Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, be understandable that described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
The technical scheme that following examples of the present invention provide is applicable to wireless communication system, goes for first transmission or the control information of the data of transmission again in LTE and/or the LTE-A system.
The embodiment of the invention one provides a kind of sending method of controlling signaling, and present embodiment one applied scene is: a kind ofly control signaling can to indicate the defeated pattern of the multi-antenna transmitting that uses in the data transfer be multi-antenna multiplexed or multi-antenna diversity.Above-mentioned transmission can be transmitted two data transmission blocks, comprises the control information that is used to indicate above-mentioned two data transmission blocks in this control signaling, and the state of above-mentioned two data transmission blocks can be respectively to enable or disable.The enabled state of described data transmission block refers to that this data transmission block is transmitted in this transmission, or these data transmission block carrying data; Promptly in once transmitting, this data transmission block is not transmitted the disable state of described data transmission block, or this data transmission block does not carry data.As shown in Figure 1, the sending method of the control signaling that provides of present embodiment comprises the steps:
Step 101: the content of the control signaling that the transmission of base station side specified data is corresponding;
Wherein, the content of described control signaling comprises: the defeated pattern of the multi-antenna transmitting that described transfer of data is used, with two data transmission block control information corresponding in the described transfer of data, described control information comprises corresponding respectively the enabling/the disable state of described two data transmission blocks.
Above-mentioned base station side can refer to one or more base stations, and therefore, the method that the embodiment of the invention provides is both applicable to single cell scenario, also applicable to many cell scenario.
Two data transmission block control information corresponding can also comprise in the above-mentioned transfer of data: two data transmission block MCS (modulation coding mode, Modulation and coding scheme) separately; Two data transmission block RV (redundancy versions Redundancy version) separately; Two data transmission block NDI (new bag indication, New data indicator) separately etc.
Above-mentioned two data transmission blocks are corresponding respectively enables/and the disable state is specifically as follows:
Under the multi-antenna diversity pattern, the enabling an of data transmission block/disable control information is set to enable, and the enabling of another disable data transmission block/disable control information is set to disable.Because, under the multi-antenna diversity pattern, only transmit a data transmission block, promptly have only a data transmission block for enabling; Another data transmission block is a disable.Perhaps, under multi-antenna multiplexed pattern, the state of two data transmission blocks can be made as respectively and enable or disable.
In above-mentioned control information, the method for expressing of described enabling/disable state can comprise: at DCI (descending control signaling, Downlink Control Information) in, MCS (modulation coding mode, Modulation and coding scheme) position and RV (redundancy versions Redundancy version) can this data transmission block disables of joint instructions, for example the MCS value is 0, the RV value is that to indicate this data transmission block at 3 o'clock be the disable state, and it is enabled state that other values are indicated this data transmission block.Also can be provided for representing enabling or the information bit of disable state of data transmission block separately.
Step 102: if described base station side determines that first data transmission block is an enabled state in described two data transmission blocks, second data transmission block is the disable state, then uses the idle control information position of the described second data transmission block correspondence to indicate the multi-antenna transmitting of described transfer of data use to fail pattern.
Need to prove that above-mentioned first data transmission block and second data transmission block are used for from distinguishing two data transmission blocks nominally, do not represent the actual transmissions order of two data transmission blocks in transfer of data.
The idle control information position of the above-mentioned second data transmission block correspondence can be the new bag indication information position of the second data transmission block correspondence; Wherein, this new bag indication information position indicates described second data block for just passing the information bit of data block or re-transmitting data block for being used for when described second data block is enabled state.
For example, defeated pattern is a multi-antenna diversity if the multi-antenna transmitting of this transmission is determined in above-mentioned base station, then because described disable data transmission block does not need to transmit data, there is idle control information position in described disable status data transmission block control information corresponding, for example, this data transmission block disable state is indicated in MCS and RV position, for busy; It is new biography packet or retransmission data packet may that NDI no longer needs to indicate this data transmission block, is idle control information position.The defeated pattern of the multi-antenna transmitting that therefore can use the transmission of NDI designation data to use.Again for example, also can use independent information bit to represent under the situation of enabling of data transmission block or disable state, the defeated pattern of the multi-antenna transmitting that utilizes the transmission of MCS and/or RV designation data to use.
