Description
Technical Field
The present invention relates to the field of wireless communications, and in particular, to an information configuration method, an apparatus, a base station, and a terminal.
Background
In a wireless communication system, a multi-antenna technology is an effective means of expanding channel capacity by configuring a plurality of antennas at a transmitting end and a receiving end to transmit streams or match channels to form a power gain. One principle of the multi-antenna technology is to form multi-layer transmission matching channel characteristics by utilizing some characteristics of the channels, so that the radiation direction of signals is very targeted, the system performance can be effectively improved, remarkable performance improvement can be obtained on the basis of not increasing bandwidth and power, and the multi-antenna technology is widely applied to the current system. The quality of data transmission performance of a multi-antenna system is mainly dependent on measurement and feedback of channel information. The measurement and feedback of channel information is therefore the core content of multi-antenna technology; how to guarantee the accuracy of channel measurement and channel information feedback, overhead and robustness become important problems.
Measurement and feedback of channel state information (CSI, channel State Information) is designed to be simpler in early LTE system versions, but as the accuracy requirements are higher and higher, the pilot overhead and feedback overhead and quantization complexity are not expected to increase significantly, so the CSI measurement and feedback technique becomes more and more complex to pursue higher quantization efficiency; in addition, a great number of new designs are introduced due to the need of good adaptability to various different scenes and antenna configurations. The content related to CSI measurement and quantization feedback includes CSI measurement reference signals. Channel state information reference signals (CSI-RS) may be used for measurement of downlink channel information. CSI-RS is divided into two categories: non-precoded pilots (NP CSI-RS), precoded pilots (BFed CSI-RS). For NP CSI-RS, the base station obtains the channel state information by sending pilot frequency at all ports, receiving pilot frequency by the user, measuring and feeding back the channel information. For BFed CSI-RS, the base station configures precoding matrixes for different port groups, loads the CSI-RS on the K sets of CSI-RS resources and sends the CSI-RS on the precoding matrixes (K is more than or equal to 1), and a user measures an equivalent channel and feeds back the CSI on the best CSI-RS resources.
In recent years, with the rise of 5G technology, high-frequency band, large-scale antenna arrays have gained more attention. When the working frequency band is higher, more antennas can be arranged in smaller size space, and proper correlation among the antennas is ensured. Therefore, the high-frequency band enables the arrangement of massive antennas, and the hybrid beamforming manner as shown in fig. 1 becomes a mainstream massive MIMO technology direction in the industry in consideration of the balance between massive MIMO (Multiple-Input Multiple-Output) performance and the complexity of baseband signal processing. In fig. 1, the transmitting end includes N RF Each radio frequency link is connected with M AE An antenna array, on each RF link, RF precoding F by phase modulation RF Analog beamforming, i.e. mapping from baseband ports to antenna elements, is implemented, while baseband precoding F is used over multiple radio frequency links BB Digital beamforming, i.e. mapping from each transport layer to baseband port, is achieved, the final precoding is defined by F RF F BB And (5) determining mixed beam forming. Therefore, for the high-frequency MIMO system, beam training can be performed through multiple CSI-RS resources to obtain appropriate mixed beam information, and the final CSI information such as PMI/RI/CQI or channel matrix is fed back based on the mixed beam information.
For systems using hybrid beamforming, the base station needs to determine the baseband and analog beam information used by sending reference signals and acquiring feedback after the terminal measures the channel. Because the terminal cannot reproduce the analog beam information through baseband processing, the base station needs to configure multiple sets of reference signal resources to acquire the optimal mixed beam forming weight, namely, the beam information can be acquired by adopting the precoding pilot frequency mode.
In the prior art, in a system using hybrid beamforming, because the analog beamforming is applied to the whole bandwidth, when the beam information is acquired, the analog beamforming weight can only be changed in the time domain, and the whole bandwidth is not occupied for the reference signal resource, so that great expenditure is brought.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Example 1
The embodiment of the invention provides an information configuration method, which can comprise the following steps: the base station configures data transmission configuration information on a time unit to the terminal, and sends the data transmission configuration information to the terminal through a physical layer or a higher layer, so that the terminal receives data according to the data transmission configuration information on the time unit, wherein the data transmission configuration information is associated with the configuration information of the measurement reference signal.
Further, in the time unit, the time domain resource of the transmission data is consistent with the time domain resource of the measurement reference signal configuration.
Further, on the time domain resource, the data transmission configuration information includes ratio information of data transmission power and measurement reference signal power.
Further, the measurement reference signal includes at least one of: channel measurement reference signals, interference measurement reference signals, and pre-coded measurement reference signals.
