and precoding skill is supported well Art.DMRS is also referred to as being UE Specific RS, and similarly hereinafter, main effect is demodulated with control signaling or data, it is specific this In refer to descending control signaling information demodulation.In early version, its mainly for data message demodulation design, have 8 it is right The DMRS port answered, maximum supports 8 layers, respectively Port 7-14.Typically only use 4 ports in the second control signaling region It is Port7-10 for demodulating control signaling.

Illustrated with the application of existing mode.Fig. 2 is that the resource in the RB of correlation technique divides close corresponding with port Be one schematic diagram, as shown in Fig. 2 corresponding relation one has problems in that, the pilot frequency port of this mode in minizone or Universal time coordinated underaction between transmission node.And be that MU-MIMO is dumb, Fig. 3 be resource in the RB of correlation technique divide with The schematic diagram of port corresponding relation two, as shown in figure 3, corresponding relation two introduces the blind Detecting of multiple Port for all situations Although blind check complexity very flexibly can be increased.

Second control signaling region can may be incorporated into some more new characteristics, such as new modulation system is Guarantee robustness, the control channel PDCCH transmitted in the first control area in early version only supports the modulation system of QPSK, But due to the development of MIMO technology, the closed-loop MIMO based on feedback can preferably to support 16QAM modes, in addition, for The preferable UE of local channel environment also has ready conditions and supports 16QAM even 64QAM.Therefore it is a kind of to consider it is the tune for introducing 16QAM Mode processed even can contemplate and introduce 64QAM.

Prior art is always to detect two kinds of modulation systems for all detections in the second control signaling region：QPSK and 16QAM, or QPSK, 16QAM, 64QAM are like this relative to only detecting a kind of situation, blind check number of times can double or Twice.

Transmission diversity technology can also be supported in the second control signaling transmission region, although the first control signaling transmission region Diversity technique can be supported, but the interference association of minizone can be preferably carried out due to the second control signaling transmission region Adjust, therefore be also an admissible direction.Can be in the first control signaling area transmission region if terminal wishes to do diversity Or second the diversity region of control signaling transmission region be transmitted.
