摘要： A radio base station, user equipment (UE), and method of control signaling in wireless communication systems. Control information is transferred from a base station to at least one UE, via a plurality of common pilot channels. A set of unique pilot sequences is predefined, and the base station assigns specific pilot sequences from the set of pilot sequences to specific common pilot channels, forming a pilot sequence assignment pattern representing specific control information. The UE, having knowledge of the relations between pilot sequence assignment patterns and control information, interprets the received pilot sequence assignment pattern as specific control information. The method is particularly well suited for broadcast type control information.

摘要： A block coding method and system for improving the reliability of Channel Quality Indicators (CQI) and antenna weight indicators (AWI) reporting. A user terminal first generates 8-bit CQI and 2-bit AWI. A codeword generator produces a codeword responsive to these 10 CQI/AWI bits using a codebook or a generator matrix of a (20,10,6) code. The (20,10,6) code has a minimum Hamming distance of 6 The encoded codeword is transmitted to a receiver for decoding utilizing an identical (20,10,6) codebook.

摘要： Methods and apparatus are disclosed for transmitting data to a remote node via each of two or more transmitted carrier signals, wherein a distinct outbound packet data traffic channel is mapped to each transmitted carrier signal. In an exemplary method, aggregated control channel data is formed by combining control channel data corresponding to each of two or more received carrier signals, simultaneously transmitting traffic channel data to the remote node on each of the two or more outbound packet data traffic channels, and transmitting the aggregated control channel data using one or more physical control channels mapped to a first one of the transmitted carrier signals. In particular, these methods and apparatus may be applied to a multi-carrier High-Speed Packet Access (HSPA) system.

摘要： A signal is received containing a block of multiple symbols, each symbol containing information bits spread by a spreading sequence of chips. Each spreading sequence is determined by a channelization sequence and a first or second complex-valued scrambling sequence of chips. Each block is processed using a set of spreading sequences using correlations between pairs of spreading sequences in the set. Spreading sequence correlation values between each pair are manipulated and stored in lookup tables. A lookup table address is determined using a first set of reduced basic scrambling bits to retrieve correlation values. The first set of reduced basic scrambling bits is based on manipulation of one set of the basic scrambling bits that reduces a number of bits included in the determined address to less than a number of binary values in the one set of basic scrambling bits. The one set of basic scrambling bits is used to construct one of the first and second complex-valued scrambling sequences. The retrieved correlation values may be used in mitigating spreading sequence correlation interference between spreading sequences in the set.

摘要： In MU-MIMO scenarios, a target terminal can be exposed to data streams intended for other terminals. If the target terminal is capable of interference cancellation, then a network node, such as a base station or RNC, can provide the target terminal with interference information so that the target terminal can efficiently cancel interferences due to these interfering data streams. The interference information may include one or more interfering configuration, each of which characterizes a related interfering data stream. The interference information can also include the identity of the other terminal that is the intended recipient of the interfering stream. The network node may determine whether the target terminal can benefit from the interference information. If so, the network node can provide the interference information to the target terminal.

摘要： Systems and methods are disclosed for measuring received signal power at a mobile terminal in a cellular communications network in such a manner as to efficiently provide highly accurate received signal power measurements in the presence of strong inter-cell interference. In one embodiment, in order to measure received signal power for a measured cell, a mobile terminal selects weighting parameters for a number of time-frequency samples of a reference signal of the measured cell based, at least in part, on inter-cell interference from one or more synchronized interfering cells and inter-cell interference from one or more non-synchronized interfering cells. The mobile terminal applies the time-frequency samples of the reference signal of the measured cell and the corresponding weighting parameters to corresponding time-frequency samples of a received signal from the measured cell in order to obtain a measurement of the received power for the measured cell.