Further, the base station configures a demodulation reference signal to the terminal, where the demodulation reference signal is used for demodulating downlink data, and in the time unit, the demodulation reference signal and the measurement reference signal are configured on the same time domain resource.
Illustratively, the configuration information for transmitting configuration data in fine beam training is described as follows:
in a high frequency communication system, as shown in fig. 1, a precoding gain is obtained by using a hybrid beamforming composed of digital beamforming and analog beamforming to combat high path loss and penetration loss caused by a high frequency channel. Since the range of action of analog beamforming is the entire bandwidth, there is a limit to the allocation of transmission resources when designing the transmission of data and pilot. In particular, when the base station is configured with only one antenna port, the base station can only transmit one beam direction in the entire frequency domain.
As shown in fig. 2, the base station configures pilot resources to acquire beam information. In fig. 2, the horizontal axis T is time, the vertical axis F is frequency, and each cell is a time domain resource. Fig. 2 shows an example of inserting pilots, which may be reference signals for channel, interference or beam measurements, on one orthogonal frequency division multiplexing (OFDM, orthogonal Frequency Division Multiplexing) symbol. On the OFDM symbol, the base station configures an analog beamforming vector, the terminal obtains the gain of the analog beamforming through channel measurement, and in addition, the base station can configure a plurality of digital beamforming matrixes for the OFDM symbol to obtain digital beam information of different sub-bands. Therefore, on this OFDM symbol, transmission of downlink data can be performed at a position where the base station is not configured with pilot.
In the prior art, data transmission is scheduled through a subframe, and if pilot frequency is inserted into the subframe, the base station dynamically informs the terminal of which resources do not accept data through rate matching information. In high frequency systems, however, beam information acquisition by the base station for the terminal may be hierarchical, i.e., the base station has acquired coarse terminal beam information when fine beam acquisition is performed. This coarse beam information may be obtained through initial beam training or may be estimated by a terminal from a previous fine beam training. The layered beam training structure ensures the accuracy and the robustness of the base station to acquire the terminal beam information. Therefore, when the base station acquires the fine wave beam information, the pilot frequency has certain accuracy in the wave beam direction, and therefore, when the base station transmits data on the OFDM symbol by using the same analog wave beam as the pilot frequency, the base station can ensure the accuracy of data transmission to a certain extent. In addition, since the base station does not guarantee that the used analog beam direction is aligned with the terminal on OFDM symbols where the base station does not configure pilots for the terminal on the entire subframe, the terminal does not receive data on these OFDM symbols. Thus, on the pilot-configured subframe, the terminal can receive data only on the pilot-configured OFDM symbol. In this case, the base station may indicate the symbol position of the data transmission without additional signaling, thereby saving signaling overhead. On the other hand, for a subframe where no pilot is configured, the terminal may receive data over the entire subframe when the base station schedules the terminal on this subframe. In addition to the time domain resource locations for data transmission, the base station may increase the performance of data reception or measurement by optimizing the power of data and pilot on the same OFDM symbol when configuring the information for data transmission.
Specifically, when the base station judges that the difference between the data transmission direction and the actual receiving possible direction of the terminal is large, the performance of data receiving can be improved by increasing the power ratio of the data to the pilot frequency on the OFDM symbol; when the base station determines that the difference between the data transmission direction and the possible direction actually received by the terminal is small, the performance of the measurement can be increased by reducing the power ratio of the data to the pilot frequency on the OFDM symbol. In this way, the robustness of data transmission and the performance of beam information acquisition can be ensured according to different scenes and channel conditions.
Since the data and the measurement reference signal may use different digital precoding, in order to demodulate the data, it is also necessary to insert the demodulation reference signal on the OFDM symbol where the data is transmitted for equivalent channel estimation and demodulation of the data. The demodulation reference signal uses the same digital pre-coding as the data and occupies the same time domain resources as the measurement reference signal.
Exemplary, configuration information for configuring data transmission in initial beam training is described as follows:
as shown in fig. 3, the horizontal axis t is time, the vertical axis f is frequency, and the base station performs initial access and acquisition of initial beam information by transmitting a Synchronization Signal (SS), system Information (SI), and beam measurement pilot (BRS) in one period of initial access. The base station first acquires timing information by detecting the SS, and the SS transmits in turn through a plurality of beam directions to ensure coverage, so that the base station can acquire initial information about the terminal beam through the SS in addition to the synchronization timing information. After the timing synchronization is completed, the terminal can acquire configuration information about initial beam training by demodulating SI transmitted from the base station. The base station has some initial information about the beam direction at this time when performing the initial beam training, so that some data transmission can be performed by using this information, i.e. the data transmission and the initial beam training are multiplexed on the same time domain resource. Therefore, the terminal can multiplex data on the corresponding time domain resources by utilizing the beam measurement reference signal configuration information configured by the base station so as to reduce the overhead of initial beam training.
