摘要： A system and method for determining a Physical Uplink Control Channel (PUCCH) power control parameter h(nCQI,nHARQ) for two Carrier Aggregated (CA) PUCCH formats—PUCCH format 3 and channel selection. The value of h(nCQI,nHARQ) may be based on only a linear function of nHARQ for both of the CA PUCCH formats. Based on the CA PUCCH format configured for the User Equipment (UE), the e-Node B (eNB) may instruct the UE to select or apply a specific linear function of nHARQ as a value for the power control parameter h(nCQI,nHARQ), so as to enable the UE to more accurately establish transmit power of its PUCCH signal. Values for another PUCCH power control parameter—ΔF—PUCCH(F)—are also provided for use with PUCCH format 3. A new offset parameter may be signaled for each PUCCH format that has transmit diversity configured.

摘要： In various embodiments, a method for transmitting uplink control information in a cell is provided. The uplink control information is transmitted during a time slot. According to this method, bits corresponding to uplink control information are mapped to complex modulation symbols. The complex modulation symbols are spread in the time slot using a set of orthogonal cover code, OCC, sequences, such that at least two of the complex modulation symbols are spread using different OCC sequences. The uplink control information is then transmitted using said spread complex modulation symbols.

摘要： A method in a user equipment for arranging a Physical Uplink Control Channel, PUCCH, transmission to a network node in a telecommunications system is provided. The PUCCH transmission comprises control information for downlink transmissions. The control information is Reed-Müller, RM, encoded using at least two RM codewords and transmitted using Alamouti encoded transmit diversity over at least two antenna ports. The control information comprises a first bit sequence and a second bit sequence. The user equipment arranges the first bit sequence and the second bit sequence, such that at least two bits from the first bit sequence and second bit sequence, that subsequently are Alamouti encoded together, originates from the same RM codeword of the at least two RM codewords. This is performed in order to enable control information encoded using one RM codeword to be processed independently from control information encoded using another RM codeword at the network node.

摘要： A wireless communication node (10) dynamically estimates passive intermodulation (PIM) interference coupled into the node's receive path from the transmission of a composite signal through the node's transmit path. The node (10) then cancels the estimated PIM interference in the receive path. In some embodiments, the node dynamically estimates the PIM interference as a function of the composite signal that models PIM interference generation and coupling in the node (10) according to one or more coefficients (30). The coefficients (30) may be determined by transmitting a test signal (34) during a test stage, when the node (10) is not scheduled to receive any signal. Later, when the composite signal (18) is transmitted, the node (10) uses the coefficients (10) to dynamically estimate and cancel the resulting PIM interference.

摘要： In a communication system using HARQ, the problem of false ACK detection when no ACK/NACK feedback is transmitted is solved sent by varying the reliability of the scheduling information transmitted to the user terminal on a downlink control channel depending on whether the user terminal is expected to use a first or second uplink channel for sending ACK/NACK feedback. When the user terminal is expected to use the first channel to send ACK/NACK feedback, the base station transmits scheduling information to the user terminal with normal reliability. When the user terminal is expected to send ACK/NACK feedback on the second uplink channel, the base station transmits the signaling information to the user terminal with enhanced reliability. The reliability of the signaling information can be increased, for example, by increasing the transmit power on the downlink control channel, increasing the aggregation level, or a combination thereof.

摘要： 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.

Balance is maintained by attenuating the influence of extrinsic information fed back from the decoder to the demodulator to prevent strong decisions by the decoder from overwhelming the demodulator.

摘要： A frontend module for Time Division Duplex (TDD) with Carrier Aggregation (CA), wherein the frontend module reuses the band selection filters for the aggregated bands and provides switched connections to antenna and transmitter/receiver according to the Uplink (UL)/Downlink (DL) configuration. The use of switches on both the antenna side and the transmitter/receiver side of the frontend module enables the reuse of the band selection filters. The frontend module according to the present invention reduces the number of required filters to only one filter for each TDD-CA Component Carrier (CC) band. Thus, the frontend module avoids unnecessary band selection filters, and thereby also controls the cost of implementation of frontend modules in wireless units operating in the TDD-CA mode.
