Contracting, is indicated the data-signal using compression control signal.In one example, the compression control
Signal processed refers to that bit number is less than a kind of control signal of specific type of conventional control signals.Further,
It can be determined whether to use integrated Channel Elements for it according to the size of data of the data-signal.It is big for data
The small data-signal for being no more than the first length, such data-signal are usually between machine and machine
Communication, or the communication between machine and people, integrated Channel Elements can be used to be transmitted.
Fig. 1 is the schematic flow sheet of method for transmitting signals in the embodiment of the present invention.In one example, should
Method 100 includes following operation.
In step 101, compression control signal is generated for the first data-signal.Wherein, first data
Signal is the data-signal of the first user, and the compression control signal is the descending control of first user
Signal.
In one example, the compression control signal is its chi for conventional control signals
It is very little to be less than conventional control signals.In one example, conventional control signals can be normal downlink control
Information (Downlink Control information, DCI) processed, structure is as shown in Figure 2.Specifically,
Conventional DCI includes following 11 fields, is respectively：Multi-carrier indicator 201, resource allocation first 202,
Resource block distributes (RBA) 203, physical uplink control channel (Physical Uplink Control
Channel, PUCCH) on transmitting power control (Transmit Power Control, TPC) order
204, downlink distribution index 205, hybrid automatic repeat-request (Hybrid automatic repeat
Request, HARQ) enter number of passes 206, antenna port 207, transmission block 1 208, transmission block 2 209,
Physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH) RE map and
Accurate co-located designator 210, HARQ-ACK resource compensations 211.At one in the specific implementation, conventional DCI
Length be 52 bits.Wherein, multi-carrier indicator 201, resource allocation be first 202, downlink distribution
Index 205, HARQ enter wherein 1 bit, the transmission block 2 209, and HARQ-ACK of number of passes 206
Resource compensation 211 is optional bit, is shown as oblique line filling in fig. 2.It may be noted that conventional DCI
It is one section of message segment being made up of each field in Fig. 2, transverse axis shows each field in conventional DCI
Put in order, each field includes the bit of specified quantity, for example multi-carrier indicator 201 has 3 ratios
It is special.In the case where control channel unit and Data Channel Unit separate, conventional DCI needs carrying to be used for
Positioning and the information of decoding data signal, cause the size of the conventional DCI larger, wherein especially with resource block
It is more to distribute the bit number that domain takes.It may be noted that compression DCI need not set resource block allocation field
203, therefore its size is smaller.
In one example, when the size of data of first data-signal is no more than the first length, it is
First data-signal generates the compression control signal.
In step 102, integrated channel is constructed for first data-signal and the compression control signal
Unit.
In one example, first length can be the most short long (ratio of bag specified in ICP/IP protocol
Such as 64 bytes, namely 512 bits).When first data-signal is less than or equal to 64 byte,
Compression control signal is generated for it, is transmitted using integrated Channel Elements.In one example, if
Compression control signal and the first data-signal can pass in preceding 7 symbols of a subband (subband)
It is defeated, then using the integrated Channel Elements transmission.In one example, for compression control signal and
The situation that one data-signal can transmit before a subband in 2 or 3 symbols, so that it may use
The integrated Channel Elements transmission.
In step 103, the integrated Channel Elements are provided communicate with carrying the Channel Elements of other signals
It is multiplexed on source, the signal of the integrated Channel Elements is transmitted using the communication resource being assigned to.In an example

Step includes：Modulating-coding strategy (MCS) information is set in the compression control signal, for indicating
The MCS modes that first user uses；Wherein, the MCS information is from complete MCS tables or letter
Change and selected in MCS tables.
In one example, communication system is provided with the MCS modes of multiple ranks, altogether using 5 ratios
Refer in particular to show above-mentioned MCS ranks.In one example, the modulation coding mode that complete MCS tables include
26 grades are shared, corresponds to different order of modulation and channel coding code check from low to high, so as to corresponding different
Spectrum efficiency.For example, low MCS grades use QPSK modulator approaches, and compiled using relatively low channel
Code code check；Medium MCS grades use 16-QAM modulator approaches, and use medium channel coding code
Rate；High MCS grades use 64-QAM modulator approaches, and use higher channel coding code check.For
Control compression DCI length, except indicating complete 26 grades of modulation coding modes using 5 bits
Outside, a subset can also be selected from 26 grades and forms simplified MCS tables.In one example, examine
In the case of considering high reliability, 3 bits can be used to indicate minimum 8 grades in complete MCS tables of MCS
Information, namely simplified MCS tables include minimum 8 grades of MCS information.In one example, it is if simultaneous
, can one MCS mode of every 4 grades of selections, such as selection etc. from 26 grades if caring for reliability and capacity
Level 1,5,9,13,17,21,25, additional highest ranking 26, form a simplified MCS table.
