Abstract

The present application provides a communication method and apparatus. The method comprises: a first device determines wake-up information; the first device modulates the wake-up information to a power domain of a downlink signal in a superimposed manner according to a preset modulation mode; the first device sends the wake-up information so that a secondary communication module of a second device wakes up a primary communication module according to the wake-up information, and establishes a connection with the first device by means of the primary communication module. Because the wake-up information is the information modulated to the power domain of the downlink signal in a superimposed manner, the wake-up information does not occupy independent time-frequency resources. Moreover, since the power consumption of the secondary communication module is less than that of the primary communication module in the second device, lower power consumption reception is achieved by receiving the wake-up information by means of the secondary communication module in the case that the primary communication module is turned off. When there is a downlink service, the secondary communication module wakes up the primary communication module in time, thus avoiding the increase of downlink delay and improving the service quality of the downlink service.

步骤102、第一设备将唤醒信息根据设置的调制方式叠加调制在下行信号的功率域。Step 102: The first device superimposes the wake-up information in a power domain of the downlink signal according to the set modulation mode.

在本实施例中，将唤醒信息根据设置的调制方式叠加调制在下行信号的功率域，即改变或不改变下行信号在一个OFDM符号时间长度内的总功率。In this embodiment, the wake-up information is superimposed and modulated in the power domain of the downlink signal according to the set modulation mode, that is, the total power of the downlink signal within a time length of one OFDM symbol is changed or not changed.

在本实施例中，可以根据实际需要预先设置调制方式对唤醒信息进行调制，将唤醒信息叠加调制在下行信号的功率域。通常情况下，原有的下行信号的每比特的功率均相同，本实施例中，可以将唤醒信息的每比特的功率进行调制，使得唤醒信息的各比特所对应的下行信号在至少一个OFDM符号时间长度内的总功率发生变化，当第二设备的辅通信模块检测到下行信号在至少一个OFDM符号的总功率发生变化时，确定该信号为唤醒信息。例如，若唤醒信息包括多个比特，可以将比特0所对应的下行信号在一个OFDM符号时间长度内的总功率调制为0.9，将比特1所对应的下行信号在一个OFDM符号时间长度内的总功率调制为1。所述的0.9和1是当前下行信号在一个OFDM符号时间长度内的相对功率。In this embodiment, the wake-up information may be modulated by setting a modulation mode in advance according to actual needs, and the wake-up information is superimposed and modulated in a power domain of the downlink signal. Generally, the power of each bit of the original downlink signal is the same. In this embodiment, the power of each bit of the wake-up information can be modulated, so that the downlink signal corresponding to each bit of the wake-up information is at least one OFDM symbol. The total power in the time length changes. When the secondary communication module of the second device detects that the downlink signal changes in the total power of the at least one OFDM symbol, the signal is determined to be wake-up information. For example, if the wake-up information includes multiple bits, the total power of the downlink signal corresponding to bit 0 in a time length of one OFDM symbol may be modulated to 0.9, and the downlink signal corresponding to bit 1 may be in a total length of one OFDM symbol.

For example, the frame length of the LTE downlink signal is 10 ms, and the length of the signal frame of the wake-up information is less than or equal to 10 ms.

可选地，唤醒信息包括至少2个比特，比特0由对应的下行信号在至少一个正交频分复用(orthogonal frequency division multiplexing，OFDM)符号时间长度内的总功率的第一状态或第一状态组合表示，比特1由对应的下行信号在至少一个OFDM符号时间长度内的总功率的第二状态或第二状态组合表示。Optionally, the wake-up information includes at least 2 bits, and the first state or the first of the total power of the corresponding downlink signal in the at least one orthogonal frequency division multiplexing (OFDM) symbol time length The combination of states indicates that bit 1 is represented by a second state or a combination of second states of the total power of the corresponding downlink signal over a length of time of at least one OFDM symbol.

在本实施例中，可以利用唤醒信息的每比特的对应的下行信号在OFDM符号的功率变化来表示不同的比特信息，例如，将唤醒信息中的比特0对应的LTE下行信号在至少一个OFDM符号时间长度内的总功率调制为0.9，将唤醒信息中的比特1对应的LTE下行信号在至少一个OFDM符号时间长度内的总功率调制为1，使得唤醒信息不占用独立的时频资源，通常情况下，最多7个OFDM符号的总功率调制1bit唤醒信息。而且，采用多个OFDM符号的总功率调制1bit唤醒信息，可以提高覆盖。In this embodiment, the corresponding downlink signal of each bit of the wake-up information may be used to represent different bit information in the power variation of the OFDM symbol, for example, the LTE downlink signal corresponding to the bit 0 in the wake-up information is at least one OFDM symbol. The total power modulation in the length of time is 0.9, and the total power of the LTE downlink signal corresponding to bit 1 in the wakeup information is modulated to 1 in the time length of at least one OFDM symbol, so that the wakeup information does not occupy independent time-frequency resources, usually Down, the total power of up to 7 OFDM symbols modulates 1 bit wakeup information.
