Specific embodiment

In order to facilitate the understanding of the present invention, it is situated between at this to the subcarrier maps being related in the embodiment of the present invention It continues:

Fig. 1 is the schematic diagram of multi-carrier signal transmission process in the prior art.Referring to Fig. 1, information bit is compiled by channel After code and modulation, grasped by inverse discrete fourier transform (Inverse Discrete Fourier Transform, IDFT) Be mapped in frequency corresponding to subcarrier (hereinafter referred subcarrier maps) formed useful signal, then with demodulation reference Signal (Demodulation Reference Signal, DM RS) merges, and will finally add cyclic prefix (Cyclic Prefix, CP) signal send.Wherein, subcarrier maps process, which that is to say, is placed in signal stream generated accordingly Process (such as i-th of signal is placed in frequency corresponding to k-th of subcarrier and is sent) in frequency corresponding to subcarrier, Due to the characteristic of multi-carrier transmission itself, the signal sent on different sub-carriers is orthogonal, therefore to be sent between each other Signal (signal after modulating as shown in figure 1) is mapped to after each subcarrier, these signals will not interfere between each other. After the receive process of signal then correspond on the contrary, i.e. receiver removes CP, need correspondingly first to isolate DM RS and useful letter Number, channel estimation is carried out further according to the DM RS received, and obtain on corresponding subcarrier according to the corresponding mapping mode of transmitter Signal stream carries out coherent demodulation according to the result of channel estimation, recovers information bit eventually by decoding.If not sending useful Signal and only send the reference signal (Reference Signal, RS) for detection, then transmitter directly generates RS and adds CP is retransmited, and which is not described herein again.

The signal that the network equipment or UE are received be have different frequency waveform and direct current (Direct Current, DC) the superposition of level, since the energy of DC level is very high, if sending useful signal using the corresponding frequency of DC level It is very big by the interference of DC level to make useful signal, therefore it is useful to transmit to be often used without the corresponding frequency of DC level Signal, the frequency are exactly the most intermediate frequency (hereinafter referred to as DC frequency) of system bandwidth.Also, in order to avoid direct current as far as possible The flat influence to other signals, can be used for transmitting useful signal, subcarrier closest to DC frequency frequency should be with DC frequency Rate is big as far as possible.

In LTE system, the subcarrier maps mode of downstream transmission is different, since in uplink, UE is sent out The number of delivering letters is limited to the requirement that peak-to-average power ratio (Peak-to-Average Power Ratio, PAPR) cannot be too high, and UE is used The multi-access mode of SC-FDMA sends uplink signal and signal requires continuously in frequency domain, i.e., signal must be mapped in frequency Upper continuous subcarrier.In downlink transfer, the network equipment sends signal and is not limited by PAPR, then using the more of OFDMA Location mode sends downlink signal, and signal is not required for certain continuous in frequency domain.

Fig. 2 is a kind of subcarrier maps schematic diagram of the downstream transmission provided in the embodiment of the present invention, referring to fig. 2, The most intermediate frequency (DC frequency) of middle system bandwidth is f_0 (unit Hz), and subcarrier spacing is Δ f；For uplink, sub- load The frequency of wave is respectively ± 1/2 ± 3/2 ± 5/2 Δ f of Δ f, f_0 of Δ f, f_0 of f_0 ...；For downlink, the frequency point of subcarrier Not Wei ± 2 ± 3 Δ f of Δ f, f_0 of f_0 ± Δ f, f_0 ....It that is to say, the mapping mode of uplink sub-carrier makes all sub- loads The frequency of wave and the most intermediate frequency of system bandwidth are at least separated by 1/2 subcarrier width, and the mapping side of downlink sub-carrier Formula makes the frequency of all subcarriers and the most intermediate frequency of system bandwidth be separated by least one subcarrier width, wherein downlink The signal of transmission avoids DC frequency.In this way, the mapping mode of uplink sub-carrier and the mapping mode of downlink sub-carrier there is Half subcarrier staggeredly, the frequency that they are mapped to is different.Since the subcarrier maps mode of uplink and downlink is different, so that There is dislocation (or there are frequency deviations) in the frequency of the subcarrier of uplink and downlink, and make the frequency of subcarrier different, if also resulting in When sending uplink and downlink signals using identical frequency range simultaneously, the inter-carrier interference between uplink and downlink signals is serious, receiving device without Method distinguishes uplink signal and downlink signal.

