Description

Sending method, detection method and its device of control signaling

Technical field

The present invention relates to the communications field, in particular to a kind of sending method of control signaling, detection method and its Device.

Background technology

It is descending in Long Term Evolution (Long term evolution, referred to as LTE) system and LTE-Adavance systems Physical layer control signaling contain terminal need related downlink mandate (DL Grant) information of the downlink transfer known and The up-link for the uplink correlation that user equipment (also known as terminal, referred to as User Equipment, UE) needs to know is awarded (UL Grant) information is weighed, to indicate the related information of the various transmission such as transfer resource position, modulation coding mode, these physics Layer control signaling is transmitted on physical layer control channel PDCCH.Here physical layer control signaling is primarily referred to as physical layer The proprietary control signaling of user.

In the version (Release, abbreviation R) 8/9 of LTE system and the R10 of LTE-Adavance system versions, thing is transmitted Manage the physical layer control channel (Physical Downlink Control channel, referred to as PDCCH) one of layer control signaling Well matched put (Orthogonal Frequency Division Multiplexing, is referred to as in top n OFDM OFDM) sent on symbol, this N number of symbol is generally referred to as control signaling transmission region.

The available transmission resources of existing control signaling transmission region are divided into multiple CCE resource units, and control information accounts for It is allocated with resource in units of CCE, resource units CCE here can further be subdivided into multiple REGs again, one CCE is made up of multiple discontinuous REGs, and usually 9 REGs form a CCE, and further each REG is by multiple bases This resource units forms.

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

In the version after R10, in order to improve the transmission capacity of control channel, the control signaling of more users is supported, Design considers to open up new control channel region, and same UE control signaling transfer resource can be continuous time-frequency money Source, to support closed loop precoding technology, improve the transmission performance of control information.

Fig. 1 is the schematic diagram in the control signaling region of new and old edition in correlation technique, as shown in figure 1, this method is in original The R8/9/10 come PDSCH transmission region transfers fractional transmission resource and is used for new control signaling transmission region, can to control Closed loop precoding technology is supported during signalling processed, lifting control signaling capacity supports the control signaling of more users.

Here in the second control signaling transmission region, the proprietary demodulation pilot tone (DMRS) in R10 can be reused to solve regulation and control Signaling processed, supports precoding technique well.

Second control signaling transmission region can also support transmission diversity technology, although the first control signaling transmission region is Through diversity technique can be supported, but because the second control signaling transmission region can preferably carry out the interference coordination of minizone, Therefore it is also an admissible direction.

For base station, due to multiple regions be present, how special in these regions transmission user a technical problem is There is control information.

For terminal, due to the problem of control information a variety of transmission technologys and important transmission region one be present be as What detection control signaling region.

Physical Downlink Shared Channel (the Physical Downlink Shared defined in LTE/LTE-A agreement Channel, referred to as PDSCH) a variety of transmission modes, Tables 1 and 2 is a part therein.It can be seen that each transmit mould Formula really supports a variety of transmission technologys, therefore has multiple DCI format to need to detect, corresponding a variety of different transmission skills Art, such benefit are that the switching at runtime of a variety of transmission technologys can be supported under same transmission mode, but are needed more Blind check expense, compared to the blind check expense that only one descending control information format (DCI format) of inspection adds one times.

The downlink transfer pattern of table 1 illustrates table

The uplink transmission mode of table 2

In version before, terminal only needs the first control signaling region, current according to the method for former version, detection Corresponding a variety of different DCI format under PDSCH transmission pattern.

After new control signaling region and transmission technology is introduced, two kinds of processing methods are presently, there are.

Method one：

This method can keep close with the blind check number of former version, but because base station can not dynamically select to use The transmission region of the proprietary control signaling in family, and terminal can only detect a control signaling region, or a kind of control signaling Transmission means, therefore the transmission of control signaling is not very flexible, it is impossible to more dynamically switch over.

Method two：

Sent when each subframe in base station can be selected dynamically in the first control signaling region using transmission diversity technology User proprietary control information is sent in the second control signaling region according to the transmission technology demodulated based on UE specific RS User proprietary control information.User proprietary control information specifically refers to corresponding a variety of different DCI under current PDSCH transmission pattern format。

Terminal is first in the first control signaling region, according to the method for former version, the first control signaling region according to point The reception mode of collection detects corresponding a variety of different DCI format under current PDSCH transmission pattern, if detected specially There is control signaling then detection of end, if not detecting proprietary control signaling, UE is based in the second control signaling region Specific RS are demodulated to continue to detect, and detect a variety of different DCI format.

This method can cause control signaling more flexibly to be selected according to current transmission conditions in the first control signaling Region is flexible in the second control signaling area transmissions, comparison.But compared with former version, blind check number will increase a lot.
