摘要： A UE in a wireless communication network transmits succinct, direct channel state information to the network, enabling coordinated multipoint calculations such as joint processing, without substantially increasing uplink overhead. The UE receives and processes reference symbols over a set of non-uniformly spaced sub-carriers, selected according to a scheme synchronized to the network. The frequency response for each selected sub-carrier is estimated conventionally, and the results quantized and transmitted to the network on an uplink control channel. The non-uniform sub-carrier selection may be synchronized to the network in a variety of ways.

摘要： A joint detector that improves the performance of receiving a downlink control channel signal for a near-end mobile terminal in the presence of a stronger control channel signal addressed to a far-end mobile terminal sharing the same OVSF, or channelization, code through the use of orthogonal signature sequences. Depending on the specific embodiment, the joint detector may produce the desired bits for the control signal of interest, or may produce detected bits for all control signals sharing the same OVSF code. The joint detector despreads and combines the received code-multiplexed signal, utilizing knowledge of the cross correlations of the set of signature sequences and time-varying channel coefficients to alleviate performance degradation caused by interference from other signals. In various embodiments, the joint detector may be implemented as a modified decorrelating detector, a modified MMSE detector, a modified LS estimator detector, a successive interference-canceling detector, or a jointly hypothesized detector.

摘要： A transmitter, channel coder, and method for coding and transmitting a sequence of symbols in a digital communication system utilizing soft pilot symbols. In one embodiment, the transmitter transmits a set of soft pilot symbols with higher reliability than the remaining symbols in the sequence by modulating the soft pilot symbols with a lower order modulation such as BPSK or QPSK while modulating the remaining symbols with a higher order modulation such as 16 QAM or 64 QAM. The transmitter shares the modulation type and location (time/frequency/code) of the soft pilot symbols with a receiver. Unlike traditional fixed pilots, the soft pilots still carry some data. Additionally, the soft pilots are particularly helpful in establishing the amplitude reference essential in demodulating the higher order modulation symbols. In another embodiment, soft pilot symbols are inserted by low-level puncturing of channel encoded bits and replacing the punctured bits with known bit patterns.

摘要： A method and apparatus use unified equations to provide computationally efficient but exact solutions to bit soft value computations for Gray-coded QAM symbols in a received communication symbol as compared to carrying out region-specific equations that are keyed to particular regions of a nominal modulation constellation. Such unified equations further may include one or more correction terms that compensate the bit soft value computations for the effects on symbol samples of more than one “nearest” neighbor in the nominal modulation constellation. While the computations offer particular advantages for receivers making use of the HS-DSCHs used in WCDMA, the method and apparatus can be used in essentially any wireless receiver or system employing Gray-coded QAM.

摘要： A method and apparatus that reduces the likelihood of having a high peak power in any one bit position of code multiplexed downlink control channel symbols is described herein. An exemplary method includes selecting a different bit-level spreading sequence for each mobile terminal from a set of orthogonal bit-level spreading sequences, where code values in any one bit position are not the same for all of the bit-level spreading sequences in the set. When a code multiplexing system uses the selected bit-level spreading sequences from the sequence set to code multiplex the downlink control channel symbols, the resulting combined signal has a lower likelihood of having a high peak power.

摘要： A receiver includes a receiver circuit that decodes multiple signals of interest contained in a composite received signal. The receiver comprises a plurality of successive signal detection stages to detect respective signals contained in the composite received signal. Each detection circuit comprises at least one Generalized RAKE combining circuit and generates a detected signal at an output. Each but the last stage further comprises a signal regeneration circuit that cancels the signal of interest detected by that stage from a stage input signal provided to the next stage such that successive detection of the signals of interest benefits from cumulative cancellation of the previously detected signals.

摘要： A delayed decision feedback Log-MAP equalizer generates optimal soft information at the bit level for MPSK and MDPSK modulations over multipath fading channels. The algorithms have a forward-backward recursion structure similar to conventional Log-MAP algorithms. To reduce complexity, the forward recursion incorporates the techniques of delayed decision feedback sequence estimation to construct a reduced state space. The backward recursion then takes this state space as given, in that it does not hypothesize feedbacks, and computes required soft information.