It should be understood that for (Frequency Division Duplex, FDD) system duplexing for conventional frequency division, uplink and The system bandwidth of downlink signal is different, and the f_0 of uplink signal indicates the most intermediate frequency of up-link bandwidth, downlink letter Number f_0 indicate downlink system bandwidth most intermediate frequency；Duplexing for traditional time division (Time Division Duplex, TDD) for system, the system bandwidth of uplink and downlink signal is identical.

The present invention is suitable for any wireless communication system, particularly, it is logical to be suitable for flexibly duplexing (Flexible Duplex) In letter system, it is related to the different up-downlink directions of corresponding time-varying such as service adaptation, interference adaptation, resource adaptation or the hair of duplex It penetrates, reception device, i.e., the variation for situations such as involved device can be with business, disturbed condition and the utilization of resources correspondingly changes Become the distribution of uplink and downlink resource, wherein uplink and downlink resource includes time and/or frequency resource.

To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention Formula is described in further detail.

Fig. 3 is a kind of method flow diagram of the wireless transmission provided in the embodiment of the present invention, referring to Fig. 3, this method comprises:

301: first network equipment sends downlink signal in the first running time-frequency resource, and first running time-frequency resource is the first UE In the running time-frequency resource for wherein sending uplink signal, carries subcarrier included by the first running time-frequency resource of the downlink signal and hold It carries subcarrier included by the first running time-frequency resource of the uplink signal and corresponds to identical frequency；

At least one signal includes useful signal in the downlink signal and the uplink signal, and the uplink signal and The corresponding resource unit of reference signal included by either signal in downlink signal (Resource Element, RE) and another The corresponding resource unit of useful signal in signal is not overlapped, and wherein running time-frequency resource includes multiple resource units, each resource list One symbol of the corresponding time domain of member and a subcarrier of frequency domain.

The step 301 specifically includes: first network equipment will need the signal sent to be mapped on the first running time-frequency resource, Downlink signal is sent in first running time-frequency resource.Correspondingly, while first network equipment sends downlink signal, the first UE need to The signal to be sent is mapped in the first running time-frequency resource, sends uplink signal in the first running time-frequency resource.

Preferably, the first running time-frequency resource is at least one PRB (Physical Resource Block, Physical Resource Block) To (PRB pair).Correspondingly, first network equipment or the first UE carry out the hair of signal according to one or more PRB pairs of distribution It send or receives.Uplink signal or the minimum particle size of the scheduled transmission of downlink signal are PRB pair, and a PRB pair includes the one of time domain Multiple subcarriers of a subframe and frequency domain.One PRB is to including multiple RE (Resource Element, resource unit), each Resource unit corresponds to a symbol of time domain and a subcarrier of frequency domain；Uplink signal or downlink signal are transmitted in PRB pair, Including transmitting uplink signal or downlink signal on part RE, partial symbols or the whole RE in PRB pair.

Optionally, the first dispatch dispatches multiple network equipments simultaneously or UE carries out receiving or sending for signal, reduces The expense of dispatch.

Preferably, which is the information of PRB pair.Such as, it is 1~3 which, which is number, PRB pair.After first network equipment reads the information, information is sent on the PRB pair that number is 1~3；Second network equipment is read After getting the information, information is received on the PRB pair that number is 1~3.It is 1~3 in number after first UE reads the information PRB pair on send information；After 2nd UE reads the information, information is received on the PRB pair that number is 1~3.

