Abstract: Embodiments of the present disclosure disclose a signal transmission apparatus and non-transitory computer-readable storage medium, and relate to the field of communications technologies. The apparatus comprises a memory storing program instructions and a processor coupled to the memory, wherein the program instructions, when executed by the processor, cause the apparatus to obtain configuration information for use to transmit a signal of a second carrier in coverage space of a first carrier, a spectrum occupied by the first carrier and a spectrum occupied by the second carrier overlap, and a subcarrier of the first carrier and a subcarrier of the second carrier are orthogonal; and transmit the signal of the second carrier according to the configuration information.

Abstract: Embodiments of the present disclosure provide a method and an apparatus for downlink and uplink compression of a nonstandard bandwidth of an LTE system. Abase station filters a baseband signal by using a filter whose bandwidth is a nonstandard bandwidth of LTE, and filters out a signal outside the nonstandard bandwidth of LTE; and the base station may send a signal to a terminal by using the nonstandard bandwidth of LTE that can be provided by an operator.

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.

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: Embodiments of the present disclosure disclose a signal transmission apparatus and method, and a wireless access node, and relate to the field of communications technologies, so as to resolve a problem that a spectrum cannot be fully used. The method of the present disclosure includes: obtaining, by a wireless access node, configuration information for use to transmit a signal of a second carrier in coverage space of a first carrier, a spectrum occupied by the first carrier and a spectrum occupied by the second carrier overlap, and a subcarrier of the first carrier and a subcarrier of the second carrier are orthogonal; and transmitting, by the wireless access node, the signal of the second carrier according to the configuration information. The present disclosure is applicable to a scenario in which a signal of a carrier is transmitted in coverage space of another carrier.
