Abstract: The present invention relates to the field of communications technologies, and discloses a method for accessing a base station by a terminal, and an apparatus. In this provided solution, after a control base station (CBS) receives an access request message sent by the terminal, the CBS determines, according to received identification information of the terminal and a correspondence between the data base station (DBS) identification (ID) and the identification information of the terminal, a DBS ID that accesses the terminal; then a DBS corresponding to the DBS ID allocates access resource information to the terminal; finally, the terminal accesses the DBS. Therefore, the terminal can also access the DBS even if there is no cell ID in a cell covered by the DBS, thereby avoiding a problem that the terminal cannot access the base station when accessing the base station in a data and signaling separation network.

Abstract: A network device sends downlink control information to a first terminal device. The downlink control information includes: time domain resource information, where the time domain resource is a time domain resource on which a first data channel is located; and frequency domain resource information, where the frequency domain resources are a frequency domain resource on which the first data channel is located and a frequency domain resource on which a second data channel is located. The second data channel is located on a time domain resource different from the time domain resource on which the first data channel is located. The first terminal device receives, on the determined time domain resource and frequency domain resource, a signal that is located on the first data channel and that is from the network device.

Abstract: This application discloses a communication method and an apparatus. A principle of the method is as follows: A spreading factor of a spreading block is adjusted based on available resource elements REs in a time-frequency resource block, then, the spreading block is generated by using the adjusted spreading factor, and finally, the generated spreading block is mapped to the available resource elements in the time-frequency resource block for sending. In this way, a requirement that “locations of spreading blocks of a plurality of users need to be aligned” can be satisfied, and no complex symbol is discarded, so that detection performance of the spreading blocks is ensured.

Abstract: A data transmission method, a terminal, and a network device are provided. In embodiments of the present disclosure, a terminal sends, in a grant-free mode, first data to a network device by using a grant-free resource, and if the terminal needs to switch from the grant-free mode to a grant mode, the terminal sends, in the grant mode, second data to the network device by using a grant resource. When the terminal initially transmits the first data in the grant-free mode, if the terminal needs to switch from the grant-free mode to the grant mode, the terminal may fall back to the grant mode and transmit data in the grant mode.
