摘要： Error protection based on a nonlinear code set may be used in a multiple input multiple output (MIMO) radio communications system. A decoder decodes received MIMO data streams and generates an automatic repeat request (ARQ) message for data units received for the MIMO data streams for each transmission time interval. An encoder codes the ARQ message using a code word from a nonlinear code set. At the data transmitter, which transmits one or more data units in transmission time intervals from two or more MIMO data streams, the ARQ message associated with the transmitted data units is decoded using a code word from the nonlinear code set.

摘要： In MU-MIMO scenarios, a target mobile terminal can be exposed to data streams intended for other mobile terminals. If the target mobile terminal is capable of interference cancellation, then a serving base station can provide the target mobile terminal with interference information so that the target mobile terminal can efficiently cancel interferences due to these interfering data streams. The interference information includes one or more configuration information, each of which characterizes a related interfering data stream. The serving base station provides the interference information over one or more radio resources that are exclusive allocated to the target mobile terminal or are allocated for common listening. The serving base station exchanges configuration information with neighboring base stations over inter-BS links. The inter-BS links use resources that are different from the radio resources used between the base stations and the mobile terminals.

摘要： Methods for improving uplink communications in a Wideband Code Division Multiple Access (WCDMA) communication system, wherein mobile terminals can transmit at various transmission power levels. In a mobile terminal, the method includes the steps of receiving a configuration message having at least one of a power offset parameter and a maximum number of retransmission attempts parameter; when the mobile terminal performs a non-scheduled transmission, it transmits according to the parameters contained in the configuration message. In a network node, the method includes the steps of transmitting to at least one mobile terminal the configuration message having at least one of a power offset parameter and a maximum number of retransmission attempts parameter; and, adjusting a power setting for the transmission of acknowledgement or negative-acknowledgement messages from the wireless network to one or more of mobile terminals.

摘要： A system and method for determining a downlink transmit power level for a downlink signaling channel such as the E-DCH HARQ Indicator Channel (E-HICH) in a cellular radio communication network, wherein the transmit power level is calculated to achieve a desired signaling message error rate. The base station determines a diversity order of an uplink control channel from a mobile station, and sets the downlink E-HICH transmit power based on the desired signaling message error rate and the diversity order of the uplink control channel. Optionally, the base station may first determine whether the cell transmitting the E-HICH is the serving cell for the High-Speed Downlink Shared Channel (HS-DSCH). If so, the base station determines the downlink transmit power level for the downlink signaling channel as an offset from the reported Channel Quality Indicator (CQI) value.

摘要： A method and apparatus for code multiplexing one or more control signals onto a shared control channel. According to the present invention, a control signal for transmission from a base station to a mobile station terminal is repeated in each slot of a predetermined time interval. The control signal in each slot is spread using a bit-level spreading sequence, where the bit-level spreading sequence varies from slot to slot according to a predefined sequence-hopping pattern. The spread control signals generated for transmission to each mobile station terminal are then combined and spread using a common channelization code.

摘要： A radio network controller, RNC, 614, and a method therein, for enhancing reception quality of transmissions on an uplink control channel from a user equipment, UE, 613 to a serving base station, BS, 610. The RNC, the UE and the serving BS are comprised in a communication system 600. The method comprises, when conditions for boosting the uplink control channel are fulfilled, determining a boosting factor based on a ratio of path gains of a channel from the UE to the serving BS and of a channel from the UE to a non-serving BS 611, respectively, which non-serving BS is comprised in the communications system. The method further comprises transmitting the determined boosting factor to the UE, whereby the reception quality of transmission on the uplink control channel from the UE to the serving BS is enhanced by the UE boosting the control channel by means of the boosting factor.
