Description

Information transmission method and device

technical field

The present invention relates to the technical field of communication, and more specifically, to a method and device for allocating power fiber-to-the-home bandwidth.

Background technique

In a wireless communication system, the transmitting end and the receiving end generally use multiple antennas to transmit and receive to obtain a higher rate. The principle of multi-antenna technology is to use some characteristics of the channel to form multi-layer transmission that matches the characteristics of the channel. The radiation direction of the signal is very targeted, which can effectively improve the system performance and obtain significant performance without increasing the bandwidth and power. Performance enhancement is a very promising technology and is widely used in current systems. During multi-antenna transmission, precoding is generally required to concentrate the signal radiation direction, and the number of precoding layers can be greater than or equal to 1. Compared with common single-antenna transmission technology, multi-antenna reference demodulation will be much more complicated. In traditional single-antenna transmission, it is only necessary to ensure that the time-frequency positions of the data and the reference demodulation pilot are relatively close to each other on the same antenna. For multi-antenna transmission, the pilot and data will go through the precoding process, and it is necessary to ensure that the precoding of the reference demodulation pilot and the precoding of the data are consistent through the physical channel. If the precoding is different, the receiving end can more accurately know the linear relationship between the logical channel (precoding and physical channel) experienced by the reference demodulation pilot and the logical channel experienced by the data. Such notification, which generally requires downlink control signaling, limits flexibility and brings large control signaling overhead.

In the early LTE system, the method used is to perform reference demodulation based on CRS (Cell specific Reference Resource), such as transmission mode 2 (diversity transmission mode), transmission mode 3 (open-loop spatial multiplexing mode), transmission mode 4 ( Closed-loop spatial multiplexing mode), transmission mode 5 (single-layer closed-loop precoding mode), transmission mode 6 (multi-user spatial multiplexing mode), etc., all use CR for reference demodulation, and this demodulation pilot is based on physical The number of ports is generally equal to the number of transmitting antennas, and can support up to 4 ports; this kind of reference demodulation pilot itself does not do precoding, but precoding is required during data transmission, so using this To support MIMO transmission with such a demodulation pilot, the downlink precoding W needs to be notified each time data is sent. Assuming that the CRS passes through the physical channel H, the data will pass through H*W, and the CRS cannot be directly used for data reference demodulation. Since it is necessary to inform W that this method will bring obvious control overhead, and the precoding needs to be selected from the codebook, in order to control the overhead, only the same precoding can be used for the entire bandwidth, which is very inflexible. This design idea was abandoned in the later LTE evolution version, and a new DMRS (Demodulation Reference Signal, demodulation reference signal) was introduced. The new DMRS design idea is to use the same precoding as the data. In this way, the overhead of DMRS can change with the number of layers, and the specific precoding does not need to be notified by additional signaling, just keep consistent with the data. . For the terminal, it is transparent what kind of precoding is used, and the number of ports it sees is generally relatively small, which is much more flexible than the previous method. Wherein, the patterns of the CRS and the DMRS can be shown in FIG. 1 .

In the related art, the downlink precoding used in DMRS-based MIMO transmission in the LTE system has the characteristics of transparency. For terminal demodulation, it only needs to receive and estimate the DMRS port defined on the transmission layer, which can be directly used for demodulation and measurement. The logical channel H*W through which the pilot frequency and data go, does not need to know what kind of precoding W is used on the physical channel H, DMRS and data. The standard complexity is greatly simplified in this way, and the handling of the terminal is also very simple. However, it should be pointed out that the features mentioned above are all based on a basic assumption, that is, to use baseband digital precoding to transmit/baseband to receive. As the number of antennas increases, pure baseband precoding may bring huge costs, so the mixed use of radio frequency precoding and data precoding technologies will be a trend in the future. For a multi-day transmitting and receiving system using mixed precoding of baseband and radio frequency, its mathematical model can be expressed as the following formula:

y＝W _BB W _RF HF _RF F _BB +n

In the above model formula, y is the received wireless signal, and the dimension is the number Nr of the receiving unit RXU; n is interference and noise, and the dimension is also the number Nr of the receiving unit RXU (Receiver Unit, receiving unit); W _BB is The baseband receiving weight of the receiving end, the dimension is related to the number Nr of the receiving unit RXU and the number of layers of the data; W _RF is the receiving weight of the radio frequency receiving end, and the dimension is related to the number Nr of the receiving unit RXU and the number of antenna elements in the receiving antenna group; F _BB is the baseband precoding weight of the transmitting end, and the dimension is related to the number Nt of the transmitting unit TXU (Transmitter Unit, transmitting unit) and the number of data layers; HF _RF is the radio frequency precoding weight of the transmitting end, and the dimension is related to the number Nt of the receiving unit TXU and It is related to the number of antenna elements in the transmitting antenna group.

Since changes in HF _RF and F _BB may cause changes in optimal W _RF and W _BB , additional notification of HF _RF and F _BB information is required. This notification may be based on a preset codebook, codebook The design of the MIMO technology, the overhead of notification signaling, and the reduction of flexibility will all bring very obvious restrictions to the application of MIMO technology.

It can be seen that, for a relatively simple baseband/digital precoding system, the receiving and transmitting radio frequency weights W _RF and HF _RF are all preset fixed values (the weights in the phase array antenna are used to determine the radiation direction of the antenna), Therefore, it is relatively simple to analyze; in the standardization of the communication system, it is enough to focus on how to obtain a more accurate F _BB . The W _BB can be designed by the receiving end. Generally speaking, because the W _BB can be flexibly and dynamically configured in each time domain symbol For a receiving end, the optimal baseband receiving weight is often calculated according to its estimated logical channel (the channel obtained by multiplying the physical channel and precoding, here W _RF HF _RF F _BB ), and then use the The weights are received to obtain good performance. Since the DMRS pilot is also using the same precoding F _BB regardless of the data precoding F _BB used by the sender, the logical channel can always be reflected on the demodulation pilot DMRS, thus transmitting the RF/baseband precoding It can be transparent to the terminal, and there is no need to inform the terminal.

