Description

Communication method and device Technical Field The present application relates to the field of communications, and in particular, to a communication method and apparatus. Background In the field of communication, in order to achieve lower power consumption of a terminal device or a User Equipment (UE), a reception circuit of a circuit includes an MR and an auxiliary circuit (referred to as an auxiliary receiver, an auxiliary link), an auxiliary circuit includes a low power-wake up receiver (LR or LP-WUR, hereinafter simply referred to as LR), and the like. When the MR is in the awake state, the MR receives the transmission of the data (or service), and when the MR is not transmitting the data (or service), the MR enters the sleep state, and if the electronic device has the data to be transmitted, the electronic device sends an awake signal (such as a low power awake signal (low power wake up signal, LP-WUS)) to the auxiliary circuit, such as LR, so that the auxiliary circuit receives the awake signal and wakes the MR to transmit the data. MR includes multiple sleep states, and how to achieve balance between energy saving gain and mobility requirements in different sleep states becomes a problem to be solved. Disclosure of Invention The application provides a communication method and a communication device, which can realize the balance of energy-saving gain and mobility requirements under different sleep states. In a first aspect, the present application provides a communication method, which is applied to a UE side, and which can be performed in case the UE enters an LP-WUS state, as the method is performed by the UE or a first device (e.g. a chip, etc.) in the UE. The method includes the steps that a first device obtains a first configuration, the first configuration comprises at least one of a first measurement relaxation configuration or a second measurement relaxation configuration, in a first sleep state, if a threshold value in the first measurement relaxation configuration is met, measurement relaxation is conducted by using a first measurement relaxation requirement, and in a second sleep state, measurement relaxation is conducted by using a third measurement relaxation requirement if the threshold value in the first measurement relaxation configuration is met. Or the first device acquires a first configuration comprising at least one of a first measurement relaxation configuration or a second measurement relaxation configuration, in a first sleep state, if a threshold in the first measurement relaxation configuration is met, uses a first measurement relaxation requirement to perform measurement relaxation, and in a second sleep state, meets the threshold in the second measurement relaxation configuration, uses a second measurement relaxation requirement to perform measurement relaxation. Wherein the first measured relaxation requirement is higher than the second measured relaxation requirement, and the first measured relaxation requirement is higher than the third measured relaxation requirement. According to the communication method provided by the application, different thresholds can be configured for the first sleep state and the second sleep state, so that the UE can perform measurement relaxation according to different measurement relaxation requirements under the condition of entering different sleep states, and the measurement is performed on a serving cell (hereinafter simply referred to as a cell) or a neighbor cell. The method is equivalent to the measurement relaxation requirement which is more suitable for different sleep states, and the decoupling of the measurement relaxation of the different sleep states is realized. The method can realize a sleep state with large consumption energy, uses looser measurement relaxation requirements (such as measurement relaxation with higher multiples) to carry out cell measurement or neighbor cell measurement, can ensure energy-saving gain, and uses tighter measurement relaxation requirements (such as measurement relaxation with lower multiples) to carry out cell measurement or neighbor cell measurement for the sleep state without too much consumption caused by awakening, so as to effectively ensure the mobility requirements. That is, the communication method provided by the application can realize balance of energy-saving gain and mobility requirement through measurement relaxation of Jie Oudi a sleep state and a second sleep state.
