Abstract: An entity establishment processing method and an apparatus are provided. The processing method includes: A terminal side device receives first indication information from a first network side device, where the first indication information is used to trigger reestablishment of a first PDCP entity of the terminal side device. When a first bearer corresponding to the first PDCP entity is not a radio bearer used to perform duplication transmission between the terminal side device and a core network side device, in a process in which the terminal side device reestablishes the first PDCP entity based on the first indication information, the terminal side device sets a parameter of the first PDCP entity to an initial value.

Abstract: Embodiments of this application provide a random access processing method. A random access preamble and uplink data are sent in an initiation phase of a random access procedure, and the random access procedure is ended in time after feedback information for the uplink data is received. According to technical solutions provided in the embodiments of this application, a terminal side device may send the uplink data when sending the random access preamble in the random access procedure. In addition, the random access procedure can be ended in advance after the feedback information for the uplink data is received.

Abstract: Embodiments of this application provide a data transmission method and apparatus. The method includes: receiving data sent by a terminal in an inactive state, where the data includes to-be-sent data sent by the terminal and identification information of the terminal; determining an anchor base station of the terminal based on the identification information; and sending the data to the anchor base station, so that the anchor base station sends the data to a core-network device. The uplink data of the terminal is forwarded to the anchor base station by using a serving base station and through an interaction between the anchor base station and the serving base station that currently provides an air interface resource for the terminal, and is then transmitted to a core network.

Abstract: An uplink signal control method and apparatus, which are used to resolve a problem that when a UE is not within primary carrier signal coverage of a micro cell, the micro cell cannot control uplink transmission of the UE on a primary carrier. The method includes: determining, by a first network device, uplink control configuration information for user equipment (UE), where the uplink control configuration information includes information about a control channel occupied by control information, which is transmitted by a second network device on a second carrier, for controlling an uplink transmission action of the UE on a first carrier; and notifying, by the first network device, the uplink control configuration information to the second network device, and sending the uplink control configuration information to the UE or instructing the second network device to send the uplink control configuration information to the UE.

Abstract: Embodiments of the present invention provide a downlink information processing method and a device. The method includes: determining, by UE, whether a communication link between a cell in an active set and the UE meets a preset communication quality requirement; and if the communication link between the cell in the active set and the UE does not meet the preset communication quality requirement, stopping, by the UE, processing downlink information that is sent from a base station by using the communication link; therefore, transmission performance of the UE is not affected.
