Description
Technical field
The present invention relates to the communications field, relate in particular to data method of sending and receiving, data sending terminal and data receiver and transmission system.
Background technology
OFDM (Orthogonal Frequency Division Multiple, OFDM) technology is that S3G (comprises LTE (Long Term Evolution, Long Term Evolution), UMB (Ultra-Wideband, super broad band radio communication) etc.) and a kind of physical-layer techniques that adopts among the 4G (16m).The OFDM technology is divided into the narrow-band sub-carriers of some quadratures with the physical layer resources in the wireless communication system in frequency domain, high-speed data-flow is parallel transmission on each subcarrier by string and conversion.Because the narrow-band characteristic of subcarrier can overcome multi-path influence, has eliminated intersymbol interference greatly; Because the orthogonal property of subcarrier, promptly the frequency spectrum between subcarrier is overlapped, thereby has improved the utilance of frequency spectrum.Therefore, in wireless communication system, use the OFDM technology becoming the development trend of mobile communication system, two big mobile communication standards are organized 3GPP (The Third Generation Partnership Project in the world, third generation partner program) and 3GPP2 when proposing the developing direction of follow-on mobile communication, all OFDM as essential technology.Adopting the OFDM technology is a kind of access mode that generally adopts in the future broadband wireless communication systems as multiple access technique, is widely used in LTE (3GPP), and UMB (3GPP2) is in the wireless access systems such as IEEE 802.16e.
HARQ (Hybrid Automatic Repeat Request, mix to retransmit automatically and require) technology retransmits the error-control technique that combines automatically as physical layer forward error correction and link layer, improved spectrum efficiency, improve throughput of system, simultaneously because retransmitting to bring merges gain, so enlarge the coverage of system indirectly.The HARQ basic process is: data receiver is decoded to the data that receive, if can not be correctly decoded, then feeds back to data sending terminal, the request repeat data.The data that data sending terminal sends the last time are repacked transmission by certain processing, carry certain data message and verification redundant information in the packet of repacking, data receiver is after receiving data retransmission, when decoding, in conjunction with the data of data block transmitted and re-transmission last time, make full use of the relevant information that they carry, improve the decoding probability.The use of HARQ technology has improved the error correcting capability of Data Receiving in the Radio Access Network, can adapt to the variation of Radio Link automatically, thereby improves transmission performance, so the HARQ technology is widely used in wireless access system, and for example 802.16e, LTE, UMB etc.For the HARQ technology that is applied in the downlink data transmission, BS (Base Station, the base station) by giving MS (base station in assignment, Mobile Station) transmits data to MS on the downlink resource, MS sends HARQ information to BS at ascending resource, indicate whether correctly to resolve downlink data packet, BS is to retransmit HARQ bag according to the ascending HARQ information decision of MS feedback, still transmits new data packets.So, need be at up design UL HARQ channel, be used for MS feedback HARQ information, in like manner, also need to design DL HARQ channel descending, be used for BS to MS transmission DL HARQ information, respond for the transmitting uplink data of MS.
At up-to-date 3GPP2 UMB[1] in the wireless access system, provide the mechanism of a kind of UL HARQ channel Mapping and transmission.At first, each MS determines the position of UL ack channel for the index position of the downlink data unit of oneself according to assignment.For example on the 5M bandwidth, one has 32 available data transmission units.In UMB, 1 data transmission unit is the time of 16 frequency sub-carrier * 8 OFDM symbol.Time is the minimum data transmission unit of data assignment, i.e. data transmission unit, and portable terminal can be assigned 1 or a plurality of data transmission unit.Each data transmission unit numeral index is 1～32, UL ACK (the Up Line acknowledge that each portable terminal uses, up affirmation) index can be corresponding one by one with the data transmission unit index, the BS data transmission unit 1 of having given the portable terminal assignment for example, the UL ack channel of its correspondence is a UL ack channel 1 so, the portable terminal assignment data transmission unit 5, the UL ack channel of its correspondence is a UL ack channel 5 so.When the portable terminal assignment a plurality of data transmission units, select the UL ack channel of index minimal data transmission unit correspondence, for example assignment data transmission unit 2,3,4, corresponding UL ack channel just is to use UL ack channel 2.By this mapping ruler, each MS is according to the data transmission unit of descending assignment, can the corresponding index that finds definite UL ack channel, and overhead notification that needn't be extra.In UL transfer of data physical frame, BS reserves some resources as UL ACK resource simultaneously, and the unit that has defined the transmission of UL ack channel is tile (piece), and each tile is 8 * 2 time, 8 UL ack channels of carrying in each tile.If the DL of portable terminal assignment (Down Line, descending) data transmission unit is 1, then find the ack channel 1 of first tile, send ACK information in tile the inside, as shown in table 1:
The HARQ channel resource mapping ruler that in the UMB technology, adopts, in fact be exactly by ack channel is divided into groups, each ACK group is by the carrying of predefined basic unit of transfer, and such as being tile based on data transmission unit in UMB, and each ACK group can be carried maximum 8 ack channels.Portable terminal finds corresponding UL ack channel index according to DL data transmission unit index, and sends UL HARQ information.