In one example, generate compression control signal for the first data-signal described in step 101 and enter one
Step includes：Compression down link control information (DCI) designator is set in the compression control signal,
For indicating the type of control signal.
In one example, the compression control signal described in Fig. 1 can compress DCI, its form such as table
1 or table 2 shown in.
Table 1
It may be noted that in one example, compression DCI can include signal length and MCS information.
In one example, signal length with the control channel unit (CCE) that takes for base unit.Wherein,
The CCE is one group of time and frequency resource, and the size of this group of running time-frequency resource may be referred to TS36.213's
Definition, it can also provide that the CCE can take how many individual symbols, in frequency in time domain using other definition
Domain can take how many individual subcarriers.In one example, the byte that signal length is included with data-signal
Number is base unit, such as using 16 bytes or 32 bytes as base unit.In one example, institute
Compression DCI is stated to further comprise：HARQ is compensated.In one example, the compression DCI is further

First section content；The verification of generation first domain, for being verified to the correctness of the compression control signal,
And the described first verification domain is arranged on after the compression control signal；First data-signal is set
It is set in the integrated Channel Elements after the described first verification domain.In one example, it is described
First verification domain takes 8 bits.In one example, the first verification of 4 bits can also be set
Domain.In one example, the first verification domain carries out Scrambling Operation using ID (such as RNTI), makes
User can distinguish and be sent to the DCI of oneself.
In one example, not scrambling for 4 bits is first generated using the method for verification sum and verifies domain.Specifically
Ground, all bits of compression control signal are divided into multiple 4 bit groups, if last bit group is not
4 bits of foot are then with 0 polishing, then by the bit of each bit group correspondence position according to nodulo-2 addition criterion
It is added, obtains 4 not scrambling for bit and verify domain.In one example, 8 bit CRC can also be used
Method of calibration generation does not scramble verification domain, and it implements the description referred in TS36.212.
By taking the compression DCI in table 1 as an example, the DCI information of 16 bits can be divided into 44 bit groups,
It is expressed as bn,k(n=0 ..., 3, k=0 ..., 3).Wherein, n is the sequence number of 4 bit groups, and k is some 4 bit group
In the sequence number of each bit that includes.Correspondingly, verification and c can be calculated according to formula (1)k(k=0 ..., 3),
WhereinRepresent nodulo-2 addition.
In one example, the verification domain that do not scramble of 4 bits can be using user's mark (ratio of 16 bits
Such as RNTI) scrambled.Now, the RNTI of 16 bits can be divided into 44 bit groups, so
Afterwards according to formula (2) by the corresponding bit and c in each bit groupkNodulo-2 addition is performed, obtains described the
One verification domain.Wherein, pk(k=0 ..., 3) is the bit included in the first verification domain,
RNTIn,k(n=0 ..., 3, k=0 ..., 3) is the bit in RNTI 44 bit groups, and n is the sequence of bit group
Number, k is the sequence number of each bit in bit group.Similarly, 8 bits do not scramble verification domain can use
The RNTI scramblings of 16 bits, the RNTI are now divided into two 8 bit groups.
In one example, compression control signal can be combined and scrambled with verification domain is not scrambled, now
It is the first verification domain that this, which does not scramble verification domain,.For example, 8 bits in the first verification domain and compression are controlled
Last 8 bit in signal processed forms 16 bit cells, ratio corresponding with the RNTI of 16 bits
Spy carries out nodulo-2 addition.So, last 8 bit of compression control signal and the first verification domain are all by RNTI
Scrambled.
In one example, described in step 102 it is first data-signal and compression control letter
Number constructing integrated Channel Elements further comprises：The verification of generation second domain, for the compression control
Signal, the first verification domain and first data-signal are verified, and verify domain by described second
It is arranged to be located at after first data-signal in the integrated Channel Elements.In one example,
The second verification domain is also scrambled using ID (such as RNTI).
In one example, 24 bit CRC check methods described in TS36.212 can be used to generate
Original checksums domain.In one example, the RNTI of 16 bits can also be used to carry out original checksums domain
Scrambling, generation the second verification domain.Specifically, 16 bits before RNTI and CRC check are entered
The add operation of row mould 2, RNTI rear 8 bit and rear 8 bit of CRC check are then subjected to mould 2 and added
Operation.In this way, the CRC check of 24 bits is all scrambled.It may be noted that in the foregoing description,
Information bit corresponding with the first verification domain, without scrambled processing is not scrambled into verification domain referred to as,
, information bit of without scrambled processing corresponding with the second verification domain is referred to as original checksums domain, with
Show differentiation.
