    Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The embodiment of the application provides a method for determining the activation state of a secondary cell and a UE. The method is applied to the technical field of wireless communication and comprises the following steps: acquiring secondary cell activation state indicator information, and then determining respective corresponding states of at least one secondary cell configured or reconfigured by a UE based on the secondary cell activation state indicator information, wherein the states include: an activation state and an inactivation state. The embodiment of the application realizes the reduction of the time delay for the user equipment to receive or send data and the reduction of the time required for deactivating a secondary cell, thereby reducing the power consumption of the UE.

    Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure provides a resource scheduling method, which includes: determining, by a UE, a resource allocation indicating way in DCI of a first type search space and a resource allocation indicating way in DCI of a second type search space, performing, by the UE, blind detection for PDCCH/EPDCCH on the bandwidth and the location of all the frequency resources available for the UE frequency resource allocation in the corresponding resource allocation indicating way according to the allocation unit of the UE frequency resource in the corresponding resource allocation indicating way, determining a bandwidth and a location of an uplink resource and/or a downlink resource actually allocated for the UE.

    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present application relates to the field of radio communication technology, and discloses a random access method, a terminal equipment, and a computer readable storage medium, wherein the random access method includes: receiving configuration information for random access from a base station; determining available first physical random access channel transmission occasions (ROs) according to at least one configured CSI-RS based on the configuration information; and performing random access according to the available first ROs. The method of the embodiment of the present application enables the UE to determine the time-frequency resources for random access by the configured CSI-RS indication.