In realizing process of the invention process, the inventor finds that in the prior art, there are the following problems at least:
In UMB, the position of the up acknowledgement channel of UL ACK (Up Lines Acknowledge) is determined by the data transmission unit of DL (downlines, descending) assignment is unique.When data transmission unit was constant, the position of UL ack channel was just constant, caused at the ack channel of some tile (piece) lining transmission a lot, and the ack channel that transmits in some ti is few.Along with increasing of portable terminal number, code division multiplexing can increase interference, causes defeated decreased performance.For example certain BS assignment data transmission unit (1,2) (3,4,5) 4 portable terminals are given in (6) (7,8), then according to the rule of UMB, these 4 portable terminals all must send the UL ack channel in first t, and other 3 tile are empty, and load is very high in first tile like this, and the ack channel transmission performance descends.Simultaneously, for each portable terminal, as long as the data transmission unit of DL assignment is constant (for example, when resource continuous assignment), UL ACK position is also constant, can cause certain two portable terminal when sending the UL ack channel, in same tile, to send all the time like this, they interfere with each other all the time so, thereby influence their ACK transmission, when a user emission power strong, and another user emission power hour, and then strong transmitting power user will disturb weak transmitting power user all the time, and the ACK that has a strong impact on weak users of power sends performance.Equally, in LTE, also exist two portable terminals to disturb fixing problem.

As shown in Figure 1, a kind of data receive method comprises:
101, portable terminal receives the packet from the current data transmission unit;

Embodiment 2
The embodiment of the invention is an example with portable terminal receives data from the base station scene.
As shown in Figure 2, a kind of data receive method comprises:
201, the channel of transferring ACK information is divided at least two ack channel groups;
In this embodiment, 16 ack channels define 4 tile that transmit the UL ack channels altogether, and as 4 ack channel groups, each ack channel group can be carried any 8 orthogonal codes at most.
202, data transmission unit sequence number and ack channel group sequence number are set up mapping relations.
Wherein, the step of data transmission unit sequence number and ack channel group sequence number being set up mapping relations is: with data transmission unit sequence number input hash function, with the output of Hash function as ack channel group sequence number; For example can be applied among the UMB.
Perhaps, the step that data transmission unit sequence number and ack channel group sequence number are set up mapping relations is: will with the sequence number input hash function of the corresponding control channel transmission unit of data transmission unit, with the output of Hash function as ack channel group sequence number; For example in LTE, for the situation that non-persistent resources is distributed, each BS at first will give the user with resource allocation by resource allocating message, then in the enterprising line data transmission of the resource of assignment.The index of the control channel resource by will sending resource allocating message carries out the HASH computing, and ack channel is evenly distributed in the ack channel group.
Perhaps, the step of data transmission unit sequence number and ack channel group sequence number being set up mapping relations is: perhaps be: will be the sequence number input HASH function of the ack channel of data transmission unit assignment in advance, the output of Hash function is as ack channel group sequence number.For example in LTE, for the situation of persistent resources assignment, BS has clearly distributed the ACK resource index for the user.With the ACK resource of distributing,, be evenly distributed in the ack channel group through the HASH function.
The input of described hash functional operation also comprises: current time information and/or portable terminal ID.
In the present embodiment,, set up mapping relations with ack channel group sequence number for the data transmission unit sequence number is carried out the hash functional operation.
When MS was assigned at least two data transmission units, described data transmission unit sequence number was the sequence number of the data transmission unit of minimum or maximum sequence number.
