A method, performed by the terminal device, for adjusting network configuration, comprising: transmitting (S11, S33), a configuration change request to a base station through a first physical layer resource, the first physical layer resource being a physical layer resource corresponding to a first network configuration parameter, and the first network configuration parameter being a target network configuration parameter requested by the terminal device; receiving (S12, S35), a configuration change response from the base station, the configuration change response indicating whether to employ the first network configuration parameter to adjust a discontinuous reception, DRX, period; and determining (S13, S37) whether to adjust the DRX period based on the configuration change response, wherein determining (S13, S37) whether to adjust the DRX period based on the configuration change response comprises: determining to adjust the DRX period based on the first network configuration parameter when the configuration change response comprises an identifier of the first physical layer resource; or, determining to adjust the DRX period based on a second network configuration parameter corresponding to a second physical layer resource when the configuration change response comprises an identifier of the second physical layer resource; or, determining not to adjust the DRX period when the configuration change response comprises a back off indication. transmitting (S11, S33), a configuration change request to a base station through a first physical layer resource, the first physical layer resource being a physical layer resource corresponding to a first network configuration parameter, and the first network configuration parameter being a target network configuration parameter requested by the terminal device; receiving (S12, S35), a configuration change response from the base station, the configuration change response indicating whether to employ the first network configuration parameter to adjust a discontinuous reception, DRX, period; and determining (S13, S37) whether to adjust the DRX period based on the configuration change response, wherein determining (S13, S37) whether to adjust the DRX period based on the configuration change response comprises: determining to adjust the DRX period based on the first network configuration parameter when the configuration change response comprises an identifier of the first physical layer resource; or, determining to adjust the DRX period based on a second network configuration parameter corresponding to a second physical layer resource when the configuration change response comprises an identifier of the second physical layer resource; or, determining not to adjust the DRX period when the configuration change response comprises a back off indication. determining to adjust the DRX period based on the first network configuration parameter when the configuration change response comprises an identifier of the first physical layer resource; or, determining to adjust the DRX period based on a second network configuration parameter corresponding to a second physical layer resource when the configuration change response comprises an identifier of the second physical layer resource; or, determining not to adjust the DRX period when the configuration change response comprises a back off indication.
