A satellite reception assembly that provides satellite television and/or radio service to a customer premises may comprise a wireless interface via which it can communicate with other satellite reception assemblies. Wireless connections between satellite reception assemblies may be utilized for providing satellite content between different satellite customer premises. Wireless connections between satellite reception assemblies may be utilized for offloading traffic from other network connections.

The apparatus may be a base station. The apparatus processes a first group of synchronization signals. The apparatus processes a second group of synchronization signals. The apparatus performs a first transmission by transmitting the processed first group of the synchronization signals in a first synchronization subframe. The apparatus performs a second transmission by transmitting the processed second group of the synchronization signals in a second synchronization subframe.

Devices, systems and methods for high-utilization low-latency multi-channel time-division multiplexing access (TDMA) are described. One example method for wireless communication includes performing, in a first time interval of a time-division multiple access (TDMA) slot, a transmission of a first data unit over a first logical channel of the plurality of logical channels, refraining from transmitting, subsequent to a completion of the transmission of the first data unit, for a second time interval immediately after the first time interval, and performing (N−1) transmissions in (N−1) time intervals for each data unit of (N−1) subsequent data units in the TDMA slot, such that a transmission of an nth data unit of the (N−1) subsequent data units is performed over an nth logical channel of the plurality of logical channels.

Consistent with the present disclosure, the above-described subcarrier noise, which may be characterized as a linear filtering effect, may be reduced or eliminated by providing a first multiple-input multiple output (MIMO) circuits at the transmit end of an optical link and providing a second MIMO circuit at the receive end of the optical link. The first MIMO may include a first plurality of filters, each of which may include a finite-impulse response (FIR) filter having variable coefficients or tap weights that may be changed or adapted to minimize subcarrier noise associated with the modulator, as well as D/A and analog circuitry, at the transmit end of the optical link. In addition, the second MIMO may include a second plurality of filters, each of which may also include an FIR filter having variable coefficients or tap weights that may be changed or adapted to minimized subcarrier noise associated with the optical hybrids, as well as A/D and analog circuitry, at the receive end of the optical link. In one example, a least means square (LMS) technique may be employed to calculate desired coefficients or tap weights whereby an error determined based on the signal detected at the receiver is minimized to update the coefficients of the FIR filters.

A method (900) includes delivering a first bias current (I.sub.GAIN) to an anode of gain-section diode (590a) and delivering a second bias current (I.sub.PH) to an anode of a phase-section diode (590b). The method also includes receiving a burst mode signal (514) indicative of a burst-on state or a burst-on state, and sinking a first sink current (I.sub.SINK) away from the first bias current when the burst mode signal is indicative of the burst-off state. When the burst mode signal transitions to be indicative of the burst-on state from the burst-off state, the method also includes sinking a second sink current away from the second bias current at the anode of the phase-section diode and ceasing the sinking of the first sink current away from the first bias current at the anode of the gain section diode.

A communication system includes a communication apparatus and a base station. The communication apparatus includes a Discrete Fourier Transform (DFT) transformer which transforms a time-domain signal into a frequency-domain signal with a DFT size that is a product of powers of a plurality of values; a mapper which maps the frequency-domain signal on a plurality of frequency bands, each frequency band being located at a position separate from position(s) of other(s) of the plurality of frequency bands; and a signal generator which generates a single carrier-frequency division multiple access (SC-FDMA) time-domain signal from the mapped signal. The base station includes a receiver which receives the SC-FDMA time-domain signal; a combiner which generates the frequency-domain signal from the SC-FDMA time-domain signal; and a transformer which transforms the frequency-domain signal into the time-domain signal with an inverse Discrete Fourier Transform (IDFT) having the DFT size.

A user equipment, a network node and methods thereof for timing of scheduling of resources in a frequency division duplex system are disclosed. The user equipment and network node operate in a frequency division duplex communication system. The network node determines (400) whether a user equipment is prohibited to receive an uplink grant in at least one downlink subframe, e.g. if the user equipment is configured with ABS or with half-duplex operation. Furthermore, if the user equipment is prohibited to receive an uplink grant in at least one downlink subframe, the network node sends (410) an indication to the user equipment to apply a time division duplex configuration to the timing of scheduling of resources. The user equipment receives (420) the indication and thereupon applies (430) the time division duplex configuration to the timing of scheduling of resources.