Wherein, carry in the sequence number of DL data transmission unit is transferred to MS for each MS, current data transmission frame frame number by the BS assignment by BS the data.(the Hash function is a prior art to the hash function, repeat no more herein) have a well discrete effect, so no matter how BS carries out scheduling of resource, can guarantee that all UL ack channels relatively are evenly distributed in the ack channel group, thereby the load that has guaranteed each ack channel group is even, improves the performance that ack channel sends.
The Hash function is a kind of mapping relations, and by a kind of mapping relations, with character string originally, numeral or other key messages are converted to an index value.Be expressed as with relationship: index=function (key).Among this embodiment, the design of Hash function can be adopted general hash algorithm, for example based on hash algorithm or other follow-on hash algorithms of multiplication, DL data transmission unit sequence number and the current data transmission frame frame number of importing is dispersed between 0～3.By the principle of hash algorithm as can be known, as long as the design of hash function is enough good, just the input of hash function can be dispersed between 0～3 more uniformly.After carrying out the hash Function Mapping, DL data transmission unit index corresponding A CK channel group index.In the present embodiment, the input of hash function as shown in table 2 is a DL data transmission unit sequence number, the hash function is output as a discrete integer between 0～3, and for example data transmission unit n is discrete to 1, represents that then MS and tile1 (being ack channel group 1) are mapping relations.
Table 2:
203, data transmission unit sequence number and described orthogonal code are set up corresponding relation, described orthogonal code represents to transmit the correctness of data transmission unit packet.
Wherein, described orthogonal code represents to transmit the correctness of data transmission unit packet.Orthogonal code can have several different definition forms:
First kind is, each data cell is corresponding with an orthogonal code, and orthogonal code represents that packet is by correct receive (ACK);
Second kind is, each data cell is corresponding with an orthogonal code, and orthogonal code is represented incorrect receive (NACK) of packet;
The third is, is respectively 2 orthogonal codes of each data transmission unit definition, and 1 orthogonal code is correctly received ACK corresponding to packet, and another orthogonal code is corresponding to incorrect receive (NACK) of packet.
Among this embodiment, take first kind of orthogonal code definition form.As shown in table 3, data transmission unit 1 corresponding orthogonal code 1, data transmission unit 2 corresponding orthogonal codes 2, by that analogy.Keep orthogonality between the orthogonal code, for example can adopt the walsh sign indicating number.
Table 3:
204, portable terminal receives the packet from the current data transmission unit;
205, portable terminal is selected the ack channel group of current data transmission unit correspondence according to the mapping relations of data transmission unit sequence number and ack channel group sequence number;
In the present embodiment, discrete if BS is assigned data transmission unit 1 to ack channel group 2, then select ack channel group 2; If the BS assignment data transmission unit 3, discrete to ack channel group 1, then select ack channel group 1; If the BS assignment data transmission unit 6,7,8, the data transmission unit 6 of smallest sequence number is discrete to ack channel groups 3, then selects ack channel group 6.As can be seen, the ack channel group at the UL ack channel place of all DL data transmission unit correspondences all is evenly dispersed.
206, portable terminal in the ack channel group of selecting, sends the orthogonal code of current data transmission unit correspondence according to the correctness of the packet that receives the current data transmission unit.
If orthogonal code is first kind of definition form, that is, each data cell is corresponding with an orthogonal code, and orthogonal code represents that packet is by correct receive (ACK).Then this step is: if the packet of current data transmission unit is correctly received, then in the ack channel group of selecting, send the orthogonal code of current data transmission unit correspondence; Otherwise, then do not send orthogonal code.
If orthogonal code is second kind of definition form, that is, each data cell is corresponding with an orthogonal code, and orthogonal code is represented incorrect receive (NACK) of packet.If the packet of current data transmission unit is not correctly received,, send the orthogonal code of current data transmission unit correspondence then in the ack channel group of selecting; Otherwise, then do not send orthogonal code.
If orthogonal code is the third definition form, promptly be respectively 2 orthogonal codes of each data transmission unit definition, an orthogonal code is correctly received ACK corresponding to packet, and another orthogonal code is corresponding to incorrect receive (NACK) of packet.Then whether the packet according to the current data transmission unit is received, and determines that the orthogonal code that sends expression ACK still sends the orthogonal code of representing NACK.
