摘要： A method sends uplink control information from a user equipment to a serving node of a radio communications system by first encoding uplink control information bits into symbols. The encoded symbols are split into at least two groups of symbols for use to achieve diversity transmission. Each of the at least two groups of symbols are cyclically repeated to generate a repeated group for each of the at least two groups of symbols. Then the repeated groups are mapped each to different transmission ports of the user equipment for diversity transmission as uplink control information through a plurality of uplink transmission slots of an uplink subframe.

摘要： A receiver separates multiple component signals carried in a composite signal that have been spread over time and frequency. Multiple diversity branches receive the composite signal. A tensor generation circuit arranges samples of that signal along time, frequency, and diversity dimensions to obtain a composite signal tensor. A set of cascaded least squares estimators then separates the component signals by fitting a constrained tensor model of the composite signal to the composite signal tensor in an alternating least squares estimation process, alternating during any given iteration of the process between fitting different unfolded representations of the constrained tensor model to corresponding unfolded representations of the composite signal tensor. The tensor model models the composite signal as a linear combination of rank-one tensors associated with the component signals, and is constrained in the sense that each rank-one tensor remains constrained according to the spreading of its associated component signal over time.

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 use in downlink carrier transmissions. Furthermore, 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. Also, the control information comprises a first bit or symbol sequence and at least a second bit or symbol sequence. The user equipment arranges the first bit or symbol sequence and the at least second bit or symbol sequence, such that at least two bits or symbols from the first bit or symbol sequence and at least second bit or symbol 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.A user equipment, a method in network node and a network node are also provided.

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.

摘要： Method and arrangement in a serving base station for determining a binary value of information data received from a user equipment, by using a supportive likelihood value received from a supporting base station. The user equipment transmits information data to be received both by the serving base station and the supporting base station base station. The method comprises: decoding information data bits received from the user equipment into a first likelihood value, without determining a binary value for each bit of the information data, a supportive likelihood value of the information data bits transmitted from the user equipment is received from the supporting base station, which supportive likelihood value is based on a decoding of the information data bits performed in the supporting base station. The first likelihood value of the decoded information bits is combined with the received supportive likelihood value of the decoded information bits. Thus a binary value for each bit of the information data transmitted from the user equipment is determined, based on the combined first and supportive likelihood values.

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： Methods and apparatus for generating, transmitting, and processing error control information in a wireless communication system are disclosed. The error control information is designed so that the probability of a NACK-to-ACK error in transmission is lower than the probability for an ACK-to-NACK error. Multiple ACK/NACK bits are transmitted along with one or more side information bits that indicate the relative quantities of ACK values and NACK values among the ACK/NACK bits. In an exemplary method for generating error control information in a communication device, a plurality of ACK/NACK bits indicating whether corresponding transport blocks were successfully received are generated. One or more side information bits are formed as a function of the ACK/NACK bits, the side information bits indicating the relative quantities of ACK values and NACK values among the ACK/NACK bits, and transmitted along with the ACK/NACK bits to the remote communication node.