Optionally, in the technical solution based on embodiment illustrated in fig. 3, first dispatch further include: modulating-coding Scheme (Modulation and Coding Scheme, MCS) information, transport layer (Transmission Layer) number information Any one of with reference signal orthogonal resource information.Wherein, Modulation and Coding Scheme information be the network equipment or UE sending or The Modulation and Coding Scheme that uses when receiving signal, such as when Modulation and Coding Scheme information is 10, the network equipment or UE in transmission or The Modulation and Coding Scheme for the use of number being 10 when receiving signal.

When in the first dispatch that first network equipment and second network equipment receive include Modulation and Coding Scheme believe When breath, first network equipment sends information, the second net using corresponding Modulation and Coding Scheme according to the Modulation and Coding Scheme information Network equipment receives information using corresponding Modulation and Coding Scheme according to the Modulation and Coding Scheme information.

When in the first dispatch that the first UE and the 2nd UE are received including Modulation and Coding Scheme information, the first UE root Information is sent using corresponding Modulation and Coding Scheme according to the Modulation and Coding Scheme information, the 2nd UE is according to the Modulation and Coding Scheme Information receives information using corresponding Modulation and Coding Scheme.

Wherein, transmission number of plies information is used to indicate the network equipment or UE when sending or receiving signal, the space used Transmit the number of plies.

Reference signal orthogonal resource information is used to indicate the network equipment or UE when sending or receiving signal, and reference signal makes Orthogonal resource, such as orthogonal code number, frequency range number, when segment number.

Still optionally further, based on the technical solution of embodiment illustrated in fig. 3, different UE or the different network equipments or not The analysis mode of the signaling field for including to first dispatch configured in the equipment of same type is different.First The field for the Modulation and Coding Scheme information for including in dispatch be it is identical, still, identical field is in different UE or not With the network equipment in corresponding coding mode be different or UE and the corresponding coding mode of the network equipment between be also not With, it that is to say for identical first dispatch, different value, the first UE can be understood as between the first UE and the 2nd UE It can be understood as different value between first network equipment, can also be managed between first network equipment and second network equipment Solution is different value.

Such as, when Modulation and Coding Scheme signaling field includes 5 bits, the field is in the dispatch that the network equipment is sent " 01100 ", and when the first UE and the 2nd UE receive same Modulation and Coding Scheme signaling field, then the first UE receives first After dispatch, after reading first dispatch, understand that the corresponding numerical value of Modulation and Coding Scheme signaling field " 01100 " is 12, then the first UE sends signal using the Modulation and Coding Scheme that number is 12；And after the 2nd UE receives the first dispatch, it reads After taking first dispatch, understand that the corresponding numerical value of Modulation and Coding Scheme signaling field " 01100 " is 8, then the 2nd UE is used The Modulation and Coding Scheme that number is 8 receives signal.That is to say, the first UE and the 2nd UE using different MCS signaling fields with MCS value mapping table.First UE sends uplink signal, and the letter between the first UE and first network equipment to first network equipment When road situation is preferable, it is more suitable for sending uplink signal using the Modulation and Coding Scheme of higher order, so that the present invention only passes through one Dispatch is achieved that the first UE and the relevant scheduling of the 2nd UE, reduces signaling overheads, improves efficiency of transmission.

Still optionally further, in the technical solution based on embodiment illustrated in fig. 3, different UE or the different network equipments or What is configured in different types of equipment is used to parse the parsing of the transmission number of plies information or reference signal orthogonal resource information Mode is different.That is to say for identical transmission number of plies information or reference signal orthogonal resource information, the first UE and the 2nd UE it Between can be understood as different value, different value, first network equipment can be understood as between the first UE and first network equipment And second can also be understood as different value between the network equipment.

Still optionally further, in the technical solution based on embodiment illustrated in fig. 3, different UE or the different network equipments or not The analysis mode for parsing the Modulation and Coding Scheme configured in the equipment of same type is different.It that is to say for identical Modulation and Coding Scheme can be understood as different value between the first UE and the 2nd UE, can between the first UE and first network equipment It is understood as different value, different value can also be understood as between first network equipment and second network equipment.

