摘要： A terminal device for use with a wireless telecommunications system, the terminal device comprising: a transmitter; a receiver configured to receive a measurement radio signal from each of one or more potential relay nodes of the wireless telecommunications system, each measurement radio signal being transmitted using the same predetermined radio frequency band and identifying the one of the potential relay nodes from which it is transmitted; and a controller configured: to measure a characteristic of each received measurement radio signal, and based on each received measurement radio signal and its measured characteristic, to determine a suitable one of the one or more potential relay nodes for acting as a relay node for relaying the further radio signal between the terminal device and the infrastructure equipment.

摘要： A first network access node for use with a handover procedure for a terminal device involving the first network access node and a second network access node. The first network access is configured to receive a block of uplink data from the terminal device and establish whether the block of data has been ciphered by the terminal device using a cipher key corresponding to a first cipher key or to a second cipher key. In response to establishing the block of data has been ciphered using a cipher key corresponding to the first cipher key, decipher the block of data using the first cipher key. In response to establishing the block of data has been ciphered using a cipher key corresponding to the second cipher key, forward the block of data to the second network access node.

摘要： A base station for a mobile telecommunications system has circuitry which is configured to communicate with at least one user equipment. The circuitry is further configured to: transmit a short data transmission within the time scheduled for a long data transmission; and schedule, based on the transmission of the short data, a HARQ ACK/NACK response relating to at least a part of the long data transmission.

摘要： A method of operating a second network access node comprises configuring the second network access node to act as a secondary network access node for a dual connectivity mode for a terminal device in which a first network access node acts as a master network access node. The method further comprises establishing, while acting as a secondary network access node for the dual connectivity mode, that the second network access node should switch to acting as a master network access node, deriving a new master network access node security key for use by the second network access node when switched to acting as a master network access node for the dual connectivity mode, and configuring the second network access node to act a master network access node for the dual connectivity mode using the new master network access node security key.

摘要： A terminal device comprises a transmitter, a receiver and a controller. The transmitter is configured to transmit a first radio signal to infrastructure equipment of a wireless telecommunications system, the first radio signal being repeatedly transmitted a predetermined number of times during each of a plurality of consecutive time periods, each of the consecutive time periods being separated by a separation time period. The receiver is configured to receive, from the infrastructure equipment during one of the separation time periods, a second radio signal that comprises an indicator indicating that transmission of the first radio signal should continue or that transmission of the first radio signal should be terminated and the second radio signal having a measurable characteristic on the basis of which the terminal device reduces an offset of a reference radio frequency of the terminal device relative to a transmission radio frequency of the infrastructure equipment.