The mode that the multi-antenna transmitting that the idle control information position of the above-mentioned use second data transmission block correspondence indicates described transfer of data to use is failed pattern can comprise:
If the defeated pattern of the multi-antenna transmitting that transfer of data is used is the multi-antenna diversity pattern, then the value with described idle control information position is made as designated value;
If the defeated pattern of the multi-antenna transmitting that transfer of data is used is multi-antenna multiplexed pattern, then the value with described idle control information position is made as other outer value of designated value.
For example, above-mentioned idle control information position is set to designated value, and indication current multi-antenna transmission mode is the multi-antenna diversity pattern.Above-mentioned designated value can be made an appointment for base station side and UE side, or the value that is used to indicate the multi-antenna diversity pattern of communicating by letter both sides are known altogether with the UE side by base station side.Other outer value of above-mentioned designated value can be the value of setting according to control signaling design requirement, and in the method that the embodiment of the invention provides, this value can be used to indicate multi-antenna multiplexed pattern simultaneously.For example, the NDI position value of the data transmission block of agreement disable state is 0 o'clock, and the data transmission block of indication enabled state does not use the multi-antenna diversity pattern; The NDI value of the data transmission block of disable state is 1 o'clock, and the data transmission block of indication enabled state uses the multi-antenna diversity pattern.Perhaps, the NDI position value of setting the data transmission block of disable state is 0 o'clock, and the data transmission block of indication enabled state uses the multi-antenna diversity pattern; The NDI value of the data transmission block of disable state is 1 o'clock, and the data transmission block of indication enabled state uses multi-antenna multiplexed pattern.
Step 103: the control signaling that sends described transfer of data correspondence to UE.
The method that is provided according to the embodiment of the invention one, by utilizing the defeated pattern of idle control information position indication multi-antenna transmitting in the control signaling, realized under the situation that does not increase the control information position, order control signaling can indicate multi-antenna transmitting to fail pattern, therefore the embodiment of the invention need not increase new signaling consumption, effectively saved the signaling transfer resource, realized simple and convenient.
The embodiment of the invention two provides a kind of method of reseptance of controlling signaling, and its application scenarios is identical with embodiment one applied scene, can be used in to receive that the base station sends control signaling among the embodiment one.As shown in Figure 2, this method may further comprise the steps:
The control signaling of the transfer of data correspondence that step 201, UE reception base station side issue;
Wherein, the content of described control signaling comprises: the defeated pattern of the multi-antenna transmitting that described transfer of data is used, with two data transmission block control information corresponding in the described transfer of data, described control information comprises corresponding respectively the enabling/the disable state of described two data transmission blocks.
The content of above-mentioned control information and related definition can not repeat them here with reference to described in embodiment one step 101.
If step 202 UE determines that according to described control signaling first data transmission block is an enabled state in described two data transmission blocks, second data transmission block is the disable state, and then UE determines the defeated pattern of multi-antenna transmitting that above-mentioned transfer of data is used according to the idle control information position of the above-mentioned second data transmission block correspondence;
For example: if one of them data transmission block is for enabling, another data transmission block is a disable, base station side can be made an appointment with the UE side or be indicated the defeated pattern of multi-antenna transmitting of current transmission by certain or some idle control information positions of the agreement second data transmission block correspondence of communicating by letter is multi-antenna diversity or multi-antenna multiplexed, and concrete indicating means can be with reference to executing described in example one step 102.UE can be known the defeated pattern of multi-antenna transmitting of current transmission by the defeated pattern indicating bit of the multi-antenna transmitting that reads above-mentioned agreement.
