摘要： Embodiments of this application provide a signal transmission method and apparatus. The method may include: A terminal device receives a first signal from a network device by using a first frequency resource; and in response to the first signal, the terminal device transmits a second signal with the network device by using a second frequency resource. The first frequency resource and the second frequency resource are different frequency domain resources in a system bandwidth, and a subcarrier spacing of the first frequency resource is different from that of the second frequency resource.

摘要： The present disclosure relates to example data transmission methods, user equipment, and access network devices in an LAA-LTE system. An example data receiving method includes determining, by user equipment, first information of a first cell. The user equipment determines a first subframe based on the first information, where a downlink data transmission length of the first subframe is less than a first threshold. The user equipment then determines a data transmission characteristic of the cell in the first subframe based on a preset condition, so as to receive, based on the data transmission characteristic, data including the first subframe. In doing so, a data transmission characteristic of a base station or a terminal is standardized, and a reference signal such as a DRS can be correctly identified.

摘要： Embodiments of the present disclosure provide a data channel sending method. In the method, a base station starts a clear channel assessment (CCA) on a data channel for a to-be-sent data channel. If the CCA on the data channel succeeds, the base station sends the data channel in a first subframe within a time window, where the data channel performs rate matching based on a reference signal (RS). The RS includes a first RS or a second RS. The first RS occupies continuous OFDM symbols in a subframe, and the second RS occupies discontinuous OFDM symbols in a subframe. The time window is a preset time window used to send the first RS, and the first RS is used by a user equipment (UE) to perform cell identification and/or a radio resource management (RRM) measurement on a cell served by the base station.

摘要： A scheduling node sends, in a first TTI to a scheduled node, a scheduling indication of transmitting data by using a preset spectrum resource. After the scheduled node receives the scheduling indication, when it is determined that data can be transmitted in the second TTI according to the scheduling indication, data is transmitted. When the scheduling node determines that the scheduled node can transmit data in the second TTI, it is determined that the data that is transmitted in the second TTI by using the preset spectrum resource is data sent by the scheduled node.

摘要： In response to a user equipment (UE) sending data to a first network side device over a first channel and to a second network side device over a second channel, a method includes determining that the first channel separately overlaps the second channel and a third channel. The method further includes allocating, according to priorities of the first channel and the second channel, a first transmit power to the first subframe j and a second transmit power to the second subframe i. The first transmit power is less than or equal to a first power upper limit. A sum of the first transmit power and the second transmit power is less than or equal to a first threshold. A sum of third transmit power of the third subframe i+1 and the first power upper limit is less than or equal to a preset threshold.
