Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of U.S. application Ser. No. 17/436,661, filed Sep. 7, 2021, which is based on PCT filing PCT/CN2020/078119, filed Mar. 6, 2020, which claims the priority to Chinese Patent Application No. 201910193733.4 titled “ELECTRONIC DEVICE, WIRELESS COMMUNICATION METHOD, AND COMPUTER READABLE STORAGE MEDIUM”, filed on Mar. 14, 2019, with the China National Intellectual Property Administration (CNIPA), each of which is incorporated herein by reference in its entirety. FIELD Embodiments of the present disclosure generally relate to the field of wireless communications, and in particular to an electronic device, a wireless communication method, and a computer readable storage medium. Specially, the present disclosure relates to an electronic device for a network side, an electronic device for a user side, a wireless communication method performed by an electronic device for a network side, a wireless communication method performed by an electronic device for a user side, and a computer readable storage medium. BACKGROUND In a process of using an unlicensed frequency band for communication, when a device that is to perform communication accesses to a channel, channel occupancy time for data transmission should be less than Max Channel Occupancy Time (MCOT). In a cellular cell, for example, a network side device of a base station may serve multiple user equipments. In a case of transmitting uplink information, each user equipment is required to perform a channel detection process, to transmit information to the network side device on an idle channel. In this case, time for the user equipment to access to the unlicensed frequency band is greatly increased. In addition, the network side device configures multiple bandwidth parts (BWPs) for each user equipment in frequency domain, and activates one or more of the multiple configured BWPs, so that the user equipment transmits uplink information by selecting one or more of the BWPs that are in an activated state. That is, the user may selects only one of multiple BWPs configured for the user equipment. In this case, frequency domain resources are not fully utilized, resulting in low resource utilization of the system. It is assumed that the user equipment transmits uplink information to the network side device using one BWP that are in the activated state. For some services sensitive to delay, if the user equipment receives no feedback information from the network side device, the user equipment is required to be switched to another BWP that is in the activated state to retransmit the uplink information to the network side device. In this case, the network side device is required to schedule, and the switching process is complex and time-consuming, resulting in not meeting low delay requirements of the services. Therefore, it is required to propose a technical solution to solve at least one of the above technical problems.
