Abstract: Disclosed are a terminal state conversion method and apparatus. A base station configures and sends a configuration policy for/to a terminal, wherein the configuration policy is a rule for determining that the terminal enters an inactive state; and a terminal in a connected state receives the configuration policy sent by the base station, and according to the configuration policy, enters the inactive state from the connected state. By means of the present invention, a terminal enters an inactive state from a connected state, and thus the terminal can perform rapid data transmission while saving power.

Abstract: A method and a device for transmitting uplink data are provided. The method includes sending, by a UE, an initial uplink transmission carrying an inactive-state UE identifier of the UE in uplink contention resources available in a region, in case that uplink data of the UE in an inactive state arrives; and receiving a feedback acknowledgement message for acknowledging the initial uplink transmission.

Abstract: The present invention discloses a method and device for judging Radio Link Failure (RLF) in Carrier Aggregation (CA) technology, which are used to effectively judge whether a radio link is failed or not in CA technology. Said method comprises: on an evaluation point, comparing the determined radio link quality parameter of each carrier participating in the RLF judgement with the corresponding radio link quality parameter threshold, determining whether to trigger an in-sync indication or out-of-sync indication on the evaluation point, and judging whether the radio link of the User Equipment (UE) is failed according to the number of the continuously received in-sync indications or out-of-sync indications. The embodiment of the present invention determines whether to trigger an in-sync indication or out-of-sync indication by comparing the radio link quality parameters of the carriers participating in the RLF judgement with the corresponding radio link quality parameter thresholds, and thereby judges that whether the radio link is failed or not in CA technology.

Abstract: A method and an apparatus for maintenance of a bandwidth part. The method and apparatus resolve an issue of the prior art in which expiration of a bandwidth part deactivation timer during a random access process changes the bandwidth part to a default bandwidth part, such that data cannot be transmitted on an optimal bandwidth part, and may even cause an interruption of an ongoing data transmission, while also affecting an ongoing random access process. In embodiments of the present invention, a terminal keeps a current active bandwidth part unchanged during a random access process, and performs a restart operation of a bandwidth part deactivation timer after the random access process is successfully completed, such that a situation where a bandwidth part changes to a default bandwidth part does not occur during the random access process, thereby reducing interruption to ongoing data transmissions and reducing the impact on ongoing random access processes.

Abstract: The present disclosure provides a retransmission activating/deactivating method, a base station, a user equipment and a device. The method includes: determining a correspondence relationship between a bearer which is allowed for retransmission under the first base station and a bit of a preset field of media access control (MAC) control element (CE) of the first base station for activating/deactivating retransmission; where the preset field is used to indicate activation/deactivation retransmission of the bearer which is allowed for retransmission; and, when determining to activate/deactivate retransmission of the bearer which is allowed for retransmission under the first base station, populating, by the first base station, the bit, which is in the preset field of the MAC CE for activating/deactivating retransmission and corresponding to the bearer, thereby generating the MAC CE for activating/deactivating retransmission, and transmitting to the UE the generated MAC CE for activating/deactivating retransmission.
