Description
Technical field
This disclosure relates to the communications field, in particular to a kind of configuration of signal, sending method and device.
Background technology
In new wireless (the New Radio, NR) of correlation technique, two kinds of transmitted waveforms are supported in uplink, are respectively
DFT-S-OFDM, CP-OFDM.The former is exactly uplink SC-FDMA (the Signal-carrier Frequency- in LTE
Division Multiple Access, single-carrier frequency division multiple access), the latter is exactly Long Term Evolution (Long-Term
Evolution, referred to as LTE) downlink waveform, generally also abbreviation OFDM (Orthogonal Frequency-Division
Multiplexing, Orthogonal Frequency Division Multiplexing) or OFDMA (Orthogonal Frequency-Division Multiple
Access, Orthogonal Frequency Division Multiple Access).DFT-S-OFDM has smaller peak-to-average force ratio, and CP-OFDM has better transmission performance.
In NR, uplink supports two kinds of transmission modes, and a kind of mode is the transmission based on code book (Code Book, CB), separately
A kind of outer mode is to be not based on the transmission of code book.It is referred to as CB based transmission and Non CB based
transmission。
CB based transmission need sending and receiving end to arrange code book.Base station can assign the transmission number of plies r that uses and
Corresponding code word W (i) under the number of plies, if there is Sounding Reference Signal (Sounding Reference Signal, SRS)
Selection, can also indicate the information with reference to detecting pilot frequency instruction (Sounding Reference Indicator, SRI), Fig. 1 is
The schematic diagram of transmission based on code book in disclosure correlation technique.
Terminal can send SRS in which, some resources are selected as upstream data or control in base station in the resource of SRS
The reference of transmission.For CB based transmission, base station also need to further to indicate TRI (number of plies instruction) and
TPMI (Transmitted Precoding Matrix Indicator, precoding instruction) on the basis of SRS precodings again
Carry out precoding and for data or controlling transmission.Here precoding can be used for the selection of port.
Sending and receiving end agreement code book is not required in Non-CB based transmission, and base station can send TRI instruction transmission
Number of plies r can not also be indicated, it is equal with the port number in SRS resource that r is given tacit consent to when not indicating.Terminal is using instruction
SRS resource determine the transmission of data, generally use the precoding mode identical with the SRS of instruction, need not carry out volume
Outer precoding, Fig. 2 are the schematic diagrames for the transmission that the disclosure is not based on code book.
Some terminals may can refer at this time there are multiple panel or the radio frequency beam of the multiple and different aspects of setting
Show multiple SRIs, correspond to the transmission of different antennae group or wave beam respectively.Different SRI can correspond to identical or different transmission
Layer.Multiple SRIs can be indicated in Non-CB based transmission and CB based transmission.
In general, for better transmission performance, dynamically switch over and have apparent gain, switching includes：
Switch between DFT-S-OFDMA and CP-OFDM, switch between CB based transmission and Non-CB based transmission, in difference
SRIs numbers between switch.
But this can significantly increase physical layer control signaling expense, such as：The switching of Waveform needs 1bit.CB
Based, which is transmitted, and Non-CB based transmission switching needs are then outer increases 1bit, and switches between different SRIs numbers, if
2 SRIs of maximum is supported to need 1bit, 4 SRIs of maximum is supported to need 2bit, 8 SRIs of maximum is supported to need 3bit.Physics
Layer signaling consumption is extremely valuable resource, because the robustness requirement of control channel is very high, during general actual transmissions, code check is very
Low, modulation coding scheme is also low order, and the actual transmissions resource of occupancy is very much.If there is substantial amounts of UE, expense waste
It can be very serious.

Embodiment 3
The present embodiment is the alternative embodiment according to the disclosure, and the application is carried out in detail for combining specific embodiment
It describes in detail bright：
In the combined coding technology of the present embodiment, the dynamic of Waveform indication (waveform indication information, WI) is cut
Change owner will reduce expense using following characteristic：
Different code words can be directed to, considers to support different optional Waveform types set respectively.Such as some codes
Word can destroy peak-to-average force ratio, though peak-to-average force ratio can not be controlled using DFT-S-OFDM, therefore will not be in connection
The value condition of different Rank/layer can be directed to, considers the optional Waveform set of types supported respectively
It closes.
