Communication method between base station and user terminal and corresponding devices

Abstract

The invention discloses a communication method between a base station and a user terminal and corresponding devices. The communication method between the base station and the user terminal comprises the following step: user equipment (UE) adopts non-standard bandwidth to communicate with the base station; and before the UE adopts the non-standard bandwidth to communicate with the base station, the method also comprises the following steps: the UE sends an indication which supports the non-standard bandwidth to the base station, and receives the non-standard bandwidth information sent by the base station. By applying the embodiment of the invention, an evolved Node B (eNB) can adopt all or part of the non-standard bandwidth to communicate with the UE which supports the non-standard bandwidth, so as to reduce waste of the bandwidth, improve frequency use ratio and reduce operating cost of the operators.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a communication method and corresponding equipment between a base station and a user terminal. Background technique [0002] A long term evolution (Long Term Evolution, LTE) system supports multiple standard cell bandwidths, and current standard bandwidths include 1.4 megahertz (MHz), 3 MHz, 5 MHz, 10 MHz, 15 MHz and 20 MHz. The evolved base station (evolved Node B, eNB) sends the standard bandwidth information it adopts to the user equipment (User Equipment, UE). Correspondingly, the UE can determine the relevant transmission channel Which part of the standard bandwidth is mapped to the physical resource in the bandwidth. [0003] In the process of realizing the present invention, the inventor found that: at present, the available frequency spectrum obtained by some operators is inconsistent with the standard bandwidth that the LTE system can support. For example, the availa...

[0003] In the process of realizing the present invention, the inventor found that: at present, the available frequency spectrum obtained by some operators is not consistent with the standard bandwidth that the LTE system can support. For example, the available frequency spectrum is 8MHz, which does not meet the standard 10MHz bandwidth, but is consistent with the standard 5MHz Compared with the remaining 3MHz bandwidth, the bandwidth outside the standard bandwidth, such as the 3MHz remaining bandwidth in the above example, will be idle, resulting in a waste of precious spectrum resources
