Abstract: An optical multi carrier signal has a modulation format and has many individual carrier signals. Parameters of the signal are controlled by receiving an indication of individual carrier transmission performance of the individual carrier signals, and selecting parameter values for the individual carrier signals, the parameter values comprising both a carrier FEC overhead and a carrier bandwidth for the modulation format. Selection is made according to the indicated individual carrier transmission performance and according to an overall spectral efficiency of the multi carrier signal. The selected parameter values are output for control of the optical multi carrier signal. By selecting values for both parameters rather than either one, better optimisation can be obtained since they are interdependent. The control can have better granularity than changing modulation format, and can make better use of bandwidth or improve the overall capacity.

Abstract: Apparatus and methods for rate prediction in a wireless communication system having fractional frequency reuse are disclosed. A wireless communication system implementing Orthogonal Frequency Division Multiple Access (OFDMA) can implement a fractional frequency reuse plan where a portion of carriers is allocated for terminals not anticipating handoff and another portion of the carriers is reserved for terminals having a higher probability of handoff. Each of the portions can define a reuse set. The terminals can be constrained to frequency hop within a reuse set. The terminal can also be configured to determine a reuse set based on a present assignment of a subset of carriers. The terminal can determine a channel estimate and a channel quality indicator based in part on at least the present reuse set. The terminal can report the channel quality indicator to a source, which can determine a rate based on the index value.

Abstract: A 10GBASE-T circuit is disclosed. The circuit includes a physical (PHY) integrated circuit and a media access control (MAC) integrated circuit. The PHY couples to a data transfer medium and carries out data transfers at a PHY data rate.

Abstract: A method is disclosed that can be performed in at least one network node which provides wireless communications service for user equipment nodes (UEs). The method includes detecting uplink interference at an interfered network node. Responsive to the uplink interference, an uplink transmission having a defined configuration is initiated from a UE, which is served by a serving network node. The uplink signal is detected using the defined configuration at the interfered network node. The UE is identified responsive to the detected uplink signal as being a contributor to the uplink interference. An uplink transmission by the UE and/or by another UE served by the serving network node is controlled to reduce uplink interference.

Abstract: A transmission apparatus controls a transport format for retransmission of data packets transmitted uplink to a receiving apparatus via at least one data channel using an automatic repeat request (ARQ) protocol. A transmitter transmits an uplink data packet via the data channel to the receiving apparatus, and a receiver receives first information along with second information from the receiving apparatus. The first information is used for determination whether to perform a retransmission of the uplink data packet at the transmission apparatus, and the second information indicates a transport format for the retransmission. The transmitter transmits the retransmission from the transmission apparatus to the receiving apparatus according to the transport format indicated in the second information element using a transmission timing based on the ARQ protocol.