Different resource areas can be directed to, considers to support different optional Waveform types set respectively.Using phase
Same waveform can improve uplink MU-MIMO (multi-user's multiple-input, multiple-output, Multiple-User Multiple Input
Multiple Output) performance, therefore resource area can be divided, then corresponding waveform types are set respectively.
Different SRS resource can be directed to, consider to support optional Waveform types set respectively.There are some SRS
Transmission some precodings have been carried out in itself, it is understood that there may be peak-to-average force ratio problem, even if can not be controlled using DFT-S-OFDM
Peak-to-average force ratio processed, therefore will not be in connection
Waveform types set includes " DFT-S-OFDM " " CP-OFDM " " CP-OFDM and DFT-S-OFDM "
Example:RI and PMI instructions and Waveform instruction combined codings are as shown in table 1：
Table 1
Since high Rank situations are typically all the high Cell Center User of signal-to-noise ratio, peak-to-average force ratio problem unobvious, at this time not
DFT-S-OFDM is supported to there will not be apparent performance loss.In addition, in Rank1 code word 05-08 only support CP-OFDM. this
The corresponding precoding of partial codeword can destroy the peak-to-average force ratio of antenna, even if supporting DFT-S-OFDMA that can not have good reduction
Peak-to-average force ratio effect.In above embodiment, can using combined coding as 32 states, can not only be known according to mode bit RI and
PMI information can also know waveform information.By above-mentioned combined coding mode, the more difficult appearance of some actual conditions is avoided
Joint situation can effectively reduce expense.In the present embodiment, absolute coding expense：5bit (RI+PMI)+1bit (WI),
And combined coding expense:5bit(RI+PMI+WI).WI represents waveform indication.
Also some examples are as follows：DFT-S-OFDM and CP-OFDM corresponds to different Rank1 code words and no intersection.
It is contemplated that there is the situation of part intersection.For example code word 01-02 corresponds to two kinds of waveform, code word 03-04 corresponds to DFT-S-
OFDM, code word 05-06 correspond to CP-OFDM, as shown in table 2：
Table 2
| Rank/layer 1 | Rank/layer 2 |
| Code word 01, DFT-S-OFDM | Code word 11, CP-OFDM |
| Code word 02, DFT-S-OFDM | Code word 12, CP-OFDM |
| Code word 03, DFT-S-OFDM | Code word 13, CP-OFDM |
| Code word 04, DFT-S-OFDM | Code word 14, CP-OFDM |
| Code word 05, CP-OFDM | Code word 15, CP-OFDM |
| Code word 06, CP-OFDM | Code word 16, CP-OFDM |
| Code word 07, CP-OFDM | Code word 17, CP-OFDM |
| Code word 08, CP-OFDM | Code word 18, CP-OFDM |
It is as shown in table 3 that Waveform can also carry out combined coding with SRI：
Table 3
| Rank/layer 1 |
| SRI=01, DFT-S-OFDM |
| SRI=02, DFT-S-OFDM |
| SRI=03, CP-OFDM |
| SRI=04, CP-OFDM |
Waveform can also be joined with the instruction combined coding of resource area or with the configuration of DMRS and/or PTRS
It compiles in collaboration with code or carries out combined coding, Power Control instruction parametric joint-coding with MCS.
It should be noted that mode above can be combined, and the mode of specific combined coding also has
The considerations of a variety of other, can be according to specific network environment, the configuration of terminal determines how carry out combined coding.Coding
Bit numbers are also not limited to fixed coding bit numbers.Due to the united situation that will not often occur to some or do not have
The joint situation specific aim needed is limited, and expense can reduce, but actual performance is influenced little.This method can be with
Effectively reduce terminal complexity
Non-CB based are transmitted and CB based transmission switching at runtime mainly reduces expense using following characteristic：
Combined coding is carried out with PMI：
Non-CB based are made into one kind without precoding instruction state.Expression need not use precoding at this time.
