摘要： In a receive node of a wireless network, an iterative multi-user multi-stage interference cancellation receiver is used. After each stage of interference cancellation, interference characteristics change. An adaptive strategy is used in which after each stage of interference cancellation, impairment covariance is parametrically updated and combining weights of the receiver are adapted to reflect the updated impairment covariance.

摘要： A system and method to use existing Long Term Evolution (LTE) and Worldwide Interoperability for Microwave Access (WiMAX) based signaling to effectuate dual-channel Time Division Duplex (TDD) communication between two transceivers giving preference to one type of subframes (either downlink or uplink) for data transmission. In backhaul communications between pico (or femto) and macro base stations, using LTE and WiMAX's TDD mode in such a manner effectively reduces unnecessary transmissions of pilot and synchronization sequence in downlink signaling, thereby reducing the level of pilot overhead and minimizing interference when data is not being transmitted. Similarly, the use of existing LTE (or WiMAX) implementations of TDD radio frames in this manner may achieve radio silence for some duration (e.g., when no uplink sub-frames are transmitted) when operating in a license-exempt spectrum, thereby allowing other license-exempt devices to potentially share the radio channel during the silence period.

摘要： Control channel information is formulated for transmission in orthogonal frequency division multiplexing (OFDM) systems. In an example embodiment, a method entails formulating control channel information for a transmitting device operating in an OFDM system in which a control channel spans n OFDM symbols, with n being an integer. The method includes acts of allocating, creating, and mapping. Control channel data is allocated to at least one set of resource element groups. At least one order for the set of resource element groups is created in accordance with one or more permutation mechanisms that involve at least one interleaving sequence having a low cross-correlation property. The set of resource element groups is mapped to resource elements of the n OFDM symbols of the control channel responsive to the order that is created using the permutation mechanism(s). The permutation mechanisms may include interleaving sequence(s) and/or cyclic shift(s).

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 system, method and node for modulation and coding scheme adjustment for a Long Term Evolution (LTE) shared Data Channel. The method determines an actual number of orthogonal frequency division multiplexing (OFDM) symbols, NOS utilized for the shared Data Channel. A modulation order for transmission of data on the shared Data Channel is increased when the actual number of OFDM symbols NOS is less than 11 and decreased when NOS is more than 11. A modulation and coding scheme field (IMCS) of a downlink control information of the shared Data Channel may also be determined. If 0≦IMCS+11−NOS≦28, the modulation order is modified by utilizing a factor of (IMCS+11−NOS) in a standardized modulation scheme. If it is determined that IMCS+11−NOS 28, the modulation order is set to 64 Quadtrative Amplitude Modulation (64QAM).

摘要： Diversity radio transmission is accomplished with excellent performance using multiple antennas receiving a transmission signal from a single power amplifier. A data signal to be transmitted is provided to a first antenna, and a phase-shifted version of the data signal is applied a second antenna. The relative phase shift between the data signal transmitted over the two transmit antennas ensures the two antenna signals can be constructively combined at the receiver. In one non-limiting example embodiment, the relative phase shift is determined by processing pilot signals sent along with the data signal and which are transmitted with predetermined phase shifts.

摘要： In a method of operating a communication network (20) a time division duplex (TDD) frame (F) of information is communicated over a radio interface (32) between a wireless terminal (30) and a base station node (28). The method comprises the wireless terminal (30) receiving plural downlink (DL) subframes of the frame and, in response thereto, configuring a Physical Uplink Control Channel (PUCCH) channel to comprise up to four acknowledgements by using only two PUCCH channel resources and using PUCCH format 1a or PUCCH format 1b. In an example embodiment a PUCCH channel resource is specified by a sequence utilized for transmission of at least part of the PUCCH channel and a cyclical shift applied to the sequence. The two sequences of the respective two PUCCH resources are orthogonal, and the cyclical shift of the two PUCCH resources can be in a frequency domain, a time domain, or both the frequency domain and the time domain.
