    Abstract: A SOAP-SIP adapter 2 establishes a session with the terminals 5b and 5c in accordance with a SIP. At this time, the SOAP-SIP adapter 2 sends an INVITE message including its own IP address and port number to the terminals 5b and 5c. Each terminal 5b, 5c sends a 200 OK including its own IP address and port number to the SOAP-SIP adapter 2. The SOAP-SIP adapter 2 stores correspondingly the IP address and port number of each terminal 5b, 5c in a memory. The SOAP-SIP adapter 2 transfers a media stream received from each terminal 5b, 5c to the destination of the corresponding IP address and port number by referring to the memory. Also, a pseudo RBT is sent to the terminal A5b from establishing the session with the terminal A5b till establishing the session with the terminal B5c to prevent a silent state.

    Abstract: A system for controlling a contention state for a communication link between a base station controller and customer premises equipment in point-to-multipoint communication. The contention state is controlled using a state machine, which includes a grant pending absent state in which a unicast request slot is maintained open for use by the customer premises equipment. During the grant pending absent state, the customer premises equipment sends no upstream data to the base station controller but can use the unicast request slot to request a data slot for sending upstream data to the base station controller. In the grant pending state, the customer premises equipment preferably uses piggybacking to request grant of a next data slot while sending upstream data to the base station controller.

    Abstract: In order to support low latency and bursty internet data traffic, the 3GPP LTE wireless communication system uses dynamic allocation. To keep the allocation overhead lower, the system is designed such that the client terminal must perform a number of decoding attempts to detect resource allocations. During course of the decoding attempts a false resource allocation may be decoded by the client terminal. The false detection may lead to multiple issues for the performance efficiency of the client terminal and the overall communication system. A method and apparatus are disclosed than enable the detection of false resource allocation. This in turn improves the performance and efficiency of the client terminal and the wireless communication system.

    Abstract: It is possible to provide a radio communication terminal device and a radio transmission method which can improve reception performance of a CQI and a reference signal. A phase table storage unit stores a phase table which correlates the amount of cyclic shift to complex coefficients {w1, W2} to be multiplied on the reference signal. A complex coefficient multiplication unit reads out a complex coefficient corresponding to the amount of cyclic shift indicated by resource allocation information, from the phase table storage unit and multiplies the read-out complex coefficient on the reference signal so as to change the phase relationship between the reference signals in a slot.

    Abstract: A node device includes a transmitter, processor, and a receiver. The receiver receives a packet from an adjacent node device. The processor generates a cluster list and a first hello packet. The cluster list records device identification information of a node device included in a cluster. The cluster is a group of node devices for which route information is stored. The first hello packet reports the route information with cluster identification information of the cluster. The transmitter broadcasts the first hello packet. Upon receipt of, from a free-node device that does not belong to a cluster, a second hello packet that includes information that associates the cluster identification information with device identification information of the free-node device, the processor adds the device identification information of the free-node device to the cluster list until a number of node devices recorded in the cluster list reaches a threshold.

    Abstract: A method for wirelessly transmitting data and control information using a plurality of transmission layers includes determining a number of bits in user data codewords to be transmitted during a subframe and calculating a number of control vector symbols to allocate to control information during the subframe. The number of control vector symbols is calculated based on the number of bits in the user data codewords to be transmitted during the subframe and an estimate of the number of vector symbols onto which the user data codewords will be mapped. The estimate of the number of vector symbols depends on the number of control vector symbols to be allocated to control information. The control codewords may be mapped to the calculated number of control vector symbols and transmitting vector symbols carrying the user data codewords and the control codewords over the plurality of transmission layers during the subframe.

    Abstract: Aspects describe maximizing a Euclidean distance for an ACK transmission as a function of the number of bits in a HARQ-ACK and a modulation order. Encoding includes placing escape sequences in the HARQ-ACK, wherein the number of escape sequences is based on the number of bits and the modulation order. Multiple encoded ACK blocks are combined to obtain a vector sequence that is multiplexed with the encoded data and interleaved, such as on a “time-first” manner. Scrambling is performed as a function of the size and the modulation order. For a 1-bit ACK, the scrambling is performed to achieve any two corners in any constellation for transmission for the ACK. For a 2-bit ACK, the scrambling is performed to achieve any four corners in any constellation for transmission for the ACK.