When in the first information that the first UE and the 2nd UE are received including transmission number of plies information, although being wrapped in the first information The field of the transmission number of plies information included be it is identical, still, identical field corresponding value for the first UE and the 2nd UE It is different.

Such as, transmission number of plies signaling field includes 2 bits, and the field is " 01 " in the first dispatch, then the first UE After receiving the first dispatch, after reading first dispatch, understand that transmission number of plies signaling field is " 01 " corresponding number Value is 2, then the first UE is using sending uplink signal by 2 layers of space, and after the 2nd UE receives the first dispatch, reading After taking first dispatch, understand that transmitting number of plies signaling field as " 01 " corresponding numerical value is 3-2=1, then the 2nd UE is used Downlink signal is received by 1 layer of the space in space, i.e. the sum of number of plies of uplink signal and downlink signal is fixed value 3.

When in the first information that the first UE and the 2nd UE are received including reference signal orthogonal resource signaling field, although The reference signal orthogonal resource signaling field for including in the first information be it is identical, still, identical field is in the first UE and Corresponding value is different for two UE.

Such as, orthogonal resource signaling field includes 3 bits, and the field is " 011 " in the first dispatch, then the first UE After receiving the first dispatch, after reading first dispatch, the corresponding numerical value of orthogonal resource signaling field " 011 " is understood It is 3, then the first UE sends uplink DM RS using the orthogonal resource that number is 3, and the 2nd UE receives the first dispatch Afterwards, after reading first dispatch, the corresponding numerical value of orthogonal resource signaling field " 011 " is 12-3=3, then the 2nd UE is used The orthogonal resource that number is 9 receives downlink DM RS, i.e., the sum of number of uplink signal and downlink RS is fixed value 12.

It should be noted that the fixed value in above-mentioned use can be preset in the side UE, can also be sent out from the network equipment to UE The signaling comprising the fixed value is sent, so that UE is after receiving the signalling, obtains fixed value.Preferably, fixed value should be included Signaling is semi-static signaling, and UE only just updates the fixed value when receiving the signaling, continues to make when not receiving the signaling With the old fixed value.

Optionally, in the technical solution based on embodiment illustrated in fig. 3, before the first dispatch of reception, further includes:

The network equipment with Communication Decision ability is to the first UE or the 2nd UE sending deviation value information, the first UE or second UE determines information indicated by signaling field according to the offset value information and the first dispatch.Such as, the network equipment to Before first UE and the 2nd UE sends the first dispatch, sending MCS deviant to the 2nd UE is -4.To the first UE and second MCS signaling field is " 01100 " in the first dispatch that UE is sent, then the first UE is determined according to dispatch using number Uplink signal is sent for 12 MCS, and the 2nd UE then determines that using number be 12- according to MCS offset value information and dispatch The MCS of 4=8 receives downlink signal.

The network equipment with Communication Decision ability to first network equipment or the second network equipment sending deviation value information, First network equipment or second network equipment determine signaling field meaning according to the offset value information and the first dispatch The information shown.Similarly with the side UE, details are not described herein for the principle that the network equipment is sent or received according to offset value information.

It should be noted that the first dispatch is the PDCCH signal in dynamic signaling, such as LTE system, receive every time To the first dispatch only can control the signal transmission of period, and offset value information is semi-static signaling, the network equipment After sending once to UE, until sending the signaling next time, UE uses always the offset value information, the offset value information Transmission not will increase the expense of dynamic signaling, correspondingly, the angle from network equipment side, since the network equipment was receiving one After secondary offset value information, the offset value information is used always, and the transmission of the offset value information not will increase the expense of dynamic signaling.

Still optionally further, in the technical solution based on embodiment illustrated in fig. 3, first dispatch includes the second letter Breath, first dispatch is also used to indicate the first UE or first network equipment reads second information, and described first adjusts Degree signaling is also used to indicate that the 2nd UE or second network equipment ignore second information.Wherein, the second information is uplink signal Or the configuration information of downlink signal.

