A terminal apparatus and retransmission control method reduces overhead of the uplink control channel in cases when ARQ is applied in communication that uses an uplink unit band and a plurality of downlink unit bands associated with the uplink unit band. A first condition is set in which downlink assignment control information is transmitted from a base station by a unit band group which comprises a basic unit band, which is the downlink unit band on which a broadcast channel signal including information relating to the uplink unit band is transmitted, and a second downlink unit band other than the basic unit band. A bundling unit will not transmit a response signal to the base station in certain cases.

The present invention provides methods and apparatus for implementing spatial multiplexing in conjunction with the one or more multiple access protocols during the broadcast of information in a wireless network. One example includes transmitting a first and a second data signal to a remote unit from a respective first and a second spatially separate antenna of a base station so that the first and second data signals have a first spatial configuration, determining that the first and the second data signals are not spatially separated by the remote unit, reconfiguring the (spatial multiplexing logic 104) spatial configuration of the first and second data signals to a second spatial configuration, and transmitting a third and fourth data signal to the remote unit from a second different antenna configuration according to the second spatial configuration.

The present invention relates to a method for converting, by a station (STA), a non-traffic indication map (TIM) mode into a TIM mode and performing channel-accessing. According to the present invention, a station that does not receive a TIM or DTIM is to be switched so as to operate between a wakeup mode and a sleep mode for power saving. In order to set an efficient wakeup time, the STA may listen to beacon frame information from an AP and access a channel through information included in the beacon frame information.

A method in, and a Broadcast Management unit (130) for providing digital content to a user equipment (120), and a method in, and a user equipment (120) for receiving digital content. The user equipment (120) is served by a base station (110) in a cell (115) of a cellular communications network (100). The Broadcast Management unit decides (301) to provide a digital content by broadcast or multicast in a service area (105) comprising the cell (115), instead of only letting the digital content be available in the service area (105) by unicast. The Broadcast Management unit provides (302-304), in response to the decision, broadcast or multicast of the digital content in the service area (105), thereby enabling reception of the digital content by the user equipment (120) via the base station (110) and by one or more additional user equipments (121, 122, 123) being served in the service area (105). As a result, improvement of performance is enabled in the cellular communications network.

Systems and methods are disclosed herein for wireless audio distribution for improved performance. The method can include receiving, at a configurable software-defined hub, a pairing initiation signal to connect the hub with at least one node of one or more configurable software-defined nodes. The method can include receiving, from the at least one node, a plurality of node identifiers; authorizing the at least one node based on a comparison of the plurality of node identifiers and identifier data stored in the hub memory; securely pairing the configurable software-defined hub with at least one authorized node; configuring a software-defined transceiver chain comprising a configurable hub transmitter and an authorized node receiver with a modified Logical Link Control layer and an unmodified Media Access Control layer of an Open System Interconnect protocol, and communicating data in a predetermined format from the configurable hub transmitter to the authorized node receiver.

Disclosed herein are methods and systems that may help a base station provide high-speed data communication under a protocol such as LTE or WiMAX, even when a GPS signal is not available to the base station. In an exemplary embodiment, a base station may acquire a high-stability reference signal via a subcarrier of a terrestrial broadcast signal, such as an FM radio signal, and may coordinate the timing frame transmissions with other nearby base stations, instead of relying upon a GPS signal for such functionality.

Provided is an operation method of a coordinator, the method including receiving a data packet from a node, configuring bitmap information indicating whether the data packet is received, and broadcasting a beacon packet including the bitmap information indicating whether the data packet is received.

A method of reducing interference between wireless networks operating on channels with different bandwidths is proposed. One wireless network operates on a narrow band channel while the other network operates on a wide band channel that overlaps the narrow band channel. The method involves communicating information regarding the wide band channel to the devices of the network operating on the narrow band channel. A device in the network operating on the wide band channel constructs a special frame that carries its network ID as well as information regarding the wide band channel that it is operating on, namely the center frequency and the channel bandwidth. The device then broadcasts this frame on the narrow band channel. In addition, this frame is protected from possible collision by preceding the transmission of the frame by protection frames on both the channels.