The precoding it can be interpreted as the preceding r row of a unit matrix or unit matrix.R is the value of layer/rank, such as 4 institute of table
Show：
Table 4
| Rank/layer 1 | Rank/layer 2 |
| Code word 01 | Code word 11 |
| Code word 02 | Code word 12 |
| Code word 03 | It is indicated without precoding |
| Code word 04 | |
| It is indicated without precoding |
This mode indicates it is which type of transmission without additional 1bit, is not increasing the situation of expense (3bit)
Under, realize dynamic switching.No code word instruction can not also distinguish layer1 or layer2.It is SRS to give tacit consent to layer at this time
Port numbers.
With SRI combined codings
If there is the instruction of SRI, can combined coding be further, as shown in table 5：
Table 5
| SRI=01, CB based |
| SRI=02, CB based |
| SRI=03, Non-CB based |
| SRI=04, Non-CB based |
SRI, TPMI, CB/Non-CB can also be indicated combined coding together, as shown in table 6：
Table 6
| SRI=1 | SRI=2 | SRI=3 | SRI=4 |
| Code word 01 | Code word 01 | Code word 01 | Code word 01 |
| Code word 02 | Code word 02 | Code word 02 | Code word 02 |
| Code word 03 | It is indicated without precoding | Code word 03 | It is indicated without precoding |
| Code word 04 | Code word 04 | ||
| It is indicated without precoding | It is indicated without precoding |
Here have 4bit altogether, and 2+2+1=5bit is needed if absolute coding
With resource indication information combined coding, as shown in table 7：
Table 7
| Resource area 1, CB based |
| Resource area 2, Non-CB based |
So 2bit expenses can be tapered to 1bit.Since resource area 1 is not suitable for doing Non-CB based biographies in itself
It is defeated, any clever loss of energy be practically without.
Can also be with other information combined coding, for example, during CB based TMPI be subband combination.
The switching at runtime of SRI numbers mainly reduces expense using following characteristic：
Combined coding between different SRI numbers, limits the combination of multiple SRI, as shown in table 8：
Table 8
| 1 SIR | 2 SRI | 3 SRI |
| SRI=1 | SRI=1,3 | SRI=1,3,5 |
| SRI=2 | SRI=1,4 | SRI=2,4,6 |
| SRI=3 | SRI=2,3 | |
| SRI=4 | SRI=2,4 |
The SRI=1 that this mode avoids, 2, SRI=3,4, SRI=2,3,5, Isosorbide-5-Nitrae situations such as 6, reduces expense.It is real
On border base station prejudge out disturb in the case of these it is larger it is general be also less likely that this selection can be carried out, so will not
Influence performance.If SRS resource are more, expense saving can become apparent from.
In the implicit indication mode of the present embodiment, Waveform can be indicated using some following modes, including：
DCI format, the demodulation pilot frequency sequence of control channel, the scrambling mode of DCI；The transmission location of DCI.
DCI format corresponding tables 9, the scrambling mode corresponding table 10 of DCI：
Table 9
| DCI Format | Waveform |
| A | DFT-S-OFDM |
| B | CP-OFDM |
Table 10
| DCI scrambles mode | Waveform |
| Scrambler 1 | DFT-S-OFDM |
| Scrambler 2 | CP-OFDM |
It can indicate that Non CB or CB are transmitted using some following modes, including：
DCI format, the demodulation pilot frequency sequence of control channel, the scrambling mode of DCI；The transmission location of DCI, DCI
Format corresponding tables 11, the scrambling mode corresponding table 12 of DCI：
Table 11
| DCI Format | Waveform |
| C | Non CB |
| B | CB |
Table 12
| DCI scrambles mode | Waveform |
| Scrambler 1 | Non CB |
| Scrambler 2 | CB |
The advantageous effect of this embodiment scheme is to have saved expense, the utilization rate higher of signaling consumption.