Need to prove that above-mentioned first data transmission block and second data transmission block are used for from distinguishing two data transmission blocks nominally, do not represent the actual transmissions order of two data transmission blocks in transfer of data.
Step 203:UE carries out data processing according to the defeated pattern of described definite multi-antenna transmitting.
The method that is provided according to the embodiment of the invention two, by reading the defeated pattern of multi-antenna transmitting of the idle control information position indication in the base station side utilization control signaling, realized under the situation that does not increase the control information position, make things convenient for the defeated pattern of subscriber equipment identification multi-antenna transmitting, effectively saved the signaling transfer resource, realized simple and convenient.
The embodiment of the invention three provides a kind of sending method of controlling signaling, and as shown in Figure 3, the transmission application scenarios of the described control signaling of present embodiment is as follows: a kind of control signaling both can indicate multi-antenna multiplexed pattern also can indicate the multi-antenna diversity pattern.This method comprises the steps:
Step 301: the defeated pattern of the multi-antenna transmitting that the transmission of base station side specified data is used is the multi-antenna diversity pattern.
Above-mentioned base station side can refer to one or more base stations, and therefore, the method that the embodiment of the invention provides is both applicable to single cell scenario, also applicable to many cell scenario.
Step 302: above-mentioned base station side is utilized the idle control information position indication multi-antenna diversity pattern in the control signaling of above-mentioned transfer of data correspondence, wherein, this control information position is the information bit of information one of being used to indicate at least under the multi-antenna multiplexed pattern below free time: order, pilot tone port and scrambler identify.
Under the above-mentioned multi-antenna diversity pattern, can use CRS (cell-specific pilot tone, Cell-specificReference Signal), also can use DMRS as demodulation pilot frequency as demodulation pilot frequency.The port of employed CRS or DMRS can be made an appointment by base station side and UE side under the multi-antenna diversity pattern, or communicates by letter with the UE side by base station side and to make both sides know altogether.So, under the multi-antenna diversity pattern, can not send the port controlling information of CRS or DMRS.In described multi-antenna diversity pattern, the number of data layers of transmission is fixed as 1, so, under the multi-antenna diversity pattern, the not number of plies of notification data, i.e. order; The SCID that multi-antenna diversity uses (Scrambling Identity, scrambler sign) can be predesignated by base station side and UE side, or communicates by letter with the UE side by base station side and to make both sides know altogether.So, under the multi-antenna diversity pattern, can not notify SCID.
Therefore, under the above-mentioned multi-antenna diversity pattern, can with indication order, pilot tone port and (or) the information bit indication multi-antenna diversity pattern of scrambler sign.
For example: under the above-mentioned multi-antenna diversity pattern, DMRS port indication information position becomes the idle condition position.Give designated value with the DMRS port indication information position of described free time, indication current multi-antenna transmission mode is a multi-antenna diversity.Above-mentioned designated value can be made an appointment for base station side and UE side, or the value that is used to indicate the multi-antenna diversity pattern of communicating by letter both sides are known altogether with the UE side by base station side.Under the multi-antenna multiplexed pattern, DMRS port information indicating bit still can be used to indicate base station side to determine the DMRS port information that uses.That is, if the value of DMRS port information indicating bit is not above-mentioned designated value, then the defeated pattern of multi-antenna transmitting this moment is multi-antenna multiplexed pattern.
In like manner as can be known, also can use the information bit of above-mentioned indication order or scrambler sign separately, the current defeated pattern of multi-antenna transmitting of indication under the multi-antenna diversity pattern, the indicating mode of method and above-mentioned use DMRS port information indicating bit is roughly the same, does not repeat them here.
