Description

Method for updating beam information, terminal device and network device

technical field

The present invention relates to the communication field, in particular to a method for updating beam information, terminal equipment and network equipment.

Background technique

With the increasing demand for data volume of terminal equipment, in order to meet the growing demand for communication performance, the combination of large-scale antennas and high-frequency communication will become a trend, where the high-frequency band is the frequency band above 6GHz.

Specifically, the high frequency band has relatively abundant idle frequency resources, which can provide greater throughput for data transmission. The wavelength of the high-frequency signal is short. Compared with the low-frequency band, more antenna elements can be arranged on the same size panel, which helps to use beamforming technology to form a beam with stronger directivity and narrower lobes, and It provides a high practical prospect for the application of digital-analog hybrid beamforming technology.

For high-frequency communication, with the increase of the working frequency band, the lobes of the simulated beams will be narrower and the number of beams will increase, so it is necessary to increase the measurement delay and increase the reference signal (Reference Signal, RS ) resource overhead. However, the narrower beam will be more sensitive to the movement or rotation of the terminal side, and a small position change will make the transmitting and receiving beams on the network side and the terminal side unable to align, which will cause a decrease in communication quality, which will increase beam training frequency.

Among them, the current existing beam training is controlled by the network side, including periodic beam training and aperiodic beam training. Among them, the aperiodic beam training is dynamically triggered by the network side to measure and optimize beams in a small range. That is to say, the terminal side is not allowed to initiate beam training autonomously. Moreover, the current beam training needs to use Channel State Information Reference Signal (CSI-RS) for downlink beam measurement or Sounding Reference Signal (SRS) for uplink beam measurement , and then the network side indicates the beams of each downlink channel or uplink channel to the terminal side, which takes a long time and is not conducive to fast beam adjustment and data transmission.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

At present, long-term evolution (Long Term Evolution, LTE), enhanced long-term evolution (Long Term Evolution Advanced, LTE-A), fifth generation (5G) and other mobile communication systems have introduced corresponding MIMO (Multiple-Input Multiple- Output, MIMO) technology and Orthogonal Frequency Division Multiplexing (OFDM), to improve the peak rate and system spectrum utilization rate based on the spatial freedom obtained by the multi-antenna system based on MIMO technology.

With the continuous expansion of the dimension of MIMO technology, in LTE Rel-8 version, up to 4 layers of MIMO transmission can be supported, and in Rel-9 version, multi-user MIMO (Multi User MIMO, MU-MIMO) transmission can support up to 4 downlink data layers, and in the Rel-10 version, the transmission capability of Single User MIMO (Single User MIMO, SU-MIMO) is extended to a maximum of 8 data layers. Furthermore, the MIMO technology is being promoted in the direction of three-dimensional and large-scale. At present, the third generation (3G) mobile communication system has completed the research on three-dimensional channel modeling, and is carrying out Enhancements on Full-Dimension MIMO for LTE (eFD-MIMO) and NR (New Radio , new air interface) MIMO research and standardization work. It is foreseeable that in the future 5G mobile communication system, MIMO technology with larger scale and more antenna ports will be introduced.

In addition, massive antenna technology (Massive MIMO) uses large-scale antenna arrays, which can greatly improve the efficiency of system frequency band utilization and support a larger number of access users. Therefore, massive antenna technology is the most promising technology in the next generation of mobile communication systems. One of the physical layer technologies. In large-scale antenna technology, if an all-digital array is used, the maximum spatial resolution and optimal MU-MIMO performance can be achieved, but this structure requires a lot of analog-to-digital signal conversion (Analog to Digital Convert, AD)/ Digital-to-analog signal conversion (Digital to Analog Convert, DA) conversion devices and a large number of complete RF-baseband processing channels will be a huge burden both in terms of equipment cost and baseband processing complexity.

In order to avoid the above-mentioned implementation cost and equipment complexity, digital-analog hybrid beamforming technology is applied, that is, on the basis of traditional digital domain beamforming, a level of beamforming is added to the RF signal near the front end of the antenna system . Analog shaping can achieve a rough match between the transmitted signal and the channel in a relatively simple way. The dimension of the equivalent channel formed after analog shaping is smaller than the actual number of antennas, so the subsequent required AD/DA conversion devices, the number of digital channels, and the corresponding baseband processing complexity can be greatly reduced. The residual interference of the analog shaping part can be processed again in the digital domain shaping part, so as to ensure the quality of MU-MIMO transmission. Compared with all-digital beamforming, digital-analog hybrid beamforming is a compromise between performance and complexity, and it has a high practical prospect in systems with large bandwidth in high frequency bands or a large number of antennas.

For the high-frequency band, in the next-generation communication system after the fourth-generation (4G) mobile communication system, the working frequency band supported by the communication system is increased to a high-frequency band above 6GHz, such as 100GHz, and the high-frequency band has relatively abundant idle frequency resources. , which can provide greater throughput for data transmission. At present, 3GPP has completed the high-frequency channel modeling work. The wavelength of the high-frequency signal is short. Compared with the low-frequency band, more antenna elements can be arranged on the same size antenna set, so that the beamforming technology can be used to form the direction. Beams with more robustness and narrower lobes. Therefore, the combination of large-scale antennas and high-frequency communication will become a trend.

However, as the working frequency band increases, such as the frequency band above 50 GHz, the lobes of the simulated beams will become narrower and the number of beams will increase. Therefore, it is necessary to increase the measurement delay and increase the resource overhead of the reference signal RS when performing beam training. However, the narrower beam is more sensitive to the movement or rotation of the terminal device, and a small position change will make the sending and receiving beams of the network device and the terminal device misaligned, which will cause a decrease in communication quality, which will increase beam training. frequency.

Among them, the current existing beam training is controlled by network equipment, including periodic beam training and aperiodic beam training. Among them, aperiodic beam training is for network equipment to dynamically trigger the measurement and beam optimization of small-scale beams. That is to say, the terminal device is not allowed to initiate beam training autonomously. Moreover, the existing beam training needs to use the channel state information reference signal CSI-RS for downlink beam measurement or use the sounding reference signal SRS for uplink beam measurement, and then the network device indicates each downlink channel or uplink channel to the terminal device beam, which takes a long time and is not conducive to fast beam adjustment and data transmission.

Therefore, there is an urgent need for a beam information update scheme to reduce the time-consuming beam information update, achieve fast beam adjustment and data transmission, and further improve communication quality.
