Description

Information processing method, device and system

The present invention relates to communication technologies, and in particular, to an information processing method, apparatus, and system. Background technique

In high-frequency communication, since the transmission is performed with a higher carrier frequency, the average path loss is much larger than that of the conventional Long Term Evolution (LTE) system, for example, using a carrier frequency of 28 GHz. Use the formula:

The calculated average ratio of the high-frequency path loss value to the LTE path loss value is:

Where ^ is the high-frequency path loss value, _£ is 1^£ the road loss value, R is the radius of the cell coverage, and λ _Η is the high-frequency carrier (28 GHz) wavelength, which is the low-frequency carrier (LTE R13 access network carrier) wavelength.

In order to ensure coverage in high-frequency communication, that is, the receiving side satisfies the minimum signal to interference plus noise ratio (SINR) requirement, it is necessary to increase the transmission and receiver gain.

f Λ ²

p = PG G —— = P _t G _t G _r IL _f where R is the radius of the cell coverage, A is the wavelength of the corresponding carrier, is the transmit antenna gain, is the receive antenna gain, is the path loss factor, is the received power, For transmitting power.

The highest demand for LTE communication is required to reach an area covering 100km. If only the average path loss (empty area) is considered according to the highest coverage, the high-frequency communication can be considered to cover an area up to 1km. If considering the high air absorption of the actual high frequency carrier (oxygen absorption, rain fading, fog The fading and sensitivity to shadow fading can actually support coverage less than lkm. If the high-frequency communication supports the maximum lkm coverage, the SINR ratio of the same coverage area can be different compared with the LTE system. The former has a SINR of at least 20 dB lower than the latter, in order to ensure that the high-frequency communication and the LTE system have similar coverage. The SINR needs to ensure the antenna gain of high frequency communication. Since the high-frequency communication has a shorter wavelength, it is possible to accommodate more antenna elements per unit area, and more antenna elements can provide higher antenna gain, thereby ensuring coverage of high-frequency communication.

More antenna elements mean that beamforming can be used to ensure coverage of high frequency communications. According to the previous design idea of LTE, in order to obtain a good beamforming effect, it is necessary to accurately obtain the state information of the channel, thereby obtaining the weight of the beamforming from the state information of the channel. And obtaining a better beamforming weight, for the transmitting base station, the receiving terminal needs to feed back the downlink channel state information or weight. For the receiving end, the transmitting base station needs to feed back the uplink channel state information or the right. The value ensures that the base station can transmit the downlink service by using the optimal beam, and the terminal can also use the optimal beam to meet the specific rule to send the uplink service. At this time, there is a problem: the base station cannot use the optimal beam coverage to the receiving end before obtaining the weight, so that the receiving end cannot measure the reference signal sent by the base station for measurement, or even if the base station covers the terminal, the terminal cannot reach the terminal. The same coverage of the base station, the content of the feedback base station is not known, and thus the selection of beam weights and normal communication cannot be performed.

After the terminal returns the optimal downlink beam index, the base station may use the optimal downlink beam index to select an optimal beam to transmit downlink data to the terminal.

When the terminal needs to send uplink data to the base station, it is also necessary to ensure substantially the same coverage, so that the terminal also needs to use the uplink beam to transmit uplink data, thereby ensuring uplink coverage and reliability transmission on the one hand, and reducing the terminal on the other hand. The average transmit power can save energy for the terminal. Because the terminal does not know the optimal uplink beam to the base station, the uplink beam training process is also required, and the different uplink access signal characteristics used by the terminal are used to identify different uplink beams, and the base station can notify the terminal of the optimal by detecting the signal response. The uplink beam is indexed, so that the terminal can use the optimal uplink beam to send uplink data to the base station. DRAWINGS
