摘要： A user equipment (UE) in a cellular telecommunications system is able to detect the uplink/downlink configuration of a detected neighboring cell by receiving a signal from the neighboring cell. A characteristic of the received signal is detected and used as an indicator in a blind detection process to identify one or more downlink slots in the received signal. Known pilot signals in the identified one or more downlink slots can then be used to obtain a signal power measurement of the received signal. The blind detection process is also capable of detecting whether a slot of a neighboring cell's signal is a downlink unicast slot or a Multicast-Broadcast Single Frequency Network slot.

摘要： A programmable high-speed frequency divider architecture is provided that is programmable to divide an input clock signal frequency by a selectable division N. The frequency divider architecture has a shift register circuit having N/2 shift register stages, connected in series when N is an even integer and trunc[N/2]+1 shift register stages when N is an odd integer. The frequency divider architecture includes a feedback logic circuit that performs a logical NAND of the output clock signal with the logical ORed result of a pre-output signal provided from a shift register stage prior to the output stage and another signal that indicates whether the selectable divisor N is odd or even.

摘要： A receiver is operated so as to receive data conveyed on an Orthogonal Frequency Division Multiplexed (OFDM) signal transmitted on a plurality of sub-carriers. Such operation includes ascertaining which of the plurality of sub-carriers have a channel quality that satisfies one or more criteria. Then, sub-carriers are selected based at least in part on whether they have the channel quality that satisfies one or more criteria. The receiver then fully processes data streams only from the selected sub-carriers, wherein fully processing data streams comprises sub-carrier channel estimation or sub-carrier equalization or both sub-carrier channel estimation and sub-carrier equalization.

摘要： A network node comprising at least one network interface the network node arranged to form network links to other network nodes through the or each network interface, each network link being to a neighboring one of the other network nodes, the network node arranged to determine whether data transmitted over the links to the relevant neighboring network nodes is successfully received. Should the network node make a first determination that data sent over a given network link to a neighboring node has not been successfully received, the network node temporarily disables the entry for that network link in a memory for a period of time, such that the network node does not send data to the neighboring node over the given network link during the period of time, but then subsequently re-enables the entry after the period of time has elapsed. Should the network node make a subsequent determination that data sent over the given network link to the neighboring network node has not been successfully received, the network node deletes the entry from the memory.

Each step of obtaining a value of a signal feasibility parameter comprises checking whether a measured value of the signal feasibility parameter is available, and if one is, retrieving said measured value and if one is not, calculating an estimated value of the signal feasibility parameter.
