Description
Technical field
Present document relates to but be not limited to wireless communication technique, a kind of espespecially method and device of information feedback.
Background technology
In wireless communication, in the presence of channel reciprocity, terminal need not feed back precoding indication information, only need anti-
Present order instruction and channel quality instruction；And precoding can be utilized by reciprocity based on upstream detection pilot frequency channel detection
The up channel that reference signal measures carrys out the precoding that reciprocity obtains downlink, and this mode is referred to as non-precoded matrix instruction
It feeds back (Non-PMI based feedback), substantial amounts of feedback overhead can be saved, especially for the expense of subband feedback.
Due to terminal there is still a need for calculating order instruction and channel quality instruction, it is desired nonetheless to assume to carry out using a kind of transmission
It calculates.
During 5th Generation Mobile Communication System is eated dishes without rice or wine, when base station sends channel state information reference signals, one is had been carried out
A little precoding processings；In feedback, it may be generally based upon port selection and assume (or being presented as the code word of port selection) to count
Calculate order instruction and channel quality instruction；For example, the channel state information reference signals of 8 ports, using Non-PMI based
Feedback, when transmitting different transport layer (Rank), the corresponding port (port) used is referred to shown in table 1：
| Rank 1 | Rank 2 | …… | Rank 8 |
| Select port i | Select port j, k | …… | Select port 1-8 |
Table 1
In order to obtain enough flexibilities, port i, j, k etc. are that can be configured by base station in 8 ports here
Selection；I.e. base station can configure port, and it is selection to notify which port, which port is confined；For end
Mouth selection and limitation, simple mode include realizing the selection and limitation of port, table 2 by the way of bitmap file (bitmap)
To realize the selection of port and the signal of limitation by the way of bitmap file (bitmap), as shown in table 2：
| Port 1 | Port 2 | Port 3 | Port 4 | Port 5 | Port 6 | Port 7 | Port 8 | |
| Rank 1 | 0 | 0 | 0 | 0 | 1 | 0 | 0 | 0 |
| Rank 2 | 1 | 0 | 0 | 0 | 0 | 0 | 1 | 0 |
| Rank 3 | 1 | 0 | 1 | 0 | 0 | 1 | 0 | 0 |
| Rank 4 | 1 | 1 | 0 | 1 | 0 | 1 | 0 | 0 |
| Rank 5 | 1 | 1 | 1 | 1 | 0 | 0 | 1 | 0 |
| Rank 6 | 1 | 1 | 0 | 1 | 1 | 1 | 0 | 1 |
| Rank 7 | 1 | 1 | 0 | 1 | 1 | 1 | 1 | 1 |
| Rank 8 | 1 | 1 | 1 | 1 | 1 | 1 | 1 | 1 |
Table 2
Table 2 has used 64 bits (bit) to be notified, real although the mode of bitmap seems that comparison is flexible
Border is taken in when having multiple transmission blocks, and how transmission block, which is mapped on transport layer/port, can only use predefined rule；Table 3 is
The signal of predefined rule：
| CW1 | CW2 | |
| Rank 5 | Smaller 3 ports of call number | 2 larger ports of call number |
| Rank 6 | Smaller 3 ports of call number | 3 larger ports of call number |
| Rank 7 | Smaller 4 ports of call number | 3 larger ports of call number |
| Rank 8 | Smaller 4 ports of call number | 8 larger ports of call number |
Table 3
The mode of predefined rule cannot be guaranteed the port (corresponding transport layer) for transmission block being mapped to similar nature, this
Mode is likely to result in same transmission block and is transmitted on the larger port/layer of performance difference, reduces efficiency of transmission.