When the first UE and the 2nd UE receive the first dispatch comprising the second information, appoint in the first UE and the 2nd UE One UE reads the second information in the first dispatch, obtains the uplink signal or downlink signal for including in the first dispatch Configuration information, and another UE then ignores second information.

Still optionally further, in the technical solution based on embodiment illustrated in fig. 3, second information includes power control letter At least one of breath, precoding vector or matrix information.

Wherein, power control information, precoding vector or matrix information are determined for UE and are used when sending uplink signal Signal transmitting power, precoding vector or matrix.

Uplink signal is sent by UE, and what UE obtained that the network equipment sends includes that the network equipment specifies power control information, pre- Second information of coding vector or matrix information, and according to the transmission of the second information progress uplink signal；And downlink signal then by The network equipment is sent, and the network equipment voluntarily determines the power for sending signal and precoding vector or matrix, typically without hair It send and signals UE.In embodiments of the present invention, the first UE reads the signaling field of the second information, according to second information Signaling field sends uplink signal, and the 2nd UE does not read the signaling field then due to being to receive signal.

Still optionally further, in the technical solution based on embodiment illustrated in fig. 3, first dispatch further includes third Information, the third information are used to indicate different UE or the network equipment and send or receive signal using different values.

Preferably, third information can use 2 bit signalling fields, when the first UE and the 2nd UE is got comprising third information The first dispatch after, the first UE read third information, obtain the first attribute information, the first UE read third information, obtain The information of the second attribute is taken, the information of first attribute and the function of the information of the second attribute are different.Such as, the first attribute is used for Triggering UE transmission PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) signal, and second Attribute is then used to trigger UE and sends SRS (Sounding Reference Signal, detection reference signal).

Still optionally further, described before receiving the first dispatch in the technical solution based on embodiment illustrated in fig. 3 Method further include:

First UE or the 2nd UE receives the specific scramble codes information that there is the network equipment of Communication Decision ability to send；

First UE or the 2nd UE receives first dispatch using the specific scramble codes information.

In embodiments of the present invention, the network equipment with Communication Decision ability is according to the specific scramble codes information to described First dispatch is scrambled, and specific is disturbed so that receiving the first UE or the 2nd UE of the specific scramble codes information using described Code information receives first dispatch.

In LTE system, UE can obtain RNTI (Radio Network Temporary in the random access procedure Identifier, radio network temporary identifier) information, is accessed after network, the network equipment is just according to the RNTI information to this The dispatch of UE is scrambled, and be can be and is also possible to the scrambling of signaling bit to CRC (Cyclic Redundancy Code, Cyclic Redundancy Code) bit scrambling, Scrambling Operation can enhance the safety of dispatch bit, and difference UE RNTI information is typically different, to also avoid the dispatch of the other UE of UE garbled-reception.The technology is those skilled in the art Well known to member, the embodiment of the present invention is repeated no more.

In embodiments of the present invention, if UE obtains scheduling letter using the RNTI information obtained in the random access procedure It enables, different UE still correspond to different RNTI, and the network equipment is caused all can not using any one RNTI to scramble dispatch Another UE is set to obtain dispatch.In embodiments of the present invention, after the first UE or the second UE access network, third network is set Standby (network equipment with Communication Decision ability) sends specific scramble codes information, and the first UE or the 2nd UE receive specific scramble codes letter Breath.After the third network equipment scrambles the first dispatch according to specific scramble codes information, the first dispatch is sent, the One UE or the 2nd UE can receive according to specific scramble codes information to the first dispatch.

Still optionally further, based on the technical solution of embodiment illustrated in fig. 3, first dispatch is used to indicate reception To first dispatch sent in the first Transmission Time Interval UE or the network equipment according to first dispatch Send or receive signal in the second Transmission Time Interval, second Transmission Time Interval and first Transmission Time Interval it Between when a length of integral multiple Transmission Time Interval.