Again for example: under the above-mentioned multi-antenna diversity pattern, DMRS port and order information joint instructions information bit become idle control information position.Above-mentioned joint instructions information bit refers to the one group of information bit that can indicate DMRS port and order information simultaneously.Should the free time control information position give designated value, indication current multi-antenna transmission mode is a multi-antenna diversity.Described designated value can be predesignated for base station side and UE side, or the value of knowing altogether by base station side and UE side communicating pair.Under the described multi-antenna multiplexed pattern, DMRS port and order information joint instructions position still indicate base station side to determine DMRS port information and the order information of using.That is, the value of DMRS port and order information joint instructions position is not above-mentioned designated value, and then the defeated pattern of multi-antenna transmitting this moment is multi-antenna multiplexed pattern.With form one is example, and form one can be applied in 8 antennas, uses DMRS port and order information joint instructions position indication multi-antenna diversity pattern.In the control signaling, the storage of DMRS port and order information joint instructions position be sequence number in the form, from table, as can be known, known sequence number, can know order information and DMRS port information that it is corresponding.When a data transmission block enables, use the left side form, when two data transmission blocks enable, use the right-hand part form.When the defeated pattern of definite multi-antenna transmitting is multi-antenna diversity, have only a data transmission block to enable, its DMRS port and order information joint instructions position can corresponding left side forms.Under the multi-antenna diversity pattern,, do not need to indicate the DMRS port information if use CRS as pilot tone; If use DMRS as pilot tone, the port information of DMRS can be predesignated by base station side and UE side, or communicates by letter with the UE side by base station side and to make both sides know altogether.Under the multi-antenna diversity pattern, order (number of data layers) always is 1, does not need indication.So, DMRS port and order information joint instructions position free time.According to form 1, base station side and UE side agreement sequence number 5 indication multi-antenna diversities.That is, when the value of DMRS port and order information joint instructions position is 5, represent that the defeated pattern of multi-antenna transmitting of current control signaling indication is a multi-antenna diversity; When the value of DMRS port and order information joint instructions position is not 5, represent that the defeated pattern of multi-antenna transmitting of current control signaling indication is multi-antenna multiplexed.Be understandable that the sequence number that the embodiment of the invention is not limited to DMRS port and order information joint instructions position state form is 5 indication multi-antenna diversity patterns, can indicate the multi-antenna diversity pattern with arbitrary reserved state in 0～7.
Form one
Form two can be applied in 4 antennas, uses DMRS port and order information joint instructions position indication multi-antenna diversity pattern.Indicating means in corresponding 8 antennas of concrete indicating means and above table one is roughly the same, does not repeat them here.
In like manner as can be known, also can use DMRS port and scrambler identification information joint instructions position, perhaps scrambler identifies and order information joint instructions position, the current defeated pattern of multi-antenna transmitting of indication under the multi-antenna diversity pattern, the indicating mode of method and above-mentioned use DMRS port and order information joint instructions position is roughly the same, does not repeat them here.
Form two
Again for example: under the multi-antenna diversity pattern, the joint instructions position of DMRS port, sum of ranks SCID information becomes idle control information position.Above-mentioned joint instructions information bit refers to the one group of information bit that can indicate DMRS port, sum of ranks SCID information simultaneously.Should the free time control information position give designated value, indication current multi-antenna transmission mode is a multi-antenna diversity.Described designated value can be made an appointment for base station side and UE side, or the value of knowing altogether by base station side and UE side communicating pair.Under the described multi-antenna multiplexed pattern, DMRS port, sum of ranks SCID information joint instructions position still indicate base station side to determine DMRS port information, the sum of ranks SCID information of using.That is, the value of DMRS port, sum of ranks SCID information joint instructions position is not above-mentioned designated value, and then the defeated pattern of multi-antenna transmitting this moment is multi-antenna multiplexed pattern.With form three is example, and form three can be applied in 8 antennas, uses DMRS port, sum of ranks SCID information joint instructions position indication multi-antenna diversity pattern.In the control signaling, the storage of DMRS port, sum of ranks SCID information joint instructions position