In the present embodiment, orthogonal code is first kind of definition form.As shown in table 4, if BS has been portable terminal assignment data transmission unit 1, when portable terminal when BS correctly receives the packet of current data transmission unit 1, then portable terminal sends orthogonal code 1 to BS on ack channel group 2; If BS has been portable terminal assignment data transmission unit 3, when portable terminal when BS correctly receives the packet of current data transmission unit 3, portable terminal sends corresponding orthogonal code 3 to BS on ack channel group 1; If BS has been portable terminal assignment data transmission unit 6,7,8, when portable terminal correctly receives current data transmission unit 6 from BS, during 7,8 packet, then portable terminal sends orthogonal code 6 corresponding to the current data transmission unit of smallest sequence number to BS on ack channel group 3.

301, the channel of transferring ACK information is divided at least two ack channel groups;
302, with data transmission unit sequence number and current time information and/or portable terminal ID, carry out the hash function, set up mapping relations with ack channel group sequence number.Described current time information can be current data transmission frame frame number.
Wherein, the input of hash function can be data transmission unit sequence number and the temporal information that comprises continuous variation, for example, for example, situation for the assignment of LTE persistent resources, the hash function be input as time dependent current data transmission frame frame number, so each data transmission unit of different time will be mapped to different ACK groups, the mapping relations of setting up are constantly to change, make the discrete results randomization, such two portable terminals can not send ACK information all the time in same ACK group, avoided the problem of phase mutual interference all the time between these two portable terminals, interference randomization in can the ack channel group between the portable terminal has improved the transmission performance of ack channel.
In addition, the input of hash function can also be data transmission unit sequence number and portable terminal ID, makes that the discrete results of HASH function is more even.
Perhaps, the input of hash function can also be data transmission unit sequence number and the temporal information and the portable terminal ID that comprise continuous variation.
In the present embodiment, as shown in table 5, data transmission unit 1 is mapped to ACK group 2, and data transmission unit 3 is mapped to ACK group 1, or the like.
Table 5:
303, according to the ack channel group of data transmission unit mapping and the relative position of ack channel in described ack channel group of data transmission unit correspondence, orthogonal code and data transmission unit are set up corresponding relation.
Among this embodiment, take first kind of orthogonal code definition form, that is, each data cell is corresponding with an orthogonal code, and orthogonal code represents that packet is by correct receive (ACK).If when correctly receiving packet, then send this orthogonal code.Otherwise, then do not send orthogonal code.
In this embodiment, according to the relative position of the ack channel of each data transmission unit correspondence that is mapped to same ACK group, determine the orthogonal code index.As shown in table 6, the relative position of the ack channel of data transmission unit 1 correspondence in ACK group 2 is 1, and be then that data transmission unit 1 is corresponding with orthogonal code 1.The relative position of the ack channel of data transmission unit 2 correspondences in ACK group 2 is 2, and be then that data transmission unit 2 is corresponding with orthogonal code 2.Data transmission unit 14 is mapped to ACK group 2, and the relative position of the ack channel of data transmission unit 14 correspondences in ACK group 2 is 3, and be then that data transmission unit 14 is corresponding with orthogonal code 3.Data transmission unit 16 is mapped to ACK group 2, and the relative position of the ack channel of data transmission unit 16 correspondences in ACK group 2 is 4, and then that data transmission unit 14 is corresponding with orthogonal code 3, other are organized by that analogy.
Table 6:
Implementing all to need a pre-defined orthogonal code corresponding for each data transmission unit in 2, so just needing a lot of sign indicating numbers of definition with one one.Present embodiment 3 has been optimized the definition of orthogonal code, has saved system resource.
304, portable terminal receives the packet from the current data transmission unit;
305, portable terminal is selected the ack channel group of current data transmission unit correspondence according to the mapping relations of data transmission unit sequence number and ack channel group sequence number;
If BS is assigned data transmission unit 1, discrete to ack channel group 2, then select ack channel group 2; If the BS assignment data transmission unit 2, discrete to ack channel group 2, then select ack channel group 2.Other by that analogy.
306, portable terminal in the ack channel group of selecting, sends the orthogonal code of current data transmission unit correspondence according to the correctness of the packet that receives the current data transmission unit.
