摘要： A method and an apparatus for requesting system information, user equipment and a base station are disclosed by the present disclosure. The method includes: sending a first random access request, where the first random access request carries at least one pilot code for identifying to-be-requested SI; monitoring a response message corresponding to the first random access request within a preset time period, where the response message carries information for responding to the pilot code; and when the response message is detected, based on a pilot code identifier included in the response message, monitoring and receiving the to-be-requested SI within a transmission window of to-be-requested SI corresponding to the pilot code identifier. The technical solutions of the present disclosure can avoid a problem of long latency for the UE to obtain the SI, which is caused by the failure of the UE requesting the to-be-requested SI through the random access request so that the base station cannot broadcast the second type of SI in time.

摘要： Disclosed is a state switching method, a state keeping method and devices. According to the method, when User Equipment, UE (120), is in an inactive state and meets a first predetermined condition, the UE (120) is switched from the inactive state to an idle state (502). When the UE (120) is in the inactive state and meets a second predetermined condition, the UE is kept in the inactive state (503). When the UE (120) is in the inactive state and meets a third predetermined condition, the UE (120) is switched from the inactive state to a connect state (504). The inactive state is an intermediate state between the connect state and the idle state.

摘要： Disclosed in the embodiments of the present application are a processing method and apparatus for rollback from small data transmission (SDT) to non-SDT, which can be applied to cellular mobile communication technology. The method comprises: during an SDT process of a terminal device, when it is determined that a designated trigger condition is satisfied, performing rollback from the SDT process to a non-SDT process. Therefore, a terminal device can perform rollback from an SDT process to a non-SDT process before the SDT process is completed, such that the terminal device performs data transmission on the basis of the non-SDT

摘要： Disclosed in the embodiments of the present disclosure are a data reception processing method and apparatus, which can be applied to the technical field of communications. The method configured to be executed by a terminal device comprises: receiving first downlink control information (DCI) sent by a network device, wherein the first DCI is used for indicating that there is data being transmitted during a hybrid automatic repeat request (HARQ) process; and in response to an identifier of a physical downlink control channel (PDCCH) corresponding to the first DCI being a broadcast or multicast scheduling identifier, determining, according to the type of the first DCI and content included in the first DCI, the type of data, indicated in the first DCI, transmitted during the HARQ process. Thus, a terminal device can accurately determine the type of data transmission, such that the terminal device and a network device have consistent understanding for a data transmission indication, thereby effectively avoiding data loss, and improving the reliability of data transmission.

摘要： The present disclosure provides a random access method and device, and a storage medium. The random access method comprises: receiving resource configuration information, the resource configuration information being used for configuring resources in a specified random access resource pool corresponding to at least one network slice; determining a first random access resource on the basis of slice information of a target network slice and the resource configuration information, the target network slice being a network slice for initiating random access by the user equipment (UE); and initiating random access on the basis of the first random access resource. According to the present disclosure, the possibility of a collision between a UE using a certain slice service and other UEs during random access is reduced, and the success rate of random access of a UE is improved, such that the UE can quickly complete random access to obtain a desired slice service.

摘要： The present application relates to an uplink timing advance determining method, applicable to a terminal. The method comprises: receiving common timing-related information broadcast by a cell; and determining uplink timing advance according to the common timing-related information. According to the present application, a cell does not need to indicate all uplink timing advance, but only needs to indicate common timing-related information, the common timing-related information is not greater than the uplink timing advance, and thus, it is beneficial to reducing the amount of information to be indicated. In addition, by broadcasting valid time-related information of common timing-related information, when determining according to the valid time-related information that the received common timing-related information is valid, the terminal does not need to acquire system information carrying the common timing-related information; thus, even if the common time offset is changed, the cell does not need to continuously notify the terminal of the changed common time offset, thereby reducing the signaling overhead and the power consumption of the terminal.
