Description

The sending method of control signaling, detection method and device thereof

Technical field

The present invention relates to the communications field, in particular to a kind of sending method, detection method and device thereof of controlling signaling.

Background technology

At Long Term Evolution (Long term evolution, abbreviating LTE as) down physical layer control signaling has comprised relevant down link mandate (DL Grant) information and the subscriber equipment of downlink transfer that terminal need know and (has claimed terminal again in system and the LTE-Adavance system, User Equipment, abbreviate UE as) uplink grant (UL Grant) information that the uplink that need know is relevant, indicate the transfer resource position, the information that various transmission such as modulation coding mode are relevant, these physical layer control signalings are transmitted at physical layer control channel PDCCH.The physical layer control signaling here mainly refers to the proprietary control signaling of user of physical layer.

Version (Release in the LTE system, be called for short R) 8/9 and the R10 of LTE-Adavance system version in, physical layer control channel (the Physical Downlink Control channel of physical layer for transmission control signaling, abbreviate PDCCH as) generally be configured in top n OFDM (Orthogonal Frequency Division Multiplexing, abbreviate OFDM as) send on the symbol, generally claim this N symbol to be control signaling transmission region.

The available transmission resources of existing control signaling transmission region is divided into a plurality of CCE resource units, it is that unit distributes with CCE that control information takies resource, the resource units CCE here can further be subdivided into a plurality of REGs again, a CCE is made up of a plurality of discontinuous REGs, generally be that 9 REGs constitute a CCE, further each REG is made up of a plurality of basic resources units again.

The control signaling transfer resource that distributes of user is not continuous as can be seen, implements to bring a lot of difficulties in multiaerial system the closed loop precoding technique, therefore makes the control signaling area can only use diversity technique and is difficult to use the closed loop precoding technique.Main cause is that demodulation pilot frequency design and the channel condition information feedback aspect in the first precoding zone has very big design difficulty, and therefore the control signaling all is only to support discontinuous resource transmission and diversity technique in the existing version.

In the version after R10, in order to improve the transmission capacity of control channel, support the control signaling of more users, design considers to open up new control channel zone, and the control signaling transfer resource of same UE can be continuous running time-frequency resource, to support the closed loop precoding technique, improved the transmission performance of control information.

Fig. 1 is the schematic diagram of the control signaling area of new and old edition in the correlation technique, as shown in Figure 1, this method is transferred the part transfer resource for new control signaling transmission region at the PDSCH of original R8/9/10 transmission region, can promote the control signaling that the control signaling capacity is supported more users so that control signaling when transmission supported the closed loop precoding technique.

Here at the second control signaling transmission region, the proprietary demodulation pilot frequency (DMRS) that can reuse among the R10 comes demodulation control signaling, well supports precoding technique.

The second control signaling transmission region also can be supported transmit diversity technique, though the first control signaling transmission region can be supported diversity technique, but because the second control signaling transmission region can better carry out the interference coordination of minizone, also be an admissible direction therefore.

For the base station, owing to there are a plurality of zones, a technical problem is how to send user proprietary control information in these zones.

For terminal, because control information exists multiple transmission technology and important problem of transmission region are how to detect the control signaling area.

Defined the multiple transmission mode of Physical Downlink Shared Channel (Physical Downlink Shared Channel abbreviates PDSCH as) in the agreement of LTE/LTE-A, table 1 and table 2 are a part wherein.Can see each transmission mode actual be to support multiple transmission technology, therefore there are a plurality of DCI format to need to detect, corresponding multiple different transmission technology, such benefit is to support the dynamic switching of multiple transmission technology under same transmission mode, but need more blind check expense, increased by one times blind check expense than only examining a descending control information format (DCI format).

Table 1 downlink transfer pattern signal table

Table 2 uplink transmission mode

In version before, terminal only needs the first control signaling area, according to the method for former version, detects multiple different DCI format corresponding under the current PDSCH transmission mode.

After having introduced new control signaling area and transmission technology, there are two kinds of processing methods at present.

Method one:

The base station uses transmit diversity technique to send user proprietary control information or send user proprietary control information in the second control signaling area according to the transmission technology based on UE specific RS demodulation in the first control signaling area, and fixingly in a period of time only uses a kind of transmission technology to send in a zone.And the base station informs that by high-level signaling it sends the zone position information of user proprietary control information to terminal in a period of time.User proprietary control information specifically refers to multiple different DCI format corresponding under the current PDSCH transmission mode.

Terminal is determined surveyed area according to the high-level signaling that the base station issues, if base station notice terminal detects in the first control signaling area, then according to the method for former version, receive mode in the first control signaling area according to diversity detects multiple different DCI format corresponding under the current PDSCH transmission mode, if base station notice terminal detects in the second control signaling area, then transferring to detect multiple different DCI format in the second control signaling area based on UE specific Reference Resource (UE specific RS) solution.

It is close with the blind check number of times of former version that this method can keep, but because the base station can not be selected the transmission region of the proprietary control signaling of user dynamically, and terminal can only detect a control signaling area, or a kind of transmission means of controlling signaling, therefore the transmission of controlling signaling is not very flexible, can not switch more dynamically.

Method two:

Use transmit diversity technique to send user proprietary control information or control the signaling area second in the first control signaling area when each subframe of base station can be selected dynamically and send user proprietary control information according to the transmission technology based on UE specific RS demodulation.User proprietary control information specifically refers to multiple different DCI format corresponding under the current PDSCH transmission mode.

Terminal is earlier in the first control signaling area, method according to former version, receive mode in the first control signaling area according to diversity detects multiple different DCI format corresponding under the current PDSCH transmission mode, if detected proprietary control signaling then detection of end, if do not detect proprietary control signaling, then transfer to continue to detect based on UE specific RS solution in the second control signaling area, detect multiple different DCI format.

This method can be so that the control signaling be chosen in the first control signaling area according to current transmission conditions more flexibly or in the second control signaling area transmission, compares flexibly.But compared with former version, the blind check number of times will increase a lot.

Detection number of times at control signaling in the correlation technique is many, causes the lower problem of efficient, does not propose effective solution at present as yet.