In addition to the time domain resource locations for data transmission, the base station may increase the performance of data reception or beam measurement by optimizing the power of the data and beam measurement reference signals on the same OFDM symbol when configuring the information for data transmission. Specifically, when the base station judges that the difference between the data transmission direction and the actual receiving possible direction of the terminal is large, the power ratio of the data on the OFDM symbol and the beam measurement reference signal can be increased to improve the data receiving performance; when the base station judges that the difference between the data transmission direction and the possible direction actually received by the terminal is small, the measured performance can be increased by reducing the power ratio of the data and the beam measurement reference signal on the OFDM symbol. In this way, the robustness of data transmission and the performance of beam information acquisition can be ensured according to different scenes and channel conditions.
Since the data and the beam measurement reference signals may use different digital precoding, in order to demodulate the data, it is also necessary to insert the demodulation reference signal on the OFDM symbol where the data is transmitted for equivalent channel estimation and demodulation of the data. The demodulation reference signal uses the same digital pre-coding as the data and occupies the same time domain resources as the beam measurement reference signal.
According to the information configuration method provided by the embodiment of the invention, when the data transmission and the pre-coding pilot frequency are multiplexed on the same time domain resource, the limitation and the optimization of the time domain resource occupied by the data transmission requested by the terminal in the terminal group are performed, so that the resource utilization rate is improved, and the overall performance of the data transmission is improved.
Example two
The embodiment of the invention provides an information configuration method, which can comprise the following steps: and the terminal receives data according to the data transmission configuration information on the time unit, wherein the data transmission configuration information is associated with the configuration information of the measurement reference signal.
Further, in the time unit, the time domain resource of the received data is consistent with the time domain resource configured by the measurement reference signal.
Further, on the time domain resource, the data transmission configuration information includes ratio information of data transmission power and measurement reference signal power.
Further, the measurement reference signal includes at least one of: channel measurement reference signals, interference measurement reference signals, and pre-coded measurement reference signals.
Further, the method further comprises: and demodulating downlink data according to the demodulation reference signal configured by the base station, wherein the demodulation reference signal and the measurement reference signal are configured on the same time domain resource in the time unit.
Further, the method further comprises: and if the measurement reference signal is not configured in the time unit, receiving data on all time domain resources in the time unit.
Exemplary, the following describes configuration data transmission configuration information for reception beam training in early fine beam training:
as shown in fig. 4, when the terminal needs to perform the receive beam training to further improve the received signal-to-interference-and-noise ratio, the base station transmits the measurement reference signal in the same beam direction on multiple OFDM symbols so that the terminal can perform measurement in different receiving directions, where in this subframe, the base station may transmit data for the terminal on multiple OFDM symbols, where the OFDM symbols are also located on the same time domain resource as the measurement reference signal. These OFDM symbol positions may be obtained by information in the reference signal configuration about the time domain resource configuration and the number of repetitions. In addition to the time domain resource location of data transmission, when the base station configures the information of data transmission, the base station can increase the performance of data reception or measurement by optimizing the power of data and pilot frequency on a plurality of configured OFDM symbols.
Specifically, when the base station determines that the direction of data transmission and the possible direction actually received by the terminal are greatly different, the performance of data reception can be improved by increasing the power ratio of data to pilot frequency on the OFDM symbols; when the base station determines that the difference between the data transmission direction and the possible direction actually received by the terminal is small, the performance of the measurement can be increased by reducing the power ratio of the data to the pilot on these OFDM symbols. In this way, the robustness of data transmission and the performance of beam information acquisition can be ensured according to different scenes and channel conditions.
Since the data and the measurement reference signals may use different digital precoding, in order to demodulate the data, it is also necessary to insert demodulation reference signals on the OFDM symbols on which the data is transmitted for equivalent channel estimation and demodulation of the data. The demodulation reference signal uses the same digital pre-coding as the data and occupies the same time domain resources as the measurement reference signal.
According to the information configuration method provided by the embodiment of the invention, when the data transmission and the pre-coding pilot frequency are multiplexed on the same time domain resource, the limitation and the optimization of the time domain resource occupied by the data transmission requested by the terminal in the terminal group are performed, so that the resource utilization rate is improved, and the overall performance of the data transmission is improved.
