Definitions
- the present invention relates to communication technologies, and in particular, to an information processing method, apparatus, and system. Background technique
- 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.
- the calculated average ratio of the high-frequency path loss value to the LTE path loss value is:
- ⁇ is the high-frequency path loss value
- £ is 1 ⁇ £ the road loss value
- R is the radius of the cell coverage
- ⁇ ⁇ is the high-frequency carrier (28 GHz) wavelength, which is the low-frequency carrier (LTE R13 access network carrier) wavelength.
- the receiving side satisfies the minimum signal to interference plus noise ratio (SINR) requirement, it is necessary to increase the transmission and receiver gain.
- SINR signal to interference plus noise ratio
- R the radius of the cell coverage
- A the wavelength of the corresponding carrier
- 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.
- 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.
- the receiving terminal needs to feed back the downlink channel state information or weight.
- 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.
- 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.

Description
一种信息处理方法、 装置和*** 技术领域 Information processing method, device and system
本发明涉及通信技术, 尤其涉及一种信息处理方法、 装置和***。 背景技术 The present invention relates to communication technologies, and in particular, to an information processing method, apparatus, and system. Background technique
在高频通信时, 由于釆用了更高的载波频率进行传输, 那么平均的路 损会比传统的长期演进(Long Term Evolution, LTE ) ***大很多, 例如釆 用 28GHz的载频进行传输, 利用公式:
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:
计算得出高频路损值与 LTE路损值的平均比例信息为:
The calculated average ratio of the high-frequency path loss value to the LTE path loss value is:
其中, ^为高频路损值, £为1^£路损值, R为小区覆盖的半径, λΗ 为高频载波(28GHz ) 波长, 为低频载波 (LTE R13接入网载波)波长。 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.
在高频通信中为了保证覆盖, 即接收侧满足最小信号与干扰加噪声比 ( Signal to Interference plus Noise Ratio, SINR )要求, 需要提高发送和接收 机增益。 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 Λ2 f Λ 2
p = PG G —— = PtGtGr I Lf 其中, R为小区覆盖的半径, A为对应载波的波长, 为发送天线增益, 为接收天线增益, 为路损因子, 为接收功率, 为发送功率。 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.
LTE通信需求最高要求达到覆盖 100km的区域, 如果按照最高覆盖, 仅仅考虑平均路损(空旷区域), 那么高频通信最高可以考虑覆盖达到 1km 的区域。 如果考虑实际高频载波的高空气吸收度(氧气吸收、 雨衰落、 雾
衰落) 以及对于阴影衰落敏感等特点, 实际可以支持的覆盖要小于 lkm。 如果高频通信支持最大 lkm覆盖, 与 LTE***相比, 相同的覆盖区域 可以获得的 SINR比不同, 前者比后者存在至少 20dB的 SINR下降, 为了 保证高频通信与 LTE***覆盖范围内具有近似的 SINR,需要保证高频通信 的天线增益。 由于高频通信具有更短的波长, 从而可以保证单位面积上容 纳更多的天线元素, 更多的天线元素可以提供更高的天线增益, 从而保证 高频通信的覆盖性能。 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.
更多的天线元素意味着可以釆用波束赋型的方法来保证高频通信的覆 盖。 由 LTE先前的设计思想可知, 要想得到好的波束赋型效果需要准确的 获得信道的状态信息, 从而从信道的状态信息中获得波束赋型的权值。 而 获得较好的波束赋型权值, 对于发送端基站来说, 接收端终端需要反馈下 行的信道状态信息或者权值, 对于接收端来说, 发送端基站需要反馈上行 的信道状态信息或者权值, 从而保证基站可以釆用最优的波束发送下行业 务, 终端也可以釆用符合特定规则的最优的波束发送上行业务。 这时就会 存在一个问题: 基站在获得权值前, 无法利用最优的波束覆盖到接收端, 从而接收端无法测量基站发送的参考信号进行测量, 或者即使基站覆盖到 终端, 但是终端无法达到基站的同样的覆盖, 反馈的内容基站无法获知, 从而也不能进行波束权值的选择和正常通信。 发明内容 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.

