Abstract: Frames in a variable length frame format which are addressed to a plurality of users are multiplexed and preferably transmitted. Data frames having different lengths are multiplexed on a same time through space division multiple access, but since the multiplexed frames are transmitted while eventually having a same length, when the multiplexed data frames from the access point STA0 are received in the respective communication stations STA1 to STA3 in FIG. 4 or when data simultaneously transmitted from the respective communication stations STA1 to STA3 are received in the access point STA0 in FIG. 5, it is possible to eliminate an operation instability of AGC.

Abstract: A method of transmitting downlink data in a mobile communications system, wherein the mobile communications system comprises a base station configured to communicate wireless signals to one or more terminal devices. The method comprises receiving an indicator of a maximum number of downlink repetitions “Nmax” currently accepted by a terminal device, wherein a number of downlink repetitions indicates a number of times that the same signal is transmitted to the terminal device; setting an actual number of downlink repetitions “Ntx” so that the actual number of downlink repetitions meets the condition Ntx≤Nmax; and transmitting the downlink data, to the terminal device, wherein the downlink data is transmitted via a signal transmitted a number of times equals to the actual number of downlink repetitions.

Abstract: A communications device comprising a transmitter, a receiver and a controller operable to transmit and to receive signals representing data to and from a network element across a first wireless access interface, the first wireless access interface being provided by the network element and access to resources of the first wireless access interface being controlled by the network element. The controller is configured to control the receiver to perform detection of signals transmitted across a second wireless access interface, and to control the transmitter to transmit a reporting message to the network element across the first wireless access interface, the reporting message including an indication of one or more properties of signals that have been detected across the second wireless access interface.

Abstract: A user device is arranged to transmit and receive data via a wireless access interface including a plurality of Orthogonal Frequency Division Multiplexing subcarriers extending across a first bandwidth. The user device is configured to receive one or more signals repeatedly transmitted across a second bandwidth and not across subcarriers of a first bandwidth outside of the second bandwidth, store second signals in a memory. The user device is further configured to combine the stored second signals to generate a combined signal, detect the user device payload data from the combined signal based on an indication of the second bandwidth when the user device indication, and when the user device fails to detect the indication, accumulate three consecutive subframes of the signals received across the second bandwidth, and detect the user device payload data from the combined signal based on information included in the three consecutive subframes.

Abstract: A wireless resource is utilized efficiently.An information processing apparatus is an information processing apparatus that includes a control unit. The control unit provided in the information processing apparatus performs control for aborting, when a packet decided to be transmitted from a second network different from a first network to which the own apparatus belongs is detected, reception of the packet. Further, the control unit provided in the information processing apparatus performs control for dealing with carrier sense as an idle state based on a reception strength of the packet decided to be transmitted from the second network.

Abstract: An information processing apparatus includes a control section, and can temporarily pause at least some of its own functions. The control section of the information processing apparatus performs control for notifying, when at least some of its own functions are to be temporarily paused, a first apparatus that has a specific function of a function temporary pause period within which at least some of functions of the first apparatus are to be temporarily paused. Further, the control section of the information processing apparatus performs control for directing, when at least some of its own functions are to be temporarily paused, a second apparatus that does not have a specific function to restrain transmission. Power consumption of the information processing apparatus can be reduced.

Abstract: A mobile communications network includes one or more network elements providing a wireless access interface for communications devices. The wireless access interface provides plural communications resource elements across a host frequency bandwidth, and includes, within the host frequency bandwidth, first communications resource elements within a first frequency bandwidth for allocation preferably to reduced capability devices to receive signals representing the data transmitted by the transmitter unit within the first bandwidth forming a first virtual carrier, the reduced capability devices each having a receiver bandwidth which is greater than or equal to the first frequency bandwidth but less than the host frequency bandwidth. Communications devices of different capabilities can be allocated communications resources within different frequency ranges according to their capability, which can relieve congestion on a centre frequency of communications resources in which communications devices with a minimum bandwidth capability must receive communications resources for receiving down link signals.