In the prior art, if the network equipment sends dispatch scheduling to UE in the Transmission Time Interval TTI that number is n UE transmit uplink signal, can trigger UE number be n+4 TTI send uplink useful signal, the time span of 4 TTI be for UE it is reserved for the time according to the instruction of dispatch to data processing.And for downlink transfer, if the network equipment Dispatch scheduling UE is sent to UE in the TTI that number is n and receives downlink useful signal, then just sends downlink to UE in the TTI Useful signal (network equipment can be in advance dispatch and DSR), therefore uplink and downlink dispatch dispatches UE The time difference of transmission useful signal is different.

In embodiments of the present invention, the first UE and the 2nd UE will receive the first dispatch to send uplink signal or connect Downlink signal is received, in order to make to send uplink signal or receive downlink signal time consistency, the first UE and the 2nd UE are sending and connecing The time difference collected mail number is identical, if that is, the network equipment in the TTI that number is n sends dispatch, the first UE compiling after receiving Number for n+n1 TTI send uplink signal, the 2nd UE receive after then number be n+n1 TTI receive downlink signal.By setting Counting the identical time difference allows the first dispatch to indicate that the first UE and the 2nd UE uses same resource (while with frequency) To send or receive signal.

Still optionally further, in the technical solution based on embodiment illustrated in fig. 3, second Transmission Time Interval with it is described The value of duration between first Transmission Time Interval is identical to being only used for sending the dispatch for scheduling of upstream transmissions The value of Transmission Time Interval and the Transmission Time Interval of uplink.

It is n+n1's in number if the first UE receives the dispatch for scheduling of upstream transmissions in the TTI that number is n TTI sends uplink signal, then the value of the duration between the second Transmission Time Interval and first Transmission Time Interval is n1, In existing LTE system, n1 4, in embodiments of the present invention, it is preferable that n1 4.At the uplink signal of such first UE Reason process can be reused, and reduce system upgrade bring complexity.

Still optionally further, in the technical solution based on embodiment illustrated in fig. 3, if the first UE or the 2nd UE receive first Dispatch and the second dispatch for being only used for dispatching uplink or downlink transfer, instruction UE is between same transmission time When carrying out sending or receiving signal, then ignore the first dispatch.

Wherein, the second dispatch refers to the dispatch in the prior art for being only used for dispatching some one-way transmission.This Invention indicates that the first UE sends uplink signal and indicates that the 2nd UE receives downlink signal by the first dispatch, so that scheduling Signaling utilization rate improves, and is different from traditional dispatch and is only used for indicating that UE is carried out sending operation or received operation.When first UE or the 2nd UE had not only received the first dispatch of the invention, but also received the second traditional dispatch, and the first dispatch UE is indicated with the second dispatch when same Transmission Time Interval carries out sending or receiving signal, then preferentially according to second The instruction of dispatch sends or receives signal, and ignores the instruction of the first dispatch, thus allow the network equipment from The scheduling information that the first dispatch has indicated adaptively is adjusted according to situations such as network load, it is thus also avoided that multiple networks are set It is standby that there are the issuable confounding issues into the scene of UE transmission dispatch ability.Such as the third network equipment has to UE Send the ability of the first dispatch, and first network equipment has the ability that the second dispatch is sent to UE, if then this two A network equipment all sends dispatch to UE, then UE only needs to be sent or received according to one of them.

Optionally, on the basis of the technical solution of embodiment shown in Fig. 3, included by first running time-frequency resource The downlink reference signal is sent in one resource unit, the first resource unit is different from Secondary resource unit, and described second Resource unit is included by first running time-frequency resource, the first UE is for sending resource used in uplink reference signals Unit.First resource unit is different with Secondary resource unit.

Or, the first UE sends the downlink reference signal in the first resource unit of first running time-frequency resource, The first resource unit is different from the Secondary resource unit, and the Secondary resource unit is the first UE for sending Resource unit used in row reference signal.

Optionally, on the basis of the technical solution of embodiment shown in Fig. 3, the first network equipment is in second money Signal is not sent on source unit or the first UE does not send signal on the first resource unit.
