Abstract: A base station (20A) is configured to transmit user data to a wireless device (16A) upon a first carrier (22). The base station (20A) identifies, from a set of transmission resources that is nominally allocated for transmission of user data upon the first carrier (22), a subset of transmission resources that is also nominally allocated for transmission of a reference or control signal either by the base station (20A) upon a second carrier (24) or by a neighboring base station (20B) upon the first carrier (22). The base station (20A) selectively transmits user data to the wireless device (16A) upon the first carrier (22) exclusive of this identified subset of transmission resources. The device (16A) in some embodiments obtains information indicating that the base station (20A) is selectively transmitting user data upon the first carrier (22) exclusive of the subset in this way. Based on this information, the device (16A) recovers user data received upon the first carrier (22) exclusive of the subset of transmission resources.

Abstract: 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-uniform!y 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.

Abstract: Accurate downlink channel estimates are calculated based on infrequently transmitted Channel State information (CSI) feedback data from a UE 20. A plurality of non-uniformly spaced digital CSI feedback samples, representing the frequency response of a downlink communication channel, is received from the UE, The received CSI feedback samples are demodulated and inverse quantized. A time domain tap delay channel model is generated from the inverse quantized CSI feedback samples. The time domain tap delay channel model may be frequency-transformed to obtain a reconstructed frequency response of the downlink communication channel in the frequency domain. Alternatively, channel delays may be estimated based on prior delays and/or known references signals transmitted on the uplink. Channel estimates between CSI reporting instances may be predicted, such as by a sample & hold or a linear predictor. The delays may be presumed fixed, and Kalman filter coefficients evolved over time.

Abstract: A wireless communication receiver improves signal impairment correlation estimation in MIMO/MISO systems by considering different transmit power allocations and different transmit antenna power distributions in its impairment correlation calculations. The receiver may be implemented in according to a variety of architectures, including, but not limited to, Successive Interference Cancellation (SIC) Generalized RAKE (G-RAKE), Joint Detection (JD) G-RAKE, and Minimum Mean Squared Error (MMSE) G-RAKE. Regardless of the particular receiver architecture adopted, the improved impairment correlations may be used to calculate improved (RAKE) signal combining weights and/or improve channel quality estimates for reporting by receivers operating in Wideband CDMA (W-CDMA) systems transmitting HSDPA channels via MIMO or MISO transmitters. A transmitter may be configured to facilitate impairment correlation determinations by wireless communication receivers operating in MIMO/MISO environments, by signaling one or more values, e.g., data-to-pilot signal transmit power ratios and/or transmit antenna power distributions for the data and pilot signals.

Abstract: A CDMA communication system uses a RAKE receiver, a code correlator and a multi-code joint detector to jointly detect symbols in two or more received signals contained within a composite signal. The RAKE receiver separates the composite signal into two or more RAKE output signals by despreading the composite signal using selected spreading codes. The multi-code joint detector jointly detects the symbols in the received signals using the RAKE receiver output signals, cross-correlations between the spreading codes generated by the code correlator, and RAKE combining weights based on a noise covariance matrix. The multi-code joint detector also includes a trellis that represents possible states and state transitions and a branch metric calculator for calculating branch metrics associated with the state transitions based on the RAKE receiver output signals and the cross-correlations between the spreading codes.

Abstract: Channel-state information and hybrid-ARQ ACK/NACK information for multiple carriers are simultaneously transmitted using a PUCCH Format 3 structure, where the hybrid-ARQ ACK/NACK bits and CSI bits are separately encoded and interleaved. In an example method, a power control offset parameter is calculated (2110) as a linear combination of at least a number N, representing a number of channel-state information bits and a number M, representing a number of hybrid-ARQ ACK/NACK bits. The method continues with the calculating (2120) of a power level for a transmission on a physical uplink control channel (PUCCH), using the power control offset parameter. In some embodiments, encoded channel-state information and hybrid- ARQ ACK/NACK bits are then transmitted (2060) according to the calculated power level. In some embodiments, the linear combination is of the form aN + bM + c, where a, b, and c are non-zero constants.

Abstract: In one aspect, the teachings herein provide a method and apparatus for extending certain HARQ feedback procedures introduced in LTE Rel-10, which were defined for CA configurations involving TDD serving cells of the same UL/DL configuration, to the new, more complex CA configurations introduced in Rel-11, which involve the aggregation of interband TDD serving cells with differing UL/DL configurations. Such reuse enables reliant and efficient HARQ feedback signaling in LTE Rel-11, without substantially increasing the specification or implementation complexity of HARQ feedback signaling in LTE Rel-11, despite the decidedly more complex CA configurations introduced in LTE Rel-11.