be sequence number in the form, from table, as can be known, known sequence number, can know its corresponding DMRS port, sum of ranks SCID information.When a data transmission block enables, use the left side form, when two data transmission blocks enable, use the right-hand part form.When the defeated pattern of definite multi-antenna transmitting is multi-antenna diversity, have only a data transmission block to enable, its DMRS port, sum of ranks SCID information joint instructions position can corresponding left side form.Under the multi-antenna diversity pattern,, do not need to indicate the DMRS port information if use CRS as pilot tone; If use DMRS as pilot tone, the port information of DMRS can be made an appointment by base station side and UE side, or communicates by letter with the UE side by base station side and to make both sides know altogether.SCID information can be predesignated by base station side and UE side, or communicates by letter with the UE side by base station side and to make both sides know altogether.Under the multi-antenna diversity pattern, order (number of data layers) always is 1, does not need indication.So, DMRS port, sum of ranks SCID information joint instructions position free time.According to form 1, base station side and UE side agreement sequence number 8 indication multi-antenna diversities.That is, when the value of DMRS port, sum of ranks SCID information joint instructions position is 8, represent that the defeated pattern of multi-antenna transmitting of current control signaling indication is a multi-antenna diversity; When the value of DMRS port, sum of ranks SCID information joint instructions position is not 8, represent that the defeated pattern of multi-antenna transmitting of current control signaling indication is multi-antenna multiplexed.Be understandable that the sequence number that the embodiment of the invention is not limited to the state form of DMRS port, sum of ranks SCID information joint instructions position is at 8 o'clock, indication multi-antenna diversity pattern can be indicated the multi-antenna diversity pattern with arbitrary reserved state in 0～15.
Form three
Form four can be applied in 4 antennas, uses DMRS port, sum of ranks SCID information joint instructions position indication multi-antenna diversity pattern.Indicating means in corresponding 8 antennas of concrete indicating means and above table three is roughly the same, does not repeat them here.
Form four
Step 303: the control signaling that sends above-mentioned transfer of data correspondence to UE.
The method that is provided according to the embodiment of the invention three, by the indicated information in part control information position is informed subscriber equipment by alternate manner, and utilize the above-mentioned part control information position indication multi-antenna transmitting that frees out to fail pattern, realized under the situation that does not increase the control information position, order control signaling can indicate multi-antenna transmitting to fail pattern, therefore the embodiment of the invention need not increase new signaling consumption, has effectively saved the signaling transfer resource, realizes simple and convenient.
The embodiment of the invention four provides a kind of method of reseptance of controlling signaling, and its application scenarios is identical with embodiment three applied scenes, can be used in to receive that the base station sends control signaling among the embodiment three.As shown in Figure 4, this method may further comprise the steps:
The control signaling of the transfer of data correspondence that step 401:UE reception base station side issues.
Step 402: above-mentioned UE determines that according to the idle control information position in the described control signaling the defeated pattern of multi-antenna transmitting that above-mentioned transfer of data is used is the multi-antenna diversity pattern, wherein, above-mentioned idle control information position is the information bit of information one of being used to indicate at least under the above-mentioned multi-antenna multiplexed pattern below: order, pilot tone port and scrambler identify.
The specific explanations and the recognition methods of above-mentioned idle control information position can be described with reference to the step 302 in the inventive embodiments three, repeat no more, thereby UE can be known the defeated pattern of multi-antenna transmitting that above-mentioned transfer of data is used by the value that reads above-mentioned idle control information position.
Step 403:UE carries out data processing according to the multi-antenna diversity pattern of determining.
The method that is provided according to the embodiment of the invention four, by reading the defeated pattern of multi-antenna transmitting that the base station utilizes the idle control information position indication in the control signaling, realized under the situation that does not increase the control information position, make things convenient for the defeated pattern of subscriber equipment identification multi-antenna transmitting, effectively saved the signaling transfer resource, realized simple and convenient.
Be to realize the sending method of the embodiment of the invention one described control signaling, the embodiment of the invention provides a kind of base station, as shown in Figure 5, comprising: determining unit 501, unit 502 and transmitting element 503 are set, wherein:
