Abstract: The present disclosure relates to spectrum resource allocation methods. One example method includes a base station obtains, in real time, a network access request message from a terminal, where the network access request message includes at least one of a network standard supported by the terminal, an access service of the terminal, or QoS of the access service, the base station dynamically allocates spectrum resources to different network standards based on the network access request message, and the base station sends a first network standard access indication message to the terminal, where the terminal accesses a service based on the first network standard access indication message via a corresponding network standard.

Abstract: A channel estimation method, a related device, and a system are described. A method for channel estimation may include determining when there is a damaged cell measurement reference signal (CRS) in a plurality of CRSs in target resource blocks (RBs), where the target RBs are RBs in compressed standard bandwidth. The method may also include performing, by a terminal, channel estimation by using an undamaged CRS instead of the damaged CRS in the plurality of CRSs. Based on the method, accuracy of channel estimation can be improved, and a problem of a relatively large error of a demodulation result of a data demodulation service performed based on the channel estimation result is resolved.