本发明实施例还提供一种计算机可读存储介质, 所述存储介质包括一 组计算机可执行指令, 所述指令用于执行本发明前述实施例中终端的信息 处理方法。 The embodiment of the present invention further provides a computer readable storage medium, the storage medium comprising a set of computer executable instructions for performing the information processing method of the terminal in the foregoing embodiment of the present invention.
由上可知, 本发明实施例的技术方案包括: 发送多个第一波束, 不同 的所述第一波束携带不同种类的第一发现信号; 接收第二发现信号; 通过 检测收到的各第二发现信号获得符合特定规则的第二发现信号对应的第二 波束。 由此, 基站通过预先发送多个下行波束序列 (利用发现信号承载), 来使得终端可以检测到这种发现信号, 获得下行波束索引并反馈。 终端选 择的下行波束索引是基站到达终端按特定规则获得的最优下行波束对应的 索引, 终端通过反馈所述最优下行波束索引可以保证基站到终端传输数据 的可靠性和最优传输性能。 当终端反馈完所述最优下行波束索引后, 基站 可以利用所述最优下行波束索引选择最优的波束给所述终端传输下行数据。 It can be seen that the technical solution of the embodiment of the present invention includes: sending a plurality of first beams, different first beams carrying different types of first discovery signals; receiving second discovery signals; and detecting each received second The discovery signal obtains a second beam corresponding to the second discovery signal that meets a specific rule. Thus, the base station can detect the discovery signal by obtaining a plurality of downlink beam sequences (using the discovery signal bearer) in advance, and obtain a downlink beam index and feedback. The downlink beam index selected by the terminal is an index corresponding to the optimal downlink beam obtained by the base station to the terminal according to a specific rule, and the terminal can ensure the reliability and the optimal transmission performance of the base station to the terminal by feeding back the optimal downlink beam index. 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.
当终端需要发送上行数据给基站, 同样需要保证基本相同的覆盖, 这 样终端也需要釆用上行波束的方式发送上行数据, 一方面保证了上行链路 的覆盖和可靠性传输, 一方面可以减少终端的平均发送功率, 对于终端可 以起到节能的目的。
因为终端不知道到基站最优的上行波束, 所以同样需要进行上行波束 的训练过程, 终端釆用的不同的上行接入信号特性来标识不同的上行波束, 基站可以通过发现信号响应通知终端最优上行波束索引, 从而终端可以利 用最优的上行波束给基站发送上行数据。 附图说明 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

综上所述, 本发明加入一种发现过程, 通过这个发现过程来使得基站
和终端得以发现对方, 从而利用最优的权值进行通信。 In summary, the present invention incorporates a discovery process by which the base station is caused. And the terminal can discover each other, thereby communicating with the optimal weight.
简单的说发现过程其实就是训练的过程, 发送端通过预先发送多个波 束序列 (发现信号), 来使得接收端可以检测到这种序列, 获得波束序号并 反馈的过程。 终端选择的波束索引是基站到达终端最优波束对应的索引, 终端通过反馈所述索引可以保证基站到终端传输数据的可靠性和最优传输 性能。 当终端反馈完所述波束索引后, 基站可以利用所述波束索引选择最 优的波束给所述终端传输下行数据。 Simply speaking, the discovery process is actually a training process. The sender sends a sequence of multiple beams (discovery signal) in advance, so that the receiver can detect the sequence and obtain the beam sequence number and feedback. The beam index selected by the terminal is an index corresponding to the optimal beam of the base station to the terminal, and the terminal can ensure the reliability and the optimal transmission performance of the data transmitted from the base station to the terminal by feeding back the index. After the terminal returns the beam index, the base station may use the beam index to select the best beam to transmit downlink data to the terminal.
当终端需要发送上行数据给基站, 同样需要保证基本相同的覆盖, 这 样终端也需要釆用波束的方式发送上行数据, 一方面保证了上行链路的覆 盖和可靠性传输, 一方面可以减少终端的平均发送功率, 对于终端可以起 到节能的目的。 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 beam to send the uplink data, which ensures uplink coverage and reliability transmission on the one hand, and reduces the terminal on the other hand. The average transmission power can save energy for the terminal.
因为终端不知道到基站最优的上行波束, 所以同样需要进行上行波束 的训练过程, 终端釆用的不同的上行接入信号特性来标识不同的上行波束, 基站可以通过反馈通知终端最优上行波束索引, 从而终端可以利用最优的 上行波束给基站发送上行数据。 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. The base station can notify the terminal of the optimal uplink beam through feedback. The index, so that the terminal can use the optimal uplink beam to send uplink data to the base station.
