Abstract: Aspects of this disclosure mitigate interference in a time division duplexed frame by altering a transmission parameter of grant-based uplink transmissions upon determining that a portion of the grant-based transmission will coincide with the retransmission of a detected grant-free uplink transmission. In particular, a base station may determine that a grant-free retransmission is to occur over resources scheduled to carry a grant-based transmission, and then send a signal instructing a UE to delay, or puncture a portion, of the grant-based transmission. This may mitigate interference between the grant-based transmission and the grant-free transmission.

Abstract: The present application relates to a user accessing to a visited network in a wireless telecommunication network. After receiving an access request from the user for selecting a visited network and detecting the visited network selected by the user has changed, an AAA server device initiates a request for obtaining authentication and/or authorization information of the user from a HSS. In the process of obtaining the authentication and/or authorization information, the HSS checks whether the user is authorized to access to the visited network according to a list of authorized visited networks stored in the HSS.

Abstract: The embodiments of the present invention provide a physical-layer-based handover method. The method includes: generating handover signaling, where the handover signaling carries a signaling type identifier and a destination identifier that are used for handover, and the handover signaling is an HS-SCCH order or specific HS-SCCH signaling; and sending the handover signaling to a physical layer of a mobile terminal, so that the mobile terminal executes handover according to the handover signaling to be handed over to a small cell indicated by the destination identifier. A handover method based on a network side physical layer and a mobile terminal physical layer is provided, and even if cell IDs of a macro cell and a small cell or those of small cells are the same, handover of the mobile terminal can be implemented.

Abstract: Provided in embodiments of the present invention are a method and a device for transferring data. The method includes: transferring data to a base station via a first link, a second link offloading for the first link; if a radio link failure (RLF) occurs on the first link, transmitting an RLF indication message to the base station, where the RLF indication message is used to notify the base station that the RLF occurs on the first link; and transferring, over the second link, at least a portion of the data on the first link. According to embodiments of the present invention, when a link failure occurs between a user equipment and the base station during a mobile data offloading process, data transfer is performed via the offloading link, a time delay can be reduced and the data transfer efficiency is improved.
