Abstract: A source device communicates multimedia data to a sink device over a multimedia channel of a multimedia link. The source device comprises an interface to a full duplex control channel of the multimedia link. The source device also comprises first arbitration logic to control transfer of control data with the sink device via the full duplex control channel. The first arbitration logic ignores requests to receive inbound control data from the sink device while the source device is transmitting outbound control data to the sink device. The sink device, on the other hand, comprises second arbitration logic to control transfer of control data with the source device via the full duplex control channel. The second arbitration logic stops transmitting outbound control data via the full duplex control channel responsive to receiving a request to receive incoming control data from the source device.

Abstract: Disclosed are methods of exchanging messages necessary for interaction among entities in a coexistence management system that manages a plurality of frequency sharing devices. Specifically, a method of exchanging messages in a coexistence management system including a coexistence enabler (CE), a coexistence manager (CM), and a coexistence discovery and information server (CDIS) includes generating, by the CM, a ReconfigurationRequest message, sending the ReconfigurationRequest message to the CE, and waiting for a ReconfigurationResponse message from the CE. The ReconfigurationRequest message includes at least one of an operating channel list of a white space object (WSO) served by the CE, a transmission power limitation, a flag indicating whether or not a channel is shared, a transmission schedule, and channel classification information.

Abstract: A method is described for receiving data from a base station by a first type user equipment (UE) capable of using a plurality of frequency bands based on resource allocation in a first wireless mobile communication system capable of using the plurality of frequency bands. Each of the plurality of frequency bands has a respective bandwidth for a second wireless mobile communication system. Specific control information is received from the base station indicating whether a specific frequency band among the plurality of frequency bands is used for downlink resource allocation or not. Control information reception resources comprise a common resource area and a first type UE-specific resource area. The common resource area is for both the first type UE and a second type UE, the second type UE adapted for the second wireless mobile communication system not capable of using the plurality of frequency bands.

Abstract: Examples are disclosed for forwarding channel condition information for a wireless communication channel and precoding data to be transmitted over the wireless communication channel based on the forwarded channel condition information.

Abstract: Disclosed are a method for transferring control information, a transmitting device and a receiving device, the method includes that: a transmitting end orderly selects an element yn or two elements y2m?1, y2m, from a sequence Y to be modulated corresponding to control information B newly added, then it selects pairing elements x2p?1, x2p from a sequence X to be modulated corresponding to related control information A, and groups yn or y2m?1, y2m and the x2p?1, x2p into an element group (x2p?1, x2p, yn) or (x2p?1, x2p, y2m?1, y2m) and maps (x2p?1, x2p, yn) or (x2p?1, x2p, y2m?1, y2m) as specified constellation points of a specified constellation diagram, and takes the constellation points as modulation symbols; it takes each two elements in the elements of the sequence X which are not used for pairing as an element group to perform QPSK modulation, modulating into QPSK modulation symbols; and it maps the constellation points and the QPSK modulation symbols to part of or all resources occupied by a correspondin

Abstract: Provided are a radio terminal device, a radio base station device, and a channel signal forming method which can prevent quality degradation of the downlink resource allocation information by reducing the frequency of the zero information addition process to the downlink resource allocation information when executing communication using an uplink unit band and multiple downlink unit bands correlated to the uplink unit band. A base station includes: a PDCCH generation unit which includes the uplink allocation information relating to the uplink unit band only in some of the channel signals formed for each of the downlink unit bands; and a padding unit which adds zero information to the downlink allocation information only in the selected some channel signals having the bandwidth of the corresponding downlink unit band smaller than that of the uplink unit band until the downlink allocation information size becomes equal to the uplink allocation information size.

Abstract: A sounding method utilized for a wireless communication system is disclosed. The sounding method comprises classifying a plurality of stations of the wireless communication system into a plurality of groups, and determining a plurality of initial sounding instants and a plurality of sounding periods corresponding to the plurality of groups; and performing sounding to at least one or all of the plurality of groups in a group by group fashion according to the plurality of initial sounding instants and the plurality of sounding periods.

Abstract: The present invention relates to a method and an apparatus for a terminal to perform interference measurement in a wireless communication system. More specifically, the method comprises the steps of: receiving a first interference measurement resource setting and a second interference measurement resource setting for one channel state estimation process (Channel State Information Process); and performing interference measurement on an interference measurement resource based on the first interference measurement resource setting and the second interference measurement resource setting, wherein the first interference measurement resource setting is set for an aggregation of first downlink subframes, in which the use of a wireless resource is set not to be changed by a repurposing message, and the second interference measurement resource setting is set for an aggregation of second downlink subframes, in which the use of the wireless resource is set not to be changed by the repurposing message.
