A wireless communication unit for communicating with a wireless network node and one or more wireless remote communication units is described. The wireless communication unit comprises: at least one receiver configured to receive data content when connected to the wireless network node or a first wireless remote communication unit; at least one memory operably coupled to the at least one receiver and configured to store the received data content; at least one transmitter operably coupled to the at least one memory; and a processor operably coupled to the at least one memory and the at least one transmitter. When no longer connected to the wireless network node or the first wireless remote communication unit, the processor is configured to access the data content from the at least one memory and the transmitter is configured to transmit the accessed data content to at least one second wireless remote communication unit.

Content transfer functionality beyond or within cellular networks

A device for use in a base station receives, via the communication interface, a service request message from a first radio access technology (RAT) from a user equipment (UE), wherein the service request message includes information associated with at least one UE service, transmit, via the communication interface, based on the service request message, a message with information to setup a bearer for a second RAT to the UE, wherein the second RAT is a different RAT than the first RAT. The device for use in a base station transmits, via the communication interface, multimedia data using the second RAT to the UE, and transmit, via the communication interface, data using the first RAT to the UE, wherein the data and multimedia data are transmitted simultaneously and use a same packet data protocol and same security keys to recover the multimedia data.

Communicating over multiple radio access technologies (RATs)

A user equipment (UE) may transmit, using a first radio access technology (RAT), a service request message including information associated with at least one UE service. Based on the transmitted service request message, a message with information to setup a bearer for a second RAT, wherein the second RAT is a different RAT than the first RAT. The UE may receive multimedia data using the second RAT and simultaneously receive data using the first RAT.

A user equipment (UE) may transmit a service request using a first frequency band, the first frequency band being paired to a second frequency band to operate using frequency division duplex (FDD). The UE may further transmit a setup message over the second frequency band, the setup message indicating a third time division duplex (TDD) frequency band for communication. The UE may receive downlink data simultaneously over the second frequency band and the third TDD frequency band, wherein multimedia data is received on the third TDD frequency band.

A user equipment (UE) may communicate using a first radio access technology (RAT) having paired spectrum. The UE may receive first data over a frequency for downlink including configuration information for a second RAT. The UE may also receive second data over the second RAT having another frequency based on the received configuration information. A portion of the first data received over the first RAT may be received simultaneously with a portion of the second data over the second RAT.

A cellular communication system comprises a first base station serving at least a first user equipment. The base station comprises functionality for transmitting a base station duplex capability message to user equipments using a transmission format which is common to a plurality of duplex modes. A first user equipment comprises a transceiver which receives the base station duplex capability message. A RACH characteristics processor determines at least one transmit characteristic for an access message in response to the base station duplex capability message and a RACH transmit controller controls the transmission of an access message to the first base station in response to the at least one transmit characteristic.

A mobile communications network includes plural base stations in a network and configured to transmit to mobile communications devices a broadcast signal providing a sequence of data blocks in a sequence of transmission frames, each data block of the sequence being transmitted by each of the base stations contemporaneously for each of the sequence of transmission frames. One or more relay nodes are configured to receive the broadcast signal transmitted by one of the base stations and retransmit the broadcast signal, as the sequence of data blocks in the sequence of transmission frames on the same frequency as the broadcast signal transmitted by the base station, so that one or more of the mobile communications devices can receive the broadcast signal and recover the sequence of data blocks from one or both of the broadcast signal transmitted by the base station or the broadcast signal transmitted by the relay node.

Mobile communications network, mobile communications device, relay node and method

A mobile communications system including one or more mobile communications devices and a mobile communications network, the mobile communications network including a radio network part and a core network part and being configured to communicate data packets to and/or from mobile communications devices. Data packets can be communicated to or received from the mobile communications devices using either a broadband packet network or a dedicated messaging network. The dedicated messaging network is arranged to communicate short data grams more efficiently than larger data communications. Therefore by selecting either the dedicated messaging network or the broadband network as a function of content of the data packet a more efficient use of available communications resources and hardware resources is realized.

Mobile communications system, infrastructure equipment, base station and method

A cellular communication system comprises a Multiple-In Multiple-Out, MIMO, transmitter and receiver. The MIMO transmitter comprises a message generator for generating MIMO messages comprising selected training sequences and transceivers transmitting the messages on a plurality of antennas. The training sequences are selected by a midamble selector from a set of training sequences in response to an associated antenna on which the message is to be transmitted. The set of training sequences is associated with the cell of the MIMO transmitter and comprises disjoint subsets of training sequences for each of the plurality of antennas. The receiver comprises a transmit antenna detector which determines which antenna of the MIMO transmitter the message is transmitted from in response to the training sequence of the received message.