However, when radio frequency precoding is introduced, for radio frequency precoding/reception weights, since it is generally implemented by a phase shifter on the radio frequency, in each time unit, a fixed value needs to be set before receiving the signal , the radio frequency reception weight is aimed at both DMRS pilot and data signals. Compared with the baseband receiving process, it is found that the baseband receiving weights are different from this. The received signal can be buffered first, and then processed after the channel estimation is completed. However, the implementation cost of radio frequency precoding is low, and the signals on each antenna array cannot be buffered for reprocessing. Therefore, there will be a new problem that the receiving end cannot determine the optimal WRF after knowing it. For a system including variable radio frequency precoding, it can no longer have the same transparency and precoding selection as baseband precoding flexibility.

Changes in HF _RF and F _BB may cause changes in the optimal W _RF and W _BB , which requires additional notification of HF _RF and F _BB information. This notification may need to be based on a preset codebook, codebook design , the overhead of notification signaling, and the reduction of flexibility all bring very obvious restrictions to the application of the MIMO technology.

Detailed ways

The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

The downlink precoding used in DMRS-based MIMO transmission in the existing LTE system is very transparent. For terminal demodulation, it only needs to receive and estimate the DMRS port defined on the transmission layer and it can be directly used for demodulation. It is unnecessary to know the precoding W used on the physical channel H, DMRS and data to measure the logical channel H*W of the pilot and data, so this method greatly simplifies the standard complexity, and the terminal processing is also very simple . However, it should be pointed out that the features mentioned above are all based on a basic assumption, which is to use baseband digital precoding to transmit/baseband to receive. As the number of antennas increases, pure baseband precoding may bring huge costs, so the mixed use of radio frequency precoding and data precoding technologies will be a trend in the future. Figure 2 shows the framework of a multi-day transmitting and receiving system using hybrid precoding of baseband and radio frequency.

Among them, for the multi-day transmitting and receiving system using mixed precoding of baseband and radio frequency, its mathematical model can be expressed as the following formula:

y＝W _BB W _RF HF _RF F _BB +n

In the above model formula, y is the received wireless signal, and the dimension is the number Nr of the receiving unit RXU; n is interference and noise, and the dimension is also the number Nr of the receiving unit RXU (Receiver Unit, receiving unit); W _BB is The baseband receiving weight of the receiving end, the dimension is related to the number Nr of the receiving unit RXU and the number of layers of the data; W _RF is the receiving weight of the radio frequency receiving end, and the dimension is related to the number Nr of the receiving unit RXU and the number of antenna elements in the receiving antenna group; F _BB is the baseband precoding weight of the transmitting end, and the dimension is related to the number Nt of the transmitting unit TXU (Transmitter Unit, transmitting unit) and the number of data layers; HF _RF is the radio frequency precoding weight of the transmitting end, and the dimension is related to the number Nt of the receiving unit TXU and It is related to the number of antenna elements in the transmitting antenna group.

Since changes in HF _RF and F _BB may cause changes in optimal W _RF and W _BB , additional notification of HF _RF and F _BB information is required. This notification may be based on a preset codebook, codebook The design of the MIMO technology, the overhead of notification signaling, and the reduction of flexibility will all bring very obvious restrictions to the application of MIMO technology.

It can be seen that, for a relatively simple baseband/digital precoding system, the receiving and transmitting radio frequency weights W _RF and HF _RF are all preset fixed values (the weights in the phase array antenna are used to determine the radiation direction of the antenna), Therefore, it is relatively simple to analyze; in the standardization of the communication system, it is enough to focus on how to obtain a more accurate F _BB . The W _BB can be designed by the receiving end. Generally speaking, because the W _BB can be flexibly and dynamically configured in each time domain symbol For a receiving end, the optimal baseband receiving weight is often calculated according to its estimated logical channel (the channel obtained by multiplying the physical channel and precoding, here W _RF HF _RF F _BB ), and then use the The weights are received to obtain good performance. Since the DMRS pilot is also using the same precoding F _BB regardless of the data precoding F _BB used by the sender, the logical channel can always be reflected on the demodulation pilot DMRS, thus transmitting the RF/baseband precoding It can be transparent to the terminal, and there is no need to inform the terminal.

However, when radio frequency precoding is introduced, for radio frequency precoding/reception weights, since it is generally implemented by a phase shifter on the radio frequency, in each time unit, a fixed value needs to be set before receiving the signal , the radio frequency reception weight is aimed at both DMRS pilot and data signals. Compared with the baseband receiving process, it is found that the baseband receiving weights are different from this. The received signal can be buffered first, and then processed after the channel estimation is completed. However, the implementation cost of radio frequency precoding is low, and the signals on each antenna array cannot be buffered for reprocessing. Therefore, there will be a new problem that the receiving end cannot determine the optimal WRF after knowing it. For a system including variable radio frequency precoding, it can no longer have the same transparency and precoding selection as baseband precoding flexibility.

Changes in HF _RF and F _BB may cause changes in the optimal W _RF and W _BB , which requires additional notification of HF _RF and F _BB information. This notification may need to be based on a preset codebook, codebook design , the overhead of notification signaling, and the reduction of flexibility all bring very obvious restrictions to the application of the MIMO technology.
