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. 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： 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.

摘要： User Equipment (700) reports single-cell or multi-cell channel state information to a base station (600) on a PUCCH Format 3 resource. The PF 3 resource selected depends on whether ACK/NACK needs to be reported simultaneously. Different coding and/or scrambling and/or Interleaving schemes are used depending on whether ACK/NACK bits are present, as well as the number of ACK/NACK and/or CSI bits. Resource compatibility is maintained independently of the details of coding, interleaving, or scrambling - that is, all formats can be orthogonally multiplexed onto the same time-frequency resources. The format used for CSI only is PUCCH Format 3c (PF 3c) whereas the PUCCH Format used for CSI and ACK/NACK is PUCCH Format 3b (PF 3b). PUCCH Formats 3b and 3c may be further differentiated depending on whether a CSI from a single or multiple cells are reported, or from which cells (PCell, SCeil) an ACK/NACK is reported. Ambiguity may be resolved by using different spreading codes for reference signals In PF 3b and 3c formats.

摘要： A method sends uplink control information from the user equipment to a serving node of a radio communications system by first encoding (1413) uplink control information bits into symbols. The encoded symbols are split (1415) 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 (1417) to generate a repeated group for each of the at least two groups of symbols. Then the repeated groups are mapped (1421) each to different transmission ports of the user equipment for diversity transmission as uplink control information through a plurality of uplink transmission slots of the uplink subframe.

摘要： 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.

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) sub frames 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 Ia or PUCCH format Ib. 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： In a communication system using HARQ1 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.
